Definitions
- the invention relates to a verywindablenkelement with the features of the preamble of claim 1, which is used for installation in open terrain, especially at wind critical points such as mountain ridges or the like. If strong side winds occur at such locations in the terrain, there is often deposition of airborne solids, such as drift sand or snow. Such snow deposits can be a danger through the formation of snow avalanches, for example, on hilltops in winter, if the deposits are not deliberately broken down again, for example by repeated blasting. A regular blasting away of dangerous snow overhangs in the mountains, however, is costly and not always sufficient to effectively prevent the emergence of avalanches.
- snow fences have been used in the prior art for influencing unwanted snow accumulations generated by the wind.
- These fences which are set up at critical points in the field, deliberately cause snow accumulation to prevent snow or sand from being blown onto a road or similar.
- Such fences are unsuitable for effectively preventing accumulation of particulate matter from the air by a strong crosswind, so-called sedimentation, in any situation.
- the conventional other proposed in the prior art avalanche elements for installation at critical points in the mountains have either a deflection or a refraction of outgoing snow avalanches or scree avalanches to the content. That is, they are not suitable for purposefully preventing the emergence of such scree avalanches or snow avalanches.
- WO82 / 01204A and CH338854A reveal side baffles with baffles for deflecting the wind.
- the present invention is based thereon on the object to provide a crosswind baffle element for installation in open terrain, with which a targeted prevention of the deposition of solids from the air is possible.
- the iswindablenkelement according to the invention is to make fire as easy as possible and be mounted in the field.
- the The iswindablenkelement invention which is intended for installation in open terrain for targeted prevention of deposition of snow, sands or the like, has a bottom-side base plate for anchoring in the field, a towering from the base plate central post and a plurality of mounted on the post guide plates Deflection of the wind and is characterized in that the guide plates are provided in a vertical orientation cross-shaped abkragend the post and that increases the length of the guide plates, starting from the base plate upwards.
- the wind deflecting and deliberately redirecting guide plates of the crosswind baffle element are thus provided projecting in a vertical orientation of the post, so that they form the largest possible attack surface for occurring crosswinds.
- the length of the guide plates is lower in the lower region and increases towards the top, so that a kind of trapezoidal shape is formed whose width is greater at the top than at the lower end of the crosswind deflection element.
- All baffles are mounted on a central, uprising post, so that the crosswind baffle can be self-supporting and freestanding without additional anchoring ropes or the like can be mounted.
- a base-side base plate is provided, on which the central post is fixedly mounted. The baseplate serves to set up and anchor the element in the ground at the point in the terrain where targeted prevention of sedimentation of solids from the air is desired.
- the crosswind deflector has a surface which is enlarged toward the top and opposes the impinging wind.
- the crosswinds are targeted and reinforced intercepted and directed in a kind of nozzle effect with the formation of amplified vertebrae down.
- the crosswind baffle element according to the invention is set up at critical points in the mountains, for example at mountain ridges or hilltops, the formation of avalanches due to undesirable local deposits can be prevented with comparatively simple means, since the wind entrained solids do not settle at the points of installation of crosswind deflectors, but are further carried away with the targeted deflected wind.
- the The iswindablenkelement according to the invention thus prevents the formation of undesirable deposits (sedimentation) in open terrain in a relatively simple structural design. This can either be a deposit of shifting sand or a deposit of snow.
- the crosswind baffle element according to the invention can preferably be set up in groups of several such crossbeam baffles at corresponding problematic terrain sites. Each of the elements is extremely robust due to the central post and can be installed freestanding. The installation and assembly of the crosswind baffles is thereby comparatively simple, since only for the central post a foundation or a counter plate in the field must be prepared in advance.
- the wind deflectors formed by the baffles of the crosswind baffle element are thus provided comparatively large area, but have a certain permeability through the interstices.
- this has the advantage that the elements do not form a full-surface barrier and allow a look through. The intervention in nature is thus comparatively small.
- the elements are less prone to damage by very strong winds through the spaces between the baffles, which can often occur especially in the mountains. A long-term positioning and stability of the elements is guaranteed.
- the gaps may in particular be half the width of the guide plates, so that a sufficiently large deflection surface is still ensured for the winds impinging there, which leads to the turbulences at the bottom due to the nozzle effect and a reliable prevention of local sedimentation guaranteed.
- the guide plates are at least at their free ends coupled together so that they form four sail-like from the post cross-shaped projecting wind deflectors.
- From Individual elements existing baffles are thus securely interconnected and coupled so that they form despite their permeability, a common, stable component for the purpose of targeted diversion of winds.
- a coupling of the individual guide plates can be done for example by a rigid connection such as welding with rods or profile elements.
- a coupling can also be carried out via flexible elements, such as wire ropes or the like.
- the coupled baffles each protrude crosswise from the central post and form a kind of trapezoidal sail, with a greater width at the top of the element than on the sides of the bottom.
- cross-shaped projecting from the post upper and lower cross member for holding and additional securing the guide plates are provided.
- the laterally projecting guide plates can be securely and firmly fixed without greatly increasing the weight of the entire member.
- the baffles can namely be provided, for example, as very thin metal sheets, which themselves have no great intrinsic stability, but in interaction with the cross members, which may be configured for example in the form of tubular profiles, have the necessary strength against the impinging winds even in strong winds.
- the holder and the installation of the guide plates between the cross members can be done in different ways: by solid welding to longitudinal bars, by inserting the guide plates in recesses, by holding clamped between the cross members cables or the like.
- the base plate on which the post is mounted vertically towering formed in two parts and provided with an erection aid, preferably of the tube-in-tube type plug-in system.
- the base plate may for example consist of a first element plate and a second bottom plate, wherein the element plate is firmly connected to the post and the bottom plate is provided for installation in the ground.
- the bottom plate may be made of metal and / or a combination of metal and a concrete material, so that a secure foundation for the deployed crosswind deflector is given.
- an erection aid for example, provided in the manner of a pipe plug system:
- the bottom plate has for this purpose, for example, a smaller diameter pipe on which the slightly larger diameter in the pipe the post of the 9.windablenkelements can be simply plugged from above.
- the position is thus securely fixed already at the first shutdown of the sowindablenkelements, and an assembly requires only, for example, a screwing of the two plate elements of the base plate together. This facilitates above all a mounting in rough terrain via a helicopter through the air. Only a single worker on the ground is required. The necessary intervention in nature is also minimal.
- the guide plates or the four Windleitiata formed from the guide plates are additionally secured with upper and / or lower struts at the top and / or bottom of the post.
- the struts can be realized for example by ropes or rods running obliquely from a free end or a central region of the guide plates or the cross member to the central post. Such bracing further increases the stability and resistance to hitting winds. Without a large increase in the weight of the element, a very robust structure for the purpose of wind diversion can be achieved.
- a strut may for example consist of tensioned wire ropes, which are attached to connecting flanges. However, the struts in the present context may also be in solid form, for example by welded rods executed.
- the advantage of the compact and comparatively lightweight construction of the crosswind baffle element is further that it can be self-erected in the field, d. H. does not require troublesome lateral anchorages by wire ropes or the like, which would require multiple anchoring points and concrete foundations or the like in each case.
- the guide plates consist of the wind catching and diverting guide plates made of profiled or ribbed sheets in the longitudinal direction of a metal material.
- the guide plates can be made of comparatively thin sheet material and are therefore very light. This leads to a total lightweight construction of the entire crosswind baffle element, which is especially for transport by means of a helicopter for installation in rough terrain advantage.
- the guide plates with the profiles or the reinforcing ribs in the longitudinal direction are also sufficiently stable, so that bending by high winds can be prevented.
- the guide plates are fixedly mounted in a respective peripheral frame, which in turn is attached to the post.
- the four, for example, laterally projecting in a cross-shape guide plates are thus each firmly assembled within a frame and form a compact unit.
- the frame can consist of welded tube profiles and increases the stability and strength of the element.
- the guide plates themselves are securely fixed in their respective frame at the desired position.
- the mounting of the frame itself to the central post can for example be done in a detachable manner by screw with corresponding flanges or the like.
- the respective guide plates of a group of guide plates, which form a common Windleitelement connected to each other via coupling cables between the upper and lower cross members and secured in position.
- a first coupling cable between an upper and lower cross member can be stretched, and there may be in the middle region, a coupling cable or more coupling ropes, each holding the guide plates in the four directions and in the desired vertical orientation.
- a rotation lock for torsion-proof installation of the element is provided.
- a rotation lock can be realized for example by a pin or bolt on the bottom plate, which engages in a corresponding hole.
- Other means for anti-rotation are also conceivable.
- the anti-rotation device has the advantage that the Sowindablenkelement can not rotate in the position depending on the impact of the crosswinds, so that a strong turbulence of the crosswinds and a targeted discharge to the bottom side are always guaranteed.
- means are provided for preventing rotation of the element during transport by helicopter or the like through the air.
- the crosswind deflector can thus be easily picked up by a hook from a helicopter and safely transported through the air to the mounting location. Even when lifting with a crane this prevents twisting.
- a means for preventing the rotation of the Elements in transit in the air can be designed, for example, in the form of a projecting rod with a windsock at the free end. The rod protrudes laterally from the The Windablenkelement and has at its end the Windhose or windsock, so that the element thereby remains in the respective position and can not rotate in the air.
- Other means of preventing rotation of the element during airborne transport may also be provided.
- the length of the guide plates from bottom to top is increased to almost twice. That is, the bottom guide plate is approximately half the length of the top guide plate.
- the area for the targeted deflection of the impinging winds is thus increased relatively large from bottom to top, whereby an even better deflection, diversion and turbulence due to the aforementioned nozzle effect is achieved with the crosswindow element according to the invention. An even better prevention of the deposition of solids in the area and within the 9.
- a first embodiment of a cross wind deflector 10 according to the invention as shown in different views in the Fig. 1 . 2a and 2b will be explained below.

- This Windleitieri 30 are used for targeted interception, swirling and dissipating the incident crosswinds down in the area around the sowindablenkelement 10 around, so that a deposition of solids from the air, such as dry sand or snow, is specifically prevented.
- the guide plates 3 between upper and lower cross members 4, 5 are mounted in the form of square tube profiles by means of coupling cables 9.
- the coupling cables 9 are attached to mounting flanges on the tube profiles of the cross members 4, 5 and hold the respective guide plates 3 in their desired position and location.
- the guide plates 3, which may for example be made of a thin metal sheet, are each mounted at a distance from one another such that in each case gaps of approximately half the width of the guide plates 3 arise.
- the iswindablenkelement 10 is thus not completely closed and allows a look through.
- the spaces between the guide plates 3 have the advantage that the elements 10 are not at risk in very strong winds, torn or damaged by the wind.
- the central post 2 protrudes slightly beyond the upper cross member 4, which form the conclusion of the wind deflector 30.
- respective struts 6, 7 are mounted between the lower and upper end of the post 2 and approximately at the center of the cross members 4, 5.
- the struts 6, 7, which may be designed, for example, in the form of tensioned wire ropes or iron bars, increase the stability of the crosswind deflector 10 without unduly increasing the overall weight.
- the struts 6, 7 are also used to hold the applied by means of the coupling cables 9 tensile stress, so that the wind deflectors 30 are clamped in the form of a kind of sail with upwardly increased width.
- the four of the post 2 cross-shaped projecting cross member 4, 5 are each also mounted on mounting flanges and corresponding fittings.
- the cross members may also be fixedly connected to the post 2, for example by welding metal pipes.
- the detachable mounting on mounting flanges and fittings has the advantage that the transport of the Sowindablenkieri 10 is facilitated and less volume is needed here.
- the cross wind deflector 10 according to the invention is provided with comparatively large surfaces for the impact, deflecting and targeted forwarding of the winds. By in four Direction of crosswise projecting guide plates 3, a deposition of solids from the air is ensured even in changing wind directions.
- the wind can impinge on the cross wind deflector 10 from all directions without the deposition of, for example, snow or sand at the rear (windward side), as is the case with conventional fences or the like, for stopping snow drifts, for example be set up on the edge of overland roads in winter.
- Fig. 3 is shown in a side view of a second embodiment of the invention to windablenkelements 10.
- the guide plates 3 are mounted on a peripheral frame 8, wherein the frame 8 is then mounted by the four cross-shaped projecting wind deflectors 30 in total at the central post 2 via corresponding mounting flanges and fittings.
- the guide plates 3 are, for example, welded into the frame 8. Again, each upper and lower cross member 4, 5 are provided, which form the frame 8 together with a slightly thinner rod or profile at the ends of the guide plates 3.
- This form of Windleitmaschine 30 has the advantage that the individual guide plates 3 are securely held together and fixed in position.
- Fig. 3 is shown on the left hand and right hand a variant of this embodiment.
- a strut 6 between the free end of the cross member 4 and the upper end of the post 2 and no lower strut is provided, in the right example, as in the first embodiment, an upper strut 6 and a lower strut 7 are present which are fixed between the post 2 and approximately the middle of the respective cross member 4, 5 and provide additional stability.
- the struts can be omitted entirely - both in this and in the first embodiment.
- the guide plates 3 of the crosswind deflector 10 are made of a relatively thin sheet metal material.
- the sheet material may be provided with longitudinal profiling or struts for stiffening, so that the guide plates 3 despite the relatively thin material yet have sufficient strength to oppose different degrees of wind situations, and the desired effect by the turbulence and dissipation of the wind Provide below to prevent sedimentation.
- the other components of the sowindablenkelements 10 may also preferably here from a Be made of metal material.
- the central post 2 is executed in the embodiments shown as a round tube. Alternatively, however, it may be realized as a square tube, as are the upper and lower cross beams 4, 5 in these embodiments.
- the lower end of the post 2 is provided with a base plate 1, which is reinforced by stiffening triangular struts.
- the base plate 1 has holes for mounting via screws.
- the situation of a mounting of the crosswind baffle element 10 according to an embodiment of the invention in place is in a schematic side view of the other Fig. 4 shown.
- FIG. 4 the situation is shown in which the crosswind deflector 10 is carried through the air by a helicopter or crane (not shown) just before being parked at the desired off-road position.
- a helicopter hook 14 is mounted at the upper end of the element 10.
- the cross wind deflector 10 is provided for transport with a means 11 for preventing rotation of the element 10 in the air, here shown in the form of a wind trouser or windsock 11, which is mounted over a laterally projecting from the lower cross member 5 rod.
- the crosswind baffle 10 is safely conveyed through the air and deposited at the desired location in the field by a simple lowering by means of the helicopter.
- a foundation plate 16 made of concrete was previously installed for this purpose, on which a bottom plate 13 is mounted, on which the element plate 12 of the base plate 1 is placed.
- the bottom plate 13 is provided with a central pipe socket 15, which is somewhat smaller in diameter than the inner diameter of the central post 2.
- the two plates 12, 13 of the base plate 1 can thus be in the form of a pipe socket.
- In-tube plug-in system are placed on each other, so that the Sowindablenkelement is already in the correct position directly on weaning and is secured in advance.
- the invention provides an effective crosswind baffle element 10 which avoids solids deposits from the air in place, directly and safely, on a large scale due to the turbulence and targeted transmission of the wind.
- the cross wind deflector 10 according to the invention due to its construction with a plurality of relatively thin guide plates 3, which project crosswise from a central post 2, a very low weight, so that a transport by helicopter is made possible.
- the total weight of the crosswind deflector 10 is preferably less than 550 kg.
- the cross wind deflector 10 according to the invention represents a relatively minor intervention in nature, since the elements must be placed only at certain points in groups and no large-scale construction measures to prevent snow avalanches, scree avalanches or deposits of blasting sand are required.
- the shape of the baffles may vary.
- the length of the bottom guide plate 3 in relation to the top guide plate 3 in about half so large, so that a comparatively strong broadening of the wind deflector 30 is given upwards.
- the broadening upwards can also be made smaller or stronger.
- the guide plates 3 can be made with smooth or profiled sheets, ie with relatively thin sheets, which have stiffening in the longitudinal direction deformations. But the guide plates 3 can also be provided with stiffening ribs, so that the high stability is ensured despite the lightweight construction.
- the guide plates 3 can also be fixed differently to the central post 2 than in the illustrated embodiments with coupling ropes 9 and a peripheral frame 8, for example.
- the guide plates 3 can be mounted by receiving slots in the post 2 and a fixed welding. Also, the distance between the guide plates 3 to each other can be varied, for example, to selectively effect a greater permeability in certain areas: for example, the upper guide plates 3 at a greater distance from each other than the lower guide plates 3 be mounted near the ground to account for the stronger winds in the upper area.

Description
Die Erfindung betrifft ein Seitenwindablenkelement mit den Merkmalen des Oberbegriffs des Anspruchs 1, welches zur Aufstellung im freien Gelände, insbesondere an windmäßig kritischen Punkten wie Bergkämmen oder ähnlichem, dient. Wenn an solchen Stellen im Gelände starke Seitenwinde auftreten, kommt es häufig zu einer Ablagerung von in der Luft mitgetragenen Feststoffen, wie zum Beispiel Flugsand oder Schnee. Solche Schneeablagerungen können beispielsweise an Bergkuppen im Winter zu einer Gefahr durch die Bildung von Schneelawinen werden, wenn die Ablagerungen nicht beispielsweise durch wiederholte Sprengungen gezielt wieder abgebaut werden. Ein regelmäßiges Wegsprengen von gefährlichen Schneeüberhängen im Gebirge ist jedoch aufwendig und nicht immer ausreichend, um die Entstehung von Lawinen effektiv zu verhindern.The invention relates to a Seitenwindablenkelement with the features of the preamble of claim 1, which is used for installation in open terrain, especially at wind critical points such as mountain ridges or the like. If strong side winds occur at such locations in the terrain, there is often deposition of airborne solids, such as drift sand or snow. Such snow deposits can be a danger through the formation of snow avalanches, for example, on hilltops in winter, if the deposits are not deliberately broken down again, for example by repeated blasting. A regular blasting away of dangerous snow overhangs in the mountains, however, is costly and not always sufficient to effectively prevent the emergence of avalanches.
Bisher wurden im Stand der Technik auch sogenannte Schneezäune zur Beeinflussung von durch den Wind erzeugten unerwünschten Schneeansammlungen verwendet. Diese im Gelände an kritischen Stellen aufgestellten Zäune verursachen gezielt eine Ansammlung von Schnee, um zu verhindern, dass beispielsweise der Schnee oder Flugsand auf eine Straße oder ähnliches geweht wird. Solche Zäune sind jedoch ungeeignet, um eine Ansammlung von Feststoffen aus der Luft durch einen starken Seitenwind, sogenannte Sedimentationen, tatsächlich in jeder Situation zu verhindern. Die herkömmlichen weiteren im Stand der Technik vorgeschlagenen Lawinenelemente für die Aufstellung an kritischen Stellen im Gebirge haben entweder eine Umlenkung oder eine Brechung von abgehenden Schneelawinen oder Gerölllawinen zum Inhalt. Das heißt, sie sind nicht für eine gezielte Verhinderung der Entstehung derartiger Gerölllawinen oder Schneelawinen geeignet.
Die vorliegende Erfindung beruht hiervon ausgehend auf der Aufgabe, ein Seitenwindablenkelement für eine Montage im freien Gelände bereitzustellen, mit welchem eine gezielte Verhinderung der Ablagerung von Feststoffen aus der Luft möglich ist. Das Seitenwindablenkelement gemäß der Erfindung soll feuer möglichst einfach herzustellen und im Gelände montierbar sein.The present invention is based thereon on the object to provide a crosswind baffle element for installation in open terrain, with which a targeted prevention of the deposition of solids from the air is possible. The Seitenwindablenkelement according to the invention is to make fire as easy as possible and be mounted in the field.
Diese Aufgabe wird mit einem Seitenwindablenkelement gemäß den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved with a crosswind baffle element according to the features of claim 1. Advantageous embodiments and modifications of the invention are the subject of the dependent claims.
Das erfindungsgemäße Seitenwindablenkelement, welches für eine Montage im freien Gelände zur gezielten Verhinderung einer Ablagerung von Schnee, Flugsand oder ähnlichem vorgesehen ist, weist eine bodenseitige Grundplatte zur Verankerung im Gelände, einen von der Grundplatte aufragenden zentralen Pfosten sowie eine Mehrzahl von am Pfosten montierten Leitplatten zur Ablenkung des Windes auf und ist dadurch gekennzeichnet, dass die Leitplatten in vertikaler Ausrichtung kreuzförmig abkragend am Pfosten vorgesehen sind und dass die Länge der Leitplatten von der Grundplatte ausgehend nach oben hin zunimmt. Die den Wind abfangenden und gezielt umleitenden Leitplatten des Seitenwindablenkelements sind somit in vertikaler Ausrichtung von dem Pfosten vorragend vorgesehen, so dass sie eine möglichst große Angriffsfläche für auftretende Seitenwinde bilden. Die Länge der Leitplatten ist im unteren Bereich geringer und nimmt nach oben hin zu, so dass eine Art trapezoide Form gebildet wird, deren Breite oben größer ist als am unteren Ende des Seitenwindablenkelements. Sämtliche Leitplatten sind an einem zentralen, aufragenden Pfosten montiert, so dass das Seitenwindablenkelement selbsttragend und freistehend ohne zusätzliche Verankerungsseile oder ähnliches montiert werden kann. Für die Montage und Aufstellung des erfindungsgemäßen Seitenwindablenkelements ist eine bodenseitige Grundplatte vorgesehen, an welcher der zentrale Pfosten fest angebracht ist. Die Grundplatte dient dem Aufstellen und Verankern des Elements im Boden an der Stelle im Gelände, an welcher eine gezielte Verhinderung von Ablagerungen von Feststoffen aus der Luft erwünscht ist. Durch die nach oben hin länger werdenden Leitplatten weist das Seitenwindablenkelement eine nach oben hin vergrößerte Fläche auf, die sich dem auftreffenden Wind entgegenstellt. Durch diese erfindungsgemäße Maßnahme werden die Seitenwinde gezielt und verstärkt abgefangen und in einer Art Düseneffekt unter Bildung von verstärkten Wirbeln nach unten geleitet. Diese verstärkten Wirbel im Bereich des Seitenwindablenkelements verhindern effektiv die Ablagerung von Feststoffen aus der Luft, wie zum Beispiel Sand oder Schnee. Wenn das erfindungsgemäße Seitenwindablenkelement an kritischen Stellen im Gebirge, beispielsweise an Bergkämmen oder Bergkuppen, aufgestellt wird, kann so mit vergleichsweise einfachen Mitteln die Entstehung von Lawinen aufgrund unerwünschter lokaler Ablagerungen verhindert werden, da die mit dem Wind mitgeführten Feststoffe sich an den Stellen der Aufstellung der Seitenwindablenkelemente nicht ablagern, sondern mit dem gezielt umgelenkten Wind weiter fortgerissen werden. Das Seitenwindablenkelement gemäß der Erfindung verhindert somit in einer vergleichsweise einfachen konstruktiven Bauart die Entstehung von unerwünschten Ablagerungen (Sedimentationen) im freien Gelände. Dabei kann es sich entweder um eine Ablagerung von Flugsand oder um eine Ablagerung von Schnee handeln. Das erfindungsgemäße Seitenwindablenkelement kann vorzugsweise in Gruppen von mehreren derartigen Seitenwindablenkelementen an entsprechenden windmäßig problematischen Geländestellen aufgestellt werden. Jedes der Elemente ist in sich aufgrund des zentralen Pfostens äußerst robust und kann freistehend installiert werden. Die Aufstellung und Montage der Seitenwindablenkelemente ist dadurch vergleichsweise einfach, da lediglich für den zentralen Pfosten ein Fundament oder eine Gegenplatte im Gelände vorab hergestellt werden muss.The Seitenwindablenkelement invention, which is intended for installation in open terrain for targeted prevention of deposition of snow, sands or the like, has a bottom-side base plate for anchoring in the field, a towering from the base plate central post and a plurality of mounted on the post guide plates Deflection of the wind and is characterized in that the guide plates are provided in a vertical orientation cross-shaped abkragend the post and that increases the length of the guide plates, starting from the base plate upwards. The wind deflecting and deliberately redirecting guide plates of the crosswind baffle element are thus provided projecting in a vertical orientation of the post, so that they form the largest possible attack surface for occurring crosswinds. The length of the guide plates is lower in the lower region and increases towards the top, so that a kind of trapezoidal shape is formed whose width is greater at the top than at the lower end of the crosswind deflection element. All baffles are mounted on a central, uprising post, so that the crosswind baffle can be self-supporting and freestanding without additional anchoring ropes or the like can be mounted. For the installation and installation of the crosswindow element according to the invention, a base-side base plate is provided, on which the central post is fixedly mounted. The baseplate serves to set up and anchor the element in the ground at the point in the terrain where targeted prevention of sedimentation of solids from the air is desired. As a result of the guide plates, which become longer at the top, the crosswind deflector has a surface which is enlarged toward the top and opposes the impinging wind. By this measure according to the invention, the crosswinds are targeted and reinforced intercepted and directed in a kind of nozzle effect with the formation of amplified vertebrae down. These reinforced vortices in the area of the crosswind deflector effectively prevent the deposition of particulate matter from the air, such as sand or snow. If the crosswind baffle element according to the invention is set up at critical points in the mountains, for example at mountain ridges or hilltops, the formation of avalanches due to undesirable local deposits can be prevented with comparatively simple means, since the wind entrained solids do not settle at the points of installation of crosswind deflectors, but are further carried away with the targeted deflected wind. The Seitenwindablenkelement according to the invention thus prevents the formation of undesirable deposits (sedimentation) in open terrain in a relatively simple structural design. This can either be a deposit of shifting sand or a deposit of snow. The crosswind baffle element according to the invention can preferably be set up in groups of several such crossbeam baffles at corresponding problematic terrain sites. Each of the elements is extremely robust due to the central post and can be installed freestanding. The installation and assembly of the crosswind baffles is thereby comparatively simple, since only for the central post a foundation or a counter plate in the field must be prepared in advance.
Nach einer vorteilhaften Ausgestaltung der Erfindung sind die Leitplatten zur Ablenkung der Seitenwinde in festgelegten Abständen zueinander am Pfosten in solch einer Form angeordnet, dass eine Reihe von durchlässigen Zwischenräumen zwischen den Leitplatten gebildet wird. Die durch die Leitplatten gebildeten Windleitelemente des Seitenwindablenkelements sind damit zwar vergleichsweise großflächig vorgesehen, haben jedoch durch die Zwischenräume eine gewisse Durchlässigkeit. Dies hat zum einen den Vorteil, dass die Elemente keine vollflächige Absperrung bilden und ein Hindurchsehen erlauben. Der Eingriff in die Natur ist damit vergleichsweise gering. Zum anderen sind die Elemente durch die Zwischenräume zwischen den Leitplatten weniger anfällig gegen eine Beschädigung durch sehr starke Winde, die insbesondere im Gebirge häufig vorkommen können. Eine langfristige Aufstellung und Stabilität der Elemente ist damit gewährleistet. Nach einem diesbezüglichen vorteilhaften Aspekt können die Zwischenräume insbesondere die Hälfte der Breite der Leitplatten aufweisen, so dass immer noch eine ausreichend große Ablenkfläche für die dort auftreffenden Winde gewährleistet ist, die zu den Verwirbelungen am Boden aufgrund des Düseneffekts führt und eine sichere Verhinderung einer lokalen Sedimentation gewährleistet.According to an advantageous embodiment of the invention, the guide plates for deflecting the crosswinds at fixed distances from one another to the post in such a form that a series of permeable spaces between the guide plates is formed. Although the wind deflectors formed by the baffles of the crosswind baffle element are thus provided comparatively large area, but have a certain permeability through the interstices. On the one hand, this has the advantage that the elements do not form a full-surface barrier and allow a look through. The intervention in nature is thus comparatively small. On the other hand, the elements are less prone to damage by very strong winds through the spaces between the baffles, which can often occur especially in the mountains. A long-term positioning and stability of the elements is guaranteed. According to an advantageous aspect in this respect, the gaps may in particular be half the width of the guide plates, so that a sufficiently large deflection surface is still ensured for the winds impinging there, which leads to the turbulences at the bottom due to the nozzle effect and a reliable prevention of local sedimentation guaranteed.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Leitplatten mindestens an ihren freien Enden derart miteinander gekoppelt, dass sie vier segelartig vom Pfosten kreuzförmig vorstehende Windleitelemente bilden. Die aus Einzelelementen bestehenden Leitplatten sind damit sicher miteinander verbunden und gekoppelt, so dass sie trotz ihrer Durchlässigkeit eine gemeinsame, stabile Komponente für die Zwecke der gezielten Umleitung von Winden bilden. Eine Kopplung der einzelnen Leitplatten kann beispielsweise durch eine starre Verbindung wie ein Verschweißen mit Stäben oder Profilelementen erfolgen. Alternativ kann eine Kopplung auch über flexible Elemente, wie zum Beispiel Drahtseile oder ähnliches, durchgeführt werden. Die miteinander gekoppelten Leitplatten ragen jeweils kreuzförmig von dem zentralen Pfosten vor und bilden eine Art trapezförmiges Segel, mit einer größeren Breite am oberen Ende des Elements als auf Seiten des Bodens.According to a further advantageous embodiment of the invention, the guide plates are at least at their free ends coupled together so that they form four sail-like from the post cross-shaped projecting wind deflectors. From Individual elements existing baffles are thus securely interconnected and coupled so that they form despite their permeability, a common, stable component for the purpose of targeted diversion of winds. A coupling of the individual guide plates can be done for example by a rigid connection such as welding with rods or profile elements. Alternatively, a coupling can also be carried out via flexible elements, such as wire ropes or the like. The coupled baffles each protrude crosswise from the central post and form a kind of trapezoidal sail, with a greater width at the top of the element than on the sides of the bottom.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind kreuzförmig vom Pfosten vorstehende obere und untere Querträger zur Halterung und zusätzlichen Sicherung der Leitplatten vorgesehen. Wenn solche oberen und unteren kreuzförmig vorstehenden Querträger vorhanden sind, können die seitlich vorragenden Leitplatten sicher und fest fixiert werden, ohne dass das Gewicht des gesamten Elements stark erhöht wird. Die Leitplatten können nämlich beispielsweise als sehr dünne Metallbleche vorgesehen werden, die selbst keine große Eigenstabilität aufweisen, jedoch im Zusammenspiel mit den Querträgern, die beispielsweise in Form von Rohrprofilen ausgestaltet sein können, die notwendige Festigkeit gegenüber den auftreffenden Winden auch bei starken Winden aufweisen. Die Halterung und der Einbau der Leitplatten zwischen den Querträgern können dabei auf verschiedene Arten erfolgen: durch feste Verschweißung an Längsstäben, durch Einstecken der Leitplatten in Ausnehmungen, durch Halterung von zwischen den Querträgern aufgespannten Seilen oder ähnliches.According to a further advantageous embodiment of the invention, cross-shaped projecting from the post upper and lower cross member for holding and additional securing the guide plates are provided. With such upper and lower cross-shaped projecting cross beams, the laterally projecting guide plates can be securely and firmly fixed without greatly increasing the weight of the entire member. The baffles can namely be provided, for example, as very thin metal sheets, which themselves have no great intrinsic stability, but in interaction with the cross members, which may be configured for example in the form of tubular profiles, have the necessary strength against the impinging winds even in strong winds. The holder and the installation of the guide plates between the cross members can be done in different ways: by solid welding to longitudinal bars, by inserting the guide plates in recesses, by holding clamped between the cross members cables or the like.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Grundplatte, auf welcher der Pfosten senkrecht aufragend befestigt ist, zweiteilig ausgebildet und mit einer Aufstellhilfe versehen, vorzugsweise vom Typ Rohr-in-Rohr-Stecksystem. Die Grundplatte kann zum Beispiel aus einer ersten Elementplatte und einer zweiten Bodenplatte bestehen, wobei die Elementplatte fest mit dem Pfosten verbunden ist und die Bodenplatte zum Einbau im Erdreich vorgesehen ist. Die Bodenplatte kann aus Metall und/oder einer Kombination aus Metall und einem Betonwerkstoff bestehen, so dass ein sicheres Fundament für das aufzustellende Seitenwindablenkelement gegeben ist. Zum Montieren ist erfindungsgemäß eine Aufstellhilfe beispielsweise nach Art eines Rohrstecksystems vorgesehen: Die Bodenplatte weist hierzu zum Beispiel ein im Durchmesser geringeres Rohr auf, auf welches das im Durchmesser etwas größere Rohr des Pfostens des Seitenwindablenkelements einfach von oben aufgesteckt werden kann. Die Position ist damit schon beim ersten Abstellen des Seitenwindablenkelements sicher fixiert, und eine Montage erfordert nur noch beispielsweise ein Verschrauben der beiden Plattenelemente der Grundplatte miteinander. Dies erleichtert vor allem eine Montage in unwegsamem Gelände über einen Helikopter durch die Luft. Lediglich ein einziger Arbeiter am Boden ist dazu erforderlich. Der notwendige Eingriff in die Natur ist hierdurch außerdem minimal.According to a further advantageous embodiment of the invention, the base plate on which the post is mounted vertically towering, formed in two parts and provided with an erection aid, preferably of the tube-in-tube type plug-in system. The base plate may for example consist of a first element plate and a second bottom plate, wherein the element plate is firmly connected to the post and the bottom plate is provided for installation in the ground. The bottom plate may be made of metal and / or a combination of metal and a concrete material, so that a secure foundation for the deployed crosswind deflector is given. For mounting according to the invention an erection aid, for example, provided in the manner of a pipe plug system: The bottom plate has for this purpose, for example, a smaller diameter pipe on which the slightly larger diameter in the pipe the post of the Seitenwindablenkelements can be simply plugged from above. The position is thus securely fixed already at the first shutdown of the Seitenwindablenkelements, and an assembly requires only, for example, a screwing of the two plate elements of the base plate together. This facilitates above all a mounting in rough terrain via a helicopter through the air. Only a single worker on the ground is required. The necessary intervention in nature is also minimal.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Leitplatten oder die aus den Leitplatten gebildeten vier Windleitelemente mit jeweils oberen und/oder unteren Verstrebungen am oberen und/oder unteren Ende des Pfostens zusätzlich gesichert. Die Verstrebungen können beispielsweise durch schräg von einem freien Ende oder einem mittleren Bereich der Leitplatten bzw. der Querträger zu dem zentralen Pfosten hin verlaufende Seile oder Stangen realisiert sein. Durch solch Verstrebungen wird die Stabilität und Widerstandsfähigkeit gegenüber auftreffenden Winden weiter erhöht. Ohne eine starke Zunahme des Gewichts des Elements kann so ein sehr robuster Aufbau für die Zwecke der Windumleitung erreicht werden. Eine Verstrebung kann zum Beispiel aus gespannten Drahtseilen bestehen, die an Anschlussflanschen befestigt werden. Die Verstrebungen im vorliegenden Zusammenhang können jedoch auch in fester Form, beispielsweise durch angeschweißte Stäbe, ausgeführt sein. Der Vorteil des kompakten und vergleichsweise leichten Aufbaus des Seitenwindablenkelements ist ferner, dass es selbst freistehend im Gelände montiert werden kann, d. h. keine störenden seitlichen Verankerungen durch Drahtseile oder ähnliches erfordert, was mehrere Verankerungspunkte und Betonfundamente oder ähnliches jeweils erfordern würde.According to a further advantageous embodiment of the invention, the guide plates or the four Windleitelemente formed from the guide plates are additionally secured with upper and / or lower struts at the top and / or bottom of the post. The struts can be realized for example by ropes or rods running obliquely from a free end or a central region of the guide plates or the cross member to the central post. Such bracing further increases the stability and resistance to hitting winds. Without a large increase in the weight of the element, a very robust structure for the purpose of wind diversion can be achieved. A strut may for example consist of tensioned wire ropes, which are attached to connecting flanges. However, the struts in the present context may also be in solid form, for example by welded rods executed. The advantage of the compact and comparatively lightweight construction of the crosswind baffle element is further that it can be self-erected in the field, d. H. does not require troublesome lateral anchorages by wire ropes or the like, which would require multiple anchoring points and concrete foundations or the like in each case.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung bestehen die den Wind abfangenden und umleitenden Leitplatten aus in Längsrichtung profilierten oder gerippten Blechen aus einem Metallmaterial. Auf diese Weise können die Leitplatten aus vergleichsweise dünnem Blechmaterial hergestellt werden und sind damit sehr leicht. Dies führt insgesamt zu einer Leichtbaukonstruktion des gesamten Seitenwindablenkelements, was vor allem beim Transport mittels eines Helikopters zur Aufstellung in unwegsamem Gelände von Vorteil ist. Die Leitplatten mit den Profilierungen oder den Verstärkungsrippen in Längsrichtung sind außerdem ausreichend stabil, so dass eine Verbiegung durch starke Winde verhindert werden kann.According to a further advantageous embodiment of the invention consist of the wind catching and diverting guide plates made of profiled or ribbed sheets in the longitudinal direction of a metal material. In this way, the guide plates can be made of comparatively thin sheet material and are therefore very light. This leads to a total lightweight construction of the entire crosswind baffle element, which is especially for transport by means of a helicopter for installation in rough terrain advantage. The guide plates with the profiles or the reinforcing ribs in the longitudinal direction are also sufficiently stable, so that bending by high winds can be prevented.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Leitplatten in einem jeweiligen peripheren Rahmen fest montiert, der seinerseits am Pfosten angebracht ist. Die beispielsweise vier seitlich in einer Kreuzform vorragenden Leitplatten sind somit innerhalb eines Rahmens jeweils fest zusammengebaut und bilden eine kompakte Einheit. Der Rahmen kann aus verschweißten Rohrprofilen bestehen und erhöht die Stabilität und Festigkeit des Elements. Die Leitplatten selbst sind in ihren jeweiligen Rahmen sicher an der gewünschten Position fixiert. Die Montage des Rahmens selbst an dem zentralen Pfosten kann beispielsweise auf lösbare Art und Weise durch Schraubverbindungen mit entsprechenden Flanschen oder ähnlichem erfolgen.According to a further advantageous embodiment of the invention, the guide plates are fixedly mounted in a respective peripheral frame, which in turn is attached to the post. The four, for example, laterally projecting in a cross-shape guide plates are thus each firmly assembled within a frame and form a compact unit. The frame can consist of welded tube profiles and increases the stability and strength of the element. The guide plates themselves are securely fixed in their respective frame at the desired position. The mounting of the frame itself to the central post can for example be done in a detachable manner by screw with corresponding flanges or the like.
Nach einer diesbezüglich alternativen Ausgestaltung der Erfindung sind die jeweiligen Leitplatten einer Gruppe von Leitplatten, die ein gemeinsames Windleitelement bilden, untereinander über Kopplungsseile zwischen oberen und unteren Querträgern verbunden und in ihrer Lage gesichert. Beispielsweise kann am freien Ende der Leitplatten ein erstes Kopplungsseil zwischen einem oberen und unteren Querträger gespannt sein, und es können im mittleren Bereich ein Kopplungsseil oder mehrere Kopplungsseile vorhanden sein, die jeweils die Leitplatten in den vier Richtungen und in der gewünschten vertikalen Ausrichtung halten.According to an alternative embodiment of the invention, the respective guide plates of a group of guide plates, which form a common Windleitelement, connected to each other via coupling cables between the upper and lower cross members and secured in position. For example, at the free end of the guide plates, a first coupling cable between an upper and lower cross member can be stretched, and there may be in the middle region, a coupling cable or more coupling ropes, each holding the guide plates in the four directions and in the desired vertical orientation.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist eine Drehsicherung zur verdrehsicheren Aufstellung des Elements vorgesehen. Eine Drehsicherung kann beispielsweise durch einen Stift oder Schraubbolzen an der Bodenplatte realisiert sein, der in eine entsprechende Bohrung eingreift. Andere Mittel zur Drehsicherung sind ebenfalls denkbar. Die Drehsicherung hat den Vorteil, dass sich das Seitenwindablenkelement je nach Auftreffen der Seitenwinde nicht in der Position verdrehen kann, so dass eine starke Verwirbelung der Seitenwinde und eine gezielte Ableitung nach der Bodenseite immer gewährleistet sind.According to a further advantageous embodiment of the invention, a rotation lock for torsion-proof installation of the element is provided. A rotation lock can be realized for example by a pin or bolt on the bottom plate, which engages in a corresponding hole. Other means for anti-rotation are also conceivable. The anti-rotation device has the advantage that the Seitenwindablenkelement can not rotate in the position depending on the impact of the crosswinds, so that a strong turbulence of the crosswinds and a targeted discharge to the bottom side are always guaranteed.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind Mittel zur Verhinderung eines Drehens des Elements beim Transport mit einem Helikopter oder ähnlichem durch die Luft vorgesehen. Das Seitenwindablenkelement kann somit durch einen Haken von einem Helikopter einfach aufgenommen werden und sicher durch die Luft an die Montagestelle transportiert werden. Auch beim Anheben über einen Kran wird hierdurch ein Verdrehen verhindert. Ein Mittel zur Verhinderung des Drehens des Elements beim Transport in der Luft kann zum Beispiel in Form einer vorragenden Stange mit einem Windsack am freien Ende ausgeführt sein. Die Stange ragt seitlich von dem Seitenwindablenkelement vor und weist an ihrem Ende die Windhose bzw. den Windsack auf, so dass das Element hierdurch in der jeweiligen Lage verbleibt und sich nicht in der Luft drehen kann. Andere Mittel zur Verhinderung eines Drehens des Elements beim Transport durch die Luft können ebenfalls vorgesehen werden.According to a further advantageous embodiment of the invention means are provided for preventing rotation of the element during transport by helicopter or the like through the air. The crosswind deflector can thus be easily picked up by a hook from a helicopter and safely transported through the air to the mounting location. Even when lifting with a crane this prevents twisting. A means for preventing the rotation of the Elements in transit in the air can be designed, for example, in the form of a projecting rod with a windsock at the free end. The rod protrudes laterally from the Seitenwindablenkelement and has at its end the Windhose or windsock, so that the element thereby remains in the respective position and can not rotate in the air. Other means of preventing rotation of the element during airborne transport may also be provided.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Länge der Leitplatten von unten bis nach oben bis auf annähernd das Doppelte vergrößert. Das heißt, die unterste Leitplatte weist in etwa die Hälfte der Länge der obersten Leitplatte auf. Die Fläche für die gezielte Ablenkung der auftreffenden Winde wird somit von unten nach oben relativ stark vergrößert, wodurch eine noch bessere Ablenkung, Umleitung und Verwirbelung aufgrund des erwähnten Düseneffekts mit dem erfindungsgemäßen Seitenwindablenkelement erreicht wird. Eine noch bessere Verhinderung der Ablagerung von Feststoffen im Bereich und im Umkreis der Seitenwindablenkelemente ist damit gewährleistet.According to a further advantageous embodiment of the invention, the length of the guide plates from bottom to top is increased to almost twice. That is, the bottom guide plate is approximately half the length of the top guide plate. The area for the targeted deflection of the impinging winds is thus increased relatively large from bottom to top, whereby an even better deflection, diversion and turbulence due to the aforementioned nozzle effect is achieved with the crosswindow element according to the invention. An even better prevention of the deposition of solids in the area and within the Seitenwindablenkelemente is guaranteed.

In der
Durch die Erfindung wird ein effektives Seitenwindablenkelement 10 bereitgestellt, das eine Ablagerung von Feststoffen aus der Luft an Ort und Stelle direkt aufgrund der Verwirbelung und gezielten Weiterleitung des Windes sicher und großflächig vermeidet. Das erfindungsgemäße Seitenwindablenkelement 10 weist aufgrund seiner Konstruktion mit einer Mehrzahl von vergleichsweise dünnen Leitplatten 3, die kreuzförmig von einem zentralen Pfosten 2 vorragen, ein sehr geringes Gewicht auf, so dass ein Transport mit einem Helikopter ermöglicht wird. Das Gesamtgewicht des Seitenwindablenkelements 10 ist vorzugsweise geringer als 550 kg. Außerdem stellt das erfindungsgemäße Seitenwindablenkelement 10 einen vergleichsweise geringen Eingriff in die Natur dar, da die Elemente nur an bestimmten Punkten jeweils in Gruppen aufgestellt werden müssen und keine großflächigen Baumaßnahmen zur Verhinderung von Schneelawinen, Gerölllawinen oder Ablagerungen von Flugsand erforderlich sind. Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt und kann in verschiedenster Weise modifiziert werden. Insbesondere kann die Form der Leitplatten variieren. Bei den dargestellten Ausführungsbeispielen ist die Länge der untersten Leitplatte 3 im Verhältnis zu der obersten Leitplatte 3 in etwa halb so groß, so dass eine vergleichsweise starke Verbreiterung der Windleitelemente 30 nach oben hin gegeben ist. Alternativ kann die Verbreiterung nach oben hin auch geringer oder stärker ausgebildet sein.The invention provides an effective crosswind baffle element 10 which avoids solids deposits from the air in place, directly and safely, on a large scale due to the turbulence and targeted transmission of the wind. The cross wind deflector 10 according to the invention, due to its construction with a plurality of relatively thin guide plates 3, which project crosswise from a central post 2, a very low weight, so that a transport by helicopter is made possible. The total weight of the crosswind deflector 10 is preferably less than 550 kg. In addition, the cross wind deflector 10 according to the invention represents a relatively minor intervention in nature, since the elements must be placed only at certain points in groups and no large-scale construction measures to prevent snow avalanches, scree avalanches or deposits of blasting sand are required. The invention is not limited to the illustrated embodiments and can be modified in various ways. In particular, the shape of the baffles may vary. In the illustrated embodiments, the length of the bottom guide plate 3 in relation to the top guide plate 3 in about half so large, so that a comparatively strong broadening of the wind deflector 30 is given upwards. Alternatively, the broadening upwards can also be made smaller or stronger.
Die Leitplatten 3 können mit glatten oder profilierten Blechen hergestellt werden, d. h. mit relativ dünnen Blechen, die in Längsrichtung versteifende Verformungen aufweisen. Die Leitplatten 3 können aber auch mit Versteifungsrippen versehen sein, damit die hohe Stabilität trotz der Leichtbauweise gewährleistet ist. Die Leitplatten 3 können auch anders an dem zentralen Pfosten 2 befestigt werden als bei den dargestellten Ausführungsbeispielen mit Kopplungsseilen 9 bzw. einem peripheren Rahmen 8. Beispielsweise können die Leitplatten 3 durch Aufnahmeschlitze in dem Pfosten 2 und ein festes Verschweißen montiert werden. Auch kann der Abstand der Leitplatten 3 zueinander variiert werden, um beispielsweise gezielt eine größere Durchlässigkeit in bestimmten Bereichen zu bewirken: so können beispielsweise die oberen Leitplatten 3 in einem größeren Abstand zueinander als die unteren Leitplatten 3 nahe dem Erdboden montiert sein, um den stärkeren Winden im oberen Bereich Rechnung zu tragen.The guide plates 3 can be made with smooth or profiled sheets, ie with relatively thin sheets, which have stiffening in the longitudinal direction deformations. But the guide plates 3 can also be provided with stiffening ribs, so that the high stability is ensured despite the lightweight construction. The guide plates 3 can also be fixed differently to the central post 2 than in the illustrated embodiments with coupling ropes 9 and a peripheral frame 8, for example. The guide plates 3 can be mounted by receiving slots in the post 2 and a fixed welding. Also, the distance between the guide plates 3 to each other can be varied, for example, to selectively effect a greater permeability in certain areas: for example, the upper guide plates 3 at a greater distance from each other than the lower guide plates 3 be mounted near the ground to account for the stronger winds in the upper area.
