Description

Fastening element for sandwich panels and this containing building envelope

The present invention relates to an elongate fastening element or a system with elongated fastening elements for fastening objects, preferably of solar modules, solar thermal collectors, satellite antennas and other antennas, among others, or for fastening these provided building elements, on building envelopes using a Clamping mechanism.

Sandwich panels with several webs running parallel to one another are known from the prior art. The cross-sectional shape of the webs can vary as desired. The longitudinal joint of two adjacent panels must be permanently sealed against the ingress of rain, wind and snow. In addition, it is necessary for the longitudinal joint with the webs of the panels to have the most uniform possible image. gives.

To this end, Thyssen-Krupp Bausysteme proposes the roof system "Hoesch Isodach Integral", which is shown in FIG

Longitudinal partial webs each with an undercut and an overlap area revealed. In the overlapping area of the panels, a screw is provided which completely penetrates the panels and is screwed into a roof purlin or a building scaffold. In the longitudinal joint between two adjacent panels different seals are introduced. A web, which is formed in the region of the longitudinal joint, is covered with a Fugenabdeckprofil, so that with the other webs of the panels creates a uniform picture.

Furthermore, from the prior art sandwich panels with a plurality of mutually parallel springs (webs) are known, wherein the spring cross-section at least one undercut, preferably a dovetail shape has.

When fastening objects to sandwich panels, usually the roof skin, i. the sandwich panel, penetrated and screwed the object to be fastened with the building envelope. However, there are problems with the sealing in the area of the breakthrough of the building envelope.

For fixing objects to building envelopes with dovetailed, elongated springs different clamping pieces are known from the prior art, to which then the objects to be fastened can be screwed. However, the fastening elements known from the prior art must be positioned exactly at the point at which the element to be fastened is to be positioned during assembly, since a displacement of the fastening element subsequently causes problems due to lack of space during screwing.

The object of the present invention is therefore to provide an elongated fastening element which eliminates the problems described in the prior art, ensures simple assembly and can be produced cost-effectively. In addition, a building envelope with a fastening element and a method for fastening the fastening element as well as the use of the fastening element are to be provided.

The object of the present invention is achieved by the elongate fastening element according to claim 1, the building envelope with fastening element according to claim 13, the method for attaching a fastening element according to claim 15 and the use of the fastening element and the building envelope according to claim 16. Advantageous developments of the present invention are given in the respective subclaims.

The elongated fastening element according to the invention is designed for fastening objects to a panel arrangement, which has an elongated spring with an upper side and two flanks provided with at least one undercut at least on one side thereof. The side, which has the elongated spring can thereby form the building shell or the building inner shell. For the purpose of Fixing of solar cell modules preferably forms the side of the panel, which has the at least one spring, the outer shell of the building.

The described fastening elements are basically also suitable for being fastened to strip pieces which are not located at the joints of sand-weight panels but at other high beads (elongated springs), in particular trapezoidal raised beads of a panel. For example, could be the attachment of such Leistenstücke to or with the screwing of trapezoidal sheets.

According to the invention, the fastening element has at least one strip piece of U-shaped cross-section, a profile strip divided into at least two partial elements in the longitudinal direction of the fastening element, and a connecting device with at least one component.

The U-shaped strip includes two legs substantially parallel to each other and a connecting portion between the legs, the legs being formed on its outside, i. has on its side facing away from the opposite leg, in each case at least one projection (projection) in an area facing away from the connecting portion.

According to the invention, the profiled strip is designed in such a way that it has a covering surface for covering the at least one strip piece and at least for partially covering the elongate spring, a retaining element being arranged on the upper side of the covering surface and two lateral limbs being arranged on the underside of the covering surface. The two lateral limbs point at the femoral interior. Th, ie at the opposite leg facing sides, in each case at least one engagement element. The retaining element on the upper side of the covering surface can be integrated into the profiled strip or can be integrated separately from it into at least one component of the connecting device.

The connecting device is used to connect the at least one strip piece and the profile strip with each other and their connection to the spring of the panel assembly. With the aid of the connecting device, the fastening element can be clamped to the spring in such a way that the connecting section of the strip piece faces away from it with its legs

Side is arranged at least partially substantially centrally directly or indirectly on the top of the spring. In addition, in the mounted (jammed) state, the projection of each groin piece ice engages in the profile strip in the region between the covering surface and the engaging element of the respective adjacent profile piece limb. In other words, the engagement element engages behind the protrusion of the respective neighboring groin limb on the profile limb. In the assembled state continue to engage the legs of the profile strip with its remote from the cover end in the undercuts of the spring of the panel. The legs of the profile strip can either be arranged so that they converge in the direction of their end facing away from the cover surface, or each a projection or a latching projection in the region facing away from the cover ends on its inner side, ie its facing the opposite leg Side, exhibit. Preferably, the at least one strip piece in a groove, which may be formed in the top of the spring, be embedded. This has the advantage that such a slippage of the strip piece on the top of the web can be limited or even prevented.

In the case of an existing puncture of the panels in the region of the top of the web or the groove of the web, this can be exploited to the

To attach strip piece on the top of the bridge. In particular, for the case where the vertical overlap area between two panels (longitudinal joint) has an optionally divided web with undercuts and that the two panels are bolted to each other and to the roof felts in the area of the web, then screwing the groin piece into place by means of the screw used for screwing the panels with the Dachpfetten advantage. Thus forces acting on the fastening element are introduced not only into the panels, but also via the screw into the roof purlin or the roof frame. By such a procedure, the fastener is additionally stabilized.

The fastening element is particularly suitable for springs which are formed along a panel length joint. The fastener not only allows the attachment of objects, but also causes an additional sealing effect and an increase in the stability of the connection between two adjacent panels.

The retaining element is preferably part of the profile strip. In this case, the holding element may be integrally formed with one of the sub-elements of the profile strip or partly in one piece with the one, the other part be formed integrally with the other sub-element of the profile strip. Alternatively, the retaining element can also be formed as a single component separate from the profiled strip or be completely or partially integrated in at least one of the components of the connecting device. The type of formation of the retaining element depends on the embodiment of the connecting device.

The holding element has at least one anchoring possibility for objects. There is the possibility that the elements to be fastened are screwed, jammed, snapped or screwed. For example, there is the possibility that the holding element has two substantially parallel legs, which have projections on their insides. In the space between the legs below the supernatants, a sliding block may be introduced, in which a screw can be screwed or screwed. Alternatively, the legs may also have on their outer side projections in which a clamping element can engage.

As a connecting device, for example, a screw with nut, a mounting clamp or a locking device, preferably a locking profile can be used. The connecting device may be partially or even completely einteilg formed with the profile and / or the Leistenstück. Thus, for example, the profile strip have a threaded bore, so that the connecting device contains only at least one screw and the corresponding counterpart is integrated, for example, in the profile. In the case of a screw connection of the sub-elements of the profiled strip, this is preferably arranged in a region above the covering surface or in a region between the connecting section of the grooved piece and the underside of the covering surface of the profiled strip. The screwing is preferably perpendicular to the longitudinal direction of the fastener. In the case of a mounting clamp, this can encompass the upper region of the profile strip or even the entire profile strip within a longitudinal section. When clamped with the aid of a latching profile, the profile strip advantageously has a counterpart to the latching profile on the upper side of the covering surface or else on a surface arranged above the covering surface.

Preferably, the fastener further comprises anti-slip screws, which establishes a cross-connection between the profiled strip and the strip piece and thus has an additional fastening effect.

The fastener may additionally include at least one seal. This is preferably arranged above the covering surface of the profile strip and is held by projections in the profile strip above the covering surface parallel thereto. Furthermore, seals can also be arranged between the connecting section of the strip piece and the upper side of the spring. Such seals preferably contain or consist of ethylene-propylene-diene rubber or rubber.

Between the strip piece and the top of the spring or the upwardly facing surface within the groove additional profile strips or plates or Be arranged sealing strip. Such profiled strips or platelets or sealing strips can serve the correct positioning of the strip piece o- also restrict or prevent injury to the web when jamming the fastener.

The introduction of sealing strips or sealing rings, in particular in the region of a penetration of the roof skin or in the region of the screwing of the strip piece ensures a watertight seal. The introduction of at least one anti-slip layer between the web top and the strip piece in turn slipping the strip piece is particularly contained during assembly. The profile strip is preferably divided in the region of the cover surface in the longitudinal direction of the fastener into sub-elements. The sub-elements can be formed symmetrically or asymmetrically. The shape depends, inter alia, on the type of connection device and the formation of the holding element.

The sub-elements of the profile strip can preferably be movably connected to each other. Hinges are preferred. A movable connection of the partial elements of the profiled strip is preferably carried out in the area of the covering surface.

The profile strip preferably has a length of at least 70% of the length of the panel and at most 115% of the distance between the roof ridge and the eaves or the height of the building wall. In this case, a panel length of 1 to 25 m, in particular of 6 m or shorter than 6 m is common. The length of the at least one piece of strip may correspond either to the length of the profile strips or to a length in the range of

0.5 cm to 10 cm, preferably in the range of 1 cm to 5 cm, have.

The profiled strip and the strip are preferably extruded and contain one of the materials enumerated in the following or a material mix thereof or consist thereof: metals, in particular aluminum and / or stainless steel and plastic, in particular fiber-reinforced plastics.

The fastening element according to the invention is also particularly suitable for attachment to a web in the region of a panel longitudinal joint of "Hoesch Isodach Integral" panels, as shown in Figure 1. These panels are formed in the region of the longitudinal joint such that the spring is made of at least a first spring member is assembled at the first edge of a first panel and a second spring member at a second, adjacent to the first edge edge of a second panel, wherein the first spring member slowly rises to the first edge, merges into a curved undercut, opens into a curved projection , in a parallel to the base of the panel aligned flat top merges, which at its end facing away from the first edge has a protuberance perpendicular to the flat top, and ends in a further curved projection on the edge, the second spring member slowly rises towards the second edge in a curved undercut passes, rises sharply to a rounded point, drops substantially vertically, into a

Groove merges and terminates in a, over the second edge Ü protruding sheet having a parallel to the panel base surface and a perpendicular formed thereon protuberance, and the protruding sheet of the second spring member, the first spring member in the region of the flat top above- laps and, where appropriate, the two panels in the overlap area are bolted together and with a building scaffolding. On the top of the protruding sheet is an element holder, which is bolted to the two adjacent panels and the roof frame. Such panels, including the elementary holder, have a thickness of from 70 mm to 120 mm, preferably from 75 mm to 115 mm, or exactly 75 mm, 95 mm or 115 mm, the height of the bar including the element holder being approximately 35 mm. The screws for screwing the panels to the building scaffolding are preferably matched to the panel thickness.

The element holder is preferably replaced by a piece Lecks and attached the fastener according to the invention. Alternatively, the strip piece can also be placed on the element holder.

"Hoesch Isodach Integral" describes another system with a web in the region of the length impact, wherein the first spring part slowly rises to the first edge, turns into curved undercut, rises sharply, falls substantially vertically into a first valley, again rises steeply, again falls substantially vertically and ends in an undercut, the second spring part slowly rises towards the second edge, merges into a curved undercut, increases sharply, drops substantially vertically into a second valley, again ascends steeply, drops again substantially vertically, and in a sheet projecting beyond the second edge merges, which has a surface parallel to the panel base and a vertical fold away from the edge, and the protruding sheet of the second bead portion overlaps the first bead portion in the area below the projection of the first bead portion between the first and the second valley is bridged in this embodiment by a U-shaped profile, which is bolted together with the adjacent panels and the Dachpfette. To attach the fastening element according to the invention, a strip piece is preferably screwed in addition to the U-shaped bridge profile and the fastening element is clamped on the web.

A building envelope according to the invention has at least one panel arrangement on the roof or building walls, which has on its one side at least one elongate spring with an upper side and two flanks each providing at least one undercut. On at least one elongate spring is a fastener with at least one strip piece, a longitudinally split profile bar and a connecting device, as already described above, arranged. The fastening element is arranged on the at least one spring so that the connecting portion of the strip piece rests at least partially directly or indirectly on the upper web page. The strip piece is arranged substantially centrally in the transverse direction of the web. In addition, with the aid of the screwing device, the two-part profiled strip is pressed laterally against the web and the groin piece so that the protrusion of each grooved limb engages in an undercut between the covering surface and the at least one engaging element on the inside of each profiled rail limb and that of the covering surface remote from the leg ends of the profile strip engage in the undercut of the web. Building shells with a longitudinal joint design are particularly advantageous, as in the case of the "Hoesch Isodach Integral" roof covering.A spring which extends over the longitudinal joint is composed of at least a first spring part on the first edge of a first panel and a second spring part on a second, the first edge adjacent edge of a second panel, wherein the first spring member slowly rises to the first edge, merges into a curved undercut, opens into a curved projection, merges into a parallel to the base of the panel aligned flat top, which faces away from the first edge end has a protuberance perpendicular to the panel base, and ends in a further curved projection on the edge, the second spring member slowly rises to the second edge, merges into a curved undercut, rises sharply to a rounded tip, substantially perpendicularly drops, merges into a groove and in one, over the second edge protruding sheet ends, which from the

Edge away has a parallel to the panel base surface and a perpendicular formed thereon protuberance, and the supernatant sheet of the second spring member overlaps the first spring member in the area of its flat top side and possibly bolted the two panels in the overlap area with each other and with a plate or a house wall are. Alternatively, the at least a first spring member at the first edge of a first panel and a second spring member at a second edge adjacent to the first edge of a second panel may be composed, wherein the first spring member slowly rises to the first edge, merges into curved undercut strongly rises substantially vertically into a first valley, again rises steeply, again drops substantially vertically and in an undercut fertil, the second spring part slowly rises towards the second edge, merges into a curved undercut, rises sharply, drops substantially vertically into a second valley, again rises steeply, drops again substantially vertically and merges into a sheet projecting beyond the second edge, which has a plane parallel to the panel base surface and a vertical fold away from the edge, and the protruding sheet of the second spring member overlaps the first spring member in the region below the supernatant of the first spring member and possibly the two panels in the overlap area with each other and with a plate or a house wall are bolted. By means of the screw connection in the overlap area of the panels, the strip piece can be screwed to the upper side of the bar and then the fastening element can be connected to the bar.

The arrangement of the fastening element according to the invention on the elongated web in the region of the lengthwise impact has various advantages. By the clamping mechanism, which favors an approximation of the two web edges together, a more stable connection between the two panels is ensured. In addition, an improved seal is provided by the profiled strip, which covers the entire bridge top. If an object is to be fastened to said building envelope, the fastening element according to the invention makes possible an improved holding possibility since the object can be secured by screwing the object

Leistenstücks with the panels and a purlin or building wall is not only attached to the panels themselves, but also attached to the building skeleton.

The fastening element, which is part of the building shell according to the invention, can be designed as desired. taltet, as already described above.

For attaching a fastening element according to the invention to a panel arrangement with at least one elongated spring having an upper side and two flanks provided with at least one undercut, at least one strip piece is initially placed with its connecting section essentially centrally on the upper side of the spring. Preferably, the projections on the legs of the strip protrude the web perpendicular to its longitudinal direction. Subsequently, the sub-elements of the profile strip are applied laterally to the spring and the strip piece, wherein the supernatant of the legs of Leistenstücks lies in the area between the cover surface and engagement element of the respective profile leg and engage the profile strip legs each in undercut of the spring. Finally, the connecting device is mounted so that the sub-elements of the profiled strip are pressed against each other and against the strip piece and the spring.

Before placing the strip piece on the spring, it is possible to apply to the upper side of the spring any spacer, a sealing strip or a sealing disk or else an anti-slip coating. After placing the strip piece on the top of the spring or if the top of the spring has a groove in the region of the groove, the strip piece can e.g. be bolted with a screw with at least one panel and possibly a part of the roof scaffolding.

Depending on the shape of the profile strip, additional components can be introduced between the two subelements of the profile strip, for example additional components. che sealing strip. Depending on the shape of the web cross section, the legs of the profile strip are formed differently. These can be pressed against the covering surface in such a way that they converge in the direction of their ends facing away from the covering surface or that they are bent inwards at their ends facing away from the covering surface or have additional locking projections on their inner sides. Preferably, the legs of the profile strip are formed positively with the web.

The connection of the sub-elements of the profile strip of the at least one strip piece and the spring is preferably carried out by screwing, jamming or latching. In the case of a screw connection, this is preferably perpendicular to the longitudinal direction of the fastener. In the event of jamming with the aid of a clamping element, the clamping mechanism can be triggered either perpendicular to the longitudinal direction or also parallel to the longitudinal direction of the fastening element. If the connection is produced by means of a latching process, the latching element is preferably introduced from a direction perpendicular to the panel base surface.

The fastening element according to the invention and the building envelope according to the invention are preferably used for the fastening of solar modules or of horizontal profiles for solar modules on roofs or building walls. Alternatively, however, various other objects, such as fire ladders, snow guards, flower boxes, various types of rails and the like can be attached. In the event that the side of the panel with the at least one spring forms the building inner shell, for example, shelves, curtains, suspended ceilings, Lam- pen, and the like are attached.

The upper and lower fasteners 30a and 30b contact each other and the upper portion above the legs 35 of the lower fastener 30b partially overlaps the legs 35 of the upper fastener 30a. To prevent slipping, a slip-off screw 50 is inserted in the lower fastening element 30b in the region of the undercut 33 ', which prevents slipping of the two fastening elements 30a and 30b.

The embodiments in FIGS. 3D and 3E can be transferred to all fastening elements according to the invention.

In FIG. 4A, the longitudinal joint between two panels 1 'and 1 "is again provided with partial webs 10' and 10". represented, wherein in the overlapping region of the partial webs 10 'and 10''by means of the screw 7, a strip piece 20 is screwed. Furthermore, the sub-elements 30 'and 30''a profile strip and a locking profile 42 of a fastener according to the invention are shown in the unmounted state. The part below the covering surface 31 of the sub-elements 30 'and 30''is formed as in the previous examples. Above the covering surface 31 at its end, to which also the leg 32 attaches, the holding element 36 sets upwards, which at its upper end in turn has a U-shaped formation 37 with projection. Somewhat spaced apart from the end of the covering surface 31 facing away from the leg 32 is an L-shaped upper part

Bridge 300 protrudes. This has on its the holding element 36 side facing a nose 43a. Between the L-shaped leg 300 and the holding element 36, a projection 301 protrudes on the upper side of the covering surface 31.

The locking profile 42 is U-shaped and has a notch 43b on the insides of its two substantially parallel legs.

For attachment of the individual elements, the sub-elements 30 'and 30' 'in the direction of arrow 0' and 0 '' to the strip piece 20 and the partial webs 10 'and 10' 'applied and the locking profile 42 down over the two L-shaped webs 300th the sub-elements 30 'and 30' 'inverted, so that the projections 43a engages the L-shaped webs 300 in the notches 43b in the substantially parallel legs of the locking profile.

The fastening element is mounted in FIG. 4B State shown. The two sub-elements 30 'and 30''touch each other in the region of the mutually facing ends of the cover surface 31 and the L-shaped leg 300. The L-shaped legs 300 of the sub-elements 30' and 30 '' of the locking profile 42 force and wrapped in a form-fitting manner. Due to the latching of the L-shaped legs 300 with the latching profile 42, the sub-elements 30 'and 30 "are pressed against the partial webs 10' and 10" and the strip 20 such that the protrusions 23 engage in the undercuts 33 ' and that the nose 34 of the legs 32 in the undercut 11 'and 11''of the partial webs 10' and 10 '' engage. The height h between the base surface 1 and the top of the engaging element 33 is also in this case a height of about 35 mm.

FIG. 5A shows a further embodiment of a fastening element according to the invention. In this example, the last piece 20 has projections 23 which extend over approximately 1/3 of the length of the legs 21. The projections 23 are formed such that they widen conically from the upper end of the legs 21 of the strip piece 20 to the outside and protrude in the lower half perpendicular to the side of the legs 21. The sub-elements 30 'and 30''are formed similarly below the cover surface 31 as in the examples before. Only the distance between the cover surface 31 and the engagement member 33 on the leg 32 is larger and corresponds to the extension of the supernatant 23 of the legs 21 of the Leistenstücks. In addition, the leg 32 of the two sub-elements 30 'and 30''each have at least one borehole. The region of the sub-elements 30 'and 30''above the covering surface 31 has only one holding element 36 in the form of a at the top of the cover 31 in the region of the leg extension vertically arranged holding element 36 having a U-shaped design 37 of the upper end. Furthermore, a screw 40 and a nut 41 are shown as a connecting device.

FIG. 5B now shows the fastening element with the components from FIG. 5A in the mounted state. In the process, the partial elements 30 'and 30 "touch on the opposite side of the covering surfaces 31 of the partial elements. The screw 40 penetrates both the sub-elements 30 'and 30' 'in the region between the covering surface 31 and the engaging element 33 of each sub-element 30' and 30 '' and the strip piece 20 in the region of the projections 23. By the screw on the one hand, the supernatant 23 of Leg 21 of the strip piece in the undercut 33 'as well as the nose 34 of the legs 32 of the two sub-elements 30' and 30 '' in the undercuts 11 'and 11' '.

By screwing with the help of the screw 40 and the nut 41, not only the clamping of the fastening element on the partial webs 10 'and 10' 'and on the strip piece 20 is ensured, but also a slip-off due to the cross-gland between the sub-elements 30' and 30 '' with the last piece 20.

The distance h between the base surface 1 and the upper side of the engaging element 33 of the two sub-elements 30 'and 30' 'is again about 35 mm.

FIG. 6A shows two profiled strips, which differ from the profiled strips from FIG. 3A only in the shape of the covering surface 31 and of the leg 38 in FIG the opposite profile strip facing area of the vertical leg 35 differ. The connecting device is integrated in the two profile strips. The right profile strip 30 'has at the level of the cover 31, two parallel arms 310, which each have a locking groove 312 on opposite sides, and at the level of the leg 38 a pin 381, each with a detent 383 on the outer sides. The left profile strip 30 '', however, has at the level of the cover 31 a pin 311, each with a locking lug 313 on the outer sides and at the level of the leg 38 two parallel arms 380, each with a locking groove 382 on opposite sides.

Alternatively, it is also possible that the right or left profile strip 30 'or 30' 'at the level of the cover surface 31 and the leg 38 each have a pin 311 and 381, while the left and the right profile strip 30' 'or 30 'to the corresponding

Each has two parallel arms 310 and 380.

If the profile strips 30 'and 30''in the direction of arrow 0' and 0 '' moved and compressed, the pin 311 between the arms 310 and the pin 381 is inserted between the arms 380 until the respective locking lugs 313 and 383 in the Engage latching grooves 312 and 382 and the two profile strips 30 'and 30''are interconnected. Figure 6B shows the two profile strips 30 'and 30''in the locked state. The arms 310 and 380 are dimensioned with their locking grooves 312 and 382 so that their ends 314 and 384 are in the locked state with the vertical leg 35 in contact. The advantage of such a design is, inter alia, that the connection of the profile strips 30 'and 30'' is distributed over two areas at different heights.

Figure 6C now branches a fastener in the assembled state, wherein the profile strips are formed as shown in Figures 6A and B. The profile strips 30 'and 30' 'are so applied to the partial webs 10' and 10 '' and with the partial webs 10 'and 10' 'screwed piece 20 that the supernatants 23 of the strip piece 20 in the undercuts 33' of the profile strips 30th 'and 30' 'engage and the latching lug 31 of the profile strips 30' and 30 '' in the with the web curb clippings 11 'and 11' hooked. The connection between the profile strips 30 'and 3' 'is made by means of the parallel arms 310 and 380 and the pins 311 and 381. In addition, the connection of the profile strips 30 'and 30' 'can be reinforced by means of a screw 40 and a nut 41 which are arranged in the region of the vertical legs 35 of the profile strips 30' and 30 ''.

In the case of the described embodiment, the longitudinal joints between two fastening elements for left and right profile strip 30 'and 30' 'offset take place. This leads to an improved sealing effect and greater stability.

FIG. 7A now shows a fastening element, wherein a clamping element with a length of approximately 50 mm is used as the connecting device. Again, a strip piece 20 in the transition region between the panels 1 'and 1''screwed to them. The projections 23 of this strip piece 20 taper outward. The partial elements 30 'and 30 "are in the region of a covering surface 31 with a hinge 53 which extends in the longitudinal direction of the fastening element runs, connected. Each subelement 30 'and 30 "below the covering surface 31 has a limb 310 which has an angle of <90 ° with the covering surface 31. At the end of this leg 310, the leg 32 connects with an engagement member 33 and a nose 34 at. The sub-elements 30 'and 30''are folded around the partial webs 10' and 10 '' and the strip piece 20, so that the projections 23 of the strip piece 20 with the sub-elements 30 and 30 'above the engaging member 33 are engaged and that the Nose 34 of the legs 32 in the undercuts 11 'and H''of the partial webs 10' and 10 '' engages. The cover surface 31 of the two sub-elements 30 'and 30 "and the subsequent leg 310, when the sub-elements 30' and 30" are folded around the sub-webs 10 'and 10 ", have the shape of a dovetail. As a connecting device, a clamping device is used in this example. This has a clamping console 44, a clamping piece 45 and an eccentric or a

Screw 46 on. The clamping bracket 44 engages around a first side of the dovetail shape, which is formed by the storage surface 31 and the leg 310, and on the other hand has an undercut into which an upper part 45a of the

Clamping piece 45 can be inserted and fastened by means of the eccentric 46. The lower part 45b of the clamping piece 45 engages around a second side of the dovetail shape of covering surface 31 and leg 310 of the partial element 30 ''. The clamping console 44 has in its upper region a T-shaped leg, which serves as a holding element 36. In the present example, therefore, it is an inventive fastening element, wherein the holding element is not part of the profile strip, but part of the connecting device. FIG. 7B now shows the fastening element according to FIG. 7A in the clamped state. The profile strip clasps non-positively and positively the strip piece 20 and the partial webs 10 'and 10''and the clamping element in turn clasps non-positively the dovetail shape, which is formed by the cover 31 and the legs 310 of the sub-elements 30' and 30 ''.

In Figure 8, in turn, an inventive fastener is shown in the assembled state, wherein as a connecting device again a clamping element with a clamping bracket 44, a clamping piece 45 and an eccentric 46. The strip piece 20 is in turn formed as in Figures 7A and 7B. The sub-elements 30 'and 30' 'of the profile strip have a covering surface 31, which merges into the leg 32 at an angle of> 90 °. The leg 32 has, as in the other embodiments, an engagement member 33 and a nose 34. The sub-elements 30 'and 30' 'are completely surrounded in this embodiment of the lower portion of the clamping bracket 44 and the lower portion of the clamping piece 45. The upper portion 45a of the clamping piece 45 is located within an undercut düng 44a of the clamping bracket 44. With the help of the eccentric 46 clamping piece 45 and clamping bracket 44 can be clamped against each other so that they the sub-elements 30 'and 30' 'and indirectly the sub-webs 10th ' and

10 '' and the bar piece 20 can embrace. In the upper area of the clamping console 44, as in FIGS. 7A and 7B, there is a holding element 36.

FIG. 9 also shows a fastening element according to the invention, wherein again a clamping element with a ner clamping bracket 44, a clamping piece 45 and an eccentric 46 is connected as a connecting device. The strip piece 20 is in turn formed as in Figures 7A and B and Figure 8 and is in the overlap region between the partial webs 10 'and 10''with the panels 1' and 1 '' screwed. The sub-elements 30 'and 30''are formed similarly as shown in Figure 8, wherein the cover surface 31 projects beyond the legs 32. The clamping bracket 44 and the clamping piece 45 are formed in its lower portion so that it engages behind the projecting portion of the cover 31 of the sub-elements 30, and 30 ''. The upper portion of the clamping console 44 in turn has an undercut, within which the upper part 45a of the clamping piece 45 and the eccentric 46 are located and wherein due to the actuation of the eccentric of the clamping mechanism begins.

Also in this embodiment, the clamping bracket 44 has a holding element 36.

In the examples which are shown in FIGS. 7A and B, FIG. 8 and FIG. 9, the clamping mechanism of the clamping element is triggered in each case from a direction parallel to the longitudinal direction of the fastening element. Alternatively, a screw connection of the clamping bracket 44 with the clamping piece 45 perpendicular to the longitudinal direction of the fastening element is possible.

FIG. 10A now shows a detail of a panel arrangement, which are screwed onto two purlins 2a and 2b spaced about 250 cm apart. In the longitudinal joint area (webs 10 'and 10'') of the panels Ia and Ib, which have a width of 1 m, can be seen at the level of the Dachpfetten 2 a and 2 b respectively Screw 7 and the strip piece 20 of a fastener according to the invention.

In Figure 1OB recognizes now again the Dachpfetten 2a and 2b, wherein the screws 7 and the strip pieces 20 of the profile strip 30, which are clamped to the strip piece and the partial webs 10 'and 10' '.

In Figure IOC can now be seen latching connector 61, which are screwed into the profile strip 30 and on which horizontal profiles, in particular horizontal insertion profiles, can be attached.

In FIG. 10D, insertion profiles 62, which are fastened to the latching connectors 61, can now be seen. In the upper area of FIG. 10D, inserted solar modules 63 can be seen.

Figures IIA to HE show the montages of a

Insertion profile 100 on a fastener 30, 30 '. The fastener 30, 30 'corresponds completely to the fastener of Figure 3B, so that the corresponding reference numerals and their explanation for the most part is omitted.

The insert profile 100, in which, for example, solar panels can be inserted, has an undercut groove 101 on its underside. Between the holding element 36 and the insertion profile 100, a cross connector 110 is now arranged as an intermediate fastening element.

This cross connector 110 has a base plate 111, on which a detent 112 is arranged. figure

HC shows a partial element 30 of the fastening element tes, which is already known from Figure 3B.

Figure HD shows the cross connector 100 with its base plate 101. It can be seen that this base plate has a parallelogram shape and in the

Center has an opening 103. FIG. 1 shows the introduction of the cross connector into the undercut groove 101 of the insertion profile. For this purpose, the insertion profile 100 is placed on the cross connector 110 (left side of the figure HE) in longitudinally arranged to the groove base plate 102 and then rotated so that the locking lugs 112 of the cross-connector 110 engage in the undercut of the groove 101.

Furthermore, this connection has a washer 120, which is arranged between the fastening element 30 and the cross connector 110.

For attachment of the insertion profile 100, the cross connector 110 is now first screwed by means of a shim 120, a screw 130 and a screw-in nut 140 in the clamping profile 30. The washer 120 serves to ensure that the cross connector 110 remains rotatable.

Subsequently, therefore, the insert profile 100 is placed over the cross connector HO in the manner shown on the left side of FIG. With an open-end wrench is then the cross connector of the

Side of the insertion profile in the manner shown on the right side of Figure HE twisted and thus the insertion profile 100 is mounted on the clamping profile 110. The cross connector HO engages with the locking lugs or beads 112 provided for this purpose in the corresponding undercuts 101 of the behind cut groove of the insertion profile 100 a.

The attachment of an insertion profile to a fastening element according to the invention, which has been described above with reference to FIGS. IIA to HE, has the advantage that the insertion profiles are fastened in such a way that they do not transmit any forces in the horizontal direction. Such horizontal forces can otherwise damage the basic sandwich panels of the building envelope.

FIGS. 12A to 12E show a further example of such an advantageous fastening of an insert profile 100 on a fastening element according to the invention, which consists of the partial elements 30 and 30 '. Also, this fastener is constructed as the fastener in Figure 3B, but has an additional seal 53 as the fastener in Figure 7A.

In the fastener first two clamping elements 111, 111 'are now arranged, each having on their sides projections which either in the undercut upper mold 36 of the Befestigungsele- elements 30, 30' or on its other side in the undercut groove 101 of the insertion profile 100th intervention.

The clamping profile 111 has a through bore, in which a screw 117, here an internal hexagon (in) screw, is arranged, on which a nut 113 is screwed.

The two mounting brackets 111, 111 'are now introduced into the fastening element 30, 30' and, when the screw 117 is largely unscrewed, into the groove 101 of the insertion profile 100 introduced. By turning the screw 117 by means of an Allen wrench 116, the two mounting brackets 111, 111 'are removed from each other and engage with their noses in the undercut of the groove 101 of the insertion profile 100. As a result, they wedge in the groove 101 (screw) of the insertion profile 100th

FIGS. 13A and 13B show a fastening possibility as shown in FIGS. 12A to 12E, the two mounting brackets 111, 111 'now being rotatably connected to one another by means of a joint 114. When tightening the screw 117, the two upper lugs of the mounting bracket 111, 111 'are now engaged in the undercut of the groove 101 of the insert profile 100 and the two mounting brackets 111, 111' are spread apart.

Both the fastening possibilities illustrated in FIGS. 12A to 12E and those shown in FIGS. 13A and 13B have the advantage that the mounting angles 111, 111 'can be wedged in the screw channel 101 of the insertion profile 100, but the insertion profile 100 in the mounting angles 111, 111 'is freely displaceable.

FIGS. 14A to 14D also show a further fastening possibility, wherein now the clamping angles 111, 111 'are no longer on the side of the engagement in the fastening element 30, 30', but on the side of the engagement in the undercut groove 101 of the insertion profile 100 Joint 114 are pivotally hinged together. Now, the clamping brackets 111, 111 'in turn via a clamping screw 117 and an eccentric on the side of the engagement in the

Undercut 36, 37 of the fastener 30, 30 'spread.

The further embodiment of the embodiment in FIGS. 14A to 14C corresponds to that in FIGS. IIA to HE, 12A to 12E and 13A, 13B.

Also in FIGS. 15 A to E, an attachment possibility of an insertion profile 100 to a fastening element according to the invention is again shown. The insertion profile 100 has again an undercut groove 101 in its lower region, which is formed by two legs 105, each with a nose 106, wherein the lugs 106 protrude in the same direction from the respective legs 105. The insertion profile 100 is anchored to a cross connector 110, which is fastened to the partial elements 30 and 30 'of the profile strip via first and second clamping brackets 107 and 108, which may be formed from bent wire or bent and slotted metal sheet. The cross connector 110 has a

Base plate 111 and two locking lugs 112, wherein the locking lugs 112 are aligned in each case in the same direction. Laterally of the locking lugs 112, in a first and a second clamping strap receiving portion 109, 109 ', the clamping bracket 107 and 108 engage around the base plate 111 and partially the profile strips 30 and 30'. The clamping brackets 107 and 108 engage in the undercut formed by the leg 38 of the profiled strips 30 and 30 '(see Figure 15B).

In the figures 15 C to E, the assembly process of the cross connector 110 and the insert profile 100 is shown. First, the first and the second clamping bracket 107 and 108 are placed over the sub-elements 30 and 30 'of the profile strip. For this purpose, the clamp 107 or 108 either on the front sides over the Moldings 30, 30 'striped or spread by spreading the clamp 107 directly at the installation over the moldings 30, 30' are placed. Subsequently, the cross connector 110 is pushed with its first clamping bracket receiving portion 109 under the first clamp 107 and rotated on the profile strips 30 and 30 '. The clamping bracket receiving area is offset from the axis of rotation of the cross connector 110 such that the cross connector 110 is pressed by the clamping force parallel to the profile strips 30 and 30 '. By hooking the cross connector 110 under the first clamp 107, a high contact pressure of the cross connector 110 on the profile strips 30 and 30 'generated so that slipping of the cross connector 110 along the longitudinal direction of the profile strips 30 and 30' is prevented. This leads to the effect of self-locking.

In this state, the insert profile 100 is placed in the direction of arrow 0 with the legs 105 on the base plate 111 of the cross connector 110 and moved in the direction of arrow 00 on the base plate 111, that the lugs 106 and the locking lugs 112 are engaged with each other.

The slipping up of the insertion profile 100 upwards can be prevented on the one hand by the second clamping strap 108, which is snapped into the second clamping strap receptacle 109 'of the cross connector 110 (see arrow movement 000 in Figure 15E). The achievable clamping forces are lower due to the lack of leverage during assembly. However, the second clamping strap 108 must also essentially prevent only a lifting of the cross connector 110 from the profile strips, the slipping of the cross connector 110 is, as already described, by the clamping force of the first Clamping strap 107 ensured. Alternatively, the second clamp 108 may also be similar to a clamp, as it is known for example of bottle or coffee can closures, be formed.

On the other hand, slipping out of the insertion profile 100 upwards can also or additionally be prevented by means of thin webs 150, 150 ', which are arranged on the insertion profile 100 or on the cross connector 110. These deform elastically upon insertion of the insert profile 100 into the cross connector 110 until the insert profile 100 is in its final position (see FIG. 15E). In this position, the webs snap 150 and 150 'back, thus preventing the insertion profile 100 is pushed back.

In all of these figures, the undercut of the groove 101 of the insert profile in the undercut region on the inside in the longitudinal direction of the profile extending webs / springs 104. The corresponding protrusions 112 of the connecting elements 111, 111 'have corresponding grooves 115 in FIGS. IIA to HE, which lock into the undercut of the groove 101 with the springs 104 after the cross connector 111 has been screwed in, thus ensuring a secure fastening of the insertion profile.
