From the DE 20 2011 104 387 U1 a protective wall is known.

The invention has for its object to further develop the connection concept described there, in particular to improve the connection security in case of occurring lateral load on the protective wall by impact of a vehicle on.

This object is achieved by a protective wall with the features of claim 1.

Advantageous developments of the protective wall according to the invention are the subject of subclaims, the wording of which is hereby incorporated by express reference in the description in order to avoid text repetition.

According to the invention the protective wall is characterized in that the pressure elements are formed as floor panels, wherein the bottom plate of a first protective wall element has at least one projection, which is preferably formed as a trapezoid, most preferably symmetrical trapezoid, square, rectangle, circle segment, triangle, or teeth, and the bottom plate of a second, connected to the first protective wall element protective wall element has at least one complementary to the projection recess, which recess receives the projection in a form-fitting manner.

The protective wall elements themselves can be designed as an open construction in frame construction, preferably made of steel. However, it is also possible an at least partially filled construction in frame construction with a weighting filler, in which filler material may be in particular concrete, plastic, elastomer, wood or a composite in particular of the aforementioned materials.

However, it is also possible to carry out the protective wall elements completely in full-surface volume construction, preferably made of concrete, plastic, elastomer, wood or a composite in particular of the aforementioned materials.

If the protective wall elements are configured in frame construction, longitudinally aligned attachment parts in the form of horizontal struts can be mounted at least partially laterally outside the construction, which are arranged in the transverse direction of the protective wall elements at least partially laterally outside associated vertical struts of the construction. This results in that the protective wall elements in the region of said horizontal struts have their greatest transverse extent, which can prevent an obliquely approaching vehicle from "sticking" to projecting vertical struts of the structure, which can lead to damage to the vehicle.

The said horizontal struts, which are referred to in the context of preferred developments of the protective wall according to the invention as lateral attachments can be rounded or rectangular in cross-section and preferably used in lateral longitudinal recesses of the protective wall elements or laterally mounted on the protective wall elements. In this context, it is possible to form the horizontal struts as solid or hollow profiles. The said horizontal struts or attachments are intended to protect both the approaching vehicle and the protective wall elements themselves from damage.

In the course of yet another development of the protective wall according to the invention can be provided that the protective wall elements have at least one terminal vertical strut with respect to a familiar to the expert planning relevant width of the protective wall elements reduced transverse extent. This aspect also contributes to the proposed protective wall an inclined approaching vehicle opposes the least possible starting resistance.

Another development of the protective wall according to the invention provides that the protective wall elements each have at least one opening in the end faces and / or in the region of the bottom plates. Such a breakthrough is designed such that it cooperates with a corresponding breakthrough of another protective wall element for receiving connecting elements, preferably in the form of bolts.

In addition, it may be provided that said positive connection between adjacent protective wall elements is designed in the manner of at least one pin with complementary pin receptacle or in the manner of a tongue-and-groove connection. Correspondingly, a first protective wall element then has on its end face the pin or the spring, while a second protective wall element, which is connected or to be connected to the first protective wall element, has the pin receptacle or the groove on its end face.

The protective wall elements themselves may be rectangular in cross-section, trapezoidal, rectangular with truncated widened lower mounting area, preferably stepped or formed as modified in the installation area, widened I-profile, without the above list would be conclusive in this regard.

The Applicant has recognized in a variety of practical test procedures in the context of start-up tests that the above-described protective wall with its various developments particularly guaranteed the greatest possible connection security between adjacent protective wall elements. The particular feature of the invention is based on the function and stability at the ends of the protective wall elements and on the connection of such elements to a coherent protective wall system, which can be constructed against lateral, predominantly horizontal load and placed on roads and highways or other areas. On roads and highways this happens mainly in the longitudinal direction with the road as protection against the agreement of vehicles off the road or as separation and protection between traffic flows. The individual protective wall elements have a certain Aufstellbreite and a certain height and a length that corresponds to the actual benefit and function, and in particular based on the dimensions prescribed by the authorities.

A connection of the protective wall elements with each other is ensured by a train, which is advantageously as a horizontal screwing in the longitudinal direction over the ends of two protective wall elements against each other a surface pressure at the ends of the protective wall elements over a full area or a partial area over the system width depending on the requirement for the lateral horizontal pressure load , The width of the pressure surface and the dimension of the train connection establishes the force of the stability of the connection between the protective wall elements. The construction of the individual protective wall elements and the train-pressure connection form a uniform stable protective wall system against lateral horizontal load. Advantageously, said horizontal tension connection is achieved in the longitudinal direction of the protective wall elements via a horizontal, longitudinally arranged screw connection.

The bias of the horizontal, longitudinally-spaced fittings variably allows the creation of a very rigid element connection for straight installation to a relatively "soft" element connection when used for radii configurations, for example in curves. The horizontal gland may include one or more glands per element connection.

A particularly preferred embodiment of the protective wall element according to the invention provides that a dimension of the protective wall element in the longitudinal direction, ie in the direction of its longitudinal extent is about 6,000 mm, preferably about 6,000 ± 50 mm. It has been shown in practice that the profiles, tubes and sheets used in the manufacture of the protective wall elements as steel structures or as combined steel / concrete structures in commercial lengths of 6,000 and 12,000 mm long. As part of The described development of the invention can be used as a cost-effective availability.

Furthermore, the processing of lengths of 6,000 mm as a length measure and a length weight is advantageous for the work processes, processing and manpower. Subsequent refining of the metals used, e.g. by hot-dip galvanizing, also corresponds to the most favorable and best manufacturing requirements of the length of 6,000 mm.

For concreting or generally pouring with a casting material formwork and forms are also used in these lengths with profiles and sheets in commercial quantities.

The protective walls described above can be used in particular for temporary use on roads, highways and other parking areas. The use takes place over the typical service life several hundred times, so that it is accordingly important to provide lengths, weights and volumes that are particularly favorable for transport, installation and storage. With an element length of in particular 6,000 mm, due to the element volume as a long, narrow, upright steel construction made of profiles or as steel / concrete construction made of profiles with concrete, a low weight in relation to the volume results. The weight is essential for transport and assembly, ie for the load on normal transport vehicles. The same applies to the transport quantity and the hoists used, i. Crane systems on vehicles. Depending on the design, the element weights at 6,000 mm in length are between 200 kg and 900 kg.

Particularly suitable is the desired element length of 6,000 mm with respect to the loading lengths of the transport vehicles used, e.g. Building material vehicles as tractors with a loading area of approx. 6.20 to 6.70 m, possibly with a trailer (loading length approx. 6.20 to 7.0 m). A truck with semi-trailer has a loading length of approx. 12.50 to 13.40 m. Thus, the loading lengths of the normally available vehicles can be optimally used.

The assembly and disassembly of the 6,000 mm long elements is in combination with transport vehicles, crane, hoist and element weights one optimized use of all normally available resources that must be available for special use on roads and highways in the shortest possible time.

A preferred embodiment of the present invention accordingly provides a protective wall system consisting of individual elements (protective wall elements) which are set up in the longitudinal direction on the wall element ends (front sides) of a plurality of elements in a longitudinal position on the bottom on one or more installation surfaces. The aforementioned mounting surfaces are formed in particular by the pressure plates described above, but other elements (protective or damping elements) may be attached to their undersides.

Preferred embodiments of the invention provide that the protective wall elements have a frame construction made of steel and are supplemented to increase the weight with concrete, recycled plastic or other weighting elements. At the element ends vertical faces with horizontal screwing two element ends together in the longitudinal direction as a tension and pressure system for a very stable element connection against lateral, horizontal load.

In a preferred embodiment, the protective wall elements consist of longitudinally horizontally arranged profiles, tubes or sheets, which can be fastened laterally between the end faces of the element ends. In this way one or more profiles may be provided over the length of the element. The superimposed on both sides of the protective wall elements and / or in the vertical direction profiles, tubes or sheets provide a stabilizing function against lateral, horizontal load or against from above acting vertical load.

As a preferred material for the described frame construction steel is used. This can be hot dip galvanized or protected by paint / coating against corrosion.

The construction described profile, tubes and sheets may have cavities, which at least partially with concrete for additional weight increase or another casting material. The concrete filling is integrated into the construction for an intimate connection with the stabilizing profiles, pipes or sheets by means of gears, reinforcements or the like, which is known in principle to the person skilled in the art.

With the achievable profiled construction the required stability for the purpose is achieved. The supplementary concrete filling or the like is used to increase the weight and can additionally ensure stability. In the course of a preferred embodiment of the invention, it is provided that the concrete filling or the like occupies a maximum of 50% of the system volume of the individual protective wall elements. Preferably, the concrete portion (the casting material) is introduced in the lower part of the protective wall elements and extending in the longitudinal direction.

FIG. 1 shows in the left part of the figure in plan view a protective wall according to the invention, which is designated in its entirety by the reference numeral 1 and formed in the direction of its longitudinal extent L successively arranged and frontally interconnected protective wall elements 2, which Protective wall elements 2 in FIG. 1 are shown schematically in dashed form. The protective wall 1 serves to an approaching motor vehicle, which in FIG. 1 is shown at reference numeral 3, stop, so that this particular does not depend on the road, for example, on the opposite lane. This effect of the protective wall 1 is in the right part of FIG. 1 shown. In this context, the abbreviation BS stands for the structural width of the protective wall 1, the abbreviation DD denotes the so-called dynamic deflection when starting by means of the motor vehicle 3 and the abbreviation WB denotes the actual effective range of the protective wall 1. As shown in the right part of FIG. 1 WB = BS + DD.

To produce the protective wall 1 according to the invention, the protective wall elements 2 - as already stated - frontally connected in pairs, the connection in the direction of the longitudinal extent L of both the protective wall 1 and the individual protective wall elements 2 under train, which will be discussed in more detail below.

FIG. 2 shows an example of a possible protective wall element 2 to create a protective wall according to the invention, wherein the protective wall element 2 according to FIG. 2 is designed as an open construction in frame construction, preferably in steel. The protective wall element 2 comprises terminal vertical struts 2a, whose specific embodiment will be discussed in more detail below. Between the terminal vertical struts 2a further vertical struts or posts 2b are arranged. The said vertical struts 2a, 2b are connected in the upper region of the protective wall element 2 by means of an upper horizontal profile or an upper horizontal strut 2c, which is approximately C-shaped in cross-section. At the middle level of the protective wall element 2, the said vertical struts 2a, 2b are connected on both sides of the protective wall element 2 by means of a further lateral horizontal strut or a lateral horizontal profile 2d, of which FIG FIG. 2 due to the selected representation, only one or one recognizable. The lateral horizontal strut 2d is executed in cross-section approximately U-shaped. In the lower region of the protective wall element 2, this has on each side an outwardly angled, continuous L-profile 2e, whose outwardly angled leg 2f extends approximately parallel to an imaginary mounting surface for the protective wall element 2. The two L-profiles 2e are at least in the area of the vertical struts 2a, b interconnected by horizontal web plates 2g, 2h. In the region of at least the inner vertical struts 2 b and the outer legs 2 f of the L-profiles 2 e, the protective wall element 2 a plurality of reflector elements 2 i, 2 j, of which in FIG. 2 for reasons of clarity, only a few are explicitly designated. On the particular embodiment of the protective wall element 2 in the region of the terminal vertical struts 2a is now based on FIG. 3 discussed in more detail.

FIG. 3 shows two protective wall elements 2 in their mutual connection area in the still unconnected state. Here, as in all other figures, like reference numerals designate the same or equivalent elements.

The two to be connected protective wall elements 2 are placed in the region of their terminal vertical struts 2a on the end faces 2aa abutting each other and braced by bolts 2k in the longitudinal direction against each other, the bolts 2k are inserted through aligned openings 2ab in the vertical struts 2a inserted and secured by nuts 2l. In the region of its upper side, the terminal vertical struts 2a have a groove 2ac extending in the longitudinal direction of the protective wall elements 2, which groove extends below the upper horizontal strut or the upper horizontal profile 2c. In this groove, an elongated cuboid connection / locking element 2m can be introduced and positively received therein, which locking element 2m is an optional part of the protective wall according to the invention.

Between the terminal vertical struts 2 a and the terminal web surfaces 2 g, lateral, triangular reinforcing elements 2 n are welded in order to increase the stability of the protective wall elements 2.

The terminal vertical struts 2a have their largest dimensions transversely to the longitudinal extension of the protective wall elements 2 in those areas in which they are laterally surrounded by the horizontal struts 2c, 2d and the lower lateral L-profiles 2e. In the intervening areas where according to FIG. 3 the openings 2ab are, the vertical struts 2a each have a smaller transverse extent. In this way, it is ensured that a vehicle approaching the protective wall (cf. FIG. 1 ) Not in the connecting region of two protective wall elements 2 on transverse projections of the same and in particular not on transverse projections of the vertical connecting struts 2a "stuck", which has otherwise regularly led in practice to damage the tires of the vehicle.

An essential part of the connection to be created between the protective wall elements 2 according to FIG FIG. 3 is produced in the respective lower part of the protective wall elements 2. This will now be discussed in more detail below.

In the lower region of their end faces or the adjacent regions, the protective wall elements 2 have pressure elements in the form of bottom or pressure plates 2p, 2p ', to which reference is also made below FIG. 5 will be discussed in more detail. The pressure plates 2p, 2p 'have in pairs between two protective wall elements 2 to be connected in their mutually facing areas complementary shapes, so that they interact positively when connecting the protective wall elements 2 with each other. Together with the Längsverschraubung 2k, 2l of the protective wall elements 2 results from the interaction of the pressure plates 2p, 2p 'a so-called train-pressure shock, which ensures an optimal connection between the protective wall elements 2.

Below the pressure plates 2p, 2p 'are still plate or mat-shaped damping elements 2q arranged, which are preferably formed in a suitable rubber or plastic material.

As in the left part of the FIG. 3 indicated, the pressure plate 2p may protrude slightly forward over the end face 2aa of the terminal vertical brace 2a of the protective wall element 2. This can favor the formation of said train-pressure shock.

FIG. 4 shows the protective wall elements 2 according to FIG. 3 after completion of the connection by tightening the bolt 2k for producing the pressure shock in the region of the pressure plates 2p, 2p '.

FIG. 5 shows again in detail and in plan view, the two printing plates according to FIG. 3 respectively. FIG. 4 , Clearly visible is the complementary form-fitting design of the printing plates 2p, 2p 'in the area of each other in Interacting passing sides or side surfaces. While one pressure plate 2p has a projection 2pa in the manner of a symmetrical trapezoid, the other pressure plate 2p 'has a corresponding complementarily shaped recess 2pa'. In order to favorably influence mechanical stresses, one pressure plate 2p in the connection region of the projection 2pa has notches 2pb on the remaining plate. The same applies to the other pressure plate 2p 'in the region of the bends of the recessed portion 2pa', wherein the notches are designated here by the reference numeral 2pb '.

Figures 6a-6e show the embodiment of the FIG. 5 alternative embodiments of the printing plates 2p and 2p '. The printing plates 2p in the right part of the Figures 6a-6e each have at least one projection 2pa, while the pressure plates 2p 'in the left part of Figures 6a-6e each having a corresponding number of complementary trained recesses 2pa '.

According to FIG. 6a are projection 2pa and recess 2pa 'formed substantially square. According to FIG. 6b a plurality of such square projections 2pa or recesses 2pa 'are provided. The printing plates 2p, 2p 'according to FIG. 6c have a semicircular projection 2pa or a semicircular recess 2pa 'on. The embodiment according to FIG. 6d is essentially the same as FIG. 5 , but omitted the said notches and a relatively wider trapezoidal shape was selected. According to the embodiment in FIG. 6e For example, the pressure plate 2p has three substantially triangular serrations or points which can engage or engage in correspondingly complementary recesses 2pa 'of the second pressure plate 2p'.

FIGS. 7a to 7c clarify possible arrangements of the printing plates 2p and 2p 'with respect to the rest of the protective wall elements 2, as indicated above with reference to FIG. 3 has already been pointed out.

According to Figure 7a Collar both the left pressure plate 2p 'and the right pressure plate 2p against the respective end faces 2aa of the protective wall elements 2 before. According to FIG. 7b close both pressure plates 2p, 2p 'with their facing front sides flush with the end faces 2aa of the protective wall elements 2 from. As shown in FIG. 7c she jumps a pressure plate 2p with respect to the front side surface 2aa of the respective protective wall element 2, while the other pressure plate 2p 'is set back relative to the front side surface 2aa of the respective protective wall element 2, so that the pressure plate 2p in connecting the protective wall elements 2 according to FIG FIG. 7c the corresponding other protective wall element 2 engages under the connection area.

In FIG. 8 not inventive protective wall elements are shown in which the pressure plates or pressure elements are not arranged parallel to a footprint of the protective wall elements 2, but perpendicular thereto, and that parallel to the end faces 2aa of the protective wall elements 2, as in FIG. 8 shown. For distinction from the printing plates 2p, 2p 'according to the FIGS. 3 to 7 are the printing plates or printing elements according to FIG. 8 denoted by the reference numeral 2r and 2r '.

The rest of the design of the protective wall elements 2 is otherwise preferably according to the FIGS. 3 and 4 , so that it is not otherwise discussed here.

As the person skilled in the art recognizes, in the region of the base-side installation surface of the protective wall elements 2 according to FIG FIG. 20a until i still printing plates of the type described above (horizontal and / or vertical) to be supplemented.

The embodiment according to the invention FIG. 21 was fundamentally above on the basis of FIG. 13c or alternatively FIG. 16a already described. In addition to the side view according to FIG. 21 However, let me now still on the top view according to the Figures 22a and 22b indicated, again reference numerals x as in FIG. 12a and FIG. 12b designates the Aufstellbreite. In addition, referred to in the Figures 21, 22a and 22b the reference SF the butt joint between the pressure plates 2p, 2p '.

In FIG. 22a an embodiment is shown in which said bottom plates 2p, 2p 'below the lateral L-profiles 2e (see. FIG. 3 ) are arranged. This is in FIG. 22a symbolized by dashed boundary lines for the plates 2p, 2p '.

In the embodiment according to FIG. 22b The lateral L-profiles are dispensed with, and the bottom plates 2p, 2p ', which are arranged below the actual wall body of the protective wall elements 2 and project over the end faces 2aa, are clearly visible in plan view.

The FIGS. 23a to 23g show the connection situation in two protective wall elements 2 with each terminal projecting pressure plates 2p, which in particular according to the Figures 5 or 6 can be trained. Figures 23a, c and e each show a side view, whereas the FIGS. 23b, d and f Frontal views in the area of the front side surfaces show (see. Figures 11h, f and b ).

Figure 23g shows a corresponding plan view, in particular according to Figures 23c and e.

The Figures 24a to 24g show corresponding figures for embodiments with (additional) vertical pressure plate 2r, cf. FIG. 8 , In the embodiment according to the invention according to the FIGS. 24e and f comes have the vertical pressure plate 2r still a bottom-side pressure plate 2p used.

The Figures 25a and 25b show in plan view (top) and in side view (bottom) two protective wall elements 2 with bottom side arranged pressure plates 2p, wherein according to FIG. 25a the printing plates 2p are substantially flush with the end faces 2aa of the protective wall elements, while according to FIG. 25b the left pressure plate 2p protrudes clearly beyond the end face 2aa of the respective protective wall element, while the other pressure plate 2b is set back relative to the end face 2aa of the relevant protective wall element (cf. FIGS. 7b and 7c ).

The protective wall elements 2 each have in the left part of Figure 25a, 25b a central recess 2x on, while in the FIGS. 25a and b right shown protective wall elements 2 have a complementary central projection 2y. The corresponding apertures for inserting the tension-connection means are in the region of the recess 2x and the projection 2y, which in FIG. 25 represented by short, horizontal lines only symbolically.

Notwithstanding the embodiment described above, it is also possible to design the protective wall elements 2 as substantially plate-shaped wall body elements with a rectangular cross-section, which are widened laterally in the lower-side installation area, such as in FIG. 3 shown, cf. the lateral L-profiles 2e.

In a corresponding modification of FIG. 25a Then, the right protective wall element 2 is introduced with its projection 2y in the exception area 2x between the two L-profiles, which is completed by the pressure plate 2p down. The same applies to the embodiment according to FIG. 25b , here still the left protective wall element 2 engages with its projecting pressure plate 2p in the area below the right protective wall element 2 until touch the two pressure plates 2b with their front edges in the pressure surge.

FIG. 26 It is essential that the protective wall element 2 in turn has a steel frame construction, which is only in the lower region of the protective wall element with concrete BE or another suitable (cast) material, eg (recycled). ) Plastic, reinforced or weighted. The remaining components of the protective wall element 2 according to FIG. 26 , denoted there by reference ST, are formed in steel. Otherwise corresponds to the protective wall element 2 according to FIG. 26 essentially according to the embodiment FIG. 3 ,

In the area of the concrete mass BE, recesses or openings are provided at reference signs 2t in order to reach the openings 2ab arranged in this area for the screwing means (not shown), as described above with reference to FIG FIGS. 13a-c described in detail.

FIGS. 27a and b show a non-inventive protective wall element 2, which also substantially the embodiment already described in detail in FIG. 3 corresponds, so that in the present case only a few peculiarities have to be addressed. As is specific from the frontal view according to Figure 27b results, the protective wall element 2 in the region of the bottom-side pressure plate 2p an overall width B, while the width b in the upper region of the protective wall (upper horizontal strut or upper horizontal profile 2c) fails lower. Without limitation, B may be between 240 and 300 mm while b may be about 100 to 120 mm.

As it turned out Figure 27b results still, runs outwardly angled leg 2f of the lower side L-profiles 2e at an angle α obliquely with respect to the top of the pressure plate 2p, where α is in the range between 0 and 5 °. The outwardly angled leg 2f forms here - as well as in the correspondingly equipped, previously described embodiments an approach surface for the protective wall or the protective wall element 2 approaching vehicle, so that the vehicle provides with its weight for stabilizing the protective wall against lateral tipping ,

The Figures 28a and b show a modification of the non-inventive protective wall element 2 according to Figure 27a, b again focusing only on the essential differences.

As already in FIG. 26 reference symbol BE denotes concrete or another casting material which is used to weight the protective wall element 2, which is otherwise made of steel frame construction.

A difference from the previously explained embodiments of the protective wall element 2 is that the lower longitudinal profile elements 2 e are not formed as an L-profile, but in the pointed angled shape shown. The angle α between the upper, outwardly facing leg 2f of the profile elements 2e and the horizontal or an imaginary plane footprint for the protective wall element 2 is a maximum of 45 °. In this way, the leg 2f again acts as a driving surface for a vehicle approaching the protective wall. The defined between the longitudinal profile elements 2e in the embodiment shown inner space is with the already mentioned casting compound or concrete BE filled. The other, lower leg 2f 'of the longitudinal profile elements 2e in turn is oriented approximately horizontally and allows a surface connection to the pressure plate 2p arranged underneath.

The non-inventive embodiment according to the FIGS. 29a and b is basically the same as in Figure 27a , b. Deviating, however, in the lower region of the protective wall element 2, above the pressure plate 2p, a single, continuous longitudinal profile 2e provided in the form of a hollow profile with a rectangular cross-section, on the upper side of the terminal vertical brace 2a of the protective wall element 2 is placed and secured cohesively.

As the skilled person realizes, it is also possible in this embodiment, at least partially fill the existing in the lower hollow profile 2e clearance with a weighting material (not shown) and / or the said space on the joint of two protective wall elements 2 away for insertion of one of the two protective wall elements connecting element (see element 2m in FIG. 3 ).

The non-inventive embodiments according to the FIGS. 30a, b show a modification of the embodiment according to particular Figure 27a , b. This relates first of all to the profiling of the horizontal struts 2d, which have only one simple bend (compare the double bend (trapezoidal shape) according to FIG Figure 27a, b ). Correspondingly, the cross-section of the terminal vertical struts 2a widens in the connection region with the said horizontal struts 2d and then remains downwards, ie, constant except for the pressure plate 2p. In the region defined between the vertically rising legs of the L-profiles 2e and the horizontal struts 2d there is in turn a weighting element or weighting material BE, for example a cast body made of concrete, plastic or another suitable material.

The non-inventive embodiments according to the Figures 31a to c show a further, modified embodiment of the protective wall element 2. This corresponds initially, based on the profiling, basically the protective wall element according to Figure 27a , b. However, the vertical end brace 2a deviating without special profiling, ie rectangular in cross-section, and instead of the upper C-profile come two laterally attached U-profiles 2c 'used as upper horizontal struts. For the lower profile element 2e is formed as a simple, approximately in cross-section C-shaped profile element, and touched with its middle leg, the pressure plate 2p, while the terminal vertical strut 2a and further vertical struts 2b protrude upwards from the C-profile element 2e, as shown. At reference numeral BE in Figure 31c, a plate-shaped weighting element, for example made of concrete, plastic, metal or the like is shown, which has an actual plate body BEK, which is provided with a handle element BEG. The dimensions of the weighting element BE are selected so that it is shown in arrow PB in FIG FIG. 31a can be inserted from above between the profiles 2c 'in the frame construction of the protective wall element 2, to complain the protective wall element 2. As those skilled in the art will recognize, the weighting element BE is according to FIG. 31c In particular, during disassembly of the protective wall element 2 also readily apparent from this again.

The non-inventive embodiments according to the FIGS. 32a, b show a modification of the protective wall element 2 according to the FIGS. 30a , b. As in the previously described embodiments, the actual frame construction consists of steel (ST) and receives a weighting element BE, which is formed, for example, in concrete or another casting material. Otherwise, the embodiment differs according to the FIGS. 32a, b from the one in FIG. 30a, b essentially by the rounded in the bending area configuration of the longitudinal profiles 2c, 2d. In this case, instead of two separate longitudinal profiles or horizontal struts 2d (see. FIG. 30a ) according to FIG. 32a only a single longitudinal profile be provided, which is U-shaped in cross-section and the function of the two longitudinal profiles or horizontal struts 2d according to FIG. 30a summarizes.

The same applies essentially to the non-inventive embodiments according to the FIGS. 33a, b and 34a, b , In both cases, the cross section of the end vertical strut 2 a widens downward, in the case of FIGS. 33a, b only in the lower area and in the case of FIGS. 34a, b continuously starting from the middle horizontal strut 2d. Accordingly, the lower side L-side profiles 2e have an obtuse angle between their two legs.

Vertical strut 2a downwards, in the case of FIGS. 33a, b only in the lower area and in the case of FIGS. 34a, b continuously starting from the middle horizontal strut 2d. Accordingly, the lower side L-side profiles 2e have an obtuse angle between their two legs.
