FIG. 1 shows a protective wall according to the invention 38, which is formed of a plurality of interconnected protective wall elements 17, of which in FIG. 1 only two are shown as examples. The protective wall elements 17 are set up to create the protective wall 38 on a substrate 3 and in the area the end faces 19, 20 of their respective wall body or wall body elements 18 are connected together in a connecting region VB. The connection takes place by means of tensioning / connecting means 39 arranged or effective in the longitudinal direction of the protective wall 38, which can be designed in particular, but without limitation, as a threaded bolt. The clamping / connecting means 39 may be arranged relative to the substrate 3 in the upper and / or middle and / or lower region of the protective wall elements 17. The clamping / connecting means 39 may also be arranged centrally and / or eccentrically relative to a vertical central axis (not explicitly designated) of the protective wall elements 17.

According to the embodiment in FIG. 1 touch the protective wall elements 17 with their smooth, in the erected state substantially perpendicular to the substrate 3 oriented end faces 19, 20 to create the said compound area and immediately. The already mentioned clamping / connecting means 39 provide a non-positive connection and act as part of a releasably adjustable drawstring, which clamped in the protective wall elements 17 in the longitudinal direction to create the protective wall 38 against each other. On the arrangement of the clamping / connecting means 39 will be described below in particular with reference to FIG. 3 discussed in more detail.

The protective wall elements 17 according to FIG. 1 are characterized by a so-called open design and have - in the manner of a fence - horizontal struts 17a-c, which are oriented in the longitudinal direction of the protective wall 38. These horizontal struts 17a-c are also indicated by the illustration in FIG FIG. 3 good to take. In particular, some of the said horizontal struts 17a, 17b may be U-shaped in cross-section and oriented differently within the respective protective wall element 17. In its lower region facing or facing the substrate 3, the protective wall element 17 has a cross-sectional widening 17d, whereby on the underside of the protective wall element 17 a flat mounting surface laterally widened relative to the wall body 18 is formed, which forms an integral unit with the remaining protective wall element 17.

Furthermore, the FIG. 3 to take a vertical strut 17e of the described protective wall element 17, which the already mentioned horizontal struts 17a-c fence or gate-like connects. Such vertical struts 17e can be found in preferably regular intervals in the direction of the longitudinal extension of the protective wall element 17 FIG. 1 and FIG. 3 ,

At the end faces 19, 20 are each plate-shaped, flat termination elements 19 ', 20' are arranged, via which the individual protective wall elements 17 abut each other. As shown in FIG. 3 these termination elements 19 ', 20' between different protective wall elements 17 aligned connecting structures in the form of openings 23, which serve to receive the already mentioned clamping and connecting means 39.

The protective wall 38 or the protective wall element 17 according to FIG. 2 differs from the previously discussed embodiment according to the FIGS. 1 and 3 The latter are preferably made of a steel construction which is filled with a hardenable casting material, such as concrete, with internal reinforcement 42. It is also possible to use fiber concrete (fiber reinforced concrete) to obtain improved elasticity. For introducing the clamping / connecting means 39 recesses 26 d are provided in the wall body elements 18, as shown in the drawing. Otherwise, the design and function of the protective walls 38 are in accordance with the Figures 1 and 2 much as possible.

On the other hand illustrate the FIGS. 4 and 5 a different connection concept to provide another embodiment of the protective wall 38 of the invention without this would be at this point to go into more detail in this respect, should FIG. 4 again represent the open construction, while FIG. 5 illustrating the closed construction.

As in the FIGS. 4 and 5 each shown in dashed lines, in each case a vertical connecting element 6 is present in the connection region VB, which is inserted in the connection region VB between the protective wall elements 17 to be connected and which is penetrated corresponding to the connecting the protective wall elements 17 of the clamping / connecting means 39. In the area of the end faces 19, 20, the protective wall elements 17 are suitable Structures for receiving the vertical connecting element 6, which will be discussed in more detail below.

Moreover, in the embodiments according to the FIGS. 4 and 5 another - also shown in dashed lines - horizontal connecting element 7, 8 is present, which is arranged in the lower region of the protective wall elements 17. The protective wall elements 17 have accordingly on their underside suitable structures for receiving the horizontal connecting element 7, 8, which will also be discussed in more detail below.

The horizontal connecting element 7, 8 may be formed in the longitudinal direction of the protective wall 38 substantially continuously through. However, it is also possible to design the horizontal connecting element 7, 8 in the form of shorter sections, which in particular can correspond exactly to the dimension of a single protective wall element 17 in the longitudinal direction. However, even shorter embodiments of the horizontal connecting element 7, 8 are possible, for example, corresponding to half the longitudinal extent of a single protective wall element 17 or even shorter. Also, two horizontal connecting elements 7, 8 can be combined with a vertical connecting element 6 in the form of a substantially T-shaped installation and connecting device for protective wall elements, which will be discussed in more detail below.

According to the FIGS. 4 and 5 Thus, the connection of the individual protective wall elements 17 to a protective wall 38 according to the invention does not take place directly, as in the Figures 1 and 2 but indirectly via "interposition" of at least the vertical connecting element 6. Advantageously, in this context, the aforementioned horizontal connecting elements 7, 8 are available, but it would also be the creation of a protective wall 38 possible, which basically without the horizontal connecting elements 7, 8 manages.

Thus, according to the FIGS. 1 to 5 the two basic types of construction of the protective wall 38 according to the invention have been conceptually explained, will now be described with reference to the FIGS. 6 to 9 on constructive details of those Protective wall elements 17 received in more detail, which in a protective wall according to the FIGS. 1 and 3 preferably used.

FIG. 6 shows with reference to a perspective detail view again in more detail an embodiment of the protective wall element 17 according to FIG. 3 , It is at this point only to those constructive features of the protective wall element 17 according to FIG. 6 more detail in the FIGS. 1 and 3 not shown or were not recognizable.

This initially relates to reflector elements 28, 29, which can be arranged laterally in the region of the cross-sectional widening 17d on the upper side or on the horizontal struts 17a, 17b.

In addition, the protective wall element 17 according to FIG. 6 in each case a recess 19 ", 20" with a rectangular cross-section, which serves for the substantially positive reception of a profile element 46, which profile element 46 for the first time in. In each upper end of the end faces 19, 20 and the respective closing elements 19 ', 20' FIG. 8 is shown. The relative dimensions of the profile element 46 and the recesses 19 ", 20" are selected such that the profile element 46 protrudes from the relevant protective wall element in the received state to connect the protective wall element 17 by engaging in the corresponding recess of an adjacent protective wall element with the adjacent protective wall element , This increases the transverse stability of the created protective wall. Preferably, apart from the positive reception in the recesses 19 ", 20" no further fixation of the profile element 46, which facilitates the construction of the protective wall.

Furthermore, in FIG. 6 nor shown that the protective wall element 17 in the region of said cross-sectional enlargement 17 d on its underside 25 has two flat, spaced apart in the transverse direction of the protective wall element 17 Aufstellflächenelemente 47. These Aufstellflächenelemente 47 are preferably made of a suitable material with a material thickness of at least 10 mm and facilitate the one hand, the erection of the protective wall element 17 on uneven ground 3, while allowing on the other hand, due to their areal limited extent in the passage and drainage of rainwater or the like below the protective wall element , In addition, results from the provision of Aufstellflächenelemente 47 in the connection region VB (see. Figures 1 and 2 ) an enlarged Antagefläche the protective wall elements 17 in the transverse direction, which together with the made or to be carried longitudinal clamping of the protective wall elements 17 for improved connection stability and transverse rigidity of the protective wall 38 of the invention provides (so-called. Below is based on the FIGS. 39 to 42 shown in more detail how the Aufstellflächenelemente can cooperate when connecting individual protective wall elements 17 to a protective wall.

FIG. 7 shows in detail in cross section an alternative embodiment of a protective wall element 17 according to the invention, which has a closed construction with a corresponding wall body element 18. In particular, the gap between two plane-parallel, plate-like horizontal struts 17a may be filled with a suitable filling material. Otherwise, the basic design essentially corresponds to that according to FIG. 6 ,

In particular, in view of the FIG. 7 however, with validity also for all further protective wall elements 17 according to the invention, it should be noted that they are regularly formed larger in the region of their height H than in the region of their width B, the width of the protective wall elements 17 being larger in the area of the mentioned cross-sectional widening 17d (reference symbol B ') as the width B in the region of the wall body element 18th

In FIG. 8 is again detailed the already by means of FIG. 6 addressed facts when connecting two protective wall elements 17 by means of a recessed into the recesses 19 ", 20" inserted or used profile element 46. It is intended in this context only to details of FIG. 8 are received, which are based on FIG. 6 not yet shown or described.

The profile element 46 is formed as a hollow profile with a rectangular cross-section, the dimensions of which essentially correspond to the dimensions of the recesses 19 ", 20" in order to be able to bring the profile element 46 substantially into the recesses 19 ", 20" in a form-fitting manner. At its top points the profile element 46 has a projecting stop structure 46a, which is arranged centrally with respect to its longitudinal extension of the profile element and serves to define a maximum penetration depth of the profile element 46 into the protective wall element 17 or the recess 19 ", 20" provided therein. Said projecting structure 46a cooperates with complementary notches 19 "', 20"' in the region of the recesses 19 ", 20", wherein the respective depth of the notches 19 "', 20"' is substantially just half the extent of the structure 46a in FIG Longitudinal direction of the profile element 46 corresponds. Thus, the projecting structure 46a is completely receivable within the combined sipes 19 "', 20"' in the case of the connected protective wall elements 17.

FIG. 9 shows the protective wall elements 17 according to FIG. 8 in advanced merge using the profile element 46, as already described above.

The following FIGS. 10 to 38 basically relate to the second variant of the protective wall according to the invention, in which the individual protective wall elements 17 are connected via vertical connecting elements 6 and optionally via horizontal connecting elements 7, 8 or corresponding setting-up and connecting devices 1.

According to the front view in FIG. 10 has a protective wall element 17 which is used in the second variant of the protective wall according to the invention, in the region of its end faces 19, 20 in addition to the already mentioned connection structure 23, 24 (opening for insertion of the clamping / connecting means 39) has a vertical connecting element 21, 22, which in particular with reference to the representation in FIG. 11 is clearly recognizable. The entire connecting element 21, 22 is in the form of a plan view in accordance with FIG. 11 formed in the cross-section U-shaped configuration in the region of the respective end face 19, 20, so that in the connection region VB between the end faces 19, 20 of the protective wall elements 17 to be connected, the vertical connecting element 6 can be accommodated or arranged, as in FIG. 11 shown. The tensioning / connecting means 39 is then guided through the apertures 23, 24 in the protective wall elements and through the vertical connecting element 6, which is designed to be suitable for this purpose, which will be discussed in more detail below.

The horizontal connecting element 7, 8 is in FIG. 11 again shown in dashed lines. It may form a structural unit with the vertical connecting element 6, which will be discussed in more detail below, or may in principle be formed separately from the vertical connecting element 6.

FIG. 12 shows a setup and connection device for protective wall elements, which is designated in its entirety by the reference numeral 1. The set-up and connecting device 1, which preferably consists of steel elements welded together, has a plate-shaped foot element 2, which serves for setting up on a substantially flat substrate 3, such as a road surface. The foot member 2 accordingly has on its underside 4 an unspecified footprint, which is covered with a slip-resistant and / or elastic material 5, which may be in particular vulcanized rubber or plastic. Perpendicular with respect to said mounting surface of the foot member 2, a vertical connecting element 6, which is designed as a square hollow profile extends. Furthermore, the set-up and connecting device 1 parallel to said mounting surface on two integrally formed horizontal connecting elements 7, 8, which are realized together in the form of a single U-profile element 9. The U-profile element 9 is arranged with its free legs 10, 11 on the base element 2 or on its upper side, while the vertical connecting element 6 is in turn arranged on the U-profile element 8 or on its middle leg 12.

As one skilled in the art will appreciate, an erection and connection device 1 according to the invention is not based on the in FIG. 12 shown and explained above embodiment limited. For example, the horizontal connecting elements 7, 8 may also be formed as separate units, that is, in two pieces. In this context, it is also possible that the vertical connecting element 6 rests directly on the base element 2, and that the two horizontal connecting elements 7, 8 laterally adjoin the vertical connecting element 6.

Furthermore, instead of a single base plate 2, of course, several separate plate elements may be present.

The horizontal connecting elements 7, 8 have over the foot element 2 in each case an excess ÜM in their longitudinal extent. In the area of the mentioned excess dimensions ÜM, an opening 13, 14 is arranged in the middle limb 12 of the U-profile element 9, which serves as a connection structure for detachable connection to a complementary connection structure (projection) of a protective wall element, which will be discussed in more detail below. Similarly, the vertical connecting element 6 in its upper, that is facing away from the foot member 2 section has an opening 15 which serves as a connection structure for releasably connecting to a complementary connection structure of the aforementioned protective wall element, which will also be discussed in more detail below. Since it is in the vertical connecting element 6 according to FIG. 12 is a square hollow profile, this has corresponding openings 15 in two opposite side surfaces, of which representational in FIG. 12 only one is recognizable. The two apertures 15 are connected via a sleeve element 16 arranged in the interior of the square hollow profile. The sleeve element 16 extends parallel to the U-profile element 9 or the horizontal connecting elements 7, 8 formed therefrom.

Again FIG. 12 It can also be seen that the horizontal connecting elements 7, 8 are spaced from the substrate 3 by the thickness D of the base element 2 (including the material 5 applied to its underside) in the area of the excess ÜM, which will be discussed in greater detail below.

FIG. 13 shows a side view of the installation and connection device 1 according to FIG. 1 , wherein the viewing direction is selected according to the longitudinal extent of the U-profile element 9.

FIG. 14 shows a plan view of the configuration of the set-up and connecting device 1 according to the Figures 12 and 13 ,

The representation in FIG. 13 In particular, the already mentioned total thickness D of the foot element 2, 5 can be seen, while the illustration in FIG FIG. 14 again the mentioned excess ÜM of the horizontal connecting elements 7, 8 relative to the foot member 2 illustrates.

FIG. 15 shows in perspective the overall view of a protective wall element 17 according to the invention for use with a set-up and connecting device 1 according to the FIGS. 12 to 14 , The protective wall element 17 consists essentially of a plate-shaped wall body or wall body element 18, which is preferably formed in a curable cast material, most preferably in concrete. In principle, it is also possible here to produce the wall body 18 by means of a hollow molding element which is filled with a suitable filling material, such as sand or water or the like. Also open configurations (cf. FIG. 1 ) are possible.

The plate-shaped wall body 18 has at its two opposite narrow end faces 19, 20 each have a vertical connecting element 21 and 22, which is formed as an H-shaped profile element. As those skilled in the art readily recognize, the vertical connecting elements 21, 22 serve to connect the protective wall element 17 to the vertical connecting element 6 of the set-up and connecting device 1 (cf. FIGS. 12 to 14 ). For this purpose, the protective wall element 17 in the region of the vertical connecting elements 21, 22 each have a connection structure formed as a breakthrough 23 or 24, which will be discussed in more detail below and which in FIG. 15 only hinted at.

The connection structures 23, 24 of the protective wall element 17 are designed to cooperate with the corresponding connection structures 15, 16 of the set-up and connection device 1.

Furthermore, the protective wall element 17 at its between the end faces 19, 20 arranged longitudinal narrow side 25 (below in FIG. 15 and there for illustrative reasons not visible) nor at least one horizontal connecting element, which is designed for cooperation with the horizontal connecting element 7, 8 of the set-up and connecting device 1. Also, the horizontal connection element of the protective wall element 17 has at least one connection structure that is complementary to the corresponding connection structure 13, 14 (see. FIG. 12 and FIG. 14 ) of the set-up and connecting device 1 is formed.

The horizontal connecting element of the protective wall element 17 will be described below with reference to particular Figures 16 and 17 explained in more detail.

Furthermore, the protective wall element 17 according to FIG FIG. 15 nor first and second transport / lifting elements 26 and 27 for lifting and transporting the protective wall element 17, which will also be discussed in more detail below. At reference numerals 28 and 29, the protective wall element 17 according to FIG. 15 Reflector elements, which are each referred to simply for the sake of clarity. The reflector elements 29 are arranged for their protection in recesses 30 of the wall body 18, which are distributed over the side surfaces of the protective wall element 17 at regular intervals.

FIG. 16 shows a perspective view of the bottom 25 of the protective wall element 17 according to FIG. 4 , The representation in FIG. 16 In particular, the design of the horizontal connecting elements of the protective wall element 17 can also be recognized. Accordingly, the protective wall element 17 has on its underside 25 a channel-shaped recess 31, which extends substantially over the entire length of the protective wall element 17. In the transverse direction, the groove-shaped recess 31 is slightly wider than the U-profile element 9 according to the FIGS. 12 to 14 educated. The channel-shaped recess 31 is bounded laterally by two L-shaped profile elements 32, 33 and otherwise in the vertical direction by the material of the wall body 18. Between the L-shaped profile elements 32, 33, which project laterally in the transverse direction over the side surfaces of the wall body 18 and form an integral footprint of the protective wall element 17, distributed over the length of the protective wall element 17 spacers 34 are arranged, which at least partially into the material of Wall body 18 are cast with. Reference numeral 35 denotes a special type of spacer elements, which are provided at the two ends of the protective wall element 17. This will be explained below on the basis of FIG. 24 discussed in more detail. How, however, already the FIG. 16 can be seen, have the spacers 35 each have a projecting (connection) structure 36, which for connection purposes with the openings 13, 14 of the U-profile element 9 according to FIG. 12 and FIG. 14 interacts.

The spacer elements 34 may also be formed in the manner of longitudinally oriented planar web plates 34 ', which may also be arranged vertically offset from each other. This is in the FIGS. 6 . 8th and 9 as well as in the FIGS. 27 to 29 exemplified. However, this concept is basically also applicable to protective wall elements 17 with a closed design.

As the person skilled in the art will readily recognize, the protective wall elements 17 are according to FIG FIG. 15 or 16 because of the lateral profile elements 32, 33 alone stand-alone, so basically do not need a positioning device 1 according to the FIGS. 12 to 14 ,

FIG. 17 shows the protective wall element 17 from FIG. 15 and FIG. 16 based on a side view overlooking one of the narrow end faces 19, 20. Off FIG. 17 In particular, the position and configuration of the apertures 23, 24 and the projecting structure 36 can be easily taken.

The vertical connecting elements 21, 22 of the protective wall element 17 are formed as H-profile elements, wherein the wall body 18 (in FIG. 17 not visible) in the (rear) free space between the parallel legs of the H-profile element 21, 22 engages. The in FIG. 17 recognizable front space 37 serves to receive the vertical connecting element 6 of the installation and connection device 1 (see. FIGS. 12 to 14 ) which will be described below with reference to FIGS. 18 to 21 will be discussed in more detail.

First, however, based on FIG. 18 even more specific to the embodiment of the already mentioned first lifting and transporting element 26 (cf. FIG. 15 ). This comprises, according to the present embodiment of the protective wall element 17, two parallel bar elements 26a, 26b which extend in the longitudinal direction of the protective wall element 17 and which are fastened with their one end to the H-profile element 22 and with its other end to an angle part 26c, preferably through Welding, wherein the angle part 26c a recess 26d defined in the wall body 18. The rod elements 26a, 26b can be detected by means of a cable or a hook to lift or transport the protective wall element 17.

Furthermore, the opening 24 opens in the region of the recess 26d, which will be discussed in more detail below.

The following is now based on the FIGS. 18 to 21 the assembly and connection of two protective wall elements 17 with a set-up and connecting device 1 described in more detail. For lifting and positioning of the protective wall element 17, the first lifting and transporting elements 26 and / or the second lifting and transporting elements 27 (cf. FIG. 19 ) be used. The second-mentioned lifting and transporting element 27 is designed for use with an eccentric gripper and has for this purpose a preferably hemispherical recess 27a and a centrally disposed therein pin or bolt 27b with a terminal thickening.

First, the wall element 17 is brought laterally in the raised state to the erection and connecting device 1, so that the vertical connecting element 6 engages at least partially in the free space 37 of the H-profile element 22. The direction of movement of the protective wall element 17 essentially corresponds to the arrow P1 in FIG FIG. 7 ,

Subsequently, the protective wall element 17 according to the arrow P2 in FIG. 19 lowered until it rises with the outwardly angled legs of the L-profile elements 32, 33 on top of the foot member 2. In this position, the opening 15 and the sleeve 16 of the vertical connecting element 6 are aligned with the opening 24 in the H-profile element 22 (see. FIGS. 18 and 19 ). In addition, the protective wall element engages with its projecting structure 36 according to FIG. 17 in the opening 13 of the installation and connection device 1 a (see. Figures 17 and 18 ). In this way, a temporary, releasable connection between the protective wall element 17 and the installation and connection device 1 is effected. Since the protective wall element 17 with its L-profile elements 33, 32 rests on the base element 2, a gap remains below the protective wall element 17, through which rainwater or the like can run under the protective wall element 17.

In FIG. 20 is the situation in the right part of the figure FIG. 19 presented from a different angle. From the left is in FIG. 20 analogous to FIG. 18 another protective wall element 17 introduced (arrow P3) and then lowered (arrow P4). Then also the opening 23 is aligned with the sleeve 16 and the corresponding openings of the installation and connection device 1 (in FIG. 20 not visible) on the one hand and with the opening 24 of the other protective wall element 17 on the other. The protruding structure 36 (in FIG FIG. 20 also not visible) of the left protective wall element 17 then engages in the opening 14 of the installation and connection device 1 a.

The situation after the lowering of the left protective wall element 17 is in FIG. 21 again from the same perspective as in the FIGS. 18 and 19 shown. For releasable bracing of the protective wall elements 17 to a protective wall 38 according to the invention is then according to FIG. 21 a clamping and connecting means 39 in the form of a screw through the apertures 15, 23, 24 and the sleeve 16 is guided to releasably connect the protective wall elements 17 through the vertical connecting element 6 therethrough. The screw 39 is secured in the region of the recess 26 d of a protective wall element 17 with a nut 40; the screw head 41 is located in the region of the recess 26d of the other protective wall element 17.

FIG. 22 shows the connection between the two protective wall elements 17 again in detail in a plan view. Here are the above based FIG. 21 already described features of the clamping connection between two protective wall elements 17 even more accurately.

According to the FIGS. 18 to 22 corresponds to the entire width of the protective wall element 17 in the region of the L-profile elements 32, 33 just the width of the foot member 2. However, the invention is in principle not limited thereto. For example, the width of the protective wall element 17 in the region of the L-profile elements 32, 33 may also be smaller than the width of the foot element 2.

FIG. 23 shows an overall perspective view of a protective wall 38 consisting of two protective wall elements 17 and three erecting and connecting devices 1. Of course, the protective wall 38 shown can be extended on both sides by further protective wall elements 17.

FIG. 24 shows an embodiment of the protective wall element 17 before an introduction in particular of concrete for producing the wall body 18, which according to in FIG. 24 not shown. In the interior of the protective wall element 17, effective reinforcing or reinforcing structures 42 and 43 and associated holding structures 44 are provided on the one hand in the longitudinal and transverse direction, which are poured in during the casting of the wall body, in order to give them the necessary stability, in particular tensile strength. At reference numeral 35, in turn, the already mentioned spacer element can be seen, which cooperates with the already mentioned holding structure 44 and at the same time carries the projecting structure 36.

After attaching a lateral formwork, the protective wall element 17 with respect to the representation in FIG. 24 upside down and filled in the direction of arrow B with the wall body material, preferably concrete, until this reaches approximately the level N. The filling material then fills the whole in FIG. 24 hatched area within the protective wall element 17 except for the area indicated by reference numeral 26d within the element 26c.

In FIG. 25 the protective wall element 17 is shown again before filling the filling material, wherein the reference numerals to those in FIG. 24 correspond. Well recognizable in FIG. 25 nor the pin or bolt element 27b for the second lifting and transport element 27 (see. FIG. 19 ). The transverse reinforcements 43 extend according to FIG. 25 at an angle α = 45 ° with respect to a median plane M of the protective wall element 17. The longitudinal reinforcements 42 are received in lateral recesses 45 of the support structure 44.

FIG. 26 shows an embodiment analog FIG. 23 However, wherein the left, terminal protective wall element 17 'of the protective wall 38 is formed as a protective wall terminating element and as such has a decreasing height H towards its free end 17a'. There, the protective wall element 17 'also still attachment structures 17 b' in the form of openings for anchoring in the underground and a bow-shaped lifting device 17c 'for transport.

FIG. 27 shows in detail and analogous to FIG. 19 Otherwise, the function and design of the protective wall element 17, in particular as regards the interaction with the set-up and connecting device 1, substantially the same as above with reference to the FIG. 19 described circumstances. It should be noted at this point, however, that the protective wall element 17 in the region of its upper horizontal strut 17a, the already mentioned recess 26d for inserting the (not shown) clamping / connecting means 39 has. In addition, missing in the protective wall element 17 in FIG. 27 compared to the embodiment, for example in FIG. 8 or 9 the central horizontal strut 17b, the entire design is even more open and easier. Furthermore, in the lower region of the protective wall element 17 according to FIG FIG. 27 provided to provide this in the region of the horizontal strut 17c with openings 17c ', which does not adversely affect the stability or rigidity of the protective wall element, however, leads to a further material and weight savings.

The following FIG. 28 turns out FIG. 27 analogous to the transition from FIG. 19 to FIG. 20 , so that in this respect further explanations are unnecessary. The same applies to the representation in FIG. 29 in comparison with the illustration in FIG. 21 and its description.

FIG. 30 shows analogously to FIG. 23 two open protective wall elements 17, which are connected to a protective wall 38, wherein an erecting and connecting device 1 according to the invention is used in each case between pairs of protective wall elements 17.

The FIGS. 31 to 33 clarify again possible attachments of reflectors 28, 29 in inventive protective wall elements 17th

The FIGS. 34 and 35 can be seen as in a protective wall 38 according to the invention by appropriate adjustment of the tension band in the form of clamping / connecting means 39 in the course of the protective wall 38 in the vertical perpendicular to its longitudinal extent to unevenness of the Aufstell-subsurface 3 adapt.

The representation in FIG. 34 represents the situation when installing the protective wall 38 in a sink. The drawn angle β between the individual protective wall elements 17 is β <180 °. This corresponds in principle to a deviation of the footprint 3 from the dashed line horizontal HO or any flat reference surface.

According to FIG. 35 If the situation is different, here is the protective wall 38 in the region of a dome, so that applies for the said angle: β> 180 °. By appropriate adjustment of the tension band (tighten or loosen the clamping / connecting means 39) can be despite the occurring wedge-shaped gap between the end faces 19, 20 of the protective wall elements secure and effective clamping of the same against each other. The foot element 2 of the installation and connection device 1 provides the necessary compensation possibility in the vertical direction.

FIG. 36 clarified in sub-figures a) to c) again in juxtaposition of possible embodiments of the horizontal connecting element 7, 8 relative to the longitudinal extent thereof. In subfigure 36a), a single, virtually endless horizontal connecting element 7, 8 is provided with length a, which is designed to be continuous at least over a plurality of protective wall elements 17. In part- Figure 36b ) is assigned to the vertical connecting element 6 at least one "own" horizontal connecting element 7, 8, whose total length b corresponds to the length of a protective wall element 17. However, the vertical connecting element 6 is arranged substantially centrally with respect to the associated horizontal connecting element 7, 8, so that the horizontal connecting element 7, 8 connects two adjacent protective wall elements 17 with one another. This embodiment is basically not limited to a central arrangement of the vertical connecting element 6 relative to the horizontal connecting element 7, 8. Furthermore, the horizontal connecting element 7, 8 - as already mentioned - in particular be formed in two parts, with an arm 7 of the horizontal connecting element on one side and the other arm 8 of the horizontal connecting element on the other side of the vertical connecting element 6 extends.

According to part of Figure 36c, the horizontal connecting element 7, 8, which may otherwise be configured according to part figure 36b, a longitudinal extent c, which is shorter than the corresponding extent of the protective wall elements 17. Obviously, this results in a significant material savings in the field of set-up and connection devices ,

Finally, the show Figures 37 and 38 schematically again two basic embodiments of the horizontal connecting element 7, 8, as they can be used in the context of the present invention.

According to FIG. 37 the horizontal connecting element 7, 8 is completely received in a recessed area in the bottom 25 of the protective wall element 17. The protective wall element 17 is in the region of its cross-sectional widening 17d on the substrate 3, and the horizontal connecting element 7, 8 serves essentially exclusively for transverse fixation or transverse stabilization of the protective wall element 17 or a protective wall composed of such protective wall elements 17 protective wall.

According to Figure 38 also has the horizontal connecting element 7, 8 a preferably also based on their transverse dimension of the cross-sectional widening 17d of the protective wall element 17 corresponding lower side widening 7 ', 8', which may be formed for example by the above already mentioned several times foot element 2 of the installation and connection device , Accordingly, the horizontal connecting element 7, 8 not only serves for transverse fixing or stabilizing, but at the same time also assumes an upright function which is effective in the vertical direction relative to the substrate 3 in order to compensate for unevenness in the installation, cf. FIGS. 34 and 35 ,

• Die Schutzwandelemente 17 gemäß Figur 39 besitzen an ihren Unterseiten im Stoßbereich jeweils mindestens ein Aufstellflächenelement 47, welches in Längsrichtung ein Stück weit über die Endstirnseite 19 bzw. 20 des jeweiligen Schutzwandelements 17 hervorsteht, so dass sich gemäß der Darstellung in Figur 39 ein lichter Abstand d zwischen den genannten Endstirnseiten 19, 20 ergibt, wenn die Aufstellflächenelemente 47 aneinander in Druckstoß-Anlage treten, was in Figur 39 durch das Bezugszeichen DS symbolisiert ist. Die Spann-/Verbindungsmittel 39 sorgen wiederum für die gewünschte Längsverspannung der Schutzwandelemente 17, so dass sich eine Zug-Druck-Verbindung ergibt.

The representation according to FIG. 39 is essentially the same as in FIG. 2 , so that only a few special features are explained below:

• The protective wall elements 17 according to FIG. 39 have at their bottoms in the joint area in each case at least one Aufstellflächenelement 47, which in Longitudinally protrudes slightly beyond the end face 19 and 20 of the respective protective wall element 17, so that, as shown in FIG FIG. 39 a clear distance d between the said end faces 19, 20 results when the Aufstellflächenelemente 47 contact each other in a pressure impact system, which in FIG. 39 symbolized by the reference DS. The clamping / connecting means 39 in turn ensure the desired longitudinal tension of the protective wall elements 17, so that there is a train-pressure connection.

FIG. 40 shows the same facts for a better understanding again in plan view.

The construction according to the FIGS. 41 and 42 On the other hand, it corresponds essentially to that according to those already described FIGS. 8 and 9 , so that on this principle is not to go further. Deviating from the illustration according to FIG. 8 or 9 is however also according to the FIGS. 41 and 42 provided that between the end faces 19, 20 of the protective wall elements 17 to be joined a distance d remains when the lower side Aufstellflächenelemente 47 are in the pressure surge DS. This in turn results in the already mentioned train-pressure connection.

To describe the illustration according to FIG. 43 will be explained in detail on the above FIG. 22 Referenced. Here, too, DS results in a pressure surge between the terminal end faces of the L-profile elements 32 and 33, which in conjunction with the tension given by the screw 39 (with screw head 41 and nut 40) for the already mentioned train pressure Connection ensures - according to FIG. 43 again with the interposition of a vertical connecting element. 6
