DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] FIG. 1 schematically shows a perspective view of an embodiment of a supporting device 1 according to the invention with a textile transverse force reinforcement 5 according to the invention, wherein the supporting device 1 is curved in the plane. The curvature is made possible by a center chain 3 comprising individual links 15.

[0059] Each link 15 of the center chain 3 can be connected to a support element 2 in the region of node point 19. The support element 2 can be provided with fixing pins 7 over which a yarn 17 can be laid. Appropriate placement of the yarn 17 around the fixing pins 7 results in the transverse force reinforcement 5, which can be produced by the supporting device 1 according to the invention. Using shaping actuators 6, the desired curvature can be achieved without manual intervention.

[0060] FIG. 2 schematically shows an exploded perspective view of an embodiment of a supporting device 1 according to the invention with the transverse force reinforcement 5 to be produced. The curvature of the supporting device 1 with the support elements 2 is made possible by the center chain 3, which comprises the individual links 15 with the two-node points 19 in each case, and is caused by the action of the shaping actuators 6. In addition to the form actuators 6, compensating strips, 4 are also involved in causing the curvature. The compensating strips 4 transmit the force effect of the shaping actuator 6 and enable a uniform curvature over the entire length of the supporting device 1, although the shaping actuators 6 in themselves only act locally on the supporting device 1.

[0061] FIG. 3 schematically shows an embodiment of the process sequence according to the invention for producing the transverse force reinforcement 5 with the aid of the supporting device 1 according to the invention in four steps a) to d). First, according to the letter a), the supporting device 1 is placed on a supporting surface 18 on which the center chain 3 and the individual support elements 2 of the supporting device 1 provided with fixing pins 7 can slide as well as possible, at least during alignment or bending

[0062] In the second illustration, under letter b), the curvature has already been produced. The yarn 17 is deposited over the fixing pins 7 until the complete transverse force reinforcement 5 is formed as in letter c). The yarn 17 has preferably been impregnated with a curable material before being placed. After it has cured, the now completed transverse force reinforcement 5 can be removed from the fixing pins 7 of the supporting device 1 and is thus ready for use. The completed transverse force reinforcement 5 detached from the supporting device 1 is shown under letter d).

[0063] FIG. 4 schematically shows a perspective view of the center chain 3 with the attached support element 2 of an embodiment of a supporting device 1 according to the invention. The center chain 3 comprises the individual links 15, each of which is provided with one of the node points 19 so that the links 15 can pivot about a node point axis 20 by a certain angle. This enables the curvature of the center chain 3 and thus the intended position of the support elements 2 arranged on the center chain 3.

[0064] Furthermore, the support element 2 is shown as it is placed with its support element base body 13 centrally on the center chain 3 in the region of the node point 19. On its two arms pointing away from the center chain 3, the support element 2 has a pin receptacle 12 in each of which a fixing pin 7 with its pin seat 8 can be inserted.

[0065] In addition to the possibility of moving the support element 2 with the respective link 15 in a limited rotational movement or a pivoting movement when the center chain 3 is curved, a clearance 14 on the underside of the support element 2 facing the center chain 3 also allows it to move relative to the center chain 3. Furthermore, the clearance 14 ensures the mobility of the links 15 in the first place when they are in the area of a support element 2. The clearance 14 thus defines the angle by which the links 15 can be brought or pivoted towards each other around the node point axis 19. In the node point axis 19, the hinge 27 is formed by the hinge head 25 and the recess 26 in the support element 2. For a better understanding of the structure of the hinge 27, reference is made to FIG. 5.

[0066] FIG. 5 shows schematically in perspective exploded view a center chain 3 with attached support element 2, shown in sectional view, of an embodiment of a supporting device 1 according to the invention. Essentially the situation of FIG. 4 is shown, whereby the links 15 separated from the center chain, 3 show the structure and mode of operation of the node point 19. Here, each link 15 has a respective elevation, a hinge head 25, on which an annular element, a hinge ring 28, of the next following link 15 can be placed. The node point 19, comprising the main part of the hinge 27, is formed by the interaction of the hinge head 25 and the hinge ring 28. Accordingly, the hinge 27 is formed by the hinge head 25, the hinge ring 28 and also the recess 26 in the support element 2. The clearance 14 on the underside of the support element base body 13 allows the support element 2 to swivel in the plane.

[0067] FIG. 6 shows schematically in perspective view a support element 2 with disassembled fixing pins 7 or in the position before assembly as part of an embodiment of a supporting device 1 according to the invention. The fixing pins 7 each have the pin seat 8, which is accommodated by the pin receptacle 12 in the support element base body 13 during assembly.

[0068] The pin seat 8 is adjoined by a pin body 9, which has a groove 10. The yarn is inserted into groove 10 when the yarn is deposited and secured there against slipping, provided that there is sufficient yarn tension. The upper end of the fixing pin 7 facing away from the support element 2 is formed by a head 11.

[0069] The recess 26 and the clearance 14 allow the support element 2 to pivot.

[0070] FIG. 7 shows schematic and partly cut side views of various embodiments of fixing pins 7 as used in the supporting device 1 according to the invention. Here, under letter a), a fixing pin 7 is shown as already known from the previous figures. However, a special feature is the screw head 24, which, in cooperation with the pin seat 8 designed as a thread, enables the fixing pin 7 to be screwed into the support element 2 or the support element base body 13. The screwing in can be carried out manually or automatically, whereby in the latter case, the advantageous removal of the fixing pins 7 takes place from a magazine.

[0071] The same embodiment of the fixing pin 7, but in a partially cut representation and with the deposited yarn 17 inserted in the groove 10, is shown in letter b).

[0072] A similar embodiment is shown in letter c) but with a greater length of the pin base body 9. As a result, groove 10 is in a different position and allows a transverse force reinforcement to be produced with different dimensions, particularly with a greater height. An equally large length of the fixing pin 7 is shown in the illustration under letter d), whereby in addition to the upper groove 10, as can be seen in the illustration under letter c), there is a further groove 10 arranged underneath. This also has an inserted yarn 17 in the illustration according to letter d). Furthermore, a pin axis 16, the head 11, the pin base body 9, and the pin seat 8 are shown and designated.

[0073] Another embodiment of the fixing pin 7 can be seen under letter e), again including the deposited yarn 17. In contrast to the previous embodiments, there is no groove in the pin base body 9, but instead a pin coating 22, which is soft enough to allow the yarn 17 deposited under tension to leave a temporary indentation. In this recess, the yarn 17 is fixed and secured against unintentional movement along the pin axis 16, particularly against slipping downwards.

[0074] In the embodiment according to letter f), the pin base body 9 is telescopic and can be lengthened and shortened according to the specific requirements. In this case, groove 10 is arranged in the upper, movable part of the fixing pin 7. By extending or retracting the telescopically movable part of the pin base body 9, the vertical position of the groove 10 can thus be set up and adjusted accordingly.

[0075] FIG. 8 shows a schematic representation of mechanically coupled support elements 2 of an embodiment of the supporting device 1 according to the invention with a partially curved center chain 3. In this case, the support elements 2 or their support element base bodies 13 can no longer be freely pivoted with respect to the center chain 3 and around the node point 19, but instead, adjacent support elements 2 are mechanically coupled to each other in each case. This enables a defined relative movement. Unpredictable, incorrect, or unstable positions of the individual support elements 2 are avoided. In the embodiment shown, the mechanical coupling is implemented via gear segment 23, whereby the teeth of the gear segment 23 of the adjacent support elements 2 mesh with each other.

[0076] FIG. 9 shows a schematic sectional view of a support element 2 with a magnet 21. Magnet 21 makes it possible to fix the center chain 3 as well as the support element 2 to the support surface 18. For this purpose, the support surface 18 must be made of a magnetic material, for example, steel. Furthermore, in the illustrated embodiment, element 2 is equipped with a magnetic element, magnet 21.

[0077] The magnet 21 not only ensures a secure connection between the individual parts joined together in the area of node point 19, but also still allows an appropriate mobility of the thus connected elements among each other. A clamp effect is created at least between three parts, the two links 15 of the center chain 3, which lie one above the other in the node point 19 as a hinge 27 (shown here in a simplified form without a joint ring), as well as the support element base body 13. Alternatively, one of the links 15 is clamped between the following link 15 and the support element base body 13 by the magnetic force. This effect is still achieved even if no support surface 18 made of a magnetic material is applied.

[0078] FIG. 10 shows a schematic perspective view of three different embodiments of the transverse force reinforcement 5 formed by means of yarn 17 according to the invention with different cross-sections, with which the two shells of a concrete sandwich structure can be reinforced and connected at the same time. In the letter a), the transverse force reinforcement 5 has a U-shaped profile, while the representation in letter b) has the cross section of a double-T beam (wide flange beam). A different cross-sectional shape is shown in letter c) and underlines the wide variety of cross-sectional shapes that can be produced. All three embodiment examples have in common that the transverse force reinforcement 5 is designed curved in the longitudinal direction.

[0079] FIG. 11 shows a schematic perspective view of an embodiment of a concrete component 70. In the embodiment shown, this is illustrated as a sandwich element comprising two shells. Concrete structural modules 72 of the two shells are each connected by a separate edge connection 40. The region shown without concrete cover illustrates the interlocking of yarn loops 30, each belonging to a reinforcement mesh 50 of both concrete structural modules 72.

[0080] Furthermore, the transverse reinforcement is shown 5, which both engages the two shells of the sandwich element and represents the connection and spacing structure between the two shells.

[0081] Further, a grid tubular reinforcement 48 is provided to allow and dissipate high forces in the intended direction, the longitudinal extent of the grid tubular reinforcement 48. The grid tubular reinforcement 48 is also suitable for dissipating forces across several concrete structural modules 72. For this purpose, reinforcement cable 49 is preferably inserted into the interior of the grid tubular reinforcement 48 and connects the concrete structural modules 72. In particular, in the event of a structure being overloaded, additional protection can be achieved in this way.

[0082] According to an alternative embodiment, the grid tubular reinforcement 48 may also be routed across several concrete structural modules 72 when the concrete is placed after the concrete structural modules 72 are connected.
