In the main patent, among other things, a concrete wall that is to be cast transversely to its direction for the construction of a stable spatial reinforcement lattice serving lattice stands placed under protection, at a distance parallel to the formwork to accommodate clamping elements serving rod pairs or the like, which are connected to one another via cross struts «. · »

Such a reinforcement lattice is initially used to set up and secure the cladding. After this Pouring concrete and setting the concrete, the latticework in question remains in the formwork and serves as rebar. The advantage lies in the simple, time-saving and precise installation of reinforcement and formwork, which is possible on both sides at the same time. Conventional shuttering boards and shuttering panels can be used will. Furthermore, after the casing has been removed, there are no more bars going through the entire wall, which allow moisture to penetrate.

According to the main patent, the grid stands are used to build Round bars running parallel to the formwork at a distance have been proposed in such an arrangement, that in each case two opposing pairs of dog rods with each other via transverse and inclined struts are connected, which are welded to the pairs of dog rods or welded into the spaces between them are. Now, however, it cannot be avoided that one or the other welding point is always bad and tears under heavy use, after which the relevant pairs of fret bars no longer have a force as intended can be transferred to the transverse struts. According to the present invention, this disadvantage becomes thereby avoided that the cross struts grip around the rod pairs like a hook. The cross struts can according to the invention consist of flat steel bars, the ends of which to dog hooks with a radius of curvature corresponding to the Radius of the dog sticks are bent. According to a further feature of the invention, two can each be a pair of round bars encompassing flat steel bars reach through the concrete wall and connected in the middle, e.g. be welded together.

According to another development of the invention, the special one for reinforced concrete walls of greater wall thickness is suitable, it is provided that the flat steel cross struts on each side of the concrete wall consist of a single piece of flat steel, the inwardly directed sections of which are connected to one another. Included the flat steel struts can form open loops at the ends facing each other and via brackets be connected to one another, the clamp legs are tucked into the loops. This lattice stand is particularly suitable for wall thicknesses of over 50 cm the peat making of standard posts from round bars with loops forming flat steel cross braces, which are then connected to one another at the place of use by means of Klaanern running across the anchor work, whereby the Qeeamtgitteretänder through appropriate adjustment the length of the brackets is adapted to the desired wall thickness.

With the prefabricated lattice stands you can the hooks of the flat steel bars are welded to the round bars, which facilitates transport and assembly.

In the case of the lattice stands with loops, further round bars can be placed in the loops at such a distance be welded from the loop ends so that the chamber legs can be pushed through.

After the concrete has set and the turnbuckles loosened and removal of the shuttering boards is planned, grease the remaining holes in bit concrete after pulling out the bolts. In the case, that facade panel !! of any kind are to be attached, according to the invention, these plates by

Fig.l and 3 show a simple lattice stand according to the invention. Stand opposite each other in pairs two vertical round bars 3 'of which in Fig. 1 the rear one is covered by the front one. This continuous Rods 3 are connected by transverse struts 30 arranged at suitable intervals. Pig.3 shows a such cross brace. It consists of two flat steel strips welded to one another in the middle part, their ends are bent apart and in a radius which corresponds to the radius of the round bars 3, so curved inward are that the curvature hooks 32 include the round bar *. At this point they are also used welded to the rods. 5 shows a wall clad with such a lattice stand 2 in section. The vertical round bars 3 are embedded in the concrete foundation and are represented by a number of in FIG Cross struts 30 connected to one another. The cladding boards 13 »are attached to these cross struts explained in the description of the main patent, connected by means of turnbuckles that the shuttering boards or Formwork panels 13 against the rod pairs 3 attacking Press spacer 6. ! Drag timbers 15, tensioning wedges 17, tensioning anchors 10 and on the inside of the round bars 3 arranged counter nuts 12 complete the turnbuckles.

After the concrete has set, the turnbuckles are loosened and all parts except for the nuts 12, which are in the Concrete remain removed. The holes caused by the spacers are smeared with concrete.

In the event that facade panels 40 of any Kind to be attached to the outer wall, this can be done with suitable screws through the from the spacers 6 recessed holes in the nuts 12

2 and 4 show a standard lattice stand 2 ·, which is relatively easy to different Wall thicknesses must be adapted and is particularly suitable for higher wall thicknesses, e.g. from 50 cm upwards. As can be seen from the sectional drawing of Pig. 4, the flat steel comprising the rod pairs 3 form hook-like rods 31 inwardly a loop into which another rod 3 is welded at a distance from the end of the loop is. Clamps with their clamp legs 37 are inserted into the loops themselves, with how Pig. 2 shows the clip legs 37 each a pair Overlying loops of flat steel letters can capture.

It is readily apparent that such a lattice stand can be made by selecting the width of the clamps accordingly the respective wall thickness can be adjusted without that something has to change in the rest of the files. This has the advantage that the storage is extraordinary is simplified.
