The invention relates to a bearing for a supporting structure the rubber, in particular for the horizontal and Made of an elastically resilient material, preferably vertical torsion stress, this is essential Rubber, with crosswise arranged rails - rather meaning, since the rubber over several of reinforcing bars or threads made of metal, avoid layers under favorable conditions or plastic. 5 what happens when using a fully

In known bearings of this type, the rubber bearings built for term steel plates do not exist Reinforcing certain layers mostly made of steel- the case. The reinforcement can be used for such wire or plastic fiber braids, which are laid out loosely between rubber bearings in such a way that the Schubschen rubber plates are inserted. Such stress between the individual reinforcement structures Camps have the disadvantage that the loose single rods or threads and the rubber are common to all Braids are too weak to withstand the types of rubber load that the well-known steel plate reinforcement bodies have to give the desired stiffening. This tion is equivalent. The individual take over Braids tear the same function as with a relatively small amount of reinforcement bars or threads Load. Since the braid closes at the beginning of the load - a continuous plate or the one that is basically next to you If the rubber body is imprinted, there are 15 additional grids or meshes that are to be equated a shift in the beginning of the spring action, and offer the advantage that the bearing both vertiwas the practical use of such a historical as well as horizontal torsional stresses very much teten camp. absorbs well and even with high turning loads

In order to eliminate this disadvantage, wire mesh cracks are no risk of detachment of the rubber already worked into the rubber body at the crossroads of the reinforcement during the manufacture of such bearings for Trag- ao. Occurs to rods or threads of adjacent layers. Each for this purpose the braids and rubber reinforcement layer represents a tension plate in one dimension layered on top of each other and represents a solid surface, which is welded opposite the neighboring piece. As a further advantage, a reinforcement part with tensile strength, also in one dimension, can be achieved with the use of metal layers at 90 ° with respect to the tensile strength of vertical rods or threads. The disadvantage, however, is sets. As a result, a significantly larger volume can be claimed in an advantageous manner for the relatively small torsional deformations in this bearing as well. The transverse contraction depends on the rubber for the deformation,

Such bearings can be made of steel and rubber. The area is the torsional loads only to a small extent, shear transmission of decisive importance, record, which is why one has already switched to this - compared to one made of full-layer steel, lay the metal rods loosely on top of each other. 35 rubber mounts built on plates can be adjusted depending on

In particular, combinations should be achievable.

Starting from the bearing 55 mentioned at the beginning, this is possible with a plate. However, in this object is achieved according to the invention by adding a shift to each layer, mainly in that each layer of unidirectional reinforcing bars one across the individual reinforcing bar or thread or threads from the adjacent layer take place in a trending direction, d. i.e., the individual Krcu distances is arranged.
