Description

The invention relates to a construction bearing made of resilient material with centric spacing Ring-shaped reinforcement inserts embedded one above the other.

A construction warehouse of the type mentioned at the beginning is through the DE-PS 11 79 978 or. DE-OS 2148 622 (Fig. 2) known. The disadvantage here is that the reinforcement inserts have the same ring diameter, which is why with Einhalturi ;;: the minimum distance between the reinforcement inserts the cross-section of each individual reinforcement insert is limited to larger cross-sections require a greater storage height. To avoid this disadvantage Mnd at one of the known construction bearing rings with very small cross-sections arranged concentrically or spirally (DE-AS 11 79 978), which is expensive.

The invention is based on the object To create inexpensive construction stores with greater stability at a low height.

This is achieved according to the invention in that the Diameter of at least part of the rings of the reinforcement layers compared to that of the rest Reinforcement inserts is dimensioned smaller and that the assignment of the reinforcement inserts to one another in such a way is that above and / or below each reinforcement insert one with a larger or smaller ring diameter is arranged.

What is achieved thereby is that, contrary to the case of an aligned arrangement of the reinforcement inserts, so measured the prior art of only a very short distance the forces that occur between the individual reinforcement layers in the training according to the invention can distribute on a much larger material area, so that the bearing body is less extreme is stressed and thereby its service life is extended.

The arrangement of ring-shaped reinforcement layers with different diameters is in itself known from DE-PS 12 03 812, but there are the ίο Reinforcement layers in direct contact with one another, so that the problem underlying the invention is a There is no lower stress on the material between the individual reinforcement layers is.

A further embodiment of the invention is the subject of claim 2.

The invention will then be described with reference to an embodiment shown in the drawings. It shows

In the F i g. 1 and 2 is a construction bearing 10 made of natural or synthetic rubber / ni in the built-in State shown which the load of a supported component 12 is elastic on a lower component 14 The construction bearing 10 consists essentially of an elastomeric bearing body 16 in which a number are embedded by tensile stressed annular reinforcement inserts 18. The Bearing body 16 made of a natural rubber with a hardness between 40 to 50 short, as this at different temperature changes the most uniform Shows a significant increase in the shear modulus of some synthetic rubbers Shear modulus with comparable temperature reductions demonstrate.

Since natural rubber is less resistant to ozone and the effects of the weather, a cover 28 (FIGS. 1 to 8) can be provided on the circumferential surface 2Λ . The preferred material for cover 28 is chloroprene rubber because of its superior resistance to ozone and weathering. However, other materials, such as certain types of butyl rubber, ethylene polypropylene rubber, polysulfide rubber, silicone rubber, and the like, can be used, with durability and price considerations as important. The construction store 10 has the shape of an inverted truncated cone. The bearing body 16 is delimited by the lower side 20, the upper side 22 and the peripheral surface 24. According to FIGS. 6 to 8, instead of the truncated cone shape according to FIGS. 2 and 5 have the shape of a circular cylinder with a small height (disk shape).

F i g. 5 shows a partial queniclinity by the Construction warehouse 10 along line 5-5 in FIGS. I and 3. The ring-shaped reinforcement insert η 18 are aligned along the circumferential surface 24 arranged. The Fig.5 to 8 show different arrangements of the reinforcement insert !! 18. Figures 1, 2 and FIGS. 5 to 8 show basic arrangements of reinforcement inserts 18. The sum of the diameters all cross-sections of the reinforcement systems 18 should be equal to or greater than 0.4 times the thickness of the bearing body 16.

If a load acts on the construction bearing 10, the bearing material tends to be incompressible Fluid to act and to transfer forces in all directions. In the case of a pressure load, there is indeed a

The non-delimited area between the underside of the circumferential surface 24 perpendicular to the underside and the upper side 20 or the top 22 and the respectively closest 20 and 22 is arranged three annular reinforcing bars Reinforcement insert 18 is noticeably less thick than io inserts 18 are embedded on the circumferential area 24, at the areas between the reinforcement layers 18 around which the upper and lower reinforcement layers 18 one a friction of the loaded and unloaded bearing material larger diameter than the mean Bewehmngseinan to prevent the components. The construction warehouse can have a position of 18. The total height of all rebar combination bearings be formed, the multiple layers 18 is not less than about 40% of the thickness of the Construction camp united (F i g. 3), whereby it is possible, the 15 bearing body 16. As can be seen, the lateral Construction store in a rectangular recess, spacing between adjacent reinforcement inserts to be arranged, which is usually provided. In the case of a vertical compressive stress on the support body Embodiment according to FIGS. 3 and 4 are the two 16 without much downsizing of the effective removal building camps 10 connected in one piece by means of a web 34. between adjacent reinforcement layers, such as The bearings behave essentially like the bearings 20 when the outer edge is aligned in the vertical direction F i g. 1 and 2. It is also possible for more than two reinforcements to be used in the event of internal loads Bauiager OK would be united in one camp and would appear in the construction camp, although the reduction of each Desired geometric arrangement, depending on the distance between neighboring moving objects the size and shape of the support to be supported is linear to the compressive stress. Component 12 and the available support surface on the 25 Therefore, the bearing body is less stressed than Component 14, be united. For example, three of the layers with reinforcement layers can be used with the same Bearing body 16 in a triangular arrangement use ring diameter, which has a beneficial effect on the service life det are etc. of the construction warehouse.

The arrangement of ring-shaped reinforcement inlay F i g. 7 shows an embodiment similar to that of FIG Gen 18 with different ring diameters allowed 30 Fig. 6, but the middle has ring-shaped reinforcement it, reinforcement layers with a larger insert 18 a larger diameter than that To use cross-section, creating a larger adjacent and therefore reaches closer to the total circumferential height the heights of all reinforcement layers in area 24.
