Tilting bearings that can be moved on all sides for bridge structures or the like.

The innovation relates to a tilting bearing that can be moved on all sides for bridge structures or similar facilities. It is known to use spherical shells as bridge bearings, which allow a tumbling movement. It is also already known to provide the hollow spherical shell with a plastic coating in order to reduce the friction as much as possible.

According to the innovation, it is proposed that the clamping surfaces and the mating surface for the base plate of such a tilting bearing should also be used the tie rod with such a pull made of plastic, preferably to be provided from Polyte trafluoroethylene. Such a trained The bearing is then movable in all directions and can be subjected to both compression and tension. The ones on the plastic coatings adjacent surfaces of the individual bearing parts are advantageous provided with a hard ear coating, which further reduces the frictional resistance.

The drawing shows an embodiment of a tilting bearing shown in section according to the innovation.

The tilting bearing, which is movable in all directions, consists, for example, of the base plate 1, which has a hollow ball shell la has, äie into which the spherical shell 2 is inserted. The area the hollow spherical shell la has a plastic coating 5 provided, while the mating surface 2a of the spherical shell is hard is chrome-plated.

To claim such a tilting bearing on train, the Base plate 1 clamped in place, for example by using a support ring 4 and a clamping ring 5 * which are secured by screws 6 be pulled together with the interposition of a spacer ring 7. The screws β are inserted into the concrete layer 8 in a suitable manner let in. The clamping surfaces of the base plate 1 are provided with a plastic coating 9 or 10, while the Counter surfaces 5a and 4a are hard chrome plated.

Both the base plate 1 and the spherical shell 2 are with provided a central bore through which a tie rod 11 is inserted. This tie rod is connected to a pressure washer 12 provided, which is located in a recess Ib of the base plate. The base area of this recess Ib is slightly spherical

designed and also equipped with a plastic cover IJ, while the contact surfaces of the thrust washer 12 with

is provided with a hard chrome coating.

The spherical shell 2 can be surrounded by a collar 14 in a manner known per se. The space between this collar and the individual parts of the bearing can be filled with a lubricant to protect the friction surfaces against the effects of air to protect.

Should the bearing have to be raised due to lowering of the foundation, so the camp can be underlaid with sheet metal plates or the like. The anchor bolts 6 are then longer by correspondingly Screws replaced.

Of course, the innovation is not limited to the illustrated embodiment if the bearing only displaces to run in one direction, the support ring 4, the clamping ring 5 and the spacer ring 7 is designed accordingly replaced rectangular frame.
