Registrant: Rolf Schatz, 7238 Oberndorf / N-Boll Support base, especially for pipe clamps

The innovation relates to a support base, especially for pipe clamps consisting of two metal plates, which are parallel to each other through an intermediate layer made of elastic material, in particular technical rubber are kept at a distance from one another, wherein a metal plate is provided with at least one threaded bushing.

There is already a clamping plate for pipe clamps known (DE-GM 76 12 444) in which the two metal plates on one of technical Rubber existing intermediate layer are vulcanized. Such clamps The task of plates or support bases for pipe clamps is to dampen vibrations.

In these known clamping plates, which are exclusively by material connection are connected to the intermediate layer, there is a risk that the metal plates from the elastic intermediate layer in particular all fine in the case of prolonged occurrence of larger vibrations Loosen borrowed, especially if these vibrations are directed transversely to the base and surface of the clamping plate or the support base.

The innovation is based on the task of an improved support base of the type mentioned at the outset, in which the danger

Further advantageous design features are the subject of Claims 3, 4 and 5.

On the basis of the drawing, an embodiment is now shown below the innovation explained in more detail. It shows: FIG. 1 a support base in a perspective view Fig. 2 is a section through a threaded bushing of the upper metal plate.

The support base 1 shown in the drawing consists of an upper metal plate 2 and a lower metal plate 3 and an elastic intermediate layer 4, which can consist of natural or synthetic rubber or a similar vibration-damping material. The lower base plate 3 is provided with two tab-like extensions 5 and 6, each of which has a through hole 7 for fastening screws. In addition, the lower metal plate is provided with longitudinal, trapezoidal-inclined wall elements 8 and 9 which are in contact with the likewise trapezoidal-inclined side surfaces 10 and 11 of the intermediate layer L. The upper metal plate 2 also has lateral, trapezoidal inclined edge strips 12 and 13 immersed in the intermediate layer U. The arrangement is such that the inner longitudinal delimiting edges \ L and 15 of the wall elements 8 and 9 have a smaller distance a from one another than the outer longitudinal delimiting edges 16 and 17 of the edge strips 12 and 13 and that the distance

between the edge strips 12 and 13 on the one hand and the wall elements 8 and 9 on the other hand is the same size on both sides and each filled by the intermediate layer. The upper metal plate 2, which is provided with two threaded sockets 18 and 19, which, as can be seen from FIG. 2, are riveted into corresponding bores 20 and are used to receive fastening screws. which a pipe clamp can be attached to the support base 1. It can be seen from the drawing that the angles of inclination of the inclined edge strips 12 and 13 and the side inclined wall elements 8 and 9 are at least approximately the same, that the metal plate 2 is centered between the wall elements 8 and 9 and flush with the upper delimiting edges IA and 15 is arranged. In this arrangement there is a positive connection between the intermediate layer A and the two metal plates 2 and 3 as well as between the two metal plates 2 and 3 among themselves, so that an additional material connection between the intermediate layer A and the two metal plates 2 and 3 is not necessarily required, even if it is appropriate. It can be completely sufficient if, by heating in sections at certain points of the two metal plates 2 and 3, a bond is created by vulcanization. Instead it would also be thinkable. to produce this material connection with the help of an adhesive.

A particularly favorable production results from the fact that the elastic intermediate layer U consists of a prefabricated rod pro-

files with the two inclined side surfaces 10 and 11 as well as with two inclined longitudinal grooves 21 and 22 to accommodate the edge strips 12 and 13 consists, so that the correspondingly cut pieces as an intermediate layer Λ by pushing together in the longitudinal direction with the two metal plates 2 and 3 can each be joined together to form a support base 1 shown in FIG.
