DE2362008A1 - Temp.-variation-compensating elastic ceiling support bearing - with press members fixed in hard foamed material and protruding from it - Google Patents

Abstract

The elastic bearing, esp. for use under ceilings, and designed to compensate for movements relative to the substructure resulting from shrinkage or dimensional variation caused by fluctuations in temperature, comprises an elastomer body embedded in a hollow body. A number of pressure members are mounted close together, fixed into a layer of hard foamed material, from which they project upwards and downwards. Spherical and cylindrical pressure members may be form-locked in fitting barrel-shaped recesses in the foamed material, or they may have two or more concave lateral surfaces. Compensation for movement is enhanced, and resultant tensions in the bearing structure are reduced, with an easily installed mounting.

Elastic construction bearings, especially for ceilings

The invention relates to an elastic structural bearing, in particular to a support for ceilings, the caused by shrinkage or change in size Compensates and compensates for relative movements in relation to the substructure that occur in temperature fluctuations consists essentially of an elastomer body embedded in a hollow body.

Except for liner, the fi ^; For these purposes can only be used with careful preparation of the film bed, it is known to use strip-shaped elastomer bearings that compensate for the relative movements by means of shear deformation. On both sides of the strip-shaped elastomer bearing "filling bodies are arranged to have not interfere with the effectiveness of the strip. The shear deformation forces such strips are very high so that correspondingly high forces acting on the retaining walls, whereby cracks and even flaking on · upper edge of the masonry arise ₀ Because the movements

in the ceiling not just perpendicular to the edges but also occur in parallel, ι & PB 2 0 0 add up Transverse tensile forces and load the supporting structure. With all building forms, which often only occur locally, the entire camp is involved in the tensioning process.

The object of the present invention is to provide a rough bearing to create that compensates for the movements that occur to a far better degree and consequently those in the l'rag constructions occurring tensions effectively reduced. In addition, the warehouse should be easy to relocate, and it should also largely rule out errors on the construction site itself.

According to the invention, the task in construction camps is the initially mentioned type solved in that a plurality of pressure bodies arranged next to one another in a rigid foam, from this is attached protruding downwards and upwards. D ^ e embedded in the rigid foam Pressure bodies that protrude upwards and downwards are essentially the same in all directions deformable. They are apt to be independent of each other to absorb locally occurring forces and deformations and by means of shear-soft elastic To break down giving in.

attached to foam, either in such a way that round, thus spherical and cylindrical pressure bodies in matching barrel-shaped recesses in the rigid foam with a positive fit intervene or that pressure body with at least? concave side surfaces in matching recesses of the Rigid foam are positively attached »

The pressure bodies should preferably be individual bodies, which, however, under certain circumstances can be combined to form a group.

are united and consist of a sf ck. These groups then form pressure bodies, which again contain cavities have and are themselves capable of functioning independently or in a manner that cannot be influenced by the surrounding rigid foam.

The pressure bodies or their groups are advantageously carried in one or more rows under the edge of the Arranged in the ceiling, as they create constant moments in the ceiling. The top and bottom made of rigid foam protruding part of the pressure body will expediently have a total height that corresponds to the static Load of the supported component essentially corresponds to the spring deflection generated. Under load, the rigid foam fulfills is precisely the spaces adjacent to the pressurized bodies but not involved in lifting the load.

A particularly suitable form of the pressure body is seen in the fact that 'Mo separated parts of a profile and with

their profile axis are arranged parallel to the edge of the supported ceiling at a distance from one another. Advantageous the profile consists of three concave side surfaces provided between cover plates Webs. These webs also retain significant relative movement between the substructure and cover a support body lying essentially vertically, because the material consists of the widening at the top Webs is still almost fully load-bearing even with inclined webs.

An embodiment of the subject matter of the invention is illustrated by the drawing. Show it

Pig. 1 is a side view of a pressure hull

with a strip of embedding ^ foam,

Fig. 2 is a plan view of the object according to. 1.

A pressure body 1 consists of a cover plate 2 and a base plate 3, between which webs 4 are arranged. The profile formed in this way is injected in one piece and continuously from a chloroprene and cut into individual pressure sections. The upper and lower surface of the hemmed ^n: ckes 1 have grooves 4,

in order to have a connection to the adjacent ones that is as smooth as possible To have components.

The webs 4 are limited by barrel-shaped cavities, so that when they are inclined they still contain about a column of the same cross-section.

As FIG. 2 shows, the pressure body 1 in supernatants from each other embedded in a Schaumstoffkröper 5, wherein the embedding is carried out ^form-r SSIG. The distance between two pressure hulls lying next to one another is somewhat larger than the width of a pressure hull, since the profile is somewhat harder in its axial direction than perpendicular to it.

The illustrated profile can also have a different cross-section

if only single pillars or a group of pillars or bars are always present. The pressure hull can can also be spherical, cylindrical or prismatic with a vertical axis if they are spaced apart from each other in the Foam 5 are embedded in rows.
