' SHEET 2 0F 2 BEARING FOR SUPPORT OF ROOFING TILES The invention relates to a bearing for the support of roofing slabs at a spacing above the roof, such a bearing consisting of a base body laid upon the roof and a slab support member resting on said base body, which can be secured in a specific vertical position by rotating a threaded coupling arranged between said base body and slab support.
Bearings for the support of roofing slabs, having a slab support which is vertically adjustable, are known. A bearing is also already proposed in which the base is designed like abracket and the slab support has, on the underside, a threaded bolt which can be inserted through a hole in the bracket and can be fastened to the bracket by means of one or more nuts.
However, as practical experience has shown, such a device has the disadvantage that the vertical adjustability, more especially :if roofing slabs are already in place on the slab supports, is relatively complicated, since first of all the nuts holding the threaded bolts have to be released, then the slab support has to be raised and be locked by retightening the nuts. This is extremely difficult to accomplish especially with roofing slabs in place.
An object of the invention is, therefore, to provide a bearing, of the type mentioned hereinbefore, in which the vertical adjustability can be carried out simply, even with roofing slabs in place. It is an additional object that such vertical adjustment should be able to be carried out rapidly.
Accordingly, the invention provides a bearing for the support of roofing slabs is proposed which is characterised in that a threaded coupling means is designed as a threaded bolt having two oppositely directed screw threaded segments, of which one screw threaded segment can be screwed into a corresponding female thread in the base body and the other screw segment can be screwed into a corresponding female thread in the slab support.
Advantageously, arranged laterally on the slab support is a fork which embraces a locking pin which is fixed on the base body, and which is perpendicularly slidable in relation to the base body. Advantageously, the fork has guide lugs which extend over the lower edge of the slab support.
The slab support can alternatively by securely inset into the roofing slab.
In accordance with a further development of the invention, arranged on the threaded bolt, between the two oppositely directed thread sections, is a peripherally toothed actuation wheel and an abutment for a pin which rotates the actuation wheel is provided in the base body.
In order to be able to compensate for fairlylarge differences in height, the base body can be placed onto a pedestal which is provided with a boundary flange.
The invention will now be more particularly described, by way of example with reference to the accompanying drawings, wherein:
FIG. 1 is a top view of a support bearing in accordance with the invention;
FIG. 2 is a partly sectional side view of the bearing of FIG. I;
FIG. 3 shows a threaded bolt having two oppositely directed thread sections;
FIG. 4 shows a slab support; and
FIG. 5 is a partial sectional view showing a slab support inserted into a roofing slab.
The bearing in accordance with the invention consists of a base body 1, which has a base plate 2 which carries upwardly projecting limiting pins 3, which are spaced apart and mounting supports 4, which are each provided with an internal screw thread. A threaded bolt 5, which has two thread sections 6 and 7 (FIG. 3) with oppositely directed threads can be screwed into each of the mounting supports 4. Arranged between the thread sections 6 and 7 on the bolt 5 is a peripherally toothed actuation wheel 8. Screwed onto the upper thread 7 of the bolt 5 is a slab-support 9, which has a corresponding internal thread. Situated laterally on the slab support 9 is a fork 10, which has guide lugs 11 which extend over the lower edge of the slab support.
The fork embraces a perpendicularly upwardly projecting locking pin 12 which is arranged on the base plate 2 of the base body 1 and in relation to which the fork is perpendicularly shiftable when the slab support 9 is raised or lowered.
The actuation wheel 8 has on its periphery teeth 13. An abutment 14 is provided below the teeth in the base body 1, so that the actuation wheel 8 can be rotated with the aid of a pin which is introduced into one of the tooth-gaps l5 and which pin is braced on an abutment 14. By this means it is possible to rotate the actuation wheel 8 even when the roofing slabs are already in place on the slab supports 9, since there remains between the adjacent slabs, as a result of the limiting pins 3, a narrow gap through which the pin 12 can be pushed as far as the base of the abutment 14.
By virtue of the design of the bolt 5 with two oppositely directed thread sections, upon rotation of the actuation wheel 3 and therewith of the bolt 5, the bolt 5 is screwed in to or out of the female thread of the base body 1 and the female thread of the slab support 9, whereby a perpendicular travel is achieved which is twice as long than would be possible with a single thread. The locking pin 12 in conjunction with the fork l0 ensures that, upon the rotation of the actuation wheel 8, the slab support does not co-rotate.
If, as shown in FIG. 5, the slab support is connected securely to the roofing slab 18, it is naturally not necessary to provide a fork or a locking pin, since in this case the roofing slab itself prevents any co-rotation.
As FIG. 2 shows, a pedestal 16 can be provided, onto which the base body 1 is placed, if it is necessary to provide for greater compensation in elevation. The pedestal 16 is provided with an edge flange which prevents the base body from slipping from the pedestal.

A bearing for the support of roofing slabs at a spacing above a roof, consisting of a base body laid on the roof, and a slab support resting on said base body, said support being securable in a specific position in the vertical sense by rotating a threaded coupling which is arranged between said base body and said slab support, said threaded coupling is a screw-threaded bolt having two oppositely directed thread sections, of which one thread section can be screwed into a corresponding female thread in the base body and the other thread section can be screwed into a corresponding female thread in the slab support.
