Tensioning dowel that can be used in buildings for fastening and carrying objects, especially for carrying heating radiators

The invention relates to a clamping dowel which can be used in buildings for fastening and carrying objects, in particular for carrying heating radiators.

The object of the invention is to create a clamping dowel that allows easy and convenient adjustment between the building and the heating radiator. Such a tensioning dowel should be simple in execution and thereby be inexpensive to manufacture.

According to the invention this is achieved in that on the bolt between its head part and the a tapered part provided with a thread at the rear one side partially and on the opposite side completely slotted pipe piece is arranged, which on his rear parts opposite, running out to the ends, has deeply drawn embossings, against which when turning

of the screw bolt slides along the cone part and thereby pushes the rear parts of the pipe section outward, wherein the webs on the cone part secure the cone part against being entrained when turning the screw bolt.

In a further embodiment, the broad side of the conical part is square-shaped, which slides with its opposite corners when turning the screw bolt along the embossments in the pipe section and thereby pushes the ends of the pipe section outward, and that via the other opposite corners by lateral contact with the ends of the pipe section, the conical part is secured against entrainment when the screw bolt is turned. _:

With the clamping dowel designed according to the invention:

I is any required change in the distance between that! The tensioning dowel used in the building and the part received on the front of this J is possible because when the | Screw bolt, the slotted pipe piece goes back to its original shape due to the resilient state and can thus ' easily be moved to the desired distance. Due to this nature, tensioning dowels that have already been used can easily be removed on request without damage and reused at another point in the structure. It can be supplied in any desired length and can therefore be used by all builders.

and the cone part 5 superimposed pipe section 6 ″ has on his rear parts 8 and 9 opposite, tapering towards the end, deep-drawn embossings 10 and 11. When turning the Screw bolt 1, the conical part 5 guided in the pipe section 6 slides along the two embossments 10 and 11 and presses while the rear parts 8 and 9 of the pipe section 6 to the outside. The conical part 5 engaging in the pipe section 6 has opposite, engaging in the slots of the pipe section 6 webs 14 and 15. Through these webs 14 and 15, the when the screw bolt 1 is turned laterally against the rear parts 8 and 9 of the pipe section 6, the conical part becomes 5 secured against being taken away.

In the embodiment according to FIGS. 4 to 7, the broad side 8 of the conical part 19 is square. With its opposite corners 20 and 21 it presses when turning the screw bolt 22 along the embossments 23 and the ends 25 and 26 of the pipe section 17 to the outside. The opposite corners 27 and 28 lie against the side Ends 25 and 26 of the pipe section 17 and prevent dadtsrch the entrainment of the conical part 19 when turning the screw bolt 22. The support part 3 used in the clamping dowel and the one in Both designs on the screw bolt 1 and 22 by means of thread superimposed conical part 5 and 19 are advantageously made of plastic.

Claims (2)

Protection claims: 1. Tensioning dowels that can be used in buildings for fastening and carrying objects, in particular for carrying heating radiators, in the one on a screw bolt between the front support part and the rear on the threaded part Conical part a pipe section slotted on both sides is arranged, characterized in that on the rear parts (8 and 9) of the pipe section (6) opposite deep-drawn embossments (10 and 11) tapering towards the ends are present along which the conical part (5) slides when the screw bolt (1) is turned and the rear parts (8 and 9) of the pipe section (6) pushes outwards, with the on the cone part (5) the existing webs (14 and 15) secure the conical part (5) against entrainment when turning the screw jack (1). 2. Clamping dowel according to claim 1, characterized in »that the broad side (18) of the conical part (19) is square-shaped and this with its opposite corners (20 and 21) when turning the screw bolt (22) along the embossings (23 and 24) slides and thereby pushes the ends (25 and 26) of the pipe section (17) outwards and the other opposite corners (27 and 2G) by lateral application to the ends (25 and 26) of the pipe section (17) the cone part (19) at Turning the screw bolt (1) secures against entrainment.
