DE7624735U1 - CLAMPING DEVICE FOR WALL ELEMENTS FOR FASTENING ROBUSTA WALL SUPPORTS ON THE TOP - Google Patents

Description

The invention relates to a clamping device consisting of a threaded rod at one end. . a, im., Juer cut rectangular clamping block is fixedly mounted, and a further, rectangular in cross-section, clamping block, _r, together with a S annmutter on dei * threaded rod are movably arranged wherein the threaded rod projects through a bearing plate and the clamping nut on the one hand and the Terminal blocks, on the other hand, are located on the opposite side of the support plate.

Prefabricated elements in building construction, in particular / and elements, must be aligned with their mounting and -to your final composite with the subsequent elements. D ^ it is mostly done by means of supports that can withstand tension and pressure are - hereinafter referred to as "tension and pressure supports". These Tension and pressure supports must be frictionally connected to the relevant one Wall element to be attached.

Two methods of fastening are known for this:

a) a screw connection on the f / and element

b) by means of so-called K ^ emmzwingen.

The screw connection takes place with embedded in the wall element Üoenmuffen, threaded sleeves or similar, enabling a screw connection built-in parts.

These structural elements are lost, that is, they remain in the wall element and - in the case of a cone - only serve one purpose, ^{to enable the assembly by means of z} uß- and pressure sockets,

Shell parts made of ordinary steel are made later in exposed concrete noticeable through unsightly rust spots. The use of stainless Built-in parts is uneconomical due to the fact that they are lost and only have a puncture when contiguous. Plastic components are unsuitable for high loads.

K] emmzwingen correspond ir. Their structure and their puncture to the, z. ?>. in the common “screw clamps”. They only have larger pee areas and an additional attachment option for 2 '' Uf: - and pressure supports.

Ui ''; v / earth is placed over the upper edge of the relevant wall element and by means of their "screw pliers"

1 ^ r disadvantage is that as long as it remains psi V / andelement is necessary, no further work can be carried out that are ± v: connection with the Gburj-run of the wall element in question. .. For example, it is not possible to attach a prefabricated ceiling element as long as the Kleninz clamp is still on the upper edge of the associated. <ai ·. iel is appropriate.

The -, rfincumr underlies the task, avoiding the disadvantages mentioned above, a non-positive connection between to create the tension and compression support and the relevant wall element.

The task vurc-e according to the invention, when using a clamping device, consisting of a threaded rod at one end of which a ..Ie: imstein is firmly attached and another K ^ emmstein, together with a chip chuck. movably arranged on the threaded rod are -, solved in that on the platen there is a U-shaped Shoe. with a through hole through the legs of the U's is located.

In order to achieve the desired clamping effect, the has a handle on the handle firmly attached terminal block two flat side surfaces tapering in the direction of the threaded rod.

The advantage achieved with the invention is in particular that no (lost) mounting parts have in the wall element to be mounted be present, but only a suitable A _u ssparung and that the above known of the relevant wall element for further operations remains freely accessible.

In one embodiment, the invention is detailed below described.

It shows:

Fig .: 1 shows a cross-section through a clamping device in its position of use

Pig.:2 and 2a the clamping system by means of a trapezoidal terminal block

Pig.:3 and 3a the clamping system by means of a spherical terminal block i'ig .: 4 the interaction of the two terminal blocks

Pig.1 shows a cross section through a clamping device in its Position of use. The prefabricated wall element is marked with the reference number 1. The upper end of a tension and compression support is marked with the prefix 2. A screw (3) connects the tension and compression support with a shoe with a U-shaped cross-section (4). This is attached to a support plate (5) in order to achieve a larger contact surface. Through the upper part of the base the shoe (3) and the support plate (5) has a through-hole

The mean depth of this through hole is preferably located exactly at the point where an extension of the axis of the tension and compression support, if this is at 45 ° to the wall element, the The axis of the through-hole would intersect. This will be optimal Balance of power achieved

Through the through bore, the threaded rod passing (6) .They is connected at its one end bent to form a handle, A _n its other end is fixedly attached a Kiemmstein (7) "The Kiemmstein designated by the reference numeral 8 is freely on the threaded rod beweglich.Die Reference number 9 denotes a clamping nut which is required to clamp the system.

The Kiemmstein marked with the reference number 7 is inserted as described in Fig. 2 and 2a and clamped by means of the clamping nut (see reference number 9 in Fig. 1). It absorbs the axial forces. As already mentioned, the terminal block with the reference number 8 sits "movably on the threaded rod (6). and transfers it to the wall element. It can either have a rectangular or, as in the present exemplary embodiment, a trapezoidal longitudinal section _{or the like}
