DE10143625C2 - Reduction system for scaffold couplings - Google Patents

Description

The invention relates to a reducing system for scaffold couplings.

State of the art

C from the DE-brochure "Layher flash scaffolding system" output 2/4/96 Page 14 of Fa. Layher, Eibensbach are known so-called scaffold couplings. These consist of drop-forged steel and have a screw cap. These so-called reducing couplings are high in cost and can only be used for specific problems.

It is also from DE 44 39 430 A1 a scaffold coupling with a Connection shell and a folding half-shell known, the shells over a Connection joint are connected. This joint has one inner eye and two Außenösen. Stop lugs are formed on the outer eyelets, which are located in free spaces can move and strike the stop surfaces.

Most scaffolders bind in case of inaccuracies in fit. B. railings by means of a Ropes or binding wire to the frame. Of course, this only offers one insufficient strength of the fixed object (railing).

task

The invention has for its object to avoid the disadvantages mentioned and an inexpensive and universal reducing system for To create scaffold couplings.

solution

The task is solved in that the reducing system consists of two shells one exists in the axial direction halved circular cylinder, the shells for Reduction of the inner diameter of the scaffold coupling in the two Coupling clamps are inserted, the to achieve a game Insert trays are cut to a little less than a semicircle.  

Advantages of the invention

The insert trays are inexpensive to manufacture and thus also in Purchase, they offer the possibility of any existing coupling to make a reducing clutch and again a normal clutch.

This makes the inserts more economical and flexible than existing ones Solutions. They also offer greater security than that Use of knitting or tie wire.

According to an advantageous embodiment of the invention, the insert trays are made of Manufactured iron and galvanized if necessary.

The invention is explained in more detail below on the basis of exemplary embodiments.

It shows:

Fig. 1 shows the representation of first insert trays

Fig. 2 shows the representation of further inserts.

The insert cups of FIG. 1 are depicted in a sectional view and have an outside diameter (A) of 48.3 mm. The inside diameter (B) is 33.7 mm. These insert trays are particularly suitable for reducing standard or rotary couplings already on the market (e.g. from Layher, Plettac, Rux, Thyssen-Hünnebeck, Ernst, Bauman, ASCQ and other suppliers) The inside radius of the coupling can be reduced from a 48.3 mm tube (e.g. frame) to a 33.7 mm tube (e.g. crash railing). The insert trays are therefore very flexible and can also be used in so-called special scaffolding. The purchase of a further reducing coupling can be omitted with the help of the insert shells.

Fig. 2 shows a further variant of an insert tray. The inside diameter (D) is 33.7 mm or 38.3 mm (E) while the outside diameter (F) is 48.7 mm. This variant shows that all scaffold couplings can be reduced to the desired size.

Claims (2)

1. Reduction system for scaffold couplings, consisting of two shells one in Halved circular cylinder axis to reduce the Inside diameter of the scaffold coupling in the two coupling clamps be inserted, with the insert trays on something to achieve a game are cut less than a semicircle. 2. Reduction system according to claim 1, characterized in that the Inlay trays are made of iron and are galvanized if necessary.
