DE2942278A1 - Universal adjustable scaffolding wall holder - has variable length extension linking variable shape fixed to rigid anchor piece - Google Patents

Abstract

An anchor at one end, and an attachment device at the other, are incorporated in a rigid elongated retaining unit for a scaffolding frame, for anchorage in a building structure. It has an end base piece (2), with anchor, an extension (3) of selectable length, for connection with this, and scaffolding fixture element, of selectable shape, for attachment to the extension. All these parts are interconnectable by screws so as to be coaxially aligned. The base piece is the most flexurally rigid of the three.

Description

Scaffolding holder

The invention relates to an anchored in the building, elongated, rigid scaffolding holder, which has an anchor at one end part and an anchor at the other end part Has scaffolding connection device.

Such, remaining in the structure and the temporary fortification Scaffold holders used for working and protective scaffolding on the building are known.

Here, however, it is necessary to adapt to different ones Facade designs a large number of Gerflatholders with mutually different Establish, maintain and incorporate lengths and strengths in order to achieve the to obtain the required overhang length, in all cases also a Sufficient strength should be guaranteed in all cases according to DIN 4420 also safely transferred to the structure via the device holder to be able to.

The object of the invention is now to provide the multitude of previously required To reduce scaffolding holders and to increase the production, storage and assembly simplify.

The solution to this problem is characterized by the claim 1 marked features.

This has the advantage that now only one base part is produced, must be provided and installed, which corresponds to the respective requirements Extensions and scaffold fastening elements, for example head or eye bolts, can be assigned, the selection at the place of use after assembly of the Basic elements can be taken.

In addition, there is now the advantage that after the scaffold holder has been used, the extensions and scaffold fasteners can be removed from the structure.

In addition, rearrangement is also possible with the simplest of measures possible.

There is also an undisturbed, straightforward force.

The course from the scaffolding into the structure is ensured, from which, if sufficient Strength results in a relatively low cost of materials.

A design of the above-described one that is particularly favorable in terms of production technology The subject matter is disclosed in claim 2.

Claim 3 and in particular claims 4 + 5 disclose one preferred, both producible with the simplest means and extremely robust Embodiment.

Further advantageous developments of the above-described subject are disclosed in claims 6-9.

An embodiment of the invention is shown in the drawing and is described in more detail below.

They show: FIG. 1 an assembled scaffold holder in longitudinal section, FIG. 2 also seen from above.

This scaffold holder is made from a base part anchored in building 1 2 an extension 3 and a scaffold fastening element, not shown, for example a ring screw.

The base part 2 and the extension 3 are made as sleeves on their entire length of the same circular cross-sections having tube sections manufactured.

The base part 2, which has a wall thickness about twice as large as the Extension 3 has, as an anchor, has a flattened end part 4. In the latter is a hole 5 for cornering a cross bar or for attaching it to the structural reinforcement arranged.

In the other end part of the base part 2 is a coaxially extending Threaded hole 6 cut. In the latter, the one of the threaded hole 6 is corresponding Extension 3 having external thread zone 7 is screwed in.

At the free end of the extension 3 is opposite in diameter the latter reduced sleeve part 8 integrally formed, in which a threaded hole 9 for Screwing in the one of the threaded hole 9, not shown, corresponding Threaded pin having scaffold attachment is arranged steep. The nominal diameter the threaded hole 9 is about a third smaller than that of the threaded hole 6th

The screw connections can use known means against unintentional Loosening be secured.

In those cases where the extension 3 and the scaffold fastening element can permanently remain on the mounted base part, the screw connections be secured by means of spot welds.

The greatest length of an extension 3, for example 120 mm, corresponds about 2/3 the length of the base part 2, which is about half of its entire length is inextricably embedded in the structure 1.

In the extension 3 a transverse bore 10 is also arranged through a rod for screwing the extension into the threaded hole 6 of the base part 2 can be inserted through.

All new items disclosed in the description and / or drawing and combination features are considered essential to the invention.
