Scaffolding element

The invention relates to a framework for producing a framework ions serving scaffolding element with a stand, a from the arm extending in the transverse direction thereof and provided at the free end of the arm for connecting the Arms rait one end of a stand of another similar piece of armor.

With such a scaffolding element, the stand can be at Use a vertical position with the arm extends horizontally from the top of the stand.

It is the object of the invention to provide a framework element create, the structure of which is very simple and which can easily be connected to other similar scaffolding elements to to produce very different scaffolding structures.

The invention is characterized by a free end connecting part attached to the arm, which is connected to a linde des Stand of another similar frame element in engagement can be brought and opposite the arm in a longitudinal direction of the associated stand is displaceable in the parallel direction, so that the connecting part with the stand

further similar G-frame elements can be brought into or out of engagement, wherein the posts of both G-frame elements run parallel to each other, and by an alignment means, which is provided at ₌ the free end of the arm with one end of a post of another Similar G-eriistelements can be brought into engagement in order to align the uprights of the two further G-eriist elements so that they are both connected to the free end of the arm of the first-mentioned scaffold element.

Preferably, the connecting part has a sleeve, which can attack on the outside of one end of the stand of the further similar scaffolding element and the opposite to the arm which it is mounted, is displaceable in the longitudinal direction.

The alignment means preferably also has a sleeve which is guided displaceably in a similar manner.

The two sleeves are preferably used by the two Ends of a sleeve formed, which at the free end of the arm along its longitudinal axis and parallel to the longitudinal direction of the Stand from which the arm carrying the sleeve extends, is displaceable.

For example, the free end of the arm can be a guide element wear, which has the shape of a rod or a tube and runs parallel to the longitudinal axis of the stand, of from which the arm extends, the displaceable sleeve having a guide part, for example a tubular part, which is displaceable in the longitudinal direction of the guide element «, If necessary, the sliding sleeve can be in its

The maintenance of parallelism between the upright of the first-mentioned frame element and the aligned ones uprights of the further scaffolding elements can preferably be supported in that, if the uprights are vertical stand, one end of each guide element, namely the lower end, to one side, for example the upper side can hit a shoulder that is attached to the stand of the white. direct scaffolding element is provided, namely when the two Scaffolding elements are connected to one another.

The invention also includes a scaffolding structure one that consists of a large number of interconnected framework elements exists according to the previous description.

Apart from its advantageous usability in the In the manufacture of scaffolding structures of various shapes, the scaffolding element according to the invention has the following advantages on:

1. The stand can be smooth on both ends. i.e. it is not necessary to shape it so that

2. The one described above between the free end of the arm of the scaffolding element and other similar scaffolding '. Elements produced connection also serves to the adjacent ends of oppositely extending To fasten stands of other similar scaffolding elements aligned.

3 · Since the connecting part, for example the sleeve or the sleeve, is displaceable with respect to the arm, the scaffolding elements arranged in the same row, i.e. in the same horizontal row, can easily with their corresponding, initially all substantially parallel uprights are connected to one another, and the opposite ends of the uprights of the scaffolding elements of the row can all be connected to one another in alignment, without the need for the scaffolding elements to be connected in any particular way. move when the connecting part on the arm of a frame element is to be connected to the end of the stand of the further, similar frame element ₀

The free end 13 of the arm is over a guide element connected to the strut 14. The guide member 16 has the shape a short cylindrical tube and is welded to the adjacent end of the strut 14 and the free end 13 of the arm. For this purpose, the two ends are flattened, and the guide element 16 runs parallel to the stand 10. The guide element protrudes a short distance beyond the upper side of the arm 12 so that it is, for example, about 10 cm above the upper one End 11 of the stand 10 ends. The end of the guide element 16 ' carries a head 17. On the guide element 16 is.parallel to the stand 10 vertically displaceable a tubular guide part 18 stored, on one side of which a cylindrical sleeve 19 is welded, which is parallel to the guide part 18 and to Stand 10 extends so that it is arranged vertically. The bore of the sleeve 1g is slightly larger in diameter than that Outer diameter of the stand 10, so that it can freely rest on the aligned, opposite ends of the stand of two other similar scaffolding elements sits.

In the embodiment shown, ig is in the sleeve fastened in the middle between its two ends a rope part 20, which is designed as a king, the diameter of which corresponds to the outer diameter of the stator 10 and the means diametrically opposite welding points 20a "is attached, which are provided in holes I9_a in the sleeve I9 (Fig. 2). In addition, the end parts of the neck I9 serve above and below the Stop part 20 as sleeves 21 and 22, which are used to accommodate the Stand ends serve. . .

The arrangement is also made so that the neck 19 from the in Pig. 1, lower shown by solid lines Connection position can be moved into the upper position shown in Fig. 3, from which a connection can be established can. Thus, the upper end 11_a of the stand 10_a can be further similar scaffolding element can be arranged directly under the lower sleeve 22 of the sleeve and aligned with it, ^ in that the two frame elements are only horizontal to one another ■ be moved, whereupon the sleeve I9 is released so that their sleeve 22 as seen in Fig. 1, the end 1-1 et des Stand 1Oa ^ and with the upper end of the stand in Engagement is, whereby a lOja for this part of the stand Stock is created.

The head I7 is at the edge 17a near the sleeve I9 cut so that the adjacent side of the sleeve I9 can be received by it.

Upward movement of the sleeve 19 over that shown in FIG Position addition is prevented that the upper end of the guide member 18 to the underside of the head

Another advantage of the embodiment described above is that when the framework elements 9 as above are connected to each other, it is not necessary is to move the frame elements at an angle to each other to connect neighboring scaffolding elements with each other, regardless of whether they are in the same horizontal row or in a daa?

If one ^{starts with the scaffolding element having the stand 10 in the scaffolding construction shown in S 1} Ig ₀ 4, which is square in plan view, the next scaffolding element, which has the stand 1 () a when it is to be attached, is simply inserted into the Brought position shown, in which the stand 1 <Da is parallel to and precisely aligned horizontally with the otander 10. Then the sleeve 19 associated with the stand 10, which has already been raised to allow the above relative arrangement of the two frame elements (Pig. 3), is lowered without the stand 10a having to be angularly displaced with respect to the stand 10 during the connection. Thus, with the present invention, it is extremely easy to connect the various framework elements in the same row or in vertical rows.
