"Method of assembling a scaffolding, yoke, for use in this method and using this procedure assembled scaffolding or

Part of the same "

The Ürfindung relates primarily to a method for assembling a scaffolding using " dung extending in two directions, each with at least one stand and at least one rigid associated beams of Sbapeljoche provided, which are set up in at least one vertical plane, the uprights being more consecutive to one another in the vertical direction Yokes are connected by coupling ends that can be inserted in the longitudinal direction of the upright, and scaffolding levers by clamping elements acting on the carrier be attached to these.

In the known assembly method of this type the yokes are usually set up at an angle to the façade. The rooms measured along the facade between

see neighboring ben yokes may then with regard to the supporting women of the scaffolding board between these yokes are not chosen too large, so that a relatively large number of yokes is required. In addition, it makes difficulties in practice, the intermediate supports, on which the planks of the scaffolding board are to rest, and which supports in general too are formed by scaffolding levers, to be installed at exactly the same height. If the height of these supports is unequal the G-decking does not provide any security. In addition, there are many different, elements often provided with complex and complex connecting and fastening elements required, especially with regard to the required rigidity of the completed framework in Horizontally along the facade,

According to other known assembly methods for such scaffolding, so-called scaffolding towers are produced from yokes that are nested in one another in two mutually perpendicular planes. As far as the distance between neighboring towers is concerned, the above problem is also noticeable. In addition, the stiffeners, such as struts or intermediate supports in the yokes set up across the facade, interfere with the traffic over the scaffolding boards and make them unsafe.

The subject of the invention is now a / experienced the type mentioned at the beginning, in which the above and similar disadvantages of the known methods are avoided. The invention is based on the knowledge how with the smallest number of different elements one in primarily in the horizontal direction the facade is

long stiff scaffolding structure can be assembled with a minimum of material and with relatively low manpower due to significant limitation of the number of people involved in this assembly bringing connections.

For this purpose, such a method of the invention according to characterized in that corresponding support associated with-each other in said vertical plane horizontal auffolgenden yokes are coupled to each other directly or indirectly in escape by _v initially to be coupled ends for mutual overlapping of are designed complementary in the longitudinal direction of the carrier, moved transversely to this longitudinal direction until they touch one another and then clamped to one another by the fastening element of a scaffold lever laid at this point.

Arrange the beams of adjacent yokes in alignment with one another and couple conditionally if a scaffold is in front a facade is to be built that said vertical plane runs practically parallel to the facade. In most cases, the stacking yokes are of course more parallel in two of these Vertical planes are stacked so that when the scaffold lever is attached by its fastening elements on the beams to be coupled in each of these two vertical planes the coupling of two pairs of adjacent ones Support elements in these two vertical planes is completed

Effect of the fastening organs on the girder connections sufficient stability of the assembled scaffolding in the transverse direction to the facade. I ¹ Ur these scaffold levers can be used in the normal way those of the previously usual type.

Particularly useful in the method according to the invention is the particularly simple design of the yokes, which can practically all be of the same type. Possibly, for the purpose of indirect coupling, the can be aligned with one another to be coupled main beams also intermediate supports are used, which in this case with the each formed complementary to the main beam ends Ends are provided.

The invention also relates to a yoke that is used in the "implementation of the above method is to be used and is designed in such a way that there is at least one stand and a few t-ens one has rigidly connected girders. According to the invention, such a yoke is characterized in more detail: that the carrier ends are provided with longitudinally extending tabs that connect to each other should overlap with their complementary ends.

In a more detailed elaboration according to the invention, the tab surface intended for clamping can also be used with a pin or jib protruding from it in the transverse direction and / or a complementary one be provided with a formed recess

According to the invention can also be used for clamping certain tab surfaces essentially transversely to the

909831/0276

Ständerlängsriehtung run, with the tab recess also across the direction of insertion of the complementary pin or cam is formed accessible laterally this pin or cam.

According to the invention, the yoke can further contain only one stand and the support ends can be complementary be designed to each other, in which case the tab with the pin or cam protruding from it is at a relatively small distance from the stand with respect to the other tabs.

Finally, the invention also relates to a compiled using the above method Framework or part of it.

The invention will now be made with reference to the drawing, in which, for example, part of a stacking frame reproduced according to the invention with some details is explained in more detail.

Show it:

1 shows a side view of three stacking frame yokes coupled next to one another in one plane by means of carrier ends inserted into one another;

2, on an enlarged scale, the ends to be coupled of adjacent girders spaced one above the other with associated end views;

3 shows a plan view of the left end of the support of the yokes drawn on the right in FIG

ig. ^ _ 4 a perspective view of an advantageous 909831 / 0276

th embodiment of the carrier end with special Design of the tab with a cam and a receiving slot.

According to the drawing, each yoke consists of one in the transverse profile round tubular stand 1 and a carrier 2 extending at an angle thereto, which consists of two equidistant Hurry roaring. 2 a and 2b or 2c of the same profile as the stand. These pipe parts are in ■ the one from Pig. 1 evident way at 3 or 4 with

^ welded to the stand so that the carrier and Stand axes intersect. The stand 1 is provided at the top with a pin 5, over which the lower Sleeve end 6 of a corresponding yoke to be arranged over it fits in the same center so that it can be pushed on. carrier 1 and stand 2 are apart from the one in FIG. 1 right yoke firmly connected by a strut 7 welded to it at both ends. The one in Pig. 1 Left support parts 2a have a short length in relation to the right support part 2b, the support part 2c of the in Pig. 1 right end yoke is even shorter. The one in Pig. 1 left beam ends are near of the stator 1 of the relevant yoke with an end

W. tab 8 provided. This was formed in that an upper pipe part was removed from the free end of the support part 2a over a certain length, in such a way that a then welded sheet 9 (see Fig. 2) its top and the horizontal center plane of the pipe part 2a run flush.

The sheet 9 has a central rectangular opening 10.

The one in Pig. 1 have right ends of the support parts 2b

a complementary shaped tab 11, i. this has a downwardly protruding pin 13 instead of a recess, which when lowering the relevant Yoke in relation to that in Pig. 1 on the right next yoke, whereby the receiving sleeve 6 also has a the pin 5 shown, corresponding pin of a yoke arranged under the relevant yoke pushes, received in the opening 10 of the tab 8 at the left end of the carrier of the next on the right can be.

With 14 and 15 are in Mg. 1 scaffold levers with which clamping members 16 and 17 for fastening the relevant scaffolding lever and are welded to the girders 2. Each clamping member 17 is fixed in Clamping position also the inserted tab connection of the tabs 11 and 8 of the adjacent yokes 1.

As a result of the unequal length of the support parts 2a and 2b, the push-in connection is due to the weight of the yoke the tab 11 with the tab 8 already somewhat against sliding apart before fastening the clamping members 17 secured.

The scaffolding levers 14 and 15 are firmly anchored in a proper manner in the facade of a building and thereby give the framework the necessary stability in the transverse direction to the Zeiohnungeplane.

Fig. 3 shows another modification of a tab 18, similar to the tab 8, but with open access 21, which adjoins the opening 20 in the sheet metal 19 which is otherwise the same as the sheet metal 9, whereby this opening 20 is also accessible from the side of the pin 13,
