The invention is a special embodiment of a connection clip with which the crossing pipes of scaffolding can be connected particularly quickly but also with the greatest possible security. Up to now, clamps that are closed by screws have mostly been used for this purpose Need to become. There are considerable drawbacks to the use of visions · Wrenches must be used. »The screws can rust up in their socket threads while the scaffolding is in use or loosen if they are well greased. Simple screws or cutters are easily lost, or, but the threads of captive secured ropes can only be greased with difficulty · Most of the time the clamping achieved is punctiform, which does not offer sufficient security «or the number grows with the increased security asx screw imd joints to 3 · & «* ^ l & zel * ¹ « * ¹ clamp.

Since the disadvantages of the screws are far more significant than the advantage that the clamps can be attached to any point of the drill, the invention is based on the basic idea of avoiding the use of screws completely on the one hand, and using drill holes on the other hand have adequate spacing of transverse holes for a stud bolt connection.

Jfach dex invention, the special purpose, reached by said means a rapid operation "and reliable connection su, old solved a connection clamp that kasnter in be" way is to the one Boppelsattelstück to insert the Drill, in which a semi-holes for inserting for the socket pin traversing the drilling; indicative of the object ά ^ τ invention is that the bolt a (suitably bulky as a handle formed) radially extending approach has, which is held in the use position by the second drilling behind a mounted on the saddle piece securing nose.

This solves the problem. Pushing in the bolt quickly and firmly connects the clamp to the one drill (and preferably to the vertical drill). Securing the bolt is effortless and automatic, because the bolt connection can only be released after the second pipe has been removed.If the bolt shoulder has not been pushed behind the locking nose, the drill inserted in the second saddle piece pushes it into the correct position by itself .

For a more detailed explanation of the basic idea of the invention and for the representation of further details is in the drawing a preferred AusungsforrB shown the connection clamp namely shows

Fig _# l) a side view,

AVb.2) a front view

Fig. 3) a floor plan of the clamp,

In the example, a sheet-steel-made shape is chosen.The double-sided ice cream consists of the two U-shaped bent pieces a and b, which are connected to one another by welding When establishing the connection, the saddle piece a is first pushed over the hole c so that the holes e in the saddle piece coincide with a hole in the vertical tube e, and the bolt f is then pushed through the holes as a handle serves here d «x angled approach g of the bolt» Subsequently, the drill d is inserted into the second saddle b. This is only possible if the handle g engages behind the securing lug h, which is formed by a bend of one leg of the saddle post a «The bolt f can be permanently connected to the saddle part by a chain i ·

The described simple and quick type of connection with simultaneous automatic securing is of course not applicable for the attachment of the second ear tube d in. The sleeve, since this tube is inserted last, so it cannot be secured by a later inserted drill this second tube is also not required, then with the horizontally lying tube, a vertical socket pin would not easily loosen. In the connection clip according to the invention, however, a special device is also created for holding the second pipe d, which ensures simple and fast work with full security of the connection and with a minimum number of moving parts.As can be seen from the drawing, the in Rohrbehrung the corresponding engaging pin fixed k and "b rigidly connected to the saddle EOHR d is thus so inserted in aen saddle that one of its bolt holes k encompasses" in this position then the rotatable plate in which m in Fig.l position shown swiveled. The pivot pin η for this leash marriage is arranged in such a way that the lug can be rotated by 180 ° to lift the ear out of the saddle b. This means that the securing part ο of the flap is larger than the opposite file, so that gravity already protects the flap against unintentional release of the ear. Here, too, the fastest conceivable establishment of the connection is possible, and full security against unintentional loosening is achieved with the simplest means.

FIG. 4 shows a schematic view of a scaffolding created with the connection clamps according to the invention. In the example, the front part of the scaffolding consists of 4 standing poles ρ and the 3 horizontal spreader bars q, _o Diagonal connections r or s are used for stiffening

Claims (2)

Hetzriegeln t connected to each other, only a few of which are indicated in Fig. 4. So far, only the connection clamps u have been described, which are used to connect the upright rods ρ and the stretching rods q. serve each other.It goes without saying that connecting clamps according to the invention can also be used to connect to the diagonals, in which case the connection between the saddle pieces a and b is not made at right angles, but either rigidly at the angle provided for the diagonals or rotatable so that the Any angle can be selected for the diagonals if the angle for the diagonals is 45 °, it should be noted that the distance between the holes in the tubes used for the diagonals must be different from that in the other bores This is not essential Disadvantage, because you can choose a smaller cross-section for the slightly less stressed diagonal pipes and then drill this hole with the changed filing. But nothing stands in the way of providing a number of normal pipes with additional bores for use as diagonals, since the integer multiples of the root of 2 happen to have the property of not coming dangerously close to whole numbers in the areas in question · Furthermore, it is also possible to use the diagonal pipes with the same hole pitch as the other holes, whereby the angle must then be selected according to the ratio 3: 4, since the whole number 5 results for the length of the diagonal. An example of this is shown for the diagonal r in Figure 4. It is assumed here that in the case of the pipes ρ and q the connecting clamp is arranged at every third bore. In any case, it follows that the necessity of attaching diagonals cannot result in any difficulties for the applicability of the connecting clip according to the invention. However, the use of tubes with evenly spaced holes has the particular advantage that the attachment of the net bars is particularly simple, because these net bars can be easily and securely connected to the scaffolding nets at the unused holes between two clamp connections using simple pins, as shown schematically in Figure 5.
