Technical Field

The invention relates to a plug-in connection for a frame element of a scaffolding that can be layered.

Background

Such frame parts are mainly used for building the required under-frame when building foundations for floor forms consisting of a small number of components. For this purpose, the frame elements must be able to be stacked on one another reliably and securely. For this purpose, the frame elements have uprights constructed as hollow profiles with connecting arms fastened thereto. The connection of the frame elements can be accomplished by means of a connecting sleeve. In this case, a connecting sleeve serving as a coupling piece is inserted into an upright of the base frame and is fixed by means of a bolt having a locking cotter pin in such a way that a part of the connecting sleeve still projects from the upright in order to place a further upright on this part, which is likewise fixed by means of a locking bolt and a locking cotter pin. For a connecting sleeve, two bolts are therefore required, which pass through aligned openings in the connecting sleeve and the upright and are then each locked by means of a locking cotter pin.

Locking pins may also be used for fixing, in which case locking cotter pins need not be provided. The locking pin has an elongate pin element which passes through openings in the connecting sleeve and the upright, wherein a section which abuts against the circular outer circumference of the upright and which loops over the upright is provided, which section holds the locking pin in its position or clamps it on the outer circumference by its own weight. In the case of a single connection coupling, two locking pins are likewise required here.

Disclosure of Invention

The aim of the invention is to provide a plug-in connection for a frame element of a scaffolding or a scaffolding frame, which is simplified in terms of handling.

Claim 1 discloses a bolt clip according to the invention. The latching clip provides a novel attachment clip primarily for the above-described bracket components. The respective dependent claims disclose advantageous embodiments of the plug-in connection.

The core of the invention is a bolt clamp in the shape of a U-profile, the legs of which are at a distance from each other corresponding to the distance of two bores in the coupling piece. Furthermore, an inclined pin is articulated on one end of the bolt clamp.

Thus, as an alternative to up to four elements in the prior art, only a single element, i.e. the clip of the present invention, is required in order to connect two frame elements for the coupling. The bolt clip is inserted simultaneously into all bores, by means of which the coupling piece is to be fixed to the two frame elements which are to be connected to each other.

As a result, with improved ergonomics of the latch system, the speed of installation between the bracket members can be increased by the present invention. The latching clip is reliably self-locking and requires only few manipulations for installation. This enables a low-cost solution for the plug-in system. The length of the tilting pin is at least chosen such that it cannot tip over in the pipe and thus get stuck.

The plug-in connection of the support element according to the invention for connecting a scaffold can itself be formed by a connecting adapter according to claim 3. The connecting adapter has

A coupling member which can be inserted between the stent elements, an

-a bolt clip as described above.

Advantageously, the coupling piece of the connection adapter has a centrally encircling stop ring. Thereby, the insertion depth of the coupling on the first frame pipe can be defined. After the stop has been formed, the other half of the coupling element is left free for plugging in a second frame element.

The coupling is usually inserted into the hollow end of the pole. The present invention, however, also functions in the following configuration: the coupling piece is placed on the tube end of the frame on both ends on the outer periphery. Of course, the following trade-offs are equally valid: one end of the coupling is inserted into the tube end and placed on the tube end of the frame on the other end.

Detailed Description

Fig. 1 shows a bolt clamp 10 according to the invention made of a U-profile, which is articulated at one of its ends with an inclined pin 14. The tilting pin is hinged eccentrically in some way between the two end connecting strips of the leg of the U-profile, so that it has a tendency to tilt into a vertical position by its weight. Furthermore, as shown in the lower part of fig. 1, this makes it possible to form a stop flange by means of the tilting pin 14 in the event of this tilting pin rotating transversely to the leg of the clamp 10 to which it is hinged. This stop collar, which protrudes upwards in the drawing, forms a locking stop which prevents the component from being removed or accidentally falling out in the installed state of the bolt clamp 10.

The length of the tilting pin is at least chosen such that it cannot tip over in the pipe and thereby get stuck.

As shown, the tilting pin 14 also has a certain length with which it passes from one leg of the U-profile to the other leg in the locked state.

The length of this leg, to which the tilting pin 14 is hinged, is slightly greater than the length of the other leg, so that the tilting pin 14 can be lowered approximately at an angle of 90 degrees in the latched state. This curvature can be increased by the conically tapering end of the tilting pin 14, which can be stopped at a conical end of the free leg of the U-profile. Furthermore, the insertion process of the bolt clamp 10 into the above-mentioned bore hole is simplified by the tapering course of the legs of the U-profile and the ends of the tilting pin 14.

Fig. 2 shows the mounting of the plug-in connection to the frame element 20 of the scaffolding. Between the vertical bar ends of the vertical bars of the vertical bar of the frame element 20, a coupling element 16 with a centrally encircling locking ring is inserted (see detail a). The bolt clamp 10 is passed through a bore hole in the end of the respective frame piece, precisely in such a way that the tilting pin 14 is parallel to the leg of the U-profile holding the tilting pin. Fig. 3 shows an arrangement in the form of an inserted bolt clip 10.

The tilting pin 14 then automatically drops to the vertical position shown in fig. 4 based on its weight. The upper end of the angled pin 14 thus constitutes a stop flange for the jacket of the frame element 20, so that the bolt clamp 10 can no longer be removed from the borehole and thus from the connection location in this position shown.

Fig. 5 shows the interfitting between the bore of the coupling member 16 and the bore of the frame member 20. The outer diameter of the coupling member is of a small dimension so that it can be inserted into the open end of the frame member 20. Wherein all the bores lying in a line in the plugging direction of the plug pin are aligned with one another. The centering stop ring of the coupling 16 pushes the coupling a certain distance into the pipe of the frame element 20. The same is true for the frame member 20 that may be placed onto the coupling member 16.

Fig. 6 shows the interaction of the clip 10 with the coupling element 16. Which corresponds to the method steps as performed above in connection with fig. 2 to 4.
