Vynález sa týká lešeňove) spojky, ktorá umožňuje spoj dvoch lešeňových trubiek v lubovolnom uhle. Spojka umožňuje spoj i v polohe 0’, čo je výhodné pri zdvojovaní, respektive spriahnutí dvoch lešeňových trubiek. Tento spoj umožňuje i jednoduché použitie i pri iných konštrukciách, ako například pri stíplkoch debnenia apod., a jednoduché, staticky výhodné vytváranie lešeňových konštrukcií. Spojka je dvojdielná. Diel sa skládá z opernej došky, přítlačného šroubu, s kíorýml opiera na trubku, a přítlačných šroubov. Medzi dvojicu trubiek sa može vložit vložka, ktorá předurčuje uhol spoja. Spojku je možno využit pri zvláštnych i běžných lešeňových konštrukciách, na atypické spoje.The invention relates to a scaffolding coupler that enables the connection of two scaffolding tubes at any angle.

Description

BACKGROUND OF THE INVENTION The present invention relates to a scaffolding clutch which allows the joining of two scaffold tubes at Tubovolny angle.

The coupling allows the connection to be made even in the 0 'position, which is advantageous for doubling or coupling the two scaffold tubes. This connection also makes it easy to use in other constructions such as formwork piles and the like, and simple, statically advantageous scaffold construction.

The clutch is two-piece. The part consists of a support dock, a pressure screw, a pipe support and a pressure screw. An insert that predetermines the joint angle can be inserted between the pair of tubes.

The coupling can be used for special and common scaffold constructions, for atypical joints.

The invention addresses the scaffold tube coupling. In the prior art, rectangular couplings, dedicated, whose disadvantage is that they have a small amount of utilization, variability, especially in the case of uneven double pipe joints where additional pipe has to be used, with reduced static load-bearing capacity, are known. There are also known coupling couplings which have allowed a non-rectangular connection, but this has not been provided at the desired angle, which has reduced the static load capacity, the rigidity of the scaffold structure. Also known are sloping couplings that have been dedicated, only for one angle given by its construction. In the case of said couplings, the aforementioned property does not shake up in combination and in addition with the possibility of simple and variable mounting, the possibility of selecting the angle, the choice of joint or rigid joint, or the accuracy of the angle of the coupled pair of tubes.

These drawbacks are eliminated by a clutch consisting of thrust bolts with abutments, two abutment plates abutting each other and coupled by a pair of clamping bolts with nuts and washers on their edges, according to the invention wherein the abutment bolts are provided with thrust bolts and a notch is formed on their edge, into which the end of the tightening screw provided with the nut is inserted, the notch provided edge being bent towards the nut.

The novel effect of the clutch of the invention is to combine a number of effects, such as a bent joint of a pair of pipes, the possibility of stepless selection of the necessary angles directly on the building, the choice of a non-joint joint by inserting the liner between a pair of bonded tubes, thereby increasing the rigidity of the structure, using a liner that determines the desired angle, simple selection of the exact angle. Also a new effect is the possibility of a parallel connection of a pair of tubes, thereby coupling the bending of the stressed tubes, or doubling the vertical bars. This coupling or doubling is also advantageous in that the number of couplings per pipe length can be determined on the basis of the static calculation, since the couplings can be mounted in succession. The clutch liner creates a statically advantageous friction surface, eliminates the need for wear. damage to the tubes, creating a gap through which the 60 ° to 120 ° clutch can be fitted or hooked. A higher effect is also the simple mounting and assembly of the clutch.

In the accompanying drawings, there is shown a clutch according to the invention, in which Fig. 1 shows a connector mounted on parallel tubes without an insert in a cross section through the tubes, Fig. 2 shows a connector placed on rectangular tubes in a side view. FIG. 3 indicates a 0 ° insert, but as one of the alternative insert angles.

The pipe coupling 7 is two-piece, one of which consists of an abutment support 1. It has a screw hole on one side with a nut 3 which is permanently retained on the coupling, on the other hand it has a longitudinal slot 11 into which the screw 2 pushing. The overhang of the edges 10 of the notch 11 of the claw 1 prevents the screw from falling out, thereby disintegrating the clutch. In addition, the clutch support plate 1 has a centrally supported support 5 which is pivotally attached by a pressure screw 6, on which a nut is locked by a spot weld. The support 5 serves to spread the pressure, increase the skid resistance, and prevent the scaffold tube 7 from deforming. The coupling can be used without insert or with insert. The insert consists of two longitudinally spaced portions 8 of tubes, welded together by welding 9, which predetermines the insertion angle. FIG. 2 indicates the use of a 90 ° rectangular joint. The angle of the insert can be marked in the insert body to avoid confusion of the inserts.

The flexible coupling can be used for mounting sloping and parallel tubular scaffold constructions, concrete sloping constructions when switching to a rectangular structure, for creating pillars in formwork of ceilings, for coupling or doubling of parallel scaffold tubes, thereby increasing the static load capacity of the pipes or their spread. By allowing the slanted pipe to be directly fed, for example, scaffolding on a pillar, the use of a crossbar for conventional scaffolding is sometimes eliminated. It allows quick and easy assembly on site with high design variability.
