The invention relates to a universally applicable. Screw terminal for the transport and installation of rails, profile beams or profiled composite sheet metal panels u. dglv

Characteristics of the known technical solutions For TUL processes and assembly of rails, profiled beams or also profiled composite sheet metal panels and similar parts, various forms of grippers are known as pliers, claws and clamps, which have different disadvantages according to their operating conditions.

For example, grapples, in the operating principle of shear clamps, have been described in DD - AP 3078; DD - AP 9939; DE-AS 1229692; DE - AS 1242339 and DE - PS 844960 were known, the great disadvantage that. these devices over the hinged parts, even one

Object of the invention.

The object of the _invention} a universal screw terminal for TUL - to create processes and installation of rails, profiled beams, profiled composite metal sheets, etc., which has a high utility value and is easy to mass production, efficiently and cost-effectively. ²

Explanation of the essence of the invention

It is an object of the invention to develop a universally applicable screw terminal, which has a low overall heightj on all rails, profile beams, profiled composite sheet metal panels u. Like., Can be safely clamped, has a positive locking and by simple construction less susceptible to interference and easy to handle 'is.

This is essentially achieved according to the invention in that two jaws are moved by means of a threaded bolt against each other, with a jaw fixed to the threaded bolt and the second jaw is fixedly connected to a arranged on the threaded bolt slide bushing. ^; The sleeve of the attachment part is rotatably mounted on the sliding bush. Between a clamping nut and the outside of the clamping jaw attached to the sliding bush, there is a spring element, preferably designed as a plate spring packet, which has a spacer whose mobility assumes a predetermined value when the predetermined clamping force is reached; 'Instead of the spring elements and the spacer body and a torque nut can be arranged, which via the torque sleeve, preferably with external hex, the friction lining, the spring elements and the pressure ring on the parent core a defi

The erfindungsgeinäße screw according to Pig. 1 consists of two jaws 1j2 with Pormschlußspitzen 10, which are moved by means of a threaded bolt 3 against each other. The jaw 1 is fixedly connected to the threaded bolt 3 and the jaw 2 fixed to a slide bush 4 slidably mounted on the threaded bolt 3.

Crane rails shown, the jaws 1, 2 are adapted to the rail head. In place of the spring element 8 and the spacer body 9, a torque nut 11 is arranged. About the torque sleeve 11.2, preferably with external hex, the friction lining 11.4, the spring elements 11.'5 »preferably disc springs, and the pressure ring 11.3 is a defined torque on the Mother core 11 "1 transmitted, which generates a corresponding clamping force.

In Fig. ₀ ^; 3, 4 it is shown that the load receiving side of the jaws 1j2 are designed for centric loading and for increasing the clamping force as an inclined plane "12." In addition, the jaws 1, 2 are held longer and are thus resilient truss beams.

According to Fig. 4, 5, the jaws 1, 2 are also formed as a resilient truss beams, at the ends, for example, conical bolts 13 are attached «.

The screw according to the invention has the advantage that it has a very low height, can be produced efficiently and inexpensively in mass production and that it is easy to handle and low maintenance due to its simple structural design. The screw terminal according to the invention also has the advantage that it can be replaced by the quickly interchangeable, differently profiled clamping jaws for all rails, profile beams, profiled composite sheet panels u, the like. can be used as load handling equipment. ' Another advantage is that by the arrangement of the disc spring package bzw.V the torque nut a predetermined clamping force to stop the load is possible and the clamping action against the load can be increased by forming the jaws as a crossbeam. ^: It is also an advantage that by the arrangement of a pivotable sleeve on the stop member, the screw is used in cable hangers, without causing large torques are transmitted to the jaws. Another advantage is that a self-locking locking of the screw is achieved with firmly tightened spindle on the plate springs or ^: torque nut.
