Description

(; 0 1

The invention relates to the field of Construction, in which iiacTb load-bearing elements are made of ropes: mast supports on straps, Wing bridges, cable-stayed covers, etc.

The purpose of the invention is to increase reliability by allowing loads to be applied to the traverses while simultaneously removing the loads from the threaded tensioning elements.

FIG. Figure 1 shows a tension coupling with a tensioner, the general view of FIG. 2 shows section A-A in FIG. one; on 1FIG. 3 shows a section BB in FIG. one. ; The tension coupling with tensioning device consists of end tracts - 1brow 1, wrench, aerial washers 2. To trap- versts 1 by means of pins 3 are attached Rope sleeves. 4 with the ropes fixed therein 5. The cross braces 1 are interconnected by two pairs of plate threads 6 with holes 7 for the fingers 8. The wires 6 are prevented from moving arbitrarily relative to the cross arms 1 in the process of moving the fingers 8 by the stops 9

Dp speed adjustment the distance between the sleeves 4 applied multi-faceted eccentrics 10, which are installed on the fingers 8 above one of the end cross member f (top), and | adjusting strip gaskets 11

In order to install the clamping bolts 12, holes 15 are inserted into the holes 13 of the cantilever sections 14 | yoke 1. I In order to reduce the length of the clamping I bolts 12, the device includes an intermediate yoke 16, also attached to the weight of 6 with the fingers 8.

The coil dynamometers 17 of a known construction are mounted on the clamping bolts 12.

An emphasis on the dynamometers 17 is transmitted by the tension nuts.

The rigid coupling works as follows.

For example, using an assembly winch (not shown), the traverse 1, with the ropes 5 attached to it, is pulled together and connected with the help of the fingers 8 to the paired plate plungers of the straps 6, inserted the fingers 8 into the outer holes 7. Further be installed intermediate traverse 16.

After installing the clamping bolts 12 and dynamometers 17, the tensioning nuts begin to rotate. At the same time, on the movable yoke 1 (top in Fig. 1, the yoke), the finger 8 is released from the load, which is then removed from the hole to further move the yoke 1.

When the end of the crosspiece 1 is moved to a sufficient distance, the multifaceted eccentric 10 is installed.

Subsequently, as the tension nut is rotated as the distance between the crosspiece 1 and the face of the eccentric 10 increases, the latter turns around the finger to the next edge that fills the distance.

If necessary, a more fine adjustment than the eccentric 10 allows to do, a strip strip 11 can be installed between it and traverse 1.

The tension is read on the scale of the dynamometer indicator 17. After the traverse 1 is brought up to the calculated skew (shown by dashed lines), the rollers 15, the clamping bolts 12 and the dynamometer 17 are removed, rearranged to the other side (shown by dotted lines) and the process is repeated until the calculated tension is obtained. married in a rope.

When the tensioning process is completed, the intermediate yoke 16, rollers 15, tension bolts 12 and dynamometer 17 are removed for storage until the next adjustment of the tension.

Instead of tensioning bolts 12, tension can be carried out with a jack.
