Description

Box-type fining twisted steel stopping means

Technical field

The utility model belongs to technical field of bridge construction, more particularly, relates to a kind of box-type fining twisted steel stopping means.

Background technology

In the prestressed steel structure of civil engineering, rope membrane structure, curtain wall rope bar supporting construction, all there is drag-line need to apply prestressing force.Drag-line can be the various ways such as the parallel twisting of high-strength steel tow, the assembling of many steel strand or rod iron pull bar.At present, drag-line being applied to prestressed main method is both at home and abroad at the sandwiched force transmission beam in the shoulder place of stay cable end rope head, in the both sides of drag-line cable body, two or many hydraulic jack are arranged symmetrically on the force transmission beam of Suo Tou both sides, with feed-through hydraulic jack, synchronously rope head is applied to stretching force, and can rotate the branch sleeve that has positive and negative tooth in drag-line adjusting screw(rod) simultaneously, Jiang Suotou is fixed on anchoring otic placode and keeps required stretching force in cable body.For example: China Patent No. is 201120291886.1, open day is on May 23rd, 2012, discloses the patent document that a name is called tensioning equipment, and this utility model discloses a kind of tensioning equipment, and stretch-draw operating cost is low and easy to use.This tensioning equipment comprises stretch-draw jack, also comprises framework, and the top of described framework is provided with Chain block, and described Chain block is connected with described stretch-draw jack hook.For the ease of tensioning equipment is moved, improve the efficiency of stretch-draw operation, can walking mechanism be set in base of frame, such as wheel.

But, adopt above-mentioned stretching construction device to have the following disadvantages, before stretch-draw operation, need to set up scaffold, after the stretch-draw end of job, need to remove scaffold, to waste time and energy, the cycle of stretch-draw operation is longer, and efficiency is low.

Summary of the invention

the problem that 1, will solve

For the above-mentioned problems in the prior art, the utility model provides a kind of box-type fining twisted steel stopping means, its muscle device of wearing by cuboid carries out spacing to fining twisted steel, guaranteed better limit strength, and while using without erection bracket, simple in structure, be easy to make, be conducive to promote.

2, technical scheme

In order to address the above problem, the technical scheme that the utility model adopts is as follows:

A fining twisted steel stopping means, comprises base, also comprise fixed head, wear muscle device, described in wear the upper surface that muscle device is fixed on base; Described fixed head is vertically fixed on the end of base lower surface; The described body of wearing muscle device is cuboid, and its inside has manhole vertically; Described length of wearing muscle device is 15-20cm.

The length of wearing muscle device further, is 18cm.

Further, described in, wear muscle device and have 13-24.

3, beneficial effect

Than prior art, the beneficial effects of the utility model are:

(1) of the present utility modelly comprise base, fixed head, wear muscle device, wear the upper surface that muscle device is fixed on base; Fixed head is vertically fixed on the end of base lower surface; The body of wearing muscle device is cuboid, and its inside has manhole vertically; During use, can guarantee better limit strength;

(2) length of wearing muscle device of the present utility model is 15-20cm, makes limit effect remarkable, avoids the skew of fining twisted steel.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that the utility model is worn muscle device;

In figure: 1, base; 2, fixed head; 3, wear muscle device.

The specific embodiment

Below in conjunction with specific embodiment, the utility model is further described.

embodiment 1

As shown in Figure 1 and Figure 2, a kind of box-type fining twisted steel stopping means, comprises base 1, also comprises fixed head 2, wears muscle device 3, wears the upper surface that muscle device 3 is fixed on base 1; Fixed head 2 is vertically fixed on the end of base 1 lower surface; The body of wearing muscle device 3 is cuboid, and its inside has manhole vertically; The length of wearing muscle device 3 is 15cm; The length of wearing muscle device 3 is 18cm; Wear muscle device 3 and have 15.During use, directly the fixed head of this tensioning equipment 2 is welded on the body of stretch-draw girder steel, and make to wear manhole on muscle device 3 and aim at and wear muscle groove on girder steel body, rear layout fining twisted steel, make it, through manhole and the steel strand anchoring of wearing muscle groove and the girder steel other end, to carry out stretching construction.

embodiment 2

with embodiment 1, difference is, the length of wearing muscle device 3 is 18cm, and wearing muscle device 3 has 13.

embodiment 3

with embodiment 1, difference is, the length of wearing muscle device 3 is 20cm, and wearing muscle device 3 has 24.
