AI Technical Summary
Before the prestressed steel strand tensioning, the traditional clamp insertion and tamping method is inefficient. Workers need to frequently insert the steel strand end, which increases physical consumption and time, and it is difficult to replace the chuck individually.
A structure including a lower substrate, a fixing rod, an upper substrate, a torsion spring, a semicircular chuck and a threaded rod is designed. The clamp is slid along the steel strand to the bottom through a hand-held structure, and then the lower substrate and the fixing rod are closed, so that the chuck and the clamp are abutted, so that the clamp is tamped quickly.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a structure for fast positioning of clips. Background Art
[0002] Before prestressed steel strands are tensioned, the clips between the steel strands and the anchor plates need to be compacted. The traditional method is for workers to insert a steel pipe into the steel strands and insert and compact the clips. Because the steel strands need to reserve about 80 cm in length for installing the jack when tensioning, the steel pipe must be inserted from the end of the steel strand when each clip is inserted and compacted, and then the steel pipe is pulled out after the insertion and compaction is completed. The reciprocating stroke is about 80*2=160 cm, which increases the workload of the personnel, takes a long time, and is inconvenient to replace the end. When inserting the clips, the personnel need to exert force to compact them forward, and during the compaction process, the end will collide with the anchor plate. When the end is deformed due to the collision, it can only be replaced as a whole, which is less practical.
[0003] In order to solve the above problems, we have proposed a structure for rapid positioning of the clip. Utility Model Content
[0004] The utility model aims to provide a structure for fast positioning of a clip, which solves the problem that the existing positioning structure has low efficiency when inserting and tamping the clip and cannot replace the end separately.
[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a structure for rapid positioning of a clip, comprising a lower base plate, a fixing rod is fixedly sleeved inside the lower base plate, the surface of the fixing rod is rotatably connected to an upper base plate, a torsion spring is sleeved on the surface of the fixing rod, the two ends of the torsion spring are respectively welded to the inside of the lower base plate and the upper base plate, a first semicircular chuck and a second semicircular chuck are respectively arranged inside the lower base plate and the fixing rod, threaded rods are symmetrically welded on the back-to-back sides of the first semicircular chuck and the second semicircular chuck, through grooves are symmetrically opened inside the lower base plate and the upper base plate, and a fixing nut is threadedly connected to the surface of the threaded rod.
[0006] The above technical solution can improve the efficiency of inserting the clamp. There is no need to insert the clamp from the end of the steel strand every time. Only a tamping stroke of 10*2=20cm is required, which reduces the physical exertion of workers. At the same time, it is easy to replace the clamp, which is simple and convenient to operate and reduces the maintenance cost of personnel.
[0007] The utility model is further configured as follows: an anti-collision pad is installed on one side of the first semicircular chuck and the second semicircular chuck.
[0008] By adopting the above technical solution and setting the anti-collision pad, the front ends of the first semicircular chuck and the second semicircular chuck can be protected, reducing the wear of the front ends of the first semicircular chuck and the second semicircular chuck when they collide.
[0009] The utility model is further configured as follows: anti-slip pads are installed on the back-facing sides of the lower base plate and the upper base plate.
[0010] By adopting the above technical solution and providing the anti-skid pad, the friction between the surfaces of the lower substrate and the upper substrate can be increased, thereby increasing the friction between the surfaces and the hands of the user.
[0011] The utility model is further configured as follows: a hanging ring is welded on one side of the lower base plate.
[0012] By adopting the above technical solution and providing the hanging ring, it is convenient for personnel to hang and place the positioning structure.
[0013] The utility model is further configured as follows: the threaded rod and the fixing nut are both made of stainless steel.
[0014] By adopting the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.
[0015] The utility model is further configured as follows: the torsion spring is made of carbon spring steel.
[0016] By adopting the above technical solution, the torsion spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.
[0017] In summary, the utility model has the following beneficial effects:
[0018] 1. The utility model first slides the clip inwards to the bottom along the steel strand, and after the clip is placed, the hand-held structure makes the first semicircular clamp and the second semicircular clamp be located at the rear end of the clip, and then the hand is clenched to close the lower base plate and the fixing rod. After the lower base plate and the fixing rod are closed, the first semicircular clamp and the second semicircular clamp will move against the rear end of the clip, and then the hand-held structure can drive the clip to tamp inwards, which can improve the insertion efficiency of the clip, and there is no need to insert it from the end of the steel strand every time. Only a tamping stroke of 10*2=20cm is required, which reduces the physical exertion of workers.
[0019] 2. According to the utility model, when the first semicircular chuck and the second semicircular chuck are damaged, the fixing nut is first loosened with a tool. After the fixing nut is loosened and removed, the restriction on the threaded rod is released. Then, the chuck is grasped by hand to drive the threaded rod to be removed, and finally a new chuck is put in and retightened. The chuck can be easily replaced, the operation is simple and convenient, and the maintenance cost of personnel is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
