The patent adopts a support tie beam, which is fixed to the side of the lattice column; the clamp bracket is located on the outside of the tie beam channel steel, and the clamp bracket includes a positioning seat, which is buckled in the groove of the tie beam channel steel and adapted thereto; a second oblong hole is vertically opened at the upper end of the vertical beam; the cross beam is located at the upper end of the vertical beam, and the end of the cross beam is fixedly connected to the upper end of the vertical beam by short bolts; the vertical beam and the positioning seat are connected together by long bolts; The beneficial effect is as follows: a first oblong hole is horizontally opened at the end of the angle steel, a third oblong hole is horizontally opened at the end of the cross beam, and a second oblong hole is vertically opened at the upper end of the vertical beam. The angle steel and the cross beam are connected to the vertical beam by bolts. Therefore, the size of the clamp bracket of the device can be adjusted according to on-site requirements to adapt to steel supports of different sizes, thereby solving the problem that the steel support clamps used in existing subway stations are mostly assembled by welding, so that the clamps after welding can only position steel supports of specified specifications, resulting in the problem that the scope of application of the clamps is limited.

[0004] In the process of using clamps to position steel supports, there is a problem that, for example, the clamps are mostly assembled with a combination of bolts and nuts. During the installation process, since the nuts are on the inner side of the clamp frame, it is difficult for workers to limit the position of the nuts when tightening the bolts. As a result, when the workers perform assembly operations, the nuts are easy to rotate with the bolts, making it difficult to tighten the bolts, resulting in a weakened fixing effect of the clamp.

[0007] Furthermore, a nut sleeve is fixedly connected to the side surface of the force-carrying plate, and a hexagonal groove is formed on the side surface of the nut sleeve.

[0008] Furthermore, the number of the connecting sliders is two, and the two connecting sliders are arranged symmetrically with respect to the connecting plate.

[0009] Furthermore, the number of the connecting plates is two, and the two connecting plates are symmetrically arranged with respect to the cross frame, and the connecting plates are in contact with the surface of the cross frame.

[0010] Furthermore, the auxiliary unit includes a support block, which is fixedly connected to the inner wall of the cross frame, and a socket is provided on the side surface of the support block. A guide rod is bolted to the inner wall of the support block located on the socket, and a damping sleeve is sleeved on the surface of the guide rod, and a limit block is fixedly connected to the surface of the damping sleeve.

[0011] Furthermore, there are two support blocks, which are horizontally equidistantly arranged relative to the cross frame; there are two guide rods, which are symmetrically arranged relative to the support blocks; the limit block is fixedly connected to the surface of the connecting slider, and the limit block contacts the inner wall of the cross frame.

The force-loading plate is subjected to force to push the nut sleeve and the nut. When the force-loading plate moves to the maximum spacing, the force-loading plate is fixed to the connecting plate with the help of screws, and the restriction on the nut is then completed; and then when tightening the clamp, the connecting plate is moved, and the connecting plate is subjected to force to drive the force-loading plate and the connecting slider, and the force-loading plate is subjected to force to drive the nut sleeve and the nut to move, and the connecting slider is subjected to force to drive the limit block, and the limit block is subjected to force The damping sleeve is driven, and the damping sleeve is subjected to force and moves under the guidance of the guide rod. When the nut moves to a position matching the bolt, the connecting plate is stopped from being pushed, and at the same time, the limit block and the damping sleeve lose their force and stop moving. Then, with the cooperation of the damping sleeve, the guide rod and the limit block, the position of the constraint unit and the nut installed inside it can be restricted, and then the bolt tightening operation can be carried out. By setting the constraint unit and the auxiliary unit, the position of the nut of the clamp can be limited, thereby reducing the problem that the staff finds it difficult to restrict the position of the nut when installing the clamp, which makes the nut easy to rotate with the bolt, and further improves the firmness and installation efficiency of the clamp.

[0022] Specifically, a nut sleeve 44 is fixedly connected to the side surface of the load-bearing plate 43, and a hexagonal groove 45 is formed on the side surface of the nut sleeve 44. The nut sleeve 44 is provided to restrict the nut in the clamp assembly 3 to increase the stability of the nut during assembly.

[0023] Specifically, there are two connecting sliders 41 , and the two connecting sliders 41 are disposed symmetrically with respect to the connecting plate 42 .

[0024] In this embodiment, a connecting slider 41 is provided, through which the position of the connecting plate 42 can be constrained and the moving direction of the connecting plate 42 can be guided.

[0025] Specifically, there are two connecting plates 42, which are symmetrically arranged about the cross frame 33, and the connecting plates 42 are in contact with the surface of the cross frame 33. The connecting plates 42 are arranged to support and fix the position of the load-bearing plates 43, thereby achieving the assembly effect of the load-bearing plates 43.

[0026] In this embodiment, the auxiliary unit 5 includes a support block 51, which is fixedly connected to the inner wall of the cross frame 33. A socket 52 is provided on the side surface of the support block 51. A guide rod 53 is bolted to the inner wall of the socket 52 of the support block 51.

There are two guide rods 53, which are symmetrically arranged with respect to the support blocks 51.

[0029] Working principle: When installing the clamp, install the nut used for fixing into the hexagonal groove 45 on the nut sleeve 44. After placing the nut, hold the load-bearing plate 43 and align it with the gap between the connecting plates 42 on both sides, push the load-bearing plate 43, and the load-bearing plate 43 pushes the nut sleeve 44 and the nut under force.

When the nut moves to a position that matches the bolt, it stops pushing the connecting plate 42. At the same time, the limit block 55 and the damping sleeve 54 lose their force and stop moving. Then, with the cooperation of the damping sleeve 54, the guide rod 53 and the limit block 55, the position of the constraint unit 4 and the nut installed therein can be restricted, and then the bolt tightening operation can be performed. By setting the constraint unit 4 and the auxiliary unit 5, the position of the nut of the clamp can be limited, thereby reducing the problem that it is difficult for the staff to limit the position of the nut when installing the clamp, resulting in the nut easily rotating with the bolt, and further improving the firmness and installation efficiency of the clamp.
