Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction safety fixing bolt. Background Technology

[0002] In the field of building construction, safety bolts are key components that connect building structures with safety protection facilities (scaffolding, safety nets, ladders, etc.). Their reliability is directly related to the life safety of construction workers and the quality of the project.

[0003] Traditional fasteners mostly achieve fixation through the combination of bolts and screws, and usually a washer of fixed thickness is placed between the screw and the part to be fixed. Such structures have the disadvantages of limited clamping force adjustment, insufficient adaptability to different scenarios, and limited functional expansion. To address these issues, we propose a new type of safety fastener for building construction. Utility Model Content

[0004] The purpose of this utility model is to provide a safety fixing bolt for building construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a building construction safety fixing bolt, comprising clamps at the upper and lower ends, screws on both sides of the clamps, and nuts welded to the top of each screw;

[0006] Both sides of the clamp have through-holes, and an L-shaped connecting rod is provided in the recess. A slider is fixedly connected between the lower ends of the connecting rod. A limit block is fixedly connected to the outer wall of the slider. A lead screw is threaded through the slider and extends to the outer end of the clamp. A U-shaped washer with a stepped cross-section is fixedly connected to one end of the connecting rod.

[0007] Preferably, the two inner sidewalls of the notch are provided with grooves that match the diameter of the limiting block.

[0008] Preferably, a handle is fixedly connected to one end of each lead screw.

[0009] Preferably, the inner diameter of the U-shaped gasket matches the outer diameter of the screw.

[0010] Preferably, the diameter of the stepped surfaces of the U-shaped gasket is larger than the diameter of the nut.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by rotating the handle to drive the lead screw to rotate, the slider slides along the groove, thereby pushing the L-shaped connecting rod to adjust the position of the stepped surface of the U-shaped gasket, realizing the dynamic change of the gasket thickness, so that the fixing bolt can adapt to high-strength fixing scenarios or light-weight fixing scenarios.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 The present invention provides the following technical solution:

[0018] Example 1: A building construction safety fixing bolt includes a clamp 1 at the upper and lower ends, a screw 11 on both sides of the clamp 1, and a nut 12 welded to the top of each screw 11.

[0019] In use, the staff will clamp the two clamps 1 onto the steel pipes at the upper and lower ends respectively, and then use a tool to rotate the screw 11 through the nut 12. By rotating the nut at the bottom of the screw 11, the two steel pipes can be clamped and fixed by the two clamps 1.

[0020] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a notch 101 is provided through both sides of the clamp 1, and an L-shaped connecting rod 21 is provided in the notch 101. A slider 22 is fixedly connected between the lower ends of the connecting rod 21. A limit block 23 is fixedly connected to the outer wall of the slider 22. A screw rod 24 is threadedly connected to the slider 22, which rotates through and extends to the outer end of the clamp 1. A U-shaped washer 2 with a stepped cross-section is fixedly connected to one end of the connecting rod 21. A groove 102 matching the diameter of the limit block 23 is provided on both inner side walls of the notch 101. A handle 25 is fixedly connected to one end of the screw rod 24. The diameter of the multiple stepped surfaces of the U-shaped washer 2 is larger than the diameter of the nut 12.

[0021] In use, first rotate the handle 25 to drive the lead screw 24 to rotate. At this time, the lead screw 24 will drive the slider 22 to move. The slider 22 will slide along the slide groove 102 through the limit block 23. Then the slider 22 will drive the connecting rods 21 set at both ends to move, so that its U-shaped washer 2 moves along the wall of the screw 11. The stepped surface of the U-shaped washer 2 corresponds to the nut 12, thereby changing the thickness of the U-shaped washer 2 to adapt to different installation requirements.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
