Novel high-strength bolt for building structure

Abstract

This utility model relates to the field of bolt technology and discloses a novel high-strength bolt for building structures, including a bolt rod. A first lead screw is rotatably connected to the inner wall of the left end of the bolt rod, and a nut is threadedly connected to the outer wall of the first lead screw. The nut is connected to the bolt rod via a locking assembly. A second lead screw is rotatably connected to the inner wall of the right end of the bolt rod, and a rotating shaft is rotatably connected to the left end of the second lead screw. A limit assembly is provided at the left end of the rotating shaft. In this utility model, by moving the nut out of the outer wall of the bolt rod, the nut cannot drive the bolt rod to rotate. This design, which prevents accidental disassembly of the bolt rod, effectively avoids loosening of the structural connection due to worker error or unauthorized disassembly. Furthermore, the limit block can limit the nut on the bolt rod, preventing the nut from detaching from the bolt rod, thus enhancing the reliability and safety of the entire building structure.

Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a new type of high-strength bolt for building structures. Background Technology

[0002] In the field of modern architecture, as buildings become increasingly taller, their spans larger, and their functions more complex, the requirements for connecting components in building structures are also getting higher and higher. High-strength bolts, as key connecting components, have a profound background in their development and evolution.

[0003] In traditional building connection structures, due to the lack of an effective mechanism to prevent bolt components from loosening or being disassembled accidentally, bolt connections are prone to failure due to human factors during complex construction and long-term use. For example, in the construction of high-rise buildings, multiple trades work together frequently, and workers may accidentally rotate the bolts or tighten the nuts due to accidental collisions or misoperations, causing the installed bolt connections to loosen, which in turn affects the integrity and stability of the building frame structure.

[0004] In response to the technical problem of workers accidentally loosening installed bolts, this application proposes a new type of high-strength bolt for building structures. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new type of high-strength bolt for building structures. Through this design that prevents the bolt from being accidentally disassembled, it effectively avoids loosening of structural connections caused by worker misoperation or unauthorized disassembly. Furthermore, the limiting block can limit the nut on the bolt, preventing the nut from detaching from the bolt, thereby enhancing the reliability and safety of the entire building structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel high-strength bolt for building structures, comprising a screw rod, a first lead screw rotatably connected to the inner wall of the left end of the screw rod, a nut threadedly connected to the outer wall of the first lead screw, the nut being connected to the screw rod via a locking assembly, a second lead screw rotatably connected to the inner wall of the right end of the screw rod, a rotating shaft rotatably connected to the left end of the second lead screw, and a limit assembly provided at the left end of the rotating shaft.

[0007] Furthermore, the engaging assembly includes fixing blocks fixedly connected to the four sides of the outer wall of the screw, and the inner wall of the nut has fixing grooves corresponding to the number of fixing blocks, and the outer wall of the fixing blocks fits the shape of the inner wall of the fixing grooves.

[0008] Furthermore, a first knob is fixedly connected to the left end of the first lead screw to drive the first lead screw to rotate.

[0009] Furthermore, the limiting assembly includes two connecting rods rotatably connected to the inner wall of the left end of the rotating shaft, and each connecting rod has a limiting block rotatably connected to its left end. The outer wall of the limiting block is slidably connected to the inner wall of the screw.

[0010] Furthermore, a second knob is fixedly connected to the right end of the second lead screw to drive the second lead screw to rotate.

[0011] Furthermore, a baffle is fixedly connected to the left end of the outer wall of the screw.

[0012] Furthermore, the nut has a hexagonal structure, which, when used with a wrench, facilitates the rotation of the screw. Furthermore, the entire screw structure is made of high-strength alloy steel.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when the screw is installed, the first screw is rotated by turning the first knob, which moves the nut out of the outer wall of the screw, making it impossible to rotate the screw through the nut. This design to prevent the screw from being accidentally disassembled effectively avoids the loosening of the structural connection caused by worker misoperation or unauthorized disassembly.

[0014] 2. In this utility model, rotating the second knob moves the second lead screw into the screw rod, thereby moving the rotating shaft into the lead screw rod. The rotating shaft then moves the limiting blocks on both sides out of the lead screw rod through the connecting rod, thereby limiting the nut on the screw rod and preventing the nut from detaching from the screw rod, thus enhancing the reliability and safety of the entire building structure.

[0017] 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.

[0018] Refer to Figure 1 and Figure 2 This utility model provides an embodiment of a novel high-strength bolt for building structures, comprising a screw 1, a first lead screw 4 rotatably connected to the inner wall of the left end of the screw 1, a nut 5 threadedly connected to the outer wall of the first lead screw 4, and fixing blocks 7 fixedly connected to all four sides of the outer wall of the screw 1. The inner wall of the nut 5 has fixing grooves 6 corresponding to the number of fixing blocks 7, and the outer wall of the fixing blocks 7 matches the inner wall of the fixing grooves 6. A first knob 3 is fixedly connected to the left end of the first lead screw 4 to drive the first lead screw 4 to rotate. A baffle 2 is fixedly connected to the left end of the outer wall of the screw 1. The nut 5 has a hexagonal structure and, when used with tools such as a wrench, facilitates the rotation of the screw 1. The entire structure of the screw 1 is made of high-strength alloy steel.

[0019] Specifically, when it is necessary to move the nut 5 to the outer wall of the screw 1, a wrench is used to hold the nut 5 in place so that it does not rotate with the first lead screw 4. Then, the first knob 3 is turned, which drives the first lead screw 4 to rotate. The first lead screw 4 then moves the nut 5 to the right, so that the fixing groove 6 on the nut 5 engages with the fixing block 7 on the screw 1. When the positions of the fixing groove 6 and the fixing block 7 do not correspond, the wrench can be turned to adjust the position of the nut 5 so that they correspond. The entire structure of this device is made of high-strength alloy steel to ensure the connection reliability of the building structure under complex loads.

[0020] Referring to Figure 3, a second lead screw 9 is rotatably connected to the inner wall of the right end of the screw 1. A rotating shaft 10 is rotatably connected to the left end of the second lead screw 9. Two connecting rods 11 are rotatably connected to the inner wall of the left end of the rotating shaft 10. Each connecting rod 11 is rotatably connected to a limit block 12 at its left end. The outer wall of the limit block 12 is slidably connected to the inner wall of the screw 1. A second knob 8 is fixedly connected to the right end of the second lead screw 9 to drive the second lead screw 9 to rotate.

[0021] Specifically, when the second knob 8 is turned, the second lead screw 9 will rotate. The second lead screw 9 is threadedly connected to the inner wall of the right end of the screw 1, which will cause the second lead screw 9 to move to the left. The rotating shaft 10 is in a rotating relationship with the second lead screw 9, which will move the rotating shaft 10 to the left, so that it pushes the limiting block 12 out of the screw 1 through the connecting rod 11.

[0022] Working principle: In use, insert screw 1 between two building structures to connect them. Then, install the nut on screw 1. Use one wrench to hold the nut 5 and another handle to hold the nut. At this time, the fixing groove 6 on the inner wall of the nut 5 engages with the fixing block 7 on the outer wall of the screw 1, allowing the nut 5 to drive the screw 1 to rotate, thus installing the nut. The baffle 2 and the nut fix the two building structures together. Then, turn the first knob 3, causing the first lead screw 4 to rotate. The first lead screw 4 moves the nut 5 to the left, causing the nut 5 to disengage from the outer wall of the screw 1, thus preventing the nut 5 from driving the screw 1 to rotate. This effectively avoids loosening of the structural connection due to worker misoperation or unauthorized disassembly. Subsequently, turn the second knob 8, causing the second lead screw 9 to rotate, thus moving the second lead screw 9 inwards towards the screw 1, which in turn moves the rotating shaft 10 to the left side of the screw 1. The connecting rod 11 is then pressed to both sides, thereby pushing the limiting block 12 out of the screw 1, thus limiting the nut and effectively preventing the nut from coming off.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
