Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to an auxiliary connector for steel structures. Background Technology

[0002] Steel structures, a type of building structure primarily made of steel, are widely used in modern architecture. During steel structure construction, especially for large structures such as space frame steel structures, it is typically necessary to embed fixed columns in the ground and then hoist the top beams with spans to the connection points on either side of the columns. In this process, workers need to connect the top beams to the columns using bolts and fasteners, a step that often requires auxiliary connectors. However, traditional auxiliary connectors are cumbersome to assemble and disassemble, inefficient, and have low compatibility and reusability with different types of steel components. This not only increases construction difficulty and cost but also affects the overall construction progress and quality. Therefore, it is necessary to provide a steel structure auxiliary connector with high assembly and disassembly efficiency and high reusability for various types of steel components to solve the problems existing in the current technology. Utility Model Content

[0003] The present invention aims to overcome the defects of the prior art and provide an auxiliary connector for steel structures, thereby addressing the cumbersome and inefficient nature of existing steel structure connection processes.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0005] A steel structure auxiliary connector, characterized in that it includes a base and a plug-in column. A turntable is provided on the outer side of the base, and a forward / reverse threaded rod is provided on the inner side of the base. One end of the turntable is connected to one end of the forward / reverse threaded rod. Threaded sleeves are threadedly connected to both sides of the surface of the forward / reverse threaded rod. A connecting column is fixedly connected to the top of each threaded sleeve, and a sleeve column is fixedly connected to one end of each connecting column. A bearing plate is provided on the top of the plug-in column, and the plug-in column is located inside the sleeve column. By rotating the turntable, the forward / reverse threaded rod rotates, thereby causing the two threaded sleeves to move inward or outward. The threaded sleeves then drive the connecting column and the sleeve column to move, thus enabling the plug-in column and the bearing plate to move towards or away from each other, so as to tightly fit one end of the steel structure for connection.

[0006] The steel structure auxiliary connector is characterized in that: an I-beam is fixedly connected to the bearing plate, a fastening bolt is threaded to the inner wall of the top of the I-beam, a bearing is movably connected to the bottom of the fastening bolt, a lower pressure plate is fixedly connected to the bottom of the bearing, a sliding groove is provided on the inner side of the I-beam, and sliders are fixedly connected to both sides of the lower pressure plate, with one side of the slider slidingly connected to the inner wall of the sliding groove. By rotating the fastening bolt, the lower pressure plate can be moved downward until the bottom of the lower pressure plate is tightly fitted to the top of the steel structure, thereby achieving the purpose of pressing and fixing.

[0007] The steel structure auxiliary connector is characterized in that: the plug-in column cooperates with the sleeve column through the structural design of its bottom to realize the stable movement of the plug-in column within the sleeve column.

[0008] The steel structure auxiliary connector is characterized in that: the turntable is provided with a handle to facilitate the operator to rotate the turntable.

[0009] The steel structure auxiliary connector is characterized in that: the bottom of the lower pressure plate is provided with anti-slip material to enhance the friction between the lower pressure plate and the top of the steel structure and improve the stability of the fixation.

[0010] The steel structure auxiliary connectors are characterized in that: the base, turntable, forward and reverse threaded rod, threaded sleeve, connecting column, sleeve column, and plug-in column are all made of steel, and have high strength and durability.

[0011] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a steel structure auxiliary connector. By holding the handle on the turntable and rotating it, the turntable is driven to rotate, which in turn drives the forward and reverse threaded rods to rotate. The forward and reverse threaded rods drive the two threaded sleeves to move inward, which in turn drive the connecting column to move inward, which in turn drives the sleeve column to move inward, which in turn drives the insertion column to move inward, which in turn drives the bearing plate and the steel structure to move inward until one end of the two steel structures is tightly fitted together and the movement stops. Then the subsequent connection work can be carried out, which saves time and effort and greatly improves the efficiency of connection.

[0012] Rotate the fastening bolt so that the surface and one end of the fastening bolt rotate in the inner wall of the top of the I-beam and the inner ring of the No. 1 bearing, respectively, and drive the lower pressure plate to move downward until the bottom of the lower pressure plate is tightly attached to the top of the steel structure, so as to achieve the purpose of pressing and fixing, and prevent the position from shifting during connection.

A bearing plate 10 is located on the top of the plug-in post 7, and threaded holes 8 are provided on the plug-in post 7. The plug-in post is located within the sleeve post and fixed with bolts. Rotating the turntable 2 causes the reversible threaded rod 3 to rotate, which in turn causes the two threaded sleeves 4 to move inward or outward. The threaded sleeves 4 then move the connecting post 5 and the sleeve post 6, thereby enabling the plug-in post 7 and the bearing plate 10 to move towards or away from each other, tightly fitting one end of the steel structure for connection.

[0020] Furthermore, an I-beam frame 11 is fixedly connected to the bearing plate 10. A fastening bolt 12 is threadedly connected to the inner wall of the top of the I-beam frame 11. A bearing 13 is movably connected to the bottom of the fastening bolt 12. A lower pressure plate 14 is fixedly connected to the bottom of the bearing 13. A sliding groove is provided on the inner side of the I-beam frame 11. Slider blocks are fixedly connected to both sides of the lower pressure plate 14. One side of the slider is slidably connected to the inner wall of the sliding groove. By rotating the fastening bolt 12, the lower pressure plate 14 can be moved downward until the bottom of the lower pressure plate 14 is tightly fitted with the top of the steel structure, thus achieving the purpose of pressing and fixing.

[0021] Furthermore, the insertion post 7, through its bottom structural design, cooperates with the sleeve post 6 to achieve stable movement of the insertion post 7 within the sleeve post 6.

[0022] Furthermore, the turntable 2 is equipped with a handle to facilitate the operator to rotate the turntable 2.

[0023] Furthermore, the bottom of the lower pressure plate 14 is provided with anti-slip material to enhance the friction between the lower pressure plate 14 and the top of the steel structure and improve the stability of the fixation.

[0024] Furthermore, the base 1, turntable 2, forward and reverse threaded rod 3, threaded sleeve 4, connecting post 5, sleeve post 6, and plug post 7 are all made of steel, possessing high strength and durability.

[0025] In use, hold the handle on the turntable and rotate it. The handle drives the turntable to rotate, which in turn drives the forward and reverse threaded rods to rotate. The forward and reverse threaded rods drive the two threaded sleeves to move inward, which in turn drives the connecting column to move inward, which in turn drives the sleeve column to move inward, which in turn drives the insertion column to move inward, which in turn drives the bearing plate and steel structure to move inward until one end of the two steel structures is tightly fitted together and the movement stops. Then, the subsequent connection work can be carried out.

[0026] The above are merely embodiments provided in this application and are not intended to limit this application.
