Description

Technical Field

[0001] This utility model belongs to the field of building steel structure engineering technology, specifically relating to a steel structure pipe truss connection structure. Background Technology

[0002] As a highly efficient spatial structural system, steel tubular trusses have a history dating back to the early 20th-century revolution in modern steel structures, maturing with advancements in welding technology and computer-aided design. In terms of background technology, traditional tubular truss connections primarily rely on welded joints and flange bolt connections, which suffer from technical bottlenecks such as high residual welding stress, high precision requirements for on-site construction, and insufficient joint stiffness. Currently, this technology is widely used in large-span buildings, including landmark projects such as stadiums, airport terminals, and convention centers. Its development is evolving towards prefabrication, lightweighting, and intelligent connections. New joint technologies must meet the demands of modern architecture, including rapid construction, seismic resistance, energy dissipation, and adjustability.

[0003] Traditional tubular truss connection methods generally have obvious technical defects. Welded connections are prone to heat-affected zones, which can lead to a decline in material properties, and the quality of on-site welding is greatly affected by environmental factors. Bolted connections require high-precision pre-processing, have low installation efficiency, and are prone to stress concentration in the joint area. In particular, for large-diameter tubular truss connections, existing technologies cannot simultaneously meet the dual requirements of construction convenience and joint stiffness. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure pipe truss connection structure, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steel structure tubular truss connection structure, comprising,

[0007] The mounting mechanism includes a mounting shell, a fixing plate fixedly installed on the inner wall of the mounting shell, and threaded frustums fixedly installed on both sides of the fixing plate.

[0008] The connecting mechanism includes a transmission plate threadedly connected to the surface of the threaded frustum, a reserved hole provided on the surface of the transmission plate, an actuating assembly provided on the surface of the transmission plate, a linkage assembly provided on the surface of the actuating assembly, and a transmission assembly provided on the surface of the linkage assembly.

[0009] As a preferred embodiment of this utility model, the jacking assembly includes a bottom cylinder fixedly installed on the surface of the transmission plate, a top spring fixedly installed on the inner wall of the bottom cylinder, a top cylinder fixedly installed at the end of the top spring, and a connecting ring fixedly installed at the end of the top cylinder.

[0010] As a preferred embodiment of this utility model, the linkage component includes a limiting block fixedly installed on the side wall of the connecting ring, and a moving rod slidably connected to the inner wall of the limiting block.

[0011] As a preferred embodiment of this utility model, the linkage assembly further includes a tension spring fixedly installed on the side wall of the moving rod, and a transmission block fixedly installed at the end of the moving rod.

[0012] As a preferred embodiment of this utility model, the linkage assembly includes a rack fixedly installed on the side wall of the moving rod, and a transmission gear meshing on the surface of the rack.

[0013] As a preferred embodiment of the present invention, the transmission assembly further includes a connecting rod fixedly installed on the side wall of the transmission gear, and a drive gear fixedly installed at the end of the connecting rod.

[0014] As a preferred embodiment of the present invention, the transmission assembly further includes a toothed abutment that meshes with the surface of the drive gear, and a slide rail that is slidably connected to the inner wall of the toothed abutment.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: through the internal and external bidirectional locking mechanism, the installation process is simplified while the load-bearing capacity and stability of the connection node are improved. The rotation drive setting of the mounting shell and the threaded frustum, combined with the mechanical transmission of the linkage component, makes the connection ring more stable under the elastic support of the top spring. Meanwhile, the transmission system of rack and pinion drives the toothed abutment block to move in the opposite direction, realizing the rigid clamping of the outer wall of the truss and forming a composite constraint of internal and external coordination. This not only solves the problems of cumbersome construction and stress concentration in traditional welding or bolt connections, but also the modular design can adapt to the connection requirements of trusses with different pipe diameters. It has outstanding advantages such as convenient installation, excellent seismic performance, and reusability. It is particularly suitable for the rapid construction and reliable connection of large-span spatial steel structure projects. Attached Figure Description

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a steel structure tubular truss connection structure, including,

[0027] The mounting mechanism 100 includes a mounting shell 101, a fixing plate 102 fixedly installed on the inner wall of the mounting shell 101, and threaded frustums 103 fixedly installed on both sides of the fixing plate 102.

[0028] The connecting mechanism 200 includes a transmission plate 201 threadedly connected to the surface of the threaded frustum 103, a reserved hole 202 provided on the surface of the transmission plate 201, a jacking assembly 203 provided on the surface of the transmission plate 201, a linkage assembly 204 provided on the surface of the jacking assembly 203, and a transmission assembly 205 provided on the surface of the linkage assembly 204.

[0029] The jacking assembly 203 includes a bottom cylinder 203a fixedly mounted on the surface of the transmission plate 201, a top spring 203b fixedly mounted on the inner wall of the bottom cylinder 203a, a top cylinder 203c fixedly mounted on the end of the top spring 203b, and a connecting ring 203d fixedly mounted on the end of the top cylinder 203c.

[0030] Specifically, the bottom cylinder 203a, top spring 203b, and top cylinder 203c are designed to facilitate the movement of the connecting ring 203d. When the connecting ring 203d is subjected to pressure, the top spring 203b provides a force in the opposite direction to the connecting ring 203d, ensuring the stability of the connecting ring 203d when connected to the truss.

[0031] The linkage assembly 204 includes a limiting block 204a fixedly installed on the side wall of the connecting ring 203d, and a moving rod 204b slidably connected to the inner wall of the limiting block 204a. The linkage assembly 204 also includes a tension spring 204c fixedly installed on the side wall of the moving rod 204b, and a transmission block 204d fixedly installed at the end of the moving rod 204b.

[0032] Furthermore, the linkage component 204 is provided with four sets of evenly distributed threads on the surface of the connecting ring 203d, and the inner wall of the transmission block 204d is provided with threads. The threads spliced ​​by the four transmission blocks 204d engage with the threads on the surface of the threaded frustum 103.

[0033] Preferably, the linkage assembly 204 includes a rack 205a fixedly mounted on the side wall of the moving rod 204b, and a transmission gear 205b meshing with the surface of the rack 205a. The transmission assembly 205 also includes a connecting rod 205c fixedly mounted on the side wall of the transmission gear 205b, and a drive gear 205d fixedly mounted on the end of the connecting rod 205c. The transmission assembly 205 also includes a toothed abutment 205e meshing with the surface of the drive gear 205d, and a slide rail 205f slidably connected to the inner wall of the toothed abutment 205e.

[0034] It should be noted that the slide rail 205f is fixedly connected to the inner wall of the mounting housing 101, and the transmission gear 205b is connected to the surface of the connecting ring 203d through a bearing.

[0035] In use, the two ends of the truss to be spliced ​​are inserted into the two ends of the mounting shell 101, abutting against the fixing plate 102, and inserted into the inner wall of the connecting ring 203d. Rotating the mounting shell 101 causes the fixing plate 102 to rotate, which in turn causes the threaded frustum 103 to rotate. The limiting block 204a ensures the direction of movement of the connecting rod 205c. The tension spring 204c pulls the connecting rod 205c towards the threaded frustum 103, which in turn causes the moving block to move towards the fixing plate 102. The bottom cylinder 203a cooperates with the top spring 203b and the top cylinder 203. c pushes the connecting ring 203d, and the connecting block is simultaneously supported by the threaded frustum 103. The connecting block abuts against the inner wall of the connection. When the connecting rod 205c moves, it drives the rack 205a to move. The rack 205a drives the transmission gear 205b to rotate. The transmission gear 205b drives the connecting rod 205c to rotate. The connecting rod 205c drives the drive gear 205d to rotate. The drive gear 205d drives the toothed abutment block 205e to move. The toothed abutment block 205e moves in the opposite direction to the rack 205a. The toothed abutment block 205e abuts against the outer wall of the connection, fixing the connection.

[0036] In summary, the efficient and stable connection of the truss is achieved through the coordinated use of the installation mechanism 100 and the connection mechanism 200. The threaded engagement of the threaded frustum 103 and the transmission plate 201, combined with the elastic support of the jacking component 203, allows the connecting ring 203d to automatically adjust and maintain stable contact under pressure via the jacking spring 203b. The limiting block 204a and tension spring 204c in the linkage component 204 ensure that the transmission block 204d is always tightly engaged with the threaded frustum 103, thereby driving the transmission block 204d to move radially when the mounting shell 101 is rotated, so that the connecting ring 203d is firmly pressed against the inner wall of the truss. At the same time, the coordinated use of the rack 205a, the transmission gear 205b, and the drive gear 205d drives the toothed abutment block 205e to move in the opposite direction, achieving synchronous clamping of the outer wall of the truss, forming a two-way locking mechanism, which greatly improves the rigidity and deformation resistance of the connection node. The device is easy to install and can adapt to the connection requirements of different specifications of tubular trusses, and has high engineering practicality and promotion value.
