Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an installation device for a large-span steel structure truss. Background Art

[0002] A truss is a supporting beam structure made of rods connected by welding, riveting or bolts. This structure consists of straight rods and usually has a plane or spatial structure of triangular units. The truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material.

[0003] When a steel structure faces a large-span design, installing the truss becomes a necessary step to ensure its load-bearing and stability. However, due to the lack of an effective positioning structure during the installation process, workers often face problems with truss misalignment and tilt, which greatly reduces the overall stability and load-bearing capacity of the steel structure frame. Therefore, it is urgent to design a positioning and installation device for large-span steel structure trusses that can accurately position the trusses during installation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides the following technical solutions: an installation device for a large-span steel structure truss, comprising a first steel structure bracket and a second steel structure bracket, a triangular truss for reinforcement is arranged between the first steel structure bracket and the second steel structure bracket, a supporting cylinder is welded to the top inner wall of the triangular truss, a fixing mechanism is movably clamped on the left and right sides of the first steel structure bracket, a first clamping positioning plate is welded to the top left end of the fixing mechanism, a second clamping positioning plate is welded to the top right end of the fixing mechanism, a U-shaped positioning plate is movably hinged at the bottom of the first clamping positioning plate, the supporting cylinder is located in the U-shaped groove of the U-shaped positioning plate, a fixing magnet is arranged at the bottom of the second clamping positioning plate, and the U-shaped positioning plate and the fixing magnet are connected by magnetic force.

[0005] As an improvement of the above technical solution, the fixing mechanism includes a first docking slot block and a second docking slot block, the first docking slot block is movably connected to the left side of the first steel structure bracket, the second docking slot block is movably connected to the right side of the first steel structure bracket, a first fixed connecting plate is welded to the bottom of the first docking slot block, a second fixed connecting plate is welded to the bottom of the second docking slot block, the first fixed connecting plate and the second fixed connecting plate are threadedly connected with a bidirectional threaded rod, a first arc fixing plate is fixedly installed on the top of the first docking slot block, the top of the first arc fixing plate is welded to the left side of the first clamping and positioning plate, a second arc fixing plate is fixedly installed on the top of the second docking slot block, the top of the second arc fixing plate is welded to the right side of the second clamping and positioning plate, and the cooperation between the fixing mechanisms drives the first clamping and positioning plate and other structures to fix and position the triangular truss.

[0006] As an improvement of the above technical solution, three corners of the triangular truss are provided with stabilizing steel plates to facilitate welding of the triangular truss.

[0007] As an improvement on the above technical solution, the front and rear ends of the first clamping positioning plate and the second clamping positioning plate close to the triangular truss are both arc-shaped, so that the first clamping positioning plate and the second clamping positioning plate can position the triangular truss when the first docking slot block and the second docking slot block slide.

[0008] As an improvement of the above technical solution, the first arc fixing plate and the second arc fixing plate are offset from the supporting cylinder to facilitate the U-shaped positioning plate to swing to position and fix the supporting cylinder.

[0009] The beneficial effects of the utility model are as follows: the cooperation between the fixing mechanisms drives the first clamping and positioning plate and the second clamping and positioning plate to fix and position the left and right sides of the triangular truss, and the front and rear sides of the triangular truss and the supporting cylinder are fixed and positioned by clamping the U-shaped positioning plate with the supporting cylinder, so that the triangular truss and the supporting cylinder are positioned and fixed in multiple directions, and the dislocation and tilting during the welding process of the triangular truss and the supporting cylinder are prevented, thereby improving the supporting effect of the triangular truss and the supporting cylinder on the steel structure, and also improving the overall stability and load-bearing capacity of the steel structure frame.

[0018] Specifically, the fixing mechanism includes a first docking card slot block 4 and a second docking card slot block 41. The first docking card slot block 4 is movably connected to the left side of the first steel structure support 1, and the second docking card slot block 41 is movably connected to the right side of the first steel structure support 1. A first fixed connecting plate 42 is welded to the bottom of the first docking card slot block 4, and a second fixed connecting plate 43 is welded to the bottom of the second docking card slot block 41. The first fixed connecting plate 42 and the second fixed connecting plate 43 are threadedly connected with a bidirectional threaded rod 44. A first arc fixing plate 45 is fixedly installed on the top of the first docking card slot block 4, and the top of the first arc fixing plate 45 is welded to the left side of the first clamping and positioning plate 5. A second arc fixing plate 46 is fixedly installed on the top of the second docking card slot block 41, and the top of the second arc fixing plate 46 is welded to the right side of the second clamping and positioning plate 51.

[0019] In this embodiment, the cooperation between the fixing mechanisms drives the first clamping and positioning plate 5 and other structures to fix and position the triangular truss 3 .

[0020] Specifically, three corners of the triangular truss 3 are provided with stabilizing steel plates.

[0021] In this embodiment, it is convenient to weld the triangular truss 3 .

[0022] Specifically, both front and rear ends of the first clamping and positioning plate 5 and the second clamping and positioning plate 51 close to the triangular truss 3 are designed in an arc shape.

[0023] In this embodiment, the first clamping and positioning plates 5 and the second clamping and positioning plates 51 position the triangular truss 3 when the first docking card slot block 4 and the second docking card slot block 41 slide.

[0024] Specifically, the first arc fixing plate 45 and the second arc fixing plate 46 are offset from the supporting cylinder 31 .

[0025] In this embodiment, the U-shaped positioning plate 52 can be swung to position and fix the supporting cylinder 31 .

[0026] When in use, place the triangular truss 3 and the supporting column 31 between the first steel structure support 1 and the second steel structure support 2, place the first docking card slot block 4 on the left side of the steel structure and the second docking card slot block 41 on the right side of the steel structure, and connect the first fixed connecting plate 42 and the second fixed connecting plate 43 to the two-way threaded rod 44 through threads. Initially, hold the first docking card slot block 4 and rotate the two-way threaded rod 44 to gradually approach the first fixed connecting plate 42 and the second fixed connecting plate 43, and the first fixed connecting plate 42 and the second fixed connecting plate 43 drive the first docking card slot block 4 and the second docking card slot block 41 to gradually As the first and second docking card slot blocks 4 and 41 gradually approach each other, they gradually approach and are stuck on the first steel structure support 1.

During the movement of the first clamping positioning plate 5 and the second clamping positioning plate 51 to the position between the first steel structure support 1, the triangular truss 3 and the supporting column 31 are positioned to prevent the triangular truss 3 and the supporting column 31 from tilting. The U-shaped positioning plate 52 is rotated at the same time, and the U-shaped positioning plate 52 is swung to the right to be magnetically adsorbed by the fixed magnet 53. The front and rear sides of the supporting cylinder 31 are fixed and positioned by the U-shaped positioning plate 52.
