[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a steel structure truss beam with high bearing capacity, including a support beam 1 and a support assembly. The support beam 1 is arranged in two groups symmetrically up and down. The support assembly is arranged between the two groups of support beams 1. The support assembly includes a triangular frame 2, a positioning block 3, an elastic member, and a clamping block 4. Positioning blocks 3 are arranged at one end far from the center of the triangular frame 2 at the three corners of the triangular frame 2. A connection groove adapted to the positioning block 3 is arranged at one end of the support beam 1 close to the triangular frame 2. Moving grooves are arranged on the left and right sides of the positioning block 3. The elastic member and the clamping block 4 are arranged in the moving grooves. A clamping groove adapted to the clamping block 4 is arranged in the connection groove. The moving groove is arranged at one end close to the opening of the connection groove. The positioning block 3 is in a T shape. A bolt 5 penetrating the positioning block 3 is arranged on the support beam 1. A nut 6 threadedly connected to the bolt 5 is further arranged in the support beam 1.

[0025] First, align the positioning block 3 of the triangular frame 2 with the connection groove on the support beam 1. Since the positioning block 3 is in a T shape, it can be conveniently inserted into the connection groove for preliminary positioning. When the positioning block 3 is inserted into the connection groove, the inclined surfaces 10 at the front and rear ends of the clamping block 4 first contact the inner wall of the connection groove. As the positioning block 3 continues to be inserted, the inner wall of the connection groove applies pressure to the inclined surface 10 of the clamping block 4, causing the clamping block 4 to compress the elastic member and retract into the moving groove. When the positioning block 3 is completely inserted into the connection groove, the clamping block 4 pops out under the action of the elastic member and snaps into the clamping groove in the connection groove. At this time, the triangular frame 2 and the support beam 1 are preliminarily connected. At this time, the screw hole of the positioning block 3 is aligned with the bolt 5. Then, pass the bolt 5 through the support beam 1 and penetrate the positioning block 3, and then threadedly connect with the nut 6 in the support beam 1. When the truss beam bears an external load, the load first acts on the upper and lower two groups of support beams 1. The support beam 1 is connected to the positioning block 3 of the triangular frame 2 through the connection groove, and the load is transmitted to the triangular frame 2. The positioning blocks 3 at the three corners of the triangular frame 2 evenly share the load, and through the cooperation of the clamping block 4 and the clamping groove and the connection of the bolt 5 and the nut 6, the load is effectively transmitted to each part of the triangular frame 2.

[0026] In this embodiment, a reinforcing rib 7 is further arranged in the support beam 1. The reinforcing rib 7 is adapted to the connection groove, and the reinforcing rib 7 ensures the strength of the support beam 1.

[0027] During actual use, the elastic member includes a spring 8 and a telescopic rod 9. The spring 8 is sleeved on the telescopic rod 9. Both ends of the spring 8 and the telescopic rod 9 are respectively connected to the movable groove and the clamping block 4. The spring 8 facilitates the reciprocating movement of the clamping block 4, and the telescopic rod 9 ensures the stability of the movement of the clamping block 4.

[0028] In this embodiment, a central vertical beam 11 is provided at the center of the tripod 2. The central vertical beam 11 at the center of the tripod 2 plays a strengthening role, can withstand forces from all directions, and disperse the load to the entire tripod 2. At the same time, the reinforcing ribs 7 in the support beam 1 can also enhance the strength and stiffness of the support beam 1 and improve its load-bearing capacity.

[0029] A gasket 12 is also provided between the nut 6 and the corresponding support beam 1. The gasket 12 between the nut 6 and the support beam 1 can increase the contact area, disperse the pressure, and prevent the nut 6 from loosening. Through the connection of the bolt 5 and the nut 6, the connection stability between the tripod 2 and the support beam 1 is further strengthened.
