[0002] A truss is a structure made up of rods connected to each other at both ends. A truss is a plane or spatial structure composed of straight rods, generally with triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams. Trusses can be welded or assembled, but since assembled trusses have strong flexibility and reusability, assembled trusses are currently the mainstream. However, existing assembled trusses require the use of more bolts, nuts and other accessories during assembly. Moreover, the models and sizes of the accessories used for different parts are also different, which not only makes it easy to use the wrong accessories, but also leads to low assembly efficiency.

[0021] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0022] See also Figure 1-Figure 5 The assembled building truss of the utility model comprises two side bars 1 each connected by a plurality of suspension tubes 2. Two adjacent suspension tubes 2 in each side bar 1 are detachably connected by a connecting piece 3. A connecting vertical bar 4 is provided between the connecting pieces 3 of the two side bars 1, and a supporting diagonal bar 5 is provided between the ends of the two adjacent connecting vertical bars 4 in a diagonal structure, and the supporting diagonal bar 5 is detachably mounted on the connecting vertical bar 4 through the connecting piece 3.

[0023] The assembled building truss can divide the square frame composed of the hanging pipe 2 and the connecting vertical rod 4 into a triangular structure by setting the supporting diagonal rod 5, thereby ensuring the stability of the truss. The supporting diagonal rod 5, the hanging pipe 2 and the connecting vertical rod 4 are connected by the connecting piece 3, realizing the convenient disassembly and assembly of the truss.

[0024] In this embodiment, a through hole 1 is provided in the connecting member 3, and a screw 8 is fixedly provided at the end of one of the two adjacent suspension tubes 2, and a connecting block 9 is welded inside the end of the other of the two adjacent suspension tubes 2. A threaded hole is provided in the connecting block 9, and the screw 8 is screwed into the threaded hole, thereby realizing a detachable connection between the suspension tube 2 and the connecting member 3.

[0025] Moreover, when assembling the hanging pipe 2, the installation of the hanging pipe 2 to be installed can be completed by aligning the connecting block 9 end of the hanging pipe 2 to be installed with the screw rod 8 of another hanging pipe 2, and then rotating and tightening the hanging pipe 2 to be installed. In addition, the process does not require workers to carry and install additional accessories, which greatly improves the convenience of work.

[0026] Preferably, a positioning block 6 is welded in the inner hole of one end of the suspension tube 2, and a square block 7 is fixed to one side of the positioning block 6. The positioning block 6, the square block 7 and the screw rod 8 are an integrated structure. The screw rod 8 is fixed to one side of the square block 7.

[0027] In this embodiment, a square hole connected to the through hole 1 is provided in the connecting member 3, and the square hole matches the square block 7, and the square block 7 is inserted into the square hole. By setting the square block 7, the suspension pipe 2 can be effectively positioned to avoid the suspension pipe 2 from rotating during installation or use of the truss, thereby greatly improving the reliability of the truss.
