Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a disassembly and assembly mechanism and a load-bearing truss. Background Art

[0002] The truss structure is made up of rods connected at both ends by hinges. The advantage is that the rods can withstand greater tension and pressure, which can give full play to the role of materials, save materials, and reduce the weight of the overall structure. Trusses are indispensable when arranging some large booths and performances that need to bear weight. Trusses are very strong in structure and are not easy to break or deform.

[0003] During the construction of industrial plants, it was found that the interior of the plant had reserved space for laying high-voltage and low-voltage cables, installing bridges, and other spaces for installing related structures. However, when installing the trusses, the weight of the trusses themselves exceeded the support range of manpower, so cranes or other related equipment were required to assist in the installation of the trusses. During the installation and fixing process, the main trusses were unstable, making installation difficult. For this reason, we proposed a disassembly and assembly mechanism and a load-bearing truss. Utility Model Content

[0004] In view of the inconvenience of truss installation in the prior art, the utility model provides a disassembly and assembly mechanism and a load-bearing truss, which have the advantages of convenient installation and disassembly.

[0009] Preferably, a mounting groove corresponding to the threaded rod and the fixing rod is provided inside the lower limit member, the threaded rod is detachably connected to the inside of the groove, and the position of the lower limit member can be adjusted when the threaded rod rotates.

[0010] Preferably, a hole is opened inside the adjusting rod, a fixing bolt is arranged inside the hole, a mounting hole corresponding to the fixing bolt is opened inside the connecting rod, the fixing bolt is installed inside the mounting hole, and the fixing bolt can fix the adjusting rod and the connecting rod.

[0011] A load-bearing truss comprises a main truss, wherein a cross beam is fixedly connected to the outside of the main truss, a longitudinal beam is fixedly connected to the outside of the main truss, and an upper limit piece is clamped on the outside of the main truss.

[0012] Beneficial effects:
