Description

Technical Field

[0001] The invention relates to the technical field of building steel structure roof trusses, and in particular to a multi-directional assembled building steel structure roof truss. Background Art

[0002] The multi-directional prefabricated steel structure roof truss is a new type of building structure that combines the strength and flexibility of steel structure with the convenience and efficiency of prefabricated buildings. The roof truss components can be assembled in multiple directions, providing greater flexibility to adapt to different building designs and functional requirements. Modular design: The use of standardized and modular components facilitates large-scale production and rapid on-site assembly. Lightweight and high-strength: The use of high-strength steel reduces the deadweight while ensuring the stability and load-bearing capacity of the structure.

[0003] Prefabricated design reduces on-site construction time, allows for quick assembly and disassembly, and greatly improves construction efficiency. Quality control: Producing components in the factory enables higher quality control and reduces uncertainty in on-site construction. Reducing construction waste: The modular construction method reduces waste and construction waste during construction, meeting the requirements of sustainable development. Energy saving and environmental protection: Steel structure materials are recyclable, and prefabricated buildings reduce resource consumption and reduce the impact on the environment. Design flexibility: It can adapt to a variety of building forms and functional requirements and can be used in a variety of scenarios such as industry, commerce, and civil use.

[0004] Existing prefabricated steel structure roof trusses are connected by high-strength bolts during installation, which is convenient for on-site assembly and disassembly. It is necessary to ensure that the design of the connection nodes meets the strength and stiffness requirements. During the use of the building, the vibration caused by wind loads, equipment operation and personnel activities may cause the bolts to loosen. The increase and decrease of temperature will cause the material to expand and contract, affecting the tightening state of the bolts.

[0005] The existing prefabricated steel structure roof trusses are inconvenient to regularly check and tighten the nuts on the bolts automatically installed on the top of the roof when in use, resulting in the nuts becoming loose and not being discovered and handled in time, which may lead to a decrease in the strength of the connection parts, thereby affecting the stability and safety of the entire roof truss.
