Description

Technical Field

[0001] The present invention belongs to the technical field of modular housing design and construction, and particularly relates to a roof beam of a prefabricated house. Background Art

[0002] With the development of prefabricated buildings, the demand for prefabricated building products is increasing. Usually, prefabricated buildings are made into semi-finished modules and then transported to the site for assembly. Among them, the integrated roof is usually made into different functional modules for easy transportation, installation, demolition, and reuse. The integrated roof mainly includes a roof beam, a roof skeleton, a top beam, and a ceiling. Since most of them are made of light steel keels, they are light in weight, low in cost, and have the advantage that each module can be prefabricated in batches at the same time. The roof beam is mainly fixed to the beam and supports the roof panel. In the prior art, the roof beam used for modular housing construction mainly uses a truss structure. Although it can meet the requirements of structural stability to a certain extent, its connection and expansion performance have great limitations, which is not convenient for fixing with various structural members during on-site construction. Moreover, the local structure of the connection point has not been optimized, and deformation is likely to occur during long-term use and under load, affecting the roof safety. Therefore, it is necessary to improve the existing roof beam structure. Summary of the Invention
