Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, specifically relates to a kind of assembly mortise and tenon steel node. BACKGROUND

[0002] As a new building method, prefabricated farmhouses have received more and more attention and development in rural areas in recent years. This building method is not only an innovation of traditional building construction mode, but also an important means to improve rural housing conditions and living environment. The core of prefabricated farmhouse is to transfer a large number of on-site construction operations in traditional building methods to factories, and to transport the components of building produced in factories to the construction site for reliable connection and assembly installation. This method not only improves the quality of the building, but also greatly shortens the construction period and reduces environmental pollution at the construction site.

[0003] However, in the actual construction process, although the beam-column joint basically uses beam flange welding and web bolt connection in most cases at present, this method can ensure the safety and stability of the structure, but it also brings new problems: (1) Large amount of on-site welding: Since part of the key nodes need to be welded on site, it means that a sufficient number of professional welders must be involved. For some remote area projects, it is not easy to find experienced and skilled welders, which may cause delay in the construction period. (2) Slow construction speed: Compared with completely prefabricated components that can be directly hoisted into place and quickly fixed, on-site welding undoubtedly increases additional working time and complexity. Especially in adverse weather conditions, the efficiency of outdoor welding work will be further reduced, thereby affecting the progress of the entire project. (3) Welding quality is greatly affected by environment and worker welding level: Even the most advanced welding equipment cannot completely eliminate the influence of human factors on the quality of the final product. In particular, changes in temperature, humidity and other natural conditions in an open construction site will adversely affect the welding process; at the same time, the difference in technical level between different welders may cause the quality of welding points in the same project to be uneven, thereby affecting the safety performance of the overall structure.
