Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to an eight-column and sixteen-beam connection node of a plug-in type three-dimensional wood structure module. Background Art

[0002] In recent years, China's wooden structures have shown a rapid development trend with their advantages of environmental protection, sustainability and cultural heritage. Wooden structures have been promoted and applied in urban renewal, tourist attractions and residential areas, becoming an important part of modern architecture. Wooden structures are prefabricated and assembled, which can avoid wet operations and are not restricted by seasons. This feature ensures construction quality and speed while reducing environmental pollution and resource consumption, making it an important choice for sustainable development.

[0003] At present, there have been many studies on the joints of wooden beams and columns. These studies are committed to improving the strength and stability of the connection and promoting the development of modern wooden structures. For example, the utility model patent "Assembled wooden frame beam-column connection node" provides a solution with high strength, simple production and strong applicability, but the components such as the stiffening L-shaped connectors used in it protrude beyond the surface of the beams and columns, making the junction of the structure not a 90° right angle, which causes inconvenience to other functional and decorative construction. The invention patent "A prefabricated steel-wood composite structure and its assembly method" solves the problem of wooden beam-column node connection by prefabricated steel sleeves and mortise and tenon structures. However, the heavy steel sleeves used increase the structural load, and the mortise and tenon structure is relatively complex, which is prone to problems such as pulling out the tenon, breaking the tenon and damaging the mortise. The invention patent "A layered assembled steel-wood composite module building and its assembly method" solves the problems of low quality and low assembly efficiency of wooden structure construction projects and shortens the construction period. However, this method is limited to the assembly construction of one-dimensional rods and two-dimensional plates, and interior decoration is still required after the structure is completed.

[0004] In general, existing wooden structures require complex processing at the beam-column joints, as well as heavier steel components to enhance the stability of the joints, and do not solve the structural problem of using a small amount of steel components to simultaneously solve the horizontal lateral force and vertical pull-out resistance. The existing prefabricated construction methods can only realize the prefabricated construction of one-dimensional rods and two-dimensional panels, and do not solve the rapid construction of three-dimensional modular structures and integrated interiors. Therefore, there is an urgent need to design a new type of wooden beam-column node that can be prefabricated in the factory (including steel components and wooden beams and columns) and can be quickly assembled on site; at the same time, it can realize a complex node that can realize the internal connection of independent units of three-dimensional modules and the connection between three-dimensional modules. Based on the above technical problems, the present invention provides a plug-in type three-dimensional wooden structure module eight-column and sixteen-beam connection node. Summary of the invention
