Description

Technical Field

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

[0002] In recent years, China's timber-framed architecture has experienced rapid growth, driven by its environmental, sustainable, and culturally relevant advantages. Its widespread application in urban renewal, tourist attractions, and residential areas has become a vital component of modern architecture. Timber-framed architecture utilizes prefabrication and prefabricated construction, avoiding wet work and allowing construction to proceed regardless of season. This ensures construction quality and speed while reducing environmental pollution and resource consumption, making it a key option for sustainable development.

[0003] Numerous studies have been conducted on timber beam-column joints, aiming to improve the strength and stability of these connections and driving the development of modern timber structures. For example, the utility model patent for "Assembled Timber Frame Beam-Column Joint" offers a solution that is high-strength, simple to manufacture, and highly adaptable. However, its reinforced L-shaped connectors and other components protrude beyond the beam and column surfaces, resulting in non-90° intersections and hindering the construction of other functional and decorative features. The invention patent for "A Prefabricated Steel-Wood Composite Structure and Assembly Method Thereof" addresses the issue of timber beam-column joint connections by combining prefabricated steel sleeves with a mortise and tenon joint structure. However, the heavy steel sleeves increase structural loads, and the complex mortise and tenon joint structure is prone to problems such as pullout, breakage, and joint damage. The invention patent for "A Layered Prefabricated Steel-Wood Composite Modular Building and Assembly Method Thereof" addresses the issues of low quality and assembly efficiency in timber structures, shortening construction timelines. However, this method is limited to prefabricated construction using one-dimensional rods and two-dimensional panels, requiring interior decoration 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 method can only realize the prefabricated construction of one-dimensional rods and two-dimensional plates, and does not solve the rapid construction of three-dimensional modular structures and integrated interior decoration. 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 complex nodes such as internal connections of independent units of three-dimensional modules and connections 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
