Description

Technical Field

[0001] The invention belongs to the field of modular buildings, and in particular relates to a column system of modular buildings. Background Art

[0002] Modular construction is an emerging building structure system that takes each room as a modular unit. All of them are prefabricated in the factory, transported to the site after completion, and assembled into a whole building through reliable connections.

[0003] Modular construction is an assembly technology that uses prefabricated modular components, such as walls, to assemble various houses. It is easy to construct and flexible to assemble. Modular components are prefabricated in factories, which is convenient for organizing industrial production, improving work efficiency, reducing material consumption, and being less affected by seasons. Modular construction has the characteristics of fast construction speed, good seismic performance, large usable area, light building weight, simple construction, flexible assembly, low labor and material consumption, and modular components that can be designed. Therefore, it has great application value in urban construction.

[0004] In addition to load-bearing walls and beam structures, a complete house also has columns for controlling the stress points of the room. More importantly, the traditional model of floors is mainly reinforced concrete structure, which takes a long time to construct and maintain concrete, and the reinforced concrete has poor seismic performance.

[0005] For example, Chinese patent publication number CN201821704810.5 is a modular building and column welding mold based on a column welding mold. The total length of the column and the connecting plate of each module unit is a standardized length. The standard length of the welding structure corresponds to the welding length specified by the column welding mold. The column is a hollow steel pipe, which is horizontally placed on the base of the column welding mold, and the radial position of the column on the mold is fixed; the first end of the inner lining plate is sleeved in the hollow part of the column; the second end is reserved on the outside of the column, and the edge of the second end is kept parallel to the outer edge of the column fracture, which is used to support the weld; the connecting plate is placed at both ends of the column, and is relatively fixed with the end plate position at both ends of the mold, and is welded to the second end of the inner lining plate and the outer edge of the column fracture.

[0006] Another example is a modular building with Chinese patent publication number CN201620230685.3, which is assembled from long metal plates. The long metal plates are cut to form columns, beams and floor slabs for modular buildings. The columns, beams and floor slabs are connected to each other to form a modular building. The material of the long metal plates is a metal honeycomb panel, including a honeycomb core and two panels that sandwich the honeycomb core. The present invention combines floor slabs, beams and columns of appropriate sizes into separate building units; the shape and size of the building unit can be set according to the builder's preference. In addition, multiple building units of different sizes and shapes can form buildings of different shapes to meet the needs of different consumers.

[0007] Therefore, there is an urgent need to provide a modular building column system that is simple to prepare and operate, has high installation efficiency, and has good seismic resistance. Summary of the invention
