Description

Technical Field

[0001] The invention relates to the technical field of structural engineering, and in particular to a lattice integral modular load-bearing-energy dissipation node and a building structure. Background Art

[0002] Modular buildings can use modern industrial technology to mass-produce highly integrated space modules on the assembly line. After the completion of the basic engineering construction, they can be quickly assembled on site to form a complete modular structural system. Because steel structure materials have high ductility, light weight and high strength, and no wet operation on site, they are suitable for modular buildings. Highly integrated steel modules have the advantages of fast on-site construction speed, flexible assembly, low on-site labor requirements, etc., and have broad market application prospects.

[0003] The reliable connection between stacked modules determines the overall performance and seismic resistance of the module structure. In the existing stacked module structure, the module structure is a three-dimensional space structure formed by four ceiling beams, four floor beams and four module columns, which has both ceiling and floor. In addition, the beams and columns in the module structure are mostly traditional I-shaped and square steel tube sections. When connecting between modules, especially when connecting between 4 and 8 modules, more operating platforms are required. In order to achieve better overall performance, the stacked module structure needs to directly connect the upper and lower module columns to realize the transmission of force in the vertical direction. At the same time, there must be horizontal connections between the modules to enhance the integrity of the structure and improve the ability to resist wind loads and horizontal earthquakes.

[0004] In summary, the existing stacked module structure needs to connect four traditional beams, eight traditional columns, or even eight traditional beams and sixteen traditional columns at the nodes at the same time, which causes the module beams and columns to fail to fully exert the material properties and increases the cost.

[0016] In general, the present invention has the following advantages: 1. The present invention forms a frame structure of various structures by splicing upper steel modules, lower steel modules, plane modules and module columns. It has self-bearing and self-stabilizing properties, and can bear decoration work to achieve factory-based high integration. The beams and columns in the new structure formed after the connection is completed form an integral four-limb lattice column and a double-limb lattice beam by connecting the gusset plates, so that each limb can give full play to its material properties. Compared with conventional modular nodes, the lattice integral modular load-bearing and energy-dissipating node proposed in the present invention can give full play to the material properties.

The industrialization of construction requires full use of existing industrialization achievements to reduce the dependence on manual labor in each link. In the present invention, the standardization of steel modules is used to achieve assembly line mass production and reduce costs.

The gaps between the lattice beams of the lattice integral modular load-bearing-energy dissipation node can be used as operating holes to realize the fixed connection between the flange in the load-bearing-energy dissipation connection part, the flange of the plane reinforcement module column, and the flange of the reinforcement column; bolt holes can be set on the horizontal connecting plate, and correspond one-to-one with the bolt holes on the stiffening plates on the adjacent four open module columns, so as to realize the high-strength bolt fixed connection; bolt holes can be set on the vertical connecting plate, and correspond one-to-one with the bolt holes on the flanges of the adjacent four open module columns, so as to realize the high-strength bolt fixed connection; the high-strength bolt connection can greatly improve the assembly rate, reduce the on-site labor demand, and there is no wet operation on site, and it can realize the rapid disassembly and maintenance between modules and the reuse of the modules after disassembly.
