Modular prefabricated steel-concrete combination frame structure

Abstract

The invention discloses a modular prefabricated steel-concrete combination frame structure which is composed of a prefabricated combination frame module and a modular connecting piece. The prefabricated combination frame module is composed of pre-embedded concrete-filled steel pipe prefabricated columns, pre-embedded profile steel concrete laminated beams and a concrete laminated plate. Steel pipes of the pre-embedded concrete-filled steel pipe prefabricated columns and profile steel of the pre-embedded profile steel concrete laminated beams are connected in a welded or bolted mode at joints.The concrete laminated plate is placed on protective layer concrete of the pre-embedded profile steel concrete laminated beams. Laminated layer concrete and concrete at the joints of the pre-embeddedconcrete-filled steel pipe prefabricated columns and the pre-embedded profile steel concrete laminated beams are poured jointly. The modular connecting piece is formed by welding of a connecting steelplate and high-strength steel pipes. According to the modular combination frame structure, the technical advantages of modular prefabrication can be given into full play, the seismic performance requirement can also be met, the technical and economic benefits are obvious, and the modular prefabricated steel-concrete combination frame structure is applicable to a seismic zone frame structure.

Description

technical field [0001] The invention relates to a modular prefabricated steel-concrete composite frame structure, which belongs to the technical field of assembled concrete frame structures in construction engineering. Background technique [0002] Modular building technology has realized the expansion of prefabrication technology from 2D to 3D, further improved the efficiency of prefabrication, has obvious technical economy, and has become one of the important directions for the development of prefabricated buildings in my country. The current mainstream modular buildings mainly use steel structures, which are generally used in commercial buildings, such as hotels, parking lots, etc. The problems faced by steel structures such as fire protection, heat preservation, and comfort limit their wide application; at the same time, the connections between modules are general. It is connected by welding or bolts, and due to the inherent influence on the construction of the nodes whe...

Problems solved by technology

The current mainstream modular buildings mainly use steel structures, which are generally used in commercial buildings, such as hotels, parking lots, etc. The problems faced by steel structures such as fire protection, heat preservation, and comfort limit their wide application; at the same time, the connections between modules are general. It is connected by welding or bolts, and due to the inherent influence on the construction of the nodes when the modules are assembled on site, the modules cannot be fully connected, and the nodes are weaker than the modules themselves. Therefore, the existing technology generally designs the modules to only bear vertical loads When applied in earthquake areas, cast-in-place core tubes must be used, which greatly limits its application technically.
