Assembly type steel-concrete composite structure residential system and construction method thereof

Abstract

The invention discloses an assembly type steel-concrete composite structure residential system. In the assembly type steel-concrete composite structure residential system, mounting holes are formed inoutside flanges of end cross beams at the upper ends or the lower ends of multilayer of prefabricated steel reinforced concrete shear walls; connecting steel plate seats are arranged at one ends without cross beams, and mounting holes are formed in the connecting steel plate seats and correspond to the mounting holes in the outside flanges of the end cross beams in position; and processing slotsfor installing bolts or nuts are formed in parts, corresponding to the mounting holes in the flanges of the outer sides of the end cross beams in position, of prefabricated concrete. According to theassembly type steel-concrete composite structure residential system, the factory prefabrication degree is high, and wet work on site is less. Fabricated structural steel concrete shearing walls as well as the fabricated structural steel concrete shearing walls and peripheral steel beams are in bolted connection, and the on-site construction speed is high. The assembly type steel-concrete compositestructure residential system has good seismic performance, can be applied to areas with high seismic intensity, and is suitable for large heights.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled steel-concrete composite structure housing system and a construction method thereof. Background technique [0002] In residential buildings in our country, the cast-in-place reinforced concrete shear wall residential structure has been widely used. The cast-in-place reinforced concrete shear wall structure residence has: (1) The structure and enclosure are integrated, and the shear wall serves as both a structural component and an enclosure component; (2) The structure and insulation are integrated, and the concrete itself is a thermally inert material. Good thermal insulation performance; (3) The structure and protection are integrated, the steel bars are covered in concrete, no anti-corrosion and fire prevention, and maintenance-free. (4) The structure and decoration are integrated, and the concrete can be used directly as a decorative surface. (...

Problems solved by technology

However, cast-in-place reinforced concrete shear wall structure residences still exist: there are many wet operations on site, the degree of assembly is not high, waste of resources, environmental pollution, and the inability to achieve four sections and one environmental protection, etc., do not meet the development needs of the modernization of the construction industry

[0003] The prefabricated reinforced concrete shear wall structure system has the advantages of factory prefabrication, on-site assembly construction, less waste of resources, and less environmental pollution. Many, low construction efficiency, high cost, etc.

The steel bars in the prefabricated reinforced concrete shear wall structure are often connected by grouting sleeves. This connection method requires high processing precision for the prefabricated reinforced concrete shear walls. If the position of the steel bars is slightly deviated, it will be difficult for the on-site steel bars to penetrate into the sleeves; at the same time Due to the large number of steel bars in the shear wall and the high-altitude operation, the centering of the upper and lower prefabricated reinforced concrete shear walls and the on-site construction of the steel bar connection are relatively difficult; After the sleeve is reserved for the force wall, high-strength grouting material needs to be poured into the sleeve. Since this process is a concealed project and most of the on-site operators are ordinary migrant workers, it is difficult to guarantee the construction quality of the steel sleeve grouting. Difficult to remedy, there are certain security risks
