Assembled profile steel concrete shear wall structure and its preparation and installing method

Abstract

The invention discloses an assembled profile steel concrete shear wall structure. An installing hole is arranged on an outside wing edge of the end cross beam at the upper end or lower end of the assembled profile steel concrete shear wall structure; one end without the cross beam is provided with a connecting steel plate base, and the installing hole is also arranged on the connecting steel platebase; the installing hole is corresponding to that on the outside wing edge of the end cross beam; the place corresponding to the installing hole on the outside wing edge of the prefabricated concrete and end cross beam is provided with a technical slot for installing bolts or nuts. The assembled profile steel concrete shear wall structure is high in factory prefabrication degree and less in field wet work; full bolt connection methods are applied to the middle of the assembled profile steel concrete shear walls and between the assembled profile steel concrete shear wall and surrounding steelbeams; the field construction speed is quick, the anti-seismic property is good; the assembled profile steel concrete shear wall structure is applicable to the area with high seismic intensity, and the structure applicable height is big.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled steel concrete shear wall structure and a preparation and 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 grouting sleeve is reserved for the force wall, high-strength grouting material needs to be poured into the sleeve. Since this process is a hidden project and most of the on-site operators are ordinary migrant workers, it is often difficult to guarantee the construction quality of the steel sleeve grouting. It is difficult to remedy, and there is a certain security risk
