Fabricated composite shear wall and connection structure with steel beams and floors thereof

Abstract

The invention discloses a fabricated composite shear wall and a connection structure with steel beams and floors thereof. The connection between edge members and walls is realized by cast-in-situ concrete poured in cavities of steel pipes of the edge members, the connection structure is simple and reliable, the quality of field construction of the shear wall can be guaranteed, and the advantages of concrete and a steel structure can be given full play, namely, the compressive performance of the concrete and convenient construction of the steel structure, and it is ensured that the fabricated composite shear wall has good lateral stiffness; and compared with existing double-layer steel plate composite shear walls, the fabricated composite shear wall and the connection structure with the steel beams and the floors thereof can save more than 50% of the amount of steel, and reduce the amount of concrete pouring in the construction site and the amount of framework construction in the construction site, so that the construction of the shear wall is speeded up and the use of workers is reduced. The connection structure of the shear wall and the steel beams realizes the connection betweenthe steel beams and the fabricated composite shear wall by using joint members, and the occupied space of the connection structures can be saved.

Description

technical field [0001] The invention relates to a prefabricated combined shear wall and its connection structure with steel beams and floor slabs, which belongs to the field of prefabricated structural systems of building structures and can be widely used in civil buildings such as high-rise residences, apartments, office buildings and hotels. Background technique [0002] Steel structure construction enterprises are the inevitable result of construction industrialization and industrialization. [0003] At present, the prefabricated high-rise residential structural systems commonly used in the construction industry include cast-in-place reinforced concrete shear walls, prefabricated reinforced concrete shear walls, and double-layer steel plate composite shear walls. The former two require on-site formwork and concrete casting; the formwork needs to be removed after the concrete reaches the design strength, and the construction period is long; there is a lot of dust on site, ...

AI Technical Summary

Problems solved by technology

The former two require on-site formwork and concrete casting; the formwork needs to be removed after the concrete reaches the design strength, and the construction period is long; there is a lot of dust on site, and the water and electricity consumption is large, which is not in line with the general direction of green buildings promoted by the country.

Moreover, the weight of the prefabricated concrete shear wall is heavy, and it is difficult to transport and install; the steel consumption of the double-layer steel plate composite shear wall is large, the amount of welding on site is large, and the cost is high
