Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to an assembled corrugated steel plate recycled concrete combined shear wall and a construction method thereof. Background Art

[0002] Urbanization and the demolition and reconstruction of existing buildings in cities generate an astonishing amount of construction waste, as well as waste concrete generated by the serious damage to a large number of buildings caused by major earthquakes. Construction waste and waste concrete contain a large amount of aggregate, which can be used as coarse aggregate to prepare recycled concrete. Recycling construction waste and waste concrete can reduce costs, save natural resources, ease the contradiction between supply and demand of concrete raw materials, and reduce the pollution of waste concrete to the environment. Therefore, the effective application of recycled concrete in engineering has become a major demand for the recycling of building materials and the resource utilization of construction waste.

[0003] As a commonly used lateral force resisting member in high-rise buildings, steel plate concrete shear wall has high bearing capacity and lateral stiffness, can effectively resist horizontal shear force, prevent shear failure of the structure, and has good seismic performance. The steel plates on both sides of the double steel plate concrete shear wall can not only constrain the internal filling concrete during the use stage to improve the concrete strength, but also serve as a template for concrete pouring during the construction stage, which is convenient for construction. In the prior art, the internal concrete deformation of the steel plate concrete composite shear wall during the stress process can easily cause the steel plate to bulge, which may cause damage to the welding parts and affect the use of the shear wall. In order to avoid out-of-plane buckling of the steel plate, thick steel plates must be used or a large number of stiffening ribs must be arranged on the thin steel plates. The use of corrugated steel plates can make the performance of thin steel plates close to that of thick steel plates by virtue of the out-of-plane stiffness of the corrugated steel plates themselves, significantly improving the working performance of the steel plate concrete composite shear wall. Summary of the invention

[0004] The object of the present invention is to provide an assembled corrugated steel plate recycled concrete combined shear wall and a construction method thereof, so as to avoid local buckling of the steel plate and facilitate construction.

[0005] The technical solution adopted by the present invention is: an assembled corrugated steel plate recycled concrete composite shear wall, comprising:

[0006] A frame column, comprising a cylindrical steel pipe and a concrete layer, wherein the first recycled concrete layer is arranged in the cylindrical steel pipe; and

[0007] The shear wall comprises two closed corrugated steel plates, two open corrugated steel plates and a second recycled concrete layer. The two closed corrugated steel plates and the two open corrugated steel plates are fixedly connected between adjacent frame columns. The two closed corrugated steel plates are respectively arranged on the outer sides of both ends of the two open corrugated steel plates. The second recycled concrete layer is arranged between the closed corrugated steel plates and the open corrugated steel plates and between the two open corrugated steel plates.

[0008] Beneficial effects: The assembled corrugated steel plate recycled concrete composite shear wall is composed of a closed corrugated steel plate and an open corrugated steel plate as a shear wall, and frame columns are arranged at both ends of the shear wall. The use of the closed corrugated steel plate is conducive to the bonding between the second recycled concrete layer and the open corrugated steel plate and the closed corrugated steel plate. The open corrugated steel plate can make up for the lack of rigidity of the closed corrugated steel plate and jointly constrain the second recycled concrete layer. The frame columns on the left and right sides of the shear wall have large rigidity and can provide sufficient constraints to the shear wall to avoid local buckling of the shear wall. The assembled corrugated steel plate recycled concrete composite shear wall can improve the applicability of concrete and facilitate construction.

[0009] Furthermore, the frame column also includes an H-shaped steel, and the H-shaped steel is arranged in the columnar steel tube.

[0010] Furthermore, bolts are provided on the inner side surface of the cylindrical steel pipe and the outer side surface of the open corrugated steel plate.

[0011] Furthermore, a plurality of grouting sleeves are arranged in the frame column and the shear wall.

[0012] Furthermore, part of the grouting sleeves are distributed in the frame column along the diagonal line, and the remaining grouting sleeves are arranged in the shear wall at intervals along the outer side of the open corrugated steel plate.

[0013] Furthermore, the grouting sleeve is higher than the top surfaces of the frame column and the shear wall.

[0014] Furthermore, the cross section of the cylindrical steel pipe is set to be rectangular.

[0015] A construction method for an assembled corrugated steel plate recycled concrete composite shear wall comprises the following steps:

[0016] S1. Frame column assembly: Place the H-shaped steel in the cylindrical steel pipe, and weld the studs at intervals to the inner side of the cylindrical steel pipe;

[0017] S2. Shear wall assembly: two open corrugated steel plates are fixedly connected between adjacent frame columns, studs are welded on the outer sides of the two open corrugated steel plates, and two closed corrugated steel plates are fixedly connected between adjacent frame columns, and the two closed corrugated steel plates are respectively located on the outer sides of the two open corrugated steel plates;

[0018] S3. Recycled concrete filling: Pour recycled concrete into the frame columns and shear walls, and pre-embed the grouting sleeves into the frame columns and shear walls. Connect the upper and lower sections of the assembled corrugated steel plate recycled concrete composite shear wall through the grouting sleeves. Repeat the construction after solidification until the overall construction of the assembled corrugated steel plate recycled concrete composite shear wall is completed.

[0019] Beneficial effect: In the construction method of the assembled corrugated steel plate recycled concrete composite shear wall, the shear wall adopts a combined structure of closed corrugated steel plates and open corrugated steel plates. The open corrugated steel plates can make up for the lack of rigidity of closed corrugated steel plates, and can improve the constraint on the second recycled concrete layer in the shear wall to avoid local buckling of the shear wall. Studs are welded on the inner side of the columnar steel pipe and the outer side of the open corrugated steel plate to improve the overall constraint force. The recycled concrete has high overall rigidity and is conducive to the reuse of resources. BRIEF DESCRIPTION OF THE DRAWINGS
