Double-steel-plate concrete composite shear wall for locking piece assembly stiffening

Abstract

The invention relates to a double-steel-plate concrete composite shear wall for locking piece assembly stiffening. The double-steel-plate concrete composite shear wall is characterized by comprising a wall body part and an edge part; the wall body part comprises a front plate component and a rear plate component which are arranged at intervals, a plurality of transverse connecting pieces distributed in an array mode are fixedly arranged on the inner side face of the front plate component, locking pieces in one-to-one correspondence with the transverse connecting pieces are arranged on the rear plate component, and the locking pieces are connected with the rear ends of the transverse connecting pieces in an assembling and disassembling mode; the edge parts are arranged on the left side and the right side of the wall body part respectively. The invention aims to provide a double-steel-plate concrete composite shear wall for locking piece assembly stiffening. The shear wall has the advantages that the two steel plates are assembled and connected through mechanical buckling of the studs (L-shaped plates) and the locking pieces to form the shear wall with the two steel plates pulled, pressed, restrained and fixed, and the problem of plate explosion during pouring and tamping of concrete is effectively solved; and automatic processing of factories can be realized, the labor intensity of workers is reduced, and the labor efficiency and productivity of the workers are improved.

Description

technical field [0001] The invention relates to structural design, factory manufacture and on-site construction of an industrialized steel structure building (fabricated steel structure building), that is, assembly construction, specifically a double-steel plate concrete composite shear wall with locks assembled and stiffened. Background technique [0002] In steel structures, especially residential steel structure buildings, steel plate composite shear walls are more likely to be accepted by the majority of residents than steel frame and frame support structures because they have fewer exposed columns and beams indoors, and are more widely used in high-rise residential buildings , in the JGJ380-2015 "Technical Regulations for Steel Plate Shear Walls", the recommended connection structure between the outer steel plate and the inner filling concrete of the steel plate composite shear wall adopts studs, T-shaped stiffeners, slabs or opposite The four connection methods of pull...

Problems solved by technology

There is a problem in these two steel plate combined shear walls: when concrete is poured into the steel plate wall during construction, the pressure on the side wall of the steel plate will make the steel plate buckle and deform; The lateral pressure generated by the 12-meter liquid concrete and the additional pressure caused by the vibration of the vibrator vibrating the dense concrete, this pressure value is very large, and the board often bursts

However, the amount of welding for each wall is very large. The production method determines that there are two vertical full-length welds every certain width. The more welds, the more factors will cause defects, and the larger the amount of processing and welding, the corresponding carbon emissions will be larger. , when pouring concrete, each closed cavity must be poured and compacted independently, and the construction is complicated
