Fireproof steel-concrete composite shear wall
The invention discloses a fireproof steel-concrete composite shear wall. The fireproof steel-concrete composite shear wall comprises peripheral beams, peripheral columns and a fill plate. The fill plate comprises two opposite steel plates and concrete arranged between the steel plates. The fireproof steel-concrete composite shear wall is characterized in that hollow steel pipes are arranged between the steel plates, two ends of the hollow steel pipes are connected with the steel plates by welding, the steel plates are provided with circular grooves, the circular grooves are arranged in the contact surfaces of the steel plates and the hollow steel pipes, and the hollow steel pipes extend from the centers of the circular grooves. The fireproof steel-concrete composite shear wall further comprises end caps, and the end caps seal internal cavities of the hollow steel pipes. Compared with the prior art, the fireproof steel-concrete composite shear wall has the advantages that the structure is reasonable, rigidity and anti-shear capability can be adjusted by adjusting distribution density of the hollow steel pipes, the wall is high in fire resistance, intumescent fireproof sand can actively involve in fire extinguishment during fire disaster, the fireproof sand can be replaced by the aid of the end caps, and maintenance cost is reduced.
