Vertical connection structure for precast concrete shear walls and construction method
The invention relates to the field of precast concrete structures, in particular to a vertical connection structure for precast concrete shear walls and a construction method. Steel bars in vertical distribution and steel bars in horizontal distribution are arranged on two sides of each vertical through hole of each precast porous shear wall which is a porous hollow wall. At a construction site, vertical connection between an upper precast porous shear wall and a lower precast porous shear wall is realized by arranging connection reinforcement cages and concreting or grouting mortar into floor cast-in-situ zones and vertical through holes of the precast porous shear walls. By the shear wall and the connection method, dead weight of a wall body is reduced, and cost is reduced as compared with that of a reinforcement sleeve grouting connection method. Compared with an existing core-pulled porous hoop-confined concrete reinforcement grouting anchor lap joint method or a metal corrugated tube porous reinforcement grouting anchor lap joint method, the vertical connection method has the advantages that hole quantity is reduced to prevent cracking of porous walls, and transport is facilitated due to the fact that the vertical steel bars in the precast walls do not protrude outside.
