Prefabricated assembling type composite plate type concrete double-connection shear wall with hidden supports
A prefabricated assembling type composite plate type concrete double-connection shear wall with hidden supports comprises cast-in-situ outer frame columns, middle columns, reinforced concrete composite walls and horizontal connecting beams, wherein the upper reinforced concrete composite wall and the lower reinforced concrete composite wall are vertically connected and provided with the hidden supports. The reinforced concrete composite walls with the hidden supports comprise prefabricated reinforced concrete wall shells, notches in the four corners, cavities, X-shaped steel diagonal bracings in the cavities, reinforcing ribs, notch steel bars and cost-in-situ concrete. The outer frame columns are core square steel pipe composite columns, stiffening ribs are arranged on the parts, at the joints, of square steel pipes, and the middle columns are provided with H-shaped structural steel. The upper wall and the lower wall are in indirect lap joint through the notch steel bars, connecting steel bars and the reinforcing ribs. The steel diagonal bracings are welded to the square steel pipes and the H-shaped structural steel by adding angle iron, shear resisting pin steel plates in connecting beams and the H-shaped structural steel are welded by adding angle iron, and thus the double-limb shear wall is formed. Compared with an existing prefabricated composite plate type concrete shear wall, the prefabricated assembling type composite plate type concrete double-connection shear wall is more reliable due to vertical connection and better in integrity, the bearing capability is greatly improved, multiple obvious earthquake resisting defensive lines are formed, and an ideal failure mode is achieved on the structure under the action of major earthquakes.
