双面叠合剪力墙生产的技术质量控制要点

KEY TECHNICAL CONTROL POINTS IN DOUBLE-SIDE PRECAST CONCRETE SUPERPOSED SHEAR WALL PRODUCTION

双面叠合剪力墙是将两块先后预制的混凝土薄板通过桥架钢筋连接,形成内部空腔的结构。由于双面叠合剪力墙操作难度较大,易发生叠合压入困难,两块预制板错位,钢筋露筋厚度偏厚,门窗洞处开裂等质量问题,针对这些技术问题,需采取控制措施加以解决。

Double-side precast concrete superposed shear wall is a structure using bridge steel to connect two pieces of precast concrete plate into a cavity structure.There are many difficulties in double-side precast concrete superposed shear wall construction,such as difficulty in superposing and pressing,dislocation of two pieces of precast slab,exposed steel and excessive thickness,crack at door and window openings,etc.Control measures shall be adopted to solve these technical problems.
