Assembly integral shear wall outer wall steel plate water stop, vertical steel bar same-strength and channel steel positioning connection
The invention belongs to the field of fabricated reinforced concrete building structures. The problems that in an existing assembly mode of shear wall PC components, vertical steel bars are difficult to connect, water leaks at joints and the bearing capacity of the section is not easy to guarantee, pre-embedded accessories are difficult to position and align in the prefabrication and assembly stage, the PC components cannot quickly stand by themselves, a large number of temporary supports are needed, and a working face is affected are solved. Through welding between the waterstop connecting steel plates and between the positioning connecting channel steel and the square steel pipe, equal-strength connecting anchoring of the vertical steel bars is achieved, and rapid self-standing of the shear wall PC component is achieved; the steel plate water-stop belt function is achieved through welding of water-stop connecting steel plates and post-pouring of micro-expansion concrete, the common quality problem of water leakage at the joint is solved, and the bearing capacity of the section at the joint is guaranteed; the PC component is precisely positioned, assembled and mounted through self-weight sliding guide by pre-embedded cut limb positioning connection channel steel and square steel pipes; the one-to-one accurate positioning of the connecting fittings at the joints is realized through factory prefabrication time sequence arrangement of the upper and lower PC components and the embedding process requirements of the embedded parts.
该发明创造属于装配式钢筋混凝土建筑结构领域，针对剪力墙PC构件现有装配方式中竖向钢筋连接困难、接缝处渗漏水及截面承载力不易保证、预制与装配阶段预埋配件定位与对位困难、PC构件不能快速自立需要大量临时支撑影响工作面发明创造。通过止水连接钢板间、定位连接槽钢与方钢管间焊接，实现竖向钢筋等强度连接锚固，实现剪力墙PC构件快速自立；通过止水连接钢板间焊接与后浇微膨胀混凝土实现钢板止水带功能，解决接缝处渗漏水质量通病、保障接缝处截面承载力；通过预埋切肢定位连接槽钢、方钢管实现PC构件自重滑动引导精确定位装配安装；通过上、下部PC构件工厂预制时序安排及预埋件埋设工艺要求实现接缝处连接配件一对一精确定位。
