Intensive reinforcement in-hole lap joint prefabricated shear wall vertical connection structure and construction method
The invention discloses a prefabricated shear wall vertical connection structure of intensive reinforcement in-hole lap joint, in-hole lap joint connection is carried out by adopting large-diameter large-spacing intensive reinforcements under the condition that additional connecting reinforcements exist or do not exist, and by adopting large-diameter large-spacing vertical stressed reinforcements and large-diameter preformed holes, splicing construction and grouting are easy. The length of the vertical load-bearing steel bars extending out of the tops of the prefabricated shear walls is shortened, or the two ends of the vertical load-bearing steel bars are exposed in reserved hole channels in the two ends of the prefabricated shear walls and do not extend out of the prefabricated shear walls, and the vertical load-bearing steel bars in the upper-layer prefabricated shear wall and the lower-layer prefabricated shear wall are in lap joint through additional connecting steel bars. Collision possibly caused by outward extension of the reinforcing steel bars can be reduced or even avoided, and transportation and hoisting are convenient.
本发明公开了一种集约配筋孔内搭接的预制剪力墙竖向连接构造，采用大直径大间距集约配筋并在有或者没有附加连接钢筋的情况下进行孔内搭接连接，通过采用大直径大间距的竖向受力钢筋和大直径预留孔，易于拼装施工和灌浆。本发明缩短竖向受力钢筋外伸出预制剪力墙顶部的长度，或者使竖向受力钢筋两端均暴露于预制剪力墙两端的预留孔道中，不伸出预制剪力墙外，上、下层预制剪力墙内的竖向受力钢筋通过附加连接钢筋实现相互搭接，可降低甚至避免钢筋外伸可能引起的碰撞，方便运输和吊装。
