Method for reinforcing formwork at corner of super-thick shear wall
The invention discloses a method for reinforcing formworks at the corners of a super-thick shear wall. The method comprises the following steps of pouring a foundation raft, then erecting wall body steel bars, then respectively erecting L-shaped formworks on the external corner side and the internal corner side of the shear wall, and finally, arranging vertical secondary keels and transverse main keels on the outer sides of the two formworks to reinforce the formworks. Vertical I-shaped steel is pre-buried in the foundation raft before the foundation raft is poured, the height of the I-shaped steel is consistent with that of the wall, a plurality of layers of opposite-pulling assemblies are evenly welded in the height direction of the I-shaped steel, each layer of opposite-pulling assembly comprises a plurality of opposite-pulling screws, each opposite-pulling screw is perpendicular to the corresponding edge of the formwork on the external corner side, one end of each opposite-pulling screw is fixedly connected with the I-shaped steel, the other end of each opposite-pulling screw sequentially penetrates through the formwork, the secondary keels and the main keels, and fasteners are sleeved on the opposite-pulling screws on the outer sides of the main keels. According to the reinforcing method, the construction difficulty can be reduced, the formworks at the corners of the super-thick shear wall can be effectively reinforced, formwork explosion and formwork expansion are avoided, and the structural quality of the wall can be improved.
本发明公开了一种超厚剪力墙转角处模板加固方法，浇筑基础筏板后绑架墙体钢筋，然后再在剪力墙阳角侧和阴角侧分别搭设L型模板，最后在两模板外侧设置竖向的次龙骨和横向的主龙骨以对模板进行加固，在浇筑基础筏板前在基础筏板里预埋竖向的工字钢，工字钢的高度与墙体高度一致，在工字钢的高度方向上均匀焊接若干层对拉组件，每层对拉组件包含复数根对拉螺杆且每根对拉螺杆与阳角侧模板对应边垂直，每根对拉螺杆一端与工字钢固定连接，另一端依次穿过模板、次龙骨和主龙骨并在主龙骨外侧的对拉螺杆上套设紧固件。该加固方法有利于降低施工难度，且能有效对超厚剪力墙转角处模板进行加固，避免爆模和胀模的发生，并且还能提高墙体的结构质量。
