Vertical connecting steel bar on-site self-positioned superposed shear wall
The invention provides a vertical connecting steel bar on-site self-positioned superposed shear wall. Large-diameter vertical stressed steel bars and small-diameter unconnected vertical constructional steel bars are arranged on a wall body of the superposed shear wall and a prefabricated edge member area connected with a vertical post-pouring section, vertical holes penetrating through the laminated shear wall are formed in the corresponding positions of the large-diameter vertical stressed steel bars, the large-diameter vertical stressed steel bars of the lower-layer superposed shear wall are bent and extend into the bottom area of the vertical holes of the upper-layer superposed shear wall, or the tops of the large-diameter vertical stressed steel bars of the lower-layer superposed shear wall are provided with straight thread joints to be connected with or in welded connection with the vertical connecting steel bars, which are bent and extend into the bottom area of the vertical holes of the upper-layer superposed shear wall. After concrete is post-poured in the vertical holes from the tops of the vertical holes, lap joint connection of the large-diameter vertical stressed steel bars of the upper-layer superposed shear wall and the lower-layer superposed shear wall is achieved. According to the superposed shear wall, the problem of field positioning of post-insertion of additional vertical connecting steel bars into the vertical holes of the superposed shear wall can be solved, the field construction efficiency and precision are greatly improved, and the mounting speed of the superposed shear wall is increased.
一种竖向连接钢筋现场自定位的叠合剪力墙，在叠合剪力墙墙身及与竖向后浇段相连的预制边缘构件区域，设置大直径竖向受力钢筋和小直径不连接的竖向构造钢筋，在大直径竖向受力钢筋对应位置设置贯通叠合剪力墙的竖孔，下层叠合剪力墙大直径竖向受力钢筋弯折伸入上层叠合剪力墙的竖孔底部区域，或在下层叠合剪力墙大直径竖向受力钢筋顶部设置直螺纹接头连接或焊接连接竖向连接钢筋、弯折伸入上层叠合剪力墙的竖孔底部区域，从竖孔顶部浇筑竖孔内后浇混凝土后实现上、下层叠合剪力墙大直径竖向受力钢筋的搭接连接。本发明可避免叠合剪力墙竖孔内后插附加竖向连接钢筋的现场定位问题，大大提高现场施工效率和精度，提高叠合剪力墙安装速度。
