Anti-cracking structure for joint of full-concrete outer wall under-window filling wall and shear wall and construction method thereof
The invention belongs to the technical field of concrete outer wall construction, and provides an anti-cracking structure for a joint of a full-concrete outer wall under-window filling wall and a shear wall and a construction method thereof in order to prevent the problem that cracks are generated at the positions such as the under-window wall due to concrete shrinkage. Anti-cracking steel bars and joint pulling plates are arranged in a concrete pouring layer at intervals, wherein the joint pulling plates comprise horizontal structure joint pulling plates and vertical structure joint pulling plates; the horizontal structure joint pulling plates are arranged between floors or beams of all layers and the under-window filling wall; and the vertical structure joint pulling plates are arrangedbetween the shear wall and the under-window filling wall; transverse anti-cracking steel bars are arranged at the joint of the shear wall and the under-window filling wall, and the transverse anti-cracking steel bars penetrate through the vertical structure joint pulling plates to be bound and overlapped with wall body steel bars of the shear wall and the under-window filling wall on the two sides. The anti-cracking structure is convenient to assemble and disassemble, construction joints are avoided, the hidden danger of water leakage of the structure is reduced, and the applicability is improved. The operation is convenient, the construction quality and effect are good, the change of the overall rigidity is avoided, the construction period is shortened, and the structural safety is guaranteed.
本发明属混凝土外墙施工技术领域，为防在窗下墙等部位因混凝土收缩产生裂缝的问题，提供一种全混凝土外墙窗下填充墙与剪力墙接缝处抗裂结构及其施工方法。在混凝土浇筑层内间隔设置抗裂钢筋以及拉缝板；所述拉缝板包括水平结构拉缝板和竖向结构拉缝板；水平结构拉缝板设置于各层的楼板或梁处与窗下填充墙之间；竖向结构拉缝板设置于剪力墙和窗下填充墙之间；剪力墙和窗下填充墙衔接部位设置横向抗裂钢筋，横向抗裂钢筋穿过竖向结构拉缝板与两侧的剪力墙和窗下填充墙的墙体钢筋绑扎搭接。安拆方便，避免施工缝的产生，降低结构渗漏水隐患，提高适用性。操作方便，施工质量和效果良好，避免整体刚度的改变，缩短施工工期，保证结构安全性。
