Quality control method for basement wall column joint concrete pouring of different strength grades
The invention relates to a quality control method for basement wall column joint concrete pouring of different strength grades. The quality control method comprises the following steps that 1, a special instruction book is formulated, and submitting is carried out on site; 2, high-strength-grade concrete is separated from low-strength-grade concrete by adopting a simple closing-in net, specifically, a quick and easy closing-in net is selected, cutting is carried out according to the size of a shear wall, reinforcing steel bars are used as vertical ridges, the reinforcing steel bars with the spacing of 300mm are used as transverse ridges, shear wall steel bars are bound, shear wall horizontal steel bars penetrate through quick and easy closing-in net mesh grid holes, wall column formworks are installed, and the two side ends of the quick and easy closing-in net are fixed to the wall formworks and the column formwork through nails; and 3, the high-strength-grade concrete and the low-strength-grade concrete is poured synchronously. According to the quality control method for basement wall column joint concrete pouring of different strength grades, even if the concrete grade difference at the wall column joint is two strength grades, it can be guaranteed that no cold joint or crack exists at the wall column joint, and the concrete strength meets the design requirement.
本发明涉及一种地下室墙柱节点不同强度等级砼浇筑的质量控制方法，步骤一：制定专项指导书，现场进行交底；步骤二：采用简易收口网对高低强度等级砼分隔：选择快易收口网；根据剪力墙尺寸进行切割；用钢筋作为竖楞；钢筋间距300mm作为横楞；绑扎剪力墙钢筋，剪力墙水平钢筋穿过快易收口网网眼格孔；安装墙柱模板，采用钉子将快易收口网两侧端头固定在墙模和柱模上；步骤三：高低强度等级砼同步浇筑；本发明确保即使墙柱节点处混凝土等级相差2个强度等级的情况下，也能保证墙柱节点处无冷缝、无裂缝、混凝土强度满足设计要求。
