Wall construction process of treatment-free opposite-pull screw PVC (polyvinyl chloride) sleeve
The distance between the screws is calculated, then a formwork is built, plastic sleeves are reserved on the formwork according to the distance between the screws, the interior and the exterior of each plastic sleeve are evenly smeared with a release agent, PVC sleeves are installed, the length of each PVC sleeve is smaller than the width of the formwork, the two ends of each PVC sleeve are supported on the inner side of the formwork through rubber sleeve heads, and the plastic sleeves stretch into the rubber sleeve heads and are arranged on the PVC sleeves in a sleeving mode; a release agent is evenly smeared on the opposite-pull screw, then a PVC sleeve is inserted, installation of the opposite-pull screw is completed, and wall pouring is conducted; and in the later period of concrete solidification, the formwork, the opposite-pull screw, the plastic sleeve and the rubber sleeve head are removed, and a hole reserved in the rubber sleeve head is sealed through mortar. By the adoption of the method, the problem caused by overlong extending of the PVC sleeve is avoided, the construction period is shortened, and materials are saved; rubber sleeve heads are additionally arranged at the two ends of the PVC sleeve and supported on the inner side of the formwork, reserved holes are enlarged, later filling is facilitated, and the apparent quality of the shear wall is improved; and the opposite-pull screw rod and the plastic sleeve can be repeatedly used.
计算螺杆间距，然后搭建模板，在模板上按螺杆间距预留塑料套管，塑料套管内、外均匀涂抹脱模剂，安装PVC套管，PVC套管的长度小于模板宽度，PVC套管两端通过橡胶套头支护于模板内侧，塑料套管伸入橡胶套头并套于PVC套管上；对拉螺杆上均匀涂抹脱模剂，然后插入PVC套管，并完成对拉螺杆的安装，进行墙体浇筑；待混凝土凝固后期，拆除模板、对拉螺杆、塑料套管和橡胶套头，用砂浆将橡胶套头留下的孔洞封闭。采用本发明，避免了PVC套管外伸过长带来的问题，节省了工期，节约了材料；在PVC套管两端增加橡胶套头支护于模板内侧，扩大预留孔洞，方便后期填充，提高了剪力墙的表观质量；对拉螺杆、塑料套管可重复使用。
