Anti-floating construction method for formwork of foundation pit of elevator shaft
The invention relates to an anti-floating construction method for an elevator shaft foundation pit formwork, and belongs to the field of building construction. According to the technical scheme, the anti-floating construction method comprises the following steps that S1, drilling is conducted on a bottom formwork of the foundation pit formwork; s2, a wall-penetrating screw rod penetrates through a bottom die hole of the template and then is firmly welded with the upper-layer and lower-layer steel bars of the bottom plate; s3, sleeving the upper ends of the tops of the side molds with the channel steel; s4, the square steel pipes are arranged on the channel steel at the tops of the formwork bottom die and the side dies; and S5, the steel pipes are arranged on the bottom square steel pipe and the top square steel pipe in the direction perpendicular to the square steel pipes and are firmly fixed through double-ring fixing buckles and lead screw nuts, a set of firm tie reinforcing system is formed, the formwork is prevented from floating upwards during concrete pouring, construction is easy, and the construction quality is improved.
本发明涉及一种电梯井基坑模板抗浮的施工方法，属于建筑施工领域，其技术方案包括以下步骤：S1、基坑模板底模钻孔；S2、穿墙丝杆穿过模板底模孔洞后与底板上层及下层钢筋焊接牢固；S3、槽型钢套在侧模顶部上端；S4、方形钢管布置在模板底模和侧模顶部槽型钢上；S5、钢管垂直方形钢管方向布置在底部和顶部方形钢管上，用双环固定卡扣和丝杆螺母固定牢固，构成一套牢固的拉结加固体系，防止浇筑混凝土时模板上浮，施工简单，提高施工质量。
