Construction method for cable-stayed side formwork
The invention provides a construction method for cable-stayed side formworks. The construction method comprises the steps that anchoring steel bars are pre-buried in poured concrete; the side face formworks are hoisted in place through the formwork hoisting points; mounting a horizontal pull rod and a steel cone on the side template; pull rod connecting pieces are installed at the positions, protruding out of the steel cone, of the horizontal pull rods, the pull rod connecting pieces are divided into first sections and second sections which intersect, the first sections are parallel to the horizontal pull rods and fixed to the horizontal pull rods, and the second sections are parallel to the anchoring steel bars; and the two ends of the overall linear inclined pull rod are welded to the anchoring steel bars and the second section correspondingly. According to the inclined pull rod, a traditional bent inclined pull rod is changed into the overall linear inclined pull rod, so that a stress system is changed, displacement of the side formwork is reduced, and the size precision of a formed concrete structure is improved.
本申请提供了一种侧面模板斜拉的施工方法，该施工方法包括：将锚固钢筋预埋在已浇筑的混凝土中；利用模板吊点对侧面模板进行吊装就位；将水平拉杆和钢制锥体安装在侧面模板上；在水平拉杆凸出钢制锥体的位置处安装拉杆连接件，拉杆连接件划分为相交的第一区段和第二区段，第一区段平行于水平拉杆且固定在水平拉杆上，第二区段平行于锚固钢筋；将整体直线型的斜向拉杆的两端分别与锚固钢筋和第二区段进行焊接。本申请通过将传统的弯折型的斜向拉杆变成了整体直线型的斜向拉杆，使得受力系统发生改变，从而减少了侧面模板移位，提高了成型混凝土结构尺寸精度。
