JIN LINGLING / ZHANG LIMEI / LIU YUHONG

The invention discloses a movable formwork installation construction method for a bridge guardrail, and relates to the technical field of bridge construction. The movable formwork installation construction method for the bridge guardrail comprises the following specific operation steps that S1, an outer formwork is fixed according to the size of the guardrail, connecting pieces are arranged on the left side and the right side of each outer formwork, a cylinder is arranged in the middle of each connecting piece, a transverse pull rod is arranged on each connecting piece, and one side of each transverse pull rod fixedly penetrates through the corresponding connecting piece; and a convex groove is arranged at the lower end of the outer formwork; and S2, before hoisting, a magnet pendant is installed at a lower opening of the outer formwork. According to the movable formwork installation construction method, a U-shaped magnet pendant is arranged at the lower end of the formwork on the outer side of a guardrail, and the weight is obtained through calculation; the upper side of the formwork is provided with a traction rod inserted into the inner formwork, assembly of the formwork is achieved, the inner formwork is supported on the surface of the bridge through the inclined rods and the inner side of the formwork, and the protective layer cushion blocks of the steel bars play a role in protection.

本发明公开了一种桥梁护栏可移动式的模板安装施工方法，涉及桥梁施工技术领域。该桥梁护栏可移动式的模板安装施工方法，具体操作如下：S1、根据护栏的尺寸定作外模板，外模板上每块左右各设置连接件，连接件为中间带有一个圆柱，在连接件上设置横拉杆，横拉杆一侧固定穿在连接件上，同时在外模板的下端设置一凸形槽，S2、吊装前，将磁石坠安装在外模板的下口。该桥梁护栏可移动式的模板安装施工方法，主要通过在护栏外侧模板的下端设置一U型磁铁挂坠，重量通过计算获得；模板的上侧采用穿插入内模板的牵拉杆，实现模板的组装，内模板通过斜杆支撑在桥梁的表面，模板的内侧，钢筋的保护层垫块起到保护作用。
