Fabricated structure edge protection construction method

CHEN XINGCHI / ZHANG YANG / LI SHENG

The invention relates to the technical field of protection, in particular to an assembly type structure edge protection construction method. Steel bars are welded into a plurality of cross-shaped supports, the cross-shaped supports are arranged at the adjacent edges of the structural floor slab at intervals and are in the same row with the steel columns on the adjacent edges, and the bottom ends of longitudinal bars of the cross-shaped supports are welded to the structural floor slab; the upper part of the longitudinal bar of the cross-shaped support is sleeved with a steel pipe; fasteners are installed on the steel pipes, transverse rods are installed on the fasteners, and the transverse rods are connected with the fasteners on the adjacent steel pipes or abut against the adjacent steel columns. And dismantling the lifeline and carrying out construction operation. The welded cross-shaped support serves as an anchor point, the steel pipe serves as a connecting piece, the cross rod serves as rigid edge protection, the safety production function is achieved, the construction period is guaranteed, meanwhile, use of materials and machines is reduced, finished product protection work is facilitated, after construction is completed, the cross rod and the steel pipe are detached, and the cross-shaped support is cut off along a finished surface, and the construction cost is reduced. Most materials can still be recycled.

本发明涉及防护技术领域，具体是一种装配式结构临边防护施工方法。使用钢筋焊接成若干个十字撑，若干个十字撑间隔布置在在结构楼板的临边处且与临边的钢柱同排，将十字撑的纵筋底端焊接在结构楼板上；在十字撑的纵筋上部套装有钢管；钢管上安装有扣件，扣件上安装有横杆，横杆与相邻钢管上的扣件相连或者与相邻的钢柱相抵；将生命线拆除并进行施工作业。通过焊接的十字撑作为锚点，钢管作为连接件，通过横杆作为刚性的临边防护，满足安全生产功能，而且在保证工期的同时，减少材料和机械的使用，有利于成品保护工作，施工完成后，将横杆和钢管拆卸，沿完成面将十字撑切除即可，大部分材料仍可周转使用。
