Fabricated steel pipe supporting type outer-frame-free wall-attached construction protection system and method

The invention discloses a fabricated steel pipe supporting type outer-frame-free wall-attached construction protection system and a method. The fabricated steel pipe supporting type outer-frame-free wall-attached construction protection system comprises lower triangular truss bodies and an upper frame integral enclosure structure. Compared with the prior art, the building construction outer protection system is safe and reasonable in structure, excellent in overall performance, firm, simple and convenient to connect, high in assembly degree, green, environmentally friendly, capable of saving energy and low in construction cost. Bolt sleeves are adopted to stiffen local steel pipes in a joint area to reinforce local performance, steel pipe supporting pieces where upper bent clamping platesare welded are adopted to improve construction and installation efficiency, the steel pipe supporting pieces serve as a second defense line of the structure to improve the overall performance of the structure, and the fabrica
