Abstract
The invention discloses a method for mounting an overall steel protective shed cantilever frame. The method comprises the following steps: mounting and fixing I-steel by using a reinforced ring which is pre-buried on an outside beam of a main body structure floor and a lower-layer temporary outer scaffold cantilever frame, wherein the I-steel is fixed on the edge of cantilever shape steel by using the reinforced ring; welding channel steel as an inclined support rod by using a hydraulic adjustable support rod; connecting and fixing assembled hinging components at two ends of the inclined support rod; welding a short reinforced head with I-steel on the ground, laying steel plates on adjacent pieces of I-steel, welding a plurality of reinforcing steel bars on the surfaces of the steel plates so as to form reinforcing ribs, inserting an outer scaffold vertical rod into the short reinforced head to form an outer building protective frame, erecting horizontal long steel tubes and vertical short steel tubes to form a protective shed, inserting the vertical short steel tubes into the short reinforced head, laying a bamboo scaffold plate on the horizontal long steel tubes, and setting a protective rail outside the protecting shed. As a manufactured double-layer protective shed is lifted in place by using a tower crane, the method is safe, economic and rapid, no ground or solid foundation is needed as a support, and the bearing capacity of a cantilever steel beam can be greatly increased due to twice oblique-pulled unloading of high-strength steel wire ropes.
