the first step: according to designing requirement, carry out corrugated sheet steel (11) blanking, wave steel plate drawknot stirrup (22) is connected with corrugated sheet steel (11) medial surface, steel deck-plate drawknot stirrup (23) is connected with steel plate bar cover plate (12) medial surface, then steel plate bar cover plate (12) is covered fully the groove of corrugated sheet steel (11), and be connected firmly, wave steel plate drawknot stirrup (22) and steel deck-plate drawknot stirrup (23) are superimposed with each other to cross and form hollow and enclose frame, at last vertical reinforcement (24) insert port font is enclosed four jiaos and location of frame, formation is with the strip grid steel pipe wallboard (1) of welded reinforcement skeleton,
Second step: in the upper cavity that is formed by steel plate bar cover plate (12) covering sealing corrugated sheet steel (11) groove of strip grid steel pipe wallboard (1), perfusion self compacting high strength degree concrete, form pipe inner concrete (21), curing concrete, after waiting for that pipe inner concrete (21) knot is hard, form reinforced concrete post (2) in pipe;
The 3rd step: transportation is arrived the job site with the strip grid steel pipe wallboard (1) of reinforced concrete post (2) in pipe, lifting puts in place, strip grid steel pipe wallboard (1) left and right sides and edge steel column (3) be welding firmly, the firmly welding of strip grid steel pipe wallboard (1) both sides, up and down and edge girder steel (4) forms strip grid steel tube-concrete composite structure shear wall.
