Ld. Wuhan Hubei 430064 China) Abstract:The problem of formwork expanding has always troubled the constructors.Moreover the fluidity and height of self-pacting concrete which is always used in steel plate concrete posite shear wall of super high-rise building is greater than that of the concrete of normal buildings which makes the problem more seriously.Based on the formwork engineering of steel plate concrete posite shear wall of Tianjin Gaoyin 117 Building two kinds of innovative technology of formwork reinforcement(reinforcement technology of splicing formwork-reinforcing by stud without welding reinforcement technology of typical large formwork--connector and high-s...
