Interim support frame of steel case roof beam installation

The utility model provides an interim braced system of steel box girder sections installation strides greatly, through the processing of truss -like standard segment, can solve current bearing structure exist set up loaded down with trivial details, the engineering time long and difficult nimble turnover not enough. An interim support frame of steel case roof beam installation, this support frameof includes concrete strip shape basis, lattice column and work platform, the lattice column sets up on concrete strip appears the basis, work platform sets up on the lattice column, and concrete strip shape basis is built -in foundation bolt upward, the last square steel plate that installs of rag bolt, the lattice column includes multisection steel pipe truss structure, connect through the flange dish between the multisection steel pipe truss structure, the steel pipe truss and the square steel plate welding of bottom, work platform includes at the I -steel of lattice column top horizontal -associate and lays the di
