Hoisting construction of steel structure workshop in a city programme
Because the cushion cap foundation of the 5th and 6th lines of Axis G, the 5th and 6th lines of Axis F, and the 4th and 5th lines of Axis E cannot be constructed for the time being, the foundation of the electric furnace needs to be excavated immediately. In order to ensure the water outflow of the electric furnace across the roof on April 30, the hoisting sequence in the original construction organization design cannot be carried out. After careful study, we first hoisted nine steel columns and inter column supports, brackets, roof trusses, skylights, purlins and roof beams of Line G, Line 2, 3 and 4, Line F, Line 1, 2 and 3, and Line E, and then hoisted 10 steel columns and inter column supports, brackets, roof trusses, skylights, purlins and roof beams of Line G, Line 5, 6 and 7, Line F, Line 4, 5, 6 and 7, and Line E, respectively.
