Embodiment Construction
[0017] Steel frame-steel tube fiber reinforced concrete cross-section composite column: it is composed of steel frame, steel pipe, steel skeleton and fiber concrete, the steel frame is welded by steel plate; The bones are on the limbs of the cross-shaped columns, the steel pipes are in the core of the cross-shaped columns, and the concrete is fiber-reinforced concrete. The upper limb of the cross-shaped column refers to the center of the rectangular part, and the steel ribs are arranged in a T shape. The core of the cruciform column refers to the center of the intersection of the limbs of the cruciform column. The specific process is as follows:
[0018] 1. Weld the steel plate into a steel frame according to the regulations;
[0019] 2. Fix the steel frame and steel pipe by welding or bolting, and keep it vertical or at a certain angle;
[0020] 3. Binding steel skeleton;
[0021] 4. Support formwork on the outside of the steel skeleton;
[0022] 5. Fully mix a certain p...
