1. All kinds of steel required for template processing and manufacturing; The appearance quality and steel material must conform to the national standard of genuine steel. When necessary, the carbon content of steel should be strictly controlled.
2. In the process of steel formwork processing, the treatment of panel corners must be preferentially bent on the bending machine. If there is no requirement for fillet radius, 1.5 times of the steel plate thickness shall be taken as the bending radius value. [2]
structure
1. Steel formwork combination; The combined height of each section is 1200mm. The semicircle edge at the side of the pier shaft end is combined with the standard block, and the tray is disassembled and combined with the pier cap. The standard combined block is 1700 × 1202mm rib spacing 3500 × 4500 rib height (panel+rib height) 86mm.
2. Preparation of rib plate for steel formwork processing; The rib plate with special-shaped corner and surface must be welded on the clamping die for shaping. The template must be used for repeated correction. It is strictly prohibited to make it by hand.
3. The steel formwork shall be processed and the combined frame shall be processed into the sub master buckle shape.
4. Standard composite section of steel formwork; 8 split bolt holes shall be reserved in the processing of each section./5. The weld length of each welding position of the cross combination weld of the inner rib of the steel template shall be ≥ 70% of the rib plate width
