The construction film faced plywood is composed of a panel and a support system. The panel is the part that makes the concrete shape; the support system is the structural part that stabilizes the position of the panel and bears the upper load. The quality of the formwork is related to the quality of the concrete project. The key is accurate size, firm assembly, tight joints, and convenient assembly and disassembly. The appropriate form of template should be selected according to the form and characteristics of the structure in order to achieve good technical and economic effects. The formwork and supporting system of large-scale and special projects must be calculated to verify the stiffness, strength, stability and ability of withstanding lateral pressure.
1. The film faced plywood is made of pine wood, and the thickness of the side slab of the ground beam is 20mm.
2. The bottom template of the main beam is made of pine wood, the thickness of the bottom template is 40mm, and the column template and floor template are made of machine-made film faced plywood with a thickness of 12mm.
3. The supporting system is made of cedar logs, the diameter of the small head is not less than 70mm, and the drawing connection is made of small square wood of 400×500mm, and the bottom supporting system is steel pipe support.
4. The film faced plywood and supporting system shall not be made of brittle, easily severely twisted and damp-deformed wood.
