Building plywood is a temporary structure, which is made according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the self-weight of the building plywood and the load acting on it. The purpose of the formwork project is to ensure the quality and construction safety of the concrete project, speed up the construction progress and reduce the project cost.
Combi Core Film Faced Plywood is a kind of construction plywood. The formwork is made of high-quality pine, eucalyptus and other boards. The surface is treated with phenolic resin impregnated paper with strong waterproofness. Named "Combi Core Film Faced Plywood". Mainly used in high-rise buildings, shear walls, vertical wall panels and dams, tunnels and overpasses, arch bridges and other bridges, beams and columns and other buildings formwork.
Generally, the commonly used ordinary plywood for concrete is poured as long as it can meet the rigidity (section size of the component and no deformation after pouring concrete) and flatness specified in the specification, and then the surface also needs plastering decoration, etc. It is mostly used for civil use Construction and certain requirements of industrial construction;
Combi Core Film Faced Plywood not only needs to meet the rigidity and flatness specified in the specification when pouring concrete components (to ensure that the cross-sectional size of the component and no deformation after pouring concrete) and flatness, it also needs to meet its smoothness, and the surface generally does not need to be plastered for decoration. , it is mostly used in industrial plant buildings and general industrial buildings;
According to the above, the main difference between ordinary plywood and Combi Core Film Faced Plywood is the process of formwork making and whether the surface after pouring concrete needs plastering, decoration and building use requirements, etc. There is no big difference in the use of materials.
