PVC plastic formwork is a temporary structure, which is made according to the design requirements. it is a concrete structure, components are formed according to the prescribed position and geometric size, maintain its correct position, and bear the weight of the building formwork and the load acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up construction progress and reduce project cost.
The building formwork used in the construction of modern cast-in-place concrete structures is a temporary model structure to ensure that concrete structures are formed in accordance with the design requirements. It bears both horizontal and vertical loads during the construction of concrete structures.
The construction formwork structure for cast-in-situ concrete structure engineering is mainly composed of three parts: panel, supporting structure and connectors。 The slab is the bearing slab directly contacting the newly poured concrete; the supporting structure is the temporary structure supporting the slab, the concrete and the construction load, which ensures the solid combination of the building formwork structure, so as not to deform and destroy; the connecting part is to connect the slab and the supporting structure into an integral part。
