The main purpose of the building formwork is to form and maintain the new poured concrete to a certain strength to withstand the temporary structure of its own weight and to remove the model plate. The templating system of the reinforced concrete structure consists of two parts, one is a formwork that forms the shape and design dimensions of the concrete member; the other is a support system that ensures the shape, size and spatial position of the formwork.
The reason of the season is also the main point of consideration. The wood formwork in the building formwork has low thermal conductivity. When the concrete is constructed in winter, the wood formwork has certain heat preservation and protection effect.
