Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reusable fair-faced concrete wall formwork. Background Technique

[0002] The texture effect of wood grain is increasingly used in the facade effect of fair-faced concrete. Besides retaining the original and simple architectural style of traditional fair-faced concrete, it also adds natural elements. However, to achieve the wood grain effect, ordinary plywood cannot meet the requirements, and the surface in contact with concrete needs to have wood grain texture. The characteristics of wood grain board determine that the area of a single formwork cannot be too large. Therefore, the increase in the number of installed formworks also reduces work efficiency and affects the construction period.
