Since each floor is constructed in stages, it is inevitable to leave horizontal construction joints at the concrete structure floors. The usual method of supporting the facade formwork is: the lower concrete structure is completed before the upper concrete structure is constructed. When supporting the upper concrete structure formwork, the exterior wall and column formwork is hung down to the lower concrete structure and extends below the horizontal construction joint of the floor. Pressure is applied to the outside of the lower hanging formwork by means of reserved bolts, etc., so that the inner side of the formwork is close to the side of the construction joint of the lower concrete structure, and finally, the upper structure concrete is poured. The existing concrete structure horizontal construction joint formwork device cannot adjust the length of the construction joint and post-casting strip formwork tools, and is relatively poor in practicality when used for different buildings; although the formwork tools provided can be connected and fixed to the steel bars, they cannot meet the installation of steel bars of different thicknesses.
