Abstract: A combined formwork includes a frame (8) composed of a shallow U-shaped profiled bar (1) and a panel (3) attached on one side surface of the frame (8). The shallow U-shaped profiled bar (1) forms a plate in the middle part, which is formed with a plurality of insertion through holes (2) in a line, and two flanges extending in the same direction on both sides of the plate viewing from the cross section. When the formwork is assembled, the side member of the frame (8) is aligned with that of another frame and the two side members are join together with a horizontal bolt (5) passing through the insertion through holes (2), which are aligned with each other, then a vertical bolt (6) is inserted to hold the horizontal bolt (5) in place, thus a plurality of formworks can be connected together each other.
