Claims

[Claims for Utility Model Registration] (1) In a formwork in which a plurality of connecting frames are arranged inside a pair of left and right side plates, and both ends of each connecting frame are rotatably connected to both side plates, each of the above-mentioned The connecting frame is
At the bottom of the left and right side plates, there is an upward U-shaped lower horizontal strip whose lower ends are rotatably connected, and these lower horizontal strips are fixed near the upper ends of both sides, and the outer ends are connected to the tops of the left and right side frames. A formwork for creating slope protection works consisting of a pair of left and right horizontal bars that are rotatably connected to each other and fixed facing each other so that a slight opening is created at the inner ends. (2) The outward connecting parts formed at the top and bottom of the vertical bars fixed to the outside of both sides of the upward U-shaped lower horizontal reinforcement are rotatably connected to the above-mentioned both side plates, and placed at appropriate locations on the lower side of the lower horizontal reinforcement. A plurality of protrusions for positioning the lower main reinforcing bars are provided, and horizontal bars for receiving the upper main reinforcing bars are fixed on the inside near the upper end of both sides of the lower horizontal reinforcing bars, respectively.
The formwork for creating a slope protection work according to claim 1, wherein the inner end of each horizontal bar is bent upward to form a locking portion.
