It is delivered to the site in this flat, folded state, and then formed into a rectangular tube shape for use. Similarly to the vertical beam formwork 1a, the horizontal beam formwork 1b should also be in a square tube shape as shown in Fig. 8 and Pt59, and in a flat folded state as shown in Fig. 10 and Fig. 7. Can be done. And each formwork 1a, la, lb. 1b, by joining the respective formworks 1a and 1b in a crosswise manner at their ends, as shown in FIG. 11, a formwork for constructing the slope frame can be obtained. [Example] Hereinafter, an example of the present invention will be explained with reference to the drawings. In the figure, A is a concrete slope, and the cross section is made up of eight beams A1 and cross beams A2, each having a rectangular cross section. la is a vertical beam formwork for constructing this M1 beam part A, and 1b is a horizontal beam formwork for constructing the WL beam part A2. Formwork 1a, 1a and cross beam formwork 1
b and 1b are combined in a lattice shape. As shown in Figs. 4 and 5, the vertical beam formwork 1a consists of a pair of side formwork plates 2.3 and a lower formwork formed using FT mesh plates to which thin reinforcing bars are tied vertically and horizontally. The plate 4 and the upper formwork 5 form a rectangular cylindrical shape as a whole, and separators 7 for connecting the formwork plates are arranged at required intervals in the length direction of the formwork 1. Moreover, this vertical beam formwork 1a has a structure that can be folded flat. That is, the separator 7 is
It is formed by connecting a plurality of horizontal stripes 8.8 and [112i9.9] in a cross-shaped pattern, and an engaging portion ]0.10 is provided at both ends of the horizontal strip 8. , an L-shaped mounting portion 11 is formed at its lower end, and a hook portion 12 is provided at its upper end. The side form plates 2.3 are rotatably connected to both ends of the sepapy tuff via engagement g10.10 of the transverse reinforcement 8.8 in a planar direction. Furthermore, one side end of the lower formwork plate 4 is coupled 13 to the lower end of the side formwork plate 2 of the negative force so as to be rotatable in the vertical plane direction, and the upper end of the side formwork plate 3 of the other force is connected to the lower end of the side formwork plate 2 of the other force. One end of the upper formwork plate 5 is coupled 14 so as to be rotatable in the direction of the joint surface. For example, as shown in FIG. 11, this rotatable connection 13.14 is made by holding reinforcing bars 15.15 at the side ends of the formwork plate 2.3.4.5 with S-shaped connecting fittings 16. The structure is as follows. As shown in FIGS. 6 and 7, the vertical beam formwork 1a is constructed by folding the upper formwork plate 5 so that it is aligned with the outer surface of the other side formwork plate 3 by rotation by the coupling part 14, Connect the frame plate 4 to the connecting part 13
*IF:! The frame 2 is folded so as to be aligned with the outer surface of the frame 2, and then the form plates 2.4 and 3.5 are rotated by the engaging portion 10.10 between the separator 7 and the form plate 2.3 to form a flat shape. It can be folded and transported to the site in that state. In addition, for the facility, the separator 7 is surrounded by each form plate 2, 3, 4, 5, as shown in Fig. engage and lock the parts. The lower formwork plate 4 is in contact with the mounting portion 11.11 of the longitudinal reinforcement 9.9. As shown in FIG. 8 and fiS9, the horizontal beam formwork 1b has the same structure as the vertical beam formwork 1a, but the difference is that the upper formwork board 6 is approximately half the width. That's true. Further, the above-mentioned separator can be applied as the separator 7, but as shown in the figure, one of the vertical stripes 9 may not be provided with the hook portion 12. The other foldable structure is the same as that of the vertical beam formwork 1a. Therefore, in the operating condition as shown in FIG.
An open hole 17 extending in the length direction is formed. -1= The vertical beam formwork 1a and the horizontal beam formwork 1b shown in Fig. 1,
