In the inside of the channel, a four-channel U-shaped light channel steel is used to arrange it in a square shape, and it is framed by welding (1
1) is buried approximately half, and a metal mesh (12) is entirely buried as a reinforcing aggregate, and openings (11a) located above and below a rectangular frame-shaped channel (11). Are arranged downward. The surface of the mold member (1) has a decorative part (1a) with a decorative finish, and a groove (1b) for sealing with a caulking agent or the like is formed on the side surface. (See FIG. 2). This groove (1b) prevents the concrete to be poured from leaking out of the overlapped portion of the formwork member (1) when stacking the formwork member (1) as a concrete formwork. It is for doing. Further, a large number of air vent holes (11b) are formed in the entire periphery of the channel member (11) protruding from the back surface of the mold member (1) (see FIG. 3). It should be noted that, as the form member (1), a "remaining form" filed by the present inventor on August 19, 1997 may be used. Further, as another form member (1), as shown in FIG. 4, a member in which a number of through holes (1c) are formed on the entire surface without applying a decorative finish to the surface may be used. At this time, the diameter of the through hole (1c) is in the range of 1 mm to 25 mm, and the shape of the through hole (1c) is not limited to a circle. If the diameter of the through hole (1c) is less than 1 mm, it is difficult to release air and check the degree of filling of the concrete. If the diameter of the hole is more than 25 mm, a large amount of concrete flows out during casting. Cause fear.

程を繰り返せば良い。Next, the step of stacking the form member (1) will be described. It is formed in a truss shape in advance with the connecting member (2) for stacking and the supporting frame member (3) (see FIG. 7A). At this time, the truss shape itself is in a state of being independent. First, the opening (11a) in the vertical position of the channel member (11) exposed on the back surface of the mold member (1) is hooked to the hooking member (22) [see FIG. 7 (b)]. Then, when the tightening screw (23) corresponding to the channel member (11) at the upper position is tightened, the hooking member (22) moves as shown by the arrow in the figure and comes into close contact with the end of the opening (11a). Then, it is fixed [see FIG. 7 (c)]. At this time, only the upper part of the form member (1) is fixed by the tightening screw (23), but the lower part of the form member (1) has the opening (11a) hooked to the hanging member (22). Therefore, the pressing force of the casting concrete does not come off. In this manner, the form member (1) is sequentially hooked on the hooking member (22), and the fastening screw (23) corresponding to the channel member (11) at the upper position is tightened and fixed, so that the step stacking is achieved. The work is completed [see FIG. 7 (d)]. In this case, the form member (1) is fixed at a predetermined distance from the inclined surface (4) and is installed in an independent state. After that, if the concrete is cast, the retaining wall is completed, but when the height of the retaining wall is high, the connecting member (2) for the stacking and the supporting frame member (3) are added to form the frame member. (1) may be stacked and the above steps may be repeated according to the height.

(1) with the opening (11a) positioned at the bottom facing downward and at least approximately half of the opening (11a) projecting from the back surface.
However, at a predetermined distance from the inclined surface (4) on the wall side, the formwork was assembled by successively stacking using the respective connecting tools (2) for stacking and the support frame member (3). Later, since the form member (1) is installed independently, the concrete
The construction of the retaining wall can be easily performed even by inexperienced part-time workers. As a result, there is no need to handle heavy objects as in the past, and it is not necessary to always secure qualified persons such as qualified persons for handling heavy objects, qualified persons for handling crane, and welding technicians. Is extremely easy, and the construction cost can be reduced and the construction period can be shortened. In addition, since approximately half of the cross section of the channel member (11) is exposed from the back surface of the mold member (1), the bonding property with the concrete to be cast is improved, and the strength is good. In addition, the opening (11a) of the channel member (11) can be easily inserted into the hooking member (22) of the connecting member (2) for stacking. Further, the opening (11a) having a U-shaped cross section of the channel member (11) is directed downward, so that the form member (1) is simply inserted into the connecting member for stacking (2) from above by one-touch operation. Attachment becomes possible, and as for the screw tightening work of the connecting tool for step stacking (2), the mold frame member (1) is fixed simply by turning the tightening screw (23) at a position where the hand can easily reach at least the upper part. Workability has been greatly improved.
In particular, even when the thickness of the concrete retaining wall is thin, the formwork of the formwork member (1) can be extremely easily assembled, and when the thickness of the concrete structure other than the retaining wall is small. Can also be applied.
