TECHNICAL FIELD The present invention relates to a concrete plate forming apparatus for forming a concrete plate for civil engineering laid on a slope or the like. Background art

As concrete boards, for example, those shown in Fig. 15 are known. This concrete plate 1 is formed integrally with ridges 2a, 2b in the center of the left and right sides of the rectangular plate, and has recesses 3a, 3a, 3b, 3b at each corner. At the same time, the protrusions (shafts) 4, 4 projecting from the recesses 3 a, 3 a of the right or left ridge 2 a are buried, and the other ridge is formed. Insertion holes 5, 5 through which the above-mentioned shaft protruding portions (shafts) 4, 4 are inserted are formed by burying pipes in the portion 2b. The surface 6 of the concrete board 1 shown in Fig. 15 is smooth and has no pattern. However, as shown in Fig. 16, the surface 6 has a decorative surface such as a stone wall. Some have various patterns on the surface 6, such as those with patterns.

When this concrete board 1 is used, for example, as shown in FIG. 17, a large number of concrete boards 1, 1,... Are prepared and these upper and lower flat boards are prepared. The side surfaces 7 are stacked and joined so that they are joined up and down, and the deformed side surfaces 8 with the ridges 2 are inserted through the projecting shafts 4 into the insertion holes 5. Combine them so that they are staggered left and right and continue in the left and right direction. In this way, a large number of concrete boards 1 are stacked up, down, left, and right according to the slope to construct a wall.

Conventionally, as a concrete plate molding apparatus for molding the concrete plate 1, for example, as shown in FIG. 18, the surface 6 of the concrete plate 1 is molded. A lower mold 12 integrally having a surface mold surface portion 11; and a side mold 13 for molding a side surface of the concrete plate 1. The side mold 13 is divided into several parts, each of which is fixed to the lower mold 12 around the surface mold surface 11 by a mounting bracket such as a bolt. The reason why the side molds 13 are divided is to facilitate removal from the mold. In particular, the part where the ridge 2 is molded is difficult to come off from the ridge 2 when removing the mold. The mold is divided into a direct mold 14 for molding the outer surface of the strip 2 and concave molds 15 and 15 for molding the side surfaces of the recesses 3a and 3b.

When molding the concrete plate 1, the divided side molds 13, direct molds 14, recessed molds 15 and the like are lowered by mounting brackets (not shown) such as bolts. Attach it to the mold 12, and in this state, put a reinforcing bar (not shown) embedded in the concrete plate 1 into the mold, and attach it to the erecting member 16 that extends between the side molds 13. The protruding members 9, 9, ... protruding from the back surface of the plate 1 are stopped by bolts and held. After that, the concrete is poured into the mold and cured for the required time. When removing the mold, the bolts and nuts are removed, the projecting members 9, 9, ... are separated from the erection member 16, the erection member 16 is detached from the side mold 13, and the bolt is further removed. Take the mounting brackets, etc., remove the side mold 13 from the lower mold 12, and then take out the molded concrete plate product.
