The closing plate 18 can move up and down, closes the bottom surface of the outer frame 16 when concrete is poured into the outer frame 16, and descends after molding. A pallet 19 is placed on the upper surface of the closing plate 18. In this embodiment, in order to form three molded bodies by the outer frame 16, the two partition plates 16a, 16a divide the space into three spaces 17a, 17b, 17c. Each space 17
An insertion / removal opening 20 as a through hole is formed in each of the side walls a, 17b, and 17c. The insertion / removal opening 20 is opened downward, and the inner frame 22 is inserted along the pallet 19 on the closing plate 18 (see FIG. 2). The inner frame 22 is the U-shaped groove 1
It is formed in an inner shape of 0 and is in contact with the bottom surface of the pallet 19. Each inner frame 22 can be moved back and forth by a cylinder (not shown). The inner frame 22 is for securing a mold space having a U-shaped cross-section into the outer frame 16 in advance. In this state, a predetermined amount of hard concrete is put into the outer frame 16. The hardness of this concrete is 0
Use the one.

It should be noted that the pressure plate 24 and the outer frame 16 are vibrated when they are pressed and solidified. In FIG. 1, the state in which the pressing plate 24 is lowered is indicated by a one-dot chain line. The chamfer 1 of the bottom plate 12 of the U-shaped groove 10 is provided on both side edges of each pressing plate 24.
Chamfers 28, 28 are provided corresponding to 2a.
In addition, the pressing plates 24 are connected to each other by a connecting member 26 so that they operate simultaneously. After the concrete in the outer frame 16 is pressed and solidified, the inner frame 22 is inserted through the insertion / removal port 20 of the outer frame 16.
Pull out. Then, the pressing plate 24 is raised and the closing plate 18 is lowered (see FIG. 3). The three U-shaped grooves 10 are placed on the pallet 19 on the closed closing plate 18, and the U-shaped groove 10 is conveyed and cured together with the pallet 19.
