Abstract

PROBLEM TO BE SOLVED: To improve the workability of a PC panel, its accuracy and the like by a method wherein tiles are arranged in a first form including longitudinal frames and lateral frames so as to place concrete in the first form in order to form PC panel and, after a demolding except the longitudinal frames is executed and then the PC panel is erected and linked to a second form and further concrete is placed in the second form in order to form a horizontal plate. SOLUTION: A first form including longitudinal frames 1 and lateral frames is framed on a plane so as to arrange tiles on the bottom surface part and side surface parts of the first form. Further, two rows of anchoring rebars 7 are disposed upright parallel to the lateral frames. After that, concrete is placed in the first form so as to form a PC panel 9. After that, the first from is demolded except the two longitudinal frames 1. Then, the PC panel 9 is erected vertically so as to link to a second from 11 framed separately. In this case, the anchoring rebars 7 are brought into a state being placed in the second form 11. After that, concrete is placed in the second form 11 so as to form an integral body, in which the horizontal PC panel and the vertical PC panel 9 meet at right angles, in order to form a PC panel having a T-shape section.

2. Description of the Related Art Generally, a PC board is used as a wall material, a floor material and the like, so that the PC board is formed into a flat plate shape. For example, a PC board used for a balcony is formed into a T-shaped cross section in which a vertical board serving as a handrail and a horizontal board serving as a floor intersect at a right angle.
In order to form a PC board having a T-shaped cross section, conventionally, for example, as shown in FIG. 9, a vertical plate form B for forming a vertical plate A serving as a handrail portion and a horizontal plate C serving as a floor portion are formed. A horizontal plate form D for molding is framed in a T-shaped section, and concrete is cast from above the vertical plate form B.

However, according to the conventional molding method described above, the workability of cast concrete is poor because the inlet E of the vertical plate form B is narrow, and compaction during concrete casting is difficult. Insufficient, so-called "junka" or "su" defects that occur when the periphery of the cement paste is poor are likely to occur. Tiles F are arranged on the vertical formwork surface in the vertical formwork B. However, it is difficult to fix the tiles to the formwork surface. Since the upper end surface of the formwork B is the concrete inlet E, there is a design restriction on the tile application at the upper end portion, that is, the specification in which the tile G exists on the upper end surface as shown in FIG. 10 cannot be obtained. Further, there is a problem that the cost is increased due to the complicated structure of the mold.
