2. Description of the Related Art Conventionally, when a PC board used for a wall board or the like is manufactured, when a pattern is formed on the PC board, first, a side surface and an opening of the PC board are placed at predetermined positions on a horizontal surface plate. After that, a peripheral formwork and an opening formwork are defined, and then a pattern-shaped rubber mat is laid on the surface plate surface in the peripheral formwork, and concrete is then poured and cured. As a result, a pattern was formed on the lower surface of the PC board.

[0003]

However, in such a conventional method of manufacturing a PC board with a pattern, it is necessary to cut the rubber mat each time and process it into an appropriate size depending on the size and position of the opening. Therefore, there is a problem that a lot of labor is required for the work and that a breakage portion is generated and a pattern missing portion is likely to occur. In addition, since the rubber mat is laid on the surface plate surface, the rubber mat cannot be removed until the concrete is removed from the mold, so the number of diversions of the rubber mat is reduced and productivity is poor, and the rubber mat deteriorates. Since it is easy to perform, there is a problem that the repeated use is limited and the manufacturing cost increases as a whole.

The present invention is a conventional PC with such a pattern.
It was designed to effectively solve the problems of plate manufacturing.It has excellent versatility without being restricted by the size and position of the opening, and easily forms a pattern on the surface of the cured member without missing parts. It is an object of the present invention to provide a pattern formwork which can be used at the same time as the number of diversions can be increased and is excellent in productivity, and a method for manufacturing a patterned PC board using the same.

It will be possible. At this time, in the invention according to claim 2, since the concavo-convex portion is also formed on the lower surface of the joint bar form, the concavo-convex corresponding to the interval of the joint bar form is formed on the surface of the hardening member. In addition to the pattern, a concave-convex pattern corresponding to the concave-convex part on the lower surface of the joint bar form can be formed in the concave part of the pattern, and thus, for example, a small stone masonry on the surface of the hardening member. A pattern or the like can be easily formed.

Further, according to the above-mentioned pattern form and the method for manufacturing a patterned PC board according to any one of claims 3 to 8, the pattern form is installed between the upper parts of the side form. Together with the joint bar formwork of the pattern formwork, since the width dimension is gradually reduced from the upper surface to the lower surface, it is formed in an inverted trapezoid, so that the hardened member such as cast concrete is about to solidify, It is possible to lift the pattern formwork vertically and remove it from the formwork. For this reason, compared to the case where a conventional rubber mat is used, the number of times the pattern formwork is diverted can be significantly increased to improve productivity, and the pattern formwork itself is installed between the upper parts of the side formwork. As a result, it is less likely to be damaged, and therefore it can be used many times and is economical.

Further, as in the invention according to claim 5 or 6, a color or bone is formed by using a hardening member, such as mortar, different from the concrete, on the surface portion of the concrete in which the joint bar formwork is embedded. By appropriately selecting the type of material, it is possible to give various changes to the pattern portion on the surface. In addition, as in the invention described in claim 7, even when the opening is formed in the PC board by the opening form arranged in the peripheral form, the pattern form straddles the opening form. It can be installed between the peripheral molds, and without being restricted by the size or position of the opening, it is possible to easily form a pattern over the entire desired area without missing parts, and to open one pattern mold. It can be diverted to the manufacture of PC boards of various shapes having different positions and sizes.

Further, in this case, when the pattern formwork is placed between the upper surfaces of the side surface formwork, the joint bar formwork spaces are formed on the upper surface of the side surface formwork as in the invention of claim 8. It is preferable to dispose a small weir plate that closes the gap, because it is possible to reliably prevent the concrete from flowing out from the gap between the joint rod forms when pouring concrete or the like.
