BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dam formwork with a stonework pattern.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional dam form device comprises a plurality of single form panels 1 arranged in a longitudinal direction and a horizontal direction to form a large form form 2. Then, the lower part of the large frame 2 is pressed against the upper part of the already constructed concrete frame 4 and set, and concrete 5 is poured on the upper side of the concrete frame 4. The concrete dam is constructed while the formwork 2 is sequentially lifted and diverted from below to above.

[0003] In recent years, in order to make use of the natural scenery, it has been required to stop leaving the surface of the dam exposed to concrete and to apply various patterns.

In order to form a pattern on a vertical surface of a conventional concrete, a method of forming a concrete body while moving a formwork apparatus in a vertical direction has been disclosed in Japanese Patent Laid-Open No. Hei.
Japanese Patent Publication No. 214662 and Japanese Patent Publication No. 60-3592 have been proposed.

However, Japanese Patent Application Laid-Open No. Hei 1-214662 discloses a method of forming a patterned concrete body by extending a patterned sheet to a formwork device by extending it long downward, or separately forming a pattern for a joint. There is a trouble that it is necessary to prepare a sheet with a support and a support material,
Workability is also bad. Japanese Patent Publication No. 60-3592 discloses a concrete frame having corrugated ridges in a certain direction, and therefore cannot form a concrete surface with a complicated pattern.

Therefore, these prior arts cannot be used in the above-described dam formwork apparatus, and at present, the large formwork 2 is lifted up and the pattern forming plate is attached to the single formwork panel 1 each time it is converted. I was For this reason, workability was poor and construction efficiency was low.

[0007]

[Problem to be Solved by the Invention] Therefore, the present invention is capable of constructing a concrete dam without attaching a pattern forming plate when the large formwork in the dam formwork device is lifted up sequentially from below to convert it. Another object of the present invention is to provide a formwork device capable of forming a masonry pattern on the surface of a dam.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a dam form device with a masonry pattern according to the present invention has a long form and a short form formed by appropriately arranging a plurality of form panels in the vertical and horizontal directions. Frame, this large braided formwork is fixed on the back with thick ends,
When forming a concrete frame with this large formwork, in a dam formwork apparatus that is constructed while being lifted and diverted sequentially from the lower part to the upper part, each formwork panel of the large formwork is provided with a masonry pattern. The upper formwork panel and the lowermost formwork panel have the same masonry pattern.

[0009]

As described above, the formwork device for a dam with a masonry pattern of the present invention has a masonry pattern on each form panel of the large formwork, and the uppermost formwork panel and the lowermost formwork panel are used. Since the same masonry pattern is used, when constructing a concrete dam while diverting the large formwork from bottom to top and diverting it, the masonry at the upper end of the surface of the concrete frame formed first by concrete casting The large frame can be set on the pattern in close contact with the lowermost masonry-patterned formwork panel, so that workability is good and concrete can be immediately poured on the upper side of the concrete frame. Therefore, the concrete frame with the stonework pattern is sequentially extended upward while preventing the nodding leakage, and the dam with the stonework pattern can be efficiently constructed.
