る。2. Description of the Related Art Conventionally, a plywood veneer is generally used as a dam for a formwork. The plywood veneer has a considerable weight in the case of large dimensions, and is difficult to handle manually. In addition to the plywood veneer form, there is also a metal formwork made of steel or aluminum, which is heavier than the plywood veneer and is more difficult to handle manually.

右に筒状に組み合わせて設計断面のものとする。[0003] A plywood veneer or a metal formwork is used as a formwork for reinforced concrete or a steel-framed reinforced concrete square pillar by casting it into concrete, but four flat molds of any size are used. The frame panel is assembled in a tubular shape on the front, rear, left and right sides to obtain a design cross section.

よる型枠では任意の大きさに切断加工することは可能で
あるが、4枚の相互端部がコーナー部で突き合うように

なり、この部分でバレやすい型枠となる。Since the size of the formwork panel itself is determined in the above-mentioned metal formwork, in order to obtain a predetermined design cross-section, it becomes a special order product each time, and it is poor in versatility and cost. It will be high. On the other hand, a plywood veneer formwork can be cut to any size, but since the four pieces are assembled so that their mutual ends abut at the corner, the strength at this corner is weak. , And the mold is easy to be burred at this portion.

The plate is made of a translucent polymer compound such as polypropylene, polycarbonate, and vinyl chloride and has transparency, and a cut is made in one face plate of the hollow weir plate, and the other face plate facing the cut is bent. The weir plate is bent into a substantially L-shape, and the four substantially L-shaped weir plates are joined to form a tubular body having a rectangular cross section by abutting the ends thereof, or the gap between the face plates constituting the front and back surfaces is formed. The corrugated hollow corrugated board made of synthetic resin integrally connected by a plurality of reinforcing strips arranged in parallel in the longitudinal direction is made of a translucent polymer compound such as polypropylene, polycarbonate, and vinyl chloride, and has transparency. A cut is made in one face plate of the hollow weir plate, and the other face plate opposing the cut is bent to form a substantially U-shaped weir plate. The gist of the invention is that they are combined as a tubular body having a rectangular cross section.

ートの肉厚は1.0mm程度が適当である。As shown in FIG. 3, the hollow weir plate 1 is a corrugated cardboard panel made of a synthetic resin and includes a plurality of reinforcing strips 1c arranged in parallel in the longitudinal direction between face plates 1a and 1b constituting the front and back surfaces. They were integrally connected. This is made of a polymer compound such as polypropylene, polycarbonate, or vinyl chloride, and can be obtained by blow molding or extrusion molding. Incidentally, the thickness of the synthetic resin sheet forming the hollow weir plate 1 is suitably about 1.0 mm.

The inner space is partitioned in parallel by a reinforcing strip 1c connecting the a and 1b, and a large number of cavities are formed in one direction.
As shown in (1), a cut 2 in the longitudinal direction to reach this cavity is made in one face plate 1a in advance at a factory or a site.

る。At this time, the bent portion 4 of the face plate 1b serves as a hinge and can be easily bent, and when transported, the substantially weir-shaped bent dam plate 1 is flattened again as shown in FIG. You can carry it back in the shape. When transported in the form of a flat plate, a large number of sheets can be stacked and transported.

Two cuts 2 are provided at intervals, and the other face plate 1b opposed to the cut 2 is bent inside with a jig 3 made of square material inside to bend the entire dam plate 1 into a substantially U-shape. In this case, two substantially U-shaped weir plates are combined into a tubular body having a rectangular cross section by abutting the ends thereof.
