Description

  The present invention relates to a building unit of a concrete structure and a building construction method thereof, and more particularly to a building unit of a concrete structure used for a foundation structure and a wall of a building and a building construction method thereof.

  Generally, a concrete structure such as a foundation structure or a wall of a building is constructed by installing a formwork at a construction site and placing concrete in a space formed between the formwork. Conventionally used wooden plywood formwork is dismantled, cleaned and reused when concrete hardens.

  In addition to such a wooden plywood formwork, in recent years, a steel formwork called a lath formwork has become widespread and has been used for building construction of concrete structures. This lath formwork is refilled as it is without being dismantled and reused even after concrete placement. For this reason, the plate-like portion of the mold body is formed in a metal mesh shape (mesh shape) to reduce the cost of the material. In addition, by forming in a mesh shape in this way, the weight of the entire formwork is reduced and the workability is improved, and excess water of concrete is leaked from between the meshes, so that high quality concrete Can be cured.

As one of the prior arts using such a lath mold, a lath mold method disclosed in Patent Document 1 and a lath mold frame plate have been proposed.
This lath formwork plate integrally forms a protruding column portion and a lath net portion having a substantially U-shaped cross section protruding outward, and a protruding end surface protruding outward of the protruding column portion. By fixing the horizontal end on the outer surface of the mold, and building the formwork, while taking advantage of the weight reduction and material cost reduction that are the advantages of the slats using the lath net, the rigidity when built as a formwork Strengthening and improving the construction method so that concrete can be placed on the slab at the same time as the beam and wall, improving workability.
Moreover, it is possible to leak the excess water of the concrete from the unused one of the openings for inserting the separator provided in the dam plate.

For example, the size of the finished product of the form panel 1 is about 300 to 7000 mm in length, 600 mm in width, and about 0.2 to 1.0 mm in thickness.

In this way, by bending the panel steel plate into a substantially square wave shape in cross section, a plurality of parallel strips 11 are arranged in parallel at a predetermined interval on the formwork panel 1 to reinforce the strength of the panel 1 itself. .
Further, by forming the cross section of the panel into an equilateral angular wave type, particularly excellent strength against the force from the front surface or the back surface side is exhibited.
Hereinafter, the direction in which the ridges 11 are formed is referred to as the “length direction” of the mold panel 1, and the direction perpendicular to the length direction of the mold panel 1 is referred to as the “width direction”.

As shown in the figure, the ridge 11 is composed of an upper surface 31 and two side surfaces 32 that are connected in the width direction of the upper surface 31.
The length in the width direction of the upper surface 31 and the length in the width direction (depth direction) of the side surface 32 are, for example, about 10 to 20 mm.
