2. Description of the Related Art As is well known, as a floor material of a building,
2. Description of the Related Art A square wave forming plate called a so-called keystone plate has been developed and provided in which metal folded plates are joined together so that ridges and grooves are alternately continuous in the joining direction. Conventionally, this type of square wave forming plate is a metal folded plate material that is bent so that the ridges and grooves are alternately continuous in one direction.
Floors and walls of schools, factories, warehouses, temporary houses, etc., or
It is used as a base material for forming floors and walls of freezers and the like.

Conventionally, a square wave forming plate referred to as a keystone plate described above is constituted by a structure in which ridges and grooves are continuous over the entire surface, and thus is structurally excellent in mechanical strength and mechanical durability. I have.
On the other hand, in the case of constructing a floor of a building using this square wave forming plate, it is necessary to make a hole, provide an opening, or provide an escape for other structures in the square wave forming plate. There is. In this case, floor construction has conventionally been performed while performing secondary processing at the construction site. However, according to this conventional construction, for example, when an opening to be formed straddles a ridge and a concave groove, the opening forming operation is extremely difficult.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention
When constructing a floor or the like of a building by using a square wave forming plate such as a so-called keystone plate, the middle of the square wave forming plate in the direction of the ridge so that the secondary processing work in relation to other structures can be easily performed. An object of the present invention is to provide an intermediate closed angle wave forming plate having a novel structure in which a flat band portion formed by crushing a ridge is provided at a portion.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is, specifically, a metal square wave forming method in which a ridge and a groove are alternately continuous in one direction. In the plate, the ridge of the square wave forming plate is directed toward the floor side of the groove over a desired bandwidth along a direction intersecting the ridge at a longitudinal middle portion of the ridge. This constitutes an intermediate closed angle wave forming plate provided with a crushed flat band portion.

Further, in the present invention, the square wave forming plate constitutes an intermediate closed square wave forming plate made of a keystone plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an intermediate closed angle wave forming plate according to the present invention will be described in detail based on a specific embodiment shown in the drawings. FIG. 1 is a schematic perspective view showing a basic configuration example of an intermediate closed angle wave forming plate 1 according to the present invention. FIG. 2 is a diagram showing an intermediate closed angle wave forming plate having the configuration example shown in FIG. 2A is a schematic sectional view taken along the line 2A-2A in FIG. 1, and FIG. 2B is a schematic sectional view taken along the line 2B-2B in FIG. FIG. 2B is a schematic cross-sectional view taken along the line 2B-2B along the cross section.

First, a basic configuration of a square wave forming plate PL called a keystone plate will be described with reference to FIGS. The square wave forming plate PL is a so-called keystone plate.
mm to 1.2 mm, and is bent in one direction so that the ridges 2 and the grooves 3 are alternately continuous, and substantially the outer surface 2a of the ridges 2 Groove 3
And the outer surface 3a of the plate form a square wave forming plate having a dimension T = 25 mm in the plate pressure direction. Outer surface 2 of the ridge 2
a and the width dimension W of the outer surface 3a of the concave groove 3 are 40 mm, and the pitch dimension p between the ridges 2 is 90 mm.

The intermediate closed angle wave forming plate 1 according to the present invention comprises a flat band portion 4 provided on the above-described square wave forming plate PL. The flat band portion 4 is formed by the ridge portion 2 of the square wave forming plate PL.
Is formed by squashing toward the floor surface side 3b of the concave groove portion 3 over a desired bandwidth along a direction intersecting the convex ridge portion 2 at a longitudinally intermediate portion of the convex ridge portion 2. .

As shown in FIG. 2B, the flat band portion 4 of the intermediate closed angle wave forming plate 1 forms a flat folding rib 5 which is compressed in the plate pressure direction of the angle wave forming plate 1. In addition, the strength of the flat band portion 4 is ensured by the folding rib 5.

[0011] In the intermediate closed angle wave forming plate 1 according to the present invention, by providing the flat band portion 4 partially, the intermediate closed angle wave forming plate 1 can be attached to the body cloth or to another structure. In the case of installation and installation, a secondary operation for making a hole or providing an opening can be extremely easily performed. Further, the partial flat band portion 4 functions as a relief for securing a space for wiring and piping, and further forms a corner portion between the ceiling and the wall or a corner portion between the wall and the floor. In doing so, the bending process can be facilitated.

[0012]

The intermediate closed angle wave forming plate of the present invention having the above-mentioned structure has a simple structure, can be mass-produced on the factory side, and is extremely economically advantageous. In addition, it can be said that, when the floor or the wall of the building is constructed, it works extremely effectively in terms of shortening the construction period and improving workability.

Further, the intermediate closed angle wave forming plate according to the present invention is characterized in that the convex groove is formed at a middle portion in the longitudinal direction of the convex line along the direction crossing the convex line over a desired bandwidth. Similar to the provision of a flat band portion crushed toward the floor side of the slab, when this intermediate closed square wave forming plate is attached to the body fabric or to other structures, Dawn,
Secondary operations such as providing openings can be performed very easily, and the flat band functions as a clearance to secure space for wiring and piping. In forming a portion or a corner portion between a wall and a floor, it can be said that the present invention is extremely effective in that the bending process can be facilitated.
