Description

[Detailed Description of the Invention] The present invention relates to a columnar material constituting a hollow column used, for example, as a shaft.

For example, in a prefabricated building, when constructing a wall by arranging multiple panels side by side, grooves are provided along both sides of the panels, and small grooves are fitted into the grooves facing each other in adjacent panels. This allows the panels to be connected together.

If the required strength can be ensured, it is better to form this kind of rod into a hollow column rather than a simple rod, and use the hollow part to insert electrical, telephone, or other wiring or piping.

For this reason, hollow columns have conventionally been used as hazes and piers, but since they are not integrally molded, they take up space in the factory for storage and are easily damaged during transportation.

There are also products that are shipped disassembled and then molded on site.
It requires the use of a large amount of adhesive, is time-consuming, and requires skill to develop an accurate method.

The present invention was developed based on the above circumstances, and its purpose is to provide a column-shaped material that has a very simple shape and that allows hollow columns to be formed easily and accurately on site. That is.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a columnar material, which is composed of sheets 1 to 1 made of, for example, vinyl sheets of appropriate thickness, and plate material 2 made of, for example, veneer plywood.

The plate material 2 is firmly overlapped and integrated with one surface of the sheet material 1 by welding or adhesive means.

Furthermore, the plate material 2 has a V-shaped groove 3 along the longitudinal direction.
are provided at the same distance from each other, and are cut out to form half V-shaped grooves on both side edges.

In other words, the plate material 2 is notched so that both edges along the longitudinal direction are inclined, and has a trapezoidal cross section.
By arranging four pieces, a V-shaped groove 3 is formed with each other's side edges.

On the other hand, the sheet material 1 has a plate body 2 only on one side along the longitudinal direction.
The molding fixing piece 1a is formed by protruding from the molding fixing piece 1a.

Thus, the columnar material constructed in this manner becomes a hollow column H as shown in FIG.

That is, the strip plate 4a on the side from which the molding and fixing piece 1a protrudes is lightly fixed horizontally as it is, and the adjacent strip plate 4b is erected vertically.

Then, the V-shaped groove 3 disappears and the inclined side edges join together.

The strip plate 4C adjacent to the standing strip plate 4b is directed horizontally, and the remaining strip plate 4d is directed downward.

Then, the inclined side edges of all the V-shaped grooves 3 come into close contact with each other, and both side edges along the longitudinal direction of the plate body 2 also come into close contact, so that a hollow column H is substantially formed.

Note that if this continues, if the biasing force is removed, the shape will collapse and return to the original flat plate shape.

Therefore, the hollow column H is completed by bending the forming and fixing pieces 1a of the sheet material 1 inward and overlapping them, and fixing this portion by means such as stapling.

After all, it is manufactured and stored at the factory in the form of a flat plate as shown in Figure 1, shipped as is, and then bent and formed on site.

The effort required at the site is only to bend the plate material 2 together with the sheet material 1 and to fix the forming fixing piece 1a.

As shown in FIG. 3, by fitting the hollow columns H into the grooves m and m provided on the opposing side edges of the panels p and It is possible to connect electrical and other wiring or piping through the hollow part.

In the above embodiments, the hollow pillar H is used as a stopper, but it is not limited to this, and can be used, for example, as a decorative pillar or the like.

As explained above, according to the present invention, the sheet material is integrally provided with a plate material provided with V-shaped grooves at a predetermined interval from each other along the longitudinal direction, and the sheet material is molded and fixed from one side edge of the plate material. Since the pieces are provided protrudingly, a hollow column can be formed by bending the plate material together with the sheet material along the V-shaped groove and overlapping the forming and fixing pieces.

Therefore, it can be stored and transported in a flat form, and it is easy to organize without taking up much space.

In addition, it can be made into a hollow column very easily, and it has various practical effects such as being easy to work with and having good workability.
