Description

[Detailed explanation of the invention] <Technical field> This invention relates to a folding plate structure, and in more detail,
This invention relates to a folded structure suitable for roofs, ceilings, walls, protective walls, etc. of houses.

<Background and prior art> Conventionally, folded plates, which are formed by bending a metal plate or the like into a rectangular wave cross-sectional shape, have a strong structure and can be manufactured at low cost, so they have been used as roofing materials, ceiling materials, and wall materials for houses. It is also used as a construction material for protective fences, etc.

However, due to the structure in which the uneven surface of the folding plate is exposed, it lacks a sense of solidity and gives a poor appearance, which is undesirable in terms of appearance. Particularly, when used as a ceiling material for a general house, it is necessary to cover the surface of the folded plate with a decorative board, making the construction work very troublesome and expensive.

<Purpose> This invention was made in view of the above-mentioned problems, and the purpose is to provide a folded plate structure that has a good appearance and can facilitate ceiling construction.

<Structure> The folding plate structure of this invention to achieve the above object has a three-dimensional space on one or both sides of the folding plate body in which valleys and peaks are arranged alternately.
It is characterized by being closed with a band-shaped cover.

<Example> Hereinafter, an example of this invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the folded plate structure of this invention, in which a folded plate 1a having a cross-sectional square wave shape in which troughs 11 and peaks 12 are formed alternately is overlapped with its side ends. In this state, a plurality of plates are spliced together to form a folding plate main body 1a, and a three-dimensional space S formed inside the mountain portion 12 is closed with a band-shaped cover 2 made of metal or synthetic resin.

More specifically, the rising base of the mountain portion 12 has undercut-shaped fitting recesses 13a, 1.
3b is formed (see especially FIG. 2), and the cover 2 can be folded by fitting the fitting convex portions 23a, 23b formed at both ends of the cover 2 into the fitting concave portions 13a, 13b. It is adhered flush with the bottom surface of the valley portion 11 of the plate body 1a. Above cover 2
The fitting projections 23a and 23b of the cover 2
Both ends of the folding plate main body 1a are connected to the fitting recesses 13a, 1
3b, and is bent into a hook shape etc. that can be adapted to the folding plate main body 1a, while elastically bending the cover 2 by pressing.
It can be easily fitted by simply pushing it into place.

Further, as shown in FIG. 2, a linear bending groove 20 is formed along the longitudinal direction of the center of the cover 2. Therefore, with the bending groove 20 as a fulcrum, the cover 2
can be easily bent.

Note that the fitting projections 23a and 23b of the cover 2
In the case of the figure, is formed into a hook shape that is one step higher, and the distance l between the fitting projections 23a and 23b is set as follows.
It is set to be shorter than the width L of the legs at the base of the mountain part 12 (see Fig. 3), and when the cover 2 is attached to the folding plate main body 1a, there are many stripes extending in the longitudinal direction at both ends of the cover 2. Parallel grooves m can be formed (see FIG. 1). Therefore, by printing a woodgrain pattern or the like on the surface of the cover 2 and the folding plate, it is possible to easily construct a ceiling or side wall with a texture similar to that of plate joints.

In order to employ the folded plate structure with the above configuration as a ceiling structure of a house, etc., for example, the required number of folded plates are successively installed on a beam material A made of I-beam steel etc. by overlapping and splicing, and the consecutively installed folded plates are The main body 1a is fixed to the beam material A by appropriate means such as welding or fasteners. Then,
Fitting recesses 13a, 13 formed in the folding plate main body 1a
b, fitting projections 23 formed on both sides of the cover 2;
By fitting a and 23b, the folding plate main body 1
It is sufficient to close the three-dimensional space S of a (see Fig. 4).

At this time, since the linear bending groove 20 is formed along the longitudinal direction of the center of the cover 2, the cover 2 can be easily bent using the bending groove 20 as a fulcrum.
This makes it easy to attach the cover 2 to the folding plate main body 1a, which is very convenient. Particularly in this case, together with the linear parallel grooves m formed on both ends of the cover 2, a striped pattern appears on the surface of the folded plate, giving it a unique texture and appearance as a home ceiling or wall material. This results in a folded plate structure with a better appearance (see especially FIG. 4).

Ceiling materials for homes, etc. formed by the above-described construction are extremely easy to construct and have a good appearance.

The fitting protrusions 23a and 23b formed on the folding plate main body 1a and the cover 2 may be formed in various fitting forms other than those shown, such as dovetail fitting.

The shape of the bent groove 20 can be various shapes such as a diamond-shaped cross section, a V-shape, an Ω-shape, and a concave shape (see FIG. 5).

Further, the fitting uneven portions 23a and 23b formed on the folding plate main body 1a and the cover 2 may be formed not only in a series but also partially. In addition to the structure, conventional connecting means can be adopted, such as connecting with a flap or a hanger in which the side ends of the folded plates are overlapped and tightened.

Furthermore, it is also possible to apply the cover 2 to the three-dimensional space S formed between the adjacent peaks 12, 12, and to close both sides.

In the above embodiments, a folding plate having a rectangular wave cross section is shown, but a fold plate having an arcuate cross section may also be used.

<Effects> According to the folding plate structure of this invention configured as described above, since the three-dimensional space on at least one side of the folding plate is covered with a cover, the unevenness of the folding plate on that surface is exposed on the surface. It has a solid feel, and can also be used as a ceiling material for ordinary houses without the troublesome work of conventional ceiling construction, such as using a decorative board to prevent the uneven surface of the folded plate from coming into direct contact with the public. It has very high practical effects, such as requiring no construction, producing a product with a good appearance, greatly simplifying construction work, and being inexpensive.

Moreover, since the linear bending groove 20 is formed along the longitudinal direction of the center of the cover 2, this bending groove 2
The cover 2 can be easily bent about 0 as a fulcrum, and the cover 2 can be easily attached to the folding plate main body 1a, which is very convenient.
