Description

Description: TECHNICAL FIELD The present invention relates to a building hollow member in which a hollow portion is formed by a peripheral wall portion.

(Prior Art) Conventionally, as a building member, a member cut out from a tree is generally used as shown in FIG.

Further, as an assembly member, as shown in FIG. 6, an I-shaped member and a further improved member thereof are available.
Lamination of thin veneers as seen in Japanese Patent Publication No. 18972,
There is a laminated member for structural member in which the back portions of the U-shaped base material formed by bending are joined to each other and integrated.

(Problems to be solved by the invention) However, since the one cut out from the above one tree has low yield strength, it has to be made thick in order to improve the strength, and as a result, the weight increases and other factors in the structure are increased. There is a problem that not only the strength of the part is strengthened but also the workability is deteriorated.

On the other hand, the above-mentioned conventional assembly member can be lightened, but since it has an I-shape, it has a problem that it is difficult to connect with other members, and it is used in a room. However, there is a problem in that the appearance is not preferable.

Further, the conventional assembly member shown in FIG.
0 and 20 and the connecting member 21 are different in the laminating direction of the thin veneer (horizontal direction in the upper and lower members 20, connecting member 2
1 in the vertical direction), the upper and lower members 20, 2
0 and the connecting member 21 have to be separately produced and then joined, and at this time, it is necessary to treat the joining end surface of the connecting member 21. Therefore, there is a problem that the manufacturing work is complicated.

The object of the present invention is to solve the problems of the conventional members as described above, easy to join with other members, have a good appearance and can be used so as to be exposed indoors, and are simple to manufacture. An object of the present invention is to provide a hollow building member that can be made lightweight.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention is a building hollow member in which a hollow portion is formed by a peripheral wall portion, and the peripheral wall portion is laminated by laminating thin single plates. It is characterized in that it is composed of a body and the laminating direction of the thin veneers is one direction over all the peripheral wall portions.

Further, the axis of the hollow building member of the present invention may be non-linear, and the cross-sectional shape may be quadrangular, triangular, pentagonal or higher polygonal, circular, or elliptical.

(Function and Effect) The hollow member for construction of the present invention has the above-described structure, and therefore has the following function and effect.

That is, since it is hollow, it is possible to reduce the weight while obtaining the required strength.

Further, since the outer shape is a tubular shape such as a square tube, it is easier to join with other members as compared with the conventional I-shaped one. At this time, by press-fitting the joint member into the hollow portion, it is possible to join the other member extremely easily and firmly.

Further, even when it is used so as to be exposed to the room, it does not spoil the aesthetics of the room as compared with the conventional I-shaped one. In addition, the cross-sectional shape can be properly used depending on the interior, such as a quadrangle, a triangle, or a circle, and the axis can be non-linear, that is, curved, so that the decorative effect can be further improved. .

Further, the peripheral wall portion can be formed only by laminating thin veneers, and since the laminating direction of the thin veneers is one direction over all the peripheral wall portions, simply laminating the thin veneers sequentially. A building hollow member can be completed.
Further, even when the peripheral wall portions are separately produced and then joined, the lamination surface of the thin veneer is in one direction over all the peripheral wall portions, and therefore the treatment of the joint surface is unnecessary. Therefore, its manufacture can be easily performed.

(Example) Hereinafter, the illustrated example will be described.

1 (a) to 1 (g) are perspective views showing a first embodiment of a building hollow member according to the present invention, wherein FIG. 1 (a) is a square tubular member, and FIG. 1 (b) is a triangle. The cylindrical shape is shown in (c), the cylindrical shape is shown in (d), and the pentagonal shape is shown in (e).
The figure shows a hexagonal tube, the figure (f) shows a cross,
(G) The figure shows an elliptic cylinder.

Each of these has a hollow portion A formed by a peripheral wall portion, and is characterized by laminating thin wood veneers in one direction over all peripheral wall portions.

In FIG. 1 (a), reference numerals 1 and 1 are side wall portions, 2 is a bottom wall portion, 3 is a top wall portion, and these peripheral wall portions are thin single plates 1a, respectively.
.., 2a .., 3a ..

(B) In the figure, 4 is a peripheral wall portion forming a triangular cylindrical peripheral wall, which forms a thin single plate 4a forming a bottom wall, a thin single plate 4b forming a side wall, and a top portion. Thin veneer 4
It is configured by sequentially stacking and fixing c.

In the figure (c), 5 is a cylindrical peripheral wall portion, which is formed by sequentially laminating and fixing thin single plates 5a.

In the figure (d), 6 is a pentagonal tubular peripheral wall portion, which is a thin veneer 6a forming the bottom wall, and a thin veneer 6 forming the side wall.
b, and thin single plates 6c forming the top are sequentially laminated and fixed.

In the figure (e), reference numeral 7 denotes a hexagonal tubular peripheral wall portion, which is a thin veneer 7a forming a bottom wall, ..., A thin veneer 7 forming a side wall.
, and thin single plates 7c forming the ceiling wall are sequentially laminated and fixed.

In the figure (f), 8 is a substantially cross-shaped peripheral wall portion,
A thin veneer 8a forming the bottom wall, a thin veneer 8b forming the side wall, and a thin veneer 8c forming the ceiling wall.
Are sequentially laminated and fixed.

In the figure (g), 9 is an elliptic cylindrical peripheral wall portion, which is formed by sequentially laminating thin single plates 9a ...

As described above, in the building hollow member, since the laminating directions of the thin single plates are the same over all the peripheral wall portions,
It can be easily made by sequentially laminating and fixing each single plate in the same direction.

In addition, in the present embodiment, it is only necessary to sequentially laminate and fix thin veneers formed in a predetermined shape in the same direction, so that the axis C has a crank shape as shown in FIGS. 2 (a) and 2 (b). And L-shaped ones can be easily created. That is,
Thin veneer 10 previously formed in crank shape or L-shape
··························

In addition, in the case of each of the present examples, each has a large strength against the load P from the direction perpendicular to the laminating direction of the thin single plates.

Although the embodiments of the present invention have been described above, since each embodiment has the hollow portion A, it is possible to achieve weight reduction while obtaining required strength.

Further, even when it is used so as to be exposed to the room, it does not spoil the aesthetics of the room as compared with the conventional I-shaped one. Moreover, the cross-sectional shape can be properly used depending on the interior, such as a quadrangle, a triangle, or a circle, and the axis line can be non-linear, that is, curved as shown in FIG. The effect can be further improved.

In addition, since the outer shape is a tubular shape such as a square tube, connection with other members becomes easier as compared with the conventional I-shaped one. At this time, the joint member can be extremely easily and firmly connected by press-fitting the joint member into the hollow portion.

3 and 4 show the connection state in the case of a hollow member such as a square.

In these drawings, D is a hollow cylindrical member, A is a hollow portion, and J is a joint member.

As shown in FIG. 3 (a), the joint member J is press-fitted into the hollow portions A of the two rectangular tubular hollow members D, D to be connected,
Both members can be connected easily and firmly by adhering as needed.

As a result, as shown in FIG. 4B, by connecting a large number of hollow rectangular hollow members D by the joint members J, it is possible to realize an extremely long member that could not be realized conventionally. Moreover, since the member D is a single body before being connected by the joint member J, it can be easily transported to the construction site and carried into the structure, and the structure can be constructed with suitable workability.

Further, as shown in FIG. 4, both members D, D which are orthogonal to each other can be connected easily and firmly by using the joint member J.

In such a connected state, the joint member J is housed in the hollow portion A and is not exposed to the outside, so that the appearance is not spoiled.

Although the embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the above embodiments and can be appropriately modified within the scope of the gist of the present invention.

For example, it is also possible to form each peripheral wall portion in advance, and join and fix the peripheral wall portion to create it. Even in this case, since the laminating direction of the thin veneer is one direction over all the peripheral wall portions, it is not necessary to treat the bonding surface, and the manufacturing is easier than that of the laminating veneers having different laminating directions.
