Description

[Technical Field] The present invention relates to a columnar body made of a composite material, which is a columnar body for a building structure used as a column for a general house,
The present invention relates to a composite material formed by combining a plurality of materials.

<Prior Art> As the above-mentioned pillar for a general house, one lumber that is normally lumbered is used as it is, but in recent years, it has become difficult to obtain a high-quality timber due to a decrease in wood resources. It was
Further, in the case of timber, if it is not used in a sufficiently dried state, there is a problem that it may warp or be deformed after construction, resulting in deformation of columns or misfitting of fittings and the like.

Therefore, if a high quality timber is used or if sufficient time is taken for drying, the raw material cost becomes very high, the construction efficiency is deteriorated, and the cost of the house is increased.

Therefore, instead of timber, it has been proposed to combine plywood into a rectangular tube shape or to use a hollow column made of a metal pipe. However, if the plywood is combined into a rectangular tube shape, it is possible to prevent bending and deformation. It is not strong enough, and when it hits the side, it reverberates inside, producing a high-pitched hollow sound, giving it an extremely thin feel compared to conventional solid timber, and a poor usability. There is.

Further, in the case of a metal pipe material, the strength and the difficulty of deformation over time are sufficient, but the cost is very high, and cutting and mounting are technically difficult. Moreover, the above-mentioned hollow sound at the time of hitting becomes a metallic sound that is higher and more offensive than that of plywood, and is not suitable for general housing.

<Purpose> Therefore, an object of the present invention is to provide a columnar body which solves the above-mentioned problems of the prior art, has a strong strength, is hard to be deformed with time, produces a solid sound similar to timber, and is inexpensive in cost. To do.

<Structure> And, as a structure for achieving the above object, a unit piece having a predetermined thickness obtained by cutting a laminate of a long thin plywood and a synthetic resin foam along the longitudinal direction. And a thin plywood along the horizontal direction are alternately stacked and joined via an adhesive, and the plywood along the vertical direction and the plywood along the horizontal direction are arranged in a matrix of vertical and horizontal directions. A frame-like body is formed in a state in which the partition space is sectioned, and the plurality of partition spaces are filled with the foam.

<Embodiment> Next, an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall shape of the columnar body (c), which is formed in a prismatic shape similar to the columnar material made of normal timber,
(1) shows a frame-shaped body made of plywood, and (2) shows a foamed body of synthetic resin.

Then, the frame-shaped body (1) constitutes a prismatic outer shell of the columnar body (c) by the thin plate-shaped plywood, and at the same time, the frame-shaped body (1).
Inside, the plywood is arranged in a matrix in the vertical and horizontal directions to form a large number of square-shaped partition spaces (10) partitioned by the plywood. Further, the foam body (2) fills the partition space (10) formed inside the frame-like body (1) without a gap, and the plywood (1) and the foam body (2) are appropriately bonded by an adhesive. , Are integrally joined. Therefore, only the plywood (1) is exposed on the outer surface of the columnar body (c), and the foamed body (2) is embedded inside.

Usual plywood for construction can be used as the plywood, and foams made of polystyrene, polyethylene, and various other thermoplastic resins can be used as the synthetic resin foam (2). Further, as an adhesive agent for joining the frame-shaped body (1) and the foamed body (2), a wooden frame-shaped body (1) and a foamed body (2) are used.
An ordinary adhesive for woodworking or synthetic resin can be used as long as it has good adhesiveness to any of the synthetic resins constituting the above.

Next, an example of a method of manufacturing the columnar body (c) described above will be described with reference to FIGS. 2 and 3.

First, a relatively thin plywood (v) and a board-shaped foam (2) that is considerably thicker than the plywood (1) are prepared. In order to manufacture the board-shaped foam (2), the foam (2) having a predetermined thickness is extruded from a predetermined thermoplastic resin, and the block-shaped foam is formed by molding. After the body is manufactured, it may be sliced to a predetermined thickness for use. However, in terms of production efficiency and strength, extrusion foaming is preferable.

Then, as shown in FIG. 2, the plywood (v) and the foamed body (2) are alternately stacked with an adhesive in between, and the whole is pressed to integrally laminate and bond them. The layered body (s) of the plywood (v) and the foam (2) produced in this manner is
A unit piece (having a plate-like shape with a constant thickness, in which the plywood (v) and the foam (2) are alternately laminated in the direction along the cut surface by cutting and separating from the end portion at a constant width ( b) is produced.

Next, as shown in FIG. 3, plywood (1) and foam (2)
The unit pieces (b) in which and are alternately stacked and the separately prepared plywood (v) are alternately stacked with an adhesive between them and integrally joined. At this time, in each unit piece (b), the unit pieces (b) and the plywood (v) are stacked in a state where the plywood (v) and the foam (2) are alternately arranged in the horizontal direction,
The columnar body (c) is manufactured in a state where each foamed body (2) of the unit piece (b) is surrounded by plywood (v) in the top, bottom, left, and right in a grid pattern.

However, as the method for producing the columnar body (c), in addition to the above-mentioned method, a method in which only the frame-shaped body (1) is first formed and then the foam body (2) is embedded in the internal partition space (10), or the like. , Can be implemented.

The columnar body (c) manufactured as described above can be cut into an appropriate length and used in the same manner as an ordinary column material,
When it is used as a pillar of the part exposed in the interior of a house, as shown in FIG. 4, a decorative material (3) such as a printed plywood or wallpaper material is attached to the outer surface of the pillar (c). If you keep it
The outer surface of the columnar body (c), particularly the seam of the plywood (1) is not exposed on the outer surface, and can be used in good appearance.

Of the columnar bodies (c) having the above structure, the columnar body (c)
In addition to the square shape shown in the figure, it is possible to manufacture a rectangular shape having different vertical and horizontal lengths, or an L-shaped or other different shape, which corresponds to the shape of the columnar body (c). The structure of the frame-like body (1), that is, the way of combining the plywood (v) forming the frame-like body (1) is different. Then, in the above-mentioned manufacturing method, the number of stacking steps of the plywood (v) and the foam (2), the combination of the unit pieces (b), etc. at the time of manufacturing the layered body (s) are appropriately changed. carry out.

The columnar body (c) of the present invention can be suitably used as an ordinary column member for houses, and can also be used as various columnar structural materials for construction such as beams and floor materials.

<Effect> According to the columnar body (c) of the present invention configured as described above, a laminated body (a long thin plate-like plywood (v) along the longitudinal direction and a synthetic resin foam (2) ( In the state where the unit pieces (b) having a predetermined thickness obtained by cutting s) and the plywood (v) having a thin plate shape along the lateral direction are alternately stacked and joined via an adhesive, each plywood ( v) by the grid-like frame (1)
Therefore, by setting the number of laminated unit pieces (b) to a desired value, it is possible to easily form columnar bodies (c) having various specifications and having a grid-like frame-shaped body (1). This makes it possible to reduce the manufacturing cost when manufacturing the columnar bodies (c) having a plurality of specifications having the lattice-shaped frame body (1).

The frame-shaped body (1), which is formed by combining and joining the plywood (v) with less warpage and deviation, maintains sufficient strength and deformation resistance as the columnar body (c). 1) not only constitutes the outer shell of the columnar body (c),
Since a plurality of plywoods (v) for partitioning the inside into a plurality of partition spaces (10) are combined in a lattice shape aligned vertically and horizontally and arranged in a state of strong connection, a frame-like body ( The strength of 1) is remarkably improved, and it is possible to exhibit high deformation strength and load resistance comparable to the conventional pillar made of one timber. Moreover, in the case of solid timber, there is a concern that it may warp or deform after construction unless it is dried sufficiently after it has been lumbered, but if it is a frame-like body (1) made of plywood (v), it will be deformed over time. There is almost no possibility of this, and accurate shape maintenance can be achieved over a long period of time.

Then, when the columnar body (c) alone is hit with the frame-shaped body (1), the impact sound reverberates in the cavity defined by the internal partition space (10), and a high and extremely offensive sound is generated. The partition space (10) of the shaped body (1) is replaced with a synthetic resin foam (2).
Since it is filled with, it produces almost no reverberant sound and gives a low-class, high-class impact sound that is close to that of conventional solid timber, and is used as a pillar material that is comfortable and reassuring to residential residents. be able to.

Moreover, by filling the partition space (10) of the frame-shaped body (1) with the foamed body (2), the foamed body (2) having an elastic reinforcing effect and an excellent heat insulating property can form a columnar body. (C) The heat insulating property of the whole can be improved.

Furthermore, the columnar body (c) composed of the frame-shaped body (1) and the foamed body (2) is much lighter in weight and easier to transport and handle than the conventional solid timber, and can be used as a foundation or a post-construction foundation. The load on the floor material is also reduced.

As described above, according to the columnar body (c) of the present invention, compared with the conventional solid timber, there is no warp or deformation, it is lightweight and easy to handle, and the impact sound is close to that of timber. It is possible to exert various excellent practical values such as feeling.
