DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a siding material used as an outer wall material of a building and a method of constructing the siding material.

[0002]

2. Description of the Related Art Painted aluminum plates, steel plates and the like are conventionally used as siding materials for buildings. Recently, a molded plate of a thickness of about 0.5 to 5 mm, such as a vinyl chloride resin or a polyolefin, has begun to be used particularly for reforming the outer wall of a building. Such a synthetic resin siding material, compared to the conventional metal plate,
It has the following advantages.

[0003] For example, a siding material made of synthetic resin can be formed by mixing a pigment, so that painting is unnecessary. Further, even if an object collides, it is hardly deformed, scratches are hardly generated, and corrosion resistance is excellent. Further, the deterioration of the material is small and the weather resistance is excellent. It also has advantages such as low cost.

[0004] In the United States and Canada, siding materials made of vinyl chloride resin have been in use for about 15 years.

[0005]

However, when such a siding material made of synthetic resin is to be applied to the outer wall of a new building or a repair building, conventionally, it has been rigidly attached to the outer wall using nails. Therefore, the siding material made of synthetic resin may expand and contract due to a difference in temperature between the outside air and direct sunlight, and the siding material may be warped. In addition, there is a problem that the operation of attaching the siding material using nails is complicated, and the dismantling operation for recycling is also complicated.

The present invention has been made in view of such circumstances, and provides a siding material which can be mounted without using a nail or the like at the time of construction, does not warp, and is easy to recycle, and a construction method thereof. The purpose is to provide.

[0007]

In order to achieve the above-mentioned object, a siding material according to the present invention is a siding material made of a synthetic resin, which is formed at an upper end portion and directly on an outer surface of a base material. A locking claw portion for hanging and holding in a hanging recess formed indirectly or indirectly; and a locking claw portion formed below the locking claw portion and formed at a lower end portion of another siding material. A bulged portion formed with a downwardly-facing concave portion that is locked so as to cover the lower end hook portion, and a hidden concave portion formed at the lower end portion and formed on a bulged portion of another siding material. And a lower end hook portion.

[0008] In the method for applying a siding material according to the present invention, at least the first and second suspending recesses are directly or indirectly provided on the outer surface at predetermined intervals in the vertical direction and substantially parallel in the horizontal direction. The process of extending the formed base material on the wall surface to be repaired or the wall surface of a new building, and in the first hanging recess formed below the base material, the upper end of the synthetic resin siding material The step of suspending and holding the locking claw portion formed at the bottom of the siding material is formed in a hidden recess of a bulging portion formed below the locking claw portion of the siding material. In a state in which the hooked lower end is locked, the locking claw formed on the upper end of the other siding material is suspended in a second suspension recess formed above the base material. And a holding step.

The base material is not particularly limited, and examples thereof include a wooden panel, a metal panel, a plastic board, a gypsum board, and a foamed concrete panel.

[0010] In the first aspect, preferably, the hanging recess formed on the outer surface of the base material is formed on an upper portion of a bar horizontally mounted on the outer surface of the base material. The bar may be formed integrally with the base material, or may be formed separately and attached to the outer surface of the base material with nails or bolts.

When the base material is made of a material having a low bending strength, such as a plastic board or a gypsum board, the bar material may be a nail or a bolt with respect to the structural material disposed inside the base material. It is preferable that they are fixed with such as.

Wooden vertical rims (vertical bars) are attached to the outer surface of the base material at substantially equal intervals, and the bars are horizontally arranged with respect to the vertical rim to form a hanging recess. You may.

[0013] In the second aspect, preferably, the hanging recess formed on the outer surface of the base material is formed at a vertical trunk edge provided at a predetermined distance from the base material. This vertical waist edge may be formed integrally with the base material, or may be formed separately and attached to the outer surface of the base material with nails or bolts. It is preferable that a stud is provided on the back surface of the vertical trunk because the holding power of the siding material becomes stronger through the vertical trunk.

The material of the vertical waist edge is not particularly limited, but a wood material, a plastic material or a metal material such as aluminum is used. Particularly, since the siding material itself is lightweight, the strength of the vertical waist edge itself for holding the siding material is not so required. Therefore, in addition to forming a solid state,
It is also possible to form a hollow section.

The hanging recess formed in the vertical body edge may be formed integrally with the vertical body edge, or may be formed separately and attached to the vertical body edge with nails or bolts.

In the present invention, as a material of the siding material, a thermoplastic resin such as a vinyl chloride resin or a polyolefin is usually used, but polymethyl methacrylate, a styrene copolymer, an acrylate-styrene-acrylonitrile copolymer ( AAS resin), chlorinated polyethylene-acrylonitrile-styrene copolymer (ACS
Any type of synthetic resin such as resin) and fiber reinforced plastic (FRP) may be used.

The synthetic resin plate constituting the siding material is
A single-layer synthetic resin plate or a multi-layer synthetic resin plate may be used.
It is preferable from the viewpoint of separated recycling. For example, a co-extruded two-layer structure using vinyl chloride resin,
It is economical to use a low-cost resin compound mainly composed of recycled materials and to use a virgin resin compound having excellent weather resistance for the surface layer.

[0018] The molding method of the synthetic resin plate constituting the siding material may be, for vinyl chloride resin, a profile extrusion molding method,
A method of molding with a forming die via T-die extrusion is preferably used. In the case of using a polyolefin, injection molding is usually used. When FRP is used, compression molding is preferably used. in this way,
Depending on the type of synthetic resin plate that makes up the siding material,
What is necessary is just to employ | adopt the molding method suitable for each.

The size of the siding material is not particularly limited, but usually, in the case of an extruded product, the vertical dimension is 10 mm.
0-400mm, horizontal dimension 1000-5000mm, in case of injection molded product, vertical dimension 500-1000mm, horizontal dimension 5
It is preferably about 00 to 1500 mm. Also, the thickness of the siding material is not particularly limited, but is preferably about 0.5 to 10 mm.

In the present invention, additives such as pigments, processing aids, heat stabilizers, and ultraviolet absorbers are added to the synthetic resin plate constituting the siding material, if necessary.

[0021]

In order to spread the siding material according to the present invention on the outer wall surface of a new building or a building to be repaired, the engaging claw formed at the upper end of the siding material is directly attached to the outer surface of the base material. It is only necessary to suspend and hold the suspension recesses formed indirectly or indirectly. The lower end hook portion formed at the lower end of the siding material can be engaged with a downward hidden recess formed at the swelling portion of the siding material located therebelow.

Therefore, the locking claw portion formed on the upper end portion of the siding material is covered with the lower hook portion of the siding material disposed thereabove, and the locking claw portion is erroneously locked. Is not canceled.

As described above, according to the present invention, the siding material can be attached without using a nail or the like at the time of construction, and the siding material does not accidentally come off the base material. In addition, since the synthetic resin siding material can be attached to the base material without using nails, even if the synthetic resin constituting the siding material undergoes thermal expansion and contraction, it can freely move with respect to the base material, warp, etc. Does not occur.
Further, when the siding material is removed and disassembled, the siding material can be easily removed from the base material by an operation reverse to the case of construction, and recycling is easy.
