Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal siding that can be constructed without using a covering corner corner member for covering the corner corner when applying a metal siding material to the exterior of a house. About materials.

[0002]

2. Description of the Related Art As a metal siding material 1 to be installed on the exterior of a house, both sides in the width direction of a metal band as shown in FIG. A female fitting part 4 indented inside the flat part 2 on one side wall 3 can be fitted to the female fitting part 4 on the other side wall 3a while forming a gutter-like body provided with 3a. A male fitting portion 5 protruding outward from the flat portion 2 is formed along the longitudinal direction, and a mounting piece 6 protruding from the male fitting portion 5 is provided on the back side of the male fitting portion 5. In general, a foam resin 8 such as urethane is filled in a gutter of the surface material 7 provided, and a back material 9 is fixed to the surface of the foam resin 8. In order to enhance the design of the flat portion 2, An embossed pattern is provided or a groove pattern 10 is provided in the longitudinal direction.

[0003] When the metal siding material 1 is constructed, the corner is exposed at the corner of the house, so that the corner is exposed.
Conventionally, this cover is provided as a corner member 11 with a female fitting ridge 13 on the outer corner portion of the angled member 12 as shown in FIG. A lower die 14 made of synthetic resin and a male fitting ridge 16 provided on an inner corner portion of the angled member 15 and an upper die 18 made of synthetic resin having an outer side covered with a painted metal plate 17, Before the metal siding material 1 is applied, the lower mold 14 is previously struck onto the base material 19 of the house so that the female fitting ridge 13 is on the outside. In this method, the ridge 16 is fitted to the female fitting ridge 13 of the lower mold 14.

[0004] In the case of covering the outside corner by this method, usually,
The metal siding material 1 and the corner member 11 are in harmony by using an upper die 18 in which the angled material 15 is covered with a painted metal plate 17 of the same color and the same pattern as the metal siding material 1. If the metal siding material 1 has a large groove pattern 10 as shown in FIG. 8 and needs to be kept in a continuous state after the application, the upper die 18 is grooved by a painted metal plate 17 provided with such a groove pattern 10. Since it is difficult to coat the pattern 10 without damaging it, the one coated with the painted metal plate 17 without the groove pattern 10 was used. For this reason, there is a problem that the groove pattern 10 of the metal siding material is partially cut off at the corner of the house, resulting in a poor appearance of the house.

[0005]

The present invention does not require the corner member to be covered with such a corner member.
In addition, the present invention provides a metal siding material for a corner at a corner where a large uneven pattern can be made continuous.

[0006]

According to the first metal siding material of the present invention, a metal strip is formed into a gutter-like body, and a female fitting portion is provided on one side wall in the width direction of the gutter-like body, and the other is provided with the female fitting part. By forming along the longitudinal direction both the female fitting portion and the male fitting portion which can be fitted on the side wall of the surface material, a foam resin is filled in a gutter of the surface material, and the foam is further formed. In a metal siding material in which a back material is fixed to the surface of a resin, a V-shaped notch groove of about 45 ° extending perpendicularly to the longitudinal direction is formed linearly in the entire width of the back material side. After providing a continuous V-shaped notch in the female fitting portion, the male fitting portion and the mounting piece, the foamed resin and the back material, the paper is bent at a right angle from the V-shaped cut groove toward the back material side, and inside the bent portion. It was bent at a right angle and the backing material was fixed.

In the first metal siding material, a coking material is applied from the inside of the bent portion to a portion of the first metal siding material which is brought into contact with the female fitting portion and the male fitting portion by bending. Thereafter, the backing material was fixed.

[0008]

The first metal siding material is bent at a right angle in the longitudinal direction in a state where the flat portion of the surface material is continuous, so that rain does not invade even if it is applied to the corner at the protruding corner. For this reason, there is no need to cover using a corner corner member as in the related art. Further, since this metal siding material is obtained by bending a flat material at a right angle, the appearance is the same after bending. For this reason, even if a large groove pattern is formed in the longitudinal direction, both groove patterns can be made continuous. Furthermore, V is applied to the back material side of the flat metal siding material.
When a U-shaped cut groove is formed and bent at a right angle to the back material side, the strength of the bent part is mainly only the flat part of the surface material and the strength in the front and back direction is weak, but it is bent at the right angle inside the bent part and lined Since the material is fixed, there is no damage or breakage during handling or construction. As this backing material, a corrosion-resistant metal plate such as a zinc-iron plate or a colored zinc-iron plate, which is bent at a right angle, is used, and is fixed inside the bent portion. This fixing method is to wrap the longitudinal end side of the backing material around the female fitting part or mounting piece of the surface material, and to fix it to the back material side or mounting piece of the female fitting part with connecting parts such as screws or rivets Or a method of bonding the entire length or a part of the backing material with an adhesive or double-sided tape.

In the case where the second metal siding material is the first metal siding material, there is a cut even if both sides provided with the V-shaped cuts of the female fitting portion and the male fitting portion abut against each other by bending. In the case of severe wind and rain, rainwater penetrates from there, and in order to prevent this, a coking material is applied to the butt portion from the inside to completely finish the rain.

In the case of connection in the width direction, the metal siding material is applied to a house by fitting a female fitting portion and a male fitting portion of the connecting members.
A V-shaped notch of about 45 ° is formed on the back material side of the flat metal siding material with the second metal siding material,
Since the shape of the female fitting portion and the male fitting portion is bent so as to be maintained in the state before bending, the connection in the width direction can be performed similarly to a flat metal siding material.
In the case of connection in the longitudinal direction, a connection member (connection joiner) is used. However, since the end portions are the same as those of the conventional metal siding material, they can be connected by the same method. The dimension of the metal siding material of the present invention is that a flat metal siding material having a length of 80 to 100 cm is formed with a V-shaped notch groove at the center in the longitudinal direction and bent at a right angle in terms of manufacturing, handling, transportation, construction and the like. Is preferred.

Cuts the conventional flat metal siding material 1 shown in FIG. 8 into a predetermined length at a right angle in the longitudinal direction as shown in FIGS. A V-shaped cut groove 21 of about 45 ° is formed linearly at right angles to the longitudinal direction, and the female fitting portion 4, the male fitting portion 5 and the mounting piece 6 of the surface material 7, and the foamed resin 8 and After a parallel cut or V-shaped cut is provided by partially removing the back material 9, the V-shaped cut groove 2 is formed.
It is bent at right angles to the back material 9 side around 1 to form a mountain shape.

By this bending, the female fitting portion 4, the male fitting portion 5, and the mounting piece 6 on both sides of the V-shaped cut groove 21 of the surface material 7 abut, but there is a cut. Therefore, the coking material 22 is applied to the cuts of the female fitting portion 4 and the male fitting portion 5 where there is a possibility of rainwater intrusion. After the coking material 22 is applied, a backing material 23 formed by bending a metal plate such as a zinc iron plate or a colored zinc iron plate at a right angle is fixed to the back material 9. In this fixing, one end in the width direction of the backing material 23 is fixed to the mounting piece 6 with a screw 24 as shown in FIG. 3, and the opposite end is a female fitting portion 4 as shown in FIG.
Although it is wound around the inside, it may be fixed with an adhesive or double-sided tape.

FIG. 7 shows the state of construction of the metal siding material 20. A mounting piece 6 is hit on the protruding corner, and the end is a connecting material 27 comprising a lower mold 25 and an upper mold 26, which is a conventional metal siding material. It connects with the end of the siding material 1.

[0014]

As described above, the metal siding material of the present invention is bent at a right angle without losing the shapes of the female fitting portion and the male fitting portion and reinforced with a backing material. It can be installed in houses as well as flat metal siding. Therefore, no corner corner member is required,
Also, the pattern of the metal siding material can be matched. Also, if a coking material is applied to the butted portions on both sides of the V-shaped cut of both fitting portions, it is possible to prevent rainwater from entering.
