Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner material for a corner to be attached as a base treatment for a corner before the wall covering material is attached to an indoor wall, and a corner material for an indoor wall using the corner material. Regarding the processing method.

[0002]

BACKGROUND OF THE INVENTION In recent years, wall coverings such as paper, cloth, and synthetic resin sheets have been used for indoor walls of many buildings. When sticking this kind of wall covering, in order to obtain a beautiful finish, how the underlayer treatment greatly affects the finish,
It was necessary to finish the underlying surface to a smooth surface without irregularities. As these wall base materials, for example, plywood called a plaster board or a so-called control panel was generally used. However, defects are apt to occur due to gaps in the cut surface of the wall base material and joints, etc., so that it is very difficult to finish the corners. In addition, even if the work is neatly processed and finished at the beginning of construction, defects often appear later due to aging and impact on the corners.

[0003]

2. Description of the Related Art The problem of the processing at the inside corner is the same as that at the outside corner. To solve this problem, the drawing is omitted, but the thickness is 1 mm or less and the width is 2 mm or less. Two long flat plate-shaped plate members made of synthetic resin or metal are connected to each other at their longitudinal ends by hinges, and a corner member formed by forming a large number of perforations on the surface of the plate member. One that was applied to the outer corner was invented (Japanese Utility Model Publication No. 62-40030).

In such a corner material, a hinge portion is applied to a protruding corner portion of a building, and this portion is bent at a right angle, and flat plates on both right and left sides are respectively adhered to a wall base material with an adhesive or the like to form the corner portion. Is to be flattened. The width of the hinge portion is set to 2 mm or less in order to sharpen the edge of the corner. In some cases, the edges were rounded (Japanese Utility Model Laid-Open No. 6-35475).

[0005]

When the above-mentioned corner material for an outgoing corner is applied to the ingoing corner, the ingoing corner is formed by abutting a wall base material from a direction perpendicular to a pillar constituting the ingoing corner. However, in order to flatten the butted portion, the corner portion (the inner corner of the right angle portion) is mounted so as to cover the corner portion, so that the thickness of the corner material must be as thin and inconspicuous as possible. there were. For this reason, the corner material is made of a thin synthetic resin or a thin sheet metal, and a large number of perforations are provided to improve the application of the adhesive.

However, since the above-mentioned corner material is adhered on the wall base material, even when a very thin corner material is used, a slight step occurs between the wall base material and the corner material. Therefore, it has been necessary to use a large amount of putty material and perform a base treatment for wall covering work so that those surface portions are apparently uniform.

[0007] In addition, these thin plate-shaped materials are not so noticeable at the beginning of the construction, because the difference in coefficient of thermal expansion has a great effect.
After a long period of time, a phenomenon was observed in which expansion and contraction were repeated and the dimensions became larger than the initial dimensions. The deviation of the dimensions has caused a problem that the wall material is swelled or cracked and the appearance is impaired.

Further, when the perforations are formed, the adhesive also affects the back surface of the wall covering, and after a long period of time, stains and discoloration on the surface of the wall covering become apparent. Was also a problem.

[0009]

Accordingly, the present invention has been made in view of the above-mentioned problems, and can be manufactured simply and inexpensively by removing a square material of a standard that is generally available, and using a wooden material. As a result, the corners can be easily blended with the pillars and torso at the corners, thereby improving the finishability of the corners and avoiding the appearance of defects due to aging. It is intended to provide a material and a method for treating an inside corner of an indoor wall using the same.

[0010]

In order to achieve the above-mentioned object, a corner material to be attached to an inner corner of an indoor wall according to the present invention is formed from a predetermined rectangular shape and has two corners which are orthogonal to one corner of the corner. It is formed in a long columnar body having an L-shaped cross-sectional shape that is formed by cutting a rectangular shape including a side with a predetermined length, and extending in the longitudinal direction facing the L-shaped orthogonal radiation direction (D). The two extending side surfaces (11, 12) are formed to be flat and the width (W) thereof is set to be the same as the thickness (T) of the wall base material.

The long column having the L-shaped cross section is formed from a long rectangular column including a corner extending in the longitudinal direction and a predetermined width of two side surfaces orthogonal to the corner. The elongated rectangular prism (2) to be formed may be deleted and formed. In addition, the maximum side surface (30) of the long rectangular prism (30) is used.
a) On one side of the surface in the short side direction (30)
An elongated rectangular prism (31) smaller than this may be formed integrally with the corners (30b, 31a) aligned at a position closer to b).

Next, a method for treating an interior corner of an indoor wall using the interior corner material having the above structure is as follows. First, the interior corner material (1, 3) is placed at the height of the interior corner of the interior wall. And cut into the corner material (1, 3) for the corner on the convex side (14).
a, 14b) are attached and fixed to the corners, and then the wall base material (4) is attached to the side surfaces (11, 12) orthogonal to the convex orthogonal surfaces (14a, 14b), respectively. ) Is fixed to the torso rim (6) or the stud in a state where the edge surface (40) is in contact with the edge surface (40).

It has a shape in which the elongated quadrangular prism body 2 including the corner portion 20 on one side along the length direction over the end side is deleted. Then, the two longitudinal side surfaces 11, 12 facing the L-shaped orthogonal radiation direction D
Are formed flat, and the width dimension W thereof is set to be the same as the thickness T of the wall base material 4 to be abutted.

The thickness H of the quadrangular prism 2 to be deleted is:
The width W is set to be smaller than the width W of the side surface, so that it can be applied to a corner having a small corner amount. Note that the inner corner 13 on the inner corner side that is orthogonal to the corner may be slightly rounded if necessary.

The dimensions of this embodiment are such that the cross-sectional shape before processing is 65
mm × 18mm, the cross section of the deleted part is 52.5m
m × (H) 5.5 mm. Thereby, two longitudinal side surfaces 11 facing the orthogonal radiation direction D of the L-shape,
Twelve widths W are the same size of 12.5 mm. In the above embodiment, the corner material 1 is formed by shaving from a square material. However, the present invention is not limited to this. When a compression-molded material such as wood powder is used, the shape of the L-shaped columnar body is used. It may be molded.

Further, as shown in FIG. 2, the smaller rectangular prism 30 is positioned on the largest side surface 30a of the large rectangular prism 30 near the corner 30b extending in the longitudinal direction. The corner member 3 of the long columnar body having an L-shaped cross section may be formed by attaching the rectangular sides 31a of the long rectangular column 31 so that the corners 31a thereof are aligned. [Construction method]

With the above configuration, the corner processing using the corner materials 1 and 3 is performed by first cutting the corner materials 1 and 3 with a saw or the like in accordance with the mounting height (for example, ceiling height).
