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 corners to be attached as a base treatment of a corner portion before sticking a wall material to an indoor wall surface , and a corner material for an indoor wall using the corner material . place
Related to the management 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 type of wall covering, it is necessary to finish the ground surface with no unevenness in order to obtain a beautiful finish, and how the ground treatment has a great effect on the finish. Was. As these wall base materials, it is common to use plywood called a plaster board or a so-called control panel, and these surfaces are not necessarily smooth due to cut surfaces or jointed joints. Finishing out the corner was quite difficult. In addition, even when the construction was initially processed and finished for the time being, it was often the case that defects were later revealed due to secular changes and impacts on the corners.

[0003]

2. Description of the Related Art Conventionally, in order to solve these problems, though not shown in the drawings, a soft or hard synthetic resin having a thickness of 1 mm or less and a width of 2 mm or less, Furthermore, a corner material has been devised in which two long flat plate-like plate members made of metal are connected to each other in the longitudinal direction by hinges, and a large number of perforations are formed in the surface of the plate member. (Junko Sho 62-40030
issue).

In such a corner material, a hinge portion is applied to a protruding corner portion of a building, this portion is bent at a right angle, and flat plates on both right and left sides are respectively adhered to a wall surface base material (eg, a gypsum boat) with an adhesive or the like. Is used to flatten the corner. The width of the hinge portion is set to 2 mm or less in order to sharpen the edge of the corner.

[0005] Further, as an improvement, the same structure as described above, except that two types of folds are formed in the hinge portion, so that both a sharp corner and a rounded corner are formed. Corner materials have been devised that make it possible to deal with (Japanese Utility Model Laid-Open No. 6-35475).

[0006]

The corner material described above is
A wall base material such as a plaster board is attached so as to cover the pillars constituting the protruding corner, and the protruding corner is formed by butting from both sides, and the abutting portion (corner edge) is flattened for the purpose of flattening the abutting portion (corner edge). It was mounted so as to cover the part, and its thickness had to be as thin and inconspicuous as possible. For this reason, it is made of a synthetic resin or a thin metal plate, and a large number of perforations are provided to improve the application of the adhesive.

[0007] However, these materials have a large coefficient of thermal expansion and are not so noticeable at the beginning of construction. However, a phenomenon has been observed in which the dimensions become larger than the initial dimensions due to repeated expansion and contraction over many years. The deviation of the dimensions spreads over the wall covering material, causing a problem in that the appearance is bulged or cracks are generated and the appearance is impaired.

Further, since the perforations are formed, the adhesive also affects the back surface of the wall covering, and after a long period of time, the surface of the wall covering becomes apparent as spots or discoloration, which is another problem. Had become.

Furthermore, since these corner members are molded products, a mold for molding is required, which has been expensive.

[0010]

Therefore, the present invention has been made in view of the above-mentioned problems, and can be manufactured easily and inexpensively by cutting a square bar of a commonly available standard, and using wooden materials. Because of this, it is possible to improve the familiarity with the pillars at the corners , so that the finish of the corners is good and the corner material that does not show any trouble even after a long period of time. Outer corner of indoor wall used

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the corner material of the present invention will be described in detail with reference to the drawings. FIG. 1 is an intermediate omitted perspective view of a protruding corner material according to the present embodiment, FIG. 2 is a plan view showing a cut end thereof, FIG. 3 is a perspective view showing an attached state of the present embodiment, FIG. 4 is a perspective view for explaining the mounting process.

The corner material 1 is made of a wooden material such as a veneer, a plywood, a chip material or a compression-formed plate of wood flour, etc., and is made of long rectangular prism-shaped wood having a rectangular wood mouth 2 from the wood mouth 2 on one end side. It has a shape cut into a rectangular cross section including a corner 30 on one side along the length direction across the other end 2b. The cutting surfaces 31a and 31b of the cutting portion 3 are formed so as to be orthogonal and parallel to the side surfaces 4a and 4b of the corner material 1 facing each other. The width W of the side surface 4c in contact with the cut portion 3 is formed to be the same, and the width W is the thickness T of the plaster board 5 as the wall surface base material to be contacted.
Set almost the same as.

Further, the thickness H of the cut portion 3 is set to be smaller than the width W of the side surface, so that the thickness H can be applied to a protruding corner having a small protruding amount. In addition, the corner 6 which is diagonal to the corner 30 of the cutting portion 3 may have a square shape as it is, but may be slightly rounded or chamfered 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 cut part is 52.5m
m × (H) 5.5 mm. As a result of this cutting , the width W of the side surface 4c in contact with the cutting portion 3 is the same, that is, 12.5 mm. When mounting, this surface 4
c is brought into contact with an edge surface (or a cut surface) 50 of the plaster board 5 serving as a wall surface base material.

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, and when a compression-molded material such as wood powder is used, it may be molded. .

According to the above configuration, the corner processing using the corner material 1 is performed by first cutting the corner material 1 with a saw or the like in accordance with the mounting height (for example, ceiling height), and then forming the corner. The orthogonal cutting surfaces 31a and 31b are attached to the corners 70 of the pillar 7 to be brought into contact with each other and fixed with an adhesive or a wood screw. Next, the edge surface 50 of the plaster board 5 is abutted on the side surface 4c abutting at right angles to the cutting surface 31, and is fixed to the pillar 7 or a stud (not shown). Then, if necessary, a joint material such as putty is filled so as to fill the gap between the contacted joint portions 8 and smoothed. After the processing, finishing is performed by attaching a wall covering material 9 such as a wallpaper so as to surround the upper surface of the corner material 1.

[0020]

As described above, since the present invention is formed by processing a wooden timber of an existing standard size, it can be manufactured at a low cost, and since it is made of wood, it can be adjusted to the mounting height at the site. It can be appropriately cut for use.

Further, since it is made of natural wood, it has good adaptability to pillars, has no remarkable effect of thermal expansion, and has a remarkable effect that troubles hardly occur even after many years of use. With the corner material having the above effects, it is possible to reliably and inexpensively perform the groundwork treatment in attaching the wall covering material to the inside corner of the room, and it is possible to clean the finished surface, It has a remarkable effect that the state can be maintained for a long time.
