Abstract

(57) [Summary] (Modified) [Purpose] A corner material that attaches to a corner portion of a wall and flattens that portion, with rounded corners and rounded corners. The corner part is constructed with one kind of corner material. [Structure] Thickness is less than 1 mm and width is 2 mm
A fold line 4 is formed along the longitudinal direction in the central portion in the width direction of the synthetic resin hinge portion 2 having a size equal to or greater than torr, and the hinge portion 2 is also provided.
A flat plate 3 made of synthetic resin was integrally connected to both left and right sides of the flat plate 3, and a plurality of holes 5 were formed in the flat plate 3. To finish the corners with sharp edges, turn the folds 4 of the hinge 2 into corners.
The left and right flat plates 3 are attached to the wall surfaces on the respective sides by applying the edges to the edges. Since the fold line 4 of the hinge part 2 just hits the tip of the corner part and the front surface side is bent in a chevron shape, the corner part with sharp corners can be finished. Further, for finishing the rounded corner portion, the hinge portion 2 is applied to the curved surface of the corner portion so as not to be bent in a chevron shape, and both flat plates are attached to the wall surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner material used for attaching to a corner portion of a wall surface of a building and finishing this portion to a flat surface having no unevenness.

[0002]

[Prior art]

 In recent years, wall surfaces of buildings are often constructed with wall covering materials such as wallpaper, cloth, and synthetic resin cloth. When attaching this kind of wall covering, it is necessary to finish the base surface to a flat surface without unevenness in order to obtain a beautiful finish, but as a wall material there are many uneven gypsum boards and Since plywood is often used, it was extremely difficult to finish the corners and corners in particular.

In order to finish the projecting corner of the wall surface of the building flatly, 1 mm thickness is applied to both left and right sides in the longitudinal direction of the hinge part made of a soft synthetic resin having a thickness of 1 mm or less and a width of 2 mm or less. -A corner material has been developed in which a flat plate made of a hard synthetic resin having a thickness of less than or equal to Torr is integrally connected, and a suitable number of holes are formed in the flat plate (Actual Publication No. 62-40030). . In this corner material, the hinge part is applied to the corner part of the building, this part is bent at a right angle, and the flat plates on both the left and right sides are respectively attached to the wall surface with an adhesive, whereby the corner part is formed. The wall of the part is flattened and the edge of the corner is sharp, so the width of the hinge part is 2 mm or less. In addition, it is said that this corner material can be used by turning the inside and outside of the building so that the outside corner portion and the inside corner portion of the building can be constructed.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional corner material is convenient because it can easily flatten the underlying surface with a large number of irregularities at the projected corners, but it is mainly intended for corners with sharp edges. Therefore, there is a problem that the rounded corner portion cannot be finished. The corners of a typical building are not only sharp but often rounded depending on the design, so one type of corner material will round the corners. It would be even more convenient if there were a corner material that could be similarly easily flattened. Therefore, the present invention provides a corner material capable of pre-finishing a cornered corner portion and a rounded corner portion with one kind of corner material. Is the subject.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention adopts the following configuration. That is, the corner material according to the present invention forms a fold along the longitudinal direction in the central portion in the width direction of a synthetic resin hinge portion having a thickness of 1 mm or less and a width of 2 mm or more. At the same time, a flat plate made of synthetic resin is integrally connected to both left and right sides of the hinge portion, and a plurality of holes are formed in the flat plate.

[0006]

[Action]

 To finish the corners with sharp edges, place the folds of the hinges on the edges of the corners, and use the left and right flat plates bent at right angles to the wall surface on each side. Paste it on. Since the fold line of the hinge part just hits the tip of the corner part and the front side is bent in a mountain shape, the corner part with sharp corners can be finished. To finish the rounded corner, apply the flat plates to the wall surface by applying the hinge to the curved surface of the corner so that the hinge is not bent into a chevron. Then, since the wide hinge part is curved along the curved surface of the corner part, it is possible to finish the rounded corner part.

[0007]

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail. This corner material 1 is formed into a strip shape as a whole, and is handled in a state of being rolled into a roll shape, and is cut into required lengths for use. A hinge portion 2 made of soft synthetic resin having high flexibility is provided in the central portion, and flat plates 3 made of hard synthetic resin are integrally connected to both left and right sides in the longitudinal direction. The thickness of the hinge part 2 is less than 1 mm and its width is larger than 2 mm. If the width of the hinge part 2 is 2 mm or less, it cannot be applied to a rounded corner part well, and if it is too wide, it is difficult to obtain a beautiful finish. Therefore, it is preferable that the width is about 3 mm or more and about 4 mm or less.

A fold line 4 is formed along the longitudinal direction at the left and right center of the hinge part 2. This fold is especially easy to fold in the hinge.

The flat plates 3 and 3 are integrally formed with the hinge portion 2, and the thickness thereof is slightly thicker than that of the hinge portion. A plurality of holes 5, ... Are regularly formed near the outer edge of the flat plate 3 along the longitudinal direction. The width of the flat plate 3 is 20 to 30 mm and the diameter of the holes 5 is 3 to 5 mm, but these dimensions may be practically convenient.

An adhesive layer 6 coated with a pressure-sensitive adhesive is provided on the lower surface side of the flat plate 3 of the corner material, and a cover paper 7 for protecting the adhesive layer is placed on the adhesive layer 6. However, these are not indispensable and the adhesive layer is not provided when the bottom side is used up.

When the corners of a building are flattened by using this corner material, the covering paper covering the adhesive layer is peeled off to expose the adhesive layer, and as shown in FIG. The portion 2 is applied to the top of the corner portion 9 and the flat plates 3 are attached to the wall surface with an adhesive. If the corner material is not provided with an adhesive layer in advance, apply the adhesive to the lower surface side of the flat plates 3 and 3 and stick it. In this case, in the case of a cornered corner, bend the fold 4 of the hinge part by applying it to the edge part, and in the case of a rounded corner, extend the fold to open the hinge part. Apply to the corner section.

Thereafter, the stepped portion formed between the outer edge portion of the flat plate and the base is leveled with putty 8 or the like, and the wall layer material 10 such as wallpaper, cloth, vinyl cloth or the like is attached thereto with an adhesive. . Since this putty or adhesive adheres to the base through the holes 5 of the flat plate 3, the adhesion strength of the corner material is improved. In the figure, 11 is a plate material such as a gypsum board and plywood, and 12 is a field material.

[0013]

[Effect of device]

 As is apparent from the above description, in the corner material 1 according to the present invention, the hinge portion which is bent at the corner portion is formed wide, and the center portion thereof is provided with the fold line along the longitudinal direction. Therefore, it is possible to use it for both corners with rounded corners and rounded corners. This corner material makes it possible to easily flatten the corners of the walls of the building, etc., thus making it possible to make the finish of the walls and the like beautiful.
