Abstract

PROBLEM TO BE SOLVED: To dissolve the inconvenience in which the decorative face of a plate becoming dirty by protruded adhesive must be repaired without injuring it, when two plates are let adhere into an L-shaped section so as to manufacture a corner member. SOLUTION: The end part of one plate 2 is obliquely cut extending from the back to the end face 2c so as to leave a part of the end face 2c, and the end part of the other plate 3 is obliquely cut extending from the back to the end face 3c so as to leave a part of the end face 3c. Next, the cut faces 2d, 3d of the plates 2, 3 are let adhere with each other by adhesive 5 so as to form a V-groove 6 formed out of the end faces 2c, 3c of the plates 2, 3. After hardening the adhesive 5, a corner angle part 1a is cut so that the adhesive 5 protruded from the cut faces 2d, 3d of the plates 2, 3 and hardened is removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a corner member used in a corner portion of a building.

[0002]

2. Description of the Related Art FIG. 4 is a plan view showing an example of a conventional corner member.

When constructing an outer wall with an inorganic plate material, in order to avoid a situation in which the end face of one of the inorganic plate materials is exposed at the projected corner portion of the outer wall and the appearance is deteriorated, a corner member having an L-shaped cross section is provided. Often installed in the corners.

As this corner member, conventionally, as shown in FIG. 4, the end portions of two plate materials 2 and 3 are obliquely cut from the back surface to the front surface, and the cut surfaces 2d of these plate materials 2 and 3 are
The corner member 1 having an L-shaped cross section formed by adhering 3d to each other with an adhesive 5 has been widely used.

[0005]

However, in this corner member 1, as shown in FIG. 4, the adhesive 5 used for adhering the plate members 2 and 3 squeezes out to the front side, so that the makeup of the plate members 2 and 3 is improved. It may stain the surface. Therefore, there is a disadvantage that not only it is necessary to repair the decorative surfaces of the plate materials 2 and 3 with great effort, but also the decorative surfaces of the plate materials 2 and 3 are often damaged during the repair.

In view of the above circumstances, it is an object of the present invention to provide a method for manufacturing a corner member which does not require repair of the decorative surface of the plate material and therefore does not damage the decorative surface of the plate material.

[0007]

That is, the present invention is a method for manufacturing a corner member (1) in which two plate members (2, 3) are bonded to each other in an L-shaped cross section, and one plate member (2) is provided. The end of the plate material is cut diagonally from the back surface to the end surface (2c) so that a part of the end surface remains, and the end of the other plate material (3) partially remains from the back surface to the end surface (3c). And the second step of adhering the cut surfaces (2d, 3d) of the plate materials to each other with the adhesive (5) to form the V groove (6) formed of the end surface of the plate material. After the adhesive is hardened, the corner portion (1a) is formed so as to be extruded from the cutting surface of these plate materials to remove the hardened adhesive.
And a third step of cutting.

It is to be noted that the numbers in parentheses are for convenience showing the corresponding elements in the drawings, and therefore, the present invention is not limited to the description on the drawings. The same applies to the column of “Claims”.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view showing a first step of a method for manufacturing a corner member according to the present invention, FIG. 2 is a plan view showing a second step of a method for manufacturing a corner member according to the present invention, FIG.
FIG. 6A is a plan view showing a third step of the method for manufacturing a corner member according to the present invention.

The manufacturing method of the corner member according to the present invention is as follows.

First, as shown in FIG. 1, the end portion of the flat plate-shaped plate member 2 having the decorative layer 2b on the front side of the substrate 2a is inclined at a predetermined inclination angle α (for example, α = 45) from the back surface to the end surface 2c.
Cut diagonally at (°). At this time, a part of the end surface 2c of the plate material 2 is left (the width of the end surface 2c after cutting is 2 to 5 mm).
Degree is preferred). Similarly, the decorative layer 3 is formed on the front side of the substrate 3a.
From the back surface to the end surface 3c
Cutting diagonally with the same inclination angle α. At this time, a part of the end face 3c of the plate material 3 is left (the end face 3 after cutting).
The width of c is preferably about 2 to 5 mm).

Then, as shown in FIG. 2, after the adhesive 5 is applied to the cutting surface 2d of the plate material 2 or the cutting surface 3d of the plate material 3, the cutting surfaces 2d and 3d of these plate materials 2 and 3 are adhered to each other. Then, an L-shaped cross section having a predetermined included angle β (= 180 ° -2α) is formed, and the cutting surfaces 2d of the plate members 2 and 3 are
On the upper side in FIG. 2 of 3d, a V-groove 6 composed of end faces 2c and 3c is formed. Further, the excess adhesive 5 oozes out from the cut surfaces 2d and 3d of the plate materials 2 and 3, but since the excess adhesive 5 accumulates in the V groove 6, the decorative layers 2b and 3b of the plate materials 2 and 3 are bonded. It does not get soiled with Agent 5.

In this state, curing is carried out until the adhesive 5 is hardened, and when the adhesive 5 is hardened, as shown in FIG.
The cutting surface 2d, 3d of the plate materials 2, 3 is protruded from the cutting surface 2d, 3d to remove the cured adhesive 5 in the V groove 6, and the cutting surface is orthogonal to the cutting surfaces 2d, 3d of the plate materials 2, 3. The corner portion 1a is cut flat so as to do so. Then, the corner member 1 having the chamfered corner portion 1a is completed, but since the decorative surfaces of the plate materials 2 and 3 (that is, the surfaces of the decorative layers 2b and 3b) are not soiled with the adhesive 5, the repair thereof is required. It becomes unnecessary, and the decorative surfaces of the plate materials 2 and 3 cannot be damaged by the repair.

[0014]

As described above, according to the present invention, 2
A method for manufacturing a corner member 1 in which two plate members 2 and 3 are bonded to each other in an L-shaped cross-section, wherein one end of one plate member 2 is slanted from the back surface to the end surface 2c so that a part of the end surface 2c remains. The first step of cutting the other plate member 3 obliquely from the back surface to the end face 3c so that a part of the end face 3c remains, and the cutting surfaces 2d, 3 of the plate members 2, 3
The end surfaces 2 of the plate members 2 and 3 are adhered to each other with an adhesive 5
c), a second step of forming a V groove 6 composed of 3c, and after the adhesive 5 is hardened, a cutting surface 2d of these plate materials 2 and 3,
Since it is composed of a third step of cutting the corner portion 1a so as to remove the cured adhesive 5 from the cutting surface 2d, 3d of the plate materials 2, 3 in the second step. The extra adhesive 5 that has come out is cured while remaining in the V groove 6,
Moreover, since the adhesive 5 is removed in the third step, it is possible to avoid the situation where the decorative layers 2b and 3b of the plate materials 2 and 3 are soiled with the adhesive 5, so that it is not necessary to repair the decorative surface of the plate materials 2 and 3. Therefore, it is possible to provide a method for manufacturing a corner member that does not damage the decorative surfaces of the plate materials 2 and 3 by the repair.
