Description

The present invention relates to a corner panel.

The surface of the protruding corner inside the building is finished by attaching a resin or metal corner material. When a resin corner material is applied, there is a problem in fire resistance. On the other hand, when a metal corner material is applied, it has excellent heat transfer properties, so when a fire breaks out indoors, there is a risk of ignition of the pillars arranged inside the wall. There is a problem that dew condensation is likely to occur.

In order to solve the problems of resin and metal corner materials, a corner board having a gypsum board and a reinforcing member has been proposed. More specifically, the first gypsum board core material that faces one side surface of the pillar on the back surface and the second gypsum board core that faces the other side surface adjacent to one side surface of the pillar on the back surface. The material part, the paper member arranged so as to cover the surface of the first gypsum board core material part and the surface of the second gypsum board core material part, and the first gypsum board core material part and the second gypsum board core material part. It is a corner board having a reinforcing member arranged adjacent to the paper member and adjacent to the back surface of the paper member. The corner board is arranged so as to cover the corners formed by one side surface and the other side surface of the pillar (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2015-151743

However, in the corner board described in Patent Document 1, since the reinforcing member is in close contact with the side surface of the corner portion of the protruding corner pillar and is attached in surface contact, the protruding corner pillar has a right-angled corner portion with high accuracy. If this is not done, the first gypsum board core and the second gypsum board core cannot be brought into close contact with the side surface of the protruding corner column. Then, when the gypsum board core material and the side surface of the projected corner pillar are not in close contact with each other, the corner board is centered on the reinforcing member when the core material of each gypsum board is attached to the side surface of the projected corner pillar with screws or the like. As a result, it will be distorted to the side of the protruding corner pillar or the side opposite to the protruding corner pillar. When the corner board is distorted around the reinforcing member in this way, the joint between the gypsum board core material and the reinforcing member, which is a weak part of the corner board, cannot withstand the stress caused by the strain. There is a risk of damage.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a corner panel having excellent fire resistance and having no risk of damage when attached to an indoor protruding corner skeleton such as a protruding corner pillar.

In order to achieve the above object, one aspect of the corner panel according to the present invention is

[Embodiment]
<Corner panel>
First, an example of the corner panel according to the embodiment will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a perspective view showing an example of the corner panel according to the embodiment, and FIG. 2 is a cross-sectional view of the corner panel according to the embodiment, which is a view taken along the line II-II of FIG. be.

The corner panel 100 has a corner base material 10, a first face material 20, and a second face material 30, and has an outer surface 12 of the corner base material 10, an outer surface 22 of the first face material 20, and a second face material. The outer surface 32 of 30 is integrally covered with an outer surface side paper member 40 made of base paper for gypsum board or the like. Further, the inner surface 23 of the first surface material 20 and the inner surface 33 of the second surface material 30 are covered with a first inner surface side paper member 50A and a second inner surface side paper member 50B made of base paper for gypsum board or the like, respectively.

The corner panel 100 is an L-shaped panel in a plan view in which the first face material 20 and the second face material 30 are orthogonal to each other, for example, with the corner base material 10 as the center. In the corner panel 100 of the illustrated example, the first face material 20 and the second face material 30 are orthogonal to each other, but the relative angle between the first face material 20 and the second face material 30 is the corner panel 100. The angle is set according to the angle of the two sides of the projected corner skeleton to which the is attached.

The length of the corner panel 100 in the longitudinal direction is, for example, about 900 mm to 3000 mm, but can be any length. The plate thickness of the first face material 20 and the second face material 30 is, for example, about 6 mm to 30 mm, and the length of the first face material 20 and the second face material 30 in the width direction is about 20 mm to 100 mm. be.

The corner base material 10 is a first end portion 13 connecting the inner surface 11 facing the protruding corner pillar 200 (see FIG. 3), the outer surface 12 on the opposite side (indoor side) of the inner surface 11, and the inner surface 11 and the outer surface 12. A first end surface 13a and a second end surface 14a of the second end portion 14 are provided. On the inner surface 11, a recess 16 recessed from the boundary 151 of the first end portion 13 and the boundary 152 of the second end portion 14 toward the inside of the corner base material 10 is formed.

Further, the corner base material 10 has two corners at both ends of the first end surface 13a and two corners at both ends of the second end surface 14a, for a total of four corners 17. Have. More specifically, the first corner portion 171 on the protruding corner skeleton side of the first end surface 13a, the second corner portion 172 on the opposite side (indoor side) of the protruding corner skeleton of the first end surface 13a, and the second It has a third corner portion 173 on the protruding corner skeleton side of the end surface 14a and a fourth corner portion 174 on the opposite side (indoor side) of the protruding corner skeleton of the second end surface 14a. All of the four corner portions 17 (171, 172, 173, 174) are subjected to R chamfering. The type of chamfering is not limited to the R chamfering, and may be various chamfering such as thread chamfering and square chamfering.

Since all the corner portions 17 of the corner base material 10 are chamfered, even if the first face material 20 and the second face material 30 are bent with respect to the corner base material 10, the corner base material 10 is used. It is suppressed that the corners of the 10 are in strong contact with the first face material 20 and the second face material 30. Therefore, a strong pressing force is applied from the first surface material 20 and the second surface material 30 to the corner portion of the corner base material 10, and the problem that the corner portion is damaged by this pressing force is suppressed.

Here, at the boundary 15 (151), as shown in FIG. 2, for example, an end portion P1 in which the first end surface 13a is separated from the third end surface 21 and a connecting portion P1'of the first end surface 13 and the recess 16 are formed. The range between and (the range of the width of the first end portion 13) is included. Similarly, at the boundary 15 (152), a range (second) between the end portion P3 in which the second end surface 14a is separated from the fourth end surface 31 and the connecting portion P2'between the second end surface 14 and the recess 16. The width range of the end 14) is included. The tops P2 and P4 of the chamfered corners 171 (173) in these ranges are also included.

As shown in FIG. 2, the boundary 15 (151,152) with the first inner surface side paper member 50A and the second inner surface side paper member 50B covering the inner surface 23 of the first surface material 20 and the inner surface 33 of the second surface material 30. ) Is not flush with the end portion P1 (P3), the connecting portion P1'(P3'), and the top portion P2 (P4), and the boundary 15 (151, 152) is on the inner side of the corner base material 10. It is in a depressed position. Therefore, as will be described in detail below, when the corner panel 100 is attached to the protruding corner pillar 200 (see FIG. 3), the boundary 15 (151, 152) is eliminated from the surface contact with the protruding corner pillar 200. Even if the boundary 15 (151, 152) comes into contact with the protruding corner pillar 200, the top P2 (P4) included in the boundary 15 (151, 152) makes a point contact or a line contact with the protruding corner pillar 200. It is suppressed and at least does not come into surface contact with the protruding corner pillar 200. Therefore, unlike the corner board described in Patent Document 1 described above, the problem that occurs when the reinforcing member of the corner board comes into surface contact with the side surface of the corner portion of the protruding corner column does not occur in the corner panel 100.

The outer surface 12 of the corner base material 10 has a central arc surface 12a and two flat surfaces 12b and 12c between the arc surface 12a and the first end surface 13 and the second end surface 14.

As the material for forming the corner base material 10, an inorganic material is preferable from the viewpoint of excellent fire resistance. Examples of the inorganic material include materials containing cement, siliceous powder, aggregate, and fiber as main components. When cement, siliceous powder, aggregate and fiber are the main components, the ratio of the total mass of cement, siliceous powder, aggregate and fiber to the total mass of the material is, for example, 95% by mass or more. Means.

On the other hand, the first surface material 20 covers the third end surface 21 connected to the first end surface 13a of the corner base material 10, the outer surface 22 coated on the outer surface side paper member 40, and the first inner surface side paper member 50A. It has an inner surface 23 to be formed. Further, the second face material 30 covers the fourth end surface 31 connected to the second end surface 14a of the corner base material 10, the outer surface 32 covered with the outer surface side paper member 40, and the second inner surface side paper member 50B. It has an inner surface 33 to be formed.

A gypsum-based face material is applied to the first face material 20 and the second face material 30. Examples of gypsum-based face materials include gypsum boards such as ordinary gypsum board, reinforced gypsum board, and ordinary hard gypsum board, glass mat gypsum board, glass fiber non-woven gypsum board, and slag gypsum board. The gypsum board referred to here is a board in which at least both sides of the gypsum core are covered with a base paper for gypsum board.

From the viewpoint of facilitating wallpaper finishing and paint finishing, which are the most common interior finishes, it is preferable that the gypsum-based face material is covered with a base paper for gypsum board as shown in the illustrated example. Specifically, ordinary gypsum board, reinforced gypsum board, and ordinary hard gypsum board, which are covered with a base paper for gypsum board, are particularly preferable. Further, the first face material 20 and the second face material 30 may be formed of the same type of gypsum-based face material, or may be formed of different types of gypsum-based face material. Further, a gypsum-based face material other than the gypsum board, which is a face material other than the gypsum board, may be applied to the outer surface 22 and the second face material 30 of the first face material 20. When gypsum board is used as the gypsum-based face material, the gypsum core of the gypsum board becomes the first face material 20 and the second face material 30.

Since the corner panel 100 has the outer surface side paper member 40, the outer surface 12 of the corner base material 10, the outer surface 22 of the first surface material 20, and the outer surface 32 of the second surface material 30 come into contact with other members. Shaving is suppressed. Further, when a cloth (wallpaper) or the like is attached to the indoor side of the corner panel 100, the adhesiveness with the cloth is improved, and the handleability of the corner panel 100 is also improved.

Further, it is preferable that both the contact surfaces of the first end surface 13a and the third end surface 21 and the contact surfaces of both the second end surface 14a and the fourth end surface 31 are connected by an adhesive. Examples of this adhesive include organic adhesives (vinyl acetate-based, acrylic-based, isocyanate-based, etc.) and inorganic adhesives (inorganic silicate-based, etc.).

<Structure of the protruding corner>
Next, with reference to FIG. 3, the structure of the protruding corner formed by attaching the corner panel to the protruding corner skeleton will be described. Here, FIG. 3 is a cross-sectional view showing the structure of the protruding corner formed by attaching the corner panel according to the embodiment to the protruding corner pillar.

The projected corner pillar 200 (an example of the projected corner skeleton) in the illustrated example has, for example, two planes 201 and 202 that project into the room in a rectangular shape in a plan view and are orthogonal to each other through the corner portion 203. The protruding corner pillar 200 includes, for example, a core material of a wooden pillar, a material to which a face material such as a gypsum-based face material is attached to the surface of the core material of the pillar, and the like. The protruding corner skeleton is not limited to the protruding corner pillar 200 of the illustrated example, and there are other openings such as a beam, a duct space portion, a sleeve wall, and a wall.

With respect to the two planes 201 and 202, the first inner surface side paper member 50A attached to the inner surface 23 of the first surface material 20 and the second inner surface side paper member attached to the inner surface 33 of the second surface material 30. The corner panel 100 is arranged so that the 50Bs come into contact with each other. Then, the first face material 20 and the second face material 30 are fixed to the protruding corner pillar 200 by fixing means 60 such as screws, respectively, so that the protruding corner 300 composed of the protruding corner pillar 200 and the corner panel 100 is formed. Will be done.

In a state where the corner panel 100 is attached to the protruding corner pillar 200, the corner portion 203 of the protruding corner pillar 200 is housed in the recess 16 of the corner base material 10. Further, the corner base material 10 does not come into contact with the two planes 201 and 202, including the corner portion 203 of the protruding corner pillar 200. This is because, as already explained, the corner base material 10 is recessed on the inner surface 11 from the boundary 151 of the first end portion 13 and the boundary 152 of the second end portion 14 toward the inside of the corner base material 10. This is because it has a concave groove 16. The end portions P1, P3, the connecting portions P1', P2', the top portions P2, and P4 included in the boundary 15 (151, 152) are the inner surface 23 of the first face material 20 and the inner surface of the second face material 30. This is because the position is lower than the first inner surface side paper member 50A and the second inner surface side paper member 50B that cover 33.

In the illustrated example, the thickness of the first end portion 13 (the thickness at the position of the top portion P2 which is the maximum value) is thinner than the thickness of the first face material 20, and the thickness of the second end portion 14 (the maximum value). The thickness at the position of the top portion P4) is thinner than the thickness of the second face material 30, but the thickness of the first end portion 13 is equal to the thickness of the first face material 20 and the thickness of the second end portion 14. May be equal to the thickness of the second face material 30. Further, as shown in the illustrated example, when the first inner surface side paper member 50A and the second inner surface side paper member 50B are provided, the thickness of the first end portion 13 is the thickness of the first surface material 20 and the first inner surface side paper. Is it equal to or thinner than the sum of the thicknesses of the members 50A, and the thickness of the second end portion 14 is equal to or less than the sum of the thicknesses of the second face member 30 and the thickness of the second inner surface side paper member 50B? It may be in a thin form. The thickness of the first inner surface side paper member 50A (second inner surface side paper member 50B) changes by being pressed by the protruding corner pillar 200 in addition to the initial thickness of the first inner surface side paper member 50A and the like. The thickness of the paper is also included.

In this way, the thickness of the first end portion 13 (second end portion 14) is thinner than the thickness of the first face material 20 (second face material 30), or the first end portion 13 (second end). The thickness of the portion 14) is thinner than the sum of the thickness of the first surface material 20 (second surface material 30) and the thickness of the first inner surface side paper member 50A (second inner surface side paper member 50B), which is non-contact. It is in a state.

On the other hand, the thickness of the first end portion 13 (second end portion 14) is equal to the thickness of the first face material 20 (second face material 30), or the first end portion 13 (second end portion 14). Is equal to the sum of the thickness of the first surface material 20 (second surface material 30) and the thickness of the first inner surface side paper member 50A (second inner surface side paper member 50B), which is a state of line contact. ..

In the projected corner 300 having the corner panel 100 according to the embodiment, as the relationship between the corner base material 10 and the projected corner pillar 200, either a non-contact state or a line contact state is applied.

Here, FIG. 4 simulates a state in which the corner board (conventional corner panel) described in Patent Document 1 described above is attached to the protruding corner pillar 200 to form a protruding corner 300'. .. In FIG. 4, in the corner base material 10'forming the corner panel 100', the inner side surface 11'on the protruding corner pillar 200 side is in close contact with the side surface of the corner portion 203 of the protruding corner pillar 200 and is in surface contact with the corner base material 10'. Therefore, if the corners 203 of the protruding corner pillar 200 do not have an accurate right angle, the first face material 20 and the second face material 30 cannot be brought into close contact with the side surfaces 201 and 202 of the protruding corner pillar 200. In such a state, when the first face material 20 and the second face material 30 are attached to the side surface of the protruding corner pillar 200 with screws or the like, the corner panel 100'is centered on the corner base material 10' on the protruding corner pillar 200 side or. It will be distorted to the opposite side of the protruding corner pillar 200. When the corner panel 100'is distorted around the corner base material 10' in this way, the corner base material 10', which is a weak part of the corner panel 100', and the first face material 20 and the second face material 30' The joint with and may not be able to withstand the stress caused by the strain and may be damaged.

As shown in FIG. 3, the corner base material 10 is not in surface contact with the protruding corner pillar 200, but in a non-contact state (or in a line contact state or a point contact state (with respect to the protruding corner pillar 200). By attaching the corner panel 100 to the protruding corner pillar 200 so as to be in contact with one or more points in the vertical direction), it depends on the accuracy such as the angle of the corner portion 203 of the protruding corner pillar 200. It is possible to eliminate the damage of the corner panel 100 at the time of attachment to the protruding corner pillar 200 without having to do so.

In the illustrated example, the first inner surface side paper member 50A is attached to the inside of the first surface material 21, and the second inner surface side paper member 50B is attached to the inside of the second surface material 30. In the form in which the first inner surface side paper member 50A and the second inner surface side paper member 50B are not attached, the thickness of the corner base material 10 is equal to or relative to the thickness of the first surface material 21 and the second surface material 30. By thinning the paper, damage to the corner panel 100 can be eliminated as in the illustrated example.

<Manufacturing method of corner panel>
