Description

【０００１】
【発明の属する技術分野】
本発明は、建物の出隅部分に使用されるコーナー部材の製造方法に関するものである。
【０００２】
【従来の技術】
図４は従来のコーナー部材の一例を示す平面図である。
【０００３】
無機質板材で外壁を構築する場合には、外壁の出隅部分でいずれか一方の無機質板材の端面が露出して見栄えが悪くなる事態を避けるため、断面Ｌ字状のコーナー部材を出隅部分に施工することが多い。
【０００４】
このコーナー部材としては、従来、図４に示すように、２枚の板材２、３の端部を裏面から表面にかけて斜めに切削し、これら板材２、３の切削面２ｄ、３ｄ同士を接着剤５で接着して断面Ｌ字状にしたコーナー部材１が広く使用されていた。
【０００５】
【発明が解決しようとする課題】
しかし、このコーナー部材１では、図４に示すように、板材２、３を接着する際に用いる接着剤５が表側に食み出し、板材２、３の化粧面を汚す恐れがある。そのため、多大な手間をかけて板材２、３の化粧面を補修する必要があるばかりでなく、その補修のときに板材２、３の化粧面を傷つけてしまうことも多いという不都合があった。
【０００６】
本発明は、上記事情に鑑み、板材の化粧面の補修が不要であり、従って補修によって板材の化粧面を傷つけることがないコーナー部材の製造方法を提供することを目的とする。
【０００７】
【課題を解決するための手段】
すなわち本発明は、２枚の板材（２、３）がＬ字断面状に接着されたコーナー部材（１）の製造方法であって、一方の板材（２）の端部を裏面から端面（２ｃ）にかけてその端面の一部が残るように斜めに切削すると共に、他方の板材（３）の端部を裏面から端面（３ｃ）にかけてその端面の一部が残るように斜めに切削する第１工程と、これら板材の切削面（２ｄ、３ｄ）同士を接着剤（５）で接着して当該板材の端面からなるＶ溝（６）を形成するとともに当該Ｖ溝（６）に前記切削面（２ｄ、３ｄ）から食み出した余分な前記接着剤を溜める第２工程と、前記接着剤が硬化した後、これら板材の切削面から食み出して硬化した状態の接着剤を取り除く形で隅角部（１ａ）を切削する第３工程とから構成される。
【０００８】
なお、括弧内の番号等は図面における対応する要素を表わす便宜的なものであり、従って本発明は図面上の記載に限定拘束されるものではない。このことは「特許請求の範囲」の欄についても同様である。
【０００９】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。
図１は本発明によるコーナー部材の製造方法の第１工程を示す平面図、
図２は本発明によるコーナー部材の製造方法の第２工程を示す平面図、
図３は本発明によるコーナー部材の製造方法の第３工程を示す平面図である。
【００１０】
本発明によるコーナー部材の製造方法は次の手順による。
【００１１】
まず、図１に示すように、基板２ａの表側に化粧層２ｂを具備した平板状の板材２の端部を裏面から端面２ｃにかけて所定の傾斜角α（例えば、α＝４５°）で斜めに切削する。この際、板材２の端面２ｃの一部が残るようにする（切削後の端面２ｃの幅は２〜５mm程度が好ましい）。同様に、基板３ａの表側に化粧層３ｂを具備した平板状の板材３の端部を裏面から端面３ｃにかけて同じ傾斜角αで斜めに切削する。この際、板材３の端面３ｃの一部が残るようにする（切削後の端面３ｃの幅は２〜５mm程度が好ましい）。
【００１２】
次いで、図２に示すように、板材２の切削面２ｄまたは板材３の切削面３ｄに接着剤５を塗布した後、これら板材２、３の切削面２ｄ、３ｄ同士を接着する。すると、所定の挟角β（＝１８０°−２α）を有するＬ字断面状になると共に、板材２、３の切削面２ｄ、３ｄの図２上側には端面２ｃ、３ｃからなるＶ溝６が形成される。また、板材２、３の切削面２ｄ、３ｄから余分な接着剤５が食み出すが、この余分な接着剤５はＶ溝６に溜まるので、板材２、３の化粧層２ｂ、３ｂが接着剤５で汚れることはない。
【００１３】
この状態で接着剤５が硬化するまで養生し、接着剤５が硬化したところで、図３に示すように、板材２、３の切削面２ｄ、３ｄから食み出してＶ溝６内で硬化した状態の接着剤５を取り除く形で、かつ板材２、３の切削面２ｄ、３ｄに対して切削面が直交するように隅角部１ａを平坦に切削する。すると、面取り加工された隅角部１ａを有するコーナー部材１が出来上がるが、板材２、３の化粧面（即ち、化粧層２ｂ、３ｂの表面）は接着剤５で汚れていないので、その補修が不要となり、補修によって板材２、３の化粧面を傷つけてしまうこともあり得ない。
【００１４】
【発明の効果】
以上説明したように本発明によれば、２枚の板材２、３がＬ字断面状に接着されたコーナー部材１の製造方法であって、一方の板材２の端部を裏面から端面２ｃにかけてその端面２ｃの一部が残るように斜めに切削すると共に、他方の板材３の端部を裏面から端面３ｃにかけてその端面３ｃの一部が残るように斜めに切削する第１工程と、これら板材２、３の切削面２ｄ、３ｄ同士を接着剤５で接着して当該板材２、３の端面２ｃ、３ｃからなるＶ溝６を形成するとともに当該Ｖ溝６に切削面２ｄ、３ｄから食み出した余分な前記接着剤を溜める第２工程と、前記接着剤５が硬化した後、これら板材２、３の切削面２ｄ、３ｄから食み出して硬化した状態の接着剤５を取り除く形で隅角部１ａを切削する第３工程とから構成したので、第２工程で板材２、３の切削面２ｄ、３ｄから食み出した余分な接着剤５はＶ溝６に溜まったまま硬化し、しかもその接着剤５は第３工程で取り除かれるため、板材２、３の化粧層２ｂ、３ｂが接着剤５で汚れる事態を回避することができることから、板材２、３の化粧面の補修が不要であり、従って補修によって板材２、３の化粧面を傷つけることがないコーナー部材の製造方法を提供することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a method of manufacturing a corner member used for a corner portion of a building.
[0002]
[Prior art]
FIG. 4 is a plan view showing an example of a conventional corner member.
[0003]
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 protruding corner portion of the outer wall and the appearance looks worse, a corner member having an L-shaped cross section is used as the protruding corner portion. Often constructed.
[0004]
As the corner member, conventionally, as shown in FIG. 4, the end portions of the two plate members 2 and 3 are cut obliquely from the back surface to the front surface, and the cutting surfaces 2d and 3d of the plate members 2 and 3 are adhesives. The corner member 1 which is bonded at 5 to have an L-shaped cross section has been widely used.
[0005]
[Problems to be solved by the invention]
However, in this corner member 1, as shown in FIG. 4, there is a possibility that the adhesive 5 used when bonding the plate members 2 and 3 sticks out to the front side and stains the decorative surface of the plate members 2 and 3. For this reason, it is not only necessary to repair the decorative surfaces of the plate members 2 and 3 with great effort, but there is also a disadvantage that the decorative surfaces of the plate members 2 and 3 are often damaged during the repair.
[0006]
In view of the above circumstances, an object of the present invention is to provide a method for manufacturing a corner member that 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]
[Means for Solving the Problems]
That is, the present invention is a method of manufacturing a corner member (1) in which two plate members (2, 3) are bonded in an L-shaped cross section, and the end portion of one plate member (2) is changed from the back surface to the end surface (2c). The first step of cutting obliquely so that a part of the end surface remains over the surface of the other plate material and obliquely cutting so that a part of the end surface remains from the back surface to the end surface (3c). Then, the cutting surfaces (2d, 3d) of these plate materials are bonded to each other with an adhesive (5) to form a V groove (6) composed of an end surface of the plate material, and the cutting surface (2d) is formed in the V groove (6). 3d), the second step of collecting the excess adhesive, and after the adhesive has hardened, the corners are removed from the cut surface of the plate material by removing the cured adhesive. And a third step of cutting the part (1a).

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing a first step of a method of manufacturing a corner member according to the present invention,
FIG. 2 is a plan view showing a second step of the corner member manufacturing method according to the present invention,
FIG. 3 is a plan view showing a third step of the corner member manufacturing method according to the present invention.
[0010]
The manufacturing method of the corner member by this invention is based on the following procedure.
[0011]
First, as shown in FIG. 1, the end portion of the flat plate material 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. To cut. At this time, a part of the end surface 2c of the plate member 2 is left (the width of the end surface 2c after cutting is preferably about 2 to 5 mm). Similarly, the end of the flat plate material 3 having the decorative layer 3b on the front side of the substrate 3a is cut obliquely at the same inclination angle α from the back surface to the end surface 3c. At this time, a part of the end surface 3c of the plate material 3 is left (the width of the end surface 3c after cutting is preferably about 2 to 5 mm).
[0012]
Next, as shown in FIG. 2, after the adhesive 5 is applied to the cutting surface 2 d of the plate material 2 or the cutting surface 3 d of the plate material 3, the cutting surfaces 2 d and 3 d of these plate materials 2 and 3 are bonded to each other. As a result, an L-shaped cross section having a predetermined included angle β (= 180 ° −2α) is formed, and a V-groove 6 including end surfaces 2c and 3c is formed on the cutting surfaces 2d and 3d of the plate members 2 and 3 in FIG. It is formed. Further, excess adhesive 5 protrudes from the cutting surfaces 2d and 3d of the plate materials 2 and 3, but since this excess adhesive 5 accumulates in the V-groove 6, the decorative layers 2b and 3b of the plate materials 2 and 3 are bonded. The agent 5 does not get dirty.
[0013]
In this state, the adhesive 5 was cured until it hardened, and when the adhesive 5 was hardened, it protruded from the cutting surfaces 2d and 3d of the plate members 2 and 3 and hardened in the V-groove 6 as shown in FIG. The corner 1a is cut flat so that the adhesive 5 in the state is removed and the cutting surfaces are perpendicular to the cutting surfaces 2d and 3d of the plate members 2 and 3. Then, the corner member 1 having the chamfered corner portion 1a is completed, but the decorative surfaces of the plate members 2 and 3 (that is, the surfaces of the decorative layers 2b and 3b) are not stained with the adhesive 5, so that the repair is possible. It becomes unnecessary, and the decorative surface of the plate materials 2 and 3 cannot be damaged by the repair.
[0014]
【The invention's effect】
As described above, according to the present invention, a method of manufacturing a corner member 1 in which two plate members 2 and 3 are bonded in an L-shaped cross section, the end of one plate member 2 extending from the back surface to the end surface 2c. A first step of cutting diagonally so that a part of the end surface 2c remains, and cutting diagonally so that a part of the end surface 3c remains from the back surface to the end surface 3c from the back surface to the end surface 3c, and these plate materials The cutting surfaces 2d and 3d of 2 and 3 are bonded to each other with an adhesive 5 to form a V-groove 6 composed of the end surfaces 2c and 3c of the plate members 2 and 3, and the V-groove 6 eats from the cutting surfaces 2d and 3d. In the form of removing the adhesive 5 in the second step of storing the excess adhesive that has been taken out, and after the adhesive 5 is cured, the adhesive 5 that protrudes from the cutting surfaces 2d and 3d of the plate members 2 and 3 and is cured. Since it is configured from the third step of cutting the corner 1a, the second work The excess adhesive 5 protruding from the cutting surfaces 2d and 3d of the plate materials 2 and 3 is cured while remaining in the V-groove 6, and the adhesive 5 is removed in the third step. Since it is possible to avoid the situation where the decorative layers 2b and 3b of the plate are soiled with the adhesive 5, it is not necessary to repair the decorative surfaces of the plate materials 2 and 3, so that the decorative surfaces of the plate materials 2 and 3 are not damaged by the repair. It becomes possible to provide the manufacturing method of a corner member.
