【発明の属する技術分野】
本発明は、建造物の壁面を構成する板状部材の取付構造に関する。
【０００２】
【従来の技術】
近年、建造物は、カーテンウォール構法などの外壁構法を用いてガラス板等の板状部材を躯体側に支持させ、これにより外壁を構築している例が増えている。また、そのなかで板面の連続性を損なうことなく外壁の構築を可能とすべく板状部材を躯体側に支持させながら上下左右方向へと連続する同一平面を形成する、孔あき強化ガラス使用ファサード構法（別称ドットポイント構法）も多用されている。
【０００３】
この孔あき強化ガラス使用ファサード構法では、ガラス板に皿孔加工を施し、取付用金物がガラス板面から出っ張らず、平坦な面を構成するような配慮がなされている。
【０００４】
図８は、板面の連続性を損なうことなく外壁の構築を可能とした従来例の板状部材の取付構造の要部断面図である。
【０００５】
これによれば、板状部材１は室外側に皿孔部２１を有するに取付用孔２０が設けられており、これら取付用孔２０には、適宜の素材からなる介装材、例えばアルミニウム材等の金属材料や合成樹脂材料を用いて形成される環状部材３を介して板状部材取付用金物２が嵌着されている。なお、取付用孔２０に嵌着された板状部材取付用金物２は、ワッシャー材４を介在させたナット材５により板状部材に緊締螺着される。
【０００６】
このような構成からなる板状部材１と板状部材取付用金物２とは、取付用孔２０における前記皿孔部２１を室外側に位置させるとともに、室内側において板状部材１を支持機構３２により各別に枢支可能に支持させることで、複数枚の板状部材１により同一平面を連続形成することができる。
【０００７】
このように、孔あき強化ガラス使用ファサード構法においては、ガラス板面と取付用金物の表面に凸凹がなく、平坦な壁面を構成していることが意匠上優れた点としてあげられる。
【０００８】
しかし、実際は板状部材の皿孔部の加工精度のばらつきおよび取付用金物の加工精度のばらつきにより、板状部材の皿孔部に対し取付用金物が予め設計された位置、姿勢とならず、板状部材の取付用金具の室外側の頭部の面部分に凹部（例えば、図８における引っ込み部Ａ）ができたり、取付用金具の頭部が板状部材の表面から突出したりして、板状部材面と取付用金物の頭部の室外側表面に凸凹ができることがある。
【０００９】
このことは、意匠性を損なうだけでなく、板状部材面に対し板状部材取付用金物が凹となっている場合においては、環状部材の端部鋭角部分が板状部材の皿孔加工面に局所的に接するため可能性があり、板状部材が風圧力などの外力を受けたとき、集中的に応力が発生してしまうおそれがあった。
また、同様に、板状部材としてガラス板を使用した場合、ガラス板面に対し板状部材取付用金物の頭部部分が凹状となっている場合においては、板状部材取付用金物を取付用孔に装着した同ガラス板の皿孔部の加工側と取付用孔の加工を施さない別のガラス板とを、ポリビニルブチラールなどの樹脂製中間層を介し合わせガラス、すなわち複合状の板状部材とするときに、同ガラス板の皿孔部の加工側の板状部材取付用金物面と別のガラス板面との間の隙間に樹脂製中間膜が埋まりきらず、別のガラス板と取付用金物との間に気泡が残ってしまい、耐久性の劣化、意匠性を低下させる可能性があった。
【００１０】
【発明が解決しようとする課題】
本発明は、前述の課題を解決するべくなされたものであり、一側に皿孔部を有する取付用孔を施してある板状部材を用い、前記皿孔部に板状部材取付用金物（以下単に取付用金具ともいう）を装着して建造物の壁面を形成する板状部材の取付構造において、板状部材面と取付金物の室外側面とを面一とし、意匠性に優れた壁面を構成することのできる板状部材の取付構造を提供すること目的とする。
【００１１】
【課題を解決するための手段】
上記の目的を達成するために、本発明では、一側に皿孔部を有する取付用孔を施してある板状部材と、取付用孔の加工を有しない板状部材を樹脂からなる接着層を介し一体とした複合状の板状部材を用い、前記皿孔部に環状部材を介して板状部材取付用金物を装着して建造物の壁面を形成する板状部材の取付構造において、取付用孔の加工を施した板状部材と環状部材との間の皿孔部および板状部材取付用金物と環状部材との間の皿孔部の少なくとも一方に、プラスチックからなり略断面ハ字状の円環状の形状、もしくはプラスチックからなり切り込みを有す平らな円環状の形状である位置調整用スペーサーを挿入したことを特徴とする複合状の板状部材の取付構造を提供するものである。
【００１２】
【発明の実施の形態】
図１から図４は、板状部材の取付構造を示す説明図である。
図１は、板状部材の取付構造の要部断面図、図２は、板状部材の取付構造の要部の分解斜視図を示す。
【００１３】
板状部材１は、建造物の室外側に皿孔部２１を有する取付用孔２０が設けられており、この取付用孔２０には、適宜の素材からなる介装材、例えばアルミニウム材等の金属材料や合成樹脂材料を用いて形成される環状部材３を、また、皿孔部２１の板状部材１と環状部材３の間には、位置調整用スペーサー１１を介して板状部材取付用金物２が嵌着されている。なお、取付用孔２０に嵌着された板状部材取付用金物２は、取付孔２０の室内側周辺においてワッシャー材４を介在させたナット材５により板状部材１に緊締螺着される。
【００１４】
位置調整用スペーサー１１は、板状部材の皿孔部の加工精度のばらつきおよび板状部材取付用金具の加工精度のばらつきによる取付用金具の所定の設計位置、角度から若干ずれて取付用金具の室外側の頭部面が板状部材の室外側表面に対し突出したり、凹となったりして、凹凸が生ずるのを防ぎ、板状部材の室外側表面と取付用金具の室外側の頭部面とが面一となることができるように位置調整するため、すなわち板状部材取付用金物の板状部材の厚さ方向への出入り調整するためのものであり、略円環状のある程度の緩衝性を有し、かつ板状部材取付用金物２とナット材５により締め込まれ、厚さ方向に圧縮力を受けることから、ある程度硬質であり、かつ、板状部材に直接触れることから、特に板状部材１がガラス板などのときに板状部材１を傷つけない材料が要求される。このような点から位置調整用スペーサーの材料としては、プラスチックなどの樹脂材料が好ましく、耐久性の面からテフロン（商品名）などのフッ素樹脂などが好ましい。
【００１５】
位置調整用スペーサー１１の形状は、板状部材の皿孔部と取付用金具とに介装されるような形状、例えば厚さが余り厚くない略円環状が適当である。例えば、図４のように板状部材の取付用孔２０の皿孔部２１および取付用金具取付金物の形状にそった略断面ハ字状の形状をしていることが望ましいが、図５のスペーサー１２のように平らな円環状の形状であって切り込み１３を施し、板状部材の取付孔２０および取付用金具２の形状に追従する形をとってもよい。
【００１６】
位置調整用スペーサーは、上記したように板状部材の皿孔部の加工精度のばらつきおよび板状部材取付用金具の加工精度のばらつきを調整し、板状部材取付用金物の板状部材の厚さ方向への出入り調整し、板状部材の室外側面と取付用金物の室外側面とを面一できるように、挿入する位置調整用スペーサー１１の厚みの変更、あるいは位置調整用スペーサー１１の挿入枚数の変更を図り、上記板状部材面と取付用金物面の凸凹を吸収することができる。
【００１７】
このように板状部材１の取付用孔２０に嵌着されたと板状部材取付用金物２は、建造物の室内側において建造物の躯体３１に取り付けられた支持機構３２に、ワッシャー６およびナット７を介し各別に強固に枢支して支持させる。
【００１８】
図３に、本発明のガラス板からなる板状部材の取付構造を用い、支持機構３２を建造物の躯体３１に取り付けられた支持構造体３３に取り付けて壁面を構成した例の建造物の壁面の斜視図を示す。
【００１９】
図６に、板状部材の取付構造の別の例の要部断面図を示す。
この例によれば、板状部材１は建造物の室外側に皿孔部２１を有する取付用孔２０が設けられたており、この取付用孔２０には、適宜の素材からなる介装材、例えばアルミニウム材等の金属材料や合成樹脂材料を用いて形成される環状部材３を、また、皿孔部２１の板状部材１と環状部材３との間には位置調整用スペーサー１１を、環状部材３と板状部材取付用金物２の間に、もう一つの位置調整用スペーサー１１’を介して板状部材取付用金物２が嵌着されている。この位置調整用スペーサー１１’も、位置調整用スペーサー１１と同様な機能を与えるものであり、同様な材質、形状、構成をもって使用することができる。
【００２０】
なお、取付用孔２０に嵌着された板状部材取付用金物２は、取付孔２０の室内側周辺においてワッシャー材４を介在させたナット材５により板状部材１に緊締螺着される。
【００２１】
図７に、本発明の板状部材の取付構造の実施例の要部断面図を示す。この実施例によれば、ガラス板からなる複合状の板状部材１０は、孔加工部分を有しないガラス板からなる板状部材８と皿孔部の加工部分を有するガラス板からなる板状部材１とが、ポリビニルブチラールなどの樹脂からなる接着性の合せ中間膜９を介して合せ加工し、板状部材（ガラス板）８と板状部材（ガラス板）１と接着し、合せガラスとして構成されている。
【００２２】
板状部材１は、室外側に皿孔部２１を有するに取付用孔２０が設けられており、この取付用孔２０には、適宜の素材からなる介装材、例えばアルミニウム材等の金属材料や合成樹脂材料を用いて形成される環状部材３を、また、皿孔部２１の板状部材１と環状部材３との間には、位置調整用スペーサー１１を介して板状部材取付用金物２が嵌着されている。なお、取付用孔２０に嵌着された板状部材取付用金物２は、板状部材１の取付孔２０の室内側周辺においてワッシャー材４を介在させたナット材５により板状部材１に緊締螺着される。
【００２３】
このとき、位置調整用スペーサー１１は取付用孔２０の加工誤差により発生する板状部材面と取付用金物面とを面一にするために用いるものであり、挿入するスペーサー１１の厚みの変更、あるいは位置調整用スペーサー１１の挿入枚数の変更によって調整を行うことによって、板状部材面と取付用金物面の凸凹を吸収することが可能となる。
【００２４】
これによって、板状部材８と板状部材１とを接着層９を介し合わせ加工する際に、板状部材８と取付用金物２の間に気泡が残る可能性を低くし、板状部材８がガラスなどの透明材料である場合、意匠性に優れた板状部材１０を得ることが可能となる。
【００２５】
【発明の効果】
一側に皿孔部を有する取付用孔を施してある板状部材を用い、前記皿孔部に板状部材取付用金物を装着して壁面を形成する板状部材の取付構造において、板状部材と板状部材取付用金物との間の皿孔部に、樹脂材などからなる位置調整用スペーサーを挿入することによって板状部材面と取付用金物表面との出入り位置を調整することが可能となり、板状部材面と取付用金物の室外側の頭部の面とを面一とすることにより、意匠上優れ、かつ耐久性の高い板状部材取付構造を提供することができる。
【００２６】
また、板状部材と板状部材取付用金物との間の皿孔部に樹脂材などからなる位置調整用スペーサーを挿入することによって、板状部材が風圧力などの外力を受けたときに、位置調整用スペーサーが緩衝材として働き板状部材の皿孔部に発生する応力を小さくすることができる。
【００２７】
さらに、板状部材面と取付用金物の室外側の表面を面一とすることができることから、板状部材がガラス板などのとき、板状部材取付用金物を取付用孔に装着した同ガラス板の皿孔加工側と別のガラス板とをポリビニルブチラールなどの樹脂製接着性合せ中間膜を介し合わせガラスとするときに、同ガラス板の皿孔加工側の板状部材取付金物面と別のガラス板面との間に余分な空間ができず気泡などが混入しにくい耐久性の優れた板状部材の取付構造を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a plate-like member constituting a wall surface of a building.
[0002]
[Prior art]
In recent years, there are an increasing number of buildings in which an outer wall is constructed by supporting a plate-like member such as a glass plate on the housing side using an outer wall construction method such as a curtain wall construction method. In addition, the use of perforated tempered glass that forms the same plane continuous in the vertical and horizontal directions while supporting the plate-like member on the housing side so that the outer wall can be constructed without impairing the continuity of the plate surface. The facade construction method (also known as the dot point construction method) is often used.
[0003]
In this facade construction method using perforated tempered glass, consideration is given to forming a flat surface by applying a countersink to the glass plate so that the mounting hardware does not protrude from the glass plate surface.
[0004]
FIG. 8 is a cross-sectional view of a principal part of a conventional plate-like member mounting structure that enables the construction of the outer wall without impairing the continuity of the plate surface.
[0005]
According to this, the plate-like member 1 is provided with mounting holes 20 having a countersink portion 21 on the outdoor side, and the mounting holes 20 are provided with an interposed material made of a suitable material, for example, an aluminum material. A plate-like member mounting hardware 2 is fitted through an annular member 3 formed using a metal material such as a synthetic resin material. The plate member mounting hardware 2 fitted in the mounting hole 20 is fastened and screwed to the plate member by a nut member 5 with a washer member 4 interposed therebetween.
[0006]
The plate-shaped member 1 and the plate-shaped member mounting hardware 2 having such a configuration position the plate hole portion 21 in the mounting hole 20 on the outdoor side, and support the plate-shaped member 1 on the indoor side. Thus, the same plane can be continuously formed by a plurality of plate-like members 1 by supporting each of them in a pivotable manner.
[0007]
In this way, in the facade construction method using perforated tempered glass, the fact that the glass plate surface and the surface of the mounting hardware have no irregularities and constitute a flat wall surface is an excellent design point.
[0008]
However, due to variations in processing accuracy of the plate hole portion of the plate-like member and variations in processing accuracy of the mounting hardware, the mounting hardware is not in a pre-designed position and posture with respect to the plate hole portion of the plate-like member, A concave portion (for example, a retracted portion A in FIG. 8) is formed in the surface portion of the outdoor head of the mounting member for the plate member, or the head of the mounting member protrudes from the surface of the plate member, The plate-like member surface and the outdoor surface of the head of the mounting hardware may be uneven.
[0009]
This not only impairs the design, but also when the plate member mounting hardware is concave with respect to the plate member surface, the sharp edge portion of the end of the annular member is the countersunk surface of the plate member Since there is a possibility that the plate-shaped member is subjected to an external force such as wind pressure, a stress may be intensively generated.
Similarly, when a glass plate is used as the plate member, if the head portion of the plate member mounting hardware is concave with respect to the glass plate surface, the plate member mounting hardware is used for mounting. The processed side of the countersunk portion of the same glass plate mounted in the hole and another glass plate not subjected to the processing of the mounting hole are laminated with a resin intermediate layer such as polyvinyl butyral, that is, a composite plate-like member When the glass plate is attached to another glass plate, the resinous intermediate film is not completely filled in the gap between the plate-like member mounting metal surface on the processed side of the countersunk portion of the glass plate and another glass plate surface. There was a possibility that air bubbles would remain between the metal parts and deteriorated durability and designability.
[0010]
[Problems to be solved by the invention]
The present invention has been made to solve the above-mentioned problems, and uses a plate-like member provided with a mounting hole having a countersunk portion on one side, and the plate-shaped member mounting hardware ( In the mounting structure of a plate-like member that forms a wall surface of a building by attaching a mounting bracket (hereinafter also referred to simply as a mounting bracket), the plate-like member surface and the outdoor side surface of the mounting hardware are flush with each other, and the wall surface having excellent design properties It aims at providing the attachment structure of the plate-shaped member which can be comprised.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, a plate-like member provided with a mounting hole having a countersunk portion on one side, and a plate-like member having no processing of the mounting hole are made of an adhesive layer made of resin. In a plate-shaped member mounting structure in which a plate-shaped member mounting hardware is formed by attaching a plate-shaped member mounting hardware to the countersunk hole via an annular member, using a composite plate-shaped member integrated through At least one of the countersunk part between the plate-like member and the annular member that has been processed for a hole and the countersink part between the metal fitting for attaching the plate-like member and the annular member is made of plastic and has a substantially cross-sectional shape The present invention provides a mounting structure for a composite plate-like member, characterized in that a spacer for position adjustment having an annular shape or a flat annular shape made of plastic and having a cut is inserted.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Figures 1 to 4 is an explanatory diagram showing a Tsuke構forming preparative plate member.
FIG. 1 is a cross-sectional view of the main part of the plate- shaped member mounting structure, and FIG. 2 is an exploded perspective view of the main part of the plate-shaped member mounting structure.
[0013]
The plate- like member 1 is provided with a mounting hole 20 having a countersink portion 21 on the outdoor side of the building. In this mounting hole 20, an interposed material made of an appropriate material, such as an aluminum material, is used. An annular member 3 formed using a metal material or a synthetic resin material is attached between the plate-like member 1 and the annular member 3 of the countersink 21 via a position adjusting spacer 11. A hardware 2 is fitted. The plate member mounting hardware 2 fitted in the mounting hole 20 is tightened and screwed to the plate member 1 by a nut member 5 with a washer member 4 interposed around the indoor side of the mounting hole 20.
[0014]
The spacer 11 for position adjustment is slightly shifted from the predetermined design position and angle of the mounting bracket due to variations in the processing accuracy of the plate hole portion of the plate-shaped member and variations in the processing accuracy of the plate-shaped member mounting bracket. The outdoor head surface protrudes or becomes concave with respect to the outdoor surface of the plate-like member to prevent unevenness, and the outdoor surface of the plate-like member and the outdoor head of the mounting bracket are prevented. This is to adjust the position so that the surface can be flush with the surface, that is, to adjust the thickness of the plate-shaped member mounting hardware in the thickness direction of the plate-shaped member. Since it is tightened by the plate-shaped member mounting hardware 2 and the nut material 5 and receives a compressive force in the thickness direction, it is somewhat hard and directly touches the plate-shaped member. Plate-like part when the plate-like member 1 is a glass plate or the like Not to damage the first material is required. In this respect, the material for the position adjusting spacer is preferably a resin material such as plastic, and is preferably a fluororesin such as Teflon (trade name) from the viewpoint of durability.
[0015]
As the shape of the position adjusting spacer 11, a shape that is interposed between the countersunk portion of the plate member and the mounting bracket, for example, a substantially annular shape that is not so thick is suitable. For example, as shown in FIG. 4, it is desirable that the plate-shaped member has a substantially cross-sectionally C-shaped shape along the shape of the countersink portion 21 of the mounting hole 20 and the mounting bracket mounting hardware. A flat annular shape like the spacer 12 may be formed, and a notch 13 may be provided to follow the shape of the mounting hole 20 of the plate member and the mounting bracket 2.
[0016]
As described above, the position adjusting spacer adjusts the variation in the processing accuracy of the countersunk portion of the plate-shaped member and the variation of the processing accuracy of the metal fitting for mounting the plate-shaped member, and the thickness of the plate-shaped member of the metal for mounting the plate-shaped member is adjusted. The thickness of the position adjusting spacer 11 to be inserted or the number of inserted position adjusting spacers 11 can be adjusted so that the outer side surface of the plate-shaped member and the outer side surface of the mounting hardware can be flush with each other. The unevenness of the plate-like member surface and the mounting hardware surface can be absorbed.
[0017]
When the plate-like member mounting hardware 2 is fitted in the mounting hole 20 of the plate-like member 1 in this way, the washer 6 and the nut are attached to the support mechanism 32 attached to the housing 31 of the building on the indoor side of the building. 7 to support each other firmly and pivotally.
[0018]
FIG. 3 shows a wall surface of a building in which a wall surface is constructed by attaching a support mechanism 32 to a support structure 33 attached to a housing 31 of the building, using the plate member mounting structure made of the glass plate of the present invention. FIG.
[0019]
FIG. 6 shows a cross-sectional view of a relevant part of another example of the plate member mounting structure.
According to the example of this, the plate-like member 1 is mounting hole 20 having a countersink portion 21 to the outdoor side of the building is provided, on the mounting hole 20 is made of an appropriate material interposed An annular member 3 formed using a metal material, for example, a metal material such as an aluminum material, or a synthetic resin material, and a position adjusting spacer 11 between the plate-like member 1 and the annular member 3 of the countersink portion 21. The plate-shaped member mounting hardware 2 is fitted between the annular member 3 and the plate-shaped member mounting hardware 2 via another position adjusting spacer 11 ′. This position adjusting spacer 11 'also provides the same function as the position adjusting spacer 11, and can be used with the same material, shape and configuration.
[0020]
The plate member mounting hardware 2 fitted in the mounting hole 20 is tightened and screwed to the plate member 1 by a nut member 5 with a washer member 4 interposed around the indoor side of the mounting hole 20.
[0021]
Figure 7 shows a fragmentary cross-sectional view of the solid施例mounting structure of the plate-shaped member of the present invention. According to this embodiment, the composite plate-like member 10 made of a glass plate is composed of a plate-like member 8 made of a glass plate having no hole processed portion and a plate member made of a glass plate having a countersunk portion processed portion. 1 is laminated through an adhesive laminated intermediate film 9 made of a resin such as polyvinyl butyral, and is bonded to the plate member (glass plate) 8 and the plate member (glass plate) 1 to constitute a laminated glass. Has been.
[0022]
The plate-like member 1 is provided with a mounting hole 20 having a countersunk portion 21 on the outdoor side. The mounting hole 20 has a metal material such as an interposition material made of an appropriate material, for example, an aluminum material. And the annular member 3 formed using a synthetic resin material, and between the plate-like member 1 and the annular member 3 of the countersunk portion 21, a metal fitting for attaching the plate-like member via a position adjusting spacer 11. 2 is fitted. The plate member mounting hardware 2 fitted in the mounting hole 20 is fastened to the plate member 1 by a nut member 5 with a washer member 4 interposed around the indoor side of the mounting hole 20 of the plate member 1. Screwed.
[0023]
At this time, the position adjusting spacer 11 is used to make the plate-like member surface generated by the processing error of the mounting hole 20 flush with the mounting hardware surface, and the thickness of the spacer 11 to be inserted is changed. Or by adjusting by changing the number of inserted spacers 11 for position adjustment, it becomes possible to absorb the unevenness of the plate member surface and the mounting hardware surface.
[0024]
Accordingly, when the plate-like member 8 and the plate-like member 1 are processed through the adhesive layer 9, the possibility that air bubbles remain between the plate-like member 8 and the mounting hardware 2 is reduced. When is a transparent material such as glass, it is possible to obtain a plate-like member 10 having excellent design properties.
[0025]
【The invention's effect】

It is possible to adjust the access position between the plate-shaped member surface and the mounting hardware surface by inserting a position adjusting spacer made of a resin material into the countersunk part between the member and the mounting hardware for the plate-shaped member Thus, by making the plate member surface and the surface of the head on the outdoor side of the mounting hardware flush with each other, it is possible to provide a plate member attachment structure that is superior in design and has high durability.
[0026]
In addition, by inserting a position adjusting spacer made of a resin material or the like into the countersunk portion between the plate member and the plate member mounting hardware, when the plate member receives an external force such as wind pressure, The position adjusting spacer acts as a buffer material, and the stress generated in the countersunk portion of the plate-like member can be reduced.
[0027]
Furthermore, since the plate-shaped member surface and the outdoor surface of the mounting hardware can be flush with each other, when the plate-shaped member is a glass plate or the like, the same glass in which the mounting hardware for the plate-shaped member is mounted in the mounting hole When the plate countersink side of the plate and another glass plate are laminated via a resin adhesive laminated interlayer such as polyvinyl butyral, separate from the plate member mounting hardware surface on the countersink side of the glass plate It is possible to provide a plate-shaped member mounting structure with excellent durability in which an extra space is not formed between the glass plate surface and bubbles or the like are hardly mixed.
