【発明の属する技術分野】
本発明は、Ｔ字加工表装材及び補修用Ｔ字加工表装材とハット型締結金具及び補修用ハット型締結金具とを組み合わせて、表装材と根太材とを締結する方式に関するものである。
【０００２】
【従来の技術】
代表的な従来の技術は次の通りである。第１の方式は、表装材の上部表面から底面及び表装材底面に接した根太材の深さの一部に至るまでビスを捩じ込むための誘導穴を開けた上、床板の上部表面から底面にかけて、頭付締結用ビスを貫通させ、更に表装材底面に接した根太材に頭付締結ビスの先端をねじ込み、表装材と根太材とを締結する方式であり、表装材の上部表面に頭付締結ビスの頭部が突出しないよう、頭付締結ビスの頭部分を表装材表面以下に埋め込むために、頭付ビス毎に表装材に座彫りを施す必要がある方式であった。第２の方式は、表装材の両側面に本実加工を施し、片面の突出部分の突出根の角から斜めに締結用ビス又はクギを根太材に達するまで捩じ込むか叩き込んで、当該表装材を根太材に締結し、この表装材の突出部分に、隣接させる表装材の溝部分をかぶせることにより、この隣接させる表装材の溝部分がある側面を固定し、さらに、この隣接する表装材の反対側の突出部分の突出根の角から締結用ビス又はクギを根太材に達するまで捩じ込むか叩き込んで、隣接させる表装材を根太材に固定する。これを繰り返すことにより所定の部分を表装する方式であった。第３の方式は、表装材の両側面に溝を成形し、かつ、根太材の表面の両端の長さの方向に、コの字型の溝を開口部を根太材の巾の中心に向けて成形し、工字型金具の上部縁を表装材片側側面の溝に、下部縁を根太材の表面の両端の溝にスライドさせて挿入し、表装材と根太材を固定する方式であった。第４の方式は、表装材の両側面に溝を成形し、相対する表装材の溝に、適度の大きさの中央に締結用ビスが貫通する程度の穴を開けた長方形の金属板を挿入し、相対する表装材の狭い間隔を通して、径が小さい締結用ビスを上記金属板の穴を通して根太材にねじ込み、金属板を表装材の溝の下部面に圧着して、表装材と根太材とを固定する方式であった。
【０００３】
【発明が解決しようとする課題】
従来の技術において述べた、第１の方式では、頭付締結用ビスを表装材を貫通させ、根太材に食い込ませるために、まず、頭付締結用ビスの誘導穴を表装材に開け、その後、頭付締結用ビスを表装材を貫通させた上で根太材に捩じ込む労働的経費的負担、および、頭部を表装材表面より下に埋め込むために、頭付ビス毎に座彫りを施すための労働的経費的負担が大きく、加えて、表装材の上部表面に頭付締結用ビスの頭が露出することに美感上問題があった。第２の方式では、締結用ビス又はクギは隠れるが、突出部分の狭い部分に細工をするため、締結用ビス又はクギの仕様に制限があり、かつ、労働的経費的負担が大きかった。第３の方法では、工字型金具の上下の縁を、床板側面および根太材表面の両方の溝にスライドさせて挿入するため、溝と上下の縁の金属板との僅かな隙間ではあるが、これが競合するため、表装材の根太材に対する固定強度が甘いという構造上の問題、および、部品の種類が多くなるという経費的負担の問題があった。第４の方式では、締結用ビスの仕様が相対する表装材の狭い間隔に制限されるため、表装の構造強度が十分に得られないという問題があった。
【０００４】
【課題を解決するための手段】
本発明は、Ｔ字加工表装材の厚さの中央部から下部にかけて、長さの方向に成形した外部からは見えないラッチ溝および欠落空間にハット型締結金具を設置する為、ハット型締結用金具を根太材に締結する頭付締結用ビスの捩じ込みについて、長い誘導穴を開けたり、ビス頭部のための座彫りを施したりする必要がなく施工能率が上がる。また、Ｔ字加工表装材の厚さの中央部から下部にかけての欠落空間では、十分な空間を確保できるため、十分に強度のある頭付締結用ビスを使用し、ハット型締結用ビスの縁が表装材のラッチ溝の下面を十分な圧迫強度で押し付けＴ字加工表装材を根太材に十分な強度で固定することが出来る。Ｔ字加工表装材の加工は、切削刃や押出型材を取り替えるだけで、４面が平面である通常の表装材を加工するのと同等の手間で成形することができ、根太材も従来技術の内、第１および第２の方法で使用するものと同じものである。締結用具は、通常のタッピングビスからハット型締結金具に代えられているが、単純構造であり、製作は簡単である。補修用Ｔ字加工表装材および補修用ハット型締結金具についても、施工能率が高いこと、および、製作が簡単であることの両面において、上記のＴ字加工表装材とハット型締結金具の場合と同様である。以上により、従来の技術の内、第１の方法における施工手間がかかる問題、および、締結用ビスの頭部露出が煩わしいという美感上の問題、第２の方法における表装材と根太材との固定強度が制限されるという問題、第３の方法における表装材と根太材との固定強度が甘いという問題、および、部品が多く構造が複雑であるという問題、第４の方法における締結用ビスの仕様が制限されるために表装材と根太材との固定強度が十分に取れないという問題のいずれの問題点をも解決し、経費的労働的負担の軽減を図ることができ、美感上の改善も図ることができる。
【０００５】
【発明の実施の形態】
まず、根太材の上部表面に適切な間隔で、ハット型締結金具を、頭付締結用ビスをハット型締結金具のビス穴を通して根太材にねじ込むことによって設置する。次に、Ｔ字加工表装材を、根太材に直角になる方向で根太材の上に置き、Ｔ字加工表装材の片側のラッチ溝にハット型締結金具の片側の縁が挿入されるようにして、そのＴ字加工表装材を先に設置したハット型締結金具に押し付ける。Ｔ字加工表装材は、そのラッチ溝より下部の側面が、金具のＵ字部分の側面に押し付けられた位置で止まる。次に、根太材上で、そのＴ字加工表装材のもう一方の側面のラッチ溝に、別のハット型締結金具の一方の縁がはまり込む様にそのハット型締結金具を押し付けた上、ハット型締結金具のＵ字底面に開けられたビス穴を通して頭付締結用ビスを根太材にねじ込むことによってハット型締結金具を根太材に締結する。これにより、Ｔ字加工表装材は根太材に固定される。これを繰り返すことにより表装面を完成させる。また、表装完成後、Ｔ字加工表装材の部分的取替補修が必要となった場合には、補修用Ｔ字加工表装材と補修用ハット型締結金具を使用する。まず、補修を要するＴ字加工表装材、および、存続しているＴ字加工表装材の側面から部分的に露出しているハット型締結金具の内、頭部が存続しているＴ字加工表装材の巾からはみ出している頭付締結用ビスにより固定されているハット型締結金具を除去し、その除去したハット型締結金具の位置の周辺付近で、補修用ハット型締結金具の片側の縁を、存続している表装材のラッチ溝にねじ込んだ上で、この補修用ハット型締結金具を頭付締結用ビスにて根太材に固定する。次に補修用Ｔ字加工表装材の上部側面の下部の角が長さの方向に斜めにカットされている側面のラッチ溝を、除去しなかったハット型締結金具の縁にねじ込んだ上、この補修用Ｔ字加工表装材の反対側側面を、置き換えられた補修用ハット型締結金具の露出した縁に、この側面に成形してある補修用Ｔ字加工表装材の金具縁逃げ溝を被せるようにして、この補修用Ｔ字加工表装材全体を、補修のため除去した表装材の空間にはめ込み、その表面が存続する表装材の表面と同じレベルになるように根太材の上に置く。さらに、補修用ハット型締結金具の側に生じた表装材間の隙間に、適度の厚さの平面ドライバーを突っ込み、その先端を補修用ハット型締結金具のＵ字部分の底面で長方形平板にて延長されている部分の先端に斜めにあてがい、このドライバーをハンマーにて叩いて、補修用ハット型締結金具の縁がラッチ溝に食い込むまでスライドさせることにより、補修用Ｔ字加工表装材を根太材に固定できる。
【０００６】
【実施例】
以下、添付図面に従って一実施例を説明する。１はＴ字加工表装材、２はハット型締結金具、３は補修用Ｔ字加工表装材、４は補修用ハット型締結金具、５は根太材、６は頭付締結用ビス、７はドライバー、８はハンマーである。
【０００７】
２ｃはハット型締結金具のＵ字底面に開けられたビス穴で、これを通して頭付締結用ビス６を根太材５にねじ込み、ハット型締結金具２を根太材５に設置する。１ａは、ラッチ溝で、この溝にハット型締結金具の縁２ａが食い込むことにより、Ｔ字加工表装材１と根太材５が締結される。この場合、ハット型締結金具の両方のＵ字側面２ｂが、相対するＴ字加工表装材の下部欠落部分の側壁１ｂで押し止められることにより、両方の相対するＴ字加工表装材の隙間が所定の巾で得られる。頭付締結用ビス６は、Ｔ字加工表装材のかぶさり部分１ｃで隠されるので、頭付締結用ビスの頭部を表装材の表面以下に沈ませるための座彫りや、頭付締結用ビスの配列を整えて美観を保つための細工をする必要がない。また、頭付締結用ビスの頭部が表装材表面に露出するという、美観的煩わしさを避けることができる。
【０００８】
表装の完成後、Ｔ字加工表装材の部分的取替補修が必要となった場合には、補修用Ｔ字加工表装材３と補修用ハット型締結金具４を使用する。まず、補修を要するＴ字加工表装材９、および、存続しているＴ字加工表装材の側面から部分的に露出しているハット型締結金具の内、頭部が、存続しているＴ字加工床板の巾からはみ出している頭付締結用ビスにより固定されているハット型締結金具１０を除去し、補修用ハット型締結金具の片側の縁４ａ−２を存続しているＴ字加工表装材のラッチ溝１ａにねじ込んだ上で、この補修用ハット型締結金具４を頭付締結用ビス６にて根太材に固定する。補修用Ｔ字加工表装材の上部側面の下角が長さの方向に斜めにカットされている側面３ｅは、補修用Ｔ字加工表装材のラッチ溝３ａ−１に、ハット型締結金具の縁２ａを、容易に食い込ませることを目的としている。３ａ−１を２ａに食い込ませた後、補修用Ｔ字加工表装材の底面３ｆを、根太材５の上に降ろす。この場合、補修用Ｔ字加工表装材の金具縁逃げ溝３ｂに、先に根太材上に固定した補修用締結金具の縁４ａ−１がはまり込むために、補修用Ｔ字加工表装材の表面を両脇の既存のＴ字加工表装材１１の表面と同じ高さに保つことができる。次に、３と１１の隙間から適切な厚さの平ドライバー７を差し込んで、その先端を補修用締結金具のＵ字底部の延長部分４ｅにあてがった上、ドライバーの頭部７をハンマー８で打ち、補修用締結ハット型締結金具４をスライドさせることにより、補修用締結ハット型締結金具の縁４ａ−１を、補修用Ｔ字加工表装材のラッチ溝３ａ−２に食い込ませることにより補修用Ｔ字加工表装材３を根太材５に締結する。
【０００９】
【発明の効果】
表装材をＴ字加工表装材の形状に加工し、かつ、これにハット型締結金具を組み合わせるという簡単な方法により、次のような効果が得られる。ハット型締結金具および頭付締結用ビスが、Ｔ字加工床板表装材に露出しないため、それらを根太材に固定するには、作業能率と経費効率を上げる点のみを考慮した施工方法でよいこと、および、Ｔ字加工表装材の下部に成形した欠落部分の側壁の奥行きと、ハット型締結金具のＵ字部分の広がり巾とを調整することにより、Ｔ字加工表装材間の隙間を一律に所定の巾にすることができ、施工に当ってその間隔を一律にするための細工が不要となることにより、労働的経費的負担の軽減を図ることができる。さらに、ハット型締結金具が、Ｔ字加工表装材表面に露出しないため、頭付締結用ビスの頭部を表装材の表面以下に沈ませるための座彫りや，頭付締結用ビスの配列を整えて美観を保つための細工をする必要がなく、労働的経費的負担の軽減を図ることができる。また、頭付締結用ビスの頭部が表装材表面に露出するという、美観的煩わしさを避けることができ、表装の美観を改善することができる。表装材の取替補修をする場合にも、補修用Ｔ字加工表装材と補修用ハット型締結金具の組合せにより、上記と同様の効果がある。

[0002]
[Prior art]
A typical conventional technique is as follows. The first method is to form a guide hole for screwing a screw from the top surface of the facing material to the bottom surface and a part of the depth of the joist material in contact with the bottom surface of the facing material, and then from the top surface of the floorboard. Through the bottom surface, the head fastening screw is penetrated, and the tip of the head fastening screw is further screwed into the joist that is in contact with the bottom surface of the facing material, and the top material and the joist material are fastened. In order to embed the head portion of the headed fastening screw below the surface of the surface mounting material so that the head of the headed fastening screw does not protrude, it was necessary to perform carving on the surface mounting material for each headed screw. In the second method, the actual processing is performed on both sides of the facing material, and a fastening screw or a nail is screwed or hammered obliquely from the corner of the protruding root of the protruding portion on one side until the joist material is reached. The material is fastened to the joist, and the projecting portion of the facing material is covered with the groove portion of the neighboring facing material, thereby fixing the side surface where the groove portion of the neighboring facing material is located. A fastening screw or a nail is screwed or beaten from the corner of the protruding root of the protruding portion on the opposite side to the joist until the adjoining surface material is fixed to the joist. By repeating this, a predetermined portion is covered. In the third method, grooves are formed on both sides of the facing material, and a U-shaped groove is formed in the direction of the length of both ends of the surface of the joist with the opening directed toward the center of the width of the joist. The upper edge of the work-type metal fitting was inserted into the groove on one side surface of the facing material, and the lower edge was slid into the grooves at both ends of the surface of the joist material, and inserted to fix the facing material and the joist material. . In the fourth method, grooves are formed on both side surfaces of the facing material, and a rectangular metal plate having a hole in the opposite facing material groove having an appropriate size at the center and through which a fastening screw penetrates is inserted. Then, through the narrow gap between the facing facing materials, screw a fastening screw having a small diameter into the joist through the hole of the metal plate, press the metal plate against the lower surface of the groove of the facing material, and attach the facing material and the joist material. Was fixed.
[0003]
[Problems to be solved by the invention]
In the first method described in the prior art, in order to make the heading fastening screw penetrate the surface material and bite into the joist, first, a guide hole of the heading fastening screw is opened in the surface material, and thereafter, In order to embed the headed fastening screws into the joists after penetrating the facing material, and to embed the head below the surface of the facing material, perform carving for each headed screw. There is a large labor and cost burden to apply, and in addition, there is an aesthetic problem in that the head of the headed fastening screw is exposed on the upper surface of the facing material. In the second method, the fastening screw or the nail is hidden, but the narrow portion of the protruding portion is worked, so that the specification of the fastening screw or the nail is limited, and the labor cost is large. In the third method, since the upper and lower edges of the metal mold fitting are slid into the grooves on both the side surface of the floorboard and the surface of the joist material, there is a slight gap between the grooves and the metal plates on the upper and lower edges. However, there is a structural problem that the fixing strength of the facing material to the joist material is weak, and a problem of a cost burden that the number of types of parts increases. In the fourth method, there is a problem that the structural strength of the front covering cannot be sufficiently obtained because the specification of the fastening screw is limited to a narrow interval between facing facing materials.

【The invention's effect】
The following effects can be obtained by a simple method of processing the surface material into a T-shaped processed surface material and combining it with a hat-type fastener. Since the hat-type fastening metal and the head-type fastening screws are not exposed to the T-shaped processed floor panel surface covering material, fixing them to the joists requires a construction method that only considers the work efficiency and cost efficiency. By adjusting the depth of the side wall of the missing portion formed at the lower part of the T-shaped processed surface covering material and the spread width of the U-shaped portion of the hat-type fastening metal, the gap between the T-shaped processed surface mounting materials can be uniform. The width can be set to a predetermined value, and work is not required to make the intervals uniform during construction, so that labor costs can be reduced. In addition, since the hat-type fastener is not exposed on the surface of the T-shaped processed outer cover material, it is necessary to employ a countersink for lowering the head of the head-mounted fastener below the surface of the outer cover material and an arrangement of the head-mounted fastener. There is no need to make any work to maintain the appearance and aesthetic appearance, thereby reducing labor costs. In addition, it is possible to avoid the aesthetic troublesomeness of exposing the head of the headed fastening screw to the surface of the surface material, thereby improving the beauty of the surface. When replacing and repairing the surface material, the same effect as described above can be obtained by combining the T-shaped processed surface material for repair and the hat-type fastening metal fitting for repair.
