Description

【０００１】
【発明の属する技術分野】
本発明は、レベル調整器具及び下地組工法、並びに、下地に関する。
【０００２】
【従来の技術】
コンクリート壁等の躯体に石膏ボード等の表面材を取り付けるための金具装置、及び、かかる金具装置を使用した施工法が、例えば、特開昭６１−５７７５７号公報から公知である。この金具装置は、特開昭６１−５７７５７号公報に添付された第１図に示されているように、ベース金具Ａと、調節金具Ｂから構成されており、ベース金具Ａは、基板１と、基板１に植立されたスタッドボルト２から構成され、調節金具Ｂは、台板４と、台板４に回転自在に起立され、スタッドボルト２と螺合する雌ネジ筒子６から構成されている。
【０００３】
そして、コンクリート壁等の躯体に石膏ボード等の表面材を取り付けるために、先ず、ベース金具Ａをアンカー１１を使用して躯体に固定し、スタッドボルト２に雌ネジ筒子６を螺合させる。次いで、野縁金具Ｃを調節金具Ｂに設けられた腕板５に取り付けた後、野縁金具Ｃの表面板７の開口７ａを通して調節金具Ｂの雌ネジ筒子６の先端部に設けられた受入孔６ａにプラスドライバーを係合させて、雌ネジ筒子６を回転させる。これによって、躯体に対する調節金具Ｂの高さ位置を調節することができ、しかも、間隔をおいて固定されている複数の金具装置における各調節金具の高さ位置の不揃いを矯正することができるとされている。
【０００４】
【発明が解決しようとする課題】
しかしながら、特開昭６１−５７７５７号公報に開示された金具装置では、ドライバー等を用いて躯体に対する調節金具Ｂの高さ位置を調節するので、その作業が繁雑であるし、作業効率が余り良くなく、工期の短縮化を図り難いといった問題がある。
【０００５】
従って、本発明の目的は、躯体表面に凹凸（不陸）が存在していても、躯体表面と表面材との間の間隔を容易に調節することができ、高い作業効率を得ることができるレベル調整器具、並びに、かかるレベル調整器具を使用した下地組工法及び下地を提供することにある。
【０００６】

から構成された下地であって、
該レベル調整器具は、

から構成されており、
固定部材は、底面、並びに、取付部を構成する対向した第１の側面及び第２の側面を有 し、
第１の側面及び第２の側面のそれぞれには、表面材取付部材の第１のリップ部及び第２のリップ部と係合する凸部が設けられており、
各凸部は、上辺が下辺よりも短い略二等辺台形形状を有する第１の台形部と、第１の台形部の上辺から延在し、上辺が下辺よりも短い略二等辺台形形状を有する第２の台形部とから成り、
第２の台形部の下辺は、第１の台形部の上辺端部から側面底部に向かう方向に延びており、
表面材取付部材の第１のリップ部の外面が、第１の側面及び第２の側面に設けられた第１の台形部の一方の側辺と係合し、表面材取付部材の第１のリップ部の先端部が、一方の側辺側の第１の台形部の上辺端部から延びる第２の台形部の下辺と係合しており、

【００１１】
本発明のレベル調整器具、下地組工法あるいは下地（以下、これらを総称して、単に、本発明と呼ぶ場合がある）においては、レベル調整治具材は円盤状であり、その中心部においてナット部材の外周部に固定されている構成とすることが好ましい。これによって、例えば、作業員が手でレベル調整治具材の外周部を一層確実に把持し、一層容易に容易にレベル調整治具材を回動させることができる。
【００１２】
本発明にあっては、固定部材を上述したような構造とすることによって、表面材取付部材を取付部に容易に、且つ、短時間で、しかも、ワンタッチで取り付けることが可能となるし、表面材取付部材のリップ部と取付部の係合が一層強固なものとなり、取付部と表面材取付部材との間に極めて高い係合力を得ることができる。
【００１３】
これらの各種の構成、構造を含む本発明にあっては、ベース部材は、躯体に固定されるプレート、及び、このプレートに取り付けられたネジ部材から成ることが好ましい。このような構造にあっては、ネジ部材はプレートから略垂直に延びるようにプレートに取り付けられている。尚、かかる構造を有するベース部材を、便宜上、第１の構造を有するベース部材と呼ぶ。そして、この場合、ネジ部材の頂部をプレートに溶接法や接着剤を使用して取り付けてもよいが、プレートにはネジ山が切られた螺合部が設けられ、ネジ部材を螺合部を螺合させることによってネジ部材はプレートに取り付けられている構造とすることが好ましい。螺合部は、例えば、プレートに絞り加工を施した後、絞り加工部分にネジ山を切ることによって、プレートに形成することができる。あるいは又、螺合部を、プレートに溶接されたナットやタップネジから構成することもできる。このような構造とすることで、固定部材とベース部材との間の間隔を所望の間隔にするために、ネジ部材を容易に交換することができる。躯体へのプレートの固定方法として、ウレタン系やエポキシ系の接着剤を用いる方法、アンカーボルトやセパレータを用いる方法を例示することができる。プレートは平板状であってもよいし、例えばＺ型の形状を有してしてもよい。
【００１４】
あるいは又、これらの各種の構成、構造を含む本発明にあっては、
躯体は、略リップ溝形の断面形状を有し、第１のリップ部及び第２のリップ部を備えたバー状の躯体部材から構成されており、
ベース部材は、躯体部材と係合する係合部材、及び、係合部材に取り付けられたネジ部材から成り、
係合部材は、底面、及び、対向した第１の側面及び第２の側面を有する構造とすることができる。溶接法や接着剤によって、あるいは、補助器具を用いて、第１の側面及び第２の側面を躯体部材に取り付けてもよいが、第１の側面及び第２の側面を躯体部材に、例えばボルトとナット、あるいはタッピング・スクリューやセルフ・ドリリング・スクリューといった各種のスクリューを用いて容易に取り付けることができる。尚、第１の側面及び第２の側面のそれぞれには、ボルトあるいは各種のスクリューでの取り付けを容易にするために、貫通孔が設けられていてもよい。躯体部材は、適切な方法によって躯体本体に固定すればよい。
【００１５】
更には、このような構造を有する係合部材にあっては、
第１の側面及び第２の側面のそれぞれには、躯体部材の第１のリップ部及び第２のリップ部と係合する凸部が設けられている構造とすることができる。尚、かかる構造を有するベース部材を、便宜上、第２の構造を有するベース部材と呼ぶ。ベース部材をこのような第２の構造とすることによって、ベース部材を躯体部材に容易に、且つ、短時間で、しかも、ワンタッチで取り付けることが可能となる。
【００１６】
第２の構造を有するベース部材における係合部材において、
各凸部は、上辺が下辺よりも短い略二等辺台形形状を有する第１の台形部と、第１の台形部の上辺から延在し、上辺が下辺よりも短い略二等辺台形形状を有する第２の台形部とから成り、
第２の台形部の下辺は、第１の台形部の上辺端部から側面底部に向かう方向に延び、
躯体部材の第１のリップ部が、第１の側面及び第２の側面に設けられた第１の台形部の一方の側辺、及び、一方の側辺側の第１の台形部の上辺端部から延びる第２の台形部の下辺と係合し、
躯体部材の第２のリップ部が、第１の側面及び第２の側面に設けられた第１の台形部の他方の側辺、及び、他方の側辺側の第１の台形部の上辺端部から延びる第２の台形部の下辺と係合する構造とすることが好ましい。尚、かかる構造を有するベース部材を、便宜上、第３の構造を有するベース部材と呼ぶ。ベース部材をこのような第３の構造とすることによって、躯体部材のリップ部と係合部材の係合が一層強固なものとなり、ベース部材と躯体部材との間に高い係合力を得ることができる。
【００１７】
固定部材、あるいは、第３の構造を有するベース部材において、第１の台形部は略二等辺台形形状を有していると表現しているが、これは、第１の台形部が厳密に二等辺台形でなくともよいことを意味する。即ち、台形の２つの側辺の長さが厳密には等しくなくともよいし、上辺と下辺が厳密には平行でなくともよい。また、第２の台形部も略二等辺台形形状を有していると表現しているが、これは、第２の台形部が厳密に二等辺台形でなくともよいことを意味する。即ち、台形の２つの側辺の長さが厳密には等しくなくともよい。更には、第２の台形部における下辺は一直線ではないし、上辺と下辺とは平行でないが、第２の台形部は巨視的には台形形状であるが故に、略二等辺台形形状を有していると表現する。尚、第１の側面及び第２の側面のそれぞれの第２の台形部の下辺と第１の台形部の上辺端部とが交差する領域よりも第２の台形部の内部にまで、第２の台形部の下辺が延在している構成とすることもできる。尚、第２の台形部の内部にまで延在した第２の台形部の下辺の部分を、便宜上、切欠部と呼ぶ。このような切欠部を設けることによって、取付部と表面材取付部材との係合、あるいは、ベース部材と躯体部材との係合を更に一層強固なものとすることができる。
【００１８】
本発明において、表面材取付部材あるいは躯体部材の断面形状が略リップ溝形であるとは、以下の形状であることを意味する。即ち、表面材取付部材あるいは躯体部材を長手方向と直角の方向で切断したときの断面形状は、「Ｕ」字あるいは「コ」の字の両端が、それぞれ、内側に折れ曲がった形状、あるいは、「Ｕ」字あるいは「コ」の字の両端が、それぞれ、内側に折れ曲がり、更に、下方に（底部に向かって）折れ曲がった形状である。第１のリップ部及び第２のリップ部は、表面材取付部材あるいは躯体部材の長手方向に延びる縁部のそれぞれに該当している。表面材取付部材あるいは躯体部材は、例えば、ＪＩＳ Ｇ３３５０（一般構造用軽量形鋼）によって規定された一般構造用軽量形鋼、亜鉛メッキされた軽量形鋼、ステンレス鋼、アルミニウム、チタンといった各種金属材料や合金材料から作製することもできるし、射出成形法等に基づき合成樹脂から作製することもできる。
【００１９】
ベース部材やレベル調整治具材、固定部材も、表面材取付部材あるいは躯体部材と同様の材料から作製することができる。尚、ベース部材やレベル調整治具材、固定部材を構成する材料と、表面材取付部材あるいは躯体部材を構成する材料とは、同じ材料であっても、同種の材料であっても、異種の材料であってもよい。更には、ベース部材、レベル調整治具材及び固定部材のそれぞれを構成する材料は、同じ材料であっても、同種の材料であっても、異種の材料であってもよい。ネジ部材は、金属やプラスチックスから形成することができる。
【００２０】
本発明におけるレベル調整器具と表面材取付部材の組合せとして、具体的には、胴縁受けと胴縁、野縁受けと野縁を例示することができる。表面材として、内装材や外装材を挙げることができる。具体的には、ステンレス鋼板やアルミニウム板、鉄板、鋼板、亜鉛メッキ鋼板、塩ビ鋼板といった各種の金属製の平板や波板、スパンドレール、化粧石膏ボードを含む石膏ボード、ケイ酸カルシウム板、スラグ石膏板、木毛セメント板、パルプセメント板、木片セメント板、抄造石膏板、モルタル板、ロックウール板、木質系壁材、合板、木質繊維板、化粧パルプセメント板、ガラス繊維やカーボン繊維入りボード、石綿セメント板、石綿スレートパネル、セラミックス板といった窯業材料から構成された板を例示することができる。また、躯体あるいは躯体本体（これらを総称して、躯体等と呼ぶ場合がある）として、軽量鉄骨造や、木質構造（木骨造、枠組壁工法、木質プレハブ構造を含む）、トンネルの内壁、コンクリート製高架橋の壁面、コンクリート製外壁やコンクリート造壁、コンクリート・ブロック、ＡＬＣ板、レンガ造、あるいは、天井スラブや床スラブを例示することができ、あるいは又、これらの表面に、例えば、ステンレス鋼板やアルミニウム板、鉄板、鋼板、亜鉛メッキ鋼板、塩ビ鋼板を取り付けたものを例示することができる。
【００２１】
所望に応じて、躯体等の上、及び、躯体等と表面材取付部材との間、あるいは、躯体部材と表面材取付部材との間に断熱材を挿入してもよく、これによって高い結露防止効果を得ることができる。断熱材として、フェルト状のグラスウールやロックウール；ボード状のグラスウールやロックウール、インシュレーションボード；ばら状のグラスウールやロックウール、セルローズファイバー；ボード状のポリスチレンフォームやウレタンフォームを例示することができる。
【００２２】
本発明においては、例えば、作業員が手でレベル調整治具材の外周部を把持し、容易にレベル調整治具材を回動させることができ、これによって、ネジ部材の軸線方向に沿って固定部材を移動させ、固定部材とベース部材との間の間隔を極めて容易に調整することが可能となる。
【００２３】
【発明の実施の形態】
以下、図面を参照して、発明の実施の形態（以下、実施の形態と略称する）に基づき本発明を説明する。
【００２４】
（実施の形態１）
実施の形態１は、本発明のレベル調整器具及び下地組工法、並びに、下地に関する。実施の形態１のレベル調整器具の分解斜視図を図１に示し、模式的な断面図を図２に示し、組立前のレベル調整部材の模式的な分解断面図を図３に示す。また、固定部材の側面の模式的な拡大図を図４に示し、表面材取付部材と取付部の係合状態を模式的に図５に示す。
【００２５】
実施の形態１のレベル調整器具は、ベース部材１０及びレベル調整部材２０から成る。実施の形態１において、ベース部材は第１の構造を有する。
【００２６】
実施の形態１において、ベース部材１０は、ネジ部材１２を有し、躯体６０に固定される。より具体的には、ベース部材１０は、躯体６０に固定される平板のプレート１１、及び、このプレート１１に取り付けられたネジ部材１２から成る。金属製のネジ部材１２は、具体的には、その頂部が、レベル調整部材２０側のプレート１１の表面に溶接されて取り付けられている。実施の形態１においては、プレート１１を亜鉛鉄板あるいはステンレス鋼板から作製した。
【００２７】
レベル調整部材２０は、ナット部材２１、レベル調整治具材２２、及び、固定部材２３から構成されている。ナット部材２１は、ネジ部材１２と螺合する。レベル調整治具材２２は、ナット部材２１の外周部に固定されている。固定部材２３には、表面材取付部材５０を取り付けるための取付部が設けられている。そして、固定部材２３は、ナット部材２１の外周部に回動自在に取り付けられ、且つ、レベル調整治具材２２のネジ部材１２に対する回動に連動してネジ部材１２の軸線方向に沿って移動自在である。レベル調整治具材２２は円盤状であり、その中心部においてナット部材２１の外周部に固定されている。レベル調整治具材２２の外周部を折り曲げておくことで、レベル調整治具材２２の強度を向上させることができる。実施の形態１においては、ナット部材をステンレス鋼から作製し、レベル調整治具材２２及び固定部材２３を、亜鉛鉄板あるいはステンレス鋼板から作製した。
【００２８】
ナット部材２１、レベル調整治具材２２及び固定部材２３の組立は、以下の方法にて行うことができる。即ち、例えば、一端に拡大部２１Ａを有し、拡大部２１Ａの中央から管状部２１Ｂが延び、断面形状が「Ｔ」字状であり、管状部２１Ｂの内面にネジ山が切られたナット部材２１を準備する。尚、管状部２１Ｂの外面がナット部材２１の外周部に該当する。一方、中央部に突起部２２Ａが設けられたレベル調整治具材２２を準備する。突起部２２Ａには貫通孔２２Ｂが設けられており、貫通孔２２Ｂの内径と管状部２１Ｂの外径とは略等しい。更には、中央部に貫通孔２３’が設けられた固定部材２３を準備する。固定部材２３に設けられた貫通孔２３’の直径は、レベル調整治具材２２に設けられた突起部２２Ａの外径よりも大きい。
【００２９】
そして、ナット部材２１の管状部２１Ｂにレベル調整治具材２２の中央部に設けられた突起部２２Ａを挿入し、レベル調整治具材２２をナット部材２１の外周部（具体的には、管状部２１Ｂ）に固定する。更に、レベル調整治具材２２に設けられた突起部２２Ａに、固定部材２３の中央部に設けられた貫通孔２３’を挿入する。そして、ナット部材２１の管状部の他端をかしめて、他端を拡大することによって（図２の参照番号２１Ｃを参照）、ナット部材２１、レベル調整治具材２２及び固定部材２３の組立を完了する。固定部材２３に設けられた貫通孔２３’の直径がレベル調整治具材２２に設けられた突起部２２Ａの外径よりも大きいので、固定部材２３は、ナット部材２１の外周部（具体的には、レベル調整治具材２２に設けられた突起部２２Ａ）に回動自在に取り付けられた状態となる。
【００３０】
実施の形態１において、取付部に取り付けるべき表面材取付部材５０は、略リップ溝形の断面形状を有し、第１のリップ部５１及び第２のリップ部５２を備えたバー状の部材である。また、固定部材２３は、形状が略矩形の底面２４と、底面２４の対向する各辺から略垂直方向に延びる、対向した２つの側面２５と、底面２４の他の対向する各辺から略垂直方向に延びる、対向した２つの突出部２７から構成されている。側面２５が取付部に該当する。第１の側面２５及び第２の側面２５のそれぞれには、表面材取付部材５０の第１のリップ部５１及び第２のリップ部５２と係合する凸部２６が設けられている。
【００３１】
取付部において、各凸部２６は、上辺３２が下辺３１よりも短い略二等辺台形形状を有する第１の台形部３０と、第１の台形部３０の上辺３２から延在し、上辺４４が下辺４３よりも短い略二等辺台形形状を有する第２の台形部４０とから成る。そして、第２の台形部４０の下辺４１，４２は、第１の台形部３０の上辺端部から側面底部に向かう方向に延びている。尚、第２の台形部４０の下辺４３は、第１の台形部３０の上辺３２と共通である。図４においては、これらの第２の台形部４０の下辺４１，４２の延びる方向を一点鎖線で表示した。第２の台形部４０の下辺４１，４２の延びる方向と水平線の成す角度θ2（図４参照）は、８度乃至２４度であることが好ましい。尚、実施の形態１においては、θ2を８度とした。ここで、参照番号４５，４６は、第２の台形部４０の側辺である。尚、第２の台形部４０の形状を言い換えれば、矩形若しくは等しい長さを有する台形（かかる矩形若しくは台形は下辺４３、上辺４４を有する）と、矩形の対向する２辺若しくは台形の側辺にそれぞれ接する三角形（三角形の２辺は、下辺４１，４２及び側辺４５，４６である）が組み合わされた形状（全体としては六角形）である。尚、突出部２７を側面２５と同じ構造としてもよい。
【００３２】
実施の形態１における表面材取付部材５０の断面形状は略リップ溝形である。即ち、表面材取付部材５０を長手方向と直角の方向で切断したときの断面形状は、「Ｕ」字あるいは「コ」の字の両端が、それぞれ、内側に折れ曲がり、更に、下方に（底部に向かって）折れ曲がった形状である。第１のリップ部５１及び第２のリップ部５２は、表面材取付部材５０の長手方向に延びる縁部のそれぞれに該当している。実施の形態１においては、表面材取付部材５０を、厚さ０．４５ｍｍ乃至１．２ｍｍの亜鉛鉄板あるいはステンレス鋼板から作製した。
【００３３】
そして、表面材取付部材５０の第１のリップ部５１は、第１の側面２５及び第２の側面２５に設けられた第１の台形部３０の一方の側辺３３、及び、一方の側辺３３側の第１の台形部３０の上辺端部から延びる第２の台形部４０の下辺４１と係合する。一方、表面材取付部材５０の第２のリップ部５２は、第１の側面２５及び第２の側面２５に設けられた第１の台形部３０の他方の側辺３４、及び、他方の側辺３４側の第１の台形部３０の上辺端部から延びる第２の台形部４０の下辺４２と係合する。第１の台形部３０の側辺３３，３４と垂線の成す角度θ1（図４参照）は、１５度乃至２０度であることが好ましい。尚、実施の形態１においては、θ1を１５度とした。ここで、例えば、レベル調整器具を野縁受けとしたとき、表面材取付部材５０はシングル野縁に相当する。
【００３４】
レベル調整器具と係合させる前の各種の表面材取付を長手方向と直角の方向で切断したときの模式的な断面図を図６に模式的に例示する。図６の（Ａ）及び（Ｂ）に示す表面材取付部材５０においては、「Ｕ」字あるいは「コ」の字の両端が、それぞれ、内側に折れ曲がり（参照番号５５，５６で示す）、更に、下方に（底部に向かう方向であり、図６においては紙面の上方に向かって）折れ曲がった（参照番号５７，５８で示す）形状である。図６の（Ａ）においては、内側に折れ曲がった部分５５，５６と、下方に折れ曲がった部分５７，５８の角度との成す角度は約９０度である。一方、図６の（Ｂ）においては、内側に折れ曲がった部分５５，５６と、下方に折れ曲がった部分５７，５８の角度との成す角度は鈍角である。図６の（Ｃ）に示す表面材取付部材５０においては、「Ｕ」字あるいは「コ」の字の両端が、それぞれ、内側に折れ曲がっている。表面材取付部材５０の側面５３，５４と、内側に折れ曲がった部分５５，５６の成す角度は鋭角である。
【００３５】
実施の形態１の下地組工法においては、先ず、例えばコンクリート壁から成る躯体６０にベース部材１０を固定する。具体的には、プレート１１に設けられた貫通孔を介して躯体６０にアンカーボルト６１を打ち込み、ナット６２を用いてプレート１１を固定する。尚、プレート１１に設けられた貫通孔の平面形状を長円あるいは長方形、角を丸めた長方形とすれば、躯体６０に対するプレート１１の位置決め、あるいは位置の調整を容易に行うことができる。また、プレート１１の対向する二辺を折り曲げておけば、プレート１１の強度を向上させることができる。
【００３６】
次に、ベース部材１０のネジ部材１２と、レベル調整部材２０のナット部材２１とを螺合させて、レベル調整部材２０をベース部材１０に取り付け、作業員が手でレベル調整治具材２２の外周部を把持し、レベル調整治具材２２を回動させることによって、ネジ部材１２の軸線方向に沿って固定部材２３を移動させ、固定部材２３とベース部材１０との間の間隔を調整する。尚、この調整は、一種の予備調整である。
【００３７】
その後、表面材取付部材５０を、固定部材２３に設けられた取付部に取り付ける。具体的には、固定部材２３における第１の側面２５及び第２の側面２５のそれぞれに設けられた凸部２６と、表面材取付部材５０の第１のリップ部５１及び第２のリップ部５２と係合させる。その後、タッピング・スクリューやセルフ・ドリリング・スクリューといったスクリュー２８を用いて固定部材２３の突出部２７に表面材取付部材５０を止め、表面材取付部材５０が固定部材２３に対して移動しないようにする。次いで、レベル調整治具材２２を回動させることによって、ネジ部材１２の軸線方向に沿って固定部材２３を移動させ、固定部材２３とベース部材１０との間の間隔を本格的に調整し、複数の表面材取付部材５０のレベルを出来る限り一致させる。その後、表面材取付部材５０に、例えばアルミニウム板から成る表面材６３をスクリュー等を用いて取り付けることで、下地組工法を完了させる（図７参照）。
【００３８】
以上のとおり、躯体６０の表面に凹凸（不陸）が存在していても、躯体の表面と表面材との間の間隔を、レベル調整器具を用いることによって、極めて容易に調節することができ、高い作業効率を得ることができる。
【００３９】
尚、躯体が天井スラブ６０Ａである場合に、実施の形態１のレベル調整器具及び下地組工法を適用した例におけるレベル調整器具の分解斜視図を、図８に示す。
【００４０】
平板状のプレート１１の代わりに、Ｚ型の形状を有するプレート１１Ａから構成されたベース部材１０Ａを備えたレベル調整器具の分解斜視図を図９に示し、側面図を図１０に示す。「Ｚ］字の一方の横棒の部分を、例えばアンカーボルト６１を用いて躯体６０に固定し、「Ｚ］字の他方の横棒の部分にネジ部材１２を設ければよい。尚、このようなベース部材１０Ａを他のレベル調整器具に適用することができる。
【００４１】
（実施の形態２）
実施の形態２は実施の形態１の変形である。実施の形態２において、固定部材は、実施の形態１と同様の構造を有する。一方、ベース部材８０は第３の構造を有する。実施の形態２のレベル調整器具の分解斜視図を図１１に示す。
【００４２】
実施の形態２における躯体は、略リップ溝形の断面形状を有し、第１のリップ部７１及び第２のリップ部７２を備えたバー状の躯体部材７０から構成されている。躯体部材７０の構造は、表面材取付部材５０と同様の構造とすることができるので、詳細な説明は省略する。尚、躯体部材７０は、例えばアンカーボルトとナットの組合せ７３によって、躯体６０に固定されている。
【００４３】
ベース部材８０は、躯体部材７０と係合する係合部材８１、及び、この係合部材８１に取り付けられたネジ部材８２から成る。金属製のネジ部材８２の頂部が、溶接により、係合部材８１の中央部に取り付けられている。レベル調整部材２０の構造は、実施の形態１の構造と同様とすればよいので、詳細な説明は省略する。
【００４４】
係合部材８１は、形状が略矩形の底面８４と、底面８４の対向する各辺から略垂直方向に延びる、対向した２つの側面８５と、底面８４の他の対向する各辺から略垂直方向に延びる、対向した２つの突出部８７から構成されている。かかる構造は、実質的に、固定部材２３の取付部の構造と同じである。即ち、係合部材８１の第１の側面８５及び第２の側面（図１１では見えない）のそれぞれには、躯体部材７０の第１のリップ部７１（図５の第１のリップ部５１と同じ構造である）及び第２のリップ部７２（図５の第２のリップ部５２と同じ構造である）と係合する凸部８６が設けられている。尚、突出部８７を第１の側面８５及び第２の側面と同じ構造としてもよい。
【００４５】
より具体的には、係合部材８１において、各凸部８６は、図４を参照して説明すると、上辺３２が下辺３１よりも短い略二等辺台形形状を有する第１の台形部３０と、第１の台形部３０の上辺３２から延在し、上辺４４が下辺４３よりも短い略二等辺台形形状を有する第２の台形部４０とから成る。そして、第２の台形部４０の下辺４１は、第１の台形部３０の上辺端部から側面底部に向かう方向に延び、躯体部材７０の第１のリップ部７１が、第１の側面８５及び第２の側面に設けられた第１の台形部３０の一方の側辺３３、及び、一方の側辺３３側の第１の台形部３０の上辺端部から延びる第２の台形部４０の下辺４１と係合し、躯体部材７０の第２のリップ部７２が、第１の側面８５及び第２の側面に設けられた第１の台形部３０の他方の側辺３４、及び、他方の側辺３４側の第１の台形部３０の上辺端部から延びる第２の台形部４０の下辺４２と係合する。第２の台形部４０の下辺４１，４２の延びる方向と水平線の成す角度θ2（図４参照）は、８度乃至２４度であることが好ましい。尚、第２の台形部４０の形状を言い換えれば、矩形若しくは等しい長さを有する台形（かかる矩形若しくは台形は下辺４３、上辺４４を有する）と、矩形の対向する２辺若しくは台形の側辺にそれぞれ接する三角形（三角形の２辺は、下辺４１，４２及び側辺４５，４６である）が組み合わされた形状（全体としては六角形）である。
【００４６】
実施の形態２の下地組工法においては、先ず、例えばアンカーボルトとナットの組合せ７３によって躯体部材７０を、例えばコンクリート壁から成る躯体６０に固定する。その後、係合部材８１における第１の側面８５及び第２の側面のそれぞれに設けられた凸部８６と、躯体部材７０の第１のリップ部７１及び第２のリップ部７２と係合させる。次いで、タッピング・スクリューやセルフ・ドリリング・スクリューといったスクリュー７４を用いて係合部材８１における突出部８７に躯体部材７０を止め、躯体部材７０が係合部材８１に対して移動しないようにする。
【００４７】
次に、ベース部材８０のネジ部材８２と、レベル調整部材２０のナット部材２１とを螺合させて、レベル調整部材２０をベース部材８０に取り付け、作業員が手でレベル調整治具材２２の外周部を把持し、レベル調整治具材２２を回動させることによって、ネジ部材８２の軸線方向に沿って固定部材２３を移動させ、固定部材２３とベース部材８０との間の間隔を調整する。尚、この調整は、一種の予備調整である。
【００４８】
その後、表面材取付部材５０を、固定部材２３に設けられた取付部に取り付ける。具体的には、固定部材２３における第１の側面２５及び第２の側面２５のそれぞれに設けられた凸部２６と、表面材取付部材５０の第１のリップ部５１及び第２のリップ部５２と係合させる。次いで、レベル調整治具材２２を回動させることによって、ネジ部材８２の軸線方向に沿って固定部材２３を移動させ、固定部材２３とベース部材８０との間の間隔を本格的に調整し、複数の表面材取付部材５０のレベルを出来る限り一致させる。その後、表面材取付部材５０に、例えば金属板から成る表面材６３をスクリュー等を用いて取り付けることで、下地組工法を完了させる。
【００４９】
尚、天井スラブ６０Ａの表面に取り付けられた鉄板から成る落下防止部材７５が躯体である場合に、実施の形態２のレベル調整器具及び下地組工法を適用した例を、図１２に、レベル調整器具の分解斜視図で示す。尚、天井スラブ６０Ａの表面に落下防止部材７５が取り付けられているので、天井スラブ６０Ａからの剥離物が室内に落下することを落下防止部材７５によって防止することができる。尚、例えばコンクリート壁の表面に落下防止部材が取り付けられた構造の躯体に対して、レベル調整器具を適用することもできる。
【００５０】
トンネルの内壁に相当する躯体に、実施の形態２のレベル調整器具及び下地組工法を適用した例を適用した例を、図１３に示す。この場合にあっては、トンネルの内壁に相当する躯体に、トンネルの走る方向に沿って躯体部材７０を平行に複数、取り付け、かかる躯体部材７０に係合部材８１を取り付ける。躯体部材７０の躯体への取り付けは、例えば、アンカーボルトとナットの組合せ７３を使用して行えばよい。そして、表面材取付部材５０の底部に、コルゲート加工されたステンレス鋼板から成る表面材６３をタッピング・スクリュー６４にて止める。尚、トンネルの内壁の表面に落下防止部材が取り付けられた構造の躯体に対して、レベル調整器具を適用することもできる。
【００５１】
以上、本発明を、発明の実施の形態に基づき説明したが、本発明はこれらに限定されるものではない。発明の実施の形態にて説明した各種のレベル調整器具や、その構成材料、躯体等、あるいは、下地組工法は例示であり、適宜変更することができる。
【００５２】
例えば、ベース部材１０Ｂを、躯体に固定されるプレート１１Ｂ、及び、このプレート１１Ｂに取り付けられたネジ部材１２から構成するとき、分解斜視図を図１４に示すように、プレート１１Ｂにはネジ山が切られた螺合部１３が設けられ、ネジ部材１２を螺合部１３を螺合させることによってネジ部材１２をプレート１１Ｂに取り付けることができる。ここで、ネジ山が切られた螺合部１３は、例えば、プレート１１Ｂに絞り加工を施した後、絞り加工部分にネジ山を切ることによって形成することができる。あるいは又、螺合部を、プレート１１Ｂに溶接されたナットやタップネジから構成することもできる。このような構造とすることで、固定部材２３とベース部材１０Ｂとの間の間隔を所望の間隔にするために、ネジ部材１２を容易に交換することができる。このようなベース部材１０Ｂの構造を、各種のベース部材に適用することができる。
【００５３】
レベル調整器具の変形例の一例の模式的な断面図を図１５に示し、組立前のレベル調整部材２０Ａの模式的な分解断面図を図１６に示し、組立前のレベル調整器具の模式的な分解斜視図を図１７に示す。このレベル調整部材２０Ａにおいては、ナット部材９０は、フランジ９１、及び、フランジ９１の下面から延びた管状部９２から構成されている。管状部９２の内面にはネジ山が切られている。管状部９２の外面がナット部材９０の外周部に該当する。レベル調整部材２０Ａのその他の構成は、実施の形態１にて説明したレベル調整部材２０の構造と同様である。尚、ベース部材を、実施の形態２にて説明したベース部材８０、あるいは、図９や図１４に示した構造のベース部材１０Ａ，１０Ｂとすることもできる。
【００５４】
ナット部材２１、レベル調整治具材２２及び固定部材２３の組立は、以下のようにして行うことができる。即ち、実施の形態１と同様に、中央部に突起部２２Ａが設けられたレベル調整治具材２２を準備する。突起部２２Ａには貫通孔２２Ｂが設けられており、貫通孔２２Ｂの内径と管状部９２の外径とは略等しい。更には、中央部に貫通孔２３’が設けられた固定部材２３を準備する。固定部材２３に設けられた貫通孔２３’の直径は、レベル調整治具材２２に設けられた突起部２２Ａの外径よりも大きい。そして、ナット部材９０の管状部９２に、固定部材２３の中央部に設けられた貫通孔２３’を挿入する。そして、ナット部材９０の管状部９２と、固定部材２３の中央部に設けられた貫通孔２３’との間の隙間に、レベル調整治具材２２の中央部に設けられた突起部２２Ａを挿入する。そして、ナット部材９０の管状部９２の他端をかしめることによって、管状部９２の一部９２Ａを突出させ、レベル調整治具材２２をナット部材９０の外周部（具体的には、管状部９２）に固定することができる。固定部材２３に設けられた貫通孔２３’の直径がレベル調整治具材２２に設けられた突起部２２Ａの外径よりも大きいので、固定部材２３は、ナット部材９０の外周部（具体的には、レベル調整治具材２２に設けられた突起部２２Ａ）に回動自在に取り付けられた状態となる。
【００５５】
尚、管状部９２の外周部に溝を形成し、かかる溝に「Ｃ」字状のリングを嵌合させることによっても、レベル調整治具材２２をナット部材９０の外周部（具体的には、管状部９２）に固定することもできる。
【００５６】
固定部材あるいは係合部材の各種の変形例を図１８〜図２０に示す。尚、以下においては、専ら、固定部材及び表面材取付部材についての説明を行うが、ベース部材と係合部材についても同様である。また、レベル調整部材の基本的な構成要素は、これまでに説明した各種の構成要素と同様とすることができる。
【００５７】
図１８は、固定部材２３Ａにおける凸部の部分を拡大した模式図である。更には、例えば、固定部材２３Ａと表面材取付部材５０とが係合した状態の拡大図を模式的に図１９に示す。この固定部材２３Ａにおいては、固定部材２３Ａの第１の側面２５Ａ及び第２の側面２５Ａのそれぞれの第２の台形部４０の下辺４１，４２と第１の台形部３０の上辺３２端部とが交差する領域よりも第２の台形部４０の内部にまで、第２の台形部４０の下辺４１，４２が延在している。尚、第２の台形部４０の内部にまで延在した第２の台形部４０の下辺４１，４２の部分を切欠部４７と呼ぶ。このような切欠部４７を設けることによって、表面材取付部材５０と固定部材２３Ａの係合を一層強固なものとすることができる。更には、固定部材２３Ａの第１の側面２５Ａ及び第２の側面２５Ａに設けられた第１の台形部３０の一方の側辺３３及び他方の側辺３４には、段差３３Ａ，３４Ａが設けられている。表面材取付部材５０の第１のリップ部５１及び第２のリップ部５２の内側に折れ曲がった部分５５，５６の一部分と、段差３３Ａ，３４Ａが係合する。これによって、表面材取付部材５０の第１のリップ部５１及び第２のリップ部５２と、第１の台形部３０の一方の側辺３３及び他方の側辺３４との係合が一層確実なものとなる。
【００５８】
固定部材２３Ｄあるいは係合部材の更なる変形例（第３の構造を有する固定部材、あるいは、第３の構造を有するベース部材）を図２０に示す。この固定部材２３Ｄにおいては、図４に示した凸部２６Ｄの外側のそれぞれに、図４に示した凸部を半分に分割した構造のもの２６Ｄ’が配設されている。このような構造にすることによって、固定部材２３の取付部においては、シングル野縁に相当する表面材取付部材、及び、ダブル野縁に相当する表面材取付部材のどちらも取り付けることが可能となる。
【００５９】
所望に応じて、躯体等の上、及び、躯体等と表面材取付部材との間、あるいは、躯体部材と表面材取付部材との間に断熱材６５を挿入してもよく、これによって高い結露防止効果を得ることができる。尚、この状態を、模式的に図７に示す。この場合、断熱材の固定に、ベース部材を構成するネジ部材を用いることができる。即ち、躯体等にベース部材を固定し、次いで、全面に断熱材を配置する、このとき、断熱材の表面からネジ部材の先端が突出するようにする。これによって、ネジ部材にレベル調整部材を構成するナット部材を螺合させたとき、断熱材をレベル調整治具材によって押さえることができ、断熱材を躯体等に対して容易に固定することができる。このように、レベル調整器具を断熱材押え治具を兼用させることによって、施工コストの低減を図ることができる。
【００６０】
【発明の効果】
本発明においては、ナット部材の外周部に固定されたレベル調整治具材を回動させるだけで、容易に、しかも、複数の表面材取付部材のレベル出しを行うことができる。従って、作業員の熟練が不要であり、しかも、工期の短縮を図ることが可能となる。しかも、ミリメートル単位での表面材取付部材のレベル出しを行うことができるので、化粧仕上材の幅広い自由な選択が可能となり、例えば、光沢性の強い表面材（例えば、カラーアルミニウムパネル、ステンレス鋼鏡面仕上げ材、カラー鋼板）の施工を容易に、且つ、短時間で行うことができる。
【００６１】
しかも、本発明における固定部材としたり、あるいは又、係合部材を第３の構造を有する係合部材とすれば、固定部材と表面材取付部材との間、係合部材と躯体部材との間に高い係合力を得ることができる。その結果、従来、使用されていた分野だけでなく、例えばトンネル内やコンクリート製高架橋、コンクリート製外壁を有する建築物等におけるコンクリート片やモルタル片の崩落を防止するための被覆材である表面材を確実に、しかも、短時間で、躯体に取り付けることが可能となる。更には、固定部材への表面材取付部材の取り付け、係合部材への躯体部材の取り付けをワンタッチで行うことができ、加えて、完全乾式工法であるが故に、工期の短縮化を図ることができるし、不燃・無溶接工法とすることができるが故に、安全性が高い。更には、完成後の躯体の補修を容易に、且つ、短期間で行うことが可能である。また、躯体等と表面材との間に断熱材を挿入することが可能であり、高い結露防止効果を得ることができる。更には、例えば、トンネル内で漏出してきた地下水等を被覆材である表面材で受けることができ、躯体に面した表面材の表面上を伝わり、あるいは流れる地下水等を容易に外部に排出することができる。
