Description

【０００１】
【発明の属する技術分野】
本発明は、建築物外壁の施工において、壁板材を構造材に固着するのに建築構造物の内部より行うことができるとともに簡易且つ迅速なる施工作業とし、外部に外壁施工用の仮設用足場等を不要とすることができる壁体取付構造に関する。
【０００２】
【従来の技術】
従来より、複数の建築用板を壁材として、並設する建築物外壁の施工では、鉄骨構造体における上下方向に水平且つ適宜の間隔をおいて配置された胴縁等の構造材に複数の建築用板を並設して壁等の壁体を施工する。この種の施工では、先ず、建築構造物の外壁施工のさらに外側箇所に仮設足場を施工し、作業員はその仮設足場を利用して、建築用板を構造材に取り付ける作業を行っていた。この仮設足場は、外壁施工の完後に解体する。
【０００３】
【発明が解決しようとする課題】
上述したように、建築構造物の外壁施工は、建築用板を建築構造物の外側より構造材に当てて、仮設足場を施工することが必要である。その仮設足場は、建築構造物の外周を囲むように施工する必要がある。そして、構造材に建築用板を配置し、該建築用板と構造材とをボルト・ナット或いはフックボルト等の固着具を介して、固着するものである。
【０００４】
さらに、建築用板にて外壁の施工が完了すると、その仮設足場を解体することになる。このように、建築構造物の外壁の施工には、新たに仮設足場を必要とすることとなり、そのために、仮設足場の施工専門の業者が必要となる。これは、仮設足場の組立及び解体の作業による、施工時間及び施工費を必要とし、建築構造物全体の施工時間及び施工費に加わってゆくこととなる。
【０００５】
また、建築構造物の外壁施工は、常に建築構造物の外側から行うものであるために、特に天候に左右されやすく、雨天時が続くと、工期が大幅に延びることもありうる。このような事情から、建築構造物の外壁施工において、建築用板を構造材に固着するのに、建築構造物の内部側より行うことが可能となる構造及び施工法が期待されている。
【０００６】
【課題を解決するための手段】
そこで、発明者は上記課題を解決すべく、鋭意，研究を重ねた結果、本発明を、断面を略台形の膨出部を有する主板の幅方向の一端側の裏面側から内方に向かって略水平状の第１重合縁を形成し，主板の他端側より幅方向外方に向かって略水平状の第２重合縁を形成した壁板材と、フランジ状部を有する構造材と、壁板材同士の接合部分を前記フランジ状部に押圧しつつ固定する押え部とからなる壁体取付構造において、前記押え部に隣接し且つ下端に係止屈曲端縁を形成し上端に受け板片を形成した当て板部と，該当て板部に対向し且つ当て板部と上下方向にずれた状態で固着具にて締め付自在とした締付部材とを有する壁板材固定具を設け、前記構造材のフランジ状部に複数の壁板材を配置し、フランジ状部の下端を係止屈曲端縁で係止してフランジ状部の上方箇所を固着具を介して当て板部と締付部材とで挟持し、前記受け板片にて前記締付部材の上方側が受け止められ該締付部材と前記当て板部とが略平行状に対向して前記押え部にて壁板材同士の第２重合縁と第１重合縁との重合箇所をフランジ状部に固定してなる壁体取付構造としたことにより、建築構造物の外壁の施工において、壁板材を構造材に固着するのに建築構造物の内部側で簡易且つ迅速に行なうことができ、上記課題を解決したものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。本発明の壁体は、主に、壁板材Ａ，構造材４，及び壁板材固定具Ｂから構成される〔図１，図２（Ａ）等参照〕。その壁板材として使用する壁板材Ａは、図５（Ａ），（Ｂ）に示すように、主板１の幅方向の一方側に第１重合縁２が形成され、他方側には第２重合縁３が形成されている。その壁板材Ａの主板１は、一つ又は複数の膨出部１ａが形成されている。
【０００８】
該膨出部１ａは、その断面形状が図５（Ｂ）に示すように、略偏平台形状であり、その頂部１ａ_１は平坦状である。その膨出部１ａが壁板材Ａの幅方向に沿って形成されている。図５（Ａ），（Ｂ）の実施例においては、主板１は、二つの膨出部１ａ，１ａから構成されている。また、膨出部１ａが一つのみからなる主板１の場合には、主板１の略全体が膨出部１ａとして形成される。
【０００９】
その壁板材Ａの幅方向一端には、第１重合縁２が形成され、幅方向他端には第２重合縁３がそれぞれ形成されている。その第１重合縁２は、膨出部１ａの端部から裏面側より内方に向かって水平状に形成され、その端縁は折返し形成されることもある。即ち、膨出部１ａの頂部１ａ_１と略平行となる。
【００１０】
そして、隣接する壁板材Ａ，Ａは、対向する第２重合縁３内に第１重合縁２を重合し、該重合箇所を後述する壁板材固定具Ｂを介して構造材４に固定する。第１重合縁２の端縁が折り返されてヘアピンカーブ状箇所が形成されることもある。また、第２重合縁３は、前記第１重合縁２とは幅方向の反対側で且つ壁板材Ａの幅方向に伸びるようにして形成されている。
【００１１】
隣接する壁板材Ａ，Ａ同士の第２重合縁３と第１重合縁２との重合箇所は、膨出部１ａの裏面側にて構成される。即ち、第１重合縁２と第２重合縁３との重合箇所と膨出部１ａの頂部１ａ_１との間には作業に好適なスペースが形成され、該スペースを利用して壁板材固定具Ｂを後述する構造材４に装着することができる〔図４（Ａ），（Ｂ）参照〕。
【００１２】
次に、構造材４は、建築構造物の鉄骨構造における胴縁等として使用され、これに使用される鋼材としては、溝形鋼或いは等辺（又は不等辺）山形鋼等の形鋼が使用される。その他に、Ｉ形鋼，Ｈ形鋼等が使用されることがある。その構造材４のフランジ状部４ａは、構造材４の長手方向に沿った平坦状板部分のことである。
【００１３】
例えば、図１，図３（Ｂ）に示す溝形鋼の場合には、フランジ状部４ａに該当する部分はウェッブ部分の幅方向両側端に形成された立上り部分のことをいう。また、Ｉ形鋼，Ｈ形鋼の場合も、同様に前記フランジ状部４ａはウェッブの幅方向両側端に形成された立上り部分のことをいう。等辺（又は不等辺）山形鋼の場合には、フランジ状部４ａは直交するいずれかの平坦状板部分のことをいう。
【００１４】
次に、壁板材固定具Ｂは、図２（Ｂ），（Ｃ）等に示すように、装着部Ｂ_１と押え部５から形成されている。該押え部５は、覆い部５ａと押付け部５ｂとから構成される。その覆い部５ａは、断面略門形状をなし、前記壁板材Ａ，Ａ同士の第２重合縁３と第１重合縁２との重合箇所を被覆することができる。また、押付け部５ｂは、壁板材Ａ，Ａ同士の第２重合縁３と第１重合縁２との重合箇所をフランジ状部４ａに押圧する役目をなす。
【００１５】
その装着部Ｂ_１は、当て板部６、クリップ状板７、係止屈曲端縁６ａから形成されており、当て板部６の上端にクリップ状板７が形成され、下端に係止屈曲端縁６ａが形成されている。当て板部６は、平坦状をなし、フランジ状部４ａに当接することができるようになっている。
【００１６】
そのクリップ状板７は、板状をなし、当て板部６に対して略対向するようにして当て板部６の上端箇所から屈曲部分を介して一体的に形成されたものである。また、クリップ状板７は当て板部６に対して、弾性を有するようにしていることが好ましい。そのクリップ状板７と前記当て板部６とにより前記構造材４のフランジ状部４ａを挟持状態にするものである。また、クリップ状板７に弾性を有するものとした場合には、当て板部６とクリップ状板７とがフランジ状部４ａを弾性的に押圧するようにして挟持固定することができる。
【００１７】
また、当て板部６の下端には係止屈曲端縁６ａが形成され、該係止屈曲端縁６ａがフランジ状部４ａの下端に係止し、壁板材固定具Ｂを構造材４に支持固定することができるようになっている。係止屈曲端縁６ａは、当て板部６の下端より僅かに上方に傾斜するように形成されることもある。このように係止屈曲端縁６ａが傾斜して形成された場合には、構造材４に係止固定したときに、係止屈曲端縁６ａが構造材４のフランジ状部４ａ下端を適正な押圧力にて弾性的な固定とすることができる。
【００１８】
次に、壁板材固定具Ｂの第２実施例を説明する。該実施例では、図７に示すように、装着部Ｂ_１が当て板部６と、締付部材９とから構成されるものである。該締付部材９は、前記当て板部６とは別部材として形成されたものである〔図７，図８（Ｂ）及び図９（Ａ）等参照〕。
【００１９】
その締付部材９は、締付板部９ａと押圧部９ｂとから形成され、締付板部９ａは、略長方形状板として形成され、該締付板部９ａの幅方向両側より押圧部９ｂが形成されている（図７参照）。該押圧部９ｂは締付板部９ａに対して略直角に形成されている。
【００２０】
その押圧部９ｂは、前記フランジ状部４ａの内側に当接する〔図９（Ａ），（Ｂ）参照〕。押圧部９ｂの押圧面は、傾斜押圧面９ｂ_１が形成されることもあり、この傾斜押圧面９ｂ_１の勾配θは、フランジ状部４ａの勾配に略等しく形成される。即ち、構造材４として使用する溝形鋼やＩ形鋼等のフランジ状部４ａは、内壁面側に勾配が設けられているので、押圧部９ｂに傾斜押圧面９ｂ_１を形成することで、当て板部６と締付部材９とが略平行に対向させることができるようにしたものである。
【００２１】
これによって、構造材４が溝形鋼やＩ形鋼等のフランジ状部４ａの内面側が傾斜面となっている場合にその当接状態を良好とし、ひいては装着強度を強固にすることができる。その当て板部６と締付部材９とは、固着具１０を介して着脱自在に構成されている。
【００２２】
該固着具１０は、具体的にはボルト１０ａ，ナット１０ｂ及び座金１０ｃから構成されたものである。前記当て板部６と締付部材９には、固着具１０のボルト１０ａの軸部が貫通する連結用の位置調整孔６ｂ及び９ｃが形成されている。当て板部６と締付部材９のそれぞれ位置調整孔６ｂ及び９ｃの少なくともいずれか一方を長孔とする。或いは両方とも長孔とすることが好ましい。
【００２３】
壁板材固定具Ｂを構造材４のフランジ状部４ａに装着するときには、当て板部６と締付部材９とが上下方向にずれて固着具１０により締付固定される。当て板部６と締付部材９との上下方向の相互のズレた状態にするには、前記位置調整孔６ｂ及び９ｃの少なくとも一方を長孔とすることで容易にできる。そして、前記固着具１０を締め付けて、その締付部材９側が当て板部６よりも高い位置になるようにセットされる〔図９（Ａ）参照〕。そして、フランジ状部４ａの内側に締付部材９が位置し、フランジ状部４ａの外側に当て板部６が配置され、フランジ状部４ａを挟持する。
【００２４】
当て板部６には、第１実施例と同様にその下端に係止屈曲端縁６ａが形成されており、さらに上端には、前記締付部材９を受けるための受け板片６ｃが形成されている。該受け板片６ｃは、締付部材９を固着具１０を介して当て板部６に締め付けたときに、その締付部材９の上方側を受け止め、締付部材９が当て板部６に略平行状に対向することができるようにする役目をなすものである〔図９（Ａ）参照〕。
【００２５】
構造材４は、本発明において、通常，フランジ状部４ａが上向きとなるようにして施工されることになるが、第２実施例の壁板材固定具Ｂを使用する場合には、図９（Ｃ）に示すように、構造材４は、フランジ状部４ａが下向きとなるようにして配置してもよい。この場合には、係止屈曲端縁６ａが上方に位置して、構造材４のウェッブ状部の幅方向端部に係止される。
【００２６】
【作用】
まず、構造材４のフランジ状部４ａに壁板材Ａを配置し、隣接する壁板材Ａ，Ａ同士の第１重合縁２と第２重合縁３とを重合させる。このとき第２重合縁３がフランジ状部４ａの外面側に当接する。その隣接する壁板材Ａ，Ａ同士の重合部分を壁板材固定具Ｂの押え部５にて覆うように押さえつつ、当て板部６とクリップ状板７にてフランジ状部４ａの挟持しながら、その上端部箇所をハンマー等の工具で打ち込む。
【００２７】
これによって、クリップ状板７は、当て板部６から一旦，離間しながら、その係止屈曲端縁６ａがフランジ状部４ａの下端に達し、係止屈曲端縁６ａがフランジ状部４ａの下端箇所に係止完了するとともに、クリップ状板７は弾性的な復元力で、もとの位置に戻り、強固なる構造材４への固定とすることができる。図４（Ａ），（Ｂ）は、上述した構造材４のフランジ状部４ａに装着する工程において、その途中の段階を示したものである。
【００２８】
また、第２実施例の壁板材固定具Ｂを使用する場合について説明する。壁板材固定具Ｂの当て板部６と締付部材９とは、固着具１０を緩めて、両者の間隔を拡げた状態で当て板部６と締付部材９とでフランジ状部４ａを挟持する。このとき、当て板部６の下端に形成した係止屈曲端縁６ａがフランジ状部４ａの下端に係止させておくと作業性が良くなる。
【００２９】
そして、そのまま固着具１０を締め付けることで、当て板部６と締付部材９とがフランジ状部４ａを締付力にて挟持し、構造材４への装着を完了する。また、締付部材９の押圧部９ｂに形成した傾斜押圧面９ｂ₁ は、溝形鋼等でフランジ状部４ａの内面側に勾配が設けられている場合の使用に好適である〔図９（Ａ）参照〕。上記の施工作業は、建築物の内側から施工する（図１０参照）。また、上述したように、前記構造材４のフランジ状部４ａに複数の壁板材Ａ，Ａ，…を配置し、壁板材固定具Ｂの当て板部６とクリップ状板７にてフランジ状部４ａの上方を挟持且つ係止屈曲端縁６ａをフランジ状部４ａ下端に係止し、その押え部５にて壁板材Ａ，Ａ同士の第２重合縁３と第１重合縁２との重合箇所をフランジ状部４ａに固定してなる壁体取付構造としたことにより、建築工事において外壁の施工を内部側より行なうことができるし、特に壁板材固定具Ｂの構造材４への装着も簡易且つ迅速に行なうことができる。すなわち、壁板材固定具Ｂは、壁板材Ａ，Ａ同士の接合部分を前記フランジ状部４ａに押圧しつつ固定する押え部５と，該押え部５に隣接し且つ下端に係止屈曲端縁６ａを形成した当て板部６と，該当て板部６の上端から前記係止屈曲端縁６ａ側に折返し状に形成したクリップ状板７とから構成されたものである。そして、壁板材固定具Ｂをフランジ状部４ａに係止する場合には、当て板部６とクリップ状板７とで挟持しつつ係止屈曲端縁６ａをフランジ状部４ａの下端に係止することにより係止固定することができる。これによって、壁板材固定具Ｂは、溶接手段或いはボルト・ナット等の固着手段によることなく、略瞬間的に構造材４に装着することができるものであり、また押え部５を備えているので、壁板材Ａ，Ａ同士の接合箇所と壁板材固定具Ｂとを略同時に構造材４に装着固定することができ、施工効率を良好にすることができる。
【００３０】
【発明の効果】
請求項１の発明は、断面を略台形の膨出部１ａを有する主板１の幅方向の一端側の裏面側から内方に向かって略水平状の第１重合縁２を形成し，主板１の他端側より幅方向外方に向かって略水平状の第２重合縁３を形成した壁板材Ａと、フランジ状部４ａを有する構造材４と、壁板材Ａ，Ａ同士の接合部分を前記フランジ状部４ａに押圧しつつ固定する押え部５とからなる壁体取付構造において、前記押え部５に隣接し且つ下端に係止屈曲端縁６ａを形成し上端に受け板片６ｃを形成した当て板部６と，該当て板部６に対向し且つ当て板部６と上下方向にずれた状態で固着具１０にて締め付自在とした締付部材９とを有する壁板材固定具Ｂを設け、前記構造材４のフランジ状部４ａに複数の壁板材Ａ，Ａ，…を配置し、フランジ状部４ａの下端を係止屈曲端縁６ａで係止してフランジ状部４ａの上方箇所を固着具１０を介して当て板部６と締付部材９とで挟持し、前記受け板片６ｃにて前記締付部材９の上方側が受け止められ該締付部材９と前記当て板部６とが略平行状に対向して前記押え部５にて壁板材Ａ，Ａ同士の第２重合縁３と第１重合縁２との重合箇所をフランジ状部４ａに固定してなる壁体取付構造としたことにより、建築工事において外壁の施工を内部側より行なうことができ、しかもその施工を簡易且つ迅速に行なうことができ、且つ壁板材固定具Ｂは、寸法が多少異なる種々の構造材４に対応して、装着することができる。
【００３１】
即ち、壁板材Ａ，Ａ同士の接合は裏面側で可能であるために、その接合箇所も壁板材Ａ，Ａ同士の裏面側に存在することになる。また、壁板材固定具Ｂは、構造材４のフランジ状部４ａを上方及び下端に係止して固定するもので、非溶接或いはボルトレスで構造材４に固定することができる。それゆえに、建築物の内部側より複数の壁板材Ａ，Ａ，…を壁板材固定具Ｂを介して構造材４に固定することができ、その施工も簡易且つ迅速に行なうことができる（図１０参照）。
【００３２】
さらに、請求項１の発明では、建築工事において外壁の施工を内部側より行なうことができるし、特に壁板材固定具Ｂの構造材４への装着も簡易且つ迅速に行なうことができる。
【００３５】
また、請求項１の発明では、壁板材固定具Ｂは、寸法が多少異なる種々の構造材４に対応して、装着することができる。
【００３６】
上記効果を詳述すると、当て板部６は、下端に係止屈曲端縁６ａを形成し、締付部材９は、当て板部６とは別部材で、固着具１０を介して当て板部６に対向して締付け自在に連結することができる。また、当て板部６と締付部材９とは、上下方向にずれた状態で接合することができるので、フランジ状部４ａの高さが多少異なるいくつかの構造材４であっても、その違いに対応してフランジ状部４ａに装着することができ、これによって施工性を良好にしている。

The wall body of the present invention mainly includes a wall plate material A, a structural member 4, and a wall plate material fixing tool B (see FIGS. 1 and 2A). As shown in FIGS. 5A and 5B, the wall plate material A used as the wall plate material has a first overlapped edge 2 formed on one side in the width direction of the main plate 1 and a second overlapped edge on the other side. An edge 3 is formed. The main plate 1 of the wall plate material A is formed with one or a plurality of bulging portions 1a.
[0008]
Evagination portion 1a, as the sectional shape shown in FIG. 5 (B), a roughly flat trapezoidal, its top 1a ₁ is flat. The bulging portion 1a is formed along the width direction of the wall plate material A. In the embodiment shown in FIGS. 5A and 5B, the main plate 1 is composed of two bulging portions 1a. In the case where the main plate 1 includes only one bulging portion 1a, substantially the entire main plate 1 is formed as the bulging portion 1a.
[0009]
A first overlapped edge 2 is formed at one end in the width direction of the wall plate material A, and a second overlapped edge 3 is formed at the other end in the width direction. The first overlapped edge 2 is formed horizontally from the end of the bulging portion 1a toward the inside from the back side, and the edge may be folded back. That is, substantially parallel to the top portion 1a ₁ of the bulging portion 1a.
[0010]
Then, the adjacent wall plate materials A, A overlap the first overlapped edge 2 in the opposed second overlapped edge 3, and fix the overlapped portion to the structural material 4 via the wall plate material fixing tool B described later. The edge of the first overlapped edge 2 may be folded back to form a hairpin curved portion. Further, the second overlapped edge 3 is formed on the opposite side of the first overlapped edge 2 in the width direction and so as to extend in the width direction of the wall plate material A.
[0011]
The overlapping portion of the second overlapping edge 3 and the first overlapping edge 2 between the adjacent wall plate materials A, A is formed on the back surface side of the bulging portion 1a. That is, the first polymerization edge 2 between the top portion 1a ₁ of the polymerization portion and bulged portion 1a of the second polymerization edge 3 suitable space is formed in the work, wallboard fixture utilizing the space B can be mounted on a structural member 4 described later (see FIGS. 4A and 4B).
[0012]
Next, the structural material 4 is used as a rim or the like in a steel structure of a building structure. As a steel material used for this, a section steel such as a channel steel or an equilateral (or unequal side) angle iron is used. You. In addition, I-beams, H-beams, and the like may be used. The flange portion 4a of the structural material 4 is a flat plate portion along the longitudinal direction of the structural material 4.
[0013]
For example, in the case of the channel steel shown in FIGS. 1 and 3 (B), the portion corresponding to the flange-shaped portion 4a means a rising portion formed at both ends in the width direction of the web portion. Similarly, in the case of I-shaped steel and H-shaped steel, the flange-shaped portion 4a also refers to a rising portion formed at both ends in the width direction of the web. In the case of equilateral (or unequal-side) angle iron, the flange-like portion 4a refers to any of the orthogonal flat plate portions.
[0014]
Next, wallboard fastener B is FIG. 2 (B), is formed from such, mounting portion B ₁ and the pressing portion 5 shown in (C) or the like. The presser 5 is composed of a cover 5a and a presser 5b.
