【発明が解決しようとする課題】
上記従来の仮設テントでは、アーチ形フレーム間に張設される帯状シートを緊張させるのに、隣合うアーチ形フレームを連結する棒状部材を、入れ子式に嵌合された雄部材と雌部材とにより伸縮可能に構成して、この棒状部材を適宜に伸張させることにより、帯状シートを伸張させるようにしているが、棒状部材を伸張するには、アーチ形フレームを移動させる必要があるため、作業が非常に困難となっていた。
【０００５】
本発明は、上記の問題に鑑み、アーチ形フレーム間に張設される帯状シートを簡単に緊張させることができるようにした仮設テントを提供することを目的とする。
【０００６】
【課題を解決するための手段】
請求項１に係る発明は、夫々シート耳部保持手段２を備えた複数のアーチ形フレーム１を所要間隔おきに並設し、帯状シート３の両耳部４，４を隣合うアーチ形フレーム１，１のシート耳部保持手段２，２により保持して帯状シート３を張設するようにした仮設テントにおいて、隣合うアーチ形フレーム１，１のシート耳部保持手段２，２によって両耳部４，４を保持された帯状シート３の耳部４，４近傍を上から押え付けて帯状シート３を緊張させるためのシート緊張手段５をアーチ形フレーム１に設けてなり、該シート緊張手段５は、前記帯状シート３の耳部４，４近傍を上から押え付ける両側一対の押え棒１７，１７と、両押え棒１７，１７をつなぐ複数の略下向きコ字状の連結金具１８とからなり、各コ字状連結金具１８は、その両端部が両押え棒の夫々上側面部に固着されていて、アーチ形フレーム１の上部側に取り付けられるようになっていることを特徴とする。
【０００８】
請求項２は、請求項１に記載の仮設テントにおいて、各アーチ形フレーム１には、前記シート緊張手段５の押え棒１７を上から押え付ける複数の押え棒押え金具２５が取り付けられるようになっていることを特徴とする。
【０００９】

【００１０】
【発明の実施の形態】
図１は本発明に係る仮設テントを示す正面図、図２は平面図である。図３は、帯状シート３の耳部４，４をシート耳部保持手段２によって保持しただけの状態を示す断面図である。また、図４の(a) は、シート耳部保持手段２で耳部４を保持された帯状シート３をシート緊張手段５によって緊張させた状態の帯状シート３の一部を示す拡大横断面図であり、(b) は同状態の仮設テントの帯状シート３の全体を概略示す横断面図である。図５は、シート緊張手段５の押え棒１７の所要部を押え棒押え金具２５によって上から押え付けた状態を示す図４の(a) と同様な拡大横断面図である。
【００１１】
この仮設テントは、夫々シート耳部保持手段２を備えた複数のアーチ形フレーム１を、当該アーチ形フレーム１と直交する方向へ所要間隔おきに並設すると共に、隣合うアーチ形フレーム１，１同士を複数の水平支持部材６により連結し、そして帯状シート３の両耳部４，４を隣合うアーチ形フレーム１，１のシート耳部保持手段２により保持して、帯状シート３を隣合うアーチ形フレーム１，１間に張設した後、隣合うアーチ形フレーム１，１のシート耳部保持手段２によって両耳部４，４を保持された帯状シート３の耳部４近傍を、シート緊張手段５によって上から押え付けることにより、帯状シート３を緊張させたものである。尚、水平支持部材６の端部はアーチ形フレーム１の下部フランジ９に対しボルト止め又は溶接によって固定される。
【００１２】
各アーチ形フレーム１は、図１に示すように正面視略々山形に形成されたもので、当該アーチ形フレーム１の頂部Ｏから両側に直線状に傾斜した直線状フレーム部材１ａ，１ａと、両直線状フレーム部材１ａ，１ａに夫々接続された曲線状フレーム部材１ｂ，１ｂとからなり、両直線状フレーム部材１ａ，１ａは上端部同士がアーチ形フレーム１の頂部Ｏで接合されている。尚、アーチ形フレーム１は、図示のような山形に限るものではなく、半円状、三角形状、多角形状等に形成されてもよい。
【００１３】
直線状及び曲線状の各フレーム部材１ａ，１ｂは、図３に示すように、ウェブ７と上下両フランジ８，９とで断面略Ｉ字形を成すアルミ押出し型材からなる。帯状シート３は、ＰＶＣ被覆ナイロン、ポリエステル、ガラス繊維、テフロン（登録商標）、ケブラー（登録商標）等の繊維材料を使用して織られた織物からなるもので、防水処理ならびに防炎処理が施されている。帯状シート３の耳部４には抜け止め材１０が設けられており、この抜け止め材１０は、断面円形で可撓性を有するロープ状のもので、図３に例示するように帯状シート３の耳部４に巻き込まれた状態で帯状シート３の耳部４に取り付けられる。
【００１４】
シート耳部保持手段２は、図３に示すようにアーチ形フレーム１の上部フランジ８に当該フレーム１の全長に亘って取り付けられたカバー部材１１からなり、このカバー部材１１は、アーチ形フレーム１の上部フランジ８と同じ幅を有し、幅方向両側端部に下向きコ字状のチャンネル部１１ａ，１１ａを形成すると共に、両チャンネル部１１ａ，１１ａの間に上向きコ字状のチャンネル部１１ｂを形成したアルミ押出し型材からなる。
【００１５】
また図３に示すように、アーチ形フレーム１の上部フランジ８には上面の左右両端部側に溝８ａ，８ａが形成され、その各溝８ａと、上部フランジ８に取り付けられたカバー部材１１の各下向きコ字状チャンネル部１１ａとの間に、抜け止め材挿通案内路１２がアーチ形フレーム１の長手方向全域に形成されると共に、この抜け止め材挿通案内路１２の外側端部にはシート挿通用間隙部１３がアーチ形フレーム１の長手方向全域に形成される。
【００１６】
また、アーチ形フレーム１の上部フランジ８には左右両溝溝８ａ，８ａの間の平坦面部８ｏに、断面略々逆Ｔ字状のボルト頭嵌合溝１４がアーチ形フレーム１の長手方向全域に形成され、このボルト頭嵌合溝１４には、カバー部材１１を上部フランジ８に取り付けるボルト１５の頭１５ａが回転不能でスライド可能に嵌合される。カバー部材１１をアーチ形フレーム１の上部フランジ８に取り付ける時には、上部フランジ８のボルト頭嵌合溝１４に所要数個のボルト１５の頭１５ａを嵌合しておいて、各ボルト１５を適宜スライドさせながら、カバー部材１１の上向きコ字状チャンネル部１１ｂに所要間隔おきに設けられたボルト挿通孔（図示せず）に挿通した後、ナット１６を締め付けて、カバー部材１１のチャンネル部１１ｂの下面側を上部フランジ８の幅方向中央平坦面部８ｏに固定する。
【００１７】
図４には、シート耳部保持手段２で両耳部４，４を保持された帯状シート３の耳部４の近傍を上から押え付けて帯状シート３を緊張させるシート緊張手段５が示されている。このシート緊張手段５は、帯状シート３の耳部４に近い部分を上から押え付ける両側一対の押え棒１７，１７と、両押え棒１７，１７をつなぐ複数の略下向きコ字状の連結金具１８とからなるもので、各コ字状連結金具１８の両端が両押え棒１７，１７の夫々上側面部に固着されている。
【００１８】
このシート緊張手段５は、直線状のフレーム部材１ａに設けられる直線形シート緊張手段５ａと、曲線状のフレーム部材１ｂに設けられる曲線形シート緊張手段５ｂとからなる。直線形シート緊張手段５ａは、図７に示すように、直線状フレーム部材１ａに対応する直線状の一対の押え棒１７，１７と、両押え棒１７，１７をつなぐ複数の略下向きコ字状の連結金具１８とからなり、また曲線形シート緊張手段５ｂは、図８に示すように、曲線状フレーム部材１ｂに対応する曲線状の一対の押え棒１７，１７と、両押え棒１７，１７をつなぐ複数の略下向きコ字状の連結金具１８とからなるものである。
【００１９】
押え棒１７は、丸形鋼管からなるもので、直線形シート緊張手段５ａの場合には丸形鋼管を直線状のままで使用され、また曲線形シート緊張手段５ｂの場合には丸形鋼管を曲線状に曲げ加工したものである。連結金具１８は、直線形シート緊張手段５ａの場合も曲線形シート緊張手段５ｂの場合も同じものが使用され、図４、図７及び図８から分かるように、比較的厚めの鋼板材をプレス加工して、両押え棒１７，１７のピッチに相当する長さを有する上板部１８ａと、この上板部１８ａの両端から夫々垂直下向きに折曲延設された所定高さの脚板部１８ｂ，１８ｂとからなる正面視略々Ｍ字状に形成されたもので、上板部１８ａの中央部は略Ｕ字状の陥没部１８ｏを形成し、この陥没部１８ｏにボルト挿通孔１９が設けられ、また上板部１８ａと各脚板部１８ｂとのコーナー部には補強部片２０が取り付けてある。そして、両脚板部１８ｂ，１８ｂの夫々下端が両押え棒１７，１７の夫々上側面部に溶接により一体的に固着されている。
【００２０】
上記のように構成されるシート緊張手段５は、シート耳部保持手段２と同様にアーチ形フレーム１の上部フランジ８に取り付けられる。この取付けの際には、上部フランジ８のボルト頭嵌合溝１４に所要数個のボルト２１の頭２１ａを嵌合しておいて、各ボルト１５を、シート耳部保持手段２のカバー部材１１を貫通させて上方に突出させた状態でその突出部にスペーサ用ナット２３を螺合した後、このボルト１５を連結金具１８のボルト挿通孔１９に挿通して、その挿通端部に締付用ナット２４を螺合し、この締付用ナット２４を締め付けることによって、連結金具１８を、カバー部材１１及びスペーサ用ナット２３を介してアーチ形フレーム１の上部フランジ８に固定し、図４に示すような状態とする。
【００２１】
図５は、上記シート緊張手段５の連結金具１８と連結金具１８との中間に取り付けられる押え棒押え金具２５の取付状態を示す。この押え棒押え金具２５は、シート緊張手段５の押え棒１７を隣合う連結金具１８，１８の中間位置で上から押え付けるためのもので、シート緊張手段５の連結金具１８と全く同じ構造の下向きコ字状金具本体２６と、この下向きコ字状金具本体２６の両端に取り付けられて、シート緊張手段５の両押え棒１７，１７に上方より係嵌する係嵌部材２７，２７とからなる。この金具２５は、構造が簡単であるため、製作が容易であると共に、金具本体２６がシート緊張手段５の押え棒１７と同じ構造であることから、金具本体２６をその押え棒１７と同じ行程で製作でき、従って製作コストをより安くできる。
【００２２】
この押え棒押え金具２５の取付けは、シート緊張手段５と同じ様に、アーチ形フレーム１の上部フランジ８のボルト頭嵌合溝１４に所要数個のボルト２８の頭２８ａを嵌合しておいて、各ボルト２８を、シート耳部保持手段２のカバー部材１１を貫通して上方に突出させた状態でその突出部にスペーサ用ナット２９を螺合した後、このボルト２８を金具本体２６のボルト挿通孔（図示せず）に挿通してその挿通端部に締付用ナット３０を螺合し、この締付用ナット３０を締め付けることによって、金具本体２６をカバー部材１１及びスペーサ用ナット２９を介してアーチ形フレーム１の上部フランジ８に固定し、図５に示すような状態とする。
【００２３】
図９は、シート耳部保持手段２を備えたアーチ形フレーム１の拡大正面図、図１０の(a) は図９の矢印Ｂで囲まれた部分の拡大図、同図の(b) は(a) の矢印Ｄから見た側面図、同図の(c) は頂部連結部材３１を示す正面図、同図の(d) は同連結部材３１の側面図である。また図１１の(a) は図９の矢印Ｃで囲まれた部分の拡大図、(b) は同部分の側面図である。各アーチ形フレーム１は、図１に示すように正面視略々山形に形成されていて、当該アーチ形フレーム１の頂部Ｏから両サイドへ直線状に傾斜した直線状フレーム部材１ａ，１ａと、両直線状フレーム部材１ａ，１ａに夫々連結された曲線状フレーム部材１ｂ，１ｂとからなるもので、両直線状フレーム部材１ａ，１ａの上端部同士がアーチ形フレーム１の頂部Ｏで連結されている状態を図１０に示し、直線状フレーム部材１ａと曲線状フレーム部材１ｂとの連結状態を図１１に示す。
【００２４】
両直線状フレーム部材１ａ，１ａの上端部同士は、図１０に示すように、山形に形成された両側一対の頂部連結部材３１，３１によって連結する。即ち、両直線状フレーム部材１ａ，１ａを双方から山形に突き合わせ、その対向端部を両側一対の頂部連結部材３１，３１で挟み付けて、ボルト３２により締結し、そして連結部分の下部側には、図１０の(a) に示すように下部合掌金具３３を取り付ける。各頂部連結部材３１には、同図の(c) にも示すようにガイドローラ３４が装備されている。
【００２５】
このガイドローラ３４は、両直線状フレーム部材１ａ，１ａの上端突き合わせ部分に開口部分４０ができて、シート耳部保持手段２のカバー部材１１にアーチ形フレーム１の全長に亘り形成されている抜け止め材挿通案内路１２が上記突き合わせ開口部分４０で欠落することから、この抜け止め材挿通案内路１２の欠落部を補足するために設けられたものである。尚、抜け止め材挿通案内路１２は、シート耳部保持手段２を構成するカバー部材１１の長手方向に沿ってその両側部に一対形成されるため、上記ガイドローラ３４も、両側一対の抜け止め材挿通案内路１２，１２に対応して両側一対設けられている（図１０の(b) 参照）。
【００２６】
アーチ形フレーム１の直線状フレーム部材１ａと曲線状フレーム部材１ｂは、図１１に示すように、両側一対の中間連結部材３６，３６によって連結される。即ち、直線状フレーム部材１ａと曲線状フレーム部材１ｂとの連結端部を両側一対の中間連結部材３６，３６で挟み付けて、ボルト３２により締結する。
【００２７】
上記のような構成よりなる仮設テントの施工方法について説明する。この帯状シート３を張設するにあたって、先ず、仮設テントの骨組みを施工する。即ち、図１に示すように正面視略々山形に形成されて、シート耳部保持手段２を備えたアーチ形フレーム１を、図２に示すように所要間隔おきに並行配置すると共に、隣合うアーチ形フレーム１，１同士を複数本の水平支持部材６により連結し、そして各アーチ形フレーム１の上部側にシート耳部保持手段２のカバー部材１１を取り付け、骨組みの施工を完了する。
【００２８】
上記のようにして骨組みの施工が完了したならば、図１に示すように、帯状シートが連続的に巻かれてストックされているシート巻取り機３７より帯状シート３を繰り出し、この帯状シート３の先端にシート引込み用ワイヤーロープ３５を連結し、このワイヤーロープ３５をウインチ３８に連動連結する。この場合、各アーチ形フレーム１に装備したシート耳部保持手段２のカバー部材１１の先端側にガイドローラ３９（図１参照）を設けて、ウインチ３８に連動連結されたシート引込み用ワイヤーロープ３５をそのガイドローラ３９で案内すると共に、アーチ形フレーム１の頂部Ｏでは前記したガイドローラ３４によってワイヤーロープ３５を案内する。
【００２９】
しかして、シート巻取り機３７より帯状シート３を繰り出しながら、帯状シート３の両耳部４，４の抜け止め材１０，１０を手作業によってシート耳部保持手段２の抜け止め材挿通案内路１２，１２の夫々一端側に導入させた後、ウインチ３８を巻き取り操作すれば、シート引込み用ワイヤーロープ３５によって帯状シート３が引っ張られ、それにより帯状シート３の両耳部４，４の抜け止め材１０，１０は、隣合うアーチ形フレーム１，１のカバー部材１１，１１の抜け止め材挿通案内路１２，１２に沿って移動しながら、隣合うアーチ形フレーム１，１の全長に亘って帯状シート３が張設されることになる。この際、アーチ形フレーム１の頂部Ｏ側にガイドローラ３４が設けられているから、帯状シート３の両耳部４，４の抜け止め材１０，１０はカバー部材１１，１１の抜け止め材挿通案内路１２，１２をスムーズに移動することができる。こうして両耳部４，４がシート緊張手段５により保持されただけの帯状シート３は、図６の(a) に示すように弛緩状態にある。
【００３０】
そこで、上記のように隣合うアーチ形フレーム１，１のシート耳部保持手段２により両耳部４，４を保持しただけで弛緩状態にある帯状シート３の耳部４の近傍を、シート緊張手段５により上から押え付けることによって、帯状シート３を緊張させるわけである。即ち、このシート緊張手段５によって帯状シート３を緊張させるには、図４によって既に説明したように、シート耳部保持手段２のカバー部材１１を貫通して上方に突出したボルト２１の突出部にスペーサ用ナット２３を螺合した後、このボルト２１を連結金具１８のボルト挿通孔１９に挿通してその挿通端部に締付用ナット２４を螺合し、この締付用ナット２４を締め付けて、連結金具１８を、カバー部材１１及びスペーサ用ナット２３を介してアーチ形フレーム１の上部フランジ８に固定すれば、それまで図６の(a) のような弛緩状態にあった帯状シート３は、両側にある押え棒１７，１７により上から押え付けられて、隣合うアーチ形フレーム１，１間に張設された帯状シート３の全体に亘り同図の(b) に示すように良好な緊張状態となる。
【００３１】
こうして隣合うアーチ形フレーム１，１間の帯状シート３をシート緊張手段５によって緊張させた後、このシート緊張手段５の連結金具１８と連結金具１８との中間に押え棒押え金具２５を取り付けることにより、シート緊張手段５の押え棒１７を確実固定して、帯状シート３の緊張状態を長期に亘って安定なものとすることができる。
【００３２】
上記のようにして施工された仮設テントから帯状シート３を取り外す時には、押え棒押え金具２５及びシート緊張手段５を夫々取り外すか、又は取り外すことなく帯状シート３が緩んだ状態となるように弛緩操作した後、帯状シート３の後端部を適当長さ引っ張り出してシート巻取り機３７に連結し、このシート巻取り機３７を巻取り操作することによって、帯状シート３を隣合うアーチ形フレーム１，１間から取り外すことができる。もちろん、シート巻取り機３７を使用することなく、帯状シート３を手動で引き出してもよい。
【００３３】
以上説明したように、この発明の仮設テントにおいては、隣合うアーチ形フレーム１，１のシート耳部保持手段２，２によって両耳部４，４を保持された帯状シート３の耳部４，４近傍を上から押え付けて帯状シート３を緊張させるためのシート緊張手段５をアーチ形フレーム１に設けているから、隣合うアーチ形フレーム１，１間に予め弛緩状態で張設した帯状シート３を、このシート緊張手段５によって簡単容易に緊張させることができ、従って仮設テントの施工を短時間で能率良く行うことができ、施工費の大幅な低減を図ることができる。
【００３４】
また、このシート緊張手段５は、帯状シート３の耳部４，４近傍を上から押える両側一対の押え棒１７，１７と、両押え棒１７，１７をつなぐ複数の略下向きコ字状の連結金具１８とからなるもので、構造が簡単で部品点数も少ないから、製作コストを安くできるものである。
【００３５】
【発明の効果】
請求項１に係る発明によれば、隣合うアーチ形フレームのシート耳部保持手段によって両耳部を保持された帯状シートの耳部近傍を上から押え付けて帯状シートを緊張させるためのシート緊張手段をアーチ形フレームに設けたことにより、隣合うアーチ形フレーム間に予め弛緩状態で張設した帯状シートを、従来装置のようにアーチ形フレームを移動させることなく、このシート緊張手段によって簡単容易に緊張させることができ、従って仮設テントの施工を短時間で能率良く行うことができ、施工費の大幅な低減を図ることができる。
【００３６】
また本発明によれば、シート緊張手段は、帯状シートの耳部近傍を上から押える両側一対の押え棒と、両押え棒をつなぐ複数の略下向きコ字状の連結金具とからなるもので、構造が簡単で部品点数も少ないから、製作コストを安くできる上に、取扱いが簡単で作業を容易に行なうことができる。
【００３７】
請求項２に係る発明によれば、各アーチ形フレームにはシート緊張手段の押え棒の所要部を上から押え付ける押え棒押え金具が取り付けられるようになっているから、この押え棒押え金具により、シート緊張手段の押え棒を確実固定して、帯状シートの緊張状態を長期に亘って安定なものとすることができる。
【００３８】
請求項３に係る発明によれば、押え棒押え金具は、略下向きコ字状の金具本体と、この金具本体の両端に取り付けられて、両押え棒に夫々上方より係嵌する係嵌部材とからなるもので、構造簡単で安価に製作することができると共に、取扱いが簡単で作業を容易に行なうことができる。
