Description

【０００１】
【発明の属する技術分野】
本発明は網目部を有するふとん篭本体と網目部を有する蓋体とを備え、ふとん篭本体内に石詰めして崖の法面や河岸や海岸などに施工するふとん篭およびそのふとん篭への石詰め方法に関するもので、特に、吊下げ時の耐変形強度を改善したふとん篭およびそのふとん篭への石詰め方法に関するものである。
【０００２】
【従来の技術】
従来のふとん篭１００は、図５に示すように、ふとん篭本体１１０と、蓋体２１０（図示省略）とを備えている。ふとん篭本体１１０は、底部１２０と、第１面部１３０，第２面部１４０，第３面部１５０，第４面部１６０とを備えた箱型形状のもので、それぞれが複数の縦枠線材１７０と、複数の横枠線材１８０とを矩形状に結合し、所用数の中間線材１９０を設け、これらの縦枠線材１７０と横枠線材１８０と中間線材１９０とで形成される面に線材を網目状に掛け渡した網目部とを有する。
【０００３】
上記のふとん篭１００は、ふとん篭本体１１０内に石詰めを行い、蓋体２１０で覆って、崖の法面や河岸や海岸などに施工されている。一般に、このようなふとん篭１００は、平場にしても、傾斜地にしても、現場での組立、石詰め施工が行われている。一部、築堤マットのように大型ふとん篭で、かつ、水中施工の場合には、予め石詰め製作したものを吊下げて沈める工法も採用されている（非特許文献１参照。）。
【０００４】
現場での石詰め作業の場合、特に傾斜地では施工性が悪く、詰め石の重量などに起因するふとん篭のずり落ちや変形を出来るだけ抑えるために、補強枠や仮枠などを施して、機械と人力による石詰めを行っている。（例えば、特許文献１参照。）。
【０００５】
また、ふとん篭の変形を抑えるために、図６に示すふとん篭３００のように、第２面部１４０と第４面部１６０との間に、補強用網２５０を設けることがある。また、大きいふとん篭では、図７に示すふとん篭４００のように、第２面部１４０と第４面部１６０との間に、複数の補強用網２５０ａ，２５０ｂ，２５０ｃを設けることがある（非特許文献１参照。）。
【０００６】
また、より強度を大きくするために、図８に示すふとん篭５００のように、底部１２０、第１面部１３０〜第４面部１６０および蓋体２００に、クロス状に補強線材２６０を設けることがある。

【発明が解決しようとする課題】
ところが、特許文献１に記載のふとん篭では、補強枠や仮枠などを施して、機械と人力による石詰めを行っているため、施工が困難で、施工に長時間を必要とするため、施工費が高騰するという問題点がある。
【０００９】
また、非特許文献１に記載の補強用網２３０，２３０ａ，２３０ｂ，２３０ｃを設けたふとん篭では、補強用網を設けるのが煩雑であり、コストアップの原因となる。また、補強用網では、それほどふとん篭の強度アップが期待できない。さらに、補強用網は、石爪作業前に設けておく必要があるため、石詰め作業時に補強用網が邪魔になって、石詰め作業性が悪いという問題点がある。
【００１０】
さらに、底部１２０、第１面部１３０〜第４面部１６０および蓋体２００に、クロス状に補強線材２６０を設けることは、高コストになるため、コスト的に実現が困難であるという問題点がある。
【００１１】
また、傾斜部が水中に入る部分では、水深が１ｍ程度の場合には、潜水夫による現場での石詰め、蓋掛け作業が一般的であるが、施工性が劣り、出来上がり具合の管理も容易ではない。
【００１２】
そこで、本発明は、吊下げ施工が可能な強度を有するふとん篭と、このふとん篭への石詰め方法を提供することを目的とするものである。
【００１３】
【課題を解決するための手段】
本発明のふとん篭は、上記の課題を解決するために、底部と、この底部から立上る第１面部ないし第４面部とを有し、それぞれが複数の枠線材と、任意数の中間線材と、これらの枠線材および中間線材に対して線材を掛け渡して形成した網目部とを有するふとん篭本体と、このふとん篭本体を覆う網目部を有する蓋体とを備えたふとん篭において、前記ふとん篭本体の１面部の中間線材と、この１面部に隣接する２つの面部の中間線材とに、各面部に対して斜め状に補強部材を掛け渡したことを特徴としている。
【００１４】
前記補強部材の他に、対向する２面部の中間線材間に、対向する２面部に対して直角状に第２の補強部材を掛け渡すとよい。
【００１５】
また、前記補強部材および第２の補強部材を、補強線材とするとよい。
【００１６】
また、前記１面部の中間線材と、この１面部に隣接する２つの面部の中間線材との間に掛け渡した補強線材と、前記対向する２面部の中間線材間に掛け渡した第２の補強線材とを、各中間線材の高さ方向の複数箇所に設けるとよい。
【００１７】
また、本発明のふとん篭への石詰め方法は、上記の課題を解決するために、底部と、この底部から立上る第１面部ないし第４面部とを有し、それぞれが複数の枠線材と、任意数の中間線材と、これらの枠線材および中間線材に対して線材を掛け渡して形成した網目部とを有するふとん篭本体と、このふとん篭本体を覆う網目部を有する蓋体とを備えたふとん篭における石詰め方法であって、前記ふとん篭本体内に、所定高さ寸法だけ石詰め作業を行う工程と、前記石詰め工程の後、前記ふとん篭本体の１面部の中間線材と、この１面部に隣接する２つの面部の中間線材とに、第１の補強線材を水平状で、かつ、各面部に対して斜め状に掛け渡すとともに、対向する２つの面部の中間線材間に第２の補強線材を水平状で、かつ、各面部に対して直角状に掛け渡す工程と、前記第１および第２の補強線材の掛け渡し工程後に、ふとん篭本体内に石詰め作業を行う工程とを備えたことを特徴としている。
【００１８】
すなわち、本発明のふとん篭では、ふとん篭本体の１面部の中間線材と、この１面部に隣接する２つの面部の中間線材とに、各面部に対して斜め状に補強部材を掛け渡ししたので、補強部材によってふとん篭の耐吊下げ強度が増大するので、吊下げ時のふとん篭の変形を防止することが出来る。また、傾斜地やぬかるみ地や水中など劣悪な現場ではなく、平地の屋外または屋内の作業性が良い場所で石詰め施工を行えるので、石詰め作業を効率的に行うことが出来、特に、屋内で石詰め作業を行う場合は、天候に左右されることがない。さらに、現場ではこの石詰めされたふとん篭を吊下げ施工することが出来、ふとん篭の施工性が著しく向上し、施工時間が短縮できるとともに、施工費が低減出来る。
【００１９】
また、前記補強部材の他に、対向する２面部の中間線材間に、対向する各面部に対して直角状に第２の補強部材を掛け渡すことにより、前記各面部に対して斜め状に掛け渡した補強線材との協働作用によって、石詰めしたふとん篭の吊下げ時の変形をより一層確実に防止することが出来る。
【００２０】
また、前記補強部材および第２の補強部材を、補強線材で形成すると、補強用網に比較して製作が容易であり、補強部材の低コスト化が出来るのみならず、補強用網のように最初からふとん篭本体に組込んでおく必要がなく、石詰め作業の途中で、掛け渡すことが可能になり、石詰め作業時に補強部材が邪魔になることがないので、石詰めの作業性が著しく向上する。
【００２１】
また、前記１面部の中間線材と、この１面部に隣接する２つの面部の中間線材との間に掛け渡した補強線材と、前記対向する２面部の中間線材間に掛け渡した第２の補強線材とを、各中間線材の高さ方向の複数箇所に設けると、複数段に掛け渡した補強線材の協働作用によって、より一層石詰めしたふとん篭の吊下げ時の耐変形強度を向上することが出来る。
【００２２】
この場合の補強線材の段数は、ふとん篭の高さ寸法に応じて適宜設定すれば良い。通常、最も多く用いられている高さ寸法が４００ｍｍ〜６００ｍｍ程度のふとん篭では、２段に掛け渡す程度で十分な強度が得られる。
【００２３】
また、本発明のふとん篭への石詰め方法によると、ふとん篭本体内に、所定高さ寸法だけ石詰め作業を行った後に、第１および第２の補強線材を掛け渡し、さらにふとん篭本体内に石詰め作業を行うので、最初から第１および第２の補強線材を、中間線材の所定位置に掛け渡しておく場合に比較して、第１および第２の補強線材が邪魔にならず、石詰め作業を効率良く行うことが出来る。また、ふとん篭本体内全体に石詰めを行った後に、第１および第２の補強線材を掛け渡す場合に比較して、第１および第２の補強線材を、容易、かつ、確実に各中間線材の所定の高さ位置に直線状に掛け渡すことが出来、補強線材による補強効果を最大限に発揮することが出来る。
【００２４】
【発明の実施の形態】
以下、本発明のふとん篭の実施形態を、図面に基づいて説明する。
【００２５】
本発明のふとん篭１０は、図１ないし図４に示すように、矩形箱状のふとん篭本体２０と、このふとん篭本体２０を覆う蓋体６０と、補強部材の一例として、８本の短い第１の補強線材７１と、６本の長い第２の補強線材７２とを備えている。
【００２６】
ふとん篭本体２０は、図３の展開図から明らかなように、矩形状の底部２１と、この底部２１から立上る矩形状の第１面部２２、第２面部２３、第３面部２４、第４面部２５を有する。底部２１は、短辺側の枠線材２６，２８と、長辺側の枠線材２７，２９と、短辺側の枠線材２６，２８間に掛け渡した中間線材３０と、長辺側の枠線材２７，２９間に掛け渡した補強用の３本の中間線材３１，３２，３３と、これらの枠線材２６〜２９および中間線材３０〜３３に線材を掛け渡して形成した網目部３４とを有する。
【００２７】
前記第１面部２２は、底部２１における短辺側の枠線材２６の両端から立上る２本の短い縦枠線材３５，３６と、これら２本の縦枠線材３５，３６の先端部を結ぶ１本の長い横枠線材３７と、この長い横枠線材３７と底部２１の短辺側の枠線材２６との間に掛け渡した１本の中間線材３８と、前記底部２１の枠線材２６と縦枠線材３５，３６と横枠線材３７と中間線材３８によって形成される面に線材を掛け渡して形成された網目部３９とを有する。
【００２８】
前記第２面部２３は、底部２１における長辺側の枠線材２７の両端から立上る２本の短い縦枠線材４０，４１と、これら２本の縦枠線材４０，４１の先端部を結ぶ１本の長い横枠線材４２と、この長い横枠線材４２と底部２１の長辺側の枠線材２７との間に掛け渡された３本の中間線材４３，４４，４５と、前記底部２１の枠線材２７と縦枠線材４０，４１と横枠線材４２と中間線材４３〜４５とによって形成される面に線材を掛け渡して形成された網目部４６とを有する。
【００２９】
前記第３面部２４は、底部２１における短辺側の枠線材２８の両端から立上る２本の短い縦枠線材４７，４８と、これら２本の縦枠線材４７，４８の先端部を結ぶ１本の長い横枠線材４９と、この長い横枠線材４９と底部２１の枠線材２８との間に掛け渡した１本の中間線材５０と、前記底部２１の枠線材２８と縦枠線材４７，４８と横枠線材４９と中間線材５０とによって形成される面に線材を掛け渡して形成された網目部５１とを有する。
【００３０】
前記第４面部２５は、底部２１における長辺側の枠線材２９の両端から立上る２本の短い縦枠線材５２，５３と、これら２本の縦枠線材５２，５３の先端部を結ぶ１本の長い横枠線材５４と、この長い横枠線材５４と底部２１の枠線材２９との間に掛け渡された３本の中間線材５５，５６，５７と、前記底部２１の枠線材２９と縦枠線材５２，５３と横枠線材５４と中間線材５５〜５７とによって形成される面に線材を掛け渡して形成された網目部５８とを有する。
【００３１】
そして、前記第１面部２２〜第４面部２５を、底部２１に対してそれぞれ９０°折り曲げて、第１面部２２の縦枠線材３５と、第２面部２３の縦枠線材４０とを、結合線材５９を巻き付けて結合する。同様に、第２面部２３の縦枠線材４１と第３面部２４の縦枠線材４７、第３面部２４の縦枠線材４８と第４面部２５の縦枠線材５２、第４面部２５の縦枠線材５３と第１面部２２の縦枠線材３６とを結合線材５９を巻き付けて結合することによって、ふとん篭本体２０が製作されている。
【００３２】
なお、蓋体６０は、図４に示すように、短辺側の一対の枠線材６１，６３と、長辺側の一対の枠線材６２，６４と、前記短辺側の枠線材６１，６３の中央部に掛け渡された中間線材６５と、前記長辺側の一対の枠線材６３，６４間に掛け渡された３本の中間線材６６，６７，６８と、これらの枠線材６１〜６４と中間線材６５〜６８で形成される面に線材を掛け渡して形成された網目部６９とを有する。
【００３３】
なお、この蓋体６０は、ふとん篭本体２０に石詰め作業を行った後で、ふとん篭本体２０に結合する方が石詰め作業時の作業性が良いため、出荷時には結合されていないか、簡単に取り外せる状態に仮結合されている。
【００３４】
前記第１の短い補強線材７１は、第１面部２２の中間線材３８と第２面部２３の中間線材４３間、第１面部２２の中間線材３８と第４面部２５の中間線材５５間、第３面部２４の中間線材５０と第２面部２３の中間線材４５間、第３面部２４の中間線材５０と第４面部２５の中間線材５７間に、水平状で、かつ、第１面部２２，第２面部２３，第３面部２４，第４面部２５に対して、斜め状に掛け渡されるものである。
【００３５】
前記第２の長い補強線材７２は、対向する第２面部２３の中間線材４３と第４面部２５の中間線材５５間、第２面部２３の中間線材４４と第４面部２５の中間線材５６間、第２面部２３の中間線材４５と第４面部２５の中間線材５７間に、水平状で、かつ、第２面部２３および第４面部２５に対して直角状に掛け渡されるものである。
【００３６】
前記第１の補強線材７１および第２の補強線材７２は、ふとん篭本体２０に石詰め作業を行う途中で掛け渡す方が、石詰め作業の作業性が良いため、出荷時には掛け渡されていないか、あるいは簡単に取り外せる状態で仮に掛け渡されている。
【００３７】
次に、本発明に係るふとん篭１０への石詰め作業およびその途中での第１，第２の補強線材７１，７２の掛け渡し作業について説明する。
【００３８】
まず、上記のようにして組み立てられたふとん篭本体２０を、開口部を上にして平地に配置する。そして、ふとん篭本体２０内に石詰め作業を行っていく。詰められた石の高さ寸法が、ふとん篭本体２０の高さ寸法の約２０〜３０％になった段階で、一旦、石詰め作業を中止して、第１の補強線材７１および第２の補強線材７２の掛け渡し作業を行う。
【００３９】
前述のように、２本の第１の補強線材７１を、第１面部２２の中間線材３８と、この第１面部２２に隣接する第２面部２３の中間線材４３および第４面部２５の中間線材５５とに、水平状で、かつ、各面部２２，２３，２５に対して斜め状に掛け渡す。また、２本の第１の補強線材７１を、第３面部２４の中間線材５０と、この第３面部２４に隣接する第２面部２３の中間線材４５および第４面部２５の中間線材５７とに、水平状で、かつ、各面部２４，２３，２５に対して斜め状に掛け渡す。
【００４０】
また、３本の第２の補強線材７２を、それぞれ対向する第２面部２３および第４面部２５の中間線材４３と中間線材５５、中間線材４４と中間線材５６、中間線材４５と中間線材５７とに、水平状で、かつ、各面部２３，２５に対して直角状に掛け渡す。
【００４１】
この後、再び、石詰め作業を行う。そして、詰められた石の高さ寸法が、ふとん篭本体２０の高さ寸法の約６０〜７０％になったら、石詰め作業を中止して、再度、４本の第１補強線材７１および３本の第２補強線材７２の掛け渡し作業を行う。この第１補強線材７１および第２補強線材７２を掛け渡す中間線材は、上述の場合と同様で、その掛け渡し高さ位置のみが相違するだけであるため、その詳細な説明は省略する。
【００４２】
第１の補強線材７１および第２の補強線材７２の掛け渡し作業が終了すると、また、石詰め作業を再開して、ふとん篭本体２０内全てに石詰めを行う。このようにして、ふとん篭本体２０に石詰めを完了すると、ふとん篭本体２０に蓋体６０を結合する。
【００４３】
ふとん篭本体２０への蓋体６０の結合は、石詰めを行ったふとん篭本体２０の上に蓋体６０を載せて、ふとん篭本体２０の第１面部２２の横枠線材３７と蓋体６０の枠線材６１、ふとん篭本体２０の第２面部２３の横枠線材４２と蓋体６０の枠線材６２、ふとん篭本体２０の第３面部２４の横枠線材４９と蓋体６０の枠線材６３、ふとん篭本体２０の第４面部２５の横枠線材５４と蓋体６０の枠線材６４とを、それぞれ結合線材５９を巻き付けることによって結合する（図示省略）。
【００４４】
以下、本発明のふとん篭の実施例について説明する。
【００４５】
底部２１の枠線材２６〜２９および中間線材３０〜３３、第１面部２２〜第４面部２５の縦枠線材３５，３６、４０，４１、４７，４８、５２，５３、横枠線材３７，４２，４９，５４および中間線材３８，４３〜４５，５０，５５〜５７、第１の補強線材７１および第２の補強線材７２に、φ６．０ｍｍの亜鉛めっき鋼線を使用し、底部２１、第１面部２２〜第４面部２５の網目部３４，３９，４６，５１，５８の線材および結合線材５９にφ４．０ｍｍの亜鉛めっき鋼線を使用して、長さ寸法Ｌ＝２，０００ｍｍ、幅寸法Ｗ＝１，２００ｍｍ、高さ寸法Ｈ＝５００ｍｍのふとん篭本体２０を製作した。
【００４６】
また、蓋体６０の枠線材６１〜６４および中間線材６５〜６８に、φ６．０ｍｍの亜鉛めっき鋼線を使用し、網目部６８の線材にφ４．０ｍｍの亜鉛めっき鋼線を使用して、長さ寸法Ｌ＝２，０００ｍｍ、幅寸法Ｗ＝１，２００ｍｍの蓋体６０を製作した。
【００４７】
前記ふとん篭本体２０への詰め石粒径＝１５０〜２００ｍｍ、第１の補強線材７１および第２の補強線材７２における下段の掛け渡し高さ寸法Ｈ１＝１０〜１５ｍｍ、第１の補強線材７１および第２の補強線材７２における上段の掛け渡し高さ寸法Ｈ２＝３０〜３５ｍｍとした。この石詰めしたふとん篭本体２０に、蓋体６０をφ４．０ｍｍの亜鉛めっき鋼線からなる結合線材５９を使用して、ふとん篭本体２０に結合した。
【００４８】
この石詰めしたふとん篭１０を、吊下げ条件＝３割勾配、６点吊りで、３０〜４０秒間吊下げて、ふとん篭１０の荷崩れの有無および変形量を測定したところ、次のような結果が得られた。

この程度の変形量であれば、実用上、全く問題が無いことが確認された。
【００４９】
なお、上記の説明は、特定の実施形態および実施例について説明したが、本発明はこの実施形態や実施例に限定されるものではなく、その精神を逸脱しない範囲において、各種の変形が可能である。
【００５０】
例えば、上記の実施形態では、第１および第２の補強部材として、補強線材７１および７２を用いる場合について説明したが、いずれか一方または両方に補強用網を用いてもよい。
【００５１】
また、ふとん篭１０の長さ寸法Ｌ，幅寸法Ｗおよび高さ寸法Ｈは、施工場所、石詰め作業性、運搬性、施工性などを考慮して任意に設定すればよい。その大きさに応じて、枠線材、中間線材、網目部の線材などの太さ寸法、中間線材の本数などを適宜設定すればよい。場合によっては、その形状を矩形状のみならず、正方形にしてもよい。
【００５２】
また、網目部の網目の大きさは、詰め石の粒径に応じて適宜設定すればよい。なお、現地で石詰めする場合に比較して、若干、網目部の網目を小さ目に設定する方が、ふとん篭を吊下げた場合に、詰めた石の重みで網目が開いて詰め石が漏れ出ることが無くなる。
【００５３】
また、上記実施形態では、第１の補強線材７１および第２の補強線材７２を併用する場合について説明したが、ふとん篭１０が小さい場合は、第１の補強線材７１のみを使用するようにしてもよい。また、第１の補強線材７１および第２の補強線材７２を２段に使用する場合について説明したが、ふとん篭１０の高さ寸法が小さい場合は１段のみでもよいし、ふとん篭１０の高さ寸法が大きい場合は３段以上にしてもよい。
【００５４】
【発明の効果】
本発明のふとん篭は、底部と、この底部から立上る第１面部ないし第４面部とを有し、それぞれが複数の枠線材と、任意数の中間線材と、これらの枠線材および中間線材に対して線材を掛け渡して形成した網目部とを有するふとん篭本体と、このふとん篭本体を覆う網目部を有する蓋体とを備えたふとん篭において、前記ふとん篭本体の１面部の中間線材と、この１面部に隣接する２つの面部の中間線材とに、各面部に対して斜め状に補強部材を掛け渡したので、ふとん篭の強度が増大して、石詰めしたふとん篭の吊下げ施工法を採用することが出来、現場での施工性が向上する。また、天候や波の状況に左右されず、組立、石詰め作業が出来るので、工期が短縮される。さらに、精度の高い品質管理が期待出来る。
【００５５】
また、前記補強部材の他に、対向する２面部の中間線材間に、対向する２面部に対して直角状に第２の補強部材を掛け渡すことにより、前記１面部の中間線材と、この面部に隣接する２面部の中間線材とに、各面部に対して斜め状に掛け渡した補強部材との協働作用によって、ふとん篭の吊下げ時の変形をより一層確実に防止することが出来る。
【００５６】
また、補強部材および第２の補強部材を補強線材で形成することにより、補強網を用いる場合に比較して、補強部材を低コスト化出来るのみならず、石詰め作業の途中で掛け渡し作業を行うことが出来るので、補強部材が邪魔にならず、石詰めの作業性が著しく向上する。
【００５７】
また、前記１面部の中間線材と、この１面部に隣接する２つの面部の中間線材との間に掛け渡した補強線材と、前記対向する２面部の中間線材間に掛け渡した第２の補強線材とを、各中間線材の高さ方向の複数箇所に設け渡すことによって、石詰めしたふとん篭の吊下げ時の変形をより一層確実に防止することが出来る。
【００５８】
また、本発明のふとん篭における石詰め方法は、ふとん篭本体内に、所定高さ寸法だけ石詰め作業を行った後、ふとん篭本体の１面部の中間線材と、この１面部に隣接する２つの面部の中間線材とに、第１の補強線材を水平状で、かつ、各面部に対して斜め状に掛け渡すとともに、対向する２つの面部の中間線材間に第２の補強線材を水平状で、かつ、対向する２面部に対して直角状に掛け渡し、さらに、ふとん篭本体内に石詰め作業を行うようにしたので、石詰め作業時に、補強線材が邪魔になることがなく、石詰め作業時の作業性が著しく向上する。

[0003]
The above-mentioned futon basket 100 is stuffed into the futon basket main body 110, covered with a lid 210, and constructed on a cliff slope, a river bank, a coast, or the like. In general, such a futon basket 100 is subjected to on-site assembling and stuffing work on a flat ground or on a slope. In some cases, in the case of underwater construction, a method of suspending and sinking a large futon basket, such as an embankment mat, which is manufactured by stuffing in advance (see Non-Patent Document 1).
[0004]
In the case of on-site stone stuffing work, the workability is poor especially on sloping land, and in order to minimize as much as possible the slippage and deformation of the futon basket caused by the weight of the stuffing stone, a reinforcing frame or temporary frame is applied, And stuffing with human power. (For example, refer to Patent Document 1).
[0005]

[Problems to be solved by the invention]
However, in the case of the futon basket described in Patent Literature 1, since a stone is stuffed by a machine and human power by providing a reinforcing frame or a temporary frame, the construction is difficult, and a long time is required for the construction. There is a problem that costs rise.
[0009]
Also, in the case of the futon provided with the reinforcing nets 230, 230a, 230b, 230c described in Non-Patent Document 1, providing the reinforcing nets is complicated and causes an increase in cost. In addition, the reinforcement net cannot be expected to increase the strength of the futon basket so much. Furthermore, since the reinforcing net needs to be provided before the stone claw work, there is a problem that the reinforcing net becomes a hindrance at the time of stone stuffing work, and the stone stuffing workability is poor.
[0010]
Further, providing the reinforcing wire 260 in a cross shape on the bottom portion 120, the first surface portion 130 to the fourth surface portion 160, and the cover 200 has a problem that it is difficult to realize the cost because it is expensive. .
[0011]
In the part where the inclined part enters the water, when the water depth is about 1m, divers are generally stuffed with stones and covered with a lid by the diver, but the workability is poor and the finished condition is easy to manage. is not.
[0012]
Therefore, an object of the present invention is to provide a futon basket having a strength capable of suspending construction and a method of stuffing stones into this futon basket.
[0013]
[Means for Solving the Problems]
The futon basket of the present invention has a bottom portion, a first surface portion to a fourth surface portion rising from the bottom portion, and a plurality of frame wires and an arbitrary number of intermediate wires, respectively, in order to solve the above problem. A futon basket comprising: a futon basket main body having a mesh portion formed by laying a wire over the frame wire and the intermediate wire; and a lid having a mesh portion covering the futon basket main body. It is characterized in that a reinforcing member is extended obliquely with respect to each surface portion between an intermediate wire on one surface of the basket body and an intermediate wire on two surfaces adjacent to the one surface.
[0014]
In addition to the reinforcing member, a second reinforcing member may be stretched between the opposing two surface portions at right angles to the opposing two surface portions.
[0015]
Further, the reinforcing member and the second reinforcing member may be a reinforcing wire.
[0016]
Further, a reinforcing wire spanned between the intermediate wire of the one surface and the intermediate wire of two surfaces adjacent to the one surface, and a second reinforcement spanned between the intermediate wires of the opposed two surfaces. The wire may be provided at a plurality of positions in the height direction of each intermediate wire.
[0017]
In addition, in order to solve the above-described problems, the method for stuffing stones into a futon basket according to the present invention has a bottom portion, a first surface portion to a fourth surface portion rising from the bottom portion, each of which includes a plurality of frame wires. A futon basket body having an arbitrary number of intermediate wires, a mesh portion formed by bridging the frame wire and the intermediate wire, and a lid having a mesh portion covering the futon basket body. A method for stuffing stones in a futon basket, wherein the step of stuffing stones by a predetermined height in the futon basket main body, and after the stone stuffing step, an intermediate wire rod on one surface of the futon basket main body, The first reinforcing wire is horizontally laid on the intermediate wire of the two surfaces adjacent to the one surface and obliquely to each of the surfaces, and the first reinforcing wire is interposed between the intermediate wires of the two opposing surfaces. 2 Reinforcing wire is horizontal and for each surface A step to bridge the angular, after passing steps over the first and second reinforcing wire is characterized by comprising a step of performing a stone filling work futon basket body.
[0018]
That is, in the futon basket of the present invention, the reinforcing member is obliquely laid over the intermediate wire on one surface of the futon basket main body and the intermediate wire on two surfaces adjacent to the one surface. In addition, since the reinforcing member increases the hanging strength of the futon basket, deformation of the futon basket during hanging can be prevented. In addition, stone stuffing work can be performed in a place with good workability outdoors or indoors, not on a bad site such as sloping land, muddy ground or underwater, so stone stuffing work can be performed efficiently, especially indoors When performing stuffing work, it is not affected by the weather. Further, at the site, the stone-stuffed futon basket can be suspended and constructed, and the workability of the futon basket can be remarkably improved, the construction time can be shortened, and the construction cost can be reduced.
[0019]
In addition, in addition to the reinforcing member, a second reinforcing member is provided between the intermediate wire rods of the two opposing surfaces at right angles to the opposing surfaces, so that the second reinforcing member is slanted to the surfaces. By the cooperative action with the passed reinforcing wire rod, the deformation of the stuffed futon basket at the time of suspension can be more reliably prevented.
[0020]
In addition, when the reinforcing member and the second reinforcing member are formed of a reinforcing wire, it is easier to manufacture than a reinforcing net, and not only can the cost of the reinforcing member be reduced, but also the reinforcing net can be It is not necessary to incorporate it into the body of the futon basket from the beginning, and it is possible to hang it in the middle of stone filling work, and the reinforcing member does not become an obstacle during stone filling work, so workability of stone filling is improved. Significantly improved.
[0021]
Further, a reinforcing wire spanned between the intermediate wire of the one surface and the intermediate wire of two surfaces adjacent to the one surface, and a second reinforcement spanned between the intermediate wires of the opposed two surfaces. When the wire is provided at a plurality of locations in the height direction of each intermediate wire, the cooperative action of the reinforcing wire spanned over a plurality of stages improves the deformation resistance during hanging of the futon basket further packed with stones. I can do it.
[0022]
In this case, the number of steps of the reinforcing wire may be appropriately set according to the height of the futon basket. Normally, in the case of the most widely used futon basket having a height dimension of about 400 mm to 600 mm, sufficient strength can be obtained by bridging over two stages.
[0023]
Further, according to the method for packing stones in the futon basket according to the present invention, after the stuffing operation is performed within the futon basket body by a predetermined height, the first and second reinforcing wires are laid over the futon basket body. Since the stuffing work is performed inside the first and second reinforcing wires, the first and second reinforcing wires are not in the way as compared with the case where the first and second reinforcing wires are laid over the predetermined position of the intermediate wire from the beginning. In addition, the work of stuffing stones can be performed efficiently. Further, the first and second reinforcing wires are easily and reliably inserted into the respective intermediate portions in comparison with the case where the first and second reinforcing wires are bridged after the entire inside of the futon basket body is packed with stones. The wire can be linearly bridged at a predetermined height of the wire, and the reinforcing effect of the reinforcing wire can be maximized.

Further, the size of the mesh of the mesh portion may be appropriately set according to the particle size of the packing stone. In addition, compared to the case where stones are packed locally, it is better to set the mesh of the mesh part to a smaller size, and when the futon basket is hung, the meshes will open due to the weight of the packed stones and the packing stones will leak. You will not get out.
[0053]
In the above-described embodiment, the case where the first reinforcing wire 71 and the second reinforcing wire 72 are used together has been described. However, when the bedding basket 10 is small, only the first reinforcing wire 71 is used. Is also good. Also, the case where the first reinforcing wire 71 and the second reinforcing wire 72 are used in two steps has been described. However, when the height of the futon basket 10 is small, only one step may be used. If the size is large, three or more stages may be used.
[0054]
【The invention's effect】
The futon basket of the present invention has a bottom portion, a first surface portion to a fourth surface portion rising from the bottom portion, each of which includes a plurality of frame wires, an arbitrary number of intermediate wires, and these frame wires and intermediate wires. A futon basket body having a mesh portion formed by laying a wire over the futon basket body, and a cover having a mesh portion covering the futon basket body, wherein an intermediate wire rod on one surface of the futon basket body; Since the reinforcing member is skewed to the intermediate wire between the two surfaces adjacent to the one surface, the strength of the futon basket is increased, and the hanging of the futon basket packed with stones is performed. The method can be adopted, and the workability at the site is improved. Also, assembling and stuffing work can be performed without being affected by the weather or wave conditions, thereby shortening the construction period. Furthermore, high quality control can be expected.
[0055]
Further, in addition to the reinforcing member, a second reinforcing member is laid at right angles to the opposing two surface portions between the opposing two surface portions of the intermediate wire material, so that the one surface portion of the intermediate wire member and this surface portion By cooperating with the intermediate wire rods on the two surfaces adjacent to the surface member and the reinforcing member that extends obliquely with respect to each surface, deformation during hanging of the futon basket can be more reliably prevented.
[0056]
Further, by forming the reinforcing member and the second reinforcing member with a reinforcing wire, not only can the cost of the reinforcing member be reduced as compared with the case where a reinforcing net is used, but also the bridging work can be performed in the middle of the stuffing work. Since it can be performed, the reinforcing member does not become an obstacle, and the workability of stuffing stones is remarkably improved.
[0057]
Further, a reinforcing wire spanned between the intermediate wire of the one surface and the intermediate wire of two surfaces adjacent to the one surface, and a second reinforcement spanned between the intermediate wires of the opposed two surfaces. By providing the wire at a plurality of locations in the height direction of each intermediate wire, deformation during hanging of the stuffed futon basket can be more reliably prevented.
[0058]
Further, the method for stuffing stones in the futon basket according to the present invention is such that after the stuffing work is performed in the futon basket main body by a predetermined height, an intermediate wire rod on one side of the futon basket main body, and 2 The first reinforcing wire is horizontally extended to the intermediate wire of the two surface portions, and the first reinforcing wire is obliquely extended to each of the surface portions, and the second reinforcing wire is horizontally interposed between the opposed intermediate wire materials of the two surface portions. In addition, since the work is wrapped at right angles to the two opposing surfaces and the stuffing work is performed inside the futon basket body, the reinforcing wire is not in the way during the stuffing work. Workability at the time of filling work is remarkably improved.
