【発明の属する技術分野】
本発明は、複数の柱部材と、隣接する前記柱部材同士を連結する複数の梁部材と、中空の矩形形状に形成されたパネルとによって、平面視で略四角形状の周壁部が形成されるとともに、前記パネルが前記柱部材及び前記梁部材にて区画形成される矩形状の枠部分の内周部に組み付けられるように構成され、前記周壁部にて囲まれる領域に乾燥又は貯蔵のために穀物を貯留する穀物貯留空間が形成されている穀物貯留設備に関する。
【０００２】
【従来の技術】
上記構成の穀物貯留設備として、従来では、例えば、特開平１１−３１３５３４号公報に示されるように、前記複数の柱部材と複数の梁部材とがネジ式締結手段にて組み付けられるとともに、前記柱部材及び前記梁部材にて区画形成される矩形状の枠部分の内周部に額縁状の枠体が設けられ、前記パネルの周囲をパネル厚さ方向に沿って前記枠体にネジ式締結手段にて組み付けられるように構成されたものがあった。このようにして構成される穀物貯留空間は、生産者により搬入される多量の穀物をできるだけ少ないスペースで貯留するために背高に構成されることになり、しかも、例えば複数の生産者の穀物を互いに区分けして各別に管理する状態で貯留することができるように、隣接する穀物貯留空間同士が側壁部を共用する状態で複数の穀物貯留空間が形成される構成が一般的である。
【０００３】
そして、このような大型の設備である穀物貯留設備を設置個所にて組立てる場合には、複数の柱部材と複数の梁部材とをネジ式締結手段にて順次組み付けるとともに、柱部材及び梁部材にて区画形成される矩形状の枠部分の内周部に前記パネルを順次組み付けていくのであるが、ネジ式締結手段による締結作業を行う場合、地面に近い低い位置で行うときは作業を行い易いのであるが、高い個所において締結作業を行うときは地面からそのまま作業を行うことができないので、例えば、上記したような各部材とは別に用意された組み立て式の足場を利用して上記したような締結作業を行うようになっていた。
つまり、穀物貯留設備の外周側に位置するように外側の足場が組まれるとともに、穀物貯留設備における内方側に位置する穀物貯留空間に対しては、内側の空間に位置するように内側の足場が組まれて、外側の足場を利用して外周部側に位置する柱部材、梁部材、パネル等をネジ式締結手段にて順次組み付けるとともに、内方側に位置する穀物貯留空間に対して内側の足場を利用して柱部材、梁部材、パネル等をネジ式締結手段にて順次組み付けるようにしていた。
【０００４】
【発明が解決しようとする課題】
上記したような組み立て式の足場を利用して締結作業を行う場合において、外側の足場と、内側の足場とを夫々、用意しなければならないが、前記内側の足場を用意する場合において、平面視で略四角形状に区画された周壁部の内部に足場を形成したり、組み付け作業が終了した後に前記足場を撤去するといった作業は行い難く煩わしい作業となっていた。特に、穀物貯留空間の個数が多くなると、このような足場の準備作業や撤去作業等の作業の手間が大となり、設備全体としての組み立て作業の能率を低下させる不利な面があった。
【０００５】
本発明はかかる点に着目してなされたものであり、その目的は、組み立て作業を極力、能率よく行うことが可能となる穀物貯留設備を提供する点にある。
【０００６】
【課題を解決するための手段】
請求項１に記載の特徴構成によれば、複数の柱部材と、隣接する前記柱部材同士を連結する複数の梁部材と、中空の矩形形状に形成されたパネルとによって、平面視で略四角形状の周壁部が形成されるとともに、前記パネルが前記柱部材及び前記梁部材にて区画形成される矩形状の枠部分の内周部に組み付けられるように構成され、前記周壁部にて囲まれる領域に乾燥又は貯蔵のために穀物を貯留する穀物貯留空間が形成されている穀物貯留設備において、前記周壁部にて囲まれる領域の内側に、前記周壁部に位置固定状態で組み付け作業用のハシゴが取付けられている。
【０００７】
柱部材、梁部材、パネルの夫々を組み付ける場合には、例えば、設備の外周側に外側の足場を組んで、この外側の足場を利用して、柱部材と梁部材との組み付け作業や、パネルの組み付け作業等を下側から上方側に向けて順次行っていくことになるが、平面視で略四角形状の周壁部にて囲まれる領域の内側に位置固定状態で組み付け作業用のハシゴが取付けられているから、上記したように順次、組み付け作業が実行されることによって、周壁部の内側に設けられた前記ハシゴが形成されることになる。
従って、高い個所において前記柱部材及び前記梁部材にて区画形成される矩形状の枠部分にパネルを組み付ける場合であっても、周壁部の内部空間に専用の足場を設けることなく、作業者は、周壁部の内側に設けられた前記ハシゴを利用して高い個所にまで移動してパネルの締結作業を行うことができるものとなる。
【０００８】
従って、組み付け作業用の足場としては、設備の外周側に位置する外側の足場だけを組むだけでよく、足場の準備や撤去等は煩わしいものとなる内側の足場を設ける必要がなく、組み立て作業を極力、能率よく行うことが可能となる穀物貯留設備を提供できるに至った。
また、上下方向に沿う軸芯周りで回転しながら前記穀物貯留空間に貯留される穀物を攪拌処理する攪拌スクリューが、平面視にて略直交する２方向夫々に移動操作自在に設けられ、前記周壁部にて囲まれる領域における平面視にて四隅夫々の角部に対応する位置に、前記組付け作業用のハシゴが構成され、前記組付け作業用のハシゴの存在空間と前記穀物貯留空間とを上下方向ほぼ全域にわたって遮断する仕切り板が設けられている。
上下方向に沿う軸芯周りで回転する攪拌スクリューが平面視にて略直交する２方向夫々に移動操作されることによって前記穀物貯留空間に貯留される穀物に対する攪拌処理を行うようになっているが、穀物貯留空間に貯留される穀物に対して極力、未攪拌領域が生じないように攪拌スクリューを移動操作させるようにしている。しかし、上記したように穀物貯留空間を形成する周壁部は平面視で略四角形状に設けられるので、周壁部にて囲まれる領域の平面視における四隅夫々の角部に対応する位置においては、例えば、図２６に示すように、その構成上、前記攪拌スクリューによる攪拌処理が行えない未攪拌領域が生じることになる。そこで、このような未攪拌領域となる四隅夫々の角部に、前記組付け作業用のハシゴが構成されるので、前記攪拌スクリューによる攪拌処理の邪魔にならない状態で合理的な位置に組み付け作業用のハシゴが設けられることになる。
しかも、前記組付け作業用のハシゴの存在空間と前記穀物貯留空間とを上下方向ほぼ全域にわたって遮断する仕切り板が設けられるので、穀物貯留空間の内部に前記組付け作業用のハシゴが存在しないので穀物が搬出された後に前記組付け作業用のハシゴの上面部に穀物が載置残留するといった不利を回避できるとともに、攪拌スクリューによる未攪拌域となる角部を仕切り板にて遮断することで攪拌されない穀物をできるだけ少ないものにできる。
【０００９】
請求項２に記載の特徴構成によれば、請求項１において、前記パネルが、前記矩形状の枠部分の四隅に対応する角部夫々を欠除する形状として、その欠除した部分にパネルの外周部から外方側に向けて突出する状態で取付け用板材を設けて構成され、前記柱部材及び前記梁部材夫々の前記矩形状の枠部分の四隅に対応する箇所に、前記矩形状の枠部分の内方側に向けて突出する状態で連結用板材が設けられ、前記取付け用板材と前記連結用板材とを、夫々の厚み方向に重ねる状態で前記厚み方向に沿ってネジ式締結手段にて締結することにより、前記柱部材及び前記梁部材夫々に対して前記パネルを連結固定するように構成されている。
【００１０】
中空の矩形形状に形成されるパネルが、前記矩形状の枠部分の四隅に対応する角部夫々を欠除する形状として、その欠除した部分にパネルの外周部から外方側に向けて突出する状態で取付け用板材を設け、且つ、柱部材や梁部材に枠部分の内方側に向けて突出する状態で連結用板材を設けて、取付け用板材と連結用板材とを厚み方向に沿ってネジで締め付けることによってパネルと柱部材や梁部材との間の連結が行われる。
例えば、軽量化するためにパネル全体を薄肉の板材で中空の矩形形状に構成するようにした場合であっても、取付け用板材は、パネル用板材のように薄肉構造にする必要がなく、充分な強度を有する厚みを備えた板材で構成することが可能となる。
【００１１】
従って、パネルのネジ締結個所が四隅の角部に設けられる構成とすることで、パネルのネジ締結個所がパネルの外周部全周にわたって設けられるような構成に比べて、ネジ締結作業を極力容易に行うことができるものでありながら、しかも、中空の矩形形状のパネルを構成する板材を薄肉構造にして軽量化する構成を採用するようにしても、柱部材や梁部材に対するネジ締結部分において充分な支持強度を有するものに構成できて耐久性に優れたものとなり、請求項１を実施するのに好適な手段が得られる。
【００１２】
請求項３に記載の特徴構成によれば、請求項１又は２において、上下方向に設定間隔をあけて並べて前記柱部材の上下方向のほぼ全長にわたって、前記柱部材に固定される状態で複数の足置き部材が設けられて、これらの複数の足置き部材により前記組付け作業用のハシゴが構成される。
【００１３】
前記組付け作業用のハシゴを構成する複数の足置き部材が柱部材に固定される状態で設けられることになる。
【００１５】
【発明の実施の形態】
以下、本発明に係る穀物貯留設備の実施の形態を、図面に基づいて説明する。
図１に示すように、穀物処理設備は、納入者が穀物の荷受け処理を行う荷受け部Ａ、穀物を貯留するとともに乾燥処理する貯留ビンＤ、穀物の籾摺調整を行う籾摺調整部Ｅ及び出荷処理を行う出荷部Ｆ等を備えて構成されている。ここで、貯留ビンＤの貯留空間が穀物を乾燥処理する乾燥用の貯留空間Ｄｉに対応し、貯留ビンＤによって、乾燥又は貯蔵のために穀物を貯留する貯留空間Ｄｉを備えた穀物貯留設備が構成される。
【００１６】
荷受け部Ａは、穀物を受け入れる荷受けホッパー２１、荷受けホッパー２１からの穀物を横送りする荷受けコンベア２２、穀物を揚送する第１揚送コンベア２３、穀物を一旦貯留する流量調整タンク２４、穀物から藁屑等の異物を除去するための粗選機２５、精選処理時には粗選機２５から排出される穀物を精選別する精選機２６、荷受け処理時には粗選機２５から排出される穀物を計量し、精選処理時には精選機２６から排出される穀物を計量する荷受け用計量機２７、粗選機２５から排出される枝梗付き籾等から枝梗等を除去する脱芒機２８、精選機２６から排出される脱ぷ米を貯留する脱ぷ米タンク２９等を備えている。
又、籾摺調整部Ｅには、調整タンク６１、籾摺調整装置６２、石抜機６３等が備えられ、出荷部Ｆには、計量タンク６４、出庫用計量機６５、自動給袋機６６等が備えられている。
【００１７】
荷受け時において、荷受け用計量機２７から排出される計量後の穀物は、第２揚送コンベア６７によって揚送され、穀粒供給手段の一例である供給用コンベア６８によって貯留ビンＤのいずれかに貯留されることになる。貯留ビンＤに貯留されて乾燥処理された穀物は、各下端部の排出部６９から後述のように送風によって排出されて横送りコンベア７０及び各搬送コンベアにより攪拌装置が設けられていない、いずれかの貯留ビンＤに供給されて貯留され、精選処理時には、荷受け部Ａの第１揚送コンベア２３に搬送されて精選処理されたのち戻され、又、出荷処理時には、籾摺調整部Ｅに供給され更に出荷部Ｆを通して出荷されるようになっている。
【００１８】
次に各貯留ビンＤの構成について説明する。
図２、図３に示すように、前後方向に７個の貯留ビンＤが並列配置されて１組の乾燥貯留部が構成され、その乾燥貯留部が横方向に４組並列配置される状態で設けられている。そして、図１５、図１６に示すように、各組の貯留ビンＤの夫々に対して多孔状で通気可能な床部３１の下方側から導入して貯留ビンＤの上部から排出するように通風させる送風機３２を設け、貯留ビンＤ夫々の上部に対して排気作用する排風機３３を設けている。そして、各貯留ビンＤの上部側の穀物投入口に供給用コンベア６８を設け、下部の穀物の排出部にはそれを開閉する排出用シャッター３６を設けてある。送風機３２による通流空気を、貯留ビンＤ全ての床部３１に導入する状態と、７個の貯留ビンＤのうちから選択された貯留ビンＤの下方側に導入する状態とに切り換え自在に構成されている。
【００１９】
詳述すると、貯留ビンＤの床部３１と下方側の底部３７との間を隔壁３８により上下二つに仕切り、隔壁３８と底部３７との間を、隔壁３９により貯留ビンＤの並設方向と直交する方向に仕切ってある。隔壁３８の下方に隔壁３９によって仕切られる一方の空間は、送風機３２からの空気を床部３１の下方側から貯留空間に導入するための導風路４２を形成している。
導風路４２を形成する空間と、貯留ビンＤ内において床部３１と隔壁３８とによって仕切られる空間との間には、送風機３２からの送風をその貯留ビン内に供給する連通状態と、送風を遮断する状態とに切り換えるための通風制御用ダンパ４６を設けてある。又、隔壁３８の下方に隔壁３９によって仕切られる一方の空間には、穀粒排出用の横送りコンベア７０を配置してある。
【００２０】
そして、図１６に示すように、貯留ビンＤにおける穀物貯留空間の床部３１は、金属板を打ち抜いて多数の通気孔３１ａを形成するとともに、打ち抜きの際に舌片３１ｂが排出部６９側に延びる状態で形成されるようにして、下方側から供給される空気を上方側に通過させるとともに、排出部６９側に向きを変更して送風するように構成している。
【００２１】
前記各組の７個の貯留ビンＤのうちの３個の貯留ビンの内部の貯留空間には、穀物を上下方向に移動しながら攪拌する攪拌装置１０を設けてある。この攪拌装置１０は、上下方向に沿う軸芯周りで回転しながら前記貯留空間に貯留される穀物を攪拌処理する攪拌スクリュー１１が平面視にて略直交する２方向夫々に移動操作自在に設けられて構成されている。
詳述すると、図１５、図１９、図２０に示すように、支持枠１２にて上下方向に沿う軸芯周りで回転自在に一対の攪拌スクリュー１１が支持されるとともに、この支持枠１２が貯留ビンＤの並設方向（以下、Ｘ方向という）並びにそれと略直交する方向（以下、Ｙ方向という）夫々に沿って移動操作自在に構成されている。つまり、前記支持枠１２に前記Ｘ方向に適宜間隔をあけて一対の攪拌スクリュー１１が上下方向に沿う軸芯周りで回転自在に支持されるとともに、各攪拌スクリュー１１を各別に回転駆動する回転用電動モータＭ１が夫々設けられている。又、前記支持枠１２の上部側ガイド部１２ａが、前記Ｘ方向に沿って設けられる長尺状の支持レール１４にガイドローラ１５にて移動操作自在に支持されるとともに、第１移動用電動モータＭ２の動力が減速機構１６を介して駆動輪１７を駆動することで支持レール１４上をＸ方向に沿って移動するように構成されている。
一方、前記支持レール１４は、長手方向両端側に備えられたガイドローラ１８が前記Ｙ方向に沿って設けられる長尺状の固定ガイドレール１９に転動案内される構成となっており、第２移動用電動モータＭ３の動力が減速機構２０を介してガイドローラ１８を駆動することにより、支持レール１４、支持枠１２、及び、各攪拌スクリュー１１の夫々が一体的に前記Ｙ方向に沿って移動するように構成されている。
【００２２】
従って、この攪拌装置１０は、回転用電動モータＭ１を駆動させて各攪拌スクリュー１１夫々を回転させながら、第１移動用電動モータＭ２及び第２移動用電動モータＭ３を正逆方向に駆動させて、貯留空間Ｄｉの略全域にわたって貯留されている穀物を上下方向に攪拌移動させることができるように構成してある。
【００２３】
尚、前記攪拌装置１０は、修理点検のためのメンテナンス作業を容易に行えるように構成されている。つまり、前記固定ガイドレール１９に沿うように、図示しない点検用の入り口から作業者が入り込んで歩行移動することが可能なようにメンテナンス用の通路ｔｕが形成されるとともに、前記支持枠１２には前記上部側ガイド部１２ａから下方側にむけてハシゴ１２ｂが形成され、その下部には点検用架台１２ｃが連設されている。従って、作業者は、前記通路ｔｕからハシゴ１２ｂを利用して点検用架台１２ｃまで移動し、この点検用架台１２ｃにて前記回転用電動モータＭ１等の点検作業を行えることになる。
【００２４】
そして、各送風機３２、排出用シャッター３６、ダンパ４６、各電動モータ等の作動を制御する制御装置５３と、作動内容を指令する操作盤５４とが備えられ、制御装置５３は、切換スイッチ５４ａにて通風モードが指令されると、図１７に示すように、全ての排出用シャッター３６を閉じ状態とし、選択スイッチ５４ａにて選択された貯留ビンＤに対して通風制御用ダンパ４６を開状態とするとともに、送風機３２、各電動モータを作動させて、通風乾燥が行われる。そして、排出モードが指令されると、図１８に示すように、選択スイッチ５４ｃにて選択された貯留ビンＤの排出用シャッター３６及び通風制御用ダンパ４６のみ開状態として、他の全ての排出用シャッター３６及び通風制御用ダンパ４６を閉じ状態とする。このようにして、送風機３２の通流空気を選択された貯留ビンＤの床部３１の下方側から導入して、その空気によって穀物を排出口側に流動させることにより、貯留ビンＤ内の穀物を全て排出することができる。
【００２５】
次に、上記貯留ビンＤの各穀物の貯留空間Ｄｉを形成するための構成について説明する。上記貯留ビンＤは、図４、図５に示すように、主柱５と梁６を組み付けるとともに、主柱５同士の間の中央において、上下の梁６に対して間柱７を組み付けて、左右方向に並ぶ主柱５と間柱７、及び、上下の梁６にて、パネル取付け用の矩形状の枠部分が区画形成されている。ここで、主柱５と間柱７とによって柱部材５，７が構成され、梁６によって梁部材６が構成され、柱部材５，７と梁６とは、別個に形成されて、設置箇所において組付け自在に構成されている。また、上記主柱５、間柱７及び梁６とは別個に形成されたパネルＰが、上記設置箇所において組付けられた主柱５、間柱７及び梁６にて形成される矩形状の枠部分に対して組付け自在に構成されている。そして、主柱５、間柱７、梁６及びパネルＰが前記設置箇所において組付けられて、それらによって平面視で略四角形状の周壁部が形成されるとともに、前記周壁部にて囲まれる領域に乾燥又は貯蔵のために穀物を貯留する穀物の貯留空間Ｄｉが形成されている。尚、各貯留空間Ｄｉの下方側に、前記乾燥用の送風を行う導風路４２等を配置させるための床枠部ＵＫが形成されている。
【００２６】
ここで、前記枠部分にパネルＰを組み付けた状態では、パネルＰに対しては、上下方向並びに横方向での荷重がほとんどかからず、貯留穀物によるパネル厚さ方向での圧力のみがかかるようにして、後述のように中空状態にして軽量化したパネルＰでも、要求される強度を充分に確保できるようにしてある。尚、隣接して配置された複数の貯留空間Ｄｉ同士で、主柱５、中間柱７、梁６及びパネルＰが共用されている。
【００２７】
次に、図６、図７、図８に基づいて、パネルＰについて説明する。
このパネルＰは、パネル厚さ方向に間隔を隔てて位置して、一対のパネル表面部を形成する一対の矩形状の板状部Ｂを備えて中空状に構成され、上記一対のパネル表面部のうちの少なくとも前記穀物の貯留空間Ｄｉに面するものが、平坦面状に形成されている。この例では、両側に貯留空間Ｄｉが存在するパネルＰのみならず、片側だけに貯留空間Ｄｉが存在するパネルＰについても、一対のパネル表面部の両方を平坦面状に形成しているが、片側だけに貯留空間Ｄｉが存在する場合には、その貯留空間Ｄｉに面する側のパネル表面部のみを平坦面状に形成するようにしてもよい。
そして、パネルＰは、後述するような３個の中空のパネル構成体Ｔ１，Ｔ２，Ｔ３を互いに溶接接続して全体として中空の矩形状となるように構成されている。つまり、前記３個の角筒状体Ｔ１，Ｔ２，Ｔ３夫々は、板状材の外周部を横断面形状が略コの字形になるように屈曲成形した一対の板状部成形材１同士を、前記矩形状の板状部Ｂを構成する平坦状のパネル形成面１ａが外方側に位置する状態で張り合わせて、中空状になるように構成されている。
【００２８】
板状部成形材１の外周部を横断面形状が略コの字形になるように屈曲成形して屈曲部１ｂと鍔部１ｃとで形成される内部空間に、縦方向に３個、横方向に１個の断面形状が略Ｌ形の補強材２を、適宜間隔をあけて配置して溶接接続してあり、板状部成形材１に補強材２を溶接した状態では、補強材２の外方側の面が板状部成形材１の鍔部１ｃの外方側の面と略同一面を形成するとともに、補強材２が板状部成形材１の両側の鍔部１ｃ間の略全長にわたる状態となるようにしてある。
そして、一対の板状部成形材１を、夫々の鍔部１ｃ同士、補強材２同士を夫々を当付けた状態で対向させて、一対の板状部成形材１夫々の屈曲部１ｂ同士を溶接接続してパネル構成体Ｔ１，Ｔ２，Ｔ３を構成して、それらの夫々のパネル構成体Ｔ１，Ｔ２，Ｔ３同士をパネル幅方向に密接状態に並べ、隣合うもの同士を溶接接続して、１枚の矩形中空状のパネルを構成してある。
【００２９】
このとき、パネルＰは、矩形形状の四隅に対応する角部夫々において、パネルＰの一部を欠除する形状として、その欠除した部分において、パネルＰの外周部から外方側に向けて突出するように固定状態で取付け用板材７１が設けられる構成としている。
つまり、３つのパネル構成体Ｔ１，Ｔ２，Ｔ３のうち中央部のパネル構成体Ｔ２を除く両側のパネル構成体Ｔ１，Ｔ３における板状部成形材１は、パネル角部に対応する箇所が傾斜状態になるように設けられて四隅の角部を欠除するような状態で屈曲形成されている。従って、この欠除部分Ｋにおけるパネル外周部も、その他の外周部と同様に、前記屈曲部１ｂにより平坦面状に形成されている。そして、この欠除部分Ｋにおけるパネル外周部に、略三角形状の１枚板構造の取付け用板材７１がほぼ直角に溶接された取付け用の台座７２を溶接固定する構成とし、前記取付け用板材７１がパネルＰの外周部から外方側に向けて突出するように固定状態で設けられる構成となっている。この取付け用板材７１は、組付けた状態では、後述するように、主柱５、梁６及びパネルＰ夫々によって囲まれる隅部の略直角三角形状の領域に位置することになるが、主柱５や中間柱７と梁６との連結点に近い箇所が欠除される形状にて構成されるとともに、複数のボルト挿通孔７３が形成されている。
【００３０】
尚、前記パネルＰは、補強材２を縦方向並びに横方向に略等間隔で並設してあり、そのことによって、パネル幅方向の全体において同じ強度になるように補強するように構成してある。上記補強材２の個数は必要とする強度に応じて適宜変更してもよい。又、パネル構成体Ｔ１，Ｔ２，Ｔ３は、横断面形状が偏平長方形状となる偏平状に形成してあり、そのような偏平状のパネル構成体を用いることにより、パネルＰを形成するための構成体の個数を少なくして、コストダウンを図っている。
【００３１】
又、中空状のパネルＰの内部空間のうちで、取付け用板材７１が固定される角部に対応する箇所には、パネルＰの厚さ方向での強度を補強する補強部材としての補強リブ７４が３個適宜間隔をあけて設けられている。詳述すると、図７（ロ）、図８に示すように、パネルＰの角部に対応する箇所においては、外周部のその他の領域と同様に、上述したように略コの字状に屈曲形成して屈曲部１ｂと鍔部１ｃが形成されるが、この箇所の鍔部１ｃは、他の領域の鍔部１ｃよりも広幅になるように形成されている。そして、このような広幅の鍔部１ｃと屈曲部１ｂとで形成される内部空間に、パネル厚さ方向に沿う状態で、鍔部１ｃ、屈曲部１ｂ、パネル形成面１ａの夫々に対して補強リブ７４が溶接固定される状態で設けられている。
【００３２】
次に、図９〜図１４を参照しながら、柱５，７、梁６、及び、パネルＰの組み付け構造について説明を加える。柱部材としての主柱５や中間柱７、梁部材としての梁６、及び、前記パネルＰの夫々が、別個に形成されて設置箇所において組み付け自在に構成され、主柱５、中間柱７、梁部材６、及び、パネルＰが前記設置箇所において組付けられて、平面視で略四角形状の周壁部が形成され、この周壁部にて囲まれる領域に穀物貯留空間としての貯留空間Ｄｉが形成されるようになっている。
尚、これらの部材が組み付けられる前に、設置箇所には、先ず、最初に、床枠部ＵＫについて、各床用柱部材ｈｕや床面形成用の支持部材８３（この部材は横方向に長く一体形成されるＨ型鋼材が用いられる）等を全ての貯留空間Ｄｉ（２８個分）について予め設置しておく。尚、この作業は低い位置にて簡単に行える。又、この床枠部ＵＫには、上記したような導風路４２や横送りコンベア７０等の設置が行われることになる。そして、上記床枠部ＵＫに主柱５と最下段の中間柱７が予め立設固定状態で取付けられることになる。中間柱７、梁６、パネルＰ等を１個づつ順次下方側から上方側に向けて組み付けていくことで対応できる。このような組み付け作業は、設備の外周側に位置させた状態で高い位置での締結作業を行えるようにするために作業用の足場が組まれることになる。
【００３３】
主柱５は、横断面形状が角型中空状となる角筒材、具体的には、引き抜き加工による市販の角形鋼管が予め工場にて適宜長さに切断して加工された角筒材にて構成され、床枠部ＵＫの上部側から上端部まで上下方向に沿って連なる一体形状として構成されている。
中間柱７は、１枚のパネルＰの縦方向の幅にほぼ対応する長さに形成され、それらを上下方向に連結する構成となっており、長手方向中間部分は、主柱５と同様な、断面形状が角型中空状となる角筒材からなる角筒部７ａにて構成され、長手方向両端側箇所は、断面形状がＨ形の鋼材からなるＨ形部７ｂにて構成され、それらが予め溶接にて連結されて構成されている。
又、梁６は、前記主柱５と中間柱７とを連結するように前記各パネルＰの横方向の幅にほぼ対応する長さに形成され、この梁６も中間柱７と同様に、長手方向中間部分は、主柱５と同様な、断面形状が角型中空状となる角筒材からなる角筒部６ａにて構成され、長手方向両端側箇所は、断面形状がＨ形の鋼材からなるＨ形部６ｂにて構成され、それらが予め溶接にて連結されて構成されている。
【００３４】
次に、上下方向の中間部に位置する連結箇所を例にとって、主柱５、中間柱７、及び、梁６の連結構成について説明する。
図１１に示すように、前記主柱５の外周面に横側方に向けて突出する状態で縦向きの連結板７５が溶接固定され、梁６のＨ形部６ｂにおける内側縦面部分７６と前記連結板７５とをボルト連結することで、主柱５と梁６とが連結される構成としている。主柱５には、前記連結板７５の上下両側に位置させて、横側方、つまり、矩形状の枠部分の内方側に向けて突出する状態で略三角形状に形成された連結用板材としての柱側板材７７が溶接固定される状態で設けられ、又、梁６の主柱側に位置するＨ形部６ｂにおける上下両側部には、上方側及び下方側夫々に向けて、つまり、矩形状の枠部分の内方側に向けて突出する状態で略三角形状に形成された連結用板材としての梁側板材７８が、ネジ式締結手段としてのボルト・ナットの締め付けにより連結固定する状態で設けられている。
主柱５と梁６とが連結された状態では、柱側板材７７と梁側板材７８とが略面一の状態で端縁同士が突き合わされて一枚の連結用の板体と同様に機能するような構成となっており、パネルＰが装着された状態では、パネル側の取付け用板材７１が、これらの柱側板材７７と梁側板材７８とに対して厚み方向に沿って重なるように位置することになる。
このように、柱側板材７７の主柱５や中間柱７に対する取付け、及び、梁側板材７８の梁６に対する取付けのうちの少なくともいずれか一方が、ネジ式締結手段にて行われるように構成されている。
【００３５】
図１２に示すように、前記梁６の中間柱側に位置するＨ形部６ｂと、下側に位置する中間柱７における上部側のＨ形部７ｂとの間は、梁６側のＨ形部６ｂの端部に溶接された板材６８と、中間柱７側のＨ形部７ｂとがボルト連結されている。そして、中間柱７における梁６との連結箇所の下方側には、横側方、つまり、矩形状の枠部分の内方側に向けて突出する状態で略三角形状に形成された連結用板材としての柱側板材７７が溶接固定される状態で設けられ、梁の側のＨ形部６ｂの下部側には、下方側夫々に向けて、つまり、矩形状の枠部分の内方側に向けて突出する状態で略三角形状に形成された連結用板材としての梁側板材７８が、ネジ式締結手段としてのボルト・ナットの締め付けにより連結固定する状態で設けられている。
【００３６】
そして、前記梁６の中間柱側に位置するＨ形部６ｂと、上側に位置する中間柱７における上部側のＨ形部７ｂとの間は、矩形状の枠部分の内方側に向けて突出する状態で略三角形状に形成された連結用板材としての共用形板材７９における直交する２辺に夫々溶接された一対の取付け部材８０を介して互いにボルト締結により連結される構成となっている。つまり、これらの取付け部材８０を介して、梁６と、上側に位置する中間柱７とが連結される構成となっている。
尚、上下両側に位置する中間柱同士は、夫々のＨ形部７ｂの端面に溶接された板材８４、８５同士をボルト・ナットの締め付けにより連結固定する構成としている。
【００３７】
連結用板材としての、柱側板材７７、梁側板材７８、及び、共用形板材７９の夫々には、組付けるときにパネルＰにおける前記取付け用板材７１に形成されたボルト挿通孔７３と連通するような複数のボルト挿通孔８１が夫々形成されている。
【００３８】
そして、パネルＰが組み付けられることになる矩形状の枠部分の内周部における四隅の角部を除く箇所には、パネルＰの外周部が係入される保持部が設けられている。詳述すると、前記主柱５におけるパネルＰが位置することになる横側面のうち前記柱側板材７７が位置する箇所を除く領域、前記中間柱７におけるパネルＰが位置することになる横側面のうち前記共用形板材７９が位置する箇所を除く領域、及び、前記梁６の上下両側の外周面のうち前記梁側板材７８や前記共用形板材７９が位置する箇所を除く領域の夫々に、組み付けられた後においてパネルＰの外周部が係入されて厚み方向両側部を保持することになる前記保持部としての断面形状がコの字形のパネルガイド８２が溶接固定されている。このパネルガイド８２によって前記パネルＰを厚み方向両側部から保持する構成となっている。尚、各パネルガイド８２の主柱５、中間柱７、及び、梁６に対する溶接部分には、コーキング材が塗布され密閉状に封止する構成となっている。
【００３９】
尚、前記パネルＰは、左右両側に位置する主柱５と中間柱７、及び、上下両側の梁６にて区画形成される矩形状の枠部分の内周部に組み付けられることになるが、例えば、その枠部分の一辺（上方側の梁）が開放された状態で、図１４に示すように、枠部分の内周部に設けられた前記パネルガイド８２により、パネルＰの左右両側部における厚み方向両側部が支持された状態で差し込み装着することができる。そして、パネルＰが差し込み装着されると、図５に示すように、パネルの四隅における取付け用板材７１が、前記柱側板材７７、梁側板材７８、及び、共用形板材７９の夫々と、厚み方向に重なる状態で位置することになる。そして、取付け用板材７１の各ボルト挿通孔７３と、前記柱側板材７７、梁側板材７８、及び、共用形板材７９夫々に形成された各ボルト挿通孔８１とにわたってボルトを挿通させてナットで締め付けることで、つまり、ネジ式締結手段にて締結することで、主柱５、中間柱７及び梁６夫々に対してパネルＰを連結固定することができるのである。
このとき、パネルＰの四隅に設けられる取付け用板材７１が、主柱５と梁６との連結点、及び、中間柱７と梁６との連結点に近い箇所が欠除される形状にて構成されていることから、例えば、このような欠除する形状とせずに、ほぼ直角状態に尖っている形状とすれば、主柱５、中間柱７、梁６夫々を連結して組付ける場合に寸法誤差が生じて、取付け用板材７１の先端部が上記連結箇所の隅部分に干渉して適切な組付けができなくなる等のおそれがあるが、上記したように欠除する構成とすることで、このような不都合を回避し易いものとなる。
尚、最下段に位置するパネルＰにおける下方側の外周面が対応する部分は、床枠部ＵＫの支持部材８３（Ｈ形鋼材）の上部面に上記したような保持部８２や梁側板材７８及び共用形板材７９が設けられており、この支持部材８３が梁６として機能することになる。
【００４０】
そして、この穀物貯留設備においては、主柱５、間柱７、梁６及びパネルＰによって平面視で略四角形状に形成される周壁部にて囲まれる領域の内側に、主柱５に位置固定状態で組み付け作業用のハシゴＨａが取付けられている。
つまり、前記周壁部にて囲まれる領域の四隅夫々の角部に対応する位置に、上下方向に設定間隔をあけて並べて前記柱部材５の上下方向のほぼ全長にわたって、主柱５に固定される状態で複数の足置き部材９５が設けられて、これらの複数の足置き部材９５により前記組付け作業用のハシゴＨａが構成されている。
【００４１】
詳述すると、図４、図２１〜図２４に示すように、前記各足置き部材９５は、帯板を略三角形状に屈曲形成して構成され、前記主柱５の貯留空間Ｄｉに臨む角部に上下方向に沿って適宜間隔（例えば、約３０ｃｍ間隔）をあけて溶接固定されている複数の取付板９６夫々にボルト連結にて取付け固定する状態で設けられ、この複数の足置き部材９５が前記各取付板９６に取り付けられ、図２４に示すように、この複数の足置き部材９５により作業者が昇降することができる組み付け作業用のハシゴＨａが形成されることになる。
従って、作業者は、上記したような外側の足場を利用して順次、組み付けられる柱と梁とのネジ締結作業が下側から上側に向けて順次行われることによって、上記したようなハシゴＨａが平面視で略四角形状に形成される周壁部の四隅の夫々に形成されることになる。
そして、設備の内方側に位置する個所において、このハシゴＨａを利用して高い個所にまで登って主柱５や梁部材６とパネルＰとのネジ締結作業を行うことができるのである。中間柱７とパネルＰとの締結作業は、例えば隣り合う主柱５の前記足置き部材同士にわたり載置板を掛け渡して仮の足場として利用して作業を行う等の対応をとることができる。
【００４２】
尚、上記図４、図２１〜図２４においては、略四角形状に形成される周壁部を構成するための部材のみを記載して、それ以外の部材については記載を省略しているが、実際には、設備の内方側に位置する主柱５には、その角筒形状における４個の角部の夫々に上記したようなハシゴＨａが形成されており、周囲の４個の側面に夫々柱側板材７７やパネルガイド８２等が設けられることになる。
又、図２、図３、図５、図９〜図１１の夫々においては、各部材の配置構成を理解し易くするために、前記ハシゴＨａの記載は省略している。
【００４３】
そして、平面視で略四角形状に形成される周壁部の四隅の角部のうちの３個所において、各足置き部材９５の存在空間と貯留空間Ｄとを上下方向ほぼ全域にわたって遮断する仕切り板９７が設けられている。この仕切り板９７は、前記各パネルＰの締結作業が終了して組み付け作業用のハシゴＨａの役目を終えた前記足置き部材９５の足置き用の縦壁部分９５ａ及び梁６にネジ止め固定される状態で取付けられている。従って、平面視で略三角形状に形成される各足置き部材９５の存在空間は、貯留空間Ｄと遮断されており穀物が存在しない領域となる。
上記したような周壁部の四隅の角部は、その領域にも穀物を貯留できるようにすると、図２６に示すように、攪拌スクリュー１１による未攪拌域になってしまうので、上記したように仕切り板９７を設けて貯留空間と遮断することで攪拌されない領域に穀物が貯留されるのを未然に防止できることになる。
【００４４】
前記攪拌スクリュー１１による未攪拌域としては、平面視にて周壁部の四隅の角部に対応する個所だけでなく、図２７に示すように、側面視における下端側の角部においても攪拌されない領域が生じるので、上記縦方向の仕切り板９７と同様に、図２５に示すように、斜め姿勢の横方向の仕切り板９８を設けて、貯留空間と遮断することで攪拌されない領域に穀物が貯留されるのを未然に防止するようにしている。
【００４５】
尚、周壁部の四隅の角部のうちの残りの一つの角部においては、組み立て作業が終了した後も前記ハシゴがそのままハシゴとして利用することができるように設けられている。これは、この設備が使用された後に、例えば、床面の清掃等のメンテナンスや点検作業等を行うために作業者が昇降するためのものである。この個所においては、前記パネルＰのネジ締結個所は、足置き部材９５と主柱５との間に設けられたカバー体９９にて貯留空間と遮断するようにして、穀物を排出させた後に前記ネジ締結部分に穀物が残留するのを防止するようにしている。

TECHNICAL FIELD OF THE INVENTION
In the present invention, a plurality of pillar members, a plurality of beam members connecting the adjacent pillar members to each other, and a panel formed in a hollow rectangular shape form a substantially square peripheral wall portion in plan view. In addition, the panel is configured to be assembled to the inner peripheral portion of a rectangular frame portion defined and formed by the column member and the beam member, and to be dried or stored in a region surrounded by the peripheral wall portion. The present invention relates to a grain storage facility in which a grain storage space for storing grains is formed.
[0002]
[Prior art]
Conventionally, as the grain storage facility having the above configuration, for example, as shown in JP-A-11-313534, the plurality of column members and the plurality of beam members are assembled by screw-type fastening means, and A frame-shaped frame is provided on the inner peripheral portion of a rectangular frame defined by the member and the beam member, and a screw-type fastening means is provided around the panel along the panel thickness direction with the frame. There was one that was configured to be assembled. The grain storage space configured in this way will be tall in order to store a large amount of grain carried in by the producer in as little space as possible, and, for example, to store grains of a plurality of producers. In general, a plurality of grain storage spaces are formed in a state where adjacent grain storage spaces share a side wall portion so that the grain storage spaces can be stored in a state of being separately managed.
[0003]
And when assembling a grain storage facility which is such a large facility at an installation location, a plurality of column members and a plurality of beam members are sequentially assembled with a screw type fastening means, and the column member and the beam member are combined. The panel is sequentially assembled to the inner peripheral portion of the rectangular frame section formed by the partitioning, but when performing the fastening work by the screw type fastening means, it is easy to perform the work when performing at a low position close to the ground. However, when performing a fastening work at a high place, since the work cannot be performed from the ground as it is, for example, as described above using an assembling type scaffold prepared separately from each of the above-described members. Fastening work had to be performed.
That is, the outer scaffold is assembled so as to be located on the outer peripheral side of the grain storage facility, and the inner scaffold is located in the inner space with respect to the grain storage space located on the inner side of the grain storage facility. Are assembled, using the outer scaffold to sequentially assemble the pillar members, beam members, panels, etc. located on the outer peripheral side by screw-type fastening means, and to the inner side of the grain storage space located on the inner side. Column members, beam members, panels, and the like are sequentially assembled by screw-type fastening means.
[0004]
[Problems to be solved by the invention]
In the case of performing the fastening work using the assembled scaffold as described above, the outer scaffold and the inner scaffold must be prepared, respectively, but when the inner scaffold is prepared, However, it is difficult and troublesome work to form a scaffold inside the peripheral wall section partitioned into a substantially square shape, and to remove the scaffold after the assembling work is completed. In particular, when the number of grain storage spaces increases, the work of preparing and removing such scaffolds increases, and there is a disadvantage in that the efficiency of the assembling work as a whole facility is reduced.
[0005]
The present invention has been made in view of such a point, and an object of the present invention is to provide a grain storage facility capable of performing assembling work as efficiently as possible.
[0006]
[Means for Solving the Problems]
According to the characteristic configuration of the first aspect, the plurality of pillar members, the plurality of beam members that connect the adjacent pillar members, and the panel formed in a hollow rectangular shape have a substantially square shape in plan view. A peripheral wall portion having a shape is formed, and the panel is configured to be assembled to an inner peripheral portion of a rectangular frame portion defined and formed by the column member and the beam member, and is surrounded by the peripheral wall portion. In a grain storage facility in which a grain storage space for storing grain for drying or storage is formed in an area, a ladder for assembling work in a fixed state on the peripheral wall, inside an area surrounded by the peripheral wall. Is installed.
[0007]
When assembling each of the column member, the beam member, and the panel, for example, an outer scaffold is assembled on the outer peripheral side of the facility, and the assembling work of the column member and the beam member is performed by using the outer scaffold. Will be performed sequentially from the lower side to the upper side, but a ladder for the assembling work will be mounted in a fixed position inside the area surrounded by the substantially rectangular peripheral wall in plan view Therefore, the ladder provided inside the peripheral wall portion is formed by sequentially performing the assembling work as described above.
Therefore, even in a case where the panel is assembled to a rectangular frame portion defined and formed by the column member and the beam member at a high place, the worker can provide a dedicated scaffolding in the internal space of the peripheral wall portion, By using the ladder provided inside the peripheral wall portion, the panel can be moved to a high place to perform a panel fastening operation.
[0008]
Therefore, as the scaffold for the assembling work, it is only necessary to assemble the outer scaffold located on the outer peripheral side of the equipment, and it is not necessary to provide an inner scaffold which makes the preparation and removal of the scaffold cumbersome, and the assembling work is not required. It has become possible to provide grain storage facilities that can be performed as efficiently as possible.
In addition, a stirring screw that stirs the grains stored in the grain storage space while rotating about an axis extending along the vertical direction is movably provided in each of two directions substantially orthogonal to each other in a plan view, and the peripheral wall is provided with a stirring screw. The ladder for the assembling work is configured at a position corresponding to each of the four corners in plan view in the area surrounded by the part, and the ladder existence space and the grain storage space for the assembling work are A partition plate is provided to block almost all areas in the vertical direction.
Although the stirring screw rotating around the axis along the vertical direction is moved and operated in two directions substantially orthogonal to each other in a plan view, the stirring processing is performed on the grains stored in the grain storage space. In addition, the stirring screw is moved so that the unstirred area does not occur as much as possible with respect to the grain stored in the grain storage space. However, since the peripheral wall forming the grain storage space as described above is provided in a substantially square shape in plan view, at a position corresponding to each of the four corners in plan view of the area surrounded by the peripheral wall, for example, As shown in FIG. 26, due to its structure, an unstirred region where stirring by the stirring screw cannot be performed occurs. Therefore, since the ladder for the assembling work is configured at each of the four corners which are such unstirred areas, the ladder for the assembling work is arranged at a reasonable position without obstructing the stirring process by the stirring screw. Ladder will be provided.
In addition, since a partition plate is provided to block the existing space of the ladder for the assembling work and the grain storage space over substantially the entire vertical direction, the ladder for the assembling work does not exist inside the grain storage space. It is possible to avoid the disadvantage that the grain is placed and remained on the upper surface of the ladder for the assembling work after the grain is carried out, and the stirring is performed by blocking the corner portion that becomes the unstirred area by the stirring screw with the partition plate. The grain that is not produced can be reduced as much as possible.
[0009]
According to the characteristic configuration described in claim 2, in claim 1, the panel has a shape in which each corner corresponding to the four corners of the rectangular frame portion is cut off, The rectangular frame is formed by providing a mounting plate in a state protruding outward from an outer peripheral portion, at positions corresponding to four corners of the rectangular frame portion of each of the column member and the beam member. A connecting plate is provided in a state protruding inward of the portion, and the mounting plate and the connecting plate are screwed along the thickness direction in a state where the connecting plate and the connection plate are overlapped in their respective thickness directions. Then, the panel is connected and fixed to each of the column member and the beam member.
[0010]
A panel formed in a hollow rectangular shape has a shape in which each of the corners corresponding to the four corners of the rectangular frame portion is cut off, and the cutout portion projects outward from the outer peripheral portion of the panel. The mounting plate is provided in a state in which the mounting plate is provided, and the connecting plate is provided on the column member or the beam member so as to protrude inward of the frame portion, and the mounting plate and the connecting plate are arranged along the thickness direction. The connection between the panel and the column member or the beam member is performed by tightening with a screw.
For example, even if the entire panel is formed into a hollow rectangular shape with a thin plate in order to reduce the weight, the mounting plate does not need to have a thin structure as in the case of the panel plate, and is sufficient. It is possible to use a plate having a thickness having a high strength.
[0011]
Therefore, by adopting a configuration in which the screw fastening portions of the panel are provided at the corners of the four corners, the screw fastening operation is made as easy as possible as compared with a configuration in which the screw fastening portions of the panel are provided over the entire outer peripheral portion of the panel. Even if it can be performed, and even if it adopts a configuration in which the plate material constituting the hollow rectangular panel is made thinner and lighter, a sufficient amount of screws can be fastened to the column members and beam members. It can be configured to have a supporting strength, so that it has excellent durability, and a means suitable for implementing claim 1 can be obtained.
[0012]
According to the feature configuration described in claim 3, in claim 1 or 2,A plurality of footrest members are provided so as to be fixed to the pillar members over substantially the entire length of the pillar members in the vertical direction at a set interval in the vertical direction, and the plurality of footrest members are used for the assembling. A ladder for work is configured.
[0013]
In a state where a plurality of footrest members constituting the ladder for the assembling work are fixed to the column membersWill be provided.
[0015]

In a protruding state, the common plate 79 serving as a connection plate, which is formed in a substantially triangular shape, is connected to each other by bolts via a pair of mounting members 80 welded to two orthogonal sides, respectively. . That is, the beam 6 and the intermediate column 7 located on the upper side are connected via these mounting members 80.
In addition, the intermediate pillars located on the upper and lower sides are configured to connect and fix the plate members 84 and 85 welded to the end surfaces of the respective H-shaped portions 7b by tightening bolts and nuts.
[0037]
Each of the column-side plate 77, the beam-side plate 78, and the common-use plate 79 serving as a connection plate communicates with a bolt insertion hole 73 formed in the mounting plate 71 in the panel P when assembled. A plurality of such bolt insertion holes 81 are respectively formed.

Therefore, the worker uses the outer scaffold as described above to sequentially perform the screw fastening work between the column and the beam to be assembled from the lower side to the upper side, so that the ladder Ha as described above is formed. It is formed at each of the four corners of the peripheral wall portion formed in a substantially square shape in plan view.
Then, at a location located on the inner side of the facility, the ladder Ha can be used to climb to a high location to perform a screw fastening operation between the main column 5 or the beam member 6 and the panel P. The fastening work between the intermediate pillar 7 and the panel P can be performed, for example, by performing a work using a temporary scaffolding by laying a mounting plate over the footrest members of the adjacent main pillars 5. .
[0042]
In FIGS. 4 and 21 to 24, only members for forming the peripheral wall formed in a substantially square shape are described, and the description of other members is omitted. In the main pillar 5 located on the inner side of the equipment, the ladder Ha as described above is formed at each of the four corners in the rectangular tube shape, and is formed on each of the four surrounding sides. The column side plate 77 and the panel guide 82 are provided.
Also, in each of FIGS. 2, 3, 5, and 9 to 11, description of the ladder Ha is omitted in order to facilitate understanding of the arrangement of each member.

It is installed in the state where it is. Therefore, the existence space of each footrest member 95 formed in a substantially triangular shape in a plan view is an area that is isolated from the storage space D and does not include grain.
If the corners of the four corners of the peripheral wall as described above can store grain in that area, as shown in FIG. 26, the area becomes an unstirred area by the agitating screw 11, so that the partition is divided as described above. By providing the plate 97 and blocking it from the storage space, it is possible to prevent grain from being stored in an area that is not stirred.
[0044]
As the unstirred region by the stirring screw 11, not only the portions corresponding to the four corners of the peripheral wall portion in plan view, but also, as shown in FIG. 25, similarly to the vertical partition plate 97, as shown in FIG. 25, a horizontal partition plate 98 is provided in an oblique posture, and the grain is stored in an area that is not stirred by being shut off from the storage space. To prevent this from happening.
[0045]
The remaining one of the four corners of the peripheral wall is provided so that the ladder can be used as a ladder even after the assembly operation is completed. This is for allowing the worker to go up and down after this equipment is used, for example, for maintenance such as cleaning of the floor surface, inspection work, and the like. At this point, the screw fastening part of the panel P is cut off from the storage space by a cover body 99 provided between the footrest member 95 and the main pillar 5, and after discharging the grain, The grain is prevented from remaining on the screw fastening part.
