Description

【0001】
【発明の属する技術分野】
本発明は、建設副産物の搬送積込み方法およびその実施に使用する搬送積込み装置に関する。
【0002】
【従来の技術】
建設工事における揚土作業は、バックホーやクラムシェルなどの建設機械あるいは垂直ベルトコンベア等の連続揚土装置を使って行われている。なかでも、垂直ベルトコンベア等の連続揚土装置は掘削土砂を大量に搬送することが可能である。特許文献1では、掘削土砂を垂直搬送するベルトコンベアの改良が施されている。また、特許文献2では、揚重作業と揚土作業を行えるように、クレーンとクラムシェルを支持枠体上に取り付けた装置が示されている。
一方、コンクリートガラなどの建設廃棄物の垂直搬送は、モッコや底開きバケットを用いて行われている。
【0003】
建築工事では、工期の短縮を図るため、1階の床工事を最初に行い、その後、地下工事と地上工事を並行して行う逆打ち工法が採用されることがある。この逆打ち工法において地下工事で発生する掘削土や建設廃棄物を搬出する場合、地下工事と地上工事を並行して行う関係上、地上階の躯体、特に上階の梁や床スラブによって建設機械の上方作業空間が制限されることになる。また、百貨店等の地下改修工事や免震レトロフィット工事においては、営業を行いながらの工事を余儀なくされる場合があるため、一つの階の限られた領域しか作業領域として確保できないことがある。このような空頭制限下では、建設機械による作業は大きな制約を受け、掘削土や建設廃棄物などの建設副産物の搬出作業能率は大きく低下する。このような状況に対して、特許文献3では、揚重機のキャタピラの両側に着脱自在な増重ブロックを取り付けることで、比較的小型の揚重機でも安定して揚土・揚重が可能になることが示されている。
【0004】
一方、特許文献4では、収納ボックスの底部に設けられた開閉扉を、機械手段によって所望の特定位置で確実に自動閉塞でき、収容物を特定位置以外に落下させることなく好適に排出できる搬送装置が示されている。

【発明が解決しようとする課題】
特許文献3に記載された発明は、小型の揚重機を使用することを前提としているため、搬送積込み能率が低いうえ、小型揚重機を多数使用する必要が生じ、コストが嵩むものとなる。
本発明は、上述する問題点に鑑みてなされたもので、作業空間が制限された場合における建設副産物の搬送積込み作業を、低コストで、且つ、効率良く行うことを目的とする。
【0007】
【課題を解決するための手段】
前記目的を達成するため、本発明に係る建設副産物の搬送積込み方法では、底部に開閉扉を有する箱体と、当該箱体を搬送するための垂直搬送路と、当該箱体を搬送するための水平搬送路とを備える建設副産物の搬送積込み装置を使用し、底部に開閉扉を有する前記箱体に、積込み手段を用いて建設副産物を第一の位置で積込み、前記箱体を第一の位置から第二の位置へ前記搬送路を介して搬送し、当該第二の位置において、前記箱体の底部に設けられた開閉扉を開閉することにより前記箱体内の建設副産物が他の搬送手段に積込まれることを特徴とする。
ここで、建設副産物は、掘削土およびコンクリートガラ等の建設廃棄物の総称であり、搬送路は、ガイドレールなどのように一定の軌道を有するとともに、部材を継ぎ足すことにより軌道を延長することができるものをいう。
また、積込み手段には、バックホーやフォークリフト等の建設機械および後述する積込み装置を使用し、他の搬送手段には、ダンプカー等の搬送車両あるいは他の建設副産物の搬送積込み装置を使用する。
本発明によれば、垂直搬送路および水平搬送路を介して、建設副産物を積載した箱体を搬送するため、作業空間が限られている場合においても、建設副産物の搬送積込み作業を効率良く行うことができる。また、箱体の底部に開閉扉が設けられているため、箱体を逆さにひっくり返すことなく、箱体の底部の開口から建設副産物をダンプカー等の他の搬送手段に積込むことができる。さらに、建設副産物の搬送積込み装置が低価格であり、コスト削減に寄与することができる。
あるいは、本発明に係る建設副産物の搬送積込み方法では、底部に開閉扉を有する前記箱体と、当該箱体を搬送するための垂直搬送路と、当該箱体を搬送するための水平搬送路とを備える建設副産物の搬送積込み装置を、対向若しくは並列して配置し、当該搬送積込み装置が協働して建設副産物を他の搬送手段に積込んでもよい。
本発明によれば、対向若しくは並列して配置した搬送積込み装置を使用して建設副産物を他の搬送手段に協働して積込むため、作業能率が向上する。
また、本発明に係る建設副産物の搬送積込み方法では、前記積込み手段が、建設副産物の落下を防止するために外周に立ち上がり部を設けたコンベアと、当該コンベアを前後に移動させる台とを備える自走式の台車であってもよい。以下、当該自走式の台車を積込み装置と呼ぶ。
建設副産物が発生する地点から搬送路が設置されている地点まで距離が離れている場合、バックホー等による建設副産物の積込み作業能率は低下する。しかし、本発明によれば、バックホー等で前記積込み装置に建設副産物を積込んだ後、前記積込み装置が、搬送路が設置されている地点まで自走し、当該搬送路を介して移動する箱体に建設副産物を積込むので作業能率が向上する。
また、前記搬送路は、無端状の循環搬送路であってもよい。この際、無端状の前記循環搬送路には、底部に開閉扉を有する前記箱体が複数台備えられていることが好ましい。
本発明によれば、無端状の循環搬送路に前記箱体を複数台備えることにより、建設副産物の積込み作業および搬送・搬出作業を並行して行うことができる。
また、底部に開閉扉を有する前記箱体は、前記搬送路に着脱可能であってもよい。この場合には、フォークリフト等を用いて前記箱体の移動・着脱を行う。
また、前記建設副産物の搬送積込み装置は、前記搬送路に搬送路部材を挿入して前記搬送路を延長できるものであってもよい。
本発明によれば、現場の状況に合わせて搬送路を延長することができるため、本発明に係る建設副産物の搬送積込み方法および搬送積込み装置の適用範囲を拡大することができる。
【0008】
【発明の実施の形態】
以下、本発明の実施形態を図面を参照して説明する。
図1は、地下階で発生する建設副産物を地上階へ搬出する作業を、本発明に係る建設副産物の搬送積込み方法によって行う場合の第一実施形態を示したものである。この図に示すように、本実施形態による建設副産物の搬送積込み方法では、底部に開閉扉を有する箱体2と、箱体2を搬送するための垂直搬送路1Vと、箱体2を搬送するための水平搬送路1Hとを備えた建設副産物の搬送積込み装置21を使用する。
図1(a)に示すように、バックホー3等の積込み手段により、地下階で発生する建設副産物は、スラブに設けられた開口部を貫通する、一対のガイドレールからなる垂直搬送路1Vの基礎上で待機する箱体2に積込まれる。次に、図1(b)に示すように、建設副産物を積載した箱体2は、モーター等の駆動手段により垂直搬送路1Vから水平搬送路1Hを介して、ダンプカー4等の他の搬送手段が待機する地上階へ移動する。ここで、水平搬送路1Hを支持する支柱間の距離は、当該支柱間にダンプカー等が停止できる距離を確保する必要がある。箱体2は、地上階のダンプカー4が待機する位置まで移動すると、箱体2に設けられた延設部が、水平搬送路1H上又は水平搬送路1Hに係合する部材上に設けられた第一係止部材に当接することにより、箱体2底部に設けられた開閉扉が機械的に開かれ、箱体2内の建設副産物がダンプカー4へ投下される。その後、箱体2に設けられた延設部が、水平搬送路1H上又は水平搬送路1Hに係合する部材上に設けられた第二係止部材に当接することにより、箱体2底部の開閉扉は機械的に閉じられ、箱体2は、水平搬送路1Hから垂直搬送路1Vを介して、バックホー3が稼動している位置へ戻るものである。
本実施形態による建設副産物の搬送積込み方法では、垂直搬送路1Vおよび水平搬送路1Hを介して、建設副産物を積載した箱体2を搬送するため、作業空間が限られている場合においても、建設副産物の搬送積込み作業を効率良く行うことができる。また、箱体2の底部に開閉扉が設けられているため、箱体2を逆さにひっくり返すことなく、箱体2の底部の開口から建設副産物をダンプカー4等の他の搬送手段に積込むことができる。さらに、建設副産物の搬送積込み装置21が低価格であり、コスト削減に寄与することができる。
【0009】
次に、本発明の他の実施形態について説明する。なお、以降の図においても、建設副産物の搬送積込み方法の第一実施形態と同一の構成要素には同一の符号を用いて説明を省略する。
図2は、本発明に係る建設副産物の搬送積込み方法の第二実施形態を示すもので、図1と同様に、地下階で発生する建設副産物を地上階へ搬出する作業を示したものであるが、建設副産物が発生する地点と搬送路が設置されている地点とが離れている場合を想定している。この図に示すように、本実施形態による建設副産物の搬送積込み方法では、底部に開閉扉を有する第一箱体2aおよび第二箱体2bと、第一箱体2aおよび第二箱体2bを所定位置から別の所定位置へ循環搬送する無端状の搬送路5とを備えた建設副産物の搬送積込み装置22と、積込み装置6とを使用する。
図2(a)に示すように、建設副産物が発生する地下階では、バックホー3が建設副産物を積込み装置6に積込む。建設副産物を積載した積込み装置6は、建設副産物が発生する地点から循環搬送路5が設置されている地点まで自走し、循環搬送路5に備えられた第一箱体2aに建設副産物を積込む。一方、循環搬送路5上の建設副産物を積載した第二箱体2bは、循環搬送路5を介して、地上階のダンプカー4が待機している地点まで移動する。次に、図2(b)に示すように、建設副産物を積載した第一箱体2aは、循環搬送路5を介して、地上階のダンプカー4が待機している地点まで移動する。一方、建設副産物を積載した第二箱体2bは、ダンプカー4の頭上で、第二箱体2b底部の開閉扉を機械的に開閉して建設副産物をダンプカー4に投下した後、循環搬送路5を介して、地下階のバックホー3が稼動している地点まで移動する。
本実施形態による建設副産物の搬送積込み方法では、無端状の循環搬送路5を介して移動する第一箱体2aと第二箱体2bとを利用することにより、建設副産物の積込み作業および搬送・搬出作業を並行して行うことができる。
あるいは、箱体2a、2bを循環搬送路5に着脱可能とした場合には、積込み装置6に代えてフォークリフト等を使用して、建設副産物を積載した箱体2a、2bを移動するとともに、箱体2a、2bを循環搬送路5に着脱する。
なお、本実施形態では、無端状の循環搬送路5上に箱体2を二台備えているが、さらに多く備えていてもよい。
また、本実施形態においても、第一実施形態と同様に、無端状の循環搬送路5ではなく、箱体2を往復させる搬送路1を適用できることはいうまでもない。
【0010】
図3は、本発明の第三実施形態を示すものである。この図に示すように、本実施形態による建設副産物の搬送積込み方法では、第一建設副産物搬送積込み装置23および第二建設副産物搬送積込み装置24を対向して配置して使用する。
第一建設副産物搬送積込み装置23では、積込み手段を用いて、第一箱体2aに建設副産物を積込み、建設副産物を積載した第一箱体2aは第一搬送路1aを介して移動し、地上階のダンプカー4に第一箱体2a内の建設副産物を投下する。一方、第二建設副産物搬送積込み装置24も、第一建設副産物搬送積込み装置23と同様に、積込み手段を用いて、第二箱体2bに建設副産物を積込み、建設副産物を積載した第二箱体2bは第二搬送路1bを介して移動し、地上階のダンプカー4に第二箱体2b内の建設副産物を投下するものである。
本実施形態による建設副産物の搬送積込み方法では、第一建設副産物搬送積込み装置23および第二建設副産物搬送積込み装置24を使用して建設副産物を他の搬送手段に協働して積込むため、作業能率の向上が図れる。
なお、本実施形態においても、第二実施形態と同様に、箱体2a、2bをそれぞれ往復させる搬送路1a、1bではなく、無端状の循環搬送路5を使用して当該搬送路5上に箱体2を複数台備えていてもよい。
また、箱体2a、2bを搬送路1a、1bに各々着脱可能とすることもでき、その場合は、フォークリフト等を使用して、箱体2a、2bを移動するとともに、箱体2a、2bを搬送路1a、1bに着脱する。
【0011】
図4は、本発明に係る積込み装置を示すものである。本発明に係る積込み装置6は、建設副産物の落下を防止するために外周に立ち上がり部8を設けたコンベア7と、コンベア7を前後に移動させる台10とを備えた自走式の台車11である。
先ず、バックホー等により、外周に立ち上がり部8を設けたコンベア7上に建設副産物9が積込まれる。建設副産物9の積載が完了すると、台車11は、搬送路に備えられた箱体のある位置まで自走する。台車11が、当該箱体が設置されている位置に到着すると、コンベア7から当該箱体内へ建設副産物9を投下できる位置まで、台10が前方に移動する。台10の移動が完了すると、コンベア7が稼動し、コンベア7上の建設副産物9が前記箱体内へ投下される。建設副産物9の前記箱体内への投下が完了すると、コンベア7は稼動停止し、台10が後方へ移動する。そして、台車11は、建設副産物9を再び積込むためにバックホー等が稼動している地点に自走する。
建設副産物が発生する地点から搬送路が設置されている地点まで距離が離れている場合、バックホー等による建設副産物の積込み作業の能率は低下する。しかし、本発明に係る積込み装置6によれば、バックホー等で積込み装置6に建設副産物9を積込んだ後、積込み装置6が搬送路が設置されている地点まで自走し、当該搬送路を介して移動する箱体に建設副産物9を積込むので、作業性が向上する。
【0012】
図5は、搬送路の延長が可能な建設副産物の搬送積込み装置を用いて搬送路を延長する第一の方法を示すものであり、地上階において搬送路部材を挿入するものである。本発明に係る建設副産物の搬送積込み装置25は、底部に開閉扉を有する箱体2と、箱体2を搬送するための垂直搬送路1Vと、箱体2を搬送するための水平搬送路1Hとに加えて、垂直搬送路1Vおよび水平搬送路1Hに係合して垂直搬送路1Vを昇降させるための索状体12aと、索状体12aの長さを制御することにより垂直搬送路1Vを昇降させる搬送路昇降装置12と、垂直搬送路1Vに搬送路部材13aを挿入する装置13とを備えている。
次に、建設副産物の搬送積込み装置25を用いて搬送路を延長する方法について説明する。
図5(a)に示すように、垂直搬送路1Vおよび水平搬送路1Hに係合して垂直搬送路1Vを昇降させるための索状体12aを緊張させた後、搬送路部材13aを挿入する上端で垂直搬送路1Vを切り離す。この際、切り離された垂直搬送路1Vが落下しないようにするため、索状体12aを緊張する必要がある。次に、図5(b)に示すように、搬送路部材13aが挿入できるように、搬送路昇降装置12を介して索状体12aを緩め、切り離された垂直搬送路1V間に空間を確保する。その後、図5(c)に示すように、搬送路部材13aを挿入する装置13をスライドさせて、切り離された垂直搬送路1V間の空間に搬送路部材13aを挿入する。最後に、図5(d)に示すように、切り離された垂直搬送路1Vと搬送路部材13aとが接合できる位置まで、搬送路昇降装置12を介して、切り離された垂直搬送路1Vを上昇させた後、切り離された垂直搬送路1Vと搬送路部材13aとを接合する。
建設副産物の搬送積込み装置25は、現場の状況に合わせて垂直搬送路1Vを延長することができるため、本発明に係る建設副産物の搬送積込み方法および搬送積込み装置の適用範囲を拡大することができる。
なお、本実施形態においては、往復式の搬送路1の延長方法について示したが、無端状の循環搬送路5の場合にも、上記と同様の手順により搬送路を延長することができる。
【0013】
図6は、搬送路の延長が可能な建設副産物の搬送積込み装置を用いて搬送路を延長する第二の方法を示すものであり、地下階において搬送路部材を挿入するものである。本発明に係る建設副産物の搬送積込み装置26は、底部に開閉扉を有する箱体2と、箱体2を搬送するための垂直搬送路1Vと、箱体2を搬送するための水平搬送路1Hとに加えて、垂直搬送路1Vの基礎部に設けられた伸縮可能な台14と、垂直搬送路1Vに挿入する搬送路部材13aとを備えている。
次に、建設副産物の搬送積込み装置26を用いて搬送路を延長する方法について説明する。
図6(a)は、建設副産物の搬送積込み装置26の初期状態を示したものである。建設副産物の搬送積込み装置26は、水平搬送路1Hを支持している支柱によって地上階に固定されているが、当該支柱は図中省略している。また、垂直搬送路1Vの基礎部に設けられた伸縮可能な台14の下部周辺は、既に掘削作業が完了した状態にある。
先ず、図6(b)に示すように、垂直搬送路1Vの基礎部に設けられた伸縮可能な台14を伸ばし、台14を地下階に着床させる。次に、図6(c)に示すように、台14を垂直搬送路1Vから切り離した後、台14を下降させ、台14と垂直搬送路1Vとの間に搬送路部材13aを挿入するための空間を確保する。その後、垂直搬送路1Vに持着されている搬送路部材13aを移動し、切り離された垂直搬送路1Vと台14との間に挿入する。最後に、図6(d)に示すように、垂直搬送路1Vと搬送路部材13aと台14とを接合する。
なお、本実施形態においても、往復式の搬送路1の延長方法について示したが、循環搬送路5の場合にも、上記と同様の手順により搬送路を延長することができる。
【0014】
【発明の効果】
以上説明したように、本発明に係る建設副産物の搬送積込み方法および搬送積込み装置によれば、作業空間が制限された場合における建設副産物の搬送積込み作業を、低コストで、且つ、効率良く行うことができる。

[0002]
[Prior art]
The earth unloading work in the construction work is performed using a construction machine such as a backhoe or a clamshell or a continuous earth unloading device such as a vertical belt conveyor. Above all, a continuous earth-lifting device such as a vertical belt conveyor can transport a large amount of excavated earth and sand. In Patent Literature 1, an improved belt conveyor for vertically transporting excavated earth and sand is provided. Patent Document 2 discloses an apparatus in which a crane and a clam shell are mounted on a support frame so that a lifting operation and an earth discharging operation can be performed.
On the other hand, vertical transportation of construction waste such as concrete waste is performed using mokko or bottom-opening buckets.
[0003]
In the construction work, in order to shorten the construction period, there is a case where a reverse construction method in which the floor work on the first floor is performed first, and then the underground work and the ground work are performed in parallel. When carrying out excavated soil and construction waste generated during underground construction in this reverse-casting method, construction machinery on the ground floor, especially beams and floor slabs on the upper floor, is used because construction work is performed in parallel with the underground construction. Work space will be limited. In addition, in underground renovation work and seismic isolation retrofit work in department stores and the like, there is a case where work must be performed while operating, so that only a limited area on one floor can be secured as a work area. Under such headroom restrictions, work by construction machines is greatly restricted, and the work efficiency of carrying out construction by-products such as excavated soil and construction waste is greatly reduced. In such a situation, in Japanese Patent Application Laid-Open No. H11-157, in which a detachable intensifying block is attached to both sides of the caterpillar of the hoist, the earth can be stably lifted and lifted even with a relatively small hoist. It has been shown.
[0004]
On the other hand, in Patent Literature 4, a transfer device capable of automatically closing an opening / closing door provided at the bottom of a storage box at a desired specific position by mechanical means without fail and dropping a stored item to a position other than the specific position can be appropriately discharged. It is shown.
