Description

この発明は、構造物の施工等に際し、重量物を運搬して設置するための台車及びその使用方法に関するものである。 The present invention relates to a trolley for transporting and installing a heavy object and a method of using the trolley when constructing a structure or the like.

近年、高速道路の経年に伴い、高架部分の橋梁の橋桁を取り替える工事が各地で行われているが、都市部においては、図12に示すように、高速道路51の高架橋51aに沿って通行量の多い一般道路52が並行する区間があり、そのような区間では、一般道路52を通行止めにして、長いブームを有する大型のクレーン車を高速道路51の高架橋に横付けした状態で、重量物の撤去や設置等の作業を行うことができない。 In recent years, with the aging of expressways, construction work to replace the bridge girders of elevated bridges has been carried out in various places, but in urban areas, as shown in FIG. 12, traffic volume along the viaduct 51a of the expressway 51. There is a section in which general roads 52 with many roads are parallel, and in such sections, heavy objects are removed with the general road 52 closed and a large crane car with a long boom laid sideways on the viaduct of the highway 51. Or installation work cannot be performed.

このような条件の下で工事を行うため、既存の橋桁の下方で新しい橋桁を地組で組み立て、既存の橋桁を小さく分割して撤去した後、新しい橋桁をジャッキで持ち上げる工法が採用されることがある。 In order to carry out construction under these conditions, a construction method will be adopted in which a new bridge girder is assembled under the existing bridge girder, the existing bridge girder is divided into small pieces and removed, and then the new bridge girder is lifted with a jack. There is.

ところが、この工法によると、新しい橋桁を地組する際、作業現場の上方に既存の橋桁が存在しているため、壁高欄等の重量物を運搬する手段として、やはり大型のクレーン車を使用できず、その対策として、例えば、下記特許文献1に記載されたようなコンパクトな手動アーム式の重量物吊上げ運搬車を使用することが考えられる。 However, according to this construction method, when constructing a new bridge girder, the existing bridge girder exists above the work site, so a large crane vehicle can still be used as a means of transporting heavy objects such as wall railings. Instead, as a countermeasure, for example, it is conceivable to use a compact manual arm type heavy object lifting and transporting vehicle as described in Patent Document 1 below.

特開2001-31383号公報Japanese Unexamined Patent Publication No. 2001-31383

しかしながら、特許文献1に記載された重量物吊上げ運搬車は、金属を主体とする機械の組み立てに使用することを想定したものであり、非常に重いコンクリート製の部材の運搬に適したものではない。 However, the heavy object lifting carrier described in Patent Document 1 is intended to be used for assembling a machine mainly composed of metal, and is not suitable for transporting a very heavy concrete member. ..

そこで、この発明は、大型重機が使用できない現場において、非常に重い部材を安全に運搬して所定の位置に設置できる装置及び方法を提供することを課題とする。 Therefore, it is an object of the present invention to provide an apparatus and a method capable of safely transporting a very heavy member and installing it at a predetermined position in a field where a large heavy machine cannot be used.

上記課題を解決するため、この発明は、箱型枠体が上枠、台枠及び支柱から形成され、前記上枠に、前記台枠の両端直上から張り出すようにレール材が取り付けられ、前記レール材にトロリーが支持されて、前記トロリーにチェーンブロックが備えられ、前記台枠にキャスターが備えられ、
前記トロリーは、前記台枠の一端直上から張り出す位置と他端直上から張り出す位置との間で前記レール材に沿って走行する重量物運搬用台車を提供することとしたのである。
In order to solve the above problems, in the present invention, a box-shaped frame is formed of an upper frame, an underframe, and a support column, and a rail material is attached to the upper frame so as to project from directly above both ends of the underframe. The rail material supports the trolley, the trolley is equipped with a chain block, and the underframe is equipped with casters.
The trolley is intended to provide a trolley for transporting heavy objects that travels along the rail material between a position protruding from directly above one end of the underframe and a position protruding from directly above the other end.

また、前記重量物運搬用台車を使用し、前記レール材に支持されたトロリーが前記台枠の一端直上から張り出す位置にある状態で、重量物を前記チェーンブロックで吊り上げ、
前記レール材に沿って前記トロリーを走行させ、重量物を前記台枠の上方に位置させた後、前記チェーンブロックで重量物を降ろして前記台枠に載置し、
その状態で、前記キャスターの車輪の転動により重量物運搬用台車を重量物の所定の設置場所の付近まで移動させ、
前記チェーンブロックで重量物を前記台枠から吊り上げ、前記レール材に沿って前記トロリーを前記台枠の他端直上から張り出す位置まで走行させ、前記チェーンブロックで重量物を所定の設置場所に降ろす方法を提供することとしたのである。
Further, using the heavy object transporting trolley, the heavy object is lifted by the chain block in a state where the trolley supported by the rail material is in a position of projecting from directly above one end of the underframe.
The trolley is run along the rail material, the heavy object is positioned above the underframe, and then the heavy object is unloaded by the chain block and placed on the underframe.
In that state, the wheels of the casters are rolled to move the heavy load transport trolley to the vicinity of the predetermined installation location of the heavy load.
The chain block lifts a heavy object from the underframe, runs the trolley along the rail material to a position where it projects from directly above the other end of the underframe, and lowers the heavy object to a predetermined installation location with the chain block. We decided to provide a method.

また、その応用として、橋梁における橋桁の取替工事に際し、既存の橋桁の下方で主桁と床版とを組み立てた新たな橋桁の主体部を構築しておき、
前記重量物運搬用台車を新たな橋桁の床版の一側付近に位置づけ、前記床版の他側縁に設置予定の壁高欄を前記重量物運搬用台車よりも前記床版の一側縁寄りに仮置きし、
その状態から、前記重量物運搬用台車を使用する上述の方法により、前記壁高欄を前記床版の他側縁に臨む位置まで運搬して所定の場所に設置する壁高欄の運搬設置方法を提供することとしたのである。
In addition, as an application, when replacing the bridge girder in the bridge, a new main part of the bridge girder that assembles the main girder and the floor slab is constructed below the existing bridge girder.
The heavy load transport trolley is positioned near one side of the new bridge girder floor slab, and the wall balustrade to be installed on the other side edge of the floor slab is closer to one side edge of the floor slab than the heavy load transport trolley. Temporarily placed in
From that state, a method for transporting and installing the wall balustrade by transporting the wall balustrade to a position facing the other side edge of the floor slab and installing the wall balustrade in a predetermined place by the above-mentioned method using the heavy load transport cart is provided. I decided to do it.

この発明に係る重量物運搬用台車では、箱型枠体の上部に取り付けられたレール材が、キャスターを有する台枠の一端及び他端の直上から張り出し、レール材に沿ってチェーンブロックを備えたトロリーが走行する構造となっているので、その使用により、壁高欄のようなコンクリート製の重量物を吊り上げて台枠に載せ、所定の設置場所の付近まで移動させた後、所定の設置場所に吊り降ろすことができる。したがって、大型重機が使用できない現場において、非常に重い部材を安全に運搬して所定の位置に正確に設置できる。 In the heavy load transport trolley according to the present invention, the rail material attached to the upper part of the box formwork protrudes from directly above one end and the other end of the underframe having casters, and a chain block is provided along the rail material. Since the structure is such that the trolley runs, by using it, heavy concrete objects such as wall balustrades are lifted, placed on the underframe, moved to the vicinity of the specified installation location, and then moved to the specified installation location. Can be hung down. Therefore, in a field where a large heavy machine cannot be used, a very heavy member can be safely transported and accurately installed at a predetermined position.

上記のような構成の重量物運搬用台車Cを使用して、図12に示すように、高速道路51の上り線と下り線の並行する高架橋51aについて、それぞれの橋桁の取替工事を行うには、図3に示すように、高架橋51aの橋脚53に沿って支保工21を設置する。 Using the heavy load transport trolley C having the above configuration, as shown in FIG. 12, for the viaduct 51a in which the up line and the down line of the expressway 51 are parallel to each other, the replacement work of each bridge girder is performed. As shown in FIG. 3, the support work 21 is installed along the pier 53 of the viaduct 51a.

次に、図4に示すように、既存の橋桁54の下方の地面に設置した作業用受座22の上で、主桁55aと床版55bとを組み立てて新たな橋桁55の主体部を構築する。 Next, as shown in FIG. 4, the main girder 55a and the floor slab 55b are assembled on the work receiving seat 22 installed on the ground below the existing bridge girder 54 to construct a new main body of the bridge girder 55. do.

そして、図5に示すように、新たな橋桁55の上方に既存の橋桁54が存在するままの状態で、1個当たり3tを超える重量を有する壁高欄Wを、床版55bの両側縁にそれぞれ沿った所定の場所に並べて設置する。 Then, as shown in FIG. 5, with the existing bridge girder 54 still existing above the new bridge girder 55, wall railings W having a weight exceeding 3 tons per piece are placed on both side edges of the deck 55b, respectively. Install them side by side in the designated place along the line.

この作業に際しては、図6に示すように、並行する高架橋51aの間のスペースを利用し、小型のクレーン等により、新たな橋桁55の床版55bの一側付近に重量物運搬用台車Cを載せ、床版55bの一側縁に沿った所定位置に一方の壁高欄Wを設置し、他方の壁高欄Wを床版55bの一側縁と重量物運搬用台車Cの間に仮置きする。 In this work, as shown in FIG. 6, the space between the parallel high bridges 51a is used, and a heavy load carrier C is mounted near one side of the deck 55b of the new bridge girder 55 by a small crane or the like. One wall balustrade W is installed at a predetermined position along one side edge of the floor slab 55b, and the other wall balustrade W is temporarily placed between one side edge of the floor slab 55b and the heavy load carrier C. ..

そして、重量物運搬用台車Cにおいて、トロリー3が台枠12の一端直上から張り出す位置にある状態で、仮置きした壁高欄Wをチェーンブロック4で吊り上げる。その際、チェーンブロック4の荷鎖の下端のフックを、壁高欄Wの頂面の凹所に下部が埋められた吊上ピンの頭部にC字状の吊金具を介して係合させ、荷鎖を巻き上げる(図2参照)。 Then, in the heavy load transporting carriage C, the temporarily placed wall balustrade W is lifted by the chain block 4 in a state where the trolley 3 is in a position of projecting from directly above one end of the underframe 12. At that time, the hook at the lower end of the load chain of the chain block 4 is engaged with the head of the lifting pin whose lower portion is buried in the recess on the top surface of the wall balustrade W via a C-shaped hanging bracket. Wind up the load chain (see Fig. 2).

次に、レール材2に沿ってトロリー3を走行させ、壁高欄Wを台枠12の上方に位置させた後、チェーンブロック4で壁高欄Wを降ろして台枠12の受材12cに載置する。この繰り返しにより、台枠12には、一列に並べる複数個の壁高欄Wを積載する。 Next, the trolley 3 is run along the rail material 2, the wall balustrade W is positioned above the underframe 12, and then the wall balustrade W is lowered by the chain block 4 and placed on the receiving material 12c of the underframe 12. do. By repeating this process, a plurality of wall railings W arranged in a row are loaded on the underframe 12.

なお、キャスター5の車輪は、運搬対象の壁高欄Wの設置予定方向へ向けておくが、高速道路51のカーブ区間に対応して橋桁55が幅方向に傾いている場合には、壁高欄Wの昇降作業に際し、重量物運搬用台車Cが床版55bの低い方へ不意に移動しないように、キャスター5の車輪に沿ってタイヤストッパー23を置いておく。 The wheels of the casters 5 are oriented in the direction in which the wall railing W to be transported is planned to be installed. However, if the bridge girder 55 is tilted in the width direction corresponding to the curved section of the highway 51, the wall railing W A tire stopper 23 is placed along the wheels of the casters 5 so that the heavy load carrying carriage C does not suddenly move to the lower side of the floor slab 55b during the lifting work.

この状態で、キャスター5の車輪の転動により、重量物運搬用台車Cを床版55bの他側縁に臨む壁高欄Wの所定の設置場所の付近まで移動させる。 In this state, the wheels of the casters 5 roll to move the heavy load carrier C to the vicinity of the predetermined installation location of the wall railing column W facing the other side edge of the floor slab 55b.

次に、チェーンブロック4で壁高欄Wを台枠12から吊り上げ、レール材2に沿ってトロリー3を台枠12の他端直上から張り出す位置まで走行させ、チェーンブロック4で壁高欄Wを所定の設置場所に降ろし、その場所に固定する。 Next, the wall balustrade W is lifted from the underframe 12 by the chain block 4, the trolley 3 is run along the rail material 2 to a position where it projects from directly above the other end of the underframe 12, and the wall balustrade W is designated by the chain block 4. Take it down to the place where it is installed and fix it in that place.

そして、キャスター5の向きを変えて、重量物運搬用台車Cを橋桁55の長さ方向に移動させ、壁高欄Wを台枠12から降ろし、床版55bの他側縁に沿って複数個並べる。 Then, by changing the direction of the casters 5, the heavy load carrying carriage C is moved in the length direction of the bridge girder 55, the wall railings W are lowered from the underframe 12, and a plurality of wall rails W are arranged along the other side edge of the floor slab 55b. ..

その後、新たな橋桁55の上方に残存する既存の橋桁54を解体除去する。この作業に際しては、既存の橋桁54の床版54bを撤去し、図7に示すように、主桁54aを切断して小さく分割し、並行する他方の高架橋51aを利用して、細分化された主桁54aを大型のクレーン24により撤去する。 After that, the existing bridge girder 54 remaining above the new bridge girder 55 is dismantled and removed. In this work, the floor slab 54b of the existing bridge girder 54 was removed, and as shown in FIG. 7, the main girder 54a was cut into small pieces and subdivided using the other parallel viaduct 51a. The main girder 54a is removed by a large crane 24.

既存の橋桁54の除去が完了すると、図8に示すように、新たな橋桁55を、支保工21に沿ってジャッキ(図示省略)により所定の高さまで順次上昇させる。 When the removal of the existing bridge girder 54 is completed, as shown in FIG. 8, the new bridge girder 55 is sequentially raised to a predetermined height by a jack (not shown) along the support work 21.

次に、図9に示すように、橋脚53の上方で新たな橋桁55の主桁55a及び床版55bを連結するため、他方の高架橋51aを利用して、トラック25で運び込んだ主桁55a及び床版55bの延長部をクレーン24により橋脚53に載せ、地組みした橋桁55と連結し、主桁55a及び床版55bを橋脚53の間に渡して架設した状態とする。 Next, as shown in FIG. 9, in order to connect the main girder 55a and the deck 55b of the new bridge girder 55 above the pier 53, the main girder 55a and the main girder 55a carried by the truck 25 using the other high bridge 51a. The extension of the deck 55b is placed on the pier 53 by the crane 24, connected to the ground girder 55, and the main girder 55a and the deck 55b are passed between the piers 53 and erected.

さらに、図10に示すように、新たな橋桁55の連結部の床版55bに、他方の高架橋51aを利用してトラック25で運び込んだ壁高欄Wの連結部を、大型のクレーン24により所定の場所に設置する。 Further, as shown in FIG. 10, the connecting portion of the wall railing column W carried by the truck 25 using the other viaduct 51a to the floor slab 55b of the connecting portion of the new bridge girder 55 is designated by a large crane 24. Install in place.

最後に、図11に示すように、新たな橋桁55の床版55bに舗装を行い、路面標示を施工するとともに、作業用の仮設物を撤去すれば、この区間の工事は完了する。 Finally, as shown in FIG. 11, the construction of this section is completed by paving the floor slab 55b of the new bridge girder 55, constructing road markings, and removing temporary objects for work.

このように、上記重量物運搬用台車Cでは、箱型枠体1の上部に取り付けられたレール材2が、キャスター5を有する台枠12の一端及び他端の直上から張り出し、レール材2に沿ってチェーンブロック4を備えたトロリー3が走行する構造となっているので、その使用により、壁高欄Wのようなコンクリート製の重量物を吊り上げて台枠12に載せ、所定の設置場所の付近まで移動させた後、所定の設置場所に吊り降ろすことができる。 As described above, in the heavy load transporting carriage C, the rail material 2 attached to the upper part of the box-shaped frame 1 projects from directly above one end and the other end of the underframe 12 having the casters 5, and is attached to the rail material 2. Since the trolley 3 provided with the chain block 4 runs along the structure, a heavy concrete object such as a wall balustrade W is lifted and placed on the underframe 12 by its use, and is near a predetermined installation location. After moving to, it can be hung at the designated installation location.

なお、上記実施形態では、重量物運搬用台車Cを高架橋51aにおける橋桁の取替工事に使用する場合について例示したが、上記構成の重量物運搬用台車Cは、このような用途に限らず、大型重機が使用できないような条件の現場において、様々な種類の非常に重い部材を安全に運搬して所定の位置に正確に設置することができる。 In the above embodiment, the case where the heavy load transportation carriage C is used for the replacement work of the bridge girder in the viaduct 51a has been illustrated, but the heavy load transportation carriage C having the above configuration is not limited to such an application. In the field where large heavy machinery cannot be used, various kinds of very heavy members can be safely transported and accurately installed in a predetermined position.

また、重量物運搬用台車Cの形態は、運搬する重量物の形状や使用する現場の状況に応じて、適宜変更することができる。 Further, the form of the trolley C for transporting heavy objects can be appropriately changed according to the shape of the heavy objects to be transported and the situation at the site where the heavy objects are used.
