以下に本発明の一実施形態に係る移動式足場１を説明する。図１は、床版の下方空間及び床版が上方にない空間に移動式足場１が設置された状態の桟橋７及びその周辺の構造物の概略を示した平面図である。桟橋７は既設護岸８と渡橋９で連結されている。   A mobile scaffold 1 according to an embodiment of the present invention will be described below. FIG. 1 is a plan view schematically showing a pier 7 and a surrounding structure in a state where the movable scaffold 1 is installed in a space below the floor slab and a space where the floor slab is not above. The pier 7 is connected to the existing revetment 8 and the bridge 9.

以下の説明において、図１における左右方向（桟橋７の長手方向に沿った方向）をＸ方向（右方向を正方向）、上下方向をＹ方向（沖側から岸側に向かう方向を正方向）とする。また、実際の構造物の高さ方向をＺ方向（低い位置から高い位置に向かう方向を正方向）とする。   In the following description, the horizontal direction in FIG. 1 (the direction along the longitudinal direction of the pier 7) is the X direction (the right direction is the positive direction), and the vertical direction is the Y direction (the direction from the offshore side to the shore side is the positive direction). And Moreover, let the height direction of an actual structure be a Z direction (the direction which goes to a high position from a low position is a positive direction).

図２は、移動式足場１が設置された状態の桟橋７の概略を、図１にＡ−Ａ線で示す方向に見た図（Ａ−Ａ矢視図）である。桟橋７は、海底地盤Ｇに根入れされた複数の鋼管杭７１と、鋼管杭７１の杭頭７１１の上に設置された床版７２を備える。図３は、移動式足場１が設置された状態の桟橋７の概略を、Ｙ方向に見た図（正面図）である。なお、実際には、床版７２の下面には格子状に梁が設けられているが、図２及び図３においては梁の図示を省略している。   FIG. 2 is a schematic view (AA view) of the jetty 7 in a state where the mobile scaffold 1 is installed as seen in the direction indicated by the line AA in FIG. The pier 7 includes a plurality of steel pipe piles 71 embedded in the seabed ground G, and a floor slab 72 installed on a pile head 711 of the steel pipe pile 71. FIG. 3 is a schematic view (front view) of the jetty 7 in a state where the mobile scaffold 1 is installed as seen in the Y direction. In practice, beams are provided in a lattice pattern on the lower surface of the floor slab 72, but the illustration of the beams is omitted in FIGS.

図４は、移動式足場１が設置された状態の桟橋７の概略を、図２にＢ−Ｂ線で示す方向に見た図（Ｂ−Ｂ矢視図）である。すなわち、図４は、床版７２直下の桟橋７とその周辺の構造物の概略を示した平面図である。なお、図４においても、床版７２の下面に設けられた梁の図示を省略している。   FIG. 4 is a diagram (BB arrow view) showing an outline of the pier 7 in a state where the mobile scaffold 1 is installed in the direction indicated by the line BB in FIG. That is, FIG. 4 is a plan view schematically showing the pier 7 immediately below the floor slab 72 and the surrounding structures. Also in FIG. 4, illustration of the beams provided on the lower surface of the floor slab 72 is omitted.

図２及び図３に示すように、移動式足場１は、杭頭７１１に取り付けられたブラケット１１と、Ｙ方向が長手方向となるようにブラケット１１に取り付けられた長尺部材である支持部材１２と、Ｘ方向が長手方向となるように支持部材１２の上に配置されたレール１３と、杭頭７１１を挟んで互いに平行に配置された２本のレール１３の間の領域を覆うように支持部材１２の上に配置された足場材１４と、レール１３の上を移動する台車１５と、Ｘ方向において床版７２の下方空間Ｓ1に隣接し床版７２が上方にない空間Ｓ2へと延伸するレール１３を支持するとともに足場を形成するための構造物であるステージ１６を備える。なお、レール１３は支持部材１２の上に配置された足場材１４の上に配置されてもよい。また、ステージ１６は、Ｘ方向における桟橋７の両側に設けられてもよいし、片側のみに設けられてもよい。 As shown in FIGS. 2 and 3, the mobile scaffold 1 includes a bracket 11 attached to the pile head 711 and a support member 12 which is a long member attached to the bracket 11 so that the Y direction is the longitudinal direction. And support so as to cover a region between the rail 13 arranged on the support member 12 so that the X direction becomes the longitudinal direction and the two rails 13 arranged parallel to each other across the pile head 711 the scaffold 14 disposed on the member 12, a carriage 15 that moves on rails 13, the floor plate 72 adjacent the lower space S 1 of the floor plate 72 in the X direction into the space S 2 no upward A stage 16 is provided as a structure for supporting the extending rail 13 and forming a scaffold. The rail 13 may be disposed on the scaffold member 14 disposed on the support member 12. The stage 16 may be provided on both sides of the jetty 7 in the X direction, or may be provided only on one side.

ブラケット１１は、例えば山形鋼であり、長手方向がＺ方向となり、下端部が杭頭７１１の下端から下に突出するように、杭頭７１１の側面にアンカーボルト等により取り付けられている。   The bracket 11 is, for example, angle steel, and is attached to the side surface of the pile head 711 with an anchor bolt or the like so that the longitudinal direction is the Z direction and the lower end portion protrudes downward from the lower end of the pile head 711.

支持部材１２は、例えば溝形鋼であり、例えば１つの杭頭７１１のＹ方向における互いに対向する側面の各々に取り付けられた２本のブラケット１１に、溶接等により取り付けられている。   The support member 12 is, for example, channel steel, and is attached by welding or the like to, for example, two brackets 11 attached to each of the side surfaces of the one pile head 711 facing each other in the Y direction.

レール１３は、例えば溝形鋼であり、例えば開口面が下となる姿勢で、支持部材１２の上に載置された状態で支持部材１２に溶接等により取り付けられている。レール１３は、その大部分が床版７２の下方空間Ｓ1に配置されているとともに、一部は床版７２が上方にない空間Ｓ2に配置されている。 The rail 13 is, for example, channel steel, and is attached to the support member 12 by welding or the like in a state of being placed on the support member 12 with an opening surface facing down, for example. Most of the rail 13 is disposed in the lower space S 1 of the floor slab 72, and part of the rail 13 is disposed in the space S 2 where the floor slab 72 is not located above.

足場材１４は、例えばエキスパンドメタル等の網状板材である。足場材１４のうち、レール１３に沿って台車１５の移動範囲に隣接する部分は通路Ｗ（図２を参照、図３には図示せず）を形成する。足場材１４は、作業員が補修等の各種作業を行う際の足場の役割も果たす。足場材１４が網状板材のように多数の孔を有することによって、潮が満ちて足場材１４が水没した際、足場材１４へ作用する外力が軽減され、脱落や損傷を防止することができる。   The scaffold material 14 is a net-like plate material such as expanded metal, for example. A portion of the scaffold 14 adjacent to the moving range of the carriage 15 along the rail 13 forms a passage W (see FIG. 2, not shown in FIG. 3). The scaffold material 14 also serves as a scaffold when the worker performs various operations such as repair. When the scaffolding member 14 has a large number of holes like a net-like plate member, when the scaffolding material 14 is submerged due to tide, the external force acting on the scaffolding member 14 is reduced, and dropping and damage can be prevented.

図５は、台車１５の構造の概略を示した図である。台車１５は、全体として板形状の本体１５１と、本体１５１の下面のレール１３に対向する位置に取り付けられたキャスター１５２と、本体１５１の下面に取り付けられたガイド部材１５３を備える。なお、図５等において、台車１５が安全上の理由で備える手摺り等の図示は省略している。   FIG. 5 is a diagram showing an outline of the structure of the carriage 15. The carriage 15 includes a plate-shaped main body 151 as a whole, a caster 152 attached at a position facing the rail 13 on the lower surface of the main body 151, and a guide member 153 attached to the lower surface of the main body 151. In addition, in FIG. 5 etc., illustration of the handrail etc. with which the trolley | bogie 15 is provided for safety reasons is abbreviate | omitted.

本体１５１は、例えば鋼材を格子状に組み上げたフレームの上に、例えばエキスパンドメタル等の網状板材を取り付けて構成された部材である。キャスター１５２はＹ方向を回転軸とする車輪を備え、レール１３の上を転がる車輪により、台車１５のＸ方向におけるスムースな移動を可能にする。   The main body 151 is a member configured by attaching a net-like plate material such as an expanded metal on a frame in which steel materials are assembled in a lattice shape, for example. The caster 152 includes a wheel having a rotation axis in the Y direction. The wheel rolling on the rail 13 enables the carriage 15 to move smoothly in the X direction.

ガイド部材１５３は、例えば、本体１５１から下方に延伸するシャフトと、シャフトを軸として自在に回転するローラを備える。ガイド部材１５３が備えるローラは、足場材１４により形成される通路Ｗとレール１３を挟む位置に配置され、レール１３の側面に接して回転する。ガイド部材１５３は、台車１５のＹ方向における位置決めを行い、台車１５のレール１３の上における移動方向を案内し、台車１５のレール１３からの脱落を防止する。図５に示すように、ガイド部材１５３は通路Ｗより台車１５の本体１５１側に配置されており、通路側に突出することがない。そのため、通路Ｗの幅が広く確保される。   The guide member 153 includes, for example, a shaft extending downward from the main body 151 and a roller that freely rotates around the shaft. The roller provided in the guide member 153 is disposed at a position sandwiching the passage W formed by the scaffold member 14 and the rail 13 and rotates in contact with the side surface of the rail 13. The guide member 153 positions the carriage 15 in the Y direction, guides the movement direction of the carriage 15 on the rail 13, and prevents the carriage 15 from falling off the rail 13. As shown in FIG. 5, the guide member 153 is disposed on the main body 151 side of the carriage 15 from the passage W, and does not protrude toward the passage side. Therefore, a wide width of the passage W is ensured.

図５に示されるように、台車１５は、Ｙ方向において隣接する２つの杭頭７１１のうち、一方の杭頭７１１（例えば、図５の左側の杭頭７１１）に取り付けられた支持部材１２の上に配置されたレール１３と、他方の杭頭７１１（例えば、図５の右側の杭頭７１１）に取り付けられた支持部材１２の上に配置されたレール１３とに掛け渡されるように配置される。従って、作業員は、一方の杭頭７１１の周囲の足場材１４により形成される通路Ｗ（例えば、図５の左側の通路Ｗ）と、他方の杭頭７１１の周囲の足場材１４により形成される通路Ｗ（例えば、図５の右側の通路Ｗ）との間を、それらの間に掛け渡された台車１５を介して往来することができる。   As shown in FIG. 5, the carriage 15 includes the support member 12 attached to one of the two pile heads 711 adjacent in the Y direction (for example, the left pile head 711 in FIG. 5). It arrange | positions so that it may span over the rail 13 arrange | positioned on the support member 12 attached to the rail 13 arrange | positioned on the other and the other pile head 711 (for example, the pile head 711 of the right side of FIG. 5). The Accordingly, the worker is formed by the passage W (for example, the left passage W in FIG. 5) formed by the scaffold 14 around the one pile head 711 and the scaffold 14 around the other pile head 711. It is possible to come and go to and from a passage W (for example, the passage W on the right side of FIG. 5) via a carriage 15 spanned between them.

図３に示すように、ステージ１６は、長手方向がＺ方向となるように床版７２の側面に取り付けられた長尺部材である鉛直部材１６１と、鉛直部材１６１の下端部からＸ方向に延伸するように鉛直部材１６１に取り付けられた長尺部材である横部材１６２と、一方の端部が鉛直部材１６１の上端部付近に取り付けられ、他方の端部が横部材１６２の一方の端部（鉛直部材１６１の下端部側ではない端部）付近に取り付けられた長尺部材である斜部材１６３と、横部材１６２の上に配置された足場材１６４を備える。   As shown in FIG. 3, the stage 16 extends in the X direction from the vertical member 161 that is a long member attached to the side surface of the floor slab 72 so that the longitudinal direction is the Z direction, and the lower end of the vertical member 161. The horizontal member 162 is a long member attached to the vertical member 161, and one end is attached in the vicinity of the upper end of the vertical member 161, and the other end is one end of the horizontal member 162 ( An oblique member 163 which is a long member attached in the vicinity of an end portion (not the lower end portion side of the vertical member 161) and a scaffold member 164 disposed on the lateral member 162 are provided.

鉛直部材１６１、横部材１６２及び斜部材１６３は、例えば溝形鋼であり、互いに溶接等により組み上げられ、レール１３及び足場材１６４を支持するフレームを構成する。足場材１６４は、例えばエキスパンドメタル等の網状板材であり、最も沖側の横部材１６２と最も岸側の横部材１６２の間の領域を概ね全て覆う。従って、作業員はステージ１６においては、台車１５を介さず足場材１６４の上を通行することができる。   The vertical member 161, the transverse member 162, and the oblique member 163 are, for example, channel steel, and are assembled by welding or the like to form a frame that supports the rail 13 and the scaffold member 164. The scaffold material 164 is a net-like plate material such as expanded metal, for example, and covers almost the entire region between the most offshore side transverse member 162 and the most shore side transverse member 162. Therefore, the worker can pass on the scaffolding material 164 on the stage 16 without passing through the carriage 15.

レール１３は、床版７２の下方空間Ｓ1からステージ１６側に突出している。レール１３のうち、ステージ１６側に突出している部分はステージ１６により支持されている。 The rail 13 protrudes from the lower space S 1 of the floor slab 72 toward the stage 16. A portion of the rail 13 that protrudes toward the stage 16 is supported by the stage 16.

上述した構成の移動式足場１は、レール１３に沿って、台車１５の移動範囲に隣接する位置に、足場材１４により通路Ｗが形成される。従って、作業員は通路Ｗ上を移動しながら、資材、機材等を載せた台車１５を押し進めることができる。図６は、通路上の作業員Ｐが資材Ｍの載せられた台車１５を押し進める状況を模式的に示した図である。台車１５はレール１３の上を転がる車輪を有するキャスター１５２を備えるため、重量が大きい資材、機材等が台車１５の上に載っていても、作業員はそれらの資材、機材等をレール１３に沿った方向に容易に移動することができる。   In the mobile scaffold 1 configured as described above, a passage W is formed by the scaffold material 14 at a position adjacent to the moving range of the carriage 15 along the rail 13. Accordingly, the worker can push forward the carriage 15 carrying materials, equipment, etc. while moving on the passage W. FIG. 6 is a diagram schematically showing a situation where the worker P on the passage pushes the carriage 15 on which the material M is placed. Since the carriage 15 includes a caster 152 having wheels that roll on the rail 13, even if heavy materials, equipment, and the like are placed on the carriage 15, the worker places the materials, equipment, etc. along the rail 13. Can be easily moved in any direction.

また、上述した構成の移動式足場１が備えるレール１３は、床版７２の下方空間Ｓ1から床版７２が上方にない空間Ｓ2（ステージ１６側の空間Ｓ2）へと延伸しているため、台車１５はレール１３の上を移動して、床版７２の下方空間Ｓ1とステージ１６側の空間Ｓ2との間を往来可能である。従って、作業員はステージ１６側の空間Ｓ2へ台車１５を移動し、台車１５の上に資材、機材等をクレーン等により吊り下ろした後、資材、機材等が載せられた台車１５を床版７２の下方空間Ｓ1へと移動することにより、床版７２の下方空間Ｓ1に対する資材、機材等の搬入を容易に行うことができる。 Further, the rail 13 provided in the mobile scaffold 1 having the above-described configuration extends from the lower space S 1 of the floor slab 72 to the space S 2 where the floor slab 72 is not above (the space S 2 on the stage 16 side). Therefore, the carriage 15 can move on the rail 13 and can travel between the lower space S 1 of the floor slab 72 and the space S 2 on the stage 16 side. Accordingly, the worker moves the carriage 15 to the space S 2 on the stage 16 side, suspends materials, equipment, etc. on the carriage 15 with a crane or the like, and then moves the carriage 15, on which the materials, equipment, etc. are placed, to the floor slab. by moving downwards the space S 1 72, Material for lower space S 1 of the floor plate 72, it is possible to easily carry equipment like.

また、作業員は、床版７２の下方空間Ｓ1において生じた廃棄材や余剰の資材、使用済みの機材等が載せられた台車１５を、ステージ１６側の空間Ｓ2へと移動した後、廃棄材等をクレーン等により吊り上げることにより、廃棄材等の撤去を容易に行うことができる。図７は、ステージ１６側の空間Ｓ2において、資材Ｍが台車１５の上に吊り下ろされる状況を模式的に示した図である。 In addition, the worker moves the carriage 15 on which waste materials, surplus materials, used equipment, and the like generated in the lower space S 1 of the floor slab 72 are moved to the space S 2 on the stage 16 side, By lifting the waste material or the like with a crane or the like, it is possible to easily remove the waste material or the like. FIG. 7 is a diagram schematically showing a situation where the material M is suspended on the carriage 15 in the space S 2 on the stage 16 side.

The above-described embodiment is a specific example of the present invention and may be variously modified. Examples of these modifications are shown below.

（１）本発明に係る移動式足場が設置される対象の構造物は桟橋に限られない。例えば、水上又は陸上の橋梁など、床版を備え、床版の下方に空間を有する構造物であれば、いずれの構造物であっても本発明に係る移動式足場の設置対象となり得る。 (1) The target structure on which the mobile scaffold according to the present invention is installed is not limited to a pier. For example, any structure having a floor slab, such as a water or land bridge, and having a space below the floor slab, can be a target for installation of the mobile scaffold according to the present invention.

（２）上述した移動式足場１が備えるレール１３と足場材１４は、ともに支持部材１２により支持される。これに代えて、レール１３と足場材１４が異なる支持部材により支持されてもよい。ただし、レール１３と足場材１４が共通の支持部材により支持される場合、それらが個別の支持部材により支持される場合と比較し、必要な支持部材の数が少なくなる。 (2) Both the rail 13 and the scaffold member 14 included in the above-described mobile scaffold 1 are supported by the support member 12. Instead, the rail 13 and the scaffold member 14 may be supported by different support members. However, when the rail 13 and the scaffold member 14 are supported by a common support member, the number of necessary support members is reduced as compared with the case where they are supported by individual support members.

（３）上述した移動式足場１が備えるブラケット１１は杭頭７１１に取り付けられているが、ブラケットの取り付け位置は杭頭に限られない。例えば、ブラケットが床版又は梁に取り付けられてもよい。また、ブラケットに代えて、例えば床版又は梁から吊り下げられるチェーン等により支持部材１２が支持されてもよい。 (3) Although bracket 11 with which mobile scaffold 1 mentioned above is attached to pile head 711, the attachment position of a bracket is not restricted to a pile head. For example, the bracket may be attached to a floor slab or a beam. Further, instead of the bracket, the support member 12 may be supported by, for example, a floor slab or a chain suspended from a beam.

（４）上述した移動式足場１が備えるレール１３は、開口面が下となる姿勢の溝形鋼に限定されず、開口面が上となる姿勢の溝形鋼でもよい。この溝形鋼は、台車１５の移動方向を案内するガイド部材を兼ねてもよい。 (4) The rail 13 provided in the above-described mobile scaffold 1 is not limited to the grooved steel in the posture in which the opening surface is downward, and may be grooved steel in the posture in which the opening surface is upward. This channel steel may also serve as a guide member for guiding the moving direction of the carriage 15.

（５）また、前記レール１３（変形例（４）においてガイド部材を兼ねる場合を含む）を構成する部材として、山形鋼、Ｈ形鋼、Ｉ形鋼、平鋼等の各種鋼材のいずれかが単独で使用されてもよいし、これらの鋼材の２以上が組み合わせて使用されてもよい。 (5) In addition, as a member constituting the rail 13 (including a case where it also serves as a guide member in the modified example (4)), any of various steel materials such as an angle steel, an H-shaped steel, an I-shaped steel, and a flat steel is used. They may be used alone, or two or more of these steel materials may be used in combination.

（６）移動式足場１が、同一のレール１３の上を移動する複数の台車１５を備えてもよい。この場合、移動式足場１が、複数の台車１５のうち隣接する２つを連結する連結部材を備えてもよい。図８は、複数の台車１５のうち、隣接する２つの台車１５−１及び台車１５−２が連結部材１７により連結された状態を模式的に示した図である。図８に例示の連結部材１７は、例えば「コ」の字形状の部材であり、２つの台車１５の各々の上面を形成する網状部材の孔に連結部材１７の２つの先端部が各々差し込まれることにより、２つの台車１５の連結が行われる。作業員は、連結部材１７を差し込む作業により２つの台車１５を容易に連結することができる。また、作業員は、連結部材１７を抜き取る作業により２つの台車１５の連結を容易に解放することができる。 (6) The mobile scaffold 1 may include a plurality of carriages 15 that move on the same rail 13. In this case, the mobile scaffold 1 may include a connecting member that connects two adjacent ones of the plurality of carriages 15. FIG. 8 is a diagram schematically showing a state in which two adjacent carts 15-1 and 15-2 are connected by the connecting member 17 among the plurality of carts 15. The connecting member 17 illustrated in FIG. 8 is, for example, a “U” -shaped member, and two distal ends of the connecting member 17 are inserted into holes of a mesh member that forms the upper surface of each of the two carriages 15. Thus, the two carts 15 are connected. An operator can easily connect the two carriages 15 by inserting the connecting member 17. Further, the worker can easily release the connection of the two carriages 15 by the operation of removing the connection member 17.

（７）上述した実施形態において説明した移動式足場１の構成部の素材、形状、数量、配置等は一例であって、様々に変更されてもよい。例えば、上述した移動式足場１が備える足場材１４及び足場材１６４は網状部材であるものとしたが、移動式足場１が水流や風の影響を強く受けない場所に設置される場合、足場材１４及び足場材１６４は多くの孔を持たない板状部材であってもよい。また、強度の確保、安全性の確保等の理由により、移動式足場１が、上述した実施形態において説明した部材以外の部材を備えてもよい。 (7) The material, shape, quantity, arrangement, and the like of the constituent parts of the mobile scaffold 1 described in the above-described embodiment are examples, and may be variously changed. For example, the scaffold 14 and the scaffold 164 included in the above-described mobile scaffold 1 are assumed to be net members, but when the mobile scaffold 1 is installed in a place that is not strongly affected by water flow or wind, the scaffold 14 and the scaffold material 164 may be plate-like members having no many holes. Further, for reasons such as ensuring strength and ensuring safety, the mobile scaffold 1 may include members other than the members described in the above-described embodiments.
