Description

この発明は、例えば、室内作業の足場として用いる組立て式の移動足場に関する。 The present invention relates to an assembly type moving scaffold used as a scaffold for indoor work, for example.

作業床高さが２ｍを超える室内足場として、一般的にはローリングタワーやパンタグラフ式室内移動足場が使用されている。 In general, a rolling tower or a pantograph type indoor moving scaffold is used as an indoor scaffold with a work floor height exceeding 2 m.

前者のローリングタワーは、両側の支柱を横架材で結合した枠体を対向配置し、対向する枠体を筋交いと横架材で結合して枠状体を組み、この枠状体を上方へ必要な高さだけ継ぎ足していくと共に、所定高さ位置にある横架材間に作業床を架設してステージとし、枠体の横桟を梯子として作業床への昇り降りを行なう構造になっている（例えば、特許文献１参照）。 In the former rolling tower, a frame body in which struts on both sides are coupled with a horizontal member is arranged oppositely, the opposing frame members are straddled and coupled with a horizontal member, and the frame member is assembled. As long as the required height is added, the work floor is constructed between the horizontal members at the specified height and used as a stage, and the horizontal rail of the frame is used as a ladder to ascend and descend the work floor. (For example, refer to Patent Document 1).

また、後者のパンタグラフ式室内移動足場は、起立状態で両側に対向させた支持枠を伸縮自在となるパンタグラフ機構で結合し、両支持枠の接近による折り畳みと離反を可能とし、離反させた両支持枠間の上端に手すり枠を取付けると共に、作業床を架設して組立てられ、梯子となる支持枠を利用して作業床への昇り降りを行なうようになっている（例えば、特許文献２参照）。
特開平８−２８０３０号公報特開平１０−２３１６１７号公報 In addition, the latter pantograph-type indoor movement scaffold is constructed by connecting the support frames facing both sides in a standing state with a pantograph mechanism that can be expanded and contracted to enable folding and separation due to the approach of both support frames. A handrail frame is attached to the upper end between the frames, and a work floor is installed and assembled, and the work frame ascends and descends using a support frame serving as a ladder (see, for example, Patent Document 2). .

ところで、従来のローリングタワーは、必要とする高さのステージを組立てることができるという利点はあるが、各構成部材が分離独立しているため、部品点数が多く組立て及び解体に手間と時間がかかるだけでなく、全体の重量が重く、コスト的に高く付くだけでなく、組立て解体に専門の知識が要求されるという問題がある。 By the way, the conventional rolling tower has an advantage that a stage having a required height can be assembled. However, since each component is separated and independent, the number of parts is large and it takes time and labor to assemble and disassemble. In addition to the heavy weight and high cost, there is a problem that specialized knowledge is required for assembly and disassembly.

また、パンタグラフ式室内移動足場は、折り畳むことで嵩低くなり格納や輸送に便利で、組立てや解体が容易に行なえるが、ステージの高さは一定化した構造となり、作業条件の変化に対応することが困難となり、使い勝手が悪いという問題がある。 In addition, the pantograph-type indoor movement scaffolding can be folded to make it less bulky and convenient for storage and transportation, and can be easily assembled and disassembled, but the stage height is a constant structure, which responds to changes in working conditions. There is a problem that it is difficult to use and is not easy to use.

更に、従来のローリングタワーやパンタグラフ式室内移動足場は、作業床への昇り降りが、枠体の横桟や支持枠を梯子として利用するため、昇り降り時は正面以外に保護するものが何もなく、昇り降りに恐怖を感じることになり、作業床が高い場合の墜落による事故の危険性もある。 In addition, conventional rolling towers and pantograph-type indoor movement scaffolds use the horizontal rails and support frames of the frame as ladders for ascending and descending to the work floor. However, there is a danger of accidents due to a crash when the work floor is high.

そこで、この発明が解決しようとする課題は、極力部品点数を少なくして所望高さの作業ステージを構築することができ、しかも、全体が軽量コンパクトでコスト的にも安価となり、専門知識を必要とすることなく誰でも簡単に組立と解体が行なえる移動足場を提供することである。 Therefore, the problem to be solved by the present invention is that a work stage having a desired height can be constructed by reducing the number of parts as much as possible, and the whole is lightweight and compact, and is inexpensive in terms of cost, requiring specialized knowledge. It is to provide a mobile scaffold that anyone can easily assemble and dismantle.

上記のような課題を解決するため、この発明は、横桟材を結合して矩形枠状に組立てられ、四隅の位置に縦柱を立設すると共に下部四隅の位置にキャスターを設けたベース部材と、前記ベース部材の縦柱上に接続できると同時に、自身も上方に継足し接続することができる二本の縦柱を、前記ベース部材の対角位置にある縦柱と等しい間隔となるよう上下の横桟で結合して形成した枠体を二つ用い、この二つの枠体を上下の横桟の部分で互いに嵌め合わせてこの横桟の交差する中央部分を枢止結合し、両枠体の縦柱が重なる折り畳みから、ベース部材の対角位置にある二組の縦柱の対角線がなす角度に一致するクロス状態に開くことができるように形成され、前記ベース部材上に継ぎ足していくことができる中間枠部材と、クロス形状に開いた中間枠部材の両側に位置する縦柱上に起立するよう取り付け、中間枠部材上の両側に対向するよう配置する枠体に、この枠体に重なる起立状態から中間枠部材の上部に水平伏倒する起伏動自在の作業床を設けた作業床付手すり枠と、対向する作業床付手すり枠間に起立するよう取付ける手すり枠とからなり、前記中間枠部材が、一方枠体の上下横桟間に、この一方枠体に平行する格納状態から回動自在に取付けられ、ベース部材をクロス形状に開いた状態で他方枠体と結合することができる梯子部材を備えている構成を採用したものである。 In order to solve the above-mentioned problems, the present invention is a base member that is assembled in a rectangular frame shape by combining horizontal rail members, and vertical columns are erected at the four corner positions and casters are provided at the lower four corner positions. The two vertical columns that can be connected to and connected to the vertical column of the base member at the same time as the vertical columns at the diagonal positions of the base member are equal to each other. Two frames formed by joining the upper and lower horizontal rails are used, the two frames are fitted to each other at the upper and lower horizontal rails, and the central portion where the horizontal rails intersect is pivotally connected. It is formed so that it can be opened in a cross state that matches the angle formed by the diagonal lines of the two vertical columns at the diagonal position of the base member from the folding where the vertical columns of the body overlap, and is added to the base member Intermediate frame member that can be opened in a cross shape Installed to stand on the vertical pillars located on both sides of the intermediate frame member, and horizontally lying on the upper part of the intermediate frame member from the standing state that overlaps this frame body to the frame body arranged to face both sides on the intermediate frame member A handrail frame with a work floor provided with a work floor that can freely move up and down, and a handrail frame that is attached to stand between the handrail frames with the work floor facing each other, and the intermediate frame member is between the upper and lower horizontal rails of one frame body In addition, the structure is provided with a ladder member that is rotatably attached from the retracted state parallel to the one frame body and that can be coupled to the other frame body with the base member opened in a cross shape. is there.

ここで、上記ベース部材は、四隅に配置した縦パイプを上部と下部の横桟材で結合し、前後方向の奥行きよりも横幅が少し広い矩形枠体に組立てられ、前記縦パイプを上下に貫通するジャッキ軸の下端にキャスターを取付けると共に、このキャスターよりも上部の位置に縦パイプの下端を受ける回転ねじ式のジャッキ部材を螺合し、ジャッキ部材の回動で高さの調整が可能になっていると共に、この各縦パイプには、アウトリガーが前後の方向に突出するよう固定され、横幅方向の両側で前後に位置する下位横桟材の間に内側横桟を架設し、この両内側横桟の両端部寄りの位置に縦柱を立設することにより、前記矩形枠体の内部で四隅の位置に合計四本の縦柱が配置されている。 Here, the base member is formed by connecting vertical pipes arranged at the four corners with upper and lower horizontal crosspieces and assembled into a rectangular frame whose width is slightly wider than the depth in the front-rear direction, and penetrates the vertical pipe vertically. A caster is attached to the lower end of the jack shaft, and a rotating screw type jack member that receives the lower end of the vertical pipe is screwed at a position above the caster, and the height can be adjusted by rotating the jack member. In addition, each vertical pipe is fixed so that the outrigger protrudes in the front-rear direction, and an inner horizontal beam is installed between the lower horizontal beams located on the both sides in the width direction. A total of four vertical pillars are arranged at four corners inside the rectangular frame by standing upright pillars at positions close to both ends of the crosspiece.

上記中間枠部材における枠体は、縦柱を結合する上下横桟間の両端部寄りの位置に縦桟を設け、一方枠体の両縦桟にそれぞれ梯子部材が回動自在に取り付けられ、中間枠部材をクロス状態に開いた状態で梯子部材を回動させ、先端の係止部材を他方枠体の対応する縦桟に対して係止すれば、中間枠部材の開いた状態が保持され、梯子部材での昇り降りができることになる。 The frame in the intermediate frame member is provided with vertical bars at positions near both ends between the upper and lower horizontal bars that join the vertical columns, and a ladder member is rotatably attached to each of the vertical bars of the frame body. If the ladder member is rotated in a state where the frame member is opened in a cross state, and the locking member at the tip is locked to the corresponding vertical beam of the other frame body, the open state of the intermediate frame member is maintained, You can go up and down on the ladder member.

この中間枠部材は、例えば高さ寸法が５００ｍｍと１０００ｍｍの二種類を用意し、これを使い分けることにより、構築する移動足場の高さ設定を細かな範囲で行なえるようにすることができる。 As the intermediate frame member, for example, two types of height dimensions of 500 mm and 1000 mm are prepared, and by using them properly, the height of the moving scaffold to be constructed can be set within a fine range.

上記作業床付手すり枠は、枠体が下向きコ字状に形成され、その両側下端を、クロス形状に開いた中間枠部材の両側に位置する縦柱上に起立するよう接続することによって取り付けるようになっていると共に、作業床は枠体の両側下端部に、この枠体に重なる起立格納状態から水平に伏倒する起伏動自在になっている。 The above-mentioned handrail frame with work floor is attached by connecting the frame body so as to stand upright on the vertical pillars located on both sides of the intermediate frame member opened in a cross shape, with the frame body formed in a downward U-shape. In addition, the work floor can be freely raised and lowered at the lower end portions on both sides of the frame body so as to be horizontally laid down from the standing storage state overlapping the frame body.

上記手すり枠は、下向きのコ字状枠体が、両側に対向状態で起立する作業床付手すり枠間に納まるように形成され、コ字状枠体の中間に手すり横桟と下部に腰板が設けられ、両側に対向状態で起立する作業床付手すり枠に、フックとホルダーを用いて利用側を固定するようになっている。 The above-mentioned handrail frame is formed so that the downward U-shaped frame is placed between the handrail frames with work floors standing upright on both sides, with the handrail horizontal rail in the middle of the U-shaped frame and the waist plate at the bottom The use side is fixed to a handrail frame with a work floor that is provided and stands upright on both sides using a hook and a holder.

また、ベース部材と中間枠部材、中間枠部材上に取付ける作業床付手すり枠と手すり枠の組合わせであるので、移動足場を構成する部品の種類と点数を極力少なくすることができ、コスト的にも廉価なものとなる。 Also, since it is a combination of a base member, an intermediate frame member, and a handrail frame with a work floor attached on the intermediate frame member and a handrail frame, the types and the number of parts constituting the moving scaffold can be reduced as much as possible. Even cheaper.

更に、中間枠部材の接続数を増減したり、高さの異なる中間枠部材を組み合わせ使用することで、所望高さの作業ステージを構築することができ、しかも、中間枠部材は扁平に折り畳めるので、使用しないときに全体を嵩低く積み重ねることが可能になり、格納や運搬時に有利となる。 Furthermore, by increasing or decreasing the number of intermediate frame members connected or using intermediate frame members with different heights, a work stage with a desired height can be constructed, and the intermediate frame members can be folded flat. When not in use, it is possible to stack the whole with a low volume, which is advantageous during storage and transportation.

更にまた、中間枠部材は、二つの枠体を上下の横桟の部分で互いに嵌め合わせてこの横桟の交差する中央部分を枢止結合してクロス状態に開くことができるように形成し、前記一方枠体の上下横桟間に、この一方枠体に平行する格納状態から回動自在に取付けられ、中間枠部材をクロス形状に開いた状態で他方枠体と結合する梯子部材を設けたので、作業ステージへの作業員の昇り降りが梯子部材を利用して行なえ、梯子部材はクロス状態に開いた枠体間に設けられていることで、梯子面の両側が枠体の一部で囲まれることになり、梯子部材を昇降する際の恐怖感を少なくすることができ、梯子部材を昇り降りする場合の安全性を向上させることができる。 Furthermore, the intermediate frame member is formed so that the two frame bodies can be fitted to each other at the upper and lower horizontal beam portions, and the central portion where the horizontal beam intersects can be pivotally coupled to open in a cross state. A ladder member is provided between the upper and lower horizontal rails of the one frame body so as to be freely rotatable from a retracted state parallel to the one frame body and coupled to the other frame body with the intermediate frame member opened in a cross shape. Therefore, the worker can be moved up and down to the work stage using the ladder member, and the ladder member is provided between the frame bodies opened in a cross state, so that both sides of the ladder surface are part of the frame body. It will be enclosed, the fear at the time of raising / lowering a ladder member can be decreased, and the safety | security when going up and down a ladder member can be improved.

A moving caster 10 is attached to the lower end of a jack shaft 9 that vertically passes through the vertical pipes 6 at the four corners, and a rotary screw type jack member 11 that receives the lower end of the vertical pipe 6 at a position above the caster 10. And the height can be adjusted by rotating the jack member 11. Here, in the plan view of FIG. 3B, the front-rear direction in the moving scaffold 1 refers to the direction in which the width of the base member 2 is narrow, and the lateral direction refers to the direction in which the width is wide.

上記各縦パイプ６には、前後の方向に突出するよう固定したアーム１２の先端に、ハンドル１３の操作によって接地部材１４を上下に位置調整可能となるよう取付けたアウトリガー１５が突設され、ベース部材２を床面に固定化することができるようになっている。 Each vertical pipe 6 is provided with an outrigger 15 projecting from the tip of an arm 12 fixed so as to protrude in the front-rear direction so that the grounding member 14 can be adjusted in the vertical direction by operating the handle 13. The member 2 can be fixed to the floor surface.

上記ベース部材２の内部には、横幅方向の両側で前後の位置に、合計四本の角縦柱１６が上下端を前後に位置する上横桟材７と下横桟材８に固定することによって配置され、前後に位置する角縦柱１６間に横杆１７が水平に架設されている。 Inside the base member 2, a total of four square vertical columns 16 are fixed to the upper horizontal beam member 7 and the lower horizontal beam member 8 whose upper and lower ends are positioned in the front-rear direction on both sides in the width direction. A horizontal bar 17 is installed horizontally between the square vertical columns 16 located at the front and rear.

図３（ａ）のように、上記横杆１７は、角縦柱１６間に納まる長さを有し、その両端に、角縦柱１６に対して外嵌するコ字状金具１８を設け、角縦柱１６に複数の取付け孔１９を上下に所定の間隔で設け、コ字状金具１８をピン２０の抜き差しで所望の取付け孔１９に固定することにより、ベース部材２の内部で両側に前後方向に沿う横杆１７を架設するようになっている。 As shown in FIG. 3 (a), the horizontal bar 17 has a length that fits between the rectangular vertical columns 16, and is provided with U-shaped metal fittings 18 that are externally fitted to the rectangular vertical columns 16, A plurality of mounting holes 19 are provided on the rectangular vertical column 16 at predetermined intervals in the vertical direction, and the U-shaped bracket 18 is fixed to the desired mounting hole 19 by inserting / removing the pins 20, so A horizontal rod 17 is erected along the direction.

この横杆１７は、取付け孔１９を選ぶことで、架設時の高さ位置を取付け孔１９の間隔で上下に調整できると共に、横杆１７の上面で前後両端部寄りの位置に、中間枠部材３を接続するための短い高さ寸法のパイプ製縦柱２１が立設されている。 By selecting the mounting hole 19, this horizontal bar 17 can adjust the height position when erected vertically by the interval of the mounting hole 19, and at the upper surface of the horizontal bar 17, the intermediate frame member is positioned closer to the front and rear ends. A vertical column 21 made of pipe with a short height for connecting 3 is erected.

上記のように、ベース部材２は、その内部四隅に中間枠部材３を接続するための縦柱２１が合計四本配置され、例えば、この縦柱２１の前後間隔は７００ｍｍに、横方向の間隔は１４００ｍｍに設定され、横杆１７の架設高さを取付け孔１９の間隔で選ぶことと、アウトリガー１５による上下持ち上げ高さを調整することにより、縦柱２１の配置高さを調整することができる。 As described above, the base member 2 has a total of four vertical columns 21 for connecting the intermediate frame member 3 at the four inner corners thereof. For example, the vertical column 21 has a longitudinal interval of 700 mm and a horizontal interval. Is set to 1400 mm, and the arrangement height of the vertical column 21 can be adjusted by selecting the installation height of the horizontal rod 17 according to the interval between the mounting holes 19 and adjusting the vertical lifting height by the outrigger 15. .

上記中間枠部材３は、図１乃至図７のように、上記ベース部材２の縦柱２１上に接続できると同時に、自身も上方に継足し接続することができる二本の縦柱２２を、前記ベース部材２の対角位置にある縦柱２１と等しい間隔となるよう上下のパイプ製横桟２３と２４で結合して枠体２５を組み、この枠体２５を二つ用い、二つの枠体２５、２５を上下の横桟２３、２４の部分で互いに嵌め合わせてこの横桟２３、２４の交差する中央部分をピン２６で枢止結合し、図７（ｂ）のように、両枠体２５、２５の縦柱２２が重なる折り畳みから、図７（ａ）のように、ベース部材２の対角位置にある二組の縦柱２１の対角線がなす角度に一致するクロス状態に開くことができるように形成されている。 As shown in FIGS. 1 to 7, the intermediate frame member 3 can be connected to the vertical column 21 of the base member 2 and at the same time has two vertical columns 22 that can be connected and connected upward. The frame member 25 is assembled by connecting the upper and lower pipe crosspieces 23 and 24 so as to have the same interval as the vertical column 21 at the diagonal position of the base member 2, and two frames 25 are used to form two frames. The bodies 25, 25 are fitted to each other at the upper and lower horizontal bars 23, 24, and the central portion where the horizontal bars 23, 24 intersect is pivotally connected by a pin 26. As shown in FIG. From the folding where the vertical pillars 22 of the bodies 25 and 25 are overlapped, as shown in FIG. 7A, the body 25 is opened in a cross state that matches the angle formed by the diagonal lines of the two vertical pillars 21 at the diagonal positions of the base member 2. It is formed to be able to.

上記中間枠部材３における枠体２５、２５は、縦柱２２を結合する上下横桟２３、２４間の両端部寄りの位置にパイプ製の縦桟２７、２７を設け、一方枠体２５の両縦桟２７、２７にはそれぞれ梯子部材２８が、この一方枠体２５に重なる収納状態から他方枠体２５に向けて回動させることができるように取り付けられている。 The frame bodies 25, 25 in the intermediate frame member 3 are provided with pipe-made vertical bars 27, 27 at positions near both ends between the upper and lower horizontal bars 23, 24 that join the vertical columns 22. A ladder member 28 is attached to each of the vertical bars 27 and 27 so that the ladder member 28 can be rotated toward the other frame body 25 from the storage state overlapping the one frame body 25.

この梯子部材２８は、図５のように、両側縦パイプ２８ａ間に上下複数段の踏桟２８ｂを設けて枠状梯子に形成され、一方側縁の上下端を上記縦桟２７の上下端に一対のヒンジ金具２９で平面的に回動するよう枢止され、中間枠部材３の両枠体２５をクロス状態に開いた状態で梯子部材２８を回動させ、先端の係止部材３０を他方枠体２５の対応する縦桟２７に対して係止すれば、中間枠部材３の開いた状態が保持され、梯子部材２８に対する昇り降りができることになる。 As shown in FIG. 5, the ladder member 28 is formed in a frame-like ladder by providing a plurality of upper and lower step bars 28 b between the vertical pipes 28 a on both sides, and the upper and lower ends of one side edge are the upper and lower ends of the vertical bars 27. The ladder member 28 is pivoted with the pair of hinge brackets 29 pivoted in a plane and the frame members 25 of the intermediate frame member 3 are opened in a cross state, and the locking member 30 at the tip is moved to the other side. When the frame 25 is locked to the corresponding vertical beam 27, the intermediate frame member 3 is kept open, and the ladder member 28 can be moved up and down.

上記中間枠部材３は、例えば縦柱２２の高さ寸法が５００ｍｍと１０００ｍｍの二種類を用意し、これを使い分けたり組合わせることにより、構築する移動足場１の高さ設定を細かな範囲で行なえるようにすることができ、枠体２５と２５のクロス構造を採用することによって中間枠部材３は軽量化と強度のアップが図れることになる。 As the intermediate frame member 3, for example, two types of heights of the vertical column 22 of 500 mm and 1000 mm are prepared, and the height of the mobile scaffold 1 to be constructed can be set in a fine range by using or combining them. By adopting the cross structure of the frame bodies 25 and 25, the intermediate frame member 3 can be reduced in weight and strength.

The intermediate frame member 3 may be removed from the vertical column 21 of the base member 2 and the ladder member 28 and both frame bodies 25 and 25 may be folded in the reverse order as described above, and folded after disassembly. The intermediate frame member 3, the handrail frame 4 with the work floor, and the handrail frame 5 are placed on the base member 2, and the base member 2 is used as a transport carriage.

このように、移動足場１の組立ては、ベース部材２の縦柱２１に対してクロス状態に開いた中間枠部材３を接続し、中間枠部材３の上に作業床付手すり枠４と手すり枠５を立設するだけでよく、また、解体は、組立ての逆手順で行なえるので、組立てや解体が単純に上下にパイプを接続したり分離させるだけでよく、専門知識を必要とすることなく誰でも簡単に組立と解体が行なえる。 Thus, the assembly of the movable scaffold 1 is performed by connecting the intermediate frame member 3 opened in a cross state to the vertical column 21 of the base member 2, and the handrail frame 4 with the work floor and the handrail frame on the intermediate frame member 3. 5 can be installed upright, and disassembly can be done in the reverse order of assembly, so assembly and disassembly can be done simply by connecting and disconnecting pipes up and down, without requiring specialized knowledge. Anyone can easily assemble and disassemble.

この発明の移動足場１は、それ単体で作業ステージとして使用できるが、この移動足場１を基本ステージとして複数用い、作業条件に合わせたレイアウトの発展形作業ステージを構築することができる。 The mobile scaffold 1 according to the present invention can be used alone as a work stage, but a plurality of the mobile scaffolds 1 can be used as basic stages to construct an extended work stage having a layout according to work conditions.

図１３は、二台の移動足場１を長さ方向に連結して作業ステージを形成した例であり、隣接する移動足場１のステージにおける接続端部は、作業床付手すり枠４の使用を省き、これに代えて通行の邪魔にならない中間用柱部材５１を、中間枠部材３における前後縦柱２２の上に立設し、作業床の欠けた部分に別途用意した単独作業床５２を敷設するようにする。 FIG. 13 is an example in which two moving scaffolds 1 are connected in the length direction to form a work stage. The connection end portion of the stage of the adjacent mobile scaffold 1 omits the use of the handrail frame 4 with a work floor. Instead of this, an intermediate column member 51 that does not interfere with traffic is erected on the front and rear vertical columns 22 in the intermediate frame member 3, and a separately prepared single work floor 52 is laid on the lacked portion of the work floor. Like that.

上記中間用柱部材５１は、図１５（ａ）のように、その下端に作業床付手すり枠４と同様の鍔と係止金具が、また、上端と下部に手すり枠を結合するためのホルダーが設けられた金属製の縦パイプ５３を二本用い、両縦パイプ５３の下部の位置を腰板５４により、クロス状に開いた中間枠部材３の前後の縦柱２２に等しい間隔で結合して形成され、中間枠部材３上で作業床付手すり枠４を省いた部分に、この中間用柱部材５１を立設し、手すり枠５の端部をこの中間柱部材５１に結合する。 As shown in FIG. 15 (a), the intermediate column member 51 is provided with a hook and a locking bracket similar to those of the handrail frame 4 with a work floor at its lower end, and a holder for coupling the handrail frame to the upper end and lower portion. Two vertical pipes 53 made of metal are provided, and the positions of the lower parts of both vertical pipes 53 are joined by waist plates 54 at equal intervals to the longitudinal pillars 22 before and after the intermediate frame member 3 opened in a cross shape. This intermediate column member 51 is erected on the intermediate frame member 3 where the handrail frame 4 with work floor is omitted, and the end of the handrail frame 5 is coupled to the intermediate column member 51.

また、単独作業床５２は、図１６に示すように、縦横の鋼材で組んだ枠体５２ａの上面にラス金網等の床材５２ｂを張設し、前後手すり枠５と中間用柱部材５１で囲まれた作業床欠落部分に納まるよう、移動足場１の長さ方向の略半分の大きさに形成され、前後手すり枠５と中間用柱部材５１の腰板３５と５４に設けた突条３８で周辺を支持することによって敷設する。 Further, as shown in FIG. 16, the single work floor 52 has a floor material 52 b such as a lath wire mesh stretched on the upper surface of a frame body 52 a formed of vertical and horizontal steel materials, and is composed of front and rear handrail frames 5 and an intermediate column member 51. A protrusion 38 formed on the front and rear handrail frame 5 and the waist plates 35 and 54 of the intermediate column member 51, which is formed to be approximately half the length of the moving scaffold 1 so as to fit in the enclosed work floor missing portion. Lay by supporting the periphery.

このような移動足場１の接続において、隣接するベース部材２を結合するため、図３のように、横桟材７と８の上面にプレースピン５５を立設しておき、隣接するベース部材２をプレースピン５５に結合したプレース５６で連結するようにしている。 In such connection of the moving scaffold 1, in order to connect the adjacent base members 2, the place pins 55 are erected on the upper surfaces of the crosspieces 7 and 8, as shown in FIG.

図１４は、長さ方向を平行させた二台の移動足場１の間に、並列させた丁度二台の移動足場１分のスペースを設け、このスペースの部分に単独作業床５２を敷設することにより作業ステージとした例であり、増設作業スペースの形成には、梁部材５７と上記した手すり枠５及び単独作業床５２が用いられる。 FIG. 14 shows that two moving scaffolds 1 in parallel are provided between two movable scaffolds 1 whose lengths are parallel to each other, and a single work floor 52 is laid in this space. The beam member 57, the handrail frame 5 and the single work floor 52 are used for forming the additional work space.

上記梁部材５７は、図１５（ｂ）のように、中間用柱部材５１の腰板５４と同様、下縁に突条３８を備えた断面形状の帯板状に形成され、対向する作業床付手すり枠４の間に納まる長さを有し、その両端に作業床付手すり枠４のホルダー３７に係止するフック５８を設け、中間位置にフック５８を係止するホルダー５９が設けられている。 As shown in FIG. 15 (b), the beam member 57 is formed in the shape of a strip plate having a ridge 38 on the lower edge, similar to the waist plate 54 of the intermediate column member 51, and has an opposing work floor. A hook 58 that has a length that fits between the handrail frames 4 and that is engaged with the holder 37 of the handrail frame 4 with a work floor is provided at both ends thereof, and holders 59 that engage the hooks 58 are provided at intermediate positions. .

長さ方向を平行させた二台の移動足場１において、手すり枠５を省いた部分に、即ち、中間枠部材３の長さ方向に位置する縦柱２２の上に梁部材５７を架設し、両側に平行する梁部材５７間の中間に同じ梁部材５７を架設し、隣接する作業床付手すり枠４の間に手すり枠５を取付け、増設作業スペースとなる部分に単独作業床５２を敷設することによって作業ステージが構築できる。当然ながらこの場合も、隣接する移動足場１は、ベース部材２をプレース５６で互いに結合するようにする。 In the two moving scaffolds 1 whose length directions are parallel to each other, a beam member 57 is installed on a portion where the handrail frame 5 is omitted, that is, on the vertical column 22 positioned in the length direction of the intermediate frame member 3. The same beam member 57 is laid in the middle between the beam members 57 parallel to both sides, the handrail frame 5 is attached between the adjacent handrail frames 4 with work floors, and the single work floor 52 is laid in a portion that becomes an additional work space. A work stage can be constructed. Of course, also in this case, the adjacent moving scaffolds 1 connect the base members 2 to each other at a place 56.

なお、発展形作業ステージの構築は、図示例のレイアウトに限るものではなく、上記のような中間用柱部材５１、梁部材５７、単独作業床５２、プレース５６等を用いることで、所望する平面的な大きさと形状の作業ステージを構築できる。 The construction of the advanced work stage is not limited to the layout in the illustrated example, and a desired plane can be obtained by using the intermediate column member 51, the beam member 57, the single work floor 52, the place 56, and the like as described above. It is possible to construct a work stage with a specific size and shape.
