ところが、従来の吊り足場装置では、結合部材が、吊り材を取付け可能な筒状の吊り材ブラケットと、吊り材ブラケットの周囲に設けられて縦梁及び横梁を連結可能な孔を有するフランジとを備えて構成されているため、結合部材の横幅は縦梁の横幅よりも非常に広い。 However, in the conventional suspended scaffolding device, the connecting member consists of a tubular suspension bracket to which the suspension material can be attached, and a flange provided around the suspension material bracket and having a hole for connecting the vertical beam and the horizontal beam. As it is configured, the lateral width of the connecting members is much wider than the lateral width of the longitudinal beams.

そのため、縦梁の一端に結合部材を予め取付けて縦梁と結合部材を一体化すると、結合部材が横方向にかさばって、結合部材と一体化した縦梁の保管や運搬が難しくなるといった不具合があった。 Therefore, if a connecting member is attached to one end of the vertical beam in advance and the vertical beam and the connecting member are integrated, the connecting member becomes bulky in the horizontal direction, making it difficult to store and transport the vertical beam integrated with the connecting member. there were.

そこで、本発明は、縦梁に結合部材を一体化しても、縦梁の保管や運搬が容易となる吊り足場装置及び吊り足場装置の組立方法を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a suspended scaffolding device and a method for assembling a suspended scaffolding device that facilitates storage and transportation of the longitudinal beams even if the connecting members are integrated with the longitudinal beams.

上記の目的を達成させるため、本発明の吊り足場装置は、奥行方向に沿って直列に連結可能であって幅方向で平行に配置される複数の縦梁と、幅方向で隣り合う前記縦梁の一端同士の間に架け渡される横梁と、幅方向で隣り合う前記縦梁間に架け渡される足場板とを備え、前記縦梁は、梁本体と、前記梁本体の一端に設けられて前記縦梁を吊持する吊り材を取付け可能な吊り材ブラケットと、前記吊り材ブラケットの反梁本体側に設けられる第一連結部材と、前記梁本体の他端に設けられて奥行方向で隣り合う前記縦梁の前記第一連結部材に連結可能な第二連結部材とを有し、前記横梁の各端部は、幅方向で隣り合う前記縦梁の前記第一連結部材にそれぞれ連結されることを特徴とする。この構成によると、吊り材ブラケットと第一連結部材が縦梁の長手方向に沿って直列に配置されるので、吊り材ブラケットと第一連結部材とを有する結合部材の横幅を短くできる。 In order to achieve the above object, the suspended scaffolding device of the present invention provides a plurality of vertical beams that can be connected in series along the depth direction and are arranged in parallel in the width direction, and the vertical beams that are adjacent in the width direction. A horizontal beam bridged between one ends thereof and a scaffolding board bridged between the vertical beams adjacent in the width direction, the vertical beams comprising a beam body and one end of the beam body provided at one end of the vertical beam body a hanging material bracket to which a hanging material for suspending a beam can be attached; a first connecting member provided on the opposite side of the beam body of the hanging material bracket; and a second connecting member connectable to the first connecting member of the vertical beam, and each end of the horizontal beam is connected to the first connecting member of the longitudinal beams adjacent in the width direction. Characterized by According to this configuration, since the suspension material bracket and the first connecting member are arranged in series along the longitudinal direction of the vertical beam, the width of the connecting member having the suspension material bracket and the first connecting member can be reduced.

また、本発明の吊り足場装置は、奥行方向で隣り合う前記縦梁のうちで手前側の縦梁の前記第一連結部材に対して奥側の縦梁の前記第二連結部材を水平方向に回転自在に連結する回転連結装置と、前記奥側の縦梁が前記手前側の縦梁に対して直列に配置された状態で前記奥側の縦梁の前記第二連結部材を前記手前側の縦梁の前記第一連結部材に対して回転不能に固定する回り止め装置とを備えてもよい。この構成によると、吊り足場装置の組立時において、奥側の縦梁を吊り足場装置の幅方向に沿わせた状態で、手前側の縦梁に対して回転自在に連結できるので、2人の作業者で奥側の縦梁を保持しながら、奥側の縦梁を手前側の縦梁に連結する作業を行うことができる。よって、奥行方向で隣り合う縦梁同士の連結作業を安全に行うことができる。 Further, in the suspended scaffolding device of the present invention, among the longitudinal beams adjacent in the depth direction, the second connecting member of the longitudinal beam on the back side is horizontally arranged with respect to the first connecting member of the longitudinal beam on the front side. a rotary connecting device for rotatably connecting the second connecting member of the back vertical beam to the front vertical beam in a state in which the back vertical beam is arranged in series with the front vertical beam; A detent device may be provided for non-rotatably fixing the longitudinal beam to the first connecting member. According to this configuration, when assembling the suspended scaffolding device, the longitudinal beam on the far side can be rotatably connected to the longitudinal beam on the front side in a state of being aligned in the width direction of the suspended scaffolding device, so that two people can A worker can connect the back side vertical beam to the front side vertical beam while holding the back side vertical beam. Therefore, it is possible to safely perform the work of connecting the longitudinal beams adjacent to each other in the depth direction.

また、本発明の吊り足場装置では、前記第一連結部材は、前記吊り材ブラケットから反梁本体側に向けて延びる第一連結片を有し、前記第二連結部材は、前記梁本体の他端から前記梁本体の軸方向に沿って延びる第二連結片を有し、前記回転連結装置は、前記第一連結片と前記第二連結片にそれぞれ形成される固定孔と、前記第一連結片と前記第二連結片を上下に重ねた状態で上下に対向する前記固定孔に挿入される連結ピンとを有し、前記回り止め装置は、前記第一連結片と前記第二連結片にそれぞれ形成される回り止め孔と、前記第一連結片と前記第二連結片を上下に重ねた状態で上下に対向する前記回り止め孔に挿入される回転止めピンとを有してもよい。この構成によると、回転連結装置と回り止め装置が、固定孔と回り止め孔を有する第一連結片及び第二連結片と、連結ピン及び回転止めピンのみを有していればよく、構造が単純となるため、奥行方向で隣り合う縦梁の連結作業が容易となる。 Further, in the suspended scaffolding device of the present invention, the first connecting member has a first connecting piece extending from the hanging member bracket toward the side opposite to the beam main body, and the second connecting member includes the beam main body as well as the beam main body. It has a second connecting piece extending from the end along the axial direction of the beam body, and the rotary connecting device includes fixing holes respectively formed in the first connecting piece and the second connecting piece, and the first connecting piece. and connecting pins to be inserted into the fixing holes that are vertically opposed to each other in a state in which the pieces and the second connecting pieces are stacked vertically, and the anti-rotation device is attached to each of the first connecting piece and the second connecting piece. A detent hole may be formed, and a detent pin may be inserted into the detent hole that is vertically opposed to the first connecting piece and the second connecting piece in a state of being vertically overlapped. According to this configuration, the rotation connecting device and the anti-rotation device only need to have the first connecting piece and the second connecting piece having the fixing hole and the anti-rotation hole, and the connecting pin and the anti-rotation pin. Since it is simple, it becomes easy to connect longitudinal beams adjacent in the depth direction.

According to this configuration, since the pair of connecting holes are arranged side by side when viewed from the depth direction, the operator can reduce the amount of leaning forward when inserting each connecting pin into each connecting hole. Moreover, if each rotating piece is oriented vertically, the horizontal width of each rotating piece becomes the short side, so each rotating piece does not interfere with the storage and transportation of the vertical beam.

また、本発明の吊り足場装置では、前記第一回転片及び前記第二回転片は、横向き姿勢で、前記第一突出片及び前記第二突出片に形成されたピン孔と対向する溝又は孔を有しており、前記第一回転片及び前記第二回転片は、互いに対向する前記ピン孔と前記溝又は前記孔に挿入される規制ピンによって、横向き姿勢で固定されてもよい。この構成によると、簡易な構造で回転片を横向き姿勢に固定できる。 Further, in the suspended scaffolding device of the present invention, the first rotating piece and the second rotating piece have grooves or holes facing pin holes formed in the first protruding piece and the second protruding piece in a lateral posture. , and the first rotating piece and the second rotating piece may be fixed in a lateral posture by the pin hole and the groove facing each other or a regulating pin inserted into the hole.

According to this configuration, when the connecting hole of the first rotating piece and the connecting hole of the second rotating piece are vertically opposed, the rotating shaft of each rotating piece or the holding cylinder for rotatably holding the rotating shaft is attached to each rotating piece. Each can be accommodated in the accommodation groove. Then, since the overlapping area of the first rotating piece and the second rotating piece can be increased by the depth of the accommodation groove, even if the short side of each rotating piece is shortened in order to facilitate storage and transportation of the vertical beam, It is possible to sufficiently secure the connection strength between the rotating pieces.

また、本発明の吊り足場装置の組立方法は、前記奥側の縦梁を幅方向に沿わせつつ、前記手前側の縦梁と前記奥側の縦梁の前記固定孔を対向させた状態で、前記固定孔に前記連結ピンを挿入して、前記奥側の縦梁を前記手前側の縦梁に対して水平方向に回転自在に連結する工程と、前記奥側の縦梁を前記手前側の縦梁に対して直列になるように回転させてから、前記手前側の縦梁と前記奥側の縦梁の前記回り止め孔に前記回転止めピンを挿入して、前記奥側の縦梁を前記手前側の縦梁に対して回転不能に固定する工程とを含んでもよい。この構成によると、奥側の縦梁を吊り足場装置の幅方向に沿わせた状態で、奥側の縦梁を手前側の縦梁に対して水平方向に回転自在に連結するので、2人の作業者で奥側の縦梁を保持しながら、奥側の縦梁を手前側の縦梁に連結する作業を行うことができる。よって、吊り足場装置の組立作業の安全性が向上する。 Further, in the method for assembling the hanging scaffolding device of the present invention, the fixing holes of the front side vertical beam and the back side vertical beam are opposed to each other while the back side vertical beam is aligned in the width direction. a step of inserting the connecting pin into the fixing hole to connect the back vertical beam to the front vertical beam so as to be rotatable in the horizontal direction; After rotating so as to be in series with the longitudinal beam of the front side and the back side vertical beam, the rotation stop pin is inserted into the anti-rotation hole of the back side vertical beam non-rotatably fixed to said front longitudinal beam. According to this configuration, the longitudinal beam on the far side is horizontally rotatably connected to the longitudinal beam on the front side in a state in which the longitudinal beam on the far side extends along the width direction of the suspended scaffolding device, so that two people can use the scaffolding. While holding the longitudinal beam on the back side, the operator can perform the work of connecting the longitudinal beam on the back side to the longitudinal beam on the front side. Therefore, the safety of the assembly work of the suspended scaffolding device is improved.

また、本発明の吊り足場装置の組立方法では、手前側の縦梁の第一連結部材の第一回転片と、奥側の縦梁の第二連結部材の第二回転片とをそれぞれ横向き姿勢とする工程と、奥側の縦梁を幅方向に沿わせつつ、手前側の縦梁の第一回転片と奥側の縦梁の第二回転片の一方の連結孔を対向させた状態で、一方の連結孔に第一連結ピンを挿入して、奥側の縦梁を手前側の縦梁に対して水平方向に回転自在に連結する工程と、奥側の縦梁を手前側の縦梁に対して直列になるように回転させてから、手前側の縦梁の第一回転片と奥側の縦梁の第二回転片の他方の連結孔を対向させた状態で、他方の連結孔に第二連結ピンを挿入して、奥側の縦梁を手前側の縦梁に対して回転不能に固定する工程とを含んでもよい。この構成によると、奥側の縦梁を吊り足場装置の幅方向に沿わせた状態で、奥側の縦梁を手前側の縦梁に対して水平方向に回転自在に連結するので、2人の作業者で奥側の縦梁を保持しながら、奥側の縦梁を手前側の縦梁に連結する作業を行うことができる。よって、吊り足場装置の組立作業の安全性が向上する。 In addition, in the method of assembling the suspended scaffolding device of the present invention, the first rotating piece of the first connecting member of the longitudinal beam on the front side and the second rotating piece of the second connecting member of the longitudinal beam on the back side are placed in a horizontal posture. and a step in which one connecting hole of the first rotating piece of the longitudinal beam on the front side and the second rotating piece of the longitudinal beam on the back side are opposed to each other while the longitudinal beam on the back side is aligned in the width direction. a step of inserting a first connecting pin into one of the connecting holes to horizontally rotatably connect the back vertical beam to the front vertical beam; Rotate it so that it is in line with the beam, then connect the other connection with the other connection hole of the first rotation piece of the front vertical beam and the second rotation piece of the back vertical beam facing each other and inserting a second connecting pin into the hole to non-rotatably fix the rear longitudinal beam to the front longitudinal beam. According to this configuration, the longitudinal beam on the far side is horizontally rotatably connected to the longitudinal beam on the front side in a state in which the longitudinal beam on the far side extends along the width direction of the suspended scaffolding device, so that two people can use the scaffolding. While holding the longitudinal beam on the back side, the operator can perform the work of connecting the longitudinal beam on the back side to the longitudinal beam on the front side. Therefore, the safety of the assembly work of the suspended scaffolding device is improved.

また、図2(A),(B)に示すように、上弦材50は、梁本体5の長手方向に沿って延びる平板状の平板部50aと、平板部50aの上面から梁本体5の長手方向に沿って起立する一対の位置決め片50b,50bと、平板部50aの下面に設けられて束材52と斜材53を保持する保持片50cとを備える。さらに、図2(B)に示すように、平板部50aにおける位置決め片50b,50bよりも幅方向で外側の部分には、それぞれ幅方向で隣り合う一対の引掛け孔50d,50dが、梁本体5の長手方向に沿って所定の間隔で3箇所に配置されている。そして、この引掛け孔50dに、後述する中間梁10の各端部に設けられた引掛け部12を挿入することで、縦梁2に中間梁10を連結できる。 As shown in FIGS. 2A and 2B, the upper chord member 50 includes a flat plate portion 50a extending along the longitudinal direction of the beam main body 5 and extending from the upper surface of the flat plate portion 50a to the longitudinal direction of the beam main body 5.

The intermediate beam 10 can be connected to the longitudinal beam 2 by inserting hook portions 12 provided at respective ends of the intermediate beam 10, which will be described later, into the hook holes 50d.

つづいて、結合部材Jについて詳細に説明する。本実施の形態の結合部材Jは、図3に示すように、梁本体5の一端に設けられてチェーンCを取付け可能な吊り材ブラケット6と、吊り材ブラケット6の反梁本体側に設けられる第一連結部材7とを有する。 Next, the connecting member J will be described in detail. As shown in FIG. 3, the connecting member J of the present embodiment is provided at one end of the beam body 5 to which the chain C can be attached. and a first connecting member 7 .

本実施の形態の吊り材ブラケット6は、図3(A)に示すように、梁本体5の上弦材50及び下弦材51の一端にそれぞれ連結される上下一対のプレート60,61と、上側プレート60と下側プレート61とを連結する円筒状の接続部62とを備える。 As shown in FIG. 3A, the hanger bracket 6 of the present embodiment includes a pair of upper and lower plates 60 and 61 connected to one end of the upper chord member 50 and the lower chord member 51 of the beam body 5, respectively, and an upper plate. A cylindrical connecting portion 62 connecting 60 and the lower plate 61 is provided.

なお、本実施の形態の各プレート60,61は、図3(A)に示すように、正方形の板の4つの角を切り落としてできる8角形状に形成されているが、各プレート60,61の形状は一例であって、上記形状には限定されず、円形や四角形であってもよい。また、接続部62の形状も円筒状には限定されず、例えば、角筒状であってもよい。 As shown in FIG. 3A, each of the plates 60 and 61 of this embodiment is formed in an octagonal shape by cutting off four corners of a square plate. The shape of is an example, and is not limited to the above shape, and may be a circle or a square. Also, the shape of the connection portion 62 is not limited to a cylindrical shape, and may be, for example, a square tube shape.

また、本実施の形態では、吊り材ブラケット6は、梁本体5に対して溶接によって一体的に取付けされているが、吊り材ブラケット6の梁本体5への取付方法は特に限定されず、例えば、吊り材ブラケット6は、ボルトとナットとによって梁本体5に対して着脱可能に取付けられてもよい。 In the present embodiment, the suspension material bracket 6 is integrally attached to the beam body 5 by welding, but the method of attaching the suspension material bracket 6 to the beam body 5 is not particularly limited. , the hanging member bracket 6 may be detachably attached to the beam body 5 with bolts and nuts.

また、上側プレート60の中央には、図3(A)に示すように、チェーンCの下端を連結可能なチェーン固定孔63が設けられている。詳細には、本実施の形態のチェーン固定孔63は、図3(A)に示すように、チェーンCの挿通を許容する中心孔部63aと、中心孔部63aから平面視で図中上下左右に延びる4本の突条孔部63bとを有して十字状に形成されている。さらに、上側プレートには、各突条孔部63bを突条孔部63bの延長方向で横切る切欠き63cが形成されている。 Further, in the center of the upper plate 60, as shown in FIG. 3A, a chain fixing hole 63 to which the lower end of the chain C can be connected is provided. Specifically, as shown in FIG. 3A, the chain fixing hole 63 of the present embodiment has a central hole portion 63a through which the chain C is inserted, and a vertical and horizontal direction from the central hole portion 63a in a plan view. It is formed in a cross shape having four projecting streak holes 63b extending inward. Further, the upper plate is formed with notches 63c that cross each of the protrusion holes 63b in the extending direction of the protrusion holes 63b.

ここで、吊り材ブラケット6に、チェーンCの下端を取付ける手順について説明する。まず、中心孔部63aにチェーンCを挿通した状態で、チェーンCを横移動させて任意の突条孔部63bに挿入する。この際、突条孔部63bの幅は、チェーンCを構成する各リングCaの厚みよりも広く横幅よりも狭くなるように設定されているので、チェーンCは、突条孔部63bに挿入されると、上側プレート60よりも上方のリングCaと下方のリングCaとが上側プレート60に当接して上下方向の移動が規制される。 Here, the procedure for attaching the lower end of the chain C to the hanging member bracket 6 will be described. First, while the chain C is inserted through the center hole 63a, the chain C is laterally moved and inserted into an arbitrary projecting hole 63b. At this time, the width of the projection hole portion 63b is set to be wider than the thickness of each ring Ca constituting the chain C and narrower than the lateral width thereof, so that the chain C is inserted into the projection hole portion 63b. Then, the ring Ca above the upper plate 60 and the ring Ca below the upper plate 60 come into contact with the upper plate 60, and movement in the vertical direction is restricted.

次に、図4に示すように、突条孔部63bにチェーンCを挿入した状態で、切欠き63cにチェーン固定プレート64を挿入し、チェーン固定プレート64の上端側に設けられた孔64aとチェーンCのリングCa内に拘束バンド65を通し、チェーン固定プレート64とチェーンCを拘束バンド65で固定する。これにより、チェーンCの横方向の移動も規制されるので、チェーンCの下端が吊り材ブラケット6に取付けられる。 Next, as shown in FIG. 4, the chain fixing plate 64 is inserted into the notch 63c with the chain C inserted into the protrusion hole 63b, and the hole 64a provided on the upper end side of the chain fixing plate 64 A restraining band 65 is passed through the ring Ca of the chain C, and the chain fixing plate 64 and the chain C are fixed with the restraining band 65.例文帳に追加Since this restricts the lateral movement of the chain C, the lower end of the chain C is attached to the hanger bracket 6 .

このように、本実施の形態の吊り材ブラケット6は、十字状のチェーン固定孔63を有していて、4つの突条孔部63bのいずれかに挿入されたチェーンCを保持できる。よって、チェーンCの水平位置が吊り材ブラケット6の水平位置から多少ずれていても、チェーンCの取付位置を微調整できる。 Thus, the suspension member bracket 6 of the present embodiment has the cross-shaped chain fixing hole 63 and can hold the chain C inserted into any one of the four projecting hole portions 63b. Therefore, even if the horizontal position of the chain C is slightly deviated from the horizontal position of the hanger bracket 6, the mounting position of the chain C can be finely adjusted.

ただし、上述した吊り材ブラケット6の構成は一例であって、吊り材としてのチェーンCを取付け可能である限りにおいて、吊り材ブラケット6の構成は、特に限定されない。また、縦梁2を吊持する吊り材はチェーンCでなくともよく、例えば、吊り材はワイヤロープであってもよい。 However, the configuration of the suspension member bracket 6 described above is an example, and the configuration of the suspension member bracket 6 is not particularly limited as long as the chain C as a suspension member can be attached. Moreover, the suspension material for suspending the vertical beam 2 may not be the chain C, and the suspension material may be, for example, a wire rope.

つづいて、本実施の形態の第一連結部材7は、図3に示すように、吊り材ブラケット6の上側プレート60及び下側プレート61からそれぞれ反梁本体側に向けて延びる矩形状の平板で形成された上下一対の第一連結片70,70を備える。また、各第一連結片70には、図3(A)に示すように、梁本体5側から順に第一連結片70の延長方向に沿って並べて配置されて互いに上下方向で対向する固定孔70aと回り止め孔70bがそれぞれ形成されている。 Next, as shown in FIG. 3, the first connecting member 7 of the present embodiment is a rectangular flat plate extending from the upper plate 60 and the lower plate 61 of the hanging member bracket 6 toward the opposite side of the beam main body. A pair of upper and lower first connecting pieces 70, 70 are formed. In addition, as shown in FIG. 3A, each first connecting piece 70 has fixing holes arranged side by side along the extending direction of the first connecting piece 70 in order from the beam body 5 side and opposed to each other in the vertical direction. 70a and a detent hole 70b are formed respectively.

さらに、図3(B)に示すように、上下一対の第一連結片70,70間には、互いに対向する固定孔70a,70aに内部が連通する第一ガイド筒71と、互いに対向する回り止め孔70b,70bに内部が連通する第二ガイド筒72とが、それぞれ架け渡されている。ただし、これらのガイド筒71,72は省略されてもよい。 Further, as shown in FIG. 3(B), between the pair of upper and lower first connecting pieces 70, 70 are a first guide tube 71 whose inside communicates with the fixing holes 70a, 70a facing each other, and a rotation guide tube 71 facing each other. A second guide cylinder 72 whose inside communicates with the stop holes 70b, 70b is bridged over them. However, these guide cylinders 71 and 72 may be omitted.

また、図3(A)に示すように、上側の第一連結片70における固定孔70aよりも吊り材ブラケット6側に位置する部分に、第一連結片70の幅方向に並べて配置される一対の引掛け孔70c,70cが形成されている。詳しくは後述するが、この引掛け孔70cに横梁3の各端部に設けられた引掛け部31を挿入することで、横梁3の一端を第一連結部材7に連結できるようになっている。 Further, as shown in FIG. 3A, a pair of the first connecting pieces 70 arranged side by side in the width direction of the upper first connecting piece 70 is positioned closer to the suspension member bracket 6 than the fixing hole 70a. hooking holes 70c, 70c are formed. Although details will be described later, one end of the horizontal beam 3 can be connected to the first connecting member 7 by inserting the hooking portion 31 provided at each end of the horizontal beam 3 into the hooking hole 70c. .

なお、本実施の形態では、第一連結片70の形状は、図4(A)に示すように、先端側(図中右側)の角が面取りされた矩形状とされているが、第一連結片70の形状は特に限定されない。 In the present embodiment, the shape of the first connecting piece 70 is a rectangular shape with chamfered corners on the tip side (right side in the drawing) as shown in FIG. The shape of the connecting piece 70 is not particularly limited.

つづいて、本実施の形態の第二連結部材8は、図2,図5に示すように、梁本体5の他端からそれぞれ反梁本体側に向けて延びる矩形状の平板で形成された上下一対の第二連結片80,80を備える。なお、本実施の形態では、第二連結部材8は、梁本体5に対して溶接によって一体的に連結されているが、第二連結部材8の梁本体5に対する取付方法は特に限定されず、例えば、第二連結部材8は、ボルトとナットで梁本体5に対して着脱可能に取付けられてもよい。 Next, as shown in FIGS. 2 and 5, the second connecting member 8 of the present embodiment is formed of a rectangular flat plate extending from the other end of the beam body 5 toward the opposite side of the beam body. A pair of second connecting pieces 80, 80 are provided. In the present embodiment, the second connecting member 8 is integrally connected to the beam body 5 by welding, but the method of attaching the second connecting member 8 to the beam body 5 is not particularly limited. For example, the second connecting member 8 may be detachably attached to the beam body 5 with bolts and nuts.

また、各第二連結片80には、図2,図5に示すように、梁本体5側から順に第二連結片80の延長方向に沿って並べて配置されて互いに上下方向で対向する回り止め孔80aと固定孔80bがそれぞれ形成されている。 As shown in FIGS. 2 and 5, each second connecting piece 80 has anti-rotation stoppers arranged side by side along the extension direction of the second connecting piece 80 in order from the beam body 5 side and opposed to each other in the vertical direction. A hole 80a and a fixing hole 80b are formed respectively.

さらに、一対の第二連結片80,80の間隔は、第二連結片80,80の間に一対の第一連結片70,70を嵌合可能な長さに設定されている。加えて、第二連結片80の回り止め孔80aと固定孔80bは、第二連結片80,80の間に一対の第一連結片70,70が嵌合されると、それぞれ第一連結片70の回り止め孔70bと固定孔70aに対向する位置に設けられている。 Furthermore, the interval between the pair of second connecting pieces 80,80 is set to a length that allows the pair of first connecting pieces 70,70 to fit between the second connecting pieces 80,80. In addition, when the pair of first connecting pieces 70, 70 are fitted between the second connecting pieces 80, 80, the anti-rotation hole 80a and the fixing hole 80b of the second connecting piece 80 respectively 70 is provided at a position facing the anti-rotation hole 70b and the fixing hole 70a.

そのため、図6に示すように、吊り足場装置1の奥行方向で一方側(図6中左側)の縦梁2の一対の第一連結片70,70を、他方側(図6中右側)の一対の第二連結片80,80間に嵌合し、第一連結片70と第二連結片80を上下に重ねて、対向する各固定孔70a,80bと各回り止め孔70b,80aに連結ピンP1及び回転止めピンP2をそれぞれ挿入することで、2つの縦梁2,2を直列に連結できる。 Therefore, as shown in FIG. 6, the pair of first connecting pieces 70, 70 of the vertical beam 2 on one side (left side in FIG. 6) in the depth direction of the suspended scaffolding device 1 is connected to the other side (right side in FIG. 6). It is fitted between a pair of second connecting pieces 80, 80, the first connecting piece 70 and the second connecting piece 80 are stacked vertically, and connected to the opposing fixing holes 70a, 80b and the anti-rotation holes 70b, 80a. The two longitudinal beams 2, 2 can be connected in series by inserting the pin P1 and the detent pin P2 respectively.

なお、本実施の形態では、一対の第一連結片70,70を一対の第二連結片80,80間に嵌合しているが、一対の第一連結片70,70の間隔を、第一連結片70,70間に一対の第二連結片80,80を嵌合可能な長さに設定して、一対の第二連結片80,80を一対の第一連結片70,70間に嵌合するようにしてもよい。 In this embodiment, the pair of first connecting pieces 70, 70 are fitted between the pair of second connecting pieces 80, 80, but the gap between the pair of first connecting pieces 70, 70 is A pair of second connecting pieces 80, 80 are set to a length that allows fitting between the one connecting pieces 70, 70, and the pair of second connecting pieces 80, 80 are inserted between the pair of first connecting pieces 70, 70. You may make it fit.

以上のように、本実施の形態の結合部材Jは、梁本体5の一端に設けられる吊り材ブラケット6と、吊り材ブラケット6の反梁本体側に設けられる第一連結部材7とを備えており、第一連結部材7には、奥行方向で隣り合う縦梁2の第二連結部材8と連結可能な固定孔70a及び回り止め孔70bと、横梁3を連結可能な引掛け孔70cが設けられている。 As described above, the connecting member J of the present embodiment includes the suspension member bracket 6 provided at one end of the beam body 5 and the first connecting member 7 provided on the side of the suspension member bracket 6 opposite to the beam body. The first connecting member 7 is provided with fixing holes 70a and anti-rotation holes 70b that can be connected to the second connecting members 8 of the longitudinal beams 2 adjacent in the depth direction, and hook holes 70c that can connect the horizontal beams 3. It is

つまり、本実施の形態では、図2に示すように、吊り材としてのチェーンCを取付け可能な吊り材ブラケット6と、他の縦梁2及び横梁3と連結可能な第一連結部材7とが、縦梁2の長手方向に沿って直列に配置されている。 That is, in the present embodiment, as shown in FIG. 2, a suspension material bracket 6 to which a chain C as a suspension material can be attached, and a first connecting member 7 that can be connected to other vertical beams 2 and horizontal beams 3 are provided. , are arranged in series along the longitudinal direction of the longitudinal beam 2 .

したがって、結合部材に吊り材への連結と縦梁と横梁を連結する機能を集約した従来の吊り足場装置と比較して、本実施の形態の縦梁2では、吊り材としてのチェーンCに連結される吊り材ブラケット6と、縦梁2に横梁3を連結する第一連結部材7とを分離して直列に設けているので、結合部材Jの横幅が短くなる。 Therefore, compared to the conventional suspended scaffolding device in which the connecting member has the function of connecting to the hanging member and connecting the vertical beam and the horizontal beam, the vertical beam 2 of the present embodiment is connected to the chain C as the hanging member. Since the hanging material bracket 6 and the first connecting member 7 connecting the horizontal beam 3 to the vertical beam 2 are separated and provided in series, the width of the connecting member J is reduced.

よって、本実施の形態では、縦梁2が吊り材ブラケット6と第一連結部材7とを有する結合部材Jを備えた状態であっても、縦梁2における結合部材Jの横幅が他の部分の横幅に比べてそれ程広くならないため、結合部材Jが、かさばることが無く、縦梁2の保管や運搬の邪魔になりづらい。 Therefore, in the present embodiment, even when the longitudinal beam 2 is provided with the connecting member J having the hanging material bracket 6 and the first connecting member 7, the width of the connecting member J in the longitudinal beam 2 is the same as that of the other portion. Since the width of the joint member J is not so large compared to the width of the joint member J, the joint member J is not bulky and does not easily interfere with the storage and transportation of the longitudinal beam 2. - 特許庁

Between the beam bodies 5, 5 of the longitudinal beams 2, 2, three intermediate beams 10 are bridged with a predetermined interval.

以下、横梁3と中間梁10の構成について詳細に説明するが、本実施の形態の横梁3と中間梁10は、同一の構成であるため、まとめて説明する。本実施の形態の横梁3及び中間梁10は、図7に示すように、梁本体30(11)と、梁本体30(11)の長手方向の両端部からそれぞれ下向きに突出するピン状の引掛け部31(12)とを備える。また、梁本体30(11)には、幅方向中央から起立して長手方向に沿って延びる位置決め片30a(11a)が設けられている。 The configurations of the horizontal beam 3 and the intermediate beam 10 will be described in detail below. Since the horizontal beam 3 and the intermediate beam 10 of the present embodiment have the same configuration, they will be collectively described. As shown in FIG. 7, the horizontal beams 3 and the intermediate beams 10 of the present embodiment are pin-shaped pulleys protruding downward from beam main bodies 30 (11) and both ends in the longitudinal direction of the beam main bodies 30 (11). and a hanging portion 31 (12). Further, the beam body 30 (11) is provided with a positioning piece 30a (11a) that stands up from the center in the width direction and extends along the longitudinal direction.

そして、横梁3の各端部に設けられた引掛け部31を幅方向で隣り合う縦梁2,2の各第一連結片70の引掛け孔70cにそれぞれ挿入することで、横梁3は、図1に示すように、幅方向で隣り合う縦梁2,2の第一連結部材7,7間に架け渡される。 By inserting the hook portions 31 provided at each end of the horizontal beam 3 into the hook holes 70c of the first connecting pieces 70 of the vertical beams 2, 2 adjacent in the width direction, the horizontal beam 3 can be As shown in FIG. 1, it spans between the first connecting members 7, 7 of the longitudinal beams 2, 2 adjacent in the width direction.

さらに、中間梁10の各端部に設けられた引掛け部12を幅方向で隣り合う縦梁2,2の各梁本体5に設けられた引掛け孔50dにそれぞれ挿入することで、中間梁10は、図1に示すように、幅方向で隣り合う縦梁2,2の梁本体5,5間に架け渡される。 Furthermore, by inserting the hooking portions 12 provided at each end of the intermediate beam 10 into the hooking holes 50d provided in the beam main bodies 5 of the longitudinal beams 2, 2 adjacent in the width direction, the intermediate beam 10 is bridged between the beam bodies 5, 5 of the longitudinal beams 2, 2 adjacent in the width direction, as shown in FIG.

また、本実施の形態では、幅方向で隣り合う縦梁2,2の梁本体5,5間に、3本の中間梁10が架け渡されているが、中間梁10の数は特に限定されない。 Further, in the present embodiment, three intermediate beams 10 are bridged between the beam bodies 5, 5 of the longitudinal beams 2, 2 adjacent in the width direction, but the number of the intermediate beams 10 is not particularly limited. .

なお、上述した横梁3及び中間梁10の構成は、一例であって、上述した構成には限定されず、横梁3及び中間梁10は、引掛け部31(12)を引掛け孔70c(50d)に挿入する以外の方法で、幅方向で隣り合う縦梁2,2間に架け渡されてもよい。また、横梁3と中間梁10は異なる構成とされてもよいが、本例のように同一の構成とすると、吊り足場装置1を構成する部品の種類を削減できるので、製造コストを低減できる。 The configuration of the horizontal beam 3 and the intermediate beam 10 described above is an example, and is not limited to the configuration described above. ), it may be bridged between the longitudinal beams 2, 2 adjacent in the width direction. Further, the horizontal beams 3 and the intermediate beams 10 may have different structures, but if they have the same structure as in this example, the types of parts constituting the suspended scaffolding device 1 can be reduced, so the manufacturing cost can be reduced.

つづいて、幅方向で隣り合う縦梁2,2間に架け渡される足場板4について詳細に説明する。本実施の形態の足場板4は、木製の矩形板材で構成されている。なお、足場板4の材料は、必要な強度が確保される限りにおいて特に限定されないが、足場板4を木製とすると軽量となるので、足場板4を持ち運びしやすく、足場板4の設置作業が容易となる。また、足場板4を金属製とする場合には、足場板4は、軽量な金属、例えば、アルミニウム等で形成されるのが好ましい。 Next, a detailed description will be given of the scaffolding board 4 that spans between the longitudinal beams 2, 2 adjacent in the width direction. The scaffold board 4 of this embodiment is made of a rectangular wooden board. The material of the scaffolding board 4 is not particularly limited as long as the necessary strength is ensured. easier. Moreover, when the scaffolding board 4 is made of metal, the scaffolding board 4 is preferably made of a lightweight metal such as aluminum.

そして、本実施の形態では、4枚の足場板4が、図1に示すように、奥行方向で隣り合う横梁3と中間梁10の間と、中間梁10,10同士の間の位置に設置されている。この際、各足場板4は、各縦梁2の梁本体5の平板部50aと横梁3の梁本体30と中間梁10の梁本体11上に載置されて、各縦梁2に設けられた位置決め片50bと、横梁3に設けられた位置決め片30a又は中間梁10に設けられた位置決め片11aに外周を囲われた状態になる。すると、足場板4の水平方向の移動が規制されるため足場板4の水平方向のずれが防止される。 In this embodiment, as shown in FIG. 1, four scaffolding boards 4 are installed at positions between the lateral beams 3 and the intermediate beams 10 adjacent in the depth direction and between the intermediate beams 10, 10. It is At this time, each scaffold board 4 is placed on the flat plate portion 50a of the beam body 5 of each vertical beam 2, the beam body 30 of the horizontal beam 3, and the beam body 11 of the intermediate beam 10, and is provided on each vertical beam 2. The outer periphery is surrounded by the positioning piece 50b and the positioning piece 30a provided on the horizontal beam 3 or the positioning piece 11a provided on the intermediate beam 10. As shown in FIG. Then, since the horizontal movement of the scaffolding board 4 is restricted, the horizontal displacement of the scaffolding board 4 is prevented.

なお、幅方向で隣り合う一対の縦梁2,2間に設置される足場板4の枚数は特に限定されないが、幅方向で隣り合う一対の縦梁2,2間への足場板4の設置枚数を増やすほど、足場板4の1枚当たりの面積が小さくなるので、足場板4の持ち運びがしやすく、足場板4の設置作業が容易になる。さらに、足場板4の面積が小さいと、作業者が足場板4上に乗った際に足場板4が撓みにくくなるので、足場板4の強度が向上する。ただし、幅方向で隣り合う一対の縦梁2,2間への足場板4の設置枚数を増やすとその分だけ吊り足場装置1の組立工程が増えるので、足場板4の設置枚数は4枚程度とするのが好ましい。 The number of scaffolding boards 4 installed between the pair of vertical beams 2, 2 adjacent in the width direction is not particularly limited, but the number of scaffolding boards 4 installed between the pair of vertical beams 2, 2 adjacent in the width direction As the number of scaffolding boards 4 is increased, the area of each scaffolding board 4 becomes smaller, so that the scaffolding boards 4 are easy to carry and the installation work of the scaffolding boards 4 is facilitated. Furthermore, when the area of the scaffolding board 4 is small, the scaffolding board 4 is less likely to bend when a worker gets on the scaffolding board 4, so the strength of the scaffolding board 4 is improved. However, if the number of scaffolding boards 4 installed between a pair of longitudinal beams 2, 2 adjacent in the width direction is increased, the number of assembly steps of the hanging scaffolding device 1 will increase accordingly, so the number of scaffolding boards 4 installed is about four. is preferable.

つづいて、本実施の形態の吊り足場装置1の組立方法について、図8から図12を使用して詳細に説明する。以下、吊り足場装置1上にいる作業者から見て、吊り足場装置1の奥行方向で、床面積を拡張する側(図8中下側)を奥側と称し、その反対側(図8中上側)を手前側と称して説明する。 Next, a method for assembling the suspended scaffolding device 1 of the present embodiment will be described in detail with reference to FIGS. 8 to 12. FIG. Hereinafter, when viewed from a worker on the suspended scaffolding device 1, the side extending the floor area in the depth direction of the suspended scaffolding device 1 (the lower side in FIG. 8) is referred to as the back side, and the opposite side (the The upper side) will be referred to as the front side.

まず、奥行方向と幅方向に複数の足場ユニットAを接続して構成される吊り足場装置1を地上で組み立てる。この際、奥行方向で最も手前側に配置される縦梁2の手前側の端部と、この縦梁2の手前側端同士の間に架け渡される横梁3は、縦梁2の手前側端の第二連結部材8に連結された結合部材Jによって連結されている。なお、吊り足場装置1の手前側の終端に位置する縦梁2と横梁3の連結には梁本体5とは連結されていない単体の結合部材Jによって行われればよい。 First, a hanging scaffolding device 1 configured by connecting a plurality of scaffolding units A in the depth direction and the width direction is assembled on the ground. At this time, the front end portion of the vertical beam 2 arranged on the frontmost side in the depth direction and the horizontal beam 3 bridged between the front side ends of the vertical beam 2 are connected by a connecting member J connected to the second connecting member 8 of the . The connection between the vertical beam 2 and the horizontal beam 3 located at the front end of the suspended scaffolding device 1 may be performed by a single connecting member J that is not connected to the beam main body 5 .

そして、地上で組み立てた吊り足場装置1の各足場ユニットA(以下、「既設の足場ユニットA」とする。)に設けられた吊り材ブラケット6に、上端が建築物又は構造物に取付けられたチェーンCの下端を連結し、チェーンCを重機やチェーンブロックで巻き上げることで、図8に示すように、吊り足場装置1を建築物又は構造物に吊持させる。 Then, the upper end of the hanging material bracket 6 provided in each scaffolding unit A (hereinafter referred to as "existing scaffolding unit A") of the suspended scaffolding device 1 assembled on the ground was attached to the building or structure. By connecting the lower end of the chain C and winding up the chain C with a heavy machine or a chain block, the suspended scaffolding device 1 is suspended from a building or structure as shown in FIG.

本実施の形態では、吊り足場装置1は、図8に示すように、幅方向に3列、奥行方向に2列配置された6つの既設の足場ユニットAで構成されており、幅方向で隣接する既設の足場ユニットAは、縦梁2を互いに共有している。なお、吊り足場装置1を構成する既設の足場ユニットAの数は、必要に応じて適宜決定されればよく、少なくとも1つあればよい。なお、図8から図12では、吊り足場装置1の構造を理解しやすくするために、チェーンCを省略している。 In this embodiment, as shown in FIG. 8, the suspended scaffolding device 1 is composed of six existing scaffolding units A arranged in three rows in the width direction and two rows in the depth direction. existing scaffolding units A share the vertical beams 2 with each other. The number of existing scaffolding units A constituting the suspended scaffolding device 1 may be appropriately determined according to need, and at least one unit is sufficient. 8 to 12, the chain C is omitted in order to facilitate understanding of the structure of the suspended scaffolding device 1. As shown in FIG.

次に、既設の足場ユニットAの縦梁2である奥行方向で手前側の縦梁2に対して奥側の縦梁2を直列に連結する。詳細には、まず、図9(A)に示すように、奥側の縦梁2を吊り足場装置1の幅方向に沿わせた状態で、奥側の縦梁2の第二連結部材8の一対の第二連結片80間に手前側の縦梁2の第一連結部材7の一対の第一連結片70を嵌合して各固定孔70a,80bを対向させる。その状態で、対向する各固定孔70a,80bに連結ピンP1を挿入すると、奥側の縦梁2は吊り足場装置1の幅方向に沿った状態で手前側の縦梁2に対して水平方向に回転自在に連結される。この際、第一連結片70,70間には、各固定孔70aと連通する第一ガイド筒71が架け渡されている。これにより、連結ピンP1の挿入が第一ガイド筒71によってガイドされるので、連結ピンP1を固定孔70a,80bにスムーズに挿入できる。 Next, the longitudinal beam 2 on the back side is connected in series with the vertical beam 2 on the front side in the depth direction, which is the vertical beam 2 of the existing scaffolding unit A. Specifically, first, as shown in FIG. 9A, the second connecting member 8 of the back vertical beam 2 is aligned with the back vertical beam 2 along the width direction of the suspended scaffolding device 1. The pair of first connecting pieces 70 of the first connecting member 7 of the vertical beam 2 on the front side is fitted between the pair of second connecting pieces 80 to make the fixing holes 70a and 80b face each other. In this state, when the connecting pin P1 is inserted into each of the fixing holes 70a and 80b facing each other, the vertical beam 2 on the back side is parallel to the vertical beam 2 on the front side while being along the width direction of the suspended scaffolding device 1. rotatably connected to the At this time, a first guide cylinder 71 that communicates with each fixing hole 70a is bridged between the first connecting pieces 70,70. Since the insertion of the connecting pin P1 is guided by the first guide tube 71, the connecting pin P1 can be smoothly inserted into the fixing holes 70a and 80b.

次に、図9(B)に示すように、連結ピンP1を回転軸にして、奥側の縦梁2を手前側の縦梁2に対して直列になる位置まで水平回転させて、第一連結片70の回り止め孔70bと第二連結片80の回り止め孔80aを対向させる。その状態で、対向する回り止め孔70b,80aに回転止めピンP2を挿入すると、奥側の縦梁2が手前側の縦梁2に対して回転不能に固定される。この際、第一連結片70,70間には、各回り止め孔70bと連通する第二ガイド筒72が架け渡されている。これにより、回転止めピンP2の挿入が第二ガイド筒72によってガイドされるので、回転止めピンP2を回り止め孔70b、80aにスムーズに挿入できる。この際、詳細には説明しないが、連結ピンP1及び回転止めピンP2の基端には、第二連結片80の上面に当接する突起(図示せず)が設けられており、連結ピンP1及び回転止めピンP2の下方への抜けが防止される。 Next, as shown in FIG. 9(B), using the connecting pin P1 as a rotation axis, the longitudinal beam 2 on the back side is horizontally rotated to a position where it is in series with the longitudinal beam 2 on the front side, and the first The anti-rotation hole 70b of the connecting piece 70 and the anti-rotation hole 80a of the second connecting piece 80 are made to face each other. In this state, when the anti-rotation pin P2 is inserted into the anti-rotation holes 70b and 80a facing each other, the vertical beam 2 on the far side is non-rotatably fixed to the vertical beam 2 on the front side. At this time, a second guide tube 72 is bridged between the first connecting pieces 70 and 70 and communicates with each anti-rotation hole 70b. As a result, the insertion of the rotation stop pin P2 is guided by the second guide tube 72, so that the rotation stop pin P2 can be smoothly inserted into the rotation stop holes 70b and 80a. At this time, although not described in detail, a projection (not shown) that abuts on the upper surface of the second connecting piece 80 is provided at the proximal ends of the connecting pin P1 and the rotation stop pin P2. The rotation stop pin P2 is prevented from coming off downward.

このように、本実施の形態では、第一連結部材7の第一連結片70と第二連結部材8の第二連結片80にそれぞれ形成される固定孔70a,80bと、第一連結片70と第二連結片80を上下に重ねた状態で上下に対向する固定孔70a,80bに挿入される連結ピンP1とで、奥行方向で隣り合う縦梁2,2のうちで手前側の縦梁2の第一連結部材7に対して奥側の縦梁2の第二連結部材8を水平方向に回転自在に連結する回転連結装置が構成されている。さらに、第一連結部材7の第一連結片70と第二連結部材8の第二連結片80にそれぞれ形成される回り止め孔70b,80aと、第一連結片70と第二連結片80を上下に重ねた状態で上下に対向する回り止め孔70b,80aに挿入される回転止めピンP2とで、奥側の縦梁2が手前側の縦梁2に対して直列に配置された状態で奥側の縦梁2の第二連結部材8を手前側の縦梁2の第一連結部材7に対して回転不能に固定する回り止め装置が構成されている。なお、固定孔70a,80bと回り止め孔70b,80aはそれぞれ逆の位置に配置されてもよい。 Thus, in the present embodiment, the fixing holes 70a and 80b formed in the first connecting piece 70 of the first connecting member 7 and the second connecting piece 80 of the second connecting member 8, respectively, and the first connecting piece 70 and the connecting pin P1 inserted into the fixing holes 70a and 80b facing each other vertically with the second connecting pieces 80 stacked vertically, the longitudinal beam on the front side of the longitudinal beams 2, 2 adjacent in the depth direction. A rotary connecting device is configured for horizontally rotatably connecting the second connecting member 8 of the longitudinal beam 2 on the back side to the first connecting member 7 of the second connecting member. Further, anti-rotation holes 70b and 80a formed in the first connecting piece 70 of the first connecting member 7 and the second connecting piece 80 of the second connecting member 8, respectively, and the first connecting piece 70 and the second connecting piece 80 are The vertical beam 2 on the back side is arranged in series with the vertical beam 2 on the front side by the rotation-stopping pin P2 inserted into the anti-rotation holes 70b and 80a that face each other vertically in a vertically overlapping state. A detent device is configured to non-rotatably fix the second connecting member 8 of the longitudinal beam 2 on the far side to the first connecting member 7 of the longitudinal beam 2 on the front side. Note that the fixing holes 70a, 80b and the anti-rotation holes 70b, 80a may be arranged in opposite positions.

また、上記手順によると、奥側の縦梁2を、吊り足場装置1の幅方向に沿わせた状態で、手前側の縦梁2に対して連結できる。すると、奥側の縦梁2の両端は奥行方向で手前側に位置するため、奥側の縦梁2を手前側の縦梁2に連結する作業を、既に組み上げられた足場ユニットA上で、2人の作業者が縦梁2を保持しながら行うことができる。よって、奥行方向で隣り合う縦梁2,2同士を連結する作業を安全に行うことができる。 Further, according to the above-described procedure, the vertical beam 2 on the far side can be connected to the vertical beam 2 on the front side in a state in which it extends along the width direction of the suspended scaffolding device 1 . Then, since both ends of the back side vertical beam 2 are located on the front side in the depth direction, the work of connecting the back side vertical beam 2 to the front side vertical beam 2 is performed on the already assembled scaffolding unit A, Two workers can do this while holding the longitudinal beam 2 . Therefore, the operation of connecting the vertical beams 2, 2 adjacent in the depth direction can be safely performed.

また、縦梁2の梁本体5の一端には、第一連結部材7を含む結合部材Jが一体的に取付けられている。よって、吊り足場装置1の組立作業中に縦梁2に対して結合部材Jを連結する工程が不要となるので、作業性に優れる。 A connecting member J including a first connecting member 7 is integrally attached to one end of the beam body 5 of the longitudinal beam 2 . Therefore, the process of connecting the connecting members J to the vertical beams 2 during the assembly work of the suspended scaffolding device 1 is not required, so workability is excellent.

さらに、既設の足場ユニットAにおいて、幅方向で平行に配置される手前側の縦梁2に対して、上記作業を繰り返すことで、図10に示すように、奥側の縦梁2が幅方向で平行に配置される。 Furthermore, in the existing scaffolding unit A, by repeating the above operation for the longitudinal beams 2 on the front side that are arranged in parallel in the width direction, as shown in FIG. are arranged parallel to each other.

次に、図11に示すように、幅方向で隣り合う奥側の縦梁2,2の梁本体5の1番手前側に設けられる引掛け孔50dに中間梁10の両端に設けられた引掛け部12をそれぞれ挿入して、1本目の中間梁10を幅方向で隣り合う奥側の縦梁2,2間に架け渡してから、1枚目の足場板4を既設の足場ユニットAの横梁3と1本目の中間梁10とで支持させつつ、縦梁2,2間に架け渡す。 Next, as shown in FIG. 11, the hooks provided at both ends of the intermediate beam 10 are hooked to the hook holes 50d provided on the first front side of the beam body 5 of the longitudinal beams 2, 2 adjacent in the width direction. The first intermediate beam 10 is bridged between the inner longitudinal beams 2, 2 adjacent in the width direction by inserting the portions 12 respectively, and then the first scaffolding board 4 is attached to the cross beam of the existing scaffolding unit A. While being supported by 3 and the first intermediate beam 10, it is bridged between the vertical beams 2,2.

そして、図示しないが、2本目及び3本目の中間梁10と2枚目及び3枚目の足場板4についても同様の手順で、手前側から順に幅方向で隣り合う奥側の縦梁2,2間に架け渡していく。 Then, although not shown, the second and third intermediate beams 10 and the second and third scaffolding boards 4 are also subjected to the same procedure, and the longitudinal beams 2, It spans between the two.

その後、図12に示すように、幅方向で隣り合う奥側の縦梁2,2の第一連結部材7に設けられた引掛け孔70cに横梁3の引掛け部31を挿入して、横梁3を幅方向で隣り合う奥側の縦梁2,2の一端同士の間に架け渡してから、4枚目の足場板4を3本目の中間梁10と横梁3とで支持させつつ、奥行方向で隣り合う奥側の縦梁2,2間に架け渡す。 Thereafter, as shown in FIG. 12, the hooking portions 31 of the horizontal beams 3 are inserted into the hooking holes 70c provided in the first connecting members 7 of the longitudinal beams 2, 2 on the far side adjacent in the width direction, and the horizontal beams are connected to each other. 3 is bridged between one ends of the inner longitudinal beams 2, 2 adjacent in the width direction, and then the fourth scaffolding board 4 is supported by the third intermediate beam 10 and the horizontal beam 3 to increase the depth. It bridges between longitudinal beams 2, 2 on the back side adjacent in the direction.

最後に、図示しないが、奥側の縦梁2の吊り材ブラケット6に、上端が建築物又構造物側に連結されたチェーンCの下端を取付けることで、吊り足場装置1の床面積を拡張できる。 Finally, although not shown, the floor area of the suspended scaffolding device 1 is expanded by attaching the lower end of the chain C whose upper end is connected to the building or structure side to the hanging material bracket 6 of the longitudinal beam 2 on the far side. can.

以上の手順を任意の足場ユニットAから奥行方向に繰り返すことで、本実施の形態の吊り足場装置1は、建築物又は構造物に吊持された状態で、任意の位置まで床面積を拡張できるようになっている。ただし、上述した吊り足場装置1の組立方法は、一例であって、吊り足場装置1を組立可能であれば、上記方法には限定されない。 By repeating the above procedure in the depth direction from an arbitrary scaffolding unit A, the suspended scaffolding device 1 of the present embodiment can extend the floor area to an arbitrary position while being suspended from a building or structure. It's like However, the method for assembling the suspended scaffolding device 1 described above is only an example, and the method is not limited to the above method as long as the suspended scaffolding device 1 can be assembled.

前述したように、本実施の形態の吊り足場装置1は、奥行方向に沿って直列に連結可能であって幅方向で平行に配置される複数の縦梁2と、幅方向で隣り合う縦梁2の一端同士の間に架け渡される横梁3と、幅方向で隣り合う縦梁2,2間に架け渡される足場板4とを備え、縦梁2は、梁本体5と、梁本体5の一端に設けられて縦梁2を吊持する吊り材としてのチェーンCを取付け可能な吊り材ブラケット6と、吊り材ブラケット6の反梁本体側に設けられる第一連結部材7と、梁本体5の他端に設けられて奥行方向で隣り合う縦梁2の第一連結部材7に連結可能な第二連結部材8とを有し、横梁3の各端部は幅方向で隣り合う縦梁2の第一連結部材7にそれぞれ連結されている。 As described above, the suspended scaffolding device 1 of the present embodiment includes a plurality of vertical beams 2 that can be connected in series along the depth direction and are arranged in parallel in the width direction, and vertical beams that are adjacent in the width direction. 2, and scaffolding boards 4 that span between the longitudinal beams 2, 2 adjacent in the width direction. A suspension material bracket 6 provided at one end to which a chain C as a suspension material for suspending the vertical beam 2 can be attached, a first connection member 7 provided on the opposite side of the beam main body of the suspension material bracket 6, and a beam main body 5 It has a second connecting member 8 that is provided at the other end and can be connected to the first connecting member 7 of the longitudinal beam 2 adjacent in the depth direction, and each end of the horizontal beam 3 is adjacent in the width direction. are respectively connected to the first connecting members 7 of the .

この構成によると、吊り材ブラケット6と第一連結部材7が縦梁2の長手方向に沿って直列に配置されるので、結合部材に吊り材への連結と縦梁と横梁を連結する機能を集約した従来の吊り足場装置と比較して、吊り材ブラケット6と第一連結部材7とを有する結合部材Jの横幅を短くできる。 According to this configuration, since the hanging member bracket 6 and the first connecting member 7 are arranged in series along the longitudinal direction of the vertical beam 2, the connecting member has the function of connecting to the hanging member and connecting the vertical beam and the horizontal beam. The lateral width of the joint member J having the hanger bracket 6 and the first connecting member 7 can be shortened compared to the conventional suspended scaffolding device that is concentrated.

よって、本実施の形態では、縦梁2が、吊り材ブラケット6と、第一連結部材7とを有する結合部材Jを備えていても、縦梁2の結合部材Jの横幅が他の部分に比べてそれ程広くならないため、結合部材Jがかさばることが無く、縦梁2の保管や運搬が容易となる。 Therefore, in the present embodiment, even if the longitudinal beam 2 is provided with the connecting member J having the hanging material bracket 6 and the first connecting member 7, the width of the connecting member J of the longitudinal beam 2 is different from that of other portions. Since the joint member J is not so wide as compared to the conventional joint member J, the storage and transportation of the longitudinal beam 2 are facilitated without being bulky.

なお、図示するところでは、本実施の形態の吊り材ブラケット6の横幅は、図3(A)に示すように、梁本体5の横幅よりも若干広くなっているが、例えば、十字状のチェーン固定孔63を縦梁2の軸方向に沿うI字状にするなどして、吊り材ブラケット6の横幅を梁本体5の横幅以下に設定してもよい。このようにすれば、結合部材Jの横幅をさらに短くできるため、縦梁2の保管や運搬がより容易となる。 As shown in the figure, the horizontal width of the hanging member bracket 6 of the present embodiment is slightly wider than the horizontal width of the beam main body 5 as shown in FIG. 3(A). The width of the suspension member bracket 6 may be set equal to or less than the width of the beam body 5 by forming the fixing hole 63 in an I shape along the axial direction of the vertical beam 2 . By doing so, the width of the connecting member J can be further shortened, so that the storage and transportation of the vertical beam 2 become easier.

また、本実施の形態の吊り足場装置1は、奥行方向で隣り合う縦梁2,2のうちで手前側の縦梁2の第一連結部材7に対して奥側の縦梁2の第二連結部材8を水平方向に回転自在に連結する回転連結装置と、奥側の縦梁2が手前側の縦梁2に対して直列に配置された状態で奥側の縦梁2の第二連結部材8を手前側の縦梁2の第一連結部材7に対して回転不能に固定する回り止め装置とを備えている。 Further, in the suspended scaffolding device 1 of the present embodiment, among the vertical beams 2, 2 adjacent in the depth direction, the second connecting member 7 of the vertical beam 2 on the far side with respect to the first connection member 7 of the vertical beam 2 on the front side A rotary coupling device for horizontally rotatably coupling the coupling member 8, and a second coupling of the longitudinal beam 2 on the far side in a state where the longitudinal beam 2 on the far side is arranged in series with the longitudinal beam 2 on the front side. A detent device is provided to fix the member 8 to the first connecting member 7 of the longitudinal beam 2 on the front side so as not to rotate.

そして、本実施の形態の吊り足場装置1では、第一連結部材7は、吊り材ブラケット6から反梁本体側に向けて延びる第一連結片70を有し、第二連結部材8は、梁本体5の他端から梁本体5の軸方向に沿って延びる第二連結片80を有し、回転連結装置が、第一連結片70と第二連結片80にそれぞれ形成される固定孔70a,80bと、第一連結片70と第二連結片80を上下に重ねた状態で上下に対向する固定孔70a,80bに挿入される連結ピンP1とを有し、回り止め装置が、第一連結片70と第二連結片80にそれぞれ形成される回り止め孔70b,80aと、第一連結片70と第二連結片80を上下に重ねた状態で上下に対向する回り止め孔70b,80aに挿入される回転止めピンP2とを有している。 In the suspended scaffolding device 1 of the present embodiment, the first connecting member 7 has the first connecting piece 70 extending from the hanging member bracket 6 toward the side opposite to the beam main body, and the second connecting member 8 has the beam The body 5 has a second connecting piece 80 extending along the axial direction of the beam body 5 from the other end of the beam body 5, and the rotary connecting device includes fixing holes 70a formed in the first connecting piece 70 and the second connecting piece 80, respectively. 80b, and a connecting pin P1 that is inserted into the fixing holes 70a and 80b that are vertically opposed to each other in a state in which the first connecting piece 70 and the second connecting piece 80 are vertically overlapped. The anti-rotation holes 70b and 80a formed in the piece 70 and the second connecting piece 80, respectively, and the anti-rotation holes 70b and 80a that face each other vertically when the first connecting piece 70 and the second connecting piece 80 are stacked vertically. and an inserted rotation stop pin P2.

この構成によると、吊り足場装置1の組立時において、奥側の縦梁2を、吊り足場装置1の幅方向に沿わせた状態で、手前側の縦梁2に対して回転自在に連結できるので、2人の作業者で奥側の縦梁2を保持しながら、奥側の縦梁2を手前側の縦梁2に連結する作業を行うことができる。よって、奥行方向で隣り合う縦梁2,2同士の連結作業を安全に行うことができる。 According to this configuration, when the suspended scaffolding device 1 is assembled, the longitudinal beams 2 on the far side can be rotatably connected to the longitudinal beams 2 on the front side in a state in which they are aligned along the width direction of the suspended scaffolding device 1. Therefore, two workers can connect the back vertical beam 2 to the front vertical beam 2 while holding the back vertical beam 2 . Therefore, the work of connecting the vertical beams 2, 2 adjacent in the depth direction can be safely performed.

The connecting holes 802a on the right side (right side in the figure) when viewed from the beam main body 5 side are opposed to each other. In this state, when the second connecting pin P5 is inserted into the opposing connecting holes 702a and 802a, the longitudinal beam 200 on the far side is non-rotatably fixed to the longitudinal beam 200 on the front side.

なお、本実施の形態では、図18に示すように、奥側の縦梁200を、手前側の縦梁200の図中左側に畳んだ状態から、手前側の縦梁200に対して直列になる位置まで水平回転させているが、奥側の縦梁200を、手前側の縦梁200の図中右側に折り畳んだ状態から手前側の縦梁200に対して直列になる位置まで水平回転させるようにしてもよい。 In the present embodiment, as shown in FIG. 18, the vertical beam 200 on the back side is arranged in series with the vertical beam 200 on the front side from a state in which the vertical beam 200 on the front side is folded to the left in the drawing. The vertical beam 200 on the back side is horizontally rotated to a position where it is in series with the vertical beam 200 on the front side from the state where the vertical beam 200 on the front side is folded to the right side in the drawing. You may do so.

その場合には、第一回転片702に形成された梁本体5側から見て左側の連結孔702aと、第二回転片802に形成された梁本体5側から見て右側の連結孔802aに第一連結ピンP4を挿入して、奥側の縦梁200を手前側の縦梁200に対して水平方向に回転自在に連結し、第一回転片702に形成された梁本体5側から見て右側の連結孔702aと、第二回転片802に形成された梁本体5側から見て右左の連結孔802aに第二連結ピンP5を挿入して、奥側の縦梁200を手前側の縦梁200に対して回転不能に固定すればよい。 In that case, the connecting hole 702a formed in the first rotating piece 702 on the left side when viewed from the beam body 5 side and the connecting hole 802a on the right side when viewed from the beam body 5 side formed in the second rotating piece 802 By inserting the first connecting pin P4, the longitudinal beam 200 on the back side is horizontally rotatably connected to the longitudinal beam 200 on the front side. Then, the second connecting pin P5 is inserted into the connecting hole 702a on the right side and the connecting hole 802a formed in the second rotating piece 802 on the right and left sides as viewed from the beam main body 5 side, and the vertical beam 200 on the far side is connected to the longitudinal beam 200 on the front side. It may be fixed to the longitudinal beam 200 so as not to rotate.

このように、本実施の形態では、回転連結装置は、横向き姿勢の第一回転片702及び第二回転片802を上下に重ねた状態で上下に対向する一対の連結孔702a,802aのうちの一方の連結孔702a,802aに挿入される第一連結ピンP4で構成されており、回り止め装置は、横向き姿勢の第一回転片702及び第二回転片802を上下に重ねた状態で上下に対向する一対の連結孔702a,802aのうちの他方の連結孔702a,802aに挿入される第二連結ピンP5で構成されている。 As described above, in the present embodiment, the rotary coupling device is configured such that the first rotary piece 702 and the second rotary piece 802 in the lateral posture are stacked one on top of the other, and one of the pair of coupling holes 702a, 802a that face each other vertically.

また、上記手順によると、奥側の縦梁200を、吊り足場装置100の幅方向に沿わせた状態で、手前側の縦梁200に対して水平方向に回転自在に連結できる。すると、奥側の縦梁200の両端は奥行方向で手前側に位置するため、奥側の縦梁200を手前側の縦梁200に連結する作業を、既に組み上げられた足場ユニットA1上で、2人の作業者が縦梁200を保持しながら行うことができる。よって、奥行方向で隣り合う縦梁200,200同士を連結する作業を安全に行うことができる。 Further, according to the above procedure, the vertical beam 200 on the back side can be horizontally rotatably connected to the vertical beam 200 on the front side in a state of being aligned with the width direction of the suspended scaffolding device 100 . Then, since both ends of the back side vertical beam 200 are located on the front side in the depth direction, the work of connecting the back side vertical beam 200 to the front side vertical beam 200 is performed on the already assembled scaffolding unit A1. Two workers can do this while holding the longitudinal beam 200 . Therefore, the operation of connecting the vertical beams 200, 200 adjacent in the depth direction can be safely performed.

また、本実施の形態では、第一回転片702に設けられた一対の連結孔702a,702aと第二回転片802に設けられた一対の連結孔802a,802aが、それぞれ奥行方向から見て横方向に並べて配置されているため、奥側の縦梁200を手前側の縦梁200に連結する際に、第一回転片702に設けられた一対の連結孔702a,702aと第二回転片802に設けられた一対の連結孔802a,802aが縦方向に並べて配置される場合と比較して、連結孔702a,802aの位置が手前側に近くなる。そのため、各連結孔702a,802aに第一連結ピンP4及び第二連結ピンP5を挿入する際に、作業者が足場ユニットA1上から身を乗りだす量を少なくできる。 In addition, in the present embodiment, the pair of connecting holes 702a, 702a provided in the first rotating piece 702 and the pair of connecting holes 802a, 802a provided in the second rotating piece 802 are arranged horizontally when viewed from the depth direction. Since they are arranged side by side in the direction, when connecting the vertical beam 200 on the back side to the vertical beam 200 on the front side, the pair of connecting holes 702 a provided in the first rotating piece 702 and the second rotating piece 802 The positions of the connecting holes 702a, 802a are closer to the front side than in the case where the pair of connecting holes 802a, 802a provided in the front side are arranged side by side in the vertical direction. Therefore, when inserting the first connecting pin P4 and the second connecting pin P5 into the respective connecting holes 702a, 802a, the amount of the operator leaning over the scaffolding unit A1 can be reduced.

さらに、本実施の形態では、第一回転片702の長辺の幅方向中央を通る中心線を挟んで配置されている一対の連結孔702a,702aと第二回転片802の長辺の幅方向中央を通る中心線を挟んで配置されている一対の連結孔802a,802aに第一連結ピンP4と第二連結ピンP5を挿入して、第一回転片702と第二回転片802とが連結されているので、奥行方向で隣り合う縦梁200,200同士の横振れを防止できる。 Furthermore, in the present embodiment, a pair of connecting holes 702a, 702a arranged across the center line passing through the center of the width direction of the long side of the first rotary piece 702 and the width direction of the long side of the second rotary piece 802 are arranged. A first connecting pin P4 and a second connecting pin P5 are inserted into a pair of connecting holes 802a, 802a arranged to sandwich the center line passing through the center, and the first rotating piece 702 and the second rotating piece 802 are connected.

Furthermore, the first rotating piece 702 and the second rotating piece 802 each have a pair of connecting holes 702a, 702a (802a, 802a) arranged across the center line passing through the center of the width direction of the long side. , The rotary connecting device is a pair of vertically facing connecting holes 702a, 702a (802a, 802a) in a state in which the first rotating piece 702 and the second rotating piece 802 in a lateral posture are stacked vertically. 702a, 802a having a first connecting pin P4 to be inserted into the anti-rotation device, the anti-rotation device has a pair of connecting holes vertically facing each other in a state in which the first rotating piece 702 and the second rotating piece 802 in a sideways posture are stacked vertically. It has a second connecting pin P5 inserted into the other connecting hole 702a, 802a of 702a, 702a (802a, 802a).

この構成によると、吊り足場装置100の組立時において、奥側の縦梁200を、吊り足場装置100の幅方向に沿わせた状態で、手前側の縦梁200に対して回転自在に連結できるので、2人の作業者で奥側の縦梁200を保持しながら、奥側の縦梁200を手前側の縦梁200に連結する作業を行うことができる。よって、奥行方向で隣り合う縦梁200,200同士の連結作業を安全に行うことができる。 According to this configuration, when the suspended scaffolding device 100 is assembled, the longitudinal beams 200 on the far side can be rotatably connected to the longitudinal beams 200 on the front side while being aligned along the width direction of the suspended scaffolding device 100. Therefore, two workers can connect the back vertical beam 200 to the front vertical beam 200 while holding the back vertical beam 200 . Therefore, the work of connecting the vertical beams 200, 200 adjacent in the depth direction can be safely performed.

Therefore, when inserting the first connecting pin P4 and the second connecting pin P5 into the respective connecting holes 702a, 802a, the amount of the operator leaning over the scaffolding unit A1 can be reduced.

さらに、上記構成によると、第一回転片702の長辺の幅方向中央を通る中心線を挟んで配置されている一対の連結孔702a,702aと第二回転片802の長辺の幅方向中央を通る中心線を挟んで配置されている一対の連結孔802a,802aに第一連結ピンP4と第二連結ピンP5を挿入して、第一回転片702と第二回転片802とが連結されているので、奥行方向で隣り合う縦梁200,200同士の横振れを防止できる。 Furthermore, according to the above configuration, the pair of connecting holes 702a, 702a arranged across the center line passing through the widthwise center of the long side of the first rotating piece 702 and the widthwise center of the long side of the second rotating piece 802 A first connecting pin P4 and a second connecting pin P5 are inserted into a pair of connecting holes 802a and 802a that are arranged across the center line passing through to connect the first rotating piece 702 and the second rotating piece 802.

この構成によると、第一回転片702の連結孔702aと第二回転片802の連結孔802aを上下に対向させる際に、第二回転片802の回転軸である第二軸部材S2が挿入される保持筒804と、第一回転片702の回転軸である第一軸部材S1とを、各収容溝702b,802bにそれぞれ収容できる。 According to this configuration, when the connecting hole 702a of the first rotating piece 702 and the connecting hole 802a of the second rotating piece 802 face each other vertically, the second shaft member S2, which is the rotating shaft of the second rotating piece 802, is inserted. The holding cylinder 804 and the first shaft member S1, which is the rotating shaft of the first rotating piece 702, can be accommodated in the accommodating grooves 702b, 802b, respectively.

すると、収容溝702b,802bの深さ分だけ第一回転片702と第二回転片802が重なる面積を大きくできるので、縦梁200の保管や運搬を容易にするために各回転片702,802の短辺を短くしても、回転片702,802同士の連結強度を十分に確保できる。 As a result, the overlapping area of the first rotating piece 702 and the second rotating piece 802 can be increased by the depth of the accommodation grooves 702b, 802b. Even if the short sides of the rotatable pieces 702 and 802 are shortened, sufficient connection strength between the rotating pieces 702 and 802 can be ensured.

なお、本実施の形態では、一対の第二回転片802,802間に一対の第一回転片702,702が嵌合されているので、第一回転片702の第一軸部材S1が第二回転片802の収容溝802bに収容され、第二回転片802の第二軸部材S2が回転自在に挿入される保持筒804が第一回転片702の収容溝702bに収容されているが、一対の第一回転片702,702間に一対の第二回転片802,802が嵌合される場合には、第一回転片702の第一軸部材S1が回転自在に挿入される保持筒704を第二回転片802の収容溝802bに収容し、第二回転片802の第二軸部材S2を第一回転片702の収容溝702bに収容すればよい。つまり、各収容溝702b,802bの大きさは、第一回転片702の連結孔702aと第二回転片802の連結孔802aとを上下に対向させる際に、水平方向で対向する部材の大きさに合わせて適宜設定されればよい。 In the present embodiment, since the pair of first rotating pieces 702, 702 are fitted between the pair of second rotating pieces 802, 802, the first shaft member S1 of the first rotating piece 702 is the second A holding cylinder 804, which is housed in the housing groove 802b of the rotating piece 802 and into which the second shaft member S2 of the second rotating piece 802 is rotatably inserted, is housed in the housing groove 702b of the first rotating piece 702.
