Description

本発明は、高所作業に用いられる足場構造体に関する。特に、組立・分解が容易であり、作業員の昇降が容易である高所作業用足場構造体に関する。   The present invention relates to a scaffold structure used for high-altitude work. In particular, the present invention relates to a scaffolding structure for working at heights, which can be easily assembled and disassembled and can be easily moved up and down.

様々な高所作業現場において、作業に先立って高所作業用足場を築く必要があり、また、作業終了後に高所作業用足場を撤去する必要がある。この高所作業用足場の組立・分解は大変な労力と時間を要するものであり作業全体の中で大きな負担となっている。
ここで、たとえ高所作業そのものが簡単で時間のかからないものであってもこの高所作業用足場の組立・分解の労力と時間が多大な負担となっている場合もある。例えば、最近の住宅は、住居者の開放感ニーズに応じて、吹き抜けを備えることがある。吹き抜けの存在により空間に広がりが生まれ、さらに吹き抜けに大きな窓がはめられることで太陽の光が広く屋内に差し込むため、部屋が明るくなる。しかし、このような吹き抜けは天井が高く、窓や窓の桟の掃除をする場合、脚立等では手が届かない場合が多い。また吹き抜け天井の電球の交換や照明器具の掃除も困難である。このような場合にも、高所作業用足場を組んで作業を行う必要がある。 In various aerial work sites, it is necessary to build a scaffold for aerial work prior to work, and it is necessary to remove the scaffold for aerial work after completion of the work. Assembling and disassembling the scaffold for working at high places requires a lot of labor and time, and is a heavy burden in the whole work.
Here, even if the high-altitude work itself is simple and time-consuming, the labor and time for assembling / disassembling the high-altitude work scaffold may be a great burden. For example, recent homes may have a colonnade depending on the resident's sense of openness. The presence of the atrium creates a wider space, and a large window is fitted in the atrium, so that the sun is widely inserted indoors, thus brightening the room. However, such an atrium has a high ceiling, and when cleaning windows and window bars, it is often difficult to reach with a stepladder. It is also difficult to replace the ceiling light bulbs and clean the lighting fixtures. Even in such a case, it is necessary to work by using a scaffold for working at high places.

従来技術において、高所作業用足場として、一般には、図６のように組まれた足場１がある。図６に示すように、足場１は、作業台２と作業台２を支持する支持部材３により組み立てられ、筋交い６、水平筋交い７により補強された構造となっている。構造は単純であるが、各々の部材を組み上げて行かねばならず、結構な労力と時間を要するものとなっている。   In the prior art, there is generally a scaffold 1 assembled as shown in FIG. As shown in FIG. 6, the scaffold 1 is assembled by a work table 2 and a support member 3 that supports the work table 2, and has a structure reinforced by a brace 6 and a horizontal brace 7. Although the structure is simple, each member has to be assembled and requires considerable labor and time.

従来技術において、高所作業用足場１の組立・分解に要する労力と時間を低減することを図ったものとして特許文献１に開示された高所作業用足場が知られている。特許文献１に開示された高所作業用足場は、支持部材の脚を頂部枠体のレールに沿って移動させる方式で伸縮させることにより足場台の組み立て・折り畳みが行えるようにしたものであり、組立・折り畳みの作業工程の容易化を図ったものが開示されている。   In the prior art, an aerial work platform disclosed in Patent Document 1 is known as an attempt to reduce labor and time required for assembling and disassembling the aerial work platform 1. The height work scaffold disclosed in Patent Document 1 is designed to be able to assemble and fold the scaffold base by expanding and contracting by the method of moving the legs of the support member along the rails of the top frame, An assembly / folding process that is simplified is disclosed.

特開２００１−９０３３７号公報JP 2001-90337 A

図６に示すような一般的な足場は、構造は単純であるが、一つ一つの部材を組み上げて行かねばならず、結構な労力と時間を要するものとなっている。作業に際して作業員は作業台２に昇降する際に支持部材３の外壁側から昇降する構造となっているため、作業員の荷重によって足場１全体が傾かないように保持部材５による補強が必要とされる。このように、足場１本体の組立・分解および保持部材５の組立・分解には労力と時間を要するものとなっている。さらに、作業員が支持部材３の外壁側から昇降する際の重心の安定を図るために足場１全体を重い部材で形成する必要がある。
一般には、このような従来の高所作業用足場の組立・分解には２人以上の作業員が協働しながら行う必要があり、作業コストも大きなものとなっている。 A general scaffold as shown in FIG. 6 has a simple structure, but each member must be assembled and requires a lot of labor and time. When working, the worker moves up and down from the outer wall side of the support member 3 when moving up and down to the work table 2, and therefore the reinforcement by the holding member 5 is necessary so that the entire scaffold 1 does not tilt due to the load of the worker. Is done. Thus, labor and time are required for assembling / disassembling the scaffold 1 main body and assembling / disassembling the holding member 5. Furthermore, in order to stabilize the center of gravity when the worker ascends and descends from the outer wall side of the support member 3, the entire scaffold 1 needs to be formed of a heavy member.
In general, it is necessary for two or more workers to cooperate in assembling and disassembling such a conventional work platform for high places, and the work cost is also high.

特許文献１の発明に係る折り畳み式足場台は、図６に示すような一般的な足場に比べて組立・分解作業が比較的少なくて済み、労力と時間の低減を図ることができるものとなっている。しかし、一人の作業員で左右の支持部材の脚を左右同時均等に頂部枠体のレールに沿って移動させることは難しいため、一人の作業員で組立を行う場合は、左右の支部部材の脚を各々伸ばした後に作業台を取り付けざるを得ない。一人の作業員によって作業台を高所に取り付ける作業は難しくかつ落下の危険もある。２人の作業員であれば、２人が協働して左右の支持部材の脚を左右同時均等に頂部枠体のレールに沿って移動させることができるので、作業台を低所で取り付けたまま左右の支持部材の脚を伸ばして行くことができるが、やはり２人の作業員が必要となるために、依然作業コストは大きなものであった。   The folding scaffold base according to the invention of Patent Document 1 requires relatively little assembly / disassembly work compared to a general scaffold as shown in FIG. 6, and can reduce labor and time. ing. However, since it is difficult for one worker to move the left and right support member legs along the rails of the top frame at the same time, it is difficult for one worker to assemble the left and right support member legs. A work table must be attached after extending each. It is difficult for one worker to attach the work table to a high place, and there is a risk of dropping. If two workers are working together, the legs of the left and right support members can be moved simultaneously along the rails of the top frame evenly on the left and right, so the work table is attached at a low place. The legs of the left and right support members can be extended as they are, but the work cost is still large because two workers are still required.

本発明は、安全かつ容易に組立・分解することができる高所作業用足場構造体を提供することを目的とする。   An object of the present invention is to provide a scaffolding structure for working at heights that can be assembled and disassembled safely and easily.

上記課題を解決するために、本発明にかかる高所作業用足場構造体は、以下の構成を備える。なお、以下に記載の構成要素は、可能な限り任意の組み合わせが可能であり、本発明の態様または技術的特徴は以下に記載のものに限定されることなく、明細書全体および図面に記載され、或いはそれらの記載から当業者が把握することの出来る発明思想に基づいて認識されるものであることが理解されるべきである。   In order to solve the above-mentioned problem, a scaffolding structure for working at height according to the present invention has the following configuration. Note that the constituent elements described below can be arbitrarily combined as much as possible, and the aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings. It should be understood that the present invention is recognized based on the inventive concept that can be understood by those skilled in the art from the description.

本発明の高所作業用足場構造体は、間隔を隔てて平行に配置された一対の支持部材と、前記支持部材に搭載される作業台とを備える高所作業用足場構造体であって、前記支持部材は、伸縮可能で高さが可変である管状縦部材と前記管状縦部材の間に配置された複数の横桟を備え、前記作業台は、天板と前記天板を前記横桟に係止するためのアーム部材を備え、前記作業台を一対の前記支持部材の任意の高さの前記横桟の間に掛け渡した状態で高さが可変である高所作業用足場構造体である。
支持部材が伸縮可能となる構造の例としては、例えば、支持部材が、前記横残一段分の高さの基本部材を摺動可能に縦方向に複数個連結した構造であり、前記基本部材が、中空の一対の支柱部材と、双方の前記支柱部材の上端部間に設けられた横桟部とからなり、順次前記支柱部材の太さを異ならせて形成し、前記支柱部材の最も太い基本部材の前記支柱部材に、順次前記支柱部材の細い前記基本部材を摺動可能に上方から嵌入させ、前記各基本部材の横桟部が順次当接した短縮状態と前記各基本部材の横桟部が適当に離れ前記支柱部材が嵌合している伸長状態とに変更可能に形成し、前記基本部材の前記横桟部に前記伸長状態を保持する伸長係止手段を設けたものがある。 The high-altitude work scaffold structure of the present invention is a high-altitude work scaffold structure comprising a pair of support members arranged in parallel at a distance, and a work table mounted on the support member, The support member includes a tubular vertical member that is extendable and variable in height, and a plurality of horizontal bars disposed between the tubular vertical members, and the work table includes the top plate and the top plate. A scaffolding structure for working at height, which is variable in height in a state in which the work table is spanned between the horizontal rails at an arbitrary height of the pair of support members. It is.
As an example of a structure in which the support member can be expanded and contracted, for example, the support member is a structure in which a plurality of basic members having a height corresponding to one horizontal step are slidably connected in the vertical direction, and the basic member is A pair of hollow strut members and a crosspiece provided between the upper end portions of both strut members, formed by sequentially varying the thickness of the strut members, and the thickest basic of the strut members The thin base member of the column member is sequentially slidably fitted into the column member of the member from above, and the horizontal beam portions of the basic members are in contact with each other in a shortened state and the horizontal beam portions of the basic members. However, it is possible to change to an extended state in which the strut members are fitted to each other appropriately, and an extension locking means for holding the extended state is provided in the lateral cross section of the basic member.

上記構成により、本発明の高所作業用足場構造体では組立・分解の作業が容易になる。例えば、支持部材を縮めた状態で２つ並べ、高さが低い状態にて先に作業台を所望の横桟に載せておく。その後、作業台を横桟に載せ置いたまま両側の支持部材を順々に伸長させてゆくことにより、作業台を所望の高さまで持ち上げることにより高所作業用足場構造体を組み上げる。この作業であれば１人の作業員であっても容易に組立・分解の作業を行うことができる。   With the above configuration, the assembling / disassembling work is facilitated in the scaffolding structure for aerial work according to the present invention. For example, two support members are arranged in a contracted state, and a work table is first placed on a desired horizontal rail in a low height state. After that, the platform work scaffolding structure is assembled by lifting the work table to a desired height by sequentially extending the supporting members on both sides while the work table is placed on the horizontal rail. With this work, even one worker can easily perform assembly and disassembly work.

ここで、上記構成において、アーム部材が横桟方向に摺動伸縮する摺動機構を備えることが好ましい。アーム部材が横桟方向に摺動伸縮する摺動機構を備えることにより、組立または分解の過程において、支持部材の一方が短縮状態と伸長状態のいずれかに変化して作業台のアーム部材が係止している横残間の距離が変化しても摺動機構の伸縮により追随可能となる。
つまり、１人の作業者のみで支持部材を左右交互に伸縮させてゆき、作業台を係止させている横桟の左右の高さが異なり斜めになったとしても、アーム部材が動的に長さを伸縮させて対応できるため、作業台を低所で載せ置いてその後徐々に支持部材を左右交互に伸ばして上昇させることができる。また分解時は逆に作業台を載せ置いた状態のまま徐々に支持部材を左右交互に縮めて下降させることができる。このように１人の作業員のみでも容易に組立・分解させることができるため、作業コストを低減することができる。 Here, in the said structure, it is preferable to provide the sliding mechanism in which an arm member slides and expands / contracts in a cross rail direction. By providing a sliding mechanism in which the arm member slides and expands in the horizontal beam direction, one of the support members changes to either the shortened state or the extended state during the assembly or disassembly process, and the arm member of the work table is engaged. Even if the distance between the remaining horizontal rests changes, it can be followed by the expansion and contraction of the sliding mechanism.
In other words, even if only one operator extends and retracts the support member alternately left and right, even if the left and right heights of the horizontal rail that locks the work table are different and slant, the arm member will dynamically Since the length can be expanded and contracted, the work table can be placed at a low place, and then the support member can be gradually extended to the left and right to be raised. On the contrary, when disassembling, the support member can be gradually contracted and lowered alternately while the work table is placed. Thus, since only one worker can be easily assembled and disassembled, the work cost can be reduced.

ここで、上記構成において、前記作業台の天板の一部にハッチを設けることが好ましい。
開閉ハッチは開状態にて作業員が天板を通過する開口となり、閉状態で作業台の一部となる。このようにハッチを設けることにより、作業員が昇降する際に、頭上の天板があっても開閉ハッチを介して通過することができるため、作業員は天板の開閉ハッチに向かって支持部材の内側から横桟を使って昇降、つまり、足場の中側から昇降することができ、重心が偏ることなく安全に昇降できる。また、作業員の昇降時において重心の偏りがないため、各部材を軽量化することができる。 Here, in the above configuration, it is preferable to provide a hatch on a part of the top plate of the work table.
The open / close hatch is an opening through which the worker passes through the top plate in the open state, and becomes a part of the work table in the closed state. By providing the hatch in this way, when the worker moves up and down, even if there is an overhead top plate, the worker can pass through the open / close hatch, so the worker can support the head member toward the open / close hatch of the top plate. It can be lifted and lowered from the inside of the scaffold using the cross rail, that is, it can be lifted and lowered safely from the inside of the scaffold without biasing the center of gravity. In addition, since the center of gravity is not biased when the worker moves up and down, each member can be reduced in weight.

なお、前記支持部材が脚高さ調整機構を備えたものであることが好ましい。
上記構成により、設置場所に段差があったとしても、脚高さ調整機構により当該段差を吸収させることができ、作業台を略水平に保つことができる。 In addition, it is preferable that the said support member is provided with the leg height adjustment mechanism.
Even if there exists a level | step difference in an installation place by the said structure, the level | step difference can be absorbed with a leg height adjustment mechanism, and a work bench | platform can be kept substantially horizontal.

さらに、上記構成において、高所作業用足場構造体を隣接させて複数台並べた状態において支持部材同士または作業台同士を相互に連結する連結部材を備えることが好ましい。
このように連結部材を用いて高所作業用足場構造体を横方向に並べた状態や縦方向に並べた状態で安定して組み上げることができ、作業台スペースを横方向または縦方向に増加させることができる。例えば、作業の範囲の長さが広い壁面設備に対する作業や、作業範囲の面積が広い天井設備に対する作業などに対する作業効率を向上させることができる。 Furthermore, in the said structure, it is preferable to provide the connecting member which mutually connects support members or work benches in the state which arranged the scaffold structure for high-altitude work adjacently.
In this way, it is possible to stably assemble the scaffolding structures for working at heights in a state in which they are arranged in the horizontal direction or in a state in which they are arranged in the vertical direction using the connecting member, and the work space is increased in the horizontal direction or the vertical direction. be able to. For example, it is possible to improve work efficiency for work on wall equipment having a wide work range, work on ceiling equipment having a wide work range, and the like.

本発明の高所作業用足場構造体によれば、組立・分解の作業が容易であり、１人の作業員であっても容易に組立・分解の作業を行うことができる。例えば、支持部材を縮めた状態で２つ並べ、高さが低い状態にて先に作業台を所望の横桟に載せておき、その後、作業台を横桟に載せ置いたまま両側の支持部材を順々に伸長させてゆくことにより、作業台を所望の高さまで持ち上げることにより高所作業用足場構造体を組み上げることができる。   According to the scaffold work structure for high place work of the present invention, assembly / disassembly work is easy, and even one worker can easily perform assembly / disassembly work. For example, two support members are arranged side by side in a contracted state, and a work table is placed on a desired horizontal beam in a state where the height is low, and then the support members on both sides while the work table is placed on the horizontal beam. By elongating the steps one after another, it is possible to assemble a scaffold structure for working at a high place by lifting the work table to a desired height.

The present invention is not limited to the embodiment shown below.

実施例１にかかる本発明の高所作業用足場構造体１００の構成例について説明する。
図１は、本発明の実施例１に係る高所作業用足場構造体１００を模式的に示す斜視図である。図１に示すように、高所作業用足場構造体１００は、一対の支持部材３０と、支持部材３０に搭載される作業台２０などの部材により組み立てられている。なお、ここでは、補強部材として筋交い６０や水平筋交い６１等の補強部材を備えた構成例となっている。 The structural example of the scaffold work structure 100 for high place work of this invention concerning Example 1 is demonstrated.
FIG. 1 is a perspective view schematically illustrating a scaffold work structure 100 for working at heights according to a first embodiment of the present invention. As shown in FIG. 1, the aerial work scaffold structure 100 is assembled by a pair of support members 30 and members such as a work table 20 mounted on the support members 30. Here, the configuration example includes reinforcing members such as the brace 60 and the horizontal bracing 61 as the reinforcing member.

まず、支持部材３０について説明する。
支持部材３０は、伸縮可能で高さが可変である管状縦部材３１と、管状縦部材３１の間に設けられた複数の横桟３２とを備えたものとなっている。他方の支持部材も同様に、伸縮可能で高さが可変である管状縦部材３１と、管状縦部材３１の間に設けられた複数の横桟３２とを備えたものとなっている。 First, the support member 30 will be described.
The support member 30 includes a tubular vertical member 31 that is extendable and variable in height and a plurality of horizontal bars 32 provided between the tubular vertical members 31. Similarly, the other support member is provided with a tubular vertical member 31 that is extendable and variable in height, and a plurality of horizontal bars 32 provided between the tubular vertical members 31.

管状縦部材３１は全体の骨組みにおける柱のような働きをするものである。なお、作業現場への運び込みや撤去の際には管状縦部材３１を短く縮小させた状態としておく。
管状縦部材３１の素材としては、全体の重量を軽量化するために必要な構造的強度を確保せしめた上でアルミ材などを用いることが好ましい。 The tubular vertical member 31 functions like a column in the entire framework. It should be noted that the tubular vertical member 31 is shortened and shortened when being carried to the work site or removed.
As a material of the tubular vertical member 31, it is preferable to use an aluminum material or the like after ensuring the structural strength necessary to reduce the overall weight.

次に、横桟３２は、一対の管状縦部材３１の間に渡された踏み桟であり、作業者が足を掛けて昇降する部材である。横桟３２の幅としては、この例では後述する作業台の幅に対応する幅となっている。作業台の幅は作業性を考慮した大きさが必要であり、それに対応した横桟３２の幅となる。
横桟３２の高さ方向の間隔は作業者が安全に足を運ぶできることができる距離とすることが好ましい。横桟３２の段数としては特に限定されず、作業員が登る高さに応じて段数を確保する必要がある。
横桟３２の素材としては、全体の重量を軽量化するために必要な構造的強度を確保せしめた上でアルミ材などを用いることが好ましい。 Next, the horizontal rail 32 is a step rail passed between the pair of tubular vertical members 31 and is a member that is lifted and lowered by an operator. The width of the horizontal rail 32 is a width corresponding to the width of a work table described later in this example. The width of the work table needs to be large in consideration of workability, and corresponds to the width of the horizontal rail 32 corresponding thereto.
The distance in the height direction of the crosspieces 32 is preferably set to a distance that allows an operator to safely move his / her foot. The number of steps of the horizontal rail 32 is not particularly limited, and it is necessary to secure the number of steps according to the height of the worker climbing.
As a material for the horizontal rail 32, it is preferable to use an aluminum material or the like after ensuring the structural strength necessary to reduce the overall weight.

次に、支持部材３０の伸縮機能について図２を参照しつつ詳述する。
図２は、支持部材３０のみを取り出して示した図である。図２（ａ）は短縮状態、図２（ｂ）は伸長途中状態の一例を示す図、図２（ｃ）は伸長状態を示す図である。
なお、支持部材３０の基本部材の段数、横桟３２の段数などは一例であり、特に限定されないことは言うまでもない。 Next, the telescopic function of the support member 30 will be described in detail with reference to FIG.
FIG. 2 is a view showing only the support member 30 taken out. 2A is a diagram showing an example of a shortened state, FIG. 2B is a diagram showing an example of a stretched state, and FIG. 2C is a diagram showing a stretched state.
Needless to say, the number of steps of the basic member of the support member 30 and the number of steps of the cross rail 32 are examples, and are not particularly limited.

この構成例では、支持部材３０は、複数の基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇ、３０ｈから構成された例となっている。   In this configuration example, the support member 30 is an example configured from a plurality of basic members 30a, 30b, 30c, 30d, 30e, 30f, 30g, and 30h.

図２に示すとおり、支持部材３０の基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇ、３０ｈは、間隔を隔てて平行に配置され両側で対をなす管状縦部材３１ａ、３１ｂ、３１ｃ、３１ｄ、３１ｅ、３１ｆ、３１ｇ、３１ｈと、その双方の管状縦部材の上端間に設けられた横桟３２ａ、３２ｂ、３２ｃ、３２ｄ、３２ｅ、３２ｆ、３２ｇ、３２ｈを備えた構造となっている。   As shown in FIG. 2, the basic members 30a, 30b, 30c, 30d, 30e, 30f, 30g, and 30h of the support member 30 are arranged in parallel with a gap therebetween and are formed in pairs on both sides. , 31d, 31e, 31f, 31g, 31h, and horizontal bars 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h provided between the upper ends of both of the tubular vertical members. .

この構成例では、複数の基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇ、３０ｈは、管状縦部材の太さを順次異ならせて形成し、管状縦部材の最も太い基本部材３０ｈの双方に、順次管状縦部材の細くなった基本部材３０ｇ、３０ｆ、３０ｅ、３０ｄ、３０ｂ、３０ｃ、３０ａを摺動可能に上方から嵌入させ、横桟が順次上下に当接するものとなっている。基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇを順次上方に摺動することにより、支持部材３０は伸縮し、作業に必要な高さを得ることができるものとなっている。   In this configuration example, the plurality of basic members 30a, 30b, 30c, 30d, 30e, 30f, 30g, and 30h are formed by sequentially changing the thickness of the tubular vertical member, and the thickest basic member 30h of the tubular vertical member is formed. In both sides, the basic members 30g, 30f, 30e, 30d, 30b, 30c, and 30a, which are successively thinned tubular vertical members, are slidably fitted from above, and the horizontal rails are sequentially brought into contact with each other in the vertical direction. By sliding the basic members 30a, 30b, 30c, 30d, 30e, 30f, and 30g sequentially upward, the support member 30 expands and contracts, and the height required for the work can be obtained.

図２（ｂ）に示す支持部材３０の伸長の途中状態の例では、上段から順に、上にある基本部材３０ａ、３０ｂ、３０ｃ、３０ｄがそれぞれ直下段の基本部材３０ｂ、３０ｃ、３０ｄ、３０ｅに対して上方向に摺動して所定距離となったところで各々係止固定した状態となっている。   In the example in the middle of extension of the support member 30 shown in FIG. 2B, the upper basic members 30a, 30b, 30c, and 30d are changed from the upper stage to the basic members 30b, 30c, 30d, and 30e, respectively, immediately below. On the other hand, each of them is locked and fixed at a predetermined distance after sliding upward.

係止手段は、各基本部材の伸張状態を保持するものであり、解除操作手段は、係止手段の作用状態を解除するものである。
係止手段は、基本部材の管状縦部材３１の摺動をとめて固定できるストッパーであれば特に限定されないが、例えば、基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇの各横桟の内部に設けられている。この構成例では、係止手段は、例えば、小円柱状の突出部材（図示せず）が横桟３２の内部において略水平に仕込まれており、コイルばねからなる付勢手段（図示せず）により外側、つまり、管状縦部材３１方向に突出できるように付勢されたものとなっている。この小円柱状の突出部材を直上の基本部材の管状縦部材３１に突きたてることにより、直上の基本部材３０を固定する。 The locking means holds the extended state of each basic member, and the release operation means releases the operating state of the locking means.
The locking means is not particularly limited as long as it is a stopper that can be fixed by stopping sliding of the tubular vertical member 31 of the basic member. For example, each of the horizontal rails of the basic members 30a, 30b, 30c, 30d, 30e, 30f, and 30g is used. Is provided inside. In this configuration example, the locking means includes, for example, a small columnar projecting member (not shown) that is loaded substantially horizontally inside the horizontal rail 32, and an urging means (not shown) made of a coil spring. Therefore, it is biased so that it can protrude outward, that is, in the direction of the tubular vertical member 31. The basic member 30 directly above is fixed by striking the small columnar protruding member against the tubular vertical member 31 of the basic member directly above.

一方、各々の管状縦部材３１には、上端の横桟３２の高さから所定距離下方の位置に小孔（図示せず）が設けられている。管状縦部材３１が摺動して直下の基本部材に対して上方へ移動する際、直下の基本部材の係止手段は、移動中は管状縦部材３１の壁面が当接して押さえられており、コイルばねの付勢によっても突出できない状態であるが、管状縦部材３１が摺動しつつ上昇して小孔が小円柱状の突出部材の真横に到達すると、コイルばねの付勢により小円柱状の突出部材が小孔内に突き刺さり、管状縦部材３１が固定される仕組みとなっている。   On the other hand, each tubular vertical member 31 is provided with a small hole (not shown) at a position below a predetermined distance from the height of the horizontal rail 32 at the upper end. When the tubular vertical member 31 slides and moves upward with respect to the basic member directly below, the locking means of the basic member directly below is pressed against the wall surface of the tubular vertical member 31 during movement, Although it is in a state where it cannot project even by the bias of the coil spring, when the tubular vertical member 31 rises while sliding and the small hole reaches the side of the small columnar projecting member, the small cylindrical shape is generated by the bias of the coil spring. The protruding member is inserted into the small hole and the tubular vertical member 31 is fixed.

解除操作手段は、上記係止手段を解除するものであり、係止手段に対応した解除手段であれば特に限定されない。上記例の係止手段に対応した解除操作手段は、突出部材を外部から操作できるように突出部材に設けてある操作つまみを、横桟３２に形成された長孔から突出させた構成である。この操作つまみを付勢手段に抗して操作して突出部材を内側に後退させることにより、小孔に突き刺さっている小円柱状の突出部材を引き抜き、管状縦部材３１を再び摺動自在の状態に戻す。
このように、支持部材３０は、横残３２一段分の高さの基本部材を複数個連結し、それぞれを縦方向に摺動可能な構造とすることにより、伸縮機能を備えたものとなっている。 The release operation means is for releasing the locking means, and is not particularly limited as long as it is a release means corresponding to the locking means. The release operation means corresponding to the locking means in the above example has a configuration in which an operation knob provided on the protruding member is protruded from a long hole formed in the horizontal rail 32 so that the protruding member can be operated from the outside. The operation knob is operated against the urging means to retract the protruding member inward, thereby pulling out the small columnar protruding member stuck in the small hole and allowing the tubular vertical member 31 to slide again. Return to.
As described above, the support member 30 is provided with an expansion / contraction function by connecting a plurality of basic members having a height corresponding to one step of the horizontal remaining 32 and slidably moving each of the basic members in the vertical direction. Yes.

なお、図１に示す構成例において、支持部材３０は、下端部に脚高さ調整機構５０を備えうる。例えば、床面に当接される座板にネジ部が設けられて上下方向に調整可能な機構などがある。このような高さ調整機構５０により、床面に凹凸がある場合や、階段等においても本発明の高所作業用足場構造体１００の設置が可能になる。   In the configuration example shown in FIG. 1, the support member 30 can include a leg height adjusting mechanism 50 at the lower end. For example, there is a mechanism in which a thread portion is provided on a seat plate that is in contact with the floor surface and can be adjusted in the vertical direction. Such a height adjustment mechanism 50 makes it possible to install the scaffold work structure 100 for working at high places of the present invention even when the floor surface is uneven or on stairs.

次に、作業台２０を説明する。
作業台２０は、天板２１と、天板の一部に設けられた開閉可能な開閉ハッチ２２と、天板２１および開閉ハッチ２２を支える天板支持体２３と、横桟に係止されるアーム２４を備えた構造となっている。
図３（ａ）は作業台２０の全体を示す上面図であり、図３（ｂ）はハッチ２２の閉状態を示す斜視図、図３（ｃ）はハッチ２２の開状態を示す斜視図である。 Next, the work table 20 will be described.
The work table 20 is locked to a top plate 21, an openable / closable hatch 22 provided on a part of the top plate, a top plate support 23 that supports the top plate 21 and the open / close hatch 22, and a horizontal rail. The arm 24 is provided.
3A is a top view showing the entire work table 20, FIG. 3B is a perspective view showing a closed state of the hatch 22, and FIG. 3C is a perspective view showing an open state of the hatch 22. FIG. is there.

天板２１は作業員の踏み板となるものであり、作業員の体重をしっかり支える例えばステンレス鋼板などの素材で構成されている。なお、一部に開口が設けられており、その開口の上面に対して開閉ハッチ２２が開閉可能に設けられている。   The top board 21 serves as a tread board for the worker, and is made of a material such as a stainless steel plate that firmly supports the weight of the worker. Note that an opening is provided in part, and an opening / closing hatch 22 is provided to be openable / closable with respect to the upper surface of the opening.

開閉ハッチ２２は、天板の一部に設けられた開口を覆うように設けられた部材であり、蝶番などにより開閉可能な構造となっている。なお、図３（ｂ）に示されるとおり、閉状態においては天板支持体２３により戴置され、係止されるようになっている。
開閉ハッチ２２は、後述するように、開状態では作業員が天板を通過する開口を提供することができ、閉状態では開口を覆って作業床の一部となり、天板２１と一体になり、作業員が作業床の一部として踏みしめることができるものとなる。
開閉ハッチ２２は閉状態では開口を覆って作業床の一部となるので、開閉ハッチ２２の素材は天板と同じ素材、例えば、ステンレス鋼板などの素材で構成されることが好ましい。 The opening / closing hatch 22 is a member provided so as to cover an opening provided in a part of the top plate, and has a structure that can be opened and closed by a hinge or the like. In addition, as shown in FIG. 3B, in the closed state, it is placed and locked by the top support 23.
As will be described later, the opening / closing hatch 22 can provide an opening through which the worker passes through the top plate in the open state, and covers the opening and becomes a part of the work floor in the closed state, and is integrated with the top plate 21. The worker can step on as part of the work floor.
Since the opening / closing hatch 22 covers the opening and becomes a part of the work floor in the closed state, the material of the opening / closing hatch 22 is preferably made of the same material as the top plate, such as a stainless steel plate.

開閉ハッチ２２を開状態にするには、後述するように、支持部材３０をよじ昇ってきた作業者が作業台２０の底面から開閉ハッチ２２を押し上げればよい。図３（ｃ）は、開閉ハッチ２２の開状態を示す。図３（ｃ）に構造例では、開閉ハッチ２２は、作業台２０の幅方向に開閉し、開閉方向の一端に蝶番（図に示されない）を備えた構造となっている。なお、この構成例では、開閉ハッチ２２は開閉レバー２５を備えたものとなっている。開閉レバー２５は、中間部にあるつまみをつまんで下げれば閉じる役割を果たすとともに、開閉ハッチ２２が作業台２０から落下することを防ぐ。   In order to open the open / close hatch 22, as will be described later, an operator who has lifted the support member 30 may push up the open / close hatch 22 from the bottom surface of the work table 20. FIG. 3C shows an open state of the open / close hatch 22. 3C, the opening / closing hatch 22 has a structure that opens and closes in the width direction of the work table 20, and has a hinge (not shown) at one end in the opening and closing direction. In this configuration example, the opening / closing hatch 22 includes an opening / closing lever 25. The open / close lever 25 plays a role of closing if a pin located at the intermediate part is pinched and prevents the open / close hatch 22 from dropping from the work table 20.

天板支持体２３は、天板２１の下側に位置して天板２１を支える部材である。この構成例では天板２１に対する枠体として下方から天板２１を支えるものとなっている。天板支持体２３も天板を支える構造強度が必要であるので、例えば、ステンレス材などの素材が好ましい。   The top plate support 23 is a member that is positioned below the top plate 21 and supports the top plate 21. In this configuration example, the top plate 21 is supported from below as a frame for the top plate 21. Since the top plate support 23 also needs structural strength to support the top plate, for example, a material such as stainless steel is preferable.

アーム２４は、一対の支持部材３０の任意の横桟３２に橋渡しされるように掛けられ、作業台２０全体を一対の支持部材３０の任意の横桟３２に対して係止する部材である。図３（ａ）に示されるとおり、アーム２４が横桟３２を把持することにより、作業台２０は支持部材３０に搭載される。この構成例では、アーム２４の先端部分には、横桟３２の上面から側面に対応するフック状の嵌合形状が設けられており、横桟３２の上面から側面にしっかりと嵌ることにより係止することができ、作業台２０を安定した状態で横桟３２間を橋渡しするように取り付けが可能となっている。アーム２４も天板を支える構造強度が必要であるので、例えば、ステンレス材などの素材が好ましい。   The arm 24 is a member that is hung so as to be bridged to an arbitrary horizontal beam 32 of the pair of support members 30, and locks the entire work table 20 to the arbitrary horizontal beam 32 of the pair of support members 30. As shown in FIG. 3A, the work table 20 is mounted on the support member 30 when the arm 24 grips the horizontal rail 32. In this configuration example, the tip portion of the arm 24 is provided with a hook-like fitting shape corresponding to the side surface from the upper surface of the horizontal beam 32, and is locked by firmly fitting from the upper surface of the horizontal beam 32 to the side surface. The work table 20 can be attached so as to bridge between the crosspieces 32 in a stable state. Since the arm 24 also needs structural strength to support the top plate, for example, a material such as stainless steel is preferable.

次に、作業台２０のアーム２４の伸縮機能の工夫について述べる。
上記したように、支持部材３０を伸長させて組立て、縮小して畳むことが可能であるが、本発明に係る高所作業用足場構造体１００では、作業台２０の組み上げ方に工夫が施されている。作業台２０の支持部材３０の横桟３２への取り付け作業が、作業員が地上にいる状態で行うことができれば非常に楽である。逆に、支持部材３０を所定の伸長状態に伸ばし切ってから作業員が作業台２０を持ち上げて支持部材３０の横桟３２へ取り付けることとなると非常に不便であり、かつ危険な作業となってしまう。そこで、作業員が地上にいる状態にて、支持部材３０の横桟３２へ作業台２０の取り付け作業を行い、作業台２０を支持部材３０の横桟３２へ取り付けた状態で支持部材３０を伸長して作業台２０を高く持ち上げることを可能とした。
ここで、本発明の高所作業用足場構造体１００では、かつ、作業台２０を支持部材３０の横桟３２へ取り付けた状態で容易に支持部材３０を伸長して行くことができるよう作業台のアーム２４が伸縮するよう工夫している。 Next, a device for expanding and contracting the arm 24 of the work table 20 will be described.
As described above, the support member 30 can be extended, assembled, reduced, and folded. However, in the scaffold work structure 100 for working at a high place according to the present invention, a method for assembling the work table 20 is devised. ing. It is very easy if the work of attaching the support member 30 of the work table 20 to the crosspiece 32 can be performed while the worker is on the ground. On the contrary, it is very inconvenient and dangerous when an operator lifts the work table 20 and attaches it to the crosspiece 32 of the support member 30 after the support member 30 is fully extended. End up. Therefore, the work table 20 is attached to the horizontal beam 32 of the support member 30 while the worker is on the ground, and the support member 30 is extended with the work table 20 attached to the horizontal beam 32 of the support member 30. Thus, the work table 20 can be lifted high.
Here, in the scaffold work structure 100 for high place work of the present invention, the work table can be easily extended while the work table 20 is attached to the crosspiece 32 of the support member 30. The arm 24 is designed to expand and contract.

支持部材３０は、短縮状態から、基本部材３０ａ、３０ｂ、３０ｃ、３０ｄ、３０ｅ、３０ｆ、３０ｇを順次上方に伸張することができるが、この動きに追随できるように、作業台２０のアーム２４は摺動機構を備えている。例えば、天板支持体２３とアーム２４との間にガイドレールのような摺動機構を設ければよい。   The support member 30 can extend the basic members 30a, 30b, 30c, 30d, 30e, 30f, and 30g sequentially from the shortened state, but the arm 24 of the work table 20 is configured to follow this movement. A sliding mechanism is provided. For example, a sliding mechanism such as a guide rail may be provided between the top support 23 and the arm 24.

高所作業用足場構造体１００の組み立てを図４を参照しつつ説明する。
図４は本発明の高所作業用足場構造体１００が組み立てられる状態の一部を模式的に示す図であり、図４（ａ）は上から２段目の横桟に作業台を戴置した状態を示す図であり、図４（ｂ）は一方の支持部材を一段伸張した状態を示し、図４（ｃ）はもう一方の支持部材を一段伸張した状態を示す図である。 The assembly of the aerial work scaffold structure 100 will be described with reference to FIG.
FIG. 4 is a view schematically showing a part of a state in which the scaffold work structure 100 for working at a high level according to the present invention is assembled. FIG. 4 (b) shows a state in which one support member is extended by one step, and FIG. 4 (c) shows a state in which the other support member is extended by one step.

まず、図４（ａ）に示すように、作業員が地上にいる状態で、作業台２０を横桟３２に戴置する。なお、この例では作業台２０を載せおく横桟３２は上から２段目としているが、他の段であっても良い。   First, as shown in FIG. 4A, the work table 20 is placed on the crosspiece 32 with the worker on the ground. In this example, the horizontal rail 32 on which the work table 20 is placed is the second level from the top, but may be another level.

次に、図４（ｂ）に示すように、一方の基本部材３１ｂを上方に引き延ばす。そうすると、作業台２０を載せ置いた横桟３２の高さが左右で異なるものとなり、作業台２０が斜めになりつつ、かつ、横桟３２間の距離が変動することとなる。もし、作業台２０のアーム２４に伸縮機能がなければ、このように、作業台２０を載せ置いた横桟３２の高さが左右で異なることは許容できず、左右それぞれの基本部材３１ｂを同時に上げざるを得ず、作業員が左右１人ずつ計２人必要となってしまう。しかし、この構成例では、作業台２０のアーム２４が摺動機構により図面右上方向に摺動することにより伸縮して横桟３２間の距離の変動に追随することができる仕組みとなっている。   Next, as shown in FIG. 4B, one basic member 31b is extended upward. Then, the height of the horizontal beam 32 on which the work table 20 is placed is different on the left and right, and the work table 20 is inclined and the distance between the horizontal beams 32 varies. If the arm 24 of the work table 20 does not have an extension / contraction function, the horizontal bars 32 on which the work table 20 is placed cannot be allowed to have different heights on the left and right sides. Inevitably, two workers are required, one on each side. However, in this configuration example, the arm 24 of the work table 20 can be expanded and contracted by sliding in the upper right direction of the drawing by the sliding mechanism, and can follow the variation in the distance between the horizontal bars 32.

次に、図４（ｃ）に示すように、他方の支持部材３０の基本部材３１ｂを上方に引き延ばす。そうすると、作業台２０を載せ置いた横桟３２の高さが左右で同じになり、作業台２０が略水平になり、かつ、横桟３２間の距離が元に戻ることとなる。この結果、作業台２０は床面に略平行に一段高くなる。この作業を他の基本部材についても繰り返し、左右の基本部材３１ｇをそれぞれ交互に上方に引き上げてゆけば、作業台２０が所定の作業位置にまで到達することができる。
このように、支持部材３０を伸長させ、作業台２０を所定の高さまで組み上げた後、筋交い６０や水平筋交い６１等の補強部材を取り付けて高所作業用足場構造体１００を完成させる。 Next, as shown in FIG. 4C, the basic member 31b of the other support member 30 is extended upward. Then, the height of the horizontal beam 32 on which the work table 20 is placed becomes the same on the left and right, the work table 20 becomes substantially horizontal, and the distance between the horizontal beams 32 is restored. As a result, the work table 20 is raised one step substantially parallel to the floor surface. If this operation is repeated for the other basic members and the left and right basic members 31g are alternately pulled upward, the work table 20 can reach a predetermined work position.
Thus, after extending the support member 30 and assembling the work table 20 to a predetermined height, reinforcing members such as the brace 60 and the horizontal brace 61 are attached to complete the scaffold work structure 100 for working at high places.

なお、補強部材である筋交い６０は、支持部材３０間に渡されるものであり、筋交い６０を設ける位置などは構造強度を確保できるものであれば特に限定されないが、図１の構成例では、支持部材３０間に斜めに渡されている。補強部材である水平筋交い６１も支持部材３０間に渡されるものであり、水平筋交い６１を設ける位置などは構造強度を確保できるものであれば特に限定されないが、図１の構成例では、支持部材３０間に略水平に渡されている。   In addition, the brace 60 which is a reinforcing member is passed between the support members 30, and the position where the brace 60 is provided is not particularly limited as long as the structural strength can be secured, but in the configuration example of FIG. It is passed diagonally between the members 30. The horizontal bracing 61, which is a reinforcing member, is also passed between the support members 30, and the position where the horizontal bracing 61 is provided is not particularly limited as long as the structural strength can be secured, but in the configuration example of FIG. It is passed substantially horizontally between 30.

なお、筋交い６０や水平筋交い６１を設ける箇所は、作業員が高所作業用足場構造体１００の内側へ出入し、くぐりやすいような箇所に適宜設ければよい。
筋交い６０、水平筋交い６１の素材は特に限定されないが、この例ではアルミなどのパイプ材となっている。全体の重量を軽量化するために必要な構造的強度を確保せしめるように太さや肉厚径を決めることが好ましい。 In addition, what is necessary is just to provide the location which provides the bracing 60 or the horizontal bracing 61 suitably in the location where an operator goes in and out of the scaffolding structure 100 for work in a high place, and can pass easily.
The material of the brace 60 and the horizontal brace 61 is not particularly limited, but in this example, it is a pipe material such as aluminum. It is preferable to determine the thickness and the wall thickness so as to ensure the structural strength necessary to reduce the overall weight.

次に、高所作業用足場構造体１００での作業員の昇降動作について説明する。
図５は、高所作業用足場構造体１００への作業者Ｈの昇状態を示す図であり、図５（ａ）は地面から作業者Ｈが昇り始める状態を示す斜視図、図５（ｂ）は作業者Ｈがハッチ２２を開いて作業台２０に昇る直前状態を示す斜視図である。 Next, the raising / lowering operation | movement of the worker in the scaffold work structure 100 for high place work is demonstrated.
FIG. 5 is a view showing a rising state of the worker H to the scaffolding structure 100 for working at a high place, and FIG. 5 (a) is a perspective view showing a state where the worker H starts to rise from the ground, and FIG. ) Is a perspective view showing a state immediately before the worker H opens the hatch 22 and rises to the work table 20.

図５（ａ）に示すとおり、本発明に係る高所作業用足場構造体１００は、支持部材３０の外面側から横桟３２を登って行くではなく、支持部材３０の内側から横桟３２をよじ昇ることができる。そして、作業台２０の底面まで到達すると、図５（ｂ）に示すように、頭上にある開閉ハッチ２２を開いて作業台２０に上がる構造になっている。このように、本発明に係る高所作業用足場構造体１００では作業台２０に開閉ハッチ２２を設けておくことにより、外面側から登る必要はなく、図５（ｂ）に示すように支持部材３０の内側から横桟３２をよじ昇ることができ、重心が安定しやすい。
したがって、作業者Ｈは安全に作業台２０に到達することが可能である。 As shown in FIG. 5 (a), the aerial work scaffold structure 100 according to the present invention does not climb the horizontal beam 32 from the outer surface side of the support member 30, but extends the horizontal beam 32 from the inside of the support member 30. You can climb. When reaching the bottom surface of the work table 20, as shown in FIG. 5B, the opening / closing hatch 22 located above the head is opened and the work table 20 is raised. In this way, in the aerial work scaffold structure 100 according to the present invention, by providing the opening / closing hatch 22 on the work table 20, there is no need to climb from the outer surface side, and the support member as shown in FIG. It is possible to climb up the horizontal rail 32 from the inside of 30 and the center of gravity tends to be stable.
Therefore, the worker H can safely reach the work table 20.

さらに、本発明の高所作業用足場構造体１００によれば、作業員が開閉ハッチ２２を通過後、開閉ハッチ２２を閉じれば天板支持体２３に係止されて安定し、天板２１と一体になって作業台２０の一部となるため、作業足場を広く確保する事ができ、かつ、開口から落下するなどの事故も防ぐことができる。   Further, according to the scaffold work structure 100 for high place work of the present invention, if the operator closes the open / close hatch 22 after passing through the open / close hatch 22, the work is locked and stabilized by the top plate support 23. Since it is integrated and becomes a part of the workbench 20, a wide working scaffold can be secured, and accidents such as falling from the opening can be prevented.

本発明の高所作業用足場構造体１００の基本構成を示したが、高所作業用足場構造体１００同士をさらに複数台並べて組み上げることも可能である。
例えば、高所作業用足場構造体１００を隣接させて複数台並べた状態において支持部材３０同士や作業台２０同士を連結する連結部材（図示せず）を用いて、図１に示した高所作業用足場構造体１００を横方向に２台以上並べて組み上げて作業台の横方向の長さを拡げたり、縦方向に２台以上並べて組み上げて作業台の縦方向の幅を拡げたりすることも可能である。 Although the basic configuration of the aerial work scaffold structure 100 of the present invention is shown, it is also possible to assemble a plurality of the aerial work scaffold structures 100 side by side.
For example, using a connecting member (not shown) that connects the support members 30 and the work tables 20 in a state in which a plurality of the work structures 100 are arranged adjacent to each other, the height shown in FIG. Two or more working scaffold structures 100 may be assembled side by side to increase the horizontal length of the work table, or two or more vertical work structures may be assembled to increase the vertical width of the work table. Is possible.

以上、本発明に係る高所作業用高所作業用足場構造体における好ましい実施形態を図示して詳細に説明してきたが、本発明の技術的範囲を逸脱することなく種々の変更が可能であることは理解されるであろう。   As described above, the preferred embodiments of the aerial work scaffold structure for high work according to the present invention have been illustrated and described in detail, but various modifications can be made without departing from the technical scope of the present invention. It will be understood.

本発明の高所作業用足場構造体は、屋内工事用または屋外工事用の高所作業用足場として広く利用することができる。   The aerial work scaffold structure according to the present invention can be widely used as an aerial work scaffold for indoor work or outdoor work.
