Description

本発明は、大規模であっても、簡易に折り畳み、折り畳み、展開可能な折り畳み式足場に関する。 The present invention relates to a foldable scaffold that can be easily folded, folded and deployed even on a large scale.

工事開始から終了まで、常時足場を設置することができない工事現場、例えば、道路、線路などがある。そのような工事現場では定期的に足場を組み立て、分解を必要とする。その作業は煩雑で、工期の長期化の原因になっている。 There are construction sites, such as roads and railways, where scaffolding cannot be installed at all times from the start to the end of construction. Such construction sites require regular scaffolding and disassembly. The work is complicated and causes a long construction period.

したがって、簡易に、組立て、分解が可能な足場があれば、作業者の労働付加の軽減化、工期短縮が期待できる。 Therefore, if there is a scaffold that can be easily assembled and disassembled, it can be expected that the labor load on the worker is reduced and the construction period is shortened.

そのような足場として、特許文献１などに折りたたみ式足場装置が開示されている。特許文献１の折りたたみ式足場装置は、従来に比べてよりコンパクトに折りたたむことができる折りたたみ式足場装置であって、 床板５ａ，５ｂおよび根太４を中央部で折りたたみかつ端部で横架材２に対し回転自在な構造とするものである。 As such a scaffold, a folding scaffolding device is disclosed in Patent Document 1 and the like. The foldable scaffolding device of Patent Document 1 is a foldable scaffolding device that can be folded more compactly than conventional ones, in which floor plates 5a, 5b and joists 4 are foldable at the center and lateral members 2 at the ends. It has a rotatable structure.

しかしながら、特許文献１の折りたたみ式足場装置は、折り畳み動力について開示がなく、小規模で人の手により折り畳み、展開するものである。したがって、大型、広範囲の足場には向かない。 However, the folding scaffolding device of Patent Document 1 does not disclose folding power, and is a small-scale folding and unfolding device by a human hand. Therefore, it is not suitable for large-scale, wide-range scaffolds.

以下、添付図面に基づき本発明について詳細に説明する。なお、本発明は下記実施例に限定されるものではない。 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the examples below.

本発明である折り畳み式足場１は、例えば、図１に示す線路エリア２３での利用、工事、より具体的には、擁壁２１の施工、補修において効果的である。 The folding scaffold 1 according to the present invention is effective, for example, in use and construction in the track area 23 shown in FIG. 1, more specifically in construction and repair of the retaining wall 21.

線路エリア２３では、線路２２を走行する電車に必要な空間（走行空間２４）に、足場が重なり設置され、電車の走行を阻害し、また電車の走行が工事の妨げになる。 In the track area 23, scaffolds are installed so as to overlap with the space required for the train running on the track 22 (running space 24), which obstructs the running of the train, and the running of the train interferes with the construction work.

本発明である折り畳み式足場１は、図２−４に示すように、設置位置が固定され、回動を必要としない固定支柱３と、可動支柱４と、左フレーム５及び右フレーム６と、作業員が歩行する布板７と、先端が可動支柱４の固定位置８ａに固定されるワイヤーロープ８と、駆動部９と、第一滑車１０と、第二滑車１１とからなり、収納時に使用状態から収納位置に折り畳まれ、使用時に設置位置に展開される。 As shown in FIG. 2-4, the folding scaffold 1 according to the present invention has a fixed support column 3 whose installation position is fixed and does not require rotation, a movable support column 4, a left frame 5 and a right frame 6, A cloth plate 7 on which a worker walks, a wire rope 8 whose tip is fixed to a fixed position 8a of the movable support column 4, a drive unit 9, a first pulley 10, and a second pulley 11, which are used during storage. It is folded from the state to the storage position and deployed to the installation position when used.

必要に応じて、固定支柱３と擁壁２１などを連結し、位置固定させる連結具２、作業員、工具の脱落防止のため、法規上必要とされる場合には、幅木１２、安全ネット１３、筋交い、その他に従来から足場に用いられる部品を備える。 If necessary by law, a skirting board 12 and a safety net are provided to connect the fixed support column 3 to the retaining wall 21 and fix the position, and to prevent the workers and tools from falling off, if necessary. 13. Brace and other parts conventionally used for scaffolding.

また、固定支柱３、可動支柱４は、設置場所により、ジャッキベース３ａを底部に備えるとよい。また、固定支柱３は、図２に示すように、分断されてもよい。 Further, the fixed column 3 and the movable column 4 may be provided with the jack base 3a at the bottom depending on the installation location. Further, the fixed support column 3 may be divided as shown in FIG.

なお、図３，４においては、動作、構造を理解しやすくするため、布板７、幅木１２、安全ネット１３の図示を省略した。また、図３，４中の白抜き矢印は、ワイヤーロープ８の移動方向を示している。 3 and 4, the cloth plate 7, the skirting board 12, and the safety net 13 are not shown in order to facilitate understanding of the operation and structure. The white arrows in FIGS. 3 and 4 indicate the moving direction of the wire rope 8.

可動支柱４は、折り畳み式足場を折り畳むとき上に引き上げられ、展開のとき下に降ろされる。 The movable strut 4 is pulled up when folding the folding scaffold and lowered when unfolding.

左フレーム５、右フレーム６（図２−４では、手前部品奥に隠れて視認できない）は、固定支柱３及び可動支柱４に回動可能に連結する。布板７は、左フレーム５及び右フレーム６に渡され左フレーム５及び右フレーム６とともに回動する。 The left frame 5 and the right frame 6 (in FIG. 2-4, hidden behind the front part and invisible) are rotatably connected to the fixed column 3 and the movable column 4. The cloth plate 7 is passed to the left frame 5 and the right frame 6 and rotates together with the left frame 5 and the right frame 6.

ワイヤーロープ８は、可動支柱４を設置位置から収納位置に引き上げ、また可動支柱４を収納位置から設置位置に降ろす。ここでは、ワイヤーロープ８の一端は駆動部９に接続し、他端は可動支柱４の下方の固定位置８ａに連結する。 The wire rope 8 raises the movable column 4 from the installation position to the storage position, and lowers the movable column 4 from the storage position to the installation position. Here, one end of the wire rope 8 is connected to the drive unit 9, and the other end is connected to the fixed position 8 a below the movable support column 4.

可動支柱４の収納位置が、設置位置より下方であれば、ワイヤーロープ８の巻き、送り方向は、設置位置上方の場合と収納と設置で逆向きになる（図５）。可動支柱４を設置したとき、その下方に収納スペース１５が形成されている場合には、可動支柱４の位置決めはワイヤーロープ８の張力のみでもよい。 If the storage position of the movable support column 4 is lower than the installation position, the winding and feeding directions of the wire rope 8 are opposite to those in the case above the installation position for storage and installation (FIG. 5). When the movable column 4 is installed and the storage space 15 is formed below the movable column 4, the movable column 4 may be positioned only by the tension of the wire rope 8.

さらに、布板７の位置を固定（ロック）する位置支持金具、例えば、布板７と固定支柱３を斜め連結する筋交い１４（図５）、Ｌ字金具を備えると、布板７を歩行しても上下の揺れが低減し、足場の安全性が高まる。筋交い１４、Ｌ文金具の形状、連結手段は、特に限定するものではない。ワンタッチで、着脱できる方式が望ましい。 Further, when the cloth plate 7 is provided with a position support metal fitting for fixing (locking) the position of the cloth board 7, for example, a brace 14 (FIG. 5) for diagonally connecting the cloth board 7 and the fixed support column 3, and an L-shaped metal fitting, the cloth board 7 can be walked. However, the vertical swaying is reduced and the safety of the scaffolding is increased. The shapes of the brace 14, the L metal fittings, and the connecting means are not particularly limited. A method that can be attached and detached with one touch is desirable.

駆動部９は、ワイヤーロープ８の一端に接続し、可動支柱４を設置位置から収納位置に引き上げるときにワイヤーロープ８を巻き取り、可動支柱４を収納位置から設置位置に降ろすときにワイヤーロープ８を送り出す。駆動部９は、人手により操作する手動ウインチ、電動モータなどが採用でき、複数本の固定支柱３，可動支柱４のまとまりに一台設置すればよい。 The drive unit 9 is connected to one end of the wire rope 8 and winds the wire rope 8 when the movable support column 4 is pulled up from the installation position to the storage position, and when the movable support column 4 is lowered from the storage position to the installation position. Send out. The drive unit 9 may be a manual winch operated manually, an electric motor, or the like, and one unit may be installed in a group of a plurality of fixed columns 3 and movable columns 4.

第一滑車１０は、ここでは、固定支柱３の底部に設けられ、駆動部９に連結するワイヤーロープ８を駆動部９方向と固定支柱３の長手方向に方向転換する。ワイヤーロープ８の巻き取り、送り出し、足場の使用時に、ワイヤーロープ８が第一滑車１０から脱落しないよう、第一滑車１０及びワイヤーロープ８は、ケース、枠などで囲むことが望ましい、第二滑車１１も同様である。 The first pulley 10 is provided here at the bottom of the fixed column 3, and changes the direction of the wire rope 8 connected to the drive unit 9 between the drive unit 9 direction and the longitudinal direction of the fixed column 3. It is desirable that the first pulley 10 and the wire rope 8 be surrounded by a case, a frame, etc. so that the wire rope 8 does not fall off from the first pulley 10 when the wire rope 8 is wound, fed out, or used in a scaffold. 11 is also the same.

第二滑車１１は、固定位置８ａ及び第一滑車１０より上方の固定支柱３に設けられ、ワイヤーロープ８を第一滑車方向と固定位置８ａ方向に方向転換する。 The second pulley 11 is provided on the fixed column 3 above the fixed position 8a and the first pulley 10, and turns the wire rope 8 in the first pulley direction and the fixed position 8a direction.

上記構成の折り畳み式足場１であれば、通常環境（足場収納）と、作業環境（足場設置）を、簡易に、短時間で転換できるため、通常環境を封鎖し、長期作業環境を確保しなくとも、工事が可能になる。よって、長期足場設置状態での工事が困難、影響が大きい工事において、工事作業の軽減、工期短縮しつつ、通常環境への影響を無くし、或いは最小化して、工事が可能になる。 With the foldable scaffold 1 having the above configuration, the normal environment (scaffold storage) and the work environment (scaffold installation) can be easily switched in a short time. Therefore, the normal environment is blocked and a long-term work environment is not secured. Both will allow construction work. Therefore, it is possible to reduce the construction work and shorten the construction period, and to eliminate or minimize the influence on the normal environment when the construction is difficult and has a large influence on the scaffolding installation state for a long time.
