Description

この考案は、内装工事等に使用する簡易足場、更に詳しくは、対向配置する二台の梯子とその踏棧間に架設する足場板とで形成され、安定した組立て状態が得られると共に、組立てと解体が簡単に行え、解体時に嵩低くなって格納や搬入に便利な簡易足場に関する。 This device is a simple scaffolding used for interior construction, etc., more specifically, it is formed of two ladders arranged opposite to each other and a scaffolding board erected between the spade, and a stable assembly state is obtained, The present invention relates to a simple scaffolding that can be easily disassembled and is low in bulk during dismantling and is convenient for storing and carrying in.

例えば、建物の内装工事等において、手の届かないような高所位置の作業を行う場合、作業者が載るための足場を用いることになるが、鋼管をパイプジョイントで結合して組み立てる仮設足場では、大掛かりで組み立てと解体に手間と時間がかかり、このような大掛かりな足場では建物内での使用に不向きであるため、建物内への搬入、搬出が容易で簡単に移動できる簡易足場の使用が必要になる。 For example, when performing work in a high place that is out of reach in building interior construction, etc., a scaffold for the operator to use will be used, but in a temporary scaffold that is assembled by joining steel pipes with pipe joints Because it takes a lot of time and labor to assemble and dismantle with a large scale, it is not suitable for use in a building with such a large scale, so it is easy to carry in and out of the building and use a simple scaffold that can be moved easily I need it.

従来、建物の内装工事等における簡易な作業足場としては、一対の梯子脚の上端を踏板の下面両側に結合し、両梯子脚の平行状態での折畳みと両側への開脚が自在となるようにした脚立が一般的に用いられている。 Conventionally, as a simple work scaffolding for building interior construction, etc., the upper ends of a pair of ladder legs are joined to both sides of the lower surface of the tread so that both ladder legs can be folded in parallel and open to both sides. The stepladder is generally used.

ところで、建物の内装工事等においては、作業の進行と共に作業位置を移動しなければならないが、脚立における上端の踏板は平面的に狭く、作業中の移動可能な範囲が制限されているため、作業の進行と共にその都度脚立を移動させなければならず、このような脚立の移動と昇り降りは作業の能率を低下させる原因になっている。 By the way, in the interior construction of a building, the work position must be moved as the work progresses.However, the stepping plate at the upper end of the stepladder is narrow in plan and the movable range during work is limited. The stepladder must be moved as it progresses, and such movement and climbing of the stepladder causes a reduction in work efficiency.

また、脚立は、踏板の下面両側に梯子脚を取付けた構造になっているので、折畳んだ状態でも踏板側が嵩張り、格納や搬入に不便をきたすものである。 Further, since the stepladder has a structure in which ladder legs are attached to both sides of the lower surface of the tread board, the tread board side is bulky even in a folded state, which causes inconvenience in storing and carrying in.

そこで、この考案の課題は、上記した問題点を解決するため、広い作業面積を確保することができ、高所作業の安全性と能率向上に寄与することができ、しかも、組立て及び解体が簡単で解体時に嵩低くなる簡易足場を提供することにある。 Therefore, the problem of the present invention is to solve the above-mentioned problems, so that a wide work area can be secured, which can contribute to safety and efficiency improvement in high-altitude work, and easy to assemble and dismantle. Therefore, it is intended to provide a simple scaffold that becomes low in volume when dismantled.

上記の課題を解決するため、この考案は、二台の梯子と、対向させた二台の梯子の踏棧間に架設する足場板とからなり、二台の梯子の対向させる面で足場板を架設する踏棧よりも上部の位置に、この踏棧との間に足場板を抜き差しできる間隔を設けて足場板押さえ部材を固定し、この足場板押さえ部材の梯子への固定位置が、梯子の所定角度の傾斜配置で足場板を前記踏棧とで挟む位置に設定されている構成を採用したものである。 In order to solve the above problems, the present invention is composed of two ladders and a scaffolding board constructed between the two ladders opposed to each other, and the scaffolding board is formed on the surface facing the two ladders. The scaffolding plate pressing member is fixed at a position above the installed spade so that the scaffolding plate can be inserted into and removed from this spade, and the fixing position of the scaffolding plate pressing member to the ladder is A configuration is adopted in which the scaffolding plate is set at a position where the scaffolding plate is sandwiched between the spade and a predetermined angle of inclination.

上記足場板押さえ部材は、梯子の両側縦柱における外面間の間隔に対応する長さの角パイプを用いて形成され、その両端部が、梯子の両側縦柱で二台の梯子を対向させる面に固定した受け金物で固定支持され、梯子の両側縦柱で二台の梯子を対向させる面に水平に架設されている構造とするができる。 The scaffolding plate pressing member is formed by using a square pipe having a length corresponding to the interval between the outer surfaces of the vertical columns on both sides of the ladder, and both ends thereof are surfaces on which the two ladders are opposed to each other by the vertical columns on both sides of the ladder. It is possible to have a structure in which the two ladders are horizontally supported on the opposite sides of the ladders and are supported horizontally by the receiving hardware fixed to the ladder.

また、上記梯子に設けた踏棧と足場板押さえ部材は、梯子の所定角度の傾斜配置で、踏棧の上面と上記足場板押さえ部材の下面がそれぞれ水平になるように配置され、踏棧の上面と上記足場板押さえ部材の下面の垂直高さの間隔が足場板の厚みに一致しているようにしてもよい。 Further, the spade and the scaffolding plate pressing member provided on the ladder are arranged so that the ladder is inclined at a predetermined angle, and the upper surface of the spade and the lower surface of the scaffolding plate pressing member are respectively horizontal. You may make it the space | interval of the vertical height of an upper surface and the lower surface of the said scaffold board pressing member correspond with the thickness of a scaffold board.

ここで、梯子は、所定長さを有する両側縦柱間に一定間隔で複数の踏棧を架設して形成され、両側縦柱の下端に接地部材が角度可変となるよう取付けられ、踏棧は梯子を所定角度で傾斜させたときその上面が水平になるよう両側縦柱間に架設されている。 Here, the ladder is formed by laying a plurality of spades at predetermined intervals between the vertical columns on both sides having a predetermined length, and the grounding member is attached to the lower end of the vertical columns on both sides so that the angle can be varied. When the ladder is inclined at a predetermined angle, the ladder is installed between the vertical columns on both sides so that the upper surface thereof is horizontal.

簡易足場は、両側の対向させる梯子の踏棧と足場板押さえ部材間にそれぞれ足場板の端部を挿入し、この両側梯子を互に相手側に向けて所定の傾斜角度に傾けて起立させれば、踏棧と足場板押さえ部材で足場板を上下から挟むことで梯子は自立し、足場板で広い面積の作業足場を確保することができる。 The simple scaffolding can be stood by inserting the end of the scaffolding plate between the ladder steps and the scaffolding plate holding members facing each other, and tilting the both ladders toward each other at a predetermined inclination angle. For example, the ladder can stand on its own by sandwiching the scaffolding plate from above and below with the spade and the scaffolding plate pressing member, and a large area work scaffolding can be secured with the scaffolding plate.

また、簡易足場は、対向させた二台の梯子を、相手側に向けて傾斜する起立状態にすることで、踏棧と足場板押さえ部材が足場板を上下からこじるように挟むことになり、これによって、揺れに対する強度の優れた組立て状態になる。 In addition, the simple scaffolding, by placing the two ladders facing each other in an upright state inclined toward the other side, the spade and the scaffolding plate pressing member sandwich the scaffolding plate from above and below, As a result, the assembled state is excellent in strength against shaking.

この考案によると、対向させた二台の梯子の踏棧間に足場板を架設し、両側梯子を所定の傾斜角度にすることで、踏棧と足場板押さえ部材が足場板を上下から挟むようにしたので、足場板によって広い面積の作業足場を確保することができ、作業足場を煩雑に移動させるようなことがなくなり、建物の内装工事等の作業能率の向上が図れることになる。 According to this device, a scaffolding plate is installed between the two ladders facing each other, and the ladders on both sides are set at a predetermined inclination angle, so that the spade and the scaffolding plate pressing member sandwich the scaffolding plate from above and below. As a result, it is possible to secure a large-area work scaffold by the scaffold plate, and it is not necessary to move the work scaffold in a complicated manner, thereby improving the work efficiency of building interior construction and the like.

また、両側梯子の踏棧と足場板押さえ部材間にそれぞれ足場板の端部を挿入するだけで組立てることができ、組立てや解体の作業が容易であると共に、解体時には、二台の梯子と足場板に分解できるので、全体が嵩低くなり、格納や搬送に有利となる。 In addition, it is possible to assemble by simply inserting the end part of the scaffolding plate between the ladder of both sides ladder and the scaffolding plate holding member, assembling and disassembling work is easy. Since it can be disassembled into plates, the whole is low in volume, which is advantageous for storage and transportation.

また、二台の梯子を下部広がりの傾斜状に配置することにより、踏棧と足場板押さえ部材が足場板を上下からこじるように挟むことになり、揺れに対する強度の優れた組立て状態になるので、高所作業の安全性を向上させることができる。 In addition, by placing the two ladders in a slanted shape that spreads downward, the spade and the scaffolding plate pressing member will pinch the scaffolding plate from above and below, resulting in an assembled state with excellent strength against shaking. , Can improve the safety of high-altitude work.
