Description

本発明は、手掛り棒付の作業用足場台及び足場台用手掛り棒保持金具に関する。   The present invention relates to a working scaffold with a cue bar and a cue bar holding metal fitting for the scaffold.

従来、矩形形状の足場板の対向する左右の短辺部それぞれに、脚部を所定角度で開脚自在及び折り畳み自在に設けた作業用足場台があった。   2. Description of the Related Art Conventionally, there has been a work platform in which leg portions are provided at predetermined angles so that the legs can be freely opened and folded at each of the opposing left and right short sides of a rectangular scaffolding plate.

かかる作業用足場台として、前記脚部の両側部に、脚部の脚柱に沿って上下方向に引き出し自在に取付けられた左右一組の手掛り棒からなる手掛部と、前記手掛り棒を突出した状態で保持するロック手段と、前記脚柱の外側に設けられ、前記手掛り棒を摺動自在に保持するガイド金具と、を具備する作業用足場台が知られている(例えば、特許文献1を参照。)。   As such a working platform, a handhold portion composed of a pair of left and right handhold rods attached to both side portions of the leg portions so as to be vertically drawn along the leg pillars of the leg portions, and the handhold rod project. There is known a working scaffolding platform that includes a lock means that holds the clamp bar and a guide fitting that is provided outside the pedestal and holds the cue bar slidably (for example, Patent Document 1). See).

上記構成によれば、手掛り棒は脚柱に沿って上下するため、手掛り棒の一端に設けられた枢軸を中心に回動させるようなタイプに比べて、作業台の周りに広い空間が必要となることもなく、また、足場板に乗らなくとも手掛り棒のセットが容易に行うことができる。   According to the above configuration, since the cue bar moves up and down along the pedestal, a larger space is required around the workbench than a type that rotates around the pivot provided at one end of the cue bar. In addition, the clue bar can be easily set without riding on the scaffolding board.

特開2005−336987号公報JP 2005-336987 A

ところで、上述した作業用足場台では、足場板の短辺部を挟んで対向する左右の手掛り棒間に、踏み外し防止用の横架バーを配設することができる。   By the way, in the work platform described above, a horizontal bar for preventing stepping off can be disposed between the left and right handhold bars facing each other across the short side portion of the scaffold plate.

しかし、上述したように、手掛り棒が脚部の脚柱に沿って上方へ突出していく構成の場合、脚部は所定の開脚角度で正面視略ハ字状に開脚しているため、手掛り棒の上端は、足場板の短辺部の直上方位置よりも、長辺部の中心側へずれることになる。そのため、足場板の作業領域を狭めてしまうおそれがあった。   However, as described above, in the case where the cue bar protrudes upward along the leg column of the leg portion, the leg portion is opened in a substantially C shape in front view at a predetermined leg angle, The upper end of the cue bar will be shifted to the center side of the long side portion rather than the position directly above the short side portion of the scaffold plate. For this reason, there is a possibility that the working area of the scaffolding board is narrowed.

他方、手掛り棒が足場板の四隅から略直上方に突出するような構成とすることも考えられるが、そのような構成とした場合、当然ながら横架バーの位置も足場板の短辺部の直上方位置となるため、作業中に横架バーに身体が接触したときには、すでに足を足場板から踏み外しているということも懸念される。   On the other hand, it is conceivable that the cue bar protrudes from the four corners of the scaffolding plate almost directly above. However, in such a configuration, the position of the horizontal bar is naturally also on the short side of the scaffolding plate. Since the position is directly above, there is also a concern that the foot has already been stepped off from the scaffolding plate when the body contacts the horizontal bar during work.

以下、本発明に係る作業用足場台の一実施形態について、図面を参照しながら具体的に説明する。先ず、図1〜図3を参照しながら、作業用足場台の基本構成について説明する。   Hereinafter, an embodiment of a working scaffold base according to the present invention will be specifically described with reference to the drawings. First, the basic configuration of the working scaffold will be described with reference to FIGS.

(足場台の基本構成)
本実施形態に係る作業用足場台(以下、単に「足場台」という場合がある)は、基本構成として、短辺側縁部10と長辺側縁部11とを有する矩形形状の足場板1と、この足場板1の対向する短辺部をなす短辺側縁部10,10に、それぞれ折畳・開脚自在に取付けられた脚部2,2と、これら脚部2,2の両側部に、上下方向に引き出し自在に取付けられた左右一組の手掛り棒41,41からなる手掛部4とを具備している。
(Basic structure of the scaffolding)
A working scaffolding platform (hereinafter, also simply referred to as “scaffolding platform”) according to the present embodiment is a rectangular scaffolding plate 1 having a short side edge 10 and a long side edge 11 as a basic configuration. And leg portions 2 and 2 which are attached to the short side edge portions 10 and 10 forming the opposite short side portions of the scaffold plate 1 so as to be foldable and openable, respectively, and both sides of the leg portions 2 and 2 And a handle portion 4 including a pair of left and right handle rods 41 and 41 attached to be freely drawn up and down.

すなわち、本実施形態に係る作業用足場台は、足場板1の短辺側縁部10が昇降口となるもので、作業者(足場台の使用者)は、脚部2,2を開脚した状態で脚部2を上り、地上から足場板1に移動して所望する作業を行うことができる。脚部2を上る際や降りる際には、作業者はいずれか一方、あるいは両方の手掛り棒41を把持することによって、その昇降を容易に行うことができる。なお、手掛部4を、本実施形態では足場板1の短辺側縁部10,10の両方に設けているが、少なくともいずれか一方に設けられていればよい。   That is, in the working platform according to the present embodiment, the short side edge 10 of the scaffolding plate 1 serves as a lift, and the operator (user of the platform) opens the legs 2 and 2. In this state, it is possible to go up the leg 2 and move from the ground to the scaffold plate 1 to perform a desired work. When ascending or descending the leg portion 2, the operator can easily raise or lower it by grasping one or both of the cue bars 41. In addition, although the handle part 4 is provided in both the short side edge parts 10 and 10 of the scaffold board 1 in this embodiment, it should just be provided in at least any one.

本実施形態に係る足場板1は、短辺側縁部10と長辺側縁部11との長さの比を略1:3としている。また、足場板1の表面には、図示しないが多数の滑り止め孔がバーリング加工により形成されている。なお、当然ではあるが、複数の作業者が同時に乗っても耐えうる十分な強度を有するものである。   In the scaffold plate 1 according to the present embodiment, the ratio of the lengths of the short side edge 10 and the long side edge 11 is approximately 1: 3. In addition, a number of non-slip holes (not shown) are formed on the surface of the scaffold plate 1 by burring. As a matter of course, it has sufficient strength to withstand even if a plurality of workers ride at the same time.

左右の脚部2は、左右一対の脚柱21,21により略ハ字状となるように裾広がりの形状に形成されるとともに、それぞれ最大に開脚させたときに、足場板1から所定の角度で下り傾斜となって立脚するように構成されている。   The left and right leg portions 2 are formed in a hem-extended shape so as to be substantially C-shaped by a pair of left and right limbs 21 and 21, and when the legs are opened to the maximum, a predetermined amount is provided from the scaffold plate 1 It is configured to stand on a downward slope at an angle.

また、本実施形態では、脚部2,2の開脚角度を、左右それぞれで異ならせた足場台としている。すなわち、図1において右側の脚部2については、開脚角度を107.5度(床面からの角度は72.5度)に設定する一方、左側の脚部2の開脚角度は100度(床面からの角度は80度)に設定して、より起立した状態としている。なお、この開脚角度については適宜設定することができる。   Moreover, in this embodiment, it is set as the scaffolding base from which the leg-opening angle of the leg parts 2 and 2 was different in each right and left. That is, for the right leg 2 in FIG. 1, the leg angle is set to 107.5 degrees (the angle from the floor is 72.5 degrees), while the leg angle of the left leg 2 is 100 degrees. (An angle from the floor surface is set to 80 degrees), which is a more upright state. In addition, about this leg angle, it can set suitably.

また、図2に示すように、右側の脚部2については、脚柱21,21間に複数の踏桟22を所定間隔をあけて取付けて梯子状に構成して昇降可能とする一方、図1において左側の脚部2については、ステップとして機能する踏桟22は設けずに、脚柱21,21間には交差状の補強桟24を取り付けている(図3参照)。   In addition, as shown in FIG. 2, for the right leg 2, a plurality of step bars 22 are attached at predetermined intervals between the pillars 21, 21 and configured as a ladder so as to be movable up and down. In FIG. 1, the left leg 2 is not provided with a stepping bar 22 that functions as a step, and a cross-shaped reinforcing bar 24 is attached between the leg columns 21 and 21 (see FIG. 3).

例えば、壁塗り作業などを行う場合であって、壁と壁とで挟まれたコーナー近傍で作業する際には、より起立した状態の脚部(例えば左側の脚部2)を壁際に可及的に近接させれば、作業領域を壁の隅側にシフトさせることができ、作業効率を向上させることができる。   For example, when performing a wall painting operation, etc., when working near a corner sandwiched between walls, the leg portion in a more upright state (for example, the left leg portion 2) is as close to the wall as possible. If they are close to each other, the work area can be shifted to the corner of the wall, and work efficiency can be improved.

また、脚柱21は、下端部分が入れ子構造となっており、図示するように、所定長さLだけ伸長自在に構成されている。図中、符号GLは接地面を示している。また、符号40で示したものは、足場板1の両端側と左右の各脚柱21の最上段の踏桟22との間に所定間隔をあけて配設した左右一組の開き止め金具であり、この開き止め金具40,40により、足場板1を安定した状態で保持することができる。   Further, the lower end portion of the pedestal 21 has a nested structure, and is configured to be extendable by a predetermined length L as illustrated. In the figure, reference sign GL indicates a ground plane. Also, what is denoted by reference numeral 40 is a pair of left and right opening stoppers disposed at predetermined intervals between both ends of the scaffold plate 1 and the uppermost step rail 22 of each of the left and right pedestals 21. Yes, it is possible to hold the scaffolding plate 1 in a stable state by the opening metal fittings 40, 40.

上述した基本構造を有する足場台において、本実施形態の特徴をなす構成は、脚部2の両側部にそれぞれ取付けられて、手掛り棒41を取付姿勢調整自在に保持可能とした棒保持部8にある。   In the scaffolding platform having the basic structure described above, the configuration that characterizes the present embodiment is that the rod holding portion 8 is attached to both side portions of the leg portion 2 to hold the cue rod 41 so that the attachment posture can be adjusted. is there.

すなわち、棒保持部8により保持された手掛り棒41の姿勢を、脚部2の脚柱21に沿って足場板1に対して斜め方向に突出する傾斜姿勢(図1における仮想線を参照)と、足場板1に対して略垂直方向に突出する直立姿勢(図1における実線を参照)とに選択的に切り替えることができるようにしている。なお、ここでは、取付姿勢を調整可能とした棒保持部8は一方の脚部2にのみ取付けており、他方の脚部2には、手掛り棒41を脚柱21に沿ってのみ摺動自在とした固定式のガイド体9を設けている。   That is, the posture of the clue bar 41 held by the rod holding portion 8 is inclined with respect to the scaffolding plate 1 along the leg column 21 of the leg portion 2 (see the phantom line in FIG. 1). Further, it is possible to selectively switch to an upright posture (see a solid line in FIG. 1) that protrudes in a substantially vertical direction with respect to the scaffold plate 1. Here, the rod holding portion 8 whose attachment posture can be adjusted is attached only to one leg portion 2, and the cue rod 41 is slidable only along the leg pillar 21 to the other leg portion 2. The fixed guide body 9 is provided.

また、ここでは、傾斜姿勢と直立姿勢とのいずれかからの2者択一としているが、複数段の姿勢を選択可能とすることもできるし、起立姿勢から任意の傾斜姿勢まで無段階に姿勢調整することも可能である。   In addition, here, one of the inclined posture and the upright posture is selected, but a plurality of postures can be selected, and the posture is stepless from a standing posture to an arbitrary inclined posture. It is also possible to adjust.

このように、手掛り棒41の取付姿勢を、傾斜角度(ここでは、0度又は17.5度)を変えることで調整可能としたため、脚部2を昇降する使用者(作業者)は、手掛り棒41を、自分の昇降し易い好みに合った位置(姿勢)となるように調整することができる。   As described above, since the attachment posture of the cue bar 41 can be adjusted by changing the inclination angle (here, 0 degrees or 17.5 degrees), the user (operator) who moves up and down the leg portion 2 has a cue. The bar 41 can be adjusted so as to be in a position (posture) that suits the user's preference to easily move up and down.

特に、左右一組の手掛り棒41,41間に、足場板1の短辺側縁部10からの踏み外しを防止する横架バー5を配設することができ、かかる横架バー5を取付ける際に、作業領域が狭くならないことを優先したり、あるいは足場板1からの踏み外しを可及的に防止することを優先したりするなど、使用者が選択することができる。   In particular, a horizontal bar 5 that prevents stepping off from the short side edge 10 of the scaffolding plate 1 can be disposed between the pair of left and right handhold bars 41, 41. In addition, the user can select to give priority to the work area not to be narrowed or to give priority to preventing the work board from being stepped off as much as possible.

すなわち、手掛り棒41,41が傾斜姿勢にある場合は、横架バー5の位置が足場板1の長辺端部(短辺側縁部10)よりも長辺中心方向へシフトするため作業領域は狭くなるが、足場板1からの踏み外し防止機能としては高まる。他方、手掛り棒41,41が直立姿勢にある場合は、横架バー5の位置は足場板1の長辺端部(短辺側縁部10)の直上方位置にあるため、十分な作業領域を確保することができる。   That is, when the cue bars 41 and 41 are in an inclined posture, the position of the horizontal bar 5 shifts from the long side end portion (short side side edge portion 10) of the scaffolding plate 1 toward the long side center direction. Is reduced, but it is enhanced as a function to prevent stepping off from the scaffolding plate 1. On the other hand, when the cue bars 41, 41 are in the upright posture, the horizontal bar 5 is positioned immediately above the long side end portion (short side edge portion 10) of the scaffold plate 1, so that a sufficient work area is obtained. Can be secured.

以下、図4〜図14を参照しながら、棒保持部8を備える足場台について、手掛部4を構成する一対の手掛り棒41,41間に横架バー5が設けられた足場台を例にして詳細に説明する。また、以下で説明する足場台は、図4及び図5に示すように、足場板1の長辺側縁部11を挟んで対向する手掛り棒41,41の各上端間には手摺3を配設している。   Hereinafter, with reference to FIGS. 4 to 14, an example of a scaffolding base including the bar holding portion 8 is a scaffolding base in which a horizontal bar 5 is provided between a pair of handholding bars 41, 41 constituting the hooking portion 4. This will be described in detail. In addition, as shown in FIGS. 4 and 5, the scaffolding platform described below is arranged with handrails 3 between the upper ends of the hook bars 41, 41 facing each other with the long side edge 11 of the scaffolding plate 1 interposed therebetween. Has been established.

(横架バーと手摺とを備えた足場台)
手摺3は、足場板1の対向する長辺側縁部11,11に沿って、互いに対向状態に2本1組で設けられるとともに、スライド自在に嵌装される内装部材3aと外装部材3bとからなる二重構造となっている。したがって、図4に示す手掛り棒41が傾斜姿勢をとる場合と、図6に示すように手掛り棒41が直立姿勢をとる場合とでは、手摺3を横架している手掛り棒4,4間の水平距離が変化するが、手摺3は手掛り棒41の上下スライド動作に追従して伸縮する。
(Scaffolding stand with horizontal bar and handrail)
The handrail 3 is provided as a pair in a state of being opposed to each other along the opposing long side edges 11, 11 of the scaffold plate 1, and an interior member 3 a and an exterior member 3 b that are slidably fitted. It has a double structure consisting of Therefore, when the cue bar 41 shown in FIG. 4 takes an inclined position and when the cue bar 41 takes an upright position as shown in FIG. Although the horizontal distance changes, the handrail 3 expands and contracts following the vertical sliding motion of the cue bar 41.

ここで、図6〜図13を参照して棒保持部8について説明する。足場台の棒保持部8としては、実質的には、足場板1に取付けられた脚部2の両側の脚柱21に取付けられ、手掛り棒41を摺動自在に保持するとともに、所定位置で固定可能とした足場台用手掛り棒保持金具(以下、「保持金具」ともいう)80からなる。   Here, the rod holding portion 8 will be described with reference to FIGS. The scaffolding bar holding portion 8 is substantially attached to the pedestal 21 on both sides of the leg 2 attached to the scaffolding plate 1 to hold the cue rod 41 slidably and at a predetermined position. It consists of a scaffolding cue bar holding metal fitting (hereinafter also referred to as “holding metal fitting”) 80 that can be fixed.

図7〜図12に示すように、保持金具80は、脚部2の左右一対の脚柱21,21の外側面に固着されるベース金具81と、このベース金具81の表面上部に、枢軸82を中心に回動自在に取付けられた棒受金具83とを備えている。   As shown in FIGS. 7 to 12, the holding fitting 80 includes a base fitting 81 fixed to the outer surfaces of the pair of left and right leg posts 21, 21 of the leg portion 2, and a pivot 82 on the upper surface of the base fitting 81.
