Description

この発明は、昇降式足場装置に関し、より詳細には、放射線、電磁波などの遮蔽や遮音などの特定の機能を備えた機能付きボード(資材)の運搬・施工作業に適した昇降式の足場装置に関する。 The present invention relates to an elevating scaffolding device, and more specifically, an elevating scaffolding device suitable for transporting and constructing a functional board (material) having specific functions such as shielding and sound insulation of radiation and electromagnetic waves. Regarding.

放射線や電磁波の遮蔽、遮音など特定の機能を備えた部屋(放射線室、シールドルーム、防音室など)を構築する場合、その部屋や隣接する部屋・廊下などの壁面に、特定の機能を付与する機能付きのボードを取り付けることがある。 When constructing a room with specific functions such as radiation and electromagnetic wave shielding and sound insulation (radiation room, shield room, soundproof room, etc.), add specific functions to the wall surface of the room, adjacent room, corridor, etc. A functional board may be installed.

たとえば、放射線室を構築する場合、図4に示すように、放射線遮蔽材(たとえば、鉛板)を備えた放射線遮蔽機能付きのボードaを、放射線室の壁面Wなどに隙間なく壁一面に貼り付けている。 For example, when constructing a radiation chamber, as shown in FIG. 4, a board a having a radiation shielding function equipped with a radiation shielding material (for example, a lead plate) is attached to the wall surface W of the radiation chamber without any gaps. It is attached.

図4に示す施工例は、階高L1が4500mmの壁面Wに、放射線遮蔽機能を備えたボードaを上下3段に配置した場合を示しており、図示例では、下段および中段に高さL2が1820mm、幅L3が910mmの大型のボードa1を配設し、これら下段および中段のボードa1によっては覆いきれない残余のスペースである上段に高さL4が710mm、幅L3が910mmの小型のボードa2を配設することによって、壁面Wの全面をボードaで覆うように施工している。 The construction example shown in FIG. 4 shows a case where a board a having a radiation shielding function is arranged in three upper and lower stages on a wall surface W having a floor height L1 of 4500 mm. A large board a1 having a height of 1820 mm and a width of L3 of 910 mm is arranged, and a small board having a height L4 of 710 mm and a width of L3 of 910 mm is placed on the upper stage, which is a residual space that cannot be covered by the lower and middle board a1. By arranging a2, the entire surface of the wall surface W is covered with the board a.

ところで、このような機能付きのボードaは、上述した放射線遮蔽材の鉛板のように、ボードに特定の機能を付与する機能材が備えられているため、小型のボードa2であっても1枚あたりの重さが十数kgを超え、大型のボードa1においては数十kg(たとえば、60kg)程度の重さになることがある。そのため、この種のボードaを、図4に示すように多段に配置するためには、2段目より上の段に配設するボードaは、昇降式の足場装置b(たとえば、特許文献1の「高所作業車」を参照)を用いて所望の高さ位置まで持ち上げて貼り付けるようにしている。 By the way, since the board a with such a function is provided with a functional material that imparts a specific function to the board like the lead plate of the radiation shielding material described above, even a small board a2 1 The weight per sheet exceeds a dozen kg, and the large board a1 may weigh several tens of kg (for example, 60 kg). Therefore, in order to arrange this type of board a in multiple stages as shown in FIG. 4, the board a arranged in the stage above the second stage is an elevating scaffolding device b (for example, Patent Document 1). (Refer to "Aerial work platform") to lift and paste to the desired height position.

図5はこの種の昇降式の足場装置bの一例を示している。図5に示す昇降式の足場装置bは、足場cを上下に昇降移動させる昇降機構dを備えており、作業員がこの昇降機構dを操作することによって、足場cを任意の高さ位置に昇降させることができるようになっている。出願人は、このような足場装置bの側方にボードaを載置する載置台eを取り付け、足場cの上昇に伴って載置台eに載置したボードaが持ち上げられるようにし、このような足場装置bを使ってボードaを2段目より上の段の位置まで持ち上げ、その状態から壁面Wへの貼り付けを行っている。 FIG. 5 shows an example of this type of elevating scaffolding device b. The elevating scaffolding device b shown in FIG. 5 is provided with an elevating mechanism d that moves the scaffold c up and down, and a worker operates the elevating mechanism d to move the scaffold c to an arbitrary height position. It can be raised and lowered. The applicant attaches a mounting table e on which the board a is placed to the side of such a scaffolding device b so that the board a placed on the mounting table e can be lifted as the scaffolding c rises. The board a is lifted to the position of the second step or higher by using the scaffolding device b, and the board a is attached to the wall surface W from that state.

しかしながら、このような従来のやり方には以下の問題があった。
すなわち、足場cの側面に設けた載置台eにボードaを載せて持ち上げる方法では、図6の左側に図示するように、天井までのスペースに余裕がある中段へのボードa1の取り付け作業は、載置台eを中段の高さ位置(中段の施工ラインCL1)まで上昇させ、この状態でボードa1を載置台eから壁面Wに移し替えながら壁面Wに貼り付けることができるが、天井までのスペースに余裕がなく、ダクトDなどの障害物もある上段へのボードa2の取り付け作業では、ボードaが上段の高さ位置(上段の施工ラインCL2)に配置されるまで足場cを上昇させようとすると、足場cと天井との隙間が狭くなりすぎて作業員が起立状態で作業することができなくなったり、あるいは、足場装置bとダクトDとが接触干渉するなどして、足場cを所望の高さ位置まで上昇させることができない。そのため、現状では、上段へのボードaの取付作業にあたっては、図6の右側に図示するように、足場cを中段の中ほどの高さ位置で止め、そこから上段の高さ位置までボードa2を人力で持ち上げて(図6の右側の矢符参照)、ボードa2の取付作業を行っており、重量のあるボードaの上げ下ろしに多大の労力が必要であった。
However, such a conventional method has the following problems.
That is, in the method of mounting the board a on the mounting table e provided on the side surface of the scaffold c and lifting it, as shown on the left side of FIG. 6, the work of attaching the board a1 to the middle stage where there is enough space to the ceiling is performed. The mounting table e can be raised to the height position of the middle stage (construction line CL1 in the middle stage), and in this state, the board a1 can be attached to the wall surface W while being transferred from the mounting table e to the wall surface W, but the space to the ceiling. In the work of attaching the board a2 to the upper stage where there is no room and there are obstacles such as duct D, the scaffolding c is raised until the board a is placed at the height position of the upper stage (construction line CL2 in the upper stage). Then, the gap between the scaffolding c and the ceiling becomes too narrow and the worker cannot work in an upright position, or the scaffolding device b and the duct D contact and interfere with each other, so that the scaffolding c is desired. It cannot be raised to the height position. Therefore, at present, when attaching the board a to the upper stage, as shown on the right side of FIG. 6, the scaffolding c is stopped at the middle height position of the middle stage, and the board a2 is stopped from there to the height position of the upper stage. Was manually lifted (see the arrow on the right side of FIG. 6) to attach the board a2, and a great deal of labor was required to raise and lower the heavy board a.

本発明は、このような問題点に鑑みてなされたものであって、その目的とするところは、天井等とのスペースが少ない場所への重量のあるボードの取付作業を容易に行うことができる昇降式の足場装置を安価に提供することにある。 The present invention has been made in view of such problems, and an object of the present invention is that a heavy board can be easily attached to a place where there is little space with a ceiling or the like. The purpose is to provide an elevating scaffolding device at a low cost.

A guide portion extending in the vertical direction on the side of the scaffold portion, a mounting base portion on which a plate-shaped material can be placed and which can be moved in the vertical direction along the guide portion. It is characterized by having a drive mechanism portion for moving the above-mentioned pedestal portion up and down along the guide portion.

以下、本発明の実施形態を図面に基づいて詳細に説明する。
本発明に係る昇降式足場装置1は、特定の機能が付与されたボード(たとえば、放射線遮蔽、電磁波遮蔽、遮音などの機能が付与されたボード)100を壁面Wに取り付ける作業、特に、高さ方向に多段にボード100を取り付ける作業に適した昇降式の足場装置であって、上下方向に移動可能に構成された足場部2と、足場部2を水平方向に移動可能に構成する走行機構部3と、足場部2の側方に上下方向に延びて設けられるガイド部4と、ボード100などの資材を載置でき、かつ、ガイド部4に沿って上下方向に移動可能に構成された載置台部5と、載置台部5をガイド部4に沿って上下移動させる駆動機構部6とを主要部として備えている。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The elevating scaffolding device 1 according to the present invention is a work of attaching a board to which a specific function is given (for example, a board to which functions such as radiation shielding, electromagnetic wave shielding, sound insulation, etc.) 100 are attached to a wall surface W, particularly height. An elevating scaffolding device suitable for the work of mounting the board 100 in multiple stages in the direction, the scaffolding portion 2 configured to be movable in the vertical direction and the traveling mechanism portion constituting the scaffolding portion 2 to be movable in the horizontal direction. 3 and a guide portion 4 extending in the vertical direction to the side of the scaffold portion 2 and a material such as a board 100 can be placed and mounted so as to be movable in the vertical direction along the guide portion 4. A pedestal portion 5 and a drive mechanism portion 6 for moving the pedestal portion 5 up and down along the guide portion 4 are provided as main portions.

足場部2は、作業員の作業スペースとなる作業床21と、作業床21の周囲に設けられる脱落防止柵22と、作業床21を上下方向に移動させる昇降機構23とを主要部として有している。図示の作業床21は、図1の左右方向を長手方向とする(平面視において)略長方形状の平坦な床面を有しており、この床面の周囲には高さ数cm程度の周壁24が設けられ、作業床上に置かれたビスなどの小さな物品が外部に転がり落ちないようになっている。 The scaffolding portion 2 has a work floor 21 as a work space for workers, a fall prevention fence 22 provided around the work floor 21, and an elevating mechanism 23 for moving the work floor 21 in the vertical direction as main parts. ing. The illustrated work floor 21 has a flat floor surface having a substantially rectangular shape (in a plan view) with the left-right direction of FIG. 1 as the longitudinal direction, and a peripheral wall having a height of about several cm is around the floor surface. 24 is provided to prevent small items such as screws placed on the work floor from rolling down to the outside.

脱落防止柵22は、作業床21上で作業する作業員が落下するのを防止するための柵であって、図示例では、作業床21の周囲に、高さ1~1.5m程度の手摺を配置したような形状の柵が設けられている。なお、この脱落防止柵22は、作業員の落下防止の目的が達成できる形状であればよく、その具体的な形状は適宜変更可能である。 The dropout prevention fence 22 is a fence for preventing workers working on the work floor 21 from falling, and in the illustrated example, a handrail having a height of about 1 to 1.5 m is provided around the work floor 21. There is a fence shaped like the one in which. The fall prevention fence 22 may have a shape that can achieve the purpose of preventing the worker from falling, and the specific shape thereof can be changed as appropriate.

昇降機構23は、作業床21を上下方向に移動させるための機構であって、図示例では、作業床21の短手方向の側面に設けられた伸縮自在の柱状の形態とされ、図示しない昇降動作用の操作パネルの操作に応じて図外の駆動部が作動することにより、柱状の昇降機構23の柱部分が伸縮して作業床21(足場部2)の高さ位置を変更できるようになっている。なお、本実施形態では、昇降機構23が柱状の駆動機構で構成された場合を示したが、作業床21を上下方向に移動できる構造であれば、たとえば、作業床21の下に設けられた伸縮式のシザーアームの形態であってもよい。 The elevating mechanism 23 is a mechanism for moving the work floor 21 in the vertical direction. In the illustrated example, the elevating mechanism 23 has a form of a stretchable columnar provided on the side surface of the work floor 21 in the lateral direction, and is not shown. By operating the drive unit (not shown) in response to the operation of the operation panel for operation, the pillar portion of the columnar elevating mechanism 23 expands and contracts so that the height position of the work floor 21 (scaffolding portion 2) can be changed. It has become. In the present embodiment, the case where the elevating mechanism 23 is composed of a columnar drive mechanism is shown, but if the structure is such that the work floor 21 can be moved in the vertical direction, for example, it is provided under the work floor 21. It may be in the form of a telescopic scissor arm.

走行機構部3は、上述したように、足場部2を水平方向に移動可能にするための機構で構成されている。本実施形態では、この走行機構部3は、車台部31と、車台部31に設けられた4つの車輪32と、車輪32の動力源(図示せず)とを有している。 As described above, the traveling mechanism unit 3 is composed of a mechanism for making the scaffolding unit 2 movable in the horizontal direction. In the present embodiment, the traveling mechanism portion 3 has a chassis portion 31, four wheels 32 provided on the chassis portion 31, and a power source (not shown) of the wheels 32.

車台部31は、作業床21を支持する台車であって、この車台部31は車輪32によって水平方向に移動可能に構成されている。車輪32の動力源としては、たとえば、電動モータが用いられるが、電動モータ以外の動力源で動くものであってもよい。そして、この車台部31は、足場部2に設けられた操作パネル(図示例では、昇降機構23の上端位置に設けられている)7を用いて操縦可能になっており、作業床21上の作業員が車台部31の水平移動を自在に操縦できるようになっている。なお、足場部2および走行機構部3を備える足場装置としては、市販されている既製の高所作業車を用いることにより、これらの製造コストを安価に抑えることができる。本実施形態では、これら足場部2および走行機構部3として既製品の高所作業車を用いている。 The chassis portion 31 is a carriage that supports the work floor 21, and the chassis portion 31 is configured to be movable in the horizontal direction by the wheels 32. As the power source of the wheel 32, for example, an electric motor is used, but a power source other than the electric motor may be used. The chassis portion 31 can be steered by using an operation panel (provided at the upper end position of the elevating mechanism 23 in the illustrated example) 7 provided on the scaffolding portion 2, and is on the work floor 21. The worker can freely control the horizontal movement of the chassis portion 31. As the scaffolding device provided with the scaffolding unit 2 and the traveling mechanism unit 3, a commercially available aerial work platform can be used, so that the manufacturing cost thereof can be suppressed at low cost. In this embodiment, an off-the-shelf aerial work platform is used as the scaffolding portion 2 and the traveling mechanism portion 3.

ガイド部4は、載置台部5の上下方向の移動を案内するためのガイドレールを構成するものであって、足場部2の側方に上下方向に延びるように設けられている。そして、本実施形態では、このガイド部4として、梯子を使った荷揚げ装置の梯子部分が用いられている。すなわち、本実施形態では、このガイド部4、載置台部5および駆動機構部6を構成するものとして、梯子を使った市販(既製品)の荷揚げ装置を用いており、その梯子部分を足場部2の側面に取り付け固定することによってガイド部4を形成している。 The guide portion 4 constitutes a guide rail for guiding the vertical movement of the mounting base portion 5, and is provided so as to extend in the vertical direction to the side of the scaffolding portion 2. Further, in the present embodiment, a ladder portion of the unloading device using a ladder is used as the guide portion 4. That is, in the present embodiment, a commercially available (off-the-shelf) unloading device using a ladder is used as a component of the guide portion 4, the mounting base portion 5, and the drive mechanism portion 6, and the ladder portion is used as a scaffolding portion. The guide portion 4 is formed by attaching and fixing to the side surface of 2.

具体的には、ガイド部4を構成する梯子部分は、図1に示すように、梯子の下端部分が床面FLの近傍に位置するように配置される。ここで、梯子部分の下端位置は、後述する載置台部5へのボード100の積み下ろしの容易性を考慮すると、できる限り床面FLに近いのが好ましいが、あまりに床面FLに近づきすぎると、走行時に梯子の下端部分が床面FLと接触して走行の妨げになるおそれがあるので、床面FLとの間に数cm程度の隙間ができるように構成しておくのが好ましい。 Specifically, as shown in FIG. 1, the ladder portion constituting the guide portion 4 is arranged so that the lower end portion of the ladder is located in the vicinity of the floor surface FL. Here, the lower end position of the ladder portion is preferably as close to the floor surface FL as possible in consideration of the ease of loading and unloading the board 100 on the mounting table portion 5, which will be described later, but if it is too close to the floor surface FL, Since the lower end portion of the ladder may come into contact with the floor surface FL during traveling and hinder the traveling, it is preferable to configure the ladder so that there is a gap of about several cm between the ladder surface and the floor surface FL.

これに対し、梯子部分の長さ、すなわち、載置台部5の上昇上限の高さは、作業床21上に起立した作業員が起立状態でボード100を持ち運びできる程度の高さ、具体的には、たとえば、載置台部5に載置されたボード100を足場部2の床面(作業床21の床面)から1m乃至2mの高さ位置にまで引き上げ可能な長さ寸法とされる。これにより、載置台部5に載置されたボード100を作業員の胸元や目線の高さ程度の位置まで持ち上げて作業することができるようになる。 On the other hand, the length of the ladder portion, that is, the height of the upper limit of the rise of the mounting table portion 5, is such that a worker standing on the work floor 21 can carry the board 100 in an upright state, specifically. Is, for example, a length dimension that allows the board 100 mounted on the mounting table portion 5 to be pulled up to a height position of 1 m to 2 m from the floor surface of the scaffolding portion 2 (floor surface of the work floor 21). As a result, the board 100 mounted on the mounting table portion 5 can be lifted to a position about the height of the worker's chest or line of sight for work.

載置台部5は、荷揚げ装置に備え付けの荷台部分を用いることもできるが、本実施形態では、この載置台部5は、図2に示すように、先端部が略コ字状に曲折されて鉤状を呈する金具で構成されている。すなわち、この載置台部5は、図2に示すように、板状のボード100を載置した際に、載置台部5の先端部分がボード100の下端部を挟み込んでその脱落を防止しつつ支持できる構造とされている。 As the loading platform portion 5, a loading platform portion provided in the unloading device can be used, but in the present embodiment, the loading platform portion 5 has a tip portion bent in a substantially U-shape as shown in FIG. It is composed of metal fittings that have a hook shape. That is, as shown in FIG. 2, when the plate-shaped board 100 is mounted on the mounting base portion 5, the tip portion of the mounting base portion 5 sandwiches the lower end portion of the board 100 to prevent the board 100 from falling off. It has a structure that can be supported.

駆動機構部6は、梯子を使った荷揚げ装置において荷台部分(載置台部5)を持ち上げるのに使用する動力機構で構成される。本実施形態では、この駆動機構部6は、先端部が載置台部5に連結されたワイヤ61と、ワイヤ61を巻き上げる電動ウインチ(原動機付きウインチ)62とで構成されている。電動ウインチ62は、図示しないウインチ操作部を操作すことによってワイヤ61の巻き上げ/巻き戻しが自動で行われるように構成されており、これによって、載置台部5が荷揚げ装置の梯子部分(ガイド部4)に沿って上下に移動するように構成されている。なお、本実施形態ではワイヤ61の巻き上げ/巻き戻しに原動機付のウインチを用いた場合を示したが、手動の巻き上げハンドルを備えた手動ウインチを用いることも勿論可能である。 The drive mechanism unit 6 is composed of a power mechanism used to lift the loading platform portion (mounting platform portion 5) in the unloading device using a ladder. In the present embodiment, the drive mechanism portion 6 is composed of a wire 61 whose tip portion is connected to the mounting base portion 5 and an electric winch (motorized winch) 62 that winds up the wire 61. The electric winch 62 is configured so that the wire 61 is automatically wound / rewound by operating a winch operation unit (not shown), whereby the mounting base portion 5 is configured as a ladder portion (guide portion) of the unloading device. It is configured to move up and down along 4). In the present embodiment, the case where a winch with a prime mover is used for winding / rewinding the wire 61 is shown, but it is also possible to use a manual winch provided with a manual winding handle.

次に、このように構成された昇降式足場装置1を用いたボード100の壁面Wへの取付作業について、図3を参照しながら説明する。 Next, the work of attaching the board 100 to the wall surface W using the elevating scaffolding device 1 configured in this way will be described with reference to FIG.

図3に示すボード100の施工例は、図4に示す施工例と同様に、階高L1が4500mmの壁面Wに放射線遮蔽機能を備えたボード100を上下3段に取り付ける場合を示しており、下段および中段には高さL2が1820mm、幅L3が910mmの大型のボード100aを取り付け、これら下段および中段のボード100aによっては覆いきれない残余のスペースである上段には高さL4が710mm、幅L3が910mmの小型のボード100bを取り付ける場合を例示している。 The construction example of the board 100 shown in FIG. 3 shows a case where the board 100 having a radiation shielding function is attached to a wall surface W having a floor height L1 of 4500 mm in three upper and lower stages, similarly to the construction example shown in FIG. A large board 100a with a height L2 of 1820 mm and a width L3 of 910 mm is attached to the lower and middle tiers, and a height L4 of 710 mm and a width of 710 mm is attached to the upper tier, which is a residual space that cannot be covered by the lower and middle tier boards 100a. The case where a small board 100b having an L3 of 910 mm is attached is illustrated.

図3の左側に示すように、天井までのスペースに余裕がある下段および中段へのボード100aの取り付け作業は、まず、ボード100aを載置台部5に載置した昇降式足場装置1をボード100aの取付位置(ボード100aを取り付ける壁面Wと対面する位置)まで水平移動させる。このとき、昇降式足場装置1は、載置台部5が設けられた側が壁面Wと対面するようにする。そしてその状態で、電動ウインチ62を操作して載置台部5を下端位置、すなわち、床面LF近傍の高さ位置まで下げる。そして、壁面下段へのボード100aの取り付けにあたっては、この状態から作業床21上の作業員が人力でボード100aを少し持ち上げて、ボード100aの下端部分を載置台部5のコ字状部分から取り外し、壁面Wの下段の所定位置に移し替えて貼り付ける。 As shown on the left side of FIG. 3, in the work of attaching the board 100a to the lower and middle stages where there is room to the ceiling, first, the elevating scaffolding device 1 on which the board 100a is mounted on the mounting base 5 is mounted on the board 100a. Is horizontally moved to the mounting position (position facing the wall surface W on which the board 100a is mounted). At this time, in the elevating scaffolding device 1, the side on which the mounting base portion 5 is provided faces the wall surface W. Then, in that state, the electric winch 62 is operated to lower the mounting table portion 5 to the lower end position, that is, the height position near the floor surface LF. Then, when attaching the board 100a to the lower part of the wall surface, a worker on the work floor 21 manually lifts the board 100a from this state and removes the lower end portion of the board 100a from the U-shaped portion of the mounting table portion 5. , Move it to a predetermined position on the lower part of the wall surface W and paste it.

次に、壁面中段へのボード100aの取り付けは、下段への貼り付けと同様に、まず、ボード100aを載置台部5に載置した昇降式足場装置1をボード100aの取付位置まで水平移動させる。そして、次に昇降式足場装置1の昇降機構23を操作して、載置台部5が壁面中段への施工位置(中段の施工ラインCL1の高さ位置)の近傍に位置するようにし、この状態から上記同様に作業床21上にいる作業員が人力でボード100aを少し持ち上げて載置台部5から取り外し、壁面Wの中段の所定位置に移し替えて貼り付ける。 Next, for mounting the board 100a on the middle stage of the wall surface, first, the elevating scaffolding device 1 on which the board 100a is mounted on the mounting table portion 5 is horizontally moved to the mounting position of the board 100a, as in the case of pasting on the lower stage. .. Then, the elevating mechanism 23 of the elevating scaffolding device 1 is operated so that the mounting base portion 5 is located near the construction position on the middle stage of the wall surface (the height position of the construction line CL1 in the middle stage), and this state. Similarly to the above, a worker on the work floor 21 manually lifts the board 100a a little, removes it from the mounting table portion 5, transfers it to a predetermined position in the middle of the wall surface W, and attaches it.

なお、このときの載置台部5の高さ位置の調節は、上述したように昇降式足場装置1の昇降機構23だけで行ってもよいが、載置台部5を上下移動させる駆動機構部6を併用して載置台部5の高さ位置の微調整を行ってもよい。 The height position of the mounting base 5 at this time may be adjusted only by the lifting mechanism 23 of the lifting scaffolding device 1 as described above, but the drive mechanism 6 for moving the mounting base 5 up and down. May be used in combination to make fine adjustments to the height position of the mounting table portion 5.

そして最後に、壁面上段へのボード100bの取り付けは、図3の右側に図示するように、まず、ボード100bを載置台部5に載置した昇降式足場装置1をボード100bの取付位置まで水平移動させるのは、下段および中段への取り付けと同様である。そして、この状態から昇降式足場装置1の昇降機構23を操作して、載置台部5の高さ位置を壁面上段のボードの施工位置(CL2)の近傍に位置させる。すなわち、天井等との隙間が少ない上段へのボード100bの施工では、天井等に邪魔されることなく作業床21上の作業員が起立状態で作業できる高さ位置(図示例では、中段の施工ラインL1より高いが、上段の施工ラインL2よりも低い位置)まで移動させる。 Finally, for mounting the board 100b on the upper wall surface, as shown on the right side of FIG. 3, first, the elevating scaffolding device 1 on which the board 100b is mounted on the mounting base 5 is horizontally placed up to the mounting position of the board 100b. Moving is the same as mounting to the lower and middle tiers. Then, from this state, the elevating mechanism 23 of the elevating scaffolding device 1 is operated to position the height position of the mounting table portion 5 in the vicinity of the construction position (CL2) of the board on the upper wall surface. That is, in the construction of the board 100b on the upper stage where there is little gap with the ceiling or the like, the height position where the worker on the work floor 21 can work in an upright state without being disturbed by the ceiling or the like (in the illustrated example, the construction of the middle stage). Move to a position higher than the line L1 but lower than the upper construction line L2).

そして、この状態から駆動機構部6の電動ウインチ62を操作して、載置台部5に載置されたボード100bが壁面上段の施工位置(CL2)の近傍に位置するように、載置台部5の高さ位置を調節する。そして、ボード100bが壁面上段の施工位置(CL2)の近傍まで持ち上げられると、この状態から作業床21上の作業員が人力でボード100bを持ち上げて載置台部5から取り出し、壁面Wの上段位置への貼り付け作業を行う。 Then, from this state, the electric winch 62 of the drive mechanism unit 6 is operated so that the board 100b mounted on the mounting table portion 5 is located near the construction position (CL2) on the upper wall surface. Adjust the height position of. Then, when the board 100b is lifted to the vicinity of the construction position (CL2) on the upper wall surface, a worker on the work floor 21 manually lifts the board 100b from this state and takes it out from the mounting table portion 5, and the upper position of the wall surface W. Perform the work of pasting to.
