本発明は高所作業足場、更に詳しくは、船舶建造時にお
ける艙内作業足場として好適な高所作業足場に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a scaffold for working at high places, and more particularly to a scaffold for working at high places suitable as a work scaffold in a hold during ship construction.
−１１に船舶の建造は板材を必要に応じて切断、曲げ加
工等を行ない、これを使用してブロックを形成し、この
ブロックを集合する所謂ブロック建造法が採用されてい
る。-11. In the construction of ships, a so-called block construction method is adopted in which plate materials are cut and bent as necessary, blocks are formed using the plates, and the blocks are assembled.
ところでこのブロック建造法においては、例えば第５図
に示すように複数個のブロックａ〜ｄを接合して船体１
を建造する場合、各ブロック間の接合線ａ′〜Ｃ′及び
縦方向の接合線を溶接する必要があるが、この船体１は
高さｈが数十メートルにもなり、しかも船舶内から溶接
作業を行なわなければならず、そのため艙内に多数の足
場２を架設する必要があった。したがってこの足場２の
架設取外しに多大の時間と労力を必要とするばかりでな
く、その作業は高所作業となり危険な作業となっている
。By the way, in this block construction method, for example, as shown in FIG. 5, a plurality of blocks a to d are joined to form the hull 1.
When constructing a ship, it is necessary to weld the joint lines a' to C' between each block and the longitudinal joint lines, but this hull 1 has a height h of several tens of meters, and it is necessary to weld from inside the ship. work had to be carried out, and for this purpose it was necessary to erect a large number of scaffolds 2 within the hold. Therefore, not only does it take a great deal of time and effort to erect and remove the scaffolding 2, but the work is also dangerous as it requires work at heights.
一般に高所作業足場としては、種々提案されているが、
艙内という平面的に狭い範囲であってしかも数十メート
ルにも及ぶ高さを必要とする限られた条件のもとて使用
できる足場は見当らない。Generally, various scaffolds have been proposed for working at heights, but
There is no scaffolding that can be used in the limited area of a hold, which requires a height of several tens of meters.
本発明は前記したような従来の問題点を解決するために
なされたものであって、その目的は狭い範囲で、しかも
高所作業に適する足場とすることにより船舶建造時にお
ける船艙内の足場の架設、取外し作業を削除しもって工
期の短縮と危険作業の削減を計らんとするものである。The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to provide a scaffold suitable for work in a narrow area and at high places, thereby improving the use of scaffolding in the hold of a ship during ship construction. The aim is to shorten the construction period and reduce dangerous work by eliminating erection and removal work.

間が折れ曲がる、いわゆる中折れ可能な如く構成された
高所作業足場を提供せんとするものである。In order to achieve the above-mentioned object, the present invention provides a turntable on a truck having running wheels, one end of a first boom is pivotally connected to the turntable, and the tip of the first boom is attached to the other end of the first boom. A second boom provided with a gondola is connected to the second boom, and both the first boom and the second boom are extendable and retractable, and the space between the first boom and the second boom is bent. It is an object of the present invention to provide a scaffold for working at heights that is constructed so as to be foldable.
第１のブームはターンテーブル上に仲秋可能に固定され
てその長さ方向に伸縮可能である。The first boom is removably fixed on the turntable and is extendable and retractable in its length direction.
そして第１のブームに対して第２のブーム折れ曲がると
共に、その長さ方向に伸縮可能に構成されている。The second boom is bent relative to the first boom and is extendable and retractable in its length direction.
このようにブームが折れ曲がることによって狭い空間を
移動できると共に、延長することによって高所にゴンド
ラを揚げて作業を行うことができるのである。By bending the boom in this way, it is possible to move through narrow spaces, and by extending it, the gondola can be hoisted to high places for work.
以下第１図ないし第４図に基づき本発明による高所作業
足場の一実施例を説明する。An embodiment of a scaffold for working at high places according to the present invention will be described below with reference to FIGS. 1 to 4.

In order to align these gondolas 13 with the welding position, a device (not shown) is used to move the first boom 7 and the second boom 14 to the gondola 1.
It was operated using the operation panel provided in 3.
