（産業上の利用分野）
本発明は電柱、コンクリート柱、煙突等の先端が先細り
と成る錐体状構築物での高所作業や解体作業をするをす
るための作業装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention is a working device for performing work at heights and demolition work on cone-shaped structures with tapered tips such as utility poles, concrete poles, chimneys, etc. It is related to.
（従来技術及びその問題点）
従来電柱、煙突などの錐体状構築物の解体方法の主なも
のとして、
先ず木を切り倒すときのように対象構築物の下部を切り
壊して倒す技術が上げられるが、この方法によるときは
倒れる上部の長さ分の敷地の広さが必要であるというこ
とと、倒れる方向もあまり正確にだすことが出来ず危険
である等の欠点が有る。(Prior art and its problems) The main conventional method for dismantling cone-shaped structures such as telephone poles and chimneys is to first cut down the lower part of the target structure like when cutting down a tree. This method has disadvantages, such as requiring a site that is as wide as the length of the top of the tree that will fall, and that it is dangerous because the direction in which it will fall cannot be determined very precisely.
又他の方法として対象構築物の周りに下から丸太か単管
パイプのような足場材を組み上げて、その周りに部材、
道具、かすなどの墜落防止にシート囲いをし、壊したか
すは上部よりダクトシュートにより下方まで降ろしなが
ら解体していく方法が有るが、この方法では足場材の組
み立てや、解体した単管の撤去作業をしなければならな
いので、足場材などの落下の危険や、組み立て、解体の
労力が極めて困難である等の欠点が有る。Another method is to assemble scaffolding materials such as logs or single pipes from below around the target structure, and then build materials around it.
There is a method of enclosing tools, debris, etc. with a sheet to prevent them from falling, and disassembling the broken debris by lowering it down from the top through a duct chute, but this method involves assembling scaffolding materials and removing dismantled single pipes. Since the work has to be done, there are disadvantages such as the danger of scaffolding materials falling, and the labor involved in assembling and disassembling them is extremely difficult.
更にタワー車を利用して対象構築物近辺まで行き作業す
る方法もあるが、タワー車の入れる敷地が必要であるこ
と、高さとか作業面等の作業範囲が限定されること、力
をいれて作業が出来ない等の欠点が有った。Furthermore, there is a method of using a tower vehicle to go to the vicinity of the target structure and work, but it requires a site where the tower vehicle can fit, the work area is limited in terms of height and work surface, and it requires effort. There were drawbacks such as not being able to.

したものである。Although methods have been adopted in which the above-mentioned techniques are used in combination, the above-mentioned drawbacks have not been solved.11゜(Means for solving the problems) The present invention solves the above-mentioned drawbacks Utilizing the structure of structures such as telephone poles and chimneys that gradually become thicker from the top to the bottom, the inner surface of the frame-shaped workbench is tightened to the outer surface of the structure to prevent accidental work of the workbench. It is designed to allow work such as dismantling a structure from the top down while preventing it from descending.

The surfaces can be connected freely, and the clamping rod is arranged to protrude and adjust freely inside the enclosure so that it can be pressed against the conical structure, so it is easy to place the clamping rod in high places during demolition work such as chimneys. It can be installed horizontally while being adjusted, and since the cone-shaped structure gets thicker toward the bottom, the tightening rod does not spread out, so it is safe and will not fall accidentally. By gradually widening the clamping rods, the support frame etc. will naturally lower due to its own weight, and by simply adjusting the clamping rods by operating the operating mechanism, the workbench can be set horizontally, allowing you to proceed with the next work. can be easily prepared.
