建物取り壊し作業に於いて鉄骨を切断するための鉄骨カ
ッターに関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Object of the present invention (industrial application field) The present invention relates to a steel frame cutter for cutting steel frames during building demolition work.
（従来の公知技術）。(Conventional known technology).
軸を支点にして刃が開閉する公知の鉄骨カッターで被切
断物を切断する場合は、被切断物の抵抗によって一対の
刃には互に離れようとする力が働くのが普通である。こ
の場合一対の刃が離れると被切断物にかかる剪断力は減
少し、引張力が増大するた′め切れ味が低下し、切断に
大きな力を必要とするようになる。When cutting an object with a known steel cutter whose blades open and close using a shaft as a fulcrum, a force tends to be applied to the pair of blades to separate them from each other due to the resistance of the object. In this case, when the pair of blades separate, the shearing force applied to the object to be cut decreases, and the tensile force increases, resulting in a decrease in sharpness and the need for greater force for cutting.
このため従来の鉄骨カッターでは支点の剛度を高めると
共に両刃の隙間をできるだけ少なくして刃の分離を防止
していた。For this reason, in conventional steel cutters, the rigidity of the fulcrum was increased and the gap between the two blades was minimized to prevent the blades from separating.
しかしこの方法ではカッター本体の重量増をきたし、ま
た長期使用による支点部の摩耗により両刃の分離は避け
られない欠点があった。However, this method has the disadvantage that the weight of the cutter body increases and that the two blades inevitably separate due to wear of the fulcrum part due to long-term use.
これらの欠点に耐えて切断できるようにするためにはカ
ッターの大型化やカッター取付は台車の大型化など経済
的に大きな負担を要する欠点があった。In order to overcome these drawbacks and be able to perform cutting, the cutter must be large, and the cutter must be mounted on a large cart, which requires a large economic burden.
（本発明が解決しようとする課題）
本発明では上記欠点を除去するため切断刃の逃げを防止
し小型のカッターで効率的な切断作業が長期間行えるカ
ッターを提供せんとするものである。(Problems to be Solved by the Present Invention) In order to eliminate the above-mentioned drawbacks, the present invention aims to provide a cutter that prevents the cutting blade from escaping and allows efficient cutting work to be performed for a long period of time with a small cutter.
