FITTING STRUCTURE AND FITTING METHOD FOR SCAFFOLD OF CONSTRUCTION MACHINE

PROBLEM TO BE SOLVED: To provide a fitting structure and a fitting method for a scaffold of a construction machine by which a work time and a labor at the time of fitting or removing the scaffold are decreased, and further, also the number of components can be reduced.SOLUTION: A construction machine comprises an upper revolving structure which is so mounted onto a lower traveling structure as to be capable of being revolved, and a scaffold 30 which is detachably fitted to a side wall plate 42 of the upper revolving structure in a state of being expanded outward. The scaffold 30 has an engaging pin 32 and an action point part 33 on one end side thereof. A reception part 46 which receives a force from the action point part and a bracket 43 are provided on the side wall plate side, and an engaging groove 44, which can be engaged with the engaging pin, is formed on the bracket. The engaging groove has a groove introduction part 44a which extends in a vertical direction and of which an upper end is opened, and a groove depth part 44b which so extends from a lower end of the groove introduction part as to be refracted to a side opposite to a side wall surface side. In the state that the scaffold is fitted, the engaging pin is engaged with the groove depth part of the engaging groove and the reception part receives a force from the action point part, whereby the scaffold is supported.SELECTED DRAWING: Figure 7 【課題】足場の取付時又は取り外し時の作業時間や手間を減らし、また部品点数も減らし得る建設機械の足場の取付構造及び取付方法を提供する。【解決手段】建設機械は、下部走行体上に旋回可能に搭載された上部旋回体と、上部旋回体の側壁板４２に外方に張り出した状態でかつ着脱可能に取り付けられた足場３０とを備える。足場３０は、一端側に係合ピン３２と作用点部３３とを有している。側壁板側には作用点部からの力を受ける受け部４６とブラケット４３とが設けられ、ブラケットには、係合ピンと係合可能な係合溝４４が形成されている。係合溝は、鉛直方向に延びかつ上端が開口する溝導入部４４ａと、溝導入部の下端から側壁面側と反対側に屈折して延びる溝深部４４ｂとを有している。足場の取付状態では、係合ピンが係合溝の溝深部に係合しかつ受け部が作用点部からの力を受けることで足場が支持される。【選択図】図７
