EXTENDABLE BRACKET FOR SCAFFOLDING CONSTRUCTION
To provide an extendable bracket for use in constructing scaffolding at construction sites, etc.SOLUTION: Provided is an extendable bracket for scaffolding construction in which an extendable tube that can be extended and contracted in an axial direction is constructed by slidably inserting an inner tube into an outer tube. The extendable bracket includes a guide mechanism that guides the mutual sliding movement of the outer tube and the inner tube in the axial direction while preventing the inner tube from rotating in a circumferential direction, and a locking mechanism that releasably locks and secures the inner tube so that it cannot slide. The locking mechanism (21) is configured by locking and securing bolt means (29) that is screwed through the outer tube (3) so as to be freely advanced and retractable to an outer surface of the inner tube (4), The guide mechanism (20) includes a slit (22) formed in the outer tube (3) and extending in the axial direction, and a sliding piece (23) protruding from the outer surface of the inner tube (4), and is constructed by slidably fitting the sliding piece (23) into the slit (22).SELECTED DRAWING: Figure 3
【課題】建設現場等において足場を構築する際に使用する伸縮ブラケットを提供する。【解決手段】外管に内管を摺動自在に挿入することにより軸方向に伸縮自在な伸縮管を構成し、外管と内管の相互に、内管の周方向の回動を阻止した状態で軸方向の摺動を案内するガイド機構と、内管を摺動不能とするように係脱自在に係止固定するロック機構を設けた足場構築用伸縮ブラケットにおいて、前記ロック機構(21)は、外管(3)を貫通して進退自在に螺入されたボルト手段(29)を内管(4)の外表面に係止固定することにより構成され、前記ガイド機構(20)は、外管(3)に形成された軸方向に延びるスリット(22)と、内管(4)の外表面から突出する摺動片(23)を備え、前記摺動片(23)をスリット(22)に摺動自在に嵌入することにより構成されている。【選択図】図３
