Foothold null for application of prismatic structure which accompanies

摘要

PURPOSE: To provide a construction scaffolding adaptable to cross section changes of a post-like structure by assembling two L-shaped scaffolding in square-shape and allowing the end of other side to slide on a slide rail installed to the end of each side. ;CONSTITUTION: Slide rails 3 are installed to the end of each side 1a of scaffoldings 1 formed in L shape while the end of the other side 1b of the scaffolding 1 is engaged with the slide rails 3 so that they may slide on the rails. Two scaffoldings 1 are assembled in square-shape and laid out so that they may surround a structure H. The end of the other side of each scaffolding 1 is fixed with the slide rail 3 slidably in screwed rod type. Each scaffoldins 1 is suspendingly connected to the lower and upper scaffoldigss to each other. In this case when the cross section of the structure H is changed, the screw of the screwed rod is adjusted so that the position of the end of the other side 1b may be moved so as to conform to the changes in the cross section in each direction.;COPYRIGHT: (C)1995,JPO
