TUBULAR MULTITIER SCAFFOLDING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: scaffolding is used for construction and erection operations. Tubular multitier scaffolding has sectional vertical posts connected to each other by cross-members in the form of frames, joining units connected with posts, wooden decking mounted on cross-members, struts and screw-type jacks with step bearings, in which each joining unit is made in the form of tubular catcher installed inside one of end-faces of post with circular clearance and pivotally secured with possibility of deviation in vertical planes. Wooden decking is made as double-strip. Strips of decking are connected to each other by means of pivoted units. Along end-faces they have metal trimming with through-slots. Their axes are located at angle with respect to lateral axis of trimming. Cross-members are made with vertical pintles located in through-slots of trimming of decking strips. Joining units are made with pivoted joining members and are adapted for angular and linear displacement. Cross-members are made with vertical pintles seating in trimming slots. They create load-bearing contour at lateral displacement of decking strips. Aforesaid embodiment of scaffolding is simple in design, requires less metal to manufacture and can be assembled and disassembled at construction site. EFFECT: higher efficiency. 6 cl, 10 dwg
