SCAFFOLD Russian patent published in 2005 - IPC

FIELD: building, particularly to perform construction-and-assembling and finishing works.

SUBSTANCE: scaffold includes vertical posts with fixed support rings, and tubular longitudinal and transversal tie members. Vertical posts, tubular longitudinal and transversal tie members are attached one to another by support ring, fork member and wedge-like means. Support ring is made as a cup with thickened walls having rounded edges with radius depending on load value. Cup bottom is formed as a plate with curved edges extending at an angle to cup axis or symmetry. Initial point of curved plate edge is spaced from inner cup wall. Through vertical cut is formed in cup bottom for wedge-like means securing. Wedge-like means is made as hollow cone having fixing finger on lesser cone base. Fork member for attaching longitudinal and transversal tie members is made as a single unmatched upper gripping means inserted in support ring cup and shaped similarly with cup outline.
