Grid support for hollow walls with reinforcement bars has two or more cross bars protruding alternately off-set at opposite ends to form spacer up to shuttering walls

摘要

To form a common spacer at least two (6a, 6b) of the individual cross bars are longitudinally off-set by their ends (7) so that the cross bars each protrude alternately at one of the two opposite outsides of the grid support (2) by a greater overhang (13) than at the other end. The spacer path (p) projected vertically on an imaginary extension (e) of one of the two cross bars defines the space for the shuttering walls (11) or the wall thickness of the hollow wall.
