Rebar Cage building and defense: most sensible Practices offers instructions for the secure dealing with of metal reinforcing-bar (rebar) cages through the layout, fabrication, and erection method. the point of interest is on rebar cages used for giant, cast-in-place concrete columns in numerous settings, together with bridge piers, increased street sections, and high-rise structures. those cages are inherently volatile, often held jointly by way of tie-wire on my own. they're tough to manufacture, to boost from the horizontal to the vertical place, and to aid within the transitority until eventually concrete is solid. Engineered transitority help structures, akin to bracing or cable-guy platforms, can mitigate the instability of status rebar cages and withstand lateral a lot, making sure greater defense for the iron employees tasked with hiking the cages.
Topics comprise: evaluation of rebar cages; organizational administration for rebar cages; development engineering; checklists of most sensible practices for development; and precis, conclusions, and recommendations.
This quantity describes most sensible practices for development engineering and building perform concerning rebar cages. will probably be invaluable to development engineers operating with huge columns for the 1st time in addition to development contractors trying to determine guidelines and techniques regarding rebar column safety.
