Centering installation jig for rebars in a frame for seismic isolation system

摘要

PROBLEM TO BE SOLVED: A rebar having excellent rationality, work efficiency, and economic efficiency that can be re-centered on the upper and lower sides of a reinforcing bar constituting a mount for seismic isolation equipment, temporarily fixed and carried in at a target position with pinpoint accuracy. Provide a bar centering installation jig. A centering installation jig of a reinforcing bar for centering and installing a reinforcing bar forming a frame to be built on a foundation for installing a seismic isolation device, the reinforcing bar comprising a reinforcing bar And a reinforcing bar support 1 in which an upper surface plate 5 and a lower surface plate 6 in which a plurality of through holes 50 and 60 through which the reinforcing bar 7 is inserted are formed at appropriate positions The upper portion of the reinforcing bar 7 which is inserted into the through hole 50 of the upper surface plate 5 is inserted into the through hole 60 of the lower center plate 6 of the reinforcing bar support 1 and the upper centering member 2 which supports detachably in centering state. And a lower centering member 3 for detachably fixing the lower portion of the reinforcing bar 7 in a centering state. [Selected figure] Figure 3
