Claims

[Scope of utility model registration request]

When the main reinforcement of a beam in reinforced concrete construction is arranged in two stages, the overlapped reinforcement spacer is used to maintain an appropriate gap between the upper main reinforcement and the lower main reinforcement at the bottom of the beam. A recessed upper support part, a lower mounting part recessed downward so as to rest on the lower main reinforcement, and a connecting part that connects these upper support parts and lower mounting parts vertically at a predetermined interval. Two main reinforcement spacing holding parts consisting of are arranged so as to face each other at a distance,
At least one of the two legs extending from both sides of the lower placement part of one main bar spacing holding part is connected to a corresponding leg of the other main bar spacing holding part by a connecting part to maintain main bar spacing. A stacked bar spacer characterized in that a mounting part recessed downward for placing on the auxiliary bar is provided in the middle of the connecting part of the parts.
