Steel bar metering and storing device for engineering construction

The invention discloses a steel bar metering and storing device for engineering construction, relates to the technical field of steel bar metering and storing, and aims to solve the problem that manual end alignment adjustment and manual counting are required when steel bars are positioned on a bracket. The turnover plate is installed at the top of the storage rack, waterproof protection of reinforcing steel bars in the storage rack can be completed, blanking buffering of the whole section of cut reinforcing steel bars can be completed through the turnover plate and the material receiving barrel on the rotating rod, the situation that the storage rack is damaged by the directly-falling reinforcing steel bars is avoided, and meanwhile the position of the sliding plate in the storage rack can be adjusted by rotating the rotating wheel; the steel bar storage rack is more flexible and convenient to use, a rotating rod is used for receiving and discharging the steel bars, a rotating column located on a placing blo
