Novel steel bar protection layer thickness control device

A novel steel bar protection layer thickness control device is characterized in that a steel bar cage is formed by binding or welding transverse steel bars and vertical steel bars, H-shaped steel is arranged on the outer side of the steel bar cage to reserve a space for pouring a steel bar protection layer, angle steel is used for limiting the thickness of the steel bar protection layer, and scalesteel bars are used for controlling the thickness of the steel bar protection layer. The positions of the scale steel bar and the angle steel are fixed through the position of the long steel bar, thefastener controls the scale steel bar and the cross-shaped positioning cylinder to enable the scale steel bar and the cross-shaped positioning cylinder to move relatively or not, and the short steelbar limits the range of the rotating area of the cross-shaped positioning cylinder around the long steel bar; the long steel bars penetrate through the transverse holes of the two cross-shaped positioning cylinders, the two end
