Distribution bars appear in the plate, arranged on the inside of the reinforced bar and perpendicular to the reinforced bar. The function is to fix the position of the stressed steel bar and distribute the load on the plate to the stressed steel bar, and at the same time, it can also prevent cracks in the direction perpendicular to the stressed steel bar due to the shrinkage of concrete and temperature changes.

The distribution reinforcement is 90 degrees above the stress reinforcement to fix the position of the stress reinforcement and distribute the load on the plate to the stress reinforcement. At the same time, it can also prevent the shrinkage and temperature change of concrete. Cracks in the direction perpendicular to the stressed steel bars. On the shear wall, the longitudinal reinforcement and transverse reinforcement of the wall other than the wall beam and column are also called distribution reinforcement.

Gluten appears on the surface of the board.
