The shear wall assembly formed by the cooperation of the U-shaped steel bar group 2 and the second steel bar 3, the connection of the steel connecting piece 5 and the solidification of the concrete can reach the building strength standard.

[0053] After the shear wall assembly of a certain height is completed, the shear wall assembly is assembled layer by layer upwards.
