Wall slotting
After measuring and determining the height, slot the wall. Slot 5 cm first, then punch 8- 12 cm.
Template installation
Install the template. More support, not concave and convex. 10 square meter or more, and the height should be increased by 1%.
Slotted drilling
Drill holes in the box. Every 12cm, drill an electric hammer hole of 14cm. After drilling, use automatic hole cleaner or manual hole cleaner to clean the debris and ash in the hole, and then plant reinforcement.
Steel binding
Binding reinforcement: main reinforcement number of national standard reinforcement. 12, auxiliary reinforcement number. 10, double-layer bidirectional, and the spacing is not more than 200mmX200mm. The concealed beam reinforcement is. 16, and the exposed beam reinforcement is No.20, and it is better to add beams over 20 square meters. Stairs should have beams. (Consider wiring pipes to facilitate wiring in the future. )
concrete pouring
Pouring concrete: In order to ensure the quality of cement, stones should be washed clean, and medium-coarse yellow sand should be used as much as possible. Vibrating concrete: the vibrating rod and plate vibrate to flatten the surface. The thickness of cast-in-place surface after finished product shall not be less than 10 cm. Above 20 degrees Celsius, water and maintain it every day, and dismantle it after 8 days. 15 degrees below water conservation once every two days, 15 days after the template can be folded. In this way, the cast-in-place surface and the original wall become a whole, bearing 300 kilograms per square.
