4.
Door openings greater than 1500 shall be hung with section steel, and door entry doors shall be reinforced concrete door frames.
I.
The pin position should be 300 ~ 400 away from the top and bottom of the partition wall.
The pin spacing is about 700.
When deepening ALC light partition board, communicate with the design institute and consider using solid bricks for construction.
Corner or T-shaped treatment method 5) due to the material characteristics of ALC light partition board, it is not suitable for walls less than 200mm wide.
5) It is better not to use ALC light partition board wall for unit household wall, and it is recommended that the design institute change it 4.
For decoration, the alkali resistant glass fiber grid cloth must be bonded at the plate joint to resist cracking.
1) the length of ceramsite plate wall and ALC light partition wall is greater than 6m, If it is less than 12M, the structural column shall be set in the middle.
It is believed that ALC light partition board will have broad development prospects and will be vigorously promoted after gradual improvement.
The total depth of the pin anchored into two plates in different directions shall not be less than the thickness of one plate plus 150mm.
Elevation of distribution box Treatment measures 1) Special shaped plate shall be made for the distribution box and embedded in the special-shaped plate; 2) It is strictly prohibited to slot and bury the distribution box after the wall panel is installed; 3) The distribution box shall be embedded and reinforced in the plant; If it cannot be embedded and installed in the factory, it must be embedded and installed on the site before the wall panel is installed (on the wall).
6.
4) Application of corner or T-connection of partition board φ 6 pin fixing.
