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.
2.
In order to facilitate the transportation of plates, the number of stacking layers during unloading shall not exceed two, and when conditions permit, they shall be stacked in one layer.
During hoisting, special personnel shall be assigned to command, the binding distance of sling at both ends of the plate shall be the same, and the sling shall be smooth and straight to ensure that both ends of the plate are off the ground and landing at the same time.
4.
ALC light partition board, also known as autoclaved aerated light concrete board, which is a new building energy-saving product.
3) The water and electricity can be slotted 14 days after the installation is completed.
5.
The pin spacing is about 700.
4.
2.
[optimization direction] 1) the clear height of the structural beam bottom shall be unified as far as possible to reduce the number of types of plates due to different heights.
After the wall has stood for at least 7 days, the wood wedge shall be removed and the bottom 1:3 cement mortar shall be filled.
4) Crack resistant mortar repair construction is allowed at an interval of 7 days after the installation of water and electricity pipelines.
3.
When making wallboard, due to the thin plate, the building use area is expanded.
ALC light partition board layout, slotting, notch width is unlimited, and the depth should not be greater than 1 / 3 of the plate thickness [treatment measures] 1) before the installation of ALC light partition board, the layout design must be carried out according to the modulus, and ALC wall board less than 200 shall not be used.
The top node of pipe clamp construction (Fig.
2) If there is a painting layer, it is recommended to use gypsum mortar for painting, which has small shrinkage and reduces the risk of wall cracking.
Conclusion the new process of ALC light partition board should deeply consider each process from perfection to construction, and systematic and comprehensive measures must be taken to solve it.
