1) Lifting and stacking: When lifting, nylon slings (not steel wire ropes) should be tied to 600mm at both ends of the board, with a lifting weight of no more than 2T each time. When landing, a sleeper should be placed at 600mm at each end of the board, and a dedicated person should command the lifting. The binding distance of the slings at both ends of the board should be consistent, and the slings should be straight to ensure that both ends of the board are off the ground and landing at the same time. For the convenience of transporting boards, the number of stacking layers during unloading shall not exceed two, and if conditions permit, it shall be stacked in a single layer..

2) Board quality: boards that do not meet national requirements or have unreasonable ingredients and processes without using the technology.

3) Construction management: Wall panels with less than 28 days of age should not be sent to the site for use in order to meet the construction period.

4) Moisture-proof protection: moisture-proof measures should be taken at transportation and construction sites to prevent dampness.

5) Drawing deepening: Relevant matters related to drawing deepening should be communicated with the interior wall panel company 1-2 months in advance.

Lifting Loop

1) The bottom of structural beams should have a uniform net height as much as possible to reduce the number of types of plates caused by different heights.

2) The groove treatment at the connection between the inner wall panel and the structure facilitates the hanging of the mesh and prevents cracking.

There are no irregular plates at the corners (internal and external corners), door piers, etc., and some parts need to be cast-in-place.

1) The length of the ceramic particle board wall and the ALC lightweight partition board wall are greater than 6 meters but less than 12 meters, and a structural column is set in the middle..

① The nails for corner walls and T-shaped walls must be constructed according to the drawings and connected with specialized repair materials for sheet metal..

② Try to use secondary structure pouring to complete boards smaller than 100m..

③ The installation of indoor doors is reinforced with steel sections. Doors less than 1500 are placed with 100 pieces of board and reinforced with split bolts. Doors larger than 1500 are hung with steel sections, and entrance doors are made of reinforced concrete door frames..

② Floors such as pipe wells and bathrooms that are frequently flooded should have backrests..

4) Application of partition board corner or T-shaped connection φ Fix with 6 pins. The position of the pin should be 300-400 from the top and bottom of the partition wall. The spacing between the pins is about 700. The total depth of the pin anchoring into two plates in different directions shall not be less than one plate thickness plus 150mm..

5) Due to the characteristics of ALC lightweight partition board material, it is not suitable for walls with a width of less than 200mm. Therefore, for short limb walls and door piers with a width of less than 200mm in this project, secondary structure construction is adopted, using planting reinforcement method, with 2 8mm threaded steel bars inside, and filled with C25 fine aggregate concrete..

1) Before installing the ALC lightweight partition board, the layout design must be based on the module, and ALC wall boards less than 200 are not allowed to be used;.

3) 14 days after installation, water and electricity can be used for slotting. Use professional tools for slotting, lay out the lines first, and then slotting;.

4) After the installation of water and electricity pipelines is completed, crack resistant mortar repair construction is allowed every 7 days..

5) It is best not to use ALC lightweight partition board walls for unit partition walls. It is recommended that the design institute make changes.

1) The tenon and mortise joints between the ALC lightweight partition panels are naturally interlocked, without forming deformation joints due to extrusion or adhesive bonding; After installation, the stable period should be more than one week. The decorative work of pasting grid cloth and sealing the board surface must be done by bonding alkali resistant fiberglass grid cloth at the board joints to resist cracking. The width of the grid cloth should not be less than 300mm and should be set in the center along the board joints. Elastic materials should be used for decorative construction on the surface layer.
