➤ Key points of finished product protection · no collision within 7 days of installation· The walkway wallboard shall be protected from impact damage (external corner)· Mud and dust on the wall to prevent pollution (hydropower discipline)
.
Design key points: set tongue and groove at the connection between main structure and wallboard· The layout shall be reasonable and the cutting board shall be minimized (the positioning of long wall structural column shall be confirmed by the wall board manufacturer)· Eliminate the structural connection of special-shaped wall; 2
.
Performance requirements of special mortar · compressive strength ≥ C15 · bonding strength ≥ 0.7MPa · flexibility ≥ 1.0mm4
.
Wallboard performance · drying shrinkage value 3
.
No plastering, high efficiency! How is the new process “prefabricated inner wall panel” constructed? Compared with the traditional masonry wall, the prefabricated inner wall panel has many advantages, can realize no plastering, reduce the common quality problems such as hollowing and cracking, and has fast construction speed, less restricted by climatic conditions, saves labor and improves the construction quality

Disturbance after installation is strictly prohibited· Joint filling: the bottom joint must be washed with water before joint filling, and the joint filling must be dense and filled twice· Wooden wedge: the wooden wedge must be taken out after an interval of 7 days, and it is forbidden to disturb in advance; ➤ Key points of hydropower installation process · marking acceptance: prevent wall panel damage caused by large-area slotting· Cutting and chiseling: brutal and violent construction is prohibited· Mortar repair: dense backfilling and smooth repair
.
➤ Anti cracking measures 1
.
Construction requirements · waterproof inverted sill strength (C20) for wallboard construction· The vertical joint of wallboard shall be installed by squeezing mortar to ensure full mortar and full joint· Grout the bottom joint of wallboard after cleaning the ground to ensure stable mortar connection· The technical intermittence of each process meets the installation requirements, and it is forbidden to disturb in advance· Accurate positioning of water and electricity to prevent wall panel damage caused by large-area slotting· Special tools must be used for wall panel slotting, and rough and violent chiseling is strictly prohibited..

Now let’s take a look at the country garden project to see how the prefabricated inner wall panel is constructed
Therefore, prefabricated interior wall panels have been widely accepted and applied by the industry, especially large real estate enterprises such as Vanke and country garden have included the application of this technology in the enterprise standard
