[0002] As an energy-saving material, ALC boards are gradually being widely used in the construction of filling walls in large venues. During the construction process, ALC boards are installed vertically row by row, with connectors used to fix the upper and lower ends of the boards and adhesives used to bond them horizontally into a whole. When a position for an electric box needs to be reserved in the middle of the board, most of the time a hole is reserved on the board, and then the electric box is installed in the reserved hole. During construction, the ALC board is prone to cracks due to the dense wire pipes around the electric box and the low strength of the ALC board itself. Summary of the invention

[0003] In view of the above problems, an embodiment of the present invention provides a construction method for reserving an electric box applicable to an ALC panel.

For example: there are four types of electric boxes with 5, 6, 9, and 10 wires on site. When prefabricating special ALC panels, we produce wall panels with two specifications of 6 and 10 pre-embedded electric pipes. By reducing the specifications of the wall panels, we can reduce the difficulty of panel processing and on-site construction.
