[0002] With the development of prefabricated buildings, green building materials have also emerged. Gypsum-based partition walls have the characteristics of high flatness, light weight, fire resistance, and heat insulation. At the same time, due to its advantages such as prefabricated cable troughs, economic rationality, convenient construction, and green environmental protection, it is gradually widely used in the field of prefabricated decoration.

In the application of long panels, the main problem is that the gypsum board itself is not strong. The bending bearing performance of the board becomes worse after the lengthening, which makes it easy to break when carrying and lifting the board, bringing inconvenience to the application; at the same time, the prefabricated wire troughs and holes on the gypsum board make its strength worse, and it is even more necessary to improve the strength of the board; on the other hand, traditional gypsum boards do not have waterproof functions, which limits the application of partition wall panels and cannot be used in humid environments such as bathrooms and basements.

[0025] Specifically, the first mounting groove 11 is a U-shaped groove, and the second mounting groove 12 is a circular groove. The first mounting groove 11 is for pre-buried pipelines, and the second mounting groove 12 is for reducing the weight of the gypsum body 1, so that the gypsum board has its own wire grooves and weight-reducing holes. Multiple second mounting grooves 12 are equidistantly arranged, and the second mounting grooves 12 can reduce weight and absorb sound. The diameter of the first mounting groove 11 is smaller than the diameter of the second mounting groove 12, thereby achieving the goal of reducing the weight of the gypsum body 1 while ensuring the strength of the side end of the gypsum body 1. First, the first installation groove 11 and the second installation groove 12 are respectively opened on the gypsum body 1, and then the waterproof structure 3 is set on the outer surface of the gypsum body 1, that is, the first fitting waterproof part is fitted at the first installation groove 11 of the gypsum body 1, the second fitting waterproof part is fitted at the second installation groove 12 of the gypsum body 1, and the third fitting waterproof part is fitted on the other parts of the gypsum body 1 except the first installation groove 11 and the second installation groove 12, and the third fitting waterproof part is connected to the first fitting waterproof part and the second fitting waterproof part respectively, and the first fitting waterproof part, the second fitting waterproof part, and the third fitting waterproof part can be integrally formed.
