In this embodiment, as shown in fig. 5, the gypsum veneer 300 is used as a wall member plate and is fixedly assembled with the inner side keel frame, a layer of gypsum slurry is sprayed first to form a priming slurry layer 100, and then the sprayed gypsum composite slurry is piled layer by layer from bottom to top to form a gypsum composite slurry layer 200, after the gypsum is sprayed and solidified into a wall body for two times, the gypsum veneer 300 does not need to be dismantled, and the gypsum veneer 300 can play a role in interior decoration.
In the three embodiments, gypsum slurry is adopted for priming, the process has the unique advantages that the gypsum slurry has strong binding power, can effectively prevent perlite in the gypsum perlite composite slurry from colliding and bouncing with a support template or an insulation board or a gypsum veneer, has good affinity with the gypsum perlite composite slurry, and can effectively avoid the phenomena of stripping, hollowness, uneven compactness and the like between the sprayed gypsum perlite composite slurry and the support template or an inner insulation board or the gypsum veneer.
It should be noted that the above description is only a preferred embodiment of the present utility model, and the present utility model is not limited to the above embodiment, but may be modified without inventive effort or equivalent substitution of some technical features thereof by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
