Source: Porcelain backslapping of urban residential buildings is an important facade design technique of Prefabricated building.
Through the refined design of backslapping of porcelain panels and continuous process improvement in practice, the quality of building facades has been significantly improved.
The key points of reverse printing design for porcelain plates are that during the production of prefabricated components, the selected ceramic tiles or stones are poured together with concrete in the factory and formed as a whole (see Figure 1).
Compared to the dry hanging or wet sticking process, the reverse printing process has a smooth and flat surface, precise positioning, and firm adhesion, which can effectively avoid problems such as frost heave and aging.
Figure 1 Porcelain plate reverse striking technology The reverse striking technology mainly uses small ceramic tiles (see Figure 2, left), but due to the limitations of the process, it is not suitable to use in large areas in the north.
As the reverse striking process continues to mature, the size of reverse striking facing materials continues to increase.
In Japan, where Prefabricated building technology is leading, it has been possible to reverse strike large stones (see Figure right).
Figure 2: Early Japanese anti ceramic tile construction effect (left) Recent anti stone construction effect (right) Many exterior walls of buildings use stone as anti ceramic materials.
Although stone has a good appearance, there are problems such as insufficient acid and alkali resistance, high expansion rate, and unstable bonding strength with concrete, and different stone textures differ greatly, which greatly increases the difficulty of production.
Therefore, the porcelain plate with more stable performance has gradually become the first choice for reverse decoration of Prefabricated building.
Application Technology Planning of Porcelain Plate Reverse Printing Technology: Compared with dry hanging veneers, once modified or damaged, the cost of replacement is much higher than that of dry hanging veneers, and even cannot be replaced.
Therefore, at the beginning of the design, technical planning should be carried out in conjunction with architecture, structure, mechanical and electrical specialties to determine the principles related to the building facade.
The basic module of modular collaborative architecture is the basic data principle for determining the size of decorative surfaces.
Generally, the type of ceramic panel size is relatively single, and improving the modular design of building facades will effectively improve the utilization rate of ceramic panels and reduce economic waste; On the other hand, building modules with similar sizes will also make the facade more organized and aesthetically pleasing.
Therefore, at the beginning of design, architects should combine architectural, structural, mechanical and electrical disciplines in multiple dimensions such as plane, facade, and section, establish common design principles, and uniformly plan the plane bay, building floor height, component dimensions, door and window openings, and mechanical and electrical reserved openings to avoid losses caused by later modifications.
Collaborative prefabricated component size is the foundation for affecting the size of ceramic panels
