Background
After the modern reinforced concrete structure emerges, the brick wall loses the bearing effect and is replaced by other filling materials more. Due to the pursuit of the effect of the traditional brick wall and the pursuit of light and thin requirements for adapting to modern facing materials, the face brick which is exactly like the effect of the brick surface but has thinner thickness appears. The face brick has various specifications, in particular to an indoor decorative brick. With the development of technology, face bricks generally have the tendency of being larger, more vivid in patterns and more in forms.
The conventional bonded type wall tiles have some fatal disadvantages due to their own structural defects such as: the specification cannot be too large, and the falling risk is greatly increased if the specification is too large; when the face brick is used for outdoor wall surfaces, due to long-term rainwater soaking and multiple freeze-thaw cycles in winter, the face bricks are easy to peel off from joints, and the safety of personnel is seriously influenced; the construction method is too dependent on manual construction, the labor intensity is high, and the quality is not easy to control, so that more potential safety hazards are brought. Due to the improvement of energy-saving requirements, most buildings adopt an external heat insulation structure, so that the external wall face brick pasting is more limited.
In order to adapt to the structural characteristics of the modern external wall external thermal insulation and meet the requirements of a modern construction system which is simple and convenient to construct and easy to control the quality, a dry-hanging porcelain plate system is produced. The dry-hanging porcelain plate system is similar to the principle of a stone slab curtain wall, and the supporting system and the panel of the dry-hanging porcelain plate system do not bear the load of a main body structure. Besides the safety guarantee, the system has the obvious advantage of improving the thermal performance and sound insulation performance of the wall body.
For domestic common shear wall structure high-rise houses (the specification requires less than 100 meters), a point-hanging type curtain wall structure is usually adopted for installation due to high wall strength. The point-hanging type curtain wall structure is a system in which a panel is directly in point-type connection with an outer wall structure through a hanging piece. The biggest advantage of the point-hanging curtain wall structure is that metal beams and vertical columns in common curtain wall systems are saved, the construction is simpler and more convenient, the thickness of the curtain wall is reduced, and the point-hanging curtain wall structure is economical and efficient. However, the point-hanging curtain wall structure has low safety of the porcelain plate due to small contact area of connection, and safety accidents are easy to happen.
