Description

Technical Field

[0001] The utility model belongs to the technical field of building materials, and relates to a dry-hanging board, in particular to a dry-hanging ceramic composite board and a wall dry-hanging assembly. Background Art

[0002] At present, the dry-hanging process is mainly used for the exterior wall decoration of the modeling parts or the bottom business of many public construction projects and civil construction projects. There are mainly 3 types of dry-hanging materials sold on the market: stone, metal plate, and calcium silicate board. Among them, the stone has a large self-weight, high price, obvious color difference, and is a non-renewable resource; the metal plate has a large deformation during long-term use and is extremely easy to bulge, thus affecting the aesthetics of the exterior wall; the calcium silicate board has a high water absorption rate, is extremely easy to deform after absorbing water, and its long-term weather resistance is not as good as that of the metal plate and the stone, and the mechanical anchoring risk is large.

[0003] In recent years, ceramic thin plates have begun to be used as exterior wall dry-hanging materials on the market. This kind of material has stable performance, rich decorative effects, never fades after high-temperature firing, is acid and alkali resistant, super stain-resistant, scratch-resistant, has a low water absorption rate, is frost-resistant, and the decorative effect has the same lifespan as the building. It can completely achieve the stone effect of the curtain wall, and the cost is less than half of that of the stone. However, due to the lack of toughness of the material itself, when it is subjected to external impact, it will crack or even break, thus triggering the risk of high-altitude fall.

[0004] Therefore, how to provide a dry-hanging board and a dry-hanging assembly, which adopt a ceramic thin plate while avoiding cracking or even breaking, preventing high-altitude fall, and improving the use safety, has become an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a dry-hanging ceramic composite board and a wall dry-hanging assembly. The dry-hanging ceramic composite board adopts a ceramic thin plate while avoiding cracking or even breaking, preventing high-altitude fall, improving the use safety, and being conducive to large-scale popularization and application.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In the first aspect, the utility model provides a dry-hanging ceramic composite board, which comprises a calcium carbonate backing board, a polyurethane bonding layer, and a ceramic thin plate that are stacked.

[0008] The dry-hanging ceramic composite board provided by the utility model adds a calcium carbonate backing board on the back of the ceramic thin board, and the two are firmly bonded into an integrated dry-hanging board by means of a polyurethane bonding layer. Although the calcium carbonate backing board itself has a high water absorption rate and is prone to deformation after water absorption, the ceramic thin board itself has a low water absorption rate and is very stable. Therefore, the composite integrated dry-hanging board not only solves the problem of easy deformation of the calcium carbonate backing board, but also the combination of the two avoids the phenomenon of cracking or even breaking of the ceramic thin board when it is subjected to external impact, prevents high-altitude falling, improves the use safety. The outermost ceramic thin board has rich decorative effects, is acid and alkali resistant, super stain-resistant, scratch-resistant, has a low water absorption rate, is frost-resistant, and the decorative effect has the same service life as the building, and the cost is low, which is conducive to large-scale popularization and application.

[0012] By arranging a raised structure on the bonding surface of the calcium carbonate backing board and the ceramic thin board, the utility model increases the contact area between the board surface and the adhesive, thereby enhancing the bonding strength and preventing the natural falling-off phenomenon of the dry-hanging board during long-term use.

[0013] Preferably, the raised strip structure is any one or at least two combinations of a T shape, an X shape or an I shape. Typical but non-limiting combinations include the combination of a T shape and an X shape, the combination of an X shape and an I shape, the combination of a T shape and an I shape, or the combination of a T shape, an X shape and an I shape.
