When the United States uses stone as the exterior finish, there are different processes such as polishing, polishing, flame singeing, chiseling, and axe. In the architectural art, using different combinations of techniques has become a new trend in the development of architectural stone decoration. For example, in the decoration project of the Bank of China Building in Hong Kong, the same face is made of the same stone, and the two surface treatment methods of polishing and flame singeing have achieved a good artistic decoration effect.
In the United States, the granite exterior finish is installed by dry hanging method, but also by the method of glue sticking, but the process of sticking cement mortar is not used, so the phenomenon of large color difference and face is not found. Regardless of the dry hanging operation or the pasting process, all the stone board joints are made of silicone rubber joints, and the general seams are wide (5-10MM).
In the United States in recent years, a large number of prefabricated outer panels with granite finishes have been developed for use in reinforced concrete frame structures and steel structures. The size of the siding is also increasing, with a maximum length of 9CM. The siding is generally located on the floor. The exterior wall panels with granite finishes are prefabricated and shipped to the site for installation. With this process, it can be molded once in the factory, not only with good quality, but also with high efficiency, which greatly improves the level of mechanization and factory. Practice has proved that this method of façade with outer facing, structural layer, waterproof and heat preservation is worthy of popularization and application. Although it was vigorously promoted in Beijing in the 1980s, it was rarely used in the 1990s. In addition, foreign exterior wall finishes are less tiled (especially white bricks).
Even if the tiles are used, bricks resembling brick walls with similar color dimensions to clay bricks are used. Stones (including granite and marble) are also used in interior decoration in the United States. The ground granite facing is multi-slotted with a slit width of 5-10MM and seamed with silicone rubber. Many floors use fine-grained granite, which is not only non-slip, but also has a good foot feel when walking. In addition, in some important public buildings in the United States, white stone similar to Chinese white marble is used as the exterior wall finish. Generally, the stone with fine surface is very beautiful. The size of the stone can be large or small. Silicone rubber joints.
The large halls, halls, and entrances of some large public buildings in the United States are designed with large-diameter cylinders. These cylindrical finishes generally use colorful stones, some of which are as high as 8-9M, and it is difficult to find seams. The use of stone for artistic sculpture is also common in foreign countries, especially in some important large-scale excursions.
In short, from the development trend of the international architectural decoration industry in recent years, the glass curtain wall has been decreasing, and the stone finish is broken. From the point of view of stone veneers, in reinforced concrete frames or steel structures, there are more prefabricated sidings with exterior walls with stone veneers. In the architectural art technique, the matte stone and the polished stone are used together, which has the decorative charm of stone.
