As we all know, China is a big country in stone consumption and production. For example, we know that luxury hotels and villas cannot be decorated without natural stone. What about developed America? What is the development of stone decoration in America? Next, Topteck Stone Group will tell you some development trends of stone decoration in the United States.
In recent years, the United States has used more granite as exterior decoration. Before, it was more polished granite, and gradually developed to rough granite, which is also to meet the needs of aesthetic art. Generally speaking, the rough granite does not reflect light, the color is very uniform, and there is no color difference, giving people a sense of comfort.
However, the rough surface of the United States is not the same as the traditional rough surface of our country, which is chiseled by stone workers, because this kind of rough surface can not reflect the color and effect of its granite. The rough granite in the United States is first cleaned and polished, and then burnt with flame to form a singeing board, so the cost is high. It has been widely used in some new construction projects in the United States. Most of the granite exterior finishes are mainly rough granite, and polished granite is only used as a foil, but some projects are the opposite.
The method of granite processing in the United States is to first polish the same granite block by block, then cover the part to be polished with a high temperature resistant rubber layer, and finally process the part to be polished with flame. The results are both ideal. Granite facing in the United States not only has good color configuration, but also has very small color difference. Most of the stones are imported, and the cost is high. In addition, there are different processes such as polishing, polishing, flame singeing, chiseling, and chopping axe. In terms of architectural art techniques, different process combinations have become the new trend of architectural stone decoration.
For the installation method of granite exterior facing, the dry hanging method is often used in the United States, and the adhesive bonding method is also used, but the cement mortar bonding process is not used. Therefore, the phenomenon of large color difference and large face has not been found. All stone slab joints, whether in dry operation or by pasting process, shall be pointed with silicone rubber, and the joint width is generally 5 to 10mm.
In recent years, the United States has used a large number of prefabricated exterior wall panels with granite facing in reinforced concrete frame structures or steel structures. The size of the wall panels is also increasing, with the maximum length of 9m. The installation methods of the wall panels are generally located on the floor. The exterior wall panels with granite facing are prefabricated in the prefabrication factory or on site, and then transported to the construction site for installation. This process can be formed in the factory once, which is not only of good quality, but also of high efficiency, The level of mechanization and industrialization has been greatly improved. Facing bricks (especially white facing bricks) are seldom used for exterior wall facing in the United States. Even if facing bricks are used, they are similar in color and size to clay bricks.
What about American interior decoration? Of course, stone is also used in American interior decoration. In addition to granite, marble is also widely used. Most of the granite facing on the ground is divided into joints with a width of 5 to 10 mm, which are pointed with silicone rubber. There are many granite floors, all of which are made of granite with fine wool surface, which can prevent slipping and have a good feeling when walking.
In some important public buildings in the United States, white stones similar to white marble are also widely used for exterior wall facing. Generally, fine stones are used, which are very magnificent and beautiful. The stones can be large or small in size. The abutments are also pointed with white silicone rubber. A large number of diameter columns are used in the design of the vestibules, halls and entrances of some large public buildings. These columns are decorated very carefully. Generally, colorful stones are used. Some of them are as high as 8 or 9 meters. Surprisingly, no seams can be seen. In addition, stone is also widely used as art sculpture in the United States, especially in some important, large-scale projects for everyone to visit.
According to the development trend in recent years, the decoration of glass curtain wall in the United States has been relatively reduced, and the stone facing has gradually increased. From the perspective of stone facing, in frame or steel structure buildings, there are more exterior wall precast panels with exterior wall stone facing. It can be seen that, whether in China or abroad, natural stone is deeply loved by people for architectural decoration.
