Stone curtain wall is highly favoredIn recent years, with the socio-economic development and the improvement of the urban landscape, stone curtain wall is highly favored by the majority of owners and architects the in building exterior decoration, which occupies a large portion of the existing building. And the application height of the stone curtain wall is getting higher and higher, and the volume is increasing; more and more varieties of stone are used, developed from granite into ingle marble, limestone, sandstone and other varieties; looks are more and more complex, installation and construction process requirements are increasingly strict, security requirements have become more sophisticated. But domestic stone curtain wall materials market is confused, construction unit production technology lacks of technical specification, the construction workers are low quality, which bring a great deal of security risks to the project.When the architects determine the varieties of stone, they must be careful for the use of stone plates. So they have to really do good job in the following aspects:1. Carry out basic material test: compressive strength, flexural strength, flexural strength, hardness, wear resistance, frost resistance, fire resistance and machinability must meet the specifications and design requirements, and the stone used for curtain walling, should perform flexural strength test in each batch. For the regions which may have negative temperature, freeze-thaw test needs to be done. Only when the performance indicators meet the design and specification requirements, it can be used.2. Control processing accuracy of the stone, avoid secondary cutting at the construction site. Affected by the installation process, the widely used stone hanging process requires punching or slotting in the cross-section of the stone plate, so the stone thickness is limited by the installation process, a constructor thickness must be ensured. Therefore, in the process of stone plates acceptance, we must pay special attention to the thickness of the plates, the allowable deviation is +2 mm, does not allow negative difference, which should be checked block by block. 3. Avoid injury in the mining, transport, cutting and installation process, if the stone is collided after becoming a plate, the damage arising, particularly internal injuries are difficult to check out, but it will evolve over time, seriously will fracture, thus bringing security risk. We should strictly check in stone processing, transportation, installation process.4. Good protective treatment on stone surface, to ensure the dryness in the stone, and ensure that the natural stone properties unchanged.5. Single block of stone area should not be too large, metal and stone curtain wall engineering and technical specifications stipulates that it cannot be more than 1.5 square meters.www.curtainwalling.net is one of leading State-Level II enterprise in Guangzhou of China.
