On The Stone Wall Material Selection And Construction Considerations
In recent years, with the socio-economic development and urban landscape improvements in Building External decoration, stone wall of the wide favor of owners and architects, in the existing building has been occupied a large proportion. And the application of high stone walls rising, an increasing body mass; use more and more varieties of stone, from a single Granite Developed to marble, limestone, sandstone and other varieties; modeling increasingly complex requirements on the installation of the construction process more strict on the security requirements have become more sophisticated. But the domestic market chaos stone curtain wall materials and construction units lack technical specifications of production technology, construction technology low quality personnel, which gave Project Great security risk. For various reasons, stone plates, hanging plastic, dry pendant selection and pre-(post) embedded parts of the production and installation is easy to ignore, and this paper, four kinds of material that a brief analysis on how to choose.
Stone plate As the external structure of the stone wall, it does not bear the main structure of the load, but it is in the outer surface of the building, except to bear its own weight, but also to withstand wind loads and seismic effects and temperature changes, so asked Stone to be safe and reliable. On the stone’s performance, quality requirements include: compressive strength, flexural strength, flexural strength, hardness, wear resistance, frost resistance, fire resistance, machinability and so on.
Stone curtain wall of stone is natural selection, the exploitation of natural stone from the mountain down the importance of performance depends on its mineral composition and structure, but the series out of sample performance tests, each specimen were different, as industrial products as different as the small. As drawn the different surface, the measured performance is also not the same.
Above, when the architect to determine stone varieties, the use of the stone panels must be careful to do good work in the following areas:
1, do the basic material test: its compressive strength, flexural strength, flexural strength, hardness, frost resistance, fire resistance, machinability, etc. must meet the specifications and design requirements, while stone for the walls, each batch should be bending strength test. On the possible negative temperature for the area, freezing and thawing test needs to be done. Only when the design and performance specifications are met before the use.
2, control the precision of stone, to avoid the second cut at the construction site. By the installation process of, now commonly used stone hanging process required cross section in the stone plate hole or slot, the thickness of stone limited by the installation process, must ensure that the thickness of a structure, so the process of acceptance when the stone plate Special attention Plate The thickness, the allowable deviation +2 mm, does not allow negative difference, to by-block inspections.
3, in the mining, transport, cutting and installation process to avoid injury, Stone has become the board if it is collision damage arising from internal injuries in particular, it is difficult to be detected, but it will evolve over time, serious would be the fault, leading to potential safety problems. In stone processing, transportation, the installation process should be strictly.
