subject: The Stone Curtain Wall [print this page] The building curtain wall as a high-tech product technology, in the nearly 30 years of development in the increasingly mature, and with the passage of time, the upgrade of products is also growing fast. Since the reform and opening-up, China's construction industry already has undergone an earth-shaking changes, as the building curtain wall has the decorative effect of the peripheral structure, also was widely adopted to realize their own design style by architects. Stone curtain wall with its natural color and texture, shows a special decorative art effect in the building, so the development of stone curtain wall is very popular and quickly.
In recent years, with the domestic architectural designer have pursuit to construction project facade concave and convex, multiple line Angle and levels, stone material curtain wall also gradually become the first choice of architects' outside decoration materials. Therefore, a kind of stone curtain wall design scheme both an economic and safe scientific of stone material curtain wall for the development of it is very important, by my company design personnel of research and development of stone curtain wall is a new technology in many ways all have great breakthrough.
About the characteristics of traditional stone curtain wall system
1. "pin type" and "the butterfly plate" stone dry hanging system, and the upper and lower plate connect by the needle pin (or butterfly plate), simple structure and construction convenient. But interconnected the stone upper and lower plates, moving or replacement of a piece of stone plate must affect around the plate, and do not have the independent ability for replacement, for the maintenance of stone is very bad, Stone material stress point in the needle pin (or butterfly piece place), stress area is lesser, safety is poor. The installation of process, stone material need to perfusion marble glue fixed in site and do not apply to have the winter cold region construction; and By the influence of stone fixed way (calculation model), it does not apply to the large size stone plate curtain wall.
2. "back bolt type" dry hanging system, using back plug (a kind of import stone special connecting bolt) to put the stone and main structure fixed, the right material drilling equipment requirement is high, the cost is relatively high, and seismic performance is poorer.
3. The unit stone curtain wall system, adopt the aluminum alloy keel production, with a lateral frame and a floor height for basic curtain wall unit. In the workshop processing and assembly into a complete plate, then can complete installation at site. Because this system most of the work in the factory, so processing and assembly quality can be guaranteed, and overall arrangement in construction plan, reasonable arrangement, can greatly reduce the construction cycle, but because a single stone plate is in commonly 1200 mmx3700mm or so, weight is very big, to in the process of construction lifting and installation put forward high request, need special hoisting and installation of equipment. And the cost is high.
