Cost for curtain wall structure

Glass curtain wall mainly has five structural forms, usually, when the use of materials, curtain wall height, wind load size, glass plate size is similar, the unit price of open frame per square meter is lower than half hidden frame glass curtain wall, the difference between open frame and hidden frame can reach 10-20%, the difference between half hidden frame and hidden frame is about 5-10%. Curtain wall height more than 12m full glass unit price is mostly higher than the point support type, among which the hanging type full glass curtain wall unit price is the highest, even as high as 3000 yuan /m2, because the glass plate thickness is large, the unit price is very high; The supporting structure of point supported glass curtain wall can be divided into plane structure system and space structure system. Plane structure system mainly includes beam system, I – frame system and arch system. When the height is too high, the economy of the beam system is poor, too heavy. The frame system is a structural form used by large public buildings. It can be done very high, about 1000-2000 yuan /m2. But when the span exceeds 80~100m, the economic benefit of arch system is more significant.

Of course, compared with curtain wall structure, the mechanical properties of space structure are much more reasonable. At present, the curtain wall structure can consider adopting spatial structure form of the general space truss structure, net shell structure and cable structure, spatial structure system to enhance the lateral connection, the structures of an organic structure as a whole, not only eliminates unnecessary transmission layer of repeated load, and the internal force distribution more uniform in the curtain wall supporting structure, therefore, This kind of structural system not only has good economy, but also has large stiffness and good seismic performance. Now there are experts combined with many years of curtain wall engineering design and construction experience, design a set of intelligent “hook type” curtain wall system. The system combined with the characteristics of the aluminum itself to optimize the design, complete series, easy to choose.
At the same time it reduces unnecessary consumption, compared with the traditional component curtain wall aluminum saving 20%, compared with the unit curtain wall aluminum saving more than 40% L, saving labor costs about 10~ 15 yuan/square meter.
Curtain wall structure is one of the most important factors affecting the cost.
The influence of the variety and specification of the materials used on the cost
The variety and specification of materials used is another important factor affecting the cost of curtain wall. On the basis that physical properties meet functional requirements and mechanical properties ensure structural safety, more economical materials should be selected. Standard flat glass should be used as far as possible, if the use of arc type hot bending glass will increase the cost of the project. Similarly, using larger unit sizes or thicker glass also increases the project cost.
