Curtain wall appearance patent

The upgrading of curtain wall product structure and the acceleration of technological innovation. After decades of development, the functions and material sources of curtain wall products are constantly enriched, especially with the development of new materials and continuous innovation of technology, building curtain walls are gradually developing in the direction of energy saving, environmental protection and intelligence, and new products such as double-layer curtain walls and photovoltaic curtain walls enter the market. ?

Building curtain wall enterprises must have design qualification certificate, production license and construction qualification certificate. Capital barrier, the building curtain wall industry is a capital-intensive industry, with long construction period, difficult repayment and large capital demand, which is a big obstacle to enter the industry.

Precautions:

Hidden frame curtain wall and semi-hidden frame curtain wall usually adopt pressure plate (pressure block) to transmit force, and the distance between them is generally not more than 300 mm There are two kinds of fixed-distance and non-fixed-distance pressure plates. After the distance between the pressure plate and the connecting bolt is tightly fixed, the pressing gap is relatively fixed, and the pressing force on the sub-frame of the glass panel is relatively consistent, which is convenient to absorb the deformation of the structure and temperature, reduce the friction noise, and avoid the image distortion of the glass panel caused by uneven pressing of the press block.

False open frame usually adds a decorative strip at the joint of hidden frame curtain wall to achieve the decorative effect of open frame curtain wall. The structure should adopt the design method of hidden frame curtain wall to design insulating glass and structural adhesive, that is, the second sealant is sealed with silicone structural adhesive. If polysulfide glue is used as the secondary seal of insulating glass, it may not be damaged by ultraviolet rays, but there are still unsafe factors.
