Classification of artificial panel curtain wall

Architectural decorative curtain wall is an architectural curtain wall installed on other walls, located in the outdoor space, the inner surface does not contact with the indoor air, and mainly plays an external decorative role. As non-transparent curtain wall, artificial plate curtain wall is mainly applied in the form of decorative curtain wall with solid wall behind:
(1) Open curtain wall: the decorative layer of exterior wall with ventilation on the back, that is, the joint between curtain wall plates does not take sealing measures and does not have airtight and watertight performance of the curtain wall building. Open curtain wall includes: open seam type, plate seam shelter type, plate seam lap type and plate seam strip type curtain wall. This kind of open decorative layer curtain wall outside the enclosing wall forms a sunshade and ventilation air compartment, while the small amount of rain water entering the air compartment evaporates through the effect of natural ventilation, effectively protecting the wall system behind.
(2) closed curtain wall: sealing measures are taken between the joints of curtain wall plates, and the building curtain wall has air-tight and water-tight performance. Closed curtain wall includes: glue injection closed and rubber strip closed. This is also a decorative artificial panel curtain wall with a solid wall behind it.

FT curtain wall (1)

Building envelope curtain wall is a building curtain wall that separates indoor and outdoor space and directly contacts indoor and outdoor air with peripheral protection and decoration functions, that is, the all-functional curtain wall commonly referred to in the industry. Artificial plate curtain wall the enclosure curtain wall without solid wall behind includes the following two types of closed curtain wall:
(1) Single panel system enclosure system: a closed curtain wall with only one layer of plate structure. (Similar to enclosure type glass curtain wall)
The integration of external wall and internal wall panel -- body enclosure system: the integration of external wall panel and internal wall panel and its supporting framework and thermal insulation and fire prevention materials, is the development direction of high-rise and super high-rise building curtain wall prefabrication, assembly industrialization.

As for the open artificial curtain wall panel with ventilation back, relevant tests show that the open curtain wall bears lower wind load compared with the closed building curtain wall. However, due to the influence of various factors such as facade shape, plate seam structure, slit width size, slit length per unit area, and less experimental data, it is not possible to give a unified reduction factor at present. In curtain wall design, reduction coefficient can be determined by wind tunnel model test according to the actual engineering situation.product-curtian-walls
