[ä¸çŽ»ç’ƒç½‘] The curtain wall should have the following conditions:
1. The curtain wall must be composed of plates (glass, stone and metal, etc.), beams (aluminum profiles or sections, etc.), columns (aluminum profiles or sections, etc.) to form a separate structure independent of the main structure.
2. The structure that bears the load of the curtain wall itself should be outside the main structure.
3. The curtain wall should generally be suspended on the main structure (or supported on the main structure), and a certain displacement should be allowed relative to the main structure to meet the effects of wind loads and seismic loads.
4. The curtain wall is a peripheral protection member suspended or supported (such as a kind of all-glass curtain wall) on the main structure, which mainly plays a decorative role (such as stone curtain wall, metal curtain wall, etc.), and does not share Main structure load.
Windows should have the following conditions:
The so-called window is generally installed in the hole of the structure, and can not produce displacement with respect to the main structure, or the displacement is relatively small, and does not have the condition of the curtain wall, so the large-area glass is not equivalent to the curtain wall. The window can only be a window whether it is vertical or horizontal, but it is only necessary to carry out fireproof sealing treatment across the fire compartment.
An exterior wall with the following four characteristics can be called a curtain wall:
1. Suspended in front of the structural frame. (The eccentric pressure of the column can be reversed if it is not unstable.)
2. Loads that do not withstand the structural structure: non-load-bearing exterior walls that include horizontal and vertical loads.
3. The weight of the wall and the wind load received are transmitted to the structural frame of the building through the anchor point.
4. The joint design and connection process between the curtain wall components shall be such that the curtain wall is erected into any continuous side wall.
It is inlaid in the entrance of the building to install a structure that can transmit force. Whether it is made of curtain wall material or window material, it is called window.
