In architecture, a window refers to an opening built on a wall or roof to let light or air into a room. As early as the Sui Dynasty in China, there were windows that could be opened and closed automatically in the Guanwen Temple in the Wei Zi Palace. ?
In fact, the original meaning of window and door refers to window and door respectively, while in modern Chinese, window only refers to window. "Window" was originally called "chimney" ("chimney" is a common word), that is, a hole is left in the wall, and the window lattice in the frame can transmit light or smoke, and the prefix "hole" is added to form pictophonetic characters. Shuowen said: "Those who go up the wall are called it, and those who go up to the temple are called it". Windows, or through holes. "The window frame is responsible for supporting the main structure of the window. The material can be wood, metal, ceramic or plastic, and the transparent part is attached to the window frame. The material can be paper, cloth, silk or glass.
During the Sui Dynasty in China, there were windows that could be opened and closed automatically in the Guan Wen Hall of Wei Zicheng in Luoyang Palace.
"There are 14 study rooms in front of Guanwen Temple, with window mattresses and kitchen curtains, which are extremely salty and beautiful. Every three rooms have square doors and brocade curtains, and there are two flying fairies on the ground. On the outdoor ground, the emperor is lucky in his study. Imperial secretary flew down with a censer, drew the curtain and went up. As soon as the emperor came out, he hung up and closed. " (History as a Mirror, Volume 182)
-There are fourteen luxurious libraries in front of Guanwen Temple, with brocade curtains hanging at the door, two flying immortals above the door, and organs outside. When Yang entered the library, the imperial secretary stepped forward and moved the organ. I saw the flying fairy falling, the brocade curtain rising, and the library windows and bookcase doors automatically opened. When Yang Guang leaves the library, everything will be restored automatically.
Modern windows consist of window frames, glass and movable parts (hinges, handles, pulleys, etc.). ).
It consists of three parts. The window frame is responsible for supporting the main structure of the window, and the material can be wood, metal, ceramic or plastic. The transparent part is attached to the window frame, and the material can be paper, cloth, silk or glass. Movable parts are mainly made of metal materials, and may be wrapped by heat insulation materials such as plastic where people touch them.
With the development of building technology and the improvement of human living standards, the structure of windows has become more and more complicated to meet higher thermal requirements. High-grade buildings will use double or even three layers of vacuum Low-E glass and double-layer rubber sealing strips to ensure their best thermal insulation performance. The horizontal skylight can be made into a frameless unit, also called a lighting cover. Glass curtain wall can be regarded as a special kind of window, that is, the whole building exterior wall has become a light-transmitting window.
