1、 解决玻璃材料构件间结构不牢固问题玻璃幕墙是用铝合金或其他金属轧成骨架，以玻璃封闭的空腹型杆件作成的房屋围护墙。有单层和双层玻璃二种墙体；反光绝缘玻璃厚6 mm，墙面自重约40 kgm2；幕墙外层玻璃的里侧涂有彩色的金属镀膜等。Glass curtain wall is made of aluminum alloy or other metal rolling into a skeleton, with a closed hollow glass building enclosure wall type bar. There are two kinds of single and double
2、 glass wall; Reflective insulation glass thickness of 6 mm, metope weight of 40 kg/m2; In the side of the wall of the outer glass coated with colored metal coating, etc. 12优点1.2 advantages 玻璃幕墙的优点有：可吸收红外线；减少进入室内的太阳辐射；降低室内温度；轻巧美观；不易污染；节约能源；在光线的反射下，室内不受强光照射，视觉柔和等。Glass curtain wall has the advantages
3、of: can absorb infrared light; Cut into the interior of the sun radiation; Reduce indoor temperature; Light is beautiful; Not easy to pollution; To save energy; Under the reflection of light, indoor is not affected by glare, visual downy, etc. 另外，在 现代 化高层建筑的玻璃幕墙中，还采用了由镜面玻璃与普通玻璃组合，隔层充入干燥空气的中空玻璃。中空玻璃是
4、一种良好的隔热、隔音、防结霜、防潮、抗风压强度大、美观适用、并可降低建筑物自重的新型建筑材料，它是用两片(或三片)玻璃，使用高强度高气密性复合粘结剂，将玻璃片与内含干燥剂的铝合金框架粘结，制作成的高效能隔音隔热玻璃。据实验检测，在冬天，当室外温度为10时，室内单层玻璃窗前的温度为2，而中空玻璃窗前的温度是13；而在夏天，双层中空玻璃可以挡住90的太阳辐射热；虽然阳光依然可以透过玻璃幕墙，但晒在身上不会感到炎热。因此，使用中空玻璃幕墙的房间可以做到冬暖夏凉，极大地改善了生活环境。In addition, in modern high-rise buildings of glass curtain
5、 wall, also used by the mirror glass and common glass combination, interlayer filling the hollow glass of dry air. Hollow glass is a kind of good heat insulation, sound insulation, frost proof, moisture, wind pressure strength big, beautiful and applicable, and can reduce the building self-respect o
6、f new building materials, it is to use two pieces of glass (or three), the use of high strength and high air tightness composite binder, the glass with aluminum alloy frame containing desiccant adhesive, insulation made of highly efficient heat insulation glass. According to the experiment testing,
7、in the winter, when the outdoor temperature is 10 , the indoor temperature is 2 in front of the single-layer glass Windows, and the temperature of the hollow glass window is 13 ; In summer, the double-layer hollow glass can block 90% of solar heat; Although the sunlight can still through the glass c
8、urtain wall, but the sun in the body will not feel hot. Therefore, the use of hollow glass curtain wall of the room can be warm in winter and cool in summer, greatly improved the living environment. 2玻璃幕墙施工工艺及方法2 glass curtain wall construction technology and method 21玻璃幕墙施工的安全因素2.1 glass curtain wa
