某大楼玻璃幕墙工程由A公司承担施工。隐框玻璃幕墙采用的中空玻璃由A公司委托玻璃厂加工,采用两道密封,第一道为丁基热熔密封胶密封,第二道采用聚硫密封胶密封,胶缝尺寸由玻璃加工厂按普通门窗中空玻璃的胶缝尺寸确定。隐框幕墙的玻璃板块由A公司下属加工厂制作,玻璃与铝合金框采用双组分硅酮结构密封胶黏结。半隐框玻璃幕墙采用单片镀膜玻璃,其玻璃面板上墙安装就位后,直接在现场注胶,玻璃的镀膜面朝向室外一侧。

隐框玻璃幕墙的玻璃板块制作时间是2004年10月10日~10月15日,安装时间是同年10月30日~11月lO日。板块制作中,按规定作了剥离试验,均合格。

在幕墙构件制作安装前,A公司对隐框和半隐框玻璃幕墙分别制作了试样,委托有资质的检验单位检测三项主要物理性能。根据设计图纸,隐框幕墙立柱跨度有3200mm、3400mm和3600mm三种规格;幕墙除分格高度根据立柱跨度不同按比例有所增减外,其所用主材型号、品种、胶缝尺寸以及作用于幕墙单位面积上的力均相同。A公司的试样是按立柱跨度3400mm制作的。

For over one hundred and fifty years, Americans of all social classes have worn blue jeans.  61 Whether they are worn for work or for fashion today.Strauss' invention continues to be popular not only among Americans but also among people around the world.

Levi Strauss was born in Germany in 1829.  62 He grew up in Kentucky before moving to New York in 1847.Before becoming an American citizen and moving to the West in 1853, Strauss worked in his brother's dry goods business.This gave him a chance to produce his famous invention.After the gold rush of 1949, Strauss decided to move to the West to seek his fortunes.

Strauss did not want to be a person who searched an area for minerals.Instead, he knew he could make a good living by selling supplies to the miners.At first, he planned to sell sewing supplies and cloth.63 When he heard miners complaining that their clothes were easily broken or they usually tore their pockets during mining, he decided to use a special fabric to make pants for the miners.These pants proved so popular that he quickly ran out of materials to make more.

In 1873, Strauss received a letter from a Jewish tailor named Jacob Davis who had invented a process of connecting pockets with copper rivets(铆钉).This made the pants last a long time.Because Davis did not have the money to patent his idea, he offered to share it with Strauss if Strauss would agree to pay for the patent.  64
