Description

隔热保温型双层玻璃幕墙
技术领域
本实用新型涉及夹层玻璃领域,具体为一种隔热保温型双层玻璃幕墙。
背景技术
建筑幕墙在我国已历经将近二十年的发展,从节约能源的角度出发,现有的玻璃幕墙开始采用双层玻璃制造,利用空气的绝热性能,双层玻璃的隔热性要强于单层玻璃,如某型填充氩气的中空玻璃,传热系数K值为1.6w/m2·k~1.8w/m2·k。但随着能源供应紧张的趋势以及低碳排放要求的增加,双层玻璃的隔热性能仍不能使人满意,还需进一步提高。
实用新型内容
为了克服现有技术的缺陷,提供一种结构简单、成本低廉、隔热效果好的夹层玻璃,本实用新型公开了一种隔热保温型双层玻璃幕墙。
本实用新型通过如下技术方案达到发明目的:
一种隔热保温型双层玻璃幕墙,由夹层单元组成,夹层单元至少有一块,夹层单元包括内层玻璃和外层玻璃,内层玻璃和外层玻璃平行设置,内层玻璃和外层玻璃之间抽成真空,其特征是:还包括气凝胶层,气凝胶层设于内层玻璃和外层玻璃之间,且气凝胶层的两个侧面分别贴合内层玻璃和外层玻璃,内层玻璃的厚度和外层玻璃的厚度相等,气凝胶层的厚度是内层玻璃厚度的80%~120%。
所述的隔热保温型双层玻璃幕墙,其特征是:当夹层单元的数量大于一块时,夹层单元的排列采用横向纵向均对齐、横向对齐纵向交错和横向交错纵向对齐中的任意一种,相邻夹层单元的拼接处予以密封。
所述的隔热保温型双层玻璃幕墙,其特征是:内层玻璃和外层玻璃之间的绝对真空度不大于50kPa。
本实用新型采用玻璃夹层内填入气凝胶再将间隙抽成真空的方法,切断了气体传导和对流的热传递途径,气凝胶层选用二氧化硅气凝胶等薄层气凝胶材料,具有优异的隔热保温性能,K值约为0.012w/m2·k~0.018w/m2·k,远小于普通夹层玻璃的K值,冬季能阻止室内暖气的热辐射向外泄漏;夏季可防止外面的热辐射进入室内,从而达到节能的目的。本实用新型可广泛应用于房屋建筑、公共建筑、建筑用门窗玻璃、汽车用门窗玻璃和火车用门窗玻璃等领域。本适用新型的有益效果是:结构简单,成本低廉,隔热效果好,适用范围广。
附图说明
图1是本实用新型的结构示意图;
图2是本实用新型采用横向纵向均对齐方式排列的示意图;
图3是本实用新型采用横向对齐纵向交错方式排列的示意图;
图4是本实用新型采用横向交错纵向对齐方式排列的示意图。
具体实施方式
以下通过具体实施例进一步说明本实用新型。
实施例1
