今天,我们英语课非常非常吵,所以被老师扣了我们班的分。
我们上了两节英语课,每节课都被英语老师扣了两分,总共两节英语课被英语老师扣了四分,所以班主任罚我们写400字的保证书。
我们刚上课老师教我们读英语单词时,我们不跟老师来读英语单词,所以被老师骂或扣分,但后来我们有读英语。读很大声了,但是不知道为什么扣我们班的分。
一、概述:
因我区气候寒冷,属于采暖居住地区,居住建筑都应该采取节能措施。为了改变我区落后的节能步伐,尽快赶上全国节能先进城市,我区根据,<<国家建筑节能强制性标准2008.3.1日实施 >>积极鼓励发展下列建筑节能技术和产品:
(一)新型节能墙体和屋面的保温、隔热技术与材料;
(二)节能门窗的保温隔热和密闭技术;
因此就《外墙外保温工程技术规程》JGJ144-2004在我区实施,新的居住节能设计标准要求节能65%,也就是在保证相同的室内环境参数条件下,与未采用节能措施相比,全年采暖、通风、空调和照明的总能耗减小65%。这样就要求居住建筑必须采用外墙外保温设计系统方能达到这一新的节能标准。
我们现在的居住建筑,设计上基本都采用了外墙外保温系统。目前外墙外保温系统主要有:膨胀聚苯板(EPS)薄抹灰外墙外保温系统,胶粉EPS颗粒保温砂浆外墙外保温系统,膨胀聚苯板(EPS)现浇混凝土外墙外保温系统,EPS钢丝网架板现浇混凝土外墙外保温系统,机械固定EPS板钢丝网架板外墙外保温系统等五种。这五中外墙外保温系统中,我们现在在施工中接触较多的有:EPS钢丝网架板现浇混凝土外墙外保温系统(即有网现浇系统),膨胀聚苯板(EPS)薄抹灰外墙外保温系统,胶粉EPS颗粒保温砂浆外墙外保温系统。前一种在我们施工的工程中多用于现浇混凝土框架剪力墙结构的外墙外保温系统,后两种多用在多层多孔砖砌体结构。
二、外墙外保温节能技术的应用和质量保证
现就外墙外保温节能技术的应用和质量保证进行案例阐述:
工程概况:新疆乌市公交公司一厂住宅楼:建筑面积3800.8平方米,总高度:21.8米。全面采用膨胀聚苯板(EPS)薄抹灰外墙外保温系统。
(一)首先:要了解其外墙外保温的系统应用,应先清楚本案例住宅楼外墙外保温体系的组成和结构,依次为:结构墙体、粘结层、保温层、抹面胶浆、玻璃纤维网格布、饰面层。其中粘结层一般由粘结胶浆构成,视需要可附加铆钉,如基面不符合粘贴要求,还需采用机械法固定。保温层一般是阻燃型聚苯乙烯泡沫板(EPS),也可以是挤塑板(XPS)等,厚度按各地节能要求选择。防护层是由抹面胶浆和玻璃纤维网格布组成。饰面层可选用防开裂性、拒水性、透气性和耐候性等较好的外墙涂料等。目前,国内推广应用外保温体系常见的问题是表面开裂、空鼓和渗水。开裂和渗水的外墙外保温比不做外墙外保温的影响还坏,而且很难修复。防护层是决定整个外保温体系性能的关键,防护层做好了,外墙外保温的抗裂性就有了基本保证。
在对本案例住宅楼外墙外保温体系的施工中还应该着重掌握《外墙外保温工程技术规程》JGJ144-2004中的几个强制性条文的要求。即该规范第4.0.2、4.0.5、4.0.8、4.0.10条、5.0.11、6.2.7、6.3.2、6.4.3、6.5.6、6.5.9有关规定。应该注意设计图纸是否对外保温工程的密封及防水措施进行设计,尤其是对一些重要部位、节点的构造详图。除了现浇式外墙外保温系统外,还应注意施工时基层施工质量是否满足下到工序的施工。基层应坚实、平整,洁净无油污,凸起、空鼓、疏松的部位应剔除或找平,并在保温层施工前对基层进行处理。EPS板表面不应长期裸露,应在安装后及时抹灰。薄抹面层施工时,玻纤网不得直接铺在保温层表面,应该满铺薄抹面层中,不得干搭接,不得外露。EPS板薄抹灰系统建筑物在20m以上的承受负风压作用的部位应使用锚栓辅助固定。在这一系统中的EPS板宽度不宜大于1200mm,高度不宜大于600mm。基层也应经过处理,并且不得有脱层、空鼓、裂缝,面层不得有粉化、起皮、爆灰。胶粘剂应均匀地涂抹在EPS板背面,并且涂抹面积不得小于板面积的40%。还应该注意对檐口等处的包边处理,对装饰缝、门窗四角、阴阳角处的局部加强施工的质量监督。胶粉EPS保温颗粒外墙外保温施工,重点检查施工玻纤网是否满铺在薄抹面层中,保温层施工厚度是否达到设计要求,是否分层对保温浆料进行抹灰。并且分层抹灰每层之间时间间隔宜在24小时以上,每层厚度不宜超过20mm。否则就会出现裂纹等一系列的质量问题。
(二)其次:外墙外保温是目前实现建筑节能最行之有效的节能方式,作为其外墙饰面材料的应用,建筑涂料是首选。根据国家JG149—2003《膨胀聚苯板薄抹灰外墙外保温系统》的规定,涂料必须与薄抹灰外保温系统具有很好的相容性,性能指标应符合外墙建筑涂料的相关标准。除了要达到有效的节能和理想的装饰效果外,还应该关注其他一些问题。
溶剂型涂料不能用于外墙外保温体系。因为外墙外保温体系一般采用聚苯乙烯(EPS、XPS)或聚氨酯(PU)等为保温层,根据相似相溶原则,溶剂材料,如苯和甲苯等能溶解聚苯乙烯,醋酸丁酯和二甲苯等能溶解聚氨酯,聚苯乙烯保温层被溶蚀而使外墙外保温层表面凹凸不平。
1、涂料的拒水透气性
国家标准JG149-2003《膨胀聚苯板薄抹灰外墙外保温系统》中规定,外保温系统的5mm厚防护层,浸水24h,吸水量要≤500g/㎡;外保温系统防护层和饰面涂层一起水蒸气湿流密度要≥0.85g/(㎡.h)。在JGJ144—2004《外墙外保温工程技术规程》对此规定有些不同。以JG149-2003中的规定来看,对于外墙面,就吸水性来说,一般外层要求比内层低,也就是说外饰涂层要低于防护层,即涂层吸水量要少于500g/㎡,这样才能使比较少的水进入墙体;就水蒸气湿流密度来说,一般外层要求比内层高,也就是说外饰涂层要高于防护层,即涂层水蒸气湿流密度要远远大于0.85g/(㎡.h),这样水蒸气才能畅通无阻地排出。
