能源题目已经成为制约我国经济和社会发展的紧张因素,本着坚持开发与节约并举、节约优先,大力节能降耗,进步能源行使服从的方针,必要在各行业推进节能工作。我国正处在建筑业大发展的时期,建筑能耗的节能已经成为最大的节能项目,推进建筑节能广西快3,就必要大力推动新建住宅和公共建筑严酷执行节能50%的设计标准,但从目前建筑物的墙体节能等施工情况来看,工程的质量题目紧张,围护结构外墙的质量题目尤其凸起,下面笔者就目前墙体节能工程中的保温装饰一体板设备浆料施工的质量题目及产生的缘故原由和预防措施谈一些看法。


1.墙体保温装饰一体板设备节能工程中保温装饰一体板设备浆料施工存在的题目


在我们所处的夏热冬冷地区,保温装饰一体板设备节能工程周全开展施工时间较晚,施工工艺不是很成熟,墙体设计多为胶粉聚苯颗粒保温装饰一体板设备浆料或玻化微珠保温装饰一体板设备浆料,存在材料以次冲好,施工现场墙体材料乱堆乱放,不能严酷按设计图纸施工,浆料厚度超过30mm时不能分层进行,以至在施工后墙体出现外墙龟裂、外墙外保温装饰一体板设备材料脱落、外墙与墙体连接处保温装饰一体板设备材料不良、冷热桥部门施工不到位等情况。

3.2墙体节能施工前应按照设计和施工方案的要求对下层进行处理。保温装饰一体板设备层所附着的墙面,通常是主体结构的外观(混凝土或砌体外观)。主体结构施工时,每每并未考虑保温装饰一体板设备材料粘结的要求,其平整度、光洁度以及施工过程中产生的粉尘等到附着物和污渍可能会给节能材料的粘结带来困难。为了保证墙体节能材料能牢固地粘结在主体结构的外观商用电锅炉,要求在浆料施工前,用钢丝刷在消灭下层墙面浮灰、油渍等,再用软刷扫干净。对墙面凸、凹部分应进行剔平或修补处理,用钢丝刷清理墙面孔洞,并用1:3水泥砂浆或保温装饰一体板设备浆料堵塞洞口。


3.3保温装饰一体板设备层隔热材料的厚度必须吻合设计要求,保温装饰一体板设备浆料应分层施工。首先在墙体上涂刷界面砂浆,用喷枪或滚刷将界面砂浆均匀涂刷于墙面上,不得漏刷。其次弹厚度控制线,打点冲筋,行使500mm水平控制线向上每间隔1m返一道水平线,然后布点,做保温装饰一体板设备材料做灰饼,冲筋。其厚度应以墙面最高处抹灰厚度不小于设计厚度为准。抹聚苯颗粒保温装饰一体板设备砂浆,每遍施工间隔应在24h以上,每遍厚度不宜大于20mm成都人事考试网,最后一遍施工厚度宜控制在10mm左右,达到灰饼或冲筋厚度,墙面平整度和垂直度应达到规定要求。每抹完一个墙面,用大杠找直,抹完 2h后,用抹子压实赶平。保温装饰一体板设备砂浆应采用机械搅拌,机械搅拌时间不宜少于3min,且不宜大于6min。搅拌好的砂浆应在2h内用完。
