防止外墙保温层脱落的方法,你了解吗?
来源:/ 日期:2018-08-14 发布人:admin

分析建筑外墙保温脱落问题出现的种种原因,主要从材料、设计和施工三个方面控制,以降低保温系统脱落质量隐患。
This paper analyzes the causes of insulation shedding of building exterior wall, mainly from three aspects of material, design and construction control, in order to reduce the hidden danger of insulation system shedding quality.
1、做好保温系统材料选取和控制
1, do the selection and control of insulation materials.
控制建筑外墙保温系统中聚合物砂浆、保温板材及锚栓等材料的质量。胶粘剂应科学配比,保证聚合物含量及配套助剂等;保温板质量应合格,对于岩棉、XPS板、PU板等应采取相应措施加强,比如岩棉板应加强锚栓固定,XPS板应增刷界面剂改善粘结性等等。锚栓在选择时应根据基层墙体类型选择锚栓类型以及锚栓深度,确保达到锚固力要求,防止锚栓锚固力失效,没有达到锚固作用。
Control the quality of polymer mortar, insulation board and anchor bolt in building external wall insulation system. Adhesives should be scientifically proportioned to ensure polymer content and supporting additives; insulation board quality should be qualified, for rock wool, XPS board, PU board should be strengthened, such as rock wool board should be strengthened anchor bolt fixation, XPS board should be brushed interface agent to improve adhesion and so on. When choosing anchor bolts, the type and depth of anchor bolts should be selected according to the type of base wall, so as to ensure that the anchor force requirements are met and prevent the anchor force from failing to achieve the anchorage effect.
2、墙体保温系统设计合理
2, the design of wall insulation system is reasonable.
墙体保温工程是一个系统工程,设计时需考虑各构造层的匹配性,对于自身强度较低或粘结性差的材料需设计锚栓加固、提高保温板粘结率等;外饰面选取时应与保温系统相匹配,宜设计为透气性好的涂装系统,对设计面砖的应采用柔性面砖,并合理设计分隔缝。
The wall insulation project is a systematic project, the matching of each structural layer should be considered in the design, the anchor bolt should be designed to reinforce the materials with low strength or poor cohesion, and the bonding rate of the insulation board should be improved; the external decoration should be matched with the insulation system, and the coating system with good permeability should be designed to design the face brick. Flexible tiles should be used and the seams should be designed rationally.

3、加强施工控制
3. Strengthen construction control.
施工作为建筑墙体保温工程质量控制的薄弱环节,施工前,需做好基层墙体检查验收,确保基层的拉伸粘结强度满足规范要求,墙面平整度在可控范围内,且无空鼓、粉化、油污等影响粘贴的现象;保温施工时需要加强施工工艺控制,保证粘结砂浆的涂布率,避免保温板虚贴,锚栓虚打,干挂网等不规范做法;保温系统施工前后,应注意天气变化和成品保护,避免砂浆固化前,雨水冲刷或阳光曝晒。
Construction is a weak link in the quality control of building wall insulation project. Before construction, it is necessary to do a good job of checking and acceptance of the base wall, to ensure that the tensile bond strength of the base meets the requirements of the code, the smoothness of the wall is within the controllable range, and there is no such phenomena as hollowing, powdering, oil pollution that affect the sticking. Process control, ensure the coating rate of bonded mortar, avoid the improper practices such as falsely pasting insulation board, falsely beating anchor bolts, dry hanging net; insulation system before and after construction, should pay attention to weather changes and product protection, to avoid the mortar before solidification, rain wash or sunlight exposure.
以上就是关于外墙保温层脱落的介绍,你有任何的疑问或问题,都可以前来公司咨询,感谢你对我们公司的关注,我们期待你的到来!
Above is about the introduction of exterior wall insulation layer fall off, you have any questions or questions, you can come to the company to consult, thank you for our company's attention, we look forward to your arrival!
