责任主体单位对建筑外墙保温工程不够重视

The responsible entity does not pay enough attention to the external wall insulation works

因为建筑在某种程度对建筑主体结构影响不很明显，又增加了工程造价，责任主体单位对建筑管理不够重视，总是随意变更施工图纸、施工方案，施工质量比较低下。一般表现在如下几个方面：

Because the impact of building energy conservation on the safety of the main structure of the building is not obvious to some extent, and the project cost is increased, the responsible entity unit does not pay enough attention to the management of building energy conservation, and always changes the construction drawings and construction schemes at will, resulting in low construction quality. It is generally shown in the following aspects:

一是随意变更保温体系，变更的施工图纸未经原图纸审查机构审查合格，导致工程的岩棉板保温效果难以满足原图纸设计。

First, the thermal insulation system was changed at random. The changed construction drawings were not reviewed and qualified by the original drawing review organization, resulting in the rock wool board thermal insulation effect of the project difficult to meet the original drawing design.

二是工程建设单位未经总承包单位同意的情况下，直接对保温工程肢解分包，人为割裂整个施工过程，通常把岩棉板保温工程分割为保温贴板工程及贴砖工程，人为分割保温和涂饰，二者互不关联，这就使得后期出现质量问题时职责不明、责任不清。

Second, without the consent of the general contractor, the engineering construction unit directly dismembers and subcontracts the thermal insulation project, and artificially splits the whole construction process. Generally, the rock wool board thermal insulation project is divided into thermal insulation board project and tiling project, and the artificial division of thermal insulation and painting are not related to each other, which makes the responsibility unclear and unclear when quality problems occur in the later stage.

三是监督人员、监理人员潜在认为建筑外墙保温工程对主体结构影响不大，监管措施不力、责任心不强。

Third, supervisors and supervisors believe that the external wall insulation works have little impact on the safety of the main structure, and the supervision measures are weak and the sense of responsibility is not strong.

设计和实际施工脱节，很难科学指导工程施工

The design is divorced from the actual construction, and it is difficult to scientifically guide the project construction

由于外墙保温技术推广应用的时间比较短，相关设计人员没有准确掌握设计规范和熟练运用外墙保温施工工艺，因而促使设计与施工脱节，很难有效地开展施工作业，主要表现在以下几个方面：

Due to the short time for the promotion and application of the external wall insulation technology, the relevant designers did not accurately master the energy-saving design specifications and skillfully use the external wall insulation construction process, which led to the disconnection between design and construction, and it was difficult to effectively carry out construction operations, mainly in the following aspects:

一是没有准确掌握外岩棉板适用范围，误把国外用在屋面与地面±0以下的墙面挤塑板(XPS)用在墙面上，加上没有对材料性能作出严格的控制，又没有开展耐候性试验进行验证，留下了极为严重的隐患。

First, the scope of application of external rock wool board was not accurately grasped, and the foreign wall extruded board (XPS) used below ± 0 on the roof and ground was mistakenly used on the wall. In addition, the material performance was not strictly controlled, and the weather resistance test was not carried out to verify, leaving a very serious potential safety hazard.

二是建筑外墙岩棉板在外保温饰面层上所采取的外墙保温体系和饰面材料不适应，导致外墙涂料面层出现开裂及空鼓现象，保温材料进水失去保温功能;一味寻求施工效果及耐久性而选择饰面砖作为饰面材料，外挂重量会在很大程度上高于外保温系统本身的重量与系数，经常导致外墙饰面砖脱落伤人，产生事故。

Second, the exterior wall insulation system adopted by the rock wool board of the building exterior wall on the exterior insulation and finishing layer is not suitable for the finishing materials, resulting in cracking and hollowing of the exterior wall coating surface layer, and the insulation material loses its insulation function due to water inflow; Blindly seeking the construction effect and durability and choosing the facing brick as the facing material, the external hanging weight will be much higher than the weight and safety factor of the external insulation system itself, which often leads to the falling off of the facing brick of the external wall and injury to people, resulting in safety accidents.

三是华美橡塑总代理认为施工人员对一些局部构造节点、冷热桥部位上的保温措施及防水设计重视不够，保温系统难以正常使用，进而促使墙体出现漏雨、返霜、结露及发霉现象。

Third, the general agent of Huamei Rubber & plastic believes that the construction personnel do not pay enough attention to the thermal insulation measures and waterproof design on some local structural nodes and cold and hot bridge parts, and the thermal insulation system is difficult to operate normally, thus causing the wall to leak rain, return frost, condensation and mildew.
