前建筑外墙砂浆类保温产品市场比较混乱、质量参差不齐,有些产品保温性能差,有的工程进场材料不认真查验技术文件,不作复验,盲目使用;有的工程保温层施工厚度不足、存在偷工减料的现象;有的工程施工不规范,随意操作,没有严格按标准要求进行分层、分遍施工等,造成保温层开裂和达不到保温效果等诸多质量问题。为确保建筑节能工程质量,加保温砂浆保温材料在建筑外墙保温系统应用的质量管理,现提出如下意见,请认真参考执行。

Before the building exterior wall thermal insulation mortar products in a cluttered market, quality is uneven, some product heat preservation performance is poor, some engineering approach materials without carefully checking technical documents, do not make the reinspection, blindly use; Some insufficient thickness of insulation construction, there are corners phenomenon; Some engineering construction is not standard, free operation, not strictly according to standard requirement, through construction and layered, cause insulation cracking and reach the heat preservation effect, and many other quality problems. In order to ensure the construction energy conservation project quality, strengthening pulp class insulation of exterior wall thermal insulation system application in construction quality management, we put forward the following opinions, please reference carefully executed.

  

一、在省《居住建筑节能工程施工技术规程》(DBJ13-82-2006)和《居住建筑节能工程施工质量验收规程》(DBJ13-83-2006)的主导系统是墙体自保温体系和板状类的外墙外保温系统。各施工段应谨慎使用浆料类外墙外保温系统。

One, in the province of the residential building energy conservation engineering construction technical regulation (DBJ13-82-82) and the residential building energy conservation engineering construction quality acceptance procedures (DBJ13-83-83) is leading system since the wall thermal insulation system and external thermal insulation system of slab. The construction period should be careful to use slurry exterior insulation system.

  

二、对于胶粉聚苯颗粒保温砂浆外墙外保温系统,各单位在使用时,其产品性能、设计、施工和验收等技术条件应严格按行业标准《胶粉聚苯颗粒外墙外保温系统》(JG158-2004)和《外墙外保温工程技术规程》(JGJ144-2004)要求执行,认真查验由生产厂商提供的产品合格证、出厂检验报告、有效期内耐侯性检验报告,采用面砖作饰面层的项目生产厂商还应提供抗震试验报告,并按有关标准规定进行复验,保温浆料施工前应制作同条件试件,检测其导热系数、干密度、抗压强度、软化系数和凝结时间,否则不得在工程中使用。

On powder polystyrene particles insulation pulp, exterior insulation system, each unit is in use, the product performance, design, construction and acceptance technology conditions should be strictly in accordance with industry standards, the powder polystyrene particles exterior insulation system (JG158-2004) and "regulations of technology of exterior insulation engineering" (JGJ144-2004) requirements, carefully check the product certificate provided by the manufacturer, the factory inspection report, the period of validity of the weathering resistance test report, the brick act the role of road surface of the project manufacturer shall also provide the seismic test report, according to provisions of relevant standards and conduct re-inspection, insulation slurry before construction should make specimens with conditions, testing the coefficient of thermal conductivity, dry density, compressive strength and softening coefficient and the setting time, otherwise it shall not be used in engineering.

  

对于国家和地方暂无应用技术标准的其它类不在本通知禁止使用范围的外墙外保温浆料类砂浆,原则上不宜在工程中使用;确实需要的,应由建设单位提出,经设区市建设局组织专家论证通过,并形成相应的专项设计、施工和验收技术文件后,方可试点使用。

No application for state and local technical standard of other classes to be outside the scope of this circular banning the use of exterior insulation class mortar paste, in principle should not be used in the engineering; Really need, should be put forward by the construction unit, approved by the districts and the city construction bureau organization expert argumentation, and form a corresponding special design, construction and acceptance technology documents, pilot can use.

  

禁止水泥聚苯颗粒砂浆(聚苯颗粒与水泥混合成型,禁止原因:国家和地方没有标准、产品保温性能和粘结性能差)和以膨胀珍珠岩、海泡石、有机硅复合的墙体保温浆料(禁止原因:国家和地方没有标准、热工性能差、手工湿作业、不易控制质量)作为建筑外墙保温隔热材料使用。

Ban cement polystyrene particles of mortar (polystyrene particles mixed with cement forming, banned reason: national and local standards, products insulation performance and poor bonding performance) and with expanded perlite, sepiolite, organic silicon compound wall insulation paste (banned reason: national and local standards, poor thermal performance, wet manual operation, not easy to control the quality) used as building exterior wall thermal insulation materials.

  

三、采用浆料类产品作为外墙外保温的工程项目,设计时应严格控制在该系统的适用范围之内,保温层设计厚度不宜超过30㎜,导热系数不应大于0.06w/m.k,干密度应控制在180-250kg/m3范围内。当保温层设计厚度超过30㎜时,不得采用浆料类外墙外保温系统,应改用其他保温体系。

Three, the pulp products as external wall thermal insulation engineering project, the design should be strictly controlled within the scope of the system, the thermal insulation layer thickness design should not be more than 30 ㎜, coefficient of thermal conductivity should be not more than 0.06 w/m.k, dry density should be controlled in the range of 180-250 kg/m3. When the thickness of insulation layer design more than 30 ㎜ shall not adopt any pulp exterior insulation system, should be to switch to other heat preservation system.

四、保温浆料层只能作为保温浆料系统中的保温层使用,不得作为墙体基层的砂浆找平层和保温系统的抗裂层使用,保温层厚度要均匀,不允许负偏差,防止产生热桥,降低节能效果。

Four, insulation slurry layer can only be used as insulation slurry system of thermal insulation layer, shall not be used as the wall at the grass-roots level of mortar leveling layer and crack resistance of thermal insulation system, insulation layer thickness uniform, do not allow the negative deviation, prevent to produce hot bridge, reduce the energy saving effect.

  

五、保温浆料外墙外保温应严格按国家或地方标准和下列有关要求施工:

Five, the heat preservation exterior insulation paste should strictly according to the relevant requirements of the national or local standards and the following construction:

1、施工前应制定专项的施工技术方案并经监理单位(建设单位)审批后方可施工。施工现场应对从事建筑节能工程施工作业的专业人员进行技术交底和必要的实际操作培训,以保证节能效果。对于从未做过的施工工艺,或者其他单位虽已做过但是本施工单位尚未做过的施工工艺,应进行“预演”并进行评价,需要时应调整配合比等参数再次演练,直至达到要求。提倡专业化施工。

1, before construction should make special construction technology scheme and the supervision unit (the construction unit) approval rear can construction. The construction site to professionals engaged in building energy conservation engineering construction operations necessary for technical clarificaiton and actual operation training, in order to keep the energy saving effect.

3、浆料保温层应分层施工,浆料保温层与基层和面层之间以及层和层之间的粘结必须牢固,不应脱层、空鼓和开裂。胶粉EPS颗粒保温浆料施工时,每遍厚度不宜超过15mm、间隔时间应大于24h,第一遍抹灰应压实、最后一遍用大杆搓平。

3, paste insulation layer should be layered construction, insulation layer between base and surface sizing agent and the bonding between layer and layer must be strong, should not to take off the floor, empty drum and cracking. In construction of powder EPS particles insulation slurry, each time shoulds not be more than 15 mm thickness, time interval should be more than 24 h, the first time rendering should be compacted, finally the rub with big stick flat again.

  

4、同层保温浆料宜连续施工。保温浆料厚度应均匀,接茬应平顺密实;现场配制的材料如保温浆料、聚合物砂浆等,应按设计要求、施工方案或试验室给出的配合比配制。在施工时应在抹面层施工前控制封闭在保温浆料层内的实际含水率,以确保保温效果。

4, provided appropriate continuous construction of insulation coating. Insulation paste thickness should be uniform, summer-planting should smooth dense; Site preparation materials such as thermal insulation paste, polymer mortar, should according to the design requirements, construction plan or laboratory of mixture preparation is given. Before construction should be in the plaster layer control closed the actual moisture content in insulation slurry layer, in order to ensure the heat preservation effect.

  

5、浆料外墙保温系统除面层外应逐层进行隐蔽验收,随做随验,并应有详细的文字和图片反映,主要包括:1)基层、保温层、抹面层、饰面层的构造做法及其表面处理;2)保温层厚度、垂直度和尺寸偏差;3)建筑的抗震缝、伸缩缝、沉降缝的保温构造节点做法;4)墙体热桥部位如:挑出附墙柱、女儿墙、外墙装饰线及缺陷部位如穿墙套管、孔洞脚手眼的保温、隔断修补措施;5)增强网的铺设、搭接方法。

5, exterior wall thermal insulation system in addition to the surface sizing agent shall be carried out step by step a covert acceptance, as you do, check, and should have the words and pictures reflect in detail, mainly including: 1) the basic level, insulation, plaster layer, act the role of the structure of the surface approach and its surface treatment; 2) insulation layer thickness, verticality and dimensional deviation; 3) construction of aseismatic joint, expansion joints and settlement joints insulation structure nodes; 4) wall thermal bridge parts such as: pick the attached column, parapet, exterior wall decorative thread and defective parts such as wear casing wall, hole feet hand-eye repair measures of heat preservation, partition; 5) to strengthen network laying, overlapping method.

  

六、验收管理:

Six, acceptance management:

  

1、现场检查保温层厚度应符合设计要求,不得有负偏差。

Should comply with the design requirements of insulation layer thickness of 1, on-site inspection, can not have negative deviation.

  

2、各节能分项工程的隐蔽工程验收记录、施工记录及施工质量验收记录等应齐全。
