【摘要】：在我国,民用建筑绿色、节能的发展体现了建筑业落实科学发展观,实现可持续性发展的战略。目前,国家对建筑节能问题相当重视,出台了一系列政策,也投入了相当大的人力、财力和物力资源,建筑节能得到了快速发展。论文在分析目前市场中常用的八种外墙外保温体系的基础上,结合当地外墙外保温市场存在的一些问题,提出了相应的管理体制及其针对性的对策。民用建筑外墙外保温工程施工质量是建筑节能工作急需解决的难题。由于市场上外保温材料、品种、性能及质量的参差不齐,对外墙外保温的系统性能及综合质量产生了一定影响。以典型保温技术为例,分析了对系统性能及其组成材料性能对保温工程质量的影响,对施工过程中易出现的质量问题进行了研究,提出了如下措施：首先保温材料要选择合格的工程材料,并保证各种材料的匹配及相容性,材料进场时要核查证明文件、产品合格证、产品性能检测报告,是否符合设计要求,要核实检验机构的合法性以及检验报告的时效性；其次要做好施工前的准备工作,包括基层墙体的处理,编制专项施工方案等；三是施工过程中网格布应压于抹面层内,表面防裂砂浆分两次施工的总厚度控制在3mm-6mm,应完全覆盖网格布；四是尽量采用条粘法进行粘结,避免发生墙体空鼓,防止聚苯板四周翘曲变形,阻止发生由于封边不严时产生保温墙体渗水、透风甚至脱落的现象。从施工组织与质量关系、施工质量的验收与监督管理及外保温工程成品质量的防护三个方面来防治和解决外保温工程在施工中出现的质量问题。在外墙外保温施工过程中应严格执行各项技术管理规定,各级岗位责任制,严格按照审查合格的施工图、技术规范、规程和工艺标准进行施工,并贯彻“三级”技术交底制,强化细部节点的监督与验收,落实好成品质量防护措施。以滨河新城小区外墙外保温工程为案例,具体分析了外墙外保温施工过程中的质量控制节点,使其起到应有的效果,建筑达到节能标准要求。论文在对工程实际的施工组织、存在问题以及工程案例分析的基础上,提出了切实可行的、适合当地外墙外保温市场发展的管理方法及其针对性措施。总之,要不断提高建筑外墙外保温施工的质量管理水平,使建筑能够达到预期节能的效果,为节能减排发挥作用。
[Abstract]:In our country, the development of green and energy saving of civil buildings embodies the strategy of implementing the scientific development view and realizing the sustainable development of the construction industry. At present, the state attaches great importance to the problem of building energy conservation, and has issued a series of policies. Also invested in considerable human, financial and material resources, building energy conservation has been rapid development. Based on the analysis of eight kinds of exterior wall insulation systems which are commonly used in the market at present, this paper combines some problems of the local external wall external insulation market. This paper puts forward the corresponding management system and corresponding countermeasures. The construction quality of the exterior wall thermal insulation project of civil buildings is a difficult problem to be solved urgently in building energy conservation work. Due to the variety of external insulation materials in the market. The uneven performance and quality have a certain impact on the system performance and comprehensive quality of external insulation. Take typical insulation technology as an example. The influence of system performance and component material performance on the quality of thermal insulation engineering is analyzed, and the quality problems which are easy to appear in the construction process are studied. The following measures are put forward: first of all, the insulation materials should select qualified engineering materials, and ensure the matching and compatibility of various materials. When the materials enter the field, they should check the proof documents, product certificates, and product performance testing reports. Whether meet the design requirements, to verify the legitimacy of the inspection agency and the timeliness of the inspection report; Secondly, the preparatory work before construction should be done well, including the treatment of the base course wall, the compilation of the special construction plan and so on; Third, the mesh should be pressed in the surface layer in the construction process, the total thickness of the surface anti-cracking mortar in two times construction should be controlled in 3mm-6mm, and the mesh should be completely covered. The fourth is to use the method of adhesive to avoid wall cavity, prevent the warpage around the polystyrene board deformation, prevent the occurrence of insulation wall water seepage due to the edge is not strict. The phenomenon of ventilation and even shedding. From the relationship between construction organization and quality. The acceptance and supervision management of construction quality and the protection of finished product quality of external insulation engineering are three aspects to prevent and solve the quality problems in the construction of external insulation engineering. Every item should be strictly carried out in the construction process of exterior wall external insulation. Technical management regulations. Post responsibility system at all levels, strictly in accordance with the examination of qualified construction drawings, technical specifications, procedures and technical standards to carry out construction, and implement the "three-level" system of technical bottom, strengthen the supervision and acceptance of detail nodes. Take the exterior wall thermal insulation project of Binhe Xincheng district as a case, the quality control node in the construction process of exterior wall thermal insulation is analyzed in detail to make it play its due effect. The building meets the requirements of energy conservation standards. On the basis of the actual construction organization, existing problems and case analysis of the project, the paper puts forward a feasible and suitable management method and targeted measures for the development of the local external wall external insulation market. It is necessary to continuously improve the quality management level of the external insulation construction of the external wall so that the building can achieve the expected energy saving effect and play an important role in energy saving and emission reduction.
