【摘要】：随着我国居民生活水平的提高,人们对生活起居的建筑热环境的要求也不断提高,伴随而来则是建筑能耗不断攀升,能源危机甚至成为影响我国经济持续健康发展的重要因素。为了有效的降低建筑能耗,推广绿色建筑理念,建筑外墙保温的发展受到越来越多的重视。我国常见的外墙保温材料有现场发泡保温材料、保温砂浆(保温粉)和保温板材,但随着人们环保意识的增强,各地建筑节能标准的不断提高,在75标准的要求下,聚苯板的上墙厚度120mm,岩棉板厚度更是需要达到140mm,大大增加了施工难度和施工工期,并且厚度的增加使得一直被人们诟病的外墙保温脱落的问题更加堪忧。原先的保温材料已经不能很好地满足我国特别是北方建筑节能的发展要求。在借鉴国外先进技术的基础上,经过国内多家机构的研发探索,原来用在冰箱,冷储箱的超薄真空绝热板被用在建筑外保温领域,较之60-100mm的EPS板,10-15mm厚的超薄真空绝热板保温性能更好,导热系数只有0.006w/m·K,保温效果是常规聚苯板的5倍、XPS的4倍、聚氨酯的3倍,能大大增加房屋的保温性能,防火等级达到A1级,安全不燃,并且能够增加房屋的使用面积。但由于其保温原理的特殊性,在施工和使用过程中要保证板材不能被损伤破坏真空,对施工质量有较高要求。真空绝热板作为一种新兴的外保温建筑材料,目前市场上还没有形成标准化的构造做法,不规范的建造方式很可能破坏真空绝热板材,造成墙体保温性能达不到应有的效果和材料的浪费等问题。本文以中亨新材的真空绝热保温产品为例,基于产品特点、施工经验和国家建筑相关规范和标准,对真空绝热板的系列产品进行了深入研究,总结和分析了真空绝热板的产品和对各个建筑节点的构造要求,并选取建筑实例进行实地分析研究。文章共分为五个章节:第一章为绪论部分,阐述国内外HVIP真空绝热板的研究和应用情况,对HVIP真空绝热板等相关概念进行介绍,说明本论文课题的研究内容和方法;第二章主要介绍了HVIP真空绝热板外墙外保温系统的产品系列,以各项参数为基础剖析各个产品的优劣及其适用性;第三章对不同HVIP真空绝热板外墙外保温体系的建筑节点构造进行了研究和设计。第四章通过对一应用了真空绝热外墙外保温体系的建筑案例进行介绍和分析,从建筑构造节点设计,以及其经济性、社会性等多个方面阐述真空绝热外墙外保温体系的优劣,为真空绝热板外墙外保温构造的标准化、规范化提供有益的参考。
[Abstract]:With the improvement of the living standard of our country, people's requirement for the living thermal environment of the building is also increasing, with the building energy consumption rising, and the energy crisis has even become an important factor that affects the sustainable and healthy development of our country's economy. In order to effectively reduce building energy consumption and promote the concept of green building, the development of exterior wall insulation has been paid more and more attention. The common external wall insulation materials in China are field foaming insulation materials, thermal insulation mortar (thermal insulation powder) and thermal insulation plates. However, with the strengthening of people's awareness of environmental protection and the continuous improvement of building energy conservation standards in various places, under the requirements of 75 standards, The thickness of the upper wall of the polystyrene plate is 120mm, and the thickness of the rock wool slab needs to reach 140 mm, which greatly increases the construction difficulty and the construction period, and the increase of the thickness makes the problem of insulation and shedding of the exterior wall which has been criticized by people more worrisome. The original insulation material has not been able to meet the development requirements of energy conservation in China, especially in northern buildings. On the basis of drawing lessons from foreign advanced technologies and through the research and development of many domestic institutions, the ultra-thin vacuum insulation panels used in refrigerators and cold storage boxes were used in the field of building external insulation. Compared with the 60-100mm EPS board, the thermal insulation performance of the ultra-thin vacuum insulation board with thickness of 10-15mm is better. The thermal conductivity is only 0.006w/m K, and the thermal insulation effect is 5 times of that of the conventional polystyrene board and 3 times that of the polyurethane. The thermal insulation performance of the house can be greatly increased, and the fire resistance grade can reach A1 grade. Safety does not burn, and can increase the use of housing area. However, due to the particularity of its insulation principle, it is necessary to ensure that the plate can not be damaged and destroyed in the process of construction and use, which requires higher construction quality. As a new kind of building material for external insulation, the vacuum insulation plate has not yet formed a standardized construction method on the market, and the non-standard construction method is likely to destroy the vacuum insulation plate. The wall insulation performance can not achieve due effect and waste of materials and other problems. Taking the vacuum insulation product of Zhongheng new material as an example, based on the characteristics of the product, construction experience and national building codes and standards, the series of products of vacuum insulation plate are studied in this paper. This paper summarizes and analyzes the products of vacuum insulation plate and the construction requirements of each building node, and selects a building example to carry on the field analysis and research. The article is divided into five chapters: the first chapter is the introduction part, describes the research and application of HVIP vacuum insulation plate at home and abroad, introduces the related concepts such as HVIP vacuum insulation plate, and explains the research content and method of this paper. The second chapter mainly introduces the product series of HVIP vacuum insulation board exterior wall thermal insulation system, and analyzes the merits and demerits of each product and its applicability based on each parameter. In the third chapter, the construction of the external insulation system of different HVIP vacuum insulation panels is studied and designed. The fourth chapter introduces and analyzes a building case of the application of the external insulation system of vacuum adiabatic exterior wall, and expounds the merits and demerits of the external insulation system of the vacuum insulation external wall from the aspects of the design of the construction node, its economy and sociality, etc. It provides a useful reference for the standardization and standardization of external insulation structure of vacuum insulation board.
