【摘要】：建筑保温是建筑节能和低碳减排的根本途径。目前建筑保温通行有机材料EPS、XPS等,但因其均属于易燃物质、多次引发火灾,同时寿命短、易变形,亟需寻找替代产品。超轻泡沫混凝土作为理想的无机阻燃保温材料,应用前景广阔,但因其导热系数较高、缺乏必要的设计规范和标准,在建筑保温市场尚未得到推广。本文从建筑设计的角度出发,对超轻泡沫混凝土保温材料的热工性能、构造做法、适用范围进行研究,以期寻找适合其应用的建筑保温做法、适用区域及应用途径,从而推动超轻泡沫混凝土的建筑保温应用。本文首先通过调研了解目前市场上新型料超轻泡沫混凝土保温板的应用现状,特别是从建筑设计环节,分析得出其难以推广主要是因为设计过程缺乏必要的标准规范以及具体应用的构造做法和应用途径;之后采用数值模拟的方法,借助能耗模拟软件,对超轻泡沫混凝土保温材料在不同的气候分区、以不同的窗墙比和体型系数,模拟研究该材料的热工性能对建筑能耗的影响,为建筑设计单位以及制定规范标准的有关部门提供基础性资料。通过与有机保温材料膨胀聚苯板(EPS)在综合能耗、全年动态热、冷负荷等方面数据的系统对比,给出在寒冷地区和夏热冬冷地区,典型公共建筑外围护结构保温设计中的基本参数。本文的研究证明,超轻泡沫混凝土保温板尽管其保温性能稍逊于EPS保温板,但是具有更好的蓄热性能,尤其在屋顶保温方面,具有很好的热工性能;特别对于防火等级要求高的公共建筑,其应用效果具有较大优势。本文的研究成果为超轻泡沫混凝土保温板的推广应用提供了基本的建筑设计方法、量化依据和基本参数,为建设单位采用此种保温技术提供可靠的数据支持,并可促进相关规范标准的建立与完善。
[Abstract]:Building insulation is the fundamental way of building energy saving and low carbon emission reduction. At present, organic materials, such as EPS / XPS, are widely used in buildings, but because they are flammable materials, they cause fire many times, and their life is short and easy to deform, so it is urgent to find alternative products. As an ideal inorganic flame retardant insulation material, ultra-light foamed concrete has a broad application prospect, but because of its high thermal conductivity and lack of necessary design specifications and standards, it has not been popularized in the building insulation market. From the point of view of architectural design, this paper studies the thermal properties, construction practices and applicable scope of ultra-light foamed concrete insulation materials, in order to find suitable building insulation practices, applicable areas and application ways for their application. Thus, the application of building insulation of super light foam concrete is promoted. In this paper, first of all, through investigation and research, we understand the current situation of the application of the new type of ultra-light foamed concrete insulation board in the market, especially from the aspects of architectural design. The analysis shows that it is difficult to be popularized mainly because the design process lacks the necessary standard specification, the concrete application construction method and the application way, and then uses the numerical simulation method, with the aid of the energy consumption simulation software, The influence of thermal properties of ultra-light foamed concrete insulation material on building energy consumption is simulated with different window / wall ratio and shape coefficient in different climate zones. To provide basic information for architectural design units and relevant departments that formulate specifications and standards. By comparing the data of comprehensive energy consumption, year-round dynamic heat and cooling load with organic thermal insulation material EPS, the paper gives out the data in cold area and hot summer and cold winter area. The basic parameters of the thermal insulation design of the exterior envelope of typical public buildings. The research in this paper proves that although the thermal insulation performance of ultra-light foam concrete insulation board is slightly inferior to that of EPS thermal insulation board, it has better thermal storage performance, especially in the aspect of roof insulation, it has very good thermal performance. Especially for public buildings with high fire-proof grade, its application effect has great advantages. The research results of this paper provide the basic architectural design method, quantitative basis and basic parameters for the popularization and application of ultra-light foamed concrete thermal insulation board, and provide reliable data support for the construction unit to adopt this kind of insulation technology. And can promote the establishment and improvement of relevant standards.
