【摘要】：近年来,随着我国各类能源需求量的不断增加,而能量生产增长的速度远远低于建筑耗能的增长速度,节能环保特别是建筑节能工作已经成为我国国民经济可持续发展的重大课题。在整个建筑耗能中围护结构热传导所引起的能耗所占比重较大,而墙体是建筑物中不可缺少的围护结构,墙体材料的革新和保温技术必须满足建筑节能的要求,墙体建筑节能则须基于新型墙体材料和先进的保温技术。掺废渣土烧结页岩保温砌块(下文简称SSCW保温砌块)是以页岩、建筑废渣土、粉煤灰等为主要原料,经过粉碎、混合、挤压、磨具成型等多道工序烧结而成多排孔保温砌块,在湖南省等夏热冬冷地区采用该种砌块作为非承重外墙即使不添加其他保温材料也可以达到建筑节能目标。本文以试验为依据,并结合软件模拟分析,综合研究分析了SSCW保温砌块的保温隔热性能及其砌块砌体的力学性能等各项基本性能,为该砌块的推广和使用提供理论依据。本文的主要工作和结论如下:(1)本文从墙体保温隔热的性能和工程应用等方面出发,对砌块块体、规格、孔型、孔洞率和孔洞排列方式等方面进行了分析,设计出能够满足建筑节能要求SSCW保温砌块;(2)通过FLUENT和ANSYS两种软件对本文所设计的SSCW保温砌块同三种常见孔型的砌块分别进行热工性能和单砖应力对比分析,得出了SSCW保温砌块各方面性能优于其他三种常见孔型的砌块;(3)通过试验对SSCW保温砌块的基本力学性能进行研究,包括块体强度试验研究、砌体的抗压和抗剪强度的测定;(4)通过一个工程实例对SSCW保温砌块砌体房屋和普通粘土砖房屋的节能和经济两个方面进行了对比分析,认为SSCW保温砌块适合在湖南省等各夏热冬冷地区推广使用。
[Abstract]:In recent years, with the continuous increase of energy demand in China, the growth rate of energy production is far lower than the growth rate of energy consumption in construction. Energy saving and environmental protection, especially building energy conservation, has become a major issue for the sustainable development of our national economy. In the whole building energy consumption, the energy consumption caused by the heat conduction of the envelope structure accounts for a large proportion. The wall is an indispensable enclosure in the building, the wall material innovation and insulation technology must meet the requirements of building energy conservation. The energy saving of wall building should be based on new wall materials and advanced heat preservation technology. Sintered shale insulation block (hereinafter referred to as SSCW insulation block) with waste slag soil is shale, construction waste slag soil. Fly ash is the main raw material, after crushing, mixing, extrusion, grinding tool forming and other multi-process sintering into multi-row hole insulation block. In the hot summer and cold winter area of Hunan Province, this kind of block can be used as non-load-bearing external wall to achieve the goal of building energy saving even without adding other thermal insulation materials. This paper is based on the test and combined with software simulation analysis. The thermal insulation properties of SSCW insulation block and the mechanical properties of block masonry are studied and analyzed comprehensively. The main work and conclusions of this paper are as follows: 1) this paper starts from the performance of wall insulation and engineering application, to block blocks, specifications, holes. The hole rate and the arrangement of the holes are analyzed, and the SSCW insulation block can be designed to meet the requirements of building energy saving. Through FLUENT and ANSYS software, the thermal properties and single brick stress of the SSCW insulation block and three kinds of common hole blocks designed in this paper are compared and analyzed respectively. It is concluded that the performance of SSCW insulation block is better than that of the other three kinds of common hole blocks. 3) the basic mechanical properties of SSCW thermal insulation block are studied by test, including block strength test, masonry compressive and shear strength measurement; Through an engineering example, the energy saving and economic aspects of SSCW insulation block masonry building and ordinary clay brick house are compared and analyzed. It is considered that SSCW insulation block is suitable for popularizing in Hunan province in hot summer and cold winter.
