【摘要】：建筑节能建设是一个全球研究性潮流,建筑物节能设计是我国现阶段尚待深度研究的最前沿的应用型课题之一。开发满足产业化生产要求的,标准化和工业化程度高、施工质量优良、符合可持续发展要求、经济友好性的新型工业化住宅体系,已经成为我国现阶段的首要工作任务。改善围护结构的保温隔热性能是推动建筑节能建设的重要途径。随着建筑业的高度发展,各种新型墙体保温材料和节能住宅建筑体系也随之发展起来。但由于新型墙体保温材料和节能住宅建筑体系在应用上受到了很大的限制,还存在着如使用耐久性较差、经济性差、腐蚀老化以及冷桥现象严重等很多弊端,所以很难推广使用。因此,如何寻求一种新型的夹芯保温复合墙板体结构形式,在保留和发扬传统夹芯保温复合墙板体既有优势的同时,又能解决长久以来制约夹芯保温复合墙板体推广使用的诸项弊端就成为了推广住宅产业化中的一项重要研究工作。本文设计研究了一种最适用于夏热冬地区使用的节能保温夹芯墙板,集承重、保温功能为一体的建筑结构性能优良的节能墙板的主要特性。本文首先对2组受弯试件进行了结构静力加载试验,观察保温墙板的荷载-挠度变化曲线、裂缝开展情况、最大破坏荷载等性能；然后对相同尺寸的受弯性墙板试件,在运用(ANSYS)有限元软件对其进行非线性有限元建模分析,将有限元分析结果与试验结果进行对比,对比结果表明该保温复合墙板具有很好的塑性变形能力、可以作为承重构件,满足围护结构墙板的使用要求。其次,为研究该种保温性墙板的受压性能,对不等厚度面板的夹心保温板试件,利用(ANSYS)有限元分析软件对其进行非线性有限元建模分析,结果表明该种保温复合墙板具有良好的抗压承载能力可以满足墙板的使用功能。最后,为研究该种保温复合墙板的保温性能,对其进行了2组热工性能试验,并将试验结果与有限元分析结果进行对比,对比结果表明该种墙板的保温隔热性能优良,满足夏热冬冷地区的节能设计标准的要求。
[Abstract]:Study on the construction of energy-efficient is a global trend, building energy-saving design is one of the most advanced application subject in the present stage of our country remains to be studied. The depth of development to meet the requirement of the industrial production, standardization and high degree of industrialization, the construction of good quality, meet the requirements of sustainable development, new industrialization of residential system of economic friendliness that has become the primary task of the present stage of our country. To improve the thermal insulation performance of building envelope is an important way to promote the construction of energy-saving construction. With the development of the construction industry, a variety of new wall insulation materials and energy-saving residential building system is also developed. But because of new wall insulation materials and energy-saving residential building system is very limited in application, there exist such as poor durability, poor corrosion, aging and cold bridge phenomenon is serious and many disadvantages, the It is difficult to use. Therefore, how to seek a new type of sandwich structure composite wall body heat preservation, keep and carry forward the traditional insulation sandwich composite wall body has advantages at the same time, but also can solve the long-standing constraints of sandwich wall body to promote the use of the malpractice has become an important research promotion in the housing industry.
In this paper, a main energy-saving and thermal insulation sandwich wall panel, which is suitable for hot summer and winter area, is designed and researched. The main characteristics of the energy-saving wall with excellent architectural performance and good thermal insulation function are integrated.
Firstly, 2 groups of bending specimens were static loading test, load observation of wall insulation deflection curve, crack, the maximum failure load performance; and then the same size of the bending of wall panel, using finite element analysis software (ANSYS) nonlinear finite element modeling of the and the finite element analysis results were compared with the experimental results. The comparison results show that the thermal insulation composite wall with plastic deformation ability is very good, can be used as load-bearing components, to meet the use requirements. Wall retaining structure
Secondly, to study the thermal insulation wall compression performances of unequal thickness panel sandwich insulation plate specimens, using finite element analysis software (ANSYS) nonlinear finite element analysis on the modeling, the experimental results show that the thermal insulation composite wall has good compressive bearing capacity can satisfy the wall function.
Finally, on the thermal insulation performance of composite wallboard, the 2 groups of the thermal performance test, and the test results were compared with the results of finite element analysis, the comparative results show that the heat insulation performance of the wallboard is excellent, meet the energy-saving in hot summer and cold winter area design standards.
