村鎮(zhèn)適用型屋面構(gòu)造設(shè)計與保溫材料評價研究
[Abstract]:At present, the amount of residential construction in villages and towns in China is huge, accounting for more than half of the total amount of residential construction in China; however, due to the backward economy and special geographical characteristics, the level of construction in villages and towns has long been in the stage of backward technology and low level; low building function, high cost, unscientific design, large energy consumption and safety problems are outstanding at present. The common problems existing in the residences of villages and towns not only increase the economic burden on the residents of villages and towns, but also pose a threat to the safety of their lives and property. It is not conducive to the conservation of resources, energy conservation and ecological environment. It also seriously hinders the promotion of the construction of a new socialist countryside and the sustainable development of buildings. One of the important functional parts is another comprehensive system with complete functions besides doors and windows, which plays an important role in building energy saving and safety. Therefore, it is very important to develop economical, practical, functional, safe and environmentally friendly roofs. Therefore, improving the function and safety of residential roofs in villages and towns is an important issue to be solved urgently. This paper takes this as a research starting point and develops from two aspects: the design of applicable flat roof structure and the evaluation and selection of suitable insulation materials for the roofs of villages and towns. In order to further enhance the function and safety of flat roofs in rural areas, this paper firstly expounds the important role of roof structure and roof materials in the safety of rural residential buildings. Roofing form, roofing materials, roof, cost and usage situation, summarize the existing security risks and deficiencies of rural residential roofing in China; finally, in view of the current situation of rural residential roofing, put forward the "village applicable flat roofing" and take the definition of "applicable flat roofing" as a breakthrough point, by drawing lessons from the existing advanced in China. Flat roofing structure and technology, combined with the economic strength of village residents, according to different building thermal design zoning, respectively hot summer and warm winter area, hot summer and cold winter area, cold area and cold area suitable flat roofing structure design, respectively, from the economic, practical, functional, safety and environmental protection point of view to reflect the "applicable flat roofing" Finally, in view of the current situation of a wide variety of roofing materials and mixed fish and dragon, this paper combines the economic conditions and the actual situation in rural areas, selects the VRS model of DEA model as the evaluation model of the suitable insulation materials for the roof of villages and towns; according to the evaluation index survey questionnaire statistics, according to the comprehensive evaluation index The evaluation principle of the system determines the evaluation index of the suitable thermal insulation for the roof of villages and towns, i.e. the five indexes of economy, energy saving, environmental protection, health and safety are taken as the evaluation index of the suitable thermal insulation materials for the roof of villages and towns, and the comprehensive evaluation system of the safe roof materials of villages and towns is established according to the evaluation indexes, and the VRS model of DEAP2.1 software DEA is adopted. The results show that the decision-making unit DEA of hydrophobic expanded perlite, hydrophobic rock wool board and glass wool board is the most effective, which can be used as insulation material for village roof, followed by polystyrene board, and polyurethane products are not suitable for village roof. Through the study on the structural design of the applicable flat roof and the evaluation and selection of the roof insulation materials, the function and safety of the roof can be ensured, the economic burden of the residents in the villages and towns can be reduced, the advanced roofing technology can be provided for the construction of the houses in the villages and towns, the roofing construction of the houses in the villages and towns can be guided, and the construction and construction of the houses in the new socialist countryside can be promoted. Sustainable development of construction is of great significance.
