混凝土夹芯复合墙板热工性能研究

摘要

结合浙江省等夏热冬冷地区的节能设计标准,研究开发了一种自保温混凝土夹芯复合墙板,并重点研究了混凝土夹芯复合墙板在不同保温层厚度、斜向钢筋含量和混凝土层厚度情况下,其热工性能指标的变化规律.结果表明,在不采取额外保温措施的情况下,混凝土夹芯复合墙板的热工性能能满足夏热冬冷地区节能设计标准要求.研究成果与实际工程联系紧密,具有较高的实用价值.%In combination with the standard of energy conservation in the Hot Summer and Cold Winter Regiona like Zhejiang Province,a kind of aelf-insulation reinforced concrete sandwich wall-panel is exploited Influence on thermal performances of reinforce concrete sandwich wall-panel,due to the difference in thickness of concrete layer,the thickness of heat insulation layer and the ratio of oblique tie bar,are analyzed. The investigation reveals that under the condition of not taking additional thermal insulation measures the thermal performances of concrete wall-panel meet the requirements of standard of energy conservation in the Hot Summer and Cold Winter Regions. The findings of this paper are tightly related to the engineering practice and have relatively higher use value
