墙体作为围护结构,由其造成的能量损失占建筑使用消耗能量的三分之二.由于现行墙体保温存在一定的安全隐患,耐久性有待进一步验证,施工技术落后,过程复杂,成本价格高等问题.因此,本文研究了一种由保温材料与围护结构有机结合的新型自保温墙板——陶粒混凝土夹芯保温复合墙板.通过ANSYS有限元软件建立了不同内外叶厚度和不同开洞半径的36个墙板模型,分析了在水平荷载和风荷载作用下的等效应力和位移及墙板的节点温度和传热系数.结果表明:上述36种陶粒混凝土夹芯保温复合墙板均具有良好的力学性能和热工性能,其中4种达到了作为围护结构中保温外墙的河南地区热工性能要求,所有都满足围护结构中保温隔墙的河南地区热工性能要求.
The wall as a retaining structure, the energy loss caused by it accounted for two-thirds of the energy consumption of the building due to the existence of the existing wall insulation there are some security risks, durability to be further verified, the construction technology is backward, the process is complex, the cost price Therefore, this paper studies a new type of self-insulation wallboard-ceramsite concrete sandwich panel which is a combination of thermal insulation material and envelope structure.Through ANSYS finite element software to establish the thickness of the different inner and outer leaves and different 36 wall models with open hole radius and the equivalent stress and displacement under horizontal load and wind load and the node temperature and heat transfer coefficient of the wall panel were analyzed.The results show that the above 36 kinds of ceramsite concrete sandwich thermal insulation composite wall Board have good mechanical properties and thermal performance, of which four reached as the thermal insulation of the envelope in the outer wall of the thermal performance requirements of Henan Province, all of which meet the thermal insulation wall insulation in Henan thermal performance requirements .
