摘要
为了评价新型建筑-木塑活动房设计与施工的合理性,采用Fluke Ti45红外热像仪对其热工缺陷进行了定性研究。通过对大量红外热图的观察,发现该木塑活动房屋顶周围与墙体上端的接合部位、钢结构与保温材料接缝部位、保温材料与保温材料之间的缝隙等都是热量易通过与散失的部位;沿着西墙纵向安装的钢结构处发生了渗漏现象,保温材料严重受潮。今后设计这一系列木塑房屋时,要重点考虑这些部位,以防止漏热、渗水现象的发生。
In order to evaluate the rationality of design and construction for the new built-wood-plastic composite prefabricated house,infrared thermal imager（Fluke Ti45） was used to qualitatively study the thermodynamic defect.Through lots of infrared thermal images,it can be found that the joint place at the roof and the top of the walls,joints on the steel structure and insulation materials,as well as the gaps between the insulation materials are the places of heat leakage;leakage occurs along the longitudinal steel structure in the west wall,which lead to the damp of insulation materials seriously.In the future,attentation should be paid on these parts to prevent the phenomenon of the heat leakage and ooze when this series of wood-plastic composite prefabricated house is designed.
