摘　　要：以石墨改性模塑聚苯板为保温芯材制作点连式保温结构一体化复合剪力墙,保温层厚度100~400 mm;连接件分为碳钢、不锈钢和玻纤3种材质,碳钢和不锈钢连接件分别进行了不同程度的塑料包裹加工。测试了不同保温层厚度及不同连接件实验墙的实际平均传热系数。结果表明:对于碳钢连接件,部分塑料包裹可以明显改善其对围护结构热阻带来的不利影响,全塑料包裹相比部分塑料包裹略有改善。不锈钢连接件塑料包裹处理后,对热阻的不利影响也随部分和全部包裹处理略有改善。保温层厚度相同时,保温材料导热系数的修正系数排序为:碳钢连接件体系>不锈钢连接件体系>玻纤连接件体系。Using graphite modified polystryrene boards as insulation core materials to produce integrated composite shear walls with point connected insulation structures,and the insulation thickness varies from 100 mm to 400 mm.There are three kinds of connector materials:carbon steel,stainless steel and glass fiber.Carbon steel and stainless steel joints are wrapped in plastic to different degrees.The actual average heat transfer coefficients of different insulation thickness and different connectors are tested.The results show that for carbon steel connections,part plastic parcels can significantly improve the adverse effects on the thermal resistance of the envelope,and all plastic parcels are slightly improved compared with part plastic parcels.After plastic wrapping treatment of stainless steel connector,the adverse effects on thermal resistance are slightly improved with part and all wrapping treatment.When the insulation thickness is same,the correction coefficient of thermal conductivity of insulation material sorting:carbon steel connector system>stainless steel connector system>glass fiber connector system.
