摘  要:改善室内外热环境、提高建筑宜居性、促进建筑节能减排,是建筑行业实现可持续发展的重要路径,也是响应我国双碳目标的关键举措。分析了常用外保温系统的特点和保温层剥落原因,重点采用工程水泥基复合材料(ECC)与聚苯乙烯板(EPS)制备夹心复合墙板试件,并研究了保温材料厚度、连接件及其嵌入角度对保温层界面剪切粘接强度的影响,结果表明:增加保温层厚度,试件粘接强度会降低,保温层最佳厚度为50 mm;使用连接件后试件的力学性能更加优良,当其嵌入角度为45°时,试件的抗剪粘接强度最高。Improving the indoor and outdoor thermal environment,improving the livability of buildings,and promoting building energy conservation and emission reduction are important paths for the construction industry to achieve sustainable development,and they are also key measures to respond to China’s dual carbon goals.The characteristics of the commonly used external thermal insulation system and the causes of the spalling of the insulation layer were analyzed,and the sandwich composite wallboard specimens were prepared by engineering cement-based composite materials(ECC)and polystyrene board(EPS),and the effects of the thickness of the insulation material,the connector and its embedding angle on the interfacial shear bonding strength of the insulation layer were studied,and the results showed that the adhesive strength of the specimen would decrease with increasing the thickness of the insulation layer,and the optimal thickness of the insulation layer was 50 mm.The mechanical properties of the specimen were better when the connector was used,and the shear bonding strength of the specimen was the highest when the embedding angle was 45°.
