介绍了由玻璃纤维增强水泥单模板与保温材料叠合而成的复合保温模板,作为永久性建筑模板,浇筑混凝土后形成夹芯式复合剪力墙。此类剪力墙不仅具有自保温功能,还可以避免保温层直接接触明火从而降低火灾风险。通过采用不同保温材料、不同种类混凝土及不同材料界面连接方式的相互组合,对不同工况下夹芯式复合试件各界面的抗剪粘结性能及破坏模式进行了研究;对不同界面连接方式、不同保温材料和不同混凝土类型对试件整体抗剪性能的影响进行了对比分析,并提出了使用建议。
介紹瞭由玻璃纖維增彊水泥單模闆與保溫材料疊閤而成的複閤保溫模闆,作為永久性建築模闆,澆築混凝土後形成夾芯式複閤剪力牆。此類剪力牆不僅具有自保溫功能,還可以避免保溫層直接接觸明火從而降低火災風險。通過採用不同保溫材料、不同種類混凝土及不同材料界麵連接方式的相互組閤,對不同工況下夾芯式複閤試件各界麵的抗剪粘結性能及破壞模式進行瞭研究;對不同界麵連接方式、不同保溫材料和不同混凝土類型對試件整體抗剪性能的影響進行瞭對比分析,併提齣瞭使用建議。

A kind of composite?insulation formwork superposed by glass fiber reinforced cement single formwork and thermal insulation materials is introduced, as the permanent building formwork, which is poured with concrete to form a sandwich-type composite shearing wall. This kind of shearing walls not only have the function of self-insulation, but also make the insulation layer avoid direct contact with the open flame so as to reduce the risk of fire. According to the combi-nations of different insulation materials, different types of concrete and different materials interface connection ways, the shearing bond performance and failure modes of the interfaces between composite layers in different conditions are stud-ied, the impact on the shearing behavior of the specimens, which is resulted by the different insulation materials, different types of concrete and different interface connections, is contrasted and discussed, and then some recommendations are pre-sented.
