高温下正交胶合木胶黏剂性能研究进展

Research Progress in Cross-laminated Timber Adhesive Properties at Elevated Temperatures

正交胶合木(CLT)作为楼盖、墙体构件,广泛用于中高层木结构建筑。建筑防火是建筑设计中的重要领域,CLT防火性能与所使用胶黏剂密切相关,高温下胶黏剂胶合性能下降将影响CLT的耐火性能。介绍了目前高温下CLT胶黏剂性能的研究进展及测试方法,以期为国内对高温下CLT胶黏剂性能的研究提供参考。

Cross-laminated timber(CLT)is widely used in middle-and high-rise timber structural buildings as flooring and wall components.Building fire protection is an important part in building design.The fire resistance of CLT is closely related to the used adhesives.The degradation of adhesives at elevated temperature will affect the fire resistance of CLT.This paper mainly introduces the current research progress and test methods for the performance of CLT adhesives at elevated temperatures with the aim to provide reference for domestic research on the properties of CLT adhesives at elevated temperature.
