摘　　要：随着经济建设的发展,大量旧有建筑需要加固改造,而植筋作为后锚固技术的一种,被广泛应用于加固改造工程中。在实际工程中,许多植筋构件存在着火灾的风险,考虑到无机材料具有良好的耐高温性能,因此对无机植筋胶进行深入的研究具有显著的经济效益和社会效益。为了研究无机胶植筋构件的耐高温性能,进行了无机胶与有机胶植筋真实火灾的对比试验。在设计试件时,考虑了锚固深度和植筋胶种类两种影响因素。试验结果表明:在火灾作用下有机胶植筋最终将发生锚固破坏,破坏较突然;无机胶植筋的构件在火灾作用下力学性能表现良好,并没有发生锚固破坏。With the development of economy and construction, a large number of old buildings need reinforced and retrofitted. As one of post-installed fastenings, post-installed rebars are widely used in reinforcement and reconstruction engineering. In practical engineering, many anchorage components may be at the risk of fire. Considering the inorganic material having a good high temperature performance, the experimental study can bring significant economic and social benefits. A serial of fire tests has been conducted to study the fire behavior of anchorage components with organic and inorganic adhesive. The two factors are considered in the tests. The test results show that beams using organic adhesive failed suddenly, while using inorganic adhesive, anchor damage didn＇ t occur under fire.
