结构胶在地铁车站建设中的应用研究

Research on Application of Structural Adhesive in the Construction of Metro Station

文章介绍了结构胶在国内的现状及应用范围,通过对结构胶优势的研究,重点分析了结构胶在地铁车站中的应用,结构胶可用来在地铁站建设中加固车站墙体,提高车站墙体稳固性。结构胶通过粘结钢材结构,加固钢筋混凝土结构,提高车站钢筋混凝土结构耐用性,克服因长期使用导致的老化、开裂等缺陷。结构胶还应用在地铁车站梁柱及墙体裂缝修复中,常用的JGN等多种型号结构胶用于裂缝修复,具有工艺效果好,粘结强度高,固化时间短,适应性强等多种优点。最后对结构胶的发展做了展望。

The current situation and application scope of structural adhesives in China are introduced.Through the study of the advantages of structural adhesives,the application of structural adhesives in subway stations is mainly analyzed.Structural adhesives can be used to strengthen the station wall and improve the stability of the station wall.Structural adhesive can strengthen the reinforced concrete structure by bonding the steel structure,improve the du⁃rability of the reinforced concrete structure of the station,and overcome the aging and cracking defects caused by long-term use.Structural adhesives are also used in crack repairing of beams,columns and walls of subway stations.Various types of structural adhesives such as JGN are commonly used for crack repairing.It has many advantages such as good process effect,high bonding strength,short curing time and strong adaptability.Finally,the develop⁃ment of structural adhesive is prospected.
