摘要
为了改进粘钢加固用结构胶的力学性能,对结构胶的各个构成组分进行试验分析确定其用量比例,通过室内试验和力学性能测试研究粘钢加固用结构胶的力学性能特点。采用正交试验得出结构胶各个组分对力学性能影响的主次顺序,确定了粘钢加固用结构胶的配比。通过分析不同固化剂用量对结构胶的性能影响,确定固化剂用量,并对试配的结构胶进行了力学性能试验,得出的力学性能指标满足粘钢加固用结构胶的使用要求,试配的结构胶可以用于混凝土桥梁的加固补强。另外,对适配的结构胶在使用过程中的表面处理、固化时间、固化温度与相对湿度、固化压力提出了指导性建议研究方法,可为桥梁结构的加固提供借鉴意义。
In order to improve the mechanical performance of the structural adhesives for bridge structure members strengthening with bonded steel plate, the composition of the structural adhesive was experimental analyzed to determine its proportion. The mechanical performance of the structural adhesive was studied through laboratory and mechanical tests. The primary and secondary sequences of the influence of various components of the structural adhesive on the mechanical performance was obtained by orthogonal test, and then the proportion of the structural adhesive for structure member strengthening with bonded steel plate was determined. By analyzing the influence of amount of curing agent on the structural adhesive properties, the amount of curing agent was determined. Then the mechanical performance of the trial structural adhesive was tested, which can meet the requirements of structure member strengthening with bonded steel plate. The trial structural adhesive can be used to reinforce the concrete bridge. Besides, the suggestions on surface treatment, curing time, curing temperature and relative humidity, and curing pressure in the process of using this structural adhesive were put forward, which is helpful for reinforcement of bridge structures.
