摘 要:为了更好地验证桥梁加固用环氧树脂胶粘剂性能,现利用桥梁填料工艺,通过利用硅微粉、高岭土、膨润土、滑石粉、碳酸钙、水泥和粉煤灰7种不同桥梁填料配置环氧树脂胶粘剂,然后,将该胶粘剂分别放置在3种不同施工环境下,研究钢对钢拉伸剪切强度的具体影响,在此基础上,根据7种桥梁填料主要成分、密度以及环氧树脂的特点,全面分析钢对钢拉伸剪切强度的影响因素,并针对环氧树脂胶粘剂性能,选出合适的环氧树脂胶粘剂填料,以保证桥梁结构的稳定性、可靠性和安全性。结果表明,在桥梁填料工艺下,桥梁加固用环氧树脂胶粘剂具有良好的性能,被广泛地应用于桥梁结构的设计和优化中,为保证桥梁结构的坚固性和稳定性提供有力的保障。

Abstract:In order to better verify the performance of epoxy resin adhesive for bridge reinforcement, the bridge filler technology is used to prepare epoxy resin adhesive by using seven different bridge fillers, namely, silica powder, kaolin, bentonite, talc powder, calcium carbonate, cement and fly ash, and then the adhesive is placed in three different construction environments to study the tensile shear strength of steel to steel On this basis, according to the main composition, density and the characteristics of epoxy resin of seven kinds of bridge fillers, the influencing factors of steel to steel tensile shear strength are comprehensively analyzed, and according to the performance of epoxy resin adhesive, the appropriate epoxy resin adhesive filler is selected to ensure the stability, reliability and safety of bridge structure. The results show that the epoxy resin adhesive for bridge reinforcement has good performance under the bridge filler technology, and is widely used in the design and optimization of bridge structure, which provides a strong guarantee for the firmness and stability of bridge structure.
