碳纤维布加固砖砌体结构新技术研究

Study of New Technology for Carbon Fiber Sheet Reinforcement Brick Masonry Structure

结合北京石景山区某教学楼加固工程实例,详细介绍了碳纤维材料加固砖砌体结构的设计方案,提出了材料性能要求,系统总结了施工程序和施工要点,对同类工程加固有指导意义。采用碳纤维材料加固砖砌体结构可以明显提高抗震能力,碳纤维布加固砖砌体施工工艺简单、操作方便、噪声小、施工扬尘少、不占据室内空间、投资合理、工期短,在结构加固领域具有良好的发展前景。

Based on a reinforcement project of a teaching building in Shi Jingshan District in Beijing,the paper present the detailed design scheme of Carbon Fiber Sheet reinforcement brick masonry structure,proposed demands of material performances,systematically summarized the construction procedure and the construction essential, which have guiding significance for similar reinforcement projects.The seismic capacity of the brick masonry structure can be significandy improved with carbon fiber reinforcement.The carbon fiber sheet reinforcement method has the advantages such as simple construction process,easy operation,low noise,less construction dust,non-occupying the interior space,reasonable investment and short construction period which make a good prospect for development in the field of structural reinforcement.
