近年来我国公路建设发展迅猛,但由于年久失修,以及设计荷载标准低等原因,在役桥梁中很大一部分正在逐步成为危桥,需要对旧桥进行适当的加固和改造。锚贴钢板加固是是在混凝土构件外部用专用异型铆钉将钢板锚贴于构件表面,以提高其承载能力的一种新型加固补强方法。文章介绍了锚贴钢板加固技术的特点和施工工艺,并通过工程实例详细阐述了锚贴钢板加固技术在桥梁加固工程中的应用。
In recent years, the rapid development of highway construction in our country, but due to disrepair, and the design of low load standards and other reasons, a large part of the existing bridge is gradually becoming a dangerous bridge, the need for the appropriate reinforcement and transformation of the old bridge. Anchoring steel plate reinforcement is a new type of reinforcing and reinforcing method which is to attach the steel plate anchor to the surface of the component with special shaped rivets on the exterior of the concrete component to enhance its carrying capacity. This paper introduces the characteristics and construction technology of anchoring steel plate reinforcement technology, and expounds the application of anchorage steel plate reinforcement technology in the bridge reinforcement project through engineering examples.
