碳纤维布在某改造工程预制楼板加固中的应用

The Applications of Carbon Cloth in the Reinforcement of Precast Floor Slab of a Reconstructed Engineering

碳纤维加固是一项新兴技术,文章详细介绍了该技术在某改造工程中的应用。利用碳纤维布对预制楼板进行加固,存在荷载增加、预应力钢筋被打断等不利因素,但预制楼板能够满足承载力要求。这一突出优点使碳纤维布加固混凝土结构可以替代粘钢技术在建筑物、桥梁加固工程中推广,其应用前景良好。

Precast floor slab reinforcement is a new technique.The paper introduces its application in a reconstructed engineering. Applying carbon cloth to reinforce precast floor slab has some disadvantages,for example the load adds and prestressed reinforcement bars are broken down.However,precast floor slab can satisfy the needs of load.This advantage can make the concrete structure reinforced by carbon cloth replace stick steel strengthening and can be promoted in construction and bridge reinforcement projects,which has promising applications.
