楼面梁裂缝的加固设计与施工

结构物裂缝是一个带有普遍性的技术问题,结构的破坏大多是从裂缝的扩展开始的,所以人们对裂缝往往产生一种破坏前的恐惧感。的确,从固体强度理论的发展可以看到裂缝的扩展是结构物破坏的初始阶段,结构的承载力将受到一定的威胁,且结构的持久强度也会降低。文章以一个实物为例,从钢筋砼结构裂缝的原因分析、加固设计、补强施工等方面作出总结,为大家认识结构物裂缝及其处理提供了依据。

Design and Construction of the Reinforcement of Floor Beam Cracks

Structure cracks are a universal technical problem,the destruction of structures mostly starts from crack expansions,so people often fear cracks before the destruction.Indeed,from the development of the theory of solid strength,expansions of cracks may been seen as the starting phase of structure destruction,the carrying capacity will be threatened and the durability will be reduced.This article,using a specific example,has summarized the cause analysis,reinforcement design,make-up construction of cracks in concrete structures,which can be used as a reference of people to understrand cracks and treatment better.
