摘要:随着进入21世纪以及经济的快速发展,中国城市越来越多的建筑已经到了建筑的设计的使用年限,且许多上世纪混凝土结构建筑已不再适应目前新功能的要求,随之而来的是一股建筑维修和加固改造潮。对于混凝土板构件的常规加固方法有增大截面法、体外预应力法、粘贴钢板法等方法;对于新方法更多的是新材料、新工艺的开发,比较新颖的方法有粘贴纤维复合材法、碳纤维布复合法等,例如芳纶纤维(AFRP)等聚合物纤维材料的发明被用于加固领域。41070
本文首先对钢筋混凝土板构件的常规方法和新方法进行了论述,结合混凝土加固相关规范介绍了目前常用的加固方法的设计规定、加固计算理论公式以及构造规定等,之后通过工程案例对各加固方法进行计算分析研究和对比,然后根据加固方法的安全性、经济性、实用性、加固施工及材料费用、施工环境、施工所投入的时间和人力以及抗腐蚀、耐久性等多方面进行深入考虑和分析。最后根据不同施工环境来采取最优的加固方法,争取能为工程应用提供有益的参考。

Ntegration of concrete slab reinforcement methods and economic comparison
Abstract:With the rapid development into the 21st century as well as the economy, China has been building more and more cities to the architectural design of life, and many of the last century building concrete structures no longer meet the current requirements of the new features, followed by It is an architectural repair and reinforcement tide. Conventional methods for reinforcing concrete slab are increasing section method, externally prestressed method, bonded steel plates and other methods; the new method is more new materials, developing new technology, relatively new methods are pasted fiber composite material law , carbon fiber cloth composite method, such as aramid fibers (AFRP) and other polymer fiber material of the present invention is used to reinforce areas.

Firstly, conventional and new methods of reinforced concrete slab were discussed, combined with concrete reinforcement the relevant specification describes the current design requirements commonly used reinforcement methods, reinforcement theory of computation formula and structural requirements, etc., followed by engineering case for each Reinforcement calculation analysis and comparison, then further consideration in accordance with the security reinforcement methods, economic, practical, and cost of materials reinforcement construction, construction environment, construction investment of time and manpower as well as corrosion resistance, durability and other aspects analysis. Finally, according to different construction environment to take the best reinforcement methods, and strive to provide a useful reference for engineering applications.
Keywords: concrete slab, concrete slab reinforcement, reinforcement methods, economic comparison
