加固是指对可靠性不足或业主要求提高可靠度的承重结构、构件及其相关部分采取增强、局部更换或调整其内力等措施,使其具有现行设计规范及业主所要求的安全性、耐久性和适用性。建筑结构因设计不当、混凝土强度偏低、结构受力钢筋配置不足、改变使用功能和增强荷载、混凝土构件产生裂缝、工程拆除加建等,造成建筑结构达不到设计要求,需对承重结构、构件及其相关部分采取补强加固技术措施。
Reinforcement refers to the lack of reliability or the owners require to improve the reliability of the load-bearing structure, components and related parts to enhance the local replacement or adjustment of its internal forces and other measures to make it with the current design specifications and the owners of the required safety, durability And applicability. Due to improper design of the building structure, the concrete strength is low, the structure of the reinforced steel configuration is not enough to change the use of features and enhance the load, cracks in concrete structures, construction demolition and construction, resulting in less than the design requirements of the building structure, the load-bearing structure, Components and related parts to take reinforcement and reinforcement measures.
