用钢筋网水泥砂浆面层方法对砌体结构墙体进行抗震加固
|
摘要
砌体结构墙体在地震中破坏严重,但部分结构经加固后仍可继续使用。采用钢筋网水泥砂浆面层方法对砌体结构墙体加固是一种有效的加固方式。文章结合汶川地震中出现裂缝的某教学楼,介绍砌体结构墙体采用钢筋网水泥砂浆面层方法进行加固设计的内容和施工方法,提高砌体结构抗震承载能力,保证结构加固后安全使用,为砌体结构墙体加固提供参考。
The walls of masonry structure were seriously destroied in the earthquake,but some structures could be used all the same after strengthening.It is an effectual strengthening method to masonry structure walls with steel-meshed & cement mortar.The content of strengthening design and the method of construction with the strengthening method is introduced in the paper,using the example of school building cracking in Wenchuan earthquake.The strengthening method can increase the seismic capability of masonry structure,and ensure the building using safely after strengthening.It can supply referrence to strengthening masonry structure walls.
