摘要
建筑物在使用过程中,由于各种灾害和人为损伤等原因,结构功能退化,必须及时予以加固。针对立柱的加固,常用的方法均存在一定的局限性,故而本项目主要研究钢筒套箍内灌浆加固立柱,该加固方法施工简单,便于操作,占用空间小,不影响装修,加固后方柱试件混凝土的承压强度增加了3.1倍,圆柱试件混凝土的承压强度增加了1.3倍。
When a building is still in use, the function of the structure will be reduced due to various disasters and man-made damages. So it is necessary to reinforce the structures. Aimed at reinforcing the columns, there are some limitations for the commonly used reinforcement methods. This paper mainly studies on grouting reinforcement columns with steel cylinder bounded, which is simple and easy to operate, requiring little space, and has no impact on decoration. After reinforcement, the compressive strength of the concrete square column specimens and concrete cylindrical specimens increased by 3. 1 times and 1. 3 times, respectively.
