一种采用箍筋约束混凝土加固柱的方法
摘要：
一种采用八角箍筋和角部连续圆形螺旋箍筋约束混凝土加固柱的方法，本发明涉及涉及土木工程施工技术领域，具体涉及一种采用八角箍筋和角部连续圆形螺旋箍筋约束混凝土加固柱的方法。本发明是要解决常规增大截面法加固时在柱侧面植入U形筋对原柱造成损伤，继续加载会导致原柱破坏使得U形筋作为箍筋失效，以及加固柱位于楼层之间，难以在加固柱本楼层浇筑混凝土的问题。方法：将通过八角箍筋和四个角部连续圆形螺旋箍筋组合对原柱进行加固，每个八角箍筋由两个完全相同的五折钢筋焊接而成。本发明用于混凝土柱加固领域。
摘要（英）：

The invention relates to the technical field of civil engineering construction, in particular to a method for restraining a concrete reinforcing column by adopting octagonal stirrups and corner continuous round spiral stirrups. According to the method, the problems that when reinforcing is conducted by adopting a conventional section enlarging method, the original column is damaged due to the factthat U-shaped ribs are implanted into the side surface of a column, loading continues to be conducted and consequently the original column is damaged, the U-shaped ribs serve as stirrups and lose theeffect accordingly, and the reinforcing column is located between floors, and consequently concrete is difficult to be poured on the floor of the reinforcing column are solved. According to the method, the original column is reinforced through combination of the octagonal stirrups and the four corner continuous round spiral stirrups, and each octagonal stirrup is formed by welding two identical five-folded steel bars. The method is used for the field of concrete column reinforcing.
