WU CHENCHEN / ZHAN ZHIYONG / XU KE / YU SUYANG

The invention provides a reinforcing method of a concrete column. The reinforcing method comprises the following steps of: vertically driving a plurality of anchor bolts into the concrete column at apreset position of the concrete column, wherein one end of each anchor bolt is positioned outside the concrete column; mounting a steel sleeve, sleeving the steel sleeve on the concrete column, forming a gap between the steel sleeve and the concrete column to form a filling area, and connecting one end, positioned outside the concrete column, of each anchor bolt with the steel sleeve; arranging abaffle below the steel sleeve to cover the bottom of the filling area; and injecting a binder into the filling area to bond the steel sleeve and the concrete column. The bearing strength of the concrete column is improved by driving the anchor bolts, and the safe use of the concrete column is guaranteed. Moreover, the stress among the anchor bolts can be balanced by arranging the steel sleeve outside the concrete column. The reinforcing method of the concrete column provided by the invention also has the advantages of simple construction steps, high construction efficiency, low construction cost and the like.

本发明提供了一种混凝土柱的加固方法，包括：在一混凝土柱的预设位置处，将若干锚栓垂直打入所述混凝土柱内，且所述锚栓的一端位于所述混凝土柱外；安装一钢套，使所述钢套套设在所述混凝土柱上，且所述钢套与所述混凝土柱之间具有间隙以形成一填充区，将所述锚栓位于所述混凝土柱外的一端与所述钢套连接；在所述钢套的下方设置挡板以覆盖所述填充区的底部；往所述填充区内注入粘结剂以粘结所述钢套与所述混凝土柱。通过打入锚栓以增加混凝土柱的承载强度，保证混凝土柱的安全使用。并且，通过在混凝土柱外设置钢套能够平衡各个锚栓之间的受力。本发明提供的混凝土柱的加固方法还具有施工步骤简单、施工效率高以及施工成本低等优点。
