JIN HUAIYIN / XIONG HONGJUN / JIANG FENGPING / ZHAO ZHONGHUA

The invention provides a steel pipe constraint reinforced concrete column reinforcing structure and method, and belongs to the technical field of building structures. The structure comprises a reinforced concrete column and a horizontal reinforced concrete beam, the horizontal reinforced concrete beam is arranged at one end of the reinforced concrete column in the radial direction, the outer side surface of the reinforced concrete column is coated with a constraint steel pipe, and the space between the reinforced concrete column and the constraint steel pipe is filled with a grouting material layer; compared with an existing reinforcing technology, the reinforced concrete column and the horizontal reinforced concrete beam have the advantages that the cross section is not increased, the occupied space is reduced, the structural strength is high, the construction operation is simple and convenient, and the construction period is short.

本发明提供一种钢管约束钢筋混凝土柱加固结构及加固方法，属于建筑结构技术领域。本发明包括钢筋混凝土柱和水平钢筋混凝土梁，水平钢筋混凝土梁沿径向设置在钢筋混凝土柱一端，钢筋混凝土柱外侧表面包覆有约束钢管，钢筋混凝土柱与约束钢管之间填充有灌浆料层，水平钢筋混凝土梁与钢筋混凝土柱连接处梁顶及梁底两端面均设置端板，相邻两块端板之间四角采用对拉螺杆相连接，本发明相比于现有的加固技术，免去了增大截面，减小了占用空间，结构强度高，施工操作简便，施工周期短。
