Method for reinforcing concrete beam-column joint with insufficient anchoring bearing capacity
The invention discloses a method for reinforcing a concrete beam-column joint with insufficient anchoring bearing capacity, and particularly relates to a reinforcing method for improving the anchoring bearing capacity of a beam main reinforcement in a side joint in a manner of additionally arranging a brick wing wall and a reinforced concrete wall end column on the inner side of an existing structural column so as to improve the integrity of a concrete frame. According to the brick wall building, red bricks and cement mortar are used for building wing walls in rectangular spaces formed by wall end columns and beams and columns of an existing structure of a building wall, a standard brick wall building mode is adopted as the wall building mode, and mortar is filled in gaps between the bricks and gaps between the bricks and surrounding structures. The wall end column is obtained through drilling, steel bar planting, welding of planted steel bars and constructional column main steel bars, stirrup binding, concrete formwork manufacturing, concrete pouring and curing, and the problems that an existing concrete beam-column joint anti-seismic structure reinforcing technology is complex in technology, high in manufacturing cost and the like are solved, and a reinforcing method for beam-column joints with insufficient anchoring bearing capacity does not exist are solved.
本发明公开了一种加固锚固承载力不足混凝土梁柱节点的方法，通过在既有结构柱的内侧增设砖砌翼墙与钢筋混凝土墙端柱的方式提升梁主筋在边节点内的锚固承载力，进而提升混凝土框架整体性的加固方法，砌砖墙为在墙端柱与建筑墙体既有结构的梁、柱形成的矩形空间内使用红砖、水泥砂浆砌筑翼墙，砌墙方式采用砖墙的标准砌筑方式，砖块间、砖块与周围结构间的缝隙填充砂浆；墙端柱通过钻孔、植筋、植筋与构造柱主筋焊接、箍筋绑扎、混凝土模板制作、混凝土浇筑及养护得到，解决了现有的混凝土梁柱节点抗震结构加固技术存在技术复杂、造价高等缺陷，且未见针对锚固承载力不足梁柱节点的加固方法的问题。
