End plate connecting joint reinforcing structure and construction method thereof
The invention discloses an end plate connecting joint reinforcing structure and a construction method thereof. The end plate connecting joint reinforcing structure comprises two reinforcing units; the two reinforcing units are symmetrically arranged on the two sides of an existing end plate connecting joint; each reinforcing unit comprises an H-shaped steel component, two stiffening rib plates and two connecting batten plates; the H-shaped steel components are fixedly arranged on the side edges of an existing structural column, and the top ends of the H-shaped steel components abut against the bottoms of existing structural beams; and the stiffening rib plates are symmetrically arranged on the two sides of the existing structural beams, the upper ends of the connecting batten plates are fixedly connected with the stiffening rib plates, and the lower ends of the connecting batten plates are fixedly connected with the H-shaped steel components. By arranging the H-shaped steel components, the rotating rigidity of the existing connecting joint is effectively improved, and vertical force transmission between the existing structural beams is ensured; and by arranging the stiffening rib plates, the local stability of web plates is guaranteed when the existing structural beams transmit vertical concentrated loads, the H-shaped steel components are connected with the stiffening rib plates through the connecting batten plates, and the shear resistance and bending resistance bearing capacity of the existing end plate connecting joint are effectively improved.
本发明公开了一种端板连接节点加固结构及其施工方法，包括两个加固单元；两个加固单元对称设置在既有端板连接节点的两侧；每个加固单元包括H型钢构件、两个加劲肋板及两个连接缀板；H型钢构件固定设置在既有结构柱的侧边，H型钢构件的顶端与既有结构梁底部顶紧设置；加劲肋板对称设置在既有结构梁的两侧，连接缀板的上端与加劲肋板固定连接，下端与H型钢构件固定连接；通过设置H型钢构件，有效提高既有连接节点的转动刚度，确保了既有结构梁与既有结构梁之间的竖向力传递；通过设置加劲肋板，保证了既有结构梁传递竖向集中荷载时腹板的局部稳定性，通过连接缀板将H型钢构件与加劲肋板连接，有效提高了既有端板连接节点的抗剪及抗弯承载力。
