Construction method and reinforcing device for enlarging and reinforcing section of existing structural beam
The invention discloses a construction method for increasing and reinforcing the section of an existing structural beam and a reinforcing device. The construction method comprises the following steps: S1, chiseling an original main beam; s2, main reinforcement and waist reinforcement planting is conducted on the columns at the two ends, and the positions of adjacent reinforcement joints are staggered; s3, the stirrups are embedded and anchored into the beam, specifically, according to a certain interval in the length direction of the main beam, the tops of the U-shaped stirrups of the newly-added section beam are embedded into the main beam according to the designed anchoring requirement, the U-shaped stirrups of the newly-added section beam surround the main beam, and a certain gap is formed between the U-shaped stirrups of the newly-added section beam and the main beam so that the section of the main beam can be increased; s4, binding waist bars; s5, binding the main reinforcements; and S6, upper hogging moment main reinforcement synchronous construction is conducted, specifically, newly-added hogging moment reinforcements at the beam top are planted on columns at the two ends and close to a floor slab, newly-added inverted-U-shaped stirrups are planted into the floor slab in a rib buckling mode, the hogging moment reinforcements added on the upper portion can be independently poured, and the section of the existing structural beam is increased through the steps.
本发明公开一种既有结构梁截面增大加固的施工方法及加固装置，包括：S1、原有主梁凿毛；S2、在两端柱子进行主筋腰筋植筋，相邻钢筋接头位置错开；S3、箍筋植筋锚入梁内：沿着主梁的长度方向按照一定间距，贴着主梁底部避开主梁内主筋钻孔，将新增截面梁U型箍筋的顶部按设计锚固要求植入主梁内，新增截面梁U型箍筋包围主梁且与主梁具有一定的间隙以增大主梁截面；S4、绑扎腰筋；S5、绑扎主筋；S6、上部负弯矩主筋同步施工：将梁顶新增的负弯矩钢筋植筋在两端的柱子上且靠近楼板位置处，将新增的倒U型箍筋以扣筋的形式植入楼板中，上部增加的负弯矩钢筋可单独进行浇筑，通过上述步骤实现既有结构梁的截面增大。
