Reinforcing structure for truncation of connecting reinforcing steel bars in sleeves and construction method thereof
The invention discloses a reinforcing structure for truncation of connecting reinforcing steel bars in sleeves. The reinforcing structure is used for repairing sleeve grouting joints between prefabricated shear walls, at reinforcing positions, upper connecting parts of the two pre-bent connecting reinforcing steel bars are in lap joint with and welded to the single faces of the two sides of the outer walls of the lack-of-bar sleeves to form weld joints correspondingly, and lower connecting parts of the two pre-bent connecting reinforcing steel bars are in lap joint with and welded to the single faces of the two sides of the lower connecting reinforcing steel bars to form weld joints correspondingly; shear wall chiseling areas and floor chiseling areas are filled with ultrahigh-performanceconcrete; and the prefabricated shear walls and the adjacent lower layers of prefabricated shear walls are connected into a whole at the lack-of-bar sleeves through the upper connecting reinforcing steel bars, the lack-of-bar sleeves, the pre-bent connecting reinforcing steel bars, the lower connecting reinforcing steel bars, grouts, the weld joints and the ultrahigh-performance concrete. The invention further provides a reinforcing method for guiding construction and meeting the reinforcing requirement. The reinforcing structure is little in damage to the original structure, simple in reinforcing connection mode and controllable in cost.
本发明公开了一种针对套筒内连接钢筋被截断的加固结构，用于修复预制剪力墙之间的套筒灌浆连接节点，在加固位置处，采用两根预弯连接钢筋的上段连接部分别与缺筋套筒的外壁两侧单面搭接焊连接并形成焊缝，两根预弯连接钢筋的下段连接部分别与下段连接钢筋的两侧单面搭接焊连接并形成焊缝；剪力墙剔凿区及楼板剔凿区内填充有超高性能混凝土；预制剪力墙与相邻下层的预制剪力墙在缺筋套筒处通过上段连接钢筋、缺筋套筒、预弯连接钢筋、下段连接钢筋、灌浆料、焊缝和超高性能混凝土形成一个整体；还提供一种加固方法，以指导施工，满足加固需求。本发明对原结构的破坏较小、加固连接方式简单且成本可控。
