Fabricated precast concrete foundation reinforcing structure
The invention discloses an assembly type precast concrete foundation reinforcing structure which comprises foundation reinforcing structure split components, and reserved U-shaped steel bar extending ends on the two foundation reinforcing structure split components are fixedly bound with additional hook-shaped opening ribs and vertical ribs. The extending ends of the reserved transverse bars on the two foundation reinforcing structure split components are bound and fixed with the additional column encircling stirrups, the column encircling stirrups are fixed in pairs and hooped on the structural column in an encircling manner, and the two foundation reinforcing structure split components and the structural column are connected into a whole through a concrete post-cast strip; the extending ends of the reserved connecting steel bars on the foundation reinforcing structure split components are in grouting connection with grouting holes formed in an original foundation, and the extending ends of the vertical bars are in grouting connection with grouting holes formed in the original foundation. The method is based on the existing building foundation reinforcement and transformation technology, construction procedures can be reduced, the construction progress can be accelerated, the construction quality can be improved, and the difficulty that existing building foundation reinforcement cast-in-place concrete and large equipment are difficult to enter is overcome.
本发明公开了一种装配式预制混凝土基础加固结构，包括基础加固结构分体构件，两个基础加固结构分体构件上的预留U形钢筋伸出端与附加弯钩形开口筋、竖筋绑扎固定，两个基础加固结构分体构件上的预留横筋伸出端与附加的柱围套箍筋绑扎固定，柱围套箍筋两两固定并围箍在结构柱上，并经混凝土后浇带使两个基础加固结构分体构件与结构柱连接成为一体；基础加固结构分体构件上的预留连接钢筋伸出端与原基础上设置的灌浆孔进行灌浆连接，竖筋伸出端与原基础上设置的灌浆孔进行灌浆连接。本发明是基于既有建筑的基础加固改造技术，能减少施工工序、加快施工进程、提高施工质量，克服既有建筑基础加固现浇混凝土，大型设备难以进入的困难。
