Efficient shear-resistant reinforcing method for prestressed hollow slab girder bridge
According to the scheme, the prestressed hollow slab girder bridge comprises a plurality of hollow slabs which are arranged side by side, through holes are formed in the hollow slabs, a plurality of regular triangular plates and inverted triangular plates are arranged in the through holes, and the regular triangular plates and the inverted triangular plates are alternately arranged; a plurality of general reinforcing steel bars are fixedly arranged in the right triangular plates and the inverted triangular plates in a penetrating mode, the third nuts are rotated, the first nuts and the second nuts can pull the third reinforcing steel bars, the first reinforcing steel bars, the second reinforcing steel bars and the fourth reinforcing steel bars, and the stability of the right triangular plates and the inverted triangular plates in the through holes is improved; the hollow slabs are reinforced in the transverse direction, the vertical direction and the longitudinal direction, the spaces in the through holes are filled with the high-performance concrete in the through holes, then the whole hollow slabs can be reinforced, a second bevel gear is rotated to drive a first nut to rotate, every two adjacent hollow slabs are connected and reinforced, and the bearing capacity and shearing resistance of the hollow slabs can be improved.
本发明公开了一种预应力空心板梁桥高效抗剪加固方法，现提出如下方案，其包括多个并排排放的空心板，所述空心板内设有通孔，所述通孔内设有多个正三角板和倒三角板，且正三角板与倒三角板交替排布，多个所述正三角板和倒三角板内均固定贯穿有多个通用钢筋，本发明分别转动第三螺母、第一螺母和第二螺母能够通过牵引第三钢筋、第一钢筋和第二钢筋与第四钢筋，增加正三角板和倒三角板在通孔内的稳固性，从横向竖向以及纵向对空心板进行加固，使通孔内的高性能混凝土将通孔内的空间填实，进而能够对整个空心板进行加固，通过转动第二伞齿轮带动第一螺母转动，在将相邻两个空心板连接加固，还能够增加空心板的承载力与抗剪力。
