Detailed Description

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a crack reinforcing apparatus for bridge, includes

bridge subject

1, 1 lower extreme of bridge subject rotates installs four screw reinforcing rod 2 that are the rectangle and distribute, 2 peripheries of screw reinforcing rod are equipped with connecting

block

3, 3 internal rotations of connecting block are installed and are rotated the screw ring 16 of being connected with 2 peripheries of screw reinforcing rod, 3 upsides of four connecting blocks are equipped with the gusset plate 4 with 1 lower terminal surface laminating of bridge subject, 4 lower extremes of gusset plate rotate the screw sleeve 6 of installing two symmetries and setting up, connect fixedly through two-way threaded rod 7 between two screw sleeve 6.

Specifically, a threaded hole 9 which is rotatably connected with the threaded reinforcing rod 2 is formed in the lower end face of the bridge main body 1; the installation and the fixation of the thread reinforcing rod 2 are convenient.

Furthermore, a support plate 8 is rotatably arranged between the left and right connecting blocks 3, and the front and rear connecting blocks 3 are fixedly connected through a support rod 15; through spacing to connecting block 3, improve the tensile strength between the screw reinforcing rod 2, and then improve and consolidate bridge main part 1.
