Embodiment 1

[0039] A system for reinforcing corroded steel bars for bridge reinforcement, including a U-shaped plate 4, the left and right sides of the inner wall of the U-shaped plate 4 are equipped with expansion bolts 5 in gaps, and holes are drilled inside the external bridge, and the bridge and the bridge can be connected through the expansion bolts 5 The U-shaped plate 4 is fixed at the valley, and the left and right sides of the inner wall of the U-shaped plate 4 are all provided with a square plate 6, and the square plate 6 plays a position-limiting effect on a plurality of U-shaped plates 4. The bottom of the inner wall of 4 fits together, and the square plate 6 is fixed together with the U-shaped plate 4 through the fixing device 1. The fixing device 1 includes a base 101, a short rod 102, a vertical groove 103, a pole 104, a slot 105, and a latch 106 , rubber columns 107 and transverse grooves 108, the left and right sides of the bottom of the base 101 are respectively attached ...

Embodiment 2

[0041] As an option, see figure 1 , 2, 4, 5 and 6, the corroded steel reinforcement system for bridge reinforcement, the bottom of the pole 104 is provided with a closing device 2, the closing device 2 includes a bottom plate 201, a groove 202 and a ring 203, the outer wall of the bottom plate 201 and the U-shaped plate 4 Welded together, the top of the bottom plate 201 is processed with a groove 202, the groove 202 is used to prevent the ring 203, the ring 203 gives the upward force to the pole 104 through its own deformation, and then makes the bottom of the inner wall of the card groove 105 and the latch 106 The bottom of the bottom of the groove 202 is tightly pressed, and the inner wall of the groove 202 is provided with a ring 203. The top and bottom of the ring 203 are respectively pressed against the bottom of the pole 104 and the bottom of the inner wall of the groove 202. The bottom of the bottom plate 201 is connected to the U-shaped plate 4 The bottom of the botto...

Embodiment 3

[0044] As an option, see figure 1 , and 3, the corroded steel reinforcement system for bridge reinforcement, the outer wall of the square plate 6 is provided with a clamping device 3, and the clamping device 3 includes a horizontal plate 301, a U-shaped bar 302, a nut 303 and a square groove 304, and the top of the horizontal plate 301 A U-shaped bar 302 is provided, and the two ends of the U-shaped bar 302 run through the left and right sides of the horizontal plate 301 respectively. The U-shaped bar 302 cooperates with the horizontal plate 301 to prevent the two square plates 6 from moving away from each other. Nuts 303 are threaded on the left and right sides, and the nuts 303 play a limiting role on the horizontal plate 301 and the U-shaped bar 302. The top of the nut 303 fits the bottom of the horizontal plate 301. bottom, the depth of the square groove 304 is 1 / 2 of the height of the horizontal plate 301, and the width of the square groove 304 is the same as the width of...

Abstract

The invention discloses a system for reinforcing corroded steel bars for bridge reinforcement, which comprises a U-shaped plate, the left and right sides of the inner wall of the U-shaped plate are equipped with expansion bolts in gaps, and the left and right sides of the inner wall of the U-shaped plate are equipped with square bolts. plate. The concrete beneficial effect of the corroded steel bar reinforcement system for bridge reinforcement is as follows, so that multiple U-shaped plates are well fixed with the square plate, and the square plate supports the multiple U-shaped plates stably, thereby ensuring that the bridge reinforcement is rusted. The self-strength of the steel reinforcement system provides a more stable support for the external bridge to ensure the operation effect. The bridge reinforcement uses less bolts and nuts as a whole in the rusted steel reinforcement system, so it takes less time during the installation process. The operation efficiency is improved, the workload of the operators is reduced, and it is more suitable for mass installation. Therefore, the corroded steel bar reinforcement system for bridge reinforcement can better meet people's use needs.

Description

technical field [0001] The invention relates to the technical field of corroded steel bar reinforcement for bridge reinforcement, in particular to a corroded steel bar reinforcement system for bridge reinforcement. Background technique [0002] Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by reinforcing components and improving structural performance, so as to prolong their service life and meet the requirements of modern transportation. Because the bridge is in the harsh environment for a long time, the structure of the reinforced concrete of the bridge will peel off and crack, which will not only affect the overall appearance of the bridge, but also cause corrosion of the steel bars and affect the service life of the bridge. Spraying mortar, but the mortar will still fall off after a long time of use, so it is necessary to use a special reinforcement technology for bridge reinforcement with corroded steel bars. ...
