Description

Technical Field

[0001] The present invention relates to the technical field of bridge steel structure reinforcement, in particular to a bridge steel structure reinforcement device. Background Art

[0002] Steel structure bridges are bridges that use steel as the primary load-bearing material and are widely used in highways, railways, and urban transportation. Their main components, such as beams, trusses, and arches, are made of steel plates or steel sections. They have the characteristics of high strength, light weight, and good ductility. Steel structure bridges are fast to construct and can be prefabricated and assembled, making them suitable for large-span designs such as suspension bridges and cable-stayed bridges. The uniformity and plasticity of steel give them excellent seismic performance. T-shaped steel pipes of different specifications are used in steel structure bridges to provide support for the steel structure bridges. However, the angles of these T-shaped steel pipes are stress concentration areas. The angles of the T-shaped steel pipes are squeezed, which can easily cause local deformation or instability, affecting the stability of the steel structure bridge. For this reason, we have proposed a bridge steel structure reinforcement device. Summary of the Invention

The mutual insertion of the rectangular block 1 and the rectangular block 2 can quickly install the two reinforcement components on the front and back sides to the outside of the T-shaped steel pipe, thereby providing reinforcement for the T-shaped steel pipe.

[0008] Furthermore, the mounting assembly includes two C-shaped protrusions, the two C-shaped protrusions are respectively mounted on the outside of the two rectangular blocks, the two C-shaped protrusions are vertically mirrored with the T-shaped steel pipe as the center, a square groove is opened at the center of the front of the two C-shaped protrusions, a slide is slidably connected inside the square groove, a sliding rod is installed on the front of the slide, the back of the sliding rod passes through the C-shaped protrusion and extends into the rectangular block two, the front of the sliding rod passes through the C-shaped protrusion and extends outward, a pull rod is provided on the front of the two slide rods, the front of the two slide rods are both mounted on the back of the pull rod, the outer surface of the slide rod is sleeved with a spring, the back of the spring is mounted on the front of the slide, and the front of the spring is mounted on the inner surface of the front of the square groove; By setting a spring, the spring will rebound after the squeezed state ends, and the rebound of the spring can drive the slide plate and the slide bar to return to their original positions; The sliding rod is slidably connected to the C-shaped protrusion at the penetration point, and the sliding plate is provided to prevent the sliding rod from deflecting during movement, thereby preventing the sliding rod from being accurately inserted into the second rectangular block.

[0012] (2) The present invention sets a mounting portion, specifically, by pulling the pull rod toward the front, so that the pull rod drives the slide rod to move toward the front, and the slide rod drives the slide plate to move toward the front, thereby squeezing the spring. In this way, after the pull rod is released, the slide rod can be quickly inserted into the second rectangular block by the rebound of the spring, thereby completing the installation between the trapezoidal plates on the front and back sides, and facilitating the rapid deployment of the reinforcement portion on the outside of the T-shaped steel pipe that needs to be reinforced, thereby providing support and protection for the angle of the T-shaped steel pipe.

[0013] (3) The present invention sets a diagonal pull portion, specifically by rotating the rotating block 1, and adjusting the angle of the threaded rod. When the rotating block 1 is adjusted to a suitable position, the rotation of the rotating block 1 is stopped, and the screw housing is rotated to move the screw housing downward and adjust it to a length suitable for installing the fixed block 2. Then, the fixed block 2 is fixed to the structure at the bottom of the T-shaped steel pipe. In this way, the concentrated stress at the angle of the T-shaped steel pipe can be transferred to the bottom, reducing local stress concentration and reducing the risk of deformation or damage of the T-shaped steel pipe.

The inclined portion 4 includes an inclined component 41, which is installed at the bottom of the reinforcement component 21.

[0022] The positioning assembly 31 includes two rectangular blocks 1 311 and two rectangular blocks 2 312. The two rectangular blocks 1 311 are respectively mounted on the top and bottom of the trapezoidal plate 211 located on the rear side, and the two rectangular blocks 2 312 are respectively mounted on the top and bottom of the trapezoidal plate 211 located on the front side.

The mutual insertion of the rectangular block 1 311 and the rectangular block 2 312 can quickly install the two reinforcement components 21 on the front and back sides to the outside of the T-shaped steel pipe 1, thereby reinforcing the T-shaped steel pipe 1.

[0023] The mounting assembly 32 includes two C-shaped protrusions 321, which are respectively mounted on the outer sides of the two rectangular blocks 1 311. The two C-shaped protrusions 321 are vertically mirrored with the T-shaped steel pipe 1 as the center. A square groove 322 is provided at the center of the front of the two C-shaped protrusions 321. A slide plate 323 is slidably connected inside the square groove 322. A slide bar 324 is mounted on the front of the slide plate 323.

The back face of the spring 326 is mounted on the front face of the slide plate 323, and the front face of the spring 326 is mounted on the inner surface of the front face of the square groove 322. Pull the pull rod 325 toward the front, so that the pull rod 325 drives the slide bar 324 to move toward the front, and the slide bar 323 is driven toward the front by the slide bar 324, thereby squeezing the spring 326. In this way, after the pull rod 325 is released, the slide bar 324 can be quickly inserted into the second rectangular block 312 by the rebound of the spring 326, completing the installation between the trapezoidal plate 211 on the front and back sides, making it easy to quickly deploy the reinforcement part 2 on the outside of the T-shaped steel pipe 1 that needs to be reinforced, providing support and protection for the angle of the T-shaped steel pipe 1. The sliding rod 324 is slidably connected to the C-shaped protrusion 321 at the penetration point, and the sliding plate 323 is provided to prevent the sliding rod 324 from deflecting during movement, which may cause the sliding rod 324 to be unable to be accurately inserted into the rectangular block 2 312 .

When the rotating block 1 412 is adjusted to a suitable position, stop the rotation of the rotating block 1 412 and rotate the screw housing 415 to move the screw housing 415 downward and adjust it to a length suitable for installing the fixing block 2 417. Then, fix the fixing block 2 417 to the structure at the bottom of the T-shaped steel pipe 1. In this way, the concentrated stress at the angle of the T-shaped steel pipe 1 can be transferred to the bottom, reducing local stress concentration and reducing the risk of deformation or damage of the T-shaped steel pipe 1. A limiting protrusion 414 is installed at the bottom center of the threaded rod 413 to limit the range of movement of the screw housing 415 and prevent the screw housing 415 from accidentally sliding off the outside of the threaded rod 413.

The top of the auxiliary pull rod 422 away from the C-shaped protrusion 321 is rotatably connected to the positioning block 423. Among them, the positioning block 2 423 is used to be installed on an object near the T-shaped steel pipe 1 to disperse the load on the T-shaped steel pipe 1 and the reinforcement component 21 outward to prevent stress concentration from causing damage to the T-shaped steel pipe 1 and the reinforcement component 21.

[0026] When in use, first take out several reinforcement components 21, and align the special-shaped groove 1 313 and the special-shaped groove 2 314 with the special-shaped block 1 315 and the special-shaped block 2 316 and plug them together, position the rectangular block 1 311 and the rectangular block 2 312 together, so that the trapezoidal plate 211 on the back is connected to the trapezoidal plate 211 on the front, and then release the pull rod 325, so that the slide plate 323 stops compressing the spring 326. The spring 326 that has lost its compression will return to its original position by rebounding, and the slide plate 323 will drive the slide rod 324 to rebound and return to its original position, and the slide rod 324 will be inserted into the C-shaped protrusion 321 to complete the locking between the two trapezoidal plates 211 on the front and back. Next, the trapezoidal plate 211 is placed on the outside of the T-shaped steel pipe 1, and the reinforcement component 21 is fixed to the outside of the T-shaped steel pipe 1 with screws. Then, the knob 222 is turned counterclockwise to rotate the screw rod 213, and the circular protrusion 214 drives the square protrusion 215 to move, so that the square protrusion 215 drives the reinforcement protrusion 216 to move to the angle at the bottom of the T-shaped steel pipe 1 to support and reinforce it. Next, rotate the screw housing 415 to adjust the total length of the screw housing 415 and the threaded rod 413 to a length that is convenient for installation on the bottom structure of the T-shaped steel pipe 1, then rotate the fixing block 1 411 and the fixing block 2 417 to adjust them to a suitable installation angle, and then use screws to install the fixing block 2 417 on the structure at the bottom of the T-shaped steel pipe 1, and then repeat the operation to adjust the positioning block 2 423 to a suitable position and lock it on the structure at the top of the T-shaped steel pipe 1, so that the force applied at the angle is transmitted to the top and bottom structures of the T-shaped steel pipe 1, thereby improving the stiffness of the connection of the T-shaped steel pipe 1 and the stability of the overall bridge, and providing additional support force so that the angle can withstand a larger load, thereby enhancing the bridge's resistance to heavy loads or dynamic loads.
