Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a highway bridge reinforcement device. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern high-speed development of the transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make the passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings and accessory structures. The upper structure is also called the bridge span structure and is the main structure for crossing obstacles. The lower structure includes abutments, piers and foundations. The bearing is a force transmission device set at the supporting place of the bridge span structure and the pier or abutment. The accessory structures refer to approach slabs, slope protection, diversion projects, etc.

[0003] Chinese Patent Publication No. CN210013139U discloses a highway bridge bearing reinforcement device. Its structure is scientific and reasonable, and it is safe and convenient to use. Since there are support rods, it is convenient to radially fix the pile foundation. Since there is a top plate and a limiting groove is arranged inside the top plate, it is convenient for the limiting groove to be engaged with the top block, which is convenient for installation. Since there are a bottom plate, vertical rods and top rods, it is convenient to axially fix the pile foundation to prevent the fixing plate from sliding down. Since there are a handle, a rotating rod, a rotating shaft, a limiting block and a limiting pin, it is convenient to adjust the pressing force between the top plate and the fixing plate by rotating the handle and make the support rod in a tension state, which increases the overall firmness of the pile foundation reinforcement device. Since this device does not groove or drill holes in the pile foundation, it avoids damaging the integrity of the pile foundation and improves the service life of the pile foundation.

[0029] Specifically, the half support plate 1 is attached to the ground on one side of the bridge support, and the plug rods 13 are inserted into the soil, which can enhance the grip and provide stable support ability;

[0030] Preferably, one half support plate 1 is placed on each side of the bridge support, and the semi-circular plates 14 at the adjacent ends of the two half support plates 1 are fixed with screws, which can support the bottom of the bridge support.

[0031] Specifically, one half collar 2 is placed on each side of the bridge support, and the two half collars 2 are fixed with screws, which can support the middle or upper part of the bridge support.

[0032] Furthermore, a first diagonal brace 3 is connected between the half support plate 1 and the half collar 2, a second diagonal brace 4 is hinged on the first diagonal brace 3, the bottom end of the first diagonal brace 3 is hinged with a translation plate 31, a long bolt 32 is embedded in the middle of the translation plate 31, a guide chute 11 which is slidably connected with the translation plate 31 in a protective manner is opened on the upper side of the half support plate 1, a plurality of threaded holes 12 are equidistantly opened on the guide chute 11, and the long bolt 32 is threadedly connected with one of the threaded holes 12;

[0033] Specifically, the translation plate 31 is pushed to slide linearly along the guiding chute 11 until the first diagonal strut 3 pushes the half collar 2 to reach the required supporting height range. Then, the half collar 2 fits against the bridge bearing, and the long bolt 32 is screwed into the corresponding threaded hole 12 to limit the height of the half collar 2.

[0034] Further, a connecting support plate 5 is hinged to the top end of the second diagonal strut 4. Assembly holes 51 are provided at the four corners of the connecting support plate 5, and expansion bolts 52 are embedded in the assembly holes 51.

[0035] Specifically, after the connecting support plate 5 fits against the bridge flank, a drilling hole is made at the position opposite to the assembly hole 51, and then the expansion bolt 52 is embedded in the drilling hole, which can connect the connecting support plate 5 and the bridge into an integral structure, improving the integrity of the structure.

[0036] Further, an adjusting assembly 6 is connected between the first diagonal strut 3 and the second diagonal strut 4. The adjusting assembly 6 includes an upper connecting pin 61 embedded in the second diagonal strut 4 and a lower connecting pin 62 rotatably embedded in the first diagonal strut 3. One end of each of the upper connecting pin 61 and the lower connecting pin 62 is fixedly connected with a threaded sleeve 63.

Then, the semi-ring 2 is attached to the bridge bearing, and the long bolt 32 is screwed into the corresponding threaded hole 12 to limit the height of the semi-ring 2. Rotate the operating handle 65, and the operating handle 65 drives the double-headed lead screw 64 to rotate. The double-headed lead screw 64 threadedly drives the two threaded sleeves 63 to move away from each other. The upper connecting pin 61 slides along the limiting groove 41, which can push the second diagonal strut 4 to change the inclination angle, so that the connecting support plate 5 can be attached to the bridge flank. After drilling holes at the corresponding positions of the assembly holes 51, embed the expansion bolts 52 into the drilled holes, and the connecting support plate 5 can be connected to the bridge as an integral structure, improving the integrity of the structure. Similarly, arrange the reinforcement device on the other side of the bridge bearing, and screw-fix the semi-supporting plates 1 and semi-rings 2 of the two groups of reinforcement devices to effectively improve the stability of the bridge bearing and the maximum load of the two wings of the bridge. When vehicles pass on the upper side of the bridge, part of the stress is conducted along the second diagonal strut 4 to the first diagonal strut 3, and the first diagonal strut 3 conducts the stress to the semi-supporting plate 1 and the bridge bearing. The stress is converted into horizontal and vertical forces, and the stress is dispersed and offset, effectively improving the stability of the bridge.
