Description

Technical Field

[0001] This utility model relates to the field of bridge deck technology, and more specifically, to a road and bridge deck joint reinforcement device. Background Technology

[0002] With the increase in traffic volume, the frequent occurrence of overloading, and the impact of the natural environment, road and bridge deck joints are prone to cracking, displacement, and steel corrosion, which leads to a decrease in structural load-bearing capacity and even threatens traffic safety. Therefore, it is necessary to improve the reliability of the joints through reinforcement devices. Traditional highway and railway bridge deck joint reinforcement devices without anchor protection will experience rusting of the clamps or anchor rings that fix the steel strands after long-term use, which will lead to the failure of the clamp engagement, resulting in prestress loss or even structural safety hazards.

[0003] A search revealed that publication number CN222435103U discloses a road and bridge panel joint reinforcement device, comprising a first panel, with a second panel disposed on one side of the first panel; a connecting component is jointly disposed on one side of the first panel and inside the second panel; a reinforcement component is jointly disposed at the bottom of the first panel and the second panel. Through the combined use of square columns, connecting blocks, irregular blocks, round rods, and frustums, this device can improve the service life of the panels, reduce reliance on bolts alone, provide a more stable and compact structure, thereby enhancing the overall load-bearing capacity and stability, reducing displacement and loosening between panels, reducing the need for maintenance and repair, lowering maintenance costs and cycles, and effectively slowing down road surface aging and wear. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Traditional bridge deck joint reinforcement devices without anchorage protection are prone to rust and corrosion when exposed to humid, salt spray, and acid / alkali environments for a long time. Rust may appear on the surface of the clamps or anchor rings that fix the steel strands, leading to clamp engagement failure or anchor ring breakage due to rust, which may result in loss of prestress or even structural safety hazards. Furthermore, existing bridge deck joint fixing devices without anti-loosening treatment may experience bolt loosening and displacement of the fixing joints during long-term use, thus affecting the overall structure.

[0005] Therefore, a road and bridge panel node reinforcement device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a road and bridge panel node reinforcement device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge panel node reinforcement device, comprising a support component, an anchor mechanism, and a filling layer, wherein the anchor mechanism is installed above the support component, and the filling layer is installed above the anchor mechanism.

[0008] Preferably, the support assembly includes a support pad, a shock-absorbing pad, and an anti-loosening component, and a shock-absorbing pad is disposed above the support pad, and an anti-loosening component is installed above the shock-absorbing pad.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] As attached Figures 1 to 4 The bridge deck joint reinforcement device shown includes a support component 1, an anchor mechanism 2, and a filling layer 3. The anchor mechanism 2 is installed on the top of the support component 1, and the filling layer 3 is installed on the top of the anchor mechanism 2.

[0025] Specifically, when reinforcing cracks on a highway bridge deck, workers first need to fix the support component 1 above the concrete structure, then use bolts to fix the support component 1 and the anchorage mechanism 2, apply tension to the anchorage mechanism 2, and then pour concrete on top of it to form a filling layer 3 above and around the anchorage mechanism 2, thus sealing the node reinforcement device. Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the support assembly 1 includes a support pad 4, a shock-absorbing pad 5, and an anti-loosening component 6. The shock-absorbing pad 5 is disposed above the support pad 4, and the anti-loosening component 6 is installed above the shock-absorbing pad 5. The support pad 4 of the support assembly 1 is placed on the surface of the concrete structure according to the design position to provide support for the anchor mechanism 2. Then, the shock-absorbing pad 5 and the anchor plate 13 are fixed in sequence by the anti-loosening component 6.

[0028] In a preferred embodiment, the anti-loosening component 6 includes a chemical bolt 7, a first anti-loosening washer 8, and a second anti-loosening washer 9. The first anti-loosening washer 8 is provided on the outer diameter surface of the chemical bolt 7, and the second anti-loosening washer 9 is provided below the first anti-loosening washer 8. During the process of fixing the chemical bolt 7, the worker needs to insert the first anti-loosening washer 8 and the second anti-loosening washer 9 into the outer diameter surface of the chemical bolt 7 in sequence, and then tighten the chemical bolt 7 by tightening the tightening device to fix the shock-absorbing plate, the anchor plate 13, and the support pad.

[0029] In a preferred embodiment, the anchor mechanism 2 includes a main body component 10, a fixing component 11, and a protective component 12. The fixing component 11 is installed on the top of the main body component 10, and the protective component 12 is provided on the outer wall of the fixing component 11. When the anchor mechanism 2 needs to be assembled, the top of the main body component 10 is first fixed by the fixing component 11 to prevent the position of the main body component 10 from shifting. Then, the protective component 12 is put on to protect the fixing component 11 as a whole, preventing the fixing component 11 from being damaged due to rust, thereby causing safety hazards to the entire reinforcement device.

[0030] In a preferred embodiment, the main body component 10 includes an anchor plate 13, a guide sleeve 14, and a steel strand assembly 15. The guide sleeve 14 is installed on the side of the anchor plate 13, and the steel strand assembly 15 is installed on the inner diameter surface of the guide sleeve 14. The steel strand assembly 15 and the guide sleeve 14 are interference-fitted, and the anchor plate 13 and the guide sleeve 14 are interference-fitted. When assembling the anchor mechanism 2, the worker needs to guide the steel strand assembly 15 through the guide sleeve 14 of the main body component 10 to pass through the anchor plate 13 hole of the anchor plate 13 and fix the two.

[0031] In a preferred embodiment, the fixing component 11 includes a clamp 16, an anchor ring 17, and an anchor sleeve 18. The anchor ring 17 is installed on the outer diameter surface of the clamp 16, and the anchor sleeve 18 is installed above the anchor ring 17. After the clamp is embedded around the steel strand assembly 15, the worker uses a tool to gently tap it to make the clamp evenly bite the steel strand assembly 15. Then, one side of the steel strand assembly 15 is connected to the tensioning equipment, and the steel strand assembly 15 is tensioned in stages according to the design requirements. After reaching the design stress, it is anchored. Then, the anchor ring 17 is put into the bottom of the clamp, and the anchor sleeve 18 is fixed above the anchor ring 17 with bolts to protect and fix the exposed part of the steel strand assembly 15.

[0032] In a preferred embodiment, the protective component 12 includes a protective cover 19, a sealing ring 20, and a limiting plate 21. The sealing ring 20 is bonded to the lower part of the protective cover 19, and the limiting plate 21 is installed on the upper part of the protective cover 19. After one side of the steel strand assembly 15 is fixed, the worker needs to install the protective cover 19 of the protective component 12 on the outer diameter surface of the fixing component 11. The sealing ring 20 is installed between the anchor plate 13 and the steel strand assembly 15, and between the protective cover 19 and the anchor plate 13 for sealing. Then, the limiting plate 21 is installed on the upper part of the protective cover 19 to control the movement position of the steel strand assembly 15.

[0033] In a preferred embodiment, the steel strand assembly 15 includes a first steel strand 22, a second steel strand 23, and a connecting sleeve 24. The connecting sleeve 24 is installed below the first steel strand 22, and the second steel strand 23 is installed below the connecting sleeve 24. If the steel strands need to be lengthened, workers can connect the first steel strand 22 and the second steel strand 23 through the connecting sleeve 24 to achieve the overall lengthening of the steel strands.

[0034] The working process of this utility model is as follows: First, when it is necessary to construct on the cracked part of the highway bridge, the worker needs to first treat the base surface, drill holes in the concrete structure, and place the support pad 4 of the support component 1 on the surface of the concrete structure according to the design position to provide support for the anchor mechanism 2. Then, the shock-absorbing pad 5 and the anchor plate 13 are fixed in sequence by the chemical bolts 7 of the anti-loosening component 6. During the process of fixing them with the chemical bolts 7, the worker needs to insert the first anti-loosening washer 8 and the second anti-loosening washer 9 in sequence into the outer diameter surface of the chemical bolt 7. Then, the chemical bolt 7 is tightened by the tightening equipment to fix the shock-absorbing plate, the anchor plate 13 and the support pad. The support pad 4 and the shock-absorbing pad 5 are placed on the anchor plate 13 and the anchor plate 13. The concrete not only disperses pressure but also acts as a shock absorber. Then, the worker guides the steel strand assembly 15 through the guide sleeve 14 of the main component 10 and inserts it into the hole of the anchor plate 13, ensuring it is straight and free of tangling. The worker then installs the clamp and anchor ring 17 at the tensioning end of the steel strand assembly 15. After the clamp is embedded around the steel strand assembly 15, the worker uses a tool to gently tap it to make the clamp evenly grip the steel strand assembly 15. The worker then connects one side of the steel strand assembly 15 to the tensioning equipment and tensions the steel strand assembly 15 in stages according to the design requirements. After reaching the design stress, the steel strand assembly 15 is anchored. Then, the anchor ring 17 is fitted into the bottom of the clamp, and the anchor sleeve 18 is fixed above the anchor ring 17 with bolts to protect and fix the exposed part of the steel strand assembly 15.

[0035] If the steel strands need to be extended, workers can connect the first steel strand 22 and the second steel strand 23 through the connecting sleeve 24 to extend the steel strands as a whole. After one side of the steel strand assembly 15 is fixed, workers need to install the protective cover 19 of the protective assembly 12 on the outer diameter surface of the fixed assembly 11. A sealing ring 20 is installed between the anchor plate 13 and the steel strand assembly 15, and between the protective cover 19 and the anchor plate 13 for sealing. Then, a limiting plate 21 is installed above the protective cover 19 to control the movement position of the steel strand assembly 15. Finally, concrete or cement grout is used to seal the anchor mechanism 2 to form a filling layer 3, completing the entire installation process. The above is the working principle of this road and bridge panel node reinforcement device.
