Description
Technical Field
[0001] This utility model relates to the field of reinforcement devices, and in particular to a bridge hinge joint reinforcement device. Background Technology
[0002] Bridge hinge joints, in bridge engineering, refer to the joints between precast slab beams. They are mainly used to connect two slab beams. The main purpose of hinge joints is to strengthen the overall integrity of the bridge structure and ensure that the bridge can remain stable under its own weight and external loads. Existing bridge hinge joint reinforcement usually involves installing connecting structures between the hinge joints for reinforcement.
[0003] Traditional reinforcement devices typically involve installing a connecting structure between the hinge joints of two slab beams to reinforce the hinge joint. However, since bridges bear the load of vehicles and pedestrians over a long period of time, the slab beams may partially sink, which can easily expose the traditional reinforcement devices to the road surface, thereby damaging vehicle tires and causing safety accidents.
[0004] Therefore, in view of the above-mentioned traditional reinforcement devices, after the slab beams sink, they are prone to damage to the vehicle tires. A bridge hinge joint reinforcement device can be designed, which can solve the above problem by installing the reinforcement device on both sides of the connection between the two sets of beams. Utility Model Content
[0005] To overcome the problem of traditional reinforcement devices, which typically involve installing a connecting structure between the hinge joints to reinforce the hinge joints of the two slab beams, the bridge is subjected to the loads of vehicles and pedestrians for a long time. As the bridge may be subjected to the loads of vehicles and pedestrians for a long time, the slab beams may partially sink, which may cause the traditional reinforcement devices to be exposed to the road surface, thereby damaging the tires of vehicles and causing safety accidents.
[0006] The technical solution of this utility model is: a bridge hinge joint reinforcement device, including a first reinforcement mechanism, a second reinforcement mechanism, a locking shaft and a locking sleeve; a second reinforcement mechanism corresponding to the first reinforcement mechanism is matched on one side of the first reinforcement mechanism, the first reinforcement mechanism includes a first reinforcement plate, and two sets of locking shafts are symmetrically arranged on the side wall of the first reinforcement plate near the second reinforcement mechanism, the second reinforcement mechanism includes a second reinforcement plate, and two sets of locking sleeves corresponding to the locking shafts are symmetrically arranged on the side of the second reinforcement plate near the first reinforcement mechanism.
[0007] Preferably, this application combines a first reinforcing mechanism, a second reinforcing mechanism, a locking shaft, and a locking sleeve, so that during operation, the worker can first loosen the locking sleeve along the locking shaft to adjust the first and second reinforcing mechanisms to a suitable distance between the two sets of beams and plates. Then, the first and second reinforcing mechanisms are installed on both sides of the connection between the two sets of beams and plates. By tightening the locking sleeve, the distance between the first and second reinforcing mechanisms is reduced, thereby completing the installation.
[0008] Preferably, the first reinforcing plate has a first stress-bearing block on the side wall away from the second reinforcing plate, and the second reinforcing plate has a second stress-bearing block corresponding to the first stress-bearing block on the side away from the first reinforcing plate. The surface of the first reinforcing plate is evenly provided with four sets of first mounting holes, and the surface of the second reinforcing plate is evenly provided with four sets of second mounting holes.
[0009] Preferably, the outer end of the locking shaft is fitted with a threaded sleeve, and a limit block is installed at the end of the locking shaft away from the first reinforcing plate.
[0010] Preferably, the outer end of the lock sleeve is provided with a second fixing block, the lock sleeve is located at the center of the first fixing block, the center of the lock sleeve is provided with a lock hole, and the inner wall of the lock hole is provided with a locking thread groove corresponding to the threaded sleeve.
[0011] Preferably, the second reinforcing plate is symmetrically provided with two sets of rotating sleeves on the side of the first reinforcing plate. The end of each set of rotating sleeves away from the second reinforcing plate is provided with a first fixing block. Both ends of the first fixing block are provided with auxiliary locking rods. One end of the auxiliary locking rod is connected to the first reinforcing block, and the other end of the auxiliary locking rod is connected to the second reinforcing block.
[0012] Preferably, the first reinforcement mechanism and the second reinforcement mechanism are matched with a first beam plate and a second beam plate, and a hinge joint connection mechanism is provided between the first beam plate and the second beam plate. Reinforcement grooves are provided on both sides of the first beam plate and the second beam plate. The first reinforcement mechanism and the second reinforcement mechanism are respectively located inside the two sets of reinforcement grooves.
[0013] Preferably, each of the two sets of fixing slots has four sets of pre-embedded holes symmetrically arranged inside. The pre-embedded holes are provided with positioning sleeves, and the positioning sleeves are provided with positioning holes corresponding to the first mounting hole and the second mounting hole. The inner wall of the positioning holes is provided with mounting thread grooves.
[0014] The beneficial effects of this utility model are as follows: Compared with traditional reinforcement devices, which are prone to damaging vehicle tires after the beam sinks, this application uses a first and second reinforcement mechanism designed to be embedded in the reinforcement groove of the beam, avoiding the risk of the reinforcement device being exposed on the road surface due to the sinking of the beam, and reducing potential damage to vehicle tires. The design of the pre-embedded hole and positioning sleeve ensures a tight connection between the reinforcement device and the beam, improving the stability and safety of the overall structure. The design of the locking shaft and locking sleeve allows users to easily adjust and install the reinforcement device without complicated tools or skills. The cooperation of the locking shaft, locking sleeve and auxiliary locking rod ensures a tight connection between the components, reducing the risk of loosening. The design of the first and second force-bearing blocks allows stress to be evenly distributed on the reinforcement plate, avoiding damage caused by local stress concentration. The threaded sleeve and limiting block design at the outer end of the locking shaft prevents loosening problems that may occur during the locking process, increasing the safety of the overall structure.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-4 This utility model provides an embodiment of a bridge hinge joint reinforcement device, including a first reinforcement mechanism 1, a second reinforcement mechanism 2, a locking shaft 3, and a locking sleeve 15; a second reinforcement mechanism 2 corresponding to the first reinforcement mechanism 1 is matched on one side of the first reinforcement mechanism 1, the first reinforcement mechanism 1 includes a first reinforcement plate 101, and two sets of locking shafts 3 are symmetrically arranged on the side wall of the first reinforcement plate 101 near the second reinforcement mechanism 2, the second reinforcement mechanism 2 includes a second reinforcement plate 201, and two sets of locking sleeves 15 corresponding to the locking shafts 3 are symmetrically arranged on the side of the second reinforcement plate 201 near the first reinforcement mechanism 1.
[0022] Please see Figures 1-2In this embodiment, a first force-bearing block 9 is provided on the side wall of the first reinforcing plate 101 away from the second reinforcing plate 201, and a second force-bearing block 11 corresponding to the first force-bearing block 9 is provided on the side of the second reinforcing plate 201 away from the first reinforcing plate 101. Four sets of first mounting holes 8 are evenly opened on the surface of the first reinforcing plate 101, and four sets of second mounting holes 10 are evenly opened on the surface of the second reinforcing plate 201. By combining the first force-bearing block 9 and the second force-bearing block 11, the first force-bearing block 9 and the second force-bearing block 11 can disperse the stress generated by vehicles passing over the bridge when the reinforcing device is used to reinforce the bridge hinge joint. By combining the first mounting hole 8 and the second mounting hole 10, the workers can screw the bolts into the positioning hole 501 of the positioning sleeve 5 through the first mounting hole 8 or the second mounting hole 10 during installation, and install them by matching the bolt threads with the mounting thread groove 502 on the inner wall of the positioning hole 501.
[0023] Please see Figures 2-3 In this embodiment, a threaded sleeve 6 is fitted onto the outer end of the locking shaft 3, and a limiting block 7 is installed at the end of the locking shaft 3 away from the first reinforcing plate 101. A second fixing block 14 is provided at the outer end of the locking sleeve 15, and the locking sleeve 15 is located at the center of the first fixing block 13. A locking hole 16 is opened at the center of the locking sleeve 15, and a locking thread groove 17 corresponding to the threaded sleeve 6 is opened on the inner wall of the locking hole 16. Two sets of rotating sleeves 12 are symmetrically provided on the side of the second reinforcing plate 201 close to the first reinforcing plate 101. A first fixing block 13 is provided at the end of each set of rotating sleeves 12 away from the second reinforcing plate 201. Both ends of the first fixing block 13 are provided with... The auxiliary locking rod 4 is connected at one end to the first reinforcing block and at the other end to the second reinforcing block. It is combined with the locking shaft 3, the rotating sleeve 12 and the locking sleeve 15 so that after the first reinforcing plate 101 and the second reinforcing plate 201 are installed in the reinforcing groove 21, the operator can rotate the auxiliary locking rod 4. The auxiliary locking rod 4 rotates through the rotating sleeve 12 at one end, which drives the locking sleeve 15 at the other end to rotate along the threaded sleeve 6 of the locking shaft 3 through the locking thread groove 17 on the inner wall of the lock hole 16. This reduces the distance between the first reinforcing mechanism 1 and the second reinforcing mechanism 2, thus completing the reinforcement and locking.
[0024] Please see Figures 3-4In this embodiment, the first reinforcing mechanism 1 and the second reinforcing mechanism 2 are matched with a first beam plate 18 and a second beam plate 19. A hinge connection mechanism 20 is provided between the first beam plate 18 and the second beam plate 19. Reinforcing grooves 21 are provided on both sides of the first beam plate 18 and the second beam plate 19. The first reinforcing mechanism 1 and the second reinforcing mechanism 2 are respectively located inside the two sets of reinforcing grooves 21. Four sets of pre-embedded holes are symmetrically provided inside the two sets of fixing grooves. Positioning sleeves 5 are provided inside the pre-embedded holes. Positioning holes 501 corresponding to the first mounting hole 8 and the second mounting hole 10 are provided inside the positioning sleeves 5. The inner wall of the positioning hole 501 is provided with a threaded groove 502. By combining the reinforcing grooves 21 and the positioning sleeves 5, the workers can pre-embed eight sets of positioning sleeves 5 in the four sets of pre-embedded holes of the two sets of fixing grooves during installation. After the concrete solidifies, the positioning sleeves 5 can be firmly installed in the pre-embedded holes, thereby providing positioning for the first reinforcing mechanism 1 and the second reinforcing mechanism 2.
[0025] During operation, the staff can pre-embed eight sets of positioning sleeves 5 into four sets of pre-embedded holes in two sets of fixing grooves. After the concrete solidifies, the positioning sleeves 5 can be firmly installed in the pre-embedded holes, thereby providing positioning for the first reinforcement mechanism 1 and the second reinforcement mechanism 2.
[0026] During installation, workers can screw bolts into the positioning hole 501 of the positioning sleeve 5 through the first mounting hole 8 or the second mounting hole 10, and install them by matching the bolt threads with the mounting thread groove 502 on the inner wall of the positioning hole 501.
[0027] After the first reinforcing plate 101 and the second reinforcing plate 201 are installed in the reinforcing groove 21, the operator can rotate the auxiliary locking rod 4. The auxiliary locking rod 4 rotates through the rotating sleeve 12 at one end, causing the locking sleeve 15 at the other end to rotate along the threaded sleeve 6 of the locking shaft 3 through the locking thread groove 17 on the inner wall of the locking hole 16, thereby reducing the distance between the first reinforcing mechanism 1 and the second reinforcing mechanism 2 and completing the reinforcement and locking.
[0028] Through the above steps, this application combines the first reinforcement mechanism 1, the second reinforcement mechanism 2, the locking shaft 3, and the locking sleeve 15. During operation, the worker can first loosen the locking sleeve 15 along the locking shaft 3 to adjust the first reinforcement mechanism 1 and the second reinforcement mechanism 2 to a suitable distance between the two sets of beams. Then, the first reinforcement mechanism 1 and the second reinforcement mechanism 2 are installed on both sides of the connection between the two sets of beams. By tightening the locking sleeve 15, the distance between the first reinforcement mechanism 1 and the second reinforcement mechanism 2 is reduced, thus completing the installation. This avoids the risk of the reinforcement device being exposed on the road surface due to the sinking of the beams, reduces potential damage to vehicle tires, and ensures a tight connection between the reinforcement device and the beams through the design of the pre-embedded holes and positioning sleeves 5, improving the stability and safety of the overall structure.
