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

[0002] Bridges are indispensable infrastructure projects in transportation and urbanization construction. Bridges connect various bridge sections and piers through node connections. Node connections are often the most prone to wear and tear. When repairing old bridges, they often need to rely on node reinforcement devices to reinforce the bridges. Existing node reinforcement devices mostly add reinforcement plates and use diagonal rods for reinforcement. However, the compressive force on the bridge deck is all dispersed to the piers, causing a large load on the piers, making it difficult to disperse the force upward to improve the reinforcement support effect. When the bridge deck is under too much pressure, it is difficult to buffer and disperse the force in different directions to reduce the load transmitted to the piers. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example: Please refer to Figures 1 to 5 :

[0031] The utility model proposes a bridge node reinforcement device, comprising: a support frame 1; the support frame 1 is fixedly installed between the top of the bridge pier and the bridge surface, and two groups of upper top members 2, two linkage blocks 3, a pressure-bearing member 4, two rotating tubes 5 and two pressure-bearing columns 6 are installed on the top surface of the cross section of the support frame 1; the inner end surface of the upper top member 2 is a slope structure and fits on the outer slope of the linkage block 3; the inner slope of the linkage block 3 fits on the outer slope of the pressure-bearing member 4; two insertion holes 402 are provided inside the pressure-bearing member 4, and the inner part of the insertion holes 402 is clamped with the pressure-bearing column 6; the top surface of the pressure-bearing column 6 is fixedly connected to the bottom surface of the bridge surface.

[0032] In the present disclosure, Figure 4 As shown in the figure, the support frame 1 is integrally in a U-shaped structure. A longitudinal slideway 101 is connected to the inner vertical surface of the support frame 1 by bolts, and a transverse slideway 102 is connected to the top surface of the horizontal section of the support frame 1 by bolts. Moreover, two wedge-shaped bayonets 103 are provided on the top surface of the support frame 1, and the bayonets 103 are directly below the bottom wedge-shaped tips of the pressure-bearing member 4. The support frame 1 can be used to support the bottom of the bridge deck, thereby strengthening the node position between the bridge deck and the bridge pier. When the pressure-bearing member 4 has a downward movement tendency, the bayonets 103 can satisfy a small downward displacement of the pressure-bearing member 4, satisfying slight elastic deformation. In this way, when the bridge deck is suddenly pressed down due to the scattering of goods or the rollover of a truck, etc., resulting in large deformation, the situation where the bridge deck is prone to collapse can be avoided.

[0033] In the embodiment of the present disclosure, as Figure 4 shown in the figure, a transverse chute 301 is provided on the bottom surface of the linkage block 3, and the transverse slideway 102 is clamped inside the transverse chute 301. When the pressure-bearing member 4 moves down a little distance, it pushes the linkage block 3 to move outwards. The linkage block 3 moves outwards on the transverse slideway 102, and at the same time pushes the upper jacking member 2 to move upwards, completing the linkage and realizing the dispersion of force.

[0034] In the embodiment of the present disclosure, as Figure 5 shown in the figure, a rotating bar 601 is welded to the outer wall of the pressure-bearing column 6. A spiral outer groove 602 is provided below the outer wall of the pressure-bearing column 6 and the rotating bar 601, and the outer groove 602 matches the groove shape of the built-in groove 501. The part of the rotating bar 601 protruding from the pressure-bearing column 6 is clamped in the built-in groove 501. A support plate 603 is welded to the outer wall of the pressure-bearing column 6 and the top end of the rotating bar 601. The top surface of the support plate 603 is closely attached to the bottom surface of the pressure-bearing member 4. When the pressure-bearing column 6 is pressed and moves down a little distance, it simultaneously presses the pressure-bearing member 4 to move downwards. The force is dispersed upwards through the linkage block 3. At the same time, when the pressure-bearing column 6 moves downwards, it pushes the rotating tube 5 to rotate by a certain angle through the rotating bar 601, so that part of the force can be dispersed to reduce the downward-transmitted load.

[0035] In the embodiment of the present disclosure, as Figure 4 shown in the figure, a longitudinal chute 201 is provided on the outer end surface of the upper jacking member 2, and the longitudinal slideway 101 is clamped inside the longitudinal chute 201. Moreover, the top surface area of the upper jacking member 2 is larger than the bottom surface area. By using the mutual cooperation of the longitudinal chute 201 and the longitudinal slideway 101, when the upper jacking member 2 is subjected to an outward thrust, it will move upwards, thereby dispersing the force upwards in the reverse direction and reducing the load on the bridge pier.

[0036] In the embodiment of the present disclosure, as Figure 2 and Figure 4As shown, a notch 403 is provided on the outer inclined surface of the pressure-bearing part 4, and a reset sleeve 401 is fixedly connected to the inner vertical surface of the pressure-bearing part 4. The interior of the reset sleeve 401 is connected to a round rod through a high-pressure spring. When the round rod is pushed inward, the high-pressure spring is compressed. When the heavy object on the bridge surface leaves, the high-pressure spring will push the round rod to automatically reset, which plays a certain buffering role and can realize the automatic reset of the rotating tube 5. When the pressure-bearing part 4 moves downward, the notch 403 can be used to allow the pressure-bearing part 4 to move to the horizontal slide 102 without being damaged, thereby meeting the movement requirements of the pressure-bearing part 4.

[0037] In the present disclosure, Figure 5 As shown, a connecting block 502 is welded to the outer wall of the rotating tube 5, and a push rod 5021 is fixedly connected to the inside of the connecting block 502. A built-in groove 501 is opened on the inner wall of the rotating tube 5. The built-in groove 501 is a spiral structure and is filled with a non-Newtonian fluid. The end of the push rod 5021 is aligned with and fits to the round rod of the reset sleeve 401. When the pressure column 6 moves downward, it pushes the rotating tube 5 to rotate at a certain angle. The non-Newtonian fluid inside the built-in groove 501 is pressurized and the resistance becomes greater instantly, thereby improving the effect of reinforcing support. At the same time, the connecting block 502 drives the push rod 5021 to push the round rod of the reset sleeve 401 to retract, thereby dispersing part of the force and converting it into rotational force to reduce the load on the bridge piers.

[0038] The working principle of this embodiment is as follows: first, fill the inner part of the inner groove 501 with non-Newtonian fluid, then snap the turn bar 601 into the inner part of the inner groove 501, and squeeze the non-Newtonian fluid into the inner part of the inner groove 501 and the outer groove 602 at the same time, after the pressure-bearing column 6 passes through the insertion hole 402, the top surface of the pressure-bearing column 6 is fixedly connected to the bottom surface of the bridge deck, the linkage block 3 is snapped onto the transverse slide 102, the upper top piece 2 is snapped onto the longitudinal slide 101, and the support frame 1 is fixedly installed between the top of the bridge pier and the bridge deck;

[0039] The pressure-bearing column 6 moves downward under pressure, and the non-Newtonian fluid inside the built-in groove 501 will instantly increase its resistance under pressure, thereby improving the effect of reinforced support. The rotating tube 5 is pushed to rotate at a certain angle through the turning bar 601 to achieve force dispersion. At the same time, the connecting block 502 drives the push rod 5021 to push the round rod of the reset sleeve 401 to retract, thereby dispersing the force again. When the pressure-bearing part 4 moves down a little distance, it pushes the linkage block 3 to move outward. The linkage block 3 moves outward on the transverse slide 102, and at the same time pushes the upper part 2 to move upward, completing the linkage and achieving force dispersion, thereby reducing the load on the pier.
