[0037] Embodiment one

[0038] As Figures 1-10 As shown in a kind of modularization quick assembly connecting structure for road bridge construction, comprising: quick-mounting component 100 and prefabricated pavement component 200;Quick-mounting component 100 includes: I-shaped connecting seat 300, horizontal positioning piece 400, vertical positioning piece 500 and deceleration ridge mechanism 600;The assembly socket of both sides of I-shaped connecting seat 300 is all inserted with prefabricated pavement component 200, and two assembly sockets are equipped with horizontal positioning piece 400 for being laterally positioned in the horizontal positioning hole of prefabricated pavement component 200;Vertical positioning piece 500 is vertically positioned in the vertical insertion hole of I-shaped connecting seat 300 and the vertical positioning hole of prefabricated pavement component 200;I-shaped connecting seat 300 top is provided with deceleration ridge mechanism 600.Vertical positioning hole is located on the protruding part of prefabricated pavement component 200 inserted into assembly socket.

[0039] The utility model discloses a modularization quick assembly connecting structure for road and bridge construction, which is composed of a quick assembly component 100 and a prefabricated pavement component 200. Two adjacent prefabricated pavement components 200 can be quickly assembled and connected through one quick assembly component 100. During construction, the quick assembly connecting structure can realize the quick assembly construction of pavement structures such as roads and bridges, greatly reducing the construction difficulty and labor intensity, making the connection process more efficient, and significantly shortening the construction period. The modularization quick assembly connecting structure realizes efficient construction through integrated design and standardized prefabricated components. During construction, the I-shaped connecting seat 300 is the basic support of the entire structure, providing a mounting platform for other components. The I-shaped connecting seat 300 is also cooperated with the longitudinal positioning piece 500 to play the role of longitudinal positioning and connecting the prefabricated pavement component 200. The special I-shaped structure can disperse and withstand the pressure from above and the side, improving the stability of the structure. The I-shaped connecting seat 300 is provided with an assembly socket on both sides, and the prefabricated pavement component 200 can be inserted into the socket. The transverse positioning piece 400 is transversely arranged in the transverse positioning hole of the prefabricated pavement component 200, limiting the longitudinal movement of the prefabricated pavement component 200, making the connection between the two adjacent prefabricated pavement components 200 tight and accurate, and enhancing the stability of the structure in the transverse direction. The longitudinal positioning piece 500 is longitudinally arranged in the longitudinal socket of the I-shaped connecting seat 300 and the longitudinal positioning hole of the prefabricated pavement component 200, thereby connecting the I-shaped connecting seat 300 and the prefabricated pavement component 200 together in the longitudinal direction, preventing the prefabricated pavement component 200 from moving horizontally in the longitudinal direction, and ensuring the integrity and stability of the structure. The speed bump mechanism 600 is arranged above the I-shaped connecting seat 300, which plays the role of speed reduction on the road and bridge, reminding the vehicle driver to pay attention to safety. At the same time, as an additional connecting and fixing component, the speed bump mechanism 600 can further enhance the stability of the entire structure. Since the utility model adopts modularization design, each component can be produced in a standardized manner in a factory and then transported to the construction site for quick assembly. Compared with the traditional on-site construction method, this quick assembly method greatly shortens the construction period, reduces the time and labor cost of on-site construction, and only needs simple plug-in and installation operations, without complex construction technology and professional skills, reducing the construction difficulty and requirements for construction personnel. Through the double positioning action of the transverse positioning piece 400 and the longitudinal positioning piece 500 and the support of the I-shaped connecting seat 300, the connection between the prefabricated pavement components 200 is more tight and stable, can withstand greater load and external force, and improves the overall stability and safety of the road and bridge structure.

[0040] Example two

[0041] As Figures 1-10As shown, the longitudinal positioning member 500 comprises: an anchoring pipe 501, the anchoring pipe 501 is arranged in the longitudinal insertion hole and the longitudinal positioning hole in the middle part, the limiting ring 502 at the top of the anchoring pipe 501 is clamped in the clamping groove on the upper surface of the I-shaped connecting base 300, the diameter of the clamping groove is greater than the diameter of the longitudinal insertion hole communicated with the clamping groove, and the side wall of the anchoring pipe 501 is provided with a plurality of grouting holes 503. In order to improve the stability after construction of the utility model, the anchoring pipe 501 can pass through the longitudinal insertion hole and the longitudinal positioning hole, and the bottom of the anchoring pipe 501 can be anchored in the foundation. When anchoring, the anchoring pipe 501 is provided with a plurality of grouting holes 503 on the side wall, grout can be injected into the anchoring pipe 501, and the grout can be injected into the foundation through the plurality of grouting holes 503. After the grout is dried, the anchoring pipe 501 is clamped in the clamping groove on the upper surface of the I-shaped connecting base 300, the diameter of the clamping groove is greater than the diameter of the longitudinal insertion hole communicated with the clamping groove, so that the height position of the I-shaped connecting base 300 is limited, and the stability after anchoring is improved.

[0042] The horizontal positioning member 400 comprises: a horizontal positioning rod 401, a horizontal seat 402 and a bolt 403; the horizontal seat 402 is connected in the embedding groove on the side of the I-shaped connecting base 300 by a plurality of bolts 403, and the embedding groove is located on the inner side of the assembly insertion port; a plurality of horizontal positioning rods 401 for being inserted into the horizontal positioning hole of the prefabricated pavement component 200 are fixed on the horizontal seat 402. The horizontal seat 402 in the horizontal positioning member 400 is detachably connected with the I-shaped connecting base 300, so that the horizontal positioning member 400 can be replaced when the horizontal positioning rod 401 is bent or damaged to affect the positioning effect. The plurality of horizontal positioning rods 401 of the horizontal positioning member 400 are used for being inserted into the horizontal positioning hole of the prefabricated pavement component 200, and play a guiding and limiting role. The horizontal positioning rod 401 is arranged perpendicularly to the anchoring pipe 501, so that the I-shaped connecting base 300 and the prefabricated pavement component 200 are stably connected.

[0043] Embodiment three

[0044] As shown in the figure, Figures 1-10 The speed reduction ridge mechanism 600 comprises: a trapezoidal ridge body 601, the trapezoidal ridge body 601 is fixed on the top of the T-shaped sliding seat 602, the T-shaped sliding seat 602 is sealingly and slidingly matched in the T-shaped groove on the upper surface of the I-shaped connecting base 300, and the bottom of the T-shaped sliding seat 602 is connected with the bottom surface of the T-shaped groove through a plurality of compression springs 603. The top surface and the two inclined side surfaces of the trapezoidal ridge body 601 are provided with strip grooves, and elastic rubber pads 604 are fixedly connected in the three strip grooves.

[0045] The deceleration ridge mechanism 600 in this invention serves as a warning, prompting vehicles to slow down. However, the bottom of the T-shaped slide 602 is connected to the bottom of the T-shaped groove via multiple compression springs 603. When a vehicle drives over the trapezoidal ridge 601, the trapezoidal ridge 601 slides downwards within the T-shaped groove along with the T-shaped slide 602, compressing the springs. The compression springs 603 act as a buffer and shock absorber, effectively reducing the impact force generated when a vehicle passes over the deceleration ridge. This not only reduces damage to the vehicle itself but also reduces the impact on the road and bridge structure, extending the service life of the road and bridge. Furthermore, in The top surface and the two inclined sides of the trapezoidal ridge 601 are provided with elastic rubber pads 604, and the thickness of the pads is greater than the depth of the groove. When a vehicle comes into contact with the speed ridge, the elastic rubber pads 604 are first squeezed and deformed, further absorbing and dispersing the impact force of the vehicle, playing a secondary buffering role, making the vehicle pass through the speed ridge more smoothly and comfortably, and reducing damage to the speed ridge mechanism 600. The T-shaped slide block 602 is sealed and slides in the T-shaped groove on the upper surface of the I-shaped connecting seat 300, which can prevent dust, rainwater and other impurities from entering the T-shaped groove and ensure the smooth sliding of the T-shaped slide block 602. Furthermore, the sealed fit enhances structural stability, preventing the speed bump mechanism 600 from loosening or shifting during long-term use, ensuring the speed bump always functions as intended. In addition, the dual cushioning effect of the compression spring 603 and the elastic rubber pad 604 significantly reduces vehicle bumps when vehicles pass over the speed bump, improving passenger comfort, especially for public transportation vehicles such as buses and ambulances, minimizing impact on passengers and ensuring their safety and comfort. The entire speed bump mechanism 600 has a reasonable design structure, with tight and stable connections between components. The sliding fit between the T-shaped slide 602 and the T-slot, as well as the connection method of the compression spring 603, can withstand repeated crushing and impacts from vehicles, ensuring the reliability and durability of the speed bump mechanism 600 during long-term use. Moreover, when the elastic rubber pad 604 wears out significantly due to long-term use, it is relatively easy and quick to replace because it is fixed within the strip groove.

[0046] The deceleration mechanism 600 also includes: a movable screw 605 slidably connected in the central through hole of the I-shaped connecting seat 300, the top and bottom of the central through hole being connected to the T-slot and the lower groove provided on the lower surface of the I-shaped connecting seat 300 respectively; the top of the movable screw 605 is threadedly connected in the internal thread groove at the bottom of the T-shaped slide 602, and the screw head 606 at the bottom of the movable screw 605 is engaged in the top surface inside the internal thread groove.

[0047] The movable screw 605 is threaded at the top into the internal threaded groove at the bottom of the T-shaped slide 602. This adds another layer of mechanical connection between the T-shaped slide 602 and the I-shaped connecting seat 300, in addition to the sliding engagement of the compression spring and the T-shaped groove. This enhances the stability of the T-shaped slide 602 on the I-shaped connecting seat 300, preventing horizontal displacement or swaying of the T-shaped slide 602 under repeated vehicle pressure or other external forces. It also prevents the T-shaped slide 602 from detaching from the T-shaped groove, ensuring the overall structural stability of the deceleration ridge mechanism. The movable screw 605 is slidably connected within the central through hole of the I-shaped connecting seat 300, and the screw head 606 is engaged on the top surface inside the internal threaded groove. This provides precise guidance and positioning for the vertical movement of the T-shaped slide 602. This allows the T-shaped slide 602 to move smoothly along the direction of the movable screw 605 when sliding up and down under the action of the compression spring, preventing tilting or offset and ensuring the normal operation of the deceleration ridge mechanism. The movable screw 605 and the T-shaped slide 602 are connected by a thread. This connection method facilitates disassembly and installation, and allows for adjustment of the horizontal height and buffering performance of the deceleration ridge mechanism 600. By fine-tuning the thread of the movable screw 605, the relative position and connection strength between the T-shaped slide 602 and the I-shaped connecting seat 300 can be changed, thereby adjusting the buffering performance of the deceleration ridge and improving the maintainability and adaptability of the deceleration ridge mechanism.

Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
