Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and in particular to a high-strength, high-durability bridge deck concrete pavement structure. Background Technology

[0002] High-strength, high-durability concrete pavement structures play a crucial role in modern bridge construction, bringing numerous significant practical benefits to bridge engineering. Leveraging its inherent characteristics, this structure effectively enhances the load-bearing capacity of the bridge deck, sufficient to cope with increasing traffic flow and the pressure of frequent heavy vehicle traffic, ensuring the bridge maintains good working condition over long-term use. Simultaneously, its excellent durability greatly extends the service life of the bridge deck, reducing the high costs and time associated with frequent maintenance and pavement replacement, and minimizing disruption to traffic flow.

[0003] Typical bridge deck concrete pavement structures consist of formwork, fixing mechanisms, and reinforcing bars, which are laid and shaped in a mold. The formwork serves as the reference frame for concrete forming. It is pre-assembled to form a spatial outline that matches the design dimensions of the bridge deck, providing lateral constraints for the poured concrete. The fixing mechanism uses bolts to tightly connect the formwork to the main structure of the bridge to prevent the formwork from shifting or deforming. The reinforcing bars are laid inside the formwork according to the design spacing and specifications to form an overall load-bearing skeleton.

[0004] In existing technologies, the connections between templates in some devices are loose and the overall integrity is poor. During the concrete pouring process, displacement or deformation can easily occur due to vibration impact and lateral pressure, making it difficult to accurately control the pouring shape. At the same time, the templates themselves have insufficient load-bearing capacity and are prone to bulging when facing high concrete pressure, failing to provide a stable closed space for concrete pouring. This affects the forming quality and mechanical properties of the pavement structure, making it difficult to meet the requirements of high strength and high durability. Therefore, a high-strength and high-durability bridge deck concrete pavement structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-strength, high-durability bridge deck concrete pavement structure, which aims to improve the problems of loose connection between templates and poor overall integrity in some devices of the existing technology, making it difficult to accurately control the pouring shape, and the template bearing capacity is insufficient, which easily leads to bulging due to concrete pressure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-strength, high-durability bridge deck concrete pavement structure includes an outer bridge deck, an inner bridge deck fixedly connected to the inner bridge deck, a limiting mechanism on the top of the inner bridge deck, and a fixing mechanism on the top of the outer bridge deck. The limiting mechanism includes a long template, the bottom of which is supported on both sides of the top of the inner bridge deck. A connecting plate is snapped onto an adjacent side of the long template, and a wide template is fixedly connected to an adjacent side of the connecting plate. A lower screw is slidably connected inside the connecting plate, a support block is fixedly connected to one end of the lower screw, an adjusting bolt is rotatably connected to the top inner side of the support block, a moving block is slidably connected to the outside of the adjusting bolt, an upper screw is fixedly connected to the outside of the moving block, a connecting assembly is threaded onto the outside of the lower screw, and a snapping assembly is fixedly connected to the outside of the wide template. Through the above technical solution: the long template, connecting plate and wide template can be combined to form the boundary of the pouring space. The sliding cooperation of the lower screw and upper screw in the connecting plate with the adjustment of the support block, adjusting bolt and moving block can flexibly adjust the distance between the templates.

Through the above technical solution: the fixing plate provides stable support for the buckle, the buckle limits the horizontal and vertical steel bars, the abutment block enhances the load-bearing capacity of the buckle, and the tie wire connects the vertical and horizontal steel bars with the shear studs, forming a solid steel skeleton foundation, which provides a strong support frame for the bridge deck structure.

Through the above technical solution: the vertical steel bars are clamped in the buckle to further ensure their own position stability, the bottom of the shear stud is fixed to the top of the inner bridge deck, and the top supports the vertical and horizontal steel bars, which can transfer the force on the steel skeleton to the inner bridge deck, realize the effective transmission of force, and enhance the integrity of the bridge deck structure.

[0009] As a further description of the above technical solution: The external thread of the buckle is connected to the outside of the long template, the external part of the vertical steel bar is inserted into the inside of the wide template, and the external part of the horizontal steel bar is inserted into the inside of the long template. The above technical solution involves a snap-fit ​​connection between the clip and the long template, with vertical reinforcing bars inserted into the wide template and horizontal reinforcing bars inserted into the long template. This tightly integrates the fixing mechanism and the restraining mechanism into a single unit, preventing relative movement between them and improving the overall stability of the structure.

[0010] As a further description of the above technical solution: The snap-fit ​​assembly includes a snap-fit ​​plate, which is externally fixedly connected to the top of the wide template, and a snap-fit ​​groove is provided on the bottom inner side of the wide template; The above technical solution, through the cooperation of the card plate and the card slot, enables the wide formwork to be spliced ​​quickly and accurately, reduces the deviation in the splicing process, improves the efficiency and accuracy of the wide formwork installation, and lays a good foundation for the subsequent pouring work.

[0011] As a further description of the above technical solution: The connecting assembly includes a lower nut and an upper nut.

The outside of the lower nut is supported on the outside of the connecting plate, and the outside of the upper nut is supported on the outside of the connecting plate. The above technical solution involves threading the lower nut and upper nut to the lower screw and upper screw respectively and supporting them on the outside of the connecting plate.

[0012] As a further description of the above technical solution: By placing the two wide templates vertically, the retaining plate of the bottom wide template is engaged with the slot of the top wide template. Then, the lower screw is placed inside the bottom connecting plate, and the upper screw is placed inside the top connecting plate. The adjusting bolt is rotated to move the moving block toward the support block, thus fixing the two wide templates together. The above technical solution involves two wide templates being vertically connected via clamping plates and slots. The templates are then fixed by adjusting the lower and upper screws, adjusting the bolts, and adjusting the moving blocks. This creates a vertically stable frame structure that meets the boundary requirements of different pouring areas and enhances the adaptability of the template structure.

[0013] As a further description of the above technical solution: By intersecting and fixing the vertical steel bars with the horizontal steel bars, a grid is formed at the connection between the vertical steel bars and the horizontal steel bars, and the connection is connected to the outside of the shear stud by the tie wire; The above technical solution involves vertical and horizontal reinforcing bars intersecting and fixing to form a grid, which is then connected to the outside of the shear studs by tie wire.

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.

[0019] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a high-strength, high-durability bridge deck concrete pavement structure, including an outer bridge deck 1, with an inner bridge deck 2 fixedly connected inside the outer bridge deck 1. The double-layer structure of the outer bridge deck 1 and the inner bridge deck 2 can significantly improve the overall impact resistance and load-bearing strength of the bridge deck. The inner bridge deck 2 is used for paving concrete, and the outer bridge deck 1 is used for installing railings. A limiting mechanism 3 is provided on the top of the inner bridge deck 2. The limiting mechanism 3 can accurately control the shape of the concrete during pouring and avoid bulging or deformation problems. A fixing mechanism 4 is provided on the top of the outer bridge deck 1. The fixing mechanism 4 can enhance the connection stability of various components of the bridge deck and extend the service life of the bridge deck. The limiting mechanism 3 includes a long template 31, the bottom of which is supported on both sides of the top of the inner bridge deck 2. The long template 31 can provide longitudinal boundary support for concrete pouring from both sides to prevent the concrete from flowing laterally. A connecting plate 32 is snapped onto the adjacent side of the long template 31. The connecting plate 32 can connect the long template 31 and the wide template 33 into an integral frame to improve the integrity of the template structure. The wide template 33 is fixedly connected to the adjacent side of the connecting plate 32. The wide template 33 can limit the concrete pouring range laterally and form a closed pouring space with the long template 31. The connecting plate 32 is internally slidably connected to a lower screw 34, which can slide and adjust its position within the connecting plate 32 to provide a lateral support point for fixing the template. One end of the lower screw 34 is fixedly connected to a support block 35, which provides a stable installation base for the adjusting bolt 36 and ensures the stability of the structure during adjustment. The top inner side of the support block 35 is rotatably connected to an adjusting bolt 36, which can drive the moving block 37 to move by rotating, thereby adjusting the template spacing. The adjusting bolt 36 is externally slidably connected to a moving block 37, which can change its position under the action of the adjusting bolt 36, thereby driving the upper screw 38 to move synchronously. The movable block 37 is externally fixedly connected with an upper screw 38, which cooperates with a lower screw 34 to fix the template from the top and bottom, enhancing the template's load-bearing capacity. The lower screw 34 is externally threadedly connected with a connecting component 6, which can tightly fix the lower screw 34 to the connecting plate 32 to prevent the template from shifting during the pouring process. The wide template 33 is externally fixedly connected with a snap-fit ​​component 5, which can realize the rapid splicing and positioning between wide templates 33, improving the template installation efficiency. Specifically, the outer bridge deck 1 is internally fixedly connected to the inner bridge deck 2. The double-layer structure significantly improves the overall impact resistance and load-bearing capacity of the bridge deck. The inner bridge deck 2 is responsible for concrete paving, while the outer bridge deck 1 is used for fence installation. The inner bridge deck 2 is equipped with a limiting mechanism 3 at the top, which can accurately control the concrete pouring shape to avoid bulging or deformation. The outer bridge deck 1 is equipped with a fixing mechanism 4 at the top, which can enhance the connection stability of various bridge deck components to extend service life. The bottom of the long template 31 in the limiting mechanism 3 is supported on both sides of the top of the inner bridge deck 2, providing longitudinal boundary support for concrete pouring from both sides to prevent lateral flow of concrete. The connecting plate 32, which is snapped onto the side of the long template 31, connects the long template 31 and the wide template 33 into an integral frame to improve the overall integrity of the template structure. The wide template 33, which is fixedly connected to the side of the connecting plate 32, limits the concrete pouring range from the side and forms a closed pouring space with the long template 31. The lower screw 34, which is slidably connected inside the connecting plate 32, can slide and adjust its position within the connecting plate 32 to provide a lateral support point for template fixing. The support block 35, which is fixedly connected to one end of the lower screw 34, provides a stable installation base for the adjusting bolt 36 to ensure structural stability during adjustment. The adjusting bolt 36, which is rotatably connected to the inner top of the support block 35, drives the moving block 37 to move to adjust the template spacing. The moving block 37, which is slidably connected to the outside of the adjusting bolt 36, changes position under its influence, thereby driving the upper screw 38 to move synchronously. The upper screw 38, which is fixedly connected to the outside of the moving block 37, works with the lower screw 34 to fix the template from the top and bottom to enhance the template's load-bearing capacity. The connecting component 6, which is threaded to the outside of the lower screw 34, tightly fixes the lower screw 34 to the connecting plate 32 to prevent template displacement during pouring. The snap-fit ​​component 5, which is fixedly connected to the outside of the wide template 33, enables rapid splicing and positioning between the wide templates 33 to improve template installation efficiency.

[0020] The snap-fit ​​assembly 5 includes a snap-fit ​​plate 51, which is externally fixedly connected to the top of the wide template 33. The snap-fit ​​plate 51 can precisely engage with the snap-fit ​​slot 52 to ensure accurate connection position of the upper and lower wide templates 33 and avoid misalignment. The bottom inner side of the wide template 33 is provided with a snap-fit ​​slot 52. The cooperation between the snap-fit ​​slot 52 and the snap-fit ​​plate 51 can realize quick positioning between the wide templates 33 and reduce installation errors. The connecting component 6 includes a lower nut 61 and an upper nut 62. The internal thread of the lower nut 61 is connected to the outside of the lower screw 34. By engaging with the lower screw 34, the lower nut 61 can firmly fix the connecting plate 32 to the lower screw 34 to prevent loosening. The internal thread of the upper nut 62 is connected to the outside of the upper screw 38. The upper nut 62 can engage with the upper screw 38 to fix the connecting plate 32 from above, further enhancing the stability of the template. The external support of the lower nut 61 is on the outside of the connecting plate 32. The support of the lower nut 61 on the connecting plate 32 can distribute the force and prevent the connecting plate 32 from being deformed by local pressure. The external support of the upper nut 62 is on the outside of the connecting plate 32. The joint support of the upper nut 62 and the lower nut 61 can make the connecting plate 32 bear the force evenly and improve the overall structural stability. By placing two wide templates 33 vertically, the clamping plate 51 of the bottom wide template 33 is engaged with the groove 52 of the top wide template 33. This engagement method can quickly achieve the vertical positioning of the wide templates 33 and ensure the accuracy of the connection. Then, the lower screw 34 is placed inside the bottom connecting plate 32, and the upper screw 38 is placed inside the top connecting plate 32. The lower screw 34 and the upper screw 38 provide support points for the upper and lower connecting plates 32 respectively, preparing for subsequent fixing. Rotating the adjusting bolt 36 causes the moving block 37 to move towards the support block 35. The rotation of the adjusting bolt 36 can precisely control the moving distance of the moving block 37, fixing the two wide templates 33 together. The final fixed connection enables the wide templates 33 to form a stable vertical frame, providing a reliable boundary for concrete pouring. Specifically, the snap-fit ​​component 5 includes a snap-fit ​​plate 51, which is externally fixed to the top of the wide template 33 and can be precisely snapped into the snap-fit ​​slot 52 to ensure that the connection position of the upper and lower wide templates 33 is accurate and without misalignment. The snap-fit ​​slot 52 opened on the inner side of the bottom of the wide template 33 cooperates with the snap-fit ​​plate 51 to realize the rapid positioning of the wide template 33 and reduce installation errors. The connecting component 6 has a lower nut 61 and an upper nut 62. The lower nut 61 is internally threaded to the outside of the lower screw 34, and the connecting plate 32 is fastened to the lower screw 34 through the threaded engagement to prevent loosening. The upper nut 62 is internally threaded to the outside of the upper screw 38, and cooperates with the upper screw 38 to fix the connecting plate 32 from above, enhancing the stability of the template. The lower nut 61 externally supports the outside of the connecting plate 32, distributing the force and preventing local pressure deformation. The upper nut 62 externally supports the outside of the connecting plate 32, and together with the lower nut 61, they support the connecting plate 32 to ensure that the force is evenly distributed and improve the overall stability. Two wide templates 33 are placed vertically, and the clamping plate 51 of the bottom wide template 33 is inserted into the clamping groove 52 of the top wide template 33. This clamping method quickly achieves vertical positioning of the wide templates 33 and ensures accurate connection. The lower screw 34 is placed inside the bottom connecting plate 32, and the upper screw 38 is placed inside the top connecting plate 32. The two provide support points for the upper and lower connecting plates 32 respectively, preparing for subsequent fixing. The adjusting bolt 36 is rotated to move the moving block 37 towards the support block 35. The moving distance is precisely controlled to fix the two wide templates 33, and finally a stable vertical frame is formed, providing a reliable boundary for concrete pouring.

[0021] Reference Figures 1 to 3 The fixing mechanism 4 includes a fixing plate 41. The bottom of the fixing plate 41 is threadedly connected to the top of the outer bridge deck 1. The fixing plate 41 can be firmly fixed to the outer bridge deck 1 through the threaded connection, providing a stable installation foundation. The top of the fixing plate 41 is fixedly connected to a buckle 42. The buckle 42 can limit the horizontal reinforcing bar 44 and the vertical reinforcing bar 45 to prevent the reinforcing bar from shifting during the pouring process. The buckle 42 is fixedly connected to an external abutment block 43. The abutment block 43 can enhance the structural strength of the buckle 42 and prevent the buckle 42 from deforming due to excessive force. The buckle 42 has a horizontal steel bar 44 inside, which serves as the lateral support for the bridge deck steel reinforcement skeleton, improving the shear resistance and lateral integrity of the bridge deck. The horizontal steel bar 44 is fixedly connected to a vertical steel bar 45. The vertical steel bar 45 and the horizontal steel bar 44 work together to form a steel mesh, which can significantly improve the tensile strength and overall load-bearing capacity of the concrete. The vertical steel bar 45 is fitted with a tie wire 46, which can firmly connect the vertical steel bar 45 and the horizontal steel bar 44 to the shear stud 47, enhancing the connection strength between the steel reinforcement skeleton and the bridge deck. The tie wire 46 is fitted with a shear stud 47 inside, which can effectively transmit the shear force between the bridge deck and the internal structure, preventing relative slippage between the bridge deck and the inner bridge deck 2. The vertical steel bar 45 is snapped into the buckle 42. The buckle 42's snapping of the vertical steel bar 45 can further fix the position of the vertical steel bar 45, ensuring the regularity of the steel mesh. The bottom of the shear stud 47 is fixedly connected to the top of the inner bridge deck 2. This fixed connection transfers the load on the bridge deck to the inner bridge deck 2, dispersing stress. The outer top of the shear stud 47 is supported on the outer top side of the vertical reinforcing bar 45. This support enhances the vertical stability of the reinforcing bar skeleton. The outer top of the shear stud 47 is also supported on the outer top side of the horizontal reinforcing bar 44. This support works synergistically with the support of the vertical reinforcing bar 45, improving the overall stability of the reinforcing bar skeleton. The overall stability of the frame is enhanced by the external threaded connection of the buckle 42 to the outside of the long template 31. This threaded connection can connect the fixing mechanism 4 and the limiting mechanism 3 into a whole, enhancing the overall integrity of the bridge deck structure. The external of the vertical steel bar 45 is inserted into the inside of the wide template 33. The insertion and cooperation between the vertical steel bar 45 and the wide template 33 can further limit the displacement of the steel bar. The external of the horizontal steel bar 44 is inserted into the inside of the long template 31. The insertion and cooperation between the horizontal steel bar 44 and the long template 31 can enhance the connection strength between the steel bar frame and the limiting mechanism 3. By intersecting and fixing the vertical steel bars 45 and the horizontal steel bars 44, a grid is formed at the connection between the vertical steel bars 45 and the horizontal steel bars 44. This grid structure can evenly distribute the load on the bridge deck and improve the crack resistance of the bridge deck. The connection is made to the outside of the shear studs 47 by the tie wire 46. The connection of the tie wire 46 can make the steel mesh and the shear studs 47 form an integral force system, effectively transfer stress and improve the durability of the bridge deck. Specifically, the fixing mechanism 4 includes a fixing plate 41, the bottom of which is threaded to the top of the outer bridge deck 1 and is securely fixed to the outer bridge deck 1 through the threaded connection, providing a stable installation foundation. The buckle 42 fixed to the top of the fixing plate 41 can limit the horizontal steel bar 44 and the vertical steel bar 45 to prevent the steel bar from shifting during pouring. The abutment block 43 fixed to the outside of the buckle 42 enhances the structural strength of the buckle 42 and prevents it from deforming due to excessive force. The horizontal steel bar 44 clamped inside the buckle 42 serves as a lateral support for the bridge deck steel bar skeleton, improving the shear resistance and lateral integrity of the bridge deck. The vertical bars 45 fixed to the outside of the horizontal bars 44 form a steel mesh with the horizontal bars 44, which greatly improves the tensile strength of concrete and the overall bearing capacity. The tie wires 46 sleeved on the outside of the vertical bars 45 firmly connect the vertical bars 45, the horizontal bars 44 and the shear studs 47, which enhances the connection strength between the steel skeleton and the bridge deck. The shear studs 47 sleeved inside the tie wires 46 effectively transfer the shear force between the bridge deck and the internal structure, and prevent the bridge deck and the inner bridge deck 2 from slipping relative to each other. The vertical bars 45 are snapped into the inside of the buckles 42 to further fix their position and ensure the regularity of the steel mesh. The bottom of the shear studs 47 is fixedly connected to the top of the inner bridge deck 2 to transfer the bridge deck load to the inner bridge deck 2 and disperse the stress. The outer top of the shear stud 47 supports the outer top side of the vertical reinforcing bar 45, enhancing the vertical stability of the reinforcing bar skeleton. The outer top of the shear stud 47 also supports the outer top side of the horizontal reinforcing bar 44, working in synergy with the support of the vertical reinforcing bar 45 to improve the overall stability of the reinforcing bar skeleton. The snap fastener 42 is externally threaded to the outside of the long formwork 31, connecting the fixing mechanism 4 and the restraining mechanism 3 into a whole, enhancing the overall integrity of the bridge deck structure. The outer side of the vertical reinforcing bar 45 is inserted into the inside of the wide formwork 33, further restricting the displacement of the reinforcing bar. The outer side of the horizontal reinforcing bar 44 is inserted into the inside of the long formwork 31, enhancing the connection strength between the reinforcing bar skeleton and the restraining mechanism 3. Vertical steel bars 45 and horizontal steel bars 44 are cross-fixed and connected to form a grid at the connection. This grid structure evenly distributes the bridge deck load and improves the bridge deck's crack resistance. The connection is then connected to the outside of shear studs 47 by tie wires 46, so that the steel mesh and shear studs 47 form an integrated force-bearing system, effectively transferring stress and improving the bridge deck's durability.

[0022] Working principle: First, the limiting mechanism 3 is used to construct a closed pouring space. The long template 31 and the wide template 33 are connected to form an integral frame through the connecting plate 32. The clamping plate 51 and the clamping groove 52 of the clamping component 5 cooperate to realize the quick splicing and positioning of the wide template 33. The position is adjusted by sliding the lower screw 34, and the moving block 37 is driven by rotating the adjusting bolt 36 to move the upper screw 38. With the cooperation of the lower nut 61 and the upper nut 62 of the connecting component 6, the template is fixed from the top and bottom, and the concrete pouring shape is precisely controlled to avoid bulging or deformation.

[0023] Meanwhile, the fixing mechanism 4 enhances the connection stability of various bridge deck components. The fixing plate 41 is fixed on the outer bridge deck 1. The buckle 42 limits the horizontal steel bars 44 and vertical steel bars 45 to form a grid structure under the support of the abutment block 43. The steel bar connection is connected to the shear nail 47 by the tie wire 46. The shear nail 47 transmits the load and supports the steel bar skeleton. The buckle 42 is threaded to the long template 31. The horizontal steel bars 44 and vertical steel bars 45 are respectively inserted into the long template 31 and the wide template 33, so that the fixing mechanism 4 and the limiting mechanism 3 form a whole. Combined with the double-layer structure of the outer bridge deck 1 and the inner bridge deck 2, the impact resistance, load-bearing strength and durability of the bridge deck are greatly improved.
