Description

A high-stability prefabricated bridge Technical Field

[0001] This invention relates to the field of bridges, and more specifically, to a highly stable prefabricated bridge. Background Technology

[0002] Traditional cast-in-place bridge construction methods suffer from numerous drawbacks, including lengthy construction periods, large on-site workloads, significant environmental disturbance, high reliance on manual labor, and high carbon emissions. They fail to meet the core demands of modern engineering for efficient, green, and high-quality construction. To overcome these shortcomings, prefabricated bridge technology has emerged. This technology combines factory prefabrication with on-site assembly, which not only significantly shortens the construction cycle but also improves the quality of individual bridge components and reduces dust pollution at the construction site.

[0003] However, existing prefabricated bridges have poor stability in actual engineering applications. The splicing positions of components lack stable and fixed structures, and there is a lack of mutual cooperation and interlocking between components. Stability and matching can only be remedied by additional on-site pouring, resulting in poor bridge stability and integrity. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a highly stable prefabricated bridge, which can quickly and conveniently assemble the bridge, and the assembled bridge is fixed and interlocked by connecting components, thereby improving the overall stability of the bridge.

[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a highly stable prefabricated bridge, including bridge decks, precast piers, and connecting components. The connecting components include bearing seats, panel connectors, and side supports. Multiple bridge decks are arranged sequentially, and adjacent bridge decks are connected by panel connectors. Multiple bearing seats are connected at the connection points of two adjacent bearing seats. The bottom of some of the bearing seats is connected to the precast piers. One end of the side support is connected to the side of the precast pier, and the other end of the side support is connected to the bottom of the bridge deck.

[0006] In a preferred embodiment of the present invention, the panel connector includes a connecting block, a pressing block, and a side clamping block. Slots are provided on both sides of the connecting block. The pressing block is inserted into the slots, and the bridge panel is inserted into the slots, with the bridge panel abutting against the pressing block. Clamping grooves are provided at the upper and lower ends of the slots, and the side clamping block is slidably connected to the clamping grooves. Connecting rods are connected to the upper and lower ends of the pressing block, and extrusion blocks are connected to the connecting rods. A first inclined surface is provided on the side of the extrusion block, and a second inclined surface is provided on the side clamping block. The first inclined surface and the second inclined surface are in contact.

[0007] In a preferred embodiment of the present invention, the receiving seat corresponds one-to-one with the panel connector, and the receiving seat supports the bottom of the front panel and is located below the connecting block. Both the front and rear ends of the receiving seat are provided with baffles, and the baffles are provided with locking grooves, through which the locking plate passes.

[0008] In a preferred embodiment of the present invention, auxiliary support members are respectively provided on both sides of the bottom of the bearing seat that is not connected to the precast bridge pier. The auxiliary support members include a side top rod and a top seat. The side top rod is hinged to the lower corner of the bearing seat, and the top seat is fixed to one end of the side top rod. The top seat abuts against the bottom of the bridge deck.

[0009] In a preferred embodiment of the present invention, a slot is provided at the bottom of the receiving seat, a protrusion is inserted into the slot, and the other end of the side push rod abuts against the bottom of the protrusion.

[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] As shown in Figures 1-5, the embodiment provides a highly stable prefabricated bridge, including bridge deck 1, precast piers 2, and connecting components. The connecting components include bearing seats 31, panel connectors, and side supports. Multiple bridge decks 1 are arranged sequentially, and adjacent bridge decks 1 are connected by panel connectors. Multiple bearing seats 31 are connected at the connection points of two adjacent bearing seats 31. The bottom of some bearing seats 31 is connected to the precast piers 2. One end of the side support is connected to the side of the precast pier 2, and the other end of the side support is connected to the bottom of the bridge deck 1.

[0017] During bridge assembly, adjacent bridge deck panels 1 are inserted into the panel connectors, which clamp the adjacent bridge deck panels 1 together for fixation. The support seat 31 provides support for the bridge deck panels 1 and the bridge deck connectors, improving the stability of the connection. Precast piers 2 are connected to the bottom of the support seat 31, and side supports connect from the precast piers 2 to the bottom of the bridge deck panels 1, providing further support for the bridge deck panels 1, improving their overall stability and preventing breakage or displacement during use.

[0018] Furthermore, the panel connector includes a connecting block 4, a pressing block 42, and a side clamping block 43. The connecting block 4 has slots 41 on both sides. The pressing block 42 is inserted into the slot 41, and the bridge panel 1 is inserted into the slot 41 and abuts against the pressing block 42. The upper and lower ends of the slot 41 are provided with clamping grooves. The side clamping block 43 is slidably connected in the clamping grooves. The upper and lower ends of the pressing block 42 are connected with connecting rods 44. The connecting rods 44 are connected with extrusion blocks 45. The side of the extrusion block 45 is provided with a first inclined surface, and the side clamping block 43 is provided with a second inclined surface. The first inclined surface and the second inclined surface are in contact.

[0019] The bridge panel 1 is inserted into the slot 41, and the end clamping block 42 of the bridge panel 1 pushes inward, causing the clamping block 42 to shift. The moving clamping block 42 drives the extrusion block 45 to move via the connecting rod 44. The extrusion block 45 engages with the second inclined surface on the side clamping block 43 through its first inclined surface, causing the side clamping block 43 to move towards the bridge panel 1. The movement of the two side clamping blocks 43 clamps the bridge panel 1, improving the stability of the connection.

[0020] Furthermore, the receiving seat 31 corresponds one-to-one with the panel connector, and the receiving seat 31 supports the bottom of the front panel and is located below the connecting block 4. Both the front and rear ends of the receiving seat 31 are provided with baffles 32, and the baffles 32 have locking grooves 33. A locking plate passes through the two locking grooves 33. When adjacent bridge panels 1 are connected by the panel connector, the receiving seat is supported by the connecting block 4 and the bottom of the bridge panel 1. Simultaneously, after the locking plate is inserted into the locking groove 33, the locking plate blocks the connection between the bridge panel 1 and the connecting block 4, preventing the joint position from being affected during subsequent use.

[0021] Furthermore, auxiliary support members are respectively provided on both sides of the bottom of the bearing seat 31 which is not connected to the precast bridge pier 2. The auxiliary support members include a side top rod 34 and a top seat 35. The side top rod 34 is hinged to the lower corner of the bearing seat 31, and the top seat 35 is fixed to one end of the side top rod 34 and abuts against the bottom of the bridge deck 1.

[0022] Furthermore, a slot 36 is provided at the bottom of the receiving seat 31, and a protrusion 37 is inserted into the slot 36. The other end of the side push rod 34 abuts against the bottom of the protrusion 37.

[0023] The top seat 35 in the auxiliary support is lifted to the bottom of the bridge panel 1, and then the protrusion 37 is inserted into the slot 36. The bottom of the protrusion 37 abuts against the side top rod 34, providing support for the side top rod 34 and the top seat 35, making the bridge panel 1 more stable during daily use.

[0024] Furthermore, a fixed channel 21 is provided inside the precast pier 2, and a fixed column 22 is inserted into the fixed channel 21. The side support includes a support rod 23 and a side bracket 24. An insertion hole is provided on the side of the precast pier 2, which is connected to the fixed channel 21. One end of the support rod 23 is inserted into the insertion hole, and the other end of the side bracket 24 is supported on the bottom of the bridge deck 1.

[0025] Furthermore, the bottom of the fixing column 22 is tapered, the fixing channel 21 connects to the top of the precast pier 2, and the upper end of the fixing column 22 abuts against the bottom of the support seat 31.

[0026] During the process of the fixed column 22 being inserted into the fixed channel 21, the support rod 23 is pushed outward, so that the support rod 23, along with the side bracket 24, pushes to the bottom of the bridge deck 1, providing support for the bridge deck 1. At the same time, when the fixed column 22 is pressed into a fixed position by the receiving seat 31, the support rod 23 cannot be retracted, thus maintaining continuous support for the bridge deck 1.

[0027] The bridge deck panels 1 are connected by panel connecting components, which interlock the bridge deck panels 1, making adjacent bridge deck panels 1 a whole. The support seat 31 provides support and further fixation for the bridge deck panels 1 and the panel connecting components. After the bridge deck panels 1 are connected, the auxiliary support components on the support seat 31 and the side support components set on the precast piers 2 provide further support for the bottom of the bridge deck panels 1, improving the overall stability of the bridge and preventing the bridge components from shifting during use.

[0028] Other techniques in this embodiment are based on existing technologies.
