Description

Technical Field

[0001] This utility model relates to the field of bridge deck technology, and more specifically to a road and bridge deck joint reinforcement device. Background Technology

[0002] Bridge panel joints refer to the sections connecting adjacent panels in a bridge or road structure, typically located at the four corners and center. In bridge, viaduct, and tunnel engineering, bridge panel joints are crucial components connecting different parts, and their quality and stability directly impact the service life and safety of the bridge or road. However, current bridge panel joint reinforcement devices traditionally use bolts to connect adjacent panels via threaded rotation. But with conventional threaded connections, the threaded rods can loosen over time, leading to instability and requiring frequent maintenance and reinforcement. Utility Model Content

[0003] The purpose of this utility model is to provide a road and bridge panel node reinforcement device to avoid the loosening of traditional threaded connections over time.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A road and bridge panel node reinforcement device includes multiple road and bridge panels. Each of the four corners of the top surface of the road and bridge panel is provided with a corner groove. Adjacent corner grooves together form an installation groove. A connecting plate is placed in the installation groove. A locking post is fixedly installed in the corner groove. The connecting plate is provided with a locking groove corresponding to the locking post.

[0006] Furthermore, a placement slot is provided at the top of the mounting slot, and a top plate is placed in the placement slot.

[0007] Furthermore, the top plate is bolted into the placement slot.

[0008] Furthermore, the top of the connecting plate is provided with a plug-in slot.

[0009] Furthermore, a plug rod is provided on the top of the top plate directly opposite the plug slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model adopts a locking post and locking groove matching method, which avoids the loosening phenomenon caused by the long-term threaded connection, enhances the long-term stability of the node, and improves the safety of the entire road and bridge structure.

[0017] like Figures 1 to 4 As shown, a road and bridge panel node reinforcement device includes multiple road and bridge panels 1. Each of the four corners of the top surface of the road and bridge panel 1 is provided with a corner groove 2. Adjacent corner grooves 2 together form an installation groove 3. A connecting plate 4 is placed in the installation groove 3. A locking post 5 is fixedly installed in the corner groove 2. The connecting plate 4 is provided with a locking groove 6 corresponding to the locking post 5.

[0018] The top of the mounting groove 3 is provided with a placement groove 7, and a top plate 8 is placed in the placement groove 7. By setting the placement groove 7 and placing the top plate 8 on the top of the mounting groove 3, additional protection is provided for the connecting plate 4 to prevent external environmental factors from damaging the internal structure.

[0019] The top plate 8 is installed in the placement groove 7 by bolts 9.

[0020] The top of the connecting plate 4 is provided with a plug-in slot 10.

[0021] A plug rod is provided on the top of the top plate 8, directly opposite the plug groove 10; the cooperation between the plug rod and the plug groove 10 can effectively resist the shear force in the horizontal direction, and improve the load-bearing capacity of the node under vehicle load.

[0022] During installation, the connecting plate 4 is placed in the mounting groove 3 formed by the adjacent corner grooves 2, ensuring that the engaging groove 6 is correctly aligned with the engaging post 5 and fully embedded; the top plate 8 is placed in the placement groove 7, and the plug rod on the top plate 8 is inserted into the plug groove 10 of the connecting plate 4 to form a tight connection, and the top plate 8 is firmly fixed to the placement groove 7 with bolts 9 to complete the installation; during disassembly, the bolts 9 are removed, the top plate 8 is taken out, and the connecting plate 4 is removed from the engaging post 5 through the plug groove 10, thereby completing the disassembly of the connection structure between each bridge deck 1.

[0023] This invention significantly improves the mechanical strength of the nodes through a snap-fit ​​structure and plug-in design, enabling them to withstand greater loads and stress variations. Furthermore, the use of a connection method that prevents loosening reduces the need for regular maintenance, thereby lowering long-term maintenance costs.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
