Description

Technical Field

[0001] This utility model relates to a steel bridge deck assembly and connection structure, belonging to the field of steel bridge construction technology. Background Technology

[0002] The steel bridge deck is the load-bearing structure that directly bears the pressure of vehicle wheels. The steel bridge decks of short-span bridges are connected by lap joints, which can easily lead to stress concentration at the lap joints and may slip under long-term loads.

[0003] Current technology is not comprehensive and has the following drawbacks: vehicle moving loads cause periodic out-of-plane deformation of the bridge deck; the splice joints become weak points due to structural discontinuity; the splice joints of steel bridge decks are high-risk areas for fatigue cracks; the connection between two bridge decks has poor stability; it is impossible to reduce bridge deck settlement and deformation; and frequent closures for maintenance are unavoidable.

[0004] To solve one of the above problems, a steel bridge deck assembly and connection structure is urgently needed. Utility Model Content

[0005] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to achieve rapid assembly, shorten the construction period, and improve the shear resistance of the bridge deck connection through the coordinated cooperation of the connecting plate, reinforcing pipe, left extension rod, right extension rod and end fixing seat A, thereby improving the stability of the connection between the two bridge decks, reducing bridge deck settlement and deformation, and avoiding frequent closure for maintenance. Therefore, a steel bridge deck assembly and connection structure is provided.

[0006] The steel bridge deck assembly and connection structure of this utility model includes a left bridge deck and a right bridge deck arranged adjacent to each other. A connecting plate is provided below the splice of the left and right bridge decks. The connecting plate is characterized by having multiple sets of reinforcing pipes spaced apart. A first connector is provided on the lower surface of the left bridge deck, which connects the connecting plate to the left bridge deck. The first connector also connects a left extension rod to the end of the reinforcing pipe through the first connector. A second connector is provided on the lower surface of the right bridge deck, which connects the connecting plate to the right bridge deck. The second connector also connects a right extension rod to the end of the reinforcing pipe through the second connector. The left extension rod is connected to the left bridge deck through an end fixing seat A, and the right extension rod is connected to the right bridge deck through an end fixing seat B.

[0007] When connecting the left and right bridge decks, a connecting plate on the left bridge deck is used to connect to the left bridge deck, and a left extension rod is connected to the end of the reinforcing pipe via a first connector. Simultaneously, a second connector is used to connect the connecting plate to the right bridge deck, and a right extension rod is connected to the end of the reinforcing pipe via a second connector. The left extension rod is slidably connected to the left bridge deck via end fixing seat A, and the right extension rod is slidably connected to the right bridge deck via end fixing seat B. This reduces installation accuracy requirements, enables rapid assembly, and shortens the construction period. The bridge deck connection, through the coordinated operation of the connecting plate, reinforcing pipe, left extension rod, right extension rod, and end fixing seat A, enhances the shear resistance of the connection, thereby improving the stability of the connection between the two bridge decks. A stable connection reduces bridge deck settlement and deformation, avoiding frequent closures for maintenance.

One end of the left extension rod is inserted between inner rod A and the outer sleeve, and one end of the right extension rod is inserted between the outer sleeve and the inner rod B. Improving the shear resistance at the connection point can enhance the stability of the connection between the two bridge decks, reduce bridge deck settlement and deformation, and avoid frequent closures for maintenance.

[0010] In any of the above embodiments, preferably, the first connecting member includes a first screw, a first nut, a second screw, and a second nut. The upper end of the first screw passes through an outer sleeve, a left extension rod, and a connecting plate and is welded to the left bridge deck. The lower end of the first screw is threaded to the first nut.

The upper end of the fourth screw passes through an outer sleeve, an inner insert rod B, a right extension rod, and a connecting plate and is welded to the left bridge deck. The lower end of the fourth screw is threaded to the fourth nut.

[0011] When connecting the left and right bridge decks, the first, second, third, and fourth screws are pre-welded to the left and right bridge decks, respectively. The reinforcing pipe is then welded to the connecting plate. The left and right extension rods are simply inserted from both ends of the reinforcing pipe, and then the first, second, third, and fourth screws are used to connect the left extension rod, reinforcing pipe, right extension rod, right bridge deck, and connecting plate together. Finally, end fixing seats A and B are fitted onto the left and right extension rods, respectively, and then welded to the left and right bridge decks, respectively. This rapid assembly and shortened construction time are achieved.
