Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an expansion joint bridge plate. Background Art

[0002] Before the expansion joints were constructed, asphalt was already laid on both sides of the bridge deck and within the expansion joints. During construction, the asphalt within the expansion joints needed to be chiseled away, creating a groove. This was then replaced with a bridge slab. This not only facilitated the passage of construction vehicles, allowing them to pass through the groove smoothly, but also effectively protected the stirrups embedded in the expansion joints, preventing damage to finished and semi-finished products during construction.

[0003] However, the currently used bridge decks present several practical problems during construction. First, the decks are prone to movement, increasing the risk of accidents. Second, due to their suspended state, the decks are prone to sag in the middle. These issues not only impact construction safety but also the quality of expansion joint construction. Therefore, more effective fixing measures and support designs are needed when using bridge decks to improve their stability and load-bearing capacity, ensuring a safe and smooth construction process. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide an expansion joint bridge plate, which solves the problem that the traditional bridge plate is easily displaced due to load or vehicle passage, and the bridge plate part above the groove is easily sunken.

[0005] The technical solution adopted by the present invention to solve the above problems is: an expansion joint bridge plate, laid above the expansion joint between two viaducts, the upper end of the expansion joint is provided with a groove, including a plate body, the plate body includes at least two parallel and spaced ribs, and connecting ribs for welding and fixing the ribs to each other, the ribs include a plane portion located in the middle and two transition portions continuous at both ends of the plane portion, the upper end surface of the plane portion is horizontal, the two transition portions are respectively placed at the upper end surfaces of the two viaducts, and the upper end surfaces thereof are inclined surfaces, which are used for the inclined transition of the upper end surface of the plane portion to the upper end surfaces of the two viaducts, two support rods are hinged between the two adjacent ribs, the movable ends of the support rods are hinged with support blocks, the bottom surfaces of the two support blocks are against the bottom surface of the groove, and the outer side surfaces of the two support blocks are respectively against the two side walls of the groove.

[0006] Compared to existing technologies, this bridge deck is composed of multiple parallel, spaced-apart ribs, increasing the board's strength and stability. The ribs are designed to include a planar portion and a transition portion. The planar portion provides support, while the transition portion is angled. This allows the upper end surface of the planar portion to transition more smoothly to the upper end surface of the viaduct, reducing impact during vehicle travel and the likelihood of dents and displacement, allowing the board to better adapt to the height difference between the viaducts on both sides. Adjacent ribs are connected by support rods, adding a degree of flexibility. The support blocks tightly contact the bottom and side walls of the grooves, preventing the deck from shifting and causing accidents when vehicles pass over it, thus increasing safety.

[0007] Furthermore, the connecting ribs are welded at intervals on the upper end surfaces of the plane portion and the transition portion, so that the tire is not easy to slip when rolling on the plane portion and the upper end surface of the transition portion.

[0008] Furthermore, the connecting bars are cylindrical steel bars, which are easier to obtain at the construction site, thus reducing manufacturing costs and facilitating welding.

[0009] Furthermore, the support rod is hinged between two adjacent ribs via a rotating shaft, and both ends of the rotating shaft are rotatably connected to the two adjacent ribs.

[0010] Furthermore, the support rod includes a first connecting rod, a second connecting rod, and a third connecting rod. One end of the first connecting rod is hinged to the rotating shaft, and both ends of the second connecting rod are provided with external threads. The external threads at both ends of the second connecting rod have opposite thread directions and are respectively connected to the other end of the first connecting rod and one end of the third connecting rod. The support block is hinged to the other end of the third connecting rod, and the second connecting rod is rotated to make the third connecting rod closer to or away from the first connecting rod. By rotating the second connecting rod, the distance between the third connecting rod and the first connecting rod can be adjusted, that is, the length of the support rod can be adjusted.

[0011] Furthermore, a knob portion is provided in the middle of the second connecting rod, and the knob portion is hexagonal as a whole, so that it is convenient for an adjustable wrench to clamp the two opposite planes on the knob portion to apply torque, which is convenient for operation and high precision.
