Description

Technical Field

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

[0002] Bridge expansion joints are all designed using hot-rolled, integrally formed, special-shaped steel. Bridge expansion joints are modular, consisting of side beams, center beams, cross beams, and linkages. The integration of the expansion joint and the beam into a strong, integrated whole is undoubtedly a key factor in improving their effectiveness. Other types of bridge expansion joints, besides modular expansion joints, often lack sufficient fixation and integration with the bridge deck, resulting in less than ideal results.

[0003] Even for continuous bridge decks, cracks often appear in the surface pavement. Therefore, it is necessary to pre-cut the bridge deck, set the joint, and then place the expansion joint adjustment device in the gap. The metal ring on the expansion joint adjustment device is connected to the steel bar at the cut on the bridge through straight bars to improve the tightness of the connection. Since the metal rings on the adjustment devices for existing bridge expansion joints are welded to the crossbeams and cannot be moved, they cannot be tightened after being connected to the steel bars on the bridge, resulting in an insufficient connection between the bridge expansion joint and the bridge. Therefore, this application proposes an expansion joint adjuster. Summary of the Invention

[0004] The purpose of the utility model is to propose an expansion joint adjuster to address the problem in the background technology that the metal rings on the existing adjustment devices for bridge expansion joints are welded to the crossbeams and cannot move. After being connected to the steel bars on the bridge, they cannot be tightened, resulting in insufficient connection between the bridge expansion joint and the bridge.

[0005] The technical solution of the present invention is: an expansion joint adjuster, comprising a crossbeam and a steel ring arranged on the crossbeam, the steel ring is used to connect with the steel bars on the bridge, an adjustment device is provided between the crossbeam and the steel ring, the adjustment device is used to adjust the distance between the crossbeam and the steel ring, and a metal cover plate for covering the expansion joint is provided on the crossbeam.

[0006] Optionally, the adjusting device includes a connecting plate, a connecting plate welder is on the crossbeam, a limiting plate is welded on the connecting plate, a slider is slidably connected to the limiting plate, the slider is fixedly connected to a straight plate, and a steel ring is welded on the straight plate.

[0007] Optionally, an adjusting block is welded on the straight plate, a stud is threadedly connected to the adjusting block, and a screw head is fixedly connected to one end of the stud.

[0008] Optionally, a plurality of threaded holes are provided on the crossbeam, and the threaded holes are threadedly connected to one end of the stud.

[0009] Optionally, the crossbeam is hinged with a group of connecting blocks, a metal cover plate is welded to the connecting blocks, and the top of the metal cover plate is an arc surface.

[0010] Optionally, a rectangular groove is formed on the metal cover, and a group of circular holes are formed on the metal cover at the rectangular groove.

[0011] Optionally, a transverse plate is welded on the transverse beam, and the transverse beam, the transverse plate, the limit plate slider and the straight plate are all cast in one piece.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] By turning the screw head with a tool, the adjusting block is driven to move under the action of the stud and the adjusting block, thereby driving the straight plate and the steel ring to move horizontally. After the steel ring is connected to the steel bars on the bridge, it is tightened, so that the expansion joint of the bridge deck is connected to the bridge more closely and fully. A metal cover plate for covering the expansion joint is provided on the beam. The metal cover plate can not only prevent some expansion joints from being blocked, but also has a decorative effect.
