Embodiment Construction
[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement the invention with reference to the description.
[0054] It should be understood that terms such as "having", "comprising" and "including" as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0055] like Figure 1-Figure 6 As shown, the present invention provides a highway bridge expansion joint device, comprising:
[0056] Road body 1:
[0057] A fixed anchor 2, one end of the fixed anchor 2 is fixedly connected to the inside of the road body 1;
[0058] beam 3, the outer wall of the beam 3 is fixedly connected with the other end of the anchor 2;
[0059] A buffer device 4, the two ends of the buffer device 4 are respectively fixedly connected to the inner walls of the two adjacent beams 3;
[0060] The cross beam slide rail 34 is located ...

The invention discloses a road bridge expansion joint device, comprising: a road body: a fixed anchor, one end of the fixed anchor is fixedly connected to the inside of the road body; a beam, the outer wall of the beam is connected to the other end of the fixed anchor Fixed connection; buffer device, the two ends of the buffer device are respectively fixedly connected to the inner walls of two adjacent beams; beam slide rail, the beam slide rail is located at the bottom end of the beam, and the beam and the beam The sliding connection between the above-mentioned beam slide rails; through the designed beam slide rail, the beam connected to the road body slides on the beam slide rail, thereby neutralizing the force generated when the vehicle passes through the road body and protecting the safety of the road body. At the same time, the service time of the expansion joint is extended, and the vibration generated by the buffer device will shake off the dust accumulated in the expansion joint, avoiding the accumulation of dust to block the expansion joint, resulting in the inability to discharge the accumulated water on the road.
Description
technical field [0001] The present invention relates to the technical field of expansion joint devices, and more particularly, to a highway bridge expansion joint device. Background technique [0002] Expansion joints refer to expansion joints that are usually set between two beam ends, between beam ends and abutments, or at the hinge position of bridges, as well as on the lateral direction of the road surface, in order to meet the requirements of bridge deck or road surface deformation. The expansion joints are required to be able to expand and contract freely in both directions parallel and perpendicular to the axis of the bridge, and are firm and reliable. The vehicles should run smoothly without sudden jumps and noises; they should be able to prevent rainwater and garbage and soil from infiltrating and blocking; installation, inspection, and maintenance , Elimination of dirt should be simple and convenient. The function of the expansion joint is to adjust the displaceme...
