Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, in particular to an adjustable road and bridge expansion joint device. Background Art

[0002] With the continuous development of transportation infrastructure, road and bridge projects play an increasingly important role in people's lives. In road and bridge structures, expansion joint devices are a key component. Their main function is to adapt to the deformation of bridges caused by factors such as temperature changes, concrete shrinkage, creep, and vehicle loads, and to ensure the safety and normal use of bridges. Traditional road and bridge expansion joint devices usually adopt a fixed size and structure design, which has some limitations in actual use. On the one hand, due to the different requirements for expansion joints in different road and bridge structures and usage environments, fixed-size expansion joint devices are difficult to meet diverse needs. On the other hand, with the passage of time and changes in usage conditions, the deformation of roads and bridges may change, and traditional expansion joint devices cannot be effectively adjusted, which can easily lead to failure of the expansion joint function, affecting the service life of roads and bridges and driving safety.

[0003] The sealing strip installed between the two side beams on existing equipment has grooves, which not only cause a large amount of dust and gravel to accumulate, but also destroy the close fit between the sealing strip and the side beam, greatly reducing the sealing performance. In this way, rainwater, debris, etc. can easily invade the expansion joint, accelerate the corrosion and damage of the expansion joint device, and affect its normal expansion and contraction function.

[0004] Therefore, it is urgent to provide an adjustable road and bridge expansion joint device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an adjustable road and bridge expansion joint device.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: providing an adjustable road and bridge expansion joint device, including a cross beam plate and a side beam plate, a plurality of middle beam plates are fixedly connected to the top of the cross beam plate, the inner walls of the two side beam plates are provided with connecting grooves, and sealing belts are slidably connected between the two side beam plates and the inner walls of the middle beam plate, an adjustable dustproof component is installed between the two side beam plates, displacement control components are installed on both sides of the outer walls of the plurality of cross beam plates, a plurality of connecting plates are fixedly connected to the bottom of the two side beam plates, and a reinforcement ring is fixedly connected to the front end of the outer walls of the plurality of connecting plates.

[0007] The utility model is further configured such that outer walls of the two sealing belts are tightly fitted with inner walls of the corresponding connecting grooves, and the two sealing belts are made of rubber material.

[0008] Through the above technical solution, the rubber material has a certain elasticity and can adapt to different shape and size changes when it is tightly fitted with the inner wall of the connecting groove, effectively preventing gas, liquid and other media from leaking from the connection, thereby improving the sealing performance. At the same time, it can effectively isolate the connection part from the external environment, preventing dust, moisture, impurities, etc. from entering the connection, thereby protecting the components of the connection part from erosion and damage by external factors and extending the service life of the equipment.

[0009] The utility model is further configured as follows: the outer walls of the two side beam plates and the middle beam plate are both provided with connecting grooves, and are both located in the same plane.

[0010] Through the above technical solution, the connecting grooves on the same plane make it easier to operate when installing the sealing tape or assembling other connecting components. There is no need for complicated angle adjustments or position alignment. The installer can quickly and accurately install the sealing tape and other components into the connecting groove, thereby improving installation efficiency.

[0012] Through the above technical solution, the dustproof plate is first slidably connected to the inner wall of the hole, and then the two fixed holes are slidably connected to the two sides of the outer wall of the dustproof plate. At the same time, when the sealing belt expands and contracts due to heat and cold, multiple follower rods will move synchronously along the corresponding adjustment holes, thereby achieving the purpose of dust prevention.

[0013] The utility model is further configured as follows: the two fixing holes and the connecting hole are all in the same plane, and the dustproof plate passes through the center of the connecting hole, and the outer walls of the plurality of driven rods are tightly fitted with the inner walls of the corresponding adjustment holes.

[0014] Through the above technical solution, the fixing holes and the connecting holes are in the same plane, so that during installation and use, the forces acting on each component can be distributed more evenly, which helps to reduce local stress concentration, improve the stability and reliability of the entire structure, and reduce the risk of structural damage due to uneven force. At the same time, the close fit between the driven rod and the adjustment hole makes the adjustment process smoother and more precise, and when adjustment is required, the movement of the driven rod can be better controlled.

[0015] The present invention is further configured such that the bottoms of the outer walls of the plurality of limit plates are tightly fitted with the inner walls of the corresponding guide grooves.

[0016] Through the above technical solution, the tight fit ensures that the position of the limit plate in the guide groove is accurate, which enables the related components to be installed and operated according to the predetermined design position, thereby improving the assembly accuracy and operation reliability of the entire device.

[0017] The utility model is further configured as follows: the displacement control assembly includes a plurality of mounting boxes fixedly connected to the bottom of the two side beam plates, the bottom and top of the inner walls of the plurality of mounting boxes are fixedly connected with a first rubber pad and a second rubber pad, and the first rubber pad and the second rubber pad are tightly fitted with the outer wall of the corresponding cross beam plate.

[0018] Through the above technical solution, when the sealing belt expands and contracts due to thermal expansion and contraction, the sealing belt will drive the corresponding side beam plate to move left and right, and then the two side beam plates will drive the corresponding installation box to move. At the same time, the first rubber pad and the second rubber pad will be slightly deformed to achieve displacement.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model prevents dust and gravel from contacting the expansion joint device and the bridge structure by setting an adjustable dustproof component, reducing the wear and erosion of the bridge beam ends, abutments and other parts. This helps to extend the service life of the bridge structure, reduce the frequency of repairs and reinforcements, and reduce maintenance costs.

[0021] 2. By setting up a displacement control component, the utility model can improve the performance and reliability of the adjustable road and bridge expansion joint device, thereby ensuring the quality of the road and bridge project. A good expansion joint device can effectively adapt to the deformation of the bridge, reduce the damage and maintenance frequency of the bridge structure, and improve the service life and safety of the bridge.
