Description

Technical Field

[0001] This utility model belongs to the field of road and bridge construction technology, specifically a telescopic connection structure for roads and bridges. Background Technology

[0002] In road and bridge construction, expansion and contraction deformation are inevitable due to various factors such as temperature changes and vehicle loads. If the expansion joint structure is not designed properly, it can easily lead to road surface cracks, misalignments, and other defects. This not only seriously affects driving comfort and safety but also significantly increases subsequent maintenance costs. However, some existing expansion joint structures have significant shortcomings in terms of deformation adaptability and durability, making it difficult to meet the ever-increasing traffic demands. Utility Model Content

[0003] To address the problems existing in the background art, this utility model provides a telescopic connection structure for roads and bridges.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic connection structure for roads and bridges, comprising a rubber strip, a first sealing strip, two second sealing strips, two telescopic mechanisms, multiple rubber balls, and multiple buffer mechanisms;

[0005] A rubber strip is provided between the two telescopic mechanisms. The rubber strip has a diamond-shaped hole. Multiple rubber balls are evenly distributed along the length of the upper and lower ends of the rubber strip. The multiple rubber balls located at the upper end of the rubber strip are tightly fitted to the corresponding telescopic mechanisms on both sides. Multiple buffer mechanisms are evenly distributed along the length of the two telescopic mechanisms at their far ends. The two telescopic mechanisms are symmetrically arranged. A sealing strip I is provided between the two telescopic mechanisms. A sealing strip II is provided at the far ends of the two telescopic mechanisms. Both sealing strip I and sealing strip II are provided with water guide grooves.

[0006] Each of the telescopic mechanisms includes a base plate, a rectangular block, multiple anchor rods, and multiple anchor bars;

[0007] Multiple anchor rods are evenly distributed along the length of the lower end face of the base plate. The upper end face of the base plate is fixedly connected to a horizontally arranged rectangular block. Multiple sliding grooves are evenly distributed along the length of one side of the rectangular block. Each sliding groove is equipped with a buffer mechanism. Multiple anchor bars are provided below the multiple buffer mechanisms. The lower ends of the multiple anchor bars are fixedly connected to the base plate. One side of the multiple anchor bars is fixedly connected to the rectangular block. The other side of the rectangular block is equipped with a placement groove that matches the rubber strip. One end of the rubber strip is placed in the placement groove.

[0008] Each of the aforementioned buffer mechanisms includes a slide bar, a top block, a fixing post, and a spring;

[0009] The slide rod is slidably set in the corresponding slide groove. One end of the slide rod is fixedly connected to the top block, and the other end of the slide rod is fixedly connected to the fixed column. A spring is fitted on the fixed column. One end of the spring is fixedly connected to the slide rod, and the other end of the spring is tightly fitted to the inner wall of the slide groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Enhanced elasticity and durability: A rubber strip with diamond-shaped holes is provided between the two telescopic mechanisms. The diamond structure can deform flexibly when subjected to force, dispersing stress during repeated expansion and contraction, increasing the elasticity of the rubber strip and improving its durability.

[0012] 2. Improved tightness and cushioning sealing: Multiple rubber balls are evenly distributed on both ends of the rubber strip, which enhances the tightness of the fit between the rubber strip and the telescopic mechanism and the groove, while also providing cushioning and sealing.

[0013] 3. Ensuring structural stability: The buffer mechanism installed on each expansion joint allows the rubber strips and rubber balls to elastically deform and relieve stress when the road or bridge expands or contracts due to factors such as temperature and load. The slide bar of the buffer mechanism slides in the groove, and the elastic deformation of the spring offsets the impact, improving the overall stability and durability of the expansion joint structure and reducing the impact of deformation on the road or bridge itself.

[0014] 4. Ensure sealing and extend service life: The telescopic connection structure is equipped with sealing strip one and sealing strip two respectively. The sealing design ensures airtightness and effectively prevents water, dust and other debris from entering the interior. The sealing strip is equipped with water guide grooves to smoothly drain rainwater, avoid water accumulation damage and extend the service life of the structure.

[0015] In summary, this utility model, through its unique design of diamond-shaped holes in the rubber strip, the setting of the rubber ball, the equipment of the buffer mechanism, and the double sealing structure, significantly enhances the elasticity, durability, tightness of fit, and buffer sealing performance of the structure. It effectively ensures the stability of the structure during the expansion and contraction deformation of roads or bridges, while ensuring good sealing performance, preventing the entry of debris and water accumulation damage, and greatly extending the service life of the structure. It has significant beneficial effects and practical application value. Attached Figure Description

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0018] This embodiment describes a telescopic connection structure for roads and bridges, including a rubber strip 9, a sealing strip 11, two sealing strips 12, two telescopic mechanisms, multiple rubber balls 10, and multiple buffer mechanisms.

[0019] A rubber strip 9 is provided between the two telescopic mechanisms. The rubber strip 9 has a diamond-shaped hole. Multiple rubber balls 10 are evenly distributed along the length direction on the upper and lower ends of the rubber strip 9. The multiple rubber balls 10 located at the upper end of the rubber strip 9 are tightly fitted to the corresponding telescopic mechanisms on both sides. Multiple buffer mechanisms are evenly distributed along the length direction at the far ends of the two telescopic mechanisms. The two telescopic mechanisms are symmetrically arranged. A sealing strip 11 is provided between the two telescopic mechanisms. A sealing strip 2 12 is provided at the far ends of the two telescopic mechanisms. Water guide grooves are provided on both the sealing strip 11 and the sealing strip 2 12.

[0020] Each of the telescopic mechanisms includes a base plate 1, a rectangular block 3, multiple anchor rods 2, and multiple anchor bars 4;

[0021] Multiple anchor rods 2 are evenly distributed along the length of the lower end face of the base plate 1. The upper end face of the base plate 1 is fixedly connected to a horizontally arranged rectangular block 3. Multiple sliding grooves are evenly distributed along the length of one side of the rectangular block 3. Each sliding groove is equipped with a buffer mechanism. Multiple anchor bars 4 are provided below the multiple buffer mechanisms. The lower ends of the multiple anchor bars 4 are fixedly connected to the base plate 1. One side of the multiple anchor bars 4 is fixedly connected to the rectangular block 3. The other side of the rectangular block 3 is equipped with a placement groove that matches the rubber strip 9. One end of the rubber strip 9 is placed in the placement groove.

[0022] Each of the aforementioned buffer mechanisms includes a slide bar 5, a top block 6, a fixing post 7, and a spring 8;

[0023] The slide rod 5 is slidably disposed in the corresponding slide groove. One end of the slide rod 5 is fixedly connected to the top block 6, and the other end of the slide rod 5 is fixedly connected to the fixing column 7. A spring 8 is fitted on the fixing column 7. One end of the spring 8 is fixedly connected to the slide rod 5, and the other end of the spring 8 is tightly fitted to the inner wall of the slide groove.

[0024] When using this utility model, firstly, the two telescopic mechanisms are fixed in the groove of the road or bridge by the anchor rods 2 at their lower ends to ensure that the telescopic mechanisms are stable and immobile. A rubber strip 9 is provided between the telescopic mechanisms, and the rubber strip 9 has diamond-shaped holes. The diamond structure can deform more flexibly under force, dispersing stress during repeated expansion and contraction. This not only increases the elasticity of the rubber strip but also improves its durability. Multiple rubber balls 10 are evenly distributed along the length of the upper and lower end faces of the rubber strip 9. These rubber balls 10 not only enhance the tightness of the fit between the rubber strip 9 and the telescopic mechanism and the groove, but also play a certain role in buffering and sealing. In addition to the buffering effect of the rubber strip and rubber balls, a special buffering mechanism is also provided on the telescopic mechanism to further ensure structural stability. Multiple buffering mechanisms are evenly distributed along the length of the two telescopic mechanisms at their far ends. When the road or bridge expands or contracts due to factors such as temperature and load, the rubber strip 9 and... The rubber ball 10 can undergo elastic deformation to alleviate the stress generated by deformation. At the same time, the slide bar 5 of the buffer mechanism can slide in the corresponding groove, and the spring 8 will also undergo elastic deformation to offset the impact of expansion and contraction. This design not only improves the overall stability and durability of the expansion connection structure, but also effectively reduces the impact of deformation on the road or bridge itself. At both ends of the expansion connection structure, sealing strip 11 and sealing strip 2 12 are respectively set. Sealing strip 11 is used to seal the gap between the two expansion mechanisms, and sealing strip 2 12 is used to seal the gap between the expansion mechanism and the inner wall of the groove. This double sealing design ensures the airtightness of the expansion connection structure, effectively preventing water, dust and other debris from entering the interior, thereby extending the service life of the structure. In addition, both sealing strip 11 and sealing strip 2 12 are equipped with water guide grooves to smoothly drain rainwater and prevent water accumulation from damaging the expansion connection structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention.
