[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] The following is combined Figures 1-8 In describing the bridge expansion joint device of the present invention, it should be noted that the above-mentioned bridge expansion joint device can be applied not only between the ends of two beams, between the beam end and the abutment, or at the hinged position of the bridge, but also at the connection points of both ends of a road. In some embodiments of the present invention, the bridge expansion joint device of the present invention is installed at the connection point of the bridge and is installed in conjunction with the bridge body.

[0043] like Figures 1 to 5 as well as Figure 7As shown, the bridge expansion joint device according to the present invention includes: two sets of beam units 10, which are arranged facing each other and can move towards or away from each other. Each beam unit 10 includes a beam assembly 11 and a pressure-bearing seat 12 for bearing pressure. The pressure-bearing seat 12 is movably disposed on the beam assembly 11, and the two sets of pressure-bearing seats 12 are located between the two sets of beam assemblies 11, and the pressure-bearing seats 12 can move towards or away from the beam assembly 11; and a connecting unit 20, which is disposed between the two sets of beam units 10. The ends are respectively connected to two sets of beam units 10, and the two ends of the connecting unit 20 can move with the two sets of beam units 10 to be close to each other or away from each other; in the same set of beam units 10, multiple damping components 30 are provided between the beam assembly 11 and the bearing seat 12, and the multiple damping components 30 can move relative to the beam assembly 11 to buffer the force transmitted from the bearing seat 12 to the beam assembly 11; wherein, a linkage rod 40 is provided between any two adjacent damping components 30, and the linkage rod 40 is used to link the multiple damping components 30 together.

[0044] The bridge expansion joint device provided by this invention, by setting the present invention at the connection of the bridge, allows the shock-absorbing components 30 to play a buffering role when a vehicle passes over the bearing seat 12. Moreover, multiple shock-absorbing components 30 are beneficial to damping the relative movement between the bearing seat 12 and the beam assembly 11 in all directions, reducing the direct pressure of the vehicle on the bridge expansion joint device, and has high durability, good stability and reliability. In addition, by setting the linkage rod 40, the linkage rod 40 simultaneously links and cooperates multiple shock-absorbing components 30, increasing the integrity, stability and structural strength of the bridge expansion joint device.

[0045] It is understandable that, such as Figure 3 As shown, in some embodiments of the present invention, the top surface of the bearing seat 12 is positioned higher than the top surface of the beam assembly 11. Using this structure, the damping assembly 30 can be used to buffer the bridge expansion joint device, increasing its durability and reliability.

[0046] like Figures 1 to 6 As shown, in some embodiments of the present invention, the shock-absorbing component 30 includes: an elastic member 31, one end of which is connected to the beam assembly 11; and a support member 32, one end of which is connected to the pressure seat 12, and the other end of which is connected to the other end of the elastic member 31. The support member 32 can move relative to the beam assembly 11 along with the pressure seat 12. The support members 32 of multiple shock-absorbing components 30 are all connected to the linkage rod 40. With the above structure, during use, when the pressure seat 12 vibrates due to external factors such as vehicle pressure, the pressure seat 12 displaces towards the shock-absorbing component 30, pushing the support member 32. The support member 32 then compresses the elastic member 31, causing the elastic member 31 to contract. The elasticity of the elastic member 31 itself then provides shock absorption.

[0047] It is understood that the aforementioned linkage rod 40 can be set to one, with one linkage rod 40 passing through all the support members 32; in some embodiments, the number of linkage rods 40 is set to multiple, with one linkage rod installed between any two adjacent support members 32, which still has the above-mentioned effect, and is not limited here.

[0048] Specifically, such as Figures 1 to 6 As shown, in some embodiments of the present invention, the support member 32 is slidably connected to the beam assembly 11, the beam assembly 11 is provided with a sliding channel 51, and the support member 32 is provided with a sliding part 52 that slides and engages with the sliding channel 51. Using the above structure, the sliding engagement of the sliding part 52 and the sliding channel 51 improves the installation stability of the support member 32 and the elastic member 31, making both the support member 32 and the elastic member 31 more reliable and compact when moving with the bearing seat 12.

[0049] Of course, in some embodiments, the sliding part 52 may also be provided on the beam assembly 11, and the sliding channel 51 may be provided on the support member 32, which is not limited here.

[0050] It should be noted that the elastic element 31 is a cylindrical shock-absorbing spring. Of course, in some embodiments, the elastic element 31 can also be set as an elastic pad, elastic plate, etc. The bearing seat 12 moves up and down relative to the beam assembly 11 and can drive the support 32 to move and the elastic element 31 to elastically reset. The support 32 is provided with an installation recess that cooperates with the bearing seat 12, and the longitudinal section of the support 32 is L-shaped.

[0051] It is understood that in some embodiments of the present invention, along the vertical direction of the beam assembly 11, the length of the sliding channel 51 is greater than the length of the shock absorber, the height of the bottom surface of the sliding channel 51 is higher than the height of the bottom surface of the shock absorber, and the sliding part 52 moves relative to the sliding channel 51 to match the displacement caused by the elastic deformation of the shock absorber, thereby maximizing the range of movement of the slider and adapting to the vertical movement of the shock absorber.

[0052] It should also be noted that, such as Figure 6As shown, in some embodiments of the present invention, the sliding part 52 includes a sliding section and a limiting section. One end of the sliding section is integrally formed with the limiting section. The width of the sliding section is adapted to the inner diameter of the sliding channel 51, and the width of the limiting section is greater than the inner diameter of the sliding channel 51. During installation, the support member 32 corresponds to the sliding channel 51, the sliding section passes through the sliding channel 51, and the other end of the sliding section is fixedly connected to the support member 32 by bolts or other fasteners or welding. Alternatively, in some embodiments, the sliding section and the limiting section are separate structures, with the sliding section integrally formed with the support member 32, or the sliding section and the support member 32 are fixedly connected by bolts or other fasteners or welding, and the limiting section is fixedly connected to the sliding section by bolts or other fasteners or welding. With the above structure, the sliding section moves up and down along the sliding channel 51, and the limiting section restricts the relative position of the support member 32 and the beam assembly 11, preventing displacement and providing good stability. It is understood that the sliding part 52 is a T-shaped structure.

[0053] It is conceivable that in some embodiments of the present invention, the elastic member 31 is fixedly connected to the beam assembly 11 by fasteners such as bolts or welding; the support member 32 and the elastic member 31 are fixedly connected by fasteners such as bolts or welding; and the support member 32 and the bearing seat 12 are fixedly connected by fasteners such as bolts or welding.

[0054] like Figures 1 to 5 As shown, in some embodiments of the present invention, the beam assembly 11 includes: a beam 111; a first support plate 112 connected to the bottom of the beam 111, with an upper portion extending to one side of the beam 111 to form an installation area, a damping component 30 located in the installation area, and a bearing seat 12 correspondingly arranged to the installation area; a second support plate 113 located below the first support plate 112; and a pad 114 disposed between the first support plate 112 and the second support plate 113, with its upper and lower sides respectively connected to the first support plate 112 and the second support plate 113; wherein, the two ends of the connecting unit 20 are respectively connected to the first support plate 112 in the two sets of beam units 10. Using the above structure improves the structural strength and stability of the beam assembly 11, and the structure is reasonable and easy to manufacture.

[0055] It should be noted that the sum of the length of the damping spring, the distance between the upper and lower ends of the support member 32, and the thickness of the bearing seat 12 is greater than the thickness of the beam 111, and the top surface height of the bearing seat 12 is higher than the top surface height of the beam 111.

[0056] Specifically, such as Figures 1 to 5As shown, in some embodiments of the present invention, a plurality of first anchor rods 115 are provided on one side of the beam 111, and a plurality of second anchor rods 116 are provided at the bottom of the second support plate 113. The axes of the first anchor rods 115 and the axes of the second anchor rods 116 are perpendicular to each other. With the above structure, the first anchor rods 115 and the second anchor rods 116 can be used to strengthen the connection between the bridge expansion joint device and the installation location. The installation location can be, for example, between the ends of two beams, between the beam end and the abutment, or at the hinge point of the bridge; or at the roadbed, etc.

[0057] It is understandable that, such as Figures 1 to 5 As shown, in some embodiments of the present invention, the width of the first support plate 112 and the width of the second support plate 113 are both greater than the width of the pad 114, so that one side of the first support plate 112, one side of the pad 114 and one side of the second support plate 113 cooperate to form a groove, which further improves the reliability and firmness of the bridge expansion joint device installed at the installation position. For example, during installation, concrete is filled into the groove to improve installation stability.

[0058] Specifically, such as Figures 1 to 5 As shown, in some embodiments of the present invention, the connecting unit 20 is a deformable flexible component, the length of which is adapted to the length of the bearing seat 12. A drainage channel 21 is provided on the flexible component to drain liquid flowing into the two sets of beam units 10. The drainage channel 21 of the flexible component is arranged at an angle relative to the first support plate 112. Using the above structure, the drainage channel 21 of the flexible component guides and drains rainwater flowing into the bridge expansion joint device, preventing rainwater from corroding the device and the bridge deck. The angled arrangement of the drainage channel 21 of the flexible component further improves the drainage effect.

[0059] In some embodiments of the present invention, the bottom surface of the pad 114 is lower than the bottom surface of the flexible component. This structure prevents the bottom of the flexible component from being affected, thereby avoiding impact on the drainage effect of the drainage channel 21.

[0060] It should be noted that in some embodiments of the present invention, the above-mentioned flexible component is made of rubber. Of course, in some embodiments, the flexible component may also be made of other flexible elastomer materials, which are not limited here. The longitudinal cross-section of the above-mentioned flexible component is arc-shaped, that is, the flexible component is a U-shaped structure. The two ends of the flexible component are respectively fixed to the first support plate 112 by welding or snap-fitting.

[0061] It is understandable that, such as Figures 1 to 3 as well as Figure 7 and Figure 8As shown, in some embodiments of the present invention, the pressure-bearing seat 12 includes a seat body 121 and a plurality of locking blocks 122 spaced apart on one side of the seat body 121. The bottom surface of the seat body 121 is connected to the shock-absorbing component 30. The plurality of locking blocks 122 of the pressure-bearing seat 12 of one set of beam units 10 and the plurality of locking blocks 122 of the pressure-bearing seat 12 of another set of beam units 10 are arranged alternately. This structure allows the two sets of beam units 10 to move towards each other or away from each other, resulting in a reasonable structure and ingenious design. In use, rainwater and other liquids can flow through the gaps between adjacent locking blocks 122 into the drainage groove 21 of the flexible component, thereby being guided out.

[0062] It should be noted that the width of the aforementioned flexible component is greater than the distance between the end of the card block 122 that is connected to the seat 121 and the other end that is away from the seat 121, so that when the multiple card blocks 122 of the bearing seats 12 of the two sets of beam units 10 are arranged in an alternating manner after installation, the flexible component can fully drain the area where the card blocks 122 on both sides cooperate.

[0063] In some embodiments of the present invention, the length of the beam 111, the first support plate 112, the pad 114 and the second support plate 113 are equal, and the length of the flexible member is equal to the length of the first support plate 112, so as to further guide and discharge the rainwater flowing into the bridge expansion joint device, and prevent the rainwater from corroding the device and the bridge deck.

[0064] In some embodiments of the present invention, during installation, the beam 111 of the two sets of beam units 10, a portion of the first support plate 112, the pad plate 114, and the second support plate 113 are embedded in the bridge, at which time the first anchor rod 115 and the second anchor rod 116 play a fixing role.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
