Description

Technical Field

[0001] The invention relates to the technical field of expansion joints, and in particular to an expansion joint connection assembly for bridge vibration reduction and noise reduction. Background Art

[0002] Bridge expansion joint: refers to the expansion joint usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge to meet the requirements of bridge deck deformation. The expansion joint is required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, and to be firm and reliable. When vehicles pass through, they should be smooth, without sudden jumps and noise; they should be able to prevent rainwater and garbage and soil from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt should be simple and convenient. At the expansion joint, the railing and the bridge deck pavement should be disconnected. The function of the bridge expansion joint is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge construction materials. Once the expansion device of the skew bridge is damaged, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents.

[0003] A bridge expansion joint with publication number CN116856271A. The bridge expansion joint includes: a first support, a second support, a first waterproof member, a mounting seat, a plurality of swing legs, a plurality of telescopic legs and a protective layer. There is a gap between the second support and the first support. The mounting seat is located in the gap. One end of each swing leg is rotatably connected to the mounting seat, and the other end of each swing leg is connected to the first support or the second support. One end of each telescopic leg is connected to the mounting seat, and the other end is connected to the first waterproof member. When a part of the first waterproof member is subjected to force, the force is redistributed through a plurality of telescopic legs, a plurality of swing legs and the mounting seat, and the force is transmitted to the first support and the second support. On the one hand, the bearing capacity of the first waterproof member is improved and the wear at the connection position between the first waterproof member and the first support and the second support is reduced. On the other hand, overload damage to the telescopic legs near the force-bearing position of the first waterproof member is avoided.

[0004] Although the expansion joint connection assembly in the above technical solution improves the bearing capacity of the waterproof assembly and avoids overload damage to the components, it still lacks further optimization of the shock absorbing function of the expansion joint, resulting in poor shock absorbing effect and unable to meet the shock absorbing requirements when the expansion joint undergoes multi-directional changes such as horizontal or vertical.

[0017] Technical effects and advantages of the present invention: 1. The present invention arranges a support assembly and a shock absorbing assembly between the embedded parts of the bridge, the support assembly and the shock absorbing assembly form an expansion joint connection assembly, and the expansion joint connection assembly is installed on the embedded parts of the bridge in an overlapping manner. The overlapping installation method can effectively ensure that the connection assembly directly transmits the pressure of the vehicle to the embedded parts of the bridge, thereby improving the bearing capacity of the connection assembly, and further ensuring the service life of the connection assembly. By arranging two groups of shock absorbing structures between the support assembly and the shock absorbing assembly, the design of the two groups of shock absorbing structures can effectively improve the shock absorbing and noise reduction capabilities of the connection assembly, and further improve the use effect of the device; 2. The present invention provides a support assembly and a shock absorbing assembly, wherein a support arm and a movable seat are provided between the support assembly and the shock absorbing assembly, a sliding column is provided between the support arm and the movable seat, and a buffer spring is provided on the outside of the sliding column. When the embedded bridge part changes due to external factors such as expansion, the sliding column slides on the outside of the movable seat, and the buffer spring can play a role of shock absorption and buffering. An adjusting screw is provided between the movable seat and the support assembly, and an adjusting nut is provided on the outside of the adjusting screw. By rotating the adjusting nut, the position of the movable seat can be adjusted, and then the spacing between the support assembly and the shock absorbing assembly can be adjusted. Then, the installation condition of the device can be adjusted according to the construction standard of the embedded bridge part, so as to facilitate the debugging of the device. 3. The present invention provides a support component and a shock-absorbing component, and a waterproof component is provided between the support component and the shock-absorbing component. The waterproof component is provided as a waterproof rubber strip with a "V"-shaped structure. Since two groups of support components and shock-absorbing components are provided, and a transition panel is also provided between the support component and the shock-absorbing component, the width of the waterproof component is much smaller than the width of the expansion joint between the two bridge embedded parts. When the bridge embedded parts expand and contract, the deformation amount of the waterproof component is small, thereby solving the problem that the service life of the waterproof component is affected by excessive deformation amount and too many times; 4. The present invention uses the first hydraulic chamber, the first oil guide ring and the one-way hydraulic rod in coordination, so that when the expansion joint moves longitudinally, the expansion joint connection assembly can not only absorb kinetic energy by causing deformation of the damping spring when the damping expansion rod rotates, but also absorb kinetic energy by causing deformation of the buffer spring by driving the slide seat to move through the one-way hydraulic rod, thereby absorbing the kinetic energy generated by the movement of the expansion joint from multiple parts and improving the effect of shock absorption and noise reduction; 5. The present invention uses the second hydraulic chamber, the bidirectional hydraulic rod and the second oil guide ring in coordination, so that when the expansion joint moves laterally, the expansion joint connection assembly can not only absorb kinetic energy by squeezing one end of the damping spring through the connection block and damping the change of the expansion joint itself, but also absorb kinetic energy by causing deformation of the other end of the damping spring by driving the driven frame to move through the bidirectional hydraulic rod, thereby absorbing the kinetic energy generated by the movement of the expansion joint from multiple directions, improving the kinetic energy absorption efficiency, and improving the shock absorption and noise reduction effect; 6. The present invention provides auxiliary components so that no matter the expansion joint moves in a single direction, such as horizontal or vertical, or moves in multiple directions, such as horizontal and vertical, the expansion joint connection component can quickly absorb the kinetic energy generated by the changes from multiple positions and directions, thereby effectively improving the kinetic energy absorption efficiency of the expansion joint connection component and ensuring its shock absorption and noise reduction effect.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0035] The present invention provides Figures 1 to 10A bridge shock-absorbing and noise-reducing expansion joint connection assembly shown in the figure includes a bridge embedded part 1, a support assembly 2, a shock-absorbing assembly 3, a waterproof assembly 4 and a transition panel 5. Two groups of shock-absorbing assemblies 3 are provided, and the two groups of shock-absorbing assemblies 3 are respectively provided on both sides of the support assembly 2. Two groups of waterproof assemblies 4 are provided, and the two groups of waterproof assemblies 4 are respectively provided between the shock-absorbing assemblies 3 and the support assembly 2. The transition panel 5 is provided above the support assembly 2. Two groups of bridge embedded parts 1 are provided, and the support assembly 2, the shock-absorbing assembly 3, the waterproof assembly 4 and the transition panel 5 are all provided between the two groups of bridge embedded parts 1. The transition panel 5 is flush with the upper surface of the bridge embedded parts 1.

[0036] The bridge embedded part 1 includes an embedded block 101, which is embedded at both ends of the bridge when the bridge is cast to facilitate the installation of the expansion joint assembly. An installation groove 102 is provided at one end of the embedded block 101. An extension groove 103 of a triangular structure is provided at the bottom end of the inner wall of one side of the installation groove 102. The bottom end of the fixed plate 301 is set as a triangular structure corresponding to the extension groove 103. The setting of the extension groove 103 can increase the contact area between the fixed plate 301 and the embedded block 101, so as to improve the installation stability of the device.

[0037] The support assembly 2 includes a support plate 201 , which is disposed between two embedded blocks 101 . Both ends of the support plate 201 are fixed with extension plates 202 by bolts, and the extension plates 202 correspond to the installation slots 102 .

[0038] Specifically, a fixing block 203 is fixedly disposed on the top of each of the extension plate 202 and the fixing plate 301 , and a fixing seat 204 with a “C”-shaped structure is fixedly disposed on the inner side of the fixing block 203 .

[0039] More specifically, a plurality of splicing blocks 205 are fixedly disposed on the upper surface of the fixed block 203 , and the splicing blocks 205 above two fixed blocks 203 are staggered.

[0040] In addition, a square groove 206 is provided through the middle of the extension plate 202 , an extension seat 207 is fixedly provided inside the square groove 206 , and a mounting hole 208 is provided through the middle of the extension seat 207 .

[0041] Moreover, a plurality of sliding columns 210 are fixedly arranged in the middle of the bottom end of the support plate 201, a plurality of sliding seats 211 are sleeved on the outer side of the sliding column 210, and a damping sleeve is arranged between the sliding seat 211 and the sliding column 210. The arrangement of the damping sleeve makes the sliding of the sliding seat 211 have a certain damping effect. When the support plate 201 and the fixed plate 301 move relative to each other due to the expansion and contraction of the bridge, the sliding seat 211 slides on the outer side of the sliding column 210. At this time, the damping sleeve cooperates with the buffer spring 212 to absorb kinetic energy and reduce shock. A buffer spring 212 is arranged between the sliding seat 211 and the support plate 201.

[0042] Meanwhile, connecting arms 213 are movably provided on both sides of the slide seat 211 through pin shafts, a connecting seat 214 is movably provided on one end of the connecting arm 213 through a pin shaft, and the connecting seat 214 is fixed to one end of the fixing plate 301 through bolts.

[0043] The shock absorbing assembly 3 includes a fixing plate 301 , and the fixing plate 301 is disposed inside the mounting groove 102 .

[0044] Specifically, a plurality of support rods 302 are fixedly provided at the inner bottom end of the fixed plate 301, a support arm 303 is movably provided at the middle part of the support rod 302 through a pin shaft, and two adjacent support arms 303 are symmetrically arranged, a movable seat 304 is arranged between the two adjacent support arms 303, and sliding holes opened on both sides of the movable seat 304 are provided with sliding rods 305, and a shock absorbing spring 306 is arranged around the outer side of the sliding rod 305, and a connecting block 307 is fixedly provided at one end of the sliding rod 305, and the connecting block 307 is movably arranged at one end of the support arm 303 through a pin shaft, a damping telescopic rod 308 is fixedly provided between the movable seat 304 and the fixed plate 301, and the damping telescopic rod 308 is connected to the fixed plate 301 by a pin shaft connection, and the angle between the damping telescopic rod 308 and the fixed plate 301 can be changed. When longitudinal displacement occurs between the support plate 201 and the fixed plate 301, the damping telescopic rod 308 can rotate around the pin shaft, thereby not interfering with the longitudinal displacement of the support plate 201 and the fixed plate 301. At the same time, when the damping telescopic rod 308 rotates around the pin shaft, the force it receives will be transmitted to the shock absorbing spring 306 on both sides of the corresponding movable seat 304. An adjusting screw 309 is fixedly provided on the outer side of the movable seat 304, and the adjusting screw 309 is penetrated through the interior of the mounting hole 208. An adjusting nut 310 is sleeved on one end of the adjusting screw 309, and the adjusting nut 310 is arranged on both sides of the notch of the mounting hole 208. The adjusting nut 310 cooperates with the adjusting screw 309 to adjust the position of the movable seat 304, thereby adjusting the position between the support assembly 2 and the shock absorbing assembly 3.

[0045] More specifically, a plurality of receiving grooves 209 are provided on the lower surface of the extension plate 202, a support block 311 is fixedly provided at one end of the upper surface of the fixed plate 301, and a plurality of receiving blocks 312 corresponding to the receiving grooves 209 are fixedly provided on the top of the support block 311. The receiving blocks 312 cooperate with the receiving grooves 209 to connect the support assembly 2 and the shock absorbing assembly 3, so as to realize the motion coordination between the support assembly 2 and the shock absorbing assembly 3. The notch length and width of the receiving groove 209 are both larger than the receiving block 312. Therefore, when the bridge expansion joint undergoes lateral and longitudinal changes, the receiving block 312 can move laterally and longitudinally in the receiving groove 209.

[0046] In addition, a plurality of mounting screw holes 313 are provided through the upper surface of the fixing plate 301 , and the mounting screw holes 313 can cooperate with expansion bolts to realize the installation of the shock absorbing assembly 3 .

[0047] The waterproof component 4 includes a waterproof rubber strip 401, and the cross-section of the waterproof rubber strip 401 is set to a "V" shape structure. The waterproof rubber strip 401 is set between the extension plate 202 and the fixed plate 301. The setting of the "V" shape structure allows the waterproof rubber strip 401 to deform toward the middle, thereby ensuring its waterproof effect.

[0048] Furthermore, installation strips 402 are fixedly provided at both ends of the waterproof strip 401 , and the installation strips 402 correspond to the fixing seat 204 . The installation strips 402 can be inserted into the fixing seat 204 to achieve the installation of the waterproof strip 401 .

[0049] To sum up, when installing the device, first install the support component 2 at one end of the bridge embedded part 1, then splice the shock-absorbing component 3 with the support component 2, and install the waterproof component 4 between the support component 2 and the shock-absorbing component 3, and finally install the transition panel 5 on top of the support component 2 to complete the installation of the device.

[0050] During the installation of the device, firstly, one end of the bridge embedded part 1 is processed, and the installation groove 102 and the extension groove 103 are opened, and then the fixing plate 301 is fixedly installed in the installation groove 102 through the installation screw hole 313 and the expansion bolt, and then the support plate 201 is placed between the two fixing plates 301, and the multiple receiving blocks 312 are all located in the corresponding receiving grooves 209, and the adjusting screw 309 is passed through the installation hole 208, and then the adjusting nut 310 is sleeved on the adjusting screw 309, and then the adjusting nut 310 is rotated. The adjusting nut 310 cooperates with the adjusting screw 309 to adjust the distance between the movable seat 304 and the extension plate 202, and then the distance between the support assembly 2 and the shock absorbing assembly 3 can be adjusted. The multiple adjusting nuts 310 are adjusted in sequence to achieve the installation of the support plate 201.

[0051] After the support plate 201 is installed, the connecting seat 214 is installed on one side of the support block 311 by bolts to complete the installation of the support assembly 2. Finally, the transition panel 5 is glued or installed on the top of the support plate 201 by bolts to complete the installation of the device.

[0052] During the use of the device, when the expansion joint of the bridge body moves laterally due to its own expansion or other factors, the fixed plate 301 and the extension plate 202 will move relative to each other in the horizontal direction, that is, the receiving block 312 will move laterally in the corresponding receiving groove 209, and the distance between the fixed plate 301 and the extension plate 202 will become smaller. At this time, the fixed plate 301 drives the support arm 303 to move through the support rod 302, and the support arm 303 drives the connecting block 307 to move through the pin shaft, and the connecting block 307 drives the sliding rod 305 to move, and the movement of the sliding rod 305 compresses the shock absorbing spring 306, and at the same time When the damping telescopic rod 308 between the movable seat 304 and the fixed plate 301 is compressed, the shock-absorbing spring 306 and the damping telescopic rod 308 can absorb kinetic energy. During this process, the distance between the two fixed plates 301 becomes smaller, and the fixed plate 301 drives the connecting arm 213 to move through the connecting seat 214, and the connecting arm 213 drives the sliding seat 211 to move, so that the sliding seat 211 slides on the outside of the sliding column 210, causing the buffer spring 212 to deform, thereby absorbing kinetic energy, and further achieving the effect of shock absorption and noise reduction during the lateral movement of the expansion joint.

[0053] When the expansion joint of the bridge body moves longitudinally due to factors such as wind, the fixed plate 301 and the extension plate 202 will move relative to each other in the longitudinal direction, that is, the receiving block 312 will move longitudinally in the corresponding receiving groove 209. At this time, the damping telescopic rod 308 will rotate around the pin shaft and transmit the force it receives to the shock-absorbing spring 306 on both sides of the corresponding movable seat 304, so that the shock-absorbing spring 306 is deformed, thereby absorbing the kinetic energy, and further achieving the effect of shock absorption and noise reduction during the longitudinal movement of the expansion joint. Example

[0054] In the above embodiment, the connecting block 307 drives the slide bar 305 to move so that one end of the shock absorbing spring 306 is compressed. At the same time, the damping telescopic rod 308 itself is compressed and the slide seat 211 slides on the outer side of the slide column 210 to deform the buffer spring 212, so as to achieve the effect of shock absorption and noise reduction during the lateral movement of the expansion joint; the damping telescopic rod 308 rotates around the pin shaft and transmits the force it receives to the shock absorbing springs 306 on both sides of the corresponding movable seat 304, so that the shock absorbing springs 306 are deformed, so as to achieve the effect of shock absorption and noise reduction during the longitudinal movement of the expansion joint. However, the method and path of absorbing the kinetic energy generated by the longitudinal movement of the expansion joint by relying solely on the deformation of the shock absorbing spring 306 are relatively simple, and when the expansion joint simultaneously moves in multiple directions such as lateral and longitudinal directions, it is not conducive to improving the efficiency of the expansion joint connection assembly in absorbing kinetic energy, and its shock absorption and noise reduction effect cannot be guaranteed. Therefore, the above scheme is further improved so that no matter what kind of movement occurs in the expansion joint, the expansion joint connection assembly can quickly absorb the kinetic energy generated by the change from multiple locations and directions, effectively improving the kinetic energy absorption efficiency of the expansion joint connection assembly and ensuring its shock absorption and noise reduction effect.

[0055] Specifically, Figure 11-15 As shown, an auxiliary component 6 is provided between the supporting component 2 and the shock absorbing component 3 , and the number and position of the auxiliary components 6 correspond to the sliding seat 211 and the movable seat 304 .

[0056] The auxiliary component 6 includes a first hydraulic chamber 601 and a second hydraulic chamber 602. There are multiple first hydraulic chambers 601 and second hydraulic chambers 602, and hydraulic fluid is arranged inside them. The multiple first hydraulic chambers 601 are symmetrically fixed on both sides of the corresponding receiving groove 209, and the multiple second hydraulic chambers 602 are fixed on one side of the corresponding receiving groove 209. Piston plates 603 are slidably arranged inside the first hydraulic chamber 601 and the second hydraulic chamber 602. The interiors of the first hydraulic chamber 601 and the second hydraulic chamber 602 are sealed with the piston plate 603, and one side of the piston plate 603 is fixedly connected with a piston rod 604 that passes through the outside, and one end of the piston rod 604 is fixedly provided with an extrusion plate 605.

[0057] More specifically, a first oil guide ring 606 is arranged above the slide 211, and the first oil guide ring 606 is fixedly arranged at the bottom of the support plate 201. The bottom of the first oil guide ring 606 is connected to and fixedly provided with a one-way hydraulic rod 607, and the movable end of the one-way hydraulic rod 607 is fixedly connected to the top of the slide 211. Multiple first hydraulic chambers 601 are connected to the corresponding first oil guide rings 606 through oil guide pipes.

[0058] At the same time, driven frames 608 are slidably arranged on both sides of the movable seat 304, and the driven frames 608 and one end of the shock-absorbing spring 306 on the corresponding side are abutted against each other, and two-way hydraulic rods 609 are fixedly arranged on both upper and lower ends of the movable seat 304, and the two movable ends of the two-way hydraulic rod 609 are respectively fixedly connected to the driven frames 608 on the same side, and a second oil guide ring 610 is arranged on one side of the movable seat 304, and the second oil guide ring 610 is connected to the corresponding two two-way hydraulic rods 609, and multiple second hydraulic chambers 602 are connected to the corresponding second oil guide rings 610 through oil guide pipes.

[0059] It should be noted that the driven frame 608 is slidably sleeved on the outside of the corresponding movable seat 304, that is, the driven frame 608 is sleeved on the outside of the corresponding side sliding rod 305. The driven frame 608 can slide along the corresponding side sliding rod 305 under the push of the bidirectional hydraulic rod 609 and squeeze the shock-absorbing spring 306 on the same side at the same time.

[0060] Furthermore, the one-way hydraulic rod 607 can drive the slide seat 211 to move downward under the pressure of the hydraulic fluid in the first oil guide ring 606 , thereby causing the buffer spring 212 to deform.

[0061] Based on the above embodiment, by further optimizing the above related components, when the expansion joint moves laterally due to the expansion of the bridge body and other factors, on the basis of the above-mentioned damping of the lateral movement of the expansion joint, as the spacing between the fixed plate 301 and the extension plate 202 becomes smaller, the receiving block 312 will move laterally in the corresponding receiving groove 209, and the receiving block 312 will gradually contact and push the extrusion plate 605, so that the extrusion plate 605 pushes the piston plate 603 to move in the second hydraulic chamber 602 through the piston rod 604. In this process, the hydraulic pressure in the second hydraulic chamber 602 Under the squeezing action of the piston plate 603, the fluid will enter the second oil guide ring 610 through the oil guide pipe, and enter the two-way hydraulic rod 609 through the second oil guide ring 610, so that both ends of the two-way hydraulic rod 609 extend at the same time. At this time, the two-way hydraulic rod 609 will push the driven frames 608 on both sides to move, and in the process of the two driven frames 608 moving in opposite directions, multiple shock-absorbing springs 306 will buffer the two driven frames 608, thereby absorbing the kinetic energy of the driven frames 608, that is, absorbing the kinetic energy generated when the expansion joint moves horizontally.

[0062] When the expansion joint of the bridge body moves longitudinally due to factors such as wind force, on the basis of the above-mentioned shock absorption of the longitudinal movement of the expansion joint, as the fixed plate 301 and the extension plate 202 will move relative to each other in the longitudinal direction, that is, the receiving block 312 will move longitudinally in the corresponding receiving groove 209, the receiving block 312 will gradually contact and push the extrusion plate 605, so that the extrusion plate 605 drives the piston plate 603 to move in the first hydraulic chamber 601 through the piston rod 604. During this process, the hydraulic fluid in the first hydraulic chamber 601 will enter the first oil guide ring 606 through the oil guide pipe, and enter the one-way hydraulic rod 607 through the first oil guide ring 606, so that the movable end of the one-way hydraulic rod 607 is extended. At this time, the movable end of the one-way hydraulic rod 607 will drive the slide 211 to move downward along the slide column 210, so that the slide 211 drives the buffer spring 212 to deform, thereby realizing the absorption of kinetic energy, that is, realizing the absorption of the kinetic energy generated when the expansion joint moves longitudinally.

[0063] Therefore, through the coordinated use of the first hydraulic chamber 601, the first oil guide ring 606 and the one-way hydraulic rod 607, when the expansion joint undergoes longitudinal movement, the expansion joint connection assembly can not only absorb kinetic energy by causing deformation of the shock-absorbing spring 306 when the damping expansion rod 308 rotates, but also absorb kinetic energy by causing deformation of the buffer spring 212 by driving the slide 211 to move through the one-way hydraulic rod 607, thereby achieving the absorption of the kinetic energy generated by the expansion joint movement from multiple parts and improving the shock-absorbing and noise-reducing effects.

[0064] Through the coordinated use of the second hydraulic chamber 602, the two-way hydraulic rod 609 and the second oil guide ring 610, when the expansion joint moves laterally, the expansion joint connection assembly can not only absorb kinetic energy by squeezing one end of the shock-absorbing spring 306 by the connecting block 307 and the change of the damping expansion rod 308 itself, but also absorb kinetic energy by causing deformation of the other end of the shock-absorbing spring 306 by driving the driven frame 608 to move by the two-way hydraulic rod 609, thereby absorbing the kinetic energy generated by the expansion joint movement from multiple directions, improving the kinetic energy absorption efficiency, and improving the shock absorption and noise reduction effects.

[0065] In summary, through the optimization and improvement of the above technical solution, that is, by setting the auxiliary component 6, no matter the expansion joint undergoes unidirectional movement such as horizontal or vertical movement alone, or multi-directional movement such as horizontal and vertical movement simultaneously, the expansion joint connection component can quickly absorb the kinetic energy generated by the changes from multiple positions and directions, effectively improving the kinetic energy absorption efficiency of the expansion joint connection component and ensuring its shock absorption and noise reduction effect.
