Description

Technical Field

[0001] The present invention relates to the technical field of bridges, and more particularly to an assembly structure of a continuous rigid frame bridge and a construction method thereof. Background Art

[0002] With the rapid development of my country's highway industry, the construction of long-span continuous rigid frame bridges has increased significantly, especially in western my country. Continuous beam bridges are a type of bridge with large spans and excellent economic performance, and are currently widely used in various types of bridges.

[0003] During the actual construction of this continuous rigid frame bridge, the piers are first erected, and the bridge body is prefabricated at the top of the piers. A variable curvature bridge body steel cage is bundled using prefabricated steel bars, and then formwork is carried out. After the formwork is completed, concrete is poured until the bridge body is formed. During the construction of the bridge body, construction is carried out simultaneously in two directions at the top of the piers to ensure the weight balance at both ends of the piers. In addition, the prefabrication of the bridge body is also carried out in an intermittent manner, that is, the bridge body is poured in sections by means of formwork until the bridge body between the two piers is closed. Therefore, during the actual construction process, the construction of the bridge body and the piers is a continuous whole, and the bridge body between the two piers is closed to form a whole.

[0004] In actual use, continuous rigid frame bridges have a variable cross-section, with the smallest cross-section occurring at the point where the bridge is joined. As the bridge ages, stresses concentrate at this junction, making cracks more likely to form. This significantly impacts the overall maintenance and service life of the bridge. In existing technology, when cracks appear, regular maintenance is typically performed, using foam filling or other connecting components to eliminate them.

[0005] Chinese patent publication number CN112127268B discloses a bridge shock-absorbing device comprising a pier and a bridge deck connected to the top of the pier via a bridge. The bridge is a Y-shaped concrete structure, and a first shock-absorbing mechanism is symmetrically arranged on the top of the bridge. The first shock-absorbing mechanism comprises a top frame fixedly connected to the top of the bridge, and a recessed frame located outside the top of the top frame. A support platform is provided in the middle of the top frame, and a first spring is fixedly connected between the upper side of the support platform and the inner wall of the bottom of the recessed frame. The inner wall of the top of the recessed frame is provided with a buffer groove, and the top of the top frame is inserted into the buffer groove. This invention effectively reduces the longitudinal vibration of the bridge deck through the first spring. At the same time, the bridge deck can be connected to the support recess by rubber bearings, and the relative sliding of the first steel plate and the polytetrafluoroethylene plate effectively reduces the vibration of the bridge deck in the horizontal direction. This facilitates the rapid reset of the bridge deck and can also buffer the longitudinal pressure on the bridge deck, thereby achieving both longitudinal and horizontal vibration reduction.

[0006] The aforementioned solutions focus on overall bridge vibration reduction, but fail to address specific bridge joints where stress is concentrated and cracks are more likely to form. Therefore, for continuous rigid frame bridges, extending their service life and reducing maintenance costs are pressing challenges. Summary of the Invention

[0045] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance.

At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0047] The present invention relates to an assembly structure of a continuous rigid frame bridge, comprising a first assembly body and a second assembly body arranged at the connection between two groups of bridge bodies, a first buffer mechanism being arranged between the connection between the first assembly body and one group of bridge bodies, and the second assembly body being connected to the other group of bridge bodies, and a second buffer mechanism being arranged at the connection position between the first assembly body and the second assembly body.

[0048] A first buffer mechanism is installed between the first assembly and the connection between one of the bridge sections to prevent cracks from forming at the junction between the first assembly and the bridge section over time. A second buffer mechanism is installed between the first assembly and the second assembly to prevent cracks from forming at the junction between the two bridge sections over time. This assembly structure effectively connects the bridge sections and absorbs vibrations at these junctions, preventing stress concentration at the bridge sections. This increases the service life of the continuous rigid frame bridge and reduces maintenance costs for this type of bridge.

[0049] like Figure 1 As shown, the assembly structure of a continuous rigid frame bridge of this embodiment includes a first assembly body 200 and a second assembly body 300 arranged at the connection between adjacent bridge bodies 100, the first assembly body 200 is abutted against the bridge body 100, and the second assembly body 300 is rollingly and slidingly fitted with the bridge body 100; a first buffer mechanism is provided between the first assembly body 200 and the bridge body 100, and a second buffer mechanism is provided between the first assembly body 200 and the second assembly body 300.

[0050] About the first assembly:

[0051] To connect the first assembly 200 to the bridge body 100, the first assembly 200 and the transition connector 210 are plug-in or detachably matched. The transition connector 210 is connected to the bridge body 100, and the first buffer mechanism is disposed between the first assembly 200 and the transition connector 210.

[0052] By connecting the first assembly 200 and the bridge body 100 through the transition connector 210 , the installation of the first buffer mechanism is facilitated, and the connection between the first assembly 200 and the bridge body 100 is facilitated.

[0053] The first assembly body 200 is in a strip-shaped structure as a whole. The first assembly body 200 has a plurality of plug-in columns 220 arranged at intervals along the length direction. The transition connector 210 has a plurality of plug-in holes 211 arranged at intervals along the length direction. The plug-in columns 220 and the plug-in holes 211 form a plug-in or separate fit.

[0054] The first buffer mechanism includes a shock-absorbing ring 230 sleeved on the plug-in column 220, and a linkage mechanism is provided between multiple groups of plug-in columns 220 and the shock-absorbing ring 230. When the plug-in column 220 and the transition connector 210 are plugged in, the linkage mechanism links the shock-absorbing ring 230 to protrude into the plug-in hole 211 of the transition connector 210 and form abutment connection.

[0055] When the shock-absorbing ring 230 protrudes into the plug hole 211 , the first assembly body 200 and the transition connector 210 can be effectively connected, and the shock-absorbing ring 230 can effectively absorb impact energy.

[0056] Specifically, the plug-in column 220 is vertically slidably mounted on the first assembly body 200, and the upper end of the plug-in column 220 is abutted against the support column 221 via a first support spring 222. The upper end of the shock-absorbing ring 230 is connected to the shock-absorbing tube 231, which is vertically slidably mounted on the first assembly body 200 and sleeved onto the plug-in column 220. A second support spring 232 is sleeved onto the shock-absorbing tube 231, and the two ends of the second support spring 232 respectively abut against the protruding end of the shock-absorbing ring 230 and the first assembly body 200.

[0057] During actual installation, the multiple groups of plug-in columns 220 on the first assembly body 200 are plugged into the transition connector 210 , and the shock-absorbing rings 230 on the plug-in columns 220 are also connected to the transition connector 210 .

[0058] The provision of the shock-absorbing ring 230 can absorb the vibration generated between the first assembly 200 and the bridge body 100, thereby avoiding vibration waves generated during the actual connection process of the two groups of bridge bodies 100, and effectively avoiding the problem of reduced service life caused by cracks generated by the connection of the two groups of bridge bodies 100.

[0059] In this embodiment, when implementing the linkage between the plug-in column 220 and the shock-absorbing ring 230, the linkage mechanism includes a linkage support plate 223 provided at the upper end of the plug-in column 220, a driven support plate 233 provided at the protruding end of the shock-absorbing tube 231, and a linkage rocker plate 240 provided between the linkage support plate 223 and the driven support plate 233. The linkage rocker plate 240 is generally in the shape of a groove plate and is provided with a first driving roller 241 and a second driving roller 242 at its ends, respectively. The first driving roller 241 abuts against the upper surface of the linkage support plate 223, and the second driving roller 242 abuts against the upper surface of the driven support plate 233. The middle section of the linkage rocker plate 240 is hingedly connected to the column body of the support column 221, and the hinge axis of the linkage rocker plate 240 is horizontal and perpendicular to the plug-in column 220.

[0060] After the above-mentioned plug-in column 220 is inserted into the multiple plug-in holes 211 of the transition connector 210, the end face of the plug-in column 220 abuts against the bridge body 100, so that the linked support plate 223 drives the linked rocker plate 240 to abut against the driven support plate 233, thereby causing the shock-absorbing ring 230 to protrude from the first assembly body 200, so that the shock-absorbing ring 230 can be inserted into the plug-in hole 211.

[0061] As the combination position is used and the plug-in column 220 is used, the plug-in column 220 can be inserted tighter and tighter, so that the connection between the shock-absorbing ring 230 and the transition connector 210 can be made more and more stable with increasing use.

[0062] In order to further improve the use effect, the shock-absorbing ring 230 has a conical structure that is small at the bottom and large at the top. An expansion ring 234 is provided on the outer wall of the upper tube mouth of the shock-absorbing ring 230, and a plug-in opening 235 is provided on the inner wall of the upper tube mouth of the shock-absorbing ring 230. The plug-in opening 235 is a conical chamber that is small at the bottom and large at the top, and the shock-absorbing tube 231 is inserted into the plug-in opening 235.

[0063] In this embodiment, the first buffer mechanism includes a damping plate 250 disposed on the side where the first assembly 200 meets the bridge body 100. The damping plate 250 is horizontally slidably mounted on one side of the first assembly 200 and extends along the length of the first assembly 200. A plug-in post 220 is connected to the damping plate 250 via a drive connection unit. When the plug-in post 220 and the transition connector 210 are plugged together, the drive connection unit drives the damping plate 250 to protrude out of the first assembly 200 and abut against the side of the bridge body 100.

[0064] like Figures 8-11 As shown, when the shock-absorbing plate 250 is driven, when the plug-in column 220 is plugged into the transition connector 210, the driving flange 236 abuts against the linkage ring 2541, thereby linking the driving wedge 254 to move vertically to drive the driving roller 253, thereby achieving horizontal driving of the shock-absorbing plate 250, so that the shock-absorbing plate 250 can effectively abut against one side of the bridge body 100, and a reset spring is provided on the driving arm 252, which can effectively realize the reset of the driving arm 252.

[0065] Specifically, the drive connection unit includes a coupling wheel 251 arranged at both ends of the shock-absorbing plate 250, and a driving arm 252 is provided on the outer cover of the coupling wheel 251. The driving arm 252 is slidingly arranged at both ends of the first assembly 200, and a driving roller 253 is provided at the cantilevered end of the driving arm 252. The driving roller 253 abuts against the driving wedge 254. A connecting ring 2541 is extended from one end of the driving wedge 254. A driving flange 236 is provided on the plug-in column 220. The connecting ring 2541 is sleeved on the plug-in column 220, and the driving flange 236 abuts against or separates from the connecting ring 2541.

[0066] About the second assembly:

[0067] like Figure 4-Figure 6 As shown, in order to realize the connection between the first assembly 200 and the second assembly 300, so that the two assemblies form a shock-absorbing connection body, the second assembly 300 is generally in the shape of a strip plate, and the lower plate surface of the second assembly 300 forms a rolling fit with the bridge body 100. The assembly sides of the first assembly 200 and the second assembly 300 are provided with plug-in tubes 260, and the plug-in tubes 260 are arranged in multiple groups at intervals along the length direction of one side of the first assembly 200. The second buffer mechanism includes a buffer rubber ring 261 arranged in the plug-in tube 260, and a coupling plug 310 is provided on one side of the second assembly 300. The coupling plug 310 and the buffer rubber ring 261 form a plug-in or separation fit.

[0068] In addition, an adjustment assembly 400 is provided between the second assembly 300 and another group of bridge bodies 100 . The adjustment assembly 400 is used to adjust the distance between the second assembly 300 and the first assembly 200 . The adjustment assembly 400 is connected and fixed to another group of bridge bodies 100 .

[0069] On the one hand, by adjusting the assembly 400, the coupling plug 310 of the second assembly 300 and the buffer rubber ring 261 form a plug-in fit, thereby realizing the connection between the first assembly 200 and the second assembly 300, and eliminating the vibration generated at the connection between the first assembly 200 and the second assembly 300, thereby improving the service life.

[0070] On the other hand, by adjusting the distance between the second assembly 300 and the first assembly 200 through the adjusting assembly 400, the second assembly 300 is assembled with the first assembly 200, and the adjusting assembly 400 is connected and fixed to another group of bridge bodies 100, thereby achieving stable assembly between the first assembly 200, the second assembly 300 and the adjusting assembly 400 and the bridge body, eliminating errors occurring in the construction of the bridge body, and improving the fault tolerance rate.

[0071] Specifically, the adjustment assembly 400 is provided with an adjustment wedge 410, and the adjustment wedge 410 is connected to an adjustment screw 420 through an adjustment nut, and the other end of the adjustment screw 420 is rotatably provided on the adjustment assembly 400. Figure 7 As shown, the second assembly body 300 includes an adjusting inclined surface 350 having an adjusting roller 351 . The rim of the adjusting roller 351 protrudes from the adjusting inclined surface 350 , and the adjusting wedge 410 abuts against the adjusting roller 351 .

[0072] By screwing the adjusting screw 420 , the adjusting wedge 410 moves downward, and the adjusting wedge 410 abuts against the adjusting inclined surface 350 , driving the adjusting assembly 400 to slide along the bridge body 100 , thereby achieving the combination between the second assembly 300 and the first assembly 200 .

[0073] Furthermore, the lower plate surface of the second assembly 300 is provided with an array of balls 360, which abut against the bridge body 100, and the adjusting rollers 351 are arranged in an array on the adjusting inclined surface 350, the rims of the adjusting rollers 351 protrude from the adjusting inclined surface 350, and the adjusting wedge 410 abuts against the adjusting rollers 351.

[0074] In this embodiment, in order to achieve a buffered connection between the first assembly 200 and the second assembly 300, a coupling pad 320 is slidably provided on the coupling plug 310. The coupling pad 320 is generally in the shape of a strip and its two sides are respectively against one side of the first assembly 200 and the second assembly 300.

[0075] A first bonding buffer plate 330 and a second bonding buffer plate 340 are provided on both sides of the bonding pad 320. The first bonding buffer plate 330 and the second bonding buffer plate 340 are arranged along the length direction of the bonding pad 320. One side of the first bonding buffer plate 330 abuts against one side of the first assembly 200, and one side of the second bonding buffer plate 340 abuts against one side of the adjustment assembly 400.

[0076] A first bonding buffer plate 330 and a second bonding buffer plate 340 are arranged on both sides of the bonding pad 320, and one side of the first bonding buffer plate 330 abuts against one side of the first assembly 200, and one side of the second bonding buffer plate 340 abuts against one side of the adjustment assembly 400. A buffer connection is made between the first assembly 200 and the second assembly 300 through the first bonding buffer plate 330, which can effectively eliminate vibration. One side of the second bonding buffer plate 340 abuts against one side of the adjustment assembly 400, which can realize the overall connection between the first assembly 200 and the second assembly 300.

[0077] In order to implement the abutment between the first bonding buffer plate 330 on one side of the bonding pad 320 and one side of the first assembly 200, a strap 321 is provided on the bonding pad 320. The strap 321 has a vertical surface and is provided with through holes at intervals. The bonding plug 310 passes through the through holes and is sleeved with a bonding spring 323. The two ends of the bonding spring 323 respectively abut against the strap 321 and one side of the second assembly 300.

[0078] When the coupling plug 310 passes through the through hole and forms a plug-in fit with the buffer rubber ring 261, it can also drive the first coupling buffer plate 330 on one side of the coupling pad 320 to abut against one side of the first assembly 200, and compress the coupling spring 323. The compression elastic force of the coupling spring 323 is used to combine the first coupling buffer plate 330 with one side of the first assembly 200.

[0079] Furthermore, the second combining buffer plate 340 is slidingly arranged on the combining pad 320, and a combining extrusion plate 311 is slidingly arranged on the rod of the combining plug 310 extending out of the strap 321. An extrusion spring 312 is sleeved on the rod of the combining plug 310 extending out of the strap 321, and a driving connecting plate 313 is arranged at the perforated hole position of the strap 321, and the driving connecting plate 313 is fixed to the second combining buffer plate 340.

[0080] When the second combined buffer plate 340 is driven, when the combined plug 310 passes through the through hole and forms a plug-in fit with the buffer rubber ring 261, the combined extrusion plate 311 abuts against the plug-in tube 260, thereby compressing the extrusion spring 312, and in conjunction, one side of the second combined buffer plate 340 abuts against the combined adjustment assembly 400.

[0081] Specifically, if Figure 2 and Figure 3 As shown, in order to achieve the sliding connection between the second combining buffer plate 340 and the combining pad 320, multiple groups of sliding guide plates 341 are cantilevered on the second combining buffer plate 340, and the multiple groups of sliding guide plates 341 are arranged along the length direction of the second combining buffer plate 340. The multiple groups of sliding guide plates 341 are slidably set on the combining pad 320.

[0082] Based on the above assembly structure of the continuous rigid frame bridge, this embodiment further provides a construction method of the continuous rigid frame bridge, comprising the following steps:

[0083] A. The bridge body 100 is constructed section by section by tying steel cages and supporting formwork;

[0084] The bridge piers are constructed, and the bridge body 100 is constructed on the top of the bridge piers. During the bridge body construction, the bridge body 100 is constructed section by section by tying steel cages and supporting formwork.

[0085] B. Prefabricate the installation positions of the first assembly 200, the second assembly 300, and the adjustment assembly 400 at the joints of adjacent bridge bodies 100;

[0086] When the bridge bodies 100 of two adjacent bridge piers are close to each other, installation positions for the first assembly 200 , the second assembly 300 and the adjustment assembly 400 are prefabricated at the joint of the bridge bodies 100 .
