Description

Technical Field

[0001] This invention belongs to the field of bridge construction reinforcement technology, specifically relating to a composite reinforcement structure for bridge beam supports adapted to damage conditions. Background Technology

[0002] As a key torsional load-bearing component of a bridge, bridge beam supports bear the reciprocating dynamic loads of vehicles, eccentric torsion, and the effects of outdoor temperature changes and rainwater erosion over a long period of time. The top arc transition area is prone to problems such as concrete cracking, surface peeling, and loosening defects. Therefore, reinforcement structures are needed for bridge maintenance, and thus reinforcement structures are widely used in the repair and structural strengthening of highway and municipal bridges.

[0003] Existing bridge girder support reinforcement methods mostly employ rigid clamps for direct clamping, while some flexible padding reinforcement structures rely solely on a solid rubber pad passively adhering to the column surface. This results in poor adaptability to damage conditions, and when the column surface has defects such as unevenness, peeling, or cracks, it is prone to problems like incomplete adhesion and localized gaps, failing to achieve full-area adhesion reinforcement. Furthermore, traditional reinforcement structures have poor interface sealing, allowing rainwater to easily enter the concrete defects through structural gaps after reinforcement, causing secondary structural damage such as steel corrosion, crack expansion, and concrete freeze-thaw cycles, leading to poor reinforcement durability. In addition, the flexible padding is exposed to high outdoor temperatures for extended periods, and under the influence of sunlight and structural friction heat, the rubber padding is prone to high-temperature aging and deformation failure, while the steel structure is susceptible to temperature stress deformation. After long-term service, the performance of the reinforced structure significantly deteriorates, making it difficult to guarantee stability and service life. Therefore, a composite reinforcement structure for bridge girder supports that adapts to damage conditions is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed composite reinforcement structure for bridge beam supports that is suitable for damage conditions in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A composite reinforcement structure for bridge beam supports adapted to damaged conditions includes a lifting frame. Guide frames are fixed at both ends of the bottom of the lifting frame. Limiting wheels are rotatably connected to the guide frames, and the limiting wheels abut against the side walls of the beam support columns. The beam support columns are located between the lifting frame and the guide frames. Support frames are symmetrically fixed to the lifting frame, and outer supports are slidably connected to both ends of the support frames. An inner support assembly and a side guide mechanism are provided on the outer supports. The inner support assembly includes inner clamping plates symmetrically fixed to the outer supports. A connecting portion is fixed between the inner clamping plates and the outer supports. An adhesive backing portion is fixed to the inner side of the outer supports between the connecting portions. An expansion portion is fixed to the adhesive backing portion, and a puncture portion is fixed at the center of the expansion portion. An inflation chamber is provided between the adhesive backing portion, the puncture portion, and the expansion portion. An external inflation mechanism connected to the inflation chamber is provided on the outer supports. A side air outlet mechanism is provided on the inner clamping plates, and a puncture mechanism is provided on the guide frames.

[0006] As a further optimization of the present invention, the external inflation mechanism includes a support platform fixed on an external support, a connecting tube fixedly sleeved in the support platform, one end of the connecting tube being fixed to the adhesive backing, and the connecting tube communicating with the inflation chamber.

[0007] As a further optimization of the present invention, a filter shell is installed at the other end of the connecting pipe, and an air inflator is provided on the filter shell.

[0008] As a further optimization of the present invention, a pressure sensor is installed on the inflation tube, and a valve is provided in the inflation tube.

[0009] As a further optimization of the present invention, the side exhaust mechanism includes oblique exhaust grooves evenly distributed on the side wall of the inner clamping plate, and the connecting part is provided with a docking groove at the position corresponding to the oblique exhaust groove.

[0010] As a further optimization of the present invention, the puncture mechanism includes a side support plate fixed on the guide frame, and a plurality of puncture heads are fixed on the side support plate at the position corresponding to the puncture part.

[0011] As a further optimization of the present invention, the inner wall of the outer support is provided with an inner groove corresponding to the side support plate, and the outer support is provided with a through hole for the puncture head to pass through.

[0012] As a further optimization of the present invention, the side guide mechanism includes a hollow interlayer disposed within the outer support, a lower slot communicating with the hollow interlayer is provided at the bottom of the outer support, and a receiving pipe is fixed to the top of one side of the outer support, the receiving pipe communicating with the hollow interlayer.

[0013] As a further optimization of the present invention, the outer support is provided with reinforcing ribs evenly distributed.

[0014] As a further optimization of the present invention, lifting rings are symmetrically arranged on the top of the lifting frame.

[0015] The beneficial effects of this invention are as follows: 1. The present invention achieves overall hoisting and displacement through the lifting frame and hoisting ring. During the hoisting operation, the limiting wheel connected to the guide frame always rolls and limits against the side wall of the beam support column, which can effectively restrain the swaying and radial displacement of the entire steel structure. It avoids direct collision, bumping, and squeezing of the column arc surface by the external support, support frame and other hard steel structures during the hoisting process, thus protecting the original loose, cracked and peeling concrete structure from secondary damage. At the same time, it achieves precise positioning of the device and reduces the deviation of high-altitude hoisting construction.

[0016] 2. During the closing and pushing process of the external support of this invention, the Y-shaped piercing head on the guide frame can squeeze and pierce the piercing part in the center of the expansion part, forming a regular Y-shaped pressure relief air hole on the outside of the inflation chamber; the pre-filled clean high-pressure air can be sprayed outward at high speed through the Y-shaped air hole, and together with the inclined exhaust groove of the inner clamp plate and the docking groove of the connecting part, a multi-way blowing airflow is formed to thoroughly flush the column cracks, remove residual dust, loose aggregate and hidden impurities in the peeling pit, and perform secondary cleaning after manual treatment, which solves the problem of incomplete manual cleaning and residual impurities in dead corners, and ensures the quality of reinforcement construction.

[0017] 3. After the external support of this invention is fully compressed, the gas inside the inflation chamber is completely discharged, and the expansion part collapses under pressure, forming an integrated composite elastic compression layer together with the adhesive backing. The elastic compression layer can adapt to defects such as unevenness, peeling, and cracks on the top arc surface of the beam support column, flexibly adhering to the concrete surface, replacing the traditional rigid hard contact reinforcement method, and avoiding further damage to the concrete from rigid compression. At the same time, the fully compacted elastic structure can seal the tiny gaps at the reinforcement interface, forming a closed-loop sealing barrier, effectively preventing rainwater from entering the original concrete defects, preventing secondary diseases such as steel corrosion, crack expansion, and concrete freeze-thaw, and providing long-term protection for the damaged column structure.

[0018] 4. This invention connects to the bridge drainage pipe or external water-cooling pipe through the receiving pipe of the side guide mechanism. The water can continuously flow into the hollow interlayer inside the outer support and circulate. The water flow heat exchange continuously removes the heat accumulated from the high temperature of sunlight and dynamic load friction between the steel structure and the elastic compression layer. This effectively reduces the probability of high temperature aging, cracking and failure of the rubber pad layer, reduces the temperature stress deformation of the steel structure, avoids the performance degradation problem of the reinforcement system under high temperature environment, and greatly improves the long-term service stability and service life of the entire composite reinforcement structure.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: Please refer to Figures 1-9A composite reinforcement structure for bridge beam supports adapted to damaged conditions includes a lifting frame 1. Guide frames 2 are fixed to both ends of the bottom of the lifting frame 1. Lifting rings 10 are symmetrically fixed to the top of the lifting frame 1. Limiting wheels 3 are rotatably connected to the guide frames 2 via bearings. The limiting wheels 3 abut against the side wall of the beam support column 4, which is located between the lifting frame 1 and the guide frames 2. Support frames 5 are symmetrically fixed to the lifting frame 1. External supports 6 are slidably connected to both ends of the support frames 5. Reinforcing ribs 9 are evenly distributed on the external supports 6. Inner... Support component 7 and side guide mechanism 8; The top arc section of the beam support column 4 is the main torsional bearing area of ​​the bridge. It is subjected to the eccentric load and reciprocating vibration of vehicles for a long time, which is prone to damage and defects such as cracks, surface peeling and concrete loosening. When the defects are detected, the guide frame 2, support frame 5 and outer support 6 are erected at the bottom of the beam support column 4 and lifted to the height of the part that needs to be repaired by the lifting ring 10. Then the support frame 5 is pushed towards the center to form a ring-shaped reinforcement structure to reinforce the damaged bridge beam support column 4.

[0023] Please see Figures 2-4 , Figure 6 and Figure 9 The inner support assembly 7 includes an inner clamping plate 71 symmetrically fixed to the outer support 6. A connecting part 72 is fixed between the inner clamping plate 71 and the outer support 6. The connecting part 72 can be made of glass fiber fabric composite dense neoprene rubber and is tightly pressed between the inner clamping plate 71 and the outer support 6. An adhesive backing part 73 is fixed between the connecting parts 72. The adhesive backing part 73 is adhered to the inner side of the outer support 6. The adhesive backing part 73 can be made of rigid reinforcing neoprene rubber and is bonded to the outer support 6 by a pre-coated epoxy rubber primer, so that it will not peel off or lift. An expansion part 74 is fixed on the adhesive backing part 73. The expansion part 74 can be made of soft neoprene rubber and can produce elastic deformation under force. A puncture part 75 is fixed at the center of the expansion part 74. The puncture part 75 can be made of neoprene rubber filled with aramid short fibers, with low deformation and no tearing cracks after being punctured by external force. The adhesive backing part 73 and the puncture part 74 are also fixed to the outer support 6. The outer support 75 and the expansion part 74 constitute a complete inflation chamber 76. An external inflation mechanism 77 is provided on the outer support 6 to connect the inflation chamber 76. The external inflation mechanism 77 is used to fill the inflation chamber 76 with gas. A side air outlet mechanism 78 is provided on the inner clamping plate 71. During the process of the support frame 5 being pushed towards the center to form a ring-shaped reinforcement structure, the side air outlet mechanism 78 can guide the airflow, allowing the airflow carrying impurities to be discharged from the side. A puncture mechanism 79 is provided on the guide frame 2. During the inflation process, the adhesive part 73 is fixed and does not expand, achieving overall structural fit and fixation. The expansion part 74 can be inflated and expands elastically. During the process of the outer supports 6 approaching each other, the puncture part 75 is the corresponding puncture force area, which can form a pressure relief vent after being punctured under pressure. After the outer support 6 is tightly hugged on the beam support column 4, the expansion part 74 can adapt to the concave and convex defects of the column's arc surface under pressure, reinforcing and sealing the reinforced part.

[0024] Please see Figures 2-3 and Figures 6-7 The external inflation mechanism 77 includes a support platform 771 fixed on the external support 6. A connecting pipe 772 is fixedly sleeved in the support platform 771. One end of the connecting pipe 772 is fixed on the adhesive backing part 73 and is connected to the inflation chamber 76. A filter shell 773 is installed at the other end of the connecting pipe 772. An inflation pipe 774 is provided on the filter shell 773. An air pressure sensor is installed on the inflation pipe 774. A valve for regulating the air passage is provided in the inflation pipe 774. The external inflation mechanism 77 is used to perform constant pressure clean inflation of the inflation chamber 76. The filter shell 773 can effectively filter out water vapor, dust and impurities in the compressed air, preventing impurities from entering the inflation chamber 76 or remaining inside the concrete cracks after subsequent blowing. The air pressure sensor can monitor the air pressure in the chamber in real time to ensure that the inflation pressure is stable and controllable, and to avoid damage due to overpressure or insufficient pressure leading to inadequate expansion and fit.

[0025] Please see Figure 3 , Figure 6 and Figure 9 The side exhaust mechanism 78 includes oblique exhaust grooves 781 evenly distributed on the side wall of the inner clamping plate 71, and the connecting part 72 is provided with a docking groove 782 at the position corresponding to the oblique exhaust grooves 781. The side exhaust mechanism 78 can cooperate with puncture and depressurization to form multiple airflow channels, forming a lateral auxiliary blowing airflow while purging, cleaning the impurities remaining on the arc-shaped damaged surface of the column in all directions, further improving the interface cleanliness, ensuring that the subsequent bonding is tight and there is no risk of separation, and at the same time preventing the expansion part 74 from being crushed by impurities after being pressed.

[0026] Please see Figures 2-3 and Figure 5 The puncture mechanism 79 includes a side support plate 791 fixed on the guide frame 2. The side support plate 791 has multiple Y-shaped protruding puncture heads 792 fixed at the position corresponding to the puncture part 75. The inner wall of the outer support 6 is provided with an inner groove corresponding to the side support plate 791, and the outer support 6 is provided with a through hole for the puncture heads 792 to pass through. During the closing and pushing process of the outer support 6, it will approach the side support plate 791 in the puncture mechanism 79. The puncture heads 792 on the side support plate 791 will squeeze the puncture part 75 and puncture as the pressure increases. A regular Y-shaped pressure relief vent is formed at the center of the expansion part 74, realizing controllable automatic opening, automatic pressure relief, and automatic purging. No manual opening is required, which is suitable for high-altitude and narrow working conditions.

[0027] Please see Figure 2 , Figure 6 and Figures 8-9The side flow guiding mechanism 8 includes a hollow interlayer 81 formed within the outer support 6. The bottom of the outer support 6 has a lower slot for water to flow out, which is connected to the hollow interlayer 81. A receiving pipe 82 is fixed to the top of one side of the outer support 6, and the receiving pipe 82 is connected to the hollow interlayer 81. The side flow guiding mechanism 8 can be connected to the bridge drainage system or an external water cooling pipeline. Water flows through the receiving pipe 82 into the hollow interlayer 81 within the outer support 6, flows along the interlayer for heat exchange, and then flows out from the lower slot, carrying away the heat generated by long-term sunlight exposure and dynamic load friction of the reinforced structure. This reduces the aging rate of the rubber pad and the temperature stress of the steel structure, and significantly improves the long-term service durability of the reinforcement system.

[0028] It should be noted that this composite reinforcement structure for bridge beam supports adapted to damaged conditions is first arranged on the outer side of the damaged area at the top of the beam support column 4 to be reinforced. During the arrangement, the lifting frame 1 and the guide frame 2 are clamped on both sides of the beam support column 4, so that the limiting wheels 3 on the guide frame 2 are in contact with the side wall of the column, ensuring that the overall alignment of the device is regular and without offset interference. The outer supports 6 are slidably assembled at both ends of the support frame 5, so that the two sets of outer supports 6 symmetrically surround the outside of the column, forming a ring-shaped reinforcement structure. A temporary limiting structure is added to the end of the support frame 5 to prevent the outer supports 6 from accidentally slipping and falling off during hoisting and pushing, ensuring construction safety. After the device is pre-installed and positioned, the inflation pipe 774 is connected to the air compressor equipment on the construction site. Compressed air is filled into the inflation chamber 76 through the external inflation mechanism 77. During the inflation process, the compressed air first passes through the filter shell 773 to filter out oil, water and impurities, ensuring that the airflow entering the inflation chamber 76 is clean and dry. The air pressure sensor on the inflation pipe 774 collects the air pressure data inside the inflation chamber 76 in real time. After the air pressure reaches the preset construction threshold, the valve on the inflation pipe 774 is closed, the air supply is stopped and the air compressor connection pipeline is disconnected, completing the device pre-inflation and pre-expansion process. At this time, the expansion part 74 bulges inward as a whole, which is ready for subsequent bonding and purging operations. After pre-inflation, the lifting frame 1, guide frame 2, support frame 5 and outer support 6 are lifted as a whole by connecting the lifting equipment to the lifting ring 10 at the top of the lifting frame 1. During the lifting displacement, the limiting wheel 3 on the guide frame 2 always rolls and limits against the side wall of the beam support column 4, effectively preventing the steel structure from shaking, shifting and colliding and damaging the original concrete structure, until the device is accurately suspended to the height position corresponding to the cracked and peeled damaged arc segment at the top of the beam support column 4, and the construction alignment is completed. After the device is aligned, the two outer supports 6 are pushed inward and closed along the support frame 5 by the external pushing device. During the pushing process of the outer supports 6, the piercing head 792 on the side support plate 791 gradually approaches and contacts the piercing part 75 in the center of the expansion part 74. As the outer supports 6 continue to press and push inward, the piercing head 792 squeezes and pierces the piercing part 75, forming multiple regular Y-shaped pressure relief gaps in the center of the expansion part 74, so that the inside of the inflation chamber 76 is completely connected to the outside. After the puncture and opening are completed, the high-pressure air inside the air chamber 76 is rapidly ejected outward from the Y-shaped notch. The high-speed airflow can directly flush the arc-shaped damaged working surface at the top of the beam support column 4 again after manual cleaning, and blow away the dust, loose aggregate and impurities remaining in the cracks and pits for a second time. At the same time, some airflow can be ejected laterally through the docking groove 782 of the connecting part 72 and the oblique exhaust groove 781 of the inner clamping plate 71, forming a multi-directional blowing airflow. On the basis of the initial manual leveling, the reinforced interface is further cleaned and refined to prevent the problem of subsequent bonding failure caused by the residue of impurities, and to ensure that the reinforced interface is clean and dense. After the interface is cleaned by blowing, the outer supports 6 on both sides are continuously pressed inward, so that the outer supports 6 are completely attached to and clamped on the outside of the beam support column 4. Under the compression, the gas inside the air chamber 76 is continuously and completely discharged from the Y-shaped notch. The expansion part 74 is compressed and repositioned, changing from an inflated state to a solid elastic pad state. At this time, the adhesive backing part 73 and the collapsed expansion part 74 together form a composite flexible compression layer, which closely adheres to the damaged arc surface of the column and forms a uniform flexible constraint on the cracked and peeled concrete area, avoiding further damage to the concrete by rigid clamping. After the outer support 6 is clamped and positioned, the excess structure of the support frame 5 is cut off, and the outer support 6 is welded and fixed to the support frame 5 to achieve permanent positioning and reinforcement of the entire device. After clamping and molding, the expansion part 74 and the adhesive part 73 are completely compacted and sealed, sealing all the tiny gaps in the reinforcement interface. Together with the overall encircling structure, it blocks external rainwater from entering the original concrete defect area, effectively inhibiting the expansion of cracks and the continuous development of structural corrosion problems. After the reinforcement is completed, the bridge's pre-installed drainage pipes or external cold water pipes can be connected to the receiving pipe 82. During daily operation and maintenance, the bridge's natural drainage or cold water can be introduced periodically. The water flows through the receiving pipe 82 into the hollow interlayer 81 inside the outer support 6. After heat exchange along the interlayer, it flows out from the lower slot, continuously carrying away the accumulated heat of the composite compression layer and the steel structure. This effectively reduces the risk of high-temperature aging of the rubber pad and temperature stress deformation of the steel structure, and significantly improves the long-term service stability and durability of the entire reinforcement structure.

[0029] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
