Description

Technical Field

[0001] This application relates to the field of bridge reinforcement technology, and in particular to beam reinforcement systems. Background Technology

[0002] In related technologies, bridges typically consist of multiple beams, each independently constructed. When a vehicle passes over a single beam, the load cannot be effectively redistributed among the beams, resulting in uneven stress distribution. Some beams may be severely overloaded, while others fail to fully utilize their load-bearing capacity, making some beams highly susceptible to damage, reducing their service life, and decreasing the overall stability of the bridge. Utility Model Content

[0003] Therefore, it is necessary to provide a beam reinforcement system to address the problem that the lack of connection between beams leads to some beams being easily damaged due to excessive load.

[0004] A beam reinforcement system, comprising:

[0005] Multiple beams, at least two beams are distributed at intervals along a first direction, each beam includes a top plate and a support plate, the top plate being positioned above the support plate;

[0006] The reinforcement mechanism is set between the support plates of two adjacent beams along the first direction. The reinforcement mechanism abuts against the two support plates. The line connecting the reinforcement mechanism and the two support plates extends along the second direction. The second direction and the first direction have an angle of less than 90°.

[0007] In one embodiment, the two ends of the reinforcing mechanism are respectively fixedly connected to the support plates of two adjacent beams along the first direction;

[0008] The reinforcement mechanism includes a reinforcement component, which includes an energy-absorbing unit that extends along a second direction in its longitudinal direction to dissipate the load transmitted by the beam.

[0009] In one embodiment, the reinforcement component further includes:

[0010] The first connector has one end fixed to the support plate and the other end detachably connected to the energy absorption unit. The length of the first connector extends along the second direction.

[0011] In one embodiment, the energy absorption unit includes:

[0012] The fastener has a first fixing cavity, and one end of the first connector is fixed inside the first fixing cavity;

[0013] The first elastic element is disposed between the first fixed cavity and the first connecting member to dissipate the load transmitted by the beam.

[0014] In one embodiment, the reinforcement mechanism includes two reinforcement components, one end of which is fixedly connected to two adjacent beams along a first direction, and the other ends of the two reinforcement components are fixedly connected to each other.

[0015] In one embodiment, both reinforcement components further include a second connector, one end of which is detachably connected to the energy-absorbing unit of the same reinforcement component, and the other end of which is fixedly connected to the second connector of another reinforcement component.

[0016] In one embodiment, the beam reinforcement system includes a plurality of reinforcement mechanisms, at least two of which have an included angle.

[0017] In one embodiment, the beam reinforcement system further includes:

[0018] Reinforcing ribs connect two adjacent reinforcement mechanisms.

[0019] In one embodiment, the beam further includes a fixing seat disposed below the support plate; one end of the reinforcing mechanism abuts against the end of the support plate in one of the beams near the top plate, and the other end of the reinforcing mechanism abuts against the end of the support plate in another beam near the fixing seat.

[0020] In one embodiment, the beam reinforcement system further includes:

[0021] A reinforcing plate covers the outside of the supporting plate, and a reinforcing mechanism abuts against the reinforcing plate.

[0022] In the aforementioned beam reinforcement system, the reinforcement mechanism abuts against the support plates of two adjacent beams along a first direction. The line connecting the abutment point of the reinforcement mechanism and the two support plates extends along a second direction, and the angle between the second direction and the first direction is less than 90°, meaning there is an angle between the reinforcement mechanism and the support plates. When a load is applied to a single beam, due to the angle between the reinforcement mechanism and the support plates, the force acting on the top plate is decomposed and transformed into a tensile force along the second direction when transmitted to the reinforcement mechanism. This tensile force can be transmitted to adjacent beams, allowing multiple beams to share the load. This achieves effective load redistribution among the beams, reducing the possibility of severe overloading of some beams while others fail to fully utilize their load-bearing capacity. This reduces the likelihood of beam damage, increases beam lifespan, and ensures the overall stability of the bridge. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figure 1This application provides a beam reinforcement system comprising multiple beams 10 and a reinforcement mechanism 20. At least two beams 10 are spaced apart along a first direction, and each beam 10 includes a top plate 11 and a support plate 12, with the top plate 11 positioned above the support plate 12. The reinforcement mechanism 20 is disposed between the support plates 12 of two adjacent beams 10 along the first direction, abutting against the two support plates 12. The line connecting the abutment point of the reinforcement mechanism 20 and the two support plates 12 extends along a second direction, forming an angle less than 90° with the first direction. (See reference...) Figure 1 The X direction is the first direction, and the Y or Z direction is the second direction.

[0044] Applying the technical solution of this application, the reinforcement mechanism 20 abuts against the support plates 12 of two adjacent beams 10 along the first direction. The line connecting the abutment point of the reinforcement mechanism 20 and the two support plates 12 extends along the second direction, and the angle between the second direction and the first direction is less than 90°, that is, there is an angle between the reinforcement mechanism 20 and the support plates 12. When a load is applied to a single beam 10, due to the angle between the reinforcement mechanism 20 and the support plates 12, the force acting on the top plate 11 is decomposed when it is transmitted to the reinforcement mechanism 20, and is converted into a tensile force along the second direction. The tensile force can be transmitted to the adjacent beams 10, so that multiple beams 10 participate in the load-bearing process together, realizing the effective redistribution of the load among the beams 10. This reduces the occurrence of situations where some beams 10 are severely overloaded while other beams 10 fail to fully utilize their load-bearing capacity, reduces the possibility of damage to the beams 10, increases the service life of the beams 10, and ensures the overall stability of the bridge.

[0045] Furthermore, the reinforcement mechanism 20 can also support the beam 10 to achieve the reinforcement effect of the beam 10.

[0046] In some embodiments, beam 10 is a T-beam, top plate 11 is a flange, and support plate 12 is a web.

[0047] In some embodiments, the support plate 12 is arranged in a vertical direction, and the first direction is a horizontal direction.

[0048] See Figure 1 The two ends of the reinforcement mechanism 20 are fixedly connected to the support plates 12 of two adjacent beams 10 along the first direction. The reinforcement mechanism 20 includes a reinforcement component 21, which includes an energy-absorbing unit 211. The energy-absorbing unit 211 extends along the second direction and is used to dissipate the load transmitted by the beams 10. This arrangement facilitates the assembly of the reinforcement mechanism 20 onto the support plates 12, reducing the difficulty of operation for workers. At the same time, when the load is transmitted to the reinforcement mechanism 20, the energy-absorbing unit 211 can absorb and dissipate a portion of the energy, thereby reducing the load transmitted to the beams 10 and further extending the service life of the beams 10.

[0049] See Figure 1 and Figure 3 The reinforcement component 21 also includes a first connector 212. One end of the first connector 212 is fixed to the support plate 12, and the other end is detachably connected to the energy-absorbing unit 211. The length of the first connector 212 extends along the second direction. This configuration allows the load to be directly transferred along the second direction through the first connector 212, avoiding stress concentration caused by structural abrupt changes. Furthermore, when the reinforcement component 21 is damaged, workers do not need to operate the entire reinforcement mechanism 20; they only need to disassemble the damaged energy-absorbing unit 211 or the first connector 212, facilitating the disassembly, repair, and replacement of the reinforcement component 21.

[0050] See Figure 1 and Figure 2 The energy-absorbing unit 211 includes a fixing member 2111 and a first elastic member. The fixing member 2111 has a first fixing cavity 21111, and one end of the first connecting member 212 is fixed inside the first fixing cavity 21111. The first elastic member is disposed between the first fixing cavity 21111 and the first connecting member 212 to dissipate the load transmitted by the beam 10. This arrangement allows the first fixing cavity 21111 to constrain and guide the first elastic member, ensuring that the first elastic member can deform along a preset direction when compressed, thereby improving the stability and reliability of the first elastic member and preventing it from tilting during operation. Furthermore, the first fixing cavity 21111 can protect the first elastic member, reducing contamination from the external environment.

[0051] In some embodiments, the first elastic element is a spring.

[0052] Specifically, the reinforcement mechanism 20 includes two reinforcement components 21. One end of each reinforcement component 21 is fixedly connected to two adjacent beams 10 along the first direction, and the other ends of the two reinforcement components 21 are fixedly connected to each other. This arrangement further improves the convenience of disassembly, maintenance, and replacement of the reinforcement mechanism 20. Furthermore, multiple workers can simultaneously fix different reinforcement components 21 to different beams 10 and then fix the two reinforcement components 21 together, thus improving the installation efficiency of the reinforcement components 21.

[0053] See Figure 1Both reinforcing components 21 also include a second connector 213. One end of the second connector 213 is detachably connected to the energy-absorbing unit 211 of the same reinforcing component 21, and the other end of the second connector 213 is fixedly connected to the second connector 213 of the other reinforcing component 21. This configuration achieves a modular design for the reinforcing components 21, which facilitates processing by workers and enables rapid on-site assembly, significantly improving construction efficiency.

[0054] In some embodiments, the two second connectors 213 are welded together.

[0055] In some embodiments, the energy-absorbing unit 211 further includes a second elastic member, the fixing member 2111 has a second fixing cavity 21112, and one end of the second connecting member 213 is fixed in the second fixing cavity 21112. The second elastic member is disposed between the second fixing cavity 21112 and the second support unit to dissipate the load transmitted by the beam 10.

[0056] In some embodiments, the second elastic element is a spring.

[0057] In some embodiments, the fastener 2111 includes a fastening portion 21113, a first connecting portion 21114, and a second connecting portion 21115. The fastening portion 21113 includes a first fastening cavity 21111 and a second fastening cavity 21112, which are independent of each other. The first connecting portion 21114 is disposed within the first fastening cavity 21111 and has a first external thread. The second connecting portion 21115 is disposed within the second fastening cavity 21112 and has a second external thread. The first connecting member 212 includes a first clearance cavity 2121, and the first connecting portion 21114 is disposed within the first clearance cavity 2121. The inner wall of the first connecting member 212 has a first internal thread, which is threadedly connected to the first external thread. The second connecting member 213 includes a second clearance cavity, and the second connecting portion 21115 is disposed within the second clearance cavity. The inner wall of the second connecting member 213 has a second internal thread, which is threadedly connected to the second external thread. After the reinforcement mechanism 20 is assembled, the first and second elastic elements are in a compressed state. This configuration allows the first and second elastic elements to continuously provide thrust to the first connecting portion 21114 and the second connecting portion 21115, enabling the reinforcement mechanism 20 to provide thrust to the two adjacent support plates 12, thus improving the stability of the reinforcement mechanism 20 fixed between the two support plates 12. Furthermore, the first and second elastic elements can automatically compensate for the deformation of the support plates 12 to a certain extent, ensuring that the reinforcement mechanism 20 and the support plates 12 always maintain contact, thereby improving the reinforcement effect of the reinforcement mechanism 20 and enhancing the stability of the beam reinforcement system.

[0058] In some embodiments, one end of the first elastic member abuts against the first connecting portion 21114, and the other end of the first elastic member abuts against the inner wall of the first clearance cavity 2121.

[0059] In some embodiments, one end of the second elastic member abuts against the second connecting portion 21115, and the other end of the second elastic member abuts against the inner wall of the second clearance cavity.

[0060] In some embodiments, one end of the first elastic member abuts against the inner wall of the first fixing cavity 21111, and the other end of the first elastic member abuts against the end of the first connecting member 212.

[0061] In some embodiments, one end of the second elastic member abuts against the inner wall of the second fixing cavity 21112, and the other end of the second elastic member abuts against the end of the second connecting member 213.

[0062] In some embodiments, the diameter of the first clearance cavity 2121 is not less than two-thirds of the outer diameter of the first connector 212.

[0063] In some embodiments, the diameter of the second clearance cavity is not less than two-thirds of the outer diameter of the second connector 213.

[0064] In some embodiments, the diameter of the first clearance cavity 2121 is not less than two-thirds of the outer diameter of the first connector 212, and the diameter of the second clearance cavity is not less than two-thirds of the outer diameter of the second connector 213. This configuration increases the diameter of the first and second internal threads, thereby enabling the first connector 212 and the second connector 213 to withstand greater loads and improving the strength and durability of the threaded connections between the first connecting portion 21114 and the second connecting portion 21115 and the first connector 212 and the second connector 213, respectively.

[0065] Specifically, the fastener 2111 is a one-piece molded part. This design can avoid potential stress concentration points on the fastener 2111, improve the uniformity of stress distribution when the fastener 2111 is under load, thereby improving the overall strength and structural stiffness of the fastener 2111, and thus improving the load-bearing capacity and service life of the fastener 2111.

[0066] In some embodiments, the fastener 2111 is provided with an injection port for injecting adhesive into the first fixing cavity 21111 and the second fixing cavity 21112. After the adhesive is injected, the injection port can be sealed by a simple one-way valve or by applying other curing agents to the surface.

[0067] In some embodiments, the first connector 212 and the fixing member 2111, and the second connector 213 and the fixing member 2111, are clearance-fitted, and the first connector 212 and the second connector 213 have a certain amount of flexibility. Since the beam 10 may have errors during construction, the position of the connection between the reinforcement mechanism 20 and the beam 10 may change during vibration, thus providing a margin for different axial ratios of the reinforcement mechanism 20.

[0068] See Figure 1 The beam reinforcement system includes multiple reinforcement mechanisms 20, with at least two of the reinforcement mechanisms 20 having an included angle. This arrangement further enhances the reinforcement effect of the beam reinforcement system. Furthermore, in related technologies, the end of the support plate 12 closest to the top plate 11 bears the load first. When at least two reinforcement mechanisms 20 have an included angle, when one of the two beams 10 bears a load, or when one of them bears a larger load, the load can be promptly transferred to the end of the support plate 12 of the other beam 10 furthest from the top plate 11, thus supporting both support plates 12 and further improving the overall stability of the bridge.

[0069] See Figure 1 The beam reinforcement system also includes reinforcing ribs 30, which connect two adjacent reinforcement mechanisms 20. This arrangement improves the structural strength and stability of the reinforcement mechanism 20, thereby ensuring the reinforcement effect of the reinforcement mechanism 20 on the beam 10.

[0070] See Figure 1 The beam 10 also includes a fixing seat 13, which is located below the support plate 12. One end of the reinforcement mechanism 20 abuts against the end of the support plate 12 in one of the beams 10 near the top plate 11, and the other end of the reinforcement mechanism 20 abuts against the end of the support plate 12 in another beam 10 near the fixing seat 13. Since the end of the support plate 12 near the top plate 11 is the main load-bearing area, and the fixing seat 13 is generally fixed to the ground, the end of the support plate 12 near the fixing seat 13 has a more stable structure. With this arrangement, the reinforcement mechanism 20 can transfer the load from the main load-bearing area to the structurally stable area, greatly improving the stability of the beam reinforcement system.

[0071] In some embodiments, the beam reinforcement system includes two reinforcement mechanisms 20, which are at an included angle. One end of one reinforcement mechanism 20 abuts against the end of the support plate 12 in one beam 10 near the top plate 11, and one end of the other reinforcement mechanism 20 abuts against the end of the support plate 12 in the same beam 10 near the fixing seat 13. The other end of one reinforcement mechanism 20 abuts against the end of the support plate 12 in the other beam 10 near the fixing seat 13, and the other end of the other reinforcement mechanism 20 abuts against the end of the support plate 12 in the same beam 10 near the top plate 11. Therefore, the two reinforcement mechanisms 20 are arranged in a one-to-one correspondence with the two beams 10, so that when one of the two beams 10 bears a load or when one of the beams 10 bears a large load, the load can be transferred to the structurally stable area of ​​the other beam 10 in a timely manner.

[0072] See Figure 1 The beam reinforcement system also includes a reinforcement plate 40, which covers the outer side of the support plate 12, and a reinforcement mechanism 20 abuts against the reinforcement plate 40. This arrangement further improves the structural strength of the beam 10, inhibits the initiation and propagation of cracks, and enhances the durability and load-bearing capacity of the beam 10. Furthermore, the reinforcement mechanism 20 can fix the reinforcement plate 40 in place, preventing it from falling off the support plate 12.

[0073] In some embodiments, the two ends of the reinforcing plate 40 extend to the two ends of the support plate 12. One end of the reinforcing mechanism 20 is fixed to one end of the reinforcing plate 40, and the other end of the reinforcing mechanism 20 is fixed to the other end of the reinforcing plate 40.

[0074] In some embodiments, the reinforcing plate 40 is made of a lightweight material and has a certain degree of elasticity. Since the reinforcing plate 40 has a low self-weight, it does not need to be fastened and can be installed by simply pasting.

[0075] In some embodiments, the reinforcing plate 40 is made of carbon fiber cloth or polyethylene sheet.

[0076] In some embodiments, the reinforcing plate 40 is made of fiber-reinforced composite material, preferably carbon fiber reinforced composite material. Carbon fiber reinforced composite material has advantages such as being lightweight, having high specific strength, high specific modulus, corrosion resistance, fatigue resistance, and ease of construction. In particular, its tensile strength can reach more than 1.5 times that of conventional steel strand, which can effectively improve the strength of bridges.

[0077] In some embodiments, the reinforcement mechanism 20 further includes a support 22, which is fixed to the reinforcement plate 40, and the first connector 212 is hinged to the support 22. This configuration allows the angle of the first connector 212 to be changed when fixing the reinforcement mechanism 20, making the reinforcement mechanism 20 applicable to beams 10 with different spacing along the first direction, thus improving the versatility of the reinforcement mechanism 20.

[0078] In some embodiments, the construction process of the reinforcing plate 40 is as follows: site preparation, scaffolding erection, surface cleaning and treatment of beam 10, crack repair of beam 10, installation of reinforcing plate 40, adhesive injection, other operations, addition of drip edge, removal of scaffolding, and site preparation.

[0079] To ensure the quality of the adhesive application on the reinforcement plate 40, the relevant construction should be carried out during the designated maintenance window, and the bridge deck should be free of traffic for no less than 120 minutes after the adhesive application is completed. Simultaneously, the relevant construction should be carried out when the air temperature is not lower than 5℃.

[0080] The construction process for reinforcement plate 40 is as follows:

[0081] Concrete surface treatment: According to the design drawings and combined with on-site measurement and positioning, mark the reinforcement plate position 40 on the surface of the concrete to be reinforced with steel. Remove 2-5mm thick surface mortar from the concrete surface of the area to be reinforced with steel, exposing the solid concrete stone and forming a smooth rough surface. Use a pointed chisel to lightly chisel and level any uneven areas. Then use a wire brush to roughen the surface and remove loose material. Finally, blow away surface dust with oil-free compressed air or rinse with clean water. After it is completely dry, wipe the surface with cotton soaked in acetone.

[0082] Installation of Reinforcing Plate 40: Cut the reinforcing plate 40 according to the actual layout on the concrete site. Then, roughen the bonding surface of the reinforcing plate 40 with a sandblasting machine. The roughness should be as high as possible, and the sanding lines should be perpendicular to the stress direction of the reinforcing plate 40. Wipe the surface of the plate clean with acetone-soaked cotton wool. Fix the reinforcing plate 40 to the bolts, ensuring that the gap between the reinforcing plate 40 and the concrete surface is about 3mm, and ensure that the thickness of the grouting layer is between 3 and 5mm.

[0083] Prepare the structural adhesive: Prepare the structural adhesive according to the proportions specified in the product instructions provided by the supplier. The steel bonding and grouting adhesive should be prepared and used only after the edge sealing is completed and the 40mm edge sealing adhesive of the reinforcing plate has fully cured and has sufficient strength.

[0084] Edge sealing: Attach the injection nozzle to the injection hole of the reinforcing plate 40, insert the vent pipe into the edge of the reinforcing plate 40, cover the expansion bolt head with a cap cup, and then seal the edge of the reinforcing plate 40 with edge sealing adhesive to complete the edge sealing. The injection nozzle spacing is 2-3m.

[0085] Edge sealing: Attach the injection nozzle to the injection hole of the reinforcing plate 40, insert the vent pipe into the edge of the reinforcing plate 40, cover the expansion bolt head with a cap cup, and then seal the edge of the reinforcing plate 40 with edge sealing adhesive to complete the edge sealing. The injection nozzle spacing is 2-3m.

[0086] Injection: Use a pump to inject the bonding adhesive into the gaps between the reinforcing plate 40 and the concrete through the injection nozzle. Injection continues until adhesive flows from all vent pipes. During injection, tap the reinforcing plate 40 with a rubber mallet to confirm compaction. Before grouting, a pressure test is required. Inject the bonding adhesive into the injection nozzle at a pressure of 0.2–0.4 MPa. Stop pressurizing when grout appears in the vent holes, seal the holes with the edge sealant of the reinforcing plate 40, and then maintain a lower pressure for at least 10 minutes.

[0087] The time between the completion of the installation of the reinforcing plate 40 and the injection of the adhesive for steel bonding shall not exceed 24 hours to ensure the bonding effect of the reinforcing plate 40.

[0088] Anti-corrosion treatment of the surface of the reinforcing plate 40: After the reinforcing plate 40 is confirmed to be firmly bonded and cured, all injection nozzles and exhaust pipes are removed, and dirt on the surface of the reinforcing plate 40 is cleaned. Anti-corrosion coating is applied to the local reinforcing plate 40 and anchor bolts where the coating is damaged.

[0089] Installation of reinforcement mechanism 20: First, fix the support 22 and the first connecting piece 212 on the reinforcement plate 40. First, connect the four fixing pieces 2111 to the four first connecting pieces 212 respectively. Then, fix the four second connecting pieces 213 on the four fixing pieces 2111. Weld the four second connecting pieces 213 to fix them.

[0090] In some embodiments, the worker processes the four second connectors 213 and the reinforcing ribs 30 into a single integral connecting assembly. Furthermore, the first connector 212 includes a first connecting body and a first mating thread, the first mating thread being rotatably disposed on the first connecting body and having a first clearance cavity 2121. The second connector 213 includes a second connecting body and a second mating thread, the second mating thread being rotatably disposed on the second connecting body and having a second clearance cavity.

[0091] The installation and fixing process of the processing mechanism is as follows: First, fix the four supports 22 on the reinforcing plate 40. Then, hinge the four first connecting pieces 212 to the four supports 22 respectively. Connect the connecting assembly to the two fixing pieces 2111 above and rotate the first mating screw and the second mating screw simultaneously to achieve fastening. Until it cannot be tightened further by manual rotation in one direction, switch to a pneumatic or electric wrench to further adjust the screw until it is locked in one direction. After adjusting the two first connecting pieces 212 and the energy absorption unit 211 to be coaxial, pull the connecting assembly to switch between the two first connecting pieces 212 and the fixing pieces 2111 below. Repeat the above steps to complete the installation.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
