Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance and reinforcement technology, specifically a reinforcement device for the cross diaphragm of an old bridge. Background Technology

[0002] With the rapid development of my country's transportation industry, bridges, as key nodes in the transportation network, play a vital role. However, many bridges built in the early stages have gradually developed varying degrees of structural defects and damage due to factors such as their age, lower design standards, limited construction technology, and the long-term bearing of increasing traffic loads. As an important component of the bridge structure, the diaphragms of old bridges bear crucial roles in enhancing the lateral stiffness of the bridge, ensuring the coordinated operation of the main beams, and evenly distributing loads. Their performance directly affects the overall stability and safety of the bridge.

[0003] As the service life of old bridge diaphragms increases, cracks and even local damage are likely to occur, which weakens the load-bearing capacity of the bridge. Traditional reinforcement devices for old bridge diaphragms only reinforce individual diaphragms and cannot connect multiple diaphragms into one, thus having limited effect on improving the overall strength. Utility Model Content

[0004] The purpose of this invention is to provide a reinforcement device for the cross diaphragm of old bridges, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A reinforcement device for diaphragms of old bridges includes a U-shaped reinforcement plate and multiple parallel webs disposed on the lower surface of the beam. Multiple diaphragms are disposed between adjacent webs. The U-shaped reinforcement plate covers the outer surface of the diaphragms, and both sides of the U-shaped reinforcement plate are respectively attached to the webs on both sides. A fixed connecting rod is installed on one side of the outer surface of the U-shaped reinforcement plate, and an adjustable connecting rod is disposed on the other side of the outer surface of the U-shaped reinforcement plate. The ends of both the fixed connecting rod and the adjustable connecting rod are equipped with first flanges, and two corresponding first flanges are connected by first bolts and nuts.

[0007] It is evident that by setting fixed and adjustable connecting rods, adjacent U-shaped reinforcing plates can be connected together to form a cohesive whole structure. The U-shaped reinforcing plates can transfer and share forces with each other, enabling the entire bridge structure to resist external forces more effectively. Furthermore, the bridge can distribute stress more evenly when bearing loads, avoiding stress concentration and thus reducing the risk of structural failure.

[0008] Furthermore, the adjustable connecting rod includes a sleeve rod installed on the outer surface of the U-shaped reinforcing plate. The sleeve rod has a threaded groove inside, and a screw rod is inserted into and threadedly connected inside the threaded groove. The first flange is installed at the end of the screw rod.

[0009] Furthermore, the U-shaped reinforcing plate has a first through hole on its surface, and the diaphragm has a second through hole inside. The U-shaped reinforcing plate and the diaphragm are connected by a second bolt and nut.

[0010] Furthermore, a support plate is installed on the outer surface of the U-shaped reinforcing plate, and the support plate has a triangular structure.

[0011] Furthermore, the fixed connecting rod, sleeve rod, screw rod, and first flange are all arranged coaxially.

[0012] Furthermore, the outer surface of the first flange at the end of the screw begins to have anti-slip texture.

[0013] Furthermore, a second flange is installed at the other end of both the fixed connecting rod and the sleeve rod. Screw holes are opened on both sides of the U-shaped reinforcing plate, and the second flange is installed on the outer surface of the U-shaped reinforcing plate by bolts.

[0014] Furthermore, the outer surfaces of the U-shaped reinforcing plate, the fixed connecting rod, the sleeve rod, and the screw rod are all coated with an anti-corrosion coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, through the setting of U-shaped reinforcing plates, can strengthen the diaphragms, improve their compressive strength, and reduce bending deformation under pressure. Furthermore, through the setting of fixed connecting rods and adjustable connecting rods, adjacent U-shaped reinforcing plates can be connected together to form a coordinated whole structure. The U-shaped reinforcing plates can transfer and share forces with each other, enabling the entire bridge structure to resist external forces more effectively, reducing damage caused by excessive local stress, and allowing the bridge to distribute stress more evenly when bearing loads, avoiding stress concentration, thereby reducing the risk of structural failure.

[0017] 2. This utility model, through the setting of sleeve rod and screw rod, can adjust the length of the entire adjustable connecting rod, thereby adapting to different cross diaphragm spacing and ensuring that two adjacent U-shaped reinforcing plates can be connected as one.

Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-5This utility model provides a reinforcement device for the cross diaphragm of an old bridge, including a U-shaped reinforcement plate 4 and a plurality of parallel web plates 2 disposed on the lower surface of the beam plate 1. A plurality of cross diaphragms 3 are disposed between two adjacent web plates 2. The U-shaped reinforcement plate 4 covers the outer surface of the cross diaphragm 3, and the two sides of the U-shaped reinforcement plate 4 are respectively attached to the web plates 2 on both sides. A fixed connecting rod 5 is installed on one side of the outer surface of the U-shaped reinforcement plate 4, and an adjustable connecting rod 6 is disposed on the other side of the outer surface of the U-shaped reinforcement plate 4. The ends of the fixed connecting rod 5 and the adjustable connecting rod 6 are each equipped with a first flange 7, and the two corresponding first flanges 7 are connected by a first bolt and nut 8.

[0028] In use, the U-shaped reinforcing plate 4 is fitted onto the outside of the transverse diaphragm 3 to provide reinforcement. Then, the first flange 7 at the end of the fixed connecting rod 5 and the first flange 7 at the end of the adjustable connecting rod 6 are connected by the first bolt and nut 8. At this time, two adjacent U-shaped reinforcing plates 4 are connected together to form a cooperating whole structure. The U-shaped reinforcing plates 4 can transfer and share the force with each other, so that the entire bridge structure can resist external forces more effectively, reduce damage caused by excessive local stress, and make the bridge more uniformly distribute stress when bearing load, avoiding stress concentration, thereby reducing the risk of structural failure.

[0029] Preferably, the adjustable connecting rod 6 includes a sleeve rod 61 installed on the outer surface of the U-shaped reinforcing plate 4. The sleeve rod 61 has a threaded groove inside, and a screw rod 62 is inserted into and threadedly connected to the threaded groove. The first flange 7 is installed at the end of the screw rod 62.

[0030] By rotating the screw 62, the extension length can be adjusted under the action of the threaded connection. The length of the entire adjustable connecting rod 6 can be adjusted to match the spacing of the two adjacent transverse partitions 3. After the two first flanges 7 are installed by the first bolt and nut 8, since the fixed connecting rod 5 and the U-shaped reinforcing plate 4 are fixedly connected, the rotation of the screw 62 can be avoided, thus preventing changes in its length and ensuring the reliability of the connection.

[0031] Preferably, the U-shaped reinforcing plate 4 has a first through hole 9 on its surface, and the transverse partition 3 has a second through hole inside. The U-shaped reinforcing plate 4 and the transverse partition 3 are connected by a second bolt and nut 10.

[0032] The U-shaped reinforcing plate 4 is connected to the transverse partition 3 by the second bolt and nut 10, so that the U-shaped reinforcing plate 4 can be stably installed on the transverse partition 3 for reinforcement.

[0033] Preferably, a support plate 11 is installed on the outer surface of the U-shaped reinforcing plate 4, and the support plate 11 has a triangular structure.

[0034] By setting the support plate 11, the contact area between the U-shaped reinforcing plate 4 and the web plate 2 can be increased, and the support strength of the U-shaped reinforcing plate 4 can be improved, giving it a better load-bearing capacity.

[0035] Preferably, the fixed connecting rod 5, sleeve rod 61, screw rod 62 and first flange 7 are all arranged on the same axis.

[0036] When adjusting the length of the adjustable connecting rod 6, the screw 62 needs to be rotated. Since the fixed connecting rod 5, sleeve rod 61, screw 62 and the first flange 7 are all coaxially arranged, the screw 62 can be rotated at a certain angle so that the bolt holes on the two first flanges 7 correspond one-to-one. The two first flanges 7 can be connected together using the first bolt and nut piece 8.

[0037] Preferably, the outer surface of the first flange 7 at the end of the screw 62 has anti-slip texture.

[0038] By using anti-slip textures, operators can rotate the first flange 7 at the end of the adjustable connecting rod 6 to rotate the screw 62 when adjusting the length of the rod. Since the outer surface of the first flange 7 is provided with anti-slip textures, the friction between the first flange 7 and the hand can be increased, reducing the chance of slipping and improving work efficiency.

[0039] Preferably, a second flange 12 is installed at the other end of both the fixed connecting rod 5 and the sleeve rod 61. Screw holes are opened on both sides of the U-shaped reinforcing plate 4. The second flange 12 is installed on the outer surface of the U-shaped reinforcing plate 4 by bolts 13.

[0040] During transportation, the adjustable connecting rod 6 and the fixed connecting rod 5 can be removed from the U-shaped reinforcing plate 4 and transported separately, thereby saving space and improving transportation efficiency. Furthermore, when reinforcing the cross diaphragm 3, they can be installed separately, reducing installation difficulty.

[0041] Preferably, the outer surfaces of the U-shaped reinforcing plate 4, the fixed connecting rod 5, the sleeve rod 61, and the screw rod 62 are all coated with an anti-corrosion coating.

[0042] The application of anti-corrosion coating can improve corrosion resistance, thereby increasing service life and ensuring structural strength and integrity under long-term use. This provides a reliable reinforcement effect for the diaphragm 3 and ensures the safety of the bridge structure.

[0043] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
