Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a reinforcement structure for bridge beams and slabs. Background Technology

[0002] Bridge beams are an important component of bridge structures, primarily used to bear loads from vehicles and pedestrians and transfer them to the piers or abutments. The design and construction quality of the beams directly affect the safety, durability, and performance of the bridge.

[0003] Currently, the most common bridge beams are classified as follows: precast beams, which are manufactured in a prefabrication yard and then transported to the site for installation, such as hollow slabs, T-beams, and box girders; cast-in-place beams, where concrete is poured directly on-site, suitable for bridges with complex shapes or special requirements; and composite beams, which are composed of steel beams and concrete slabs, combining the high strength of steel with the durability of concrete. To improve the load-bearing capacity, stiffness, crack resistance, or durability of bridge beams, reinforcing structures are usually added. However, because bridge beams expand and contract due to environmental influences, conventional reinforcing structures are directly fixed to the bridge beams, which can actually damage the beams during expansion and contraction. Utility Model Content

[0004] In order to solve the technical problems existing in the background art, the present invention provides a reinforcement structure for bridge beams and slabs, which, while ensuring the strengthening of the bridge beam and slab structure, avoids the influence of the expansion and contraction stress of the bridge beam and slab.

[0005] The technical solution adopted by this utility model is:

[0006] A reinforcement structure for bridge beams includes:

[0007] A box girder is installed on the upper end of the foundation pile, and a fixing mechanism is fixedly installed on the side wall of the box girder.

[0008] The fixing mechanisms on two adjacent box girders are set at the same height, and a horizontal tensioning mechanism is snapped between the two fixing mechanisms at the same height. The horizontal tensioning mechanism and the fixing mechanism are slidably connected along the longitudinal direction of the box girder.

[0009] Furthermore, the fixing mechanism includes:

[0010] A fixed base plate is abutted and fixedly installed on the transverse side wall of the box girder. An upper hanging arm and a lower hanging arm are protruding from the upper and lower plates of the fixed base plate. The upper and lower hanging arms are used to lock the transverse pulling mechanism. A side baffle perpendicular to the fixed base plate is provided on one side of the upper and lower hanging arms.

[0011] Furthermore, a set of mounting holes is provided through the fixed base plate, and fixing bolts for fixing and connecting to the transverse side wall of the box girder are inserted into the set of mounting holes.

[0012] Furthermore, a support plate is provided on the other side of the side baffle, which is perpendicular to and fixedly connected to the fixed base plate and the side baffle.

[0013] Furthermore, the lateral pulling mechanism includes:

[0014] Multiple unit boxes are arranged longitudinally along the box girder. Hanging plates are fixedly installed between the unit boxes and at both ends of the longitudinal direction. The hanging plates are clamped on the upper and lower booms.

[0015] Furthermore, the upper boom and lower boom are configured to protrude upwards;

[0016] The two sides of the hanging plate are provided with upper and lower lifting lugs that slide and engage with the upper and lower lifting arms, respectively.

[0017] Furthermore, a connecting box is provided through the center of the hanging plate to enhance the overall rigidity of the horizontal tensioning mechanism.

[0018] Furthermore, the hanging plate is configured as a trapezoid with a wider top and a narrower bottom to prevent the horizontal tensioning mechanism on the fixing mechanism from falling off.

[0019] Furthermore, the side baffles on the fixing mechanisms on both sides of the lateral pulling mechanism are arranged far apart from each other.

[0020] The beneficial effects of this utility model's bridge beam reinforcement structure are as follows:

[0021] The fixed mechanism reliably connects to the box girder; the sliding and snapping cross bracing mechanism on the fixed mechanism ensures the connection strength between the box girders while adapting to the expansion and contraction stress of the box girder. Attached Figure Description

[0032] To more clearly and explicitly illustrate the specific implementation objectives and methods of this utility model, the technical solution of this utility model will be fully described below. The described embodiments are only some embodiments of this utility model, not all embodiments. Without creative effort, all other embodiments based on the described embodiments of this utility model are within the protection scope of this utility model.

[0033] This utility model discloses a reinforcement structure for bridge beams and slabs, such as... Figure 1 , Figure 4 As shown, it includes:

[0034] Box girder 1 is installed on the upper end of the foundation pile.

[0035] A fixing mechanism 2 is fixedly installed on the side wall of the box girder 1, such as... Figure 2 , Figure 4 As shown, it includes:

[0036] A fixed base plate 21 is abutted and fixedly installed on the transverse side wall of the box girder 1. The fixed base plate 21 has a through-hole group 20, and a fixing bolt for fixing and connecting to the transverse side wall of the box girder 1 is inserted in the through-hole group 20. An upper lifting arm 22 and a lower lifting arm 23 are protruding from the upper and lower plates of the fixed base plate 21. The upper lifting arm 22 and the lower lifting arm 23 protrude upward. A side baffle 24 perpendicular to the fixed base plate 21 is provided on one side of the upper lifting arm 22 and the lower lifting arm 23. A support plate 25 perpendicular to the fixed base plate 21 and the side baffle 24 and fixedly connected to the side baffle 24 is provided on the other side of the side baffle 24.

[0037] The fixing mechanisms 2 on two adjacent box girders 1 are set at the same height, and a horizontal tensioning mechanism 3 is installed between the two fixing mechanisms 2 at the same height by means of an upper boom 22 and a lower boom 23. Figure 3 , Figure 4 As shown, it includes:

[0038] Multiple unit boxes 31 are arranged longitudinally along the box girder 1. Hanging plates 32 are fixedly installed between each unit box 31 and at both ends of the longitudinal direction. Each hanging plate 32 is trapezoidal, wider at the top and narrower at the bottom, to prevent the horizontal tensioning mechanism 3 on the fixing mechanism 2 from detaching. The upper and lower ends of the hanging plate 32 protrude from the upper and lower end faces of the unit box 31. Upper lifting lugs that slide and engage with the upper lifting arm 22 are protruding from the lateral sides of the upper protruding plate of the hanging plate 32. Lower lifting lugs that slide and engage with the lower lifting arm 23 are protruding from the lateral sides of the lower protruding plate of the hanging plate 32. The hanging plate 32 is connected by an upper lifting arm. The upper and lower hanging lugs are slidably engaged with the upper and lower hanging arms 22 and 23, respectively, and the horizontal tensioning mechanism 3 slides along the longitudinal direction of the box girder 1 on the fixed mechanism 2. This allows the horizontal tensioning mechanism 3 and the fixed mechanism 2 to slide along the longitudinal direction of the box girder 1 to accommodate the stress generated when the box girder 1 expands and contracts longitudinally. The sliding connection points between the upper hanging lug and the upper hanging arm 22, and between the lower hanging lug and the lower hanging arm 23, are redundantly arranged along the transverse direction of the box girder 1 to accommodate the stress generated when the box girder 1 expands and contracts laterally. A connecting box 33 is provided through the center of the hanging plate 32 to enhance the overall rigidity of the horizontal tensioning mechanism 3.

[0039] The side baffles 24 on the two sides of the horizontal pulling mechanism 3 are set far apart from each other, so that the horizontal pulling mechanism 3 is limited between the side baffles 24 of the two sides of the fixed mechanism 2, preventing the horizontal pulling mechanism 3 from falling from the longitudinal sides of the fixed mechanism 2.

[0040] Based on the specific structure of the bridge beam reinforcement structure in the above embodiments, the reinforcement method will be further explained below:

[0041] A fixing mechanism 2 is reliably fixed on the box girder 1, and a horizontal tensioning mechanism 3 is installed between the two sets of fixing mechanisms 2. The horizontal tensioning mechanism 3 connects multiple box girders 1 to ensure the strength of the fixation between the box girders 1.

[0042] Since the expansion and contraction of box girder 1 are not exactly the same, the expansion and contraction amounts of each box girder 1 are also different, where:

[0043] When the longitudinal expansion and contraction of adjacent box girders 1 are different, the upper lifting lug is slidably engaged with the upper lifting arm 22 and the lower lifting lug is slidably engaged with the lower lifting arm 23, so that the horizontal tensioning mechanism 3 can adapt to the different expansion and contraction between the box girders 1 while ensuring the stable connection between the box girders 1.

[0044] When the lateral expansion and contraction of adjacent box girders 1 are different, the lateral redundant sliding between the upper lifting lug and the upper lifting arm 22, and between the lower lifting lug and the lower lifting arm 23, allows the lateral tensioning mechanism 3 to reduce the lateral offset of the box girder 1 while ensuring the stable connection of the fixing mechanism 2.

[0045] In summary, the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
