Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically to a steel structure for reinforcing concrete beams. Background Technology

[0002] Concrete beams are mainly supported by steel bars, with plates fixed around them to form an upward-facing pouring opening. Concrete is poured into the pouring opening to contact the steel bars, and after natural air drying, it forms an independent beam. It is the main load-bearing component in bridge construction.

[0003] During the construction of bridges, after long-term use, problems such as rusting of internal steel bars and concrete damage due to environmental temperature differences or insufficient reinforcement may occur, leading to cracks on the bridge's interior or surface. This necessitates reinforcement of the bridge. Common reinforcement methods include filling the cracks with concrete or epoxy cement. However, the effectiveness of this method is limited. Because the original structure has already undergone strain, over a long period, the secondary stress at the cracks will gradually increase downwards, eventually causing complete damage to the overall bridge structure and affecting its service life. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned problems in the existing technology.

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0027] like Figure 1-5 As shown, a steel structure for reinforcing a concrete beam includes a pier 3 and a bridge deck 1 mounted on the pier 3, and further includes:

[0028] Support sleeve 4 is installed on pier 3, and a reinforcing rod 5 is installed on support sleeve 4. The reinforcing rod 5 is attached to bridge deck 1.

[0029] The reinforcement unit 6 is arranged in a linear array on the reinforcement rod 5. The linear array here specifically refers to the arrangement of several reinforcement units 6 along the reinforcement rod 5, and the several reinforcement units 6 are arranged sequentially along the length of the reinforcement rod 5. The reinforcement unit 6 includes a push rod 66, a support frame 64, and a screw 63 rotatably connected to the support frame 64. A slider 65 is threadedly connected to the screw 63.

[0030] One end of the push rod 66 is engaged with the slider 65, while the other end is provided with a push plate 62 that fits against the bridge surface 1.

[0031] Specifically, a bridge 2 is installed on the pier 3, and the bridge deck 1 is fixed to the bridge 2. The support sleeve 4 is installed on the pier 3 and fits against the bridge 2 to support the bridge 2. The reinforcing rod 5 is fixed to the support sleeve 4 and fits against the bottom surface of the bridge deck 1 to provide a certain support effect to the bridge deck 1. Then, a reinforcing unit 6 is installed on the reinforcing rod 5. The reinforcing unit 6 is installed under the crack of the bridge deck 1. By rotating the screw 63, the two sliders 65 slide relative to each other, causing the push rod 66 to drive the push plate 62 to fit against the bridge deck 1 to give it a certain compressive force and improve the support effect of the bridge deck 1. Furthermore, multiple sets of reinforcing units 6 can be evenly distributed on the reinforcing rod 5 to improve the overall stability of the bridge deck 1.

[0032] As a further embodiment of this utility model, the push plate 62 is provided with a bonding pad 61, which is a shock-absorbing pad. The shock-absorbing pad improves the support effect of the reinforcement unit 6 on the bridge deck 1, and can also absorb and disperse the vibration energy generated by the bridge deck 1 through its elastic properties, thereby reducing the transmission of vibration of the bridge deck 1 to the reinforcement unit 6.

[0033] As a further embodiment provided by this utility model, the reinforcing rod 5 has a first supporting surface 51 and a second supporting surface 52. The area of ​​the first supporting surface 51 is larger than that of the second supporting surface 52. The first supporting surface 51 is in contact with the bridge deck 1. The support frame 64 cooperates with the second supporting surface 52. The first supporting surface 51 is in contact with the outer wall of the bridge deck 1 to provide a certain support effect to the bottom of the bridge deck 1. The support frame 64 can move on the supporting surface to adjust the position of the reinforcing unit 6. Bolt holes are provided on the support frame 64, and the reinforcing unit 6 can be locked through the bolt holes.

[0034] As a further embodiment provided by this utility model, the reinforcing rod 5 is provided with a connecting part 54, and a reinforcing plate 53 is provided at the connecting part 54. The reinforcing rod 5 is composed of multiple steel beams, which facilitates the assembly of the reinforcing rod 5 to the bottom of the bridge deck 1. The connecting part 54 is formed by the bonding and connection of two adjacent steel beams. The connection effect of adjacent steel beams is improved by installing the reinforcing plate 53.

[0035] As a further embodiment of this utility model, a fixing groove 41 is provided on the support sleeve 4, and a support plate 42 is provided on the fixing groove 41. The support plate 42 is provided with a third crossbeam 46 for supporting the reinforcing rod 5. The support plate 42 is fixed to the fixing groove 41 by bolts. When the support plate 42 is installed and fixed, one side of the support plate 42 will fit against the bridge 2 to improve the overall stability of the parts on the support sleeve 4.

[0036] As a further embodiment of this utility model, a second crossbeam 45 is provided on the support plate 42. A groove 451 is provided on the second crossbeam 45. A connecting rod 43 is rotatably arranged in the groove 451. A support seat 44 that cooperates with the reinforcing rod 5 is provided on the connecting rod 43. The number of support seats 44 is the same as that of the reinforcing rod 5. The number of grooves 451, connecting rods 43 and support seats 44 is the same. When the reinforcing rod 5 is fixed to the third crossbeam 46, the connecting rod 43 is assembled in the groove 451 so that the support seat 44 on the connecting rod 43 is connected to the lower plane of the reinforcing rod 5, thereby improving the support effect of the reinforcing rod 5 and further improving the fit between the reinforcing rod 5 and the bridge deck 1.

[0037] As a further embodiment provided by this utility model, the support sleeve 4 is provided with reinforcing ribs, and the support sleeve 4 is provided with multiple sets of reinforcing ribs, which improves the support effect of the support sleeve 4, and the support is composed of two semi-circular rings (e.g. Figure 4 As shown, the semi-circular ring sleeve is integrally formed and has multiple mounting holes on its surface. One type of mounting hole connects two semi-circular ring sleeves to fix the support sleeve 4 to the pier 3, and the other type connects to the bridge 2 to provide a certain support effect for the bridge 2.

[0038] As a further embodiment of this utility model, a first crossbeam 40 is provided on the support sleeve 4. The first crossbeam 40 is located between two parallel support sleeves 4 and is used to reinforce the two support sleeves 4.

[0039] As a further embodiment provided by this utility model, at least three sets of reinforcement units 6 are provided, and the three sets of reinforcement units 6 are evenly distributed on the reinforcement rod 5. In addition to being installed under the crack, multiple sets of reinforcement units 6 can also be provided on the reinforcement rod 5, and the reinforcement units 6 are evenly distributed. Multiple reinforcement units 6 provide support to improve the support effect on the bridge deck 1.

[0040] Working principle: First, the support sleeve 4 is fitted onto the pier 3 and fixed with bolts. Then, the first crossbeam 40 and the support plate 42 are assembled on the support sleeve 4 in sequence. The support plate 42 reinforces the two parallel support sleeves 4. The support plate 42 is used to install the second crossbeam 45 and the third crossbeam 46. The reinforcing rod 5 is assembled on the third crossbeam 46. According to the cracking state of the bridge deck 1, the reinforcing unit 6 can be installed at the bottom of the crack. The screw 63 is rotated so that the two sliders 65 slide relative to each other on the support frame 64. The pusher 66 drives the push plate 62 to move upward and make the push plate 62 fit against the outer wall of the bridge deck 1 to give the bridge deck 1 a certain pre-pressure, which improves the support effect of the bridge deck 1 and extends the service life of the bridge deck 1.
