[0002] Steel bridges are primarily constructed of steel, characterized by high strength and rigidity, while reducing beam height and deadweight compared to concrete bridges. Conventional bridge beam installation typically involves cutting the overall steel beam into smaller pieces and hoisting them onto piers for welding and assembly. Due to the small contact surface of individual piers, corbels are often constructed on the piers to support the hoisted beam segments, which are then welded together. However, the corbels have limited load-bearing capacity, and excessive loads can lead to structural instability. Furthermore, the installation and removal of the corbels can damage the pier connections, creating cracks and posing a safety hazard. Utility Model Content

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the present invention proposes a single pier load-bearing support, which is installed on the pier 1 and includes:

[0024] Support plates 2, two support plates 2 are distributed in mirror image on the top of the pier 1 and respectively abut against both sides of the support of the pier 1;

[0025] A fixing assembly, comprising two fixing plates 3 slidably disposed at both ends of the support plate 2 and an adjusting member rotatably disposed on the support plate 2, the adjusting member being connected to the two fixing plates 3 and configured to drive the two fixing plates 3 toward each other and respectively abut against the sides of the pier 1 to fix the support plate 2; and

[0026] The connecting assembly is provided between the two support plates 2 and is used to connect the two support plates 2 .

[0027] In the embodiment of the present invention, when assembling the load-bearing bracket, the two support plates 2 are respectively erected on the top of the pier 1, and the two support plates 2 are respectively located on both sides of the support. In order to facilitate the installation of the support plates 2, the distance between the two fixing plates 3 in the initial state is larger than the pier 1, so the two fixing plates 3 at the bottom of the support plate 2 can be brought close to each other directly through the action of the adjusting member. Among them, when one of the fixing plates 3 is in contact with the pier 1 and the other fixing plate 3 is not in contact, the two fixing plates 3 can be made to contact the pier 1 under the continuous movement of the adjusting member, which not only completes the clamping and fixing of the support plate 2 on the pier 1, but also completes the centering adjustment of the support plate 2 to ensure its normal use. After the installation is completed, the bridge steel beam components can be directly erected on the support plate 2, and the gravity received can be directly transferred to the top of the pier 1 through the support plate 2, which can effectively disperse the weight and better support the bridge steel beam components and the formed bridge steel beam. Compared with the transmitted corbel support, the stability of the support for the bridge steel beam components and the formed bridge steel beam is improved, and the non-destructive installation and disassembly of the two support plates 2 will not cause damage to the pier 1, thereby ensuring the quality of the bridge construction.

[0028] Secondly, with the cooperation of the connecting assembly, when the two support plates 2 are installed on the top of the pier 1, the two support plates 2 can be tightened and connected through the connecting assembly, which not only avoids the lateral position of the support plates 2 after installation, but also facilitates disassembly after use.

[0029] Based on the above scheme, if Figure 3 As shown, the adjusting member includes an adjusting rod 4 rotatably arranged on the support plate 2 and two driving blocks 402 slidably arranged on the support plate 2, the two driving blocks 402 are respectively connected to the two fixed plates 3, the adjusting rod 4 is arranged on the first thread segment 401 corresponding to the two driving blocks 402, and the driving blocks 402 are engaged with the first thread segment 401.

[0030] Specifically, when the two fixed plates 3 are adjusted by the action of the adjusting member, the adjusting rod 4 is rotated to drive the first threaded segment 401 provided thereon to rotate, and the rotation directions of the two first threaded segments 401 are opposite, so when the adjusting rod 4 is rotated, the two driving blocks 402 can be driven to move away from or towards each other. When the two driving blocks 402 move towards each other, the two fixed plates 3 move towards each other, thereby abutting against the bridge pier 1. When the two driving blocks 402 move away from each other, the fixed plate 3 is separated from the bridge pier 1, thereby facilitating disassembly.

[0031] Based on the above scheme, if Figure 4 As shown, the connecting assembly includes a connecting frame 6 provided on one of the support plates 2 and a connecting rod 5 provided on the other support plate 2. The end of the connecting rod 5 is clamped on the connecting frame 6, and the end of the connecting rod 5 is provided with a second threaded segment 501. The second threaded segment 501 is threadedly connected to a nut 502, and the nut 502 abuts against one end of the connecting frame 6.

[0032] Specifically, when the two support plates 2 are connected by the action of the connecting assembly, the step of connecting the two support plates 2 is before rotating the adjusting rod 4. When the two support plates 2 are both at the top of the pier 1, the connecting rod 5 on one of the support plates 2 is clamped on the connecting frame 6 on the other support plate 2. The connecting frame 6 has a notch to provide an installation position for the connecting rod 5. Finally, the nut 502 is screwed on the second threaded section 501 until it abuts against the end of the connecting frame 6 to complete the connection between the connecting rod 5 and the connecting frame 6, so that the two support plates 2 abut against the side of the support, which can facilitate the lateral displacement of the support plates 2.

[0033] Specifically, such as Figure 4 As shown, the connecting frame 6 and the connecting rod 5 are respectively rotatably arranged on the two support plates 2; so that the connecting frame 6 can be rotated after being separated from the connecting rod 5 and stored on the side of the support plate 2, thereby reducing the body size to a certain extent, making it convenient to store the support plate 2 when not in use and convenient for transportation.

[0034] Specifically, such as Figure 1As shown, a support rod 301 is fixed to the side of the fixing plate 3, and the end of the support rod 301 abuts against the bottom of the support plate 2; specifically, the support rod 301 extends from the fixing plate 3 to the bottom of the support plate 2, forming a triangular support structure, which can provide additional support to prevent the fixing plate 3 from being displaced or deformed when subjected to external force, thereby enhancing the rigidity and stability of the entire bracket system, and can better distribute and transfer the load, ensuring that even under heavy load conditions, the support plate 2 can remain stable and will not be deformed or damaged due to excessive local pressure.

[0035] Specifically, such as Figure 1 As shown, a slide groove 202 is provided on the side of the support plate 2, and a slider 302 is slidingly provided in the slide groove 202, and the slider 302 is connected to the end of the support rod 301; the connection between the slider 302 and the support rod 301 can ensure that the fixed plate 3 is always in the optimal support state, and ensure that the support rod 301 is always at the bottom of the support plate 2.

[0036] Specifically, such as Figure 1 As shown, both ends of the support plate 2 are provided with a limiting portion 201, which can limit the bridge steel beam erected on the support plate 2 to avoid side sliding.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
