Description
Technical Field
[0001] This utility model relates to a support bracket for bridge construction, and in particular to a support bracket for bridge construction, belonging to the technical field of support brackets. Background Technology
[0002] In bridge construction, support brackets are key temporary load-bearing equipment for core processes such as the installation of cast-in-place beams and precast beams. Their performance directly affects construction efficiency, structural accuracy, and operational safety. Current bridge construction scenarios are characterized by diverse structural forms (such as continuous beams, T-beams, and box girders), complex construction environments (such as crossing roads, rivers, and high-altitude operations), and variable load requirements (requiring support for formwork, concrete, construction machinery, and personnel weight). These characteristics place stringent demands on the adaptability, stability, and safety of support brackets.
[0003] Traditional bridge construction uses fixed support brackets, typically at a fixed height. However, the core drawback of fixed-height bridge construction support brackets is their inability to adapt to dynamic changes in the construction environment. They cannot handle the height differences between different parts of the bridge. Bridge construction involves multiple structures such as piers, cap beams, and beams, each requiring significantly different support heights. With fixed brackets, one set of equipment can only correspond to one construction stage or a specific height, necessitating frequent purchases and replacements of brackets of different specifications. This significantly increases equipment costs and storage pressure. Furthermore, it makes it difficult to achieve a precise fit between the support brackets and the bridge structure. There may be slight dimensional deviations at the bottom of the bridge structure, and fixed brackets cannot be fine-tuned to fit the structural surface, easily creating support gaps. This can cause platform swaying during construction, affecting the accuracy of processes such as rebar tying and formwork installation.
[0004] Therefore, there is an urgent need to improve a support bracket for bridge construction in order to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this utility model is to provide a support bracket for bridge construction. By setting up a lifting and adjusting structure, it changes the traditional fixed-height connection method of the support bracket body, so that the support bracket body can fully adapt to the dynamic changes of the construction scene and cope with the height difference of different parts of the bridge. The advantage of this structure is that it can achieve precise control of the support height of the support bracket body, adapt to the height difference requirements of different parts of the bridge such as piers, cap beams, and beams, and eliminate the need for frequent replacement of different specifications of brackets, which greatly reduces equipment procurement costs and warehousing pressure. At the same time, the rubber pad on the top of the support bracket body can increase the friction with the bridge structure, buffer the vibration during construction, reduce the support gap, prevent platform swaying, and ensure the accuracy of processes such as rebar binding and formwork installation.
[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include: A support bracket for bridge construction includes a base plate and a support bracket body. The base plate is equipped with a lifting and adjusting structure, which includes several upright plates fixedly installed on the top of the base plate. A connecting plate is fixedly installed on the outer side of each upright plate, and a connecting block is fixedly installed on the inner side of each connecting plate. A lead screw connected to the upright plate is movably installed on the connecting block, and a transmission block is installed on the lead screw. A first support plate connected to the support bracket body is installed at one end of the transmission block, and a first helical gear is fixedly installed at one end of the lead screw. Several drive motors are fixedly installed on the base plate, and a second helical gear meshing with the first helical gear is fixedly installed at the output end of each drive motor. Several rubber pads are fixedly installed on the top of the support bracket body.
[0007] Preferably, a protective shell is fixedly installed on the outside of the drive motor, the protective shell has a plurality of heat dissipation holes, and a maintenance cover is provided at one end of the protective shell.
[0008] Preferably, a first magnetic ring is fixedly installed at the bottom of the inspection cover, and a second magnetic ring that is magnetically connected to the first magnetic ring is fixedly installed at the top of the protective shell.
[0009] Preferably, slide rails are fixedly installed at both ends of the upright plate, and a slider connected to the slide rails is fixedly installed on the inner side of the first support plate.
[0010] Preferably, a plurality of fixed frames are fixedly installed on both sides of the base plate, a fixed bracket is fixedly installed on the top of the fixed frame, an electric telescopic rod is fixedly installed on the bottom of the fixed bracket, and a second support plate is installed on the output end of the electric telescopic rod.
[0011] Preferably, a fixing block is fixedly installed on the electric telescopic rod, and a fixing sleeve connected to the fixing block is fixedly installed on the top of the second support plate. Both the fixing block and the fixing sleeve have connecting holes, and a plug is movably installed inside the connecting hole. One end of the plug is fixedly installed with a latch.
[0012] Preferably, a plurality of protrusions are fixedly installed at the other end of the insertion rod, and a plurality of rake teeth are fixedly installed at the bottom of the second support plate.
[0013] This utility model has at least the following beneficial effects: By incorporating a lifting and adjusting structure, the traditional fixed-height connection method of the support bracket body is changed. This allows the support bracket body to fully adapt to dynamic changes in the construction scenario and cope with height differences in different parts of the bridge. The advantage of this structure is that it enables precise control of the support height of the support bracket body, adapting to the height difference requirements of different parts of the bridge, such as piers, cap beams, and beams. It eliminates the need for frequent replacement of different specifications of brackets, significantly reducing equipment procurement costs and warehousing pressure. At the same time, the rubber pad on the top of the support bracket body increases the friction with the bridge structure, while buffering vibrations during construction, reducing support gaps, preventing platform swaying, and ensuring the accuracy of processes such as rebar tying and formwork installation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-5 As shown in the figure, this embodiment provides a support bracket embodiment for bridge construction.
[0018] A support bracket for bridge construction includes a base plate 1 and a support bracket body 2. The base plate 1 is provided with a lifting and adjusting structure 3. The lifting and adjusting structure 3 includes several upright plates 4 fixedly installed on the top of the base plate 1. A connecting plate 5 is fixedly installed on the outer side of the upright plate 4. A connecting block 6 is fixedly installed on the inner side of the connecting plate 5. A lead screw 7 connected to the upright plate 4 is movably installed on the connecting block 6. A transmission block 8 is installed on the lead screw 7. A first support plate 9 connected to the support bracket body 2 is installed at one end of the transmission block 8. A first helical gear 10 is fixedly installed at one end of the lead screw 7. Several drive motors 11 are fixedly installed on the base plate 1. A second helical gear 12 meshing with the first helical gear 10 is fixedly installed at the output end of the drive motor 11. Several rubber pads are fixedly installed on the top of the support bracket body 2. By setting up the lifting and adjusting structure 3, the traditional fixed-height connection method of the support bracket body 2 is changed, so that the support bracket body 2 can fully adapt to the dynamic changes of the construction scene and cope with the height difference of different parts of the bridge. The base plate 1 is placed at the designated support position of the bridge construction to ensure that the bottom of the base plate 1 is in stable contact with the ground or foundation structure, serving as the load-bearing foundation of the entire support bracket. The support bracket body 2 is initially in the state to be adjusted, and its top rubber pad is not yet in contact with the part of the bridge to be supported. Several drive motors 11 fixedly installed on the base plate 1 are started. The output end of the drive motor 11 drives the second helical gear 12 fixedly connected to it to rotate. Since the second helical gear 12 meshes with the first helical gear 10 fixedly installed at one end of the lead screw 7, the rotational power of the second helical gear 12 is transmitted to the first helical gear 10, thereby driving the lead screw 7 to rotate synchronously. The lead screw 7 is movably installed on the connecting The connecting block 6 is connected to the upright plate 4 fixed on the top of the base plate 1. When the lead screw 7 rotates, it undergoes axial displacement along the movement trajectory of the connecting block 6. The transmission block 8 installed on the lead screw 7 moves synchronously with the displacement of the lead screw 7. The first support plate 9 connected to one end of the transmission block 8 drives the support bracket body 2 to move up and down until the rubber pad on the top of the support bracket body 2 is tightly fitted with the part of the bridge to be supported, thus completing the adjustment of the support height. The advantage of this structure is that it can achieve precise control of the support height of the support bracket body 2, which can adapt to the height difference requirements of different parts of the bridge piers, cap beams, beams, etc. It eliminates the need to frequently replace different specifications of brackets, greatly reducing equipment procurement costs and warehousing pressure. At the same time, the rubber pad on the top of the support bracket body 2 can increase the friction with the bridge structure, while buffering the vibration during construction, reducing the support gap, preventing platform swaying, and ensuring the accuracy of processes such as rebar binding and formwork installation.
[0019] like Figures 1-5As shown, with the protective shell 13, heat dissipation holes 14, and inspection cover 15, when the drive motor 11 is running, the protective shell 13 fixedly installed on its outside provides physical protection for the drive motor 11, preventing dust, sand, rainwater, and other impurities from directly contacting the internal components of the drive motor 11 during construction. The heat dissipation holes 14 on the protective shell 13 can dissipate the heat generated by the drive motor 11 in a timely manner, preventing the drive motor 11 from degrading or being damaged due to overheating. When it is necessary to inspect or maintain the drive motor 11, the inspection cover 15 set at one end of the protective shell 13 can be opened to conveniently inspect, repair, or replace parts of the drive motor 11.
[0020] like Figures 1-5 As shown, with the arrangement of the first magnetic ring 16 and the second magnetic ring 17, when the maintenance cover 15 is closed, the first magnetic ring 16 fixedly installed at the bottom of the maintenance cover 15 and the second magnetic ring 17 fixedly installed at the top of the protective shell 13 approach each other. Due to magnetic attraction, the first magnetic ring 16 and the second magnetic ring 17 are tightly attracted, so that the maintenance cover 15 is firmly covered on the protective shell 13. When it is necessary to open the maintenance cover 15, a certain external force is applied to overcome the magnetic force between the first magnetic ring 16 and the second magnetic ring 17, and the maintenance cover 15 can be removed from the protective shell 13. There is no need to use screws, clips or other complex connecting parts. The opening and closing of the maintenance cover 15 can be realized by magnetic attraction, which simplifies the operation steps of the maintenance cover 15, saves the time of opening and closing the maintenance cover 15 during maintenance, and improves the efficiency of equipment maintenance.
[0021] like Figures 1-5 As shown, through the setting of slide rail 18 and slider 19, during the up and down movement of the support bracket body 2 with the first support plate 9, the slide rail 18 fixedly installed at both ends of the upright plate 4 and the slider 19 fixedly installed on the inner side of the first support plate 9 always remain connected. The slider 19 slides synchronously along the track of slide rail 18, providing guidance for the up and down movement of the first support plate 9, ensuring that the first support plate 9 drives the support bracket body 2 to move and always maintain horizontal stability without lateral deviation or tilting. The cooperation of slide rail 18 and slider 19 limits the movement trajectory of the first support plate 9 and the support bracket body 2, avoiding deviation or tilting of the support bracket body 2 during height adjustment, ensuring that the rubber pad on the top of the support bracket body 2 can accurately fit with the part of the bridge to be supported, and further improving the support accuracy.
[0022] like Figures 1-5As shown, through the setting of fixed frame 20, fixed bracket 21, electric telescopic rod 22 and second support plate 23, before the main body of the support bracket 2 is put into use, according to the flatness of the construction site and the requirements of support stability, several electric telescopic rods 22 fixedly installed on both sides of the base plate 1 are activated; the output end of the electric telescopic rod 22 drives the second support plate 23 connected to it to move up and down, adjust the height of the second support plate 23, so that the bottom of all the second support plates 23 are in close contact with the ground, forming auxiliary support for the base plate 1; the electric telescopic rod 22 is fixed by the fixed bracket 21 fixed on the top of the fixed frame 20, ensuring that the electric telescopic rod 22 remains stable during operation and support, without shaking or displacement. The second support plates 23 on both sides of the base plate 1 form auxiliary support points, which together with the bottom of the base plate 1 form a multi-point support structure, dispersing the pressure of the entire support bracket and bridge load on the ground, reducing the risk of tilting and settlement of the base plate 1 due to uneven ground force, and ensuring construction safety.
[0023] like Figures 1-5 As shown, with the setting of fixing block 24, fixing sleeve 25, connecting hole 26, insert rod 27 and latch 28, after the electric telescopic rod 22 drives the second support plate 23 to adjust to the specified height, the fixing block 24 fixedly installed on the electric telescopic rod 22 and the fixing sleeve 25 fixedly installed on the top of the second support plate 23 are aligned. At this time, insert rod 27 is inserted into the connecting hole 26 opened on both fixing block 24 and fixing sleeve 25, so that fixing block 24 and fixing sleeve 25 are connected and fixed through insert rod 27; then, the latch 28 fixedly installed at one end of insert rod 27 is rotated to a state perpendicular to insert rod 27, and the latch 28 is locked on the outside of fixing sleeve 25 to prevent insert rod 27 from falling out of connecting hole 26, thereby locking the relative position of electric telescopic rod 22 and second support plate 23. Unlocking is done by reversing the operation. No complicated tools are required, which makes it easy for construction personnel to quickly complete the locking or unlocking operation without affecting the construction progress.
[0024] like Figures 1-5 As shown, by setting the protrusions 29 and rake teeth 30, the several protrusions 29 fixedly installed on the other end of the insertion rod 27 can increase the friction between the hand and the insertion rod 27, making it easier for construction personnel to hold the insertion rod 27 for insertion and removal operations, and avoiding the insertion rod 27 from slipping due to hand slippage or not being inserted in place. When the second support plate 23 contacts the ground, the several rake teeth 30 fixedly installed on the bottom of the second support plate 23 insert into the ground soil or gravel, enhancing the grip of the second support plate 23 on the ground, preventing the second support plate 23 from sliding during the support process, thereby enhancing the anti-slip ability of the entire support bracket body 2 and reducing construction safety risks.
[0025] In this embodiment, as Figures 1-5 As shown in the figure, the working process of a bridge construction support bracket provided in this embodiment is as follows: The base plate 1 is placed at the designated support position for bridge construction, ensuring that the bottom of the base plate 1 is in stable contact with the ground or foundation structure, serving as the load-bearing foundation for the entire support bracket. The support bracket body 2 is initially in an adjustment-ready state, with its top rubber pad not yet in contact with the bridge section to be supported. Several drive motors 11 fixedly installed on the base plate 1 are started, and the output end of the drive motor 11 drives the second helical gear 12 fixedly connected to it to rotate. Since the second helical gear 12 meshes with the first helical gear 10 fixedly installed at one end of the lead screw 7, the rotational power of the second helical gear 12 is transmitted to the first helical gear 10, thereby driving the lead screw 7 to rotate synchronously. The lead screw 7 is movably installed on the connecting block 6 and connected to the vertical plate 4 fixed on the top of the base plate 1. When the lead screw 7 rotates, it undergoes axial displacement along the movement trajectory of the connecting block 6. The transmission block 8 installed on the lead screw 7 moves synchronously with the displacement of the lead screw 7, and the first support plate 9 connected to one end of the transmission block 8 drives the support bracket body 2 to move up and down until the rubber pad at the top of the support bracket body 2 is tightly fitted with the bridge section to be supported, completing the support height adjustment.
[0026] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
