[0002] With the increasing number of bridges being erected, the demand for bridge support brackets during bridge construction is also increasing. Currently, most common brackets are installed during construction using multiple independent components, such as supports, bolts, and nuts. After the bridge is built, they are either directly fixed to the bridge structure as a support structure or disassembled and recycled. This results in limited functionality of existing brackets, which cannot effectively meet the needs of use. When fixed to the bridge structure, the bolts and nuts of the brackets are prone to stripping and loosening during long-term use, resulting in poor support for the bridge structure. When disassembling and recycling, the integrated supports arranged along the length of the bridge structure are not convenient for disassembly and recycling. Therefore, there is an urgent need for a new type of bridge support bracket to solve the above problems. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example: Refer to Figures 1-3 A bridge support bracket for bridge construction includes a pair of base plates 1, which are configured to be fastened to a bridge pier 18 by a tensioning member, and the two ends of the tensioning member are detachably connected to the pair of base plates 1 respectively.

[0033] The top of the base plate 1 is rotatably fitted with a top plate 2, and a support is provided between the top plate 2 and the base plate 1. The top plate 2 and the base plate 1 respectively abut against the bottom surface of the bridge body 19 and the bridge pier 18.

[0034] The pre-tightening assembly includes a first pre-tightening member disposed on the base plate 1 and a second pre-tightening member disposed on the top plate 2;

[0035] Among them, a pair of pretensioners located on a pair of base plates 1 are configured to provide prestress in the opposite direction to the tensioner, and a pair of second pretensioners abut against the pier 18 respectively. The second pretensioners are configured to cooperate with the support to form a force applied to the top plate 2 in the opposite direction.

[0036] This invention disassembles the overall support bracket structure, using a pair of base plates 1 interlocked and fixed to the bridge pier 18. A tensioning member is placed between the base plates 1, providing an external force to pull and fix the base plates 1 in a direction of mutual approach. Simultaneously, a support member secures the top plate 2, which rotatably fits onto the base plates 1, against the bridge body 19. This forms a bidirectional support that fits snugly against the bridge structure. This not only effectively improves the convenience of disassembling and installing the bracket structure, but also, when the support bracket is used for long-term fixation to the bridge, the first and second pre-tensioning members apply prestress in the opposite direction to the base plates 1 as they abut against the bridge pier 18, maintaining connection stability and strength. Furthermore, the second pre-tensioning member, in conjunction with the support member, creates a bidirectional force on the top plate 2 as it abuts against the bridge body 19, further enhancing the stability of the overall support bracket connection to the bridge and ensuring improved performance of the support bracket under long-term support.

[0037] Furthermore, the first pre-tightening component includes a first pressure plate 3. A groove is provided on the side of the base plate 1 near the pier 18. The first pressure plate 3 is slidably connected in the groove. A plurality of first springs 4 are provided between the first pressure plate 3 and the inner wall of the bottom end of the groove. The two ends of the first springs 4 are respectively fixed to the first pressure plate 3 and the base plate 1.

[0038] Furthermore, a first contact pad 5 is fixedly connected to the side of the first pressure plate 3 near the pier 18.

[0039] By creating a groove on the side of the base plate 1 near the pier 18, the first pressure plate 3, the first spring 4, and the first contact pad 5 are placed in the groove. The first spring 4 supports the first pressure plate 3 so that the first contact pad 5 abuts against the pier 18. Thus, when a pair of base plates 1 are fastened together, the pair of first pressure plates 3 can generate prestress relative to the base plate 1. Under the action of the tensioning member, the connection stability between the base plate 1 and the pier 18 is effectively improved.

[0040] Furthermore, baffles are fixed to both ends of the groove to seal the groove, thereby protecting the first spring 4, extending its service life, and providing long-lasting prestress.

[0041] Furthermore, the second pre-tightening component includes a second pressure plate 6. A pair of second pressure plates 6 are respectively provided on the adjacent sides of a pair of top plates 2. A threaded groove is opened in the top plate 2, and an adjusting screw 20 is threadedly connected in the threaded groove. One end of the adjusting screw 20 extends out of the threaded groove and is rotatably fixed to the second pressure plate 6.

[0042] Furthermore, the second pretensioner also includes a second spring 7, the two ends of which are fixedly connected to the top plate 2 and the second pressure plate 6, respectively.

[0043] The second pressure plate 6 is fixedly connected to the side away from the second spring 7 with a second contact pad 8, and the top surface of the top plate 2 is fixedly connected to a third contact pad 9.

[0044] When the supporting member rotates the top plate 2 relative to the base plate 1 until it abuts against the bottom surface of the bridge body 19, the adjusting screw 20 is rotated, and the second pressure plate 6 is rotatably fixed to the adjusting screw 20 through the bearing. Under the action of the thread, the second pressure plate 6 moves along the side wall of the adjacent pier 18 until the second contact pad 8 abuts against the side wall of the pier 18, thereby realizing the prestress applied to the top plate 2. Under the supporting and fixing action of the supporting member on the top plate 2, the fixing effect between the top plate 2 and the bridge is improved. At the same time, while the supporting member is supporting and fixing the top plate 2, the third connection... The pad layer 9 abuts against the bottom surface of the bridge body 19. In addition, the reverse prestress applied to the top plate 2 by the second spring 7 and the second pressure plate 6 is directly transmitted to the side of the substrate 1 away from the first pressure plate 3 through the support member, thereby completing the support prestress in at least three directions for the substrate 1. During the long-term use of the substrate 1, the prestress can effectively ensure the stability of the overall support bracket and the bridge connection, and can also provide assistance when the substrate 1 is disassembled, avoiding the situation where the support bracket is difficult to disassemble due to structural corrosion and adhesion, thus realizing convenient disassembly and use by personnel.

[0045] Furthermore, a sleeve 10 is integrally formed on the side of the base plate 1 away from the pier 18. A connecting plate 11 is slidably fitted inside the sleeve 10. The top end of the connecting plate 11 extends out of the sleeve 10 and is hinged to the top plate 2. The two ends of the support member are connected to the sleeve 10 and the top plate 2 respectively.

[0046] In one embodiment of the present invention, a toothed groove 12 is provided on the connecting plate 11, and a ratchet tooth (not shown in the figure) that meshes with the toothed groove 12 is fixedly connected inside the sleeve 10, so that the connecting plate 11 can slide along the sleeve 10 toward the bridge body 19, and is fixed when it slides to abut against the bridge body 19. A top plate 2 is hinged to the top of the connecting plate 11, so that the top plate 2 and the connecting plate 11 cooperate to form an L-shaped support structure, which effectively enhances the supporting effect of the top plate 2 on the bridge body 19.

[0047] Furthermore, the support component is a jack 13, and the bottom surface of the top plate 2 and the outer wall surface of the sleeve 10 are respectively fixed to a fixed seat 14, and the two ends of the jack 13 are respectively hinged to the two fixed seats 14.

[0048] In this technical solution, the jack 13 is a common threaded jack 13. By activating the jack 13 during installation, the top plate 2 is supported. The two ends of the jack 13 are respectively hinged to the fixed seat 14 to ensure the supporting effect on the top plate 2 and effectively improve the supporting strength.

[0049] Furthermore, the tensioning element includes at least one pair of threaded tensioners 15, and a pair of threaded sleeves 16 are fixedly connected to both sides of the base plate 1. Any one of the pair of threaded tensioners 15 is threadedly connected to the two threaded sleeves 16 arranged opposite to each other on the same side, and a locking mechanism is threadedly fitted on the end of the threaded tensioner 15 connected to the threaded sleeve 16.

[0050] The locking mechanism is a common locking nut 17. By threading the two ends of the thread tensioner 15 to the two oppositely arranged threaded sleeves 16, the pair of base plates 1 can be fastened and fixed by turning the thread tensioner 15. The threaded sleeves 16 are respectively provided on both sides of the base plate 1 to improve the stability of the fastening and fixing of the pair of base plates 1 and ensure the support function. After the thread tensioner 15 is tightened, the locking nut 17 is turned in the opposite direction to make the locking nut 17 abut against the adjacent threaded sleeve 16, thus completing the locking and fixing of the thread tensioner 15.

[0051] A method for using a bridge support bracket for bridge construction, characterized by comprising the following steps:

[0052] First, slide the connecting plate 11 into the sleeve 10 and move the base plate 1 to the support position;

[0053] The pair of base plates 1 are fastened together and the threaded tensioner 15 is rotated until the first contact pad 5 abuts against the pier 18;

[0054] Then the thread tensioner 15 is locked to the threaded sleeve 16 by the locking mechanism;

[0055] The top plate 2 is lifted by rotating the jack 13 and placed against the bridge body 19;

[0056] Rotate the adjusting screw 20 until the second contact pad 8 abuts against the adjacent pier 18.

[0057] Furthermore, when the connecting plate 11 is slid into the sleeve 10 and the base plate 1 is moved to the support position, the top plate 2 is attached to the bottom surface of the bridge body 19 after the connecting plate 11 and the sleeve 10 are fixed, and at the same time a pair of base plates 1 are symmetrically arranged and respectively fastened to both sides of the pier 18 as a suitable support position.

[0058] In this technical solution, a pair of base plates 1 are interlocked and fixed to the pier 18. Threaded sleeves 16 are provided on both sides of the base plates 1 to improve the stability of the interlocking and fixing of the pair of base plates 1, ensuring the supporting function. After the threaded tensioner 15 is tightened, the locking nut 17 is rotated in the opposite direction, causing the locking nut 17 to abut against the adjacent threaded sleeve 16. Then, a groove is opened on the side of the base plate 1 near the pier 18, and the first pressure plate 3, the first spring 4, and the first contact pad 5 are placed in the groove. The first spring 4 supports the first pressure plate 3, causing the first contact pad 5 to abut against the pier 18. The jack 13 is then activated to support the top plate 2. After rotating relative to the base plate 1 and abutting against the bottom surface of the bridge body 19, the second pressure plate 6 is rotatably fixed to the adjusting screw 20 by rotating the adjusting screw 20 through the bearing. Under the action of the thread, the second pressure plate 6 moves along the side wall of the adjacent pier 18 until the second contact pad 8 abuts against the side wall of the pier 18, thereby realizing the prestress applied to the top plate 2. Under the support and fixing action of the jack 13 on the top plate 2, the fixing action between the top plate 2 and the bridge is improved. At the same time, while the top plate 2 is supported and fixed, the third contact pad 9 abuts against the bottom surface of the bridge body 19, and the second contact pad 8 abuts against the adjacent pier 18, completing the angle support action matching the bridge structure.
