[0031] Example 1

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A rigid frame continuous beam bridge pier top bracket comprises a bridge pier column 1, a bracket body 2 is arranged on the top of the bridge pier column 1, a slot 3 is opened on the top of the bridge pier column 1, fixing holes 4 are opened on both sides of the bridge pier column 1, and a circular groove 5 is arranged at the bottom of the fixing hole 4, a connecting component 6 is arranged between the bridge pier column 1 and the bracket body 2, and a supporting component 7 is arranged on the top of the connecting component 6, and the connecting component 6 comprises a plug-in 61, a cross bar 62 is embedded at the bottom of the plug-in 61, square grooves 63 are opened at both ends of the cross bar 62, an L-shaped plate 64 is arranged on the top of the square groove 63, a threaded groove 65 is opened at the bottom of the L-shaped plate 64, a circular ring 66 is arranged on one side of the L-shaped plate 64, and a threaded rod 69 is arranged on the other side of the L-shaped plate 64. Four inclined plates 67 are evenly connected to one side of the circular ring 66, and a plurality of protrusions 68 are evenly connected to the outer wall of the inclined plate 67. The circular ring 66 is fixedly embedded in one side of the plug-in 61, and the plug-in 61 is engaged with the slot 3. The circular groove 5 is provided on one side of the pier column 1, the L-shaped plate 64 is movably embedded in the square groove 63, the middle of the crossbar 62 is fitted with the inner wall of the fixing hole 4, the side wall of the L-shaped plate 64 is fitted with the side wall of the pier column 1, and the threaded rod 69 is threadedly connected with the inner wall of the circular groove 5 and the threaded groove 65 in sequence. The support assembly 7 includes a square frame 71, the bottom end of the square frame 71 is fitted with the top end of the L-shaped plate 64, and a plurality of plug holes 72 are evenly provided on both sides of the top end of the square frame 71. The top of the square frame 71 is provided with an inclined rod 73, both ends of the inclined rod 73 are connected with connecting pieces 74, and the bottom end of the inclined rod 73 is provided with an insert block 75, and both sides of the insert block 75 are connected with baffles 76. The connecting piece 74 at the top is connected to the bottom end of the bracket body 2, and the connecting piece 74 at the bottom is connected to the top end of the insert block 75. The insert block 75 is movably embedded in the insert hole 72 , the bottom end of the baffle 76 is in contact with the top end of the square frame 71 , and the square frame 71 is sleeved in the middle of the pier column 1 .

[0033] First, insert the plug-in 61 precisely into the corresponding slot 3 to ensure that the plug-in 61 is completely embedded in the slot 3. At this time, the bottom end of the bracket body 2 is tightly fitted to the top end of the pier column 1. On both sides of the plug-in 61, we have opened corresponding holes, which need to correspond to the fixing holes 4.

[0034] Next, the crossbar 62 is passed through the fixing holes 4 and the two plug-ins 61 of different sizes in sequence to ensure a more stable connection between the plug-ins 61, the bracket body 2 and the pier column 1. Subsequently, the L-shaped plate 64 is inserted from top to bottom into the square groove 63 so that the structure at the top of the plate is engaged with the top of the square groove 63, thereby fixing the crossbar 62 to prevent it from shaking.

[0035] In order to further enhance the stability of the connection, the threaded rod 69 is screwed through the inside of the threaded groove 65, and one end of the threaded rod 69 is screwed through the inside of the circular groove 5, and is threadedly connected with the circular ring 66 embedded in one side of the plug 61. In this way, one end of the threaded rod 69 pushes the inclined plate 67 outward, and the protrusion 68 also opens outward and engages with the inside of the plug 61. This method makes the connection between the L-shaped plate 64 and the bridge pier column 1 tighter, effectively avoiding the shaking of the bracket body 2 that may be caused by vibration during the construction process, thereby ensuring the safety and precision of the construction.

[0036] Before installing the connection assembly 6, we also need to sleeve the square frame 71 on the outside of the pier column 1. After the connection assembly 6 is installed, the square frame 71 should be located on the top of the crossbar 62, and its bottom end is in contact with the top end of the L-shaped plate 64.

[0037] In addition, the bottom end of the bracket body 2 is rotatably connected to the inclined rod 73 through the connecting piece 74, and the bottom of the inclined rod 73 is rotatably connected to the plug block 75 through the connecting piece 74. Therefore, after the connection assembly 6 is installed, we can rotate the inclined rod 73 to make the bottom connecting piece 74 drive the plug block 75 to move to the top of the square frame 71, and insert the plug block 75 into the corresponding insertion hole 72. In this way, a stable triangular bracket shape is formed between the inclined rod 73, the bridge pier column 1 and the bracket body 2, providing a stronger support for the bracket body 2.

[0038] Preferably, modular bearing components 8 are provided on both sides of the bracket body 2, and a quick locking component 9 is provided at the bottom of the modular bearing component 8; the modular bearing component 8 includes a fixing plate 81, a cross plate 82 is provided on one side of the fixing plate 81, and clamping grooves 83 are provided at the four corners of the cross plate 82, a threaded through groove 84 is provided at the bottom end of the inner wall of the clamping groove 83, and a placement groove 85 is provided in the middle of the fixing plate 81. The fixing plate 81 is connected to the bracket body 2, and the fixing plate 81 is engaged with the clamping groove 83. The quick locking assembly 9 includes a fixing ring 91, the outer wall of the fixing ring 91 is connected to the inner wall of the placement groove 85, the inner wall of the fixing ring 91 is connected to an oblique ring 92, an outer cylinder 93 is arranged at the bottom of the fixing ring 91, a retaining ring 94 is fixedly connected to the middle of the outer cylinder 93, the outer cylinder 93 is threadedly connected to the threaded through groove 84, the top of the retaining ring 94 is fitted with the bottom end of the cross plate 82, both sides of the top of the outer cylinder 93 are provided with fixing grooves 95, and a moving rod 96 is arranged inside the outer cylinder 93. A groove 97 is arranged at the top of the moving rod 96, and two round balls 98 are movably connected inside the groove 97. A spring 99 is connected to the bottom of the moving rod 96, and one end of the spring 99 is connected to the inner wall of the outer cylinder 93. The fixing plate 81 is fixedly connected to one side of the bracket body 2 to ensure the stability of the structure. The fixing plate 81 is designed to be a regular rectangular shape, or one end of the bracket body 2 can be directly processed into a regular rectangle, and a placement groove 85 is opened on the surface of this rectangle. In the placement groove 85, we fixedly installed the fixing ring 91. The cross plate 82 is cleverly engaged on one side of the fixing plate 81. Through the fixing plate 81 with the placement groove 85, we can easily connect multiple cross plates 82. When connecting, it is necessary to ensure that the placement groove 85 and the threaded through groove 84 correspond to each other, and the fixing ring 91 is firmly installed inside the placement groove 85.

[0039] In order to facilitate transportation and storage, we adopted a standardized cross-plate 82 design. When in use, just connect multiple cross-plates 82. This design not only simplifies the transportation and storage process, but also effectively reduces material waste and improves resource utilization efficiency through large-scale production.

[0040] When connecting multiple cross plates 82, we use a quick locking assembly 9. First, a fixing ring 91 is preset inside the placement groove 85. Then, the clamping groove 83 is engaged with one side of the fixing plate 81, and the outer cylinder 93 is screwed so that its thread penetrates the threaded through groove 84 and penetrates into the inside of the fixing plate 81. In this process, the top of the retaining ring 94 fits tightly with the bottom of the cross plate 82, and the top of the outer cylinder 93 penetrates into the inside of the fixing ring 91.

[0041] In order to ensure that the outer cylinder 93 can smoothly enter the fixed ring 91, the staff needs to continuously push the moving rod 96 so that the ball 98 at the top of the moving rod 96 is located above the fixed groove 95. When the outer cylinder 93 is completely embedded in the fixed ring 91 and the fixed groove 95 is located at the top of the oblique ring 92, pull the moving rod 96 downward. At this time, the spring 99 is no longer compressed and begins to generate a downward thrust. Under the combined effect of gravity and the thrust of the spring 99, the moving rod 96 moves toward the bottom of the outer cylinder 93, and the groove 97 is pulled downward accordingly, so that the ball 98 is engaged between the groove 97 and the oblique ring 92, and the outside of the ball 98 is embedded in the inside of the fixed groove 95. This design ensures that the connection between the cross plate 82 and the fixed plate 81 is more stable and reliable.
