Description

Technical Field

[0001] This utility model relates to the field of rigid frame bridge construction technology, and in particular to a bracket structure for a long-span continuous rigid frame bridge. Background Technology

[0002] During the construction of rigid frame bridges, brackets are needed to assist in the construction. However, most existing brackets are fixed to the bracket body on the pre-embedded connectors on the bridge pier by welding or other methods. This method of bracket installation depends on the pre-embedded connectors on the bridge pier. When there are no pre-embedded connectors on the bridge pier, the bracket is difficult to install on the bridge pier, which has a great impact on the construction.

[0003] To address the aforementioned issues, a search revealed, for example, a high-pier, long-span continuous rigid frame bridge support structure provided by patent publication number CN215164751U. This structure includes an installation plate, a fixing block fixedly connected to the center of one side of the installation plate, a movable rod movably connected to one side of the fixing block via a pin, a support plate at one end of the movable rod, and a connecting block fixedly connected to the center of the lower surface of the support plate. One side of the connecting block is movably connected to one end of the movable rod via a pin. By configuring the installation plate, support plate, and bonding plate, with the movable rod and support rod movably connected to each other via pins, and the installation plate and bonding plate fixed to the pier by positioning pins, the support plate assists in construction. When the support plate is under stress, the installation plate and bonding plate convert the vertical force on the support plate into an inclined force towards the pier, thereby ensuring the stability of the support plate.

[0004] Based on the above search and analysis of existing technologies, it has been found that the mounting plates and bonding plates in existing rigid frame bridge bracket structures similar to those disclosed above lack effective positioning during installation, making them prone to displacement and causing the support plates to tilt. Therefore, a long-span continuous rigid frame bridge bracket structure is proposed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this application is to provide a long-span continuous rigid frame bridge bracket structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a large-span continuous rigid frame bridge bracket structure, including two mounting plates, with a tie rod horizontally connected between the two mounting plates. Both ends of the tie rod are provided with a first threaded section, which penetrates through the mounting plate. A first fixing nut is threaded onto the outer side of the first threaded section, and the first fixing nut abuts against the mutually distant end faces of the two mounting plates. A positioning pin is threaded through the horizontal thread on the mounting plate. A support plate is fixed horizontally at the upper end of the mounting plate. A diagonal brace is fixed between the lower end of the support plate and the mounting plate on the side away from the mounting plate.

[0007] As a further supplement to this solution, the mounting plate is provided with a first waist hole for the first threaded section to pass through.

[0008] As a further supplement to this solution, auxiliary installation components are provided on the upper side of the mounting plate. These auxiliary installation components include a positioning support plate, a hoisting plate, and a connecting column. The hoisting plate is located above the positioning support plate, and an adjustment structure is provided between the hoisting plate and the positioning support plate. Both support plates are connected to the hoisting plate through connecting columns.

[0009] As a further supplement to this solution, the adjustment structure includes an adjustment screw and a guide rod. The adjustment screw is vertically threaded through the hoisting plate and rotatably connected to the positioning support plate. The guide rod is vertically slidably through the hoisting plate and fixed to the positioning support plate.

[0010] As a further supplement to this solution, the lower end of the connecting column is provided with a second threaded section that penetrates the support plate. The upper side of the second threaded section is integrally fixed with a limiting block that abuts against the top surface of the support plate, and the outer side of the second threaded section is threaded with a second fixing nut that abuts against the bottom surface of the support plate.

[0011] As a further supplement to this solution, the support plate is provided with a second waist hole for the second threaded section to pass through.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the two mounting plates can be initially positioned and fixed on both sides of the pier quickly and stably through the cooperation of the tie rod and the first fixing nut, thereby facilitating the accurate installation of the positioning pin. The setting of the first waist hole allows the tie rod to have a certain position adjustment space during installation to adapt to piers of different sizes.

[0013] 2. In this utility model, through the coordinated arrangement of positioning support plate, lifting plate, connecting column, adjusting screw and guide rod, when the adjusting screw is rotated, the lifting plate will move up and down along the guide rod, thereby realizing the precise adjustment of the height of the lifting plate. The lifting plate is connected to the support plate through the connecting column, which in turn enables the precise adjustment of the height of the support plate, making it more convenient for the accurate installation of the bracket structure.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] refer to Figure 1-4 The large-span continuous rigid frame bridge bracket structure shown includes two mounting plates 1, with a tie rod 2 horizontally connected between the two mounting plates 1. Both ends of the tie rod 2 are provided with a first threaded section 21, which penetrates the mounting plate 1. A first fixing nut 22 is threaded onto the outer side of the first threaded section 21, and the first fixing nut 22 abuts against the opposite ends of the two mounting plates 1. A first waist hole 101 is provided on the mounting plate 1 for the first threaded section 21 to pass through.

[0019] With the cooperation of the tie rod 2 and the first fixing nut 22, the two mounting plates 1 can be initially positioned and fixed on both sides of the pier quickly and stably, which facilitates the accurate installation of the positioning pin 3. The setting of the first waist hole 101 allows the tie rod 2 to have a certain position adjustment space during installation to adapt to piers of different sizes.

[0020] A positioning pin 3 is threaded through the horizontal thread on the mounting plate 1. A support plate 4 is horizontally fixed to the upper end of the mounting plate 1. A diagonal brace 5 is fixed between the lower end of the support plate 4 away from the mounting plate 1 and the mounting plate 1. The positioning pin 3 passes through the mounting plate 1 and is inserted into the pier, further enhancing the connection stability between the mounting plate 1 and the pier and preventing the mounting plate 1 from sliding under force. The support plate 4 provides a stable support platform for subsequent hoisting and other operations. The diagonal brace 5 further improves the rigidity and stability of the entire bracket structure and can withstand large loads. Example

[0021] Based on Embodiment 1, an auxiliary installation component is provided on the upper side of the mounting plate 1. Specifically, the auxiliary installation component includes a positioning support plate 6, a lifting plate 7, and a connecting column 8. The lifting plate 7 is located on the upper side of the positioning support plate 6, and an adjustment structure is provided between the lifting plate 7 and the positioning support plate 6. Both support plates 4 are connected to the lifting plate 7 through the connecting column 8.

[0022] The adjustment structure includes an adjusting screw 11 and a guide rod 12. The adjusting screw 11 is vertically threaded through the lifting plate 7 and rotatably connected to the positioning support plate 6. The guide rod 12 is vertically slidably through the lifting plate 7 and fixed to the positioning support plate 6. When the adjusting screw 11 is rotated, the lifting plate 7 will move up and down along the guide rod 12, thereby achieving precise adjustment of the height of the lifting plate 7. The lifting plate 7 is connected to the support plate 4 through the connecting column 8, thereby enabling precise adjustment of the height of the support plate 4.

[0023] The lower end of the connecting column 8 is provided with a second threaded section 81 that penetrates the support plate 4. The upper side of the second threaded section 81 is integrally fixed with a limiting block 9 that abuts against the top surface of the support plate 4. The outer side of the second threaded section 81 is threaded with a second fixing nut 10 that abuts against the bottom surface of the support plate 4. The support plate 4 is provided with a second waist hole 401 for the second threaded section 81 to pass through.

[0024] Based on the above structural arrangement, before fixing the two mounting plates 1 to both sides of the pier using the tie rod 2 and the first fixing nut 22, the support plate 4 and the lifting plate 7 can be connected using the second threaded section 81 and the second fixing nut 10. Then, the frame consisting of the mounting plate 1 and the tie rod 2 is placed on the outside of the pier, so that the positioning support plate 6 is placed on the top of the pier. Then, the adjusting screw 11 is rotated so that the lifting plate 7 moves up and down along the guide rod 12. The lifting plate 7 moves up and down synchronously with the support plate 4 through the connecting column 8, so that the height of the support plate 4 can be precisely adjusted. After the height of the support plate 4 is adjusted, the two mounting plates 1 can be fixed to both sides of the pier using the tie rod 2 and the first fixing nut 22. Then, the positioning pin 3 is used to penetrate the mounting plate 1 and insert into the pier to enhance the connection stability between the mounting plate 1 and the pier and prevent the mounting plate 1 from sliding down under force. Finally, the second fixing nut 10 is loosened and the auxiliary installation components can be removed.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
