Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] Reference Figures 1 to 9 As shown, this utility model embodiment provides a novel scaffold for replacing bridge plate rubber bearings, including several equally spaced mounting frames 1. Each mounting frame 1 has two mounting connecting seats 11 at its bottom. A square steel 12 is provided between the mounting connecting seats 11 of two adjacent mounting frames 1. The square steel 12 is connected to the mounting connecting seats 11 by two connecting bolts 13. A horizontally arranged mounting plate 2 is provided between two adjacent mounting frames 1. Two connecting pieces 3 are provided between the two mounting plates 2. Several fixing pieces 4 are provided between the mounting plates 2 and the mounting frames 1 for fixing. Each square steel 12 is provided with a connecting ear 5 for installation. Each mounting frame 1 is provided with a mounting ear 6 for installation.

[0017] This utility model adopts a modular design and standardized component production, enabling rapid assembly and disassembly, significantly improving construction efficiency and shortening the construction period. Through double-bolt connections and double-fixing components 4, it ensures reliable connections and overall stability, with strong load-bearing capacity. The connecting ears 5 and mounting ears 6 are adaptable to various bridge structures, allowing for flexible fixing and functional expansion, adapting to complex environments such as high piers and river channels. The protective net 7 design enhances operational safety. All components are lightweight and reusable, reducing material costs and transportation difficulties. It eliminates the need for traffic closures or large equipment, minimizing disruption to traffic flow, and combines economic efficiency with practicality, providing an efficient, safe, and convenient construction platform for replacing bridge plate rubber bearings.

[0018] Specifically, the connector 3 is a connecting plate 31, and the mounting plate 2 is provided with a mounting groove 21 for mounting the connecting plate 31. The two ends of the connecting plate 31 are respectively connected to the two mounting grooves 21 of the two mounting plates 2, and the two ends of the connecting plate 31 are provided with two mounting screws 32.

[0019] The two ends of the connecting plate 31 are inserted into the mounting slots 21 of the two mounting plates 2 and locked by the mounting screws 32, connecting the scattered mounting plates 2 into a whole, reducing platform shaking, improving the flatness of the working surface, and the mounting plates 2 are set to provide a platform for workers to operate.

[0020] Specifically, each of the fixing components 4 includes a fixing plate 41, a rotating shaft 42, a plug-in rod 43, and a spring 44. The bottom of the mounting plate 2 is provided with a fixing groove 47. The rotating shaft 42 is located at the top of the fixing plate 41. The fixing plate 41 is rotatably connected to the fixing groove 47 through the rotating shaft 42. The side wall of the fixing plate 41 is provided with four mounting screw holes 46. The spring 44 is connected to the plug-in rod 43. The side wall of the fixing groove 47 is provided with a moving hole. The spring 44 is connected in the moving hole and the plug-in rod 43 slides between the moving hole and the moving hole. The side wall of the fixing plate 41 is provided with a plug-in hole 45 for the plug-in rod 43 to be inserted. The end of the plug-in rod 43 is rounded.

[0021] When fixing the mounting plate 2, the fixing plate 41 is rotated out of the fixing groove 47 through the rotating shaft 42, so that the fixing plate 41 is in a vertical position at the side wall of the square steel 12. Then, the bolts can be inserted into the insertion holes 45 on the fixing plate 41, thereby fixing the position of the fixing plate 41 to the square steel 12, thus achieving the fixation between the mounting plate 2 and the square steel 12. When the mounting plate 2 is disassembled, the fixing plate 41 can be rotated into the fixing groove 47 via the pivot 42. During rotation, the fixing plate 41 will abut against the insertion rod 43, thereby compressing the spring 44 and causing the insertion rod 43 to move within the moving hole. When the fixing plate 41 is placed horizontally in the fixing groove 47, the spring 44 returns to its original position, causing the insertion hole 45 to move within the moving hole, inserting the insertion rod 43 into the insertion hole 45 on the fixing plate 41. This fixes the fixing plate 41 in the fixing groove 47, facilitating the stacking of several mounting plates 2 and subsequent transportation.

[0022] Specifically, the connecting ear 5 includes a front plate 51, a connecting cylinder 52, and a rear plate 53. The front plate 51 and the rear plate 53 are located at both ends of the connecting cylinder 52. The front plate 51 is bolted to the side wall of the square steel 12, and the rear plate 53 is provided with a connecting hole 54.

[0023] The front plate 51 is connected to the square steel 12 by bolts, and the connecting hole 54 of the rear plate 53 can be used with the pier embedded parts, steel clamps or steel cables to fix the scaffolding to the pier or cap beam, adapting to environments without ground support such as river channels and high altitudes. Specifically, the mounting ear 6 is provided with four mounting holes 61. The four mounting holes 61 on the mounting ear 6 are used for connection with the bridge pier, which can be connected by expansion bolts; the connecting cylinder 52 connects the front plate 51 and the rear plate 53 to form a rigid support, which transmits the lateral force of the scaffolding to the bridge pier structure and avoids deformation of the square steel 12 under single-point stress.

[0024] Specifically, several installation frames 1 are equipped with detachable protective nets 7 on their outer side walls. The detachable protective nets 7 surround the outside of the work platform to prevent construction tools or personnel from falling, making them especially suitable for high-altitude work scenarios. The protective nets 7 can be spliced ​​according to the number of installation frames 1, and disassembly does not affect the storage and transportation of the main scaffold structure, resulting in a high reuse rate.

[0025] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
