[0003] It is found that the publication number: CN212452288U discloses a construction support for a concrete bridge deck of a steel-concrete composite beam. This technology discloses "support columns, support crossbeams, suspension rods, bottom forms and construction channels. The number of support columns and suspension rods is multiple. The support crossbeam is horizontally arranged, and multiple support columns are vertically connected at intervals below the support crossbeam. The bottoms of the multiple support columns are horizontally connected with the bottom form. The support crossbeam and the bottom form are connected by multiple suspension rods, and the construction channel is connected below the bottom form, solving the problem that the main load-bearing structure support of the bridge deck in the existing bridge deck construction by the bracket method is below the bridge deck, and the whole is a compression structure with a large weight. The support is usually welded or bolted to the steel plate beam, damaging the coating of the steel plate beam. The support of the utility model is above the bridge deck, mainly a tensile structure, with a small overall weight. The welding position of the support and the steel plate beam is on the non-coated part of the top surface of the steel plate beam, effectively protecting the coating";

[0004] Although this design is a tensile structure with a small overall weight, and the welding position of the support and the steel plate beam is on the non-coated part of the top surface of the steel plate beam, effectively protecting the coating, this device can only maintain and construct the bridge body at a fixed position during the working process. Then, during the continuous bridge construction process, it is necessary to frequently adjust or move the position of this device. Then, a large amount of time will be consumed during this process, thereby affecting the construction progress and reducing the construction efficiency.

[0005] To solve the above problems, a construction support for a concrete bridge deck of a steel-concrete composite beam is proposed in this application. Content of the Utility Model

And through the transfer module, the device can also smoothly cross the bridge pier without disassembling and assembling the main body, effectively improving the maintenance and construction efficiency, and thus achieving the purpose of shortening the construction time.

[0007] To achieve the above object, the present utility model provides the following technical solution: A construction support for a concrete bridge deck of a steel-concrete composite beam, including a bridge body, and further including a guide rail, a roller, a side plate, a protection passage, an access ladder, a construction frame, and a transfer module provided on one side of the bridge body. The guide rail is fixedly installed on one side of the bridge body, and the guide rail is also engaged with the roller, and the roller is also rotatably connected to one side surface of the side plate.

When the side plate 4 and the construction frame 7 move to the position of the bridge pier, the transfer module 8 on the side close to the bridge pier can be removed, and the side plate 4 and the construction frame 7 can be further moved. Subsequently, the transfer module 8 on the side close to the bridge pier can be removed, and the transfer module 8 can be filled on the side of the construction frame 7 that has passed over the bridge pier by means of bolt connection. When the transfer module 8 on the outermost side is successfully removed, the side plate 4 and the construction frame 7 can stably cross the bridge pier and realize continuous maintenance work.

At this time, the side plate 4 and the roller 3 can be controlled to move along the guide rail 2, and the roller 3 will rotate with the side plate 4 and roll along the guide rail 2. When the side plate 4 and the construction scaffold 7 move to the position of the pier, the transfer module 8 on the side close to the pier can be removed, and the side plate 4 and the construction scaffold 7 can be further moved. Subsequently, the transfer module 8 on the side close to the pier can continue to be removed, and the transfer module 8 can be filled on the side of the construction scaffold 7 that has crossed the pier by means of bolt connection. When the transfer module 8 at the rearmost end is successfully removed, the side plate 4 and the construction scaffold 7 can stably cross the pier and achieve continuous maintenance work.
