Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a short cantilever bracket for a cast-in-place section of a bridge side span and a construction method thereof. Background Art

[0002] With the continuous development of bridge construction technology, large-span continuous beam reinforced concrete bridges have been widely used. The construction of the cast-in-place section of the side span affects the construction quality and project progress of the entire bridge. The existing construction of the cast-in-place section of the side span is mainly carried out through hanging basket bracket construction.

[0003] The construction of the hanging basket bracket requires fixing the walkway beam on the already cast bridge, and then installing the hanging basket bracket on the walkway beam, and installing a lifting rope for connecting the hanging basket on the side of the hanging basket bracket beyond the bridge, and connecting the hanging basket to the end of the lifting rope facing away from the hanging basket bracket. Then, install the bridge mold on the hanging basket, and then install the steel bars and concrete in the bridge mold. After the concrete solidifies to a fixed strength, remove the bridge mold, and extend the walkway beam on the newly cast bridge. Then, move the hanging basket bracket forward along the walkway beam to carry out the construction of the next side span cast-in-place section.

[0004] When installing the existing hanging basket bracket, it is necessary to fix the hanging basket bracket to the walkway beam through anchor bolts, and then remove the anchor bolts after the pouring is completed. This not only increases the workload of the workers, but also slows down the construction speed of the project. Summary of the invention

[0005] In order to reduce the workload of workers during the construction of the cast-in-place section of the bridge side span and speed up the construction of the project, the present application provides a short cantilever bracket for the cast-in-place section of the bridge side span.

[0006] The above technical objectives of this application are achieved through the following technical solutions: A short cantilever bracket for a cast-in-place section of a side span of a bridge comprises a walkway beam, a hanging basket bracket and a hanging basket, wherein the walkway beam is fixedly connected to a bridge body, a sliding structure enabling the hanging basket bracket to slide on the walkway beam is provided between the hanging basket bracket and the walkway beam, and a fixing structure enabling the hanging basket bracket to be fixed or loosened from the walkway beam is provided between the hanging basket bracket and the walkway beam, a hanging rope is provided on a side of the hanging basket bracket extending out of the bridge, and the end of the hanging rope facing away from the hanging basket bracket is connected to the hanging basket.

[0007] By adopting the above scheme, when pouring the beam body, the fixed structure fixes the walkway beam and the hanging basket bracket, and then the beam body is poured. After the beam body solidifies, the walkway beam is installed on the newly poured beam body, and then the fixed structure loosens the hanging basket bracket and the walkway beam, and the sliding structure allows the hanging basket bracket to slide along the walkway beam to prepare for pouring the next section of the beam body, so that workers do not need to install and then remove the hanging basket bracket, thereby reducing the workload of workers during the construction of the cast-in-place section of the bridge side span and speeding up the construction of the project.

[0008] Optionally, a slide groove is provided on the upper surface of the walkway beam, and the sliding structure includes a connecting rod, which is fixedly connected to the hanging basket bracket, and the end of the connecting rod facing away from the hanging basket bracket is located in the slide groove, and the end of the connecting rod located in the slide groove is rotatably connected to a wheel rod, and both ends of the wheel rod are connected to rollers, and the rollers are located in the slide groove.

[0009] By adopting the above solution, by setting the roller to slide in the slide groove, the sliding of the walkway beam and the hanging basket bracket is smoother, and the hanging basket bracket is prevented from separating from the walkway beam, making the hanging basket bracket safer during the movement process.

[0010] Optionally, a rack is fixedly connected to the upper surface of the walkway beam, a first motor is fixedly connected to the lower surface of the hanging basket bracket, and an output shaft of the first motor is fixedly connected to a gear, which meshes with the rack.

[0011] By adopting the above solution, the rotation of the first motor drives the gear to rotate, and the gear rolls along the rack, thereby driving the hanging basket bracket to automatically move along the walkway beam, thereby further reducing the workload of the operator.

[0013] By adopting the above scheme, when it is necessary to fix the hanging basket bracket and the walkway beam, the piston rod of the telescopic cylinder is extended, thereby driving the vertical slider to slide in the vertical through hole, so that the end of the vertical slider is inserted into the first slot, thereby fixing the hanging basket bracket and the walkway beam; when it is necessary to release the hanging basket bracket and the walkway beam, the piston rod of the telescopic cylinder is retracted, thereby driving the vertical slide bar to slide out of the first slot, thereby releasing the fixing of the hanging basket bracket and the walkway beam, thereby reducing the workload of workers in the construction of the cast-in-place section of the side span of the bridge.

[0014] Optionally, a horizontal through hole is opened inside the slider, the horizontal through hole is connected with the vertical through hole, and a horizontal slide bar is arranged in the horizontal through hole, and there are two horizontal slide bars, which are respectively arranged on opposite sides of the vertical slide bar, and the horizontal slide bar is inclined near one end of the vertical slide bar, with the inclined surface facing upward, and inclined blocks are arranged on both sides of the vertical slide bar near the horizontal slide bar, with the inclined surfaces of the inclined blocks facing downward, and a second slot is opened in the slide slot opposite to the horizontal slide hole, and when the vertical slider moves downward, the inclined block contacts the horizontal slide bar, and the inclined block presses the horizontal slide bar into the second slot.

[0015] By adopting the above scheme, when the piston rod of the telescopic cylinder is extended, it drives the vertical slide bar to move downward, thereby driving the inclined block to move downward. The inclined block contacts the inclined surface of the horizontal slide bar, thereby pressing the horizontal slide bar into the second slot, thereby further increasing the fixing strength of the walkway beam and the hanging basket bracket.
