[0002] Box girders are a type of beam used in bridge engineering. They come in single-box and multi-box configurations, and are hollow inside with flanges on both sides of the upper part, resembling a box, hence the name. Reinforced concrete box girders are divided into precast box girders and cast-in-place box girders. Box girders precast in an independent site can be erected after the substructure is completed using a bridge erection machine, which can accelerate the project progress and save time. Currently, the binding of box girder reinforcement is limited by the reinforcement processing site, the size of the box girder reinforcement cage, and the location of the binding points. Often, the box girder reinforcement cage is placed on a reinforcement positioning mold (a device for making the box girder reinforcement cage), and then manually bound with a handheld reinforcement binding machine. This binding method has the following problems: manual binding of the box girder reinforcement cage for a long time is prone to fatigue, leading to decreased efficiency, and fatigue also increases the likelihood of errors, resulting in rework.

[0012] A method for using a box girder reinforcement cage binding device includes the following steps: S1, according to the layout design of the reinforcement processing site, the reinforcement positioning form and the ground track are installed in the reinforcement processing site in a group manner of reinforcement positioning form-ground track-reinforcement positioning form; S2, install the first moving device on the ground track, and then install the first telescopic device, the binding track, and the moving binding device in sequence; S3, after the box girder steel reinforcement skeleton on the steel reinforcement positioning form is tied and positioned, the first moving device is controlled by the control equipment to move along the ground track, so that the tying track moves to one end of the box girder steel reinforcement skeleton. S4. By using two distance sensors installed on the inside of the binding track, the construction workers control the first telescopic device to move the binding track left and right, adjusting the left and right spacing area of ​​the binding track and the rebar positioning formwork to be consistent. S5, the high-definition camera transmits the image information of the local binding area of ​​the box girder steel reinforcement skeleton to the control equipment. The construction personnel use the image information of the local binding area displayed on the display screen of the control equipment to control the moving binding device to adjust the binding angle and bind the box girder steel reinforcement skeleton. At the same time, the moving binding device moves at intervals along the binding track. S6, the construction workers control the first moving device to continue moving along the ground track through the control equipment, and repeat step S5 until the binding of the box girder steel reinforcement cage on this side is completed. S7, the construction workers control the first moving device to continue moving along the ground track through the control equipment, so that the binding track moves to the top of the box girder steel reinforcement skeleton on the other side of the ground track, and repeat steps S4-S6 to complete the binding of the box girder steel reinforcement skeleton on the other side. S8. Repeat step S7 until all the box girder steel reinforcement cages are tied.

[0013] Advantages of this invention: Because this device uses a circular ground track, when laying out the rebar positioning formwork and ground track on the rebar processing site, it can be installed in a set manner of rebar positioning formwork-ground track-rebar positioning formwork. This not only reduces the amount of binding equipment used, but also, during use, since one set of binding equipment can alternately bind the box girder rebar skeleton on the two rebar positioning formworks on its left and right sides, it can achieve maximum utilization efficiency of the rebar positioning formwork and binding equipment, as well as continuous processing of the box girder rebar skeleton, thus accelerating the processing efficiency of the box girder rebar skeleton.

[0014] The U-shaped binding rail is used as the moving rail for the binding equipment. Since one end of the binding rail is suspended, it avoids laying ground rails on the outside of the rebar positioning formwork. This not only saves materials, but also ensures that the rebar positioning formwork is not affected by the ground rails when it moves. At the same time, it also leaves more space for stacking box girder rebar skeletons on the rebar processing site.

[0015] During the binding process, construction workers can control the first telescopic device to move the binding track left and right through the control equipment, adjusting the binding track to be consistent with the left and right spacing area of ​​the rebar positioning formwork. This ensures that when the subsequent moving binding device binds on both sides, the distance between it and the rebar positioning formwork is consistent, reducing the number of distance adjustment calculations. At the same time, for rebar positioning formwork of different widths, the position of the binding track can be adjusted to ensure that the rebar positioning formwork of different widths is always in the middle of the binding track.

[0016] This device can replace manual labor in tying the steel reinforcement cage of box girders, greatly reducing the labor intensity of workers in the process of tying the steel reinforcement cage of box girders, and also significantly reducing the error rate of manual tying, thus improving work efficiency.
