Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary device for binding the reinforcing bars of large-section reinforced concrete beams. Background Technology

[0002] Reinforcing bars refer to steel materials used in reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. They include plain round bars, ribbed bars, and twisted bars. During the construction process, reinforcing bars are tied. Auxiliary devices are used when tying reinforcing bars in large-section reinforced concrete beams.

[0003] However, existing tying auxiliary devices have limitations when tying the reinforcing bars of large-section beams during construction. Workers' arms cannot tie the bottom and web reinforcement bars of the beams. They can only use the skip-formwork method during formwork erection, leaving one side of the beam formwork unsupported until the beam reinforcement is tied. This results in steelworkers and carpenters working at different times, steelworkers working at heights, low construction efficiency, and quality problems in the reinforcement tying, which are difficult to rectify. Therefore, a new reinforcement tying auxiliary device for large-section reinforced concrete beams has been developed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for tying reinforcing bars in large-section reinforced concrete beams. This device is simple in structure, easy to use, and applicable to tying reinforcing bars in beams of different cross-sections. It solves the problem that during construction, when tying reinforcing bars in large-section beams, workers' arms cannot reach to tie the bottom and web reinforcement bars. This necessitates using a skip-formwork method during formwork erection, leaving one side of the beam formwork unsupported until the beam reinforcement is tied, leading to overlapping work between steelworkers and carpenters, steelworkers working at heights, low construction efficiency, and quality problems in the reinforcement tying process, making rectification difficult.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for tying reinforcing bars of a large-section reinforced concrete beam, comprising a box body, a motor movably connected to the right side of the box body via a first bearing, a threaded rod fixedly connected to the output end of the motor, threaded sleeves fitted on both sides of the surface of the threaded rod, a movable rod fixedly connected to the bottom of the threaded sleeves, the bottom of the movable rod penetrating to the bottom of the box body and fixedly connected to a mounting box, a mounting plate provided in the inner cavity of the mounting box, an upper lifting rod provided between two mounting boxes, a movable rod provided on the side of the inner cavity of the mounting box away from the upper lifting rod, a movable plate fitted on the surface of the movable rod, a spring fixedly connected between the movable plate and the inner cavity of the mounting box, and the side of the mounting plate away from the upper lifting rod... A slot is provided on one side. The side of the movable rod away from the spring passes through the inner cavity of the slot and is fixedly connected to a locking block. The side of the movable rod away from the movable plate passes through the side of the mounting box away from the upper hanging rod and is fixedly connected to a limiting plate. The bottom of the mounting plate passes through the bottom of the mounting box and is fixedly connected to a column. A crossbeam is fixedly connected to the top of the column. A sleeve is fixedly connected to the top of the crossbeam. A manual hoist is provided at the bottom of the upper hanging rod. A lifting chain is provided on the left side of the bottom of the manual hoist. A zipper is provided on the right side of the bottom of the manual hoist. A lower hanging rod is provided at the bottom of the manual hoist. Lifting rings are fitted on the surfaces of both the upper and lower hanging rods. The side of the upper hanging rod away from the manual hoist passes through the sleeve away from the manual hoist.

[0006] Preferably, the surface of the motor is covered with a protective shell, the protective shell is fixedly connected to the housing, and the front of the protective shell is fixedly connected with heat dissipation louvers.

[0007] Preferably, a first slider is fixedly connected to the top of the threaded sleeve, and a first groove adapted to the first slider is provided on both sides of the top of the inner cavity of the box.

[0009] Preferably, the top and bottom of the movable plate are fixedly connected to a second slider, and the top and bottom of the mounting box cavity are provided with a second sliding groove adapted to the second slider.

[0010] Preferably, the spring is sleeved on the surface of the movable rod, and the bottom of the mounting box has a through groove adapted to the mounting plate.

[0011] Preferably, a pull ring is fixedly connected to the side of the limiting plate away from the upper lifting rod, and a controller is fixedly connected to the front of the box.

[0012] Preferably, a handle is fixedly connected to the top of the box, and the surface of the handle is covered with an anti-slip pad.

[0013] Preferably, a limiting groove is provided on the side of the mounting plate near the upper suspension rod, a column foot is fixedly connected to the bottom of the column, and a clamping block is fixedly connected to the bottom of the column foot.

[0014] A method for using an auxiliary device for tying reinforcing bars in a large-section reinforced concrete beam includes the following steps:

[0015] A. Place the columns on the panels on both sides of the beam formwork and insert the upper hanging rods into the sleeves;

[0016] B. The motor drives the threaded rod to rotate, and the threaded sleeve and moving rod drive the mounting box and all the structures on the mounting box to move towards the side closer to the upper hanging rod, clamping and fixing the upper hanging rod. At this time, the clamping blocks are clamped on both sides of the plate to ensure the stability of the entire device during operation.

[0017] C. Insert the lower suspension rod into the upper main reinforcement of the beam to be tied, and connect the manual hoist and chain to the upper and lower suspension rods through the lifting rings;

[0018] D. Pull the lower boom by the zipper to lift the lower beam reinforcement to a suitable position for tying the bottom beam reinforcement, then stop lifting and begin tying the reinforcement.

[0019] E. After the binding is completed, lower the lower suspension rod, place the beam back on the inner pad block, and pull out the lower suspension rod.

[0020] F. Move the entire device to the next beam for reuse. When the column needs to be replaced, pull the limit plate with the pull ring, and the movable rod will move the locking block out of the slot to replace the column.

It has a simple structure and is easy to use. It solves the problem that when using binding auxiliary devices for large-section beams during construction, workers' arms cannot bind the bottom and web reinforcement bars. Previously, this method required leaving one side of the beam formwork unsupported during formwork erection, only allowing it to be closed after the beam reinforcement binding was completed. This resulted in overlapping work between steelworkers and carpenters, steelworkers working at heights, low construction efficiency, and quality problems in the reinforcement binding, making rectification difficult.
