Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering construction, and more specifically to the technical field of a steel bar bending device at a location where the space of a prefabricated component is limited. Background Art
[0002] Prefabricated components have been used in engineering construction since the 1920s, and my country also began researching and applying prefabricated components in the 1960s. Prefabricated components have become an indispensable part of the engineering construction industry.
[0003] After the prefabricated columns are installed, the main reinforcement is deformed due to surrounding construction or production and processing, making it difficult to install the next layer of prefabricated columns and to adjust the reinforcement. Due to the influence of the beam reinforcement, the composite slab will bend one side of the reinforcement during installation. After it is put in place, the reinforcement will be straightened. Because the reinforcement needs to be adjusted to the inside of the beam, the site often uses the method of "smashing" it straight with external objects. This method has poor straightening effect and will damage the concrete under the reinforcement, which has a great impact on the quality of the project. Utility Model Content
[0004] The purpose of the utility model is to solve the technical problem that it is difficult to bend and straighten steel bars in confined spaces, and to provide a steel bar bending device for prefabricated components in confined spaces, which can effectively avoid damage to surrounding concrete during the steel bar bending process and improve the quality of construction projects.
[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0006] The present embodiment provides a steel bar bending device for a prefabricated component at a space-constrained location, comprising a vertical pole assembly, a fixed plate assembly arranged at the bottom of the vertical pole assembly, a ratchet sleeve movably mounted on the fixed plate assembly, and an elastic fine-tuning assembly for locking the ratchet sleeve on the fixed plate assembly.
[0007] Specifically, when adjusting the steel bar, the fulcrum is on the steel bar itself to avoid damage to the surrounding concrete; the device can bend the steel bar in a space-constrained area, and has a simple structure, is easy to produce, and is convenient and quick to use. It increases the construction speed while ensuring the quality of the project. All parts are assembled in the factory and can be used directly on site.
[0008] In one embodiment, the pole assembly includes a pole component one, a pole component two, and a pole component three that are sequentially connected from top to bottom, and the fixing plate assembly is fixedly installed below the pole component three.

[0010] In one embodiment, the end faces of the first and second vertical pole components are welded, and a cap handle for fixing the left and right adjustment rods is sleeved between the first and second vertical pole components.
[0011] Specifically, a cap handle is provided on the top of the device, which can be used with a ratchet sleeve to achieve left and right micro-movement; it has a wide range of uses and can be used not only to bend steel bars, but also other long objects.
[0012] In one embodiment, the tops of the left and right adjustment rods are hinged to the top side walls of the strip-shaped through slots via adjustment pins, and the magnetic unit is a magnet.
[0013] Specifically, the magnets are installed on the side wall at the bottom of the strip-shaped through slot of the second vertical pole component and the bottom of the left and right adjustment rods as required. The left and right adjustment rods are placed as required, the adjustment pins are inserted, and the cap handles are installed to fix them.

[0015] Specifically, the first upright pole component, the second upright pole component, the third upright pole component, the first fixing plate and the second fixing plate are welded into a whole.
[0016] In one embodiment, the ratchet sleeve includes a sleeve that cooperates with the steel bar and is open in the axial direction, and a ratchet arranged in the middle of the outer wall of the sleeve, and a mounting hole is opened in the center of the ratchet. The ratchet is movably installed between the fixed plate one and the fixed plate two through a main pin shaft passing through the mounting hole.
[0017] In one embodiment, the elastic fine-tuning component includes two clamping blocks movably mounted on a fixed plate one via a clamping block pin, a tension spring connected between the two clamping blocks, a converter movably mounted on the fixed plate one via a converter pin (14), and a square sleeve fixing piece installed near one side of the tension spring to limit the displacement of the converter, the converter cooperates with the two clamping blocks, and the two clamping blocks cooperate with the ratchet.
[0018] Specifically, this device can achieve micro-movement of the steel bars up and down, and left and right adjustments. When micro-moving up and down, the vertical pole can be adjusted by swinging in a small range. The required space for movement is extremely small.
