Description

Technical Field

[0001] This utility model relates to the field of rebar positioning technology, specifically to a rebar positioning device for building construction. Background Technology

[0002] With the continuous development of construction technology, higher requirements have been placed on the quality and efficiency of column reinforcement binding. On the one hand, building structures are becoming increasingly complex, demanding higher precision in the arrangement and binding of column reinforcement. For example, in high-rise buildings, large-span buildings, and buildings with high seismic resistance requirements, the accurate binding of column reinforcement plays a decisive role in the seismic performance and load-bearing capacity of the structure. On the other hand, in order to improve construction efficiency and shorten the construction period, more advanced technologies and equipment are needed to improve the column reinforcement binding process.

[0003] Current methods for binding column reinforcement are inadequate. They mainly rely on positioning devices to locate four column reinforcement bars simultaneously. However, due to the toughness of the reinforcement bars, existing positioning devices require workers to position the bars in multiple segments, increasing the difficulty of column reinforcement and affecting the work efficiency of workers. Therefore, a new column reinforcement bar positioning device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar positioning device for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a rebar positioning device for building construction, comprising a housing, an L-shaped connecting plate fixedly connected to one side edge of the housing near the middle of the bottom side, an arc-shaped feeding plate fixedly connected between one side inner wall of the housing and one side of the L-shaped connecting plate, a sliding assembly provided between one side inner wall of the housing and the L-shaped connecting plate, the sliding assembly including two sliding rods, the two ends of the two sliding rods respectively fixedly connected to one side inner wall of the housing and one side of the L-shaped connecting plate, and the two sliding rods being arranged away from each other, a one-way threaded rod rotatably connected between one side inner wall of the housing and the L-shaped connecting plate, a sliding plate slidably installed on the outer side of the two sliding rods, and the sliding plate being threadedly connected to the one-way threaded rod, a positioning plate fixedly connected to the top side of the sliding plate, and a plurality of sliding holes provided on one side of the positioning plate, the plurality of sliding holes being arranged in an X shape.

[0006] As a further improvement to this technical solution, a drive motor is fixedly installed on the other side of the L-shaped connecting plate. The output shaft of the drive motor passes through the L-shaped connecting plate, and the output shaft of the drive motor is fixedly connected to one end of the one-way threaded rod. The drive motor drives the one-way threaded rod to rotate between the housing and the L-shaped connecting plate, thereby causing the sliding plate to slide on the outside of the two sliding rods.

[0007] As a further improvement to this technical solution, a clamping assembly is provided on the L-shaped connecting plate. The clamping assembly includes a clamping plate, which is fixedly connected to the top side of the L-shaped connecting plate. A plurality of clamping holes are provided on one side of the clamping plate, and the plurality of clamping holes are arranged in an X-shape. A fixing block is fixedly connected to one side of the clamping plate near the four corners. A rotating screw is threaded onto the fixing block. An arc-shaped rotating plate is rotatably connected to one end of the rotating screw. An arc-shaped clamping plate is fixedly connected to the inner side of the arc-shaped rotating plate.

[0008] As a further improvement to this technical solution, the multiple positioning plates on the positioning plate correspond to the multiple clamping holes on the clamping plate. Rotating the rotating screw squeezes and fixes the reinforcing bar in the clamping hole through the arc-shaped rotating plate and the arc-shaped clamping plate.

[0009] As a further improvement to this technical solution, when the arc-shaped rotating plate and the arc-shaped clamping plate move, the clamping plate limits the arc-shaped rotating plate and the arc-shaped clamping plate, so that the arc-shaped rotating plate and the arc-shaped clamping plate move along one side of the clamping plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In the rebar positioning device for building construction, multiple rectangular fixed rebars are placed between a positioning plate and a clamping plate. Four columnar rebars are then passed through sliding holes on the positioning plate and clamping holes on the clamping plate, respectively. Simultaneously, the columnar rebars are positioned among the multiple fixed rebars. Rotating multiple rotating screws drives an arc-shaped rotating plate and an arc-shaped clamping plate to compress and fix one end of the columnar rebars. Then, workers tie the fixed rebars to the four columnar rebars. A drive motor drives a one-way threaded rod to rotate, causing the sliding plate to move to one side outside the two sliding rods. At the same time, the four columnar rebars slide within the sliding holes, avoiding the impact of the columnar rebars' toughness on the tying efficiency. Attached Figure Description

A sliding component 4 is provided between one side inner wall of the housing 1 and the L-shaped connecting plate 2. The sliding component 4 is used to support the column rebar and avoid the difficulty of binding the column rebar due to the toughness of the column rebar, which affects the efficiency of the workers. The sliding component 4 includes two sliding rods 41. The two ends of the two sliding rods 41 are respectively fixedly connected to one side inner wall of the housing 1 and one side of the L-shaped connecting plate 2. At the same time, the two sliding rods 41 are set away from each other. A one-way threaded rod 42 is rotatably connected between one side inner wall of the housing 1 and the L-shaped connecting plate 2. A sliding plate 43 is slidably installed on the outer side of the two sliding rods 41. The two sliding rods 41 are used to limit the sliding plate 43. Simultaneously, it ensures that the sliding plate 43 can slide stably on the outside of the two sliding rods 41, and the sliding plate 43 is threadedly connected to the one-way threaded rod 42. Through the threaded connection between the one-way threaded rod 42 and the sliding plate 43, the one-way threaded rod 42 drives the sliding plate 43 to slide on the outside of the two sliding rods 41. A positioning plate 44 is fixedly connected to the top side of the sliding plate 43. Multiple sliding holes 45 are opened on one side of the positioning plate 44. The multiple sliding holes 45 are arranged in an X shape. Through the multiple sliding holes 45 on the positioning plate 44 It can limit the column reinforcement, and the column reinforcement slides in the sliding hole 45. A drive motor 46 is fixedly installed on the other side of the L-shaped connecting plate 2. The output shaft of the drive motor 46 passes through the L-shaped connecting plate 2, and the output shaft of the drive motor 46 is fixedly connected to one end of the one-way threaded rod 42. The drive motor 46 drives the one-way threaded rod 42 to rotate between the housing 1 and the L-shaped connecting plate 2, which drives the sliding plate 43 to slide outside the two sliding rods 41, thereby driving the positioning plate 44 on the sliding plate 43 to move.

[0020] Please see Figure 3As shown, the L-shaped connecting plate 2 is equipped with a clamping assembly 5. The clamping assembly 5 can clamp and fix one end of the column reinforcement, allowing the column reinforcement to slide within the sliding hole 45. The clamping assembly 5 includes a clamping plate 51, which is fixedly connected to the top side of the L-shaped connecting plate 2. Multiple clamping holes 52 are opened on one side of the clamping plate 51, and the multiple clamping holes 52 are arranged in an X shape.

Rotating screws 54 are threaded onto the fixing blocks 53, and one end of the rotating screws 54 is rotatably connected to... An arc-shaped rotating plate 55 is connected to the inside of the arc-shaped rotating plate 55, and an arc-shaped clamping plate 56 is fixedly connected to the inside of the arc-shaped rotating plate 55. When the arc-shaped rotating plate 55 and the arc-shaped clamping plate 56 move, the clamping plate 51 limits the arc-shaped rotating plate 55 and the arc-shaped clamping plate 56, so that the arc-shaped rotating plate 55 and the arc-shaped clamping plate 56 move along one side of the clamping plate 51. The multiple positioning plates 44 on the positioning plate 44 correspond to the multiple clamping holes 52 on the clamping plate 51. The rotating screw 54 is rotated to squeeze and fix the steel bar in the clamping hole 52 through the arc-shaped rotating plate 55 and the arc-shaped clamping plate 56.

[0021] In practical use, the rebar positioning device of this embodiment first connects the power supply to the rebar positioning device, places multiple rectangular fixed rebars between the positioning plate 44 and the clamping plate 51, and then passes four column rebars through the sliding holes 45 on the positioning plate 44 and the clamping holes 52 on the clamping plate 51 respectively. At the same time, the column rebars are located between multiple fixed rebars. Rotating multiple rotating screws 54 drives the arc-shaped rotating plate 55 and the arc-shaped clamping plate 56 to squeeze and fix one end of the column rebars. Then, the fixed rebars are tied to the four column rebars by the workers. Then, the drive motor 46 drives the one-way threaded rod 42 to rotate, so that the sliding plate 43 moves to one side outside the two sliding rods 41, and at the same time, the four column rebars slide in the sliding holes 45 to avoid the toughness of the column rebars affecting the efficiency of tying.
