Description

Technical Field

[0001] The utility model relates to the technical field of steel bar positioning, in particular to a shear wall horizontal steel bar positioning fixture. Background Art

[0002] Shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. They are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. Shear walls are usually cast with reinforced concrete. When tying the steel bars, the steel bars need to be positioned. However, the existing steel bar positioning fixtures are not convenient for adjusting the distance between the steel bars, which is not convenient for the staff to use. In addition, the fixing effect of the steel bars is not very good, which causes the steel bars to deviate during the positioning process, thereby affecting the measurement accuracy. Utility Model Content

[0003] The utility model provides a shear wall horizontal steel bar positioning fixture to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A shear wall horizontal steel bar positioning fixture includes a base, a driving assembly, and a movable plate. The base includes a support plate, and the driving assembly includes a bidirectional threaded rod. The bidirectional threaded rod is movably connected to the inside of the support plate. The outer wall in the middle of the bidirectional threaded rod is fixedly connected to a second gear. The inside of the base is movably connected to a rack.

The movable plate is movably connected to both ends of the bidirectional threaded rod. The movable plate includes a jacket. The upper surface of the base is provided with a groove.

[0006] A further improvement of the technical solution of the utility model is that a bearing is provided inside the support plate, and the bidirectional threaded rod is fixedly connected to the inside of the inner ring of the bearing.

[0007] By adopting the above technical solution, the bidirectional threaded rod in the solution can rotate freely under the action of the bearing.

[0008] A further improvement of the technical solution of the utility model is that: the first gear is meshed with the rack, the rack is meshed with the second gear, a slide groove is provided on the upper surface of the base, and the rack is slidably connected to the inside of the slide groove.

[0009] By adopting the above technical solution, when the first gear in the solution rotates, it can drive the rack to slide up and down inside the slide groove, thereby driving the second gear to rotate.

[0010] A further improvement of the technical solution of the utility model is that a thread groove is opened inside the movable plate, the thread groove is meshed with the thread pattern of the bidirectional threaded rod, and the movable plate is threadedly meshed with the outer walls at both ends of the bidirectional threaded rod through the thread groove.

[0011] By adopting the above technical solution, when the bidirectional threaded rod in the solution rotates, the movable plate can be driven to move relatively under the action of the thread groove threads engaging with the two ends of the bidirectional threaded rod, thereby adjusting the position of the clamped steel bars, which is convenient for the staff to use.

[0012] A further improvement of the technical solution of the utility model is that: a guide block is fixedly connected to the bottom of the movable plate, guide grooves are opened at both ends of the upper surface of the base, and the guide block is slidably connected to the inside of the guide groove.

[0013] By adopting the above technical solution, the guide block and the guide groove in the solution can play a limiting role, so that the movable plate will not be rotated along with the bidirectional threaded rod, thereby performing linear sliding motion.

[0014] A further improvement of the technical solution of the utility model is that the jacket is movably connected to the upper and lower ends of the front and rear ends of the movable plate, the upper and lower ends of the front and rear ends of the movable plate are provided with movable grooves, the movable grooves are symmetrically arranged, and the jacket is slidably connected to the movable grooves.

[0016] By adopting the above technical solution, the limiting groove and the limiting block in the solution can play a limiting role, so that the jacket can perform linear sliding motion inside the movable groove.

[0017] A further improvement of the technical solution of the utility model is that: one end of the return spring away from the jacket is fixedly connected to the inner wall of the movable groove, and the upper end of the jacket is fixedly connected to a pull rod, and the pull rod extends to the outer wall of the movable plate.

The pull rod is used to pull the sleeve to loosen the steel bar.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a shear wall horizontal steel bar positioning fixture, which drives the first gear to rotate through a driving motor to drive the rack to slide up and down, thereby driving the second gear to rotate. When the bidirectional threaded rod rotates, the movable plate can be driven to move relatively under the action of the thread groove thread meshing with the two ends of the bidirectional threaded rod, thereby adjusting the position of the clamped steel bar, which is convenient for the staff to use.

[0021] 2. The utility model provides a shear wall horizontal steel bar positioning fixture, which drives the sleeves to move away from each other by pulling the pull rod, and then places the steel bar between the two sleeves. Then, the pull rod is loosened to allow the reset spring to drive the sleeve to perform a reset movement, so that the sleeve moves in the direction of the relative sleeve, thereby clamping and fixing the steel bar to prevent the steel bar from deviating during the positioning process, thereby ensuring the accuracy of the measurement.

[0034] In this embodiment, the first gear 108 is driven to rotate by the driving motor 107 to drive the rack 105 to slide up and down, thereby driving the second gear 202 to rotate. When the bidirectional threaded rod 201 rotates, it can drive the movable plate 3 to move relative to each other under the action of the thread groove 302 threadedly engaged with the two ends of the bidirectional threaded rod 201, thereby adjusting the position of the clamped steel bars for convenience of use by the staff.

When the first gear 108 rotates, it can drive the rack 105 to slide up and down inside the slide groove 106, thereby driving the second gear 202 to rotate.
