Description

Technical Field

[0001] This utility model relates to the field of building industry technology, specifically to a precast column rebar positioning plate device. Background Technology

[0002] In the process of industrialized construction, prefabricated assembly structures have been widely used due to their advantages such as high construction efficiency and controllable quality. As core vertical load-bearing components, the positioning accuracy of the reinforcing bars in prefabricated columns directly affects the overall structural performance. Traditional prefabricated column construction typically uses fixed reinforcing bar positioning plates, achieving bar positioning through pre-set holes. However, due to inherent dimensional errors in prefabricated columns and the possibility of slight offsets during on-site hoisting, alignment between the reinforcing bars and the positioning holes becomes difficult, potentially leading to bar deformation or positioning failure. Existing technologies include some adjustable positioning devices that adjust hole positions via bolts, but the adjustment process is cumbersome and lacks a quick locking mechanism, making it difficult to efficiently adapt to prefabricated columns of different sizes during construction. Utility Model Content

[0003] The purpose of this utility model is to provide a precast column rebar positioning plate device, which solves the problem of difficulty in aligning the rebar with the positioning hole by means of a sliding U-shaped plate and a threaded rod locking mechanism.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model is a precast column rebar positioning plate device, including a positioning plate body. A positioning component is provided on the top of the positioning plate body. The positioning component has a first U-shaped plate, a second U-shaped plate and threaded rods. First rectangular plates are installed on both sides of the first U-shaped plate. Through holes are opened on both first rectangular plates. Second rectangular plates are installed on both sides of the second U-shaped plate. Threaded holes are opened on both second rectangular plates. There are two threaded rods. The two threaded rods pass through the corresponding through holes and are threaded into the corresponding threaded holes.

[0006] Furthermore, L-shaped blocks are installed on both sides of the bottom of the first and second U-shaped plates, and L-shaped grooves are opened on both sides of the top of the positioning plate body. The four L-shaped blocks are slidably fitted into the corresponding L-shaped grooves.

[0007] Furthermore, a partition block is installed in the middle of both L-shaped grooves.

[0008] Furthermore, the positioning plate body is composed of an upper plate, a lower plate, and ribs. The upper plate and the lower plate are arranged in parallel, and the ribs are arranged vertically between the upper plate and the lower plate.

[0009] Furthermore, a pre-drilled hole is provided in the middle of the upper plate, and multiple positioning holes are provided in the middle of the lower plate.

[0010] Furthermore, angle steel is installed at each of the four corners between the upper and lower plates.

[0011] This utility model has the following beneficial effects:

[0012] This utility model, through the design of a first U-shaped plate, a second U-shaped plate, and a threaded rod, can flexibly adapt to precast columns of different sizes. During operation, simply slide the U-shaped plate to make it fit against the surface of the precast column, and then rotate the threaded rod to bring the first rectangular plate and the second rectangular plate closer together to achieve quick locking. This not only improves clamping stability and prevents the precast column from shifting during hoisting, but also simplifies the adjustment steps, significantly improves construction efficiency, and ensures that the reinforcing bars can be accurately aligned with the positioning holes of the lower plate, thereby improving the installation accuracy of the precast column.

[0013] This utility model uses an L-shaped block to allow the U-shaped plate to slide along the L-shaped groove of the positioning plate body and to be easily disassembled after construction. The partition block set in the L-shaped groove can limit the movement range of the U-shaped plate and prevent excessive sliding from affecting the clamping effect. This makes the device highly reusable, easy to transport and store, and reduces on-site assembly time, improving construction convenience. It is especially suitable for construction scenarios of prefabricated components that require frequent disassembly and assembly.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a precast column rebar positioning plate device, including a positioning plate body 1, which is composed of an upper plate 9, a lower plate 10, and ribs 11. The ribs 11 can improve the overall structural strength. The upper plate 9 and the lower plate 10 are arranged in parallel, and the ribs 11 are arranged vertically between the upper plate 9 and the lower plate 10. A reserved hole 103 is opened in the middle of the upper plate 9 for the insertion of rebar or other components. A plurality of positioning holes 102 are opened in the middle of the lower plate 10. Angle steel 12 is installed at the four corners between the upper plate 9 and the lower plate 10. The angle steel 12 can further enhance the rigidity and stability of the device. When the positioning plate body 1 is used, the precast column is hoisted above the positioning plate body 1, so that the rebar of the precast column is initially aligned with the positioning hole 102 of the lower plate 10. After the precast column is fixed by the positioning components, the rebar can be accurately inserted into the positioning hole 102 to complete the positioning.

[0022] A positioning assembly is provided on the top of the positioning plate body 1. The positioning assembly is used to clamp the precast column and adjust its position. The positioning assembly has a first U-shaped plate 2, a second U-shaped plate 3, and threaded rods 6. The first U-shaped plate 2 and the second U-shaped plate 3 are made of high-strength steel plates. A first rectangular plate 4 is installed on both sides of the first U-shaped plate 2. A through hole 401 is opened on both of the two first rectangular plates 4. A second rectangular plate 5 is installed on both sides of the second U-shaped plate 3. A threaded hole 501 is opened on both of the two second rectangular plates 5. There are two threaded rods 6. The threaded rods 6 pass through the corresponding through holes 401 and are threaded into the corresponding threaded holes 501. After the precast column is hoisted onto the positioning plate body 1, the operator slides the first U-shaped plate 2 and the second U-shaped plate 3, so that they move closer to the precast column along the L-shaped groove 101 until the inner sides of the first U-shaped plate 2 and the second U-shaped plate 3 contact the surface of the precast column. Then, the two threaded rods 6 are rotated so that the first rectangular plate 4 and the second rectangular plate 5 move closer to each other, thereby driving the first U-shaped plate 2 and the second U-shaped plate 3 to clamp the precast column and ensure its stable position.

[0023] L-shaped blocks 7 are installed on both sides of the bottom of the first U-shaped plate 2 and the second U-shaped plate 3. L-shaped grooves 101 are opened on both sides of the top of the positioning plate body 1. The four L-shaped blocks 7 are slidably fitted in the corresponding L-shaped grooves 101. A partition block 8 is installed in the middle of the two L-shaped grooves 101. When the first U-shaped plate 2 and the second U-shaped plate 3 are moved, the L-shaped blocks 7 move along the L-shaped grooves 101 until they contact the partition block 8. The partition block 8 can prevent the U-shaped plate from moving excessively and ensure that the clamping force is evenly distributed. After the construction is completed, the threaded rod 6 is rotated in the opposite direction to release the clamping of the precast column and pull the U-shaped plate to both sides so that the L-shaped blocks 7 slide out of the L-shaped grooves 101. The U-shaped plate can then be disassembled, which facilitates the reuse of the device. The device has a simple structure and is easy to adjust, which can effectively improve the installation accuracy and construction efficiency of the precast column.
