Description

Technical Field

[0001] This utility model relates to the field of rebar positioning technology, and in particular to a rebar positioning device for precast components. Background Technology

[0002] Reinforcing steel in precast components refers to the steel bars used in precast building components (such as precast wall panels, beams, slabs, columns, etc.). Reinforcing steel is one of the important structural materials in construction. It is usually used to enhance the tensile strength of concrete because concrete itself has good compressive strength but weak tensile strength. By combining reinforcing steel with concrete, the overall strength and durability of the components can be effectively improved.

[0003] In the process of casting and molding precast concrete components, reinforcing bars need to be inserted and arranged inside the precast concrete mold. Often, the ends of the reinforcing bars need to extend outside the mold. When the reinforcing bars are inserted and arranged inside the mold, the lack of fixed connection between the arranged reinforcing bars can easily lead to displacement of the reinforcing bars inside the mold. Especially during the process of pouring concrete into the precast concrete mold, the impact of concrete pouring will exacerbate the displacement of the reinforcing bars. The displacement of the reinforcing bars will cause them to deviate from their intended positions, thereby affecting the tensile strength and load-bearing capacity of the precast concrete component after casting and molding. Therefore, a reinforcing bar positioning device for precast components is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precast component reinforcement positioning device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precast component rebar positioning device includes a first side frame, a second side frame, and rebar bodies. Each of the two first side frames has two side openings. The two ends of the two second side frames are respectively inserted into corresponding side openings in the two first side frames. Each of the two first and second side frames has an installation groove. Multiple installation blocks are movably installed in the multiple installation grooves. Each installation block has a circular hole. Multiple rebar bodies are arranged equidistantly and overlapped. One end of each rebar body passes through the circular hole in the corresponding installation block. The two first side frames and the two second side frames... Both side frames have sliding openings on their top sides. Multiple F-shaped inserts are inserted into the mounting grooves and sliding openings on the first and second side frames. The bottom sides of the multiple F-shaped inserts are respectively attached to the top sides of the corresponding mounting blocks. The F-shaped inserts have slots, and L-shaped positioning plates are movably inserted into the slots of the F-shaped inserts. One side of the L-shaped positioning plate abuts against one end of the reinforcing bar body. The mounting blocks have threaded holes on their top sides, and bolts are provided above the threaded holes. One end of the bolts is threaded into the threaded holes of the mounting blocks.

[0007] Preferably, the two first side frames and the two second side frames are assembled to form a U-shaped structure, which facilitates the assembly and splicing of the two first side frames and the two second side frames around the precast concrete mold.

[0008] Preferably, the sliding openings on the two first side frames are connected to the mounting grooves, and the sliding openings on the two second side frames are connected to the mounting grooves, so that the bolts can pass through the sliding openings.

[0009] Preferably, the number of mounting blocks, F-type inserts, L-type positioning plates, and bolts are all set in the same order.

[0010] Preferably, the bottom end of the bolt is fitted against the top side of the F-type insert plate and the L-type positioning plate and threaded into the threaded hole on the top side of the mounting block; the position of the F-type insert plate, the L-type positioning plate and the mounting block are tightened and fixed by tightening the bolt into the threaded hole on the top side of the mounting block.

[0011] Preferably, two guide grooves are respectively opened in the two side openings of the first side frame, and the same clamping plate is movably installed in the two guide grooves of the side opening. One side of the clamping plate is attached to one side of the second side frame, and one end of a threaded rod is rotatably installed on one side of the clamping plate. The other end of the threaded rod is threaded through to the outside of the first side frame and fixedly installed with a handle plate; this facilitates the positioning of the two first side frames and two second side frames after the precast concrete component mold is assembled and spliced ​​around it.

[0012] The beneficial effects of this utility model are as follows: This precast component rebar positioning device, by adjusting multiple sets of clamping plates, assembles and splices two first side frames and two second side frames around the perimeter of the precast concrete mold and fixes their positions. The bottom side of the F-shaped insert plate is attached to the top side of the mounting block. The L-shaped positioning plate is inserted into the slot of the F-shaped insert plate, so that one side of the L-shaped positioning plate is attached to one end of the rebar body. By screwing on multiple sets of F-shaped insert plates, L-shaped positioning plates and bolts, the two ends of multiple rebar bodies extending out of the precast concrete mold are positioned, clamped and fixed. This avoids the rebar bodies of the interlocking arrangement from being displaced by the impact of concrete pouring during the subsequent pouring of concrete into the precast concrete mold, and ensures that the interlocking rebar bodies do not deviate from their predetermined positions during concrete pouring, thus improving the practicality of the precast component rebar positioning device.

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] Reference Figure 1-6 A precast component rebar positioning device includes a first side frame 1, a second side frame 2, and rebar bodies 3. Each of the two first side frames 1 has two side openings 4. The two ends of the two second side frames 2 are respectively inserted into corresponding side openings 4 within the two first side frames 1. Each of the two first side frames 1 and the two second side frames 2 has an installation groove 5. Multiple installation blocks 6 are movably installed within the multiple installation grooves 5. Each of the multiple installation blocks 6 has a circular hole 7. Multiple rebar bodies 3 are arranged equidistantly and overlapped. One end of each rebar body 3 passes through the circular hole 7 in the corresponding installation block 6. The two first side frames 1 and the two second side frames 2... Both sides of the frame 2 have a sliding opening 8 on their top sides. Multiple F-shaped insert plates 9 are inserted into the mounting grooves 5 and sliding openings 8 on the first side frame 1 and the second side frame 2. The bottom sides of the multiple F-shaped insert plates 9 are respectively attached to the top side of the corresponding mounting block 6. The F-shaped insert plates 9 have slots 10. An L-shaped positioning plate 11 is movably inserted into the slots 10 of the F-shaped insert plates 9. One side of the L-shaped positioning plate 11 abuts against one end of the steel bar body 3. The top side of the mounting block 6 has a threaded hole 12. A bolt 13 is provided above the threaded hole 12. One end of the bolt 13 is threaded into the threaded hole 12 of the mounting block 6.

[0022] Furthermore, the two first side frames 1 and the two second side frames 2 are assembled to form a U-shaped structure, which facilitates the assembly and splicing of the two first side frames 1 and the two second side frames 2 around the precast concrete mold.

[0023] Specifically, the sliding openings 8 on the two first side frames 1 are connected to the mounting grooves 5, and the sliding openings 8 on the two second side frames 2 are connected to the mounting grooves 5, so that the bolts 13 can pass through the sliding openings 8.

[0024] Furthermore, the number of mounting blocks 6, F-type inserts 9, L-type positioning plates 11, and bolts 13 are set consistently.

[0025] Specifically, the bottom end of the bolt 13 is fitted against the top side of the F-type insert plate 9 and the L-type positioning plate 11 and threaded into the threaded hole 12 on the top side of the mounting block 6; the position of the F-type insert plate 9, the L-type positioning plate 11 and the mounting block 6 are tightened and fixed by tightening the bolt 13 into the threaded hole 12 on the top side of the mounting block 6.

[0026] Furthermore, two guide grooves 14 are respectively opened in the two side openings 4 of the first side frame 1. The same clamping plate 15 is movably installed in the two guide grooves 14 of the side opening 4. One side of the clamping plate 15 is attached to one side of the second side frame 2. One end of the threaded rod 16 is rotatably installed on one side of the clamping plate 15. The other end of the threaded rod 16 is threaded through to the outside of the first side frame 1 and fixedly installed with a handle plate 17. This facilitates the positioning of the two first side frames 1 and the two second side frames 2 after the precast concrete mold is assembled and spliced ​​around it.

[0027] In use: During the process of arranging the reinforcing bar body 3 inside the precast concrete mold, the two ends of the reinforcing bar body 3 extending outside the precast mold pass through the corresponding round holes 7 in the mounting block 6. After the reinforcing bar body 3 is inserted and arranged inside the precast mold, the workers assemble the two first side frames 1 and the two second side frames 2 into a U-shape and fit them against the perimeter of the precast mold. By turning the handle disc 17 on the adjusting threaded rod 16 in sequence, one side of each of the multiple clamping plates 15 is pressed against one side of the second side frame 2, thereby fixing the position of the assembled two first side frames 1 and two second side frames 2. Then, the F-shaped insert plate 9 is inserted into the mounting groove 5 and sliding opening 8 on the top side of the first side frame 1, so that the bottom side of the F-shaped insert plate 9 fits against the top side of the mounting block 6. Then, the L-shaped positioning plate 11 is inserted into the slot 10 of the F-shaped insert plate 9, so that one side of the L-shaped positioning plate 11 fits against the reinforcing bar body. One end of the bolt 13 is then passed through the F-type insert plate 9 and the L-type positioning plate 11 and threaded into the threaded hole 12 on the top side of the mounting block 6. The bolt 13 is tightened into the threaded hole 12 on the top side of the mounting block 6 to tighten and fix the position of the F-type insert plate 9, the L-type positioning plate 11 and the mounting block 6. The operation is repeated. By screwing multiple sets of F-type insert plates 9, L-type positioning plates 11 and bolts 13, the two ends of the multiple steel bar bodies 3 extending out of the concrete precast mold are positioned, clamped and fixed. This prevents the steel bar bodies 3 from being displaced by the impact of concrete pouring into the concrete precast mold. It also ensures that the steel bar bodies 3 do not deviate from the predetermined position during the concrete pouring process, improves the practicality of the precast component steel bar positioning device, and also ensures the tensile strength and load-bearing capacity of the precast concrete after casting.
