Description

Technical Field

[0001] The utility model relates to the technical field of rebar planting, in particular to an extended rebar planting that is convenient for installation. Background Art

[0002] The rebar planting technology is a relatively simple and effective connection and anchoring technology for concrete structures; ordinary steel bars or steel screws can be implanted; it has now been widely used in the reinforcement and renovation projects of existing buildings. The chemical method of rebar planting refers to drilling holes in substrates such as concrete and wall rocks, and then injecting high-strength rebar planting glue. After the glue solidifies, the anchor is bonded to the substrate as a whole. During the construction of post-anchored rebar planting, the bonding and fastening degree between the implanted steel bar and the concrete structure plays a decisive role in the anchoring construction.

[0003] For example, Chinese Patent Publication No. CN219754109U discloses an extended rebar planting that is convenient for installation, including: an installation hole, which is located on the wall where the rebar is to be planted and should be kept dry and clean; and further including: a fastener, which is installed at the top of the installation hole and is used to keep the rebar vertical; a rebar, which is installed in the installation hole and is used to reinforce the wall; and an installation auxiliary part, which is used to assist the installation of the rebar. In this utility model, by installing the fastener at the top of the installation hole and then installing the rebar into the fastener, with a threaded connection between the fastener and the rebar, it can ensure that the rebar is inserted into the installation hole in a direction perpendicular to the concrete surface, and the surface of the rebar is evenly wrapped with structural glue, and an installation auxiliary part is also provided.

[0004] However, in the above solution, when rotating the rebar, the fastener is prone to rotate with the rebar. Therefore, it is necessary to manually press and limit the fastener to prevent the fastener from rotating with the rebar, and the convenience is not high. Summary of the Utility Model

[0005] The utility model provides an extended rebar planting that is convenient for installation to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

An external thread is provided on the outer sidewall of the rebar. A limiting tube is threadedly connected to the outer sidewall of the rebar. An annular limiting plate is fixedly connected to the outer sidewall of the limiting tube. The bottom of the annular limiting plate abuts against the top sidewall of the concrete ground. One end of the limiting tube is slidably connected to the top of the planting hole. A limiting structure is provided on the sidewall of the annular limiting plate. A rotating block is threadedly connected to the top of the rebar. A threaded hole is opened at the bottom of the rotating block. Second rotating rods are fixedly connected to both sidewalls of the rotating block.

[0008] As a further improvement of the technical solution: The limiting structure includes a T-shaped rod, which is fixedly connected to the side wall at one end of the top of the annular limiting plate.

[0023] Please refer to Figures 1-3 , in the embodiment of the present utility model, a lengthened rebar implantation device that is easy to install includes a concrete floor 1. A drilled hole 2 is formed in the concrete floor 1. A rebar 3 is slidably connected in the drilled hole 2. An external thread is provided on the outer sidewall of the rebar 3. A limiting tube 4 is threadedly connected to the outer sidewall of the rebar 3. An annular limiting plate 5 is fixedly connected to the outer sidewall of the limiting tube 4. The bottom of the annular limiting plate 5 abuts against the top sidewall of the concrete floor 1. One end of the limiting tube 4 is slidably connected to the top of the drilled hole 2. A limiting structure is provided on the sidewall of the annular limiting plate 5. A rotating block 8 is threadedly connected to the top of the rebar 3. A threaded hole is formed at the bottom of the rotating block 8. Second rotating rods 7 are fixedly connected to both sidewalls of the rotating block 8.

[0024] Please refer to Figures 1-3, the limiting structure includes a T-shaped rod 9, which is fixedly connected to the side wall at one end of the top of the annular limiting plate 5. The outer side wall of the T-shaped rod 9 is slidably connected with a sliding ring 11. The side wall of the sliding ring 11 is fixedly connected with an L-shaped rod 10. The side wall of the annular limiting plate 5 is provided with a limiting hole 13. The L-shaped rod 10 is adapted to the limiting hole 13. The L-shaped rod 10 on the side wall of the annular limiting plate 5 is stuck in the limiting hole 13 on the side wall of another annular limiting plate 5, so as to limit the limiting tube 4, so that when the rebar 3 rotates, the limiting tube 4 will not rotate with the rebar 3.

[0025] Please refer to Figures 1-3 , the top of the L-shaped rod 10 is fixedly connected with a handle 12. By setting the handle 12, it is convenient to take and move the L-shaped rod 10.

[0026] Please refer to Figures 1-2 , both side walls of the limiting tube 4 are fixedly connected with a first rotating rod 6. The two first rotating rods 6 are located above the annular limiting plate 5. By setting the two first rotating rods 6, it is convenient to rotate the limiting tube 4 to make the L-shaped rod 10 close to and aligned with the limiting hole 13 on the side wall of another annular limiting plate 5.

[0027] Please refer to Figures 1-2 , anti-slip patterns are provided on the surfaces of the two first rotating rods 6 and the two second rotating rods 7 to prevent slipping when rotating the two first rotating rods 6 and the two second rotating rods 7.

[0028] The working principle of the present utility model is: by threadedly connecting the limiting tube 4 to the surface of the rebar 3, the limiting tube 4 can be screwed to an appropriate height according to the depth of the planting hole 2. Inject planting glue into the planting hole 2, and then insert the rebar 3 into the planting hole 2 so that one end of the limiting tube 4 is inserted into the planting hole 2, and the annular limiting plate 5 abuts against the top side wall of the concrete floor 1. By making the limiting tube 4 fit with the planting hole 2, the rebar 3 can be kept vertical. Then, the L-shaped rod 10 on the side wall of the annular limiting plate 5 is stuck in the limiting hole 13 on the side wall of another annular limiting plate 5, so as to limit the limiting tube 4. Then, the second rotating rod 7 can be rotated. The second rotating rod 7 drives the rotating block 8 to rotate. When the rotating block 8 is tightened on the top of the rebar 3, it will drive the rebar 3 to rotate, so that the rebar 3 rotates and moves downward in the limiting tube 4. By setting the limiting tube 4, the rebar 3 can move vertically downward. Through the limitation of the L-shaped rod 10, the rebar 3 can keep the limiting tube 4 stable when rotating, so that the limiting tube 4 will not rotate with the rebar 3, and thus the bottom of the rebar 3 is aligned with the bottom of the planting hole 2.

[0029] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and what is described above; however, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
