Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering repair technology, and in particular to a foldable template device for repairing penetrating holes after core sampling of concrete components. Background Technology
[0002] In the process of quality inspection of building engineering, it is often necessary to take core samples from concrete components. In some cases, it is necessary to penetrate the component for testing. After the core sample is taken, the component needs to be repaired in a timely manner to avoid affecting the structural stability and aesthetics of the component.
[0003] In existing technologies, the repair of core holes in concrete components is usually carried out by directly pouring mortar, concrete or other repair materials into the hole. However, for penetrating holes, if there is no formwork support, the repair material is easy to leak out, which not only wastes materials but also affects the repair quality, resulting in defects such as hollowness and lack of density in the repaired hole. Utility Model Content
[0004] The purpose of this utility model is to provide a foldable template device for repairing through holes after core sampling of concrete components, so as to solve the problem mentioned in the background art that the repair material is easy to leak out, which not only causes material waste, but also affects the repair quality and leads to defects such as hollowness and lack of density in the repaired hole.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a concrete mechanism, the concrete mechanism comprising a concrete component, a sampling port and a positioning hole, a positioning mechanism provided inside one side of the concrete mechanism, the positioning mechanism comprising a disc, a through hole, a first sealing ring, a positioning plate and a steel nail, and a folding template mechanism provided inside the other side of the concrete mechanism, the folding template mechanism comprising a fan-shaped petal, an elastic hinge, a second sealing ring and a traction line.
[0006] In a preferred embodiment, a sampling port is provided inside the concrete component, and a positioning hole is provided on one side of the concrete component.
[0007] In a preferred embodiment, the inner wall of the sampling port near the positioning hole is movable with the outer wall of the disk, and the disk has a through hole inside.
[0008] In a preferred embodiment, the outer wall of the disc is fixedly connected to the inner wall of the first sealing ring, and the outer wall of the disc is fixedly connected to the inner wall of the positioning disc.
[0009] In a preferred embodiment, the inner wall of the positioning disc is movably connected to the outer wall of the steel nail, and one side of the positioning disc is movably abutting against one side of the concrete component.
[0010] In a preferred embodiment, the inner wall of the sampling port on the side away from the positioning hole is movably connected to the outer wall of the fan-shaped valve body. The fan-shaped valve body is provided in four sets, and the four sets of fan-shaped valve bodies are movably connected to each other by elastic hinges.
[0011] In a preferred embodiment, the outer wall of the fan-shaped valve is movably connected to the inner wall of the second sealing ring, and one side of the fan-shaped valve is fixedly connected to one end of the traction line.
[0012] In a preferred embodiment, the traction wire may penetrate the interior of the sampling port, and the traction wire may pass through the inner wall of the through hole.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the initial state of the fan-shaped petal is adjusted to a retracted state. The fan-shaped petal is retracted by an elastic hinge, allowing it to enter the sampling port. The fan-shaped petal reaches the side of the sampling port away from the positioning hole. The traction line is passed through the through hole, and then the disc is placed inside the sampling port. At the same time, the positioning disc blocks the concrete component near the positioning hole. Then, steel nails are inserted into the positioning hole to fix the positioning disc. Then, the traction line is pulled, causing the fan-shaped petal to unfold. The unfolded fan-shaped petal is stabilized on the inner wall of the sampling port away from the positioning hole by the compression of the second sealing ring. Then, the traction line is tied to the steel nail, and concrete is injected into the sampling port. The disc and the fan-shaped petal block the leakage of repair material, ensuring the quality of the repair.
[0014] 2. In this utility model, after the disc is installed, the first sealing ring contacts the inner wall of the sampling port, and after the fan-shaped petal body is unfolded, the second sealing ring contacts the inner wall of the sampling port. The sealing effect after the disc and the fan-shaped petal body are installed is ensured by setting the first sealing ring and the second sealing ring. Attached Figure Description

[0017] 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.
[0018] Please see Figures 1-5 This utility model provides a technical solution comprising: a concrete mechanism 1, which includes a concrete component 101, a sampling port 102, and a positioning hole 103. A positioning mechanism 2 is provided inside one side of the concrete mechanism 1, which includes a disc 201, a through hole 202, a first sealing ring 203, a positioning plate 204, and a steel nail 205. A folding template mechanism 3 is provided inside the other side of the concrete mechanism 1, which includes a fan-shaped petal 301, an elastic hinge 302, a second sealing ring 303, and a traction line 304.
[0019] In one embodiment, a sampling port 102 is provided inside the concrete component 101, and a positioning hole 103 is provided on one side of the concrete component 101.
[0020] Specifically: Use steel nails 205 to insert into the positioning hole 103 to fix the positioning plate 204.
[0021] In one embodiment, the inner wall of the sampling port 102 near the positioning hole 103 is movable to the outer wall of the disc 201. The disc 201 has a through hole 202 inside. The outer wall of the disc 201 is fixedly connected to the inner wall of the first sealing ring 203. The outer wall of the disc 201 is fixedly connected to the inner wall of the positioning disc 204. The inner wall of the positioning disc 204 is movably connected to the outer wall of the steel nail 205. One side of the positioning disc 204 is movably abutting against one side of the concrete component 101.
[0022] Specifically: the disc 201 is placed inside the sampling port 102, while the positioning disc 204 blocks the concrete component 101 on the side near the positioning hole 103. Then, steel nails 205 are inserted into the positioning hole 103 to fix the positioning disc 204, and the traction line 304 can be tied above the steel nails 205.
[0023] In one embodiment, the inner wall of the sampling port 102 away from the positioning hole 103 is movably connected to the outer wall of the fan-shaped valve body 301. There are four sets of fan-shaped valve bodies 301, and the four sets of fan-shaped valve bodies 301 are movably connected to each other by elastic hinges 302. The outer wall of the fan-shaped valve body 301 is movably connected to the inner wall of the second sealing ring 303. One side of the fan-shaped valve body 301 is fixedly connected to one end of the traction line 304. The traction line 304 can pass through the interior of the sampling port 102 and can pass through the inner wall of the through hole 202.
[0024] Specifically: the leakage of repair material is reduced by the blocking of the disc 201 and the fan-shaped petal 301, thus ensuring the quality of the repair. The setting of the first sealing ring 203 and the second sealing ring 303 ensures the sealing effect after the disc 201 and the fan-shaped petal 301 are installed.
[0025] Working principle: The initial state of the fan-shaped petal 301 is adjusted to a retracted state. The fan-shaped petal 301 is retracted through the elastic hinge 302, allowing it to enter the sampling port 102. The fan-shaped petal 301 reaches the side of the sampling port 102 away from the positioning hole 103. The traction wire 304 is passed through the through hole 202. Then, the disc 201 is placed inside the sampling port 102. Simultaneously, the positioning disc 204 blocks the concrete component 101 from approaching the positioning hole 103. On one side, steel nails 205 are inserted into the positioning hole 103 to fix the positioning plate 204. Then, the traction line 304 is pulled to make the fan-shaped petal 301 unfold. The unfolded fan-shaped petal 301 is stabilized on the inner wall of the sampling port 102 away from the positioning hole 103 by the compression of the second sealing ring 303. Then, the traction line 304 is tied to the steel nail 205 and concrete is injected into the sampling port 102. After the injection is completed, the inside of the through hole 202 is plugged with a sealing rubber plug to ensure a seal.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
