Description

Technical Field

[0001] The utility model relates to the technical field of concrete local structure repair, in particular to a flattening mechanism for local repair materials of concrete structures. Background Technique

[0002] Self-healing concrete imitates the regeneration and recovery mechanism of the bone tissue structure of animals after being traumatized. It is a new composite material that uses the method of compounding repair adhesives and concrete materials to have the functions of self-repairing and regeneration of material damage and can restore or even improve the material properties. Strictly speaking, self-healing concrete should be a kind of smart concrete. Smart concrete is a kind of concrete with sensing and repair properties. It is the primary stage of intelligent concrete and the advanced stage of the development of concrete materials. After cracks and damages occur in the concrete structure constructed by this material, how to utilize its own material characteristics to achieve self-repair and self-passivation and play a self-protection role for the concrete structure is the main problem we are concerned about. In recent years, the successive emergence of a series of smart concretes such as damage self-diagnosing concrete, temperature self-regulating concrete, and bionic self-healing concrete has laid a solid foundation for the research and development of intelligent concrete. Among them, when repairing concrete structures, usually, the material can be directly laid flat on the damaged surface by an output device.

[0003] However, in actual use, there are still some disadvantages. For example, when locally repairing a concrete structure, after the material is laid, there are usually problems such as a height difference between the material and the surface of the original concrete structure, and the overflow of too much repair material. As a result, after the repair material dries and stabilizes, the gap between the repair surface and the surface of the original concrete structure is too large, which affects its aesthetics and also brings obstacles to other construction processes on the surface of the subsequent concrete structure. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present utility model provides a flattening mechanism for local repair materials of concrete structures. By setting a push plate, a scraping plate, needle-shaped columns and rollers, and using their mutual cooperation, first align the pointed part of the push plate with one side of the repair material. At this time, push the entire fixed substrate towards one side of the repair material through the rollers at the bottom end. The multiple needle-shaped columns arranged on the outer side of the push plate surface first come into contact with the inside of the repair material, insert into the inside of the repair material, break its overall stress while dispersing the air bubbles existing inside the repair material. At the same time, the clamping head position of the push plate first comes into contact with and presses the surface of the repair material, and pushes the repair material higher than the original concrete structure towards the inclined surfaces on both sides of itself, thereby removing the excess repair material at the repair position. Then, the two sides of the scraping plate gradually come into contact with the surface of the repair material from both sides to the middle position, and perform secondary scraping and leveling on its surface to further ensure the flatness of the outer surface of the repair material. Subsequently, after the surface of the repair material is scraped and leveled for the second time, the rollers at the bottom end of the fixed substrate compact the surface of the repair material and perform the final flat compaction process, so as to ensure that the repair surface is flush with the surface of the original concrete structure, increasing its aesthetics and solving the problems proposed in the background technology.

[0005] To achieve the above objectives, the present utility model is realized through the following technical solutions: A flattening mechanism for local repair materials of concrete structures, including a fixed substrate.

First embedding slots and second embedding slots are oppositely provided at the bottom end of the fixed substrate. A push plate and a scraping plate are respectively embedded and installed inside the first embedding slot and the second embedding slot. A plurality of needle-shaped columns are sequentially and equidistantly installed on the outer side of the push plate;

[0006] The bottom ends of the scraping plate, the push plate and the roller are on the same horizontal plane, and the overall shapes of the scraping plate and the push plate are both V-shaped. The concave parts of the scraping plate and the push plate are mirror-symmetrically distributed. The widths of both sides of the scraping plate are greater than the widths of both sides of the push plate;

[0007] The needle-shaped columns are arranged parallel to the fixed substrate, and an inclined included angle is provided between the needle-shaped columns and the surface of the push plate.

[0008] Preferably, an inclined surface side block is fixedly installed on the outer side surface of the push plate. The cross-section of the inclined surface side block is triangular, and the outer side of the inclined surface side block is designed in an involute shape from top to bottom.

[0009] Preferably, the surface of the inclined side block is provided with an adaptor hole adapted to the needle-shaped column, and the outer surface of the inclined side block is smooth.

[0011] Preferably, the overall shape of the inclined side block is adapted to the outer contour shape of the push plate, and the overall material of the inclined side block is an alloy material.

[0012] Preferably, the surface of the handle is fixedly sleeved with a rubber sleeve, and the handle is designed to be parallel to the fixed substrate as a whole.

[0014] The utility model provides a flattening mechanism for local repair materials of a concrete structure. Compared with the prior art, the following advantageous effects are achieved:

[0015] 1. For the flattening mechanism for local repair materials of the concrete structure, by setting the push plate, the scraper, the needle-shaped column and the roller, and using the mutual cooperation of these components, first align the pointed part of the push plate with one side of the repair material.

The multiple needle-shaped columns arranged on the outer side of the push plate surface first come into contact with the inside of the repair material, insert into the inside of the repair material, break its overall stress while dispersing the air bubbles existing inside the repair material. At the same time, the clamping head position of the push plate first contacts and presses the surface of the repair material, and pushes the repair material with a height higher than the original concrete structure towards the inclined surface directions on both sides of itself, so as to remove the excess repair material at the repair position. Then, the two sides of the scraper gradually come into contact with the surface of the repair material towards the middle position, and perform secondary scraping and leveling on its surface to further ensure the flatness of the outer surface of the repair material. Subsequently, after the surface of the repair material is secondarily scraped and leveled, the roller at the bottom end of the fixed substrate compacts the surface of the repair material and performs final flat compaction, so as to ensure that the repair surface is flush with the surface of the original concrete structure and increase its aesthetics.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , a flattening mechanism for a local repair material of a concrete structure, including a fixed substrate 1. A handle 2 is inlaid and installed at the top end of the fixed substrate 1. Chamfers 3 are opened at the four corners of the fixed substrate 1. Support side plates 4 are symmetrically opened at the bottom end surface of the fixed substrate 1. A roller 5 is rotatably sleeved on one side of the support side plate 4. A fixed shaft hole 6 is opened on the side surface of the support side plate 4. A fixed rotating shaft 7 is inlaid and connected inside the roller 5. A first embedding groove opening 8 and a second embedding groove opening 9 are oppositely opened at the bottom end of the fixed substrate 1. A push plate 10 and a scraper 11 are respectively embedded and installed inside the first embedding groove opening 8 and the second embedding groove opening 9. A plurality of needle-shaped columns 12 are sequentially and equidistantly installed on the outer side of the push plate 10;

[0023] The bottom ends of the scraper 11, the push plate 10 and the roller 5 are on the same horizontal plane. The overall shapes of the scraper 11 and the push plate 10 are both V-shaped. The concave parts of the scraper 11 and the push plate 10 are mirror-symmetrically distributed. The widths of both sides of the scraper 11 are greater than the widths of both sides of the push plate 10;

[0024] The needle-shaped columns 12 are arranged parallel to the fixed substrate 1, and the needle-shaped columns 12 are arranged at an inclined angle with the surface of the push plate 10.

[0025] An adaptation hole 14 adapted to the needle-shaped column 12 is opened on the surface of the inclined side block 13, and the outer surface of the inclined side block 13 is smooth. The bottom end of the inclined side block 13 is on the same horizontal plane as the bottom end surface of the push plate 10. The overall shape of the inclined side block 13 is adapted to the external contour shape of the push plate 10. The overall material of the inclined side block 13 is an alloy material. There is a distance between the push plate 10 and the scraper 11, and the outer surfaces of the push plate 10 and the scraper 11 are both smooth.

[0026] The surface of the grip 2 is fixedly sleeved with a rubber sleeve, and the grip 2 as a whole is designed parallel to the fixed substrate 1.

[0027] Please refer to Figures 1-2 , an inclined side block 13 is fixedly installed on the outer side of the push plate 10. The cross-section of the inclined side block 13 is triangular, and the outer side of the inclined side block 13 is designed in an involute shape from top to bottom in sequence.

[0028] In the specific implementation manner, since the outer side of the inclined side block 13 is arranged in an involute shape from top to bottom in sequence, when the push plate 10 contacts the surface of the repair material and pushes away the excess material, the material will fall from the surface of the push plate 10 under the restriction of the inclined side surface of the inclined side block 13, so that the repair material is not easily adhered to the surface of the push plate 10, further improving the cleaning degree of the push plate 10 during operation.

[0029] Working principle

[0030] The first step: First, the operator normally assembles each component of the device, and then normally uses the device.

[0031] The second step: First, the operator holds the grip 2 on the fixed substrate 1 and aligns the pointed part of the push plate 10 with one side of the repair material. At this time, the whole fixed substrate 1 is pushed towards the side of the repair material through the roller 5 at the bottom. The multiple needle-shaped columns 12 arranged on the outer side of the surface of the push plate 10 first come into contact with the inside of the repair material and are inserted into the inside of the repair material. While breaking the overall stress thereof, the air bubbles existing inside the repair material are punctured and dispersed. At the same time, the chuck position of the push plate 10 first contacts and presses the surface of the repair material, and pushes the repair material with a height higher than the original concrete structure towards the inclined surfaces on both sides of itself, so as to remove the excess repair material at the repair position. Immediately afterwards, the two sides of the scraping plate 11 gradually come into contact with the surface of the repair material from both sides to the middle position, and perform secondary scraping and leveling on its surface, further ensuring the flatness of the outer surface of the repair material. Then, after the surface of the repair material is secondarily scraped and leveled, the roller 5 at the bottom of the fixed substrate 1 compacts the surface of the repair material and performs final flat pressing. Finally, the device completes the trimming operation on the surface of the repair material, and that's it.

[0032] The third step: First, the operator normally shuts down the device, then the operator checks whether the fixation between each component of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
