[0030] It is important to understand that sealing the holes left by the last use of bamboo and wood formwork is essential to ensure the structural integrity of the formwork when it is reused, prevent concrete leakage, and improve the durability and service life of the formwork. In addition, effective hole sealing can also help maintain construction quality, prevent air bubbles and moisture penetration, and reduce waste of building materials, which is in line with the principle of sustainable development. By increasing the reuse rate of bamboo and wood formwork, construction costs can be significantly reduced and economic benefits can be improved. It is an important resource-saving and environmental protection measure in the construction industry.

[0031] like Figures 1 to 4 As shown, according to the implementation mode of the utility model, a repair device for holes in bamboo and wood templates is proposed, the repair device comprises a slotting portion 10 and a sealing portion 20, the slotting portion 10 comprises a guide column 11, a tool 12 and a limiter 13, along the axial direction of the guide column 11, the guide column 11 is sequentially connected with the tool 12 and the limiter 13, the outer peripheral surface of the guide column 11 is used to fit with the inner surface of the hole to be repaired, along the radial direction of the guide column 11, the tool 12 protrudes from the outer peripheral surface of the guide column 11, the tool 12 is used to coaxially open an annular limit groove at one end of the hole to be repaired, the limiter 13 protrudes from the edge of the tool 12 and is used to abut against the area of ​​the bamboo and wood template located outside the hole to be repaired. The sealing portion 20 includes a limiting column 21 and a fastener 22. Along the axial direction of the limiting column 21, a sealing structure 211 is provided at one end of the limiting column 21, and the other end of the limiting column 21 is connected to the fastener 22. The outer peripheral surface of the limiting column 21 is used to abut against the inner surface to be repaired. Along the radial direction of the limiting column 21, the sealing structure 211 protrudes from the outer peripheral surface of the limiting column 21. The sealing structure 211 is used to seal the limiting groove, and the fastener 22 is connected to the limiting column 21 in a detachable manner.

[0032] According to the hole repair device of the utility model, the hole repair device realizes accurate positioning and processing of the hole to be repaired through the slotted portion 10 including a guide column 11, a tool 12 and a limiter 13. The guide column 11 enables the hole repair device to fit tightly with the inner surface of the hole to be repaired, ensuring the stability and accuracy of the repair process. The limiter groove is opened at one end of the hole by the tool 12, which further provides a reliable support for the fixation of the blocking portion 20, thereby improving the sealing and stability of the hole after repair. The blocking portion 20 realizes effective blocking of the opened limiter groove through the coordinated work of the limiter column 21 and its blocking structure 211 and the fastener 22. The blocking structure 211 enables it to accurately fill and block the limiter groove, and the detachable connection of the fastener 22 provides a convenient method to fix and adjust the position of the blocking portion 20, ensuring the compactness and reliability of the blocking. The limiter 13 protrudes from the edge of the tool 12. Such a structural arrangement ensures that the tool 12 can effectively open the limiter groove, and provides precise control of the device's penetration into the hole through the limiter 13, thereby avoiding excessive processing or damage to the hole and ensuring the accuracy and safety of the repair work. The hole repair device of the utility model realizes the rapid, accurate and reliable repair of holes in bamboo and wood formwork. The device not only improves the work efficiency of hole repair and reduces the errors that may occur during the repair process, but also improves the reuse rate and durability of bamboo and wood formwork through effective blocking, which helps to reduce the waste of building materials and meets the requirements of environmental protection and sustainable development.

[0033] The method of using the utility model is as follows: first, ensure that the surface of the bamboo and wood template to be repaired is clean and free of debris. Check whether the various components of the repair device, especially the slotted portion 10 (guide column 11, tool 12 and limiter 13) and the blocking portion 20 (limiting column 21, blocking structure 211 and fastener 22) are intact, and ensure that all components can work normally. Align the slotted portion 10 of the repair device with the hole to be repaired. Use the guide column 11 to stably position the device at the center of the hole. Start the device, rotate the tool 12 and advance it forward along the axis direction of the guide column 11, and the tool 12 will cut a limit groove at one end of the hole. The depth of this limit groove is determined by the distance between the tool 12 and the outer peripheral surface of the guide column 11. Insert the limit column 21 of the blocking portion 20 into the hole with the limit groove opened along the axis direction. Ensure that the outer peripheral surface of the limit column 21 is tightly fitted with the inner surface of the hole. Align and insert the blocking structure 211 into the limiting groove, using the limiting groove cut by the tool 12 as a guide and fixing point. Fasten the limiting column 21 to the blocking structure 211 with fasteners 22 (such as bolts or nuts). The installation of the fasteners 22 ensures that the blocking structure 211 will not loosen or fall off during use. Check whether the blocking structure 211 is fully docked with the limiting groove to ensure that the blocking effect is good and there is no gap. After the repair work is completed, conduct a careful inspection to ensure that all blocking parts 20 are correctly installed and tightened. Clean the work area and remove any residual materials or tools.

[0034] It is understandable that the guide column 11, the cutter 12 and the limiter 13 can be an integrated structure. In addition, the limiter column 21, the blocking structure 211 and the fastener 22 can also be an integrated structure.

[0035] In some embodiments, the cutter 12 is annular and designed to cut around the inner surface of the hole. This design can ensure that a stopper groove is evenly cut around the entire hole, thereby providing a uniform contact surface and fixing point for the blocking structure 211 of the blocking portion 20.

[0036] Furthermore, the annular cutter 12 has a body protruding radially outward from the guide column 11, and the end of the body facing away from the stopper 13 is a bevel 121, and the cross-sectional area of ​​the bevel 121 gradually increases along the direction from the guide column 11 to the stopper 13. The end of the annular cutter 12 connected to the guide column 11 is designed as a bevel 121. This bevel 121 design helps the cutter 12 to cut the material more easily when entering the hole, especially when encountering hard or uneven materials, the bevel 121 can disperse the cutting force and reduce damage to the material. The design of the cross-sectional area of ​​the bevel 121 gradually increasing along the direction from the guide column 11 to the stopper 13 can gradually increase the cutting depth during the cutting process, making the cutting more stable, and also convenient for the operator to control the progress and depth of the cutting process.

[0037] Furthermore, the limiter 13 is a circular limiter plate, and the outer diameter of the cutter 12 is smaller than the diameter of the limiter 13. The limiter plate is circular, and its main function is to prevent the cutter 12 from going too deep and to provide stable support during the cutting process. Since the diameter of the limiter plate is larger than the outer diameter of the cutter 12, this design helps to protect the surrounding template materials from being cut incorrectly, thereby increasing the safety of the cutting operation. The limiter plate should be disposed at the rear end of the cutter 12 and fixed on the same axis as the cutter 12. This configuration can ensure that when the cutting depth reaches the set limit, the limiter plate will promptly stop the cutter 12 from moving further forward, thereby preventing unnecessary damage to the bamboo and wood template.

[0038] It is understood that the cutter 12, the guide post 11 and the stopper 13 are connected in an assembleable manner. The stopper 13 is provided with a connecting rod 14 at its axial position. In addition, the connecting rod 14 is coaxially arranged with the guide post 11. This provides a central support point so that the cutter 12 and the stopper 13 can be precisely aligned along the center line of the guide post 11. This alignment is the key to achieving precise cutting.

[0039] Specifically, the stopper 13 can be connected to the connecting rod 14 by a threaded connection or a quick-release connection structure. This makes it simple and convenient to adjust the position of the stopper 13 to adapt to holes of different depths. The position adjustment of the stopper 13 is achieved by rotating or sliding along the connecting rod 14, and is provided with scales or marks so that the operator can accurately control and repeatedly set the position of the stopper 13.

[0040] It is understandable that one end of the connecting rod 14 is connected to the stopper 13, and the other end of the connecting rod 14 protrudes from the side of the stopper 13 away from the tool 12. The other end of the connecting rod 14 is used to connect the motor to drive the tool 12 to rotate. One end of the connecting rod 14 is fixedly connected to the stopper 13, and the other end protrudes from the side of the stopper 13 away from the tool 12. The protruding part of this end is designed to be connected to the interface of the motor, so that the motor can directly drive the connecting rod 14, and then drive the tool 12 to rotate. The connection interface between the connecting rod 14 and the motor can be a standard mechanical interface, such as a keyway, a pin or a threaded connection, to ensure the firmness of the connection and the efficiency of transmitting torque.

[0041] In some embodiments, a conical structure is provided at one end of the guide post 11 away from the cutter 12, and the bottom surface of the conical structure 111 is connected to the guide post 11, and the conical structure 111 is coaxially arranged with the guide post 11. The bottom surface of the conical structure 111 is connected to the guide post 11, and the top surface faces the open end of the guide post 11. This conical design helps to center and guide the device into the hole to be repaired, especially when the edge of the hole is irregular or partially damaged. The conical structure 111 is coaxially arranged with the guide post 11, which ensures the alignment and stability of the entire device during operation and reduces the cutting error caused by the offset of the slotting portion 10.

[0042] It is understandable that the surface of the conical structure 111 may be plated or coated to improve its corrosion resistance and reduce friction, thereby protecting the guide column 11 and extending its service life.

[0043] In some embodiments, the outer circumference of the limiting column 21 is provided with a thread, and the fastener 22 is a nut, and the nut is screwed to the limiting column 21 through the thread. The thread can be a self-locking thread or use an additional locking mechanism such as a spring washer or a stop washer to prevent the nut from automatically loosening in a vibrating environment. The nut is used as a fastener 22 and is screwed to the limiting column 21 through a thread, making the installation and fixation of the blocking part 20 simpler and faster. The user can adjust the nut manually or with a tool to change the compression force of the blocking structure 211 in the hole, thereby achieving the best blocking effect.

[0044] It is understandable that the nut material should be considered for its corrosion resistance and strength to ensure that it can maintain performance in a variety of environments, such as using hard plastic.

[0045] In some embodiments, an annular groove is provided on the outer circumference of the blocking structure 211, and an annular sealing rubber ring is accommodated in the annular groove, which is used to abut against the limiting groove. An annular groove is designed on the outer circumference of the blocking structure 211, and this groove is used to accurately accommodate the annular sealing rubber ring. The size and shape of the annular groove must accurately match the size of the rubber ring to ensure that the sealing ring can be firmly fixed in its position and will not shift or fall off during operation. The depth and width of the annular groove should be sufficient to ensure that once the rubber ring is installed, its outer surface bulges slightly above the outer surface of the blocking structure 211 so as to make effective sealing contact with the limiting groove. When the blocking structure 211 is installed in the hole and contacts the limiting groove, the annular sealing rubber ring will be slightly compressed to form a continuous, leak-proof sealing layer to prevent moisture, dust or other foreign matter from entering the hole.

[0046] Specifically, the rubber material used for the annular sealing rubber ring should have good elasticity and durability, be able to maintain its sealing performance during long-term use, and have high resistance to temperature and chemicals to ensure that it can maintain its function in various environments. The design of the sealing rubber ring should also take into account its ability to resist compression deformation, so that it will not be easily flattened even under high pressure, and maintain good recovery performance to maintain a long-lasting seal. The material of the annular sealing rubber ring can be styrene-butadiene rubber, silicone rubber or natural rubber. In order to increase the sealing effect, special additives such as anti-aging agents and reinforcing agents can be added to the material of the rubber ring to improve its performance under extreme conditions.

[0047] It is understandable that the slotting portion 10 is a high-speed steel slotting portion 10 or a cemented carbide slotting portion 10. Among them, high-speed steel is a tool steel with good wear resistance and heat resistance, which is suitable for cutting, drilling and slotting operations at higher operating speeds. Compared with other hard materials, high-speed steel has better toughness while maintaining hardness, which makes it more reliable when processing harder materials or materials with a risk of fracture. The manufacturing cost of high-speed steel is relatively low, which is suitable for large-scale production and provides a cost-effective solution. Cemented carbide is made of tungsten carbide and cobalt powder through a sintering process. It has extremely high hardness and can provide a longer service life, especially when processing very hard materials. The performance of cemented carbide at high temperatures far exceeds that of high-speed steel, which makes it more stable in high-speed cutting and drilling operations. Due to the strong deformation resistance of cemented carbide, it can maintain higher dimensional accuracy and surface finish in precision machining.

[0048] It is understandable that the plugging portion 20 is a plastic plugging portion 20. Plastic materials are generally cheaper than metals, which makes the overall production cost of using the plastic plugging portion 20 lower, thereby being price competitive in the market. Compared with metals, plastics are lighter in weight, which makes the entire device easier to carry and operate, reducing the labor intensity during use. The processing of plastics is generally simpler than that of metals, and can be quickly formed by processes such as injection molding and extrusion, which can efficiently produce parts of complex shapes. Many plastics have good chemical stability and corrosion resistance and are suitable for a variety of environmental conditions, especially in humid or chemical-rich environments. Plastics are good insulators of electricity and heat, which provides safety protection for certain specific use environments. In construction or decoration, when plugging holes to prevent leakage and enhance structural integrity, the use of a plastic plugging portion 20 can effectively block moisture and pollutants. In applications with high requirements for the environment and appearance, the diverse colors and smooth surfaces of plastics can provide beautiful visual effects and adaptability.

[0049] Specifically, PVC (polyvinyl chloride) is selected as the material of the plugging part 20. PVC has good resistance to a variety of chemicals, including a variety of acids and alkalis, which makes it very practical in the chemical or construction industry. PVC is very suitable for use in water and humid environments because it does not absorb water or be affected by humid environments, ensuring a long-term plugging effect. PVC material has good durability and a long service life, can resist daily wear and tear, and reduces maintenance requirements. PVC is an economical and efficient material choice, it is relatively low in cost and easy to mass produce. PVC can be easily processed into complex shapes by injection molding, extrusion and other methods, which is particularly important for the production of specifically designed plugging parts 20. In the construction industry, the PVC plugging part 20 can be used to repair and plug holes, such as cable channels, water pipe penetrations, etc., to ensure the integrity and waterproof performance of the structure. When repairing holes in bamboo and wood formwork, the PVC plugging part 20 can effectively prevent moisture and impurities from entering, improving the reuse performance and quality of the formwork.

[0050] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
