Description

Technical Field

[0001] This utility model relates to the field of crack repair technology, specifically a concrete crack repair structure. Background Technology

[0002] Concrete cracks are physical structural changes caused by internal and external factors in concrete structures. Cracks are the main reason for the reduction in the load-bearing capacity, durability, and waterproofing of concrete structures.

[0003] When repairing concrete cracks, the repair nozzle of the device is usually inserted into the crack and filled with repair agent. However, the repair nozzles on current repair devices are usually set too large, squeezing out a large amount of repair agent each time to repair the crack. However, this type of repair device is usually only suitable for larger cracks. If it is used to repair smaller cracks, the repair nozzle is difficult to insert into the crack, and a large amount of repair agent will be squeezed to both sides of the crack, resulting in waste of repair agent.

[0004] Therefore, we propose a concrete crack repair structure to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a concrete crack repair structure, including a repair cylinder, wherein a placement groove is provided on the repair cylinder for storing a repair agent bottle; a drive chamber located within the placement groove is also provided inside the repair cylinder, and a drive structure is installed inside the drive chamber, with the drive end of the drive structure extending through the drive chamber into the placement groove, and the drive structure is used to apply pressure to the repair agent bottle, squeezing out the repair agent in the bottle to repair the crack; a baffle located within the placement groove is fixed at the end of the repair cylinder, and the baffle is used to block the agent, and a fixed repair nozzle is provided on the baffle, which is used to repair wide cracks, and a movable repair nozzle is detachably installed on the fixed repair nozzle, which is used to repair small cracks.

[0007] Furthermore: the drive structure includes an electric telescopic rod installed in the drive chamber, a fixing member is installed at the drive end of the electric telescopic rod, a drive rod extending into the placement groove is fixed on the fixing member, a push rod is fixed at the center of the drive rod facing the baffle, and a compression plate for squeezing the repair agent bottle is fixed at one end of the push rod.

[0008] Furthermore, the drive chamber has two parallel limiting plates fixed inside, with a gap between the two limiting plates for storing the electric telescopic rod.

[0009] Furthermore: the two ends of the movable repair nozzle are a connection port and a repair port, respectively, and the diameter of the connection port is larger than the diameter of the repair port. The connection port is sealed to the fixed repair nozzle, and the repair port is used to repair small gaps.

[0010] Furthermore: the fixed repair nozzle has several limiting protrusions fixed at equal intervals along the circumferential direction, and the inner wall of the movable repair nozzle has several limiting grooves at equal intervals along the circumferential direction, and the several limiting protrusions and several limiting grooves are inserted and adapted to each other.

[0011] Furthermore: a threaded connecting sleeve is installed on the fixed repair nozzle, and an annular protrusion is fixed on the threaded connecting sleeve near the inner broken arm of the fixed repair nozzle. The annular protrusion is located on one side of a plurality of the limiting protrusions, and the threaded connecting sleeve is threadedly connected to one end of the movable repair nozzle.

[0012] The beneficial effects of this utility model are: This invention features a fixed repair nozzle fixedly mounted on one side of a baffle. A driving device can apply pressure to the repair agent bottle, causing the repair agent inside to be squeezed out through the fixed repair nozzle to repair larger cracks. This allows for the extrusion of more repair agent, improving the efficiency of crack repair. Alternatively, a movable repair nozzle can be installed on the fixed repair nozzle, allowing the movable repair device to be inserted into small cracks. The movable repair nozzle can then repair small cracks, reducing the amount of repair agent squeezed to the sides of the crack and thus minimizing waste. Attached Figure Description

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] A concrete crack repair structure includes a repair cylinder 1, which is semi-circular in shape. The upper part of the repair cylinder 1 has a semi-circular placement groove 2 along the axial direction for storing a repair agent bottle 3. The lower part of the repair cylinder 1 has a driving chamber 4 along the length direction, and a driving structure 5 is installed inside the driving chamber 4. The driving part of the driving structure 5 extends into the placement groove 2. The driving structure 5 is used to apply pressure to the repair agent bottle 3 so that the repair agent in the repair agent bottle 3 can be squeezed out and repair the concrete crack. A baffle 6 is fixed to one end of the repair cylinder 1, and the baffle 6 is fixed to one side of the placement groove 2. The baffle 2 can block the repair agent bottle 3 and prevent the repair agent bottle 3 from shaking during the squeezing process. A fixed repair nozzle 7 is provided at the center of the baffle 6. During use, the repair nozzle of the repair agent bottle 3 is correspondingly set with the fixed repair nozzle 7, so that the repair agent in the repair agent bottle 3 can pass through the fixed repair nozzle 7 to repair the wide concrete crack. A movable repair nozzle 8 is detachably installed on the fixed repair nozzle 7. Specifically, the movable repair nozzle 8 includes a connecting port 801 and a repair port 802. The repair port 801 is used to seal the connection with the fixed repair nozzle 7 to prevent the repair agent from leaking out during the repair process. The diameter of the repair port 802 is smaller than that of the fixed repair nozzle 7 and the repair port 801, so that it can repair small cracks, reduce the leakage of repair agent, and reduce the waste of repair agent.

[0017] In detail: The fixed repair nozzle 7 has several limiting protrusions 701 fixed at equal intervals along the circumference, with a certain gap between two adjacent limiting protrusions 701; the inner sidewall of the connecting port 801 has several limiting grooves 702 at equal intervals along the circumference, and the several limiting protrusions 701 and several limiting grooves 702 are inserted and adapted to each other, thereby limiting the movable repair nozzle 8 and preventing the phenomenon of tightening during the tightening of the movable repair nozzle 8, thus having strong stability.

[0018] The fixed repair nozzle 7 is fitted with a threaded connecting sleeve 9. It should be noted that: one side of the threaded connecting sleeve 9 is fixed with an annular protrusion 10, and several limiting protrusions 701 are used to limit the annular protrusion 10 to prevent the threaded connecting sleeve 9 from falling off the fixed repair nozzle 7. One end of the threaded connecting sleeve 9 passes through the fixed repair nozzle 7 and is threadedly connected to the connecting port 801, thereby securing the movable repair nozzle 8.

[0019] In detail: The drive structure 5 includes an electric telescopic rod 501 installed in the drive chamber 4. Inside the drive chamber 4, two parallel limiting plates 401 are fixed, with a certain gap between them. This gap serves to block the electric telescopic rod 501, preventing it from wobbling during use and providing strong stability. The telescopic end of the electric telescopic rod 501 passes through one of the limiting plates 401 and is fixed with a fixing member 502. A drive rod 503 is fixed on the top of the drive chamber 4, and a groove 101 communicating with the placement groove 2 is opened on the top of the drive chamber 4 along the length direction. The drive rod 503 passes through the groove 101 and a drive plate 504 is fixed thereon. A push rod 505 is fixed at the center of the drive plate 504. It should be noted that the push rod 505 is set towards the baffle 6, and a compression plate 506 is fixed at one end of the push rod 505. The compression plate 506 is used to compress the repair agent bottle 3 so that the repair agent in the repair agent bottle 3 can be squeezed out and repair the crack.

[0020] Before repairing concrete cracks: depending on the size of the crack, it may be necessary to install a movable repair nozzle on the repair device. For repairing larger concrete cracks, it is usually not necessary to install a movable repair nozzle. First, the electric telescopic rod 501 is activated. The telescopic end of the electric telescopic rod 501 can drive the fixing part 502 to move, so that the fixing part 502 pushes the extrusion plate 506 through the drive rod 503, push rod 504 and extrusion plate 505 in sequence. The extrusion plate 506 can squeeze the inside of the repair agent bottle 3, so that the repair agent in the repair agent bottle 3 can be discharged through the fixed repair nozzle 7 to repair larger concrete cracks. It can quickly repair concrete cracks and is highly efficient.

[0021] When repairing smaller concrete cracks, a movable repair nozzle 8 needs to be installed on the fixed repair nozzle 7. Then, the same operation is performed as described above, so that the repair agent in the repair agent bottle 3 passes through the fixed repair nozzle 7 and the movable repair nozzle 8 in sequence to repair the small concrete cracks. This can reduce the overflow of repair agent to both sides of the crack and reduce waste.

[0022] When installing the movable repair nozzle 8, first insert the connecting port 801 on one side of the movable repair nozzle 8 into one end of the fixed repair nozzle 7. Several limiting protrusions 701 and several limiting grooves 702 are inserted and matched to prevent the fixed repair nozzle 7 and the movable repair nozzle 8 from rotating in opposite directions during the tightening process. Then, rotate the threaded connecting sleeve 9 so that the threaded connecting sleeve 9 can tighten the movable repair nozzle 8, preventing the movable repair nozzle 8 from loosening during use and providing strong stability.
