Description

Technical Field

[0001] This utility model relates to the field of concrete reinforcement technology, specifically to a reinforcement device. Background Technology

[0002] Concrete is an engineering composite material made by mixing cementitious materials, aggregates, water, and admixtures, if necessary, in a certain proportion. Because concrete structures may develop cracks, deformations, or structural failures under long-term use or external forces, it is necessary to strengthen and reinforce existing concrete structures to improve their load-bearing capacity, seismic performance, and durability, thereby ensuring the stability and safety of concrete buildings.

[0003] A search revealed an existing patent (publication number: CN213927616U) that discloses a reinforcement and repair device for concrete structures. The device includes a template covering a damaged groove in the concrete structure. Several reinforcement sleeves are located on the lower side of the template and extend into the damaged groove. A recessed head is fixedly connected to the lower end of each reinforcement sleeve and is embedded in the bottom of the damaged groove. The recessed head is an inverted conical structure with a top diameter larger than the diameter of the reinforcement sleeve. A guide cavity extending into the recessed head is provided inside the reinforcement sleeve. Several guide holes communicating with the guide cavity are provided on the outer walls of both the reinforcement sleeve and the recessed head. A guide pipe is detachably connected to the upper end of the reinforcement sleeve and penetrates the template. This invention is used to repair damaged areas of concrete structures and makes it difficult for newly filled concrete to separate from the old concrete after repair.

[0004] However, in the above scheme, because the position of the grout outlet is fixed, when the damaged groove is small and the grout outlet is located outside the damaged groove, the staff cannot know in time whether the inside of the damaged groove is filled with concrete, which is not conducive to the repair and reinforcement of the damaged groove.

[0005] In view of this, the present invention proposes a reinforcement device. Utility Model Content

[0006] This utility model proposes a reinforcement device that solves the problem in related technologies where the outlet position is fixed, making it inconvenient to apply to damaged grooves of different sizes.

[0007] The technical solution of this utility model is as follows: A reinforcement device includes a concrete structure; a top cover movably connected to the top of the concrete structure, with a grouting port movably connected to the middle position of the top of the top cover, and a grout outlet on one side of the top of the top cover; an anti-overflow component mounted on the grout outlet, the anti-overflow component being used for elastic sealing of the inside of the grout outlet; a connecting groove opened on one side of the bottom end of the top cover, the top side of the connecting groove communicating with the bottom end of the grout outlet, and a sliding groove penetrating the top cover being opened on one side of the connecting groove; a sealing plate movably connected to the lower end of one side of the top cover, and a sliding plate extending into the connecting groove being fixedly connected to one side of the sealing plate; an installation component mounted on one side of the top cover, the installation component being used to realize quick assembly and disassembly between the top cover and the sealing plate; a reinforcement pipe movably disposed at the bottom end of the top cover, with a recessed head disposed below the reinforcement pipe; and a telescopic component mounted at the bottom end of the reinforcement pipe, the telescopic component being used to realize telescopic sliding between the recessed head and the reinforcement pipe.

[0008] The mounting assembly includes: a mounting groove formed at the lower end of one side of the top cover; a slide rod fixedly connected to the inner wall of the mounting groove, a sliding plate slidably connected to the surface of the slide rod, a mounting spring wound around the surface of the slide rod, and the two ends of the mounting spring being fixedly connected to the top wall of the mounting groove and the bottom end of the sliding plate, respectively; a mounting block fixedly connected to one side of the bottom end of the sliding plate; and a mounting hole formed at the top of the sealing plate.

[0009] Preferably, the bottom end of the mounting block and the interior of the mounting hole form an engaging structure, and the top end of the mounting block and one side of the bottom end of the sliding plate form a welded integral structure.

[0010] Preferably, the inner top wall of the slide groove is provided with a slot, and a card plate is fixedly connected to one side of the top of the sliding plate to slide and engage with the inside of the slot. The card plate and the slot are inverted convex in shape.

[0011] Preferably, the area of ​​the cross-section of the sealing plate is larger than the area of ​​the cross-section of one side of the slide groove and the slot, and a tie rod is fixedly connected to the other side of the sealing plate.

[0012] Preferably, the telescopic assembly includes: a telescopic groove formed inside the reinforcing pipe; a telescopic spring fixedly connected to the top wall of the telescopic groove; a sliding block fixedly connected to the bottom end of the telescopic spring, the bottom end of the sliding block extending to the outside of the telescopic groove, and the bottom end of the telescopic rod being fixedly connected to the top end of the countersunk head.

[0013] Preferably, the sliding block and the interior of the telescopic groove form a sliding structure, and the telescopic groove and the sliding block are cross-shaped.

[0014] Preferably, the surface of the reinforcing tube is fixedly connected with pull-out blocks at equal angles and intervals, and the pull-out blocks are tilted at an angle of 15 degrees to the horizontal direction.

[0015] Preferably, the countersunk head is conical in shape, and the top end of the countersunk head and the bottom end of the telescopic rod are welded together as an integral structure.

[0016] Preferably, the anti-overflow assembly includes: a fixing groove equally spaced at the top of the top cover; a sliding rod movably connected inside the fixing groove; a fixing spring wound around the surface of the sliding rod, with both ends of the fixing spring fixedly connected to the top wall of the fixing groove and the lower end of the sliding rod, respectively; and an anti-overflow cover fixedly connected to the top of the three sliding rods.

[0017] Preferably, the lower end of the sliding rod forms a sliding structure with the interior of the fixed groove, and the shape of the sliding rod is an inverted T-shape.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this invention, the connecting groove is relatively long, so even if the damaged groove is small, one end of the connecting groove can still be inside the groove, preventing excess grout from being discharged through the grout outlet in time due to the small groove. At the same time, the anti-overflow component can be used to seal the top of the grout outlet when the grout is not full, so that the grout can overflow through the grout outlet only after the grout is full. After the repair and reinforcement are completed, the sealing plate can be easily disassembled using the installation component, and then the sliding plate can be slidably disassembled to facilitate the removal of excess concrete grout inside the connecting groove, preventing it from accumulating too much and affecting the subsequent repair and reinforcement work.

[0020] In this invention, after the top cover is tightly closed to the concrete structure, the reinforcing pipe and the countersunk head will move relative to each other. This causes the telescopic rod to drive the sliding block to slide and compress the telescopic spring inside the telescopic groove. As a result, reinforcing pipes and countersunk heads of the same specification and length can be used in grooves of different depths. This avoids the irregular bottom wall of the groove, which would make it difficult for some countersunk heads to be firmly tightened inside the concrete structure. This allows multiple reinforcing pipes and countersunk heads to be installed more closely inside the damaged grooves on the concrete structure, facilitating the repair work of the grooves and improving the tightness and firmness of the connection between the old and new concrete.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0030] A preferred embodiment of the reinforcement device provided by this utility model is, for example... Figures 1 to 6The following is a description of a reinforcement device: A concrete structure 2; a top cover 1 movably connected to the top of the concrete structure 2, with a grouting port 3 movably connected to the middle of the top of the top cover 1, and a grout outlet 13 opened on one side of the top of the top cover 1; an anti-overflow component 4 assembled on the grout outlet 13, the anti-overflow component 4 being used for elastic sealing of the inside of the grout outlet 13; a connecting groove 9 opened on one side of the bottom end of the top cover 1, the top of the connecting groove 9 communicating with the bottom end of the grout outlet 13, and a through-hole opening on one side of the connecting groove 9 penetrating the top cover 1. A sliding groove 16; a sealing plate 11 movably connected to the lower end of one side of the top cover 1, and a sliding plate 8 extending into the communicating groove 9 is fixedly connected to one side of the sealing plate 11; an installation assembly 5 assembled on one side of the top cover 1, which is used to realize quick assembly and disassembly between the top cover 1 and the sealing plate 11; a reinforcing tube 7 movably set at the bottom end of the top cover 1, and a countersunk head 15 is provided below the reinforcing tube 7; and a telescopic assembly 6 assembled at the bottom end of the reinforcing tube 7, which is used to realize telescopic sliding between the countersunk head 15 and the reinforcing tube 7.

[0031] The mounting assembly 5 includes: a mounting groove 501 formed at the lower end of one side of the top cover 1; a slide rod 506 fixedly connected to the inner wall of the mounting groove 501, a sliding plate 504 slidably connected to the surface of the slide rod 506, a mounting spring 505 wound around the surface of the slide rod 506, and the two ends of the mounting spring 505 being fixedly connected to the inner top wall of the mounting groove 501 and the bottom end of the sliding plate 504 respectively; a mounting block 503 fixedly connected to one side of the bottom end of the sliding plate 504; and a mounting hole 502 formed at the top of the sealing plate 11.

[0032] In this embodiment, by moving the sliding plate 504 and causing the mounting block 503 to slide up until it is completely disengaged from the inside of the mounting hole 502, the pull rod 12 is pulled to move the sealing plate 11 to slide out, so as to facilitate the cleaning of the residual concrete slurry inside the connecting groove 9.

[0033] In a further preferred embodiment of the present invention, the bottom end of the mounting block 503 and the interior of the mounting hole 502 form an engaging structure, and the top end of the mounting block 503 and one side of the bottom end of the sliding plate 504 form a welded integrated structure.

[0034] In this embodiment, the engagement between the mounting block 503 and the mounting hole 502 improves the firmness and stability of the engagement between the sealing plate 11 and the top cover 1.

[0035] In a further preferred embodiment of the present invention, a slot 17 is provided on the inner top wall of the slide groove 16, and a card plate 10 is fixedly connected to one side of the top of the sliding plate 8 and slides and engages with the inside of the slot 17. The card plate 10 and the slot 17 are inverted convex in shape.

[0036] In this embodiment, the sliding engagement between the inverted convex plate 10 and the slot 17 allows the sliding plate 8 to slide only back and forth, thereby improving the stability of the sliding installation of the sliding plate 8.

[0037] In a further preferred embodiment of the present invention, the area of ​​the cross-section of the sealing plate 11 is greater than the area of ​​the cross-section of one side of the slide groove 16 and the slot 17, and a pull rod 12 is fixedly connected to the other side of the sealing plate 11.

[0038] In this embodiment, the pull rod 12 is used to facilitate the sliding and disassembly of the sealing plate 11 by the staff. Example

[0039] Based on Embodiment 1, a preferred embodiment of the reinforcement device provided by this utility model is, for example... Figures 1 to 6 As shown: The telescopic assembly 6 includes: a telescopic groove 601 formed inside the reinforcing pipe 7; a telescopic spring 602 fixedly connected to the top wall of the telescopic groove 601; a sliding block 603 fixedly connected to the bottom end of the telescopic spring 602; a telescopic rod 604 extending from the bottom end of the sliding block 603 to the outside of the telescopic groove 601; and a fixed connection between the bottom end of the telescopic rod 604 and the top end of the countersunk head 15.

[0040] In this embodiment, after the top cover 1 is tightly closed to the concrete structure 2, the reinforcing pipe 7 and the countersunk head 15 will move relative to each other, causing the telescopic rod 604 to drive the sliding block 603 to slide and compress the telescopic spring 602 inside the telescopic groove 601. This allows the reinforcing pipe 7 and the countersunk head 15 of the same specification and length to be used in grooves of different depths, avoiding the irregular bottom wall of the groove from causing some countersunk heads 15 to be difficult to firmly tighten inside the concrete structure 2.

[0041] In a further preferred embodiment of the present invention, a sliding structure is formed between the sliding block 603 and the interior of the telescopic groove 601, and the telescopic groove 601 and the sliding block 603 are cross-shaped.

[0042] In this embodiment, the sliding of the cross-shaped sliding block 603 and the inside of the telescopic groove 601 is used to improve the smoothness of the sliding of the telescopic rod 604 and the countersunk head 15.

[0043] In a further preferred embodiment of this utility model, the surface of the reinforcing tube 7 is fixedly connected with anti-pull-out blocks 14 at equal angles and intervals, and the anti-pull-out blocks 14 are tilted at an angle of fifteen degrees to the horizontal direction.

[0044] In this embodiment, the inclined anti-pull-out block 14 is used to increase the connection area between the reinforcing pipe 7 and the concrete, thereby improving the tightness of the connection between the newly injected concrete and the reinforcing pipe 7.

[0045] In a further preferred embodiment of this utility model, the countersunk head 15 is conical in shape, and the top end of the countersunk head 15 and the bottom end of the telescopic rod 604 are welded together as an integrated structure.

[0046] In this embodiment, a conical countersunk head 15 is used to facilitate its tightening into the bottom wall of the damaged groove.

[0047] In a further preferred embodiment of the present invention, the anti-overflow component 4 includes: a fixing groove 402 formed at an equal angle at the top of the top cover 1; a sliding rod 404 movably connected inside the fixing groove 402; a fixing spring 403 wrapped around the surface of the sliding rod 404, with both ends of the fixing spring 403 fixedly connected to the top wall of the fixing groove 402 and the lower end of the sliding rod 404 respectively; and an anti-overflow cover 401 fixedly connected to the top of the three sliding rods 404.

[0048] In this embodiment, the elastic force of the fixed spring 403 is used to make the overflow cover 401 fit tightly against the top of the slurry outlet 13, thereby sealing it and making it difficult for the slurry inside the groove to be discharged from the slurry outlet 13. After the groove is filled with slurry, the pressure of the excess slurry will cause the overflow cover 401 to rise, driving the sliding rod 404 to slide up and compress the fixed spring 403, and then be discharged from the gap between the bottom end of the overflow cover 401 and the top end of the top cover 1.

[0049] In a further preferred embodiment of the present invention, a sliding structure is formed between the lower end of the sliding rod 404 and the interior of the fixing groove 402, and the shape of the sliding rod 404 is an inverted T-shape.

[0050] In this embodiment, the sliding of the inverted T-shaped sliding rod 404 inside the fixing groove 402 is used to improve the stability of the up-and-down sliding of the overflow cover 401.

[0051] The working principle of this utility model is as follows: First, select and install different numbers of reinforcing pipes 7 and countersunk heads 15 according to the size and depth of the groove. Then, screw the countersunk heads 15 into the bottom wall of the groove in sequence. Next, cover the top cover 1 on the groove and apply pressure to the top cover 1 through external brackets, so that the top cover 1 can be tightly pressed against the concrete structure 2. At the same time, after the top cover 1 is tightly closed with the concrete structure 2, the reinforcing pipes 7 and countersunk heads 15 will move relative to each other, so that the telescopic rod 604 drives the sliding block 603 to slide and compress the telescopic spring 602 inside the telescopic groove 601. Thus, the reinforcing pipes 7 and countersunk heads 15 of the same specification and length can be used for grooves of different depths, avoiding the irregular bottom wall of the groove, which makes it difficult for some countersunk heads 15 to be firmly screwed into the concrete structure 2.

[0052] Then, during the repair, new concrete grout is injected into the groove through the grouting port 3. At this time, the elasticity of the fixed spring 403 is used to make the overflow cover 401 stick tightly to the top of the grout outlet 13, thereby sealing it and making it difficult for the grout inside the groove to be discharged from the grout outlet 13. After the groove is filled with grout, the excess grout will be transported into the grout outlet 13 through the connecting groove 9. When the pressure of the excess grout is greater than the elasticity of the fixed spring 403, the overflow cover 401 will rise and drive the sliding rod 404 to slide up and compress the fixed spring 403, and then be discharged from the gap between the bottom of the overflow cover 401 and the top of the top cover 1, so that the staff can know in time.

[0053] At the same time, the inclined anti-pull block 14 is used to increase the connection area between the reinforcing pipe 7 and the concrete, thereby improving the tightness of the connection between the newly injected concrete and the reinforcing pipe 7. Furthermore, the countersunk head 15 is tightened into the bottom wall of the groove, which can further improve the tightness and firmness of the connection between the new and old concrete.

[0054] After the concrete has solidified, the top cover 1 is removed. Then, by moving the sliding plate 504, the spring 505 is compressed on the surface of the sliding rod 506, and the mounting block 503 is moved up until it is completely disengaged from the inside of the mounting hole 502. Then, the pull rod 12 is pulled to move the sealing plate 11 to slide and the sliding plate 8 is slid out, which makes it easier to clean the residual concrete slurry inside the connecting groove 9.

[0055] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
