Description

Technical Field

[0001] This invention relates to the field of bridge reinforcement, and more specifically, to a bridge structure reinforcement mold and reinforcement method. Background Technology

[0002] Bridge reinforcement generally refers to restoring or improving the load-bearing capacity of existing bridges by strengthening components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation. There are various reinforcement methods, such as strengthening weak components and adding auxiliary components.

[0003] The existing patent (publication number: CN108708302B) discloses a bridge structure reinforcement mold. By forming a ring structure with a specific circumferential size, it has good adaptability and can meet the reinforcement needs of viaduct piers with different circumferential sizes. It uses two adjacent template blocks to form an included angle, and embeds a pressing block in the included angle. The pressing block is connected to the two adjacent template blocks by bolts. It has good combinability, is easy to assemble and disassemble, and can effectively improve construction efficiency.

[0004] While the aforementioned application documents address the issue of reinforcing bridges of varying sizes by creating a ring structure with a specific circumferential dimension based on the circumferential dimensions of the piers, this approach limits its application to fixing only ring-shaped bridges and restricts its applicability. Summary of the Invention

The triangular block extends into the interior of the limiting wheel, so that the cylinder cannot rotate and the reinforcement components cannot rotate, which can achieve better support effect and can support bridge piers of different sizes and shapes, avoiding the need to make other reinforcement molds for fixing the bridge piers due to size differences.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0010] One side of the movable rod extends to form a limiting block, one side of the limiting block extends to form an extending rod, and the end of the extending rod away from the limiting block extends to form a triangular block. A third sliding groove is provided inside the movable rod.

[0011] One side of the reinforcement extends to form a first extension block, and an installation block is installed on one side of the first extension block. The installation block and the first extension block are connected by bolts. A cylinder is installed between the first extension block and the installation block. The cylinder is rotatably connected to the first extension block and the installation block. A limiting wheel is installed on the surface of the cylinder.

[0012] Furthermore, the rear end of the movable rod extends to form a third extension block, and a first sliding groove is provided inside the reinforcement corresponding to the position of the third extension block, and the third extension block is slidably connected to the inside of the first sliding groove.

[0013] Furthermore, the reinforcement member has equidistant mounting slots inside, and a limiting member is installed inside the mounting slot. The limiting member is slidably connected to the inside of the mounting slot. The limiting member has a groove inside, and the groove is on the same horizontal plane as the moving rod. Multiple sets of grooves are provided.

[0014] Furthermore, the reinforcing member extends to form a second extension block on the side near the limiting member. A second groove is provided inside the limiting member corresponding to the position of the second extension block. The second extension block is slidably connected to the inside of the second groove. A plurality of spring pieces are provided inside the second groove. The cross-sectional shape of the spring pieces is a right trapezoid, and the inclined surface of the spring pieces faces the opposite direction to the movement direction of the limiting member.

[0015] Furthermore, a support is installed at one end of the limiting member, the limiting member and the support are fixedly connected, a second circular hole is provided inside the support, and a first circular hole is provided inside the limiting member corresponding to the position of the second circular hole, the second circular hole and the first circular hole are connected.

[0016] Furthermore, support rods are connected to both sides of the support member, the support member and the support rods are rotatably connected, the end of the support rod away from the support member extends into the interior of the movable rod, and the end of the support rod is slidably connected to the movable rod.

[0017] Furthermore, a toothed plate is installed inside the movable rod, the toothed plate is slidably connected to the inside of the movable rod, the right side of the toothed plate extends to form a triangular plate, the axial cross-section of the triangular plate is a right triangle, and the inclined surface of the triangular plate is the side away from the limiting block.

[0018] Furthermore, a lead screw is installed inside the reinforcing member, and the reinforcing member and the lead screw are connected by threads. An extrusion groove is opened inside the moving rod corresponding to the position of the lead screw.

[0019] Furthermore, the cross-sectional shape of the extrusion groove is a right trapezoid, and the end of the lead screw near the extrusion groove is in contact with the inclined surface of the extrusion groove.

[0020] A bridge structure reinforcement mold, wherein the cross-sectional shape of the extrusion groove is a right trapezoid, and the end of the lead screw near the extrusion groove is in contact with the inclined surface of the extrusion groove.

[0022] S1: Concrete base treatment, grinding the protruding parts of the component surface, and using a blower to clean the surface dust and debris;

[0023] S2: Erection. By measuring the length of the reinforcement and the circumference of the pier, as well as the location of the crack in the pier, the overall length of the device is adjusted by increasing the number of reinforcements to better suit piers of different sizes and shapes.

[0026] 3. Beneficial effects

[0027] Compared with the prior art, the advantages of this invention are:

[0028] 1. This solution adjusts the number of reinforcement components by measuring the length of the bridge pier, making the device fit the bridge pier more tightly and its application range wider. The triangular block extends into the inside of the limiting wheel, so the cylinder cannot rotate and the reinforcement components cannot rotate, resulting in better support. It can also support bridge piers of different sizes and shapes, avoiding the need to make other reinforcement molds for fixing the bridge piers due to size differences.

[0029] 2. This solution uses multiple grooves to fix irregularly shaped bridge piers, making it more widely applicable. The length of the limiting component can be adjusted according to the shape of the bridge pier. The unused installation grooves can be used to observe the inside of the bridge pier, allowing staff to monitor the condition of the bridge pier in real time. This avoids the bridge collapsing due to the instability of the bridge piers because it is difficult for staff to observe the internal condition of the bridge pier after the reinforcement mold is added.

[0030] 3. This solution uses a spring clip to hold the second extension block in place, making it difficult for the limiting component to return to its original position after it has been moved to the appropriate position. This avoids the device vibrating when the vehicle moves on the bridge, causing the limiting component to move due to vibration, which would result in poor limiting effect on the bridge pier and serious damage to the bridge pier.

[0031] 4. This solution can be adjusted according to the length of the extension of the limiting component, so that some parts will not be difficult to support due to the irregular shape of the pier. This avoids the pier shifting due to poor support effect, resulting in poor support effect of the pier on the bridge and causing the bridge to collapse.

[0032] 5. In this design, the teeth on the side of the toothed plate are inserted into the interior of the second circular hole to restrict the support rod. This prevents the second circular hole from moving inside the moving rod, which would prevent the support rod from effectively supporting the restrictor and the pier. As a result, the device has a poor support effect, and the pier may tilt or even collapse due to the poor support effect. This could lead to the bridge collapsing due to lack of support, causing a major accident.

[0033] 6. This solution uses a rotating lead screw to press against the side wall of the extrusion groove, making it easier to drive the limiting block to move. This makes the movement of the moving rod more stable and effectively avoids the moving rod from shifting, which would make it difficult for the limiting block to fit into the groove and cause poor stability of the device.

[0034] 7. This solution injects epoxy resin mortar through the first circular hole, allowing it to pass through to the second circular hole. This makes it easier to inject the epoxy resin mortar into the cracks of the bridge pier, resulting in a better repair effect. The two approaches enhance the support and prevent the cracks from widening. These two effects complement each other, making the reinforcement of the bridge pier more solid and avoiding potential problems that could lead to bridge collapse. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] Example 1:

[0049] Please see Figures 1-2 and Figure 6A bridge structure reinforcement mold and reinforcement method, including a reinforcement member 1, wherein a movable rod 5 is slidably connected to the front end surface of the reinforcement member 1, the top of the movable rod 5 penetrates the top of the limiting member 2, and the movable rod 5 is slidably connected to the limiting member 2;

[0050] One side of the movable rod 5 extends to form a limiting block 51, one side of the limiting block 51 extends to form an extending rod 511, and the end of the extending rod 511 away from the limiting block 51 extends to form a triangular block 512. A third sliding groove 53 is provided inside the movable rod 5.

[0051] One side of the reinforcement 1 extends to form a first extension block 11, and a mounting block 12 is installed on one side of the first extension block 11. The mounting block 12 is connected to the first extension block 11 by bolts. A cylinder 3 is installed between the first extension block 11 and the mounting block 12. The cylinder 3 is rotatably connected to the first extension block 11 and the mounting block 12. A limiting wheel 31 is installed on the surface of the cylinder 3. The limiting wheel 31 and the triangular block 512 are on the same vertical plane. The rear end of the moving rod 5 extends to form a third extension block 52. A first sliding groove 13 is opened inside the reinforcement 1 corresponding to the position of the third extension block 52. The third extension block 52 is slidably connected to the inside of the first sliding groove 13.

[0052] The number of reinforcement components 1 is adjusted by measuring the length of the bridge pier. The mounting block 12 is removed, exposing the first extension block 11. To increase the number of reinforcement components 1, the mounting block 12 on one side of another reinforcement component 1 is placed next to the first extension block 11 on the same side of this reinforcement component 1, and secured with bolts to connect the first extension block 11 to the mounting block 12. Repeating this process allows for the addition of multiple reinforcement components 1 to change the length of the device. All reinforcement components 1 are connected by rotating cylinders 3. Because the device is a flexible structure, it fits more tightly against the bridge pier, expanding its applicability. Furthermore, the top and bottom of the multiple reinforcement components 1 provide support to the bridge. This improves the support effect. By moving the moving rod 5, the moving rod 5 moves the limiting block 51, and the moving limiting block 51 moves the extension rod 511. One side of the extension rod 511 extends to form a triangular block 512, and the triangular block 512 is on the same vertical plane as the limiting wheel 31. By moving the moving rod 5, the moving rod 5 moves the triangular block 512 into the interior of the limiting wheel 31. By restricting the limiting wheel 31, the cylinder 3 is restricted, so that the cylinder 3 cannot rotate and the multiple reinforcement parts 1 cannot rotate, thus improving the support effect. It can also support piers of different sizes and shapes, avoiding the need to make other reinforcement molds for fixing the piers due to size differences.

[0053] Please see Figure 3 ;

[0054] The reinforcement 1 has equidistant mounting slots 14 inside, and a limiting member 2 is installed inside the mounting slot 14. The limiting member 2 is slidably connected to the inside of the mounting slot 14. The limiting member 2 has a groove 24 inside, and the groove 24 is on the same horizontal plane as the moving rod 5. Multiple sets of grooves 24 are provided.

[0055] By moving the limiting member 2, one side of the limiting member 2, along with the support member 4, abuts against the side wall of the pier. This support improves the support effect. As the moving rod 5 moves downward with the limiting block 51, the limiting block 51, after moving, is inside the groove 24. The limiting block 51 restricts the groove 24, fixing the limiting member 2 in this position, making the fixing more convenient. Since the limiting member 2 is movable and there are multiple grooves 24, it can fix irregularly shaped piers, making it more widely applicable. The length of the limiting member 2 can be adjusted according to the shape of the pier without needing to insert it into the mounting slot 14 of the limiting member 2. This allows for observation of the pier's interior, enabling staff to monitor the pier's condition in real time. This avoids the bridge collapsing due to the instability of the piers, which could be caused by the difficulty in observing the internal condition of the pier after the reinforcement mold is added.

[0056] Please see Figure 4 ;

[0057] The reinforcing member 1 extends to form a second extension block 15 on the side near the limiting member 2. A second groove 21 is formed inside the limiting member 2 corresponding to the position of the second extension block 15. The second extension block 15 is slidably connected to the inside of the second groove 21. A plurality of spring pieces 22 are formed inside the second groove 21. The cross-sectional shape of the spring pieces 22 is a right trapezoid, and the inclined surface of the spring pieces 22 faces the opposite direction to the movement direction of the limiting member 2.

[0058] As the limiting member 2 moves, the second extension block 15 moves inside the second slide groove 21, causing the second extension block 15 to press against the inclined surface of the spring piece 22, allowing the spring piece 22 to pass through the second extension block 15. The contact surface between the spring piece 22 and the second extension block 15 is perpendicular, and the spring piece 22 will abut against the second extension block 15, preventing the limiting member 2 from moving in the opposite direction. This makes it difficult for the limiting member 2 to return to its original position after it has moved to the appropriate position. The limiting member 2 has a better effect in abutting against the bridge pier, avoiding the device from vibrating when the vehicle moves on the bridge. This prevents the limiting member 2 from moving due to vibration, which would result in poor restraint on the bridge pier and serious damage to the bridge pier.

[0059] Please see Figures 2-3 ;

[0060] Both sides of the support member 4 are connected to support rods 41. The support member 4 and the support rods 41 are rotatably connected. The end of the support rod 41 away from the support member 4 extends into the interior of the movable rod 5. The end of the support rod 41 is slidably connected to the movable rod 5.

[0061] As the limiting member 2 moves, the supporting member 4 and the supporting rod 41 are rotatably connected, and the supporting rod 41 inside the supporting member 4 moves inside the moving rod 5, so that one end of the supporting rod 41 always abuts against the moving rod 5. The supporting rod 41 always supports the reinforcing member 1 and the supporting member 4, increasing the support between the reinforcing member 1 and the pier, making the support effect better. It can also be adjusted according to the extension length of the limiting member 2, so that some places will not be difficult to support due to the irregular shape of the pier. This avoids the pier shifting due to poor support effect, resulting in poor support effect of the pier on the bridge and causing the bridge to collapse.

[0062] Please see Figure 5 ,

[0063] A toothed plate 6 is installed inside the movable rod 5. The toothed plate 6 is slidably connected to the inside of the movable rod 5. The right side of the toothed plate 6 extends to form a triangular plate 61. The axial cross-section of the triangular plate 61 is a right triangle. The inclined surface of the triangular plate 61 is the side away from the limiting block 51.

[0064] As the moving rod 5 moves, the toothed plate 6 and the triangular plate 61 inside the moving rod 5 move along with it. The inclined surface of the triangular plate 61 presses against the surface of the limiting member 2, causing the triangular plate 61 to move inward with the toothed plate 6 into the moving rod 5. This causes the teeth on the side of the toothed plate 6 to engage with the inside of the second round hole 42, thus restricting the support rod 41. This effectively prevents the support rod 41 from moving while supporting the limiting member 2 and the pier, and also prevents the second round hole 42 from moving inside the moving rod 5. This would prevent the support rod 41 from effectively supporting the limiting member 2 and the pier, resulting in poor support effect of the device. The pier may tilt or even collapse due to poor support effect, leading to the bridge collapsing without support and causing a major accident.

[0065] Please see Figure 8 ;

[0066] The reinforcing member 1 has a lead screw 7 installed inside it. The reinforcing member 1 and the lead screw 7 are connected by threads. The moving rod 5 has a pressing groove 54 inside it corresponding to the position of the lead screw 7. The cross-sectional shape of the pressing groove 54 is a right trapezoid. The end of the lead screw 7 near the pressing groove 54 is in contact with the inclined surface of the pressing groove 54.

[0067] After adjustment, the lead screw 7 is rotated and moved towards the extrusion groove 54. During the movement, the side wall of the extrusion groove 54 is extruded to drive the moving rod 5, making the movement of the moving rod 5 more convenient. The end of the lead screw 7 extends out of the upper bottom surface of the extrusion groove 54 to fix the moving rod 5, making the movement of the moving rod 5 more convenient and driving the limiting block 51 to move more conveniently. This makes the movement of the moving rod 5 more stable and effectively prevents the moving rod 5 from deviating, which would make it difficult for the limiting block 51 to be inserted into the groove 24, resulting in poor device stability.

[0068] Please see Figure 4 and Figure 7 ;

[0069] One end of the limiting member 2 is equipped with a support member 4. The limiting member 2 is fixedly connected to the support member 4. The support member 4 has a second circular hole 42 inside. The limiting member 2 has a first circular hole 23 inside corresponding to the position of the second circular hole 42. The second circular hole 42 and the first circular hole 23 are connected.

[0070] After the fixing is completed, epoxy resin mortar is injected through the first circular hole 23, allowing it to reach the second circular hole 42. Since the support 4 is located at the crack in the pier, it is easier to inject the epoxy resin mortar into the crack. By using both support and crack filling methods, the repair effect on the pier is better. The two methods increase the support effect and prevent the crack from widening. The two effects complement each other, making the reinforcement of the pier more solid. This avoids the hidden dangers that may result from using only one reinforcement method, which could lead to pier displacement and crack widening, causing the pier to collapse and the bridge to collapse.

[0071] A method for reinforcing a bridge structure using a reinforcement mold includes the following steps: concrete base treatment, erection, support, and crack reinforcement.

[0072] S1: Concrete base treatment. For the missing parts of the component that have been chiseled, removed and exposed reinforcement, repair and restore them with concrete surface defect repair material to achieve a smooth surface. Grind the protruding parts of the component surface to make it smooth as much as possible after repair. For the corners, grind them into rounded corners with a grinder. The radius of the rounded corners must be no less than 30mm. Use a blower to clean the surface dust and debris, or wash with water.

[0073] S2: Erection, by measuring the length of the reinforcement 1 and the perimeter of the pier, as well as the location of the crack in the pier, then the limiting member 2 is passed through the mounting groove 14, and the support member 4 is fixed on one side of the limiting member 2 with bolts. By increasing the number of reinforcement members 1, the overall length of the device is adjusted to better suit piers of different sizes and shapes, so that the device is wrapped around the surface of the pier, and the top and bottom of the reinforcement member 1 provide auxiliary support for the bridge. The limiting member 2 is inserted into the interior of the reinforcement member 1.

[0074] S3: Adjustment, by moving the limiting member 2, the support member 4 is pressed against the position of the pier crack, the support rod 41 moves inside the moving rod 5, the screw 7 is rotated, the moving rod 5 moves downward, so that the moving rod 5 with the limiting block 51 is inserted into the groove 24, the limiting member 2 presses against the triangular plate 61, the triangular plate 61 extends into the moving rod 5 through the toothed plate 6 to fix the support rod 41, the support rod 41 supports the pier, and fixes the limiting member 2;

[0075] S4: Crack reinforcement is achieved by injecting epoxy resin mortar into the spring piece 22, allowing the epoxy resin mortar to reach the crack location through the spring piece 22 and the second round hole 42, and repairing the crack through the second round hole 42.

[0076] Working principle: The number of reinforcement components 1 is adjusted by measuring the length of the bridge pier. The mounting block 12 is removed, exposing the first extension block 11. To increase the number of reinforcement components 1, the mounting block 12 on one side of another reinforcement component 1 is placed next to the first extension block 11 on the same side of this reinforcement component 1. The first extension block 11 is then connected to the mounting block 12 by bolts. Repeating this process allows for the addition of multiple reinforcement components 1 to change the length of the device. Multiple reinforcement components 1 are connected by rotating cylinder 3. Because the device is a flexible structure, it fits more tightly against the bridge pier. Moving the limiting member 2 causes one side of the limiting member 2, along with the support member 4, to abut against the side wall of the bridge pier. This support to the side wall of the bridge pier improves the support effect. The moving rod 5... As the limiting block 51 moves downwards, it moves to the inside of the groove 24. The limiting block 51 restricts the groove 24, fixing the limiting member 2 in this position, making fixing easier. Since the limiting member 2 is movable and multiple grooves 24 are provided, it can fix irregularly shaped piers, broadening its applicability. The length of the limiting member 2 can be adjusted according to the shape of the pier without needing to insert it into the mounting slot 14. This allows for observation of the pier's interior. Simultaneously, the second extension block 15 moves inside the second slide groove 21, pressing the inclined surface of the spring piece 22, allowing the spring piece 22 to pass through the second extension block 15. The spring piece 22 of the second extension block 15 interacts with... The contact surface of the second extension block 15 is a vertical surface. The spring piece 22 will abut against the second extension block 15 to prevent the limiting member 2 from moving in the opposite direction. When the limiting member 2 moves, the support member 4 is rotatably connected to the support rod 41, and the support rod 41 inside the support member 4 moves inside the moving rod 5, so that one end of the support rod 41 always abuts against the moving rod 5. The support rod 41 always supports the reinforcement member 1 and the support member 4, increasing the support between the reinforcement member 1 and the pier. After the adjustment is completed, the lead screw 7 is rotated, and the lead screw 7 moves towards the extrusion groove 54 while rotating. During the movement, the side wall of the extrusion groove 54 is extruded to drive the moving rod 5 to move, making the movement of the moving rod 5 more convenient. The end of the lead screw 7 extends out of the upper bottom surface of the extrusion groove 54. The moving rod 5 is used to fix the moving rod 5. The moving rod 5 moves with the limiting block 51, and the moving limiting block 51 moves the extension rod 511. One side of the extension rod 511 extends to form a triangular block 512, and the triangular block 512 is on the same vertical plane as the limiting wheel 31. By moving the moving rod 5, the moving rod 5, along with the triangular block 512, extends into the interior of the limiting wheel 31. By limiting the limiting wheel 31, the cylinder 3 is restricted, preventing the cylinder 3 from rotating and preventing the multiple reinforcing parts 1 from rotating. The toothed plate 6 and the triangular plate 61 inside the moving rod 5 move with the moving rod 5. The inclined surface of the triangular plate 61 presses against the surface of the limiting part 2, causing the triangular plate 61, along with the toothed plate 6, to move into the interior of the moving rod 5, so that the teeth on the side of the toothed plate 6 engage with the interior of the second circular hole 42.The support rod 41 is restrained to effectively prevent it from moving when supporting the restraining member 2 and the pier. After fixing, epoxy resin mortar is injected through the first circular hole 23, allowing it to reach the second circular hole 42. Since the support member 4 is located at the crack in the pier...
