Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a building renovation and reinforcement structure. Background Technology
[0002] Reinforcing and upgrading the structure of buildings is a key technology in modern construction engineering to ensure the safety of existing buildings, especially for dilapidated and dangerous buildings in areas prone to foundation settlement and earthquakes. Such structures need to improve overall stability through external reinforcement systems while preserving the original building to avoid safety accidents caused by structural failure.
[0003] With the acceleration of urbanization, the problems of aging, insufficient functionality, or substandard seismic performance of existing buildings are becoming increasingly prominent, leading to a significant increase in the demand for building renovation and reinforcement. Currently, building reinforcement technologies mainly include cross-section enlargement, external steel reinforcement, and fiber-reinforced composite material reinforcement, which play an important role in improving the load-bearing capacity and ductility of buildings.
[0004] However, the above-mentioned connection methods have significant defects in long-term geological subsidence or periodic vibration environments. The pull-out strength of the anchoring system decreases over time, the welded joints are prone to fatigue cracks due to stress concentration, the chemical adhesive is corroded by groundwater, which leads to a decrease in adhesion, and the mechanical anchor rods gradually loosen due to micro-displacement caused by vibration, which restricts the durability of the reinforcement effect. Utility Model Content
[0005] The purpose of this application is to provide a building renovation and reinforcement structure, including a building body, a foundation is provided below the building body, a foot is provided on the upper surface of the foundation, a grounding component is provided below the foot, a support beam is fixedly connected to the upper surface of the foot, a plurality of crossbeams are fixedly connected to the inner wall of the support beam, the outer walls of the plurality of crossbeams abut against the outer wall of the building body, and a stabilizing component is provided on the outer wall of the crossbeams.
[0006] The grounding component includes a grounding nail, which is located under the grounding foot. The grounding nail head has a through-hole groove two, and the grounding foot has a through-hole groove one. A connecting nail is located inside the first hole groove, and the connecting nail is located inside the second hole groove. A threaded rod is threadedly connected to the inner wall of the connecting nail. A retaining ring head is fixedly connected to one end of the threaded rod, and the other end of the threaded rod is a tapered head.
[0007] Through the above technical solution, the ground nails penetrate deep into the foundation to form a firm anchor point. The connecting nail passes through the hole groove of the anchor and the ground nail to achieve a preliminary connection. When the threaded rod is screwed into the connecting nail, the conical head squeezes the inclined locking block to make it expand radially. Combined with the elastic force of the spring, it forms a self-locking mechanism. The locking ring head is finally locked, which can significantly enhance the connection strength between the anchor and the foundation and effectively resist the pull-out force caused by geological settlement.
[0008] Furthermore, the stabilizing component includes a movable rod and a clamping block, and a sliding rod is fixedly connected between the plurality of crossbeams. The inner wall of the movable rod is slidably connected to the outer wall of the sliding rod, and the clamping block is slidably connected to the inner wall of the movable rod.
[0009] Through the above technical solution, the slide bar provides a stable sliding track for the moving bar. The moving bar can adjust its lateral position along the slide bar, and the clamping block can adjust its vertical position by sliding inside the moving bar. This allows the clamping block to adapt to the shape of the house body, fit tightly together and play a stabilizing role, thereby improving the stability of the connection between the beam and the house body.
[0010] Furthermore, a rack is provided inside the movable rod, and the outer wall of the clamping block is fixedly connected to the outer wall of the rack.
[0011] Through the above technical solution, the movement of the rack can directly drive the clamping block to move synchronously, ensuring the accuracy and stability of the clamping block displacement, enabling the clamping block to accurately approach the building body and apply pressure, thereby enhancing the stability effect.
[0012] Furthermore, a gear is provided inside the movable rod, and the gear meshes with a rack.
[0013] Through the above technical solution, the meshing transmission of gears and racks can convert the rotational motion of gears into the linear motion of racks, realize the smooth movement of the clamping block, and have high transmission efficiency. It can accurately control the movement distance of the clamping block and ensure uniform clamping force.
[0014] Furthermore, a concave hexagonal head is rotatably connected inside the movable rod, one end of which is fixedly connected to the upper surface of the gear, and a rotating rod is rotatably connected to the inner wall of the concave hexagonal head.
[0015] Through the above technical solution, the rotating rod can drive the concave hexagonal head to rotate, thereby making the gear rotate synchronously, providing power input to the gear, making the operation convenient and labor-saving, and easily driving the gear and rack to cooperate to move the clamping block.
[0016] Furthermore, a locking rod is slidably connected to the inner wall of the rotating rod, and a locking groove is formed on the upper surface of the moving rod, with the locking rod disposed inside the locking groove.
[0017] Through the above technical solution, the position of the rotating rod and gear can be locked after the clamping rod is embedded in the slot, preventing the gear and rack from shifting under the action of external forces such as vibration, ensuring the stability of the clamping block in the clamping state of the house body, and avoiding the loosening of the stabilizing components.
[0018] Furthermore, a slidable locking block is slidably connected to the inner wall of the connecting pin, the outer wall of the slidable locking block abuts against the other end of the threaded rod, and a spring is provided inside the connecting pin, one end of which is fixedly connected to the outer wall of the slidable locking block;
[0019] Through the above technical solution, when the tapered head of the threaded rod presses the inclined block, the spring is compressed to generate elastic force, which causes the inclined block to expand radially and tightly abut against the foundation soil or the inner wall of the ground nail, forming multi-point engagement, enhancing the anchoring force between the connecting nail and the ground nail and the foundation, improving the pull-out resistance, and the spring can drive the inclined block to reset when the threaded rod is screwed out, which is convenient for disassembly and adjustment.
[0020] Furthermore, the outer wall of the support beam is bolted with multiple reinforcing rods, and two reinforcing rods are bolted together.
[0021] Through the above technical solution, the bolted connection between the reinforcing rod and the support beam, as well as between the reinforcing rods, can form a stable triangular support structure, effectively dispersing the lateral force on the support beam, enhancing the support beam's resistance to deformation, and thus improving the stability and seismic performance of the entire reinforced structure. Furthermore, the bolted connection facilitates installation and disassembly, making it convenient for later maintenance and adjustment.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. In this utility model, the grounding component significantly enhances the anchoring strength between the anchor and the foundation through the cooperative self-locking mechanism of the inclined locking block and the spring. When the threaded rod is screwed in, the conical end automatically triggers the radial expansion of the inclined locking block to form a multi-point interlocking structure, which effectively resists the pull-out force caused by geological settlement. The final locking design of the retaining ring head further ensures long-term seismic stability. This structure breaks through the traditional welding reinforcement method and improves the pull-out strength of the foundation connection.
[0024] 2. In this utility model, the stabilizing component innovatively adopts a gear and rack linkage system. Rotation operation can drive the clamping block to adaptively press against the house body. The clamping block displacement accuracy is high, which reduces the stress concentration problem caused by uneven force on the wall in traditional reinforcement. The quick locking mechanism of the clamping rod and the clamping slot shortens the construction time, making it particularly suitable for rapid emergency reinforcement of dilapidated houses.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.
[0035] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a building renovation and reinforcement structure, comprising a building body 1, a foundation 3 provided below the building body 1, the foundation 3 being able to evenly transfer the upper load of the building body 1 to the underground soil layer, reducing the risk of local settlement, a footing 2 provided on the upper surface of the foundation 3, a grounding component provided below the footing 2, a support beam 4 fixedly connected to the upper surface of the footing 2, the support beam 4 being able to disperse the force transmitted by the crossbeam 5 to the footing 2, forming a load-bearing frame for the upper structure, a plurality of crossbeams 5 fixedly connected to the inner wall of the support beam 4, the outer walls of the plurality of crossbeams 5 all abutting against the outer wall of the building body 1, restricting its lateral displacement, enhancing the anti-tilting ability of the building body 1, and a stabilizing component provided on the outer wall of the crossbeam 5;
[0036] The grounding assembly includes a grounding nail 8, which is positioned below the foot 2 to directly transmit the force of the foot 2 to the deep foundation 3. A second hole 9 is formed through the nail head of the grounding nail 8, and a first hole 7 is formed through the foot 2. The first hole 7 and the second hole 9 mate, allowing the connecting nail 11 to simultaneously penetrate the foot 2 and the grounding nail 8, achieving a mechanical connection between them. The connecting nail 11 is located inside the first hole 7 and inside the second hole 9. A threaded rod 12 is threaded onto the inner wall of the connecting nail 11, and the threaded rod 12 engages with the connecting nail 11 for easy screwing and adjustment. One end of the threaded rod 12 is fixedly connected to a retaining ring 10, which locks the position of the threaded rod 12 after tightening, preventing loosening during long-term use. The other end of the threaded rod 12 is a tapered head, which can compress the inclined retaining block 13 during screwing, causing it to expand radially.
[0037] Specifically: When installing the grounding assembly, first drive the ground nail 8 vertically into the foundation 3 to a predetermined depth, so that the first slot 7 of the anchor 2 is precisely aligned with the second slot 9 of the ground nail 8. Then, insert the connecting nail 11 into the first slot 7 and the second slot 9, and then screw in the threaded rod 12. Its conical head will squeeze the inclined locking block 13. The spring 14 is compressed and generates elastic force to push the inclined locking block 13 to expand radially, closely contacting the inner wall of the ground nail 8 and the soil of the foundation 3. Finally, tighten the retaining ring head 10 to lock the threaded rod 12, forming multiple anchoring, which significantly improves the connection strength between the anchor 2 and the foundation 3, and effectively resists the pull-out force caused by geological settlement.
[0038] Figure 1 - Figure 8The stabilizing components include a movable rod 15 and a clamping block 16. Multiple crossbeams 5 are fixedly connected to sliding rods 17, which provide a sliding track for the movable rod 15. The inner wall of the movable rod 15 is slidably connected to the outer wall of the sliding rod 17. The movable rod 15 slides along the sliding rod 17 to adjust the lateral position of the clamping block 16, adapting to different widths of the house body 1. The clamping block 16 is slidably connected to the inner wall of the movable rod 15. A rack 18 is provided inside the movable rod 15, and the outer wall of the clamping block 16 is fixedly connected to the outer wall of the rack 18. A gear 19 is provided inside the movable rod 15, meshing with the rack 18. A concave hexagonal head 20 is rotatably connected inside the movable rod 15, with one end fixedly connected to the upper surface of the gear 19. A rotating rod 21 is rotatably connected to the inner wall of the concave hexagonal head 20, and a locking rod 22 is slidably connected to the inner wall of the rotating rod 21. A slot 23 is provided on the upper surface of the movable rod 15, and the locking rod 22 is located inside the slot 23. The embedded slot 23 can lock the position of the rotating rod 21 and the gear 19 to prevent the stabilizing components from loosening during vibration. The inner wall of the connecting nail 11 is slidably connected to the inclined locking block 13. The outer wall of the inclined locking block 13 abuts against the other end of the threaded rod 12. The inclined locking block 13 abuts against the conical head of the threaded rod 12, which can convert the axial force of the threaded rod 12 into a radial expansion force to achieve a self-locking effect. A spring 14 is set inside the connecting nail 11. One end of the spring 14 is fixedly connected to the outer wall of the inclined locking block 13. The spring 14 is fixed to the inclined locking block 13, which can stably transmit the elastic force and ensure the consistency of the movement of the inclined locking block 13.
[0039] Specifically: When adjusting the stabilizing components, first slide the moving rod 15 along the slide rod 17 to a suitable lateral position, then rotate the concave hexagonal head 20 through the rotating rod 21 to drive the gear 19 and rack 18 to mesh and transmit power, so that the clamping block 16 slides along the inner wall of the moving rod 15 to fit against the outer wall of the house body 1. Finally, press the locking rod 22 into the corresponding locking groove 23 to lock the relative position of the gear 19 and rack 18, ensuring that the clamping block 16 always tightly clamps the house body 1, and preventing the crossbeam 5 from loosening due to vibration.
[0040] Figure 1 - Figure 8 The outer wall of the support beam 4 is connected to multiple reinforcing rods 6 by bolts. The reinforcing rods 6 are bolted to the support beam 4, which facilitates installation and disassembly, and the connection strength is high. They can disperse the lateral force of the support beam 4. Two reinforcing rods 6 are connected by bolts.
[0041] Working principle: When it is necessary to use this type of building renovation and reinforcement structure, firstly, the ground nail 8 is driven vertically into the foundation 3 to a predetermined depth, so that the first groove 7 at the bottom of the foot 2 is precisely aligned with the second groove 9 at the top of the ground nail 8. Then, the connecting nail 11 is inserted into the first groove 7 and the second groove 9. The threaded rod 12 is screwed in so that its conical end pushes the inclined locking block 13. The spring 14 is compressed and causes the inclined locking block 13 to expand radially. Finally, the locking ring head 10 is tightened to complete the foot 2 biting the lower surface of the ground nail 8 to form an anti-pull-out self-locking structure. Then, the support beam 4 is installed on the upper surface of the foot 2. Multiple reinforcement rods 6 are connected to the outer wall of the support beam 4 by bolts to form a triangular stable frame. The crossbeam 5 is fixed to the inner wall of the support beam 4 and its outer wall is attached to the main body of the house 1.
[0042] When adjusting the stabilizing components, the rotating concave hexagonal head 20 drives the gear 19 to rotate. The gear 19 meshes with the rack 18, causing the clamping block 16 to move vertically along the slide bar 17 until the clamping block 16 evenly presses against the outer wall of the house body 1. Finally, the locking rod 22 at the end of the rotating rod 21 is pressed down and embedded into the slot 23 of the moving rod 15 to lock the overall reinforcement structure.
