Description

Technical Field

[0001] This utility model relates to a seismic reinforcement structure for masonry, belonging to the technical field of masonry reinforcement structure. Background Technology

[0002] In the field of building engineering, masonry structures have long been widely used in residential buildings, office buildings, schools, hospitals and other civil buildings, as well as some industrial ancillary facilities, due to their advantages such as convenient material sourcing, simple construction process, low overall cost and good heat and sound insulation performance. They have become an indispensable and important part of the global building system.

[0003] However, the material properties and structural characteristics of masonry structures themselves result in significant shortcomings in seismic performance. Masonry materials (such as bricks and blocks) have high compressive strength, but extremely low tensile and shear strength, and are brittle. When subjected to earthquakes, they are prone to cracking, crumbling, or even complete collapse due to the shear and bending effects generated by horizontal seismic forces.

[0004] Therefore, there is an urgent need for a building masonry with good tensile and shear resistance to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a seismic-resistant reinforcement structure for masonry buildings, thereby resolving the issues raised in the background section.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a seismic reinforcement structure for masonry, including a first rectangular frame, a second rectangular frame, a masonry body, and an adjustment component for connecting the first rectangular frame and the second rectangular frame; The main body of the masonry is fixedly clamped between the first rectangular frame and the second rectangular frame, and the outer wall of the main body of the masonry is respectively attached to the inner wall of the first rectangular frame and the second rectangular frame; The adjustment assembly includes a main beam plate, an adjustable plate, and a receiving groove. The main beam plate is horizontally fixedly installed at the four corner positions on the outside of the first rectangular frame. The receiving groove is horizontally opened on the side of each main beam plate away from the first rectangular frame. The cavity size of the receiving groove is adapted to the cross-sectional size of the adjustable plate, and the adjustable plate is slidably inserted into the receiving groove. The end of the adjustable plate away from the receiving groove is fixedly installed on the outer wall of the second rectangular frame.

[0007] Preferably, each of the main beam plates has a first strip-shaped hole extending transversely along the length of the main beam plate, and a threaded post is inserted through the first strip-shaped hole. One end of the threaded post is a fixed end and the other end is a threaded end. The fixed end of the threaded post is fixedly connected to the outer wall of the adjustable plate, and the threaded end of the threaded post extends to the side of the main beam plate away from the adjustable plate. A nut for locking the main beam plate and the adjustable plate is threaded onto the threaded end of the threaded post.

[0008] Preferably, the outer wall of the main beam plate is horizontally patterned at both the upper and lower positions of the first strip hole, and a washer is also fitted on the threaded column. The washer is located between the main beam plate and the nut, and the side of the washer closest to the main beam plate is provided with a pattern, which engages with the anti-slip groove.

[0009] Preferably, the outer wall of the main beam plate is provided with a second strip hole horizontally below the first strip hole. The second strip hole is parallel to the first strip hole. A cylinder is slidably inserted into the second strip hole. One end of the cylinder is fixedly connected to the outer wall of the adjustable plate, and the other end of the cylinder is provided with a limiting plate to prevent the cylinder from detaching from the second strip hole.

[0010] Preferably, the upper and lower surfaces of the masonry body are provided with inlay grooves, the groove size of which is adapted to the outer size of the rubber block, and the rubber block is inlaid in each inlay groove, with the outer wall of the rubber block tightly fitted to the inner wall of the inlay groove.

[0011] Preferably, a metal cage is pre-embedded inside the masonry body. The shape of the metal cage is adapted to the internal contour of the masonry body, and multiple protruding burrs are integrally formed on the outer wall of the metal cage. The protruding burrs are evenly distributed along the outer wall of the metal cage, and the protruding burrs are embedded and connected to the internal masonry structure of the masonry body.

[0012] Preferably, a plurality of reinforcing members are fixedly installed inside the metal cage. The plurality of reinforcing members are radially distributed, and both ends of each reinforcing member are fixedly connected to the inner wall of the metal cage. The reinforcing members and the inner wall of the metal cage cooperate to form a triangular support structure, and the plurality of triangular support structures are spaced apart along the length direction of the metal cage.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the outer closed frame formed by the first and second rectangular frames can effectively constrain the horizontal displacement of the masonry body, weaken the shear effect of horizontal seismic force on the masonry, avoid early cracks in the masonry due to insufficient shear strength, and improve the shear and collapse resistance of the masonry from the outside as a whole, directly solving the defect of traditional masonry that is "easily damaged by horizontal force". The metal cage itself possesses excellent tensile and shear strength. When pre-embedded inside the masonry, it can directly serve as the "internal load-bearing skeleton" of the masonry. When the masonry is subjected to seismic shear force, the metal cage can replace part of the masonry to bear the shear force, preventing the masonry from cracking due to insufficient shear strength. When the masonry is subjected to tensile stress due to bending effect, the metal cage can provide tensile support, making up for the tensile weakness of the masonry. At the same time, the protruding burrs and the masonry are interlocked to ensure that the metal cage and the masonry "share the load together", preventing the metal cage from separating from the masonry and causing the internal support to fail. This thoroughly improves the tensile and shear strength of the masonry from the inside, solving the problem that "material strength defects cannot be eradicated" in traditional masonry.

[0017] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-8 This utility model provides a technical solution: a seismic reinforcement structure for masonry, including a first rectangular frame 1, a second rectangular frame 2, a masonry body 15, and an adjustment component for connecting the first rectangular frame 1 and the second rectangular frame 2; The masonry body 15 is fixedly clamped between the first rectangular frame 1 and the second rectangular frame 2, and the outer wall of the masonry body 15 is respectively attached to the inner wall of the first rectangular frame 1 and the second rectangular frame 2; The adjustment assembly includes a main beam plate 3, an adjustable plate 4, and a receiving groove 13. The main beam plate 3 is horizontally fixedly installed at the four corner positions on the outside of the first rectangular frame 1. Each main beam plate 3 has a receiving groove 13 horizontally opened on the side away from the first rectangular frame 1. The cavity size of the receiving groove 13 is adapted to the cross-sectional size of the adjustable plate 4, and the adjustable plate 4 is slidably inserted into the receiving groove 13. The end of the adjustable plate 4 away from the receiving groove 13 is fixedly installed on the outer wall of the second rectangular frame 2. In this embodiment of the utility model, firstly, according to the actual size of the masonry body 15, the second rectangular frame 2 is pushed to drive the adjustable plate 4 to slide laterally in the receiving groove 13 of the main beam plate 3 until the inner walls of the first rectangular frame 1 and the second rectangular frame 2 are completely attached to the outer wall of the masonry body 15, thus completing the clamping and positioning of the masonry body; when an earthquake occurs, the horizontal shear force or vertical impact force on the masonry body 15 will first be transmitted to the outer first rectangular frame 1 and the second rectangular frame 2. The two rectangular frames will further transmit the dispersed force to the main beam plate 3 and the adjustable plate 4 at the four corners. Since the adjustable plate 4 is adapted to the receiving groove 13 and has been locked by the subsequent structure, the force will be evenly diffused along the connection path between the main beam plate and the adjustable plate, avoiding local stress concentration; On the one hand, the sliding fit between the adjustable plate 4 and the receiving groove 13 enables the adaptive clamping of masonry main bodies of a certain size range, breaking the traditional "one-to-one" size limitation of reinforcement structures and improving the versatility of the structure; On the other hand, the outer frame formed by the first and second rectangular frames and the adjustment components constitute an overall support system, which can effectively share the seismic force borne by the main body of the masonry, enhance the overall shear and deformation resistance of the masonry, alleviate the problem of the masonry being prone to cracking due to its high brittleness, and reduce the risk of collapse.

[0019] Please see Figure 3 and Figure 4Furthermore, each main beam plate 3 has a first strip hole 5 extending transversely through it. The first strip hole 5 extends along the length of the main beam plate 3, and a threaded post 6 is inserted through the first strip hole 5. One end of the threaded post 6 is a fixed end and the other end is a threaded end. The fixed end of the threaded post 6 is fixedly connected to the outer wall of the adjustable plate 4, and the threaded end of the threaded post 6 extends to the side of the main beam plate 3 away from the adjustable plate 4. A nut 8 for locking the main beam plate 3 and the adjustable plate 4 is threaded on the threaded end of the threaded post 6. In this embodiment of the present invention, when adjusting the position of the adjustable plate 4, the threaded post 6, which is fixedly connected to the adjustable plate, will slide synchronously with the adjustable plate in the first strip hole 5 along the length direction of the main beam plate 3 until the masonry body 15 is clamped; at this time, the nut 8 is rotated clockwise, and the nut generates axial pressure through the thread engagement with the threaded post 6, squeezing towards the main beam plate 3. When the nut is in contact with the outer wall of the main beam plate, the locking action of the threaded post and the nut fixes the main beam plate 3 and the adjustable plate 4, restricting the relative sliding between the two; when an earthquake occurs, if there is a relative sliding tendency between the main beam plate and the adjustable plate, the thread engagement between the threaded post and the nut will generate anti-slip force, preventing the two from separating and ensuring the stable transmission of force; The precise adjustment of the position of the adjustable plate 4 is achieved through the cooperation of the first strip hole 5 and the threaded column 6, which meets the reinforcement requirements of masonry of different sizes. The locking structure of the threaded column and the nut is firmly connected, which can resist the loosening trend caused by earthquake vibration, avoid the failure of the adjustment component in the earthquake, ensure the stability of the external support system, and further improve the seismic reliability of the masonry main body.

[0020] Please see Figure 3 and Figure 4 Furthermore, the outer wall of the main beam plate 3 is horizontally installed with pattern 9 above and below the first strip hole 5. The threaded column 6 is also fitted with a gasket 7. The gasket 7 is located between the main beam plate 3 and the nut 8, and the side of the gasket 7 closest to the main beam plate 3 is provided with a pattern 9 that engages with the anti-slip groove. In this embodiment of the invention, when tightening the nut 8, the nut first squeezes the washer 7, causing the washer to move towards the main beam plate 3 until the anti-slip groove on the side of the washer near the main beam plate is fully engaged with the pattern 9 above and below the first strip hole 5 on the main beam plate. During this process, the engagement of the anti-slip groove and the pattern prevents the washer from rotating with the nut, so that the axial pressure of the nut can be efficiently converted into the clamping force of the washer on the main beam plate, increasing the static friction between the main beam plate and the washer. When an earthquake causes vibration that leads to a counterclockwise loosening tendency of the nut, the engagement structure of the anti-slip groove and the pattern will generate anti-rotation resistance, and at the same time, the static friction will further inhibit the relative sliding between the washer and the main beam plate, thereby preventing the nut from loosening. It effectively solves the problem of nuts easily loosening due to earthquake vibration in traditional reinforcement structures. Through the interlocking of the pattern and anti-slip groove and the friction enhancement effect of the washer, the vibration resistance of the locking structure is improved, ensuring that the adjustment components remain firmly connected after long-term use or after an earthquake, reducing later maintenance costs and extending the service life of the reinforcement structure.

[0021] Please see Figure 3 Furthermore, the outer wall of the main beam plate 3 is provided with a second strip hole 10 horizontally below the first strip hole 5. The second strip hole 10 is parallel to the first strip hole 5. A cylinder 11 is slidably inserted into the second strip hole 10. One end of the cylinder 11 is fixedly connected to the outer wall of the adjustable plate 4, and the other end of the cylinder 11 is provided with a limiting plate 12 to prevent the cylinder 11 from disengaging from the second strip hole 10. In the embodiments of this utility model, when the adjustable plate 4 is adjusted, the cylinder 11 fixed to the adjustable plate will slide synchronously with the adjustable plate in the second strip hole 10. Since the size of the limiting plate 12 at the other end of the cylinder is larger than the groove width of the second strip hole, it can effectively prevent the cylinder from coming out of the second strip hole and provide guidance for the sliding of the adjustable plate. During an earthquake, the main beam plate 3 and the adjustable plate 4 are subjected to lateral shear force. At this time, the threaded column 6 in the first strip hole 5 mainly bears the axial force generated by locking, while the cylinder 11 will bear part of the lateral shear force. The force is transmitted to the main beam plate through the second strip hole, forming a dual force system of "threaded column resisting axial force + cylinder resisting lateral force", which avoids the threaded column from deforming or breaking due to excessive shear force alone. The adjustable plate is provided with dual guidance to ensure stable adjustment. At the same time, the cooperation between the cylinder and the second strip hole distributes the lateral shear force borne by the threaded column, improves the overall load-bearing capacity of the adjustment assembly, prevents damage to the reinforced structure due to the failure of a single component, further enhances the shear resistance of the masonry main body in earthquakes, and reduces the risk of structural damage.

[0022] Please see Figure 1 Furthermore, the upper and lower surfaces of the masonry body 15 are provided with inlay grooves. The groove size is adapted to the outer size of the rubber block 14, and a rubber block 14 is inlaid in each inlay groove. The outer wall of the rubber block 14 is tightly fitted to the inner wall of the inlay groove. In an embodiment of this utility model, when an earthquake occurs, the masonry body 15 will be subjected to horizontal or vertical vibration impact. It will first come into contact with the rubber blocks 14 embedded in the grooves on the upper and lower end faces of the masonry. The rubber blocks have elastic deformation capabilities and will first absorb a portion of the vibration energy through their own compression or stretching. Then, the remaining energy will be slowly released and transferred to the masonry body, avoiding the vibration energy from being directly concentrated on the masonry. At the same time, the rubber blocks can fill the gaps between the masonry body and the upper and lower floor slabs or other connecting structures, reducing the hard collision between the masonry and the surrounding structures during an earthquake and reducing friction damage.

[0023] By utilizing the elastic buffering properties of rubber, the direct impact of earthquakes on the masonry structure can be effectively reduced, alleviating the problem of masonry being prone to cracking and crumbling due to its high brittleness. At the same time, it avoids hard collisions between the masonry and surrounding structures, reduces additional damage, improves the overall seismic buffering performance of the masonry, and protects the integrity of the masonry structure.

[0024] Please see Figure 1 Furthermore, a metal cage 16 is pre-embedded inside the masonry body 15. The shape of the metal cage 16 is adapted to the internal contour of the masonry body 15, and multiple protruding burrs are integrally formed on the outer wall of the metal cage 16. The protruding burrs are evenly distributed along the outer wall of the metal cage 16, and the protruding burrs are embedded and connected with the internal masonry structure of the masonry body 15. In the embodiments of this utility model, when the masonry body 15 is subjected to shear force or bending force generated by an earthquake, the force will first be transmitted to the metal cage 16 inside the masonry body; the metal cage itself has high tensile and shear strength, which can distribute the concentrated seismic force to the entire frame of the metal cage, avoiding excessive local stress on the masonry and damage; at the same time, the protruding burrs on the outer wall of the metal cage are interlocked with the bricks, blocks and other structures inside the masonry body to form a mechanical interlock, preventing relative sliding between the metal cage and the masonry body, ensuring that the force borne by the masonry body can be efficiently transmitted to the metal cage, and the metal cage and the masonry body jointly bear the load; The tensile and shear strength of the masonry structure is enhanced from the inside, which specifically addresses the deficiency of the masonry material itself in terms of strength. The interlocking structure of the protruding burrs and the masonry improves the bonding strength between the metal cage and the masonry, prevents the internal reinforcement structure from separating from the masonry, and greatly improves the overall deformation resistance of the masonry. This effectively reduces the risk of masonry cracks and collapses during earthquakes and enhances the overall seismic performance of the building.

[0025] Please see Figure 7 and Figure 8 Furthermore, multiple reinforcing bars 17 are fixedly installed inside the metal cage 16. The multiple reinforcing bars 17 are radially distributed, and both ends of each reinforcing bar 17 are fixedly connected to the inner wall of the metal cage 16. The reinforcing bars 17 and the inner wall of the metal cage 16 cooperate to form a triangular support structure, and the multiple triangular support structures are distributed at intervals along the length direction of the metal cage 16. In the embodiments of this utility model, after the seismic force is transmitted to the metal cage 16, the frame of the metal cage will evenly transmit the force to the radially distributed reinforcing members 17 inside; since both ends of each reinforcing member are fixed to the inner wall of the metal cage, the reinforcing members and the inner wall of the metal cage together form a triangular support structure. The triangle has the geometric property of being non-deformable, which can further distribute the transmitted force to each triangular unit. The stability of the triangle resists the bending or torsional deformation of the metal cage caused by the force, ensuring that the frame structure of the metal cage is not destroyed and continuously providing internal support for the masonry main body. The triangular support structure significantly improves the overall stiffness and stability of the metal cage, enhances its resistance to deformation, and enables the internal reinforcement system to withstand greater seismic loads. The radially distributed reinforcement further optimizes the force transmission path, avoids localized stress concentration in the metal cage, provides more reliable support for the masonry main body from the inside, fundamentally improves the seismic performance of the masonry main body, and extends the safe service life of the building.

[0026] The workflow of this embodiment is as follows: First, all components are inspected for appearance and dimensions to confirm that the first rectangular frame 1 and the second rectangular frame 2 are free from deformation and cracks, the cross-sectional dimensions of the main beam plate 3 and the adjustable plate 4 are compatible with the receiving groove 13, the threaded column 6, the nut 8, and the washer 7 are free from thread damage, the protruding burrs on the outer wall of the metal cage 16 are intact, the reinforcing bar 17 is firmly welded to the metal cage, and the rubber block 14 is free from aging and damage, ensuring that all components meet the construction requirements; the masonry main body is a precast structure, and the metal cage 16 needs to be pre-embedded in the design position before pouring to ensure that the shape of the metal cage fits the internal contour of the masonry, and the protruding burrs on the outer wall are completely embedded in the masonry pouring material. After the masonry is cured and formed, the internal foundation reinforcement is completed; Place the pre-treated masonry main body 15 on a flat construction platform. First, fit the first rectangular frame 1 onto one side of the masonry main body, ensuring that the inner wall of the first rectangular frame fits tightly against the outer wall of the masonry. Use temporary supports to fix the position of the first rectangular frame to prevent it from shifting. Take out the second rectangular frame 2 and fit it onto the other side of the masonry main body. At the same time, align the adjustable plate 4 fixed on the outer wall of the second rectangular frame with the receiving groove 13 of the main beam plate 3 at the corner of the first rectangular frame. Slowly push the second rectangular frame so that the adjustable plate slides along the length of the receiving groove. During this process, observe the sliding status of the threaded column 6 and the cylinder 11 fixed on the adjustable plate in the first strip hole 5 and the second strip hole 10 of the main beam plate, respectively, to ensure that there is no jamming. Continue until the inner wall of the second rectangular frame is completely fitted against the outer wall of the masonry main body, thus achieving the initial clamping of the masonry by the outer frame. After initial clamping, the threaded post 6 is locked in place: a washer 7 is fitted onto the threaded end of the threaded post, ensuring that the washer is close to the side of the main beam plate 3, aligned with the pattern 9 above and below the first strip hole 5 on the main beam plate. Then, the nut 8 is rotated clockwise until the nut and the washer are tightly fitted together. The nut is then tightened further to make the anti-slip groove of the washer fully engage with the pattern of the main beam plate. Through the axial pressure of the thread engagement and the anti-slip effect of the pattern-anti-slip groove, the main beam plate and the adjustable plate are firmly locked together, restricting their relative sliding.

[0027] Check the status of cylinder 11 and limiting plate 12 to confirm that the cylinder has no displacement in the second strip hole 10 and the limiting plate 12 is tightly attached to the outer wall of the main beam plate to ensure that the cylinder will not come out of the second strip hole, providing additional lateral support for the outer frame, and together with the threaded column, forming a double fixing system to improve the stability of the frame. After the outer frame is fixed, take out the rubber block 14 and embed it into the inlay groove on the upper and lower end faces of the masonry body 15. When installing, press the rubber block gently to make the outer wall of the rubber block completely and tightly fit with the inner wall of the inlay groove, ensuring no gaps. The installation of the rubber block should cover the entire inlay groove to avoid uneven buffering caused by local gaps, thus completing the buffer connection between the masonry and the surrounding structure, such as the floor slab and foundation. After installation, the overall structure is inspected. The fit between the first and second rectangular frames and the masonry is checked. The frame is shaken by hand to confirm that there is no looseness. The tightness of the nuts 8 is checked to ensure that there is no looseness. The integrity of the rubber block 14 is checked. The metal cage 16 is confirmed to be free of exposure or displacement. After all components meet the design requirements, the construction is completed.
