Description

Technical Field

[0001] The present invention relates to the field of earthquake-resistant reinforcement in construction, and in particular to an earthquake-resistant reinforcement structure for a building wall and a construction method thereof. Background Art

[0002] Earthquake-resistant reinforcement of buildings refers to the structural strengthening of buildings during the construction process to improve their safety and stability under earthquakes and avoid or reduce the damage caused by earthquakes.

[0003] Common seismic reinforcement methods include: ① Adding seismic walls or braces: Adding reinforced concrete seismic walls or steel braces to a frame structure improves the structure's ability to resist lateral displacement, such as adding concrete walls to an open room to share seismic forces. ② Structural system modification: Transforming a mixed structure (such as brick-concrete) into a "constrained masonry structure" by adding structural columns and ring beams to enhance its integrity. ③ Applying carbon fiber cloth / steel plates: Applying high-strength fiber cloth or steel plates to the surfaces of beams and columns to increase bearing capacity (for example, applying carbon fiber cloth to the bottom of a beam to resist bending failure). ④ Enlarging the cross-section: Encasing beams and columns in concrete, increasing the cross-sectional size and reinforcement, and improving their compressive and flexural resistance. ⑤ Reinforced mesh mortar coating: Laying steel mesh on both sides of the wall and applying cement mortar to enhance the wall's shear strength (suitable for older brick walls). ⑥ Adding structural columns and ring beams: Installing reinforced concrete structural columns at wall junctions and ring beams at floor levels to form a "skeleton" to constrain the wall. ⑦ Foundation reinforcement: When the foundation's bearing capacity is insufficient, methods such as grouting, expanding the foundation's bottom area, or adding pile foundations can be used to prevent foundation settlement or slippage during an earthquake. ⑧ Seismic isolation technology: Seismic isolation bearings (such as rubber bearings) are installed between the foundation and the superstructure to reduce the upward transmission of seismic energy. This technology is suitable for important buildings. ⑨ Energy dissipation and vibration reduction devices: Dampers (such as viscous dampers) are installed in the structure to absorb seismic energy and reduce the amplitude of structural vibration.

[0004] Among them, the solution of adding earthquake-resistant walls or supports has a good earthquake-resistant reinforcement effect, is easy to construct, and is the most widely used. For example, application number 202210824097.2 discloses an earthquake-resistant wall reinforcement structure, which belongs to the field of building structure technology. The present invention includes earthquake-resistant walls, corrugated steel plates and C-shaped steels. The corrugated steel plates are arranged on the surfaces of both sides of the earthquake-resistant wall. The troughs on the two corrugated steel plates are connected by a number of tension screws that penetrate the earthquake-resistant wall. Angle steels are arranged at the connection between the earthquake-resistant wall and the beam. The ends of the corrugated steel plates are welded to the surface of the angle steels. The C-shaped steel cladding is arranged on the left and right ends of the earthquake-resistant wall. The edges of the C-shaped steels are welded to the corrugated steel plates. In the present invention, the overall working performance of the wall is good, the earthquake-resistant performance is excellent, the vertical connection structure of the wall is simple, and the rigidity of the connection nodes and the load transfer are safe and reliable.

[0005] Patent application number 202223525104.3 discloses a seismic reinforcement structure for a tall roof parapet, comprising a parapet body and a reinforcement frame. The reinforcement frame is made of two inverted U-shaped steel wedges welded together. The reinforcement frame is L-shaped and sleeved on the top of the corner of the parapet body. The side walls of the reinforcement frame are penetrated by a plurality of first bolts of the same structure. The rods of the plurality of first bolts located in the reinforcement frame are threadedly slidably penetrated by the side walls of the parapet body. A reinforcement mechanism is provided between the two side walls of the parapet body. Both ends of the plurality of first bolts are threadedly penetrated by first locking nuts of the same structure. A lifting mechanism is provided between the two sides of the inner corner of the reinforcement frame. This improves the seismic resistance of the parapet body and thus minimizes the danger of the parapet body collapsing and falling, causing injuries.

[0006] The above-mentioned earthquake-resistant walls or supports can often only be used in empty rooms and cannot be used in environments such as public passages. The reason is that their supporting structures will take up space and affect traffic, thereby limiting the application scope of the earthquake-resistant walls or supports and requiring improvement.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] Example 1

[0030] like Figure 1-5As shown, a seismic reinforcement structure for a building wall includes seismic walls 3 located at the front and rear sides of the wall, and fixing rods 6. The fixing rods 6 extend through the seismic walls 3 and the wall body and are threadedly connected to the seismic walls 3. A base 5 is provided on the top of the seismic wall 3, fixedly connected to the seismic wall 3, and connected to the support rod 1 via a drive mechanism 4. Nuts 2 are provided at both the front and rear ends of the fixing rod 6, and the nuts 2 are threadedly connected to the fixing rod 6.

[0031] By placing seismic walls 3 in front and behind the wall and connecting them with fixing rods 6, the two seismic walls 3 cooperate to clamp the wall to be reinforced, effectively increasing the wall's strength and seismic resistance. Furthermore, the support rods 1 are normally located at the top, without affecting traffic. In the event of an earthquake, the support rods 1 fall to the ground, effectively supporting the seismic walls 3.

[0032] Example 2

[0033] like Figure 1-5 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: the driving mechanism 4 includes an outer fixing tube 8, the right end of the outer fixing tube 8 is fixedly connected to the base 5, an inner fixing tube 9 is provided inside the outer fixing tube 8, the right end of the inner fixing tube 9 is fixedly connected to the inner ring of the bearing 26, the outer ring of the bearing 26 is fixedly connected to the base 5, a connecting column 13 is provided inside the inner fixing tube 9, the right end of the connecting column 13 is fixedly connected to the inner fixing tube 9, and the left end of the connecting column 13 is fixedly connected to the support rod 1, and a one-way clamping component is provided between the inner fixing tube 9 and the outer fixing tube 8.

[0034] The one-way locking assembly includes multiple fixed shafts 12, which are arranged in a circular array around the inner fixed tube 9. The right end of the fixed shaft 12 is fixedly connected to the base 5. A limit plate 11 is rotatably sleeved on the fixed shaft 12. A lower limit bar 14 is provided at the lower left of the limit plate 11. The lower limit bar 14 is fixedly connected to the outer wall of the inner fixed tube 9. An upper limit bar 16 is provided at the upper right of the limit plate 11. The upper limit bar 16 is fixedly connected to the inner wall of the outer fixed tube 8. A first buffer spring 15 is provided at the upper left of the limit plate 11. The lower end of the first buffer spring 15 is fixedly connected to the limit plate 11, and the upper end of the first buffer spring 15 is fixedly connected to the inner wall of the outer fixed tube 8. A slot 17 is provided at the front end of the top of the limit plate 11. A slider 18 is slidably provided in the slot 17 of the topmost limit plate 11. The slider 18 slides in cooperation with the slot 17. A driving rod 19 is provided above the slider 18. The front end of the driving rod 19 is fixedly connected to the slider 18. The driving rod 19 is located inside the bottom end of the curved tube 25. The driving rod 19 slides in cooperation with the bottom of the curved tube 25. A second buffer spring 20 is sleeved on the driving rod 19. One end of the second buffer spring 20 is fixedly connected to the curved tube 25, and the other end of the second buffer spring 20 is fixedly connected to the driving rod 19. The middle of the curved tube 25 is fixedly connected to the front end of the external fixed tube 8. A funnel 24 is provided above the curved tube 25. The bottom end of the funnel 24 is fixedly connected to the top end of the curved tube 25. A circular ring 21 is provided inside the funnel 24. The outer wall of the circular ring 21 is fixedly connected to the inner wall of the funnel 24. The top surface of the circular ring 21 is provided with multiple grooves 22. Ball bearings 23 are provided in the grooves 22.

[0035] Before an earthquake occurs, the slider 18 is stuck in the slide groove 17, so that the limit plate 11 cannot rotate. Since the lower limit bar 14 presses against the limit plate 11, the inner fixing tube 9 cannot rotate clockwise, thereby preventing the connecting column 13 from rotating clockwise, and further preventing the support rod 1 from rotating clockwise, causing the support rod 1 to hang at the top.

[0036] When an earthquake occurs, the device begins to shake, the ball 23 disengages from the groove 22 and falls into the funnel 24, and then falls into the curved pipe 25. The ball 23 accumulates at the bottom of the curved pipe 25 and pushes the driving rod 19 to move under the action of gravity. The driving rod 19 drives the slider 18 to move, so that the slider 18 disengages from the slide groove 17. At this time, the limit plate 11 can rotate.

[0037] Under the action of gravity, the support rod 1 drives the connecting column 13 and the inner fixed tube 9 to rotate clockwise. When the lower limit bar 14 on the inner fixed tube 9 contacts the limit plate 11 from the left side, it can push the limit plate 11 to rotate counterclockwise, so that the limit plate 11 will not hinder the rotation of the lower limit bar 14, thereby allowing the inner fixed tube 9, the connecting column 13, and the support rod 1 to continue to rotate smoothly.

[0038] When the end of the support rod 1 contacts the ground, the support rod 1, the connecting column 13, and the internal fixing tube 9 no longer rotate, so that the support rod 1 supports the earthquake-resistant wall 3, preventing the earthquake-resistant wall 3 and the wall from shifting and collapsing. At this time, the support rod 1 cannot rotate counterclockwise. The principle is: when the support rod 1 rotates counterclockwise, the connecting column 13 and the internal fixing tube 9 rotate synchronously counterclockwise, so that the lower limit bar 14 on the internal fixing tube 9 contacts the limit plate 11 on the right side of the limit plate 11, pushing the limit plate 11 to rotate clockwise, but because the upper limit bar 16 is against the limit plate 11, the limit plate 11 cannot rotate clockwise, thereby making the internal fixing tube 9 unable to rotate counterclockwise, and then making the connecting column 13 and the support rod 1 unable to rotate counterclockwise, so that the support rod 1 can continue to support the earthquake-resistant wall 3.

[0039] Example 3

[0040] like Figure 1-5 As shown, while all other aspects are identical to those of Example 2, this embodiment differs from Example 2 in that a protective sleeve 7 is provided over the support rod 1, affixed to the support rod 1, and made of sponge. A warning strip 10 is provided directly below the support rod 1 and affixed to the ground. The provision of the protective sleeve 7 prevents the support rod 1 from injuring passersby when the support rod 1 rotates. The provision of the warning strip 10 directly below the support rod 1 serves as a reminder not to place items in the path of the support rod 1.
