Description

Technical Field

[0001] The invention belongs to the technical field of wall reinforcement, and in particular relates to a reinforcement device and method for repairing ancient building walls. Background Art

[0002] The screen wall, also known as the screen wall, the wall of the light, and the wall of the Xiao, is a highly decorative wall in the walls of ancient buildings. It is a wall located inside or outside the gate of a building or courtyard, facing the gate and acting as a barrier. In terms of shape, the screen wall is generally not much different from an ordinary wall. It can be divided into three parts: the top of the wall, the body of the wall, and the upper and lower parts of the wall seat. In terms of building materials, the screen wall mainly includes glazed screen walls, stone screen walls, brick screen walls, and wooden screen walls. The side of the screen wall facing the gate is basically decorated with exquisite carvings. However, many screen walls have collapsed due to instability or insufficient strength due to disrepair over the years. Take the screen wall of the Mongolian Zhenwang Mansion as an example. It is a brick and stone structure. Due to disrepair over the years, cracks appeared in the wall and the blue tiles fell off, which posed a risk of collapse.

[0003] In the existing wall repair technology, when the wall has problems with stability or insufficient strength, the wall is often reinforced by adding masonry buttresses. However, this method is not applicable to the screen wall in ancient buildings. This is mainly because the screen wall is equipped with exquisite carvings. When the traditional method of adding masonry buttresses is used to reinforce it, it is very easy to cause damage to the carvings. What's more, many screen walls are affected by their historical age and have certain cultural relics. They are also protected objects. The traditional method of adding masonry buttresses requires adding buttresses to the original wall. That is, a batch of bricks will be chiseled off at a certain distance along the height of the wall to form horizontal grooves. This will also damage the screen wall, and its historical value, scientific value and artistic value, making it impossible to maintain its original appearance. Summary of the invention

[0004] In view of the above-mentioned problems, the purpose of the present invention is to provide a reinforcement device and method for repairing the walls of ancient buildings, which can ensure the original appearance of the screen wall while reinforcing the screen wall and effectively avoid damage to the screen wall.

[0005] The technical solution of the present invention is: a reinforcement device for repairing the wall of an ancient building, which is used to reinforce the screen wall, and includes a column part, a clamping part, a beam part and a supporting part. The column part includes two bases and two columns, and the two bases are used to be buried underground, one of which is located on one side of the screen wall, and the other is located on the other side of the screen wall. The two columns are respectively arranged on the bases in a one-to-one correspondence, close to the two sides of the screen wall, and a groove one is arranged on the column. The clamping part is distributed on the column, and each column corresponds to at least two clamping parts, and each clamping part includes a basic block, two mounting plates and two clamping plates. The basic block is slidably arranged in the groove one and fixed on the column, and the two mounting plates are relatively arranged on the basic block. The two clamping plates are arranged on the mounting plate in a one-to-one correspondence, and the clamping plate is used to clamp the two sides of the screen wall. The beam part includes at least two beams, and the two beams are arranged between the mounting plates corresponding to the positions on the two columns, and are located on the back side of the screen wall. The supporting part comprises a plurality of supporting plates, one side of the supporting plates is arranged on the beam body, and the other side is used for supporting the back of the screen wall.

[0006] The base is used to provide a stable foundation for the entire reinforcement device. In the specific implementation, a prefabricated concrete base is used, which can effectively resist the impact of factors such as ground settlement on the screen wall and ensure the stability of the screen wall during long-term use. The two columns are close to both sides of the screen wall, further enhancing the lateral support of the screen wall, reducing the risk of the screen wall tilting or collapsing due to external factors, and connecting with the screen wall with the clamping part, and supporting the screen wall through the support plate, greatly improving the bearing capacity of the screen wall.

[0007] Each column has at least two clamping parts, and the base block of the clamping part can be slidably arranged in the groove of the column and fixed, so that the clamping part can be flexibly adjusted according to the specific size and shape of the screen wall to better fit the screen wall. The two L-shaped mounting plates arranged opposite to each other increase the stability of the clamping structure, and the two clamping plates clamp the two sides of the screen wall, which can limit the displacement of the screen wall from the side and provide effective overall support for it.

[0008] The beam body of the beam part is arranged between the corresponding mounting plates on the two columns, and is located on the back side of the screen wall, providing lateral support for the screen wall. Multiple support plates are arranged on one side of the beam body, and support the back of the screen wall on the other side, forming a three-dimensional support structure, providing strong support for the screen wall from the back, effectively sharing the weight of the screen wall itself and possible external forces, and enhancing the overall stability of the screen wall.

[0009] The columns, clamps, beams and supports work together to form an all-round, multi-level reinforcement system. From the base support to the side clamps and back support, all parts work together to provide comprehensive and effective reinforcement for the screen wall, protecting the screen wall to the greatest extent so that it can exist stably for a long time after restoration, extending its service life and better protecting the cultural heritage of ancient buildings.

[0010] What's more, each component is modularly designed. For example, the base block of the clamping part can be slid in groove one and then fixed with bolts, which makes it easy to flexibly adjust the position according to the actual situation of the screen wall during installation. The installation process of the overall device is relatively simple, which can improve construction efficiency and facilitate the maintenance and adjustment of the reinforcement device at a later stage.

[0011] Furthermore, the column is a prefabricated concrete column, which includes a steel member and a concrete layer. The cross section of the steel member is an I-shaped or C-shaped structure, the concrete layer is sleeved outside the steel member, and together with the steel member, forms a foundation column with a rectangular cross section; the groove one is located on the side of the foundation column away from the screen wall, and the foundation block is slidably arranged in the groove one and fixed on the steel member.

[0012] Among them, the I-shaped or C-shaped structure of the steel member can provide a transverse flange portion for arranging screw holes three for connecting the foundation block when it is laid out, that is, screw holes three are set on the column, and screw holes three penetrate the flange of the I-shaped or C-shaped steel member, and the foundation block is fixed to the screw holes three by bolts so that it is not only fixed to the external concrete layer, but also to the internal steel member, and has strong and high strength and good toughness. In this embodiment, there are multiple screw holes three, which are arranged in the groove one at intervals along the height direction of the column. In actual use, screw holes three of different heights are selected according to the actual repair position to fix the foundation block. What's more, the I-shaped structure is widely used in the construction field because it performs well in bending and shear resistance and can effectively withstand external forces from different directions; the C-shaped structure is relatively flexible, and in some specific stress conditions, it can provide a larger bearing capacity with a smaller deadweight. The steel member can bear the main tensile force and part of the pressure, prevent the column from suddenly breaking when stressed, and provide a basic structural skeleton for the column. Among them, the steel member of this embodiment adopts I-beam.

[0013] The concrete layer is set outside the steel component, which can give full play to the good compressive resistance of concrete and withstand large vertical pressure. At the same time, it protects the internal steel components from erosion by the external environment and improves the durability of the column. During long-term use, the concrete layer can prevent the steel components from rusting and corroding, extend the service life of the column, and ensure that the reinforcement device can function stably and long-term. The steel component and the concrete layer work together to form a whole, jointly bearing various loads, so that the column has high strength, toughness and durability, and can better adapt to the complex stress environment and long-term use requirements of the ancient building screen wall reinforcement project. In addition, the column can be prefabricated and has the convenience of production and use. During the prefabrication process, the position and size of the groove can be accurately set to ensure that the foundation block can be accurately and smoothly slid and installed in the groove and fixed on the steel component.

[0014] Furthermore, a limit block is provided in the groove one, and the limit block is used to limit the base block to prevent it from falling out of the groove one. The limit block can prevent the base block from accidentally falling out of the groove one, and ensure the stable connection between the clamping part and the column. The clamping part is a key component for clamping the side of the screen wall, and its stable connection is crucial to the reliability of the entire reinforcement device. If the base block falls off, the clamping plate will not be able to effectively clamp the screen wall, which may cause the screen wall to lose lateral constraints and increase the risk of tilting or collapse.

[0015] Furthermore, the clamping plate is arranged on the mounting plate through an adjusting member, and the adjusting member includes an extension plate and a fixing screw. The extension plate is fixed on the mounting plate, and a screw hole 1 is arranged on the extension plate, and a screw hole 2 corresponding to the position of the screw hole 1 is arranged on the clamping plate, and the fixing screw is passed through the screw hole 1 and the screw hole 2 and fixed by a nut, so as to fix the clamping plate on the extension plate.

[0016] Furthermore, the adjusting member also includes an adjusting gasket, which is arranged on the fixing screw and located between the clamping plates.

[0017] Since the screen walls of different ancient buildings may have differences in size and shape, the relative position between the clamping plate and the mounting plate can be adjusted through the adjustment parts, specifically by using the cooperation of the fixed screw with the extension plate and the screw hole, and with the help of the adjustment gasket. When facing screen walls of different thicknesses or uneven surfaces, the construction workers can flexibly adjust the position of the clamping plate by loosening the nut, moving the clamping plate, placing the adjustment gasket, and then re-tightening the nut, so that the clamping plate fits tightly against the front and back of the side of the screen wall to ensure the reinforcement effect.

[0018] Furthermore, a mounting rod is arranged on the support plate, a thread is arranged on the outer side of the mounting rod, a second groove is arranged on the beam body, the mounting rod is slidably arranged in the second groove, and the mounting rod is fixed on the beam body by tightening the first nut.

[0019] The mounting rod can slide in the second groove. When installing the support plate, the construction personnel can quickly align the mounting rod with the second groove and slide along the second groove to adjust the position of the support plate so that it can accurately fit the different positions on the back of the screen wall. This design reduces the difficulty of alignment during the installation process and improves the installation efficiency, which greatly facilitates the construction personnel's work, especially when the construction site has limited space and inconvenient operation. The mounting rod and the beam body are fixed by tightening the nut one, without complicated welding or other special processes, and only ordinary tools are needed to complete the operation, which makes the construction process simpler and reduces the requirements for the professional skills of the construction personnel. At the same time, it also shortens the installation time and can speed up the progress of the entire reinforcement project.

[0020] In addition, the sizes of screen walls of different ancient buildings are different, and the shapes of the backs of screen walls of different ancient buildings may be irregular. By sliding the mounting rod in groove 2, the support plate can flexibly adjust its position to better fit the curved or uneven surface of the back of the screen wall. This feature enables the reinforcement device to adapt to a variety of different forms of screen walls, enhancing the versatility and adaptability of the device.

[0021] During the installation process, construction workers can fine-tune the position and support depth of the support plate by loosening or tightening nuts according to the actual stress conditions of the screen wall, thereby adjusting the support strength of the support plate on the back of the screen wall, ensuring that each support plate can effectively share the weight of the screen wall and optimize the overall reinforcement effect.

[0022] Furthermore, the mounting rod is provided with a reinforcing rib, which is used to support the support plate. The reinforcing rib can increase the connection rigidity between the support plate and the mounting rod, effectively disperse the pressure from the screen wall borne by the support plate, and when the weight of the screen wall or the external force applied to the support plate, the reinforcing rib can assist the mounting rod to share the load, so that the support plate can significantly improve the bearing capacity without increasing its own thickness or weight, thereby more firmly supporting the screen wall and ensuring the reinforcement effect. In addition, during the long-term use of the reinforcement device, the support plate is continuously subjected to pressure and is prone to deformation. The presence of the reinforcing rib limits the deformation trend of the support plate when subjected to force, maintains its shape stability, maintains effective support for the screen wall, and extends the service life of the support plate. The reinforcing rib changes the stress distribution state at the connection between the support plate and the mounting rod. In the absence of the reinforcing rib, the stress may be concentrated near the contact point between the mounting rod and the support plate, which may easily cause premature damage to the area. The setting of the reinforcing rib enables the stress to be more evenly diffused to the entire connection area, reduces the stress concentration phenomenon, improves the overall mechanical properties of the structure, and reduces the risk of structural failure caused by stress concentration.

[0023] Furthermore, the reinforcing rib comprises a collar, a plurality of rib plates and a second fastening nut. The collar is sleeved on the mounting rod, the plurality of rib plates are arranged on the outer side wall of the collar at intervals along the circumferential direction of the collar center axis, and the second fastening nut is sleeved on the mounting rod and is located on a side of the collar away from the mounting rod, and is used to limit the collar so that the rib plates are close to the support plate.

[0024] Multiple ribs are arranged at intervals along the circumferential direction of the center axis of the collar. This layout allows the support plate to obtain uniform support force in all directions. When the pressure of the screen wall acts on the support plate, the ribs can disperse the pressure from different angles to prevent the support plate from being deformed or damaged due to local uneven force, effectively improving the bearing capacity and stability of the support plate. In actual use, the support plate can be further reinforced by rotating the collar so that the reinforcing ribs are at different positions on the support plate. It can be selectively adjusted according to the actual repair position, and tightened with nut two after adjusting the position of the reinforcing ribs.

[0025] Furthermore, it also includes a stabilizing part, which is arranged between two adjacent beams and includes a vertical rod, a bonding plate and four connecting rods. The vertical rod is vertically arranged between two adjacent beams, and its two ends are respectively fixed on the two beams, the bonding plate is fixed on the vertical rod, one side of the bonding plate is arranged on the vertical rod, and the other side is bonded to the back of the screen wall for supporting the back of the screen wall, and the four connecting rods are distributed in an X shape, one end is fixed to the bonding plate, and the other end is fixed to the beam.

[0026] The vertical rods, laminating plates and connecting rods of the stabilizing part cooperate with each other to form a coordinated support system. The laminating plates directly support the screen wall, the vertical rods transfer the supporting force of the laminating plates to the beam body, and the X-shaped connecting rods further strengthen the transmission and dispersion of this force. This coordinated working method allows the pressure on the screen wall to be more evenly dispersed throughout the reinforcement device, improving the supporting effect of the screen wall and enhancing the stability and safety of the screen wall.

[0027] The setting of the stabilizing part changes the stress state of the reinforcement device, so that the force originally concentrated on the beam and the support plate can be distributed more reasonably. The existence of vertical rods and connecting rods increases the redundancy of the structure, and improves the bearing capacity and anti-deformation ability of the structure. When facing complex stress conditions, the stabilizing part can better coordinate the forces between the components, avoid weak links, and ensure the safety and reliability of the reinforcement device during long-term use. The stabilizing part forms an organic whole for the entire reinforcement device. This integrity not only improves the stability and bearing capacity of the structure, but also enhances the seismic performance of the structure. When natural disasters such as earthquakes occur, the stabilizing part can effectively disperse the seismic force to various components, reduce the degree of damage to the structure, and protect the safety of the screen wall of the ancient building.

[0028] A reinforcement method for repairing the walls of ancient buildings, wherein the reinforcement device performs reinforcement, including: burying a base underground on both sides of a screen wall, arranging columns close to both sides of the screen wall, clamping both sides of the screen wall with clamping plates, and supporting the back of the screen wall with supporting plates.

[0029] Compared with the prior art, the beneficial effect of the present invention is that the column part provides a foundation for supporting the screen wall, and the clamping part, beam part and support part cooperate with each other to form an all-round and multi-level reinforcement system. Among them, since the clamping part clamps the front and back of both sides of the screen wall, and the beam part cooperates with the support part to support the back of the screen wall, the whole will not have too much contact with the front side of the screen wall, which effectively ensures that the carvings on the front side of the screen wall will not be damaged by reinforcement, and the original appearance of the screen wall is guaranteed.

[0030] In addition, the various parts of the present invention, from the base support to the side clamping to the back support, work together to provide comprehensive and effective reinforcement for the screen wall, thereby protecting the screen wall to the greatest extent so that it can exist stably for a long time after repair, extending its service life, and better protecting the cultural heritage of ancient buildings.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0035] Example 1 like Figure 1 , Figure 2 The reinforcement device for repairing the wall of an ancient building shown is used to reinforce the screen wall, and includes a column part 1, a clamping part 2, a beam part 3 and a supporting part 4.

[0036] The column part 1 includes two bases 11 and two columns 12. The two bases 11 are used to be buried underground and located on both sides of the screen wall, one of which is located on one side of the screen wall, and the other is located on the other side of the screen wall. The two columns 12 are respectively arranged on the bases 11 in a one-to-one correspondence, close to both sides of the screen wall, and a groove 120 is arranged on the column 12.

[0037] The clamping parts 2 are distributed on the column 12, and each column 12 corresponds to at least two clamping parts 2. Each clamping part 2 includes a base block 21, two mounting plates 22 and two clamping plates 23. The base block 21 is slidably arranged in the groove 120 and fixed on the column 12. The two mounting plates 22 are relatively arranged on the base block 21. The two clamping plates 23 are arranged on the mounting plates 22 in a one-to-one correspondence. The clamping plates 23 are used to clamp the two sides of the screen wall. It should be noted that: Figure 4 , Figure 5 As shown, the cross section of the mounting plate 22 is an L-shaped structure, one end of the L-shaped structure is arranged on the base block 21 , and the other end of the L-shaped structure is used for mounting the clamping plate 23 .

[0038] The beam portion 3 includes at least two beam bodies 30 . The two beam bodies 30 are arranged between the mounting plates 22 at corresponding positions on the two columns 12 , and are located on the back side of the screen wall.

[0039] The supporting part 4 includes a plurality of supporting plates 40 , one side of the supporting plates 40 is disposed on the beam body 30 , and the other side is used to support the back of the screen wall.

[0040] Among them, the base 11 is used to provide a stable foundation for the entire reinforcement device. In the specific implementation, a prefabricated concrete base is used, which can effectively resist the impact of factors such as ground settlement on the screen wall, ensuring the stability of the screen wall during long-term use. The two columns 12 are close to both sides of the screen wall, further enhancing the lateral support of the screen wall, reducing the risk of the screen wall tilting or collapsing due to external factors, cooperating with the clamping part 2 to connect with the screen wall, and supporting the screen wall through the support plate 40, greatly improving the bearing capacity, anti-displacement stiffness and ductility of the screen wall.

[0041] Each column 12 corresponds to at least two clamping parts 2, and the base block 21 of the clamping part 2 can be slidably arranged in the groove 120 of the column and fixed, so that the clamping part 2 can be flexibly adjusted according to the specific size and shape of the screen wall to better fit the screen wall. The two L-shaped mounting plates 22 arranged opposite to each other increase the stability of the clamping structure, and the two clamping plates 23 clamp the two sides of the screen wall, which can limit the displacement of the screen wall from the side and provide effective overall support for it.

[0042] The beam body 30 of the beam portion 3 is arranged between the mounting plates 22 corresponding to the positions on the two columns 12, and is located on the back side of the screen wall, providing lateral support for the screen wall. Multiple support plates 40 are arranged on the beam body 30 on one side, and support the back of the screen wall on the other side, forming a three-dimensional support structure, providing strong support for the screen wall from the back of the screen wall, effectively sharing the weight of the screen wall itself and possible external forces, and enhancing the overall stability of the screen wall.

[0043] The column 1, the clamping part 2, the beam 3 and the supporting part 4 cooperate with each other to form an all-round, multi-level reinforcement system. From the basic support to the side clamping and then to the back support, each part works together to provide a comprehensive and effective reinforcement for the screen wall, protecting the screen wall to the greatest extent so that it can exist stably for a long time after restoration, extending its service life and better protecting the cultural heritage of the ancient building.

[0044] Moreover, each component is modularly designed. For example, the base block 21 of the clamping part 2 can be slid in the groove 120 and then fixed with bolts, which makes it easy to flexibly adjust the position according to the actual situation of the screen wall during installation. The installation process of the overall device is relatively simple, which can improve the construction efficiency and is also convenient for the later maintenance and adjustment of the reinforcement device.

[0045] Preferably, Figure 3 , Figure 4As shown, the column 12 is a prefabricated concrete column, which includes a steel member 121 and a concrete layer 122. The cross section of the steel member 121 is an I-shaped or C-shaped structure, and the concrete layer 122 is sleeved outside the steel member 121 to form a foundation column with a rectangular cross section together with the steel member 121; the groove 120 is located on the side of the foundation column away from the screen wall, and the foundation block 21 is slidably arranged in the groove 120 and fixed on the steel member 121.

[0046] Among them, the I-shaped or C-shaped structure of the steel member 121 can provide a transverse flange portion for arranging screw holes three for connecting the foundation block 21 when it is laid out, that is, screw holes three are set on the column 12, and the screw holes three penetrate the flange of the I-shaped or C-shaped steel member 121, and the foundation block 21 is fixed to the screw holes three by bolts so that it is not only fixed to the external concrete layer 122, but also fixed to the internal steel member 121, and has strong and high strength and good toughness. In this embodiment, there are multiple screw holes three, which are arranged in the groove 120 at intervals along the height direction of the column 12. In actual use, screw holes three of different heights are selected according to the actual repair position to fix the foundation block 21. What's more, the I-shaped structure is widely used in the construction field because it performs well in bending and shear resistance and can effectively withstand external forces from different directions; the C-shaped structure is relatively flexible, and in some specific stress conditions, it can provide a larger bearing capacity with a smaller deadweight. The steel member 121 can bear the main tensile force and part of the compressive force, prevent the column 12 from breaking suddenly when subjected to force, and provide a basic structural framework for the column 12. In this embodiment, the steel member 121 is an I-beam.

[0047] The concrete layer 122 is set outside the steel member 121, which can give full play to the good compressive resistance of concrete, withstand large vertical pressure, and protect the internal steel member 121 from erosion by the external environment, thereby improving the durability of the column 12. During long-term use, the concrete layer can prevent the steel member from rusting and corroding, extend the service life of the column, and ensure that the reinforcement device can play a role in a long-term and stable manner. The steel member 121 and the concrete layer 122 work together to form a whole, and jointly withstand various loads, so that the column 12 has high strength, toughness and durability, and can better adapt to the complex stress environment and long-term use requirements of the ancient building screen wall reinforcement project. In addition, the column 12 can be prefabricated and has the convenience of production and use. During the prefabrication process, the position and size of the groove 120 can be accurately set to ensure that the foundation block 21 can be accurately and smoothly slid and installed in the groove 120 and fixed on the steel member 121.

[0048] Preferably, Figure 3As shown, a limit block 1200 is provided in the groove 120, and the limit block 1200 is used to limit the base block 21 to prevent it from falling out of the groove 120. The limit block 1200 can prevent the base block from accidentally falling out of the groove 1, and ensure the stable connection between the clamping part 2 and the column 12. The clamping part 2 is a key component for clamping the side of the screen wall, and its stable connection is crucial to the reliability of the entire reinforcement device. If the base block 21 falls off, the clamping plate 23 will not be able to effectively clamp the screen wall, which may cause the screen wall to lose lateral constraints, increasing the risk of tilting or collapse.

[0049] It should be noted that the limit block 1200 is already set when the column is prefabricated. When installing the base block 21, the construction personnel do not need to take additional complicated measures to prevent it from falling off. They only need to slide the base block 21 from the end of the column 12 into the groove 120. When in use, the base block 21 is slid to a suitable position, and the base block 21 is fixed with bolts at the screw hole 3 closest to the base block 21, which greatly improves the construction efficiency.

[0050] Preferably, Figure 5 As shown, the clamping plate 23 is arranged on the mounting plate 22 through the adjusting member 24, and the adjusting member 24 includes an extension plate 241 and a fixing screw 242. The extension plate 241 is fixed on the mounting plate 22, and is provided with a screw hole 1, and the clamping plate 23 is provided with a screw hole 2 corresponding to the position of the screw hole 1, and the fixing screw 242 is passed through the screw hole 1 and the screw hole 2 and fixed by a nut, so as to fix the clamping plate 23 on the extension plate 241.

[0051] Preferably, the adjusting member 24 further includes an adjusting gasket, which is disposed on the fixing screw 242 and located between the clamping plate 23 and the extension plate 241 .

[0052] Since the screen walls of different ancient buildings may have differences in size and shape, the relative position between the clamping plate 23 and the mounting plate 22 can be adjusted through the adjustment member 24, specifically by using the cooperation of the fixing screw 242, the extension plate 241 and the screw hole 1, and with the help of the adjustment gasket. When facing screen walls of different thicknesses or uneven surfaces, the construction workers can flexibly adjust the position of the clamping plate 23 by loosening the nut, moving the clamping plate 23, placing the adjustment gasket, and then re-tightening the nut, so that the clamping plate 23 is closely attached to the front and back of the side of the screen wall to ensure the reinforcement effect.

[0053] Preferably, Figure 6 As shown, a mounting rod 41 is provided on the support plate 40, and a thread is provided on the outer side of the mounting rod 41. A groove 2 300 is provided on the beam body 30, and the mounting rod 41 is slidably set in the groove 2 300. The mounting rod 41 is fixed to the beam body 30 by tightening the nut 1.

[0054] The mounting rod 41 can slide in the second groove 300. When installing the support plate 40, the construction personnel can quickly align the mounting rod 41 with the second groove 300 and slide and adjust the position of the support plate 40 along the second groove 300 so that it can accurately fit different positions on the back of the screen wall. This design reduces the difficulty of alignment during the installation process and improves the installation efficiency, which greatly facilitates the construction personnel's work, especially when the construction site space is limited and the operation is inconvenient. The mounting rod 41 and the beam body 30 are fixed by tightening the nut 1, without complicated welding or other special processes, and only ordinary tools are needed to complete the operation, which makes the construction process simpler, reduces the requirements for the professional skills of the construction personnel, and also shortens the installation time, which can speed up the progress of the entire reinforcement project.

[0055] In addition, the sizes of screen walls of different ancient buildings are different, and the shapes of the backs of screen walls of different ancient buildings may be irregular. By sliding the mounting rod 41 in the second groove 300, the support plate 40 can flexibly adjust its position to better fit the curved or uneven surface of the back of the screen wall. This feature enables the reinforcement device to adapt to a variety of different forms of screen walls, thereby enhancing the versatility and adaptability of the device.

[0056] During the installation process, construction workers can fine-tune the position and support depth of the support plate 40 by loosening or tightening nut 1 according to the actual stress conditions of the screen wall, thereby adjusting the supporting strength of the support plate 40 on the back of the screen wall, ensuring that each support plate can effectively share the weight of the screen wall and optimize the overall reinforcement effect.

[0057] Preferably, Figure 6 As shown, the mounting rod 41 is provided with a reinforcing rib 42, which is used to support the support plate 40. The reinforcing rib 42 can increase the connection rigidity between the support plate 40 and the mounting rod 41, and effectively disperse the pressure from the screen wall borne by the support plate 40. When the weight of the screen wall or the external force applied to the support plate 40, the reinforcing rib 42 can assist the mounting rod 41 to share the load, so that the support plate 40 can significantly improve the bearing capacity without increasing its own thickness or weight, thereby more firmly supporting the screen wall and ensuring the reinforcement effect. In addition, during the long-term use of the reinforcement device, the support plate 40 is continuously subjected to pressure and is prone to deformation. The presence of the reinforcing rib 42 limits the deformation trend of the support plate 40 when subjected to force, maintains its shape stability, maintains effective support for the screen wall, and extends the service life of the support plate 40. The reinforcing rib 42 changes the stress distribution state at the connection between the support plate 40 and the mounting rod 41. In the absence of the reinforcing rib 42, the stress may be concentrated near the contact point between the mounting rod 41 and the support plate 40, which may easily cause premature damage to the area. The provision of the reinforcing ribs 42 enables the stress to be more evenly diffused throughout the entire connection area, thereby reducing stress concentration, improving the overall mechanical properties of the structure, and reducing the risk of structural failure caused by stress concentration.

[0058] Preferably, Figure 6 As shown, the reinforcing rib 42 includes a collar 421, a plurality of ribs 422 and a second fastening nut 423. The collar 421 is sleeved on the mounting rod 41, and a plurality of ribs 422 are arranged on the outer wall of the collar 421 at intervals along the circumferential direction of the central axis of the collar 421. The second fastening nut 423 is sleeved on the mounting rod 41 and is located on the side of the collar 421 away from the mounting rod 41, and is used to limit the collar 421 so that the ribs 422 are close to the support plate 40. In this embodiment, there are four ribs 422, and the four ribs 422 form a cross structure.

[0059] A plurality of ribs 422 are arranged at intervals along the circumferential direction of the central axis of the collar 41. This arrangement enables the support plate 40 to obtain uniform support force in all directions. When the pressure of the screen wall acts on the support plate 40, the ribs 422 can disperse the pressure from different angles to prevent the support plate 40 from being deformed or damaged due to uneven local force, thereby effectively improving the bearing capacity and stability of the support plate 40. In actual use, the support plate 40 can be further reinforced by rotating the collar 421 so that the reinforcing ribs 42 are located at different positions on the support plate 40. The support plate 40 can be selectively adjusted according to the actual repair position, and after the position of the reinforcing ribs 42 is adjusted, it can be tightened by the nut 2 423.

[0060] A reinforcement method for repairing an ancient building wall, using the reinforcement device of this embodiment for reinforcement, comprises: Figure 7 As shown, the base 11 is buried underground on both sides of the screen wall, the column 12 is arranged close to both sides of the screen wall, the clamping plates 23 are used to clamp the two sides of the screen wall, and the support plate 40 is used to support the back of the screen wall.

[0061] Specifically: 1. Installation of the base 11 and the column 12 Embed the base 11: dig foundation pits on the ground on both sides of the screen wall, and embed the concrete base 11 in advance to ensure that the base 11 is level and stable to resist ground settlement.

[0062] Install the column 12: fix the prefabricated concrete column 12 on the base 11, and the column 12 is close to both sides of the screen wall. The inside of the column 12 is an I-beam 121 wrapped with a concrete layer 122, and the groove 120 faces outward.

[0063] Limit block inspection: Confirm that the limit block 1200 in the slot 120 has been prefabricated to prevent the subsequently installed base block 21 from falling off.

[0064] 2. Adjustment and fixation of clamping part 2 Sliding base block 21: Slide the base block 21 of the clamping part 2 along the groove 120 of the column 12 to the target height, select the corresponding screw hole 3, and fix the base block 21 to the flange of the I-beam with bolts.

[0065] Install the clamping plate 23: Fix the L-shaped mounting plate 22 on the base block 21, and adjust the position of the clamping plate 23 by means of the adjusting piece 24. According to the thickness of the screen wall, add or remove gaskets between the extension plate 241 and the clamping plate 23, align the first and second screw holes, and tighten them with the fixing screws 242 and nuts to ensure that the clamping plate 23 fits tightly against both sides of the screen wall.

[0066] 3. Installation of beam 3 and support 4 Install the beams: install the beams 30 between the corresponding mounting plates of the columns 12 on both sides of the back of the screen wall, and connect them horizontally to form a supporting frame.

[0067] Fix the support plate 40: slide the mounting rod 41 of the support plate 40 into the second beam body groove 300, adjust the position and tighten the nut 1 to fix it.

[0068] Strengthening rib reinforcement: The collar 421 is inserted into the mounting rod, the cross rib plate 422 is adjusted to be close to the back of the support plate 40, and is locked with the second fastening nut 423 to enhance the pressure resistance of the support plate 40.

[0069] 4. Overall commissioning and acceptance Check the clamping and support: make sure the clamping plate 23 is not loose, the support plate 40 is in even contact with the back of the screen wall, and fine-tune the bolts or gaskets if necessary.

[0070] Example 2 The difference from Example 1 is that: preferably, Figure 8 , Fig. 9 , Fig.10 As shown, the reinforcement device further includes a stabilizing portion 5, which is arranged between two adjacent beam bodies 30, and includes a vertical rod 51, a bonding plate 52, and four connecting rods 53. The vertical rod 51 is vertically arranged between two adjacent beam bodies 30, and its two ends are respectively fixed on the two beam bodies 30, the bonding plate 52 is fixed on the vertical rod 51, one side of the bonding plate 52 is arranged on the vertical rod 51, and the other side is bonded to the back of the screen wall for supporting the back of the screen wall, and the four connecting rods 53 are distributed in an X shape, one end of which is fixed to the bonding plate 52, and the other end is fixed to the beam body 30.

[0071] The vertical rod 51 is vertically arranged between two adjacent beams 30, and the two ends are fixed on the beams, which connects the originally relatively independent beams 30 into a more stable overall frame structure. This connection method greatly enhances the cooperative working ability between the beams 30, so that the beams 30 can jointly resist deformation and displacement when bearing the pressure from the screen wall and the external environment, effectively reducing the shaking or tilting of the beams 30 due to uneven force, thereby improving the stability of the entire reinforcement device.

[0072] Four connecting rods 53 are arranged in an X shape, one end of which is fixed on the bonding plate 52, and the other end is fixed on the beam body 30. This cross structure can provide support and restraint for the bonding plate 52 and the beam body 30 from multiple angles. When the screen wall is subjected to external forces in different directions, the X-shaped connecting rods 53 can disperse the forces to each beam body 30 and the vertical rod 51, avoiding excessive local forces, and further enhancing the stability and reliability of the entire stabilizing part and the reinforcement device.

[0073] The laminating plate 52 is fixed on the vertical rod 51, and one side of the laminating plate is in contact with the back of the screen wall, so as to directly provide support to the back of the screen wall. The laminating plate 52 is in contact with the screen wall over a large area, so that the supporting force can be evenly distributed on the back of the screen wall, reducing the pressure on the local part of the screen wall and avoiding damage to the screen wall due to stress concentration. At the same time, the laminating plate 52 can also play a buffering role, reducing the impact of external vibration and impact force on the screen wall, and better protecting the integrity of the screen wall.

[0074] The vertical rods 51, the laminating plates 52 and the connecting rods 53 of the stabilizing part 5 cooperate with each other to form a coordinated support system. The laminating plates 52 directly support the screen wall, the vertical rods 51 transmit the supporting force of the laminating plates 52 to the beam body 30, and the X-shaped connecting rods 53 further strengthen the transmission and dispersion of this force. This coordinated working mode allows the pressure on the screen wall to be more evenly dispersed to the entire reinforcement device, thereby improving the supporting effect on the screen wall and enhancing the stability and safety of the screen wall.

[0075] The setting of the stabilizing part 5 changes the stress state of the reinforcement device, so that the force originally concentrated on the beam body 30 and the support plate 40 can be distributed more reasonably. The presence of the vertical rod 51 and the connecting rod 53 increases the redundancy of the structure, and improves the bearing capacity and anti-deformation ability of the structure. When facing complex stress conditions, the stabilizing part 5 can better coordinate the forces between the various components, avoid weak links, and ensure the safety and reliability of the reinforcement device during long-term use. The entire reinforcement device is formed into an organic whole through the stabilizing part 5. This integrity not only improves the stability and bearing capacity of the structure, but also enhances the seismic performance of the structure. When natural disasters such as earthquakes occur, the stabilizing part 5 can effectively disperse the seismic force to various components, reduce the degree of damage to the structure, and protect the safety of the screen wall of the ancient building.
