Description
Technical Field
[0001] This invention relates to the field of wall reinforcement technology, and in particular to a reinforcement device and construction method for protecting brick masonry walls. Background Technology
[0002] Brick walls are widely used in the boundary protection structures of residential areas, factories, schools, gardens and various other sites due to their convenient material availability and simple construction. Existing brick walls are usually constructed by combining bricks and mortar to form an integral structure. Some walls are also combined with foundations, structural columns or capping to improve stability. In actual projects, when the wall develops local cracks, tilts or decreases in load-bearing stability after construction, it is usually repaired and reinforced by adding supports, partially dismantling and rebuilding, encasing it in concrete and rebuilding it, or creating through holes in the wall to insert steel bars, thereby restoring its basic enclosure and protection functions.
[0003] However, existing brick walls are prone to cracking, tilting, and even collapse during long-term use due to factors such as unstable foundations, foundation settlement, and external impacts. For damaged walls, current reinforcement methods mainly rely on simple structural supports or localized repairs. These methods often suffer from insufficient connection with the original wall structure, poor overall load-bearing capacity, and inadequate resistance to continuous deformation. Consequently, the stability of the reinforced wall remains limited, and it still faces the risk of further damage or even collapse during subsequent use. Therefore, it is necessary to propose a protective reinforcement device and construction method for brick walls to improve the stability and reliability of the reinforced structure. Summary of the Invention
[0004] In view of this, the purpose of this invention is to propose a reinforcement device and construction method for protecting brick masonry walls, so as to solve the problem that existing methods mainly rely on simple structural auxiliary support or local repairs, which leads to the risk of further damage or even instability and collapse of the reinforced walls during subsequent use, resulting in insufficient stability and reliability.
[0005] To achieve the above objectives, the present invention provides a reinforcement device for protecting brick masonry walls, including a foundation buried in the soil layer, a brick masonry wall built on top of the foundation by stacking bricks, and an anti-sinking component provided between the top of the foundation and the two sides of the brick masonry wall for forming a lateral tie, diagonal support and bottom anchoring cooperation for the bottom of the brick masonry wall.
[0006] The anti-sinking component includes multiple first steel bars, which are inserted between the two sides of the brick wall near the top of the foundation. The two ends of the multiple first steel bars are respectively fixed with reinforcing steel bars by steel wire. The reinforcing steel bars are in the shape of a "V" structure, and the bottom end of the reinforcing steel bars abuts against the top of the foundation.
[0007] The outer walls on both sides of the brick wall are provided with reinforcement components for forming a planar constraint on the brick wall and forming a through-wall clamping cooperation with the brick wall. The reinforcement components include a grid-type steel frame set on both sides of the brick wall. Each grid-type steel frame includes three vertically arranged vertical steel plates and three horizontally arranged horizontal steel plates. The three vertical steel plates and the three horizontal steel plates are staggered to form a grid-type steel frame structure with multiple nodes connected on the outside of the brick wall.
[0008] Preferably, two second reinforcing bars are laterally fixedly connected between the sidewalls of the plurality of reinforcing bars. The two second reinforcing bars are spaced apart along the height direction to laterally connect the plurality of reinforcing bars and maintain the spacing between the plurality of reinforcing bars, so that the plurality of reinforcing bars form an integral support structure distributed along the length direction of the brick wall. A first concrete layer is poured on both sides of the top of the foundation near the bottom of the brick wall. The first concrete layer is used to cover and anchor at least part of the structure of the plurality of first reinforcing bars, reinforcing bars and second reinforcing bars, and to connect and cooperate the anti-sinking component with the top of the foundation and the bottom of the brick wall.
[0009] Preferably, the vertical steel plate and the horizontal steel plate have a first fastening part and a second fastening part respectively on their opposite surfaces. The first fastening part and the second fastening part fasten each other in the assembled state to form an abutment fit, which is used to pre-position the vertical steel plate and the horizontal steel plate at the node position, and to make the horizontal steel plate support the vertical steel plate when subjected to vertical force, and to make the vertical steel plate laterally support the horizontal steel plate when subjected to lateral force.
[0010] Preferably, the sidewalls of the vertical and horizontal steel plates are provided with through holes near the middle of the first fastening part, and bolts are provided between the corresponding through holes. The bolts pass through the sidewalls of the brick wall and the through holes on the vertical and horizontal steel plates, and are tightened by nuts to limit the relative displacement of the vertical and horizontal steel plates at the nodes, and to make the grid-type steel frame structure on both sides of the brick wall form a through-wall tie with the brick wall.
[0011] Preferably, the outer wall of the assembled vertical and horizontal steel plates is provided with fastening reinforcing bars. The fastening reinforcing bars are in the shape of a "U" shape. The two ends of the fastening reinforcing bars are respectively inserted into through holes opened in the outer wall of the brick wall by drilling equipment. The middle part of the fastening reinforcing bars abuts against the horizontal steel plate assembled on one side of the brick wall. The two ends of the fastening reinforcing bars are bent by external force to form bends. The bends abut against the horizontal steel plate assembled on the other side of the brick wall, so that an additional through-wall clamping connection is formed between the horizontal steel plates on both sides of the brick wall. A second concrete layer is poured on both side walls of the brick wall. The second concrete layer covers the structure of the vertical steel plates, horizontal steel plates and fastening reinforcing bars, so that the brick wall and the reinforcement components form an encapsulated connection structure.
[0012] Preferably, two sets of covering plates are provided on both sides of the brick wall. The covering plates are in the shape of an "L" and the two sets of covering plates are respectively arranged in the corner area of the end of the brick wall to cover the four outer corners of the brick wall. The side walls of the two sets of covering plates are respectively fixedly connected to connecting plates. The connecting plates are used to maintain the relative positional relationship and corner covering state between the covering plates in the same group, and serve as the connection part between the covering plates and adjacent components.
[0013] Preferably, a clamping plate is fixedly connected to the side wall of the covering plate, and a slot is fixedly connected to one end of the horizontal steel plate near the covering plate. The slot is snapped onto the side wall of the clamping plate to limit the relative displacement of the horizontal steel plate near the end of the brick wall and to form an end-limiting connection between the horizontal steel plate and the covering plate.
[0014] Preferably, the cross-sectional shape of the vertical steel plate and the horizontal steel plate is U-shaped, so as to form a clearance space in the thickness direction of the vertical steel plate and the horizontal steel plate for setting the first fastening part and the second fastening part, and to form a limiting fit along the cross-sectional direction between the vertical steel plate and the horizontal steel plate in the node assembly state.
[0015] Preferably, the first concrete layer covers the lower part of the plurality of reinforcing bars and at least part of the second reinforcing bars, and the first concrete layer forms a wedge-shaped, sloping, or shoulder-shaped structure to form an abutment and support with the outer side of the bottom of the brick wall.
[0016] Preferably, a construction method for protecting brick masonry walls utilizes the reinforcement device for protecting brick masonry walls described in any of the above claims, characterized by comprising the following steps:
[0017] S1. Excavate the soil around the brick wall to expose the construction area on both sides of the foundation top and the bottom of the brick wall, and clean the floating dust, loose mortar and damaged parts on the surface of the brick wall.
[0018] S2. Drill multiple through holes along the length of the brick wall near the bottom, insert multiple first steel bars between the two sides of the brick wall, and then tie and fix the reinforcing steel bars at both ends of each first steel bar with steel wires so that the bottom end of the reinforcing steel bars abuts the top of the foundation. Then, use two second steel bars to connect and fix the multiple reinforcing steel bars laterally, and pour the first concrete layer on both sides of the bottom of the brick wall.
[0019] S3. Install two sets of covering plates at the corners of the brick wall, and then install vertical steel plates and horizontal steel plates on both sides of the brick wall respectively, so that the second fastening part on the horizontal steel plate is fastened to the first fastening part on the vertical steel plate, and the slot at the end of the horizontal steel plate is engaged with the card plate on the covering plate.
[0020] S4. Using the holes on the vertical and horizontal steel plates as positioning references, drill corresponding holes in the brick wall, and pass the bolts through the holes on one side of the vertical and horizontal steel plates, the brick wall, and the holes on the other side of the vertical and horizontal steel plates in sequence, and then tighten them with nuts.
[0021] S5. Place the fastening steel bar on the outside of one side of the horizontal steel plate, so that its two ends pass through the pre-set through hole in the brick wall and extend to the other side. Then apply external force to its two ends to bend it to form a bent part, so that the bent part abuts against the other side of the horizontal steel plate.
[0022] S6. Pour a second layer of concrete on both sides of the brick wall to form a covered reinforcement structure consisting of the brick wall, the grid steel frame, the reinforcing bars and the covering plate.
[0023] The beneficial effects of this invention are:
[0024] 1. The reinforcement device and construction method for protecting brick masonry walls, through the anti-sinking component, is composed of multiple first steel bars, multiple reinforcing steel bars, second steel bars, and a first concrete layer working together. The multiple first steel bars form a lateral tie to the bottom of the brick masonry wall, and the "V"-shaped reinforcing steel bars form diagonal supports on both sides of the bottom of the wall. Combined with the lateral connection of the second steel bars and the covering and anchoring effect of the first concrete layer, a relatively stable composite support structure is formed at the bottom of the wall. This can improve the stress concentration at the base of the wall and enhance the adaptability of the bottom of the wall to foundation settlement and local loosening.
[0025] 2. The reinforcement device and construction method for protecting brick masonry walls utilize a grid-type steel frame structure, through-wall connection structure, reinforcing bars, covering plates, and a second concrete layer on both sides of the brick masonry wall to form multi-point connections and overall constraints on the wall body and corner areas. The interlocking fit between the vertical and horizontal steel plates facilitates node positioning and force transfer, and also allows for rapid assembly. Bolts and reinforcing bars further enhance the clamping stability between the components on both sides and the wall. The covering plates protect weak corner areas, thereby improving the wall's ability to restrain cracking, tilting, and continuous deformation, as well as its stability and reliability, and increasing the service life of the brick masonry wall.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0040] like Figures 1 to 9 As shown, a reinforcement device for protecting a brick wall includes a foundation 1 buried in the soil. The anti-sinking component can be composed of multiple first reinforcing bars 3, multiple reinforcing bars 4, second reinforcing bars 5, and a first concrete layer 6 set on both sides of the bottom of the brick wall 2. The multiple first reinforcing bars 3 are spaced apart along the length of the brick wall 2 and pass through the two sides of the brick wall 2. They are preferably arranged near the top of the foundation 1 and near the bottom of the wall, so that the multiple first reinforcing bars 3 can penetrate the brick wall 2 laterally and form a lateral tie to the bottom area of the brick wall 2. The two ends of the multiple first reinforcing bars 3 are respectively fixed with reinforcing bars 4 by steel wire. The steel wire can be tied and fixed by conventional tie wire, which can quickly achieve a reliable connection between the first reinforcing bars 3 and the reinforcing bars 4 during construction.
[0041] The reinforcing steel bar 4 has a "V" shaped structure, with its bottom end abutting against the top of the foundation 1. Multiple reinforcing steel bars 4 can be spaced along the length of the brick wall 2 on both sides of the brick wall 2. Because the reinforcing steel bar 4 adopts a "V" shaped structure, when under stress, it can decompose the load transmitted from the bottom of the brick wall 2 into a supporting force transmitted along the two arms of the reinforcing steel bar 4, making the bottom stress more dispersed and avoiding concentrated action on a local area at the root of the wall.
[0042] On the other hand, the bottom end of the "V"-shaped structure directly abuts the top of the foundation 1, which can form a support state similar to the combination of diagonal bracing and support, expand the bottom support range, and improve the wall base's resistance to subsidence, outward roll and overturning. Two second steel bars 5 are horizontally fixedly connected between the side walls of multiple reinforcing steel bars 4. The two second steel bars 5 are preferably set at intervals along the height direction. The function of the second steel bars 5 is to horizontally connect and maintain the spacing of multiple reinforcing steel bars 4, so as to prevent each reinforcing steel bar 4 from swinging alone, spreading out or being unevenly stressed during construction and subsequent stress, so that multiple reinforcing steel bars 4 can form a relatively stable overall stress.
[0043] Meanwhile, the second reinforcing bar 5 can further improve the lateral integrity of the anti-sinking component, so that each "V"-shaped reinforcing bar 4 can bear the force together, enhancing the lifting and limiting effect on the bottom of the brick wall 2. The top of the foundation 1 is poured with a first concrete layer 6 on both sides near the bottom of the brick wall 2. The first concrete layer 6 preferably covers the lower part of multiple reinforcing bars 4 and at least part of the second reinforcing bars 5, so that the first reinforcing bar 3, reinforcing bars 4, second reinforcing bars 5 form an integrated connection with the top of the foundation 1 and the bottom of the wall. After this setting, the first concrete layer 6 can not only wrap, anchor and protect the anti-sinking component, but also expand the contact and support area between the wall base and the foundation 1, improve the bottom compressive bearing capacity, and reduce the risk of the bottom of the wall continuing to sink, crack or become unstable.
[0044] The first concrete layer 6 can form a wedge-shaped, sloping, or shoulder-shaped structure near the bottom of the wall to better match the outer bottom of the brick wall 2 and improve the bottom support effect.
[0045] The reinforcement components are installed on the outer walls of both sides of the brick wall 2 to provide overall constraint and protection for the wall area. The reinforcement components are set on the grid-type steel frame on both sides of the brick wall 2. Each side of the grid-type steel frame consists of three vertically arranged vertical steel plates 7 and three horizontally arranged horizontal steel plates 9. The three vertical steel plates 7 are arranged at intervals along the length of the brick wall 2, and the three horizontal steel plates 9 are arranged at intervals along the height of the brick wall 2. The three vertical steel plates 7 and the three horizontal steel plates 9 are staggered to form a grid-type steel frame with multiple nodes on the outside of the brick wall 2. This grid-type steel frame can cover the main stress area of the brick wall 2 and form a planar constraint on the wall. Compared with the traditional method of only adding support rods or single steel sections in some areas, it can make the wall more uniformly stressed, avoid stress concentration, and improve the overall bending, shear and lateral deformation resistance of the wall.
[0046] Both the vertical steel plate 7 and the horizontal steel plate 9 have a U-shaped cross-section. With this U-shaped cross-section, under the same material conditions, compared with the ordinary flat plate structure, a higher moment of inertia and better bending stiffness can be obtained, thereby improving the stability of the vertical steel plate 7 and the horizontal steel plate 9 under compression, bending and joint stress, and making it less prone to local deformation or buckling. At the same time, the U-shaped cross-section also facilitates the formation of an installation space that is compatible with the interlocking structure, making the joint assembly more stable.
[0047] The vertical steel plate 7 and the horizontal steel plate 9 have a first fastening part 8 and a second fastening part 10 respectively on their opposite surfaces. The first fastening part 8 and the second fastening part 10 fasten each other and form an abutting fit in the assembled state. The first fastening part 8 and the second fastening part 10 can be a corresponding snap-fit groove, a clearance opening or a plug-in notch structure. When the horizontal steel plate 9 is assembled, it is fastened to the first fastening part 8 of the vertical steel plate 7 through the second fastening part 10, so that the vertical steel plate 7 and the horizontal steel plate 9 first form a pre-positioning relationship that limits each other at the node position. The function of this fastening structure is: firstly, through the fastening and abutting fit, the vertical steel plate 7 and the horizontal steel plate 9 can be quickly positioned before other fasteners are installed, reducing the difficulty of on-site installation.
[0048] Secondly, when the horizontal steel plate 9 is subjected to vertical loads or wall bulging, the horizontal steel plate 9 can be supported by the vertical steel plate 7 to prevent the horizontal steel plate 9 from shifting downwards.
[0049] Third, when the vertical steel plate 7 is subjected to lateral force, the horizontal steel plate 9 can provide lateral support to the vertical steel plate 7, thereby forming a two-way force support relationship at the node, which improves the overall rigidity and stability of the entire grid-type steel frame.
[0050] Fourth, this type of interlocking connection combines surface contact with node support, which helps to disperse local stress at the nodes and improve the stress reliability of the connection.
[0051] To further limit the relative displacement between the vertical steel plate 7 and the horizontal steel plate 9, through holes 11 are respectively provided on the side walls of the vertical steel plate 7 and the horizontal steel plate 9 near the middle of the first fastening part 8. After the vertical steel plate 7 and the horizontal steel plate 9 are assembled, bolts 12 are provided between the corresponding through holes 11. The bolts 12 pass through the side walls of the brick wall 2 and the through holes 11 on the vertical steel plate 7 and the horizontal steel plate 9, and are locked with nuts. With this arrangement, on the one hand, the bolts 12 can connect the grid-type steel frame on both sides of the brick wall 2 with the brick wall 2 body through the wall, so that the brick wall 2 and the reinforcement components on both sides form an integral whole to share the force.
[0052] On the other hand, bolt 12 can also lock the fastening relationship at the joint of vertical steel plate 7 and horizontal steel plate 9 for a second time, preventing the vertical steel plate 7 and horizontal steel plate 9 from loosening, shifting or separating under long-term load, vibration or continued deformation of the wall, thereby improving the long-term stability of the reinforced structure.
[0053] The outer wall after the vertical steel plate 7 and horizontal steel plate 9 are assembled is also provided with fastening steel bars 13. The fastening steel bars 13 have a "U" shaped structure. The two ends of the fastening steel bars 13 are respectively inserted into through holes opened in the outer wall of the brick wall 2 by drilling equipment. The middle part of the fastening steel bars 13 abuts against the horizontal steel plate 9 assembled on one side of the brick wall 2. After passing through the brick wall 2, the two ends of the fastening steel bars 13 are bent inward by external force to form a bend 14. The bend 14 abuts against the horizontal steel plate 9 assembled on the other side of the brick wall 2. Through the above structure, the fastening steel bars 13 can form an additional through-wall clamp connection between the horizontal steel plates 9 on both sides of the brick wall 2.
[0054] The middle section applies a pressing force to one side of the horizontal steel plate 9, and the bent sections 14 formed at both ends apply a reverse limiting force to the other side of the horizontal steel plate 9. This allows the grid-type steel frame on both sides of the brick wall 2 to form a clamping and fastening connection. Compared with only using bolts 12 for node locking, the fastening steel bars 13 can provide additional overall constraint force and anti-loosening ability. It is especially suitable for secondary tightening of the brick wall 2 with existing cracks and local loosening. It is beneficial to suppress the wall from continuing to crack and bulge outward deformation, and improve the synergistic force-bearing effect between the steel frame on both sides and the wall.
[0055] To improve the protection of the corners of the wall, two sets of covering plates 15 are installed on both sides of the brick wall 2. The covering plates 15 are in the shape of an "L". The two sets of covering plates 15 are respectively arranged in the corner area at the end of the brick wall 2 to form a corner protection for the four outer corners of the brick wall 2. The corners of the wall are usually the parts in the brick structure that are prone to stress concentration, corner chipping, cracking and local collapse. By setting "L" shaped covering plates 15 at the corners, the corners can be rigidly protected and edge restrained, reducing the damage caused by direct exposure of the corners to impact, wind pressure or construction disturbance.
[0056] Two sets of cladding plates 15 are respectively fixedly connected to the side walls of the two sets of cladding plates 15. The connecting plates 16 can be welded to the corresponding cladding plates 15 as a whole, or fixedly connected by means of screwing, riveting, etc. The main function of the connecting plates 16 is to improve the overall rigidity and structural stability of the cladding plates 15 themselves, so that the cladding plates 15 in the same group can maintain a stable corner wrapping state after installation, and prevent the cladding plates 15 from opening, shifting or shaking during subsequent installation of horizontal steel plates 9, vertical steel plates 7 and pouring concrete. At the same time, the connecting plates 16 can also serve as auxiliary force-bearing connection parts between the cladding plates 15 and other components, so as to facilitate the distribution and transmission of external forces on the corner to adjacent components, thereby improving the overall impact resistance and deformation resistance of the corner area.
[0057] A clamping plate 17 is fixedly connected to the side wall of the covering plate 15, and a slot 18 is fixedly connected to the end of the horizontal steel plate 9 near the covering plate 15. The slot 18 is snapped onto the side wall of the clamping plate 17. Through the snapping cooperation between the clamping plate 17 and the slot 18, the horizontal steel plate 9 can form a reliable limiting connection with the covering plate 15 after it is installed in place. With this setting, on the one hand, the displacement of the horizontal steel plate 9 near the end of the wall can be limited, making the end of the grid steel frame more stable.
[0058] On the other hand, the horizontal steel plate 9 and the covering plate 15 can be connected as a whole, so that the covering plate 15 can not only play a corner protection role, but also participate in the overall reinforcement and load-bearing system, further enhancing the overall stability of the wall end and corner area.
[0059] In addition, a second concrete layer 19 is poured on both sides of the brick wall 2. The second concrete layer 19 is preferably poured in the enclosing space formed by the outer wall of the brick wall 2 and the reinforcing components, and covers at least part of the structure of the vertical steel plate 7, the horizontal steel plate 9 and the fastening steel bar 13. The setting of the second concrete layer 19 can further bond and anchor the brick wall 2 and the external reinforcing components into a whole, and improve the cooperative stress state between the surface of the brick wall 2 and the steel frame.
[0060] On the other hand, the second concrete layer 19 can also protect the reinforced components, reduce the damage caused by rainwater erosion, weathering or collision to the steel components directly exposed to the external environment, thereby extending the service life of the reinforced structure. The second concrete layer 19 can be formed by ordinary concrete, fine stone concrete, repair mortar or casting materials with certain micro-expansion properties to improve the bonding effect between it and the brick wall 2 and the steel components.
[0061] Workflow: During construction, the soil around the brick wall 2 is first excavated to expose the top of the foundation 1 and the construction areas on both sides of the bottom of the brick wall 2. The surface dust, loose mortar and damaged parts of the wall are cleaned. Then, multiple through holes are drilled along the length of the brick wall 2 near the bottom, and multiple first steel bars 3 are inserted between the two sides of the brick wall 2. Then, the two ends of each first steel bar 3 are tied with steel wire to fix the reinforcing steel bars 4, so that the bottom end of the reinforcing steel bars 4 is stably abutted against the top of the foundation 1, thereby forming multiple "V" shaped support structures on both sides of the bottom of the wall. Then, two second steel bars 5 are used to connect and fix the multiple reinforcing steel bars 4 laterally, so that the multiple reinforcing steel bars 4 maintain a stable spacing and form an integral load-bearing structure. After that, the first concrete layer 6 is poured on both sides of the bottom of the brick wall 2 to anchor and cover the lower part of the first steel bars 3, the reinforcing steel bars 4 and the second steel bars 5.
[0062] After the bottom anti-sinking component is formed, two sets of covering plates 15 are installed at the corners of the brick wall 2, so that the covering plates 15 cover and protect the four corners of the brick wall 2; then three vertical steel plates 7 and three horizontal steel plates 9 are installed on both sides of the brick wall 2, so that the second fastening part 10 on the horizontal steel plate 9 is fastened to the first fastening part 8 on the side wall of the vertical steel plate 7. With the mutual fastening and abutment of the first fastening part 8 and the second fastening part 10, the vertical steel plate 7 and the horizontal steel plate 9 form a stable node pre-position during the installation stage, and can support each other when under force, thus forming a grid-type steel frame.
[0063] Then, using the through holes 11 on the vertical steel plate 7 and the horizontal steel plate 9 as positioning references, corresponding holes are drilled in the brick wall 2, and the bolts 12 are passed through the through holes 11 on one side of the vertical steel plate 7 and the horizontal steel plate 9, the brick wall 2, and the through holes 11 on the other side of the vertical steel plate 7 and the horizontal steel plate 9 in sequence. Then, the bolts are tightened with nuts so that the grid-type steel frame on both sides of the brick wall 2 forms a through-wall clamping and fastening with the wall.
[0064] Next, the fastening steel bar 13 is placed on the outside of the horizontal steel plate 9 on one side, so that its two ends pass through the pre-set through holes in the brick wall 2 and extend to the other side. Then, external force is applied to both ends to bend them to form a bent part 14, so that the bent part 14 abuts against the horizontal steel plate 9 on the other side, thereby further clamping and locking the two horizontal steel plates 9 through the wall.
[0065] While installing the horizontal steel plate 9, the slot 18 at the end of the horizontal steel plate 9 is engaged with the clamping plate 17 on the covering plate 15 to achieve end-limiting connection between the horizontal steel plate 9 and the covering plate 15; after the above steel components and connectors are installed, a second concrete layer 19 is poured on both sides of the brick wall 2 to form a more stable integrated protective and reinforced structure of the brick wall 2, the grid steel frame, the fastening steel bars 13 and the covering plate 15.
[0066] After adopting the above structure and construction method, firstly, the anti-sinking component formed by the first steel bar 3, the reinforcing steel bar 4, the second steel bar 5 and the first concrete layer 6 can form a support system at the bottom of the brick wall 2 that combines horizontal tie, diagonal support and concrete covering and anchoring, to support and widen the support at the base of the wall, and reduce the continued damage to the wall caused by unstable foundation or local settlement.
[0067] Secondly, the grid-type steel frame and node locking structure formed by the vertical steel plate 7, horizontal steel plate 9, first fastening part 8, second fastening part 10, through hole 11 and bolt 12 can form multi-node, multi-directional planar constraints on both sides of the brick wall 2, thereby improving the overall bending resistance, shear resistance and toppling resistance of the wall.
[0068] Third, the additional through-wall clamping structure formed by fastening the reinforcing bars 13 and the bent part 14 can further improve the clamping reliability between the two side reinforcement components and enhance the restraint effect on the existing cracked wall.
[0069] Fourth, the corner covering and end limiting structure formed by the covering plate 15, connecting plate 16, clamping plate 17 and clamping groove 18 can provide key protection for the weak area at the corner of the brick wall 2, and make the corner covering structure and the horizontal steel plate 9 work together to bear the force.
[0070] Fifth, by covering and integrating the external reinforcing components with a second concrete layer 19, the overall integrity and durability of the structure can be further improved. Therefore, this application not only effectively protects and reinforces existing brick walls, but also achieves multiple effects such as preventing bottom subsidence, preventing wall cracking, and preventing overall collapse. Compared with traditional methods that rely solely on local support, partial dismantling and reconstruction, or reinforcement with a single steel component, this approach offers higher overall stability, better synergistic stress distribution, and a lower risk of subsequent damage.

Then, use two second steel bars 5 to connect and fix the multiple reinforcing steel bars 4 laterally, and pour the first concrete layer 6 on both sides of the bottom of the brick wall 2.
[0074] S3. Install two sets of covering plates 15 at the corner of the brick wall 2, and then install vertical steel plates 7 and horizontal steel plates 9 on both sides of the brick wall 2 respectively, so that the second fastening part 10 on the horizontal steel plate 9 is fastened to the first fastening part 8 on the vertical steel plate 7, and the slot 18 at the end of the horizontal steel plate 9 is fastened to the card plate 17 on the covering plate 15.
[0075] S4. Using the through holes 11 on the vertical steel plate 7 and the horizontal steel plate 9 as positioning references, drill corresponding holes in the brick wall 2, and pass the bolts 12 through the through holes 11 on one side of the vertical steel plate 7 and the horizontal steel plate 9, the brick wall 2, and the through holes 11 on the other side of the vertical steel plate 7 and the horizontal steel plate 9 in sequence, and then tighten them with nuts.
[0076] S5. Set the fastening steel bar 13 on the outside of the horizontal steel plate 9 on one side, so that its two ends pass through the pre-set through hole in the brick wall 2 and extend to the other side. Then apply external force to its two ends to bend it to form a bent part 14, so that the bent part 14 abuts against the horizontal steel plate 9 on the other side.
[0077] S6. Pour a second concrete layer 19 on both sides of the brick wall 2 to form a covered reinforcement structure consisting of the brick wall 2, the grid steel frame, the reinforcing steel bars 13 and the covering plate 15.
