Description

Technical Field

[0001] This invention relates to the field of building engineering, specifically to energy-saving renovation technology for masonry exterior walls. Background Technology

[0002] Masonry exterior walls are a crucial structural element of buildings, bearing the brunt of natural disasters such as earthquakes and external loads. In older buildings, due to years of neglect, exterior walls may crack or loosen, significantly reducing their earthquake resistance. In the event of an earthquake or other natural disaster, this poses a serious threat to life and property. Therefore, reinforcing and renovating masonry exterior walls with earthquake-prone features is essential. Furthermore, building exterior walls are a significant factor affecting a building's energy efficiency. Masonry exterior walls have a high thermal conductivity; without insulation, a large amount of heat will dissipate from the building's interior, leading to energy waste.

[0003] Seismic reinforcement and energy-saving renovation of masonry exterior walls involve many common tasks, such as cleaning and pretreatment of the exterior wall surface, laying and fixing of the insulation layer, and reinforcement of the exterior wall.

[0004] Currently, many existing buildings fail to meet both seismic safety and energy-saving requirements. However, the reinforcement and energy-saving renovation of existing building exterior walls are often carried out separately, requiring separate surveys, designs, and construction, resulting in low efficiency. For example, technically, both seismic reinforcement and energy-saving renovation require the partial or complete removal of the original base plaster and decorative layers. However, if traditional, non-energy-efficient plastering is used during the post-reinforcement plastering and decoration work, the base plaster and decorative layers from the initial seismic reinforcement project must be removed during the later energy-saving renovation. This approach fails to meet the energy-saving and emission-reduction requirements of building construction. Therefore, it is necessary to organically combine the two processes to achieve integrated design and construction of seismic reinforcement and energy-saving renovation for masonry exterior walls.

[0005] Furthermore, existing seismic reinforcement methods for masonry exterior walls often employ cast-in-place construction. Cast-in-place concrete requires time to dry and harden, disrupting residents' lives and work during construction. Once completed, the modified sections are difficult to remove or adjust, hindering subsequent building maintenance and renovations. Moreover, reinforced buildings may deform, causing inconvenience to interior decoration and equipment use.

[0006] Therefore, it is evident that how to achieve integrated reinforcement and energy-saving renovation of masonry exterior walls is an urgent problem to be solved in this field, and it also has important practical significance and broad application prospects. Summary of the Invention

[0007] To address the problems existing in current seismic reinforcement construction schemes for masonry exterior walls, the present invention aims to provide an integrated energy-saving renovation method for masonry exterior wall reinforcement. This method is based on anti-pull-out insulation nails and modular technology that eliminates the need for exposed reinforcement, thereby achieving integrated seismic reinforcement and energy-saving renovation of masonry exterior walls. It is convenient, fast, safe, and reliable, and can effectively overcome the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides an integrated energy-saving renovation method for strengthening masonry exterior walls.

[0009] Modular insulation wall panels are constructed, and the constructed modular insulation wall panels have a reinforcement-free structure;

[0010] Modular wall panels are spliced ​​and installed along the outer surface of the original masonry exterior wall. The non-reinforced structures on the two adjacent modular wall panels are connected to each other, and grout is poured at the connection point to fill the two non-reinforced structures and achieve a solid connection.

[0011] The modular wall panels are fixed to the original masonry exterior wall by inserting pull-out insulation nails.

[0012] In some embodiments of the present invention, the method includes the step of pre-setting insulation nail holes at the positions of the insulation nails to be reinforced on the surface of the modular insulation wall panel and the original masonry exterior wall that needs to be reinforced.

[0013] In some embodiments of the present invention, the method involves injecting high-performance mortar or concrete after the anti-pull-out insulation nails have been inserted.

[0014] In some embodiments of the present invention, the method further includes a step of filling the joints between modular wall panels during splicing.

[0015] In some embodiments of the present invention, the method involves arranging fiberglass mesh at the splicing joints between modular wall panels and applying high-performance concrete.

[0016] In some embodiments of the present invention, the method is used to fill and seal the joint between the modular wall panel and the original masonry exterior wall surface.

[0017] In some embodiments of the present invention, the modular insulated wall panel is composed of a composite material consisting of insulation material and high-performance concrete.

[0018] In some embodiments of the present invention, the modular thermal insulation wall panel has multiple holes along its sides, and each hole is fitted with a steel bar connection assembly of adjustable length, forming a rebar-free structure.

[0019] In some embodiments of the present invention, the length-adjustable rebar connection assembly is composed of an extended rebar and a rebar-free controller.

[0020] In some embodiments of the present invention, the edges of the modular thermal insulation wall panel are provided with tongue and groove joints.

[0021] The integrated energy-saving renovation solution for masonry exterior walls provided by this invention effectively achieves the reinforcement and energy-saving renovation of masonry exterior walls based on modular insulation wall panels and anti-pull-out insulation nails as connecting keys. Furthermore, the design and manufacturing of modular wall panels can greatly reduce construction time and cost, while also improving construction safety and efficiency. This invention can meet the requirements of modern buildings for building safety, energy conservation and environmental protection.

[0022] This invention innovatively integrates seismic reinforcement and energy-saving renovation. The two technologies are mutually supportive and complementary, which not only avoids duplication of work, reduces construction preparation and procedures, and saves manpower and resources, but also improves the quality of technical renovation, saves money, and accelerates the progress of technical renovation.

[0023] The integrated energy-saving renovation solution for masonry exterior walls provided by this invention has the following advantages compared to existing technologies:

[0024] 1. Enhanced Reinforcement Performance: By using anti-pull-out insulation nails to firmly connect modular wall panels to the masonry exterior wall, the load-bearing capacity and wind pressure resistance of the masonry exterior wall are greatly improved. The reinforced wall can better withstand the effects of external forces, improving the safety and stability of the building structure.

[0025] 2. Improved construction efficiency: The design and fabrication of modular wall panels without exposed reinforcement reduces on-site construction time and process complexity. The wall panels can be prefabricated and then easily installed on-site, significantly shortening the reinforcement and renovation time and reducing labor and material costs during construction.

[0026] 3. Energy saving and environmental protection: Modular wall panels are made of thermal insulation materials and high-performance concrete (such as UHPC) composite materials. In addition to reinforcement, they also have good thermal insulation performance, effectively isolating heat conduction and improving the building's energy efficiency. The joint treatment between the wall panels and the wall also effectively prevents heat loss and water penetration, improving the wall's thermal insulation and waterproofing performance, and reducing energy consumption and maintenance costs.

[0027] 4. Convenient maintenance: Modular wall panels are relatively easy to install and remove. If the wall needs to be maintained or replaced, the wall panel can be easily removed for operation without damaging the entire wall. Attached Figure Description

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0045] To address the problems existing in current seismic reinforcement schemes for masonry exterior walls, this invention combines the technical requirements and characteristics of seismic reinforcement and energy-saving renovation projects for masonry exterior walls, and provides an integrated method for the reinforcement and energy-saving renovation of masonry exterior walls. Based on the combination of pull-out insulation nails and modular insulation wall panels that do not require exposed reinforcement, this method effectively achieves the reinforcement and energy-saving renovation of masonry exterior walls, and effectively improves the seismic performance of the reinforced components.

[0046] This solution involves pre-embedding anti-pull-out insulation nails at key locations on the masonry exterior wall, allowing modular wall panels to be tightly connected to the masonry exterior wall via these nails, thus achieving reinforcement and renovation of the masonry exterior wall.

[0047] The use of anti-pull-out insulation nails for reinforcement can increase the load-bearing capacity and stability of masonry walls to a certain extent, improve their seismic resistance, and integrate the steel structure with the masonry walls to further enhance the overall seismic performance of the building. In addition, anti-pull-out insulation nails can increase the wind pressure resistance of the masonry exterior walls, effectively preventing them from being blown down by strong winds. Simultaneously, anti-pull-out insulation nails can reduce the heat transfer coefficient of the masonry exterior walls, minimizing heat loss and thus contributing to energy conservation.

[0048] Modular wall panels are made of composite materials of thermal insulation materials and high-performance concrete (such as UHPC), combining reinforcement, energy-saving insulation, and other properties. Furthermore, the modular reinforced wall panels employ a non-exposed reinforcement design, allowing reinforcing bars to extend bidirectionally along each panel for easy connection to surrounding components. Tongue-and-groove joints can also be incorporated at the edges of the wall panels to further enhance their connectivity.

[0049] The implementation process of the present invention will be described in detail below.

[0050] The present invention is based on modular thermal insulation wall panels and pull-out resistant thermal insulation nails. Here, we will first explain the specific composition of the modular thermal insulation wall panels and pull-out resistant thermal insulation nails in the present invention.

[0051] The modular insulation wall panels in this solution are specifically modular reinforced energy-saving integrated wall panels, which will be referred to as "modular wall panels" for ease of description.

[0052] This modular wall panel is made of thermal insulation materials and high-performance concrete (such as UHPC) composite materials, and has good reinforcement, energy-saving insulation, fire resistance, and sound insulation properties.

[0053] Specifically, the composite material used to prepare the modular wall panels consists of a high-strength substrate and an insulation material. The high-strength substrate can be high-performance concrete, glass fiber reinforced concrete (GRC), or fiberglass, etc. These substrates provide structural support and strength for the wall panels. The insulation material can be a low-thermal-conductivity material (e.g., <0.05 W / (m·K)) such as polystyrene board, polyurethane foam, polystyrene (EPS), extruded polystyrene (XPS), expanded perlite, aerogel, or mineral wool, used to provide the wall panels with thermal insulation performance.

[0054] When using this composite material to prepare modular wall panels, a modular design can be adopted, and standard-sized modules can be prefabricated for easy transportation and installation.

[0055] See Figure 1 and Figure 2 The modular wall panel 1 in this invention adopts a non-reinforcing bar design, allowing reinforcing bars to extend bidirectionally along the panel, facilitating connection with surrounding components.

[0056] Specifically, when constructing a non-reinforced structure, the modular wall panel 1 has multiple holes 13 opened on the side of the modular wall panel along the perimeter. The holes 13 are used to install adjustable-length steel bar connection components to form the corresponding non-reinforced structure.

[0057] The adjustable-length rebar connection assembly here consists of a rebar-free controller 4 and corresponding protruding rebars 2 and 3. The protruding rebars are placed in the duct 13 through the rebar-free controller 4, which can control the state of the protruding rebars extending out of the duct 13, thereby achieving adjustable protrusion length of the rebars relative to the modular wall panel 1.

[0058] The specific composition of the non-extruding rebar controller 4, and its connection and cooperation structure with the corresponding protruding rebar, are not limited here, as long as they can control the protruding state of the protruding rebar relative to the duct 13 and are easy to operate.

[0059] The specific number of holes 13 opened on the side of the modular wall panel and the distribution of multiple holes are not limited here. They can be determined according to actual needs, as long as the design requirements are met.

[0060] Furthermore, the specific structural form of the holes 13 opened on the side of the modular wall panel is not limited here and can be determined according to actual needs, as long as it can effectively cooperate with the installation of the non-extrusion rebar controller and the corresponding protruding rebar. For example, in non-assembly connection (such as transportation), the non-extrusion rebar controller 4 can retract all the protruding rebars connected to it into the hole, which facilitates transportation and storage; in assembly connection, the non-extrusion rebar controller 4 can push all the protruding rebars connected to it out of the hole, and the extension length of the protruding rebars can be adjusted according to actual needs.

[0061] Furthermore, the holes on each modular wall panel 1 are preferentially distributed accordingly, so that when the modular wall panels 1 are assembled and connected, the corresponding holes on the two modular wall panels are exactly aligned, that is, the corresponding holes on the two modular wall panels are interconnected. This allows grout to be poured along the connection part, so that the connecting components are covered by the grout and a solid connection is achieved.

[0062] Furthermore, the joints between the modular wall panels in this invention can be further enhanced with different treatment methods to improve the bonding performance, such as using a tongue-and-groove connection with embedded grooves. These methods can ensure tight joints between wall panels and avoid thermal bridging and heat transfer.

[0063] Taking the figure as an example, several channels are symmetrically arranged on both sides of the modular wall panel 1. At the same time, several horizontally extending steel bars 2 of the modular wall panel are set in each channel through the non-reinforcement controller 4 for the assembly between the modular wall panels 1. The several horizontally extending steel bars 2 of the modular wall panel on each side are evenly distributed and cover the side of the modular wall panel 1, thereby ensuring the stability of the subsequent splicing between the modular wall panels 1.

[0064] Furthermore, each end of the modular wall panel 1 has symmetrically arranged channels, and each channel is equipped with several vertically extending reinforcing bars 3 of the modular wall panel via a non-reinforcing bar controller 4. These vertically extending reinforcing bars 3 are used to connect with the ring beam reinforcing bars, and grout is poured afterward to enhance the integrity of the modular wall panel and the original wall, thereby achieving joint load-bearing. The vertically extending reinforcing bars 3 of the modular wall panel on each side are evenly distributed and cover both ends of the modular wall panel 1, thus ensuring the stability of the subsequent connection between the modular wall panel 1 and the ring beam reinforcing bars.

[0065] Additionally, depending on the requirements, the modular wall panel 1 in this invention can also be provided with a tongue and groove joint 11 at the edge of the wall panel, such as... Figure 2 As shown, this further enhances the connection and assembly performance between modular reinforced wall panels. Simultaneously, the shape and size of the modular wall panels should be compatible with the existing masonry exterior walls to facilitate replacement and installation.

[0066] Furthermore, for the modular wall panel 1, corresponding insulation nail holes 12 are reserved at the corresponding positions on it so that it can be fixed to the original masonry wall through pull-out insulation nails in the future.

[0067] Preferably, the insulation nail holes 12 are distributed in a matrix along the modular reinforced wall panel 1. The specific number depends on the size and functional requirements of the reinforced wall panel. The main function is to realize the fixed connection between the modular reinforced wall panel and the original wall, and enhance the integrity of the two.

[0068] The modular wall panel 1 constructed in this example features a structure that eliminates the need for exposed reinforcement. The modular wall panel 1 incorporates bidirectional reinforcing bars, which can extend bidirectionally along the panel, facilitating connection with surrounding components (such as structural columns, walls, ring beams, etc.). Furthermore, the panels can be spliced ​​and installed together via the reinforcing bar connection controller 4 and / or tongue-and-groove joints 11. Moreover, the modular design of this wall panel 1 facilitates manufacturing, transportation, installation, and maintenance. Module dimensions can be designed as needed, allowing for easy replacement or updates.

[0069] See Figure 8 The pull-out insulation nail 9 in this invention is specifically composed of a front part 91 and a tail part 92 that cooperate with each other. In order to improve the overall stability and insulation performance of the pull-out insulation nail 9, the front part 91 and the tail part 92 of the pull-out insulation nail 9 are made of different materials.

[0070] Specifically, the front part 91 of the pull-out insulation nail 9 is made of galvanized or stainless steel, and the rear part 92 is made of insulation material with low thermal conductivity (such as glass fiber).

[0071] The front part 91 of this pull-out insulation nail 9 is made of galvanized or stainless steel, which has good strength characteristics and can withstand the stress of the insulation layer and external loads, ensuring that the insulation layer is firmly fixed to the wall and is not easy to loosen or deform. It can also provide good corrosion resistance, resisting the erosion of the insulation nail by moisture, acid and alkali and other corrosive substances in the external environment, and ensuring a long-term stable service life.

[0072] The tail 92 of this pull-out insulation nail 9 is made of insulation material with low thermal conductivity (such as glass fiber), which can effectively reduce the phenomenon of heat conduction inside the wall by the insulation nail, reduce the thermal bridging effect, and improve the insulation performance of the wall.

[0073] The specific structural form of the anti-pull-out insulation nail 9 is not limited here and can be determined according to actual needs, as long as it can meet the design requirements.

[0074] The present invention, based on the constructed modular wall panel 1 and pull-out insulating nails 9, mainly completes the integrated energy-saving renovation of masonry exterior walls through the following steps:

[0075] Step (1), positioning and drilling:

[0076] On the surface of the original masonry exterior wall 10 that needs reinforcement (such as...) Figure 7 As shown in the diagram, drill holes at the corresponding wall panel locations for the pull-out insulation nails. When drilling, determine the depth and diameter of the holes according to specific needs, ensuring the hole depth is sufficient to accommodate the front of the pull-out insulation nail, and select an appropriate hole diameter based on the required load and fixing method.

[0077] Step (2), install the modular wall panels:

[0078] The prefabricated modular wall panels 1 are sequentially assembled onto the outer surface of the original masonry exterior wall 10 using a method that avoids exposed reinforcement and / or tongue-and-groove joints, thereby forming a single reinforced panel. Figure 3 , Figure 4 As shown.

[0079] like Figure 3 As shown, when connecting rectangular modular wall panels, they are directly assembled sequentially on the outer surface of the original masonry exterior wall. The holes on two adjacent assembled rectangular modular wall panels are connected and aligned. The protruding steel bars in all the connected holes on the two rectangular modular wall panels are controlled to extend and enter the holes of the other to form corresponding connecting components. Then, grout is poured along the connection between the two rectangular modular wall panels so that the connecting components are covered with the corresponding grout, achieving a solid connection. This process is repeated to complete the assembly and connection of all rectangular modular wall panels on the outer surface of the original masonry exterior wall.

[0080] like Figure 4 As shown, when connecting tongue-and-groove modular wall panels, they are quickly assembled sequentially on the outer surface of the original masonry exterior wall based on the tongue and groove joint. The holes on two adjacent rectangular modular wall panels are connected and aligned. The protruding steel bars in all the connected holes on the two rectangular modular wall panels are controlled to extend and enter the holes of the other to form corresponding connecting components. Then, grout is poured along the connection between the two rectangular modular wall panels so that the connecting components are covered with the corresponding grout, achieving a solid connection. This process is repeated to complete the assembly and connection of all rectangular modular wall panels on the outer surface of the original masonry exterior wall.

[0081] Step (3), install the pull-out insulation nails:

[0082] In step (2), after assembling the modular wall panels on the outer surface of the original masonry exterior wall, the pre-drilled insulation nail holes 12 on each modular wall panel correspond exactly to the holes drilled on the surface of the original masonry exterior wall in step (2). Based on this, pull-out insulation nails are inserted into the masonry exterior wall along the insulation nail holes 12 on each modular wall panel and the pre-drilled holes on the original masonry exterior wall to ensure the positioning and effective connection of the wall panels. Figure 7 As shown.

[0083] In addition, after the anti-pull insulation nails are inserted, a grouting material (such as high-performance mortar or concrete) is injected in this step to prevent air and water penetration and enhance the insulation performance of the wall.

[0084] As an example, this step involves injecting caulking material into the anti-pull-out insulation nails, and is implemented through the following steps:

[0085] a) First, select a suitable grouting material, such as UHPC cement mortar. At the same time, clean the gaps to be filled, ensuring that the surface of the gaps is clean, dry and free of debris.

[0086] b) Depending on the width and depth of the gap, necessary pretreatment measures can be taken, such as using a caulking knife or broom to remove debris, dust and old caulking material, and to ensure that the gap surface is smooth;

[0087] c) Select appropriate tools, such as syringes or caulking guns, to inject caulking material into the gaps. During the injection process, it is necessary to maintain a uniform injection speed and pressure to ensure that the caulking material fills the gaps completely.

[0088] d) After injecting the filler material, use tools such as scrapers and sealing tools to fill the gap with the filler material and ensure that the filler material is flush with the surface of the gap;

[0089] e) Perform appropriate curing work according to the requirements of the grout material; that is, wait for the grout material to cure or dry for a period of time to ensure the filling effect and strength.

[0090] This step, by injecting and filling the gaps with sealant, increases the connection strength between components, improves the stability and durability of the overall structure, and prevents water, air, dust, and other substances from entering the gaps between components, thereby improving the building's sealing performance.

[0091] Step (4), set the connection structure:

[0092] After step (3) to complete the insertion and fixing of the anti-pull-out insulation nails, a connection structure is further set between the modular wall panel 1 and the original masonry exterior wall 10.

[0093] In this step, the connection between the modular wall panel 1 and the original masonry exterior wall 10 is further filled and sealed with high-performance concrete or other joint-filling materials (such as UHPC cement mortar, micro-expansion concrete, etc.) to prevent air and water penetration, and at the same time enhance the thermal insulation performance of the wall.

[0094] As an example, this step involves filling and sealing the joint between the modular wall panel 1 and the original masonry exterior wall 10, and is specifically implemented through the following steps:

[0095] a) First, select a suitable grout material and clean the gaps to be filled, ensuring that the surface of the gaps is clean, dry and free of debris;

[0096] b) Depending on the width and depth of the gap, necessary pretreatment measures can be taken, such as using a caulking knife or broom to remove debris, dust and old caulking material, and to ensure that the gap surface is smooth;

[0097] c) Select appropriate tools, such as syringes or caulking guns, to inject caulking material into the gaps. During the injection process, it is necessary to maintain a uniform injection speed and pressure to ensure that the caulking material fills the gaps completely.

[0098] d) After injecting the filler material, use tools such as scrapers and sealing tools to fill the gap with the filler material and ensure that the filler material is flush with the surface of the gap;

[0099] e) Perform appropriate curing work according to the requirements of the grout material; that is, wait for the grout material to cure or dry for a period of time to ensure the filling effect and strength.

[0100] This step, by injecting and filling the gaps with sealant, increases the connection strength between components, improves the stability and durability of the overall structure, and prevents water, air, dust, and other substances from entering the gaps between components, thereby improving the building's sealing performance.

[0101] Step (5), treat the seams:

[0102] This step involves filling and reinforcing the joints between the modular wall panels 1 to improve the overall performance of the wall.

[0103] Specifically, this step involves reinforcing the joints between modular wall panels 1 by placing fiberglass mesh 5 at the joints and applying high-performance concrete 6. For the joints between non-reinforced, tongue-and-groove modular wall panels 1, fiberglass mesh 5 is directly placed at the joints, and high-performance concrete 6 (such as UHPC fine aggregate or micro-expansion concrete) is applied. Figure 5 and Figure 7 As shown; for the assembly joints between the tongue-and-groove modular wall panels 1 that do not require exposed reinforcement, fiberglass mesh 5 is placed at the tongue and groove, and high-performance concrete 6 (such as UHPC fine aggregate, micro-expansion concrete) is applied, as shown. Figure 6 and Figure 7 As shown.

[0104] For the connection between modular wall panel 1 and ring beam 8, this step involves drilling holes at the original ring beam location, inserting and binding the protruding reinforcing bars at the top (i.e., both ends) of modular wall panel 1, and filling the connection joint with high-performance concrete (such as UHPC or micro-expansion fine aggregate concrete).

[0105] As an example, this step of filling and sealing the joint between modular wall panel 1 and ring beam 8 is specifically achieved through the following steps:

[0106] a) Design preparation work: Based on the specific structural design requirements and load calculations, determine the location, quantity, diameter and other parameters of the vertical protruding reinforcement and ring beam reinforcement;

[0107] b) Fixing and Connection: Use methods such as rebar connectors, welding, or knotting to fix and connect the vertically extending rebars to the ring beam rebars. Ensure the connection is firm, tight, and complies with relevant construction specifications;

[0108] c) Select appropriate tools, such as syringes or caulking guns, to inject high-performance concrete or other caulking materials into the gaps. During the injection process, it is necessary to maintain a uniform injection speed and pressure to ensure that the caulking material fills the gaps completely.

[0109] d) After injecting the filler material, use tools such as scrapers and sealing tools to fill the gap with the filler material and ensure that the filler material is flush with the surface of the gap;

[0110] e) Perform appropriate curing work according to the requirements of the grout material; that is, wait for the grout material to cure or dry for a period of time to ensure the filling effect and strength;

[0111] f) Post-processing: After the high-performance concrete and other joint filler materials reach the required strength, post-processing work is carried out, such as surface finishing, to form the final structure.

[0112] This step involves injecting and filling the gaps with sealant, which increases the connection strength between components, improves the stability and durability of the overall structure, and prevents water, air, dust, and other substances from entering the gaps between components, thereby improving the building's sealing performance.

[0113] Step (6): Apply plaster and waterproof coating to the entire surface.

[0114] After completing steps (4) and (5) to reinforce the wall, this step involves overall plastering of the wall to coordinate the reinforced area with the surrounding walls, and applying waterproof coating to enhance the waterproof performance of the wall.

[0115] Based on the above steps, the present invention can achieve reinforcement and energy-saving renovation of masonry exterior walls. Furthermore, the design and manufacture of modular wall panels can greatly reduce construction time and costs, while also improving construction safety and efficiency.

[0116] The following application examples further illustrate the implementation process and effects of the present invention.

[0117] When using the present invention to reinforce and renovate masonry exterior walls for energy conservation, the corresponding implementation process is as follows: Figures 1 to 7 As shown:

[0118] 1. Measure the thickness and dimensions of the masonry exterior wall and design a reinforcement plan.

[0119] First, the masonry exterior wall to be reinforced needs to be measured to obtain relevant parameters such as its thickness and dimensions. Based on these parameters and the actual conditions of the building, a suitable reinforcement plan for the wall can be designed.

[0120] Specific reinforcement solutions may include the insertion position, number, and spacing of pull-out insulation nails, as well as the size and shape of modular reinforcement panels.

[0121] For example, the reinforcement and energy-saving renovation of masonry exterior walls in civil buildings can be designed according to the "Code for Design of Strengthening Masonry Structures," the "Code for Design of Masonry Structures," and the "Code for Thermal Design of Civil Buildings." Specific reinforcement schemes and the technical standards or requirements they are based on may vary depending on the region, structural type, and design requirements. Therefore, before implementing a specific reinforcement scheme, an assessment and design should be conducted in accordance with local regulations and standards.

[0122] 2. Manufacture reinforcement materials, including modular wall panels, pull-out insulation nails, etc.

[0123] According to the reinforcement scheme designed in step (1), corresponding reinforcement materials need to be manufactured, including modular wall panels, pull-out insulation nails, high-performance concrete (such as UHPC fine stone, micro-expansion concrete, etc.).

[0124] The modular wall panel structure here is as described above. The pull-out insulation nails can be made of galvanized or stainless steel with a tensile strength of not less than 60kN. The structure of the high-performance concrete can be determined according to actual needs and is not limited here.

[0125] 3. Drill holes in the original masonry wall and reserve insulation nail holes at corresponding positions on the modular wall panels.

[0126] According to the reinforcement plan, insulation nail holes are pre-drilled at corresponding positions on the modular wall panels, and holes are drilled in the wall to facilitate the installation of pull-out insulation nails along the original masonry wall and the insulation nail holes in the modular wall panels after the modular wall panels are installed. The number, position, and spacing of the pull-out insulation nails should meet the design requirements to ensure the reinforcement effect. After the pull-out insulation nails are inserted, high-performance mortar or concrete (such as UHPC fine aggregate or micro-expansion concrete) is injected.

[0127] 4. Assemble modular wall panels.

[0128] The prefabricated modular wall panels are spliced ​​and installed along the outer surface of the original masonry exterior wall using a method that avoids exposed reinforcement and uses tongue and groove joints to form a single reinforced panel.

[0129] 5. Install anti-pull-out insulation nails 9 to fix the modular wall panel 1 to the original masonry exterior wall 10.

[0130] After the modular wall panels are installed, pull-out insulation nails will be installed along the original masonry wall and the insulation nail holes in the modular wall panels to ensure the positioning and effective connection of the wall panels. At the same time, the joints for installing the pull-out insulation nails will be filled with grout (such as high-performance mortar or concrete) to prevent air and water penetration and enhance the insulation performance of the wall.

[0131] 6. A connection structure is installed between the modular wall panel and the original masonry exterior wall.

[0132] For the connection joints between the modular wall panels and the original masonry exterior walls, high-performance concrete (such as UHPC fine stone and micro-expansion concrete) is used for filling and sealing to prevent the penetration of air and water, while also enhancing the thermal insulation performance of the wall.

[0133] 7. Treat the joints to improve the overall performance of the wall.

[0134] ① For the connection between modular wall panels, each wall panel adopts a non-reinforcing bar setting. Each modular wall panel can have reinforcing bars extending in both directions along the panel to facilitate connection with surrounding components. Alternatively, tongue and groove joints can be set at the edges of the wall panels to further enhance the connection performance of the modular reinforced wall panels.

[0135] The panels are spliced ​​according to the tongue and groove joint, with fiberglass mesh arranged along the tongue and groove surface of the modular wall panels, and high-performance concrete (such as UHPC fine stone or micro-expansion concrete) is applied to improve the connection performance between the walls.

[0136] ② For the connection between the integrated wall panel and the ring beam, drill holes at the original ring beam location, insert and tie the reinforcing bars extending from the upper part of the integrated wall panel, and use high-performance concrete (such as UHPC, micro-expansion fine stone concrete) to fill the connection joint in place to improve the overall load-bearing performance between the wall and the ring beam.

[0137] 8. Apply plaster and waterproof coating to the entire surface.

[0138] After reinforcing the wall, overall plastering is required to coordinate the reinforced area with the surrounding walls. Waterproof coating should then be applied to enhance the wall's waterproof performance.

[0139] The reinforced wall panels here can also be coated with decorative materials or paints to meet different architectural styles and design requirements.

[0140] As can be seen from the above examples, the renovation scheme provided by the present invention is applicable to energy-saving renovation projects of masonry exterior wall buildings, which can significantly improve the seismic resistance and thermal insulation performance of buildings, reduce indoor energy consumption, and also have high economic and social benefits.
