Description

Technical Field

[0001] This invention belongs to the field of building materials and construction, and in particular relates to an integrated keel composite exterior wall and its forming method. Background Technology

[0002] With the development of large-scale infrastructure projects, the direction of building development has gradually shifted towards carbon conservation and environmental protection. Prefabricated or modular building structures are gradually taking over the market. These structures are mass-produced in factories, and only require pouring or assembly on site, which greatly improves efficiency and reduces carbon emissions.

[0003] Hollow metal mesh sandwich panels are a common type of sandwich panel used in prefabricated walls. For example, the hollow metal mesh sandwich panel described in patent CN201410620789.0 (A Mesh Panel Exterior Wall with Insulation Layer and Construction Method) by Lianggu Construction Engineering (Shanghai) Co., Ltd. is composed of multiple mesh panels assembled together. The hollow holes formed by the mesh panels on both sides of the insulation layer and the insulation layer are staggered. Vertical joists are provided on both sides of the insulation layer, and the mesh panels are fixed to the vertical joists. Pouring is carried out after all the mesh panels and insulation layers are installed, thus ensuring the quality of the exterior wall. The exterior wall and insulation are constructed in one go, the construction method is simple, and there are no maintenance costs. After the cement mortar is applied to the exterior wall, the staggered holes formed on both sides of the insulation layer improve the load-bearing capacity of the exterior wall, correspondingly improving the insulation capacity of the exterior wall, reducing costs, and not affecting the subsequent interior and exterior decoration construction. However, this exterior wall has high overall energy consumption and is not convenient to construct. Therefore, this invention aims to propose an improved exterior wall and its forming method. Summary of the Invention

[0005] The second objective of this invention is to provide a more convenient method for forming exterior walls that is more in line with the concept of carbon neutrality.

[0006] To achieve one of the above objectives, the present invention first provides an integrated keel-type composite exterior wall, characterized in that it comprises:

[0007] Multiple rows of supporting keels are arranged side by side and supported between the main structure of the floor.

[0008] The outer mesh plate is arranged on the outside of the supporting keel;

[0009] The exterior wall panel is arranged outside the outer mesh panel;

[0010] An inner insulation board is located inside the outer mesh board and forms at least a waterproof layer between them.

[0014] Preferably, it also includes a third positioning element; the section of the tie rod near the outer mesh plate is implemented as an intermediate threaded section, the third positioning element is threaded to the intermediate threaded section and cooperates with the first positioning element to clamp the outer wall panel, the outer mesh plate and the first keel; the second positioning element is threaded to the internal threaded section of the tie rod and abuts against the second keel.

[0015] Preferably, the waterproof layer is applied at least between the outer mesh panel and the first keel.

This significantly improves adaptability and allows for wide application in external wall installations, with high compatibility with various construction projects.

[0097] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0098] Example 1:

[0099] Please see Figures 1-9 And focus on referencing Figure 1 , Figure 2 , Figure 5 and Figure 6 This embodiment provides an integrated keel-type exterior wall, including multiple rows of supporting keels 1, external mesh panels 3, external wall panels 4, and internal insulation panels 9. The multiple rows of supporting keels 1 are arranged side-by-side and supported between the main building structures. The external mesh panels 3 are arranged outside the supporting keels 1, the external wall panels 4 are arranged outside the external mesh panels 3, and the internal insulation panels 9 are located inside the external mesh panels 3, forming at least a waterproof layer 5 between them. The supporting keels 1, external mesh panels 3, external wall panels 4, and internal insulation panels 9 are integrally connected by connectors 2. The supporting keels 1 serve as the load-bearing structure, and multiple connectors 2 are correspondingly installed on the multiple rows of supporting keels 1, then integrally connected to form the supporting keels 1, external mesh panels 3, external wall panels 4, and internal insulation panels 9.

[0100] It should be noted that, in this embodiment, as a preferred implementation, the outer mesh panel 3, the outer wall panel 4, and the inner insulation panel 9 have a continuous structure. Therefore, this embodiment does not specifically limit whether these components are a single panel structure or multiple panels assembled continuously.

[0101] The supporting keel 1 serves as the overall load-bearing structure. Considering its structural strength and lightness, this is a preferred embodiment in this case. Please refer to the following references. Figure 1 and Figure 13 , Figure 15 and Figure 17Each row of supporting keels 1 includes a first keel 11 and a second keel 12. The inner insulation board 9 is sandwiched between the first keel 11 and the second keel 12 and connected and fixed by connectors 2. Taking the outside and inside of the wall as references, the first keel 11 is located closer to the outside of the wall, and the second keel 12 is located closer to the inside of the wall. The outer wall panel 4 and the outer mesh panel 3 are connected and tied to the first keel 11 by connectors 2. Preferably, the first keel 11 and the second keel 12 are made of channel steel or H-beam steel.

[0102] Multiple first keels 11 are arranged as a row near the outside of the wall, and multiple second keels 12 are arranged as a row near the inside of the wall.

[0103] Connector 2 integrates and connects the above components, achieving fully prefabricated assembly and facilitating on-site assembly and hoisting transportation. For a preferred embodiment of this work, please refer to the following references. Figure 3 , Figure 13 and Figure 17 The connecting component 2 includes a tie rod 21, a first positioning component 22, and a second positioning component 23. The tie rod 21 has an external threaded section 211 and an internal threaded section 212 at both ends. The tie rod 21 passes through and connects the supporting keel 1, the outer mesh plate 3, the outer wall panel 4, and the inner insulation board 9. The first positioning component 22 is threadedly connected to the external threaded section 211 of the tie rod 21 and abuts against the outer wall panel 4. The second positioning component 23 is threadedly connected to the internal threaded section 212 of the tie rod 21 and abuts against the supporting keel 1. Preferably, the first positioning component 22 and the second positioning component 23 are T-shaped positioning nuts. Furthermore, since the first positioning component 22 is outside the wall, to prevent thermal bridging caused by the tie rod 21 being made of metal, an insulation material, such as a layer of injection-molded material, is wrapped around the first positioning component 22.

[0104] Please see Figure 2 , Figure 3 , Figure 4 , Figure 14 and Figure 15 After the outer mesh panel 3 is installed, the waterproof layer 5 can be sprayed. At this time, the inner insulation panel 9 has not yet been installed. To facilitate structural stability, the connector 2 also includes a third positioning member 24. The section of the tie rod 21 near the outer mesh panel 3 is implemented as a middle threaded section 213. The third positioning member 24 is threaded to the middle threaded section 213 and cooperates with the first positioning member 22 to clamp the outer wall panel 4, the outer mesh panel 3, and the first keel 11. The second positioning member 23 is threaded to the inner threaded section 212 of the tie rod 21 and abuts against the second keel 12. Therefore, the tie rod 21 is implemented as "three positioning + two areas". The three positioning members divide two connection areas. The first positioning member 22 and the third positioning member 24 clamp and fix the outer wall panel 4, the outer mesh panel 3, and the first keel 11; the second positioning member 23 and the third positioning member 24 clamp and fix the inner insulation panel 9 and the second keel 12.

[0105] For further details, please refer to Figure 5 , Figure 15 and Figure 16 The aforementioned waterproof layer 5 is at least applied between the outer mesh panel 3 and the first keel 11. It is preferably formed using a spray-paste process, directly spraying a waterproof mortar layer onto the outer mesh panel 3. Preferably, the outer mesh panel 3 is made of continuously corrugated steel wire mesh, which serves as a structural layer and can be filled with mortar; alternatively, only the outer layer of waterproof mortar can be sprayed to form a hollow insulation space inside. The hollow structure provides excellent thermal insulation, and only the waterproof layer 5 needs to be formed, eliminating the need for the traditional corrugated mesh filling process. Furthermore, the thickness of the outer mesh panel 3 is not less than 3 cm, while the thickness of the waterproof layer 5 is not less than 0.5 cm.

[0106] Please see Figure 6 and Figure 17 After the waterproof layer 5 is completed, the inner insulation board 9 can be installed. Since the inner insulation board 9 is built-in, the material requirements are lower, and more economical foam insulation board can be used. There is no need to consider the issue of flame-retardant and non-combustible materials, which is more economical. Specifically, when installing the inner insulation board 9, first remove the second keel 12, install the inner insulation board 9 and drill holes to insert the tie rod 21, and then install the second keel 12 and the second positioning part 23 for connection and fixation.

[0107] For further details, please refer to Figure 7 , Figure 8 and Figure 17 , Figure 18 To facilitate plastering and decoration of the interior walls, and to protect the internal insulation board 9, as a preferred embodiment of this invention, this embodiment also includes an inner mesh plate 6. The inner mesh plate 6 is installed on the second keel 12 by a second positioning member 23, that is, the inner mesh plate 6 is fixed to the second keel 12 by the tie rod 21 via the second positioning member 23. Specifically, the inner mesh plate 6 can be either corrugated wire mesh or flat wire mesh, preferably corrugated wire mesh, i.e., a continuously formed wave mesh.

[0108] Please see Figure 18 A smoothing layer 7 is formed on the inner mesh panel 6, comprising a wall mortar layer formed on the inner mesh panel 6 and a plaster layer smoothed from the wall mortar layer. Specifically, the wall mortar layer can also be formed by spraying on one side. Since the overall load-bearing structure is supported by the keel 1, the wall mortar layer can either fill the inner mesh panel 6 completely or be sprayed onto the inner mesh panel 6 to form a wall surface. Then, plaster is directly applied to the smoothing layer 7 to form a plaster layer. At this time, the inner insulation board 9 is protected by the mortar layers on both sides for waterproofing and fire resistance, resulting in a longer service life and greater safety. Furthermore, in conjunction with the inner mesh panel 6 and the outer mesh panel 3, its thermal insulation, sound insulation, and heat insulation effects are better.

[0109] As an exterior decoration and external structure, the exterior wall panel 4, compared to traditional exterior leaf panels, in this embodiment includes an exterior wall insulation board 41 and an exterior wall cladding 42. The exterior wall cladding 42 is fixedly connected to or formed into the exterior wall insulation board 41. The exterior wall insulation board 4 is preferably made of Class A non-combustible material to provide absolute flame retardancy and is also lighter. The exterior wall cladding 42 can be formed using a plastering process to create an exterior wall plaster surface, or decorative panels such as facing stone can be installed by connecting the tie rod 21 and the first positioning member 22. Furthermore, when using decorative panels, it is preferable to paste the decorative panels onto the exterior wall insulation board 41. The exterior wall insulation board 4, together with the hollow layer of the outer mesh panel 3, can insulate against most of the external heat.

[0110] It should be noted that, Figures 1-9 The structure is displayed sequentially from the installation order, using a three-dimensional perspective. Figures 13-18 The structures are displayed sequentially from a top-down perspective, following the installation order.

[0111] The beneficial effects of this embodiment are:

[0112] This invention integrates the outer mesh panel 3, the outer wall panel 4, and the inner insulation panel 9 into a single unit. It can be assembled in the factory and then transported to the site for assembly, or the individual components can be transported to the site for assembly. This greatly improves construction efficiency, reduces energy consumption, reduces external wall construction, and increases safety. The overall structure reduces its weight and enriches its functions, achieving integrated installation of thermal insulation and waterproofing, which is more in line with the carbon neutrality concept.

[0113] Support keel 1 can support the entire structure with two sets of keels, making the overall structure lighter, easier to transport and assemble, and easier to construct, shape and install.

[0114] By connecting the tie rod 21, the first positioning component 22, the second positioning component 23 and the third positioning component 24, the various components are connected, which truly realizes the integrated installation of the fully prefabricated structure. This reduces the technical requirements for construction personnel, reduces construction costs and improves construction efficiency.

[0115] The exterior wall panel 4 uses Class A non-combustible materials to achieve thermal insulation and flame retardancy, and works with the inner insulation panel 9 to achieve double insulation, improving the insulation effect; and with the waterproof layer 5, it can further enrich the practical functions of the wall and also protect the structure of the inner insulation panel 9.

[0116] The outer mesh plate 3 is made of corrugated steel wire mesh to achieve structural reinforcement and waterproofing. The corrugated steel wire mesh can be filled or left hollow except for the waterproof layer 5, which can further achieve the thermal insulation effect.

[0117] For structures that require mortar pouring, spraying can be used instead of formwork, reducing formwork costs and improving construction efficiency.

[0118] Example 2:

[0119] Please see Figures 1-9 and combined Figures 10-18 This embodiment provides an integrated keel-type composite exterior wall forming method, including the following steps:

[0120] S1: Prefabrication, including prefabricated multi-row support keel 1, outer mesh panel 3, outer wall panel 4, inner insulation panel 9 and connector 2, ready for use.

[0121] For specific details, please refer to... Figure 1 and Figure 10 The supporting keel 1 serves as the overall load-bearing structure. Considering its structural strength and lightweight design, in this preferred embodiment, each row of supporting keels 1 includes a first keel 11 and a second keel 12. The inner insulation board 9 is sandwiched between the first keel 11 and the second keel 12 and connected and fixed by connectors 2. Taking the outside and inside of the wall as reference points, the first keel 11 is located closer to the outside of the wall, and the second keel 12 is located closer to the inside of the wall. The outer wall panel 4 and the outer mesh panel 3 are connected and tied to the first keel 11 by connectors 2. Preferably, the first keel 11 and the second keel 12 are made of channel steel or H-beam steel.

[0122] Multiple first keels 11 are arranged as a row near the outside of the wall, and multiple second keels 12 are arranged as a row near the inside of the wall.

[0123] Please refer to the following: Figure 3 , Figure 13 and Figure 17 The connector 2 integrates and connects the above components, achieving fully prefabricated assembly and facilitating on-site assembly and hoisting transportation. In a preferred embodiment of this invention, the connector 2 includes a tie rod 21, a first positioning element 22, and a second positioning element 23. The tie rod 21 has an external thread section 211 and an internal thread section 212 at both ends. The tie rod 21 passes through and connects the supporting keel 1, the outer mesh plate 3, the outer wall panel 4, and the inner insulation board 9. The first positioning element 22 is threaded to the external thread section 211 of the tie rod 21 and abuts against the outer wall panel 4. The second positioning element 23 is threaded to the internal thread section 212 of the tie rod 21 and abuts against the supporting keel 1. Preferably, the first positioning element 22 and the second positioning element 23 are T-shaped positioning nuts. Furthermore, since the first positioning element 22 is outside the wall, to prevent thermal bridging caused by the metal material of the tie rod 21, an insulation material, such as a layer of injection-molded material, is wrapped around the first positioning element 22.

[0124] Please see Figure 4 and Figure 15The connector 2 also includes a third positioning member 24. The middle portion or all of the connector 2 is implemented as a middle threaded section 213. The third positioning member 24 is threadedly connected to the middle threaded section 213 and cooperates with the first positioning member 22 to clamp the outer wall panel 4, the outer mesh panel 3, and the first keel 11. The second positioning member 23 is threadedly connected to the internal threaded section 212 of the tie rod 21 and abuts against the second keel 12. Therefore, the tie rod 21 is implemented as "three positioning + two areas," where the three positioning members divide two connection areas. The first positioning member 22 and the third positioning member 24 clamp and fix the outer wall panel 4, the outer mesh panel 3, and the first keel 11; the second positioning member 23 and the third positioning member 24 clamp and fix the inner insulation panel 9 and the second keel 12.

[0125] Specifically, the first positioning element 22, the second positioning element 23, and the third positioning element 24 can all be T-nuts.

[0126] Please combine Figure 10 and Figure 18 In this embodiment, the exterior wall panel 4 serves as both exterior decoration and external structure. Compared to traditional exterior leaf panels, the exterior wall panel 4 includes an exterior wall insulation board 41 and an exterior wall cladding 42. The exterior wall cladding 42 is fixedly connected to or formed into the exterior wall insulation board 41. The exterior wall insulation board 4 is preferably made of Class A non-combustible material to provide absolute flame retardancy and is also lighter. The exterior wall cladding 42 can be formed using a plastering process to create an exterior wall plaster surface, or decorative panels such as facing stone can be installed by connecting the tie rod 21 and the first positioning member 22. Furthermore, when using decorative panels, it is preferable to adhere the decorative panels to the exterior wall insulation board 41. The exterior wall insulation board 4, together with the hollow layer of the outer mesh board 3, can insulate against most of the external heat.

[0127] The outer mesh panel 3 uses a continuously corrugated steel wire mesh, and the inner insulation panel 9 can use a more economical foam insulation panel, without having to consider flame retardant and non-flammable material issues.

[0128] S2: Pre-assembly, multiple rows of supporting keels 1 are arranged side by side, and the outer mesh panel 3 and the outer wall panel 4 are pre-integratedly connected and assembled on the multiple rows of supporting keels 1 through multiple connectors 2 to form a combined outer wall assembly structure. The outer mesh panel 3 is located outside the supporting keel 1, and the outer wall panel 4 is located outside the outer mesh panel 3.

[0129] Specifically, tie rods 21 are inserted through the exterior wall panel 4. A first positioning element 22 is installed on the outside of the exterior wall panel 4. After the first positioning element 22 is installed on the external threaded section 211, the exterior wall panel 4 is laid on the ground. Then, the outer mesh panel 3 is laid, and the first keel 11 is arranged side-by-side and installed on the tie rods 21. The exterior wall panel 4, the outer mesh panel 3, and the first keel 11 are positioned and fixed by the third positioning element 24. Then, the second keel 12 is installed by installing the second positioning element 23 on the internal threaded section 212. At this point, a modular exterior wall assembly structure is formed. To facilitate transportation and hoisting, reinforcing back ribs 13 are installed on the second keel 12. Multiple reinforcing back ribs 13 and the second keel 12 form a grid structure. The reinforcing back ribs 13 are also installed using tie rods 21 and the second positioning element 23, and can be disassembled after being hoisted to the site.

[0130] The exterior wall panel 4 is an exterior wall panel with thermal insulation function. The side of the exterior wall panel 4 extends outward to form a column-covered thermal insulation area 81a, and the top of the exterior wall panel 4 extends upward to form a beam-covered thermal insulation area 82a. In the modular exterior wall assembly structure, there are multiple exterior wall panels 4, which are assembled from different standard sizes to adapt to different site size requirements.

[0131] S3: On-site installation involves hoisting the modular exterior wall assembly structure to the exterior wall installation location on the construction site and installing the supporting keel 1 between floors.

[0132] Specifically, the supporting keel 1 is installed between floors. In this embodiment, it is described in detail as being installed between structural beams 82 on two floors.

[0133] Please combine Figure 3 and Figure 10 The column insulation area 81a of the modular exterior wall assembly structure is wrapped around the columns of the main floor structure, and the beam insulation area 82a is wrapped around the horizontal beams of the main floor structure. At the installation location of the exterior wall, the beams and columns form a frame structure, with structural columns 81 on both sides and structural beams 82 above and below. Therefore, the column insulation area 81a is wrapped around the columns (structural columns 81) of the main floor structure to prevent heat loss from the columns, and the beam insulation area 82a is wrapped around the horizontal beams (structural beams 82) of the main floor structure to prevent heat loss from the beams. Since each floor has the modular exterior wall assembly structure installed, the modular exterior wall assembly structure of each floor only needs to form the beam insulation area 82a at the top. On the sides, depending on the span of the exterior wall, it can be determined whether the modular exterior wall assembly structure needs to be assembled to adaptively adjust the column insulation area 81a.

[0134] S4: Waterproof layer 5 is formed by spraying mortar onto the outer mesh plate 3 to form waterproof layer 5.

[0135] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 14 and Figure 15 A waterproof mortar layer is formed by spraying mortar directly onto the outer mesh panel 3. Preferably, the outer mesh panel 3 is made of continuously corrugated steel wire mesh, which serves as a structural layer and can be filled with mortar; alternatively, only the outer layer of waterproof mortar can be sprayed to form a hollow insulation space inside. The hollow structure can effectively provide thermal insulation, and only the waterproof layer 5 needs to be formed, eliminating the need for the traditional corrugated mesh filling process. Furthermore, the thickness of the outer mesh panel 3 is not less than 3cm, while the thickness of the waterproof layer 5 is not less than 0.5cm.

[0136] S5: Internal insulation installation, the internal insulation board 9 is installed on the waterproof layer 5 and fixed by the supporting keel 1.

[0137] For details, please refer to Figure 6 and Figure 17 After the waterproof layer 5 is completed, the inner insulation board 9 can be installed. Since the inner insulation board 9 is built-in, the material requirements are lower, and more economical foam insulation board can be used. There is no need to consider flame retardant and non-flammable material issues, which is more economical. Specifically, when installing the inner insulation board 9, first remove the second keel 12, install the inner insulation board 9 and drill holes to insert the tie rod 21, and then install the second keel 12 and the second positioning part 23 for connection and fixation.

[0138] Step S6: The wall surface plastering layer 7 is formed. An inner mesh plate 6 is installed on the inside of the insulation board. A wall mortar layer is formed by spraying mortar onto the inner mesh plate 6. The plastering layer is then formed on the wall mortar layer.

[0139] For details, please refer to Figure 7 , Figure 8 and Figure 17 , Figure 18 To facilitate plastering and decoration of the interior walls, and to protect the internal insulation board 9, as a preferred embodiment of this invention, this embodiment also includes an inner mesh plate 6. The inner mesh plate 6 is installed on the second keel 12 by a second positioning member 23, that is, the inner mesh plate 6 is fixed to the second keel 12 by the tie rod 21 via the second positioning member 23. Specifically, the inner mesh plate 6 can be either corrugated wire mesh or flat wire mesh, preferably corrugated wire mesh, i.e., a continuously formed wave mesh.

[0140] A smoothing layer 7 is formed on the inner mesh panel 6. This smoothing layer 7 includes a wall mortar layer formed on the inner mesh panel 6 and a plaster layer smoothed and formed on the wall mortar layer. Specifically, the wall mortar layer can also be formed by spraying on one side. Since the overall load-bearing structure is supported by the keel 1, the wall mortar layer can either fill the inner mesh panel 6 completely or be sprayed onto the inner mesh panel 6 to form a wall surface. Then, plaster is directly applied on the smoothing layer 7 to form a plaster layer. At this time, the inner insulation board 9 is protected by the mortar layers on both sides for waterproofing and fire resistance, resulting in a longer service life and greater safety. In addition, in conjunction with the inner mesh panel 6 and the outer mesh panel 3, its thermal insulation, sound insulation, and heat insulation effects are better.

[0141] The beneficial effects of this embodiment are:

[0142] This invention integrates the outer mesh panel 3, outer wall panel 4, and inner insulation panel 9 into a modular exterior wall assembly structure. This structure can be assembled in the factory and transported to the site for further assembly, achieving a fully prefabricated installation. This significantly improves adaptability and allows for wide application in exterior wall installations, with high compatibility with various construction projects. It greatly enhances construction efficiency, reduces energy consumption, minimizes external construction work, and increases safety. The overall structure reduces weight and enriches functionality, achieving integrated thermal insulation and waterproofing, which is more in line with the carbon neutrality concept.

[0143] Support keel 1 can support the entire structure with two sets of keels, making the overall structure lighter, easier to transport and assemble, and easier to construct, shape and install.

[0144] By connecting the tie rod 21, the first positioning component 22, the second positioning component 23 and the third positioning component 24, the various components are connected, which truly realizes the integrated installation of the fully prefabricated structure. This reduces the technical requirements for construction personnel, reduces construction costs and improves construction efficiency.

[0145] The exterior wall panel 4 uses Class A non-combustible materials to achieve thermal insulation and flame retardancy, and works with the inner insulation panel 9 to achieve double insulation, improving the insulation effect; and with the waterproof layer 5, it can further enrich the practical functions of the wall and also protect the structure of the inner insulation panel 9.

[0146] The outer mesh plate 3 is made of corrugated steel wire mesh to achieve structural reinforcement and waterproofing. The corrugated steel wire mesh can be filled or left hollow except for the waterproof layer 5, which can further achieve the thermal insulation effect.

[0147] For structures that require mortar pouring, spraying can be used instead of formwork, reducing formwork costs and improving construction efficiency.

[0148] By detachably installing the reinforcing back rib 13 on the supporting keel 1, it is convenient to protect the overall structure and hoist it during transportation;

[0149] The exterior wall surface formed by the exterior wall panel 4 can be assembled by using exterior wall panels 4 of different sizes. The factory only needs to prefabricate a few common sizes; it can then be combined to meet the size requirements of various construction sites. It is highly flexible and can be installed by means of tie rods 21, which is simple and convenient.

[0150] Example 3:

Considering its structural strength and lightweight design, in this preferred embodiment, each row of supporting keels 1 includes a first keel 11 and a second keel 12. The inner insulation board 9 is sandwiched between the first keel 11 and the second keel 12 and connected and fixed by connectors 2. Taking the outside and inside of the wall as reference points, the first keel 11 is located closer to the outside of the wall, and the second keel 12 is located closer to the inside of the wall. The outer wall panel 4 and the outer mesh panel 3 are connected and tied to the first keel 11 by connectors 2.

[0154] Multiple first keels 11 are arranged as a row near the outside of the wall, and multiple second keels 12 are arranged as a row near the inside of the wall.

[0155] Please refer to the following: Figure 3 , Figure 13 and Figure 17 The connector 2 integrates and connects the above components, achieving fully prefabricated assembly and facilitating on-site assembly and hoisting transportation. In a preferred embodiment of this invention, the connector 2 includes a tie rod 21, a first positioning element 22, and a second positioning element 23. The tie rod 21 has an external thread section 211 and an internal thread section 212 at both ends. The tie rod 21 passes through and connects the supporting keel 1, the outer mesh plate 3, the outer wall panel 4, and the inner insulation board 9. The first positioning element 22 is threaded to the external thread section 211 of the tie rod 21 and abuts against the outer wall panel 4. The second positioning element 23 is threaded to the internal thread section 212 of the tie rod 21 and abuts against the supporting keel 1. Preferably, the first positioning element 22 and the second positioning element 23 are T-shaped positioning nuts. Furthermore, since the first positioning element 22 is outside the wall, to prevent thermal bridging caused by the metal material of the tie rod 21, an insulation material, such as a layer of injection-molded material, is wrapped around the first positioning element 22.

[0156] Please combine Figure 4 and Figure 15 The connector 2 also includes a third positioning member 24. The middle portion or all of the connector 2 is implemented as a middle threaded section 213. The third positioning member 24 is threadedly connected to the middle threaded section 213 and cooperates with the first positioning member 22 to clamp the outer wall panel 4, the outer mesh panel 3, and the first keel 11. The second positioning member 23 is threadedly connected to the internal threaded section 212 of the tie rod 21 and abuts against the second keel 12. Therefore, the tie rod 21 is implemented as "three positioning + two areas," where the three positioning members divide two connection areas. The first positioning member 22 and the third positioning member 24 clamp and fix the outer wall panel 4, the outer mesh panel 3, and the first keel 11; the second positioning member 23 and the third positioning member 24 clamp and fix the inner insulation panel 9 and the second keel 12.

[0157] Specifically, the first positioning element 22, the second positioning element 23, and the third positioning element 24 can all be T-nuts.

[0158] Please combine Figure 10 and Figure 18 In this embodiment, the exterior wall panel 4 serves as both exterior decoration and external structure. Compared to traditional exterior leaf panels, the exterior wall panel 4 includes an exterior wall insulation board 41 and an exterior wall cladding 42. The exterior wall cladding 42 is fixedly connected to or formed into the exterior wall insulation board 41. The exterior wall insulation board 4 is preferably made of Class A non-combustible material to provide absolute flame retardancy and is also lighter. The exterior wall cladding 42 can be formed using a plastering process to create an exterior wall plaster surface, or decorative panels such as facing stone can be installed by connecting the tie rod 21 and the first positioning member 22. Furthermore, when using decorative panels, it is preferable to adhere the decorative panels to the exterior wall insulation board 41. The exterior wall insulation board 4, together with the hollow layer of the outer mesh board 3, can insulate against most of the external heat.

[0159] The outer mesh panel 3 uses a continuously corrugated steel wire mesh, and the inner insulation panel 9 can use a more economical foam insulation panel, without having to consider flame retardant and non-flammable material issues.

[0160] S2: On-site installation, multiple rows of supporting keels 1 are installed between floors, and the outer mesh panel 3 and the outer wall panel 4 are installed on the outside of the supporting keel 1 in sequence through connectors 2.

[0161] For specific details, please refer to... Figure 1 and Figure 13 The first keel 11 and the second keel 12 are fixed between the structural beams 82 of the floor, and the outer mesh plate 3 and the outer wall plate 4 are installed on the first keel 11 in sequence and clamped and positioned by the first positioning member 22 and the third positioning member 24. The second positioning member 23 is threaded to the internal thread section 212 and abuts against the second keel 12.

[0162] Please see Figure 10 The exterior wall panel 4 is an exterior wall panel with thermal insulation function. The side of the exterior wall panel 4 extends outward to form a column-covered thermal insulation area 81a, and the top of the exterior wall panel 4 extends upward to form a beam-covered thermal insulation area 82a.

[0163] The column insulation area 81a is applied to the columns of the main floor structure, and the beam insulation area 82a is applied to the beams of the main floor structure. At the installation location on the exterior wall, the beams and columns form a frame structure, with structural columns 81 on both sides and structural beams 82 above and below. Therefore, the column insulation area 81a is applied to the columns (structural columns 81) of the main floor structure to prevent heat loss from the columns, and the beam insulation area 82a is applied to the beams (structural beams 82) of the main floor structure to prevent heat loss from the beams. Since each floor has a modular exterior wall assembly structure, the modular exterior wall assembly structure on each floor only needs to form the beam insulation area 82a at the top. On the sides, the need for assembling the modular exterior wall assembly structure can be adjusted according to the span of the exterior wall.

[0164] As described above, there are multiple exterior wall panels 4, which are implemented in different sizes. During installation, exterior wall panels 4 of different sizes are combined and installed on the supporting keel 1 according to the different specifications of exterior wall size requirements.

[0165] S3: Waterproof layer 5 is formed by spraying mortar onto the outer mesh plate 3 to form waterproof layer 5.

[0166] For specific details, please refer to... Figure 5 and Figure 16 A waterproof mortar layer is formed by spraying mortar directly onto the outer mesh panel 3. Preferably, the outer mesh panel 3 is made of continuously corrugated steel wire mesh, which serves as a structural layer and can be filled with mortar; alternatively, only the outer layer of waterproof mortar can be sprayed to form a hollow insulation space inside. The hollow structure can effectively provide thermal insulation, and only the waterproof layer 5 needs to be formed, eliminating the need for the traditional corrugated mesh filling process. Furthermore, the thickness of the outer mesh panel 3 is not less than 3cm, while the thickness of the waterproof layer 5 is not less than 0.5cm.

[0167] S4: Internal insulation installation, install the internal insulation board 9 on the waterproof layer 5 and fix it through the supporting keel 1.

[0168] For specific details, please refer to... Figure 6 and Figure 17After the waterproof layer 5 is completed, the inner insulation board 9 can be installed. Since the inner insulation board 9 is built-in, the material requirements are lower, and more economical foam insulation board can be used. There is no need to consider flame retardant and non-flammable material issues, which is more economical. Specifically, when installing the inner insulation board 9, first remove the second keel 12, install the inner insulation board 9 and drill holes to insert the tie rod 21, and then install the second keel 12 and the second positioning part 23 for connection and fixation.

[0169] Step S5: The wall surface plastering layer 7 is formed. An inner mesh plate 6 is installed on the inside of the insulation board. A wall mortar layer is formed by spraying mortar onto the inner mesh plate 6. The wall mortar layer is then plastered to form a plaster layer.

[0170] For specific details, please refer to... Figure 7 , Figure 8 , Figure 9 , Figure 17 and Figure 18 To facilitate plastering and decoration of the interior walls, and to protect the internal insulation board 9, as a preferred embodiment of this invention, this embodiment also includes an inner mesh plate 6. The inner mesh plate 6 is installed on the second keel 12 by a second positioning member 23, that is, the inner mesh plate 6 is fixed to the second keel 12 by the tie rod 21 via the second positioning member 23. Specifically, the inner mesh plate 6 can be either corrugated wire mesh or flat wire mesh, preferably corrugated wire mesh, i.e., a continuously formed wave mesh.

[0171] A smoothing layer 7 is formed on the inner mesh panel 6.

Specifically, the wall mortar layer can also be formed by spraying on one side. Since the overall load-bearing structure is supported by the keel 1, the wall mortar layer can either fill the inner mesh panel 6 completely or be sprayed onto the inner mesh panel 6 to form a wall surface. Then, plaster is directly applied on the smoothing layer 7 to form a plaster layer. At this time, the inner insulation board 9 is protected by the mortar layers on both sides for waterproofing and fire resistance, resulting in a longer service life and greater safety. In addition, in conjunction with the inner mesh panel 6 and the outer mesh panel 3, its thermal insulation, sound insulation, and heat insulation effects are better.

[0172] The beneficial effects of this embodiment are:

This significantly improves adaptability and allows for wide application in exterior wall installations, with high compatibility with various construction projects. It also greatly enhances construction efficiency, reduces energy consumption, minimizes external wall construction, and increases safety.
