Description

Technical Field

[0001] This application belongs to the field of building wall panel technology, specifically relating to a building thermal insulation wall panel and its construction method. Background Technology

[0002] Building insulation wall panels are composite wall components used in the external envelope of buildings. Their core feature is that while fulfilling structural or enclosing functions, they significantly reduce the building's heating and cooling energy consumption by integrating high-efficiency insulation materials. Based on different production processes and construction methods, building insulation wall panels are currently mainly divided into two categories: prefabricated assembled panels and cast-in-place panels.

[0003] The typical construction method for cast-in-place sandwich insulated wall panels is as follows: First, the insulation board with connectors is fixed to the outside of the wall reinforcement as a permanent external formwork. Then, formwork is erected on both the inner and outer sides of the insulation board, and concrete is poured simultaneously to form a sandwich structure of "concrete-insulation layer-concrete".

[0004] The inventors discovered that the existing construction methods described above have several shortcomings in practical applications: Firstly, the construction process requires that the concrete on both the inner and outer sides be poured and vibrated simultaneously and evenly. Otherwise, uneven pressure can easily cause the insulation board to shift or deform, making construction control difficult and with low tolerance for error. Secondly, the pouring process is in a closed state, making it impossible to directly observe the fullness of the concrete filling in the interlayer and the pouring height. Quality control relies heavily on construction experience and lacks reliable and intuitive monitoring methods. Third, the inner and outer concrete layers mainly rely on the insulation board connectors and concrete bonding force for bonding, lacking effective rigid mechanical anchoring in the later stage. Under temperature stress or external force, there is a risk of delamination, which affects the long-term stability of the overall structure. Summary of the Invention

[0005] This application provides a building insulation wall panel and its construction method, which aims to improve construction controllability and ensure a strong bond between the inner and outer concrete layers.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A building insulation wall panel is provided, comprising: The outer frame is used to fix the frame to the outside of the wall, and its axis is perpendicular to the wall surface. The insulation layer is coaxially disposed within the outer frame, and the two sides of the outer frame extend to the two sides of the insulation layer in the width direction, so as to form a processing space inside the insulation layer and an installation space outside the insulation layer; the insulation layer is provided with a plurality of reserved holes spaced apart in the vertical direction, and each reserved hole is through the insulation layer in the thickness direction. An inner concrete layer is filled within the processing space; and The outer concrete layer is composed of multiple layers of precast panels stacked vertically, each corresponding to one of the reserved holes, and is disposed within the installation space. The precast plate is provided with a guide hole that is coaxially connected to the corresponding reserved hole, and a composite plate is inserted into the guide hole; The composite plate includes an outer filling module embedded in the guide hole, and an inner filling module connected to the outer filling module and embedded in the reserved hole.

[0007] In one possible implementation, the outer frame is provided with a plurality of feed ports spaced apart in the vertical direction, the feed ports being used to fill concrete to form the inner concrete layer; The plurality of feed inlets correspond one-to-one with the plurality of reserved holes, and the corresponding feed inlets and reserved holes are on the same horizontal plane, or the feed inlets are below the corresponding reserved holes.

[0008] In one possible implementation, the composite plate further includes: A limiting plate is provided on the outside of the composite panel and is connected to the outer concrete layer through a connecting structure to restrict the outward movement of the composite panel.

[0009] In one possible implementation, the connection structure includes: The first alignment hole is used to be opened on the wall surface and penetrates into the inner side of the wall in a direction perpendicular to the wall surface; The second alignment hole is formed on the insulation layer and is coaxially arranged with the first alignment hole. The third alignment hole is formed on the precast plate and is coaxially arranged with the second alignment hole; and The connecting bolt is inserted into the interconnected first alignment hole, second alignment hole and third alignment hole, with its head abutting the outer side of the limiting plate and its end extending into the inner side of the wall; the end of the connecting bolt is threadedly connected to a support member for abutting the inner side of the wall.

[0010] In one possible implementation, the limiting plate has a guide cylinder; The guide cylinder adopts a hollow straight cylinder structure, and when the limiting plate abuts against the outer side of the composite plate, the guide cylinder passes through the third alignment hole, the second alignment hole and the first alignment hole in sequence to enter the inner side of the wall, so that part of the guide cylinder is in the processing space; The connecting bolt is inserted into the guide cylinder, with its head abutting the outer side of the limiting plate and its end extending into the inner side of the wall.

[0011] In one possible implementation, the guide cylinder is fixedly connected to the inner side of the limiting plate, and the limiting plate has a through hole coaxially communicating with the guide cylinder. The connecting bolt is inserted into the through hole, with its head abutting the outer side of the limiting plate and its end passing through the guide tube and extending into the inner side of the wall.

[0012] In one possible implementation, the outer diameter of the shank of the connecting bolt is equal to the inner diameter of the guide cylinder.

[0013] In one possible implementation, the support member includes: A bracket, fitted into the insertion portion of the connecting bolt, and having multiple legs abutting against the inner surface of the wall; and The mating nut is fixedly mounted on the bracket and threadedly connected to the connecting bolt.

[0014] In one possible implementation, the outer peripheral surface of the insulation layer has a slot, and the outer frame has a positioning hole communicating with the slot; the building insulation wall panel further includes: A limiting shaft is inserted into the interconnected slot and the positioning hole to restrict the movement of the insulation layer relative to the outer frame.

[0015] In this embodiment, the outer frame is fixed to the outside of the wall, with its two sides extending to both sides of the insulation layer, thus forming independent processing and installation spaces. This separation design allows the inner concrete layer to be poured and vibrated separately within the processing space, relieving the stringent constraint of simultaneous and balanced construction of the inner and outer concrete layers in traditional processes, fundamentally reducing the difficulty of construction control and operational risks. Multiple through-holes in the insulation layer, and corresponding composite plates inserted into the guide holes of the precast panels, constitute the core connection and monitoring components of this solution. The inner filling module of the composite plate is made of a low thermal conductivity material and embedded in the pre-drilled holes in the insulation layer, avoiding thermal bridging and providing an interface for subsequent connections; its outer filling module is embedded in the guide holes of the precast panels, ensuring the integrity of the precast outer concrete layer structure. Crucially, when the inner concrete is poured in the processing space and rises to the height of the pre-drilled holes, the concrete will cause the inner filling module of the composite plate to move slightly. This visible physical signal provides construction personnel with direct and reliable real-time feedback on the fullness of the pouring.

[0016] The aforementioned structural features work synergistically to systematically constitute a solution characterized by "process separation, visual monitoring, and rigid connection." Its working principle is as follows: First, the outer frame is used to achieve spatial separation, allowing the inner concrete layer to be poured independently under open conditions, ensuring construction freedom and quality visibility.

[0017] Secondly, by temporarily filling the reserved holes with composite panels made of low thermal conductivity materials, the continuity and effectiveness of the insulation layer are maintained during the construction phase, thus avoiding thermal bridging.

[0018] Subsequently, during the pouring of the inner concrete, the behavior of the concrete level pushing the inner end of the composite panel becomes an intuitive "level indicator," enabling construction workers to accurately judge the pouring height and compaction.

[0019] Finally, after the concrete has solidified, the composite panel acts as a pre-embedded rigid connector, with its inner filling module anchored to the inner concrete layer and its outer filling module locked to the precast outer concrete layer, thus forming a strong mechanical connection on both sides of the insulation layer.

[0020] Furthermore, this design achieves performance improvements in multiple aspects.

[0021] During the construction phase, it simplifies the complex three-dimensional synchronous pouring into a sequential planar operation, significantly improving construction efficiency, controllability, and safety; at the same time, it transforms the hidden works into an observable process, greatly ensuring the quality of pouring.

[0022] In terms of structural performance, the mechanical anchoring system composed of composite panels has far superior shear and pull-out resistance compared to traditional pure adhesive or flexible connectors. It effectively resists interlayer delamination that may be caused by temperature stress or external forces, ensuring the long-term integrity and stability of the sandwich structure.

[0023] In terms of thermal performance, the internal filling module, made of low thermal conductivity material, cuts off the physical heat conduction path through the reserved holes, ensuring the overall thermal insulation effect of the wall.

[0024] The building insulation wall panel provided in this embodiment, compared with existing technologies, innovatively solves the three core problems of traditional on-site cast-in-place sandwich insulation wall panels: difficult construction control, lack of quality visibility, and weak interlayer connections. This is achieved through an outer frame structure that can form an independent construction space, a low-thermal-conductivity composite panel that combines temporary sealing and final connection functions, and a casting-visual monitoring mechanism based on composite panel displacement. It not only simplifies the construction process and strengthens quality control, but also improves the structural safety and durability of the wall through reliable rigid mechanical connections, while ensuring the continuity of insulation performance. This results in a building wall that combines excellent workability, reliable quality, and high performance.

[0025] The technical solution adopted in this application also provides a construction method for building insulation wall panels, based on the building insulation wall panels proposed in any of the foregoing claims, including the following steps: A. Assemble the outer frame and the insulation layer, and fix the outer frame to the wall surface to form the processing space and the installation space; B. Place the single-layer precast panel into the installation space, so that the corresponding reserved hole and the guide hole are interconnected, and embed the outer filling module into the guide hole and the inner filling module into the reserved hole; C. Pour concrete into the processing space until the composite panel moves outward, then stop pouring; D. Push the composite plate inward to reset the outer filling module to be embedded in the guide hole and the inner filling module to be embedded in the reserved hole; E. Wait for the concrete in the processing space to solidify, forming part of the inner concrete layer; F. Repeat steps B to E until the outer concrete layer, which is composed of multiple layers of the precast slabs, abuts the inner top surface of the outer frame, and the inner concrete layer, which is composed of multiple portions of the inner concrete layer, abuts the inner top surface of the outer frame.

[0026] The beneficial effects of the construction method for building insulation wall panels provided in this embodiment are the same as those of the aforementioned building insulation wall panels, and will not be repeated here. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] Please refer to the following: Figures 1 to 13 The building insulation wall panel provided in this application is described below. The building insulation wall panel proposed in this application includes an outer frame 1, an insulation layer 2, an inner concrete layer 3, and an outer concrete layer 4.

[0034] The outer frame 1 is used to fix it on the outside of the wall, and its axis is perpendicular to the wall surface.

[0035] The insulation layer 2 is coaxially arranged inside the outer frame 1, and the inner circumferential surface of the outer frame 1 is connected to the outer circumferential surface of the insulation layer 2, with both sides extending to both sides of the width direction of the insulation layer 2, thereby forming a processing space inside the insulation layer 2 and an installation space outside the insulation layer 2.

[0036] The insulation layer 2 is provided with a plurality of reserved holes 21 spaced apart in the vertical direction. Each reserved hole 21 is through the thickness direction of the insulation layer 2 and extends along the width direction of the insulation layer 2.

[0037] The inner concrete layer 3 is filled into the processing space; in actual use, concrete needs to be injected into the processing space on site and wait for it to solidify and form.

[0038] The outer concrete layer 4 is composed of multiple layers of precast panels stacked vertically, each corresponding to a pre-drilled hole 21, and is placed within the installation space. Each precast panel is provided with a guide hole 41 that is coaxially connected to the corresponding pre-drilled hole 21, and a composite plate 5 is inserted into this guide hole 41.

[0039] In this embodiment, the composite plate 5 includes an outer filling module 51 and an inner filling module 52.

[0040] The outer filling module 51 is embedded in the guide hole 41, and the inner filling module 52 is connected to the outer filling module 51 and embedded in the reserved hole 21.

[0041] In this embodiment, the outer frame 1 is fixed to the outside of the wall and wraps the insulation layer 2. Its structure creates independent processing and installation spaces on both sides of the insulation layer 2. This separation design allows the inner concrete layer 3 to be poured and vibrated separately within the processing space, thereby relieving the stringent constraint of the traditional process that the inner and outer concrete must be constructed simultaneously and evenly, fundamentally reducing the difficulty of construction control and operational risks.

[0042] Multiple through-holes 21 on the insulation layer 2, and corresponding composite plates 5 inserted into the guide holes 41 of the precast slabs, constitute the core connection and monitoring components. The inner filling module 52 of the composite plate 5 is made of a low thermal conductivity material and is embedded in the through-holes 21 of the insulation layer 2. This design avoids the formation of thermal bridges and provides a physical interface for subsequent connections. Its outer filling module 51 is embedded in the guide holes 41 of the precast slabs, ensuring the structural integrity of the precast outer concrete layer 4.

[0043] Crucially, when the concrete is poured into the processing space and its level rises to the height of the reserved hole 21, the concrete will push the inner filling module 52 of the composite plate 5 to produce outward micro-movement; this visible physical signal provides construction personnel with direct and reliable real-time feedback on the fullness of the pouring, making the quality of the concealed works observable and controllable.

[0044] The aforementioned structural features work together to systematically form a solution characterized by "process separation, visual monitoring, and rigid connection." Its working principle is as follows: First, the outer frame 1 achieves spatial separation, allowing the inner concrete layer 3 to be poured independently under open conditions, ensuring construction freedom and quality visibility. Second, the pre-reserved holes 21 are temporarily filled by a composite plate 5 made of low thermal conductivity material, maintaining the continuity and effectiveness of the insulation layer 2 during construction. Subsequently, during the pouring of the inner concrete, the movement of the concrete level pushing the inner end of the composite plate 5 acts as a visual "level indicator," enabling construction personnel to accurately judge the pouring height and compaction. Finally, after the concrete solidifies, the composite plate 5 acts as a pre-embedded rigid connector, with its inner filling module 52 anchored to the inner concrete layer 3 and its outer filling module 51 locked to the precast outer concrete layer 4, thus forming a robust mechanical connection on both sides of the insulation layer 2.

[0045] This structure further enhances performance in multiple aspects. During construction, it simplifies the complex three-dimensional synchronous pouring into a sequential planar operation, significantly improving construction efficiency, controllability, and safety. Simultaneously, it transforms concealed works into an observable process, greatly ensuring pouring quality. In terms of structural performance, the mechanical anchoring system composed of composite panels 5 exhibits shear and pull-out resistance far superior to traditional pure adhesive or flexible connectors, effectively resisting interlayer delamination that may result from temperature stress or external forces, ensuring the long-term integrity and stability of the sandwich structure. Regarding thermal performance, the inner filling module 52, made of low thermal conductivity material, cuts off the physical heat conduction path through the pre-drilled holes 21, ensuring the overall thermal insulation effect of the wall.

[0046] The building insulation wall panel provided in this embodiment, compared with the prior art, innovatively solves the three core problems of traditional on-site cast-in-place sandwich insulation wall panels: difficult construction control, lack of quality visibility, and weak interlayer connection. This is achieved through an outer frame structure 1 that can form an independent construction space, a low thermal conductivity composite panel 5 that combines temporary sealing and final connection functions, and a casting visual monitoring mechanism based on the displacement of the composite panel 5. It not only simplifies the construction process and strengthens quality control, but also improves the structural safety and durability of the wall through reliable rigid mechanical connections, while ensuring the continuity of insulation performance, thus achieving a building wall with excellent workability, reliable quality, and high performance.

[0047] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the outer frame 1 has multiple feed ports 11 spaced apart in the vertical direction. Each feed port 11 is used to fill concrete to form the inner concrete layer 3.

[0048] Among them, multiple feed inlets 11 correspond one-to-one with multiple reserved holes 21. The corresponding feed inlets 11 and reserved holes 21 are on the same horizontal plane, or the feed inlets 11 are below the corresponding reserved holes 21. This design facilitates the injection of concrete from below or at the same level, ensuring that it can rise smoothly and push the composite plate 5 during pouring.

[0049] It should be noted that after the concrete is injected, the inlet 11 can be sealed by a precast plug to prevent the concrete from overflowing during the solidification process.

[0050] In some embodiments, such as Figures 1 to 3 As shown, each composite plate 5 also includes a limiting plate 6.

[0051] The limiting plate 6 is set on the outside of the composite plate 5 and is connected to the outer concrete layer 4 through the connecting structure 7, thereby restricting the composite plate 5 from moving outward and ensuring its position is stable under the pressure of concrete pouring.

[0052] In some embodiments, such as Figure 3 , Figure 4 and Figure 11 As shown, the connecting structure 7 includes a first alignment hole 71, a second alignment hole 72, a third alignment hole 73, and a connecting bolt 74.

[0053] The first alignment hole 71 is used to be opened on the wall surface and extends through the inner side of the wall in a direction perpendicular to the wall surface.

[0054] The second alignment hole 72 is formed on the insulation layer 2 and is coaxially arranged with the first alignment hole 71.

[0055] The third alignment hole 73 is formed on the precast plate and is coaxially arranged with the second alignment hole 72.

[0056] The connecting bolt 74 is inserted into the interconnected first alignment hole 71, second alignment hole 72 and third alignment hole 73, with its head abutting the outer side of the limiting plate 6 and its end extending into the inner side of the wall; the end of the connecting bolt 74 is threadedly connected to a support member 8 for abutting the inner side of the wall.

[0057] By adopting the above technical solution, the outer frame 1, insulation layer 2, outer concrete layer 4 are firmly connected to the original wall as a whole.

[0058] In some embodiments, such as Figure 4 , Figure 11 and Figure 12 As shown, the limiting plate 6 has a guide cylinder 61.

[0059] The guide cylinder 61 adopts a hollow straight cylinder structure. When the limiting plate 6 abuts against the outer side of the composite plate 5, the guide cylinder 61 passes through the third alignment hole 73, the second alignment hole 72 and the first alignment hole 71 to enter the inner side of the wall, so that part of the guide cylinder 61 is in the processing space.

[0060] The connecting bolt 74 is inserted into the guide tube 61, with its head abutting the outer side of the limiting plate 6 and its end extending into the inner side of the wall. The guide tube 61 provides precise insertion guidance and protection for the connecting bolt 74.

[0061] By adopting the above technical solution, the core function of the guide tube 61 is to combine with the solidification process of the inner concrete layer 3 to form an enhanced mechanical anchoring node, thereby significantly improving the overall structural strength.

[0062] Specifically, after the inner concrete is poured and solidified, the outer wall of the guide cylinder 61, which extends into the processing space, is tightly wrapped by the concrete, forming a strong mechanical interlock. This makes the guide cylinder 61 itself a rigid anchor deeply embedded in the inner concrete layer 3. When the connecting bolt 74 is subjected to tensile force, the force is transmitted to the guide cylinder 61 through the limiting plate 6 and evenly distributed through the large-area bonding interface between it and the inner concrete layer 3, which greatly enhances the pull-out bearing capacity and shear performance of the joint, optimizes the load transmission path from the outside to the inside, and effectively ensures the long-term structural integrity and stability between the various structural layers of the insulation wall panel.

[0063] In some embodiments, such as Figure 2 and Figure 12 As shown, the guide cylinder 61 is fixedly connected to the inner side of the limiting plate 6, and the limiting plate 6 has a through hole 62 that is coaxially connected to the guide cylinder 61.

[0064] The connecting bolt 74 is inserted into the through hole 62, with its head abutting the outer side of the limiting plate 6 and its end passing through the guide tube 61 and extending into the inner side of the wall.

[0065] By adopting the above technical solution, the guide cylinder 61 and the limiting plate 6 are prefabricated and connected to form a precise channel for the connecting bolt 74 to pass through, bringing about multi-layered synergistic benefits. The primary effect of this design is to achieve precise and convenient hole alignment and connection across multiple layers of structure (limiting plate 6, prefabricated panels, insulation layer 2, and wall). Specifically, during the factory prefabrication stage, the guide cylinder 61 and the limiting plate 6 can be precisely assembled to ensure that the through hole 62 and the inner hole of the guide cylinder 61 are strictly coaxial. During on-site installation, the entire limiting plate 6 assembly only needs to be placed in place, and the guide cylinder 61 on it can naturally pass through the prefabricated alignment holes of each layer on the prefabricated panels and insulation layer 2, and finally insert into the first alignment hole 71 on the wall, thereby automatically completing the alignment of all interlayer holes and completely eliminating the tedious work and accumulated errors of repeated on-site calibration layer by layer.

[0066] Furthermore, this design significantly improves the standardization and efficiency of construction. The limiting plate 6, guide cylinder 61, and connecting bolt 74 can be used as a prefabricated connection module, with quality control and partial pre-assembly performed in the factory. During on-site construction, workers only need to perform simple plug-in and tightening operations to complete the installation of a high-strength connection node, transforming complex multi-step, high-precision on-site assembly into rapid modular installation. This not only reduces the skill requirements for construction but also ensures the uniformity and reliability of the connection quality.

[0067] In some embodiments, such as Figure 3 , Figure 11 and Figure 12 As shown, the outer diameter of the shank of the connecting bolt 74 is equal to the inner diameter of the guide cylinder 61; this design ensures a tight fit between the two, effectively transmitting shear force. Specifically, this structure creates an efficient and reliable force transmission path.

[0068] After the connecting bolt 74 is inserted, its outer diameter is tightly fitted with the inner diameter of the guide cylinder 61, which allows for effective transmission of shear force between the bolt and the guide cylinder 61. When the wall system is subjected to thermal stress or external loads, the force acting on the outer concrete layer 4 can be directly and smoothly transmitted to the internal main wall through the mating surfaces of the limiting plate 6, the guide cylinder 61, and the connecting bolt 74, rather than relying entirely on the bonding force between the layers. This greatly enhances the shear and pull-out resistance of the overall structure and prevents interlayer delamination.

[0069] In some embodiments, such as Figure 4 and Figure 13 As shown, the support member 8 includes a bracket 81 and a mating nut 82.

[0070] The bracket 81 is fitted into the insertion portion of the connecting bolt 74 and has multiple legs 811 that abut against the inner side of the wall to distribute pressure.

[0071] The mating nut 82 is fixedly mounted on the bracket 81 and is threadedly connected to the connecting bolt 74; tightening the mating nut 82 will lock the connecting bolt 74 through the bracket 81.

[0072] By adopting the above technical solution, the design of the support member 8 aims to build a stable anchor end on the inner side of the wall to achieve reliable tensioning of the connection system and uniform load distribution.

[0073] Specifically, the bracket 81 forms surface contact with the inner side of the wall through its multiple legs 811. This design effectively disperses the concentrated compressive stress generated when the connecting bolts 74 are tightened to a larger area of ​​the wall, avoiding the risk of localized crushing. The mating nuts 82 fixed to the bracket 81 are threadedly connected to the connecting bolts 74, so that rotating the connecting bolts 74 can synchronously drive the bracket 81 to tighten inward, thereby generating the required preload within the wall interlayer.

[0074] The beneficial effects of this structure lie in achieving a balance between ease of installation and reliable connection. Firstly, the pre-assembly of the bracket 81 and the mating nut 82 simplifies on-site operations; construction workers only need to tighten the connecting bolt 74 inside the wall to complete the entire joint's fastening, eliminating the need for additional nut alignment and fixing in confined spaces. Secondly, the support structure composed of multiple legs 811 significantly increases the bearing area, ensuring the integrity of the inner surface of the wall at the connection point under long-term loads, preventing material damage due to stress concentration, and thus guaranteeing the long-term stability and durability of the overall connection joint.

[0075] In some embodiments, such as Figure 6 , Figure 7 and Figure 10 As shown, the outer periphery of the insulation layer 2 is provided with a slot 22, and the outer frame 1 is provided with a positioning hole 12 that communicates with the slot 22.

[0076] The building insulation wall panel also includes a limiting shaft 9; the limiting shaft 9 is inserted into the interconnected slot 22 and positioning hole 12, thereby limiting the movement of the insulation layer 2 relative to the outer frame 1 in the horizontal plane and ensuring that its position remains fixed during construction.

[0077] This application also provides a construction method for building insulation wall panels, which is based on the building insulation wall panels proposed in any of the foregoing claims and includes the following steps: A. Assemble the outer frame 1 and the insulation layer 2, and fix the outer frame 1 on the wall surface to form a processing space and an installation space; B. Place the single-layer precast panel into the installation space, so that the corresponding reserved hole 21 and guide hole 41 are connected to each other, and make the outer filling module 51 embedded in the guide hole 41 and the inner filling module 52 embedded in the reserved hole 21. C. Pour concrete into the processing space until the concrete level pushes the composite panel 5 outward, then stop pouring; D. Push the composite plate 5 inward to reset the outer filling module 51 to the embedded guide hole 41 and the inner filling module 52 to the embedded reserved hole 21; E. Wait for the concrete in the processing space to solidify, forming the corresponding part of the inner concrete layer 3; F. Repeat steps B to E until the outer concrete layer 4, which is composed of multiple layers of precast slabs, abuts against the inner top surface of the outer frame 1, and the inner concrete layer 3 is formed by the accumulation of multiple inner concrete layers 3 and abuts against the inner top surface of the outer frame 1.

[0078] The construction method provided in this application firstly combines and fixes the outer frame 1 and the insulation layer 2 to the wall, forming independent processing and installation spaces, thus creating the foundation for the separation of subsequent internal and external processes. Then, a bottom-up cyclical construction process is adopted: in each cycle, a layer of precast panels is placed in the installation space, and the inner filling module 52 and the outer filling module 51 are respectively embedded in the reserved holes 21 of the insulation layer 2 and the guide holes 41 of the panels; then, concrete is poured into the processing space until the concrete level rises to the height of the reserved holes 21 and pushes the composite panel 5 outward, at which point pouring is immediately stopped; then, the composite panel 5 is reset, and the concrete layer is allowed to solidify to form a partial inner concrete layer 3. This cycle is repeated until the precast panels are stacked layer by layer to complete the outer concrete layer 4, while the inner concrete layer 3 is simultaneously accumulated to the designed height.

[0079] The core of the aforementioned cyclical construction method lies in breaking down the high-risk operation of traditional one-time monolithic pouring into multiple low-height, controllable single-layer cycles. The principle is as follows: within each cycle unit, the alignment of the pre-drilled holes 21 and guide holes 41, and the embedding of the composite plate 5, structurally prepare for the connection between the inner concrete layer 3 and the outer concrete layer 4. During pouring, the displacement of the composite plate 5 by the concrete directly and visually indicates that the concrete layer has reached the preset full height and density, realizing the transformation of quality control from "experience-based judgment" to "physical signal feedback." Resetting the composite plate 5 and allowing it to solidify ensures the stable wrapping of the inner concrete layer 3 around the composite plate 5 at the connection point, laying the foundation for the final rigid mechanical anchoring. This layer-by-layer cyclical mode ensures that the construction process remains in a safe state of low height, easy observation, and timely intervention.

[0080] The construction method provided in this embodiment, compared with existing technologies, systematically reduces construction difficulty, improves quality control, and ensures the reliability of interlayer connections through a process design of "spatial separation, layered circulation, and displacement feedback." It completely avoids the risk of insulation board displacement caused by imbalance in the simultaneous pouring of inner and outer concrete in traditional processes, and transforms the concealed interlayer pouring state into a visually apparent physical signal, making construction quality monitorable and controllable. Simultaneously, layered construction ensures that each layer's connection interface is fully and densely encased in concrete, ultimately forming a uniform and reliable rigid connection system through the composite panel 5. This method has clear steps and is highly operable, significantly improving the construction efficiency, safety, and finished product reliability of building insulation wall panels while ensuring structural and thermal performance.
