Description

Technical Field

[0001] This application relates to the technical field of building envelope structures, and in particular to a thermal insulation system for building envelope structures without thermal bridges. Background Technology

[0002] In the field of building construction, the building envelope serves as a crucial barrier between the building and its external environment, and its thermal insulation performance directly impacts the building's energy consumption, indoor thermal comfort, and lifespan. Currently, the most common building insulation walls on the market are mainly divided into two categories: monolithic cast-in-place insulation walls and panel-jointed insulation walls. Monolithic cast-in-place insulation walls suffer from drawbacks such as long construction cycles, high requirements for on-site working environments, and a high dependence on the technical skills of construction workers. Furthermore, once localized damage occurs, repairs are difficult and costly, making it difficult to meet the needs of large-scale, rapid construction. Therefore, panel-jointed insulation walls are more common.

[0003] Existing panel-type insulation walls mostly use simple flat butt joints or tongue-and-groove joints. Due to factors such as dimensional errors in the insulation panels themselves and insufficient control over splicing precision during construction, gaps easily appear at the joints. These gaps compromise the integrity of the insulation wall and become major channels for heat transfer. Secondly, the lack of effective temporary fixing and positioning devices during the construction of insulation walls results in poor construction safety and convenience. When building multi-layer insulation panels, construction workers usually need to use external scaffolding or temporary support structures to support and position the upper insulation panels, which not only increases the construction process and labor intensity but also poses a safety hazard of insulation panels slipping due to unstable temporary supports. Utility Model Content

[0004] To achieve efficient construction and effective thermal insulation, this application provides a thermal bridge-free thermal insulation system for building envelopes.

[0005] The technical solution for a thermal bridge-free insulation system for building envelope provided in this application is as follows: A thermal bridge-free insulation system for building envelope includes an exterior wall. Two sets of wall frames are symmetrically arranged on both sides of the outer surface of the exterior wall. The wall frames are fixedly connected to the exterior wall. An insulation wall is installed between the two sets of wall frames. Several sets of positioning strips for pressing the insulation wall are evenly installed from top to bottom on the outer end of the wall frames. The positioning strips are rotatably connected to the wall frames. A decorative panel is attached to the outer surface of the positioning strip. A locking device for locking the decorative panel is also installed on the outer end of the wall frames.

[0006] By adopting the above technical solution, symmetrical wall frames are installed on both sides of the wall, providing a stable support structure for the installation of the insulation wall and decorative panels. The wall frames are fixedly connected to the exterior wall, ensuring a firm bond between the entire system and the exterior wall. Positioning strips are rotatably mounted on the wall frames, facilitating the holding and adjustment of the insulation wall, ensuring that the insulation wall can be installed layer by layer from top to bottom during construction, and ensuring the stability of the insulation wall in later use. Decorative panels are fitted onto the outer side of the positioning strips, serving not only a decorative purpose but also further protecting the insulation wall. Locking devices are used to lock the decorative panels in place, preventing loosening and improving the stability and integrity of the system.

[0007] Optionally, the wall frame includes a wall panel, a side stop, and a limiting frame for installing locking components. The wall panel is attached to the outer side of the exterior wall and is fixedly connected to the exterior wall by bolts. One end of the side stop is connected to the wall panel, and the limiting frame is installed at the other end of the side stop. The wall panel, side stop, and limiting frame are integrally formed.

[0008] By adopting the above technical solution, the wall frame uses an integrated structure of wall panels, side supports, and limiting brackets, enhancing its overall strength and stability. The wall panels are bolted to the exterior wall, ensuring a secure connection between the wall frame and the exterior wall, and capable of supporting the weight of the insulation wall and decorative panels. The side supports facilitate better positioning and installation of the insulation wall, while the limiting brackets provide a suitable location for the installation of locking components, allowing for quick and easy engagement and fixation of the decorative panels.

[0009] Optionally, the side stop includes a side plate, a connecting ear plate, and a connecting shaft. The connecting ear plate is configured in two sets, and the two sets of connecting ear plates are integrally formed and disposed at the upper and lower ends of the side plate. The connecting shaft is vertically installed between the two sets of connecting ear plates.

[0010] By adopting the above technical solution, the side plate of the side stop provides support for the connecting ear plate and the connecting shaft. The design of the connecting ear plate and the connecting shaft allows the positioning strip to rotate flexibly. The connecting shaft is vertically installed between the two sets of connecting ear plates, ensuring the stability of the positioning strip's rotation, facilitating the pressing and adjustment of the insulation wall, and improving installation efficiency.

[0011] Optionally, the limiting frame includes an inclined plate portion and a concave retaining shell, the concave retaining shell being disposed at the outer end of the side stop seat, and the concave retaining shell being fixedly connected to the side stop seat through the inclined plate portion.

[0012] By adopting the above technical solution, the inclined plate of the limiting frame serves as a transitional connection, making the connection between the concave retaining shell and the side stop more stable. The concave retaining shell provides a specific slot for the installation of the locking component, facilitating the insertion of the elastic retaining strip and effectively locking the decorative panel to prevent displacement during use.

[0013] Optionally, the positioning strip includes a horizontal pressure plate and a sleeve that cooperates with the connecting shaft. The sleeve is installed at one end of the horizontal pressure plate and is integrally formed with the horizontal pressure plate.

[0014] By adopting the above technical solution, the horizontal pressure plate of the positioning strip is used to hold the insulation wall, and the sleeve cooperates with the connecting shaft, allowing the positioning strip to rotate around the connecting shaft. The one-piece molded structure ensures the strength and stability of the positioning strip, ensuring that it can provide sufficient pressure when pressing against the insulation wall and preventing the insulation wall from loosening.

[0015] Optionally, the end of the transverse pressure plate away from the sleeve is provided with a plug-in slot, and a locking block is detachably installed in the plug-in slot. The locking block includes a middle base shell and a side plate. The side plate is integrally formed and disposed on both sides of the middle base shell. An operating handle is fixedly installed in the middle base shell.

[0016] By adopting the above technical solution, the design of the interlocking slots and locking blocks on the horizontal pressure plate facilitates the locking of the positioning strips. After the positioning strips at both ends are flipped to the same plane, the horizontal pressure plate is installed to lock them in place, thereby securing the rows of insulation walls. The side plates of the locking blocks can snap into the interlocking slots, increasing the stability of the positioning strips. The operating handle makes the installation and removal of the locking blocks more convenient, facilitating construction and maintenance.

[0017] Optionally, the locking element includes an outer pressure plate and an elastic locking strip that cooperates with the concave locking housing, the elastic locking strip being fixedly installed on the inner side of the outer pressure plate.

[0018] By adopting the above technical solution, the outer pressure plate of the locking component is used to press the decorative panel, and the elastic strip cooperates with the concave retainer, utilizing the elastic deformation of the elastic strip to achieve a tight engagement with the concave retainer. This design makes the installation and removal of the locking component convenient, while effectively locking the decorative panel and ensuring its secure installation.

[0019] Optionally, the insulation wall is composed of several sets of insulation panels spliced ​​together, and the cross-section of the insulation panels is set as a bent structure.

[0020] By adopting the above technical solution, the insulated wall is composed of several sets of insulated panels spliced ​​together, and the cross-section of the insulated panels is designed with a bent structure to facilitate splicing between horizontally adjacent insulated panels. This splicing method makes the installation of the insulated wall more convenient, while ensuring the integrity and airtightness of the insulated wall, reducing heat loss, and improving the insulation effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This application uses spliced ​​insulation panels to form the insulation wall, and the panel cross-section has a bent structure, ensuring the integrity and sealing of the insulation wall, reducing heat loss, and improving the insulation performance of the building envelope. Simultaneously, by setting rotatable positioning strips, stable layer-by-layer construction is ensured during insulation wall building. After one layer is built, the positioning strips at both ends of that layer are flipped and attached to the insulation wall, and then locked with locking blocks before building the next layer, making the process safer and more convenient. Furthermore, the decorative panels can be locked using two sets of locking components, and the installation and disassembly of the locking blocks and components are convenient, improving construction efficiency.

Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a thermal bridge-free insulation system for building envelope structures. (Refer to...) Figure 1 , Figure 2 and Figure 3A thermal bridge-free thermal insulation system for building envelope includes an exterior wall 1. Two sets of wall frames 2 are symmetrically arranged on both sides of the exterior wall 1, and the wall frames 2 are fixedly connected to the exterior wall 1. An insulated wall 6 is installed between the two sets of wall frames 2. Several sets of positioning strips 3, which hold the insulated wall 6, are evenly installed from top to bottom on the outer ends of the wall frames 2. The positioning strips 3 are rotatably connected to the wall frames 2. A decorative panel 4 is attached to the outer surface of the positioning strips 3. Locking devices 5 for locking the decorative panel 4 are also installed on the outer ends of the wall frames 2. The symmetrical arrangement of wall frames 2 on both sides of the wall provides a stable support structure for the installation of the insulated wall 6 and the decorative panel 4. The fixed connection between the wall frames 2 and the exterior wall 1 ensures a firm bond between the entire system and the exterior wall 1. The positioning strips 3 are rotatably installed on the wall frames 2, facilitating the holding and adjustment of the insulated wall 6, ensuring that the insulated wall 6 can be installed layer by layer from top to bottom during construction, and ensuring the stability of the insulated wall 6 in later use. Decorative panel 4 is fitted onto the outer side of positioning strip 3, serving not only a decorative purpose but also further protecting the insulation wall 6. Locking element 5 is used to secure decorative panel 4, preventing loosening and improving the system's stability and integrity. This structural design effectively avoids thermal bridging and enhances the thermal insulation performance of the building envelope.

[0031] Reference Figure 3The wall frame 2 includes a wall panel 21, side stops 22, and a limiting bracket 23 for installing the locking component 5. The wall panel 21 is fitted onto the outer surface of the exterior wall 1 and is fixedly connected to the exterior wall 1 by bolts. One end of the side stop 22 is connected to the wall panel 21, and the limiting bracket 23 is installed at the other end of the side stop 22. The wall panel 21, side stop 22, and limiting bracket 23 are integrally formed. The wall frame 2 adopts an integrally formed structure of the wall panel 21, side stop 22, and limiting bracket 23, which enhances the overall strength and stability of the wall frame 2. The wall panel 21 is fixedly connected to the exterior wall 1 by bolts, ensuring the firmness of the connection between the wall frame 2 and the exterior wall 1, and is able to bear the weight of the insulation wall 6 and the decorative panel 4. The side stop 22 is set to facilitate better positioning and laying of the insulation wall 6, while the limiting bracket 23 is set to provide a suitable position for the installation of the locking component 5, so that the locking component 5 can quickly engage and fix the decorative panel 4. The side stop 22 includes a side plate portion 221, connecting ear plates 222, and a connecting shaft 223. Two sets of connecting ear plates 222 are integrally formed at the upper and lower ends of the side plate portion 221. The connecting shaft 223 is vertically installed between the two sets of connecting ear plates 222. The side plate portion 221 of the side stop 22 provides support for the connecting ear plates 222 and the connecting shaft 223. The design of the connecting ear plates 222 and the connecting shaft 223 allows the positioning pressure strip 3 to rotate flexibly. The vertical installation of the connecting shaft 223 between the two sets of connecting ear plates 222 ensures the stability of the rotation of the positioning pressure strip 3, facilitates the pressing and adjustment of the insulation wall 6, and improves installation efficiency. The limiting frame 23 includes an inclined plate portion 231 and a concave retainer 232. The concave retainer 232 is located at the outer end of the side stop 22 and is fixedly connected to the side stop 22 through the inclined plate portion 231. The inclined plate 231 of the limiting bracket 23 serves as a transition connection, making the connection between the concave retaining shell 232 and the side stop 22 more stable. The concave retaining shell 232 provides a specific slot for the installation of the locking member 5, which facilitates the insertion of the elastic retaining strip 52, effectively locking the decorative panel 4 and preventing the decorative panel 4 from shifting during use.

[0032] Reference Figure 4 , Figure 5 and Figure 6The positioning strip 3 includes a horizontal pressure plate 31 and a sleeve 32 that cooperates with the connecting shaft 223. The sleeve 32 is installed at one end of the horizontal pressure plate 31 and is integrally formed with the horizontal pressure plate 31. The horizontal pressure plate 31 of the positioning strip 3 is used to press the insulation wall 6, and the sleeve 32 cooperates with the connecting shaft 223, so that the positioning strip 3 can rotate around the connecting shaft 223. The integrally formed structure ensures the strength and stability of the positioning strip 3, ensuring that it can provide sufficient pressure when pressing the insulation wall 6 and prevent the insulation wall 6 from loosening. The end of the horizontal pressure plate 31 away from the sleeve 32 is provided with a plug-in slot 311. A locking block 33 is detachably installed in the plug-in slot 311. The locking block 33 includes a middle base shell 331 and a side plate 332. The side plate 332 is integrally formed on both sides of the middle base shell 331. An operating handle 333 is fixedly installed in the middle base shell 331. The design of the insertion slot 311 and locking block 33 on the horizontal pressure plate 31 facilitates locking the positioning pressure strip 3. After the positioning pressure strips 3 at both ends are flipped to the same plane, the horizontal pressure plate 31 is installed to lock the positioning pressure strips 3 at both ends, thereby pressing and fixing the rows of insulation walls 6. The side plate 332 of the locking block 33 can be inserted into the insertion slot 311, increasing the stability of the positioning pressure strip 3. The operating handle 333 makes the installation and removal of the locking block 33 more convenient, facilitating construction and maintenance.

[0033] Reference Figure 1 and Figure 2 The locking component 5 includes an outer pressure plate 51 and an elastic locking strip 52 that cooperates with the concave retaining shell 232. The elastic locking strip 52 is fixedly installed on the inner side of the outer pressure plate 51. The outer pressure plate 51 of the locking component 5 is used to press the decorative panel 4, and the elastic locking strip 52 cooperates with the concave retaining shell 232. The elastic deformation of the elastic locking strip 52 achieves a tight engagement with the concave retaining shell 232. This design makes the installation and removal of the locking component 5 convenient, and at the same time can effectively lock the decorative panel 4, ensuring that the decorative panel 4 is firmly installed.

[0034] Reference Figure 1 The insulation wall 6 is composed of several sets of insulation panels spliced ​​together, with the cross-section of each panel featuring a bent structure. This styling facilitates the splicing of adjacent horizontally aligned insulation panels. This splicing method makes the installation of the insulation wall 6 more convenient, while ensuring its integrity and airtightness, reducing heat loss, and improving insulation performance.

[0035] The implementation principle of the thermal bridging-free insulation system for building envelope structure according to this application embodiment is as follows: During actual installation, the wall frame 2 is installed by attaching the wall panel 21 to the outer side of the exterior wall 1, and using expansion bolts to fix the wall panel 21 to the exterior wall 1 to ensure a firm connection. After installation, the verticality and horizontality of the wall frame 2 are checked to ensure that they meet the installation requirements. Polystyrene foam insulation board is selected as the insulation board, and the insulation boards are spliced ​​according to the design requirements, with horizontally adjacent insulation boards spliced ​​together. After splicing one layer, the positioning strip 3 of the corresponding height is flipped over, and two sets of positioning strips 3 of the same height are locked by locking blocks 33. Then, the insulation wall 6 on one side is continued to be built until the insulation wall 6 is completely built. At this time, the positioning strip 3 is also completely installed, so that a beautiful and durable PVC decorative board 4 can be selected and attached to the outer side of the positioning strip 3. During the installation process, attention should be paid to the splicing and alignment of the decorative board 4 to ensure that its surface is flat. Finally, align the elastic clip 52 of the locking component 5 with the concave retaining shell 232 of the limiting bracket 23, and press the outer pressure plate 51 firmly to make the elastic clip 52 engage in the concave retaining shell 232, thereby locking both ends of the decorative panel 4. Check the installation of the locking component 5 to ensure that the decorative panel 4 is securely installed without any looseness.
