Description

Technical Field

[0001] This application relates to the field of building exterior wall insulation, and in particular to a passive low-energy building insulation system. Background Technology

[0002] Buildings provide a suitable environment for human production and life. In order to enhance the heat insulation effect of the building's exterior walls, reduce heat conduction between the interior and exterior of the building, and thus enhance the building's thermal insulation performance in order to save energy, the exterior walls of buildings are covered with exterior wall insulation materials.

[0003] Exterior wall insulation boards are a common type of exterior wall insulation material. They need to possess excellent thermal insulation performance, as well as low weight and excellent fire resistance to reduce the building's load and safety hazards. For ease of construction and transportation, factory-produced exterior wall insulation boards are small in size and require transport to the site by truck or other means. The boards are then spliced ​​and installed onto the building's exterior wall, typically using mortar to bond them to the facade. Gaps exist between adjacent insulation boards, penetrating the insulation layer. To minimize the impact of these gaps on the overall insulation performance, sealant is applied to the gaps during installation.

[0004] Regarding the aforementioned technologies, when installing exterior wall insulation panels, sealant needs to be applied to each contact surface of adjacent exterior wall insulation panels, which affects the installation efficiency of the exterior wall insulation panels. Summary of the Invention

[0005] To improve the installation efficiency of external wall insulation panels, this application provides a passive low-energy building insulation system.

[0006] This application provides a passive low-energy building insulation system, which adopts the following technical solution:

[0007] A passive low-energy building insulation system includes a first splicing plate and a second splicing plate for heat insulation. Both the first and second splicing plates are installed on the exterior facade of the building. The first and second splicing plates are alternately installed in both vertical and horizontal directions and abut against each other. A receiving groove is provided on the side of the first splicing plate, and sealant is provided in the receiving groove. A sealing film is provided at the opening of the receiving groove to prevent the sealant from leaking. A blade is provided on the second splicing plate for cutting the sealing film.

[0008] By adopting the above technical solution, when installing the first and second splicing panels on the building facade, the blade on the second splicing panel will slide through the sealing film of the corresponding part on the adjacent first splicing panel, and the sealant in the receiving groove will flow out into the gap between the first and second splicing panels, sealing the gap between the first and second splicing panels. This can realize automatic application of sealant, eliminating the need for workers to apply it separately, reducing installation steps, and helping to improve the installation efficiency of the exterior wall insulation panels.

[0009] Optionally, the receiving groove is provided with an airbag made of elastic material, and the sealant is placed in the airbag. When the sealing film seals the receiving groove, the airbag is in an inflated state.

[0010] By employing the above technical solution, the sealant's efficiency is low when it relies solely on natural flow to enter the gap between the first and second splicing panels after the sealing film is damaged by the blade. By inflating an airbag for storing the sealant, the airbag contracts when the sealing film ruptures, reducing its internal space and thus promoting the sealant's drainage into the gap between the first and second splicing panels. This helps improve the sealing effect and reduces the impact of the gap on the overall thermal insulation performance of the external wall insulation board.

[0011] Optionally, the second splicing plate has an adhesive groove on its side, and when the first splicing plate and the second splicing plate abut against each other, the adhesive groove is connected to the receiving groove.

[0012] By adopting the above technical solution, the adjacent first and second splicing plates are in abutting position, and the gap between the first and second splicing plates is small, making it difficult for the sealant to flow smoothly within the gap. The adhesive groove, which communicates with the receiving groove, provides a smooth flow path for the sealant, helping to improve the sealing effect.

[0013] Optionally, the adhesive groove is filled with absorbent cotton for absorbing sealant.

[0014] By adopting the above technical solution, both the first and second splicing plates are set on the vertically oriented exterior facade of the building. Due to gravity, the sealant in the vertically oriented adhesive groove flows unevenly, affecting the sealing effect. The addition of absorbent cotton, which has a siphon effect on the liquid sealant, helps to distribute the sealant more evenly within the adhesive groove, thus improving the sealing effect.

[0015] Optionally, a connecting rod is connected to the side of the second splicing plate, and a connecting groove for accommodating the connecting rod is provided on the first splicing plate. A snap-fit ​​block is connected to the end of the connecting rod away from the second splicing plate, and a snap-fit ​​groove for the snap-fit ​​block is provided on the first splicing plate.

[0016] By adopting the above technical solution, both the first and second splicing panels are connected to the building facade using cement mortar. Adjacent first and second splicing panels abut against each other and are bonded with sealant. The sealant improves the sealing of the connection between the first and second splicing panels, but the connection strength is low, and the tensile strength between adjacent first and second splicing panels is poor. The second splicing panel is equipped with connecting rods and locking blocks, while the first splicing panel is equipped with connecting grooves and locking grooves. When the first and second splicing panels abut against each other, the locking blocks are embedded in the locking grooves, which helps to improve the tensile strength between the first and second splicing panels.

[0017] Optionally, a sliding groove is provided on the side wall of the snap-fit ​​groove, and a slider is slidably connected in the sliding groove. A first elastic element is connected between the bottom wall of the sliding groove and the slider. When the first elastic element is in its natural state, the end of the slider away from the bottom wall of the sliding groove extends into the snap-fit ​​groove. A locking groove adapted to the slider is provided on the snap-fit ​​block. When the snap-fit ​​block is fully embedded in the snap-fit ​​groove, the slider is embedded in the locking groove.

[0018] By adopting the above technical solution, after the snap-fit ​​block is embedded in the snap-fit ​​groove, the slider is embedded in the locking groove, which can prevent the snap-fit ​​block from coming out of the snap-fit ​​groove, thereby helping to improve the connection strength between the first splicing plate and the second splicing plate.

[0019] Optionally, a tightening groove is provided on the side of the second splicing plate, and the connecting rod is slidably connected in the tightening groove. A second elastic element is connected between the bottom wall of the tightening groove and the connecting rod. When the snap-fit ​​block is embedded in the snap-fit ​​groove, the second elastic element is in a stretched state.

[0020] By adopting the above technical solution, when the snap-fit ​​block is embedded in the snap-fit ​​groove, the second elastic element is in a stretched state and has a tendency to contract. The second elastic element pulls the bottom wall of the tightening groove and the connecting rod at both ends, so that the snap-fit ​​block has a tendency to move towards the bottom wall of the tightening groove, thereby making the adjacent first splice plate and the second splice plate more tightly abut against each other, which helps to improve the sealing effect between the first splice plate and the second splice plate.

[0021] Optionally, the locking block has a limiting groove, and a limiting block is provided in the limiting groove. A pin is slidably connected to the limiting block to prevent the limiting block from disengaging from the limiting groove. The end of the pin away from the locking block is located in the locking groove. The locking block has a release groove adapted to the locking block. The release groove is connected to the end of the limiting groove away from the connecting rod. A third elastic element is connected between the locking block and the bottom wall of the tightening groove. When the locking block is located in the limiting groove, the third elastic element is in a compressed state, and the second elastic element is in a stretched state. The part of the connecting rod outside the connecting groove is the same length as the connecting groove. When the locking block is located in the release groove, the connecting rod has a tendency to slide closer to the bottom of the connecting groove.

[0022] By adopting the above technical solution, before the snap-fit ​​block is embedded into the snap-fit ​​slot, the operator needs to pull the snap-fit ​​block outward to align it with the corresponding snap-fit ​​slot before embedding it into the slot. However, the second splicing plate often has multiple snap-fit ​​blocks on each side, making it difficult for a single operator to operate and requiring multiple people to cooperate, resulting in significant manpower consumption. By setting a limiting block, before the first and second splicing plates are connected, the limiting block is snapped into the limiting slot by a pin block and locking groove. The third elastic element is in a compressed state, and the second elastic element is in a stretched state. Furthermore, the portion of the connecting rod outside the connecting groove is the same length as the connecting groove. This eliminates the need for the operator to pull the snap-fit ​​block outward individually, helping to save manpower.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When workers install the first and second splicing panels on the exterior of the building, the first and second splicing panels are neatly aligned. The blade on the second splicing panel will cut through the sealing film of the corresponding part on the adjacent first splicing panel, and the sealant in the receiving groove will flow out and enter the gap between the first and second splicing panels to fill and seal the gap. The sealant can be automatically applied at the same time during installation, reducing the installation steps and helping to improve the installation efficiency of the exterior wall insulation panels.

[0025] 2. After the blade breaks the corresponding sealing membrane, the sealant can only flow into the gap between the first and second splicing plates by natural flow. The flow efficiency is low and it is not conducive to the filling and application of the sealant. An air bladder is set in the receiving groove. When the sealing membrane is intact, the air bladder is inflated. When the sealing membrane is broken, the air bladder contracts, reducing its internal space and squeezing the sealant out and into the gap between the first and second splicing plates, which helps to enhance the sealing effect.

Detailed Implementation

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a passive low-energy building insulation system.

[0034] Reference Figure 1 and Figure 2 A passive low-energy building insulation system includes a first splicing plate 1 and a second splicing plate 2. Both the first splicing plate 1 and the second splicing plate 2 are rectangular panels of the same size and are made of building insulation material. During installation, both the first splicing plate 1 and the second splicing plate 2 are bonded to the exterior facade of the building using cement mortar. In both horizontal and vertical directions, the first splicing plate 1 and the second splicing plate 2 are alternately abutted against each other, covering the exterior facade of the building. The surfaces of the first splicing plate 1 and the second splicing plate 2 perpendicular to the exterior facade of the building are called side panels. A receiving groove 11 is opened on the side panel of the first splicing plate 1, and sealant is filled into the receiving groove 11. A sealing membrane 12 is placed at the opening of the receiving groove 11 to seal the opening of the receiving groove 11. The second splicing plate 2 is provided with blades 21 corresponding to the sealing membranes 12. When installing the first splicing panel 1 and the second splicing panel 2 on the building facade, the blade 21 on the second splicing panel 2 coincides with the corresponding part of the sealing film 12 on the adjacent first splicing panel 1. The blade 21 cuts through the sealing film 12, and the sealant in the receiving groove 11 flows out and enters the gap between the first splicing panel 1 and the second splicing panel 2, sealing the gap. The sealant is automatically applied during the installation process, eliminating the need for workers to apply it separately, reducing the number of steps and helping to improve the installation efficiency of the exterior wall insulation panel.

[0035] Reference Figure 1 and Figure 2After the sealing membrane 12 is damaged by the blade 21, the sealant can only flow naturally into the gap between the first splicing plate 1 and the second splicing plate 2, which is inefficient. An air bladder 111 is installed inside the receiving groove 11. The air bladder 111 is made of soft rubber, and its opening is connected to the opening of the receiving groove 11. The sealing membrane 12 seals the receiving groove 11, and the sealant is filled into the air bladder 111, causing it to inflate. When the sealing membrane 12 ruptures, the air bladder 111 contracts, reducing its internal space and providing force for the sealant to be extruded. This forces the sealant to be discharged and enter the gap between the first splicing plate 1 and the second splicing plate 2, improving the sealing effect and reducing the impact of the gap on the overall thermal insulation effect of the external wall insulation board.

[0036] Reference Figure 2 and Figure 3 To ensure the overall thermal insulation effect of the exterior wall insulation board, the adjacent first splice panel 1 and second splice panel 2 must be in a tight abutment during installation. A small gap between them would prevent the sealant from flowing smoothly within the gap. An adhesive groove 22 is provided on the side of the second splice panel 2, extending along its length. After the first splice panel 1 and second splice panel 2 are in contact, the adhesive groove 22 connects with the receiving groove 11, allowing sealant from the receiving groove 11 to flow smoothly into the adhesive groove 22, thus improving the sealing effect.

[0037] Reference Figure 2 and Figure 3 Both the first splicing plate 1 and the second splicing plate 2 are installed on the vertically oriented exterior facade of the building. Due to gravity, the sealant tends to flow towards the lower parts of the structure, making it difficult for the sealant to be evenly distributed in the gaps and adhesive grooves 22, thus affecting the sealing effect. Absorbent cotton 221 is filled into the adhesive grooves 22. The absorbent cotton 221 has a siphon effect on the liquid sealant, allowing the sealant to overcome gravity and be more evenly distributed in the adhesive grooves 22 and gaps, thus improving the sealing effect.

[0038] Reference Figure 2 and Figure 3Both the first splicing panel 1 and the second splicing panel 2 are bonded to the exterior of the building using cement mortar. Adjacent first splicing panels 1 and 2 are bonded together using sealant. While the sealant helps improve the sealing of the connection points, it has low tensile strength. After being exposed to external environmental influences, the first splicing panels 1 and 2 are prone to cracking at the joints, affecting the sealing and insulation effect. A connecting rod 23 is provided on the side of the second splicing panel 2. A corresponding and compatible connecting groove 13 is provided on the first splicing panel 1. A snap-fit ​​block 24 is connected to the end of the connecting rod 23 away from the second splicing panel 2. A snap-fit ​​groove 14, compatible with the snap-fit ​​block 24, is provided on the first splicing panel 1 at a corresponding position. When the first splicing plate 1 and the second splicing plate 2 come into contact, the locking block 24 is embedded in the locking groove 14, which can effectively prevent the first splicing plate 1 from separating from the second splicing plate 2, thereby improving the tensile strength between the first splicing plate 1 and the second splicing plate 2.

[0039] Reference Figure 4 and Figure 5 A sliding groove 141 is formed on the side wall of the snap-fit ​​groove 14. A slider 142 is slidably connected in the sliding groove 141. A first elastic element 143 is connected between the bottom wall of the sliding groove 141 and the slider 142. The first elastic element 143 is made of spring. When the first elastic element 143 is in its natural state, the end of the slider 142 away from the bottom wall of the sliding groove 141 extends into the snap-fit ​​groove 14. A locking groove 241 adapted to the slider 142 is formed on the snap-fit ​​block 24. When the snap-fit ​​block 24 is fully embedded in the snap-fit ​​groove 14, the slider 142 is embedded in the locking groove 241, which can prevent the snap-fit ​​block 24 from coming out of the snap-fit ​​groove 14 and help improve the connection strength between the first splicing plate 1 and the second splicing plate 2 in the direction perpendicular to the building facade.

[0040] Reference Figure 4 and Figure 5 A tightening groove 25, corresponding to the connecting rod 23, is formed on the side of the second splicing plate 2. The connecting rod 23 is slidably connected to the corresponding tightening groove 25. A second elastic element 251, made of spring, connects the bottom wall of the tightening groove 25 and the connecting rod 23. When the second elastic element 251 is in its natural state, the portion of the connecting rod 23 outside the tightening groove 25 is smaller than the length of the connecting groove 13. Before the snap-fit ​​block 24 is inserted into the snap-fit ​​groove 14, the second elastic element 251 needs to be stretched. Therefore, when the snap-fit ​​block 24 is inserted into the snap-fit ​​groove 14, the second elastic element 251 has a tendency to contract, causing the snap-fit ​​block 24 to move towards the bottom wall of the tightening groove 25. This helps to make the adjacent first splicing plate 1 and second splicing plate 2 fit more tightly, thus improving the sealing and heat insulation effect between the first splicing plate 1 and the second splicing plate 2.

[0041] Reference Figure 4 and Figure 5Before the snap-fit ​​block 24 is inserted into the snap-fit ​​groove 14, the second elastic element 251 is in its natural state. The part of the connecting rod 23 outside the tightening groove 25 is shorter than the length of the connecting groove 13. Workers need to pull the snap-fit ​​block 24 outwards to align it with the corresponding snap-fit ​​groove 14. However, multiple snap-fit ​​blocks 24 are often provided on each side of the second splicing plate 2, making it difficult for a single worker to operate. Multiple workers are needed to cooperate in the installation at height, which is labor-intensive and difficult to implement. A limiting groove 242 and a release groove 244 are provided within the snap-fit ​​block 24. The release groove 244 is connected to the end of the limiting groove 242 opposite to the connecting rod 23. A limiting block 243 is provided within the limiting groove 242, and the limiting block 243 can slide between the limiting groove 242 and the release groove 244. In the initial state, the limiting block 243 is positioned within the limiting groove 242. A third elastic element 252 is connected between the snap-fit ​​block 24 and the bottom wall of the tightening groove 25. When the snap-fit ​​block 24 is located in the limiting groove 242, the third elastic element 252 is in a compressed state, and the second elastic element 251 is in a stretched state. At this time, the part of the connecting rod 23 located outside the connecting groove 13 is equal in length to the connecting groove 13. A pin 2431 for preventing the limiting block 243 from disengaging from the limiting groove 242 is slidably connected to the limiting block 243. The end of the pin 2431 facing away from the snap-fit ​​block 24 is located in the locking groove 241. When the snap-fit ​​block 24 is inserted into the snap-fit ​​groove 14, the slider 142 enters the locking groove 241 and pushes out the pin block 2431. The limiting block 243 enters the release groove 244. The third elastic element 252 extends and returns to its natural state. The second elastic element 251 remains extended and provides tension. The connecting rod 23 has a tendency to slide towards the bottom of the connecting groove 13. There is no need for the operator to pull the snap-fit ​​block 24 outwards, which helps to save manpower.

[0042] The implementation principle of a passive low-energy building insulation system according to an embodiment of this application is as follows: When installing the first splicing plate 1 and the second splicing plate 2 on the exterior facade of the building, the blade 21 on the second splicing plate 2 will slide and break the sealing film 12 at the corresponding position, and the sealant in the receiving groove 11 will flow out and enter the gap between the first splicing plate 1 and the second splicing plate 2, sealing and filling the gap, realizing the automatic application of sealant, eliminating the need for workers to apply it separately, reducing installation steps, and helping to improve the installation efficiency of the exterior wall insulation board.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
