Description

Technical Field

[0001] This invention relates to the field of building envelope structures, specifically to a structural insulation integrated firewall system with built-in vacuum insulation panels. Background Technology

[0002] Vacuum insulation panels are a new type of high-efficiency insulation material. Their thickness is less than 1 / 6 of that of traditional insulation materials under the same thermal resistance. They have been applied to the field of building exterior wall insulation due to their excellent flame-retardant and thermal insulation properties. However, when applied to thin-plaster exterior wall insulation systems, due to the limitations of their own structural form, they have exposed their shortcomings of being not puncture-resistant and easily damaged. After puncture causes local air leakage and failure of the panel, it will lead to condensation and mold growth in the room. The loss of vacuum degree will also cause a significant decrease in the insulation effect.

[0003] Building insulation and structural integration technology represents a revolution in traditional building exterior wall insulation technology. It integrates thermal insulation and energy-saving functions with wall enclosure functions, improving structural energy efficiency and fire resistance. Existing building exterior wall insulation systems mostly use materials such as extruded polystyrene boards and rock wool boards, which are thick, have limited thermal resistance, and the splicing gaps at the corners of the exterior walls are prone to becoming thermal bridges. Although vacuum insulation panels have extremely high thermal conductivity, their fragility and indivisibility in actual engineering pose great difficulties in transportation, construction, and corner placement, often leading to vacuum failure or large installation gaps that cause thermal bridges. To address this, we propose a structural insulation integrated firewall system with built-in vacuum insulation panels. Summary of the Invention

[0004] The purpose of this invention is to provide a structural insulation integrated fireproof system with a built-in vacuum insulation panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a structural insulation integrated firewall system with built-in vacuum insulation panels comprises, from the inside out: a base wall, a vacuum insulation layer arranged on the outside of the base wall, a protective box layer covering the vacuum insulation layer, a continuous fireproof layer located on the outside of the protective box layer, and a removable fireproof layer located on the outside of the continuous fireproof layer; wherein, the vacuum insulation layer includes a load-bearing frame, the interior of which is provided with several cavities for installing the vacuum insulation panels, the vacuum insulation layer is provided with removable protective boxes in high-risk areas, and the filling material inside the vacuum insulation layer has a compression allowance of 2-5mm.

[0006] Furthermore, the base wall includes a first wall and a second wall, and the vacuum insulation panels on one side of the first wall and the second wall are arranged in a staggered manner.

[0007] Furthermore, the high-risk areas of the vacuum insulation layer include corner areas, areas around door and window openings, areas where pipelines pass through, areas 0-1500mm from the ground, or areas easily accessible to personnel.

[0008] Furthermore, the detachable fireproof layer includes several impact-resistant fireproof boards, which are detachably installed outside the protective box in the high-risk area of ​​the vacuum insulation layer, and high-temperature resistant sealing strips or inorganic fireproof putty are provided at the joints of the impact-resistant fireproof boards.

[0009] Furthermore, the protective box is provided with thermal break gaskets around its perimeter, the outer wall of the vacuum insulation board is attached with elastic buffer strips, and a fire-resistant isolation gasket is provided between the outer side of the protective box and the continuous fireproof layer.

[0010] Furthermore, the protective box is made of metal sheet, inorganic fiber reinforced composite board or high-density refractory material.

[0011] Furthermore, the surface of the load-bearing frame is provided with a horizontal screw hole, and the surface of the screw hole is threaded with a connector extending horizontally towards the base wall.

[0012] Furthermore, the impact-resistant fireproof board is a calcium silicate board, a fiber-reinforced inorganic board, an aluminized zinc metal board, or a composite impact-resistant panel.

[0013] Furthermore, several temperature sensors are provided on the inner side of the load-bearing frame.

[0014] Furthermore, the load-bearing frame is provided with micro-humidification channels between several of the cavities.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this solution, by setting a protective box layer and a removable fireproof layer outside the vacuum insulation layer, and configuring an elastic buffer strip inside the protective box, the point load generated by construction, handling, knocking, positioning, etc. is effectively absorbed, avoiding local punctures or micro-cracks in the thin-walled vacuum insulation panel and extending its service life. 2. In this solution, detachable protective boxes are installed in impact-prone areas such as corners, around openings, and 0-1500mm areas, and covered with detachable impact-resistant fireproof boards. Damaged parts can be replaced individually without damaging the entire continuous fireproof layer, significantly reducing maintenance difficulty. 2. In this solution, a micro-humidification channel is set between the vacuum insulation panels to achieve low-speed moisture migration without forming air convection, avoiding moisture absorption by the edge seal and accumulation of moisture in the cavity, so that the thermal resistance remains stable for a long time. Temperature sensors or vacuum tags are arranged inside the protection box to monitor the risk of vacuum insulation panel failure in real time, so as to achieve point-to-point maintenance instead of large-area removal.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] A structurally integrated fireproof wall system with built-in vacuum insulation panels, such as Figure 1-6 As shown, from the inside out, it includes: a base wall 1, a vacuum insulation layer 2 arranged on the outside of the base wall 1, a protective box layer 3 covering the vacuum insulation layer 2, a continuous fireproof layer 4 located on the outside of the protective box layer 3, and a removable fireproof layer 5 located on the outside of the continuous fireproof layer 4; wherein, the vacuum insulation layer 2 includes a load-bearing frame 6, and the interior of the load-bearing frame 6 is provided with several cavities 8 for installing vacuum insulation panels 7. The vacuum insulation layer 2 is provided with a removable protective box 9 in high-risk areas. The filling material inside the vacuum insulation layer 2 has a compression allowance of 2-5mm to avoid long-term shear stress damage.

[0020] The base wall 1 includes a first wall and a second wall. The vacuum insulation panels 7 on one side of the first wall and the second wall are arranged in a staggered manner, so that the corner of one side panel corresponds to the middle position of the other side panel.

[0021] Understandably, because the vacuum insulation panel 7 is extremely thin, local point loads can cause punctures or micro-cracks, which can lead to the loss of vacuum. The large amount of handling, positioning, knocking, and fixing during construction is often the biggest source of risk. However, certain usage conditions such as long-term vibration, humidity, and secondary renovations can also cause damage. Therefore, high-risk areas of the vacuum insulation layer 2 include corner areas, around door and window openings, areas where pipelines pass through, areas close to the ground (0-1500mm), or areas that are easily accessible to people.

[0022] The detachable fireproof layer 5 includes several impact-resistant fireproof boards 10. These impact-resistant fireproof boards 10 are detachably installed outside the protective box 9 in the high-risk area of ​​the vacuum insulation layer 2. They can be installed and removed by buckles, locking plates, or screws. High-temperature resistant sealing strips or inorganic fireproof putty are installed at the joints of the impact-resistant fireproof boards 10.

[0023] Specifically, the protective box 9 is equipped with thermal break gaskets around its perimeter to prevent thermal bridge transfer, and the outer wall of the vacuum insulation board 7 is attached with elastic buffer strips to absorb mechanical impact energy. A fire-resistant isolation gasket is provided between the outer side of the protective box 9 and the continuous fireproof layer 4. The protective box 9 is made of metal sheet, inorganic fiber reinforced composite board or high-density fire-resistant material.

[0024] To enhance the connection between the load-bearing frame 6 and the base wall 1, a horizontal screw hole 11 is provided on the surface of the load-bearing frame 6. A connector 12 extending horizontally towards the base wall 1 is threaded onto the surface of the screw hole 11. During construction, anchoring holes matching the connector 12 are drilled on the base wall 1.

[0025] Among them, the impact-resistant fireproof board 10 is made of calcium silicate board, fiber-reinforced inorganic board, aluminum-zinc coated metal board or composite impact-resistant panel.

[0026] Understandably, the inner side of the load-bearing frame 6 is equipped with several temperature sensors or vacuum tags to ensure that problems can be quickly and locally replaced.

[0027] Among them, the load-bearing frame 6 has micro-humidification channels between several cavities 8, which provide a path for the release of water vapor with extremely low flow rate to the inside of the system without destroying the overall fireproof continuity or weakening the sealing plate protection effect, so that the inside will not accumulate moisture.

[0028] In this embodiment, it is understood that during construction, especially at the corner 1, the staggered joints are arranged on the first and second walls according to the design specifications. Corresponding anchoring holes are drilled according to the dimensions of the connector 12. The load-bearing frame 6 is aligned with the anchoring holes of the base wall 1 and fixed using the threaded connector 12. Several vacuum insulation panels 7 are implanted in the cavity 8, with a 2-5mm compression allowance to compensate for construction errors and reduce damage caused by long-term shear stress. During installation, the corner of panel A corresponds to the center of panel B between the first and second walls to improve stress resistance. To ensure a good seal, install the protective box 9 aligned with the outside of the vacuum insulation board 7, with thermal break gaskets laid around it and elastic buffer strips pasted on the inner wall. Install detachable protective boxes 9 in the 0-1500mm area around doors, windows, corners, and the ground, and install ordinary protective boxes in other locations. Set fire-resistant isolation gaskets outside the protective box layer 3, and then install the continuous fireproof layer 4. Use inorganic fireproof putty or high-temperature resistant sealing strips for the joints between the fireproof layers. In high-risk areas, fasten or screw the impact-resistant fireproof board 10 to the outside of the protective box 9, and set sealing strips at the joints to maintain the fire resistance continuity between the detachable parts and the continuous fireproof layer.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
