[0027] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.
[0028] refer to Figure 1 and Figure 2 The curtain wall high-efficiency insulation system of the present application includes a target wall 1, a curtain wall unit 2 and an end sealing plate 3; wherein, the curtain wall unit 2 is arranged on one side of the target wall 1, the end sealing plate 3 is arranged at the end of the target wall 1 and connected to the curtain wall unit 2, and a functional space 4 is provided between the target wall 1, the curtain wall unit 2 and the end sealing plate 3.
[0029] During the specific implementation process, the functional space 4 is provided with a first longitudinal plate 5 and a second longitudinal plate 6 parallel to the outer wall of the target wall 1, and a fire-resistant transverse plate 7 perpendicular to the first longitudinal plate 5 and the second longitudinal plate 6. The structural combination of the first longitudinal plate 5, the second longitudinal plate 6 and the fire-resistant transverse plate 7 divides the functional space 4.
[0030] Specifically, the first longitudinal plate 5 and the fire-resistant transverse plate 7 divide the functional space 4 into a fireproof space 8, the first longitudinal plate 5 and the second longitudinal plate 6 divide the functional space 4 into an insulation space 9, and the fire-resistant transverse plate 7 and the second longitudinal plate 6 divide the functional space 4 into a buffer space 12.
[0031] Among them, the fireproof space 8 is filled with a fireproof material layer 10 connecting the target wall 1 and the first longitudinal plate 5, the insulation space 9 is filled with a insulation material layer 11 connecting the first longitudinal plate 5 and the second longitudinal plate 6, and the buffer space 12 has no filler, which maintains a set distance between the target wall 1 and the insulation space 9.
[0032] The curtain wall high-efficiency insulation system of the present application utilizes the distance between the target wall 1 and the curtain wall unit 2 to design a fireproof space 8, an insulation space 9 and a buffer space 12. The fireproof space 8 blocks the combustion connection between the target wall 1 and the curtain wall unit 2 through the fireproof material layer 10, thereby ensuring the safety of the curtain wall application. The insulation space 9 provides an efficient insulation measure for the curtain wall application through the clamping of the first longitudinal plate 5 and the second longitudinal plate 6 and the insulation material layer 11, and the buffer space 12 controls the distance between the target wall 1 and the insulation space 9. While ensuring the insulation effect, it blocks the direct connection between the target wall 1 and the curtain wall unit 2, further ensuring the safety of the curtain wall application.
[0033] It should be noted that the end sealing plate 3 is connected to an auxiliary horizontal plate 18, which is vertically connected to the target wall 1 and the first longitudinal plate 5. The outer wall of the target wall 1, the first longitudinal plate 5, the fire-resistant horizontal plate 7 and the auxiliary horizontal plate 18 enclose the fireproof space 8.
[0034] Furthermore, the fire-resistant transverse plate 7 can be connected to the first longitudinal plate 5 and the second longitudinal plate 6 respectively, thereby enclosing the insulation space 9 , and then the outer wall of the target wall 1 , the second longitudinal plate 6 and the fire-resistant transverse plate 7 enclose the buffer space 12 .
[0035] It is understandable that the first longitudinal plate 5 and the second longitudinal plate 6 are parallel to the outer wall of the target wall 1 , that is, the first longitudinal plate 5 and the second longitudinal plate 6 can extend along the arrangement of the tempered glass of the curtain wall unit 2 to ensure the thermal insulation effect.
[0036] Among them, in the direction perpendicular to the target wall 1, the sum of the lengths of the buffer space 12 and the insulation space 9 is equal to the length of the fireproof space 8, so as to make full use of the functional space 4 and maximize the fire prevention and insulation effects of the curtain wall system. The direction perpendicular to the target wall 1 is the extension direction of the two ends of the auxiliary horizontal plate 18 or the fire-resistant horizontal plate 7.
[0037] In one embodiment, combined Figure 2 and Figure 3 The fireproof material layer 10 includes at least one of a rock wool layer, a glass fiber layer, an aluminum silicate fiber layer, an expanded vermiculite layer or an expanded perlite layer.
[0038] Preferably, the fireproof material layer 10 is a rock wool layer, wherein the rock wool of the rock wool layer is made by melting basalt or other minerals at high temperature, and has excellent fire resistance, heat insulation and sound absorption properties. This embodiment uses a rock wool layer as the fireproof material layer 10 to perform fire separation of the curtain wall system, which can withstand high temperatures of above 800°C.
[0039] Furthermore, the fireproof material layer 10 includes a plurality of rock wool bodies 13, which are designed in a teardrop-shaped structure. Among them, the plurality of rock wool bodies 13 are arranged end to end in an overlapping manner in the fireproof space 8 to maximize the utilization of the fireproof space 8, thereby ensuring that the curtain wall system has an efficient fireproof effect.
[0040] In one embodiment, the fireproof material layer 10 may further include at least one of a flame-retardant foam plastic layer, a cement fiber board layer, a calcium silicate board layer, and a fireproof sealing mud layer.
[0041] Preferably, the fireproof material layer 10 is a calcium silicate board layer.
[0042] Continue to combine Figure 2 and Figure 3 In one embodiment, the thermal insulation material layer 11 includes at least one of a polyurethane foam layer, an extruded polystyrene board layer, an expanded polystyrene board layer, a phenolic foam board layer, and a polyethylene foam layer.
[0043] Preferably, the thermal insulation material layer 11 is a polyurethane foam layer, wherein the polyurethane foam in the polyurethane foam layer has excellent thermal insulation performance and low thermal conductivity (about 0.022 to 0.030 W / m·K), which can effectively block heat transfer and ensure that the curtain wall system has an efficient thermal insulation effect.
[0044] Furthermore, the insulation material layer 11 includes a plurality of polyethylene foam bodies 17, which are designed in a teardrop-shaped structure. The plurality of polyethylene foam bodies 17 are arranged end to end in the insulation space 9 to maximize the utilization of the insulation space 9, thereby ensuring that the curtain wall system has an efficient insulation effect.
[0045] During the specific implementation process, the outer surfaces of the first longitudinal plate 5, the second longitudinal plate 6 and the fire-resistant transverse plate 7 can also be provided with an anti-corrosion coating, wherein the anti-corrosion coating can be an epoxy resin coating, a polyurethane coating or an acrylic coating to improve the service life of the first longitudinal plate 5, the second longitudinal plate 6 and the fire-resistant transverse plate 7, thereby improving the safety of the curtain wall high-efficiency insulation system.
[0046] Continue to combine Figure 4, different from the aforementioned embodiment, the thermal insulation material layer 11 can also include a porous core material 14, an airtight membrane 15 and a negative pressure space 16, wherein the airtight membrane 15 connects the first longitudinal plate 5 and the second longitudinal plate 6, the porous core material 14 is arranged in the airtight membrane 15 and the two ends of the porous core material 14 are in contact with the inner wall of the airtight membrane 15, and the negative pressure space 16 is arranged between the porous core material 14 and the airtight membrane 15. The thermal insulation material layer 11 constructed by this structure, the porous core material 14 supports the airtight membrane 15 and the negative pressure space 16 to prevent the airtight membrane 15 from collapsing due to external atmospheric pressure and provides basic thermal insulation function, the airtight membrane 15 is wrapped around the outside of the porous core material 14 to prevent air or water vapor from entering the negative pressure space 16, thereby reducing the loss of convective heat transfer through the ultra-low heat conductivity of the negative pressure space 16 (close to a vacuum environment), so that the curtain wall system has a high efficiency thermal insulation effect.
[0047] Preferably, the airtight film 15 may be a plastic film or a metal foil film or a combination of a plastic film and a metal foil film.
[0048] In view of the cost of the thermal insulation material layer 11 of this embodiment, the curtain wall high-efficiency thermal insulation system can be applied in important buildings or warehouse environments.
[0049] The above is a detailed introduction to the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the core idea of the present application. At the same time, for those skilled in the art, based on the idea of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
