Description

Technical Field

[0001] This disclosure relates to the technical field of glass curtain walls, and in particular to a bird-identifiable glass interlayer film for buildings and a glass curtain wall. Background Technology

[0002] Glass has been immensely popular since its invention, widely used in various buildings due to its transparency and aesthetic appeal. However, this transparency also presents a challenge for birds. Unlike humans, birds have stronger lateral vision than frontal vision. In flight, birds often need to turn their heads or backs to warn of predators and search for prey, making it difficult for them to effectively spot obstacles ahead. Birds cannot perceive transparent glass as an impassable barrier and can easily mistake it for an extension of the sky or natural environment, causing them to accelerate straight into glass curtain walls, resulting in frequent bird strikes. The key to preventing bird strikes is to make birds "see" the glass.

[0003] To make birds "see" the presence of glass, patent CN 115215558 A proposes a bird-proof glass, which includes a glass substrate and a bird-proof coating attached to the non-outer surface of the glass substrate. The bird-proof coating covers 10% to 70% of the surface on the glass substrate to form a film pattern. Although it can prevent bird strikes, the user's visual integrity of the glass is compromised, i.e., the pattern is obscured. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a bird-identifiable architectural glass interlayer film and glass curtain wall that can reduce the user's visual impact on the glass's visual integrity and achieve bird warning without the need for setting up a film pattern structure.

[0005] The purpose of this disclosure is achieved through the following technical solution: A bird-identifying interlayer glass film for architectural use, used to clamp between two sets of glass components, each set of glass components including glass and a light-transmitting protective film attached to the inner side of the glass. The bird-identifying interlayer glass film includes sequentially stacked bird warning fluorescent coatings and light-transmitting coated substrate films. The bird-identifying interlayer glass film is adhered between the light-transmitting protective films of the two sets of glass components, with the side of the bird warning fluorescent coating facing away from the light-transmitting coated substrate film adhered to the light-transmitting protective film of the outer side of the glass component. The thickness of the bird warning fluorescent coating is less than or equal to 100 μm; The thickness of the light-transmitting protective film for each set of glass components is less than or equal to 3 mm.

[0006] In one embodiment, the light-transmitting protective film is at least one of a PVB film, a POE film, an EVA film, or an SGP film.

[0007] In one embodiment, the light-transmitting coated substrate film is at least one of a PVB film, a PET film, an EVA film, or an SGP film.

[0008] In one embodiment, the light transmittance of the light-transmitting coated substrate film is greater than or equal to 70%.

[0009] In one embodiment, the thickness of the light-transmitting coated substrate film is 100 micrometers to 500 micrometers.

[0010] In one embodiment, the thickness of the glass in each group of glass pieces is greater than or equal to 15 mm.

[0011] In one embodiment, the bird warning fluorescent coating is a screen coating or a spray coating.

[0012] A glass curtain wall, comprising the bird-identifiable architectural glass interlayer film as described in any of the above embodiments, the glass curtain wall further comprising two sets of glass components and curtain wall structural components, the two sets of glass components comprising a first glass component and a second glass component; the first glass component comprising a first glass and a first light-transmitting protective film, the second glass component comprising a second glass and a second light-transmitting protective film. The first glass component, the first light-transmitting protective film, the bird-identifiable architectural glass interlayer film, the second light-transmitting protective film, and the second glass component are sequentially stacked to form a glass installation structure, and the curtain wall structural component is connected to the glass installation structure.

[0013] In one embodiment, the curtain wall structure is a frame, and the glass mounting structure is embedded in and glued to the frame.

[0014] In one embodiment, the curtain wall structural member includes a connected metal connector and a supporting structure, and the glass mounting structure has a fixing hole, in which the metal connector is fixed.

[0015] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned bird-identifying architectural glass interlayer film is sandwiched between two sets of glass components. During assembly, the bird warning fluorescent coating can first be adhered to the light-transmitting coating substrate film or the light-transmitting protective film of the outer glass component. Then, the bird-identifying architectural glass interlayer film is sandwiched and adhered between the light-transmitting protective films of the two sets of glass components. The side of the bird warning fluorescent coating that faces away from the light-transmitting coating substrate film is adhered to the light-transmitting protective film of the outer glass component. Since the bird-identifying architectural glass interlayer film includes sequentially stacked bird warning fluorescent coating and light-transmitting coating substrate film, on the one hand, it ensures that sufficient ultraviolet light passes through the light-transmitting protective film of the outer glass component to enter the bird warning fluorescent coating to cause reflected or refracted light so that birds can identify it. On the other hand, it prevents the problem of ultraviolet aging of the light-transmitting coating substrate film caused by excessive ultraviolet light irradiation.

[0016] The aforementioned bird-identifying interlayer glass film for buildings has high light transmittance, which can reduce the impact on the visual integrity of the glass for users; moreover, the bird warning fluorescent coating is directly bonded to the light-transmitting coating substrate film, and the bird-identifying interlayer glass film for buildings can achieve the bird warning function without setting up a film pattern structure, making the processing of glass curtain walls simpler and more convenient.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figure 1 and Figure 2 As shown, a bird-identifying interlayer glass film 10 of this utility model is used to clamp two sets of glass components 20. Each set of glass components 20 includes glass 22 and a light-transmitting protective film 24 attached to the inner side of the glass 22. The bird-identifying interlayer glass film 10 includes sequentially stacked bird warning fluorescent coating 12 and light-transmitting coated substrate film 14. The bird-identifying interlayer glass film 10 is attached between the light-transmitting protective films 24 of the two sets of glass components 20. The side of the bird warning fluorescent coating 12 facing away from the light-transmitting coated substrate film 14 is attached to the light-transmitting protective film 24 of one side of the glass component 20. The thickness of the bird warning fluorescent coating is less than or equal to 100 μm; the thickness of the light-transmitting protective film 24 of each set of glass components 20 is less than or equal to 3 mm.

[0023] See also Figure 3The aforementioned bird-identifying architectural glass interlayer film 10 is sandwiched between two sets of glass components 20. During assembly, the bird warning fluorescent coating can first be adhered to the light-transmitting coating substrate film or the light-transmitting protective film of the outer glass component. Then, the bird-identifying architectural glass interlayer film is sandwiched and adhered between the light-transmitting protective films of the two sets of glass components. The side of the bird warning fluorescent coating that is away from the light-transmitting coating substrate film is adhered to the light-transmitting protective film of the outer glass component. Since the bird-identifying architectural glass interlayer film 10 includes at least one stacked bird warning fluorescent coating 12 and light-transmitting coating substrate film 14, on the one hand, it ensures that enough ultraviolet light passes through the light-transmitting protective film 24 of the outer glass component to enter the bird warning fluorescent coating 12 to cause reflected or refracted light so that birds can identify it. On the other hand, it prevents the problem of ultraviolet aging of the light-transmitting coating substrate film 14 caused by excessive ultraviolet light irradiation. The aforementioned bird-identifying architectural glass interlayer film 10 has a high light transmittance, which can reduce the impact on the visual integrity of the glass 22 for users; moreover, the bird warning fluorescent coating 12 is bonded to the light-transmitting coating substrate film 14, and the bird-identifying architectural glass interlayer film 10 can achieve the bird warning function without setting up a film pattern structure, making the processing of glass curtain walls simpler and more convenient.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, there is one bird warning fluorescent coating 12. The bird warning fluorescent coating 12 and the light-transmitting coating substrate film 14 are stacked sequentially. The bird-identifiable architectural glass interlayer film 10 is attached between the light-transmitting protective films 24 of the two sets of glass components 20. The side of the bird warning fluorescent coating 12 that is away from the light-transmitting coating substrate film 14 is attached to the light-transmitting protective film 24 of the outer glass component 20.

[0025] It is understood that in other embodiments, when both sides of the bird-identifiable architectural glass interlayer film 10 are intended to warn birds, such as in non-enclosed glass wall buildings, the bird-identifiable architectural glass interlayer film 10 is not limited to requiring a bird warning fluorescent coating 12, such as... Figure 4 and Figure 5As shown, for example, the bird-identifying architectural glass interlayer film 10 includes a light-transmitting coated substrate film 14 and two bird warning fluorescent coatings 12, namely a first bird warning fluorescent coating 122 and a second bird warning fluorescent coating 124; the first bird warning fluorescent coating 122, the light-transmitting coated substrate film 14, and the second bird warning fluorescent coating 124 are sequentially laminated. The first bird warning fluorescent coating 122 and the second bird warning fluorescent coating 124 are respectively bonded to the light-transmitting protective film 24 of the corresponding glass component 20. On the one hand, this ensures that sufficient ultraviolet light passes through the corresponding light-transmitting protective film 24 to enter the first bird warning fluorescent coating 122 or the second bird warning fluorescent coating 124 to cause reflected or refracted light, so that birds can identify the object. In this way, the bird-identifying architectural glass interlayer film 10 serves as a bird warning on both sides of the two sets of glass components, and there is no need to distinguish between the inside and outside during installation, which is convenient for use. On the other hand, it prevents the problem of ultraviolet aging of the light-transmitting coated substrate film 14 caused by excessive ultraviolet light exposure.

[0026] It is understandable that the bird warning fluorescent coating 12 can use fluorescent materials with existing technology, such as CN106128330B, CN112248580A and CN111548659A. The fluorescent materials achieve the effect of "birds can see but people cannot" under ultraviolet light emission or irradiation, thereby playing a warning role for birds.

[0027] like Figure 1 As shown, in one embodiment, the light-transmitting protective film 24 is at least one of a PVB film, a PET film, an EVA film, or an SGP film, giving the light-transmitting protective film 24 good safety, sound insulation, flexibility, impact resistance, and weather resistance, while reliably bonding and fixing the interlayer film of the glass 22 to the inner side of the glass 22 through the light-transmitting protective film 24. In this embodiment, the light-transmitting protective film 24 is a PVB film. It can be understood that in other embodiments, the light-transmitting protective film 24 can also be a PET film, an EVA film, or an SGP film, or it can also be a film composed of any two of the following: a PVB film, a PET film, an EVA film, or an SGP film. For example, the light-transmitting protective film 24 is a combination of a PVB film and a PET film.

[0028] like Figure 1 and Figure 2As shown, in one embodiment, the light-transmitting coated substrate film 14 is at least one of a PVB film, a PET film, an EVA film, or an SGP film, giving the light-transmitting coated substrate film 14 high transparency and strength, while also giving it low heat shrinkage. This ensures that the pattern on the light-transmitting coated substrate film 14 does not change due to substrate deformation under harsh environments. Furthermore, the light-transmitting coated substrate film 14 has high flatness, easily achieving the integrity of the pattern shapes of the emitting / reflecting first and second warning fluorescent coatings, allowing the interlayer film of the glass 22 to be reliably clamped within the two sets of glass components 20. In this embodiment, the light-transmitting coated substrate film 14 is a PET film, allowing both the first bird warning fluorescent coating 12 and the second bird warning fluorescent coating 16 to be well bonded to the light-transmitting coated substrate film 14. In other embodiments, the light-transmitting coated substrate film 14 may also be a PVB film, an EVA film, or an SGP film, or a film that is a combination of any two of the following: a PVB film, a PET film, an EVA film, or an SGP film. For example, the light-transmitting coated substrate film 14 may be a combination of a PVB film and a PET film.

[0029] like Figure 2 As shown, in one embodiment, the light transmittance of the light-transmitting coated substrate film 14 is greater than or equal to 70%, which enables birds to recognize the architectural glass interlayer film 10 with good light transmittance, achieving the effect of "birds can see it but people cannot".

[0030] like Figure 2 As shown, in one embodiment, the thickness of the light-transmitting coated substrate film 14 is 100 micrometers to 500 micrometers.

[0031] like Figure 1 As shown, in one embodiment, the thickness of the glass 22 of each set of glass elements 20 is greater than or equal to 15 mm.

[0032] In one embodiment, the bird warning fluorescent coating 12 is a screen-coated or spray-coated coating. In this embodiment, the bird warning fluorescent coating 12 can be formed on the light-transmitting coating substrate film 14 by screen-coating or spray-coating, making it easy to form and manufacture the bird-identifiable architectural glass interlayer film 10.

[0033] like Figure 1 or Figure 4 As shown, this application also provides a glass curtain wall 30, which includes the bird-identifiable architectural glass interlayer film 10 described in any of the above embodiments, and see also... Figure 6The glass curtain wall also includes two sets of glass components 20 and curtain wall structural components 30. The two sets of glass components 20 include a first glass component 20a and a second glass component 20b. The first glass component 20a includes a first glass and a first light-transmitting protective film, and the second glass component 20b includes a second glass and a second light-transmitting protective film. The first glass component 20a, the first light-transmitting protective film, the bird-identifiable architectural glass interlayer film, the second light-transmitting protective film, and the second glass component 20b are sequentially stacked to form a glass installation structure. The curtain wall structural components are connected to the glass installation structure.

[0034] The aforementioned glass curtain wall utilizes the aforementioned bird-identifying architectural glass interlayer film 10. During assembly, the bird warning fluorescent coating can first be adhered to the light-transmitting coating substrate film or the light-transmitting protective film of the outer glass component. Then, the bird-identifying architectural glass interlayer film is clamped and adhered between the light-transmitting protective films of the two sets of glass components. The side of the bird warning fluorescent coating that faces away from the light-transmitting coating substrate film is adhered to the light-transmitting protective film of the outer glass component. Since the bird-identifying architectural glass interlayer film 10 includes at least one stacked bird warning fluorescent coating 12 and light-transmitting coating substrate film 14, on the one hand, sufficient ultraviolet light is ensured to pass through the light-transmitting protective film 24 of the outer glass component and enter the bird warning fluorescent coating 12 to cause reflected or refracted light so that birds can identify it. On the other hand, excessive ultraviolet light irradiation is prevented from causing ultraviolet aging of the light-transmitting coating substrate film 14. The aforementioned bird-identifying architectural glass interlayer film 10 has a high light transmittance, which can reduce the impact on the visual integrity of the glass 22 for users; moreover, the bird warning fluorescent coating 12 is directly bonded to the light-transmitting coating substrate film 14, and the bird-identifying architectural glass interlayer film 10 can achieve the bird warning function without setting up a film pattern structure, making the processing of glass curtain walls simpler and more convenient.

[0035] It should be noted that if the number of bird warning fluorescent coatings 12 is one, such as Figure 1 and Figure 2 As shown, during assembly, the bird warning fluorescent coating 12 and the light-transmitting coating substrate film 14 are sequentially stacked, and the bird-identifiable architectural glass interlayer film 10 is attached between the light-transmitting protective films 24 of the two sets of glass components 20. The side of the bird warning fluorescent coating 12 facing away from the light-transmitting coating substrate film 14 is attached to the light-transmitting protective film 24 of the outer glass component 20. This bird-identifiable architectural glass interlayer film 10 is used for a single-sided bird warning scenario in glass curtain walls.

[0036] If the number of bird warning fluorescent coatings 12 is two, such as Figure 3 and Figure 4As shown, the two bird warning fluorescent coatings 12 are a first bird warning fluorescent coating 122 and a second bird warning fluorescent coating 124, respectively. During assembly, the first bird warning fluorescent coating 122, the light-transmitting coated substrate film 14, and the second bird warning fluorescent coating 124 are sequentially layered and bonded together. The first bird warning fluorescent coating 122 and the second bird warning fluorescent coating 124 are respectively bonded to the light-transmitting protective film 24 of the corresponding glass component 20. This allows for bird recognition in the scenario where the architectural glass interlayer film 10 is used to warn birds on both sides of the glass curtain wall, making installation more flexible and convenient.

[0037] like Figure 6 As shown, in one embodiment, the curtain wall structure 30 is a frame, and the glass mounting structure is embedded in and glued to the frame 30, so that the glass mounting structure is fixed to the curtain wall structure.

[0038] In other embodiments, the curtain wall structural member 30 is not limited to a frame. For example, in one embodiment, the curtain wall structural member includes a connected metal connector (not shown) and a supporting structure (not shown). The glass mounting structure has fixing holes, and the metal connector is fixed in the fixing holes, so that the glass mounting structure is fixedly connected to the supporting structure through the metal connector, thereby realizing the assembly of the glass mounting structure. In this embodiment, the metal connector is a stainless steel connector claw.

[0039] Compared with the prior art, this disclosure has at least the following advantages: 1) The bird-identifying architectural glass interlayer film 10 described above is sandwiched between two sets of glass components 20. Since the bird-identifying architectural glass interlayer film 10 includes a first bird warning fluorescent coating 12, a light-transmitting coated substrate film 14 and a second bird warning fluorescent coating 16 stacked in sequence, the first bird warning fluorescent coating 12 and the second bird warning fluorescent coating 16 are respectively attached to the light-transmitting protective film 24 of the corresponding glass component 20. On the one hand, it ensures that enough ultraviolet light passes through the corresponding light-transmitting protective film 24 to enter the first bird warning fluorescent coating 12 or the second bird warning fluorescent coating 16 to cause reflected or refracted light so that birds can identify it. On the other hand, it prevents the problem of ultraviolet aging of the light-transmitting coated substrate film 14 caused by excessive ultraviolet light irradiation.

[0040] 2) The bird-identifying architectural glass interlayer film 10 mentioned above has a high light transmittance, which can reduce the impact on the visual integrity of the glass 22 for users; moreover, the first bird warning fluorescent coating 12 and the second bird warning fluorescent coating 16 are directly coated on the light-transmitting coating substrate film 14, without the need to set up a film pattern structure, so that the bird-identifying architectural glass interlayer film 10 can achieve the bird warning function, making the processing of glass curtain walls simpler and more convenient.

[0041] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
