Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, specifically to a composite SGP laminated glass. Background Technology

[0002] SGP glass is a type of safety glass that uses an SGP ionomer interlayer as a laminate. Its structural design aims to provide high strength, impact resistance, and excellent mechanical properties. Its typical structure usually consists of an outer glass layer, an intermediate SGP film, and an inner glass layer. It is mostly used as safety glass in buildings, such as large curtain walls and skylights.

[0003] Due to limitations in production and subsequent installation and transportation, glass installation in most applications requires splicing. Traditional structures use metal frames or exposed joints with adhesive, but this results in noticeable seams that affect aesthetics and insufficient strength at the joints. In the market, as shown in the technical solution with authorization announcement number CN 219883437 U, a spliced ​​SGP laminated glass includes multiple laminated glass bodies, with a metal strip slidingly engaging between two of the laminated glass bodies. Each laminated glass body includes an SGP film; glass substrates are fixed to both ends of the SGP film; rails are fixed to opposite sides of the two glass substrates; and slots are provided on opposite sides of the two glass substrates. The rail fixed to one side of one glass substrate engages with the slot on the other side of the glass substrate.

[0004] However, under this structure, the glass as a whole is still a traditional tightly stacked structure, spliced ​​by side rails and slots. When under stress, the structural support for the edge of the glass substrate is insufficient, and part of the edge of the SGP film is exposed. During installation, it is easily contaminated and affects the overall aesthetics. Utility Model Content

[0005] Therefore, this utility model provides a composite SGP laminated glass, which solves the problem of insufficient strength during the installation of current SPG laminated glass.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A composite SGP laminated glass includes multiple glass modules. Each glass module includes an outer glass layer, an SGP interlayer, a middle glass layer, and an inner glass layer stacked sequentially. Edge supports are provided around the middle glass layer and the inner glass layer to form a hollow layer between the middle glass layer and the inner glass layer. The edge supports have a support end extending into the hollow layer, an extension end extending to the edge of the outer glass layer, and a wrapping end extending to the peripheral edge of the inner glass layer. The edge supports on the side opposite to the support end are provided with a protrusion and a slot for splicing the glass modules.

[0008] Preferably, the upper edge of the outer glass layer is pre-cut with a chamfer, and the top of the extension end extends to the chamfer. When adjacent glass modules are joined, an adhesive layer is filled between the extension end and the chamfer on the two adjacent glass modules, and a sealant layer is provided on the outer surface of the adhesive layer to fill the gap between the two glass modules.

[0009] Preferably, the peripheral edge of the outer glass extends out of the middle glass to form a protruding section, the lower edge of the protruding section is pre-cut with a chamfer, and the end of the extension abuts against the chamfer. When adjacent glass modules are joined, the gap between the two adjacent glass modules is filled with a sealant layer.

[0010] Preferably, the edge support is made of TPE material and is bonded to the outer glass, middle glass and inner glass by a high-strength structural adhesive.

[0011] Preferably, the thickness of the outer glass layer is 1.5-3 times the thickness of the middle and inner glass layers.

[0012] Preferably, the hollow layer is provided with warm edge spacers on its periphery.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] This technical solution adds edge supports to the traditional SGP glass, connecting the glass modules for installation. This separates the installation structure from the hollow layer outside the outer glass, increasing the structural support thickness on the outer surface of the installation structure. During installation, mortise and tenon joints are used via protrusions and slots on the edge supports, allowing for sufficiently small edge gaps between the outer glass modules. Unlike traditional exposed frame splicing, this solution achieves a "seamless" visual effect for the outer glass while ensuring structural strength. The hollow layer structure also reduces thermal bridging and provides insulation and soundproofing, combining aesthetics and practicality. It is particularly suitable for use in large-span buildings such as ultra-high-rise curtain walls and airport terminals. Attached Figure Description

Detailed Implementation

[0019] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example 1

[0020] refer to Figure 1 and Figure 2 A composite SGP laminated glass, in which multiple glass modules 100 are spliced ​​together, is used. Here, the combination of two glass modules 100 is taken as an example:

[0021] Each of the glass modules 100 includes an outer glass layer 1, an SGP interlayer 2, a middle glass layer 3, and an inner glass layer 4 stacked sequentially. An edge support 6 is provided around the middle glass layer 3 and the inner glass layer 4 to form a hollow layer between the middle glass layer 3 and the inner glass layer 4. The hollow layer is filled with an inert gas (argon, etc.). In terms of material, the edge support 6 is made of TPE material with a thermal conductivity ≤0.18 W / (m•K) and is bonded to the outer glass layer 1, the middle glass layer 3, and the inner glass layer 4 by a high-strength structural adhesive 66. Structurally, the edge support 6 has a support end 61 extending into the hollow layer, an extension end 62 extending to the edge of the outer glass layer 1, and a wrapping end 63 extending to the peripheral edge of the inner glass layer 4. A warm edge spacer 5 is provided around the periphery of the hollow layer, and the support end 61 extends into and abuts against the warm edge spacer 5 to form a traditional hollow sealed glass structure.

[0022] The edge bracket 6, located on the opposite side of the support end 61, is provided with protrusions 64 and slots 65 for splicing glass modules 100. The protrusions 64 and slots 65 on the two glass modules 100 cooperate with each other to splice, forming a mortise and tenon joint structure, which is convenient for installation. This technical solution, by adding edge brackets 6, installs glass modules 100 between them through the connection of edge brackets 6 on the basis of traditional SGP glass. The installation structure is independent of the hollow layer outside the outer glass 1, which increases the structural support thickness of the outer surface of the installation structure. During installation, the protrusions 64 and slots 65 on the edge brackets 6 are used for mortise and tenon installation. The edge gaps of the outer glass 1 between each glass module 100 can be made small enough. Unlike the traditional exposed frame splicing, it achieves a "seamless" visual effect of the outer glass 1 while ensuring structural strength. The hollow layer structure can also reduce the thermal bridge effect and provide certain heat insulation and sound insulation functions. It has both aesthetics and practicality, and is particularly suitable for use in large-span buildings such as super high-rise curtain walls and airport terminals.

[0023] In the design, to ensure the weight of a single glass module 100, glass of different thicknesses and materials can be used as the substrate. In this embodiment, the thickness of the outer glass 1 is 1.5-3 times that of the middle glass 3 and the inner glass 4. This glass module 100 has an asymmetrical thickness design, which ensures the strength of the outer glass 1 while reducing the thickness of the middle glass 3 and the inner glass 4 to obtain a more reasonable weight, reduce material costs, and facilitate subsequent transportation and installation.

[0024] In this embodiment, the outer glass 1 is designed with a pre-cut chamfered portion 11 at its upper edge. The chamfered portion 11 has a 45° bevel angle, and the top of the extension end 62 extends to the bottom edge of the chamfered portion 11. When adjacent glass modules 100 are joined, an adhesive layer 7 is filled between the extension end 62 and the chamfered portion 11 on the two adjacent glass modules 100. A sealant layer 8 is provided on the outer surface of the adhesive layer 7 to fill the gap between the two glass modules 100. The adhesive layer 7 is made of UV-cured acrylic adhesive, which ensures the connection between the two glass modules 100 and the extension end 62 of the edge support 6 in the middle. The outer layer can be filled with a suitable sealant according to the design requirements to achieve the desired visual effect and ensure the flatness and aesthetics of the entire glass surface. A sealant of the same color as the glass can be selected to further minimize the appearance of gaps. Example 2

[0025] refer to Figure 3Compared to Embodiment 1, the peripheral edge of the outer glass 1 extends beyond the middle glass 3 to form a protruding section 1a. The lower edge of the protruding section 1a is pre-cut with a chamfered portion 11, which can be 30-45°. The end of the extension end 62 abuts against the chamfered portion 11, and the abutting end of the extension end 62 is cut to form a corresponding bevel to fit the chamfered portion 11. When adjacent glass modules 100 are joined, the gap between the two adjacent glass modules 100 is filled with a sealant layer 8. Compared to Embodiment 1, the gap width is further reduced. The sealant layer 8 here can be selected from silicone or polyurethane elastomer to form a flexible transition structure that can absorb the stress generated by thermal expansion and contraction or impact. This embodiment is suitable for scenarios that do not require load-bearing capacity or have low airtightness requirements, in order to meet the needs of rapid construction and easy disassembly and assembly later.
