Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, and in particular to a multi-layer composite laminated tempered glass. Background Technology

[0002] Tempered glass is widely used in many fields such as construction, transportation, and industry due to its high strength, excellent thermal stability, and good safety. Laminated tempered glass, as a common type of tempered glass, is usually made by bonding two or more pieces of tempered glass together with one or more layers of organic polymer interlayer through high-temperature pre-pressing or vacuuming and high-temperature and high-pressure processes. This structure allows the glass to retain the high strength of tempered glass, while preventing fragments from flying and injuring people when it breaks due to impact. This greatly improves safety, so it is widely used in high-rise building safety windows, glass curtain walls, and other scenarios with stringent safety requirements.

[0003] Traditional laminated tempered glass has its functional characteristics basically determined during production. If it is necessary to adjust the function of the glass according to actual needs later, such as adding new functions such as heat insulation and sound insulation to the installed building glass, it is almost impossible to achieve this. This is because its overall laminated structure tightly binds the layers together, making it difficult to replace or improve a specific function individually. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multi-layer composite laminated tempered glass.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-layer composite laminated tempered glass, comprising an inner glass layer and an outer glass layer, wherein outer glass layers are provided on both sides of the inner glass layer, and through holes are provided on the edges of both the inner and outer glass layers, a connecting seat is installed at the through hole of the inner glass layer, and bolt posts are welded on both sides of the connecting seat, one end of the bolt post is through and extends into the through hole of the outer glass layer, and double nuts are screwed onto the surface of the bolt post, the through hole is filled with sealant, and a functional module layer is installed between the outer and inner glass layers.

[0006] By adopting the above technical solution, the functional module layer is set between the outer and inner glass. With the connecting seat, bolt post and double nut structure at the through hole of the inner glass, the functional module layer can be quickly disassembled or replaced. When doing so, only the double nuts need to be unscrewed to separate the outer glass and the inner glass without damaging the overall glass structure. This greatly reduces the difficulty and time cost of replacement, and the glass always maintains its best functional state, which has significant economic and environmental benefits.

[0007] Furthermore, the periphery of the through-holes in the inner and outer glass layers undergoes argon plasma roughening treatment, and a layer of [unspecified material] is deposited around the through-holes. The coating is applied, and the edges of the through holes are chamfered.

[0008] By employing the above technical solution, argon plasma roughening treatment can increase the micro-roughness of the surface around the glass through-holes, expand the contact area, and ensure a firm bond between the subsequent coating and the glass substrate, preventing coating peeling. The coating has high hardness and chemical stability, which can effectively resist external acid and alkali corrosion, water vapor penetration and mechanical friction, extending the service life of glass. The chamfering treatment of the through hole edges can eliminate sharp edges, reduce stress concentration when the glass is under stress, and reduce the probability of cracking.

[0009] Furthermore, an annular sealing gasket is installed between the mating surfaces of the inner and outer glass layers.

[0010] By adopting the above technical solution, the tiny gaps at the glass mating surfaces can be filled, preventing external moisture, dust, and gas from penetrating and ensuring a stable internal environment for the interlayer.

[0011] Furthermore, the functional module layer includes at least one of the following: a sound insulation module, including a damping film layer and a sound-absorbing fiber layer; a bulletproof module, including an aramid fiber cloth layer and a ceramic plate layer; a heat insulation module, including a vacuum layer or an inert gas filling layer; and a dimming module, including a PDLC layer or an EC layer.

[0012] By adopting the above technical solutions, different functional modules can be combined and used according to actual needs to achieve functional integration.

[0013] Furthermore, a plug is installed at the through-hole of the outer glass, and a waterproof rubber ring is installed on the inner side of the plug.

[0014] By adopting the above technical solution, a double sealing structure is formed to prevent rainwater, condensation or dust from entering the through hole.

[0015] Furthermore, the connecting seat is composed of a bolt seat and a threaded seat, wherein the bolt shank at the threaded seat passes through the through hole of the inner glass and is threadedly connected to the threaded hole of the threaded seat.

[0016] By adopting the above technical solution, it is convenient to fix the connector onto the inner glass.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. In this application, by setting the functional module layer between the outer glass and the inner glass, and cooperating with the connecting seat, bolt post and double nut structure at the through hole of the inner glass, the functional module layer can be quickly disassembled or replaced. When doing so, only the double nuts need to be unscrewed to separate the outer glass and the inner layer without damaging the overall glass structure, which greatly reduces the difficulty and time cost of replacement, and the glass always maintains the best functional state, which has significant economic and environmental benefits.

[0019] 2. In this application, argon plasma roughening treatment can increase the micro-roughness of the surface around the glass through-hole, expand the contact area, and make the subsequent coating firmly bonded to the glass substrate, preventing the coating from peeling off. The coating has high hardness and chemical stability, which can effectively resist external acid and alkali corrosion, water vapor penetration and mechanical friction, extending the service life of glass. The chamfering treatment of the through hole edges can eliminate sharp edges, reduce stress concentration when the glass is under stress, and reduce the probability of cracking.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-4As shown in the embodiment of this application, a multi-layer composite laminated tempered glass is disclosed, including an inner glass layer 1 and an outer glass layer 2. The outer glass layer 2 is provided on both sides of the inner glass layer 1, and through holes 3 are provided on the edges of the surfaces of both the inner glass layer 1 and the outer glass layer 2. A connecting seat 4 is installed at the through hole 3 of the inner glass layer 1, and bolt posts 5 are welded on both sides of the connecting seat 4. One end of the bolt post 5 passes through and extends into the through hole 3 of the outer glass layer 2, and a double nut 6 is screwed onto the surface of the bolt post 5. The through hole 3 is filled with sealant, and a functional module layer 7 is installed between the outer glass layer 2 and the inner glass layer 1.

[0027] Outer glass panels are installed on both sides of the inner glass 1, forming a "sandwich"-style basic frame. Through holes 3 are opened through the edges of the inner and outer glass surfaces, forming the core channel for mechanical connection. The corresponding positions of these through holes 3 ensure that the bolts 5 can penetrate the inner and outer glass 2, forming a stable axial fastening force, so that the three-layer structure fits tightly and is not easily misaligned or separated when subjected to external wind pressure, temperature stress and other loads.

[0028] Argon plasma roughening treatment is performed around the through-hole 3 of the inner glass layer 1 and the outer glass layer 2, and argon plasma is deposited around the through-hole 3. Coating 10, the edges of through hole 3 are chamfered.

[0029] Argon plasma roughening treatment was applied to the periphery of the two through-holes in the inner and outer glass layers. High-energy particles bombarded the glass surface, creating a micron-level uneven structure and increasing the surface roughness Ra value to 1.6–3.2 μm. Based on this, deposition was performed... Coating 10 is a dense ceramic coating with a thickness of approximately 1-3 μm, formed using chemical vapor deposition (CVD). This coating not only significantly enhances the wear resistance and corrosion resistance of the inner wall of the through-hole 3, but also forms a dual bond of "mechanical interlocking + chemical bonding" with the roughened glass surface, achieving an adhesion grade of 0 (GB / T 9286 standard). Simultaneously, the chamfering treatment of the edges of the through-hole 3 (typically 45°, with a chamfer width of 0.5-1 mm) eliminates stress concentration points, resulting in a more uniform stress distribution on the glass under load and reducing the risk of cracking around the through-hole 3 due to bolt tightening or temperature changes.

[0030] An annular sealing gasket 9 is installed between the mating surfaces of the inner glass layer 1 and the outer glass layer 2.

[0031] The annular sealing gasket 9 (typically made of EPDM rubber) between the inner and outer glass layers 2 is compressed and deformed during glass assembly, filling the microscopic gaps on the glass surface to form a continuous sealing ring. Its compression rate is designed to be 15%-20%, ensuring it maintains an elastic seal during long-term use. The annular sealing gasket 9 not only blocks the intrusion of external moisture and dust but also buffers displacement caused by thermal expansion and contraction of the glass (compensation can reach ±0.5mm), preventing stress concentration and damage caused by direct glass contact.

[0032] The functional module layer 7 includes at least one of the following: a sound insulation module, including a damping film layer and a sound-absorbing fiber layer; a bulletproof module, including an aramid fiber cloth layer and a ceramic plate layer; a heat insulation module, including a vacuum layer or an inert gas filling layer; and a dimming module, including a PDLC layer or an EC layer.

[0033] Functional module layer 7 serves as the core functional carrier, encompassing various modules such as sound insulation, bulletproofing, heat insulation, and dimming. Each module employs standardized dimensional design, forming a precise fit with the inner and outer glass layers 2. For example, the damping film layer and sound-absorbing fiber layer in the sound insulation module are integrated into a single structure through a hot-pressing composite process, with a thickness controlled between 1 and 3 mm. During installation, it is directly embedded between the inner and outer glass layers 2 and fixed to the glass edges with sealant, achieving sound wave attenuation. Different functional modules can be combined according to actual needs to achieve functional synergy. For instance, when the heat insulation module (vacuum layer or inert gas filling layer) is combined with the sound insulation module, the vacuum layer or inert gas not only reduces heat conduction but also assists in sound insulation by reducing the transmission of sound wave energy through gas molecule vibration, thereby improving the overall sound insulation effect by 5-8 dB. The ceramic plate layer and aramid fiber cloth layer of the bulletproof module are bonded together with structural adhesive to form a "hard-soft" composite protection system: the ceramic plate first shatters the bullet, and the aramid fiber cloth absorbs the remaining kinetic energy, achieving high-efficiency bulletproof performance while maintaining the light transmission integrity of the glass.

[0034] A plug 8 is installed at the through hole 3 of the outer glass 2, and a waterproof rubber ring is installed on the inner side of the plug 8.

[0035] The sealant (such as silicone sealant) filling the through hole 3 fills the remaining gap after the bolt post 5 is installed, forming a waterproof and dustproof sealing barrier. The elasticity of the sealant can buffer the mechanical friction between the bolt post 5 and the glass hole wall, avoiding glass damage caused by rigid contact, while preventing external moisture from seeping into the interlayer, ensuring a stable operating environment for the functional module layer 7.

[0036] The connecting seat 4 consists of a bolt seat and a threaded seat. The bolt shank at the threaded seat passes through the through hole 3 of the inner glass 1 and is threadedly connected to the threaded hole of the threaded seat.

[0037] The connector 4 adopts a split structure design. The screw hole of its threaded seat is precisely coaxial with the through hole 3 of the inner glass 1. The bolt seat passes through the through hole 3 of the inner glass 1 and is connected to the threaded seat by threaded engagement. This design makes it easy to fix the connector 4 on the inner glass 1.

[0038] The operating principle of the multi-layer composite laminated tempered glass in this embodiment is as follows: The multi-layer composite laminated tempered glass adopts a sandwich structure of "inner glass 1 - functional module layer 7 - outer glass 2", and is fastened by the connecting seat 4, bolt post 5, and double nuts 6 at the through holes 3 at the edges of the inner and outer glass layers 2. When the glass is subjected to external loads (such as wind pressure or impact), the axial preload provided by the bolt post 5 makes the three-layer structure fit tightly together, forming an overall stress-bearing system. The inner and outer glass layers 2, as the main load-bearing components, disperse the external force to the entire glass surface; the functional module layer 7 plays a buffering and coordinating role in the middle, avoiding stress concentration on a certain glass layer, and greatly improving the glass's wind pressure resistance and impact resistance.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
