Description

Technical Field

[0001] This utility model is a type of laminated glass that can be spliced ​​together, belonging to the field of glass splicing technology. Background Technology

[0002] Laminated glass is widely used in building curtain walls, interior partitions, and doors and windows due to its advantages such as high strength, high safety, and good sound insulation. However, in some large-scale applications, the size of a single piece of laminated glass is limited by production processes and transportation conditions, so it is necessary to splice them together to achieve large-area coverage.

[0003] However, the traditional laminated glass splicing method is relatively simple, which may lead to uneven stress distribution at the splicing point, increasing the risk of glass breakage. The sealing material at the splicing point is prone to aging or damage, causing moisture to seep in and affecting the service life and appearance of the glass. There is an urgent need for a spliced ​​laminated glass to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a spliced ​​laminated glass to solve the problems mentioned in the background. This invention uses a flexible transition layer to effectively absorb and disperse stress at the splicing point, reducing stress concentration and improving the safety and durability of the splicing point. At the same time, it uses a snap-fit ​​method to firmly fix the two pieces of laminated glass together, ensuring the strength and stability of the splicing point. Finally, a double-seal protection design is used to prevent moisture infiltration.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a spliced ​​laminated glass, comprising a first laminated glass body, a second laminated glass body, an aluminum alloy connecting groove seat, and an aluminum alloy protrusion. The first laminated glass body is located directly to the left of the second laminated glass body. A first flexible transition layer is bonded to the right side of the first laminated glass body via waterproof adhesive. A second flexible transition layer is bonded to the left side of the second laminated glass body via waterproof adhesive. A waterproof sealing strip is bonded to the inner wall of the aluminum alloy connecting groove seat. Multiple wedge-shaped grooves are symmetrically formed at the upper and lower ends of the aluminum alloy connecting groove seat. Weather-resistant sealing strips are bonded to the upper and lower ends of the left side of the aluminum alloy protrusion. The aluminum alloy protrusion is inserted into the aluminum alloy connecting groove seat. Multiple embedding grooves are formed at the upper and lower ends of the aluminum alloy protrusion. A groove seat is installed in each of the multiple embedding grooves. An elastic sponge block is bonded to the middle of each of the multiple groove seats. Wave springs are longitudinally welded to the front and rear ends of each of the multiple groove seats. Wedge-shaped locking blocks are installed at the movable ends of each of the multiple wave springs.

[0006] Furthermore, both the first flexible transition layer and the second flexible transition layer are made of silicone rubber or elastic resin.

[0007] Furthermore, six hexagonal bolts are inserted between the aluminum alloy connecting groove, the waterproof sealing strip, the first flexible transition layer and the first laminated glass body, and six hexagonal bolts are inserted between the aluminum alloy protrusion, the second flexible transition layer and the second laminated glass body.

[0008] Furthermore, the left end of the aluminum alloy protrusion is tightly abutted against the waterproof sealing strip, and the left ends of both weather-resistant sealing strips are tightly abutted against the aluminum alloy connecting groove seat.

[0009] Furthermore, all of the wave springs are in a semi-compressed state, and all of the wave springs are made of stainless steel.

[0010] Furthermore, multiple wedge-shaped blocks are inserted into multiple wedge-shaped grooves, and the multiple wedge-shaped blocks are made of spring steel with their surfaces nitrided.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a spliced ​​laminated glass system. By adding a first flexible transition layer, a second flexible transition layer, an aluminum alloy connecting groove, a waterproof sealing strip, an aluminum alloy protrusion, a weather-resistant sealing strip, a wedge-shaped clip, a groove seat, an elastic sponge block, and a wave spring, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The flexible transition layer effectively absorbs and disperses stress at the splicing point, reducing stress concentration and improving the safety and durability of the splicing point. Simultaneously, the two pieces of laminated glass are firmly fixed together by a snap-fit ​​mechanism, ensuring the strength and stability of the splicing point. Finally, a double-seal protection design is provided: the first weather-resistant sealing strip resists the influence of the external environment, while the second waterproof sealing strip further enhances the sealing effect and prevents moisture penetration.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a spliced ​​laminated glass, including a first laminated glass body 1, a second laminated glass body 2, an aluminum alloy connecting groove seat 5, and an aluminum alloy protrusion 9. The first laminated glass body 1 is located directly to the left of the second laminated glass body 2. A first flexible transition layer 3 is bonded to the right side of the first laminated glass body 1 with waterproof adhesive. A second flexible transition layer 4 is bonded to the left side of the second laminated glass body 2 with waterproof adhesive. A waterproof sealing strip 7 is bonded to the inner wall of the aluminum alloy connecting groove seat 5. Multiple wedge-shaped grooves 8 are symmetrically formed at the upper and lower ends inside the aluminum alloy connecting groove seat 5. Weather-resistant materials are bonded to the upper and lower ends of the left side of the aluminum alloy protrusion 9. The sealing strip 10 and the aluminum alloy protrusion 9 are inserted into the aluminum alloy connecting groove seat 5. The upper and lower ends of the aluminum alloy protrusion 9 are provided with multiple embedded grooves 11. Each embedded groove 11 is equipped with a groove seat 13. Each groove seat 13 has an elastic sponge block 14 glued to its middle. Wave springs 15 are longitudinally welded to the front and rear ends of each groove seat 13. Each wave spring 15 has a wedge-shaped locking block 12 installed on its movable end. This design solves the problems of the traditional laminated glass splicing method being relatively simple, which may lead to uneven stress distribution at the splicing point, increasing the risk of glass breakage, and the sealing material at the splicing point being prone to aging or damage, resulting in water vapor infiltration.

[0020] As the first embodiment of this utility model: both the first flexible transition layer 3 and the second flexible transition layer 4 are silicone rubber or elastic resin. By adding both the first flexible transition layer 3 and the second flexible transition layer 4, which are both silicone rubber or elastic resin, this layer can not only absorb and disperse the stress at the splice and reduce the stress concentration phenomenon, but also provide a certain buffering effect, thereby improving the safety and durability of the overall structure.

[0021] Six hexagonal socket head caps 6 are inserted between the aluminum alloy connecting groove seat 5, the waterproof sealing strip 7, the first flexible transition layer 3 and the first laminated glass body 1. Six hexagonal socket head caps 6 are also inserted between the aluminum alloy protrusion 9, the second flexible transition layer 4 and the second laminated glass body 2. The six hexagonal socket head caps 6 can be used to fix the aluminum alloy connecting groove seat 5, the waterproof sealing strip 7, the first flexible transition layer 3 and the first laminated glass body 1. The other six hexagonal socket head caps 6 can be used to fix the aluminum alloy protrusion 9, the second flexible transition layer 4 and the second laminated glass body 2.

[0022] The left end of the aluminum alloy protrusion 9 is tightly abutted against the waterproof sealing strip 7, and the left ends of the two weather-resistant sealing strips 10 are tightly attached to the aluminum alloy connecting groove seat 5. The two added weather-resistant sealing strips 10 can fill the gap on the outside of the aluminum alloy protrusion 9 and the aluminum alloy connecting groove seat 5 to prevent moisture and air penetration. The waterproof sealing strip 7 can fill the gap on the inside of the aluminum alloy protrusion 9 and the aluminum alloy connecting groove seat 5, further enhancing the sealing effect on the basis of the first layer of sealing.

[0023] Multiple wave springs 15 are all in a semi-compressed state. All wave springs 15 are made of stainless steel. Due to their high stability and small installation space, wave springs 15 are widely used in precision equipment (such as automotive fuel injection systems), and their fatigue life is >10. 6 The performance of this spring (GB / T 1239.2-2009) is significantly higher than that of ordinary helical springs. Random vibration tests were conducted according to GB / T 2423.10-2019 (frequency 10-500Hz, acceleration 5g, duration 2h), and the results showed: displacement at the snap-fit ​​point < 0.1mm; spring preload attenuation rate < 3%.

[0024] Multiple wedge-shaped blocks 12 are inserted into multiple wedge-shaped grooves 8. The multiple wedge-shaped blocks 12 are all made of spring steel and their surfaces are nitrided. The wedge-shaped blocks 12 have a wedge angle of 15° and form a surface contact with the inclined surfaces of the multiple wedge grooves 8, which increases the friction and shear resistance. Combined with the nitriding treatment, the wear resistance is increased by 3 times, avoiding deformation and failure after long-term use. According to the "Connection and Fastening" section of Volume 2 of the "Mechanical Design Handbook" (Sixth Edition), wedge-shaped inclined surface locking can achieve boltless fixing through the self-locking effect (friction angle > inclined surface angle).

[0025] As a second embodiment of this utility model: In actual splicing and use, an outer thin plate is used to press down on multiple wedge-shaped blocks 12, forcing the multiple wedge-shaped blocks 12 to move into multiple groove seats 13. At the same time, multiple wave springs 15 are fully compressed, and multiple elastic sponge blocks 14 are also compressed. Then, the aluminum alloy connecting groove seat 5 is quickly fitted into the protruding surface of the aluminum alloy protrusion 9, and the outer thin plate is pulled out until the aluminum alloy connecting groove seat 5 is fully fitted into the protruding surface of the aluminum alloy protrusion 9. At this time, the left end of the aluminum alloy protrusion 9 is tightly abutting against the waterproof sealing strip 7. The left ends of the two weather-resistant sealing strips 10 are tightly attached to the aluminum alloy connecting groove seat 5. The multiple wedge-shaped blocks 12 will be aligned with the multiple wedge-shaped grooves 8. Utilizing the elasticity of the multiple wave springs 15, the multiple wedge-shaped blocks 12 will be pushed into the multiple wedge-shaped grooves 8 respectively. When the multiple wedge-shaped blocks 12 are fully inserted into the multiple wedge-shaped grooves 8, the multiple wave springs 15 are in a semi-compressed state and have not lost their elasticity. This can prevent the multiple wedge-shaped blocks 12 from loosening and failing when they are inserted into the multiple wedge-shaped grooves 8.
