Technical Field
[0001] This utility model relates to the field of glass curtain wall technology, and in particular to a connection device for a frameless glass curtain wall. Background Technology
[0002] Glass curtain walls are a widely used exterior envelope structure in modern buildings. With their transparency, aesthetics, and lightweight characteristics, they are widely used in high-rise buildings, commercial complexes, and public facilities. Glass curtain walls can provide good lighting effects while also having functions such as heat insulation, sound insulation, and weather protection. According to the structural form, glass curtain walls can be divided into exposed frame glass curtain walls, concealed frame glass curtain walls, and semi-concealed frame glass curtain walls. Among them, concealed frame and semi-concealed frame glass curtain walls are favored in architectural design due to their simple appearance and high safety.
[0003] Existing glass curtain wall connection devices lack structures capable of filling gaps and clamping the glass curtain wall. When gaps appear between the connection frame and the glass curtain wall, external sealant is usually required. However, the adhesion and durability of sealant are greatly affected by environmental factors, leading to aging, cracking, or peeling, resulting in a decrease in sealing performance. At the same time, although existing connection devices can fix the glass curtain wall, they lack simple and effective drainage structures. In rainy or snowy weather, rainwater or snowmelt easily accumulates inside the connection frame, keeping the glass curtain wall in a humid environment for a long time. As the glass curtain wall is constantly immersed in water, it absorbs a large amount of moisture, resulting in a decrease in overall strength and rigidity.
[0004] Therefore, addressing the problems of existing glass curtain wall connection devices, this utility model adopts an adjustable pressure plate structure. A rotating fixing screw drives the pressure plate to move, pushing the anti-slip pad against the tempered glass surface. A tightening spring applies pressure evenly, effectively filling the gap between the tempered glass and the device, preventing excessive localized stress from affecting the strength of the tempered glass. A limiting rod prevents the tightening spring from shaking or shifting, improving stability. Furthermore, in rainy or snowy conditions, the interlayer between the fixing frame and the drainage plate collects rainwater splashed onto the tempered glass surface and guides the water flow out through the drainage holes using a drainage slope. Simultaneously, the baffle blocks leaves, insects, and other impurities, preventing blockage of the drainage system, thus ensuring smooth drainage and guaranteeing the long-term stable operation of the curtain wall. This optimizes the gap-filling structure and drainage design, improving the stability and durability of the glass curtain wall and connection device. Utility Model Content

However, its adhesion and durability are greatly affected by the environment, and it is prone to aging and falling off. In addition, existing connection devices lack a simple and effective drainage structure. In rainy and snowy weather, water easily accumulates in the connection frame, causing the glass curtain wall to be exposed to a humid environment for a long time, resulting in moisture absorption and reducing its strength and rigidity.

The fixing screw is rotatably connected to the back of the pressure plate and is located at the center of the pressure plate. An anti-slip pad is fixedly connected to the front of the pressure plate and is movably connected to the back of the tempered glass. The anti-slip pad is slidably connected to the inner side wall of the fixing frame.
[0011] Preferably, a fastening spring and a limiting rod are fixedly connected to the back of the pressure plate. The fastening spring and the limiting rod are symmetrically installed near both ends of the pressure plate. The fastening spring is movably sleeved on the outside of the limiting rod. The end of the fastening spring away from the pressure plate is fixedly connected to the inner wall of the fixed frame.

[0012] Preferably, a baffle is fixedly connected to the back of the hydrophobic plate, the baffle is movably connected to the front of the tempered glass, and the baffle is equidistantly installed near the top of the hydrophobic plate.

[0013] The beneficial effects of this utility model are:
[0014] 1. When the device is used to connect tempered glass, the tempered glass is placed on the inner wall of the fixed frame, and the tempered glass is pushed to fit tightly against the connecting rod. The front and rear structural adhesives are applied to the surface of the tempered glass and bonded to it, thus achieving the connection and installation of the tempered glass. The front and rear mounting frames ensure that the tempered glass is in close contact with the front and rear structural adhesives. At the same time, the connecting column and the reinforcing keel enhance the connection stability.

This achieves a stable fixation of the tempered glass and keeps the appearance of the glass curtain wall simple.
[0015] 2. When the device needs to fill the gap between the tempered glass and the glass, rotate the fixing screw to move the pressure plate towards the tempered glass, so that the anti-slip pad is in contact with the tempered glass. At the same time, the tightening spring ensures that the pressure plate can apply pressure evenly, so that the anti-slip pad is fully in contact with the glass surface, thereby ensuring that the gap is effectively filled and avoiding excessive local pressure. Meanwhile, the limiting rod prevents the spring from shaking, thereby improving the stability of the device. This realizes the function of filling gaps without sealant and maintains the structural strength of the tempered glass.
[0016] 3. When the device is used in rainy or snowy weather, rainwater or snow water hits the surface of the tempered glass and flows into the interlayer between the fixed frame and the drainage plate. The water flows along the drainage slope and is discharged through the drainage holes, ensuring that the device drains water quickly and in a timely manner. At the same time, the baffle can block larger impurities such as leaves and insects, preventing the drainage holes from being blocked and ensuring the smooth flow and long-term stable operation of the drainage plate. This prevents the glass curtain wall from being soaked in water for a long time, which would cause a decrease in overall strength and rigidity. Attached Figure Description

The front structural adhesive 202 and the rear structural adhesive 204 bond and fix the tempered glass 1 to both sides, achieving double-sided support, making the force more even, and thus improving the compressive strength.
[0027] A reinforcing keel 301 is fixedly connected to the outer wall of the connecting column 3. The reinforcing keel 301 is fixedly connected to the side of the fixing frame 4. The fixing frame 4 is symmetrically installed on both sides of the reinforcing keel 301. An aluminum alloy column 302 is fixedly connected to the back of the reinforcing keel 301. The reinforcing keel 301 and the aluminum alloy column 302 provide additional support for the connecting column 3, ensuring that the device is not prone to structural deformation during long-term use.
[0028] The fixed frame 4 is internally threaded with a fixing screw 401, which passes through the back of the fixed frame 4. A pressure plate 402 is slidably connected to the inner wall of the fixed frame 4.

The fixing screw 401 can drive the pressure plate 402 to move back and forth, thereby controlling the degree of adhesion of the anti-slip pad 403 to the tempered glass 1, ensuring that the tempered glass 1 is stably installed and not easily loosened.
[0029] A fastening spring 404 and a limiting rod 405 are fixedly connected to the back of the pressure plate 402. The fastening spring 404 and the limiting rod 405 are symmetrically installed near both ends of the pressure plate 402.

The end of the fastening spring 404 away from the pressure plate 402 is fixedly connected to the inner wall of the fixed frame 4. The end of the limiting rod 405 away from the pressure plate 402 is slidably connected to the inside of the fixed frame 4. The fastening spring 404 maintains the balanced force applied to the pressure plate 402 and avoids excessive local force affecting the structural strength of the tempered glass 1.
[0030] A baffle 501 is fixedly connected to the back of the drainage plate 5. The baffle 501 is movably connected to the front of the tempered glass 1.

The drainage slope 502 is movably connected to the front of the tempered glass 1. The drainage slope 502 is fixedly connected to the inner wall of the fixed frame 4. Drainage holes 503 are opened inside the drainage plate 5. The drainage holes 503 are equidistantly distributed near the drainage slope 502 to prevent rainwater from accumulating in the gap between the device and the tempered glass 1, thus realizing the drainage function of the device.
[0031] Working principle: According to Figures 1 to 3 When the device is used to connect tempered glass 1, firstly, the tempered glass 1 is placed on the inner wall of the fixed frame 4. Then, an external force is applied to push the tempered glass 1, causing it to move towards the connecting rod 2 until it is tightly attached to the connecting rod 2. At this time, the front structural adhesive 202 and the rear structural adhesive 204 are attached to the surface of the tempered glass 1 and bonded to it, thus realizing the connection and installation of the tempered glass 1. In addition, the front mounting frame 201 and the rear mounting frame 203 ensure that the tempered glass 1 is in close contact with the front structural adhesive 202 and the rear structural adhesive 204. At the same time, the connecting column 3 enhances the overall connection stability, the reinforced keel 301 further supports the connecting column 3, and the aluminum alloy column 302 provides additional support and is concealed on the back of the tempered glass 1, without affecting the overall appearance of the curtain wall.
[0032] according to Figures 4 to 5 When the device needs to fill the gap between the tempered glass 1, firstly, hold the fixing screw 401 and rotate it with external force to move the pressure plate 402 toward the tempered glass 1 until the anti-slip pad 403 is in contact with the tempered glass 1. At the same time, as the pressure plate 402 moves, the fastening spring 404 is stretched. Under the elastic force of the fastening spring 404, the pressure plate 402 is ensured to apply pressure evenly, so that the anti-slip pad 403 fully adheres to the glass surface, thereby effectively filling the gap and preventing excessive local pressure from affecting the structural strength of the tempered glass 1. In addition, the limiting rod 405 limits the fastening spring 404 to prevent it from shaking or shifting during use, thereby improving the stability of the device.
[0033] according to Figure 5 When the device is used in rainy or snowy weather, firstly, rainwater or snow water hits the surface of the tempered glass 1 and, under the action of gravity, flows into the interlayer between the fixed frame 4 and the drainage plate 5. Then, the water flows along the drainage slope 502 and continues to be discharged through the drainage hole 503 under the action of gravity, ensuring that the device drains water quickly and in a timely manner. At the same time, the baffle 501 can block larger impurities such as leaves and insects, preventing them from entering the interlayer between the fixed frame 4 and the drainage plate 5, thereby avoiding blockage of the drainage hole 503 and ensuring the smooth flow and long-term stable operation of the drainage plate 5.
