[0002] The waterproof glass curtain wall structure on the building's facade, as a widely used enclosure structure in modern buildings, has many advantages such as beautiful appearance and good lighting, and can significantly enhance the overall image and user experience of the building.

[0003] However, when a piece of glass in the glass curtain wall is damaged and needs to be replaced, it is inevitable that construction workers will need to perform auxiliary work at high altitude on the outside. After the glass curtain wall is installed, construction workers still need to fill sealant between the glass curtain walls at high altitude.

[0004] High-altitude operations are inherently extremely risky and require not only a significant amount of time to coordinate construction personnel and prepare specialized equipment, but also a significant amount of manpower to ensure that all work proceeds in an orderly manner.

[0005] Construction workers working at heights often need to perform delicate operations on a narrow and unstable work platform tens or even hundreds of meters above the ground. If they are not careful, they may fall or suffer other safety accidents, posing a serious threat to the lives of the construction workers.

[0039] like Figures 1-8 As shown, an embodiment of the present invention provides a waterproof glass curtain wall structure for a building facade, which is suitable for various new buildings, especially for public buildings such as high-rise office buildings and commercial complexes that require large-area glass curtain walls.

[0040] The embodiments of the present invention are particularly suitable for buildings requiring glass curtain walls, but are also suitable for buildings requiring waterproof and airtight performance and using curtain walls made of other materials, such as aluminum curtain wall buildings.

[0041] Specifically, such as Figure 1-Figure 5 As shown, the waterproof glass curtain wall structure of the building facade provided by the embodiment of the present invention includes:

[0042] The movable support assembly 200 and dynamic sealing system 300 are fixedly connected to the curtain wall unit 100, used to suspend the curtain wall unit 100 from the building facade and enable the curtain wall unit 100 to slide toward the interior. The dynamic sealing system 300 is used to ensure the seal between adjacent curtain wall units 100.

[0043] In everyday use, curtain wall units 100 are typically suspended and installed on the exterior facade of a building. When a curtain wall unit 100 becomes damaged or needs to be replaced, the traditional replacement method requires construction workers to hang from a height and apply force toward the curtain wall unit 100, causing it to fall into the room, thereby completing the removal. Furthermore, in existing curtain wall structures, after the curtain wall units 100 are installed, they are glued from the outside to fill gaps, isolate moisture, and strengthen the structural sealing performance between the curtain wall units 100. This process of applying sealant requires construction workers to operate at high altitude for a long time.

[0044] However, working at heights presents a great safety risk. To reduce the time and risk of construction workers working at heights, a movable support assembly 200 is fixedly connected to each curtain wall unit 100, and a dynamic sealing system 300 is provided between the curtain wall units 100.

[0045] Specifically, when a specific curtain wall unit 100 needs to be replaced or disassembled, the movable support assembly 200 is started to drive the curtain wall unit 100 to move toward the indoor direction to a preset distance, and the construction personnel can dismantle the curtain wall unit 100 that has been moved into place indoors.

[0046] Generally, the movable support assembly 200 can be made of mechanical components such as track sliders, electric push rods, etc. When these mechanical components are working, they rely on their own mechanical power to drive the curtain wall unit 100 connected thereto to move smoothly along a pre-set track.

[0047] The dynamic sealing system 300 includes a sealing assembly 310 , which maintains the sealing effect between adjacent curtain wall units 100 and provides support through its own deformation.

[0048] When the sealing assembly 310 expands, it can fit tightly in the gaps between the curtain wall units 100 , thereby achieving an efficient sealing effect and effectively preventing external impurities such as rainwater and dust from entering the interior of the curtain wall units 100 .

[0049] The sealing assembly 310 is located on the outer peripheral wall surface of the curtain wall unit 100, forming a first sealing assembly and a second sealing assembly. The deformation of the first sealing assembly is greater than that of the second sealing assembly. The first sealing assembly is located on the upper and lower end walls of the curtain wall unit 100, and the second sealing assembly is located on the left and right walls of the curtain wall unit 100.

[0050] When the sealing assembly 310 is in an expanded state, the lower curtain wall unit 100 of the two contacting curtain wall units 100 can further support the upper curtain wall unit 100, so that the deformation of the first sealing assembly is greater than the deformation of the second sealing assembly, thereby further strengthening the stability of the connection between the adjacent curtain wall units 100 in the vertical direction.

[0051] The dynamic sealing system 300 further includes a pressure regulating assembly 320 . The sealing assembly 310 is provided with an internal chamber. The pressure regulating assembly 320 regulates the deformation amount, ie, the expansion degree, of the sealing assembly 310 by regulating the amount of gas in the internal chamber of the sealing assembly 310 .

[0052] When the environment in which the curtain wall unit 100 is located undergoes significant changes, such as temperature fluctuations or changes in wind pressure, which may cause the curtain wall unit 100 to produce displacements such as expansion, contraction, and swinging, the pressure regulating assembly 320 drives the sealing assembly 310 to expand or contract by increasing or decreasing the gas in the sealing assembly 310, ensuring that the sealing assembly 310 can adapt to the dynamic changes of the curtain wall unit 100 under different working conditions and maintain the optimal sealing and supporting state.

[0053] It is understandable that the sealing component 310 is made of high-strength, high-elasticity rubber or silicone material. This type of material has good flexibility and pressure resistance, and can quickly expand or contract according to changes in air pressure to achieve good sealing and support effects.

[0054] Furthermore, the movable support assembly 200 is in communication with the dynamic sealing system 300 .

[0055] A gas passage is reasonably set in the dynamic sealing system 300, and an internal cavity is set on the movable support assembly 200 so that the shape and size of the internal cavity match the gas passage. The gas passage and the internal cavity are connected by pipes or interfaces to ensure stable and controllable gas flow.

[0056] The dynamic sealing system 300 adjusts the gas pressure in the internal cavity of the movable support assembly 200 to change the deformation of the sealing assembly 310 acting between the curtain wall units 100, thereby achieving dynamic adjustment of the sealing performance.

[0057] Thus, by providing a movable support assembly 200, the curtain wall unit 100 originally installed on the building facade can be conveniently transferred indoors, so that subsequent operations such as dismantling the curtain wall unit 100 that needs to be replaced can be performed in a safe indoor environment. By providing a dynamic sealing system 300, rainwater, dust and other external impurities are effectively blocked from invading the interior of the curtain wall unit 100, while the vertical structure of the curtain wall unit 100 is made more stable. This eliminates the need for construction workers to perform multiple high-altitude suspension operations, effectively improving the safety and efficiency of construction. The connection between the dynamic sealing system 300 and the movable support assembly 200 effectively simplifies the overall structure of the device, while improving the reliability of the waterproof glass curtain wall structure, it reduces manufacturing costs and maintenance difficulties.

[0058] It is understandable that the sealing assembly 310 in the expanded state can enable the lower curtain wall unit 100 to provide additional support to the upper curtain wall unit 100, thereby enhancing the stability of the curtain wall unit 100 in the vertical direction.

[0059] In one embodiment, Figure 4-Figure 6 As shown, the movable support assembly 200 includes a connecting unit 210 and a guide sleeve 220 , and the connecting unit 210 is slidably disposed inside the guide sleeve 220 .

[0060] One end of the connecting unit 210 is fixedly connected to the curtain wall unit 100 , and the other end of the connecting unit 210 is embedded in the guide sleeve 220 and can slide along the inner wall of the guide sleeve 220 .

[0061] When the curtain wall unit 100 needs to move, a relative displacement occurs between the connecting unit 210 and the guide sleeve 220, thereby driving the curtain wall unit 100 to complete the translation operation.

[0062] It is understood that the travel of the curtain wall unit 100 is directly dependent on the relative travel distance between the connecting unit 210 and the guide sleeve 220. In actual application scenarios, when a larger movement of the curtain wall unit 100 is required, this can be achieved by appropriately increasing the length of the connecting unit 210.

[0063] It should be noted that the gap between the connecting unit 210 and the guide sleeve 220 must be controlled within a reasonable range. If the gap is too small, the sliding friction between the connecting unit 210 and the guide sleeve 220 will increase, causing sliding jams. If the gap is too large, it is easy to cause the connecting unit 210 and the curtain wall unit 100 to wobble or deviate during use, affecting the positioning accuracy of the curtain wall unit 100.

[0064] Therefore, by providing the connection unit 210 and the guide sleeve 220 , it is possible to effectively ensure that the curtain wall unit 100 can achieve smooth and precise movement.

[0065] In one embodiment, Figure 4-Figure 6 As shown, the movable support assembly 200 includes a locking mechanism 230 , which is used to fix the relative positions of the connecting unit 210 and the guide sleeve 220 .

[0066] During the installation of the curtain wall unit 100 , when the connecting unit 210 slides in the guide sleeve 220 and drives the curtain wall unit 100 to the target position, the operator activates the locking mechanism 230 to fix the relative position of the connecting unit 210 and the guide sleeve 220 .

[0067] It is understood that the locking mechanism 230 may employ a mechanical lock, electromagnetic lock, or threaded fastening structure. However, these structures should ensure that the relative position of the connecting unit 210 and the guide sleeve 220 is maintained for a long period of time. Furthermore, the locking mechanism 230 should ensure smooth release and locking to avoid unnecessary impact or damage to the curtain wall unit 100 due to improper operation.

[0068] Furthermore, the locking mechanism 230 can be integrated with an automated control system to achieve precise control and real-time monitoring of the position of the curtain wall unit 100. Simultaneously, through sensors and feedback mechanisms, the automated control system can automatically determine whether the curtain wall unit 100 has reached the preset position and trigger the locking mechanism 230 at the appropriate time. This significantly improves operational efficiency and enhances the accuracy of position control.

[0069] Thus, the locking mechanism 230 enables the connection unit 210 and the guide sleeve 220 to be fixed in a preset position, so that the connection unit 210 and the guide sleeve 220 can withstand a large external load or impact, thereby ensuring that the curtain wall unit 100 will not be offset due to the influence of the connection unit 210 when in use.

[0070] In one embodiment, Figure 4-Figure 8 As shown, the sealing assembly 310 includes an elastic sealing element 311 , which is used to achieve a tight connection and efficient sealing between adjacent curtain wall units 100 .

[0071] To improve the sealing between curtain wall units 100, an elastic sealing element 311 is installed around the outer peripheral wall surface of the curtain wall unit 100. The cross section of the elastic sealing element 311 is inclined or curved. When adjacent curtain wall units 100 are in contact with each other, the cross sections of the elastic sealing element 311 are tightly fitted.

[0072] The cross-section of the elastic sealing element 311 creates a progressively compressed interface between adjacent curtain wall units 100 when in contact. Compared to conventional flat seals, the inclined or curved cross-section increases the contact area between the elastic sealing element 311 and the curtain wall unit 100. This increased contact area evenly distributes pressure across the entire cross-section, thereby reducing the pressure per unit area.

[0073] At the same time, the elastic sealing element 311 will deform and displace along the normal direction of the cross section when subjected to pressure, forming a self-reinforcing sealing system. The greater the pressure on the elastic sealing element 311, the greater the deformation and displacement of the elastic sealing element 311 along the normal direction of the cross section, thereby further improving the sealing performance.

[0074] Furthermore, in practical applications, since the four corners of the elastic sealing element 311 are subject to relatively low extrusion pressure, these corners can be configured as straight-sided structures that slightly protrude compared to the inclined or curved cross-section. Injecting sealant into the four corners of the elastic sealing element 311 can further enhance the sealing performance between adjacent curtain wall units 100.

[0075] It is understood that the contact portion between adjacent curtain wall units 100 may be an elastic sealing element 311, or may be a beveled sealing strip, a beveled sealing gasket, or other structures. These structures may be fixedly connected to the curtain wall unit 100 or may abut against the curtain wall unit 100, but they should be able to ensure sealing between adjacent curtain wall units 100.

[0076] Thus, by making the cross-section of the elastic sealing element 311 an inclined or curved surface, the contact area between the elastic sealing element 311 and the curtain wall unit 100 is significantly increased, allowing the pressure to be evenly distributed across the entire cross-sectional area, thereby reducing the pressure per unit area. In addition, when subjected to pressure, the elastic sealing element 311 can deform and displace along the normal direction of the cross-section, thereby improving sealing performance.

[0077] In one embodiment, Figure 4-Figure 8 As shown, the sealing assembly 310 includes a plurality of deformation cavities 312 , and the expansion degree of the deformation cavity 312 is positively correlated with the sealing pressure between adjacent curtain wall units 100 .

[0078] Specifically, the deformation cavity 312 is communicated with the pressure regulating assembly 320 . The higher the expansion degree of the deformation cavity 312 is, the stronger the sealing effect between the curtain wall units 100 is.

[0079] When the deformation cavity 312 gradually expands, the pressure applied to the curtain wall unit 100 also increases continuously, thereby making the contact between the elastic sealing element 311 and the curtain wall unit 100 closer, thereby enhancing the sealing effect.

[0080] Furthermore, a deformation cavity 312 is provided between each side of the elastic sealing element 311 and the curtain wall unit 100. The expansion state of the deformation cavity 312 can be differentiated according to the stress condition of the curtain wall unit 100, thereby ensuring both sealing performance and structural stability.

[0081] Because the upper end of the curtain wall unit 100 is subject to gravity, the contact pressure between it and the elastic sealing element 311 is relatively high. Therefore, the deformation cavities 312 at the upper and lower ends can be expanded to a greater degree to further enhance the sealing effect. This expansion of the deformation cavities 312 can partially offset the effects of gravity on the curtain wall unit 100, ensuring a tight fit between the elastic sealing element 311 and the curtain wall unit 100.

[0082] The left and right ends of the curtain wall unit 100 are subject to relatively low forces, resulting in relatively low contact pressure with the elastic sealing element 311. Therefore, the deformation cavities 312 at the left and right ends can be slightly expanded, ensuring tightness while preventing structural deformation of the elastic sealing element 311 due to excessive expansion. Furthermore, the proper expansion of the deformation cavities 312 helps maintain the structural stability of the curtain wall unit 100 and prevents seal failure due to uneven expansion.

[0083] It is understandable that the deformation cavity 312 needs to be made of high-pressure-resistant and corrosion-resistant materials to ensure the stability and reliability of gas transmission.

[0084] Therefore, through the appropriate expansion degree of the deformation cavity 312, the sealing performance can be effectively guaranteed while no unnecessary pressure is generated on the curtain wall unit 100, thereby ensuring the stability of the waterproof glass curtain wall structure.

[0085] In one embodiment, Figure 4-Figure 6 As shown, the pressure regulating assembly 320 includes a transmission mechanism and a pressure chamber 322 . The pressure chamber 322 changes the internal pressure through the transmission mechanism to drive the deformation cavity 312 to expand or contract.

[0086] Specifically, the transmission structure includes a threaded push rod assembly 321 , and the rotational motion of the threaded push rod assembly 321 is converted into a linear displacement of the pressure chamber 322 .

[0087] The pressure regulating assembly 320 can be mounted on the connecting unit 210. A pressure chamber 322 is defined at one end of the connecting unit 210 connected to the guide sleeve 220. One end of the pressure chamber 322 is connected to the deformation chamber 312. The inner wall surface of the other end of the pressure chamber 322 is provided with threads. A threaded push rod assembly 321 that matches the threads of the pressure chamber 322 is rotatably connected to the pressure chamber 322.

[0088] When the state of the deformation chamber 312 needs to be adjusted, the threaded push rod assembly 321 is rotated to cause the threaded push rod assembly 321 to move axially within the pressure chamber 322, thereby changing the volume of the pressure chamber 322. Under constant temperature conditions, when the gas volume decreases, the pressure increases. Therefore, when the threaded push rod assembly 321 is rotated forward to reduce the volume of the pressure chamber 322, the gas pressure within the pressure chamber 322 increases accordingly. Because the deformation chamber 312 is connected to the pressure chamber 322, the increased pressure acts on the deformation chamber 312, causing the deformation chamber 312 to expand and deform, thereby improving the sealing between the deformation chamber 312 and the curtain wall unit 100.

[0089] Therefore, by rotating the threaded push rod assembly 321 to accurately change the volume of the pressure chamber 322, the gas pressure in the pressure chamber 322 can be accurately adjusted, and the expansion state of the deformation cavity 312 can be accurately controlled to meet the sealing requirements under different working conditions.

[0090] It can be understood that since the deformation cavities 312 at the upper and lower ends need to provide a larger pressure, in order to make the multiple threaded push rod assemblies 321 located on the same plane, the length of the threaded push rod assembly 321 connected to the deformation cavity 312 at the left and right ends can be set to be greater than the length of the threaded push rod assembly 321 connected to the deformation cavity 312 at the upper and lower ends, so that when the threaded push rod assembly 321 connected to the deformation cavity 312 at the upper and lower ends moves a larger distance and the threaded push rod assembly 321 connected to the deformation cavity 312 at the left and right ends moves a smaller distance, the multiple threaded push rod assemblies 321 can be on the same plane.

[0091] In one embodiment, Figure 4-Figure 8 As shown, the dynamic sealing system 300 includes a synchronous control component, which is used to coordinate the operation of multiple pressure regulating components to ensure that the deformation amounts of multiple sealing components 310 are consistent.

[0092] During operation, the dynamic sealing system 300 expands and contracts due to temperature fluctuations. This expansion and contraction can cause the gap between the sealing assembly 310 and the curtain wall unit 100 to change, thereby affecting its sealing performance. To ensure that the dynamic sealing system 300 maintains good sealing performance under different temperature environments, the multiple pressure regulating assemblies 320 need to be adjusted.

[0093] Specifically, the synchronous control assembly includes a linkage traction assembly 330, which synchronously drives the multiple pressure regulating units 320 through a rigid connection or a flexible transmission. The linkage traction assembly 330 can use a traction rope as a transmission component.

[0094] A groove is machined on the threaded push rod assembly 321 of each pressure regulating assembly 320, and a traction rope is embedded in the groove to achieve a sliding connection with the multiple threaded push rod assemblies 321. Due to the friction between the traction rope and the groove, when the traction rope moves, it can drive the threaded push rod assembly 321 connected to it to rotate synchronously.

[0095] When the sealing performance of the sealing assembly 310 needs to be enhanced, the traction rope is moved forward through operation. Since the traction rope is connected to the multiple threaded push rod assemblies 321 through a groove, under the action of friction, the forward movement of the traction rope will cause the multiple threaded push rod assemblies 321 to rotate in the same direction and at the same angle. The rotation of the threaded push rod assembly 321 will change the volume of the pressure chamber 322, thereby adjusting the gas pressure in the pressure chamber 322, causing the deformation cavity 312 to expand or contract accordingly. As a result, the multiple pressure adjustment assemblies 320 function synchronously, so that the adjustment effect of the multiple sealing assemblies 310 remains consistent, thereby effectively improving the sealing performance of the entire dynamic sealing system 300.

[0096] Therefore, by setting up a synchronous control component, synchronous control of multiple pressure adjustment components 320 is achieved, and the multiple sealing components 310 of the dynamic sealing system 300 are synchronously and accurately adjusted when the temperature changes to maintain good sealing performance.

[0097] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
