Description

Technical Field

[0001] The invention relates to the field of building curtain wall engineering, in particular to a waterproof glass curtain wall structure of a building facade. Background Art

[0002] The waterproof glass curtain wall structure on the building's facade, as a kind of enclosure structure widely used 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 need to perform high-altitude auxiliary operations on the outside. After the glass curtain wall is installed, construction workers are still required to fill sealant between the glass curtain walls at high altitude.

[0004] High-altitude operations themselves are extremely risky, and not only do they require a lot of time to coordinate construction personnel and prepare professional equipment, but they also require a lot of manpower to ensure that all work is carried out 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, safety accidents such as falls may occur, posing a serious threat to the lives of the construction workers.

[0006] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0012] In one embodiment, the movable support component includes a locking mechanism. The locking mechanism is used to fix the relative positions of the connecting unit and the guiding sleeve.

[0013] In one embodiment, the sealing component includes an elastic sealing element. The cross-section of the elastic sealing element is in an inclined plane or a curved surface. The elastic sealing element is used to achieve a tight connection and efficient sealing between adjacent curtain wall units.

[0014] In one embodiment, the sealing component includes a plurality of deformation cavities. The deformation cavities communicate with the pressure regulating component. The degree of expansion of the deformation cavities is positively correlated with the sealing pressure between adjacent curtain wall units.

[0015] In one embodiment, the pressure regulating component includes a transmission mechanism and a pressure chamber. The pressure chamber changes the internal pressure through the transmission mechanism to drive the deformation cavities to expand or contract.

[0019] In one embodiment, the linkage traction component includes a traction rope. The traction rope is used to drive multiple threaded push rod assemblies to rotate in the same direction by the same angle.

[0020] The beneficial effects of the present invention are as follows: The present invention provides a waterproof glass curtain wall structure for a building facade, comprising: a movable support assembly and a dynamic sealing system. The movable support assembly and the dynamic sealing system are in communication.

[0026] As Figures 1-8 shown, the embodiment of the present invention provides a waterproof glass curtain wall structure for the exterior of a building, which is applicable to various newly built buildings, and is particularly applicable to public buildings such as high-rise office buildings and commercial complexes that have a large-area glass curtain wall requirement.

[0027] The embodiments of the present invention are particularly applicable to buildings with glass curtain wall requirements, but are also applicable to curtain wall buildings made of other materials that require waterproof and airtight performance, such as aluminum plate curtain wall buildings, etc.

[0028] Specifically, as Figures 1-5 shown, the waterproof glass curtain wall structure of the building facade provided by the embodiments of the present invention includes: A movable support assembly 200 and a dynamic sealing system 300. The movable support assembly 200 is fixedly connected to the curtain wall unit 100, used to suspend the curtain wall unit 100 on the building facade and enable the curtain wall unit 100 to slide in the direction towards the interior. The dynamic sealing system 300 is used to ensure the sealing performance between adjacent curtain wall units 100.

[0029] In daily use scenarios, the curtain wall unit 100 is usually suspended and installed on the building facade. When a certain curtain wall unit 100 is damaged or needs to be replaced, the traditional replacement method requires construction workers to hang in the air and apply a force towards the interior direction to the curtain wall unit 100, causing it to fall towards the interior, so as to complete the disassembly. At the same time, in the existing curtain wall structure, after the curtain wall unit 100 is installed, caulking is used from the outside to fill the gaps and isolate water vapor, strengthening the structural sealing performance between the curtain wall units 100. During the process of filling the sealant, it is required that construction workers operate in the high-altitude environment for a long time.

[0030] However, high-altitude operations pose relatively high safety risks. To reduce the time and risks of construction workers working at high altitudes, a movable support assembly 200 is fixedly connected to each curtain wall unit 100, and a dynamic sealing system 300 is arranged between the curtain wall units 100.

[0031] Specifically, when it is necessary to replace and disassemble a specific curtain wall unit 100, the movable support assembly 200 is activated. After driving the curtain wall unit 100 to move a preset distance in the direction towards the interior, construction workers can perform disassembly operations on the curtain wall unit 100 that has moved into place indoors.

[0032] Generally, the movable support assembly 200 can select mechanical components such as track sliders and electric push rods. When these mechanical components work, they rely on their own mechanical power to drive the connected curtain wall unit 100 to move smoothly along the pre-set track.

[0033] The dynamic sealing system 300 includes a sealing component 310. The sealing component 310 maintains the sealing effect between adjacent curtain wall units 100 through its own deformation and provides a supporting role.

[0034] When the sealing assembly 310 expands, it can closely fit the gap between the curtain wall units 100, thereby achieving an efficient sealing effect and effectively blocking external impurities such as rainwater and dust from entering the interior of the curtain wall unit 100.

[0035] 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 amount of the first sealing assembly is greater than that of the second sealing assembly. The first sealing assembly is located on the upper end wall surface and the lower end wall surface of the curtain wall unit 100, and the second sealing assembly is located on the left side wall surface and the right side wall surface of the curtain wall unit 100.

[0036] In the expanded state of the sealing assembly 310, among the two mutually contacting curtain wall units 100, the lower curtain wall unit 100 can further support the upper curtain wall unit 100, making the deformation amount of the first sealing assembly greater than that of the second sealing assembly, thereby further strengthening the stability of the connection part of the adjacent curtain wall units 100 in the vertical direction.

[0037] 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 adjusts the amount of gas in the internal chamber of the sealing assembly 310, and further adjusts the deformation amount of the sealing assembly 310, that is, the degree of expansion.

[0038] When the environment where the curtain wall unit 100 is located changes significantly, such as temperature fluctuations, wind pressure changes, etc., resulting in possible displacements of the curtain wall unit 100 such as expansion and contraction, swinging, etc., the pressure regulating assembly 320 increases or decreases the gas in the sealing assembly 310, driving the sealing assembly 310 to expand or contract, ensuring that the sealing assembly 310 can adapt to the dynamic changes of the curtain wall unit 100 under different working conditions and maintaining the best sealing and supporting state.

[0039] It can be understood that the sealing assembly 310 is made of high-strength and high-elastic rubber or silica gel materials. Such materials have good flexibility and compressive resistance, and can quickly expand or contract according to air pressure changes to achieve good sealing and supporting effects.

[0040] Furthermore, the movable support assembly 200 and the dynamic sealing system 300 are connected.

[0041] Reasonably set gas passages in the dynamic sealing system 300, and set an internal cavity on the movable support assembly 200, so that the shape and size of the internal cavity match the gas passages, and use pipes or interfaces to connect the gas passages and the internal cavity to ensure stable and controllable gas flow.

[0042] The dynamic sealing system 300 realizes the dynamic adjustment of the sealing performance by adjusting the gas pressure in the internal cavity of the movable support assembly 200, thereby changing the deformation of the sealing assembly 310 acting between the curtain wall units 100.

[0043] Thus, by providing the movable support assembly 200, the curtain wall unit 100 originally installed on the exterior of the building can be conveniently transferred indoors, enabling subsequent operations such as demolition of the curtain wall unit 100 to be replaced in a safe indoor environment. By providing the dynamic sealing system 300, it effectively blocks external impurities such as rainwater and dust from invading the interior of the curtain wall unit 100, while making the structure of the curtain wall unit 100 more stable in the vertical direction. This enables construction workers to no longer need to perform multiple high-altitude suspension operations, effectively improving the construction safety and efficiency. The connection between the dynamic sealing system 300 and the movable support assembly 200 effectively simplifies the overall structure of the device, while enhancing the reliability of the waterproof glass curtain wall structure, reducing the manufacturing cost and maintenance difficulty.

[0044] It can be understood that the sealing assembly 310 in the expanded state can enable the lower curtain wall unit 100 to have an additional supporting effect on the upper curtain wall unit 100, strengthening the stability of the curtain wall unit 100 in the vertical direction.

[0045] In one embodiment, as Figures 4-6 shown, the movable support assembly 200 includes a connection unit 210 and a guide sleeve 220, and the connection unit 210 is slidably disposed inside the guide sleeve 220.

[0046] One end of the connection unit 210 is fixedly connected to the curtain wall unit 100, and the other end of the connection unit 210 is embedded in the guide sleeve 220 and can slide along the inner wall of the guide sleeve 220.

[0047] When the curtain wall unit 100 needs to perform a moving action, a relative displacement is generated between the connection unit 210 and the guide sleeve 220, thereby driving the curtain wall unit 100 to complete a translation operation.

[0048] It can be understood that the moving stroke of the curtain wall unit 100 directly depends on the relative moving distance between the connection unit 210 and the guide sleeve 220. In actual application scenarios, when a large-amplitude movement of the curtain wall unit 100 is required, it can be satisfied by appropriately increasing the length of the connection unit 210.

[0049] It should be noted that the gap between the connecting unit 210 and the guiding sleeve 220 needs to be controlled within a reasonable range. If the gap is too small, the sliding friction force between the connecting unit 210 and the guiding sleeve 220 will increase, resulting in stuck sliding; when the gap is too large, the connecting unit 210 and the curtain wall unit 100 are prone to shaking or offset during use, affecting the positioning accuracy of the curtain wall unit 100.

[0050] Thus, by providing the connecting unit 210 and the guiding sleeve 220, it is possible to effectively ensure that the curtain wall unit 100 moves smoothly and precisely.

[0051] In one embodiment, as Figures 4-6 shown, the movable support assembly 200 includes a locking mechanism 230, and the locking mechanism 230 is used to fix the relative positions of the connecting unit 210 and the guiding sleeve 220.

[0052] During the installation process of the curtain wall unit 100, when the connecting unit 210 slides within the guiding sleeve 220 and drives the curtain wall unit 100 to reach the target position, the operator activates the locking mechanism 230, thereby fixing the relative positions of the connecting unit 210 and the guiding sleeve 220.

[0053] It can be understood that the structure of the locking mechanism 230 can adopt structural forms such as mechanical latches, electromagnetic locks, or threaded fasteners. However, these structures should enable the relative positions of the connecting unit 210 and the guiding sleeve 220 to be maintained for a long time. At the same time, during the process of the locking mechanism 230 performing release and locking actions, the smoothness of the actions should be ensured to avoid unnecessary impacts or damages to the curtain wall unit 100 due to improper operation.

[0054] Furthermore, the locking mechanism 230 can be combined with an automated control system to achieve precise control and real-time monitoring of the position of the curtain wall unit 100. At the same time, through sensors and feedback mechanisms, the automated control system can automatically determine whether the curtain wall unit 100 has reached the preset position and timely trigger the action of the locking mechanism 230. This can significantly improve the operation efficiency and enhance the accuracy of position control.

[0055] Thus, through the locking mechanism 230, the connecting unit 210 and the guiding sleeve 220 can be fixed at the preset position, enabling the connecting unit 210 and the guiding sleeve 220 to withstand large external loads or impacts, thereby ensuring that the curtain wall unit 100 does not shift due to the influence of the connecting unit 210 during use.

[0056] In one embodiment, as Figures 4-8 shown, the sealing assembly 310 includes an elastic sealing element 311, and the elastic sealing element 311 is used to achieve a tight connection and efficient sealing between adjacent curtain wall units 100.

[0057] To improve the sealing performance between curtain wall units 100, an elastic sealing element 311 is installed around the outer peripheral wall surface of the curtain wall unit 100, and the cross-section of the elastic sealing element 311 is beveled or curved. When adjacent curtain wall units 100 come into contact with each other, the cross-sections of the elastic sealing elements 311 fit closely together.

[0058] The cross-section of the elastic sealing element 311 forms a progressive pressing interface when adjacent curtain wall units 100 come into contact. Compared with traditional flat sealing rings, a beveled or curved cross-section can increase the contact area between the elastic sealing element 311 and the curtain wall unit 100. The increased contact area can evenly disperse the pressure over the entire cross-sectional area, thereby reducing the pressure per unit area.

[0059] At the same time, when the elastic sealing element 311 is compressed, it will generate a deformation displacement along the normal direction of the cross-section, forming a self-reinforcing sealing system. The greater the pressure on the elastic sealing element 311, the greater the deformation displacement of the elastic sealing element 311 along the normal direction of the cross-section, thereby further improving the sealing performance.

[0060] Furthermore, in actual application scenarios, since the extrusion pressure on the four corner regions of the elastic sealing element 311 is relatively small, the four corner regions can be set as straight-edge structures and protrude slightly compared to the beveled or curved cross-section. Injecting sealant into the four corner regions of the elastic sealing element 311 can further improve the sealing performance between adjacent curtain wall units 100.

[0061] It can be understood that the part where adjacent curtain wall units 100 come into contact can be the elastic sealing element 311, or beveled sealant strips, beveled gaskets and other structures. These structures can be fixedly connected to the curtain wall unit 100 or abutted against the curtain wall unit 100, but these structures should be able to ensure the sealing performance between adjacent curtain wall units 100.

[0062] Thus, by making the cross-section of the elastic sealing element 311 beveled or curved, the contact area between the elastic sealing element 311 and the curtain wall unit 100 is significantly increased, enabling the pressure to be evenly dispersed over 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 the sealing performance.

[0063] In one embodiment, as Figures 4-8 shown, the sealing assembly 310 includes a plurality of deformation cavities 312, and the degree of expansion of the deformation cavities 312 is positively correlated with the sealing pressure between adjacent curtain wall units 100.

[0064] Specifically, the deformation cavity 312 communicates with the pressure regulating component 320. The higher the degree of expansion of the deformation cavity 312, the stronger the sealing effect between the curtain wall units 100.

[0065] When the deformation cavity 312 gradually expands, the pressure exerted on the curtain wall unit 100 also continuously increases, so that the contact between the elastic sealing element 311 and the curtain wall unit 100 becomes closer, strengthening the sealing effect.

[0066] Furthermore, a deformation cavity 312 is provided between each side of the elastic sealing element 311 and the curtain wall unit 100. According to the force-bearing condition of the curtain wall unit 100, the expansion state of the deformation cavity 312 can be set differently, so as to ensure both the sealing performance and the structural stability at the same time.

[0067] Since the upper end of the curtain wall unit 100 bears the gravity and the contact pressure with the elastic sealing element 311 is relatively large. Therefore, the deformation cavities 312 at the upper end and the deformation cavities 312 at the lower end can adopt a higher expansion state to further improve the sealing effect. The degree of expansion of the deformation cavity 312 can offset part of the influence of gravity on the curtain wall unit 100, ensuring that the elastic sealing element 311 is closely attached to the curtain wall unit 100.

[0068] The acting forces on the left end and the right end of the curtain wall unit 100 are relatively small, and the contact pressure with the elastic sealing element 311 is relatively low. Therefore, the deformation cavities 312 at the left end and the deformation cavities 312 at the right end can adopt a smaller expansion state, which can ensure the sealing property while avoiding the structural deformation caused by the over-expansion of the elastic sealing element 311. Moreover, the appropriate expansion state of the deformation cavity 312 helps to maintain the structural stability of the curtain wall unit 100 and prevent the sealing failure caused by uneven expansion.

[0069] It can be understood 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.

[0070] Thus, through the appropriate expansion degree of the deformation cavity 312, the sealing performance can be effectively guaranteed, and at the same time, unnecessary pressure will not be generated on the curtain wall unit 100, ensuring the stability of the waterproof glass curtain wall structure.

[0071] In one of the embodiments, as Figures 4-6 shown, the pressure regulating component 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.

[0072] 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 the linear displacement of the pressure chamber 322.

[0073] The pressure regulating assembly 320 can be installed on the connecting unit 210. A pressure chamber 322 is formed at one end of the connecting unit 210 where it is connected to the guiding sleeve 220. One end of the pressure chamber 322 is connected to the deformation chamber 312, and the inner peripheral wall surface at the other end of the pressure chamber 322 is provided with threads. A threaded push rod assembly 321 that mates with the threads of the pressure chamber 322 is rotatably connected to the pressure chamber 322.

[0074] When it is necessary to adjust the state of the deformation chamber 312, by rotating the threaded push rod assembly 321, the threaded push rod assembly 321 makes an axial movement within the pressure chamber 322, thereby changing the volume of the pressure chamber 322. At a constant temperature, 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. Since the deformation chamber 312 is in communication with 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 performance between the deformation chamber 312 and the curtain wall unit 100.

[0075] Thus, by precisely changing the volume of the pressure chamber 322 by rotating the threaded push rod assembly 321, the gas pressure within the pressure chamber 322 can be accurately adjusted, and further the expansion state of the deformation chamber 312 can be precisely controlled to meet the sealing requirements under different working conditions.

[0076] It can be understood that since the deformation chambers 312 at the upper and lower ends need to provide a relatively large pressure, in order to make the multiple threaded push rod assemblies 321 lie in the same plane, the length of the threaded push rod assemblies 321 connected to the deformation chambers 312 at the left and right ends can be set to be greater than the length of the threaded push rod assemblies 321 connected to the deformation chambers 312 at the upper and lower ends. Thus, when the threaded push rod assemblies 321 connected to the deformation chambers 312 at the upper and lower ends move a greater distance and the threaded push rod assemblies 321 connected to the deformation chambers 312 at the left and right ends move a smaller distance, the multiple threaded push rod assemblies 321 can be in the same plane.

[0077] In one embodiment, as Figures 4-8 shown, the dynamic sealing system 300 includes a synchronous control component, and the synchronous control component is used to coordinate the operation of multiple pressure regulating components to ensure that the deformation amounts of the multiple sealing components 310 are consistent.

[0078] During the operation of the dynamic sealing system 300, thermal expansion and contraction phenomena will occur due to the influence of temperature changes. This thermal expansion and contraction effect will cause the gap between the sealing component 310 and the curtain wall unit 100 to change, thereby affecting its sealing performance. In order to ensure that the dynamic sealing system 300 can maintain good sealing performance in different temperature environments, it is necessary to adjust the multiple pressure regulating components 320.

[0079] Specifically, the synchronization control component includes a linkage traction component 330, and the linkage traction component 330 synchronously drives a plurality of pressure regulating units 320 through rigid connection or flexible transmission. The linkage traction component 330 may use a traction rope as a transmission component.

[0080] A groove is machined on the threaded push rod component 321 of each pressure regulating component 320, and the traction rope is embedded in the groove to achieve a sliding connection with a plurality of threaded push rod components 321. By using the friction force between the traction rope and the groove, when the traction rope moves, it can drive the connected threaded push rod components 321 to rotate synchronously.

[0081] When it is necessary to enhance the sealing performance of the sealing component 310, the traction rope is moved forward by operation. Since the traction rope is connected to a plurality of threaded push rod components 321 through the groove, under the action of the friction force, the forward movement of the traction rope will cause a plurality of threaded push rod components 321 to rotate in the same direction by the same angle. The rotation of the threaded push rod component 321 will change the volume of the pressure chamber 322, thereby adjusting the gas pressure in the pressure chamber 322 and causing the deformation cavity 312 to expand or contract accordingly. Thus, a plurality of pressure regulating components 320 function synchronously, so that the adjustment effects of a plurality of sealing components 310 are kept consistent, and the sealing performance of the entire dynamic sealing system 300 is effectively improved.

[0082] Thus, by setting the synchronization control component, the synchronous control of a plurality of pressure regulating components 320 is realized, and the synchronous and precise adjustment of a plurality of sealing components 310 of the dynamic sealing system 300 is achieved when the temperature changes, so as to maintain a good sealing effect.

[0083] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0084] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
