Description

Technical Field

[0001] This invention relates to the field of building technology, and more particularly to a building glass curtain wall system. Background Technology

[0002] Architectural glass curtain wall systems are installed on the exterior of buildings for decoration and lighting. Current technology requires hoisting mechanisms to lift the glass curtain wall from the exterior of the building to the corresponding floor for installation. This poses significant safety hazards, especially for high-rise buildings, including curtain wall units falling during hoisting, damage from swaying and collisions, and workers falling during installation. Furthermore, the removal of safety measures after installation makes maintenance work on the exterior even more difficult and risky. Additionally, when a few curtain wall units need to be disassembled, repaired, or replaced, current technology requires disassembling all other curtain wall units in the same horizontal row sequentially, installing the disassembled unit, and then reinstalling the other units in the same row, resulting in a cumbersome process. Summary of the Invention

[0003] This invention provides a building glass curtain wall system.

[0004] Specifically, the present invention is achieved through the following technical solution:

[0005] This invention provides a building glass curtain wall system for the exterior of multi-story buildings. The system includes main curtain wall sections and inter-story curtain wall sections. Each main curtain wall section is composed of multiple main curtain wall units joined laterally in a first sealing manner. Each inter-story curtain wall section is composed of multiple inter-story curtain wall units joined laterally in a second sealing manner. The main curtain wall sections are located on the periphery of each floor of the building, and the inter-story curtain wall sections are located on the periphery of the building structure between each floor. Each inter-story curtain wall unit constituting each inter-story curtain wall section corresponds to a main curtain wall unit in the upper or lower main curtain wall sections. The system is spliced ​​using a third and fourth sealing method and connected to the corresponding building structure. The first sealing method allows relative movement between adjacent main curtain wall units in the building's interior and exterior directions, while the second sealing method allows relative movement between adjacent inter-floor curtain wall units in the vertical direction. The third and fourth sealing methods are configured in combination to allow each main curtain wall unit to be separated from adjacent inter-floor curtain wall units in the building's interior direction. This enables the disassembly and assembly of any main curtain wall unit and inter-floor curtain wall unit of the building's glass curtain wall system without moving other curtain wall units in the same horizontal row.

[0006] In some embodiments, the first sealing method includes an elastic compression sealing structure, which is formed by elastic compression of sealing strips on adjacent main curtain wall units in the transverse direction.

[0007] In some embodiments, the number of elastic compression sealing structures is four, one of which is located at the exterior glass of the main curtain wall unit, and the other three are located at the profile of the main curtain wall unit, thereby forming three sealing cavities arranged along the interior and exterior directions of the building between adjacent main curtain wall units.

[0008] In some embodiments, the second sealing method includes a male-female plug-in sealing structure and at least one elastic compression sealing structure. The male-female plug-in sealing structure is formed by the interlocking of the insert strip of one of the adjacent inter-layer curtain wall units with the slot of the other. The elastic compression sealing structure is formed by the elastic compression of the sealing strip on the adjacent inter-layer curtain wall units in the transverse direction.

[0009] In some embodiments, there are two male-female plug-in sealing structures, which are located on the profile of the inter-layer curtain wall unit near the interior side of the building; there are two elastic compression sealing structures, one of which is located on the exterior glass of the inter-layer curtain wall unit, and the other is located on the profile of the inter-layer curtain wall unit near the exterior side of the building, thereby forming three sealing cavities arranged along the interior-exterior direction of the building between adjacent main curtain wall units.

[0010] In some embodiments, the third and fourth sealing methods are configured in combination to allow each main curtain wall unit to be pivotally separated from the adjacent inter-floor curtain wall unit in the direction of the building interior.

[0011] In some embodiments, one of the third and fourth sealing methods includes a male-female plug-in sealing structure, wherein the plug strip of one of the adjacent main curtain wall units and the inter-layer curtain wall units is plugged into the slot of the other to form the pivot portion of the pivoting method; the other of the third and fourth sealing methods includes an overlapping sealing structure, wherein the sealing strip of one of the adjacent main curtain wall units and the inter-layer curtain wall units overlaps with the profile of the other in the direction of the building exterior to form the opening portion of the pivoting method.

[0012] In some embodiments, a first drainage structure is provided at the top of the main curtain wall row, spanning the splicing gap between adjacent main curtain wall units. The first drainage structure corresponds to a pair of adjacent inter-floor curtain wall units above, thereby enabling water between the pair of adjacent inter-floor curtain wall units above to be guided to the first drainage structure and discharged from the building curtain wall system; and / or, a second drainage structure is provided at the top of the inter-floor curtain wall row, spanning the splicing gap between adjacent inter-floor curtain wall units. The second drainage structure corresponds to a pair of adjacent main curtain wall units above, thereby enabling water between the pair of adjacent main curtain wall units above to be guided to the second drainage structure and discharged from the building curtain wall system.

[0013] In some embodiments, the first drainage structure includes an inner drainage board and a first outer drainage board. The inner drainage board is installed at the bottom of the inter-floor curtain wall unit and near the interior area of ​​the building, and the first outer drainage board is installed at the bottom of the inter-floor curtain wall unit and near the exterior area of ​​the building. The inner drainage board is Z-shaped and the first outer drainage board is L-shaped. The baffle portion of the Z-shaped board near the interior of the building extends upward and the baffle portion of the Z-shaped board near the exterior of the building extends downward. The baffle portion of the L-shaped board near the interior of the building extends upward. The drainage surface of the inner drainage board is higher than that of the first outer drainage board, so that water can be guided from the inner drainage board through the baffle portion of the Z-shaped board near the exterior of the building to the first outer drainage board and discharged from the building curtain wall system.

[0014] In some embodiments, the second drainage structure includes an inner drainage channel and a second outer drainage plate. The inner drainage channel is installed on top of the inter-floor curtain wall unit and near the interior side of the building. The second outer drainage plate is installed on top of the inter-floor curtain wall unit and near the exterior side of the building. The second outer drainage plate is L-shaped, with the baffle portion of the L-shape near the interior side of the building extending upward. The drainage surfaces of the inner drainage channel and the second outer drainage plate extend downward from the interior side of the building towards the exterior side of the building. A through hole is provided between the channel wall of the inner drainage channel and the baffle portion of the second outer drainage plate, so that water can be guided from the inner drainage channel through the through hole to the second outer drainage plate and discharged from the building curtain wall system.

[0015] According to embodiments of the present invention, since the first sealing method allows relative movement between adjacent main curtain wall units in the building's interior and exterior directions, and the third and fourth sealing methods cooperate to allow each main curtain wall unit to be separated from adjacent inter-floor curtain wall units in the building's interior direction, when any main curtain wall unit needs to be disassembled or installed, the operator only needs to stand inside the building to operate the target main curtain wall unit for disassembly and installation. Furthermore, since the second sealing method allows relative vertical movement between adjacent inter-floor curtain wall units, when any inter-floor curtain wall unit needs to be disassembled or installed, the operator only needs to disassemble the main curtain wall unit above or below it, and then stand inside the building to move the inter-floor curtain wall unit to the position of the main curtain wall unit for disassembly and installation. The entire process does not require moving other curtain wall units in the same horizontal row, simplifying the operation. At the same time, during installation, the construction personnel only need to transport the curtain wall units to each floor of the building beforehand and complete the installation of the curtain wall units from inside the building, eliminating the need for hoisting the curtain wall units and avoiding the need for construction personnel to be suspended outside the building for installation work, greatly improving safety.

[0028] The invention will now be described with reference to several embodiments. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and thus implement the invention, and are not intended to imply any limitation on the scope of the invention.

[0029] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to"; the terms "embodiment" and "one embodiment" are to be interpreted as "at least one embodiment"; the term "another embodiment" is to be interpreted as "at least one other embodiment"; the terms "first," "second," etc., may refer to different or the same objects; the term "setup" is not limited to direct or indirect connections, nor to specific connection methods. Other explicit and implicit definitions may also be included below.

[0030] Specific numerical values ​​or ranges may be referred to in the following description. It should be understood that these values ​​and ranges are merely exemplary and may be helpful in putting the ideas of the invention into practice. However, the description of these examples is not intended to limit the scope of the invention in any way. These values ​​or ranges may be set differently depending on the specific application scenario and requirements.

[0031] As mentioned above, existing architectural glass curtain wall systems present safety hazards during installation, construction, and maintenance, and the disassembly and assembly processes are cumbersome when repairs or replacements are needed. The architectural glass curtain wall system proposed in the embodiments of this invention at least partially solves the above-mentioned problems. The following will refer to... Figures 1 to 8 This describes the structure and working principle of an architectural glass curtain wall system according to an exemplary embodiment of the present invention. For example... Figures 1-8 As shown, the building glass curtain wall system of this embodiment generally includes main curtain wall rows and inter-floor curtain wall rows. Each main curtain wall row is composed of multiple main curtain wall units 20 spliced ​​horizontally, and each inter-floor curtain wall row is composed of multiple inter-floor curtain wall units 10 spliced ​​horizontally. Each main curtain wall unit 20 is installed on the periphery of each floor of the building, so that each main curtain wall row protects the opening of each floor of the building. Each inter-floor curtain wall unit 10 is installed on the periphery of the building structure between adjacent floors of the building, so that each inter-floor curtain wall row protects the building structure. That is to say, in the building glass curtain wall system of this embodiment, the inter-floor curtain wall units 10 and the main curtain wall units 20 are arranged alternately vertically.

[0032] like Figure 5 As shown, the inter-layer curtain wall unit 10 is installed on the building structure via connectors. In one embodiment, the main curtain wall unit 20 is installed on the building structure from above via hangers and from below via connectors. In another embodiment, the main curtain wall unit 20 is embedded in the profiles of the adjacent inter-layer curtain wall units 10 above and below in a horizontally sliding manner. In this case, the main curtain wall unit 20 does not need to be directly connected to the building structure.

[0033] Within each main curtain wall row, multiple main curtain wall units 20 are arranged horizontally, and adjacent main curtain wall units 20 are spliced ​​together to form a horizontal splice joint. The horizontal splice joint is sealed by a first sealing method. The first sealing method not only creates a seal between the interior and exterior of the building, but also allows relative movement between adjacent main curtain wall units 20 in the interior and exterior directions of the building.

[0034] In one embodiment, the first sealing method includes an elastic compression sealing structure, which is formed by elastic compression of the sealing strips on the adjacent main curtain wall units 20 in the transverse direction. That is, the vertical profile sides of the adjacent main curtain wall units 20 are respectively equipped with corresponding sealing strips, and the corresponding sealing strips are elastically compressed and deformed to form a sealing structure, and will not hinder the relative movement of the main curtain wall units 20 in the indoor and outdoor directions of the building.

[0035] In one embodiment, such as Figure 3 As shown, the first sealing method employs a four-layer elastic compression sealing structure. A main sealing strip 31 is located at the glass joint along the transverse splice; a secondary sealing strip 32 is located near the interior side of the profile along the transverse splice; and a main sealing strip 31 is located in the middle region of the profile along the transverse splice. A secondary sealing strip 32 is also placed between two main sealing strips 31, forming three sealing cavities. The main sealing strip 31 has a large cross-sectional size and complex shape, achieving better watertightness and airtightness under compression deformation. The four sealing strips form three sealing cavities a, b, and c, which are respectively a watertight cavity, an airtight cavity, and a reinforcement cavity. Due to the influence of outdoor wind pressure, the outdoor air pressure is higher than that in sealing cavity a, causing some rainwater to enter. Since the pressure in the three sealing cavities is equal, rainwater in sealing cavity a will not enter sealing cavity b. Therefore, the main function of sealed cavity b is to form an airtight barrier layer, preventing gas from entering the room through sealed cavity b. In this embodiment of the invention, a further sealed cavity c is added, mainly because this system is a mating system (distinct from the interlocking system of interlayer units). During use, mating systems may experience insecure mating; therefore, sealed cavity c is added to further ensure airtightness.

[0036] In each inter-floor curtain wall row, multiple inter-floor curtain wall units 10 are arranged horizontally, and adjacent inter-floor curtain wall units 10 are spliced ​​together to form a horizontal splice joint. The horizontal splice joint is sealed by a second sealing method. The second sealing method not only creates a seal between the interior and exterior of the building, but also allows for relative vertical movement between adjacent inter-floor curtain wall units 10.

[0037] In one embodiment, the second sealing method includes a male-female plug-in sealing structure and an elastic compression sealing structure. The male-female plug-in sealing structure is formed by the interlocking of the insert of one of the adjacent inter-layer curtain wall units 10 with the slot of the other. Since the insert is sealed to the side wall of the slot through elastic strips on both sides, and the insert and the slot form a 180-degree bending path, it can provide sufficient water tightness. Combined with the elastic compression sealing structure, it can ensure the sealing performance without hindering the vertical relative movement of the inter-layer curtain wall units 10.

[0038] In one embodiment, such as Figure 4 As shown, the second sealing method uses two male-female plug-in sealing structures and two elastic compression sealing structures. A main sealing strip 31 is installed at the transverse joint where the glass is located; a plug slot 33 is installed at the transverse joint near the interior side of the profile; and another plug slot 33 is installed at the transverse joint in the middle area of ​​the profile. A secondary sealing strip 32 is also installed between the plug slot 33 and the main sealing strip 31. In this embodiment, the four sealing strips form three sealing cavities a, b, and c, and the working principle is similar to... Figure 3 Same example.

[0039] In another embodiment, the second sealing method may also include only an elastic compression sealing structure. In this case, since there is no obstruction from the male and female plug-in sealing structure, the adjacent inter-floor curtain wall units 10 can also move relative to each other in the building's interior and exterior directions.

[0040] Between adjacent inter-story curtain wall units 10 and main curtain wall units 20, each inter-story curtain wall unit 10 is spliced ​​with the upper main curtain wall unit 20 to form a vertical splicing seam, which is sealed using a third sealing method. Similarly, each inter-story curtain wall unit 10 is spliced ​​with the lower main curtain wall unit 20 to form a vertical splicing seam, which is sealed using a fourth sealing method. These third and fourth sealing methods, while creating a seal between the building's interior and exterior, also allow the main curtain wall unit 20 to be disassembled from the adjacent inter-story curtain wall unit 10 towards the building's interior, enabling construction workers to remove the main curtain wall unit 20 from inside the building.

[0041] In one embodiment, each main curtain wall unit 20 can be pivotally separated from the adjacent inter-floor curtain wall unit 10 towards the building interior. Specifically, as shown below... Figure 7 As shown, the third sealing method adopts a male-female plug-in sealing structure, wherein the plug slot 33 of the main curtain wall unit 20 and the inter-layer curtain wall unit 10 are formed by the male-female plug-in sealing structure, thereby forming a pivot part; as Figure 6As shown, the fourth sealing method employs an overlapping sealing structure. This structure allows the sealing strip of the main curtain wall unit 20 to overlap the profile of the inter-floor curtain wall unit 10 towards the exterior of the building, thus forming an opening. With the third and fourth sealing methods working in conjunction, an operator standing inside the building can pull the upper part of the main curtain wall unit 20 towards the interior, allowing the main curtain wall unit 20 to pivot around the pivot point towards the interior, thereby disassembling or reversing the installation of the main curtain wall unit 20.

[0042] According to an embodiment of the building glass curtain wall system of the present invention, in an embodiment where the main curtain wall unit 20 is directly connected to the building structure, such as... Figure 1 As shown, when any inter-floor curtain wall unit 10 needs to be disassembled, only the main curtain wall unit 20 below the inter-floor curtain wall unit 10 needs to be disassembled. The operator can then move the inter-floor curtain wall unit 10 downwards and disassemble it from inside the building. In embodiments where the main curtain wall unit 20 is horizontally pushed and pulled into the profiles of adjacent inter-floor curtain wall units 10 above and below, and is not directly connected to the building structure, such as... Figure 2 As shown, when it is necessary to dismantle any inter-floor curtain wall unit 10, only the main curtain wall unit 20 above the inter-floor curtain wall unit 10 to be dismantled needs to be dismantled. The operator can then move the inter-floor curtain wall unit 10 upwards and dismantle it from inside the building.

[0043] The architectural glass curtain wall system of this invention can also form an independent unit-based drainage system. Outdoor rainwater seeps into the interior through the transverse joints between adjacent main curtain wall units 20 and between adjacent inter-floor curtain wall units 10. As mentioned earlier, due to the sealed structure formed within the transverse joints, rainwater flows downwards along the constructed sealed cavity. Specifically, as... Figure 8 As shown, a first drainage structure is provided across the transverse splice joint between adjacent main curtain wall units 20. This first drainage structure guides rainwater from the transverse splice joint of the adjacent upper inter-floor curtain wall unit 10 to the top profile of the main curtain wall unit 20 and discharges it outdoors via route 1, preventing rainwater from continuing to flow downwards into the transverse splice joint between adjacent main curtain wall units 20. A second drainage structure is provided across the transverse splice joint between adjacent inter-floor curtain wall units 10. This second drainage structure guides rainwater from the transverse splice joint of the adjacent upper main curtain wall unit 20 to the top profile of the inter-floor curtain wall unit 10 and discharges it outdoors via route 2, preventing rainwater from continuing to flow downwards into the transverse splice joint between adjacent inter-floor curtain wall units 10.

[0044] In one embodiment, such as Figure 6As shown, the first drainage structure includes an inner drainage board 41 and a first outer drainage board 42. The inner drainage board 41 is installed at the bottom of the inter-story curtain wall unit 10 and near the interior side of the building. The first outer drainage board 42 is installed at the bottom of the inter-story curtain wall unit 10 and near the exterior side of the building. The inner drainage board 41 is Z-shaped, and the first outer drainage board 42 is L-shaped. The Z-shaped baffle portion near the interior side of the building extends upward, the Z-shaped baffle portion near the exterior side of the building extends downward, and the L-shaped baffle portion near the interior side of the building extends upward. The drainage surface of the inner drainage board 41 is higher than that of the first outer drainage board 42, thereby guiding water from the inner drainage board 41 through the Z-shaped baffle portion near the exterior side of the building to the first outer drainage board 42 and out of the building curtain wall system. It should be noted that the dimensions of the inner drainage board 41 and the first outer drainage board 42 in the horizontal direction only need to be set as a single-piece structure, as long as the inner drainage board 41 and the first outer drainage board 42 can cover the horizontal splicing seam between adjacent main curtain wall units 20. For example, to prevent rainwater from flowing laterally out of the inner drainage plate 41 and the first outer drainage plate 42, sealing structures are filled at both ends of the inner drainage plate 41 and the first outer drainage plate 42 to seal them.

[0045] In one embodiment, the pad 45 is disposed below the inner drainage plate 41 as a waterproof block.

[0046] In one embodiment, such as Figure 7 As shown, the second drainage structure includes an inner drainage channel 44 and a second outer drainage plate 43. The inner drainage channel 44 is installed on the top of the inter-floor curtain wall unit 10 and near the interior side of the building. The second outer drainage plate 43 is installed on the top of the inter-floor curtain wall unit 10 and near the exterior side of the building. The second outer drainage plate 43 is L-shaped, with the baffle portion of the L-shape near the interior side of the building extending upward. The drainage surfaces of the inner drainage channel 44 and the second outer drainage plate 43 extend downward from the interior side of the building towards the exterior side of the building. A through hole is provided between the channel wall of the inner drainage channel 44 and the baffle portion of the second outer drainage plate 43, so that water can be guided from the inner drainage channel 44 through the through hole to the second outer drainage plate 43 and discharged from the building curtain wall system.
