Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, and more particularly to a roof curtain wall system with a waterproof structure. Background Technology

[0002] A curtain wall is the exterior cladding of a building. It is non-load-bearing and hangs on the building like a curtain, hence the name "curtain wall." It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. A curtain wall consists of panels and a supporting structural system. It is a building envelope or decorative structure that can have a certain degree of displacement relative to the main structure or a certain degree of deformation capacity, and does not bear the load of the main structure. The roof is the uppermost cladding structure of a building and should meet the corresponding functional requirements, providing a suitable internal space environment. Therefore, the roof curtain wall is the uppermost non-load-bearing cladding structure of a building.

It solves the problem of water leakage when rainwater accumulates excessively inside the aluminum columns after the glass curtain wall is directly placed on aluminum columns, causing water to easily seep into the interior through the joints between the aluminum columns and the four glass curtain walls. The structure includes: aluminum columns, glass curtain walls, and aluminum pressure plates. It also includes four corner molded sealing members disposed on the side of the aluminum columns near the glass curtain walls. The corner molded sealing members abut against the glass curtain wall at the edge near the glass curtain wall, and abut against the aluminum pressure plate at the edge away from the glass curtain wall. A snap-fit ​​post is integrally provided on the edge of the aluminum column near the glass curtain wall, and a snap-fit ​​groove is provided on the side of the corner molded sealing members near the aluminum column for the snap-fit ​​post to snap into.

[0005] With the changing times and rising aesthetic standards, homeowners have increasingly higher requirements for proposed buildings, not only specifying acceptance criteria for practicality but also constantly pursuing breakthroughs in aesthetics. Compared to conventional, regularly shaped roof curtain wall systems, more and more irregularly shaped roof curtain wall systems are being designed. However, to achieve the irregular structures (such as curves) of these systems, multiple panel splicing methods are often needed to address structural twisting and other issues. This inevitably increases the number of seams, thus increasing the risk of leakage. Furthermore, for ventilation and smoke extraction purposes, controllable opening covers are usually installed on the roof curtain wall system. However, due to the irregular structure and / or design requirements, designers may choose unconventional opening covers. Compared to conventional opening covers, unconventional opening covers present greater challenges in waterproofing.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention discloses a roof curtain wall system with a waterproof structure, or a roof curtain wall system with an irregular shape, to solve at least some of the above-mentioned technical problems.

[0008] This invention discloses a roof curtain wall system with a waterproof structure, which includes several modular units that can be assembled in an orderly manner.

[0009] The modular unit includes a top plate laid along the extension direction of the longitudinal pipes on a frame structure constructed of several horizontal and vertical pipes, with the horizontal pipes serving as support beams. Any top plate laid on the longitudinal pipes with an arcuate extension direction can be arranged such that at least part of the structure has a drop relative to other adjacent top plates to form an arcuate structure with a corresponding slope. The drainage channel of the arcuate structure includes a side ditch provided on the side of the longitudinal pipe, wherein the side ditch is provided at least on the side of the longitudinal pipe corresponding to the arcuate inner side of the arcuate structure.

[0010] This design allows water falling onto the roof and curtain wall system due to rainfall and other factors to be quickly drained, preventing excessive water accumulation from putting pressure on the system and reducing the risk of leakage. Compared to designs where the inner ring is lower than the outer ring, this design disperses water that is prone to accumulating outwards rather than inwards, thus achieving rapid drainage.

[0011] Existing building roof support structures typically have a certain curvature, especially for large buildings. The height of the roof support structure gradually decreases from the center of the building outwards, forming a roof support structure arrangement that is high in the middle and low around the edges. For example, CN217128778U discloses a roof system, including a roof body and a top cover. The roof body has a top wall with an opening. The top cover covers the opening and is formed by arranging and splicing multiple top cover units around the center of the opening. Each top cover unit includes a main body, a first drainage channel, and a blocking member. On one side of the main body arranged circumferentially around the center of the opening, the first drainage channel is provided, extending along one side. On the other side, the blocking member extends along the other side. In two adjacent top cover units, the blocking member of one top cover unit covers the first drainage channel of the other top cover unit. This technical solution uses an irregularly shaped top cover to conform to the orientation of the supporting structure. If glass is used as the material for the top cover, it will undoubtedly significantly increase the design, processing, and installation difficulty of the top cover structure. Unlike the prior art, the top plate structures in the modular units of this invention are all planar structures, and it is not necessary to manufacture the top plate structure as an irregularly shaped plane to adapt to the orientation of the curved supporting structure. Therefore, based on the above differences, the technical problem to be solved by this invention is how to reduce the difficulty of installing irregularly shaped top plate structures on curved supporting structures. Specifically, this invention uses horizontal pipes as supporting beams on a frame structure constructed of several horizontal and vertical pipes, and lays planar top plates along the extension direction of the vertical pipes. Any top plate laid on the vertical pipe with a curved extension direction can be set in such a way that at least part of the structure has a height difference relative to other adjacent top plates, thereby compensating for the spatial height difference in the curved extension direction by installing the top plates in a stepped manner.

[0012] According to a preferred embodiment, the mounting section of the modular unit configuration includes a first mounting component connected to a first top plate, a second mounting component connected to a second top plate, and a third mounting component connected to the second mounting component, wherein the second top plate can be arranged such that at least part of its structure extends beyond the plane of the first top plate to form adjacent top plates with a height difference.

[0013] Irregularly shaped structures (such as curved structures with a certain height difference) designed to meet design requirements often face challenges during construction that far exceed those encountered with conventional structures. The structural distortion problem frequently encountered during the construction of curved glass structures with a certain height difference can be solved by the modular units proposed in this invention. By orderly splicing and fixing multiple modular units to the main steel structure, an irregularly shaped roof curtain wall system can be formed. This modular unit not only solves the structural distortion problem by utilizing the overlapping of top slabs, but also reduces or avoids the risk of leakage at the joints through its special waterproof structure.

[0014] According to a preferred embodiment, the second mounting assembly includes two mounting pieces arranged in parallel along its length with non-uniform widths, and the widths of the two pieces change linearly along their length. The mounting pieces of the third mounting assembly can be installed by cooperating with the mounting pieces of the second mounting assembly. Based on the aforementioned technical features that differentiate it from the prior art, the technical problem this embodiment aims to solve is the installation of a stepped roof structure. Specifically, the mounting piece structure of the present invention, with its non-uniform widths arranged in parallel along its length, enables the positioning and installation of the roof structure. Furthermore, it creates a rainwater collection path with linearly varying height on the side of the roof, facilitating the rapid drainage of rainwater from the roof into the side ditch of the longitudinal pipe.

[0015] According to a preferred embodiment, the support portion of the modular unit configuration can clamp the locking tabs of the first and third mounting components through the cooperation of the pressure plate and the base plate, so that the mounting portion is detachably fixed to the support portion. Preferably, the pressure plate and the locking tab abut in an approximately "line contact" manner. This line contact installation method is to avoid connecting the pressure plate and the locking tab into a "one-piece" structure that cannot undergo slight deformation. Due to the large temperature difference throughout the year, especially in areas with rain and snow in winter, the materials of the mounting structure are subject to thermal expansion and contraction. If a one-piece connection structure is directly used, it will generate a certain stress impact on the connection part, which will lead to damage at the connection point. Existing connection methods face the problem of how to solve the deformation of the connection material due to thermal expansion and contraction. The support part of the present invention can clamp the locking pieces of the first and third mounting components through the cooperation of the pressure plate and the base plate. The line contact abutment of the pressure plate and the locking piece can provide a certain degree of freedom of movement for the deformation of the material under thermal expansion and contraction, and can also provide sufficient contact distance at the connection to prevent the pressure plate and the locking piece from separating as a whole, thereby improving the connection stability and safety of the mounting part.

[0016] According to a preferred embodiment, the mounting part can indirectly contact the support part through a seal provided on the base plate. Based on the seal, the pressure plate, when fixing the engaging piece to the base plate, can form four mutually isolated spaces on the base plate, serving as a water collection trough that can connect to the side ditch. As is known in the prior art, bolted connections are generally highly susceptible to corrosion, especially crevice corrosion. Crevice corrosion is corrosion that occurs at the gap between two connected components. This localized corrosion can occur in gaps between metal-to-metal connections (such as riveting and bolting), between metals and non-metals, and between deposits on metal surfaces and the metal surface itself. Once even slight corrosion occurs, the intrusion of moisture will quickly lead to more severe corrosion at the connection, ultimately causing the bolted connection to fail. Therefore, the technical problem to be solved by this embodiment of the present invention is how to improve the corrosion resistance of bolted connections. Specifically, the present invention, through the provision of a seal, allows the pressure plate to form four mutually isolated spaces on the base plate when fixing the engaging piece to the base plate. At this point, neither the water accumulated on the top of the roof nor the condensation at the bottom of the roof can enter the internal space of the bolt connection, thus providing a good sealing condition for the bolt connection and improving its corrosion resistance.

[0017] According to a preferred embodiment, the roof curtain wall system can be provided with a number of opening covers with sharp edges in a discontinuous manner in some areas, wherein the opening cover includes a fixed part and a movable part, and the fixed part and the movable part are movably connected by a hinge.

[0018] In this invention, the opening covers on the roof curtain wall system can be set in a discontinuous manner to avoid the formation of water accumulation channels. This is because the waterproofing at the joint of the water accumulation channels between continuously set opening covers is weak and prone to leakage.

[0019] According to a preferred embodiment, a first waterproof component and a second waterproof component are disposed between the first cover plate of the movable component and the fixed component in a counter-misaligned manner. The first waterproof component is disposed on the fixed component, and the second waterproof component is disposed on the first cover plate. The waterproof component includes a main body and an extension portion.

[0020] According to a preferred embodiment, a sealing element is provided on the side of the main body of the first waterproof component facing the first cover plate, so that the first cover plate covered by the extension portion of the second waterproof component contacts the first waterproof component through the sealing element; a sealing element is also provided on the side of the extension portion of the first waterproof component facing the first cover plate, so that the first cover plate covered by the main body of the second waterproof component contacts the first waterproof component through the sealing element. Existing technologies mainly use irregularly shaped connectors to achieve waterproofing at joints. For example, CN207553387U discloses a waterproof structure for a hyperboloid curtain wall, including a first waterproof layer facing the interior and a second waterproof layer facing the exterior. The first waterproof layer includes insulation material and several first panel units fixed to the insulation material, and the second waterproof layer includes several second panel units, several splicing components, and several connectors. This technical solution uses a shielding surface aligned with the splicing seam. When external water enters through the splicing seam, the shielding surface can block most of the water, thereby reducing the probability of water entering the fixed space. However, in this technical solution, the space where the bolts or screws are connected remains open to the outdoor space, failing to achieve waterproofing and making the connection highly susceptible to corrosion failure. Unlike the prior art, this invention features a first waterproof component and a second waterproof component arranged in a staggered, opposing manner between the first cover plate of the movable component and the fixed component. This confines the bolt connection within a waterproof space, improving the connection stability of the bolts and preventing corrosion failure due to water contact.

[0021] According to a preferred embodiment, when the cover is in the closed state, a zigzag-shaped waterproof groove can be formed between the first waterproof component and the second waterproof component based on the sealing effect of the sealant, wherein the waterproof groove can communicate with the side ditch.

[0022] According to a preferred embodiment, the roof curtain wall system is designed and constructed with at least the degree of deformation of the structure affected by thermal expansion and contraction in mind. In this regard, when considering the degree of deformation of any structure under the influence of thermal expansion and contraction, the deformation of local facilities, including the structure, under various temperature conditions can be simulated by using a collision model calculation method, so that the roof curtain wall system can be constructed according to the adjusted design scheme.

[0023] This invention primarily performs collision model calculations based on the thermal expansion and contraction of modular units, covering most of the roof and curtain wall system's structure. Then, it performs independent collision model calculations for specific structures within the roof and curtain wall system (such as operable covers), thus completing a comprehensive simulation of the entire roof and curtain wall system. This approach benefits from the modular units used in this invention, avoiding a single, complete simulation of the entire roof and curtain wall system. Since adjustments to installation location and climate conditions are necessary, traversing all models in each simulation would exponentially increase the computational load and costs. This invention, however, only requires focused simulation of specific parts of the model, fully utilizing available computing power to simulate all possible scenarios, especially various extreme cases, ensuring the stability of the roof and curtain wall system.

Detailed Implementation

[0035] The following is a detailed explanation with reference to the accompanying drawings.

[0036] With the changing times and rising aesthetic standards, homeowners have increasingly higher requirements for proposed buildings, not only specifying acceptance criteria for practicality but also constantly pursuing breakthroughs in aesthetics. Compared to conventional, regularly shaped roof curtain wall systems, more and more irregularly shaped roof curtain wall systems are being designed. However, to achieve the irregular structures (such as curves) inherent in these systems, it is often necessary to use multiple panel splicing methods to address structural twisting and other issues. This inevitably increases the number of seams, thereby increasing the risk of leakage. Therefore, as... Figure 1 As shown, the present invention discloses a roof curtain wall system with a waterproof structure, and more particularly an irregularly shaped roof curtain wall system.

[0037] Preferably, the roof curtain wall system may include an inner ring and an outer ring with different structural designs, wherein the inner ring is closer to the central area of ​​the building than the outer ring. Preferably, both the inner and outer rings can be constructed from a frame structure consisting of several horizontal and vertical tubes, wherein the roof slab can be laid with horizontal tubes as supporting beams along the extension direction of the vertical tubes, and the roof slab can be made of metal, glass, or other commonly used curtain wall materials according to design requirements. Preferably, the height of the inner ring relative to the foundation or ground level can be higher than that of the outer ring, so as to utilize the height difference to divert water falling into the inner ring to the outer ring, thereby preventing water accumulation in the inner ring. Furthermore, both the inner and outer ring sections can be equipped with slopes of a certain gradient, allowing water in either section to flow downstream along the slope's extension direction. The downstream section of the inner ring slope connects to the upstream section of the outer ring slope, enabling water falling on the inner ring to flow from its downstream location to its upstream location using the height difference, and then further downstream along the outer ring slope's extension direction. Additionally, the outer ring section can have multiple downstream slopes, allowing water falling on the entire roof and curtain wall system to be distributed to various downstream slopes, reducing drainage pressure on any single downstream slope.

[0038] This design allows water falling onto the roof and curtain wall system due to rainfall and other factors to be quickly drained, preventing excessive water accumulation from putting pressure on the system and reducing the risk of leakage. Compared to designs where the inner ring is lower than the outer ring, this design disperses water that is prone to accumulating outwards rather than inwards, thus achieving rapid drainage.

[0039] Preferably, irregularly shaped structures designed to meet design requirements (such as arc-shaped structures with a certain height difference) often face challenges during construction that are far more difficult than those encountered with conventional structures. Furthermore, for arc-shaped glass structures with a certain height difference, structural distortion is frequently encountered during construction. This invention proposes a modular unit. By orderly splicing and fixing multiple modular units to the main steel structure, an irregularly shaped roof curtain wall system can be formed. This modular unit not only solves the structural distortion problem by utilizing the overlapping of the top slabs, but also reduces or avoids the risk of leakage at the joints through its special waterproof structure. Preferably, the modular unit can be applied to the outer ring and / or the inner ring.

[0040] Preferably, such as Figures 2-5As shown, the modular unit may include a support portion 100 and a mounting portion 200. The support portion 100 can be used to connect with the main steel structure, thereby providing support for the mounting portion 200 disposed on the support portion 100. Further, the mounting portion 200 may include multiple components, which are respectively disposed on the support portion 100 directly or indirectly, thereby fixing the top plate. Preferably, the first mounting component 210 of the mounting portion 200 can be directly connected to the first top plate 211, and the second mounting component 220 of the mounting portion 200 can be directly connected to the second top plate 221. The second top plate 221 can be disposed such that at least part of its structure extends beyond the plane of the first top plate 211, that is, the second top plate 221 and the first top plate 211 are not coplanar, thereby forming a certain height difference. Preferably, since the modular units can be assembled in an orderly manner, when viewed along their assembly sequence, two adjacent modular units in the same assembly sequence can share a top plate. That is, the first top plate 211 in the modular unit with the earlier assembly sequence is also the second top plate 221 in the modular unit with the later assembly sequence. One side of this top plate is directly connected to the first mounting component 210 in the modular unit with the earlier assembly sequence, and the other side is directly connected to the second mounting component 220 in the modular unit with the later assembly sequence, thereby achieving orderly assembly of multiple modular units. Preferably, the first mounting component 210 and the second mounting component 220 are arranged in a manner that does not directly contact each other to protect the top plate. A sealant 400 can be provided between the separated first mounting component 210 and the second mounting component 220, and a sealant 400 can also be provided between the first mounting component 210 and the first top plate 211, and between the second mounting component 220 and the second top plate 221, to achieve a waterproof function. The sealant 400 can be a double sealant. Furthermore, TPO waterproof membrane can be added to the surface of the transition area between the first top plate 211 and the second top plate 221, as well as to a portion of the first top plate 211 and the second top plate 221, to enhance waterproof performance.

[0041] Preferably, the first mounting component 210 is directly connected to the support portion 100, and the second mounting component 220 is indirectly connected to the support portion 100, so as to achieve a partial height difference between the first top plate 211 and the second top plate 221. Further, the second mounting component 220 can be connected to the support portion 100 indirectly by connecting to the third mounting component 230, wherein the third mounting component 230 can be configured to match the structure of the second mounting component 220, thereby providing a relatively uniform supporting force to the second top plate 221.

[0042] Preferably, the second mounting assembly 220 may include two parallel mounting pieces 240 and a transition piece connected to both mounting pieces 240. The transition piece is orthogonally arranged to the two mounting pieces 240 and positioned between them to form an integral structure. Further, with the bottoms of the two mounting pieces 240 aligned, the top of the mounting piece 240 closer to the first mounting assembly 210 is higher than the top of the mounting piece 240 on the other side, thus covering the side of the second top plate 221. Preferably, the two mounting pieces 240 are arranged with non-equal widths along their length, and their widths can vary linearly along their length with the same slope. Furthermore, for an arc-shaped structure with a certain height difference, the width of the mounting piece 240 of the second mounting assembly 220 on the inner side of the arc is smaller than its width on the outer side of the arc. That is, the width of the mounting piece 240 of the second mounting assembly 220 increases linearly along the length direction from the inner side to the outer side of the arc, thereby allowing the second top plate 221 to have a tendency to tilt towards the inner side of the arc. Preferably, the tilt angle of the mounting piece 240 can be set according to parameters such as the curvature of the designed arc, wherein the greater the curvature of the arc, the greater the tilt angle of the mounting piece 240.

[0043] Preferably, the second mounting component 220 can be fixed to a third mounting component 230 that matches its structure, wherein the effects of thermal expansion and contraction are taken into account during the installation of the second mounting component 220 and the third mounting component 230. Furthermore, a partial space may be reserved between the second mounting component 220 and the third mounting component 230 in at least the width and / or thickness direction of the mounting piece 240, depending on the temperature at the time of installation and the typical temperature range of the building's location. This space accommodates the thermal expansion and contraction of the second mounting component 220 and the third mounting component 230, preventing deformation that could cause structural damage and / or gaps, thereby leading to water leakage.

[0044] Preferably, since the mounting pieces 240 of the second mounting assembly 220 and the third mounting assembly 230 are arranged with non-uniform widths, the mounting pieces 240 can have different widths at different positions in the length direction. Therefore, when the mounting pieces 240 are heated or cooled, the degree of deformation in the width direction varies at different positions in the length direction. When the second mounting assembly 220 and the third mounting assembly 230 are fitted together, the space reserved in the width direction of the mounting pieces 240 is of unequal diameter, which prevents structural damage even when the mounting pieces 240 deform to different degrees in the width direction. Furthermore, the rate of change of the size of the space reserved in the width direction of the mounting pieces 240 is related to the material of the mounting pieces 240 and the value of its tilt angle. Given that the material of the mounting pieces 240 and its tilt angle are determined, the size of the space required at each position can be calculated.

[0045] Preferably, the first mounting component 210 and the third mounting component 230 can be engaged on the support portion 100. Each end of the first mounting component 210 and the third mounting component 230 may be provided with a locking tab 250. The locking tab 250 is fixed by applying opposing forces to both sides of the locking tab 250, thereby fixing the first mounting component 210 and the third mounting component 230 to the support portion 100. Further, a pressure plate 110 and a base plate 120 provided on the support portion 100 can cooperate to apply opposing forces to both sides of the locking tab 250. The base plate 120 can contact the lower side of the locking tab 250 through a sealing member 400, and the pressure plate 110 can contact the upper side of the locking tab 250 under external pressure and apply a force towards the base plate 120 to its upper side, thereby fixing the locking tab 250 between the pressure plate 110 and the base plate 120 of the support portion 100. Preferably, the base plate 120 can be mounted on the horizontal tube, and a portion of the pressure plate 110 can be detachably connected to the base plate 120 to adjust the force applied to both sides of the locking piece 250. Further, based on the sealing element 400, the pressure plate 110 can form four mutually isolated spaces on the base plate 120 when fixing the locking piece 250. These spaces include two external water collection troughs 130 and two internal water collection troughs 130, where leaked water and / or condensed water can be collected in the corresponding water collection troughs 130. The slope of the water collection troughs 130 allows the water in each trough 130 to be uniformly guided to the side ditch 500 mounted on the vertical tube. Preferably, the water collection troughs 130 can be made of aluminum alloy. Preferably, for a roof curtain wall system with an arc-shaped structure having a certain height difference, the two sides of the vertical tube can respectively correspond to the inner arc of one arc structure and the outer arc of another arc structure. Since the height of the inner side of the arc in the same arc structure can be lower than the height of the outer side of the arc, the side ditch 500 can be set at least on the side of the longitudinal pipe corresponding to the inner side of an arc structure to maximize the collection of water on the roof curtain wall system.

[0046] Preferably, the effects of thermal expansion and contraction are taken into account when the first mounting assembly 210 and the third mounting assembly 230 are installed on the support 100. Furthermore, a portion of space may be reserved in the length direction of the mounting piece 240, depending on the temperature at the time of installation and the typical temperature range of the area where the building is located, to accommodate the thermal expansion and contraction of the second mounting assembly 220 and the third mounting assembly 230. More preferably, for the second mounting assembly 220 and the third mounting assembly 230 of the present invention, attention needs to be paid to the thermal expansion and contraction of their locking tabs 250, especially the thermal expansion and contraction of their locking tabs 250 in the thickness direction. Specifically, the locking tabs 250 of the second mounting assembly 220 and the third mounting assembly 230 are provided with the same reserved space so that the two locking tabs 250 have approximately the same direction and degree of thermal expansion and contraction. This avoids a situation where one side is not pressed tightly due to the different degrees of thermal expansion and contraction of the two locking tabs 250 when the pressure plate 110 applies pressure to them. Such a situation of one side not being pressed tightly may not only create gaps, leading to leakage, but may also cause the top plate to loosen, posing a safety hazard.

[0047] Preferably, the irregularly shaped roof curtain wall system may also be equipped with an operable cover 300, particularly in the inner ring, for indoor ventilation and smoke extraction. Since current roof curtain wall systems often have irregular structures, the structure of the operable cover 300 may also be unconventional. For unconventional operable covers 300, especially those with sharp edges, special waterproofing structures are required to prevent leakage. Preferably, the operable cover 300 in the inner ring is typically located upstream of the drainage channel, allowing water within the operable cover 300 to be diverted to the side ditch 500 of the longitudinal pipe. Preferably, in this invention, the operable covers 300 on the roof curtain wall system can be installed discontinuously to avoid the formation of water accumulation channels. This is because the waterproofing at the junction of water accumulation channels between continuously installed operable covers 300 is weak and prone to leakage.

[0048] Preferably, such as Figures 6-8As shown, the opening cover 300 may include a fixed component 310 and a movable component 320. The fixed component 310 may be connected to the main steel structure, and the movable component 320 may be movably connected to the fixed component 310, so that the opening and closing of the opening cover 300 can be achieved through the relative movement of the movable component 320 and the fixed component 310. Preferably, the movable component 320 may include an integrally formed first cover plate 324 and a second cover plate 325, wherein the second cover plate 325 can be disposed below the first cover plate 324 with a cross-sectional area smaller than that of the first cover plate 324. Further, the movable component 320 of the opening cover 300 may be flipped by a hydraulic rod 340, wherein the hydraulic rod 340 may be connected to the second cover plate 325 by screws, so that the first cover plate 324 and the second cover plate 325 may move with the lifting and lowering of the hydraulic rod 340. Preferably, for the triangular opening cover 300, a hydraulic rod 340 can be provided on each of the two sides of the triangular movable part 320, and a hinge 330 can be provided on the side where the hydraulic rod 340 is not provided, so that the movable part 320 of the triangular opening cover 300 can rotate around the pivot of the hinge 330 under the drive of the hydraulic rod 340, thereby realizing the opening and closing of the opening cover 300.

[0049] Preferably, one side of the hinge 330 can be connected to the movable component 320, and the other side can be connected to the fixed component 310, so that the movable component 320 and the fixed component 310 are hinged at the hinge 330. Since the movable component 320 and the fixed component 310 can move relative to each other, the two components cannot achieve seamless contact in a tightly fitted manner. Therefore, a sealed connection between the two can be ensured by providing one or more seals 400 on the movable component 320 and / or the fixed component 310. Preferably, the seals 400 provided on the movable component 320 and / or the fixed component 310 can be silicone rubber sealing strips.

[0050] Preferably, a first waterproof component 311 and a second waterproof component 321 can be provided between the first cover plate 324 and the fixing component 310, so that the waterproof function of the opening cover 300 can be achieved by the cooperation of the first waterproof component 311 and the second waterproof component 321. Preferably, the first waterproof component 311 can be provided on the fixing component 310, and the second waterproof component 321 can be provided on the first cover plate 324. The waterproof components can each include a main body and an extension, and at least the extension can be connected to the corresponding mounting component by bolts or screws. Further, the second waterproof component 321 can also be fixed to the second cover plate 325 by bolts or screws to prevent the second waterproof component 321 from falling off the first cover plate 324. Preferably, a sealing member 400 can be provided on the side of the main body of the first waterproof component 311 facing the first cover plate 324, so that the first cover plate 324 covered by the extension of the second waterproof component 321 can contact the first waterproof component 311 through the sealing member 400. Preferably, a sealing element 400 may be provided on the side of the extension portion of the first waterproof component 311 facing the first cover plate 324, so that the first cover plate 324 covered by the main body portion of the second waterproof component 321 can contact the first waterproof component 311 through the sealing element 400.

[0051] Preferably, the main body of the first waterproof component 311 can be offset from the main body of the second waterproof component 321, so that when the opening cover 300 is in the closed state, based on the sealing effect of the sealing member 400, a waterproof groove 312 with a roughly zigzag (or "Z") structure can be formed between the first waterproof component 311 and the second waterproof component 321. The water collected in the waterproof groove 312 can be diverted to the side ditch 500 and then discharged.

[0052] Preferably, the end of the second waterproof component 321 may be provided with a groove 322 for placing a waterproof strip 323, and the waterproof strip 323, with one end placed in the groove 322, may have its other end connected to the fixing component.

[0053] Preferably, on the side where the hinge 330 is provided, the hinge 330 can be connected to the extension of the second waterproof component 321 through its movable end and to the extension of the first waterproof component 311 through its fixed end, so that the movable end can rotate around the pivot together with the movable component 320.

[0054] This design ensures the integrity and sealing of the corner assembly, allowing for a relatively higher lifting height. For example, the opening cover 300 of this invention can achieve a lifting height of at least 150mm. In contrast, the corner assembly of existing technologies is relatively weak, making it prone to leakage, and its lifting height is too small, resulting in poor ventilation and smoke extraction.

[0055] Preferably, for the opening cover 300, at least the deformation degree of its first waterproof component 311 and second waterproof component 321 relative to the fixed component 310 and the movable component 320, respectively, under the influence of thermal expansion and contraction can be considered. Furthermore, since both the first waterproof component 311 and the second waterproof component 321 include a main body and an extension portion, and the deformation degree of the main body and the extension portion under the influence of thermal expansion and contraction is different, it is necessary to consider the direction and degree of thermal expansion and contraction of the two portions contained in each of the two waterproof components separately.

[0056] Preferably, when considering the degree of deformation of any structure under the influence of thermal expansion and contraction, the present invention can simulate the deformation under various temperature conditions by using a collision model calculation method, and then judge the rationality of the design scheme based on the simulation results.

[0057] Preferably, this invention primarily performs collision model calculations based on thermal expansion and contraction of modular units to cover most of the roof curtain wall system's structure. Then, it performs independent collision model calculations for specific structures within the roof curtain wall system (e.g., the operable cover 300), thus completing a comprehensive simulation of the entire roof curtain wall system. This approach benefits from the modular units used in this invention, avoiding the need for a complete simulation of the entire roof curtain wall system. Since adjustments to installation location and climate conditions are required, traversing all models in each simulation would exponentially increase the computational load and costs. This invention, however, only requires focused simulation of specific models, fully utilizing available computing power to simulate all possible scenarios, especially various extreme cases, ensuring the stability of the roof curtain wall system.

[0058] Preferably, such as Figure 9 As shown, a grate 510 is typically installed downstream of the drainage channel. The grate 510 may be installed only on one side of the side ditch 500, allowing water in the same drainage channel to be collected in one place. More preferably, the grate 510 may be made of stainless steel. Preferably, the grate 510 may have a generally pyramidal structure and may be installed at the downstream end of the side ditch 500, allowing water in the side ditch 500 to flow into the inner cavity of the grate 510. The grate 510 has several openings on its upstream side facing the drainage channel, so that water on the surface of the curved structure can almost all flow into the inner cavity of the grate 510 through the openings due to the slope of the curved structure. Preferably, the dimensions of the grate 510 can be determined based on factors such as rainfall and the curvature of the curved structure. Furthermore, a metal mesh can be installed in the vicinity of the grate 510, especially in the downstream adjacent area of ​​the grate 510, to block snow and prevent snow accumulated on the roof curtain wall from sliding down due to gravity and injuring pedestrians.

[0059] Preferably, the roof curtain wall system may be equipped with various types of sensors at certain locations to acquire data on the current environment in which the roof curtain wall system is located. Furthermore, the roof curtain wall system may be configured with a control unit to generate control commands based on the data acquired by the sensors.

[0060] Preferably, the control unit can be used to regulate the opening and closing timing and / or opening and closing state of the opening cover 300, wherein the opening and closing state of the opening cover 300 includes not only an open state and a closed state, but also a semi-open state at multiple angles. Preferably, the control unit can determine the current wind and rain parameters based on rain sensors and wind speed and direction sensors, and thereby realize the regulation of at least some of the opening covers 300. When the control unit determines that the current roof curtain wall system is in a rainy environment, it can adjust the opening covers 300 at each position to the corresponding opening and closing state based on the current wind speed and direction. Further, the control unit can adjust the opening cover 300 whose opening direction is directly opposite to the current wind direction to the closed state, and can adjust the other opening covers 300 to the corresponding angle of semi-open state according to factors such as the deviation angle of their opening direction from the wind direction, wind speed, and rainfall, so as to minimize the possibility of rainwater directly entering the room from the opening cover 300.

[0061] Preferably, flow sensors may be installed at certain locations on the grate 510 and side ditch 500 of the roof curtain wall system to monitor the drainage status of each drainage channel of the roof curtain wall system. Preferably, not all flow sensors need to be in the active state to save operating costs and reduce the computational load on the control unit. The control unit can generate control commands to activate other flow sensors based on the data collected by some flow sensors. Furthermore, for any drainage channel, at least the flow sensors installed at the grate 510 can be configured to be in the normally active state, so that when the flow at the grate 510 downstream of the drainage channel is abnormal, the control unit can adaptively activate one or more flow sensors in the relatively upstream side ditch 500 to determine the cause of the abnormality. Preferably, when the abnormality is found to be caused by rainwater leakage due to the open cover 300 being in an open or half-open state, the open cover 300 can be driven to adjust to a closed state or reduce the opening angle, and the flow rate of the drainage channel to which other open covers 300 belong can be checked, so as to avoid the control unit making a misjudgment of the current environment of the roof curtain wall system due to abnormal data acquisition by the rainwater sensor and / or wind speed and direction sensor.
