Description

Technical Field

[0001] The present application relates to a building curtain wall project, and in particular to a vertical frame shared unit curtain wall and a construction method thereof. Background Art

[0002] The unitized curtain wall is a basic unit of curtain wall structure made of panels and supporting frames in the factory with a height of not less than one floor, which is directly installed on the main structure to form a frame-supported building curtain wall. The sealing method between the vertical frames of the unit panels of the unitized curtain wall is divided into a structure with overlap between the vertical frame profiles and a structure without overlap between the vertical frame profiles. For the overlap structure between the vertical frame profiles, the entire cavity area of ​​the vertical frame profile needs to participate in sealing and drainage, and the depth dimension of the horizontal frame section must be basically flush with the vertical frame. The load between the upper and lower unit panels cannot be transferred through the vertical frame, but can only be transferred through the horizontal frame. The horizontal frame profile is used in large quantities and the cost is high. For the structure without overlap between the vertical frame profiles, the entire cavity area of ​​the vertical frame profile needs to participate in sealing and drainage, and the depth dimension of the horizontal frame is basically flush with the vertical frame. The horizontal frame profile is used in large quantities; the sealing between the unit panels only relies on the rubber strips, and the installation quality of the rubber strips is not easy to check, and the sealing performance is not easy to control. For unitized curtain walls, the main technical issues that need to be solved are to reduce the cavity area where the vertical frame profile participates in sealing and drainage so that the water entering the vertical frame cavity can be discharged in an orderly manner, and to transfer the load between the upper and lower unit panels through the vertical frame.

[0003] There are two main sealing methods between the vertical frames of adjacent unit panels: overlapping between vertical frame profiles and non-overlapping between vertical frame profiles.

[0004] Overlap between vertical frame profiles means that vertical frame profiles of adjacent unit panels are plugged into each other, and the plugged-in parts are sealed with sealing strips to complete the combination. The advantage of this method is that the sealing strips can be compressed by plugging aluminum profiles into each other at the overlapping parts between vertical frame profiles, and the sealing effect is good; if water enters the vertical frame cavity, the water can be discharged to the outside in an orderly manner through the drainage plugs and other structures set at the horizontal frame, and the anti-leakage effect is good. The disadvantage is that the entire cavity area of ​​the vertical frame profile needs to be involved in sealing and drainage, and the cross-sectional depth of the horizontal frame profile needs to be basically flush with the vertical frame due to structural requirements such as waterproofing. The horizontal frame profile is used in large quantities and has high cost; between the upper and lower unit panels, the load can only be transferred through the horizontal frame, and it is difficult to transfer the load directly through the vertical frame, and the load transfer path is not simple enough.

[0005] No overlap between vertical frame profiles means that there is no plug-in between vertical frame profiles of adjacent unit panels, and the plug-in parts are sealed with sealing strips to complete the combination. The advantage of this method is that the load can be transferred between the upper and lower unit panels through the vertical frame. The disadvantage is that the entire cavity area of ​​the vertical frame profile needs to be involved in sealing and drainage, the depth of the horizontal frame is basically flush with the vertical frame, and the amount of horizontal frame profile is large; there is no overlap between the vertical frame profiles, and they are only sealed by strips, which are not easy to check and the sealing performance is not easy to control.

[0036] Secondly, to achieve organized drainage: when water seeps into the joints of the curtain wall, the water can be discharged to the outside of the panel in an orderly manner according to the designed structure and drainage path. Waterproofing and drainage are carried out in the front area of ​​the vertical frame, and the rear area of ​​the vertical frame does not participate in drainage.

[0037] Finally, it is convenient for load transfer: the front area of ​​the vertical frame is used for drainage, and the rear area of ​​the vertical frame can be used to connect the vertical frames of the upper and lower unit plates, simplifying the load transfer path.

[0063] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] The specific structural and functional details disclosed herein are merely representative and are for the purpose of describing exemplary embodiments of the present application. However, the present application may be implemented in many alternative forms and should not be interpreted as being limited to the embodiments described herein.

[0065] It should be understood that, although the terms "first", "second", etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are used only to distinguish one unit from another unit. For example, without departing from the scope of the exemplary embodiments, the first unit may be referred to as the second unit, and similarly the second unit may be referred to as the first unit.

For example, depending on the functions / actions involved, two figures shown in succession may actually be performed substantially simultaneously or may sometimes be performed in the reverse order.

[0068] The structure of the unitized curtain wall according to one embodiment of the present application is as follows: Figures 1 to 4 ,as well as Figures 1A to 1D As shown. The unitized curtain wall 800 in these figures includes two layers of unit panels, each layer of unit panels includes at least two unit panels 100. The unit panels 100 may have the same structure or different structures, such as structures with complementary side frame components. These figures do not fully depict the entire unit panel. For example, the unit panels of the upper layer only depict the lower crossbeam component 32, while the unit panels of the lower layer only depict the upper crossbeam component 31; similarly, on the same layer, only the structure of the junction of the unit panels is depicted, for example, only the auxiliary frame component 10 of the unit panel on the right and the vertical frame structure 20 of the unit panel on the left are depicted, wherein the vertical frame structure includes a front area portion 21 and a rear area portion 22. The specific description of these structures will be expanded below.

[0069] Figures 9 to 16An example of the structure of such a unit panel is shown. The unit panel 100 in the embodiment of the present application may include an outer frame assembly 1 and a panel 2 connected to the outer frame assembly. The outer frame assembly 1 has a structure with complementary side frame components, and includes an auxiliary frame component 10, a vertical frame component 20, and a crossbeam 30 connected to the auxiliary frame component and the vertical frame component. The auxiliary frame component 10 and the vertical frame component 20 can be arranged in parallel, for example, in a manner in which the center lines of the two are parallel. The crossbeam 30 is arranged between the auxiliary frame component 10 and the vertical frame component 20, for example, perpendicular to the two to form an I-shaped outer frame assembly; or the crossbeam 30 includes two, namely an upper crossbeam component 31 and a lower crossbeam component 32, to form a U-shaped outer frame assembly, or has three crossbeams to form a J-shaped outer frame assembly.

[0070] The auxiliary frame member 10 and the vertical frame member 20 both include opposite inner side surfaces, the inner side surfaces include a first inner side surface portion at a first width, and a second inner side surface portion at a second width closer to the front side, i.e., the front side, than the first inner side surface portion, wherein the second width is greater than the first width, the first inner side surface portions are connected to the cross beam 30, and the second inner side surface portions are installed with the panel 2. In this way, the panel can cover at least a portion of the cross beam.

[0071] In the example where the cross beam 30 includes an upper cross beam member 31 and a lower cross beam member 32, Fig.16 As shown, the upper cross beam member 31 may have a lower portion 311 for fixing the panel and an upper portion 312 separated from the lower portion by a bottom plate, wherein the upper portion 312 includes a substantially concave-shaped upper cross beam rear cavity portion 3121 and a substantially L-shaped upper cross beam front cavity portion 3122 separated from the rear cavity portion 3121 by an upper cross beam front side wall 3123. The bottom plate of the front cavity portion 3122 may be formed by extending the bottom plate of the rear cavity portion 3121 forward, and the bottom plate of the front cavity portion may be used as an upper fixing frame for limiting the panel 2.

[0072] The lower cross beam component 32 may have a structure matching the upper cross beam component 31. Fig.16 In the illustrated embodiment, the lower cross beam component 32 includes a lower cross beam main body portion 321 and a lower cross beam front fixing portion 322 spaced apart from the lower cross beam main body portion 321. The lower cross beam front fixing portion 322 forms a lower fixing frame of the panel 2.

[0073] The rear cavity part 3121 of the upper cross beam cooperates with the main part 321 of the lower cross beam component 32 of the unit plate of the upper layer, for example Fig.16As shown, the main body can be sealed with the rear cavity of the upper beam through the sealing members 331 and 332 provided on the rear side wall 3124 of the upper beam, and form a first transverse sealing structure and a second transverse sealing structure. The front cavity 3122 of the upper beam is matched with the front fixing portion 322 of the lower beam member 32 of the unit plate of the upper layer, for example Figure 8 As shown, the sealing member 333 disposed on the front side wall 3123 of the upper cross beam is sealed with the front side wall of the upper cross beam to form a third transverse sealing structure. Among them, the first transverse sealing structure, the second transverse sealing structure and the third transverse sealing structure can ensure that water does not flow directly into the cross beam from these positions, thereby facilitating drainage design.

[0074] A sealing member extending outwardly may be provided on the surface of the lower fixing frame forming the panel 2 which is laterally extended from the front fixing portion 322 of the lower beam, such as a sealing strip 334 which is clamped on the front fixing portion 322 of the lower beam. The sealing strip may form a fourth transverse sealing structure together with the portion of the front side wall 3123 of the upper beam which extends forward.

[0075] There is no special requirement for the thickness of the upper cross beam component 31 and the lower cross beam component 32, that is, the size in the front-back direction. In a preferred embodiment, their thickness is less than the thickness of the first side frame component and the second side frame component. In particular, in the embodiment where the unit plate includes an auxiliary frame component and a vertical frame component, the upper cross beam component 31 and the lower cross beam component 32 are both less than the thickness of the vertical frame component. Such a design can reduce the material consumption of the upper cross beam component and the lower cross beam component.

[0076] Although Fig.16 The upper crossbeam component and the lower crossbeam component are respectively located in different unit plates, but it should be understood that in order to achieve the unification of the unit plates, the upper crossbeam component and the lower crossbeam component can be provided on the same unit plate, so the above description can also be understood as being made for the same unit plate.

[0077] exist Fig. 9 In the illustrated embodiment, the vertical frame member 20 has a front portion 21 and a rear portion 22, which are fixedly connected or integrally formed, wherein the front portion 21 and the rear portion 22 define a frame member receiving portion 23, and the frame member receiving portion 23 is used to cooperate with the frame member 10 of another unit panel when two unit panels are combined, so it can be configured to be basically consistent with the shape of the frame member 10 to completely receive the frame member 10. For example, Figure 1 As shown, the auxiliary frame member receiving portion 23 may include a transverse outward wall 231 and a forward wall 232 of the vertical frame member.

[0078] The rear area 22 can have a rectangular closed cross-sectional structure as shown in the figure, so that even if water breaks through the first and second longitudinal sealing structures, the water will not flow into the rear area 22 and thus flow downward along the rear area, thus avoiding the need for the upper cross beam component and the lower cross beam component of the outer frame assembly to completely wrap the entire front and rear dimensions of the vertical frame in the front and rear directions in order to achieve drainage. At the same time, since the wind load is borne by the side frame part, that is, the vertical frame component and the auxiliary frame component, reducing the size of the upper cross beam component and the lower cross beam component can greatly save the material of the upper cross beam and the lower cross beam while ensuring the resistance to wind load. In some embodiments not shown, the rear area does not need to have a closed cross-sectional structure and can still prevent water from entering the interior of the rear area 22, as long as it is ensured that the wall 232 at the receiving portion 23 of the auxiliary frame component has a closed structure, that is, a closed structure in the front and rear directions is formed between the front area and the rear area and reaches or exceeds the rear cavity portion 3121 of the upper cross beam component in the front and rear directions. For example, the rear area 22 has a concave cross-sectional structure that is open backwards. The cross-sectional shape of the rear portion is not necessarily rectangular or based on a rectangle, and may also be other forms such as polygonal, circular, etc. The closed structure may be a part of the rear portion 22, or a separate part between the rear portion and the front portion.

[0079] In order to achieve the matching of the auxiliary frame component 10 of one unit panel with the vertical frame component 20' of another identical unit panel, and vice versa, the auxiliary frame component 10 is provided with an auxiliary frame connecting surface 101, which can be as follows Figure 1 As shown, it is located on the lateral side of the auxiliary frame member 10, and a first locking device is fixed on the auxiliary frame connecting surface 101, for example, as shown Figure 1 The first hook component 401 is fixed to the attachment frame connection surface by bolts; correspondingly, the vertical frame component 20 includes the vertical frame connection surface 201, corresponding to the position of the vertical frame connection surface, which is also located at the vertical frame component receiving part 23 of the lateral side of the front area part 21; the vertical frame connection surface has a second locking device matching the first locking device 401, for example, a second hook component 402 fixed to the vertical frame connection surface by bolts, and the first hook component 401 and the second hook component 402 are configured so that after the vertical frame component 10 of one unit plate is matched to enter the vertical frame component 20' of the attachment frame component receiving part of another unit plate frame, the two form a locking structure to lock the vertical frame component and the vertical frame component. The second hook component 402 can have a bent portion 4021, and the first hook component 401 is provided with an opening 4011 of a size that allows the end of the bent portion 4021 to pass through, and the second hook component 402 can be matched to enter the first hook component from above so that the end of the bent portion 4021 enters the opening 4011 to form a locking structure.

[0080] The structure of the first hook component 401 of one unit plate and the second hook component 402' of another unit plate can be as follows: Figure 5 , 6 7. The second hook component 402' has a bent portion 4021', and the first hook component 401 is provided with an opening 4011 of a size that allows the end of the bent portion 4021' to pass through. The second hook component 402' can fit into the first hook component from above so that the end of the bent portion 4021' enters the opening 4011 to form a locking structure. In this way, the auxiliary frame component can be locked with the vertical frame component.

[0081] Corresponding to such a locking structure, when two unit panels are assembled, the first unit panel 100 can be first fixed at an edge position of a predetermined height, for example, Figure 3 As shown, the second unit panel 100' is fixed at the leftmost position, and then the vertical frame assembly of the second unit panel 100' is aligned with the auxiliary frame component of the first unit panel 100 and the second unit panel 100' is lowered so that the bent portion 4021' of the hook component 402' of the vertical frame component 20' of the second unit panel 100' matches the opening 4011 of the first hook component 401 entering the auxiliary frame component 10 of the first unit panel 100, thereby achieving the cooperation between the first unit panel 100 and the second unit panel 100'.

[0082] In an embodiment not shown in the drawings of the present application, the rear end face of the auxiliary frame member 10 perpendicular to the transverse side surface can be used as the auxiliary frame connection surface 101 and a first locking device can be provided thereon, and the rear end face of the vertical frame member 20 perpendicular to the transverse side surface of the auxiliary frame receiving portion can be used as the vertical frame connection surface 201 and a second locking device can be provided thereon. The above-mentioned first hook member and second hook member can be used as the first locking device and the second locking device. In this configuration, only when two unit panels are combined, the combination needs to align the two rear end faces to form a locking structure.

[0083] It should be understood that the hook components on the auxiliary frame member 10 and the vertical frame member 20 in the above embodiment can be interchanged without hindering the implementation of the present invention. For example, the auxiliary frame member 10 can be provided with a hook component 402 having a bent portion 4021, while the vertical frame member 20 can be provided with a hook component 401 having an opening 4011. Therefore, the first locking device and the second locking device in the present application are not intended to be limited to a specific configuration form, as long as the invention purpose of forming a locking structure can be achieved, it is within the protection scope of the present application.

[0084] In embodiments not shown in the drawings of the present application, other structures may be used as the first locking device and the second locking device. For example, the first locking device may be configured as a longitudinal notch on the attachment frame connection surface, that is, a notch extending along the combination direction of the two unit panels. The second locking device may be configured as a hook provided on the vertical frame connection surface that can fit into the longitudinal notch. When combining two unit panels, the vertical frame component of the first unit panel may be dropped along the attachment frame component of the second unit panel so that its hook fits into the longitudinal notch to achieve the matching of the attachment frame component and the vertical frame component.

[0085] The arrangement positions of the auxiliary frame member 10 and the vertical frame member 20 of the unit panel in the present application are not necessarily the positions shown in FIG. 1 , but can also be as follows: Figure 2 Compared to Figure 1 The structure in Figure 2 In the embodiment, the vertical frame assembly and the auxiliary frame component are interchanged in position, but have the same structure.

[0086] exist Fig. 9 , 10 In the illustrated embodiment, the frame member 10 further includes a panel mounting portion 102, the inner shape and size of the panel mounting portion matches the panel to be mounted, and the outer side is provided with a front sealing member connecting structure 1021 for attaching a sealing member 501, and the sealing member 501 extends laterally from the outer side surface of the panel mounting portion 102. The sealing member 501 may be Figure 1 , 2 The cantilever beam-shaped elastic sealing component shown, such as a rubber sheet, may also be other sealing strip structures, such as a D-shaped sealing strip.

[0087] In order to enhance the sealing effect, an intermediate sealing component connecting structure 1022 may be included at a position on the rear side of the panel mounting portion 102 relative to the sealing component connecting structure 1021. The intermediate sealing component connecting structure 1022 may be formed by extending laterally from the outer side surface of the panel mounting portion, and its rear surface may be an installation surface for installing a sealing component, for example, it may be a card groove structure for installing an intermediate sealing component, such as a D-shaped sealing strip 502, and the D-shaped sealing strip 502 may be deformable in the front-to-back direction.

[0088] In order to further enhance the sealing effect, a rear side sealing component connection structure 1023 may be provided on the rear side end face 103 of the auxiliary frame component 10. The rear side sealing component connection structure 1023 may be a card slot facing the rear side for installing a rear side sealing component, such as a D-shaped sealing strip 503. The D-shaped sealing strip 503 may be deformable in the front-to-back direction.

[0089] In order to match the above structure of the auxiliary frame member 10, a panel mounting portion 202 is provided on the vertical frame member 20. The inner shape and size of the panel mounting portion 202 match the panel to be installed, and a front sealing member connecting structure 2021 is provided on the outer side to attach a sealing member 501A. The sealing member 501A extends laterally from the outer surface of the panel mounting portion 202. The sealing members 501, 501A can be Figure 1 , 2 The cantilever beam elastic sealing member shown, such as a rubber sheet, can also be other sealing strip structures, such as a D-shaped sealing strip. The shape and size of the sealing member 501 and the sealing member 501A are configured so that after the auxiliary frame member and the vertical frame member are matched, the two are at least partially staggered to form a first longitudinal sealing structure.

[0090] It should be understood that the first longitudinal sealing structure does not necessarily have to use sealing components that are arranged opposite to each other. For example, the sealing component can be provided only on the auxiliary frame component or only on the vertical frame component, and the other side can achieve sealing by deforming the sealing component only through the side wall. In addition, not all sealing components are elastic sealing components. For example, an elastic sealing component can be provided on one side, and a rigid sealing component, such as a laterally extending portion of the side wall, can be provided on the other side.

[0091] In order to match the intermediate sealing component connection structure 1022 to enhance the sealing effect, the panel mounting portion 202 includes an intermediate sealing component connection structure 2022 at a position on the rear side relative to the sealing component connection structure 1021, i.e., a position adjacent to the receiving portion of the auxiliary frame component. The intermediate sealing component connection structure 2022 can be formed by extending laterally from the outer side surface of the panel mounting portion, and can be configured to have a front plane. The shape and size are configured such that after the auxiliary frame component and the vertical frame component are matched, the front plane of the intermediate sealing component connection structure 2022 forces the intermediate sealing component, such as the D-shaped sealing strip 502, to deform in the front-to-back direction to form a second longitudinal sealing structure. Furthermore, an installation structure can be provided on the front plane for installing a sealing component, such as a slot structure, for installing an intermediate sealing component, such as a D-shaped sealing strip, and the D-shaped sealing strip can be deformed in the front-to-back direction. The shape and size of the intermediate sealing component are configured so that after the auxiliary frame component and the vertical frame component are matched, at least one of the intermediate sealing component on the intermediate sealing component connecting structure 2022 and the intermediate sealing component 502 is deformed in the front-to-back direction to form a second longitudinal sealing structure.

[0092] In order to match the rear sealing component connection structure 1023 to further increase the sealing effect, the end surface 232 of the rear area of ​​the vertical frame component 20 can be configured so that after the auxiliary frame component and the vertical frame component are matched, the rear end surface forces the rear sealing component, such as the D-shaped sealing strip 503, to deform in the front-to-back direction to form a third longitudinal sealing structure. Further, a rear sealing component connection structure can be provided, such as a card groove facing the front side, for installing the rear sealing component, such as the D-shaped sealing strip, which can be deformed in the front-to-back direction, and its shape and size can be configured so that after the auxiliary frame component and the vertical frame component are matched, at least one of the rear sealing component on the rear sealing component connection structure and the rear sealing component 503 is deformed in the front-to-back direction to form a third longitudinal sealing structure.

[0093] In the above-mentioned embodiments of the sealing structure, especially in some embodiments of the sealing structure formed by only a single sealing member, it is also possible to set the sealing strip installation structure on the opposite component. For example, in the embodiment of the second longitudinal sealing structure, the sealing strip 502 installation structure can be set on the mounting part of the attached frame component of the vertical frame component, and the attached frame component 10 is provided with a transversely extending part and the rear side of the part is used to squeeze the sealing strip 502 to deform it to form the second longitudinal sealing structure. For another example, in the embodiment of the third longitudinal sealing structure, the sealing strip 503 installation structure can be set on the mounting part of the attached frame component of the vertical frame component, and the rear side of the attached frame component 10 is used to squeeze the sealing strip 503 to deform it to form the third longitudinal sealing structure.

[0094] The present invention innovatively adopts two unit panels adjacent to each other on the left and right to share the same vertical frame component to bear the wind load of the adjacent unit panels on the left and right, avoiding the split design of the column profile using two vertical frames, and the crossbeam does not need to be flush with the vertical frame on the indoor side, saving material usage, thereby improving the economy of the unit curtain wall. The two unit panels adjacent to each other on the left and right are hung together by a locking structure formed by a hook component or a structure with a similar principle, and the joints between the unit panels are sealed with a sealing strip to form a closed curtain wall. At the same time, the joints between the unit panels can also be sealed with a sealing component such as a sealant to form a closed curtain wall.

[0095] A plurality of unit panels 100 provided in the embodiments of the present application can be conveniently assembled into a unit curtain wall, which may include one or more layers. Fig.11 , 12 In the embodiment of the single-layer unitized curtain wall shown in the figure, the first unit panel 100 is first fixed at the required installation height and installation position, for example Fig.11The leftmost position in the vertical direction is fixed to the wall to be shielded by a part of the outer frame assembly, for example, by fasteners, and then the auxiliary frame component 10' of the second unit panel 100' is aligned with the vertical frame component 10 and dropped with the vertical frame component 10 as a reference, so that the second locking device 402 on the vertical frame component 10 and the first locking device 401' on the auxiliary frame component 20' form a locking structure. For example, after the locking structure, the first unit panel 100 and the second unit panel can be locked. In this way, other unit panels can be installed sequentially to complete the installation of the row of curtain walls. If a higher curtain wall needs to be formed, unit panels of other heights can be fixed in this way to form a higher curtain wall.

[0096] Each layer of the unitized curtain wall in the present application includes at least two unit panels, such as the unit panels 100 and 100'. The two are laterally spliced ​​together and locked to each other through the locking structure provided on the unit panels, or locked to each other through an additional locking structure. After the two are locked, the waterproof effect is achieved through the first, second, and third longitudinal sealing structures. However, there will always be some water, such as water that enters the curtain wall in the form of mist and condenses to form water, and enters the interior of the curtain wall. Therefore, a drainage structure can be further provided to discharge the water that enters the inner side, i.e., the rear side, of the curtain wall to the outside of the unitized curtain wall.

[0097] exist Figures 1 to 4 In the embodiments shown in 1A to 1D, the unitized curtain wall can provide a water-repellent plate 601 for every two unit panels of each layer, and the water-repellent plate 601 is transversely attached to the front cavity portion 3122 of the upper cross beam member 31 of the two unit panels 100 and 100'. Figure 1D As shown, the cross section of the water-repellent plate 601 can be configured to conform to the shape of the front cavity portion 3122, for example, roughly L-shaped. Figures 1 to 4 As shown, the water-repellent plate 601 is configured to cover the transverse gap between the two unit panels 100, 100' laterally, and extends to the outside of the first longitudinal sealing structure in the front-to-back direction. In this way, water that passes through the first longitudinal sealing structure of the previous layer and enters the unit curtain wall can fall on the water-repellent plate 601 of the next layer, and then be guided by the water-repellent plate 601 to the outside of the panel 2 of the unit curtain wall, thereby forming a first drainage channel, and the path of water outflow is shown by the arrow trajectory in the figure. The water-repellent plate 601 can be designed in a funnel shape, that is, it is tilted downward from both sides to the middle laterally, so that water can be concentrated from the middle of the water-repellent plate, and then discharged from the gap between the two unit panels outside the first longitudinal sealing structure. It can also be designed as a convex design, so that water is discharged from both sides. The water-repellent plate can also be designed as a plane.

[0098] A front drainage hole 3125 may be provided on the front side wall 3123 of the upper cross beam component 31 of the unitized curtain wall for draining water from the rear cavity portion 3121 of the upper cross beam component to the front cavity portion 3122. As an improvement, the unitized curtain wall may also provide a drainage plug 602 for each two unit panels of each layer, the drainage plug 602 being connected to the upper cross beam rear cavity portion 3121 of the upper cross beam component 31 of the first unit panel 100 and the second unit panel 100' and extending to the rear cavity portion 3121 of the upper cross beam of the first unit panel and the rear cavity portion 3121' of the upper cross beam of the second unit panel respectively without exceeding the position of the front drainage holes 3125, 3125'. The drainage plug 602 is connected with the front drainage holes 3125, 3125' to form a second drainage channel, as shown by the track of the arrows in the figure. The drainage insert 602 may be configured to conform to the cross-sectional shape of the rear cavity portion 3121 of the upper beam, and may be attached to the rear cavity portion of the upper beam, for example, by a bayonet structure.

[0099] The drainage plug 602 is configured to cover the gap between the two unit plates at the upper crossbeam position after being fitted, and the portion of its inner surface close to the front side is lower than the portion close to the rear side to form a slope. In some embodiments, the drainage plug can be configured such that its inner surface gradually decreases from the middle to both sides in the transverse direction to form a slope to facilitate water to flow to the front drainage holes 3125, 3125' on both sides.

[0100] This form of collecting water in the front area of ​​the vertical frame through the drainage plug of the upper horizontal frame and then flowing out of the panel from the bottom joint of the unit plate of the current layer in an organized manner is called same-layer drainage in this application. The drainage process of the vertical frame is all carried out in the front area of ​​the vertical frame, and the rear area of ​​the vertical frame does not participate in the drainage. The rear area of ​​the vertical frame can be used as needed, for example, by setting plugs to connect the upper and lower unit plates, so as to facilitate load transfer.

[0101] exist Figures 5A to 5EIn the embodiment of the unitized curtain wall shown in 5 to 8, it includes at least a first unit panel 100 and a second unit panel 100 fixed together laterally. Similar to the previous embodiment, each of the first unit panel and the second unit panel has the following structure: including an outer frame assembly 1 and a panel 2 connected to the outer frame assembly, the outer frame assembly 1 includes a first side frame component 10, such as an auxiliary frame component, a second side frame component 20, such as a vertical frame component, and an upper beam component 31 and a lower beam component 32 connected to the first side frame component and the second side frame component; wherein the vertical frame component of the first unit panel and the auxiliary frame component of the second unit panel are fixed by a locking structure to achieve the lateral fixation. The upper beam component 31 includes an upper portion 311 and a lower portion 312, the upper portion 31 has an upper beam front cavity portion 3122, an upper beam rear cavity portion 3121 separated from the upper beam front cavity portion by an upper beam front side wall 3123, and a water flow cavity 313 between the front cavity and the lower portion 312. In this embodiment, the water passage chamber 313 is laterally connected with the rear cavity portion 3121 through a front drainage hole 3131 (3131' for another unit plate spliced ​​laterally) arranged on the front side wall 3123 of the upper cross beam, and is connected with the first side frame member 10, such as the auxiliary frame member 10, through a bottom drainage hole 3132 (3132' for another unit plate spliced ​​laterally), so that water entering the rear cavity portion can enter the water passage chamber 313 along the bottom surface of the rear cavity portion through the front drainage hole 3131 and then be discharged into the guide cavity 104 that runs through the auxiliary frame member 10 from top to bottom through the bottom drainage hole 3132. The through-going guide cavity 104 can be positioned close to the front of the attached frame member, and its front and rear positions correspond to the positions of the water-dispensing plate 601, that is, its vertical projection falls on the plane of the water-dispensing plate 601, so that water entering the guide cavity 104 can be longitudinally guided by the guide cavity and fall onto the water-dispensing plate 601 of the next layer, and then be discharged, and the above channel forms a second drainage channel.

[0102] In some embodiments, a second side frame member 20 of the unit panel, such as the front area 21 of the vertical frame member 20, can be provided with a guide cavity 204 with the same function, which is connected to its corresponding bottom surface drainage hole to achieve the same drainage function.

[0103] The upper beam rear cavity is a structure with an open top formed by the upper beam front side wall, the upper beam rear side wall and the upper beam bottom plate connected to each other. The upper beam front cavity is composed of the upper beam front side wall and a water guide extending forward at an angle to the upper beam front side wall.

[0104] In this embodiment, the vertical frame member 20 may also have a front portion 21 and a rear portion 22, wherein the front portion 21 and the rear portion 22 are fixedly connected or integrally formed, wherein the front portion 21 and the rear portion 22 define a frame member receiving portion 23, and the frame member receiving portion 23 is used to cooperate with the frame member 10 of another unit plate when two unit plates are combined, so it can be configured to be basically consistent with the shape of the frame member 10 to completely receive the frame member 10. For example, Figure 1 As shown, the auxiliary frame member receiving portion 23 may include a transverse outward wall 231 and a forward wall 232 of the vertical frame member.

[0105] The rear area 22 can have a rectangular closed cross-sectional structure as shown in the figure, so that even if water breaks through the first and second longitudinal sealing structures, the water will not flow into the rear area 22 and thus flow downward along the rear area, thus avoiding the need for the upper cross beam component and the lower cross beam component of the outer frame assembly to completely wrap the entire front and rear dimensions of the vertical frame in the front and rear directions in order to achieve drainage. At the same time, since the wind load is borne by the side frame part, that is, the vertical frame component and the auxiliary frame component, reducing the size of the upper cross beam component and the lower cross beam component can greatly save the material of the upper cross beam and the lower cross beam while ensuring the resistance to wind load. In some embodiments not shown, the rear area does not need to have a closed cross-sectional structure and can still prevent water from entering the interior of the rear area 22, as long as it is ensured that the wall 232 at the receiving portion 23 of the auxiliary frame component has a closed structure, that is, a closed structure in the front and rear directions is formed between the front area and the rear area and reaches or exceeds the rear cavity portion 3121 of the upper cross beam component in the front and rear directions. For example, the rear area 22 has a concave cross-sectional structure that is open backwards. The cross-sectional shape of the rear portion is not necessarily rectangular or based on a rectangle, and may also be other forms such as polygonal, circular, etc. The closed structure may be a part of the rear portion 22, or a separate part between the rear portion and the front portion.

[0106] In this embodiment, the water entering the front area of ​​the vertical frame is collected by the drainage plug core of the upper horizontal frame, and then flows out of the panel in an organized manner from the bottom joint of the next layer of unit panels. In this method, the water flowing into the rear cavity of the upper horizontal frame flows into the profile cavity of the front cavity of the upper horizontal frame through the drainage holes of the upper horizontal frame, and then flows into the auxiliary frame and vertical frame cavity of the next layer of unit panels through the drainage holes. Under the action of gravity, the water falls on the water-blocking board and then flows out of the panel.

[0107] The present invention provides a drainage structure in the front area of ​​a unitized curtain wall vertical frame, which solves the technical problem that the entire vertical frame cavity is involved in sealing, waterproofing and drainage, resulting in a large amount of horizontal frame material consumption, and has the following advantages:

[0108] First, the overall cost is low: the cross-section of the horizontal frame does not need to be basically flush with the vertical frame on the indoor side, so organized drainage can be achieved, saving material usage, thereby improving the economy of the unitized curtain wall.

[0109] Secondly, to achieve organized drainage: when water seeps into the joints of the curtain wall, the water can be discharged to the outside of the panel in an orderly manner according to the designed structure and drainage path. Waterproofing and drainage are carried out in the front area of ​​the vertical frame, and the rear area of ​​the vertical frame does not participate in drainage.

[0110] Finally, it is convenient for load transfer: the front area of ​​the vertical frame is used for drainage, and the rear area of ​​the vertical frame can be used to connect the vertical frames of the upper and lower unit plates, simplifying the load transfer path.

[0111] It should be understood that the side frame components of the outer frame assembly of the unit panel of the present application are not limited to the form of the auxiliary frame component 10 and the vertical frame component 20 shown in the drawings, and can also be, for example, the same structure of the side frame components, as long as the first drainage channel and the second drainage channel can be formed, they belong to the protection scope of the present invention. For example, the outer frame assembly can have the same upper crossbeam component and lower crossbeam component, but the side frame components do not have complementary structures but have the same structure, and can still be provided with a front area close to the panel and a rear area away from the panel, and a first longitudinal sealing structure and a second longitudinal sealing structure are formed in the front area, and a first drainage channel is formed between the first longitudinal sealing structure and the second longitudinal sealing structure, and the front area has a cavity that passes through from top to bottom and can be connected to the water passage cavity of the upper crossbeam to form a second drainage channel.

[0113] Furthermore, while advantages associated with certain embodiments of the technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the technology.
