Description

Technical Field

[0001] This invention belongs to the field of exterior wall curtain wall technology, specifically a waterproof structure for the top of a combined aluminum plate and glass curtain wall. Background Technology

[0002] With the development of building curtain wall technology, aluminum panel and glass composite curtain walls have been widely used in modern high-rise buildings due to their excellent decorative effect and functional characteristics. As a key part where the curtain wall system meets the roof parapet wall, the waterproof structural design of the top node of the curtain wall directly affects the air tightness and water tightness of the entire curtain wall system.

[0003] In existing technologies, the waterproofing structure at the top of curtain walls typically employs a combination of multi-layer sealant caulking and a capping plate. However, this traditional structure has the following drawbacks: First, long-term exposure to the outdoor environment can cause the sealant to age and crack, leading to leakage; second, if the aluminum or glass panels at the top of the curtain wall are damaged, the complex connection of the top nodes often necessitates large-scale dismantling for replacement, resulting in high maintenance difficulty and cost.

[0004] Therefore, there is an urgent need for a curtain wall top connection structure that can both guarantee reliable anti-seepage performance and facilitate independent replacement of panels later. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0006] A waterproof structure for the top of an aluminum panel and glass composite curtain wall includes:

[0007] The exterior curtain wall is fixed to the exterior wall of the building by a keel structure. The top of the exterior curtain wall is provided with an upper protrusion strip, and a restraint groove is provided on the side of the upper protrusion strip facing the keel structure.

[0008] The V-shaped curtain wall has elastic support members that are slidably installed on the inner side of the V-shaped curtain wall. The elastic support members can move closer to or away from the keel structure along the inner wall of the V-shaped curtain wall. The elastic support members are slidably installed on the keel structure. The bottom of the V-shaped curtain wall is provided with a groove for fitting the upper convex strip and an elastic constraint member for fitting the constraint groove. The top of the V-shaped curtain wall is provided with a folding part.

[0009] The sealing component is fixedly installed on the inside of the parapet wall and can be detachably installed with the reverse fold.

[0010] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, a supporting frame and a moving guide rail are installed on the inner side of the V-shaped curtain wall. Both ends of the moving guide rail are equipped with sealing strips, and elastic support components are movably installed inside the moving guide rail.

[0011] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the elastic support includes a movable seat, which is slidably fitted in a movable guide rail. A fixed sleeve is fixedly installed on the movable seat, and a movable rod is connected to the fixed sleeve by a spring. The free end of the movable rod extends to the outside of the fixed sleeve and is connected to a rolling element.

[0012] A support box is installed on the keel structure. The upper and lower sides of the support box are open, and a support groove is provided on the top. The support groove is compatible with the rolling element.

[0013] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the sealing component includes an installation plate fixed to the top of the inner side of the parapet wall and a sealing plate movably disposed relative to the installation plate. The sealing plate is provided with a T-shaped hole, and a guide column passes through the T-shaped hole. One end of the guide column is provided with a large head, and the other end passes through the T-shaped hole and is threadedly connected to the installation plate. A spring component is fitted on the outside of the guide column. The spring component is located between the sealing plate and the installation plate, and a sealing structure is provided between the installation plate and the reverse fold.

[0014] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the sealing structure includes a flexible sealing plate integrally installed on the mounting plate and a sealing strip installed at the bottom of the reverse fold, with the sealing strip and the flexible sealing plate working together.

[0015] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the flexible sealing sheet includes an integrally connected elastic bending part and a hook part, and the sealing strip has an indentation on the side facing away from the sealing plate, with the hook part and the indentation part being compatible.

[0016] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the bottom side of the V-shaped curtain wall located outside the upper convex strip is attached to the outer curtain wall, and a gap is reserved between the other side and the outer curtain wall.

[0017] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, the bottom of the V-shaped curtain wall is provided with a downwardly sloping movable groove on the side facing the keel structure. The movable groove has an angle of 45° with the horizontal plane. The elastic constraint member includes a movable block. One end of the movable block passes through the movable groove and is connected to a stop block. The bottom of the movable block is provided with a slope surface and a hook head body for forming a hook structure with the constraint groove on the side facing the upward convex strip.

[0018] In the aforementioned interlayer extra-long aluminum plate and glass combined curtain wall sealing structure, a spring body is installed in the movable groove, and a sealing plate is installed at the opening of the movable groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention achieves vertical installation of the V-shaped curtain wall by providing an upper protruding strip with a constraint groove on the outer curtain wall, and an elastic constraint member on the V-shaped curtain wall that matches the constraint groove, in conjunction with a support box and an elastic support member (which can move linearly in a moving guide rail). When the V-shaped curtain wall needs to be replaced separately, the reverse fold of the V-shaped curtain wall can be moved downward while deflecting around the upper protruding strip at a certain angle, causing the upper protruding strip to press the movable block into the movable groove to compress the spring body. This causes the hook body and the constraint groove, which originally formed a hook structure, to become separated, thus enabling the V-shaped curtain wall to be vertically separated from the sealing member and the outer curtain wall.

[0021] 2. This invention achieves sealing by setting a flexible sealing piece on the mounting plate and adapting the flexible sealing piece and the sealing strip. After the V-shaped curtain wall is installed, the elastic deformation capability of the flexible sealing piece's elastic bending part can be used to facilitate the separation of the hook part and the concave part when the V-shaped curtain wall is dismantled.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Please see Figures 1 to 7 This embodiment provides a waterproof structure for the top of an aluminum plate and glass combined curtain wall. The structure mainly includes an outer curtain wall 10, a V-shaped curtain wall 20, and a sealing component 30.

[0033] The exterior curtain wall 10 is fixedly installed on the exterior wall of the building by means of the keel structure 22. The top of the exterior curtain wall 10 is provided with an upward protruding upper ridge 11, and the upper ridge 11 has an inwardly recessed constraint groove 12 on the side (i.e., the inner side) facing the keel structure 22.

[0034] V-shaped curtain wall 20: An elastic support member 21 is slidably installed on the inner side of the V-shaped curtain wall 20 (i.e. the side facing the keel structure 22), and the elastic support member 21 is restricted to only approaching or moving away from the keel structure 22 along the inner wall of the V-shaped curtain wall 20. The elastic support member 21 itself is slidably installed on the keel structure 22, thereby providing the main support for the V-shaped curtain wall 20.

[0035] Specifically, a support frame 201 and a moving guide rail 202 are fixedly installed on the inner side of the V-shaped curtain wall 20. After the V-shaped curtain wall 20 is installed, its moving guide rail 202 is horizontally set, and both ends are equipped with seals 203 to prevent the moving seat 211 from falling out. The elastic support member 21 includes a moving seat 211, a fixed sleeve 212, a movable rod 213, and a rolling element 214. The moving seat 211 is slidably fitted in the moving guide rail 202. The fixed sleeve 212 is fixedly installed on the moving seat 211. The movable rod 213 is connected to the fixed sleeve 212 by a spring. The free end of the movable rod 213 extends to the outside of the fixed sleeve 212 and is connected to the rolling element 214. Correspondingly, a support box 221 is fixedly installed on the keel structure 22. The upper and lower sides of the support box 221 are open, and a support groove 222 is provided on its top. The width of the support groove 222 is smaller than the internal space width of the support box 221, which can provide space for subsequent dismantling of the V-shaped curtain wall 20. The support groove 222 is adapted to the rolling element 214. During installation, the rolling element 214 falls into the support groove 222 and maintains elastic contact under the action of the spring, which not only achieves vertical support, but also allows the rolling element 214 to be disengaged from the support groove 222 by pressing down during dismantling.

[0036] The bottom of the V-shaped curtain wall 20 is provided with a groove for fitting the upper protrusion 11. The top of the inner side of the groove is provided with an inclined surface for the upper protrusion 11 to rotate, and an elastic constraint member 23 for fitting the constraint groove 12. One side of the bottom of the V-shaped curtain wall 20, located outside the upper protrusion 11, is tightly attached to the surface of the outer curtain wall 10. A sealing gasket can be used on this contact surface to ensure a sealed installation. The other side has a gap (8-12mm) reserved between it and the outer curtain wall 10. This gap can provide space for the V-shaped curtain wall 20 when it needs to be removed.

[0037] Furthermore, the bottom of the V-shaped curtain wall 20, facing the keel structure 22, has a downwardly angled movable groove 204, preferably at an angle of 45° to the horizontal plane. A spring body 205 is installed inside the movable groove 204, and a sealing plate 206 is installed at the opening of the movable groove 204. The elastic constraint member 23 includes a movable block 231, one end of which passes through the movable groove 204 and is connected to a stop block 232. The bottom of the movable block 231, facing the upper protrusion 11, has a sloping surface (to facilitate the entry of the upper protrusion 11) and a hook head body 233 for forming a hook structure with the constraint groove 12. Under the action of the spring body 205, the hook head body 233 is normally embedded in the constraint groove 12, thereby locking the bottom of the V-shaped curtain wall 20 with the upper protrusion 11. When disassembly is required, pressure is applied to the top of the folded part 24 and it will deflect at a certain angle and tilt. The upper protrusion 12 will squeeze the movable block 231 to move towards the movable groove 204, compress the spring body 205, thereby causing the hook body 233 to disengage from the constraint groove 12 and release the lock. Then, it will move upward to complete the separation of the V-shaped curtain wall 20 from the outer curtain wall 10.

[0038] The top of the V-shaped curtain wall 20 is equipped with a reverse fold 24, which bends toward the parapet wall side for connection with the top sealing member 30.

[0039] Sealing component 30: The sealing component 30 is fixedly installed on the inner top of the parapet wall and forms a detachable sealed connection with the folded portion 24 at the top of the V-shaped curtain wall 20. Specifically, the sealing component 30 includes a mounting plate 31 and a sealing plate 32. The mounting plate 31 is fixed to the inner top of the parapet wall by expansion bolts or other fasteners. The sealing plate 32 is movably disposed relative to the mounting plate 31. A T-shaped hole is provided on the sealing plate 32, and a guide post 33 passes through the T-shaped hole. One end of the guide post 33 has a large head, and the other end passes through the T-shaped hole and is threadedly connected to the mounting plate 31. A spring component 34 is fitted on the outer side of the guide post 33. The spring component 34 is located between the sealing plate 32 and the mounting plate 31 and provides a pre-tightening force to the sealing plate 32 toward one side of the V-shaped curtain wall 20.

[0040] A sealing structure is provided between the mounting plate 31 and the folded portion 24. This sealing structure includes a flexible sealing piece 35 integrally formed on the mounting plate 31 and a sealing strip 241 installed at the bottom of the folded portion 24. The flexible sealing piece 35 is made of elastic material such as rubber or silicone and includes an integrally connected elastic bending portion 351 and a hook portion 352. The sealing strip 241 has a recessed portion 242 on the side facing away from the sealing plate 32. When the V-shaped curtain wall 20 is installed in place, the sealing plate 32 is pressed against the inner side of the folded portion 24 by the spring member 34. At the same time, the hook portion 352 elastically deforms and gets into the recessed portion 242, forming a reliable labyrinth seal. The top surface of the free end of the hook portion 352 is tightly fitted to the folded portion 24 to prevent rainwater from seeping in from the top. When the V-shaped curtain wall 20 needs to be disassembled, as the reverse folding part 24 moves downward, it will also move inward relative to the hook part 352, causing the hook part 352 to disengage from the recessed part 242, thus achieving rapid separation.

[0041] The installation and disassembly process of this structure is briefly described below:

[0042] During installation: First, install the outer curtain wall 10, the keel structure 22, and the sealing components 30. Then, lower the V-shaped curtain wall 20 from top to bottom towards the installation position, aligning the bottom groove with the upper protrusion 11, while simultaneously aligning the rolling element 214 with the support groove 222. Lower the V-shaped curtain wall 20 vertically, so that the inclined surface of the hook body 233 of the elastic constraint component 23 contacts the top of the upper protrusion 11. The upper protrusion 11 presses against the inclined surface, forcing the movable block 231 to overcome the elastic force of the spring body 205 and retract into the movable groove 204. When the V-shaped curtain wall 20 reaches its lowest point, the hook body 233 faces the constraint groove 12 and automatically pops out and hooks into the constraint groove 12 under the restoring force of the spring body 205. At the same time, the rolling element 214 of the elastic support component 21 falls into the support groove 222 of the support box 221, completing the bottom locking. At the same time, the folded part 24 moves downward and squeezes the sealing member 30. Under the guidance of the guide post 33 and the spring member 34, the sealing plate 32 automatically presses the folded part 24. At the same time, the hook part 352 of the flexible sealing piece 35 is inserted into the concave part 242 of the sealing strip 241, completing the bottom sealing of the folded part 24.

[0043] During disassembly and replacement: Attach the suction cup tool to the top of the folded part 24, lower it while bringing the folded part 24 close to the parapet wall, and continue to compress the sealing plate 32. This causes the sealing strip 241 to further bend the elastic bending part 351. As the top surface of the free end of the hook part 352 is tightly attached to the folded part 24, the hook part 352 is dislodged from the recessed part 242. At the same time, the upper protruding strip 11 will press the movable block 231 into the movable groove 204 and move away from the constraint groove 12 until the hook body 233 and the constraint groove 12 separate, releasing the fixing relationship. The movable seat 211 moves away from the parapet wall within the movable guide rail 202. Finally, the V-shaped curtain wall 20 is vertically removed, and a new V-shaped curtain wall 20 is reinstalled.

[0044] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
