Description

Technical Field

[0001] This utility model belongs to the field of curtain wall technology for building exterior walls, and in particular, it is a hollow-slot waterproof aluminum panel curtain wall. Background Technology

[0002] In the field of building curtain walls, the traditional method of waterproofing aluminum panel curtain walls is to inject silicone sealant into the joints of the aluminum panels. This is a traditional and reliable method. However, due to the difference in material between the sealant and the aluminum panel, it is difficult for the color and texture of the sealant joint to completely match the decorative aluminum panel, thus affecting the architectural effect. In recent years, open-joint aluminum panel curtain walls have been increasingly widely used by architects because they do not have the influence of sealant joints. However, how to reliably and durablely waterproof open-joint aluminum panel curtain walls remains a challenge. In practical applications, many projects using open-joint aluminum panel curtain walls have experienced varying degrees of leakage, affecting the functionality of the building.

[0003] A composite curtain wall using aluminum panels and stone cladding, disclosed in publication number CN220889099U, employs two mounting boxes, each fixed to both sides of the front of a mounting plate. During installation, the curtain wall is fitted onto the mounting box surface, and a hand crank is turned. The hand crank, via a rotating rod, drives a cam, which in turn moves a movable plate on each side. The movable plate then moves a fixed plate, securing the curtain wall in its mounting groove. The inclusion of protective components enhances building safety and comfort, effectively preventing adverse effects from external factors. However, it lacks improvements in waterproofing. Therefore, a novel curtain wall structure with superior waterproofing, aesthetic appeal, and high application value is designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a gap-sealed waterproof aluminum panel curtain wall to solve the problem of curtain wall leakage.

[0005] To achieve the above objectives, the main structure of this utility model's open-joint waterproof aluminum panel curtain wall is as follows: The open-joint waterproof aluminum panel curtain wall consists of a frame system, a waterproof system, and a decorative panel system. These three systems are installed on-site in a counter-clockwise order from bottom to top: first, the frame system is installed; then, the concealed acceptance is passed; next, the waterproof system is installed; then, a water spray test is passed; and finally, the decorative panel system is installed to form the final curtain wall of this patented product. The frame system consists of steel square tube columns, steel square tube beams, steel angle brackets, and bolts and fasteners; the waterproof system consists of waterproof aluminum panels, rubber gaskets, silicone weather-resistant sealant, and screws and fasteners; the decorative panel system consists of aluminum column heads, decorative aluminum panel panels, a first aluminum panel subframe, EPDM adhesive strips, silicone weather-resistant sealant, bolts and fasteners, and screws and fasteners. The positional relationship between the systems is as follows: from the outside in, the first layer is the decorative panel system, the second layer is the waterproof system, and the third layer is the frame system. The decorative panel system is attached to aluminum column heads fixed to the outer surface of the frame system via a first aluminum plate subframe installed at the folded edge of the aluminum panel. To prevent collision and friction noise between the first aluminum plate subframe and the aluminum column heads, a continuous EPDM adhesive strip is installed in the groove of each first aluminum plate subframe. The waterproof system temporarily fixes the waterproof aluminum panel to the outer surface of the frame system with screws and fasteners, and then presses the waterproof aluminum panel onto the outer surface of the frame system through the aluminum column heads, ensuring a tight bond. All screw heads are coated with silicone weather-resistant sealant for waterproofing. To prevent bimetallic chemical corrosion between the waterproof aluminum panel and the steel frame system, a rubber pad is placed between the contact surfaces. The frame system is connected to the main building structural beams via connecting supports, forming the final product of this patent: a slotted waterproof aluminum panel curtain wall. The waterproofing system is characterized by: waterproof aluminum panels that are directly and continuously flatly attached to the outer surface of the frame system; the joints between adjacent waterproof aluminum panels are all located on the centerline of the steel square tube columns and beams; and silicone weather-resistant sealant is injected at the joints to form a continuous and independent waterproof surface, making the waterproofing measures simple and reliable. The decorative panel system is characterized by: decorative aluminum panels that are attached to the aluminum column heads using a first aluminum panel subframe, instead of being directly screwed to the frame system as in the past. Engineering experience has shown that the reason why gapped aluminum panel curtain walls generally leak severely is that rainwater extends into the frame system through these connecting screws, and then seeps into the interior, seriously affecting the functionality of the curtain wall.

[0006] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0007] There is no direct connection between the decorative aluminum panel and the frame system. Instead of using screws to directly attach it to the frame system as is the common practice, the risk of rainwater seeping into the room through the screw gaps is completely eliminated.

[0008] The decorative aluminum panel is attached to the aluminum column head by the first aluminum panel frame, instead of being directly screwed to the frame system by screws as is common in the past. This directly avoids the risk of rainwater seeping into the room through the screw gaps, thereby improving the application value and promotion prospects of this patented open-gap waterproof aluminum panel curtain wall.

[0009] This open-gap waterproof aluminum panel curtain wall has a good architectural effect and a reliable and durable waterproof system. It can easily achieve reliable waterproofing of the open-gap curtain wall and prevent rainwater from seeping into the interior and affecting the building's functionality. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0032] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0033] Existing open-gap aluminum panel curtain walls mostly suffer from varying degrees of water leakage during use, affecting the use of building functions. In order to ensure the normal use of building functions, an open-gap waterproof aluminum panel curtain wall with waterproof function is designed, and the specific structure is as follows.

[0034] The main components of the open-joint waterproof aluminum panel curtain wall are:

[0035] Frame system: steel square tube columns A1, steel square tube beams A2, steel angle brackets A3, bolt fasteners A4;

[0036] Waterproofing system: Waterproof aluminum panel B1, rubber gasket B2, silicone weather-resistant sealant B3, screws and fasteners B4;

[0037] Decorative panel system: vertical aluminum column head C1A, horizontal aluminum column head C1B, decorative aluminum panel C2, first aluminum panel subframe C3A, second aluminum panel subframe C3B, EPDM adhesive strip C4, silicone weather-resistant sealant C5, bolt fasteners C6, screw fasteners C7, rubber gaskets C8; connecting support D1 for connecting the curtain wall to the main building structure, main building structural beam D2.

[0038] The specific implementation method of the open-joint waterproof aluminum panel curtain wall is as follows:

[0039] Frame System: The frame system is the foundation, upon which all subsequent systems are installed sequentially. The frame consists of vertical steel square tube columns A1 and horizontal steel square tube beams A2. Column A1 is suspended from the side of the main building structural beam D2 by connecting support D1, with the column centerline aligned with the design grid division point. The steel square tube beam A2 is connected to column A1 via a hinged connection at one end and a rigid connection at the other. Specifically, the right end of the steel square tube beam A2 is bolted to a steel angle bracket A3 welded to the left side of column A1 using bolt fastener A4. The steel angle bracket A3 is symmetrically arranged vertically along the horizontal centerline of beam A2. The connecting holes of the steel angle bracket A3 are machined into horizontal strip holes, allowing the beam to freely expand and contract horizontally, thus meeting the hinged connection requirements of standard specifications. The left end of beam A2 is welded to the right side of column A1. Beam A2 is flush with the outer surface of column A1 near the waterproof aluminum plate B1, and its horizontal centerline is aligned with the design grid division point.

[0040] Waterproofing System: Waterproof aluminum panels B1 cover the outer surfaces of the frame system columns A1 and beams A2. The seams between the panels are sealed with silicone weather-resistant sealant for waterproofing. Horizontal seams are aligned with the centerline of beam A2, and vertical seams are aligned with the centerline of column A1, with a seam width of approximately 6mm. To prevent bimetallic chemical corrosion between the aluminum panels and steel, rubber gaskets B2 are placed on the contact surfaces between columns A1, beams A2, and the waterproof aluminum panels B1. Screws and fasteners B4 are arranged around the perimeter of the waterproof aluminum panels B1, and silicone weather-resistant sealant B3 is applied to the screw heads to prevent rainwater penetration. After the waterproof aluminum panels B1 are installed, the gaps between the aluminum panels are cleaned and filled with silicone weather-resistant sealant B3 for waterproofing.

[0041] Decorative panel system: After the waterproof system is installed, vertical aluminum column heads C1A are arranged along the vertical centerline of steel column A1, and horizontal aluminum column heads C1B are arranged along the horizontal centerline of steel beam A2. Vertical aluminum column heads C1A are arranged along the entire length, and horizontal aluminum column heads C1B are arranged between adjacent vertical aluminum column heads C1A. The profile openings of both the horizontal and vertical aluminum column heads are as follows... Figure 8 , Figure 9 The aluminum columns are arranged in the direction shown, facing the decorative aluminum panel C2. Rubber pads C8 are placed on the contact surfaces between the aluminum column heads C1A and C1B and the waterproof aluminum panel B1. The aluminum column heads C1A and C1B are fixed to the frame system with screws C7, with a screw spacing of 300-350mm. After installation, the screw heads are sealed with silicone weather-resistant sealant C5 for waterproofing. Before installing the decorative aluminum panel C2 on the wall, the first aluminum subframe C3A and the second aluminum subframe C3B are fixed to the left and lower folded edges and the right and upper folded edges of the decorative aluminum panel C2 respectively using bolts C6 on a workbench on the ground. This placement is crucial; otherwise, the aluminum column heads cannot be attached. To prevent friction noise between the contact surfaces of the first aluminum subframe C3A and C3B and the aluminum column heads C1A and C1B, EPDM adhesive strips C4 are placed inside the profile grooves of the first aluminum subframe C3A and C3B. After these processes on the workbench are completed, the assembled decorative aluminum panel C2 is hung on the aluminum column heads C1A and C1B in a counterclockwise order from left to right and from bottom to top. The decorative aluminum panel C2 is then hung on the slots of the vertical aluminum column head C1A and the horizontal aluminum column head C1B through the first aluminum plate subframe C3A and the second aluminum plate subframe C3B.
