Description

Technical Field

[0001] This utility model relates to the field of composite panel technology, and in particular to a waterproof and breathable composite panel for steel structure curtain walls. Background Technology

[0002] In the field of modern architecture, steel structure curtain walls are widely used in various large public buildings, commercial complexes and high-rise buildings due to their unique aesthetics, good spatial performance and high construction efficiency.

[0003] Currently, the main method for connecting waterproof and breathable composite panels in steel structure curtain walls is to directly attach them to the curtain wall frame using self-tapping screws. However, this connection method has significant drawbacks. Gaps easily appear at the connection points between the self-tapping screws and the composite panels and curtain wall frame. During rainy weather, rainwater can seep into the building through these gaps, causing leaks and severely impacting the building's normal use and the safety of its internal facilities. Furthermore, the joints between the waterproof and breathable composite panels are typically sealed with sealant. Over time, this sealant ages and loses its original sealing properties, leading to water seepage at the joints and ultimately causing curtain wall leaks. Moreover, once leaks occur, the aged sealant is difficult to clean, making repairs cumbersome and complex. This not only requires significant manpower, resources, and time but also severely impacts the building's appearance and normal use.

[0004] To address the shortcomings of the aforementioned technologies, we propose a waterproof and breathable composite panel for steel structure curtain walls. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof and breathable composite panel for steel structure curtain walls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof and breathable composite panel for steel structure curtain walls includes a waterproof and breathable composite panel, an outer sealing assembly, and a connecting assembly. The connecting assembly includes a screw rod, with an inner nut and an outer nut screwed onto the outer wall of the screw rod. A plate base is fixedly installed at the outer end of the screw rod, and a sliding groove plate is slidably sleeved on the outer side of the plate base. A side plate is fixedly connected to the side end of the sliding groove plate, and several mounting holes are opened on the side wall of the side plate. A positioning screw rod is screwed onto the sliding groove plate, and connecting holes are opened at the four corners of the waterproof and breathable composite panel, with the screw rod inserted into the inner side of the connecting holes.

[0008] Furthermore, rubber washers are provided on the opposing surfaces of both the inner and outer nuts.

[0009] Furthermore, the screw, inner nut, outer nut, plate base, slide plate, and side plate are all made of high-strength stainless steel.

[0010] Furthermore, the waterproof and breathable composite panel for the curtain wall includes an aluminum alloy plate, and the inner side of the aluminum alloy plate is sequentially fixedly connected with an expanded polytetrafluoroethylene membrane, a fireproof rock wool insulation board, and a galvanized steel back plate.

[0011] Furthermore, the outer surface of the aluminum alloy plate is coated with a fluorocarbon coating.

[0012] Furthermore, raised cones are evenly distributed on the outer side of the aluminum alloy plate, and ventilation micro-holes are opened at the port of the raised cones, which penetrate to the back of the galvanized steel back plate.

[0013] Furthermore, the outer ring sealing assembly includes a rubber protective frame, and a plurality of raised outer frame rings are evenly distributed on the outer side surface of the rubber protective frame.

[0014] Compared with related technologies, the waterproof and breathable composite panel for steel structure curtain walls proposed in this utility model has the following beneficial effects:

[0015] In this utility model, a waterproof and breathable composite panel for steel structure curtain walls is provided. Through a connecting assembly, a screw passes through the connecting hole of the composite panel. Rubber washers are placed at the connection points of the screw and the nuts inside and outside the connecting hole, providing double waterproof protection at the connection point and improving the waterproofness of the joint. The sliding plate in the connecting assembly has a sliding adjustment function between itself and the panel base, allowing for a certain range of construction error adjustment and facilitating later installation. Furthermore, an outer ring sealing assembly is provided around the outer ring of the composite panel. At the junctions between the composite panels, several protruding outer rings of the rubber protective frame abut against each other, forming several waterproof rings. This significantly improves the waterproof sealing at the junctions of the composite panels. Compared to traditional glue application methods, the rubber protective frame has better durability and is easier to replace later. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-7 A waterproof and breathable composite panel for steel structure curtain walls includes a waterproof and breathable composite panel 1, an outer ring sealing component 2, and a connecting component 3. The connecting component 3 includes a screw 31, an inner nut 32 and an outer nut 33 screwed onto the outer wall of the screw 31, a plate base 35 fixedly installed on the outer end of the screw 31, a sliding groove plate 36 slidably sleeved on the outer side of the plate base 35, a side plate 37 fixedly connected to the side end of the sliding groove plate 36, a plurality of mounting holes 39 opened on the side wall of the side plate 37, a positioning screw 38 screwed onto the sliding groove plate 36, and connecting holes 16 opened at the four corners of the waterproof and breathable composite panel 1, with the screw inserted into the inner side of the connecting holes 16.

[0026] In this method, the waterproof and breathable composite panel 1 of the curtain wall includes an aluminum alloy plate 12, and an expanded polytetrafluoroethylene membrane 13, a fireproof rock wool insulation board 14 and a galvanized steel back plate 15 are fixedly connected to the inner side of the aluminum alloy plate 12 in sequence.

[0027] Through the above-mentioned configuration, the aluminum alloy plate 12 has excellent weather resistance, corrosion resistance and self-cleaning properties, the expanded polytetrafluoroethylene membrane 13 has extremely low water vapor permeation resistance and can withstand large water pressure, with a waterproof rating of IPX7 or higher, the fireproof rock wool insulation board 14 has good thermal insulation and fire resistance, and the galvanized steel back plate 15 provides support and protection.

[0028] In this method, the outer surface of the aluminum alloy plate 12 is coated with a fluorocarbon coating 11.

[0029] The above-mentioned design improves the corrosion resistance of the outer side of the aluminum alloy plate 12.

[0030] In this method, raised cones 17 are evenly distributed on the outer side of the aluminum alloy plate 12, and ventilation micro-holes are opened at the port of the raised cones 17, which penetrate to the back of the galvanized steel back plate 15.

[0031] With the above-mentioned arrangement, the outer end of the breathable micropore is located outside the raised cone 17, and the raised cone 17 is higher than the outer surface of the aluminum alloy plate 12, so that the breathable micropore has a breathable function and at the same time has good waterproof performance.

[0032] In this method, rubber washers 34 are provided on the opposing surfaces of the inner nut 32 and the outer nut 33.

[0033] By setting it in the above manner, the connection between the screw 31 and the connecting hole 16 has a double waterproof barrier, which improves the waterproof performance.

[0034] In this method, the screw 31, inner nut 32, outer nut 33, plate base 35, slide plate 36 and side plate 37 are all made of high-strength stainless steel.

[0035] By using the above-mentioned design, the high-strength stainless steel material has high strength and strong corrosion resistance, which improves the service life of the entire connecting component 3.

[0036] In this method, the outer ring sealing assembly 2 includes a rubber protective frame 21, and a plurality of raised outer frame rings 22 are evenly distributed on the outer side surface of the rubber protective frame 21.

[0037] With the above-mentioned arrangement, at the junction between the waterproof and breathable composite panel 1 and the waterproof and breathable composite panel 1, several raised outer frame rings 22 of the rubber protective frame 21 abut against each other to form several waterproof rings, which greatly improves the waterproof sealing performance at the junction of the waterproof and breathable composite panel 1.

[0038] The working principle of the waterproof and breathable composite panel for steel structure curtain walls provided by this utility model is as follows:

[0039] When using:

[0040] I. Installation and Waterproofing Mechanism of Connecting Components

[0041] Screw connection and sealing

[0042] Installation process: The screw 31 passes through the connection holes 16 at the four corners of the curtain wall waterproof and breathable composite panel 1. It is fixed on the inside by the inner nut 32 and on the outside by the outer nut 33. Rubber washers 34 are placed on the opposite sides of the inner nut 32 and the outer nut 33. After tightening, the rubber washers 34 are squeezed and deformed, filling the gap between the screw 31 and the connection hole 16 to form a double seal and prevent rainwater from seeping in from the connection.

[0043] Adjustment function of the slide plate

[0044] A sliding groove plate 36 is slidably fitted on the outer side of the plate base 35. The side plate 37 is fixed to the curtain wall frame through the mounting hole 39. During construction, the position of the composite panel can be adjusted by sliding the sliding groove plate 36 to compensate for installation errors (such as frame size deviation, uneven splicing gap of composite panels, etc.). After adjustment, the sliding groove plate is fixed with the positioning screw 38 to ensure installation accuracy.

[0045] II. Waterproof Design of the Outer Ring Sealing Component

[0046] Rubber protective frame and raised outer frame

[0047] The composite board is wrapped with a rubber protective frame 21. The raised outer frame 22 on its outer surface is distributed in a ring. When adjacent composite boards are spliced, the raised outer frame on both sides abuts against each other to form a multi-layer sealing structure (similar to a "maze-like" waterproof design). When rainwater flows down the board surface, it will be blocked by the multi-layer raised outer frame and will be difficult to seep into the seam. Compared with the traditional glue application method, the sealing performance is more durable.

[0048] Durability and maintenance advantages

[0049] The rubber guard frame 21 is made of weather-resistant rubber, which has better anti-aging properties than sealant. It is not easy to crack or fail after long-term use. If maintenance is required later, you only need to remove the old guard frame and replace it with the new one. There is no need to clean up residual adhesive, which reduces maintenance costs.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
