Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a curtain wall drainage system. Background Technology

[0002] Curtain walls are a component of a building's external envelope, possessing specified load-bearing capacity, deformation capacity, and the ability to accommodate displacement of the main structure. Curtain walls are typically attached to the building's exterior via a curtain wall mounting system. In related technologies, this system includes horizontal beams, vertical columns, and snap-on covers. Curtain wall panels are connected to the horizontal beams and vertical columns. The snap-on covers are attached to the outside of the curtain wall panels, and the joints between the curtain wall panels and the vertical columns and horizontal beams require sealing with adhesive to achieve a waterproof effect.

[0003] However, this not only increases the amount of adhesive used, but also often results in missed areas due to the tight construction schedule of projects. Furthermore, over time, the adhesive area between the cover and the panel is prone to cracking, posing a risk of water leakage and potentially affecting the appearance of the curtain wall. Utility Model Content

[0004] In view of this, the present invention provides a curtain wall drainage system to solve the problems in related technologies, such as the large amount of adhesive used in curtain walls, the easy occurrence of missed areas, and the tendency for the adhesive to crack at the joint between the cover and the panel over time, posing a risk of water leakage and easily affecting the appearance of the curtain wall.

[0005] This utility model provides a curtain wall drainage system, including:

[0006] Columns;

[0007] The crossbeam connects to the column;

[0008] A pressure plate, connected to the column, has an opening formed on it;

[0009] A drainage channel is connected to the column and located between the column and the pressure plate. The drainage channel has a drainage outlet that passes through the opening.

[0010] Curtain wall panels are sandwiched between pressure plates and columns;

[0011] Thermal insulation strips are sandwiched between the pressure plate and the column. Sealing protrusions are formed on both sides of the thermal insulation strips, and the sealing protrusions abut against the curtain wall panel.

[0012] The cover is fastened to the outside of the pressure plate.

[0013] Beneficial Effects: The curtain wall drainage system of this utility model embodiment features a heat-insulating strip sandwiched between the pressure plate and the column, with sealing protrusions on both sides of the heat-insulating strip abutting against the curtain wall panel. This design not only provides heat insulation but also prevents water from entering through the gap between the pressure plate and the curtain wall panel. Furthermore, even if a small amount of water enters, it can be drained through the drainage channel between the pressure plate and the cover. This ensures a high level of waterproofing without the need for sealant between the cover and the curtain wall panel, and between the curtain wall panel and the heat-insulating strip, reducing the amount of sealant required for the curtain wall. This helps to improve construction progress, reduce construction costs, and lower the risk of sealant leakage. Moreover, since this application uses sealing protrusions instead of sealant to achieve a seal between the pressure plate and the curtain wall panel, it avoids cracking of the sealant area over time, preventing leaks and potential damage to the curtain wall's appearance, thus contributing to improved project quality.

[0014] In one alternative embodiment, each side of the thermal insulation strip is provided with at least two sealing protrusions, and the at least two sealing protrusions are spaced apart along the distance between the curtain wall panel and the column.

[0015] Beneficial effect: With this setup, at least two sealing protrusions can form at least two seals between the curtain wall panel and the thermal insulation strip, thereby improving the waterproofness of the curtain wall.

[0016] In one alternative embodiment, the curtain wall drainage system further includes a first screw that passes sequentially through the pressure plate and the thermal insulation strip to connect to the column.

[0017] In one alternative embodiment, a pressure plate connecting protrusion and a rubber strip connecting protrusion are formed on the column, an assembly groove is formed between the pressure plate connecting protrusion and the rubber strip connecting protrusion, and an assembly protrusion is formed on the drainage groove, the assembly protrusion being confined within the assembly groove.

[0018] Beneficial effect: With this setting, the drainage channel is embedded in the mounting slot on the column, which makes the connection between the column and the drainage channel tighter and ensures that the drainage channel can catch the water on the column.

[0019] In one alternative embodiment, a first adhesive strip groove is formed on the adhesive strip connecting protrusion, and the curtain wall drainage system further includes a first EPDM adhesive strip, which is disposed in the first adhesive strip groove.

[0020] Beneficial effects: First, EPDM adhesive strips can be used to reduce installation errors between columns and beams, forming an expansion joint between the columns and beams, which is beneficial for leveling the beams.

[0021] In one optional embodiment, a second adhesive strip groove is provided on the crossbeam, and the curtain wall drainage system further includes a second EPDM adhesive strip, which is disposed in the second adhesive strip groove.

[0022] Beneficial effects: The second EPDM sealing strip has excellent weather resistance and water resistance, effectively preventing rainwater and snowmelt from penetrating into the curtain wall system and ensuring the watertightness of the curtain wall. In addition, the second EPDM sealing strip can also effectively prevent air penetration, improving the airtightness of the curtain wall, reducing energy loss and energy consumption, while also preventing dust and sand from entering the interior of the curtain wall, maintaining a clean indoor environment.

[0023] In one optional embodiment, a waterproof adhesive layer is provided at the junction of the first EPDM adhesive strip and the second EPDM adhesive strip.

[0024] Beneficial effects: The waterproof adhesive layer between the first and second EPDM strips can further enhance the waterproof performance of the curtain wall.

[0025] In one alternative implementation, the drain groove slopes downwards along the direction approaching the cover.

[0026] Beneficial effects: The drainage channel is designed to slope downwards, which allows water in the drainage channel to flow into the space between the pressure plate and the cover under the action of gravity, and then be discharged through the cavity between the pressure plate and the cover.

[0027] In one alternative embodiment, the crossbeam is provided with pins that are connected to the column.

[0028] Beneficial effects: The pins can be connected to the columns, thereby limiting the movement between the beam and the column and preventing the beam from tipping over.

[0029] In one alternative implementation, the curtain wall panel is a laminated insulated glass panel. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0050] According to an embodiment of the present invention, a curtain wall drainage system is provided, including a column 1, a beam 2, a pressure plate 3, a drainage channel 4, a curtain wall panel 5, a thermal insulation strip 6, and a cover 7.

[0051] The crossbeam 2 is connected to the column 1. The pressure plate 3 is connected to the column 1 and has an opening. The drainage channel 4 is connected to the column 1 and is located between the column 1 and the pressure plate 3. The drainage channel 4 has a drainage outlet 401 that passes through the opening. The curtain wall panel 5 is sandwiched between the pressure plate 3 and the column 1. The thermal insulation strip 6 is sandwiched between the pressure plate 3 and the column 1, and sealing protrusions 601 are formed on both sides of the thermal insulation strip 6, abutting against the curtain wall panel 5. The cover 7 is fastened to the outside of the pressure plate 3.

[0052] The curtain wall drainage system of this utility model embodiment features a heat-insulating strip 6 sandwiched between the pressure plate 3 and the column 1. The sealing protrusions 601 on both sides of the heat-insulating strip 6 abut against the curtain wall panel 5. This design not only provides heat insulation but also prevents water from entering through the gap between the pressure plate 3 and the curtain wall panel 5. Furthermore, even if a small amount of water enters, it can be drained through the drainage channel 4 into the space between the pressure plate 3 and the cover 7. This ensures a high level of waterproofing without the need for sealant between the cover and the curtain wall panel 5, and between the curtain wall panel 5 and the heat-insulating strip 6. This reduces the amount of sealant required for the curtain wall, thereby improving construction progress, reducing construction costs, and lowering the risk of sealant leakage. Moreover, since this application uses the sealing protrusions 601 instead of sealant to achieve a seal between the pressure plate 3 and the curtain wall panel 5, it avoids the sealant area from cracking over time, causing leaks and affecting the appearance of the curtain wall, thus improving project quality.

[0053] In one embodiment, the crossbeam 2 is an aluminum alloy crossbeam, the column 1 is an aluminum alloy column, the pressure plate 3 is an aluminum alloy pressure plate, the cover 7 is an aluminum alloy cover, and the drainage trough 4 is an aluminum alloy drainage trough.

[0056] With this configuration, at least two sealing protrusions 601 can form at least two seals between the curtain wall panel 5 and the thermal insulation strip 6, thereby improving the waterproofness of the curtain wall.

[0057] As an alternative implementation, in an embodiment not shown in the accompanying drawings, each side of the heat-insulating strip 6 may also be provided with a sealing convex edge 601.

[0058] In one embodiment, such as Figure 4 As shown, the curtain wall drainage system also includes a first screw 8, which passes through the pressure plate 3 and the thermal insulation strip 6 in sequence to connect to the column 1.

An assembly protrusion 402 is formed on the drainage groove 4, and the assembly protrusion 402 is limited to the assembly groove 103.

[0060] With this arrangement, the drainage channel 4 is embedded in the mounting slot 103 on the column 1, which makes the connection between the column 1 and the drainage channel 4 tighter and ensures that the drainage channel 4 can receive the water on the column 1.

[0061] In one embodiment, the drainage channel 4 is also provided with screw connection points, which allow screws to pass through and connect the drainage channel 4 to the column 1.

[0062] In one embodiment, the drainage channel 4 is connected to the column 1 at the junction of the column 1 and the beam 2. The junction of the column 1 and the beam 2 is most prone to water seepage or leakage. By placing the drainage channel 4 at this location, it can be ensured that the drainage channel 4 can effectively receive and drain the seepage water, thereby preventing the seepage water from entering the room.

[0065] The first EPDM adhesive strip 9 can be used to reduce the installation error between the column 1 and the beam 2, forming an expansion joint between the column 1 and the beam 2, which is beneficial for leveling the beam 2.

[0066] In one embodiment, such as Figure 1 As shown, a second adhesive strip groove 201 is provided on the crossbeam 2, and the curtain wall drainage system also includes a second EPDM adhesive strip 10, which is located in the second adhesive strip groove 201.

In addition, the second EPDM sealing strip 10 can also effectively prevent air penetration, improving the air tightness of the curtain wall, reducing energy loss and energy consumption, while also preventing dust and sand from entering the interior of the curtain wall, maintaining a clean indoor environment.

[0068] In one embodiment, a waterproof adhesive layer is provided at the junction of the first EPDM adhesive strip 9 and the second EPDM adhesive strip 10.

[0069] The waterproof adhesive layer between the first EPDM strip 9 and the second EPDM strip 10 can further enhance the waterproof performance of the curtain wall.

[0070] Among them, the waterproof adhesive is preferably, but not limited to, silicone sealant.

[0071] In one embodiment, the drain groove 4 slopes downward along the direction close to the cover 7.

[0072] like Figure 1 and Figure 2 As shown, the drainage trough 4 is set to tilt downwards, which can guide the water in the drainage trough 4 to flow into the space between the pressure plate 3 and the cover 7 under the action of gravity, and then discharge it through the cavity between the pressure plate 3 and the cover 7.

[0073] In one embodiment, the crossbeam 2 is provided with a pin 202, which is connected to the column 1.

[0074] The pin 202 can be connected to the column 1, thereby limiting the position between the beam 2 and the column 1 and preventing the beam 2 from tipping over.

[0075] In one embodiment, the curtain wall drainage system further includes a second screw 11, which can pass through the beam 2 and connect to the column 1.

[0076] In one embodiment, the curtain wall panel 5 is a laminated insulated glass panel.

[0077] As an alternative implementation, in embodiments not shown in the accompanying drawings, the curtain wall panel 5 may also be selected as tempered glass, coated glass, aluminum plate, stainless steel plate, or ceramic plate, etc.
