Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically a waterproof structure for building curtain walls. Background Technology

[0002] A building curtain wall is a non-load-bearing exterior enclosure structure of a building, mainly composed of front panel materials and a rear support system. With changing market demands, building curtain walls are gradually shifting from using heavier materials to lighter panels and structures.

[0003] Extensive searches revealed CN218116795U, which discloses a waterproof sealing structure for building curtain walls. This structure not only facilitates ventilation and heat dissipation but also makes it easy to disassemble and assemble the mounting frame, thus facilitating future maintenance.

[0004] In existing technologies, when curtain wall structures are used in rainy weather, the ventilation channels are sealed to prevent rain damage. This causes the curtain wall structure to lose its ventilation function in rainy weather, so a waterproof curtain wall structure is needed to solve the above problem. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof structure for building curtain walls that has the advantages of maintaining ventilation and breathability in rainy weather while also providing waterproof functionality, thus solving the problem in the prior art where curtain wall structures cannot be ventilated in rainy weather in order to provide waterproofing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for building curtain walls, including a frame, with a first guide channel and a second guide channel fixedly installed on the inner side of the frame from top to bottom, a first reserved hole equidistantly opened at the top of the frame, and a second reserved hole opened at the bottom of the frame, the first reserved hole and the second reserved hole respectively penetrating the upper and lower ends of the frame.

[0007] The top of the first guide channel adopts an open structure design, and there are openings on both sides of the bottom of the first guide channel. The length of the top of the first guide channel matches the length of the top of the inner side of the frame.

[0008] The bottom of the second guide channel adopts an open structure design, and there are openings on both sides of the top of the second guide channel. The bottom length of the second guide channel matches the bottom length of the inner side of the frame, and the upper end face of the second guide channel is fitted onto the outer side of the lower end face of the first guide channel.

[0009] Preferably, the curtain wall glass is bonded to the back of the frame with structural adhesive, and mounting holes are provided on the outer side of the front of the frame. Through-hole limiting holes are also provided on both sides of the top and bottom of the frame. This design, where the curtain wall glass is bonded to the back of the frame with structural adhesive, not only enhances the overall stability of the curtain wall structure but also ensures the seal between the curtain wall glass and the frame, effectively preventing rainwater penetration. Simultaneously, the mounting holes on the outer side of the front of the frame facilitate the use of mounting bolts to fix the frame and its internal curtain wall glass to the building facade, while the through-hole limiting holes at the top and bottom of the frame facilitate the fixed installation of the first and second drainage channels, ensuring the stability of the entire waterproof structure.

[0010] Preferably, the mounting holes are designed with an elliptical structure, and mounting bolts are movably inserted into the mounting holes. The frame is fixed to the building facade by the mounting bolts movably inserted into the mounting holes. The elliptical structure of the mounting holes allows for some adjustment of the mounting bolts during installation, enabling more flexibility to adapt to unevenness or installation errors on the building facade. This ensures that the frame and its internal curtain wall glass fit tightly against the building facade, further improving waterproofing performance.

[0011] Preferably, the first guide channel has first positioning holes on both sides of its top, and the positions of the first positioning holes match the positions of the limiting holes on the top of the frame. This design allows the first guide channel to be accurately and securely installed on the top of the frame, ensuring that rainwater can be smoothly introduced into the first guide channel and flow along its body to the openings on both sides of the bottom, thereby effectively preventing rainwater infiltration.

[0012] Preferably, the second guide channel has second positioning holes on both sides of its bottom, which match the positions of the limiting holes at the bottom of the frame. The inner diameter of the openings on both sides of the top of the second guide channel is larger than the outer diameter of the openings on both sides of the bottom of the first guide channel. This design not only ensures the accurate and stable installation of the second guide channel at the bottom of the frame, but also guarantees a smooth connection between the first and second guide channels, allowing rainwater to flow smoothly from the first guide channel into the second guide channel and ultimately exit the curtain wall system. Simultaneously, the opening size design ensures free airflow within the gap between the first and second guide channels, maintaining the ventilation function of the curtain wall.

[0013] Preferably, a rivet is movably inserted into the limiting hole, passing through the limiting hole and anchored in the first or second positioning hole. In this design, the rivet is movably inserted into the limiting hole, passing through the limiting hole and anchored in the first or second positioning hole. This design, through the fixing effect of the rivet, further enhances the connection stability between the first and second flow guide channels and the frame, ensuring the reliability and durability of the entire waterproof structure. At the same time, the installation of the rivet facilitates later maintenance and replacement work, improving the maintainability of the curtain wall structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the top of the first guide channel adopts an open structure design, which can quickly collect rainwater falling from the top of the curtain wall. Openings are provided on both sides of its bottom, allowing the collected rainwater to flow smoothly to the second guide channel. The bottom of the second guide channel also adopts an open structure design, capable of receiving rainwater flowing from the first guide channel and smoothly draining it out of the curtain wall system through its open bottom design. First reserved holes are equidistantly opened at the top of the frame; these holes are not only for ventilation but also ensure that air can enter the first guide channel. Second reserved holes at the bottom of the frame are used for the drainage function of the second guide channel, ensuring that rainwater can be smoothly drained from the curtain wall system and avoiding leakage problems caused by water accumulation. The top length of the first guide channel matches the inner top length of the frame, ensuring that rainwater can be completely covered and collected. The upper end face of the second guide channel fits onto the outer side of the lower end face of the first guide channel; this nested design not only enhances the stability of the structure but also ensures the smooth flow of rainwater during the guiding process.

[0016] The openings on both sides of the bottom of the first guide channel and the openings on both sides of the top of the second guide channel not only facilitate the smooth flow of rainwater but also increase the channels for air circulation to a certain extent. These openings can quickly guide rainwater during rainy weather and also serve as channels for air circulation, enhancing the ventilation and breathability of the curtain wall. In summary, this building's curtain wall waterproofing structure, through the design of the first and second guide channels and the gap design, achieves the goal of simultaneously providing waterproofing and ventilation functions during rainy weather. This design not only improves the practicality and comfort of the curtain wall but also solves the problem in existing technologies where curtain wall structures lose ventilation and breathability in order to achieve waterproofing during rainy weather.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a waterproof structure for building curtain walls, including a frame 1, with a first guide channel 2 and a second guide channel 3 fixedly installed on the inner side of the frame 1 from top to bottom, a first reserved hole 11 is provided at equal intervals at the top of the frame 1, and a second reserved hole 14 is provided at the bottom of the frame 1, with the first reserved hole 11 and the second reserved hole 14 respectively penetrating through the upper and lower ends of the frame 1.

[0025] The top of the first guide channel 2 adopts an open structure design, and there are openings on both sides of the bottom of the first guide channel 2. The top length of the first guide channel 2 matches the top length of the inner side of the frame 1.

[0026] The bottom of the second guide channel 3 adopts an open structure design. Both sides of the top of the second guide channel 3 are provided with openings. The bottom length of the second guide channel 3 matches the bottom length of the inner side of the frame 1. The upper end face of the second guide channel 3 is fitted onto the outer side of the lower end face of the first guide channel 2.

[0027] Specifically, the first guide channel 2 features an open top design to quickly collect rainwater falling from the top of the curtain wall. Openings on both sides of its bottom allow the collected rainwater to flow smoothly into the second guide channel 3. The second guide channel 3 also features an open bottom design to receive rainwater from the first guide channel 2 and, through its open bottom, to smoothly drain the rainwater from the curtain wall system. The top of the frame 1 has equidistant first pre-reserved holes 11, which are not only for ventilation but also ensure air can enter the first guide channel 2. The second pre-reserved holes 14 at the bottom of the frame 1 are used for drainage in the second guide channel 3, ensuring rainwater can be smoothly drained from the curtain wall system and preventing leakage caused by water accumulation. The top length of the first guide channel 2 matches the inner top length of the frame 1, ensuring complete coverage and collection of rainwater. The upper end of the second guide channel 3 is fitted over the lower end of the first guide channel 2; this nested design not only enhances the structural stability but also ensures smooth rainwater flow during the guide process.

[0028] The openings on both sides of the bottom of the first guide channel 2 and the openings on both sides of the top of the second guide channel 3 not only facilitate the smooth flow of rainwater but also increase the channels for air circulation to a certain extent. These openings can quickly guide rainwater during rainy weather and also serve as channels for air circulation, enhancing the ventilation and breathability of the curtain wall. In summary, the waterproof structure of this building's curtain wall, through the design of the first guide channel 2 and the second guide channel 3, as well as the gap design, achieves the goal of combining waterproofing and ventilation functions during rainy weather. This design not only improves the practicality and comfort of the curtain wall but also solves the problem in existing technologies where curtain wall structures lose ventilation and breathability in order to achieve waterproofing during rainy weather.

[0029] Example 2

[0030] To ensure stability when installing structural connections within the frame, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the curtain wall glass 5 is bonded to the back of the frame 1 with structural adhesive. Mounting holes 12 are provided on the outer side of the front of the frame 1, and through-holes 13 are provided on both sides of the upper and lower ends of the frame 1. The design of bonding the curtain wall glass 5 to the back of the frame 1 with structural adhesive not only enhances the overall stability of the curtain wall structure but also ensures the seal between the curtain wall glass 5 and the frame 1, effectively preventing rainwater penetration. Simultaneously, the mounting holes 12 on the outer side of the front of the frame 1 facilitate the use of mounting bolts to fix the frame 1 and its internal curtain wall glass 5 onto the building facade, while the through-holes 13 at the upper and lower ends of the frame 1 facilitate the fixed installation of the first and second drainage channels 2 and 3, ensuring the stability of the entire waterproof structure.

[0031] Furthermore, the mounting holes 12 adopt an elliptical structure design, and mounting bolts are movably inserted into the mounting holes 12. The frame 1 is fixedly installed on the building facade through the mounting bolts movably inserted into the mounting holes 12. The elliptical structure design of the mounting holes 12 allows the mounting bolts a certain amount of adjustment space during installation, enabling them to more flexibly adapt to unevenness or installation errors on the building facade. This ensures that the frame 1 and the curtain wall glass 5 inside can fit tightly against the building facade, further improving waterproof performance.

[0032] Furthermore, first positioning holes 21 are respectively provided on both sides of the top of the first guide channel 2, and the positions of the first positioning holes 21 match the positions of the limiting holes 13 on the top of the frame 1. In this design, the first guide channel 2 is provided on both sides of the top, and the positions of the first positioning holes 21 match the positions of the limiting holes 13 on the top of the frame 1. This design allows the first guide channel 2 to be accurately and securely installed on the top of the frame 1, ensuring that rainwater can be smoothly introduced into the first guide channel 2 and flow along its body to the openings on both sides of the bottom, thereby effectively preventing rainwater penetration.

[0033] Furthermore, second positioning holes 31 are respectively opened on both sides of the bottom of the second guide channel 3. The positions of the second positioning holes 31 match the opening positions of the limiting holes 13 at the bottom of the frame 1. The inner diameter of the openings on both sides of the top of the second guide channel 3 is larger than the outer diameter of the openings on both sides of the bottom of the first guide channel 2. In this design, the second positioning holes 31 are respectively opened on both sides of the bottom of the second guide channel 3, and their positions match the opening positions of the limiting holes 13 at the bottom of the frame 1. At the same time, the inner diameter of the openings on both sides of the top of the second guide channel 3 is larger than the outer diameter of the openings on both sides of the bottom of the first guide channel 2. This design not only allows the second guide channel 3 to be accurately and stably installed at the bottom of the frame 1, but also ensures a smooth connection between the first guide channel 2 and the second guide channel 3, allowing rainwater to flow smoothly from the first guide channel 2 into the second guide channel 3 and finally be discharged from the curtain wall system. At the same time, the opening size design also ensures that air can circulate freely in the gap between the first guide channel 2 and the second guide channel 3, maintaining the ventilation function of the curtain wall.

[0034] Furthermore, a rivet 4 is movably inserted into the limiting hole 13, passing through the limiting hole 13 and anchored in the first positioning hole 21 or the second positioning hole 31. In this design, the rivet 4 is movably inserted into the limiting hole 13, passing through the limiting hole 13 and anchored in the first positioning hole 21 or the second positioning hole 31. This design, through the fixing effect of the rivet 4, further enhances the connection stability between the first guide channel 2 and the second guide channel 3 and the frame 1, ensuring the reliability and durability of the entire waterproof structure. At the same time, the installation of the rivet 4 facilitates later maintenance and replacement work, improving the maintainability of the curtain wall structure.

[0035] When using this utility model, ensure the integrity of frame 1, check whether the first reserved hole 11, the second reserved hole 14, the mounting hole 12, and the limiting hole 13 are unobstructed, and check whether the dimensions of the first guide channel 2 and the second guide channel 3 match those of frame 1 to ensure smooth installation. Use rivets 4 to fix the first guide channel 2 onto frame 1 through the limiting hole 13 at the top of frame 1 and the first positioning holes 21 on both sides of the first guide channel 2. Use rivets 4 to fix the second guide channel 3 onto frame 1 through the limiting hole 13 at the bottom of frame 1 and the second positioning holes 31 on both sides of the second guide channel 3, ensuring that the openings on both sides of the top of the second guide channel 3 can smoothly fit over the bottom opening of the first guide channel 2. Structural adhesive is applied to the back of the curtain wall, and then the curtain wall glass 5 is pasted onto the frame 1, ensuring a tight fit between the curtain wall glass 5 and the frame 1. Using mounting bolts, the frame 1, its internal drainage channels, and the curtain wall glass 5 are fixed together on the exterior facade of the building. When rainwater falls on the curtain wall, the rainwater first enters the first drainage channel 2 and flows along its channel to the openings on both sides of the bottom. The rainwater enters the second drainage channel 3 from the opening of the first drainage channel 2 and continues to flow along its channel to the bottom opening, and finally exits the curtain wall system. At the same time, since there is a certain gap between the first drainage channel 2 and the second drainage channel 3, air can circulate freely inside and outside the curtain wall through these gaps, maintaining the ventilation function of the curtain wall.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
