Description

Technical Field

[0001] The present application relates to the field of steel structure building curtain walls, and in particular to a curtain wall aluminum plate drainage system and a construction method thereof. Background Art

[0002] Steel structures are green and energy-efficient buildings, with advantages such as their industrialization and short construction cycles, which effectively improve the return on capital investment and maintain a civilized construction site. From a material performance perspective, steel structures are lightweight and compact, which improves building space utilization. Their high ductility also provides excellent seismic resistance. To meet people's demands for architectural form, aesthetics, and visual impact, special-shaped steel structures have emerged, incorporating innovative design concepts from designers. Currently, special-shaped steel structures are proliferating in large-scale industrial and public buildings, including factories, terminal halls, convention and exhibition centers, theaters, and stadiums. Examples include Shanghai Pudong Airport, the Guangzhou Gymnasium Main Hall, the Guangzhou Convention and Exhibition Center, and the National Centre for the Performing Arts. These buildings provide strong technical support for the construction of special-shaped steel structures. Effective drainage of rainwater is a common challenge in these large steel structures, and leakage is a particularly difficult problem to address.

[0003] The Chinese patent application number CN206971577U discloses a multi-curved curtain wall roof gutter structure. The structure comprises a gutter drainage unit arranged in an inclined configuration with a higher head and a lower tail. The gutter drainage unit comprises a first water channel with an inclined bottom surface, a horizontally arranged drainage channel with a first end connected to the first water channel, a second water channel with an inclined bottom surface connected to a second end of the drainage channel opposite the first end, a siphon rainwater scoop mounted on the bottom plate of the drainage channel, and a water retaining plate disposed at the connection between the drainage channel and the second water channel, with the top of the water retaining plate being spaced a certain distance from the top of the second water channel. The siphon rainwater scoop is disposed within the horizontally arranged drainage channel, and the design of the water retaining plate enables an effective siphon to form within the drainage channel and promptly drain water from the roof, thereby reducing the possibility of leakage.

[0004] Regarding the above-mentioned related technologies, although the possibility of water leakage on the roof is reduced to a certain extent by setting up drainage grooves, for the connection parts between the special-shaped steel structure curtain walls, the setting of the drainage system in the related technologies is difficult to meet the drainage requirements of the special-shaped curved steel structure curtain wall system, which seriously affects the drainage performance of the entire curtain wall system. Summary of the Invention

[0005] In order to solve the problem that the drainage system in the related art is difficult to meet the drainage requirements of the connection part of the special-shaped curved steel structure curtain wall, thereby seriously affecting the drainage performance of the entire curtain wall system, the present application provides a curtain wall aluminum plate drainage system and its construction method.

[0006] In the first aspect, the present application provides a curtain wall aluminum plate drainage system adopting the following technical solutions:

[0007] A curtain wall aluminum plate drainage system, comprising:

[0008] A connecting mechanism, one end of which is used to be fixedly connected to the steel structure building, and the other end of which is used to be connected to the curtain wall aluminum plate. The end of the connecting mechanism used to be connected to the curtain wall aluminum plate is provided with a drainage space, which is arranged in a vertical direction and is used for drainage at the junction of the curtain wall system;

[0009] The hot air mechanism includes a hot air blower and a hot air pipe. The hot air blower is located at the bottom of the drainage space, and the hot air pipe is arranged in the drainage space. The hot air blower transmits hot air to the drainage space through the hot air pipe.

[0010] By adopting the above technical solution, the curtain wall aluminum panel is connected to the steel structure building using a connecting mechanism. After the connection is completed, the hot air mechanism is installed in the drainage space formed between the two curtain wall aluminum panels. The top of the drainage space is close to the UHPC panel of the steel structure building. In rainy or plum rain seasons, the hot air blower is started and blows hot air into the hot air pipe. The hot air flows from bottom to top in the hot air pipe. When it flows to the upper part of the drainage space, the hot air will squeeze the moisture attached to the connecting mechanism and the curtain wall aluminum panel downward in the drainage space. At this time, the moisture attached to the connecting mechanism and the curtain wall aluminum panel will flow downward along the curtain wall aluminum panel, effectively removing the moisture attached to the curtain wall aluminum panel. The moisture inside the two adjacent curtain wall aluminum panels is discharged into the drainage space, thereby effectively avoiding the possibility of moisture flowing from the drainage space into the interior of the steel structure building. When a lot of dust accumulates in the drainage space, the hot air blower is started. The hot air blower will blow hot air into the hot air pipe at this time. The hot air cleans the dust in the drainage space of the curtain wall aluminum panel, effectively reducing the possibility of dust accumulation in the steel structure building due to long-term non-use, thereby affecting the drainage effect of the drainage space. To a certain extent, it solves the problem that the setting of the drainage system in the relevant technology is difficult to meet the drainage requirements of the connection part of the special-shaped curved steel structure curtain wall, thereby seriously affecting the drainage performance of the entire curtain wall system.

[0011] Optionally, a guide plate is fixedly connected to the curtain wall aluminum plate, and the guide plate extends toward the hot air duct. The height of one end of the guide plate fixedly connected to the curtain wall aluminum plate is greater than the end of the guide plate away from the curtain wall aluminum plate.

[0012] By adopting the above technical solution and setting the drainage plate, the moisture attached to the curtain wall aluminum plate can be discharged more directly from the drainage space.

[0013] Optionally, an air guide plate is fixedly connected to the hot air pipe, and the air guide plate extends toward the curtain wall aluminum plate. The height of the air guide plate fixedly connected to one end of the hot air pipe is greater than the height of the air guide plate away from the end of the hot air pipe.

[0014] By adopting the above technical solution and setting the air guide plate, the hot air flowing in the drainage space can push the moisture attached to the curtain wall aluminum plate at multiple angles, so that the moisture attached to the curtain wall aluminum plate can be better discharged.

[0015] Optionally, a plurality of flow guide plates are provided in the vertical direction, a plurality of air guide plates are provided in the vertical direction, the plurality of flow guide plates correspond to the plurality of air guide plates one by one, and the plurality of flow guide plates and the plurality of air guide plates are staggered.

[0016] By adopting the above technical solution, multiple guide plates and multiple wind deflectors are staggered, so that the wind deflectors and the guide plates can better interact with each other, further improving the drainage capacity of the guide plates.

[0017] Optionally, the guide plate is further provided with a plurality of guide holes, and the plurality of guide holes are arranged close to the curtain wall aluminum plate.

[0018] By adopting the above technical solution and providing a plurality of drainage holes, the corners between the drainage plate and the curtain wall aluminum plate can also be pushed by the hot air passing through the drainage holes.

[0019] Optionally, a plug-in rod is provided at one end of the hot air pipe close to the steel structure building, and the plug-in rod is plugged into the connecting mechanism.

[0020] By adopting the above technical solution and setting the plug-in rod, firstly, it is ensured that the hot air pipe can stably allow hot air to pass through when working, and secondly, it is convenient for the installation of the hot air pipe.

[0021] Optionally, a water collecting tank is further included, which is located below the drainage space and is used to collect water in the drainage space.

[0022] By adopting the above technical solution and providing the water collecting tank, the water in the drainage space can be better collected, thereby reducing the possibility of water accumulating in the drainage space.

[0023] In a second aspect, the present application further provides a construction method for the curtain wall aluminum plate drainage system of the present application, comprising the following steps:

[0024] S1. Position and connect the connecting mechanism with the bolt holes reserved on the steel structure building through bolts;

[0025] S2. Position and connect the curtain wall aluminum panels with the bolt holes reserved on the connection mechanism through bolts;

[0026] S3. Push the hot air pipe into the drainage space and position it properly.

[0027] By adopting the above technical solution, only three simple steps, S1→S2→S3, are needed to realize the construction of the curtain wall aluminum plate drainage system. The entire construction process is simple and clear, and the operation is simple, which effectively improves the construction efficiency of the curtain wall aluminum plate drainage system.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Through the setting of the connecting mechanism and the hot air mechanism, firstly, when it is rainy or in the rainy season, the staff starts the hot air blower, and the hot air blower blows hot air into the hot air pipe. The hot air flows from bottom to top in the hot air pipe. When it flows to the upper part of the drainage space, the hot air squeezes the moisture attached to the connecting mechanism and the curtain wall aluminum plate downward in the drainage space. At this time, the moisture attached to the connecting mechanism and the curtain wall aluminum plate will flow downward along the curtain wall aluminum plate, effectively draining the moisture attached to the curtain wall aluminum plate from the moisture inside the two adjacent curtain wall aluminum plates to the drainage space, thereby effectively avoiding The first method is to reduce the possibility of moisture flowing from the drainage space into the interior of the steel structure building; secondly, when a large amount of dust accumulates in the drainage space, the hot air blower is started and blows hot air into the hot air pipe. The hot air cleans the dust in the drainage space of the curtain wall aluminum plate, effectively reducing the possibility of dust accumulation due to long-term disuse of the steel structure building, thereby affecting the drainage effect of the drainage space. To a certain extent, it solves the problem that the setting of the drainage system in the related art is difficult to meet the drainage requirements of the connection part of the special-shaped curved steel structure curtain wall, thereby seriously affecting the drainage performance of the entire curtain wall system.

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The embodiments of the present application disclose a curtain wall aluminum plate drainage system and a construction method thereof.

[0041] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In a first aspect, an embodiment of the present application discloses a curtain wall aluminum panel drainage system.

[0043] Reference Figure 1 、 Figure 2 and Figure 3 A drainage system for a curtain wall aluminum plate 200 includes a connecting mechanism 1 and a hot air mechanism 3. One end of the connecting mechanism 1 is used to be fixedly connected to a steel structure building 100, and the other end of the connecting mechanism 1 is used to be connected to the curtain wall aluminum plate 200. A drainage space 2 is provided at the end of the connecting mechanism 1 for connecting to the curtain wall aluminum plate 200. The drainage space 2 is arranged in a vertical direction and is used for drainage at the junction of the curtain wall system; the hot air mechanism 3 includes a hot air blower 31 and a hot air pipe 32. The hot air blower 31 is located at the bottom of the drainage space 2, and the hot air pipe 32 is arranged in the drainage space 2. The hot air blower 31 transfers hot air to the drainage space 2 through the hot air pipe 32.

[0044] The curtain wall aluminum panels 200 are connected to the steel structure building 100 using a connecting mechanism 1. After the connection is completed, the hot air mechanism 3 is installed in the drainage space 2 formed between the two curtain wall aluminum panels 200. The top of the drainage space 2 is close to the UHPC panel of the steel structure building 100. It should be noted that although the UHPC panel portion of the steel structure is not shown in the drawings of the embodiments of this application, this is because UHPC panels are a relatively common setting in the field. In this application, the UHPC panel is mainly used to block the hot air in the drainage space 2, allowing the hot air to flow better from top to bottom in the drainage space 2.

[0045] In the embodiment of the present application, the drainage system of the curtain wall aluminum plate 200 has multiple functions. First, in rainy or plum rain seasons, the hot air blower 31 is started, and the hot air blower 31 blows hot air into the hot air pipe 32. The hot air flows from bottom to top in the hot air pipe 32. When it flows to the upper part of the drainage space 2, the hot air will squeeze the moisture attached to the connecting mechanism 1 and the curtain wall aluminum plate 200 downward in the drainage space 2. At this time, the moisture attached to the connecting mechanism 1 and the curtain wall aluminum plate 200 will flow downward along the curtain wall aluminum plate 200, effectively draining the moisture attached to the curtain wall aluminum plate 200 from the moisture inside the two adjacent curtain wall aluminum plates 200 to the drainage space 2, thereby effectively avoiding the possibility of moisture flowing from the drainage space 2 into the interior of the steel structure building 100; second, the hot air mechanism 3 itself will generate a lot of heat, which is more convenient for drainage. The moisture in the space 2 is vaporized, and the vaporized water vapor is squeezed out of the drainage space 2 by the hot air because its temperature is not as high as that of the hot air, thereby effectively ensuring that the moisture in the drainage space 2 is quickly discharged; thirdly, when a lot of dust accumulates in the drainage space 2, the hot air blower 31 is started, and the hot air blower 31 will blow hot air into the hot air pipe 32 at this time. The hot air cleans the dust in the drainage space 2 of the curtain wall aluminum plate 200, effectively reducing the possibility of dust accumulation in the steel structure building 100 due to long-term non-use, thereby affecting the drainage effect of the drainage space 2. To a certain extent, it solves the problem that the setting of the drainage system in the related technology is difficult to meet the drainage requirements of the connection part of the special-shaped curved steel structure curtain wall, thereby seriously affecting the drainage performance of the entire curtain wall system.

[0046] Reference Figure 4 and Figure 5, a drain plate 4 is fixedly connected to the curtain wall aluminum plate 200, and the drain plate 4 extends in the direction of the hot air duct 32. The height of the drain plate 4 fixedly connected to one end of the curtain wall aluminum plate 200 is greater than the end of the drain plate 4 away from the curtain wall aluminum plate 200. The setting of the drain plate 4 allows the moisture attached to the curtain wall aluminum plate 200 to be discharged more directly from the drainage space 2. In the embodiment of the present application, the drain plate 4 and the curtain wall aluminum plate 200 are made of aluminum plates of the same material. Before installation, a certain angle needs to be set for drainage. In the embodiment of the present application, the drain plate 4 is set at a 60° angle downward to the curtain wall aluminum plate 200. In other embodiments, the drain plate 4 can also be set at other angles downward to the curtain wall aluminum plate 200.

[0047] Reference Figure 4 and Figure 5 The drainage plate 4 is also provided with a plurality of drainage holes 6, which are arranged near the curtain wall aluminum plate 200. The provision of the plurality of drainage holes 6 allows the hot air in the corners between the drainage plate 4 and the curtain wall aluminum plate 200 to be pushed by the hot air flowing through the drainage holes 6, thereby greatly reducing the situation where there are hard-to-clean dead corners on the curtain wall aluminum plate 200. It should be noted that in the embodiment of the present application, the drainage holes 6 are circular and evenly arranged. In other embodiments, the drainage holes can be holes of other shapes and sizes, and can also be unevenly arranged.

[0048] Reference Figure 4 and Figure 5 The hot air duct 32 is fixedly connected to an air guide plate 5, which extends toward the curtain wall aluminum panel 200. The height of the air guide plate 5 at the end fixed to the hot air duct 32 is greater than the height of the end away from the hot air duct 32. The arrangement of the air guide plate 5 allows the hot air flowing through the drainage space 2 to push moisture attached to the curtain wall aluminum panel 200 from multiple angles, thereby effectively draining the moisture attached to the curtain wall aluminum panel 200.

[0049] Reference Figure 4 and Figure 5 The hot air pipe 32 is provided with a plug rod 7 at one end close to the steel structure building 100, and the plug rod 7 is plugged into the connecting mechanism 1. The setting of the plug rod 7 ensures that the hot air pipe 32 can stably let the hot air pass through during operation, and secondly facilitates the installation of the hot air pipe 32.

[0050] Reference Figure 4 and Figure 5 A plurality of guide plates 4 are provided in the vertical direction, and a plurality of air guide plates 5 are provided in the vertical direction. The plurality of guide plates 4 correspond to the plurality of air guide plates 5 one by one, and the plurality of guide plates 4 are staggered with the plurality of air guide plates 5. The staggered arrangement of the plurality of guide plates 4 and the plurality of air guide plates 5 allows the air guide plates 5 and the guide plates 4 to better interact with each other, further improving the drainage capacity of the guide plates 4.

[0051] It should be noted that, in all embodiments, the arrangement of the plurality of flow guide plates 4 and the plurality of wind guide plates 5 needs to be determined according to the size of the drainage space 2 formed by two actual adjacent curtain wall aluminum panels 200 .

[0052] Reference Figure 4 and Figure 5 , further comprising a water collecting tank 8, which is located below the drainage space 2 and is used to collect water in the drainage space 2. The provision of the water collecting tank 8 enables the water in the drainage space 2 to be better collected, thereby reducing the possibility of water accumulating in the drainage space 2.

[0053] In a second aspect, the present application further provides a construction method for the drainage system of the curtain wall aluminum plate 200 of the present application, comprising the following steps:

[0054] Reference Figure 1 、 Figure 4 and Figure 5

[0055] S1. Position and connect the connecting mechanism 1 with the bolt 300 holes reserved on the steel structure building 100 through the bolts 300;

[0056] S2. Position and connect the curtain wall aluminum plate 200 with the bolt 300 holes reserved on the connection mechanism 1 through the bolts 300;

[0057] S3. Push the hot air pipe 32 into the drainage space 2 and position it properly.

[0058] In S1, on-site construction workers use the bolt 300 holes reserved on the steel structure building 100 to position and install the connecting mechanism 1 on the steel structure building 100 through the bolt 300. It should be noted that a buffer part also needs to be installed on the connecting mechanism 1 to ensure the stability of the connecting mechanism 1.

[0059] In S2 , the on-site construction workers position and connect the curtain wall aluminum plate 200 with the bolt 300 holes reserved on the connection mechanism 1 through the bolts 300 , so that the two adjacent aluminum plates and the UHPC plate of the steel structure building 100 form a drainage space 2 .

[0060] During the process between S2 and S3, according to the design requirements, the drainage plate 4 is welded on the opposite side of the curtain wall aluminum plate 200 where it is connected to the connecting mechanism 1. The angle between the drainage plate 4 and the curtain wall aluminum plate 200 and its own size are determined by the size of the drainage space 2. At the same time, the size and dimensions of the drainage hole 6 are also pre-set, and the drainage hole 6 needs to be arranged before welding the drainage plate 4.

[0061] During the process between S2 and S3, according to the design requirements, an air guide plate 5 is welded on the wall of the hot air pipe 32. The angle between the air guide plate 5 and the wall of the hot air pipe 32 and its own size are determined by the size of the drainage space 2 and the setting of the guide plate 4.

[0062] In S3, the on-site construction personnel align the plug-in rod 7 with the plug-in portion of the connecting mechanism 1, push the air guide mechanism in and position it on the connecting mechanism 1, thereby completing the construction and installation of the entire curtain wall aluminum panel 200 drainage system.

[0063] In the embodiment of the present application, only three simple steps S1→S2→S3 are needed to realize the construction of the curtain wall aluminum plate 200 drainage system. The entire construction process is simple and clear, and the operation is simple, which effectively improves the construction efficiency of the curtain wall aluminum plate 200 drainage system.

[0064] The implementation principle of a curtain wall aluminum plate 200 drainage system and a construction method thereof in an embodiment of the present application is as follows: when it is necessary to clean and discharge the moisture in the connection part of the curtain wall aluminum plate 200, the hot air blower 31 is started through the setting of the drainage space 2 formed between the connection mechanism 1 and the UHPC plate of the building steel structure and the hot air mechanism 3, so that the hot air is used to squeeze the moisture in the drainage space 2, thereby discharging the moisture attached to the side wall of the curtain wall aluminum plate 200 from top to bottom, thereby solving to a certain extent the problem that the setting of the drainage system in the related art is difficult to meet the drainage requirements of the connection part of the special-shaped curved steel structure curtain wall, thereby seriously affecting the drainage performance of the entire curtain wall system.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
