Description

[Technical field]

[0001] The utility model relates to the technical field of air duct installation, in particular to an anti-leakage device used for air duct installation. [Background technology]

[0002] In modern architectural design, especially in large new buildings such as hospitals, office buildings, high-rise residential buildings and commercial cities, vertical wind shafts on the roof have become a common ventilation solution. These wind shafts are usually equipped with air ducts, which are connected to the room compartments on each floor inside the building. The fans installed on the roof realize air circulation and ventilation inside the building. To achieve this function, holes must be set on the side walls of the wind shaft for the air ducts to pass through.

[0003] However, since the construction of the air shaft often precedes the installation of the air duct, the size of the reserved hole on the side wall of the air shaft is usually designed to be slightly larger than the size of the air duct to facilitate the smooth installation of the air duct. But this also brings a problem: after the air duct is installed, the gap between the air duct and the hole needs to be sealed to prevent rainwater from seeping in.

[0004] At present, the existing technical solutions to this problem mainly use brickwork or cement mortar for sealing, and then hang mesh plastering. However, this solution has obvious shortcomings. First, because brickwork or cement mortar is plugged later, it is difficult to ensure the density during the filling process, and the mortar bonding layer is prone to shrinkage and cracking, which provides a leakage channel for rainwater. Once rainwater comes into contact with these pores or cracks, leakage is likely to occur. Secondly, because the wind shaft is in an open-air environment, the sealed part of the wind shaft is directly exposed to the outside, and no effective shielding measures are taken, which greatly increases the risk of leakage in the sealed part of the wind shaft. [Contents of the utility model]

[0011] In the anti-leakage device for air duct installation as described above, the panel is bent downward along one end of the cross bar close to the air shaft wall and fits against the air shaft wall, and the bent surface of the panel is fixedly connected to the vertical bar and the horizontal bar respectively through a third fastener.

[0012] In the anti-leakage device for air duct installation as described above, a rubber pad matching the bent surface is provided between the air shaft wall and the bent surface of the panel, and the rubber pad is fixedly connected to the bent surface of the panel via the third fastener.

[0013] In the anti-leakage device for air duct installation as described above, the horizontal projection surface of the panel is larger than and covers the horizontal projection surface of the air duct.

[0014] In the anti-leakage device for air duct installation as described above, the panel is a stainless steel plate, and the setting range of its slope i is between 2% and 15%, which is used to prevent rainwater from depositing.

[0026] Specific embodiments, such as Figures 1 to 3The anti-leakage device for air duct installation shown in the figure comprises an air shaft wall 1 and a reserved hole 2 opened on the air shaft wall 1, and an air duct 3 for ventilation and exhaust installed in the air shaft extends from the reserved hole 2. A water retaining device 4 is provided above the reserved hole 2 to shield the air duct 3, which can effectively isolate rainwater from the outside, prevent rainwater from directly contacting the air duct 3 and flowing into the blocked part between the reserved hole 2 and the air duct 3, and penetrate into the air shaft wall. The water retaining device 4 is connected to a supporting device 5, and the supporting device 5 is connected to the air shaft wall 1 to ensure the stability of the water retaining device 4 and enhance the overall structural stability of the present embodiment. This stability can effectively resist the influence of external wind and other natural forces, and ensure that the anti-leakage device can play a long-term and effective role. A leak-stopping device 6 is provided between the reserved hole 2 and the air duct 3, and the leak-stopping device 6 can effectively prevent rainwater or other liquids from penetrating through the gap between the reserved hole 2 and the air duct body 3, ensure that the air shaft does not leak, and improve the construction quality.

[0027] Preferably, the water retaining device 4 includes a panel 41, and the panel 41 is fixedly connected to the supporting device 5 by a first fastener 42. A waterproof glue seal 43 is provided on the connecting portion between the panel 41 and the first fastener 42 for covering. In this embodiment, the first fastener 42 is a self-tapping screw, which can make the water retaining device 4 more stable and reliable. A waterproof glue seal 43 is provided on the connecting portion between the panel 41 and the first fastener 42 for covering, which can effectively prevent rainwater or other liquids from penetrating through the connecting portion, thereby enhancing the waterproof performance of the entire water retaining device 4.

[0028] Preferably, the supporting device 5 includes a vertical pole 51 fixedly connected to the air shaft wall 1 by a second fastener 8, a cross bar 52 is fixedly connected to the upper end of the vertical pole 51, and the cross bar 52 is fixedly connected to the panel 41 by the first fastener 42. An inclined rod 53 is also provided between the vertical pole 51 and the cross bar 52 to form a keel frame with a triangular structure. In this embodiment, the second fastener 8 is selected from expansion bolts. The triangular structure has the characteristics of high stability and strong load-bearing capacity, so that the entire supporting device 5 can withstand large external forces and effectively prevent deformation or loosening caused by natural factors such as wind and rain, so that the anti-leakage device 4 can work stably for a long time, thereby improving the reliability of the entire anti-seepage device. The expansion bolts selected from the second fastener 8 have the advantages of easy installation and firm fixation, which can ensure that the supporting device 4 is quickly and accurately fixed on the air shaft wall 1, simplifying the installation process and improving the installation quality.

[0029] Preferably, the support device 5 includes a keel frame with a triangular structure formed by connecting vertical poles 51, horizontal poles 52 and diagonal poles 53, and the support device 5 also includes a horizontal pole 54. The vertical poles 51, horizontal poles 52, diagonal poles 53 and horizontal poles 54 are all made of galvanized angle steel bars. The galvanized angle steel bars not only have excellent strength and stability, but also their galvanized layer can effectively resist corrosion, ensuring that the device is not easy to rust or damage during long-term use. The horizontal pole 54 is vertically connected to the connecting end of the vertical poles 51 and the horizontal pole 52, so that each keel frame is connected as a whole, and the horizontal pole 54 is fixedly connected to the wind shaft wall 1 through the second fastener 8. The horizontal pole 54 connects each keel frame into a whole, which greatly enhances the structural stability of the support device 5. This multiple triangular structure design can effectively disperse and reduce external loads, reduce deformation and displacement caused by wind, vibration and other factors, and ensure that the anti-leakage device can work stably for a long time.

[0030] Preferably, the panel 41 is bent downward along the length direction of the cross bar 52 near the side edge of the wind shaft wall 1 to form a bent surface that fits the wind shaft wall 1, so that the gap between the panel 41 and the wind shaft wall 1 is greatly reduced, achieving a tighter fit, thereby effectively preventing rainwater or other liquids from penetrating into the wind shaft through the gap in the wind shaft wall 1, and the bent surface of the panel 41 is fixedly connected to the vertical pole 51 and the horizontal pole 54 respectively through a third fastener 9, wherein the third fastener 9 is a self-tapping screw, which makes the fixed connection between the panel 41 and the supporting device 5 simple, and the self-tapping screw can easily penetrate the panel 41 and be firmly fixed to the vertical pole 51 and the horizontal pole 54, without the need for pre-drilling or complicated operations, thereby improving installation efficiency.

[0031] Preferably, a rubber pad 71 matching the bending surface is provided between the air shaft wall 1 and the bending surface of the panel 41. The rubber pad 71 is fixedly connected to the bending surface of the panel 41 through the third fastener 9. The softness and elasticity of the rubber pad 71 can ensure a close fit with the air shaft wall 1 and the panel 41, thereby optimizing the waterproof structure and improving the sealing performance of the entire anti-leakage device.

[0032] Preferably, the horizontal projection surface of the panel 41 is larger than and covers the horizontal projection surface of the air duct 3, so that the panel 41 can completely block the air duct 3, effectively preventing rainwater from directly dripping onto the air duct 3 and penetrating into the construction joints of the wall hole sealing part, thereby reducing potential leakage points.

[0033] Preferably, the panel 41 is a stainless steel plate, and the setting range of its slope i is between 2% and 15%. In this embodiment, the slope is set to 2% to prevent rainwater deposition. The stainless steel plate has good processing performance and can be cut, bent and other processing operations according to actual needs to adapt to air ducts 3 of different shapes and sizes. In addition, the slope of the stainless steel plate can also be adjusted according to the on-site conditions to ensure the best drainage effect. This flexibility enables the anti-leakage device to adapt to various complex air duct 3 installation environments and improve construction efficiency.

[0034] Preferably, the joint between the upper end of the horizontal rod 54 and the wind shaft wall 1 is bonded with weather-resistant glue as the first sealant 72, which can effectively fill the tiny gap between the two and prevent rainwater or other liquids from penetrating through these gaps, thereby enhancing the sealing performance of the entire anti-leakage device. At the same time, it can also improve the ability of the entire anti-leakage device to resist external loads and enhance the structural stability.

[0035] Preferably, the leak-proof device 6 includes a sealing member 61 arranged between the air duct 3 and the reserved opening 2, and the cavity facing outward between the sealing member 61, the air duct 3 and the reserved opening 2 is filled with a second sealant 62. In this embodiment, a foam rod is selected as the sealing member 61, and weather-resistant glue is used as the second sealant 62. The double sealing design of the foam rod and the weather-resistant glue significantly improves the anti-seepage effect of the anti-leakage device. Compared with traditional cement mortar sealing, the construction process of using foam rods and weather-resistant glue to seal the construction opening is simpler and faster. At the same time, since the filling of weather-resistant glue can automatically adapt to reserved holes 2 of different shapes and sizes, the adjustment work during the sealing process is reduced, and the construction efficiency is greatly improved.

[0036] Principle of the utility model:

[0037] First, a stainless steel plate is selected as the panel material. The horizontal projection surface of the panel can completely cover and exceed the horizontal projection surface of the air duct. The panel is bent downward along the length of the crossbar to form a bending surface that fits the air shaft wall to ensure a close fit with the air shaft wall. A rubber pad is set between the panel and the air shaft wall to increase the sealing performance. In addition, weather-resistant glue is filled between the upper end of the panel and the air shaft wall to further prevent rainwater or other liquids from seeping in from the gap.

[0038] Then, install the support device to fix the panel. The support device includes components such as cross bars, vertical bars, diagonal bars and horizontal bars. The cross bars and vertical bars are fixed to the wind shaft wall by welding or bolting to form a stable frame. The horizontal bars are welded to the cross bars and connected to the panel. In order to improve the water-retaining and anti-seepage capabilities, the joints between the horizontal bars and the wind shaft wall are bonded with weather-resistant glue to ensure that there is no gap between the two. The diagonal bars are welded or bolted between the vertical bars and the cross bars to form a stable triangular structure.

[0039] In addition, in order to prevent leakage in the sealing part between the air duct and the reserved hole, a leak-proof device is also provided. The device includes a sealing piece, which uses a foam rod as a sealing material, is easy to process and install, and is placed between the air duct and the reserved hole to form a tight filling layer. The cavity facing outward between the sealing piece, the air duct and the reserved hole is filled with weather-resistant glue, which further improves the sealing of the sealing part to ensure the anti-seepage effect.

[0040] Through reasonable structural design, material selection and installation method, this device achieves multiple sealing of the blocked parts before and after the air duct installation, effectively preventing the infiltration of rainwater or other liquids. At the same time, the installation process is simple and efficient, which reduces the construction cost and improves the construction efficiency. In addition, the device also has the characteristics of stable structure and strong durability, and can maintain good sealing performance for a long time, providing a reliable anti-leakage solution for air duct installation or maintenance.
