Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane structures, specifically to a self-cleaning air-supported membrane structure roof. Background Technology

[0002] Air-supported membrane structures are environmentally friendly and energy-saving buildings that use a specially coated, waterproof, and corrosion-resistant membrane material as their outer shell. They support the main structure without traditional beams and columns by precisely controlling the indoor and outdoor air pressure difference, thus achieving low-carbon construction and operation. Air-supported membrane structures are characterized by low energy consumption and low pollution, and are widely used in stadiums, storage spaces, and other similar applications.

[0003] Currently, the roofs of air-supported membrane structures are usually directly exposed to the external environment. After long-term use, dust and debris easily accumulate on the surface, affecting the building's aesthetics and light transmission. Regular manual cleaning is required, which not only increases maintenance costs but also poses safety hazards for working at heights. Utility Model Content

[0004] The purpose of this utility model is to provide a self-cleaning air-supported membrane building roof structure to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The support member and the cover plate are detachably connected, and the edge of the air-supported membrane is clamped and fixed between the support member and the cover plate.

[0007] The cover plate has an inner cavity, and the outer circular surface of the inner cavity is connected to multiple connecting pipes. The connecting pipes extend to the outer wall of the cover plate and communicate with the outside. A fan communicating with the inside of the air film is installed on the bottom surface of the inner cavity. The support is annular and the outer wall is arc-shaped. The bottom opening of the support is corresponding to the position of the fan.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] First embodiment:

[0025] See Figures 1-2 As shown, this utility model provides a self-cleaning air-supported membrane building roof structure, including a support member 1 located inside the air-supported membrane and a cover plate 2 located outside the air-supported membrane. The support member 1 and the cover plate 2 are detachably connected, and the edge of the air-supported membrane is clamped and fixed between the support member 1 and the cover plate 2.

[0026] The cover plate 2 has an inner cavity 201 inside. Multiple connecting pipes 202 connected to its outer circular surface are connected at one end to the inner cavity 201 and at the other end to the outer wall of the cover plate 2 and connected to the outside, forming an airflow discharge channel. In actual use, the airflow in the inner cavity 201 can be evenly distributed and discharged through multiple connecting pipes 202, avoiding the airflow from concentrating and impacting the outer wall of the cover plate 2 due to exhaust through a single channel. At the same time, multiple connecting pipes 202 can expand the exhaust coverage area and improve the purging effect on impurities on the outer wall of the cover plate 2.

[0027] The fan 3 is installed on the bottom surface of the inner chamber 201 and is in communication with the inside of the air film. The opening at the bottom of the support 1 corresponds to the position of the fan 3, forming an airflow introduction path. When the fan 3 is started, the airflow inside the air film will enter the fan 3 through the opening at the bottom of the support 1. After being pressurized by the fan 3, it will be delivered to the inner chamber 201 and then discharged to the outer wall of the cover plate 2 through the connecting pipe 202. The entire airflow circulation process does not require the introduction of external gas and directly utilizes the gas inside the air film to achieve the self-cleaning function.

[0028] The support component 1 is ring-shaped and its outer wall is designed to be curved, which fits into the curved surface of the inner side of the air membrane. During installation, the curved outer wall of the support component 1 can make close contact with the inner side of the air membrane, increasing the contact area between the two and avoiding local protrusions of the support component 1 from causing squeezing damage to the air membrane. At the same time, the ring structure allows the support component 1 to distribute the force evenly around the top of the air membrane, preventing the air membrane from deforming due to excessive force on one side and ensuring the overall structural stability of the air membrane building roof.

[0029] During installation, the edge of the air membrane is first laid flat on the mating surface between the support 1 and the cover plate 2. Then, by tightening the connecting parts, the support 1 and the cover plate 2 are brought closer together, and finally the edge of the air membrane is clamped and fixed. After fixing the cover plate 2, the fan 3 is also fixed. This not only avoids damage to the edge of the air membrane due to uneven force, but also allows the air membrane to be quickly removed by disassembling the support 1 and the cover plate 2 when the air membrane needs to be inspected or replaced in the future, reducing the difficulty of maintenance operations.

[0030] The second embodiment differs from the first embodiment in that:

[0031] The curved surface 101 of the support member 1 is directly attached to the inner side of the air membrane, and the support ring 102 fixedly connected to its inner wall serves as a connecting carrier. It is detachably connected to the cover plate 2 by bolts. The curved surface 101 and the support ring 102 are integrally formed. When fixing the air membrane, the edge of the air membrane is precisely clamped between the support ring 102 and the cover plate 2. The support ring 102 can reduce the connection contact area, so that the bolt tightening force is more concentrated on the edge of the air membrane, further improving the sealing performance of the air membrane fixation, while avoiding deformation of the curved surface 101 of the support member 1 due to direct force.

[0032] The flexible ring fixed on the upper surface of the support ring 102 has a certain degree of elasticity, such as a silicone ring or a rubber ring. When the support ring 102 and the cover plate 2 clamp the edge of the air film, the flexible ring will be slightly squeezed, which can fill the tiny gap between the support ring 102 and the air film, enhance the airtightness, and prevent the rigid support ring 102 from directly contacting the air film and causing wear. The anti-slip texture on the upper surface of the flexible ring can increase the friction with the air film and prevent the air film from shifting due to airflow vibration or temperature changes during long-term use, ensuring that the edge of the air film is always in a stable clamped state.

[0033] The outer wall of the cover plate 2 is inclined, and the lower end of the inclined surface faces and is close to the axis of the cover plate 2. During the self-cleaning process, after the airflow discharged through the connecting pipe 202 blows away the impurities on the outer wall of the cover plate 2, the impurities slide naturally down the inclined surface to the vicinity of the axis of the cover plate 2, and then leave the cover plate 2 through the reserved channel at the axis, so as to avoid the accumulation of impurities on the outer wall of the cover plate 2 to form stubborn stains. At the same time, the inclined structure can also reduce the residence time of rainwater on the surface of the cover plate 2 and reduce the risk of rainwater infiltration.

[0034] The top surface of the cover plate 2 is part of a sphere. Its arc-shaped surface can disperse external impact forces and prevent the cover plate 2 from being damaged due to excessive local stress. At the same time, the spherical structure can further guide impurities to slide off the edge slope, forming a dual cleaning auxiliary effect of "spherical guidance + slope sliding" with the inclined outer wall. The hydrophobic coating on the outer wall surface of the cover plate 2 can reduce the adhesion between water and the surface of the cover plate 2, so that rainwater forms water droplets on the surface of the cover plate 2 and rolls off quickly, reducing the growth of scale or mold caused by rainwater residue. At the same time, it can also reduce the adhesion of dust to the cover plate 2 and improve self-cleaning efficiency.

[0035] The third embodiment differs from the first embodiment in that:

[0036] The outer wall of the curved surface 101 is evenly spaced with multiple supporting ribs 4 for auxiliary support of the air membrane. The end of the supporting rib 4 away from the curved surface 101 is attached to the inner side of the air membrane.

[0037] Multiple supporting ribs 4, evenly spaced on the outer wall of the curved surface 101, are used to provide auxiliary support for the air membrane. When the air membrane is inflated or subjected to external loads, the supporting ribs 4 can transfer the local pressure on the air membrane to the curved surface 101, and then distribute it to the entire support member 1 through the curved surface 101, so as to prevent the air membrane from sinking or tearing due to excessive local stress. At the same time, the evenly spaced distribution can ensure that the air membrane is subjected to balanced stress in each area, further improving the structural stability of the air membrane top cover.

[0038] When the blower 3 is installed on the bottom surface of the inner cavity 201, the sealing gasket at the connection between the two is tightly fitted between the outer shell of the blower 3 and the bottom surface of the inner cavity 201, forming a sealed barrier. During the operation of the blower 3, the sealing gasket can effectively prevent the airflow in the inner cavity 201 from leaking from the connection, ensuring that all the airflow is discharged through the connecting pipe 202 to achieve the self-cleaning function. At the same time, it can also prevent rainwater, dust and other impurities from entering the inner cavity 201 or the interior of the air membrane from the connection, avoiding impurities from affecting the normal operation of the blower 3 or polluting the internal environment of the air membrane, extending the service life of the equipment and ensuring the hygiene of the air membrane.

[0039] The curvature of the supporting rib 4 matches the curvature of the inner side of the air membrane, so that the end of the supporting rib 4 away from the curved surface 101 is fully in contact with the inner side of the air membrane. The cross-section of the supporting rib 4 is circular or elliptical. The curved supporting rib 4 has a larger contact area with the air membrane and the supporting force is more dispersed, which can avoid the edge of the rib from causing local compression damage to the air membrane. At the same time, the fitted curved structure can also allow the supporting rib 4 to more accurately follow the shape of the air membrane to provide support. When the air membrane undergoes slight deformation due to temperature changes or airflow fluctuations, the supporting rib 4 can always maintain effective contact with the air membrane to ensure that the auxiliary support effect is not weakened.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
