Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane structures, and more specifically, to an air-supported membrane ring beam with anti-seepage function. Background Technology

[0002] In modern construction engineering, air-supported membrane structures are widely used due to their rapid construction speed, low cost, and excellent sealing performance. Air-supported membrane structures are typically made of high-strength, flexible membrane materials, forming a stable spatial structure by inflating the interior. This type of architecture is particularly suitable for temporary large-scale event venues, stadiums, storage spaces, and similar applications.

[0003] However, a major challenge of air-supported membrane structures is ensuring their impermeability. Because air-supported membranes are prone to leakage at joints and edges, especially at their installation and fixing points with ring beams, special measures are needed to prevent air leakage and moisture penetration. Existing fixing methods often have insufficient impermeability. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes an air-supported membrane ring beam with anti-seepage function.

[0005] An air-supported membrane ring beam with seepage prevention function is disclosed. The ring beam is made of reinforced concrete and has an installation groove. The lower part of the air-supported membrane is installed in the installation groove. The upper part of the ring beam is provided with evenly distributed pre-embedded anchor bolts. Anchor steel cables are provided on the air-supported membrane and are tightly connected to the pre-embedded anchor bolts. A seepage prevention sealing plate is also provided on the outer side of the bottom of the air-supported membrane. The seepage prevention sealing plate is an integrated structure composed of a horizontal plate, a vertical plate, and a pressing plate. The horizontal plate is located at the lower end of the front side of the vertical plate and is pressed against the ring beam on one side of the installation groove. The pressing plate is located at the rear side of the vertical plate and has an arc-shaped rear side. An injection channel is provided inside the pressing plate. The upper opening of the injection channel is located at the top of the pressing plate, and the lower opening of the injection channel is located on the rear side. Seepage prevention and sealing coating is injected into the injection channel.

[0006] Preferably, the horizontal plate is provided with a pin hole, and the ring beam on one side of the mounting groove is provided with a slot that is directly opposite the pin hole. The anti-seepage sealing plate can be fixed by passing a pin through the pin hole and nailing it into the slot.

[0007] Preferably, the lower part of the air film is provided with a seepage-proof bonding surface, and the lower opening of the injection channel is attached to the middle part of the outer side of the seepage-proof bonding surface.

[0008] Preferably, the upper end of the upright plate is higher than the upper end of the clamping plate.

[0009] Beneficial effects:

[0010] 1. This device is equipped with a seepage-proof sealing plate at the junction of the installation trench and the air membrane. By injecting seepage-proof sealing coating, it effectively prevents water from seeping in from the connection between the air membrane and the ring beam.

[0011] 2. The anti-seepage sealing plate, fixed with pins, simplifies the installation process and reduces construction difficulty;

[0012] 3. The integrated waterproof sealing plate design reduces material usage and lowers costs;

[0013] 4. A ring of anti-seepage bonding surface is provided at the bottom of the air film. The lower opening of the injection channel is attached to the middle of the outer side of the anti-seepage bonding surface, so that the anti-seepage sealing coating can match the anti-seepage bonding surface to improve the anti-seepage effect.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] In this embodiment, as Figures 1-4 The diagram shows an air-supported membrane 2 ring beam with seepage prevention function. The ring beam 1 is made of reinforced concrete and has an installation groove 4 for the installation of the lower part of the air-supported membrane 2. The upper part of the ring beam 1 is provided with evenly distributed pre-embedded anchor bolts 3. The anchoring steel cables on the air-supported membrane 2 are tightly connected to the pre-embedded anchor bolts 3 to enhance the connection stability between the air-supported membrane 2 and the ring beam 1.

[0020] After the air-supported membrane 2 is installed, there will be a gap 6 between the installation groove 4 and the upper part of the outer side of the air-supported membrane 2. Therefore, a seepage-proof sealing plate 5 is set on the outer side of the bottom of the air-supported membrane 2. The seepage-proof sealing plate 5 is an integrated structure composed of a horizontal plate 51, a vertical plate 52, and a pressing plate 53. The horizontal plate 51 is located at the lower end of the front side of the vertical plate 52 and is pressed against the ring beam 1 on one side of the installation groove 4. The pressing plate 53 is located on the rear side of the vertical plate 52. Its front side is straight and fits tightly against the side wall of the installation groove 4. Its rear side 54 is arc-shaped and has an injection channel 57 inside. The upper opening 55 of the injection channel 57 is located at the top of the pressing plate 53, and the lower opening 56 is located on the rear side 54. The channel is filled with seepage-proof sealing coating. The seepage-proof sealing coating is initially fluid and becomes solid after solidification. Waterproof coating can be preferred.

[0021] To ensure the stability of the seepage-proof sealing plate 5, a pin hole 58 is provided on the horizontal plate 51, and a slot 59 is provided on the ring beam 1 that is directly opposite the pin hole 58. The seepage-proof sealing plate 5 is fixed by passing a pin 8 through the pin hole 58 and nailing it into the slot 59.

[0022] The lower part of the air membrane 2 is provided with a ring of anti-seepage bonding surface 7. The lower opening 56 of the injection channel 57 is attached to the middle of the outer side of the anti-seepage bonding surface 7 to improve the anti-seepage effect. In actual use, the waterproof coating can be pre-coated on the lower part of the air membrane 2. After it cools down, it becomes the anti-seepage bonding surface 7. In this way, the waterproof coating injected later can better bond with the anti-seepage bonding surface 7.

[0023] The upper end of the upright plate 52 is higher than the upper end of the pressing plate 53. The upright plate 52 is higher than the pressing plate 53, which can form a groove 9 on the upper end of the pressing plate 53. This groove 9 can also be filled with anti-seepage sealant to improve the sealing and anti-seepage effect.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
