[0034] Example

[0035] Reference Figure 1 As shown, this embodiment provides an air film 3 with a built-in air duct, which specifically includes an air duct membrane material 1 and a tension cable 2. Figure 2 As shown, the two sides of the air duct membrane material 1 are respectively connected to the inner wall of the air membrane 3, so that the air duct membrane material 1 and the air membrane 3 surround a storage space extending in one direction. Specifically, the storage space is located in the internal space of the air membrane 3, and the extension direction of the storage space can be the short span direction of the air membrane 3 or the long span direction of the air membrane 3. In this embodiment, the extension direction of the storage space is preferably the short span direction of the air membrane 3, so that the storage space forms an arc shape along the short span direction of the air membrane 3. Figure 2 As shown, the air duct membrane material 1 is provided with an exhaust hole 4 connecting the accommodating space with the inner space of the air membrane 3, and gas exchange is performed through the exhaust hole 4.

[0036] Continue to refer to Figure 1As shown, the two ends of the tensioning cable 2 are respectively connected to the foundations on both sides of the air film 3; the tensioning cable 2 extends along the extension direction of the accommodation space and is connected to the air duct membrane material 1. When the air film 3 is inflated, the tensioning cable 2 tensions the air duct membrane material 1 downward, so that the accommodation space becomes a three-dimensional film-in-film air duct 5. When the air film 3 is prepared, the air duct membrane material 1 can be connected to the inner wall of the air film 3 at the same time, and before the air film 3 is inflated, the tensioning cable 2 is connected to the foundation, and the tensioning cable 2 tensions the air duct membrane material 1 to form the film-in-film air duct 5.

[0037] The air film 3 provided in this embodiment has a built-in air duct, and the air duct is installed on the inner wall of the film material, thereby avoiding interference between the air duct and the net cable, ensuring the reliability of the air duct structure; and avoiding the formation of a raised bulge on the top of the air film 3, thereby avoiding large-scale snow accumulation on the top of the film caused by the bulge. By connecting the two sides of the air duct membrane material 1 with the inner wall of the air film 3, and tensioning the air duct membrane material 1 with the tensioning cable 2 to form the air duct 5 inside the membrane, the air duct can be installed simultaneously when the air film 3 is processed in the factory, reducing the complexity of the air duct installation and avoiding the safety hazards of high-altitude operations.

[0038] Specifically, the air duct membrane material 1 can be connected to the inner wall of the air membrane 3 through different connection structures. In this embodiment, two connection structures are used as examples for description.

[0039] Reference Figure 3 As shown, the air duct membrane material 1 is connected to the inner wall of the air membrane 3 through the first connection structure 6. The first connection structure 6 includes a first folded edge 61 formed by folding along the side of the air duct membrane material 1, and a first auxiliary membrane material 62. The first folded edge 61 is welded to the inner wall of the air membrane 3, and the first auxiliary membrane material 62 includes a first part 63 and a second part 64, wherein the first part 63 is welded to the inner wall of the air membrane 3, and the second part 64 is welded to the air duct membrane material 1. Three welds are formed between the air membrane 3, the air duct membrane material 1, and the first auxiliary membrane material 62, so that they form a T-shaped structure, which increases the connection strength between the air duct membrane material 1 and the air membrane 3, thereby ensuring the reliability of the formed built-in air duct, and the welding process can be directly completed in the factory synchronously with the preparation process of the air membrane 3.

[0040] Reference Figure 4As shown, the air duct membrane material 1 is connected to the inner wall of the air membrane 3 through the second connection structure 7. The second connection structure 7 includes a second folded edge 71 formed by folding along the side of the air duct membrane material 1, a bolt 72, a nut 73 and two pressing plates 74. The second folded edge 71 is in contact with the inner wall of the air membrane 3, one pressing plate 74 is pressed on the outside of the air membrane 3, and one pressing plate 74 is pressed on the inside of the second folded edge 71, and the two pressing plates 74 clamp the air membrane 3 and the second folded edge 71. The bolt 72 passes through the two pressing plates 74 and is connected to the nut 73 to press the second folded edge 71 and the air membrane 3. An anti-slip portion 75 is connected to the edge of the second folded edge 71, and the anti-slip portion 75 extends along the edge of the second folded edge 71, and the anti-slip portion 75 is cylindrical, and its diameter is greater than the thickness of the second folded edge 71. The anti-slip portion 75 and the clamping plate resist each other to bear the tensile force of the air duct membrane material 1, thereby ensuring the reliability of the connection between the air duct membrane material 1 and the air membrane 3. In order to reduce the number of holes in the air film 3 and consumables, the second connection structure 7 can be set at the film seam of the air film 3, that is, the bolt 72 also passes through the two pieces of air film 76 that are attached to each other, and the bolt 72 simultaneously locks the two pieces of air film 76 and the second folded edge 71. In order to prevent leakage on the surface of the air film 3, a protective film 77 is welded on the outside of the air film 3, and the protective film 77 covers the second connection structure 7.

[0041] It should be noted that in other embodiments, both sides of the air duct membrane material 1 can use the first connection structure 6 to connect with the air membrane 3, or can use the second connection structure 7 to connect with the air membrane 3. In this embodiment, the air duct membrane material 1 uses the first connection structure 6 to connect with the air membrane 3 on one side, and the second connection structure 7 to connect with the air membrane 3 on the other side. This method is more economical and practical.

[0042] Specifically, in this embodiment, a tensioning cable 2 is selected to connect with the air duct membrane material 1, and the air duct membrane material 1 is tensioned to a triangular cross section, and the exhaust holes 4 are arranged on two sides of the triangular shape of the air duct membrane material 1. In other embodiments, different numbers of tensioning cables 2 may be selected to tension the air duct membrane material 1, so that the air duct membrane material 1 is tensioned to a corresponding polygonal cross section.

[0043] Specifically, refer to Figure 5 As shown, a cable sleeve 8 is connected to the top of the air duct 5 in the membrane, and the cable sleeve 8 includes a second auxiliary membrane material 81, and the two sides of the second auxiliary membrane material 81 are respectively welded to the two sides of the air duct membrane material 1, and a channel 82 for accommodating the tensioning cable 2 to pass through is formed in the middle of the second auxiliary membrane material 81. A plurality of cable sleeves 8 arranged along the extension direction of the accommodating space are connected to the air duct membrane material 1, and the tensioning cable 2 passes through each cable sleeve 8 in turn, so as to evenly tension the air duct membrane material 1.

[0044] Specifically, continue to refer to Figure 1As shown, the foundation includes an air film retaining wall 9 and a material retaining notch 10 connected to the air film retaining wall 9, and the tensioning cable 2 is connected to the material retaining notch 10; specifically, the air film retaining wall 9 and the material retaining notch 10 can be cast by concrete, and embedded parts are provided on the side of the material retaining notch 10, and the tensioning cable 2 is connected to the embedded parts and thus connected to the material retaining notch 10. In other embodiments, the two ends of the tensioning cable 2 can also be fixed to the ground or other connecting structures. The top of the air duct membrane material 1 extends to connect with the material retaining notch 10, thereby forming a complete air duct 5 inside the ground membrane, and an exhaust valve can be provided on the air film retaining wall 9, and the material retaining notch 10 can be used as a communication channel between the air duct 5 inside the membrane and the outside.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
