[0027] Embodiment
[0028] Refer to Figure 1 As shown, an independent air film built-in air duct provided in this embodiment makes the air duct inside the air film, avoiding interference between the air duct and the cable on the surface of the air film.
[0029] Specifically, refer to Figure 2 As shown, an independent air film built-in air duct provided in this embodiment includes two relatively separated air film materials 1, an independent air duct and a tension cable 2. The independent air duct is respectively connected to the two air film materials 1 and is located inside the air film. The independent air duct extends along the long span or short span of the air film, forming an independent air duct inside the air film. An exhaust port 5 communicating with the inside of the air film is provided on the independent air duct, and gas exchange is carried out with the inside of the air film through this exhaust port. The independent air duct is of an independent structure, which is convenient for overall prefabrication and on-site assembly.
[0030] Specifically, the tension cable 2 is placed inside the independent air duct, and both ends of the tension cable 2 are respectively connected to the lower structures 6 on both sides of the air film. The tension cable 2 supports the independent air duct in a direction away from the air film material 1, so that a receiving space is formed inside the independent air duct. The independent air duct is tensioned by the tension cable 2, so that the independent air duct can be formed and the independent air duct is tightened to keep it stable. Further, placing the tension cable 2 inside the independent air duct to tension the independent air duct not only does not require additional fixing measures to relatively fix the independent air duct and the tension cable 2, but also the independent air duct itself extends along the long span or short span direction of the air film, and the length of its contour is large. The independent air duct may deform along its length direction during use, and the tension cable 2 is in full contact with the independent air duct along its length direction, so that the tension cable 2 can deform with the deformation of the independent air duct, resulting in better force application effect.
[0031] An independent air film built-in air duct provided in this embodiment places the air duct inside the air film, avoiding interference between the air duct and the cable, adopting an independent air duct structure, which is convenient for overall prefabrication and on-site installation, and placing the tension cable 2 inside the independent air duct for tensioning, so that the tension cable 2 can deform with the deformation of the air duct, and the force application effect is better.
[0032] Specifically, with continued reference to Figure 2 As shown, the independent air duct includes a first air duct film material 3 and a second air duct film material 4. The two edges of the second air duct film material 4 are respectively connected to the two edges of an air duct film material, thereby enclosing a spatial structure. The tension cable 2 is located between the first air duct film material 3 and the second air duct film material 4. The second air duct film material 4 is supported by tensioning the second air duct film material 4 in a direction away from the air film material 1 by the tension cable 2. In fact, the tension cable 2 is located at the middle position of the second air duct film material 4. After the second air duct film material 4 is supported by tensioning the second air duct film material 4 by the tension cable 2, the cross-section of the independent air duct forms a triangular structure, and the exhaust holes are arranged on the second air duct film material 4, that is, the exhaust holes are located on the two side surfaces of the triangular structure.
[0033] Specifically, after the air film material 1, the first air duct film material 3 and the second air duct film material 4 are sequentially attached, the installation bolts 7 pass through the three of them in sequence to lock the three of them. The air film material 1 and the independent air duct are relatively fixed during the installation process, and the installation process is simple and convenient. It should be noted that in Figure 2 , the separation state between the air film material 1 and the first air duct film material 3 is to better distinguish the two, but in fact, the air film material 1 and the first air duct film material 3 are in a attached state after the assembly is completed.
[0034] Specifically, it further includes a first clamping plate 8 and a second clamping plate 9. The first clamping plate 8 is located outside the air film material 1, and the second clamping plate 9 is located inside the second air duct film material 4. The installation bolt 7 passes through the first clamping plate 8 and the second clamping plate 9, and the air film material 1, the first air duct film material 3, and the second air duct film material 4 are clamped by the first clamping plate 8 and the second clamping plate 9. In order to prevent the film material from being torn due to the shear force generated by the installation bolt 7, rope edges are respectively provided at the edges of the air film material 1, the first air duct film material 3, and the second air duct film material 4. The diameter of the rope edge is greater than the thickness of the film material, so that the rope edge abuts against the first clamping plate 8 and the second clamping plate 9, and the rope edge bears the tension to prevent the film material from being torn.
[0035] Specifically, with reference to Figure 3 As shown, the lower structure 6 is a concrete pouring structure, and a pre-embedded part 10 is provided in the lower structure 6 to connect the tension cable 2 to the pre-embedded part 10, thereby fixing the tension cable 2.
[0036] Specifically, with continued reference to Figure 2 As shown, since a joint is formed at the connection position between the air film material 1 and the independent air duct, a rainproof curtain 11 is provided on the outside of the air film to prevent rainwater from penetrating. One side of the rainproof curtain 11 is connected to the air film material 1, and the other side is connected to the independent air duct, specifically connected to the first air duct film material 3. The rainproof curtain 11 surrounds the joint to prevent rainwater from penetrating.
[0037] Specifically, the rainproof curtain 11 can be connected in such a way that one side is welded to the air film material 1, and the other side is bonded to the first air duct material 3 through a magic tape 12. The rainproof curtain 11 can be welded to the air film material 1 during the prefabrication process of the air film material 1, and a magic tape male buckle is sewn on the rainproof curtain 11, and a magic tape female buckle is sewn on the first air duct material 3. During the on-site assembly process, after connecting the air film material 1 and the independent air duct with the installation bolts 7, the rainproof curtain 11 is bonded to the first air duct air film by using the magic tape 12.
[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope recorded in this specification.
[0039] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
