[0062] The air film membrane connecting device and the air film building according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0063] Reference Figures 1 to 7 As shown, the air film membrane connection device provided according to an embodiment of the present invention includes a first membrane 10, a second membrane 20 and a plurality of ferrules 30.

[0064] Specifically, the splicing edge of the first diaphragm 10 has a first stop edge 101, and the first stop edge 101 extends along the splicing edge of the first diaphragm 10. The splicing edge of the second diaphragm 20 has a second stop edge 201, and the second stop edge 201 extends along the splicing edge of the second diaphragm 20, and a splicing seam is formed between the second stop edge 201 and the first stop edge 101.

[0065] It can be understood that the first diaphragm 10 and the second diaphragm 20 are two diaphragms that need to be spliced, the splicing edge of the first diaphragm 10 and the splicing edge of the second diaphragm 20 are close to each other, and the splicing edge of the first diaphragm 10 has a first stop edge 101, and the splicing edge of the second diaphragm 20 has a second stop edge 201. There is a gap between the first stop edge 101 and the second stop edge 201, and the gap is the splicing seam. In addition, the diameter or thickness of the first stop edge 101 is greater than the thickness of the first diaphragm 10, and the diameter or thickness of the second stop edge 201 is greater than the thickness of the second diaphragm 20.

[0066] Multiple ferrules 30 are located in the joint seam and arranged in sequence along the joint seam, each ferrule 30 has a first hole H301 and a second hole H302, the side wall of the first hole H301 has a first opening H3011, the side wall of the second hole H302 is provided with a second opening H3021, and the second opening H3021 is opposite to the first opening H3011.

[0067] The first stop edge 101 passes through the first clamping holes H301 of the plurality of the ferrules 30 in sequence, and the width of the first opening H3011 is smaller than the diameter of the first stop edge 101, so as to limit the first stop edge 101 within the first clamping hole H301, and the second stop edge 201 passes through the second clamping holes H302 of the plurality of the ferrules 30 in sequence, and the width of the second opening H3021 is smaller than the diameter of the second stop edge 201, so as to limit the second stop edge 201 within the second clamping hole H302.

[0068] The ferrule 30 can be made of metal material, such as aluminum alloy, to ensure that the ferrule 30 has relatively large strength and can withstand the tension between the first air film and the second air film.

[0069] That is to say, two clamping holes are arranged on the clamping sleeve 30, namely the first clamping hole H301 and the second clamping hole H302. The first clamping hole H301 is adjacent to the splicing edge of the first diaphragm 10, and the second clamping hole H302 is adjacent to the splicing edge of the second diaphragm 20. During the construction process, the first clamping hole H301 of the clamping sleeve 30 is inserted into the first stop edge 101 on the first diaphragm 10, and the second clamping hole H302 of the clamping sleeve 30 is inserted into the second stop edge 201 on the second diaphragm 20. In this way, a plurality of clamping sleeves 30 can be connected between the splicing edge of the first diaphragm 10 and the splicing edge of the second diaphragm 20. The width of the opening H3011 is smaller than the diameter of the first stop edge 101, and the width of the second opening H3021 on the ferrule 30 is smaller than the diameter of the second stop edge 201. Therefore, when the first stop edge 101 passes through the first clamping hole H301 of the ferrule 30, and the second stop edge 201 passes through the second clamping hole H302, the first stop edge 101 will not fall out of the first opening H3011, and the second stop edge 201 will not fall out of the second opening H3021, thereby enabling the first diaphragm 10 and the second diaphragm 20 to be connected together through multiple ferrules 30 and to withstand the tension between the first diaphragm 10 and the second diaphragm 20.

[0070] According to the air film diaphragm connection device provided in the embodiment of the present invention, the first stop edge 101 of the first diaphragm 10 is directly passed through the first clamping holes H301 of multiple clamping sleeves 30 in sequence, and the second stop edge 201 of the second diaphragm 20 is passed through the second clamping holes H302 of multiple clamping sleeves 30 in sequence, so as to realize the connection between the first diaphragm 10 and the second diaphragm 20. It has a simple structure, convenient construction and high efficiency.

[0071] Reference Figures 1 to 7As shown, in some embodiments of the present invention, a waterproof drape 40 is further included, which covers the outside of the plurality of sleeves 30 and extends along the joint seam, one side of the waterproof drape 40 is heat-sealed with the first membrane 10, and the other side of the waterproof drape 40 is heat-sealed with the second membrane 20.

[0072] Since a plurality of ferrules 30 are located in the joint seam, there is a gap between two adjacent ferrules 30. Therefore, in this embodiment, a waterproof curtain 40 is arranged outside the joint seam and the ferrule 30. One side of the waterproof curtain 40 is heat-sealed with the first membrane 10, and the other side of the waterproof curtain 40 is heat-sealed with the second membrane 20. In this way, the joint seam and the ferrule 30 are completely sealed inside by the waterproof curtain 40. In this way, water can be prevented from entering the interior of the air film building from the gap between the joint seam and the ferrule 30, achieving a good waterproof effect. In addition, it can also prevent gas leakage inside the air film building and improve the overall air tightness of the air film.

[0073] Reference Figure 6 to Figure 7 As shown, in some embodiments of the present invention, a plurality of soft rubber gaskets 60 are further included, and one soft rubber gasket 60 is provided between two adjacent ferrules 30, so as to fill the gap between the two adjacent ferrules 30 through the soft rubber gasket. The soft rubber gasket 60 can be made of rubber material or silicone material, etc., to achieve a good sealing and filling effect.

[0074] Since the ferrule 30 is connected to the first diaphragm 10 and the second diaphragm 20, it needs to bear the tension of the first diaphragm 10 and the second diaphragm 20. Therefore, the ferrule 30 is generally made of a hard material with high strength, such as aluminum alloy. Moreover, the surface of the air film building is not all flat. Therefore, it is inevitable that there is a certain gap between two adjacent ferrules 30. These gaps may cause the air tightness and waterproof effect to be reduced. In order to further improve the air tightness and waterproof effect, in this embodiment, a soft rubber gasket 60 is set between any two adjacent ferrules 30, and the soft rubber gasket 60 is used to seal and fill the gap between the two ferrules 30. In this way, the air tightness and waterproof effect of the air film can be further improved.

[0075] Reference Figure 7 As shown, in one embodiment of the present invention, each of the soft rubber gaskets 60 has a third clamping hole H601 and a fourth clamping hole H602, the side wall of the third clamping hole H601 has a third opening H6011, the side wall of the fourth clamping hole H602 is provided with a fourth opening H6021, and the third opening H6011 is opposite to the fourth opening H6021.

[0076] The first stopper passes through the third clamping hole H601, the second stopper edge 201 passes through the fourth clamping hole H602, the width of the third opening H6011 is smaller than the diameter of the first stopper edge 101, and the width of the fourth opening H6021 is smaller than the diameter of the second stopper edge 201, so that the soft rubber gasket 60 is fixed in the splicing seam.

[0077] That is to say, the soft rubber gasket 60 adopts a structure similar to that of the ferrule 30. During construction, the first stop edge 101 of the first diaphragm 10 and the second stop edge 201 on the second diaphragm 20 respectively pass through the third clamping hole H601 and the fourth clamping hole H602 on the soft rubber gasket 60. In this way, by utilizing the stop cooperation between the first stop edge 101 and the third clamping hole H601, and the stop cooperation between the second stop edge 201 and the fourth clamping hole H602, the soft rubber gasket 60 can be reliably clamped between two adjacent ferrules 30, and the soft rubber gasket 60 and the two adjacent ferrules 30 can maintain fit, and the sealing effect is better.

[0078] Reference Figures 4 to 7 As shown, in one embodiment of the present invention, it also includes a tightening rope 50, and the tightening rope 50 tightens the multiple ferrules 30 along the direction of the splicing seam, so that any two adjacent ferrules 30 clamp the soft rubber gasket 60 therebetween to form a seal.

[0079] In this embodiment, a tightening rope 50 is used to tighten multiple ferrules 30 and soft rubber gaskets 60 along the direction of the splicing seam. Since the multiple ferrules 30 are arranged in sequence along the direction of the splicing seam, and each soft rubber gasket 60 is located between each ferrule 30, the tightening rope 50 can make the ferrule 30 and the soft rubber gasket 60 clamp and fit each other, thereby forming a better sealing effect.

[0080] In one embodiment of the present invention, a first wire passing hole is provided on the ferrule 30, a second wire passing hole is provided on the soft rubber gasket 60, and the tightening rope 50 passes through each of the first wire passing hole and the second wire passing hole.

[0081] That is to say, when the tightening rope 50 passes through the first wire hole on the ferrule 30 and the second wire hole on the soft rubber gasket 60, it can be ensured that each ferrule 30 and the soft rubber gasket 60 are connected in series by the tightening rope 50, and the assembly relationship is more reliable. Moreover, when the tightening rope 50 is tightened, it can be ensured that each ferrule 30 and each soft rubber gasket 60 fits more tightly and reliably.

[0082] Advantageously, there are two first wire passing holes and two second wire passing holes, and there are two tightening ropes 50. One of the two tightening ropes 50 passes through one of the first wire passing holes on the ferrule 30 and one of the second wire passing holes of the soft rubber gasket 60, and the other of the two tightening ropes 50 passes through the other first wire passing hole on the ferrule 30 and the other second wire passing hole of the soft rubber gasket 60. In this way, by tightening multiple ferrules 30 and soft rubber gaskets 60 with two tightening ropes 50, it can be ensured that the extrusion force between the ferrule 30 and the soft rubber gasket 60 is more evenly dispersed, thereby improving the fit between the ferrule 30 and the soft rubber gasket 60.

[0083] More advantageously, the tightening rope 50 may be an elastic rope, which is elastic and can provide a continuous contraction force by utilizing the elastic effect, so that the sleeve 30 and the soft rubber gasket 60 maintain a tight fit.

[0084] In one embodiment of the present invention, the waterproof drape 40 includes a first drape 401 and a second drape 402, the upper side edge of the first drape 401 is heat-sealed and connected to the first membrane 10, the lower side edge of the second drape 402 is heat-sealed and connected to the second membrane 20, the upper side edge of the second drape 402 is connected to the lower side edge of the first drape 401 via Velcro 41, and the first drape 401 is located above the second drape 402.

[0085] That is, the first drape 401 is heat-sealed to the first membrane 10, the second drape 402 is heat-sealed to the second drape 402, and the first drape 401 and the second drape 402 are connected by the Velcro 41. During the production and processing of the first membrane 10 and the second drape 402, the first drape 401 and the second drape 402 can be directly heat-sealed to the first membrane 10 and the second membrane 20, respectively. In this way, in use, after the first membrane 10 and the second membrane 20 are connected by the card sleeve, the first drape 401 and the second drape 402 can be connected together by the Velcro 41, and the construction is more convenient. In addition, the first drape 401 and the second drape 402 can be opened to facilitate the inspection of the splicing seam.

[0086] Reference Figures 1 to 7As shown, in one embodiment of the present invention, the splicing edge of the first film sheet 10 wraps a first edge cord 11 to form the first stop edge 101, and the splicing edge of the second film sheet 20 wraps a second edge cord 21 to form the second stop edge 201. Exemplarily, the splicing edge of the first film sheet 10 is folded and wrapped around the first edge cord 11, and then heat-sealed on the first film sheet 10, and the splicing edge of the second film sheet 20 is folded and wrapped around the second edge cord 21, and then heat-sealed on the second film sheet 20, thereby forming the above-mentioned first stop edge 101 and the second stop edge 201. The first stop edge 101 and the second stop edge 201 of the above-mentioned structure have high structural strength and are not easy to be separated when matched with the first clamping hole H301 and the second clamping hole H302.

[0087] The air-film building according to the embodiment of the present invention has the air-film membrane connecting device as described above.

[0088] It can be understood that the air-supported building in the embodiment of the present invention also includes a building foundation, a steel cable net, etc. The first membrane 10 and the second membrane 20 are spliced ​​to form an air membrane. The lower edge of the air membrane is fixed and sealed on the building foundation, and the steel cable net covers the outer surface of the air membrane. The specific implementation method is a known technology in the field and will not be described in detail here.

[0089] According to the air-film building provided in the embodiment of the present invention, the first stop edge 101 of the first diaphragm 10 is directly passed through the first clamping holes H301 of multiple clamping sleeves 30 in sequence, and the second stop edge 201 of the second diaphragm 20 is passed through the second clamping holes H302 of multiple clamping sleeves 30 in sequence, so as to realize the connection between the first diaphragm 10 and the second diaphragm 20. It has a simple structure, convenient construction and high efficiency.
