Description

Technical Field

[0001] This application relates to the field of air membranes, and particularly to an air-ribbed membrane structure with a stable structure. Background Art

[0002] The air-ribbed membrane structure is a lightweight structure supported by inflation, mainly composed of high-strength thin film materials. By inflating the inside to form a ribbed support structure, it can cover large-span spaces without internal columns. Existing air-ribbed membrane structures are often fixed by tying heavy objects such as sandbags or pull rings to the rib feet at both ends through ground anchors or placing objects inside the rib feet. However, such fixing methods still have technical deficiencies such as poor stability and poor surface strength of the air-ribbed membrane. Utility Model Content

[0003] In view of the above deficiencies in the prior art, this application provides an air-ribbed membrane structure with a stable structure to solve at least one of the above technical problems. The specific structure is as follows:

[0004] An air-ribbed membrane structure with a stable structure includes an air-ribbed membrane, a first limiting member, and a second limiting member. Among them, there is an inflation space inside the air-ribbed membrane, and a strip-shaped opening and closing structure is provided on the rib feet of the air-ribbed membrane. The opening and closing structure is used to make the air-ribbed membrane communicate or be sealed with respect to the outside.

[0005] The first limiting member is located on one side of the length direction of the opening and closing structure on the outer surface of the air-ribbed membrane, and the second limiting member is located on the other side of the length direction of the opening and closing structure on the outer surface of the air-ribbed membrane; there is at least one intersection point between the projections of the first limiting member and the second limiting member in the connected state on the outer surface of the air-ribbed membrane and the opening and closing structure. The first limiting member and the second limiting member are used for detachably connecting to each other to form a stable structure that covers part of the opening and closing structure and stabilizes the opening and closing structure.

[0006] In practical applications, the strip-shaped opening and closing structure can extend in different directions. In a specific embodiment, the opening and closing structure can be arranged along the extending direction of the perimeter of the cross-section of the air-ribbed membrane in the radial direction, or along the direction perpendicular to the cross-section of the air-ribbed membrane in the radial direction, or can be obliquely arranged on the surface of the air-ribbed membrane.

[0007] In practical applications, there can be multiple first limiting members and the second limiting members respectively. Each first limiting member arranged on one side of the length direction of the opening and closing structure can be detachably connected to any second limiting member arranged on the other side of the length direction of the opening and closing structure.

[0008] In some specific embodiments, the first limiting member and the second limiting member include an elastic band. By providing the elastic band, the connection between the first limiting member and the second limiting member can be made more elastic, which can meet the stability requirements of the air rib film under different inflation intensity states.

[0009] In some specific embodiments, one of the first limiting member and the second limiting member includes a first connecting band, and the other includes a second connecting band. One end of the first connecting band is connected to one side in the length direction of the opening and closing structure, and the other end of the first connecting band is a free end; one end of the second connecting band is connected to the other side in the length direction of the opening and closing structure, and the other end of the second connecting band is a free end. The free end of the first connecting band is used for detachable connection with the free end of the second connecting band.

[0010] In some specific embodiments, a length adjustment buckle is provided at a position close to the free end of the first connecting band. The free end of the second connecting band is used for detachable connection with the free end of the first connecting band through the length adjustment buckle, and the overall length after the connection of the first connecting band and the second connecting band is adjusted through the length adjustment buckle.

[0011] In practical applications, by adjusting the overall length after the connection of the first connecting band and the second connecting band, the overall length can be made less than or equal to the length of the air rib film between the connection point of the first connecting band on the air rib film surface and the connection point of the second connecting band on the air rib film, so that the stable structure formed between the first limiting member and the second limiting member can form a better fit with the air rib film, the contact area between the stable structure and the air rib film surface is larger, and more stress points can be provided.

[0012] In some specific embodiments, one of the first limiting member and the second limiting member is provided with an elastic buckle near one end close to the opening and closing structure; the other of the first limiting member and the second limiting member is provided with an elastic buckle receiving member for cooperating with the elastic buckle near one end close to the opening and closing structure.

[0013] In practical applications, the elastic buckle is used to be placed into the elastic buckle receiving member to make the detachable connection between the first limiting member and the second limiting member.

[0014] In some specific embodiments, one of the first limiting member and the second limiting member is provided with a buckle and a snap pin near one end close to the opening and closing structure; a plurality of positioning holes are distributed on the other of the first limiting member and the second limiting member.

[0015] The buckle is used to pass through the second limiting member; the snap pin is used to pass through different positioning holes on the second limiting member to engage with the buckle to adjust the connection tightness between the first limiting member and the second limiting member.

[0016] In some specific embodiments, one of the first limiting member and the second limiting member is provided with a connection detection member at one end close to the opening and closing structure, and the connection detection member is used to detect whether there is a connection between the first limiting member and the second limiting member.

[0017] In some specific embodiments, it further includes a covering curtain, a first adhesive member, and a second adhesive member; one end of the covering curtain is connected to a position on one side in the length direction of the opening and closing structure on the outer surface of the air rib membrane. The first adhesive member is arranged on the side of the other end of the covering curtain facing the air rib membrane; the second adhesive member is arranged at a position on the outer surface of the air rib membrane close to the other side of the opening and closing structure; the first adhesive member is used for detachable connection with the second adhesive member to cover the opening and closing structure with the covering curtain.

[0018] In practical applications, by completely covering the opening and closing structure with the covering curtain, the opening and closing structure can be further isolated from the outside when not opened, providing protection for the opening and closing structure, effectively reducing the external wear suffered by the opening and closing structure, and enhancing its strength.

[0019] In some specific embodiments, the first adhesive member and the second adhesive member are a kind of cooperating magic tape structure, or snap structure, or zipper structure.

[0020] In some specific embodiments, the stable structure formed by the first limiting member and the second limiting member is symmetrically arranged with respect to the midline in the length direction of the opening and closing structure.

[0021] In some specific embodiments, the opening and closing structure includes a zipper structure. In practical applications, this zipper structure is a high-strength, high-hermeticity, and waterproof zipper structure. By setting the zipper structure, the user can more conveniently open and close the opening and closing structure. In a specific embodiment, the zipper structure is arranged along the extending direction of the perimeter of the cross-section of the air rib membrane in the radial direction.

[0022] Beneficial effects: The present application provides an air rib type membrane structure with a stable structure. By arranging a strip-shaped opening and closing structure on the surface of the air rib membrane, and respectively arranging a first limiting member and a second limiting member with detachable connection on both sides in the length direction of the opening and closing structure, a stable structure that covers part of the opening and closing structure and stabilizes the opening and closing structure can be formed. Further, various connection relationships and connection structures between the first limiting member and the second limiting member are set, making the stable structure flexible and adjustable, and more secure, capable of multi-layer stabilizing and limiting the surface of the air rib membrane, effectively improving the surface strength of the air rib membrane, and improving the stability of the rib feet of the air rib type membrane structure.

[0040] Embodiment

[0041] The present application provides a gas-ribbed membrane structure with a stable structure, and the specific solution is as follows:

[0042] A gas-ribbed membrane structure with a stable structure 3 includes a gas-ribbed membrane 1, a first limiting member 31, and a second limiting member 32. Among them, there is an inflation space inside the gas-ribbed membrane 1, and a strip-shaped opening and closing structure 2 is arranged on the rib foot 11 of the gas-ribbed membrane 1, and the opening and closing structure 2 is used to make the gas-ribbed membrane 1 communicate or be sealed relative to the outside.

[0043] The first limiting member 31 is located on one side of the length direction of the opening and closing structure 2 on the outer surface of the gas-ribbed membrane 1, and the second limiting member 32 is located on the other side of the length direction of the opening and closing structure 2 on the outer surface of the gas-ribbed membrane 1; there is at least one intersection point between the projections of the first limiting member 31 and the second limiting member 32 on the outer surface of the gas-ribbed membrane 1 and the opening and closing structure 2 in the connected state. The first limiting member 31 and the second limiting member 32 are used to be detachably connected to each other to form a stable structure 3 that covers part of the opening and closing structure 2 and stabilizes the opening and closing structure 2.

[0044] In practical applications, the gas-ribbed membrane 1 generally presents a shape similar to an arch, such as Figure 7 shown is a schematic structural diagram of one half of the gas-ribbed membrane 1 and a schematic diagram of the relative position of the rib foot 11 of the gas-ribbed membrane 1 on the gas-ribbed membrane 1.

[0045] In practical applications, the strip-shaped opening and closing structure 2 can extend in different directions. In a specific embodiment, the opening and closing structure 2 can be arranged along the extending direction of the perimeter of the cross-section of the gas-ribbed membrane 1 in the radial direction, or along the direction perpendicular to the cross-section of the gas-ribbed membrane 1 in the radial direction, or can be obliquely arranged on the surface of the gas-ribbed membrane 1.

[0046] In practical applications, there can be multiple first limiting members 31 and the second limiting members 32 respectively. Each first limiting member 31 provided on one side in the length direction of the opening and closing structure 2 can be detachably connected to any second limiting member 32 provided on the other side in the length direction of the opening and closing structure 2.

[0047] In some specific embodiments, the first limiting member 31 and the second limiting member 32 include an elastic band. By providing the elastic band, the connection between the first limiting member 31 and the second limiting member 32 can be made more elastic and have greater tensile strength, and can adapt to the stability requirements of the air rib film 1 in different inflation intensity states.

[0048] In some specific embodiments, one of the first limiting member 31 and the second limiting member 32 includes a first connecting band, and the other includes a second connecting band. One end of the first connecting band is connected to one side in the length direction of the opening and closing structure 2, and the other end of the first connecting band is a free end; one end of the second connecting band is connected to the other side in the length direction of the opening and closing structure 2, and the other end of the second connecting band is a free end. The free end of the first connecting band is used for detachably connecting to the free end of the second connecting band.

[0049] In some specific embodiments, a length adjustment buckle 41 is provided at a position close to the free end of the first connecting band. The free end of the second connecting band is used for detachably connecting to the free end of the first connecting band through the length adjustment buckle 41 and adjusting the overall length after the first connecting band and the second connecting band are connected. In practical applications, as long as the overall length after the connection between the first connecting band and the second connecting band can be adjusted, the length adjustment buckle 41 can have various structural settings, such as Figure 1 and Figure 2 shown.

[0050] In practical applications, by adjusting the overall length after the first connecting band and the second connecting band are connected, this overall length can be made less than or equal to the length of the air rib film 1 between the connection point of the first connecting band on the surface of the air rib film 1 and the connection point of the second connecting band on the air rib film 1, so that the stable structure 3 formed between the first limiting member 31 and the second limiting member 32 can form a better fit with the air rib film 1, the contact area between the stable structure 3 and the surface of the air rib film 1 is larger, and more force application points can be provided.

[0051] In some specific embodiments, as Figure 3 shown, one of the first limiting member 31 and the second limiting member 32 is provided with an elastic buckle 51 near one end close to the opening and closing structure 2; the other of the first limiting member 31 and the second limiting member 32 is provided with an elastic buckle receiving member 52 that cooperates with the elastic buckle 51 near one end close to the opening and closing structure 2.

[0052] In practical applications, the elastic snap 51 is used to be placed in the elastic snap receiving member 52 to enable a detachable connection between the first limiting member 31 and the second limiting member 32. By adopting the elastic engagement setting between the elastic snap 51 and the elastic snap receiving member 52, the connection between the first limiting member 31 and the second limiting member 32 can be made simpler and easier to operate.

[0053] In some specific embodiments, as Figure 4 shown, one of the first limiting member 31 and the second limiting member 32 is provided with a buckle 61 and a snap pin 62 at one end close to the opening and closing structure 2; a plurality of positioning holes 63 are distributed on the other of the first limiting member 31 and the second limiting member 32. In practical applications, the positioning holes 63 are evenly distributed on the second limiting member 32, so that the user can adjust the connection length between the first limiting member 31 and the second limiting member 32 as needed. The buckle 61 is used to pass through the second limiting member 32; the snap pin 62 is used to pass through different positioning holes 63 on the second limiting member 32 to engage with the buckle 61 to adjust the connection tightness between the first limiting member 31 and the second limiting member 32.

[0054] In some specific embodiments, one of the first limiting member 31 and the second limiting member 32 is provided with a connection detection member at one end close to the opening and closing structure 2, and the connection detection member is used to detect whether there is a connection between the first limiting member 31 and the second limiting member 32.

[0055] In practical applications, the connection detection member can be a connection detection sensor connected to an upper computer, and the staff can remotely monitor whether the first limiting member 31 and the second limiting member 32 are safely connected through the signal sent by the connection detection sensor. Further, this connection detection sensor can also be provided with an alarm, and can emit a light signal or a sound signal for alarm when the first limiting member 31 and the second limiting member 32 are not safely connected, so as to prompt the staff to check whether they are safely connected.

[0056] In some specific embodiments, as Figure 5 and Figure 6 shown, it further includes a covering curtain 7, a first adhesive member 71 and a second adhesive member 72; one end of the covering curtain 7 is connected to a position on one side in the length direction of the opening and closing structure 2 on the outer surface of the air rib film 1. The first adhesive member 71 is arranged on the surface of the other end of the covering curtain 7 facing the air rib film 1; the second adhesive member 72 is arranged at a position on the outer surface of the air rib film 1 close to the other side of the opening and closing structure 2; the first adhesive member 71 is used for detachable connection with the second adhesive member 72 to enable the covering curtain 7 to cover the opening and closing structure 2.

[0057] In practical applications, by completely covering the opening and closing structure 2 with the covering curtain 7, the opening and closing structure 2 can be further isolated from the outside when not opened, providing protection for the opening and closing structure 2, effectively reducing the external wear suffered by the opening and closing structure 2, and enhancing its strength.

[0058] In some specific embodiments, the first adhesive member 71 and the second adhesive member 72 are a mutually cooperating Velcro structure, or snap structure, or zipper structure. For example, Figure 5 The figure shows a schematic diagram of the snap structure of the first adhesive member 71 and the second adhesive member 72. Figure 6 The figure shows a schematic diagram of the Velcro structure of the first adhesive member 71 and the second adhesive member 72.

[0059] In some specific embodiments, the stable structure 3 formed by the first limiting member 31 and the second limiting member 32 is symmetrically arranged with respect to the midline of the opening and closing structure 2 in the length direction. By making the stable structure 3 symmetrically arranged with respect to the opening and closing structure 2, the stress level of the stable structure 3 on the surface of the air rib film 1 with respect to the opening and closing structure 2 can be made uniform. In practical applications, each of the first limiting member 31 and the second limiting member 32 can also be symmetrically arranged with respect to the length direction of the opening and closing structure 2.

[0060] In some specific embodiments, the opening and closing structure 2 includes a zipper structure. In practical applications, this zipper structure is a high-strength, high-sealing, and waterproof zipper structure. By providing the zipper structure, the user can more conveniently open and close the opening and closing structure 2. In a specific embodiment, the zipper structure is arranged along the extending direction of the perimeter of the cross-section of the air rib film 1 in the radial direction.

[0061] In a specific usage process, the staff needs to inflate the air rib film 1 structure and fix it on a placement surface such as the ground. Specifically, it is necessary to increase the weight of the parts where the two ends of the air rib film 1 contact the ground, that is, it is necessary to increase the friction between the two end ribs 11 of the air rib film 1 and the placement surface to fix the ribs 11 on the placement surface.

[0062] In a specific embodiment, during the inflation process of the air rib membrane 1 or after the inflation of the air rib membrane 1 is completed, the staff can open the opening and closing structure 2 through a zipper. At this time, a connection is formed between the outside and the inflation space inside the air rib membrane 1 through this opened opening and closing structure 2. Then the staff can put external counterweight members such as sandbags into the positions corresponding to the two ends of the rib feet 11 in the air rib membrane 1 from this opening and closing structure 2, and then close the opening and closing structure 2 to enclose the counterweight members in the rib feet 11 of the air rib membrane 1. In this way, the weight can be increased inside at the positions corresponding to the rib feet 11 of the air rib membrane 1. Compared with the traditional method of adding anchoring devices outside the rib feet 11, placing the counterweight members inside the air rib membrane 1 can better bind the counterweight to the rib feet 11, effectively increasing the friction between the rib feet 11 of the air rib membrane 1 and the ground. At the same time, after the air rib membrane 1 is sealed, there is a pressure difference between its inside and the outside. The position of the opening and closing structure 2 has a lower strength on the surface of the air rib membrane 1 compared to other positions. At this time, by detachably connecting the first limiting member 31 and the second limiting member 32 on both sides of the opening and closing structure 2 in the length direction on the surface of the air rib membrane 1 to form a stable structure 3, and there is at least one intersection point between the projection of the stable structure 3 on the outer surface of the air rib membrane 1 and the opening and closing structure 2, the strength of the opening and closing structure 2 can be further consolidated, avoiding problems such as the opening and closing structure 2 bursting or cracking due to insufficient strength.

[0063] This embodiment provides an air rib type membrane structure with a stable structure. By arranging a strip-shaped opening and closing structure on the surface of the air rib membrane and respectively arranging a detachable connection between the first limiting member and the second limiting member on both sides in the length direction of the opening and closing structure, a stable structure that covers part of the opening and closing structure and stabilizes the opening and closing structure can be formed. Further, various connection relationships and connection structures between the first limiting member and the second limiting member are set, making the stable structure flexible and adjustable, and more secure, effectively improving the surface strength of the air rib membrane and the stability of the rib feet of the air rib type membrane structure placed on the ground.

[0064] The above is a specific description of the preferred embodiment of the present application. However, the present application is not limited to the embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present application. These equivalent deformations or substitutions are all included within the scope defined by the claims of the present application.
