Description

Technical Field

[0001] This invention relates to the field of air-supported membrane structure technology, and more specifically, to a connecting device for an aluminum channel in an air-supported membrane structure. Background Technology

[0002] The fixing device for the air-supported membrane structure can fix the air-supported membrane to prevent it from collapsing and leaking.

[0003] In existing technologies, an aluminum groove is often used to fix the edge of the air-supported membrane. Patent CN211774573U discloses a specific aluminum groove structure for the air-supported membrane. When fixing the air-supported membrane, the edge is placed into the aluminum groove, and anti-corrosion wood is inserted into the groove to compress and fix the air-supported membrane between the wood and the inner wall of the aluminum groove. In addition, to enhance the stability of the fixing device, the aluminum groove is usually equipped with auxiliary structures of various shapes, such as protruding groove walls, limiting components, etc.

[0004] However, when two aluminum channels are joined together, due to construction techniques and other reasons, problems such as loose connections or deformation at the joints are inevitable. For example, when anti-corrosion wood is stuffed into the aluminum channel, gaps may appear due to loose connections. When there is water on the outer beam of the air-supported membrane structure, the water can seep into the room from the outside through the gaps in the aluminum channel.

[0005] Ordinary connectors cannot be used for the irregular structure of aluminum channels, and it is impossible to seal the gaps in the aluminum channels. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a connection device for an aluminum channel in an air-film structure.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0008] This invention provides a connecting device for an aluminum channel in an air-supported membrane structure. The connecting device has a hollow cavity, the sidewalls of which are cavity walls. The opposite sides and the top of the cavity are open. The cavity walls include an inner wall and an outer wall that are connected to each other, and the inner wall and the outer wall form a sandwich structure. The sides and the top edge of the sandwich structure are open. The inner wall is made of an elastically deformable material.

[0009] The beneficial effects of the above-mentioned technical solution of the present invention are as follows: its shape corresponds to the shape of the aluminum channel of the air film structure, so that the joints of the two aluminum channels can be inserted into the sandwich structure of the connecting device respectively. In this way, the connecting device can cover the joints of the two aluminum channels, avoiding gaps caused by the two aluminum channels not being tightly connected, thereby preventing water from the outside from seeping in.

[0010] Furthermore, the inner wall and the outer wall are fixedly connected by connecting ribs; the connecting ribs are located in the middle of the sandwich structure.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the connecting rib divides the sandwich structure into two parts; in this way, when the ends of the two aluminum channels are inserted into the sandwich structure of the same connecting device, they are located on both sides of the connecting rib, thereby realizing the connection of the two aluminum channels.

[0012] Furthermore, both the outer wall and the connecting ribs are made of elastically deformable materials.

[0013] The advantage of adopting the above-mentioned further solution is that it makes it more adaptable to the shape of the aluminum channel.

[0014] Furthermore, the side edge of the outer wall is provided with multiple notches, which can accommodate the limiting wing extending outward from the outer wall of the aluminum groove.

[0015] The advantage of adopting the above-mentioned further solution is that it makes the connection between the aluminum channel and the connecting device more secure.

[0016] Furthermore, each side of the cavity wall has at least one protrusion that protrudes outward from the cavity; the protrusion extends through the two open sides of the cavity.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the protrusion can accommodate the buried rope, and through the action of the buried rope and the inner wall of the protrusion, the air film located between the two can be firmly fixed.

[0018] Furthermore, the protrusion is located near the lower part of the cavity.

[0019] The beneficial effect of adopting the above-mentioned further solution is to further improve the stability of the fixed air film.

[0020] Furthermore, one side of the cavity wall has two protrusions arranged vertically.

[0021] The beneficial effect of adopting the above-mentioned further solution is to further improve the stability of the fixed air film.

[0022] This invention provides a fixing device for an air-film structure, having the connecting device described above. It includes multiple aluminum channels, with one adjacent end of two aluminum channels respectively inserted into the sandwich structure of the same aluminum channel fixing device; it also includes preservative-treated wood, which is installed in the cavity and abuts against the aluminum channels located within the sandwich structure.

[0023] The present invention provides an air film structure having the fixing device as described above. Attached Figure Description

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] The connecting device for an aluminum channel in an air-film structure of the present invention has a hollow cavity 1 and a cavity wall 2; the opposite sides and the top of the cavity 1 are open; the cavity wall 2 includes an inner wall 21 and an outer wall 22 that are stacked and connected to each other, the inner wall 21 and the outer wall 22 forming a sandwich structure, the sides and the top edge of the sandwich structure are open; the opening of the sandwich structure allows the outer wall of the aluminum channel 3 to be inserted; the inner wall 21 is made of an elastically deformable material; and it can abut against the aluminum channel 3 located in the sandwich structure.

[0038] The aluminum channel connecting device of the present invention has a shape corresponding to the shape of the aluminum channel 3 of the air film structure, so that the joints of the two aluminum channels 3 can be inserted into the sandwich structure of the connecting device respectively. In this way, the connecting device can cover the joints of the two aluminum channels 3, avoiding gaps caused by the two aluminum channels 3 not fitting tightly, thereby preventing water from the outside from seeping in.

[0039] The inner wall 21 and outer wall 22 of the aluminum channel connecting device of the present invention are fixedly connected by a connecting rib 23; the connecting rib 23 divides the sandwich structure into two parts; in this way, when the ends of the two aluminum channels 3 are inserted into the sandwich structure of the same connecting device, they are located on both sides of the connecting rib 23, thereby realizing the connection of the two aluminum channels 3.

[0040] Preferably, the material of the connecting rib 23 is also an elastically deformable material; in this way, when connecting the two aluminum channels 3, the ends of the two aluminum channels 3 can be clamped to the connecting rib 23 from both sides, and the connecting rib 23 and the ends of the two aluminum channels 3 are sealed and abutted, thereby achieving further sealing of the gap between the two aluminum channels 3 and preventing external water from penetrating into the interlayer and into the gap between the two aluminum channels 3.

[0041] Preferably, the outer wall 22 is made of an elastically deformable material; by using an elastically deformable material to make the outer wall 22, the cavity wall 2 can better adapt to the shape of the aluminum groove 3 when it is connected with the aluminum groove 3.

[0042] Preferably, the outer wall 22 is provided with multiple notches 221, which can accommodate the limiting wings 31 on the outer wall of the aluminum groove 3. When fixing the air film structure, to further improve the stability of the fixing device, limiting wings 31 are generally provided on the outer wall of the aluminum groove 3. The shapes of the limiting wings 31 vary, but they generally extend outward from the aluminum groove 3. The connecting device of the present invention has notches on its outer wall 22 to accommodate the limiting wings 31, which allows for better cooperation with the aluminum groove 3 when the interlayer structure is inserted. Thus, the setting of the limiting wings 31 does not affect the installation of the aluminum groove 3 and the connecting device, and the connecting device does not enclose the limiting wings 31, thus affecting their limiting function.

[0043] Preferably, at least one protrusion 24 is provided on any side of the cavity wall 2, protruding outward from the cavity 1; the protrusion 24 extends through the two open sides of the cavity 1; the protrusion 24 is used to accommodate the buried rope 41. One side wall of the aluminum trough 3 has an outwardly protruding structure. When fixing the air film structure, the edge of the air film 4 is located inside the aluminum trough 3. The protruding structure of the aluminum trough 3 accommodates the buried rope 41. When the anticorrosive wood 5 is inserted into the aluminum trough 3, the anticorrosive wood 5 can fix the buried rope 41 within the protruding structure, thereby preventing the air film 4 from falling out of the aluminum trough 3. By providing the protrusion 24 on the cavity wall 2 of the connecting device of the present invention, and making it correspond to the protruding structure of the aluminum trough 3, the connecting device can connect to the aluminum trough 3 with the protruding structure.

[0044] The structure of the present invention will be illustrated by specific embodiments below:

[0045] Example 1

[0046] The specific structure of the connection device in this embodiment is as follows:

[0047] like Figure 1 As shown, the cavity 1 of the connecting device has a concave structure with open front and rear sides. The width and height of the cavity wall 2 on the left and right sides are equal. The cavity wall 2 includes a stacked inner wall 21 and an outer wall 22, which are connected side by side by a connecting rib 23. There is a gap between the inner wall 21 and the outer wall 22, forming a sandwich structure. The opening of the sandwich structure faces the front and rear sides. When connecting the two aluminum channels 3, one end of each aluminum channel 3 is inserted into the sandwich structure from the front and rear directions of the connecting device, respectively. The inner wall 21 and the outer wall 22 are fixedly connected by the connecting rib 23. In this embodiment, the connecting rib 23 is located at the vertical centerline of the cavity walls 2 on both sides, which can divide the sandwich structure into a sandwich space with equal front and rear sides.

[0048] The specific shape of the connecting device in this embodiment corresponds to an aluminum groove 3 with a specific structure.

[0049] The aluminum channel 3 includes a left side wall, a right side wall, and a bottom side wall. Two vertically parallel limiting wings 31 are provided on the outer sides of both the left and right side walls. The limiting wings 31 are arranged along the length of the aluminum channel 3 and extend outwards. The limiting wings 31 on the two side walls are symmetrically arranged with respect to the vertical center line of the aluminum channel 3. Corresponding to the above structure of the aluminum channel 3, the left and right outer walls of this embodiment are respectively provided with notches 221 corresponding to each limiting wing 31.

[0050] The upper edges of the left and right side walls of the aluminum channel 3 extend outward. Corresponding to this structure, in the connecting device of this embodiment, the upper edge of the inner wall 21 also extends outward, and a notch 221 is provided on the lower side of the outer extension, so that when the aluminum channel 3 is inserted into the sandwich structure, its upper outer edge is covered by the inner wall 21 of the connecting device.

[0051] In this embodiment, the left and right side walls of the aluminum channel 3 are provided with two downwardly extending limiting feet at the connection points with the bottom side wall. Corresponding to this structure, in the connecting device of this embodiment, the connection points between the two outer walls and the bottom outer wall are provided with corresponding notches 221, so that when the aluminum channel 3 is inserted into the sandwich structure, the two limiting feet can be accommodated in these two notches 221.

[0052] In this embodiment, the aluminum channel 3 can stably fix the air film 1, and the limiting feet provided on it can further enhance stability. The connecting device corresponding to the structure of the aluminum channel 3 can effectively implement a sealed connection of the aluminum channel 3.

[0053] like Figure 6 As shown, the right side wall of the aluminum channel 3 has an outwardly protruding structure for accommodating the buried rope 41. This protruding structure is located below the limiting wing 31 and is arc-shaped. Corresponding to the above structure, in the connecting device of this embodiment, a protrusion 24 is provided on the right side cavity wall 2. This protrusion 24 corresponds to the protruding structure of the aluminum channel 3, allowing the protruding structure of the aluminum channel 3 to be inserted into the interlayer structure of the protrusion 24.

[0054] The connecting device in this embodiment is integrally formed, and all parts are made of elastically deformable materials.

[0055] The specific method of using the fixing device with the connecting device of this embodiment is as follows: one end of each of the two aluminum grooves 3 with the above structure is inserted into the sandwich structure of a connecting device to achieve connection. The edge of the air film 4 is placed in the cavity 1 of the connecting device near the right inner wall, and the embedded rope 41 integrated with the air film 4 is located in the protrusion 24. The anticorrosive wood 5 is inserted into the cavity 1, and the anticorrosive wood 5 can fill the cavity 1 and compress the embedded rope 41, thereby fixing the air film 4 in the protrusion 24.

[0056] Under the pressure of the anticorrosive wood 5 and the buried rope 41, the inner wall 21 of the connecting device undergoes outward elastic deformation and abuts against the aluminum groove 3 in the sandwich structure, thereby sealing the gap between the two aluminum grooves 3.

[0057] In this embodiment, the aluminum channel 3 can stably fix the air film, and the limiting fins 31 provided on it can enhance stability. The connecting device corresponding to the structure of the aluminum channel 3 can effectively seal the aluminum channel 3, preventing external moisture from penetrating into the gap between the two aluminum channels 3 and disrupting the environment inside the air film 4.

[0058] Example 2

[0059] The other structures in this embodiment are the same as in Embodiment 1.

[0060] like Figure 3 As shown, in addition, the bottom of the aluminum channel 3 in this embodiment does not have a limiting foot. Corresponding to this structure, in the connecting device of this embodiment, the connection between the outer walls on both sides and the outer wall at the bottom is closed, and no notch 221 is provided. For the aluminum channel 3 without a limiting foot, the connecting device of this embodiment can make the connection position of the two sections of the aluminum channel 3 have better sealing.

[0061] Example 3

[0062] like Figure 4 As shown, the other structures in this embodiment are the same as those in Embodiment 1.

[0063] Furthermore, the protruding structure on the aluminum channel 3 in this embodiment is a bent-protruding shape. Correspondingly, the protrusion 24 on the connecting device in this embodiment is also a bent-protruding shape.

[0064] Example 4

[0065] like Figure 5 As shown, the other structures in this embodiment are the same as those in Embodiment 1.

[0066] Furthermore, the aluminum channel 3 in this embodiment does not have a limiting wing 31. Two protruding structures are arranged vertically on the right side wall of the aluminum channel 3. Corresponding to these structures, the connecting device in this embodiment does not have a notch 221 on its outer wall 22, and has two protrusions 24 corresponding to the protruding structures of the aluminum channel 3.
