Heat insulation and heat preservation system of gas film

Abstract

The invention provides a thermal insulation system of a gas film, and relates to the technical field of gas film structures. The heat insulation system comprises a plurality of heat insulation units, a first connecting assembly, a second connecting assembly and a third connecting assembly. The plurality of heat insulation units are arranged in the interlayer of the gas film; the first connecting assembly is arranged on the gas film and located in the interlayer. The second connecting assembly is arranged on the heat insulation unit and connected with the first connecting assembly. The third connecting assemblies are used for connecting the adjacent heat insulation units. The first connecting assemblies are arranged on the gas film in advance, and during installation, the second connecting assemblies of the heat insulation units are connected with the first connecting assemblies, and then the adjacent heat insulation units are connected through the third connecting assemblies. Due to the fact that the connecting area of the heat insulation unit and the gas film is small, the gas film is not prone to wrinkling after the heat insulation unit is installed. By improving the laying installation mode of the heat insulation and heat preservation unit, the installation difficulty is reduced, and the attractiveness after installation is improved.

Description

Technical Field

[0001] This invention relates to the field of air-supported membrane structure technology, and in particular to a thermal insulation system for air-supported membrane structures, applicable to scenarios such as cultural and tourism air-supported membrane venues, sports air-supported membrane venues, or industrial air-supported membrane warehouses. Background Technology

[0002] Currently, air-supported membrane structures used in applications such as cold storage facilities and ski resorts require low-temperature environments. These structures demand high thermal insulation performance; for example, cold storage temperatures need to be maintained at around -18°C, and ski resort temperatures at around -5°C. If the thermal insulation performance of the air-supported membrane structure is weak, maintaining these temperatures will require a significant amount of additional energy.

[0003] In response, a solution has been proposed in related technologies (refer to patent application number CN202121017900.9), which involves applying heat insulation patches to the air film and then covering the air film with a protective film, forming a three-layer structure of air film, heat insulation layer, and protective film. Adjacent heat insulation patches are filled and bonded with a sealant to ensure the airtightness of the heat insulation layer.

[0004] However, after long-term use and verification, the above solution has obvious drawbacks and is no longer suitable for the current development requirements of air-supported membrane structures. The reasons are as follows:

[0005] 1. High installation difficulty: The thermal insulation patches need to be glued onto the surface of the air-supported membrane piece by piece. If the gluing operation is carried out after the air-supported membrane is inflated and formed, the installation of the protective film after gluing the thermal insulation patches will be difficult and unsafe due to the high-altitude operation. If the gluing operation is carried out before the air-supported membrane is inflated and formed, the cumulative installation error due to gluing one piece at a time will result in poor air-supported membrane forming effect and difficulty in forming the predetermined shape.

[0006] 2. Poor aesthetics after installation: For the pre-installed heat insulation patch scheme, due to the existence of cumulative installation errors, wrinkles are easily generated on the surface of the air membrane, resulting in poor aesthetics when viewed from inside the air membrane. This does not meet the design requirements for sports venues.

[0007] 3. Thermal insulation patches are prone to falling off: There is a temperature difference between the low-temperature environment inside the air membrane and the outside of the air membrane. Moisture is easily generated on the surface of the air membrane. It can easily seep through the bonding layer between the air membrane and the thermal insulation patch, causing the patch to fall off, and making repair difficult. Summary of the Invention

[0008] This invention addresses the shortcomings of existing technologies by providing an air-supported membrane thermal insulation system. By improving the laying and installation method of the thermal insulation unit, the installation difficulty is reduced and the aesthetics after installation are enhanced.

[0009] An embodiment of the first aspect of the present invention provides a thermal insulation system for an air-supported membrane, the thermal insulation system comprising a plurality of thermal insulation units, a first connecting component, a second connecting component, and a third connecting component, the core improvements of which include:

[0010] First connecting component: The first connecting component is disposed on the air film and located in the interlayer of the air film; the first connecting component includes a pull strap and a connecting piece, the connecting piece is connected to the surface of the air film, the pull strap is connected to the connecting piece, the pull strap is used to connect the first connecting component, the end of the pull strap is clamped between the connecting piece and the air film (or the pull strap and the connecting piece are integrally formed), and the pull strap is used to connect the second connecting component.

[0011] Second connecting component: The second connecting component includes a reinforcing strip, a fixing clip, a fixing connector and a buckle. The reinforcing strip is located on the insulation body of the heat insulation unit. The insulation body is a flexible structure. The fixing clip clamps the reinforcing strip from both sides opposite to the insulation body. The fixing connector is connected to the fixing clips on both sides. The reinforcing strip defines an arc-shaped portion for installing the buckle.

[0012] The third connecting component includes a first connecting part, a second connecting part, and an adjusting part. The first connecting part and the second connecting part are connected through the adjusting part to adjust the distance between the first connecting part and the second connecting part. The first connecting part is connected to the first heat insulation unit, and the second connecting part is connected to the second heat insulation unit. The first heat insulation unit and the second heat insulation unit are adjacent to each other.

[0013] Thermal insulation unit: Several thermal insulation units are installed in the interlayer of the air membrane.

[0014] The heat insulation unit is installed in the interlayer of the air membrane through the first and second connecting components to isolate the temperature inside and outside the air membrane. Adjacent heat insulation units are connected through the third connecting component, so that several heat insulation units form a whole, which makes the installation more secure and the sealing better. The heat insulation units will not have gaps when the air membrane shakes or vibrates due to external forces, thus improving the overall sealing performance.

[0015] An embodiment of the first aspect of the present invention provides a thermal insulation system for an air-supported membrane, which further includes the following improvements:

[0016] Improved design of the second connection component:

[0017] The insulation body is equipped with several reinforcing strips, which are parallel to each other.

[0018] Among them, the reinforcing strip is a ring structure and is sleeved on the insulation body, with the arc-shaped part extending out of the insulation body; or the reinforcing strip is a linear structure and is located on one side of the insulation body, with the end of the reinforcing strip wrapping around and connecting to the reinforcing strip to define the arc-shaped part; or the reinforcing strip is a linear structure and is located on one side of the insulation body, with both ends of the reinforcing strip connected to the insulation body, and the part between the two ends of the reinforcing strip defining the arc-shaped part; or the reinforcing strip is a linear structure, with one end of the reinforcing strip located on the first side of the insulation body and the other end located on the second side of the insulation body, the second side facing away from the first side, and the part between the two ends of the reinforcing strip defining the arc-shaped part.

[0019] The insulation body has a groove on one side of the arc-shaped or annular part, which is used to hide the arc-shaped or annular part.

[0020] Several fixing clips are evenly distributed, and the spacing between adjacent fixing clips on the same reinforcing strip ranges from 0.1M to 3M.

[0021] Gaskets are provided between adjacent fixing clips. The gaskets clamp the reinforcing strips from both sides of the insulation body facing away from each other. The fixing connectors are connected to the fixing clips on both sides.

[0022] Improved design of the third connection component:

[0023] The adjusting component includes a column, an adjusting rope, and a clamping component. The column has a cavity, an elastic reset element, and a clamping component. The adjusting rope passes through the column, and the clamping component can clamp the adjusting rope under the action of the elastic reset element.

[0024] Alternatively, the adjusting component may include a column, an adjusting rope, and a clamping component. The column has a cavity with an internal thread, and the clamping component has an external thread. The clamping component is screwed into the cavity, and the adjusting rope is threaded through the column. The clamping component can clamp the adjusting rope when it is screwed in.

[0025] By adopting the above technical solution, the present invention achieves the following beneficial effects:

[0026] 1. Easy installation and high safety: The first connecting component is pre-installed on the air membrane, and the second connecting component is set on the heat insulation unit. During installation, the second connecting component is first connected to the first connecting component (snap-on connection), and then the adjacent heat insulation units are connected through the third connecting component (rope connection), which is convenient, quick and easy to construct.

[0027] 2. Good aesthetics after installation: Due to the small connection area between the thermal insulation unit and the air membrane, the air membrane is less prone to wrinkles after the thermal insulation unit is installed.

[0028] 3. The thermal insulation unit is firmly installed and not easy to fall off: The connection area between the first connecting component and the air film is small, and the water vapor generated on the surface of the air film is not easy to accumulate, which has little impact on the first connecting component. Moreover, the water vapor has already evaporated (the thermal insulation unit and the air film are not tightly attached and have gaps). The thermal insulation unit will basically not fall off after installation, and the maintenance cost is low. Attached Figure Description

[0059] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] Appendix Figure 1 To be continued Figure 17 A double-layer air-film structure and its thermal insulation system are provided.

[0062] 1. Thermal insulation system

[0063] Reference Figures 1 to 6 As shown, the thermal insulation system includes a first connecting component 2, a second connecting component 3, a third connecting component 4, and several thermal insulation units 1.

[0064] Reference Figure 1 and Figure 4 As shown, the double-layer air-supported membrane structure includes a main membrane 5 and a secondary membrane 51. Both the main membrane 5 and the secondary membrane 51 are mounted on a base. The main membrane 5 and the base together define the internal space 7 of the air-supported membrane, and the main membrane 5 and the secondary membrane 51 together define the interlayer space 8. Both the internal space 7 and the interlayer space 8 are sealed spaces relative to the external environment. When air is introduced into the internal space 7, a pressure difference is created between the inside and outside of the main membrane 5, causing it to expand and bulge, forming a dome structure. When air is introduced into the interlayer space 8, a pressure difference is created between the inside and outside of the secondary membrane 51, causing it to expand and bulge. A thermal insulation unit 1 is located within the interlayer space 8, ensuring that the double-layer air-supported membrane structure has excellent thermal insulation performance thanks to the dual protection of the interlayer space 8 (which prevents direct heat exchange between the air in the internal space 7 and the outside air) and the thermal insulation unit 1 (which further slows down the rate of heat exchange between the air in the internal space 7 and the air in the interlayer space 8).

[0065] 2. Thermal insulation unit

[0066] Reference Figure 5 and Figure 6 As shown, a plurality of heat insulation units 1 are connected to the first connecting component 2 via the second connecting component 3, so that the plurality of heat insulation units 1 are fixed relative to the main membrane 5; the plurality of heat insulation units 1 are connected to each other via the third connecting component 4, further improving the fixing effect of the heat insulation units 1.

[0067] Reference Figure 3As shown, the thermal insulation unit 1 includes an insulation body 11. The insulation body 11 of the thermal insulation unit 1 includes an outer layer of fabric coated with a heat-reflective material (such as aluminum foil), and a porous material (such as foam, fiberglass, etc.) filling the outer layer of fabric. The insulation body 11 is a flexible structure. Located in the air-supported membrane body ( Figure 1 The insulation body 11 located at the position of the main membrane 5 is rectangular; the insulation body 11 located at the air-supported gable wall 9 is rectangular and triangular. The edges of the insulation body 11 are provided with stepped or sloping structures 12 (i.e., sloping structures 12 are provided on both sides and at both ends of the insulation body 11) to create a misalignment when adjacent insulation bodies 11 come into contact, improving the sealing between the insulation bodies 11. Alternatively, the insulation body 11 may also have sloping structures 12 on both sides or at both ends. The location of the sloping structures 12 is not uniquely limited here.

[0068] 3. First connecting component

[0069] Reference Figure 2 and Figure 6 As shown, the first connecting component 2 is disposed on the outer surface of the main membrane 5 and located within the interlayer space 8. The first connecting component 2 includes a pull strap 21 and a connecting piece 22. The connecting piece 22 is connected to the main membrane 5 by welding, adhesive bonding, or other methods. Similarly, the pull strap 21 is connected to the connecting piece 22 by welding, adhesive bonding, or other methods. The end of the pull strap 21 is sandwiched between the connecting piece 22 and the main membrane 5, which allows the tensile force on the pull strap 21 to be transferred to the connecting piece 22. This increases the contact area between the connecting piece 22 and the main membrane 5, thereby improving the strength of the first connecting component 2. Alternatively, the pull strap 21 can be integrally formed with the connecting piece 22, which can further improve the strength of the first connecting component 2.

[0070] 4. Second connecting component

[0071] Reference Figure 6 As shown, the second connecting component 3 includes a reinforcing strap 31, a fixing clip 32, a fixing connector 33, and a buckle 34.

[0072] Reference Figure 6 As shown, the reinforcing band 31 is a ring-shaped high-strength strap, which is fitted onto both sides of the insulation body 11, and the reinforcing bands 31 on both sides are parallel to each other. The fixing clips 32 are metal or plastic sheets, which clamp the reinforcing bands 31 from opposite sides of the insulation body 11. The fixing connectors 33 are bolts (preferably carriage bolts), which pass through the insulation body 11 and are connected to the fixing clips 32 at both ends. The reinforcing bands 31 define an arc-shaped portion 311 (or an annular portion), and the buckles 34 are installed on the arc-shaped portion 311 (or an annular portion).

[0073] Reference Figure 6As shown, the fixing clips 32 are evenly distributed along the length of the reinforcing strip 31, wherein the spacing between adjacent fixing clips 32 on the same reinforcing strip 31 ranges from 0.1M to 3M. This design enables the reinforcing strip 31 and the insulation body 11 to be subjected to more uniform stress, and avoids the outer layer of the insulation body 11 being torn, which would affect the heat insulation effect.

[0074] Reference Figure 6 As shown, in order to prevent gaps between adjacent thermal insulation units 1, the thermal insulation unit 1 is provided with a groove 13, and the arc-shaped part 311 (or annular part) of the reinforcing band 31 can be inserted into the groove 13, with only the end and the buckle 34 exposed. When adjacent thermal insulation units 1 abut against each other, the arc-shaped part 311 (or annular part) will not push up the insulation body 11 to form a gap.

[0075] Reference Figure 7 As shown, in some embodiments, a spacer 35 can be provided between adjacent fixing clips 32 to enhance the connection between the reinforcing strip 31 and the insulation body 11, thereby reducing the use of fixing clips 32 and saving materials. For example, when the distance between the two nearest fixing clips 32 is 2M, the distance between the nearest fixing clip 32 and the spacer 35 can be set to 1M.

[0076] Reference Figure 8 As shown, in some embodiments, the fixing clips 32 can all be made of gaskets 35, such as metal gaskets 35 or plastic gaskets 35. For the small thermal insulation unit 1, using gaskets 35 can save material costs while ensuring installation strength.

[0077] It should be noted that the reinforcing strip 31 also includes the following embodiments:

[0078] Reference Figure 15 As shown, the reinforcing strip 31 has a linear structure and is located on one side of the insulation body 11. The end of the reinforcing strip 31 is wrapped around and connected to the reinforcing strip 31 to define the arc-shaped part 311 (or the ring-shaped part).

[0079] Reference Figure 16 As shown, the reinforcing strip 31 has a linear structure and is located on one side of the insulation body 11. Both ends of the reinforcing strip 31 are connected to the insulation body 11, and the portion between the two ends of the reinforcing strip 31 defines an arc-shaped portion 311 (or an annular portion).

[0080] Reference Figure 17 As shown, the reinforcing strip 31 has a linear structure. One end of the reinforcing strip 31 is located on the first side of the insulation body 11, and the other end is located on the second side of the insulation body 11. The second side faces away from the first side. The portion between the two ends of the reinforcing strip 31 defines an arc-shaped portion 311 (or an annular portion).

[0081] 5. Third connection component

[0082] Reference Figure 10 As shown, the third connecting component 4 includes a first connecting part 41, a second connecting part 42, and an adjusting part 44.

[0083] Reference Figure 10 As shown, the first connecting component 41 and the second connecting component 42 are connected by an adjusting component 44 to adjust the distance between them. Two adjacent thermal insulation units 1 are respectively the first thermal insulation unit and the second thermal insulation unit. The first connecting component 41 is connected to the first thermal insulation unit (for example, the first connecting component 41 is fixed to the fixing clip 32 by a fixing connector 33), and the second connecting component 42 is connected to the second thermal insulation unit. To prevent the insulation body 11 from being scratched by the fixing clip 32, a cushioning sponge component 36 or a rubber component is provided between the fixing clip 32 and the insulation body 11.

[0084] Reference Figure 10 As shown, the first connecting component 41 and the second connecting component 42 are steel wire ropes. Both the first connecting component 41 and the second connecting component 42 have adjustable locking portions 43 at their ends. The steel wire rope passes through one side of the locking portion 43 and its end wraps back through the other side of the locking portion 43, forming a loop-shaped connecting portion 431. A spring is provided inside the locking portion 43; pressing the locking portion 43 releases the steel wire rope, and releasing the locking portion 43 locks the steel wire rope, thereby adjusting the inner diameter of the loop structure so that the first connecting component 41, the second connecting component 42, and the fixed connecting member 33 can be connected. In some embodiments, the locking portion 43 is provided with a screw; after adjusting the size of the loop-shaped connecting portion 431, the steel wire rope can be tightened by screwing in the screw.

[0085] Reference Figure 9 As shown, in some embodiments, the annular connecting portion 431 of the first connecting member 41 and the second connecting member 42 can be designed as a metal pressure plate or a high-strength pressure plate with through holes. By pressing the iron plate with the fixing connector 33 and the fixing clip 32, a good fixing effect can be achieved, and the cost is lower. The third connecting assembly 4 can also remove the adjusting component 44, so that the first connecting member 41 and the second connecting member 42 are connected by a non-adjustable pull rope.

[0086] Reference Figures 11 to 13 As shown, in some embodiments, both the first connecting member 41 and the second connecting member 42 have non-adjustable annular connecting portions 431 at their ends. The annular connecting portions 431 can be directly sleeved on the fixed connecting member 33 and then clamped by the fixed connecting member 33 and the fixed clamping piece 32.

[0087] It should be noted that, Figure 10 ,as well as Figures 11 to 13 In both embodiments, the structure of the adjusting component 44 is the same; the structure of the adjusting component 44 is described below. (Refer to...) Figure 13 As shown, the adjusting component 44 includes a column 441, an adjusting rope 442, and a clamping component 443 movably disposed on the column 441. The column 441 has an internal cavity with internal threads. The clamping component 443 has external threads that mate with the internal threads of the cavity. The column 441 also has a first through hole allowing the first connecting component 41 and the second connecting component 42 to pass through, and a second through hole allowing the adjusting rope 442 to pass through. When it is necessary to adjust the distance between the first connecting component 41 and the second connecting component 42, the clamping component 443 is rotated outwards, and then the adjusting rope 442 is pulled to bring the first connecting component 41 closer to the second connecting component 42. After adjusting the distance, the clamping component 443 is rotated inwards to lock the adjusting rope 442.

[0088] Additionally, refer to Figure 14 As shown, in some embodiments, an elastic reset member 444 may also be provided in the cavity, eliminating the internal thread of the cavity and the external thread of the clamping member 443, and the clamping member 443 relies on the elastic reset member 444 to clamp the adjusting rope 442.

[0089] It should be noted that the third connecting component 4 can be used not only to connect the heat insulation unit 1 in the span direction of the air film, but also to connect the heat insulation unit 1 in the length direction of the air film.

[0090] For Example 1, the installation process of the heat insulation unit 1 is as follows:

[0091] 1. Install the heat insulation unit after the air-supported membrane is inflated and formed.

[0092] After the main membrane 5 is inflated and bulges, the heat insulation unit 1 is first installed at the central axis of the main membrane 5, along the length of the air membrane. The second connecting component 3 of the heat insulation unit 1 is connected to the first connecting component 2 on the surface of the main membrane 5 (the buckle 34 is installed on the pull strap 21, where the first connecting component 2 is pre-installed on the main membrane 5), forming the heat insulation unit 1 for bearing force along the length of the air membrane. Then, the remaining heat insulation units 1 are installed along the span of the air membrane, and adjacent heat insulation units 1 are connected one by one through the third connecting component 4, so that the heat insulation units 1 cover the main membrane 5. Finally, the sub-membrane 51 is installed, and air is filled into the interlayer space 8.

[0093] 2. Install heat insulation unit before air-supported membrane inflation.

[0094] After the main membrane 5 is laid, the heat insulation unit 1 is first installed at the central axis of the main membrane 5, along the length of the air membrane. The second connecting component 3 of the heat insulation unit 1 is connected to the first connecting component 2 on the surface of the main membrane 5 (the buckle 34 is installed on the pull strap 21, where the first connecting component 2 is pre-installed on the main membrane 5), forming the heat insulation unit 1 for bearing force along the length of the air membrane. Then, the remaining heat insulation units 1 are installed along the span of the air membrane, and the adjacent heat insulation units 1 are connected one by one through the third connecting component 4, so that the heat insulation units 1 cover the main membrane 5. Then, the secondary membrane 51 is laid, and finally, air is filled into the internal space 7 and the interlayer space 8, wherein the air pressure in the interlayer space 8 is greater than the air pressure in the internal space 7, which is greater than the external air pressure.

[0095] Both of the above installation methods have the advantages of low difficulty in high-altitude operations, high safety, and good aesthetics after installation.

[0096] Reference Figure 1 As shown, in Embodiment 1, the shape of the thermal insulation unit 1 on the main body of the air-supported membrane (main membrane 5 in the figure) differs from its shape on the gable wall 9 of the air-supported membrane, mainly determined by the cutting shape of the membrane material. The shape of the thermal insulation unit 1 corresponds to the cutting shape of the membrane material. For example, the thermal insulation unit 1 on the gable wall 9 includes triangular and rectangular shapes. Adjacent thermal insulation units 1 are connected to each other through a first connecting component 2, a second connecting component 3, and a third connecting component 4.

[0097] Example 2

[0098] Appendix Figure 18 and attached Figure 19 A double-layer air-film structure (air rib type) and its thermal insulation system are provided.

[0099] The thermal insulation system structures of Example 2 and Example 1 are the same. Here, we will focus on the scheme of installing the thermal insulation system on a double-layer air-supported membrane structure.

[0100] Reference Figure 18 and Figure 19 As shown, the double-layer air-supported membrane structure includes an outer membrane 6 and an inner membrane 61. The outer membrane 6 is connected to the base, and the outer membrane 6 and the base together define the internal space 7 of the air-supported membrane, forming a dome structure. The inner membrane 61 is located inside the outer membrane 6, and the inner membrane 61 and the outer membrane 6 together define a sandwich space 8. The inner membrane 61 and the outer membrane 6 form air ribs, and several air ribs are interconnected to form air rib units, which cover the outer membrane 6.

[0101] Reference Figure 19As shown, the heat insulation unit 1 is located inside the inner membrane 61 and within the interlayer space 8. The first connecting component 2 is located inside the outer membrane 6, and the second connecting component 3 is located on the heat insulation unit 1 and connected to the first connecting component 2, thereby allowing the heat insulation unit 1 to be installed on the outer membrane 6.

[0102] For Example 2, the installation process of the heat insulation unit 1 is as follows:

[0103] After the air ribs of the air-supported membrane are inflated, a heat insulation unit 1 is installed in each air rib cavity (the interlayer space 8 formed by the outer membrane 6 and the inner membrane 61). The size of the heat insulation unit 1 at the air-supported membrane body is customized according to the size of the air rib cavity. Generally, only one heat insulation unit 1 is set in a complete air rib cavity from the center of the air-supported membrane to the bottom of both sides (span direction). The same applies to the heat insulation unit 1 at the air-supported membrane gable 9. The heat insulation unit 1 is inserted into the upper opening of the outer membrane 6 and the inner membrane 61 and pulled down with a rope, or it is inserted into one end of the air rib cavity and pulled to the other end with a rope. The hanging point (first connecting component 2) of the heat insulation unit 1 is set on the inner surface of the outer membrane 6. The heat insulation unit is connected to the first connecting component 2 through the second connecting component 3.

[0104] In addition, if multiple heat insulation units 1 need to be installed in the air rib cavity, the multiple heat insulation units 1 can be connected together through the third connecting component 4, and then the heat insulation units 1 can be installed into the air rib cavity using the above method.

[0105] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this embodiment should be included within the protection scope of this embodiment.
