Description

Technical Field

[0001] This invention relates to the field of air-supported membrane structure technology, and more specifically, to a construction device and method for a double-layer air-supported membrane. Background Technology

[0002] Traditional double-layer air-supported membrane structures often require two inflation devices to inflate the outer and inner membranes separately during construction. This necessitates two inflation devices along with their associated ductwork and fittings, increasing the complexity of the construction process and making the inflation procedure more intricate. Using only one inflation device and related ductwork fittings, primarily transferring them between the inner and outer membranes, further complicates construction and may lead to air leaks and poor inflation results. When an insulation layer is required, the above method involves filling the interlayer with insulation cotton after inflation. This method offers faster construction but suffers from discontinuous insulation.

[0003] In addition, the above construction methods have very low construction efficiency. The inflation and insulation work is easily affected by weather conditions such as rain, which leads to a longer construction period and makes it impossible to carry out multiple tasks at the same time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a construction device and construction method for a double-layer air membrane.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] The present invention provides a construction device for a double-layer air-supported membrane, the double-layer air-supported membrane comprising an outer membrane and an inner membrane located inside the outer membrane, with a sandwich layer between the two; the construction device includes an air supply device and a fiber duct located inside the inner membrane;

[0007] One end of the fiber duct is detachably connected to the air supply device, and the other end is connected to the internal space of the interlayer or the inner membrane.

[0008] The beneficial effects of this invention are: by setting up fiber ducts, the outer membrane and inner membrane can be inflated sequentially using a separate air supply device, eliminating the need for separate air supply devices for the outer and inner membranes, thus greatly simplifying the components and usage process of the construction equipment. After the outer membrane is lifted, an insulation layer can be laid on the outer surface of the inner membrane first, ensuring the continuity of insulation of the inner membrane and avoiding "cold bridges" caused by insulation interruptions.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the inner membrane has ventilation holes, and the outer surface of the inner membrane has a removable sealing element that can cover the ventilation holes; the other end of the fiber duct is connected to the interlayer through the ventilation holes.

[0011] The beneficial effect of adopting the above-mentioned further solution is that after the interlayer is inflated, the other end of the fiber duct needs to be removed from the inner membrane to continue inflating the inner membrane. At this time, the ventilation hole can be sealed first with a sealing device, and then the fiber duct can be removed to prevent the gas in the interlayer from flowing back into the inner membrane and affecting the inflation effect.

[0012] Furthermore, the other end of the fiber duct is detachably mounted on the inner surface of the inner membrane around the ventilation hole.

[0013] The advantage of adopting the above-mentioned further solution is that it facilitates the installation and removal of fiber ducts.

[0014] Furthermore, the fiber duct includes at least two duct sections, and the ends of two adjacent duct sections are detachably connected by an airtight zipper.

[0015] The advantage of adopting the above-mentioned further solution is that it facilitates the installation and removal of fiber ducts.

[0016] Furthermore, the air supply device includes an inflation device and a sheet metal duct; the inflation device is disposed outside the outer membrane, one end of the sheet metal duct is fixedly connected to the inflation device, and the other end passes through the outer membrane and the inner membrane in sequence, and is detachably connected to one end of the fiber duct.

[0017] The beneficial effect of adopting the above-mentioned further solution is that air can be transported through the sheet metal duct to the fiber duct through the inflation device to achieve inflation construction.

[0018] Furthermore, both the outer membrane and the inner membrane are provided with a sheet metal duct mounting hole, and the sheet metal duct passes through the two sheet metal duct mounting holes and is sealed to the outer membrane and the inner membrane.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by fixing the sheet metal air duct to the outer and inner membranes, the stability of the inflation process can be guaranteed, and the displacement of the sheet metal air duct can be prevented from affecting the inflation process and inflation effect.

[0020] Furthermore, the outer membrane is provided with at least one exhaust device.

[0021] The advantage of adopting the above-mentioned further solution is that the air pressure in the interlayer can be adjusted by properly venting through the venting device.

[0022] The present invention also provides a construction method for a double-layer air membrane, wherein the double-layer air membrane is inflated using the construction device described above.

[0023] Furthermore, the following steps are included:

[0024] S1. Place a fiber duct inside the inner membrane of the flat double-layer air membrane, connect one end of the fiber duct to the air supply device, connect the other end to the inner membrane, and connect it to the interlayer.

[0025] S2. Start the air supply device and inflate the interlayer with air through the fiber duct to form the outer membrane. After forming, turn off the air supply device.

[0026] S3. Connect the other end of the fiber duct to the internal space of the inner membrane;

[0027] S4. Restart the air supply device to allow the inner membrane to form, and complete the inflation process after forming.

[0028] The advantages of adopting the above-mentioned further solutions are that the above methods have the advantages of simple steps and high construction efficiency.

[0029] Furthermore, after step S2 is completed and before step S3 begins, thermal insulation cotton is laid on the surface of the inner membrane.

[0030] The beneficial effect of adopting the above-mentioned further solution is that after the outer membrane is laid, an insulation layer can be laid on the outer surface of the inner membrane first to ensure the insulation continuity of the inner membrane and avoid the occurrence of "cold bridges" with intermittent insulation.

[0041] 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.

[0042] like Figures 1-5 As shown, the construction device for a double-layer air membrane of the present invention is applicable to a double-layer air membrane including an outer membrane 10 and an inner membrane 20 located inside the outer membrane 10, with a sandwich between the two; the construction device includes an air supply device and a fiber duct 3 located inside the inner membrane 20; one end of the fiber duct 3 is detachably connected to the air supply device, and the other end communicates with the sandwich or the internal space of the inner membrane 20.

[0043] The construction device of the present invention, by setting up fiber duct 3, can realize the sequential inflation construction of outer membrane 10 and inner membrane 20 using a separate air supply device, without the need to set up separate air supply devices for outer membrane 10 and inner membrane 20, which greatly simplifies the components and usage process of the construction device.

[0044] Furthermore, the construction device of this invention first inflates the interlayer, causing the outer membrane 10 to be inflated and lifted, and then inflates the uncoiled inner membrane 20. In this way, after the outer membrane 10 is lifted, the insulation layer 30 can be laid on the outer surface of the inner membrane 20 first, ensuring the continuity of insulation of the inner membrane 20 and avoiding "cold bridges" that disrupt insulation; it also effectively improves construction efficiency; and laying the insulation layer inside the outer membrane 10 avoids the impact of weather conditions on the insulation work, making the cycle controllable and ensuring synchronization with other construction operations.

[0045] Preferably, the inner membrane 20 of the present invention has ventilation holes 201, and the other end of the fiber duct 3 is connected to the interlayer through the ventilation holes 201; so that the fiber duct 3 can send air into the interlayer through the ventilation holes 201.

[0046] Preferably, a sealing element is detachably installed on the ventilation hole 201; when the other end of the fiber duct 3 is connected to the inner membrane 20, the sealing element is separated from the ventilation hole 201; when the other end of the fiber duct 3 is separated from the inner membrane 20, the sealing element is installed on the ventilation hole 201; after the interlayer is inflated, the other end of the fiber duct 3 needs to be removed from the inner membrane 20 to continue inflating the interior of the inner membrane 20. At this time, the ventilation hole 201 can be sealed first with the sealing element, and then the fiber duct 3 can be removed to prevent the gas in the interlayer from flowing back into the inner membrane 20 and affecting the inflation effect.

[0047] Preferably, the sealing element and the outer surface of the inner membrane 20 around the ventilation hole 201 can be detachably connected by Velcro; the other end of the fiber duct 3 can be detachably connected to the inner surface of the inner membrane 20 around the ventilation hole 201 by Velcro.

[0048] In other embodiments, the other end of the fiber duct 3 may also be inserted into the ventilation hole 201 and detachably sealed to its edge.

[0049] Preferably, the fiber duct 3 includes at least two duct sections, and the ends of two adjacent duct sections are detachably connected by an airtight zipper 31.

[0050] Specifically, the purpose of connecting the duct section via the airtight zipper 31 is that, during the initial construction phase, depending on the actual situation, it may be necessary to repeatedly inflate the inner membrane 20 or the interlayer, which would require adjusting the specific connection position of the fiber duct 3. The airtight zipper 31 facilitates this adjustment process without requiring repeated disassembly and reassembly of the fiber duct 3.

[0051] Preferably, the air supply device includes an inflation device 1 and a sheet metal duct 2; the inflation device 1 is located outside the outer membrane 10, one end of the sheet metal duct 2 is sealed to the inflation device 1, and the other end passes through the outer membrane 10 and the inner membrane 20 in sequence, and is detachably connected to one end of the fiber duct 3; the inflation device 1 can transport air through the sheet metal duct 2 to the fiber duct 3 to realize inflation construction.

[0052] Preferably, the other end of the sheet metal duct 2 is detachably connected to one end of the fiber duct 3 via a canvas connector 22; wherein, the canvas connector 22 is a round-top, square-bottom connector, which can ensure good airtightness at the connection between the sheet metal duct 2 and the fiber duct 3.

[0053] Preferably, both the outer membrane 10 and the inner membrane 20 are provided with a sheet metal duct mounting hole 21. The sheet metal duct 2 passes through the two sheet metal duct mounting holes 21 and is fixedly connected to the outer membrane 10 and the inner membrane 20. Fixing the sheet metal duct 2 to the outer membrane 10 and the inner membrane 20 can ensure the stability of the inflation process and prevent the sheet metal duct 2 from shifting, which would affect the inflation process and inflation effect.

[0054] Preferably, at each metal duct mounting hole 21, the metal duct 2 is fixed to the membrane body of the outer membrane 10 or the inner membrane 20 by binding with waterproof and vapor-proof tape.

[0055] like Figure 7 As shown, in other embodiments of the present invention, the outer membrane 10 and the inner membrane 20 are fixed by a retaining wall 40. In this embodiment, the sheet metal duct 2 is pre-fixed on the retaining wall 40.

[0056] like Figure 8 As shown, in other embodiments of the present invention, the air-supported membrane structure is inflated by underground air supply. In this embodiment, the sheet metal duct 2 is buried underground beforehand, or an air duct is directly installed, so that the air inlet inside the inner membrane 20 is on the ground. The air inlet on the ground is fixed with bolts and angle steel on the outside, and one side of the angle steel presses the edge of the fiber duct 3 tightly. The space between the edge of the fiber duct 3 and the ground can be filled with airtight materials such as insulation cotton. Before the outer membrane 10 and the inner membrane 20 are laid flat, the fiber duct 3 is connected to the above-mentioned air inlet. The other end is connected to the inner surface of the inner membrane 20 using Velcro fasteners when the inner membrane 20 is laid.

[0057] Preferably, the outer membrane 10 is provided with at least one venting zipper 101; when the inner membrane 20 is inflated, the air pressure in the interlayer will change. Therefore, before inflating the inner membrane 20, the air pressure in the interlayer can be adjusted by venting the air through the venting zipper 101.

[0058] The construction method of the double-layer air-supported membrane of the present invention uses the above-mentioned construction device to inflate the double-layer air-supported membrane. Specifically, it includes the following steps:

[0059] S1. Place a fiber duct 3 inside the inner membrane 20 of the flat double-layer air membrane, connect one end of the fiber duct 3 to the air supply device, connect the other end to the inner membrane 20, and connect it to the interlayer.

[0060] Preferably, the air supply device can be assembled before step S1. Specifically, the sheet metal duct 2 is first fixed to the outer membrane 10 and the inner membrane 20, and then one end of it is connected to the inflation device 1.

[0061] S2. Start the air supply device and inflate the interlayer with air through the fiber duct 3 to form the outer membrane 10.

[0062] The instruction manual is required because the air film will continuously leak air, and the air supply device needs to be continuously supplied with air after it is turned on. Therefore, after this step is turned on, the air supply device should never be turned off.

[0063] In actual operation, after completing step S2, the staff enters the interlayer. At this time, the inner membrane 20 is still laid on the ground, while the outer membrane 10 has been formed.

[0064] Preferably, after step S2 is completed and before step S3 is started, the worker evenly lays the insulation layer 30 on the surface of the inner membrane 20 in the interlayer to ensure the continuity of insulation of the inner membrane 20 and avoid the occurrence of "cold bridges" with intermittent insulation. The insulation layer 30 is made of insulation cotton.

[0065] S3. After the insulation layer 30 is completed, the workers remove the other end of the fiber duct 3 from the inner membrane 20 in the interlayer and cover the ventilation hole 201 with a sealing piece. Then, the workers enter the inner membrane 20 and disconnect the duct section of the fiber duct 3 through the airtight zipper 31, so that the fiber duct 3 is connected to the internal space of the inner membrane 20. At this time, the inflation device 1 inflates the inner membrane 20.

[0066] S4. Initially, when inflating the inner membrane 20, it is laid on the ground. At this time, the interlayer is under positive pressure. To smoothly inflate the inner membrane 20, the venting device on the outer membrane 10 is first activated to allow the inner membrane 20 to rise and form. After forming, the inflation process is completed. The completed air-supported membrane structure is as follows: Figure 6 As shown.

[0067] Finally, after the air membrane is operating stably, the fiber duct 3 can be removed.

[0068] It should be noted that the outer membrane 10 and inner membrane 20 of the air-supported membrane are specifically fixedly connected to the ground or retaining wall 40 by angle steel. During construction, when workers enter the interlayer from the outside of the air-supported membrane or into the inner membrane 20, some of the angle steel can be disassembled to form a passage for personnel to pass through, thus enabling the above-mentioned construction operations to be completed.

[0069] In one embodiment of the present invention, after the above construction process is completed, one end of the fiber duct 3 can be completely disassembled from the sheet metal duct 2. At this time, an air outlet is installed at the other end of the sheet metal duct 2 so that it can be directly connected to the internal space of the inner membrane 20 and can be used as a side air outlet in the subsequent use of the air membrane structure.

[0070] In another embodiment of the present invention, after the above construction process is completed, the fiber duct 3 can be suspended along the inner surface of the inner membrane 20 and used as a device to maintain the internal space pressure of the inner membrane 20 in the subsequent use of the air membrane structure.
