Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air film, in particular to a large-span air rib type inflatable film structure. BACKGROUND

[0002] Foundation pit engineering is a common and key link. Traditional foundation pit support structures mainly include pile support, underground continuous wall, soil nailing wall, anchor support, etc. The air film structure is a kind of space structure formed by using high-strength flexible film material and inflating it to form a certain rigidity and stability. Its basic principle is to use the supporting effect of air to make the film material produce tension, thereby resisting external load. The air film structure has the advantages of light weight, large span, fast construction speed, low cost, etc. Compared with traditional rigid structures, the air film structure does not need a large number of supporting members and can realize large-span column-free space to provide an open use area inside the building. At the same time, the construction process of the air film structure is relatively simple, only the splicing of the film and the installation of the inflation equipment are needed on site, which greatly shortens the construction period. In addition, the material of the air film structure can be recycled, which meets the development concept of green building.

[0003] As prior art patent document with publication number CN219033547U, the patent document relates to the technical field of air support type air film structure and air rib type air film structure, in particular to an air film installation structure. The air film installation structure of the utility model includes an air film foundation layer and an inflated air film body, the lower end of the air film body is anchored on the air film foundation layer through an anchoring structure, both ends of the air film body are sealed and installed with a straight door wall body connected with the air film foundation layer, the lower end of the straight door wall body is provided with an opening, and a passageway door is installed at the opening, the outer part of the air film body is provided with an inflation pipeline communicating with the inner cavity thereof, and the air film foundation layer is surrounded by a drainage ditch with a cover plate corresponding to the peripheral area of the air film body. The special anchoring structure is fixed, so that the assembly between the air film body and the air film foundation layer is more stable, and at the same time, the overall water seepage prevention effect is also better.

[0004] In the existing technology system related to air-supported membrane structures for large-span foundation pits, some technical solutions enhance the stability of the air-supported membrane structure by carefully designing a base layer. Specifically, these technologies lay a base layer of specific materials and structures at the bottom of the foundation pit. Utilizing the friction and adsorption forces between the base layer and the air-supported membrane, the membrane is firmly fixed above the foundation pit, effectively resisting adverse factors such as external wind force and lateral soil pressure. This ensures that the air-supported membrane maintains good shape and structural integrity during the initial installation phase, providing a relatively safe and stable working environment for foundation pit operations. However, in actual foundation pit construction, the working face constantly changes as the project progresses. For example, during the layered excavation stage of the underground structure, the working face extends downwards to a certain depth after each layer of soil is excavated. During the construction of the underground main structure, work is also carried out in different areas according to the construction process. This requires the air-supported membrane to be able to move and adjust accordingly with the progress of the foundation pit operations. However, existing technologies with air-supported membrane base layers face the challenge of difficulty in moving the membrane. Because the air-supported membrane structure forms a relatively tight connection and fixation with the ground layer, moving the air-supported membrane requires first disrupting the connection structure between the air-supported membrane and the ground layer. This process is not only cumbersome and time-consuming, but also prone to damaging the air-supported membrane, affecting its integrity and sealing. Once the air-supported membrane is damaged, it needs to be repaired promptly; otherwise, the internal air pressure will become unstable, further threatening the safety of the excavation work. Therefore, this application proposes a large-span air-ribbed inflatable membrane structure. Summary of the Invention

[0019] Compared with the prior art, the present application has the following advantages:

[0020] 1. The plurality of air rib air films can form a protection after inflation, providing support and protection functions for the overall structure, and can be flexibly arranged according to different scene requirements. The gas feeding pipe is used for conveying gas, the inflation pipe is opened on one side of the gas feeding pipe, and can effectively feed gas into the plurality of air rib air films, ensuring that the air rib air films can be sufficiently inflated to maintain an inflated state and realize a protection function. The inflation pipe is used for supporting the plurality of air rib air films and providing a stable support base for the air rib air films. At the same time, the plurality of air rib air films can move, which facilitates adjustment of the positions of the air rib air films according to actual requirements. The moving seat is fixedly connected to the bottom of the mounting plate, providing a stable mounting base for the rollers, motors, positioning seats, air cylinders and other components. The reasonable structure design can withstand the force and vibration generated by these components during operation, ensuring the overall stability of the displacement assembly. The moving seat integrates a plurality of functional components to form a compact displacement unit. This integrated design reduces the connection points and space occupation between components, improves the reliability and maintainability of the displacement assembly. At the same time, it is also convenient for installation, debugging and replacement of the entire displacement assembly.

[0021] 2. The vortex sheet uniformly constructed inside the inflation pipe can guide the gas flowing through the inflation pipe to the gas rib air film into spiral turbulent flow. The spiral turbulent flow form of gas flow is more smooth, compared with ordinary gas flow, can effectively reduce the resistance of gas flow in the pipeline, so that the gas can be more quickly and efficiently filled into the gas rib air film, shorten the inflation time, improve the inflation efficiency, after the gas enters the gas rib air film, the spiral rib can continue to guide the rotation of the gas flow, further reduce the filling resistance of the gas flow, ensure that the gas rib air film can be quickly and uniformly expanded, the shaking rod arranged inside the inflation pipe can be hammered and vibrated, and the transmission assembly inside the gas exchange pipe is used to push the shaking rod to shake, which can apply vibration force according to the flow of gas flow. During the unfolding of the gas rib air film, there is static friction between the film surfaces. The vibration force can effectively reduce the static friction, so that the unfolding of the gas rib air film is more smooth, and it is helpful to release the stress of the folding area, reduce the damage of the film surface caused by stress concentration, and prolong the service life of the gas rib air film. When the accumulated snow covers the surface of the gas rib air film, the gravity of the accumulated snow will make the gas rib air film deform under pressure, and then drive the gas flow. The gas flow will disturb the touch flow plate to move, and the transmission assembly will make the shaking rod shake the gas exchange pipe. The shaking will be transmitted to the gas rib air film, so that the accumulated snow slides down, avoiding that the accumulated snow is too thick to cause too much pressure on the gas rib air film, and ensuring the safety of the whole structure. When the gas rib air film is subjected to an impact force outside the predetermined range, the excess gas flows back to the inflation pipe, which will make the ball move excessively, drive the probe to insert into the signal slot to transmit the electric signal, and give a warning to the stress state of the gas rib air film. The operator can take timely measures according to the warning information, such as checking the damage of the gas rib air film and adjusting the inflation pressure, to avoid damage of the gas rib air film caused by too much stress, and improve the safety and reliability of the whole structure.

[0041] Example two: please refer to Figures 1-11The application further provides a technical scheme, which is different from the technical scheme of the first embodiment, and is a large-span air rib type inflatable membrane structure, further comprising a vortex sheet 300 uniformly arranged in the interior of the inflatable pipe 102 for forming spiral turbulent flow of the gas, and a spiral rib 109 arranged in the interior of each air rib air film 100, and a shaking rod 310 arranged in the interior of the inflatable pipe 102 and capable of being hammered to vibrate, and a transmission assembly arranged in the interior of the inflatable pipe 102 and capable of pushing the shaking rod 310 to shake, wherein the vortex sheet 300 is arranged to guide the gas to form spiral turbulent flow when the gas passes through the inflatable pipe 102 to inflate the air rib air film 100, so as to reduce the resistance, and the spiral rib 109 arranged in the air rib air film 100 can continue to guide the rotation of the airflow, so as to reduce the filling resistance of the airflow, and the spiral rib 109 can improve the supporting force of the air rib air film 100, and the transmission assembly is arranged to push the shaking rod 310 to shake, so as to drive the inflatable pipe 102 to shake and provide the air rib air film 100 with small-amplitude shaking.

[0042] Further comprising a feedback column 400 arranged in the interior of the air exchange pipe 103, the feedback column 400 is provided with flexible pressing sheets 404 at both ends and capable of deforming along the airflow, the interior of the feedback column 400 is provided with a moving ball 402, and the interior of the moving ball 402 is provided with a feedback assembly for transmitting the deformation of the flexible pressing sheet 404 into an electric signal, the feedback column 400 and the feedback assembly are arranged to effectively detect the flow of the change of the air pressure and cooperate with the air blower 104 to compensate the gas in real time.

[0043] The transmission assembly comprises a plurality of side grooves 301 formed in the inside of the inflation pipe 102, and the inside of each of the plurality of side grooves 301 is slidably connected with a displacement frame 306; the inside of the side groove 301 is rotatably connected with a crank 307 which can abut against the displacement frame 306; one side of the displacement frame 306 is fixedly connected with a spring sheet 309, and one end of the spring sheet 309 is fixedly connected with a shaking rod 310; one end of the crank 307 abuts against the spring sheet 309; one side of the crank 307 is fixedly connected with a tension spring 308 for driving the crank 307 to reset; the inside of the shaking block 302 is fixedly connected with an abutting bead 303 which can abut against one side of the displacement frame 306; both ends of the shaking block 302 are fixedly connected with the side groove 301 through springs 311; one side of the shaking block 302 is fixedly connected with a connecting plate 304, and one end of the connecting plate 304 is fixedly connected with a touch flow plate 305; when the gas flows in the gas exchange pipe 103, the touch flow plate 305 is disturbed to move, so that the shaking block 302 is forced to move to drive the displacement frame 306 to swing back and forth, and in turn, one end of the crank 307 is continuously pressed against the spring sheet 309, so as to perform the power storage and release actions on the shaking rod 310, thereby driving the shaking rod 310 to continuously hammer the inside of the inflation pipe 102; according to the flow of the gas flow, the vibration force can effectively reduce the static friction between the membrane surfaces of the gas rib membrane 100 in the unfolding process, improve the stress release of the folding area, and at the same time, when the snow covers the surface of the gas rib membrane 100, the snow will be deformed under pressure to drive the gas flow, so that the touch flow plate 305 is forced to drive the shaking rod 310 to shake the gas exchange pipe 103, and the snow falls off.

[0044] The top of the touch flow plate 305 is fixedly connected with a side branch plate 407, and the inside of the side branch plate 407 is rotatably connected with a connecting crank 408 which is rotatably connected with a feedback column 400; the feedback assembly comprises a plurality of probes 406 fixedly connected in the inside of a displacement ball 402; the inside of the displacement ball 402 penetrates a support rod 403 which is fixedly connected with a flexible pressing sheet 404; the inside of the feedback column 400 is provided with a movable cavity 401 in which the support rod 403 is slidably connected; the inside of the movable cavity 401 is provided with a signal groove 405 which is matched with the probe 406; the flexible pressing sheet 404 is arranged to be pressed by the gas flow, so that the flexible pressing sheet 404 is deformed to drive the support rod 403 to move the displacement ball 402; when the pressing degree exceeds the bearing range, the probe 406 is electrically connected with the signal groove 405, and at this time, the too high conveying gas flow or the too high pressing force will be out of the standard, and needs to be adjusted.

[0045] Specifically, when the air flow moves in the inflation pipe 102, it will shake the touch flow plate 305, and then drive the shaking block 302 to move up and down, thereby driving the touching beads 303 to constantly touch the displacement frame 306. When the displacement frame 306 moves, it will constantly push the crank 307 to tilt and make one end of the crank 307 press the spring sheet 309, thereby storing power for the shaking rod 310. Subsequently, in the resetting process of the displacement frame 306, the shaking rod 310 hammers the inflation pipe 102 to make it shake, and the resonance force is transmitted to the air rib air film 100. When the air rib air film 100 is filled with gas, the internal air pressure is stable. When the air rib air film 100 is extruded by external force, the gas in the air rib air film 100 can flow back to the inside of the inflation pipe 102, so that the flexible pressing sheet 404 above the feedback column 400 is pushed down by the air flow, thereby driving the moving ball 402 to move in the movable cavity 401. When the air rib air film 100 is impacted by an impact force within a predetermined range, excessive gas flows back to the inflation pipe 102, so that the moving ball 402 moves excessively and drives the probe 406 to insert into the signal slot 405 to transmit an electric signal, thereby warning the stress state of the air rib air film 100.

[0046] In summary, the vortex sheet 300 uniformly constructed inside the inflation pipe 102 can guide the gas flowing through the inflation pipe 102 to inflate the gas rib air film 100 into spiral turbulent flow. This spiral turbulent flow form of gas flow is more smooth, compared with ordinary gas flow, can effectively reduce the resistance of gas flow in the pipeline, so that the gas can be more quickly and efficiently filled into the gas rib air film 100, shorten the inflation time, improve the inflation efficiency, after the gas enters the gas rib air film 100, the spiral rib 109 can continue to guide the gas flow to rotate, further reduce the filling resistance of the gas flow, ensure that the gas rib air film 100 can be quickly and uniformly inflated, the shaking rod 310 arranged inside the inflation pipe 102 can be hammered and vibrated, and the transmission assembly inside the gas exchange pipe 103 is used to push the shaking rod 310 to shake, which can apply a vibration force according to the flow of the gas flow. During the unfolding of the gas rib air film 100, there is static friction between the film surfaces. This vibration force can effectively reduce the static friction, making the unfolding of the gas rib air film 100 more smooth, while helping to release the stress in the folded area, reducing the damage to the film surface caused by stress concentration, and prolonging the service life of the gas rib air film 100. When snow covers the surface of the gas rib air film 100, the gravity of the snow will cause the gas rib air film 100 to be deformed under pressure, and then drive the gas flow. The gas flow will disturb the touch flow plate 305 to move, and through the transmission assembly, the shaking rod 310 will be applied to the gas exchange pipe 103 to shake. This shaking will be transmitted to the gas rib air film 100, causing the snow to slide off, avoiding excessive pressure on the gas rib air film 100 caused by too much snow, and ensuring the safety of the entire structure. When the gas rib air film 100 is subjected to an impact force outside the predetermined range, the excess gas flows back into the inflation pipe 102, causing the ball 402 to move excessively, driving the probe 406 to insert into the signal slot 405 to transmit an electrical signal, and warning the stress state of the gas rib air film 100. The operator can take timely measures according to the warning information, such as checking the damage of the gas rib air film 100, adjusting the inflation pressure, etc., to avoid damage to the gas rib air film 100 caused by excessive stress, and improve the safety and reliability of the entire structure.

[0047] Working principle: in use, by respectively inflating a single gas rib air film 100, then by pulling the rope through the hook rib 110 to fix the gas rib air film 100 on the top of the mounting plate 108, then inflating multiple gas rib air films 100 and using buckles to pass through the ring buckle 106 to assemble multiple gas rib air films 100;

[0048] When multiple gas rib air films 100 need to be moved, operate the multiple cylinders 205 to adjust the position of the positioning seat 204 to be away from the rail bar 200, operate the motor 203 to drive the roller 202 to rotate to move the mounting plate 108, thereby adjusting the position of the multiple gas rib air films 100, and when moved to the desired position, operate the cylinder 205 to drive the positioning seat 204 to move to be in contact with the rail bar 200, thereby completing the fixation;

[0049] In the process of inflation, first slowly start the blower 104 to gas into the gas pipe 101, gas through the gas cavity 112 and into the gas rib air film 100 through the inflation pipe 102, so that it slowly unfold, then increase the gas volume of the blower 104, and the gas will form a spiral flow when passing through the inflation pipe 102 into the gas rib air film 100, the gas will move along the guide of the spiral rib 109 to adhere to the inside of the gas rib air film 100, reducing the resistance of the airflow, while the airflow moving in the inflation pipe 102 will make the flow plate 305 shake, and then make the shaking block 302 move up and down, thereby driving the contact displacement frame 306 of the contact bead 303, the displacement frame 306 will continuously push the crank 307 to tilt and make one end of the crank 307 press the spring sheet 309, thereby storing power for the shaking rod 310, then in the reset process of the displacement frame 306, the shaking rod 310 hammers the inflation pipe 102 to make it shake, and the resonance force is transmitted to the gas rib air film 100;

[0050] When the gas rib air film 100 is full of gas, the internal gas pressure is stable, and when the gas rib air film 100 is extruded by external force, the gas in the gas rib air film 100 can flow back to the inside of the inflation pipe 102, so that the flexible pressure sheet 404 above the feedback column 400 is pushed down by the airflow, thereby driving the moving ball 402 to move in the movable cavity 401, and when the gas rib air film 100 is impacted by a predetermined external force, the excess gas flows back to the inflation pipe 102, so that the moving ball 402 moves excessively and drives the probe 406 to insert into the signal slot 405 to transmit an electrical signal, thereby warning the stress state of the gas rib air film 100.
