[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 5 The layer-blocked gas-supported string structure 100 according to an embodiment of the present invention is described. The layer-blocked gas-supported string structure 100 of the present application is mainly used in extreme environments with a lack of resources, outdoor environments, etc., or temporary structures that need to be built quickly.

[0028] The present application proposes a rapid prototyping layer-blocking air-supported string-tensioned structure 100, which includes an airbag 10, a layer-blocking member 20 and a cable 30; the airbag 10 is suitable for being inflated and unfolded and deflated and folded so as to be suitable for switching between a use form and a storage form, and the airbag 10 is suitable for sealing the internal gas and bearing the internal air pressure when inflated and unfolded; the layer-blocking member 20 is arranged on the upper surface of the airbag 10; the cable 30 is tensioned and connected to the lower surface of the airbag 10; the layer-blocking member 20 includes a vacuum bag 21 and a flexible material piece 22, the flexible material piece 22 is arranged in the vacuum bag 21, and the flexible material piece 22 is constructed as a plurality of stacked pieces; the vacuum bag 21 is suitable for evacuating or releasing the vacuum so as to be suitable for the layer-blocking member 20 to undergo a change in stiffness; the layer-blocking member 20 is suitable for bearing pressure and transferring the pressure to the airbag 10 in a rigidified state, and the airbag 10 is suitable for providing elastic support to the layer-blocking member 20.

[0029] According to the layer-blocking air-supported string structure 100 of the present application, the layer-blocking air-supported string structure 100 includes an airbag 10, a layer-blocking member 20 and a cable 30. The layer-blocking member 20 replaces the upper pressure-bearing component of the traditional air-supported string structure, and the cable 30 replaces the steel cable of the traditional air-supported string structure.

[0030] According to the layer-blocking gas-supported string structure 100 of the present application, the airbag 10 can switch between a use state and a storage state by being inflated and deployed and deflated and folded. The use state refers to the deployed state of the airbag 10 after being inflated, and the storage state refers to the flexible state of the airbag 10 after being deflated and folded. The airbag 10 has a certain elasticity in the use state, can maintain internal sealing to prevent internal gas leakage, can withstand internal gas pressure and apply elastic support force to the layer-blocking member 20.

[0031] According to the layer blocking member 20 of the present application, Figure 2 As shown, the layer blocking member 20 includes a vacuum bag 21 and a flexible material piece 22. The layer blocking member 20 can change its stiffness by evacuating and releasing the vacuum bag 21. Before the vacuum is drawn, since both the vacuum bag 21 and the flexible material piece 22 have flexible characteristics, the layer blocking member 20 is relatively soft and can be deformed and folded freely. After the vacuum is drawn, a pressure difference will be formed inside and outside the vacuum bag 21. The confining pressure generated by the pressure difference between the inside and outside will act on the flexible material piece 22, so that the interlayer friction of the multi-layer flexible material piece 22 is increased, and the interlayer shear resistance is improved, thereby increasing the bending stiffness of the layer blocking member 20 and achieving rigidification and shaping. The rigidified layer blocking member 20 can withstand pressure and transfer the pressure to the airbag 10. After the vacuum is released, the layer blocking member 20 returns to a flexible state, which is convenient for folding.

[0032] According to the cable 30 of the present application, the cable 30 is lightweight and flexible, can simplify the anchoring structure and the installation process, can be rolled up and folded as a whole with the airbag 10 and the layer blocking member 20, can save storage space, and is convenient for transportation and rapid construction; in addition, compared with steel cables, the cable 30 is not easily affected by the environment, is not prone to corrosion, etc., and has better durability, so that the layer blocking air-supported string structure 100 of the present application can be used in humid environments such as water surfaces and outdoors.

[0033] According to the layer-blocking gas-supported string structure 100 of the present application, since the airbag 10, the layer-blocking member 20 and the cable 30 are all light and flexible, the whole layer-blocking gas-supported string structure 100 of the present application can be folded and unfolded, and the structure is light and convenient for storage and transportation.

[0034] It should be noted that, during the service period of the layer-blocked air-supported string structure 100, the relationship between the force of the layer-blocked air-supported string structure 100 and the slippage of the flexible material piece 22 is as follows: Figure 3 As shown in the figure, F represents the force of the layer-blocked air-supported string structure 100, and S represents the displacement of the multi-layer flexible material piece 22. When the applied load is small, that is, the structural force F satisfies F≤F1, no relative slip occurs between the flexible material pieces 22, and the structural stiffness is high, so the slope of the first line segment is large; when the structural force F satisfies F1<F≤F2, partial relative slip occurs between the flexible material pieces 22, the structural stiffness decreases, and as the number of sliding layers increases, the stiffness becomes smaller and smaller, so the slope of the second line segment is lower than the first segment. In actual applications, the second segment is not an ideal straight line, but a random broken line. The second line segment here only represents a trend; when the applied load is large, that is, the structural force F satisfies F>F2, slip occurs between each layer of the flexible material pieces 22, that is, complete relative slip occurs, the structural stiffness is low, and the slope of the third line segment is small. At this time, the layer blocking component 20 will undergo a large deformation; at the same time, when the structural force F satisfies F>F2, the bearing capacity of the structure reaches its limit, the force remains basically unchanged, the deformation of the layer blocking component 20 continues to increase, and energy is continuously consumed, and the load cannot be further increased.

[0035] Based on the above characteristics, the layer blocking member 20 has energy dissipation capability. During the service stage of the layer blocking gas-supported string structure 100, when the structure is subjected to a relatively large dynamic load, the layer blocking member 20 will be greatly deformed, and the multi-layer flexible material pieces 22 will slide relative to each other due to external forces to generate friction. Energy can be consumed through inter-layer friction, reducing the structural response under dynamic loads, such as acceleration and structural deformation, and improving the stability and reliability of the layer blocking gas-supported string structure 100. During the process of overall deformation and energy dissipation of the layer blocking member 20, the lower airbag 10 provides continuous elastic support and is deformed under pressure. After the load is unloaded, the layer blocking member 20 can release the vacuum to release the vacuum, so that the layer blocking member 20 can release the restrictive effect on the airbag 10, so that the airbag 10 rebounds and the structural deformation is restored; in the process of making the airbag 10 rebound, the airbag 10 can be inflated if necessary to improve its elastic performance. After the deformation is restored, the layer blocking gas-supported string structure 100 can be restored to a normal service state by extracting the vacuum from the upper layer blocking member 20 again. The layer-blocking air-supported string structure 100 of the present application has good dynamic performance and a reversible energy consumption process, and can be moved and used in cycles for multiple times.

[0036] In addition, since both the layer blocking member 20 and the airbag 10 are controlled by air pressure, the stiffness of the layer blocking air-supported string structure 100 can be adjusted by adjusting the vacuum degree of the layer blocking member 20 and the air pressure of the airbag 10; and the layer blocking member 20 and the airbag 10 can share a set of control systems, which can simplify the operation process of building the layer blocking air-supported string structure 100, and also facilitate the use of an automated control system to improve the degree of automation of structure construction. The control process of the layer blocking member 20 and the airbag 10 is reversible, the control method is simple, and the control speed is fast; based on this, the layer blocking air-supported string structure 100 of the present application can be quickly formed and constructed on site, and the structure construction, air pressure control, and energy consumption process are all reversible, and can be recycled multiple times in situ or shifted, which can improve the utilization rate of resources.

[0037] like Figure 4 As shown, the recycling process of the layer-blocking air-supported string structure 100 according to the present application is as follows:

[0038] S1: unfold and flatten the layer-blocking air-supported string-tensioned structure 100 as a whole; S2: inflate and pressurize the airbag 10, tighten the cable 30 to generate pre-tension stress, at this time the airbag 10 is in use, the shape of the layer-blocking air-supported string-tensioned structure 100 is basically finalized, and the layer-blocking component 20 is also fully unfolded; S3: evacuate the layer-blocking component 20, after the vacuum is drawn, the layer-blocking component 20 is rigidified, at this time the layer-blocking air-supported string-tensioned structure 100 is completed, and the structure has a strong bearing capacity; S4: put the layer-blocking air-supported string-tensioned structure 100 into use and start service, during the service stage of the structure, the layer-blocking component 20 can be controlled by air pressure to consume energy in a cycle. ; S5: For temporary structures, after the service is over, the external load is removed and the layer-blocking gas-supported string-tensioned structure 100 is softened by air pressure control. Specifically, the vacuum of the layer-blocking component 20 can be released first, and then the air pressure inside the airbag 10 can be released, and then the layer-blocking gas-supported string-tensioned structure 100 can be folded and stowed; or while keeping the vacuum of the layer-blocking component 20, the air pressure inside the airbag 10 can be released first, and then the vacuum in the layer-blocking component 20 can be released, and then the layer-blocking gas-supported string-tensioned structure 100 can be folded and stowed; at this time, the airbag 10 is in a storage form; the layer-blocking gas-supported string-tensioned structure 100 is folded and rolled up and stored for reuse, and can be placed in a bag for easy transportation during storage.

[0039] In addition, since the layer-blocked air-supported string structure 100 of the present application is an inflatable structure with a low density, it can also be used as a floating structure and an air raft for water transportation. The layer-blocked air-supported string structure 100 of the present application has a wide range of uses and has a good application prospect.

[0040] The layer-blocking gas-supported string-tensioned structure 100 according to the present application has the following advantages: first, the layer-blocking gas-supported string-tensioned structure 100 is lightweight and foldable as a whole, and is easy to transport; second, the layer-blocking member 20 and the airbag 10 are controlled by air pressure, and the control process is simple and the control speed is fast, so that the construction process of the layer-blocking gas-supported string-tensioned structure 100 is simple and efficient, including two main steps of inflating and unfolding the airbag 10 and vacuuming and rigidifying the layer-blocking member 20. No additional on-site materials are required for construction, which is convenient for improving the degree of automation of control; third, the stiffness change of the layer-blocking member 20 and the airbag 10 is The whole process is reversible and can be recycled multiple times in situ or displaced, which can improve the utilization rate of resources; fourth, the cable 30 is used instead of the traditional steel cable, which is lighter, simpler to anchor, and has better durability in humid environments such as water surfaces and outdoors; fifth, the deformation of the layer blocking member 20 can generate friction energy consumption, the structure has good dynamic performance and the energy consumption process is reversible, and can be used for a long time or multiple times; sixth, the layer blocking air-supported string structure 100 of the present application has a wide range of uses and can be used in a variety of scenarios. It can be applied to a variety of environments including water environments and has good application prospects.

[0041] According to some embodiments of the present application, the flexible material piece 22 is constructed as a fiber fabric. The fiber fabric refers to a lightweight flexible product composed of fiber materials and yarns interwoven. Since the fiber materials and yarns are arranged in multiple directions and interwoven with each other, the fiber materials and yarns themselves have friction characteristics, and the fiber fabric surface has a high friction coefficient. Therefore, it is easy to generate a large friction force between the flexible material pieces 22 of this embodiment, which can effectively improve the rigidity of the layer blocking member 20 in the rigid state, further improve the bearing capacity of the structure, and improve the stability of the structure. At the same time, the fiber fabric has high flexibility and light weight, which can improve the deformation effect of the layer blocking member 20 and reduce the load of the structure itself.

[0042] In some embodiments, the airbag 10 is configured in a semi-cylindrical or rectangular parallelepiped shape, and the layer blocking member 20 is in a plate shape after being rigidified.

[0043] According to some embodiments of the present application, a first connection surface is formed on the top of the airbag 10, and a second connection surface is formed on the bottom of the layer blocking member 20, and the first connection surface is connected with the second connection surface in a close fit. In this embodiment, the layer blocking member 20 is disposed above the airbag 10, and the layer blocking member 20 and the airbag 10 are connected through a close fit plane. When the layer blocking gas-supported string structure 100 is subjected to a load, the layer blocking member 20 is subjected to force and transmits the pressure to the airbag 10. Through the close fit plane connection, the force on the airbag 10 can be made more uniform, thereby making the layer blocking gas-supported string structure 100 more stable.

[0044] In some embodiments, the airbag 10 is made of a single-layer or multi-layer film material. The airbag 10 can be made of a multi-layer film material with multiple functional layers, each of which can be made of a material with special functions to improve the performance of the airbag 10. The layers are bonded with adhesives, and the material and quantity of the specific functional layers can be increased or decreased according to the requirements of the use conditions and environment.

[0045] According to some embodiments of the present application, the cable 30 is constructed as an aramid fiber member. In this embodiment, the cable 30 is made of aramid fiber material, which is lighter and has good flexibility and durability, so that the cable 30 is easy to anchor and can be used for a long time in humid environments such as water surface and outdoors; it is also convenient to fold and roll up with the airbag 10 and the layer blocking member 20 for easy transportation and rapid construction.

[0046] According to some embodiments of the present application, the cable 30 is detachably connected to the airbag 10 or the layer blocking member 20. In this embodiment, the cable 30 is detachably connected to the airbag 10 or the layer blocking member 20, which is convenient for disassembly and replacement, and can improve the durability and repairability of the layer blocking gas-supported string structure 100.

[0047] According to some embodiments of the present application, a lock is provided on the cable 30, and a matching portion is formed on the airbag 10 or the layer blocking member 20, and the lock is detachably connected to the matching portion. In this embodiment, the cable 30 is connected to the airbag 10 or the layer blocking member 20 through the lock, and the lock matches the matching portion, making the removal of the cable 30 more convenient and quick, and the matching portion can also be used for anchoring or connecting with other components, so as to facilitate the parallel connection and combination of multiple layer blocking gas-supported string structures 100.

[0048] According to some embodiments of the present application, the cables 30 are constructed in multiple configurations, and the multiple cables 30 are staggered and stretched on the lower surface of the airbag 10. In this embodiment, the multiple cables 30 are staggered and stretched on the lower surface of the airbag 10, so that the cables 30 can provide greater pre-tension stress, making the balance of the internal force of the layer-blocked gas-supported string structure 100 more stable; and more constraints are formed on the airbag 10, which can improve the stability of the structure during the service stage. In addition, the multiple cables 30 are independent of each other, which can play an additional constraint effect, avoiding any cable 30 from affecting the balance and stability of the structure after losing the tensioning effect, and can improve the reliability of the structure.

[0049] According to some embodiments of the present application, the layer-blocking air-supported string structure 100 is suitable for connecting with one or more other layer-blocking air-supported string structures 100, and multiple layer-blocking air-supported string structures 100 can be used in parallel. In this embodiment, multiple layer-blocking air-supported string structures 100 are arranged in parallel along the width direction, and every two adjacent airbags 10 are connected, and every two adjacent layer-blocking members 20 are connected, such as Figure 5 As shown. In this embodiment, by setting a plurality of layer-blocking air-supported string structures 100 and connecting them in parallel along the width direction, the width of the layer-blocking air-supported string structure 100 can be widened, its bearing capacity and bearing area can be improved, and the application scope of the layer-blocking air-supported string structure 100 can be further expanded. Specifically, since a plurality of layer-blocking components 20 are connected in parallel, a force-bearing plate with a large area can be formed after rigidification, and a plurality of air bags 10 can provide a higher and more stable supporting force. The layer-blocking air-supported string structure 100 of the present application can be used as a floating structure, such as a floating platform on water, an air raft or other water transportation vehicles, and applied to a water environment. In this scenario, a plurality of air bags 10 can also provide a more stable buoyancy for the structure, which can ensure the practicality and reliability of the structure. In addition, the layer-blocking air-supported string structure 100 of this embodiment can also be used as a building structure such as a roof panel and a bridge panel.

[0050] In addition, the layer-blocking air-supported string-tensioning structure 100 is flexibly designed, and the number of the layer-blocking air-supported string-tensioning structures 100 can be flexibly selected and adjusted according to the usage scenarios and needs; when the layer-blocking air-supported string-tensioning structures 100 are used in parallel, any group of the layer-blocking air-supported string-tensioning structures 100 can be disassembled and replaced, which can further improve the durability and repairability of the parallel structure.

[0051] According to some embodiments of the present application, when multiple layer-blocking gas-supported string structures 100 are connected, multiple airbags 10 are connected by cables, and multiple layer-blocking components 20 are connected by connectors. In this embodiment, multiple airbags 10 are connected by cables 30, and the original cable 30 matching structure of each layer-blocking gas-supported string structure 100 can be directly applied without setting up a separate connection matching mechanism, and the cables 30 are easy to connect and operate, which can simplify the construction process. Multiple airbags are connected by cables, and multiple layer-blocking components are connected by connectors, which can improve the stability and reliability of the parallel structure.

[0052] According to some embodiments of the present application, for structures that need to further improve structural strength or are used for a long time, resin can be introduced into the vacuum bag 21 of the layer blocking member 20, and the flexible material piece 22 is suitable for being cured into one with the resin to form a composite plate. The layer blocking air-supported string structure 100 of this embodiment is mainly used in scenes that need to be in long-term service or have high requirements for structural strength. When used specifically, after the layer blocking member 20 has adjusted its shape, by introducing resin into the vacuum bag 21, the flexible material piece 22 can be cured into one with the resin to form a lightweight and high-strength composite material plate, and the layer blocking member 20 is transformed into a permanently formed rigid member with high structural strength, high bearing capacity, long-term stability, and the ability to carry large loads and be used for a long time. The layer blocking air-supported string structure 100 of this embodiment improves the applicability of the structure and has a wide range of applications. It can be applied to civil engineering, automated construction, rapid construction, smart skin, machinery, aerospace, robotics and other fields.

[0053] Furthermore, the airbag 10 can be inflated at any time to supplement the internal air pressure, thereby ensuring the supporting effect of the airbag 10 and improving the long-term performance of the layer-blocking gas-supported string structure 100.
