[0026] Embodiments of the present application are described below in detail with reference to the accompanying drawings, in which like or similar elements are denoted by like or similar reference numerals throughout the drawings. The embodiments described below are examples only, and are not to be construed as limiting the present application.

[0027] The layer-blocking pneumatic strut type of truss structure 100 according to embodiments of the present application is described below with reference to Figures 1-5 The layer-blocking pneumatic strut type of truss structure 100 according to embodiments of the present application is described below with reference to

[0028] This application proposes a rapid prototyping layered blockage air-supported tensioned wire structure 100, which includes an airbag 10, a layered blockage member 20, and a cable 30. The airbag 10 is adapted to be inflated and deflated to facilitate switching between a use mode and a storage mode. When inflated, the airbag 10 is adapted to seal the internal gas and withstand the internal air pressure. The layered blockage member 20 is disposed on the upper surface of the airbag 10. The cable 30 is tensioned and connected to the lower surface of the airbag 10. The layered blockage member 20 includes a vacuum bag 21 and flexible material members 22. The flexible material members 22 are disposed inside the vacuum bag 21, and the flexible material members 22 are constructed in multiple stacked configurations. The vacuum bag 21 is adapted to be evacuated or de-evacuated to facilitate changes in the stiffness of the layered blockage member 20. In a stiffened state, the layered blockage member 20 is adapted to withstand pressure and transmit the pressure to the airbag 10. The airbag 10 is adapted to provide elastic support for the layered blockage member 20.

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

[0030] According to the layered blocking air-supported tensioned structure 100 of this application, the airbag 10 can switch between a use mode and a storage mode by inflating and deflating. The use mode refers to the inflated form of the airbag 10, and the storage mode refers to the deflated and folded flexible form of the airbag 10. In the use mode, the airbag 10 has a certain degree of elasticity, which can maintain an internal seal to prevent internal gas leakage, withstand internal air pressure, and apply elastic support force to the layered blocking member 20.

[0031] According to the layer blocking member 20 of this application, such as Figure 2 As shown, the layered blocking member 20 includes a vacuum bag 21 and a flexible material component 22. The layered blocking member 20 can change its stiffness by evacuating and releasing the vacuum bag 21. Before evacuation, since both the vacuum bag 21 and the flexible material component 22 are flexible, the layered blocking member 20 is relatively soft and can be freely deformed and folded. After evacuation, a pressure difference is formed inside and outside the vacuum bag 21. The confining pressure generated by this pressure difference acts on the flexible material component 22, increasing the interlayer friction and shear resistance of the multilayer flexible material component 22, thereby increasing the bending stiffness of the layered blocking member 20 and achieving rigidification. The rigidified layered blocking member 20 can withstand pressure and transmit the pressure to the airbag 10. After releasing the vacuum, the layered blocking member 20 returns to its flexible state, making it easy to fold.

[0032] According to the cable 30 of the application, the cable 30 has the characteristics of light weight and flexibility, can simplify the anchoring structure and the installation process, can be folded and rolled together with the air bag 10 and the layer blocking member 20, can save storage space, is convenient for transportation and rapid construction; in addition, compared with the steel cable, the cable 30 is not easy to be affected by the environment, is not easy to be corroded and the like, has better durability, so that the layer blocking air support type string structure 100 of the application can be applied to the water surface, outdoor and the like. Moist environment.

[0033] According to the layer blocking air support type string structure 100 of the application, since the air bag 10, the layer blocking member 20 and the cable 30 all have the characteristics of light weight and flexibility, the whole layer blocking air support type string structure 100 of the application can be folded and unfolded, has light weight and is convenient for storage and transportation.

[0034] It should be noted that in the service stage of the layer blocking air support type string structure 100, the relationship between the stress of the layer blocking air support type string structure 100 and the slippage of the flexible material piece 22 is as shown in Figure 3 When the applied load is small, that is, the structure stress F satisfies F≤F1, the relative slippage does not occur between the flexible material pieces 22, the structure has high rigidity, and therefore the slope of the first segment is large; when the structure stress F satisfies F1<F≤F2, the relative slippage occurs between the flexible material pieces 22, the structure rigidity decreases, and with the increase of the number of slippage layers, the rigidity becomes smaller and smaller, therefore the slope of the second segment is lower than that of the first segment, in actual application, the second segment is not an ideal straight line, but a random broken line, and the second segment here only represents the trend; when the applied load is large, that is, the structure stress F satisfies F>F2, the slippage occurs between each layer of the flexible material pieces 22, that is, the complete relative slippage occurs, the structure rigidity is low, and the slope of the third segment is small, at this time, the layer blocking member 20 will have large deformation; at the same time, when the structure stress F satisfies F>F2, the bearing capacity of the structure reaches the limit, the stress basically does not change, the deformation of the layer blocking member 20 continuously increases, continuously consumes energy, and the load cannot be increased any more.

[0035] Based on the above characteristics, the layer blocking member 20 has energy dissipation capability. In the service stage of the layer blocking pneumatic strut type tensile structure 100, when the structure bears a larger dynamic load, the layer blocking member 20 will deform greatly, and the relative slip between the multi-layer flexible material pieces 22 will generate friction due to external force, so that energy can be dissipated through interlayer friction, and the structural response such as acceleration and structural deformation under dynamic load can be reduced, thereby improving the stability and reliability of the layer blocking pneumatic strut type tensile structure 100. In the process of overall deformation and energy dissipation of the layer blocking member 20, the lower air bag 10 provides continuous elastic support and is deformed under pressure. After the load is removed, the vacuum of the layer blocking member 20 is released to remove the restriction of the layer blocking member 20 on the air bag 10, so that the air bag 10 rebounds and the structural deformation is restored; in the process of rebounding the air bag 10, the air bag 10 can be inflated if necessary to improve its elastic performance. After the deformation of the layer blocking pneumatic strut type tensile structure 100 is restored, the layer blocking member 20 can be vacuumed again to restore the normal service state. The layer blocking pneumatic strut type tensile structure 100 of the present application has good dynamic performance and the energy dissipation process is reversible, and can be used for multiple moving cycles.

[0036] In addition, since the layer blocking member 20 and the air bag 10 are both controlled by air pressure, by adjusting the vacuum degree of the layer blocking member 20 and the air pressure of the air bag 10, the stiffness of the layer blocking pneumatic strut type tensile structure 100 can be adjusted; and the layer blocking member 20 and the air bag 10 can share a set of control system, which can simplify the operation process of building the layer blocking pneumatic strut type tensile structure 100, and also facilitate the use of an automatic control system to improve the automation degree of structure building. The control process of the layer blocking member 20 and the air bag 10 is reversible, the control method is simple, and the control speed is fast; based on this, the layer blocking pneumatic strut type tensile structure 100 of the present application can be quickly formed and constructed on site, and the structure construction, air pressure control and energy dissipation process are all reversible, and can be used for multiple cycles in situ or in displacement, which can improve the utilization rate of resources.

[0037] As shown in Figure 4 The cycle use process of the layer blocking pneumatic strut type tensile structure 100 according to the present application is as follows:

[0038] S1: the layer blocking air strut type string structure 100 is unfolded and flattened as a whole; S2: the air bag 10 is inflated and pressurized, and the cable 30 is tightened to generate a pre-tension stress, at this time the air bag 10 shows a use form, the shape of the layer blocking air strut type string structure 100 is basically determined, and the layer blocking member 20 is also completely unfolded; S3: the layer blocking member 20 is vacuumized, and after vacuumization, the layer blocking member 20 is rigidly formed, at this time the layer blocking air strut type string structure 100 is completed, and the structure has strong bearing capacity; S4: the layer blocking air strut type string structure 100 is put into use and starts to serve, and during the service stage of the structure, the layer blocking member 20 can be cyclically energy-dissipated through air pressure control; S5: for temporary structures, after the service is completed, the external load is removed and the layer blocking air strut type string structure 100 is softened by air pressure control, specifically, the vacuum of the layer blocking member 20 can be released first, then the air pressure in the air bag 10 is released, and then the layer blocking air strut type string structure 100 is folded and stored; or the air pressure in the air bag 10 can be released first, then the vacuum in the layer blocking member 20 is released, and then the layer blocking air strut type string structure 100 is folded and stored; at this time the air bag 10 shows a storage form; the layer blocking air strut type string structure 100 is folded and stored for reuse, and can be placed in a bag for transportation.

[0039] In addition, since the layer blocking air strut type string structure 100 of the present application is an inflatable structure with low density, it can also be used as a floating structure on water and an air raft, etc., for water transportation.

[0041] According to some embodiments of the present application, the flexible material piece 22 is configured as a fiber fabric. The fiber fabric refers to a light and 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 have friction characteristics in themselves, the surface of the fiber fabric has a high friction coefficient, so that a larger friction force is easily generated between the flexible material pieces 22 of the present embodiment, which can effectively improve the rigidity of the layer blocking member 20 in the rigid state, further improve the load 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 self-load of the structure.

Through the laminated plane connection, the stress of the air bag 10 can be more uniform, thereby making the stability of the layer blocking air strut type cable-strut structure 100 higher.

[0044] In some embodiments, the air bag 10 is made of single-layer or multi-layer film material. The air bag 10 can be made of multi-layer film material, which has multiple functional layers. Each functional layer can be made of a material with special functions to improve the performance of the air bag 10. The layers are bonded by adhesive.

In addition, the plurality of cables 30 are independent of each other, which can play an additional constraint effect, avoid affecting the balance and stability of the structure when any cable 30 loses the tensioning effect, and can improve the reliability of the structure.
