[0015] 1. The air-supported membrane structure of this utility model, which combines longitudinal and transverse cables with cross cables, can more effectively concentrate the main load and achieve uniform load transfer by mixing the main load-bearing cables and the tree-shaped cross cable net.

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, the air-supported membrane structure of the present invention, which is a cable net structure combining longitudinal and transverse cables and cross cables.
[0025] For easier understanding, please refer to Figure 1 This utility model provides an embodiment of an air-supported membrane structure with a combination of longitudinal and transverse cables and cross cables. The cable net structure adopts a mixed arrangement of longitudinal and transverse cables and cross cables in the building plan direction, wherein a number of main load-bearing cables 1 are set in the first axis and a tree-shaped cross cable net 2 is set in the second axis.
[0026] The tree-shaped cross cable net 2 is composed of at least two sets of load-bearing cables 21 and auxiliary cables 22 that cross at acute angles;
[0027] The main load-bearing cable 1 and the tree-shaped intersecting cable net 2 form a spatial grid through adjustable connectors 4. In some embodiments, when the first axis is the building width direction and the second axis is the building length direction, the main load-bearing cable 1 is arranged along the short side of the building. When the first axis is the building length direction and the second axis is the building width direction, the main load-bearing cable 1 is arranged along the long side of the building.
[0028] It should be noted that several main load-bearing cables 1 are set along the first axis (e.g., the width of the building), with a cable strength 1.2 to 2 times that of the tree-shaped intersecting cable net 2, to concentrate the main load. The main load-bearing cables 1 are arranged symmetrically along the short or long side axis of the building, suitable for trapezoidal, polygonal, and other irregularly shaped planes, enhancing the overall structural stability. The tree-shaped intersecting cable net 2, especially with at least two sets of acute-angle intersecting load-bearing cables 21 and secondary cables 22 along the second axis, forms a tree-like branching structure. The intersection angle is dynamically optimized according to the building load distribution, and a three-dimensional spatial grid is formed with the main load-bearing cables 1 through adjustable connectors 4, achieving uniform load transfer and enhancing the stability of the entire structure.
[0029] The node connector 3 is made of high-strength alloy steel. The intersection of the main load-bearing cable 1 and the crossing cables is fixed through this connector, ensuring bidirectional force transmission and anti-slip performance at the node. The adjustable connector 4 adopts a three-dimensional universal joint structure, with an adjustment angle range of ±15° to accommodate construction errors and deformation compensation under dynamic loads. Locking bolts are installed inside the connector, and the angle is fixed by pre-tightening after adjustment.
[0030] When the first axis is the width direction of the building, the second axis is the length direction of the main building, and the main load-bearing cable 1 is arranged along the short side of the building; conversely, if the first axis is the length direction of the building, the main load-bearing cable 1 is arranged along the long side.
[0031] In some embodiments, the main load-bearing cable 1 is provided with a connecting steel cable 6, and the intersection of the main load-bearing cable 1 and the connecting steel cable 6 with the intersection of the load-bearing cable 21 and the auxiliary cable 22 are all fixed by a node connector 3.
[0032] It should be noted that the main load-bearing cable 1 is equipped with connecting steel cables 6, and the intersection points of these cables are fixed to the intersection points of the load-bearing cable 21 and the secondary cable 22 through node connectors 3, which improves the rigidity of the overall structure.
[0033] In some embodiments, the adjustable connector 4 is a universal joint connector with three-dimensional rotational freedom, and its connection angle adjustment range is ±15°.
[0034] It should be noted that the adjustable connector 4 is a universal joint connector with three-dimensional rotational freedom, allowing an angle adjustment range of ±15° to adapt to different installation conditions.
[0035] The building plan is trapezoidal or polygonal, and the main load-bearing cable 1 is arranged along the axis of symmetry of the irregular plane.
[0036] It should be noted that for irregularly shaped building plans such as trapezoids or polygons, the main load-bearing cable 1 is arranged along the axis of symmetry of the irregular plan to ensure uniform force distribution.
[0037] The ratio of the steel cable strength of the main load-bearing cable 1 to the tree-shaped intersecting cable net 2 is 1.2:1 to 2:1.
[0038] It should be noted that the ratio of the steel cable strength of the main load-bearing cable 1 to the tree-shaped intersecting cable net 2 is set between 1.2:1 and 2:1 to ensure the safety factor of the structure.
[0039] The tree-shaped intersecting cable net 2 and the main load-bearing cable 1 are reinforced with reinforcing cables 5 in the building area.
[0040] It should be noted that by adding reinforcing cable 5, the local compressive strength and stability are further improved.
[0041] Working principle: First, in the building plan, the main load-bearing cable 1 and the tree-shaped intersecting cable net 2 adopt a mixed arrangement. The main load-bearing cable 1 is arranged along the symmetrical axis of the building's short or long side, depending on whether the building's primary axis is the width or length direction. This arrangement can effectively concentrate the main load and is suitable for irregularly shaped planes such as trapezoids and polygons, enhancing the overall stability of the structure.
[0042] Secondly, the tree-shaped intersecting cable net 2 consists of at least two sets of load-bearing cables 21 and auxiliary cables 22 intersecting at acute angles, forming a tree-like branching structure. The intersection angle is dynamically optimized according to the building load distribution, ensuring that the load can be uniformly transmitted in the three-dimensional spatial grid. Through adjustable connectors 4, these cable nets and the main load-bearing cables 1 form a stable spatial grid structure, achieving bidirectional force transmission and anti-slip performance.
[0043] Furthermore, the design of the node connector 3 and the adjustable connector 4 is crucial to the stability and adaptability of the entire structure. The node connector 3 is made of high-strength alloy steel, ensuring a firm connection at the junction; while the adjustable connector 4 uses a universal joint connector with three-dimensional rotational freedom, allowing an angle adjustment range of ±15° to accommodate construction errors and deformation compensation under dynamic loads.
[0044] Finally, the reinforcement of cable 5 further enhances the compressive strength and stability of the local area.
[0045] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
