[0039] Embodiment 1

[0040] This embodiment provides an air membrane with a multi-layer cable net, so that the multi-layer cable nets are connected to each other, saving costs while making the multi-layer cable net have sufficient compressive strength. Figures 1 to 5As shown, an air membrane with multiple cable nets specifically includes a retaining wall 3, a first cable net layer 5, a second cable net layer 6 and a connecting buckle 4. The first cable net layer 5 is sleeved on the periphery of the air membrane, and the second cable net layer 6 is sleeved on the periphery of the first cable net layer 5 and interlaced with the first cable net layer 5. The first cable net layer 5 and the second cable net layer 6 both include a first direction cable 1 arranged along a preset first direction and a second direction cable 2 arranged along a preset second direction, and the first direction cable 1 and the second direction cable 2 are interlaced. It should be noted that the first direction is not parallel to the second direction and is not opposite, so that the first direction cable 1 and the second direction cable 2 are interlaced. Exemplarily, the first direction cable 1 and the second direction cable 2 are orthogonal, and the two orthogonal cable nets can share the load together, increase the stability and bearing capacity of the structure, which is particularly important for large-span, high-level air membranes. In this embodiment, a total of two layers of cable nets are provided. In other embodiments, the air membrane can also be more than two layers of cable nets. At this time, the connection structure between the two adjacent cable nets is similar to that between the two layers of cable nets in this embodiment.

[0041] Further, such as Figure 1 and Figure 2 As shown, Figure 2 In order to distinguish the first cable net layer from the second cable net layer, the first cable net layer 5 is represented by a dotted line, and the second cable net layer 6 is represented by a solid line. It should be noted that in actual implementation, the first directional cables 1 and the second directional cables 2 in the first cable net layer 5 and the second cable net layer 6 can be the same type of cables. The connecting buckles 4 are distributed at multiple intersections of the first directional cables 1 in the first cable net layer 5 and the second directional cables 2 in the second cable net layer 6, and at multiple intersections of the second directional cables 2 in the first cable net layer 5 and the first directional cables in the second cable net layer 6.

[0042] For the multiple intersections between the first directional cables 1 in the first cable net layer 5 and the second directional cables 2 in the second cable net layer 6, there are 1-4 intersections without the connection buckles 4 between the adjacent connection buckles 4, that is, the connection buckles 4 are set in a skipping manner. For the multiple intersections between the second directional cables 2 in the first cable net layer 5 and the first directional cables 1 in the second cable net layer 6, there are at least 1-4 intersections without the connection buckles 4 between the adjacent connection buckles 4, that is, the connection buckles 4 are also set in a skipping manner. When there are 5 or more intersections without the connection buckles 4 between two adjacent connection buckles 4 of the multi-layer cable net, the distance between the connection buckles 4 between the multi-layer cable nets is large due to the large distance between the cables of the large-span air film, which easily leads to insufficient load sharing between the multi-layer cable nets, affecting the stability of the air film. When there are 0 intersections without the connection buckles 4 between two adjacent connection buckles 4 of the multi-layer cable net, that is, when the connection buckles 4 are set continuously, it will lead to higher production costs. In addition, since the connection buckle 4 is generally made of metal and has a certain weight, it will increase the load of the cable net. It should be noted that the intersection of the connection buckle 4 is not set between two adjacent connection buckles 4, and the number of intersections is adjusted accordingly at 1-4. When the span of the air film is large, the distribution density of the connection buckle 4 can be increased.

[0043] In a specific embodiment, for multiple intersections between the first directional cables 1 in the first cable net layer 5 and the second directional cables 2 in the second cable net layer 6, there is one intersection without a connection buckle 4 between adjacent connection buckles 4; for multiple intersections between the second directional cables 2 in the first cable net layer 5 and the first directional cables 1 in the second cable net layer 6, there is also one intersection without a connection buckle 4 between adjacent connection buckles 4. In this case, it is suitable for most air membranes, and the loads shared by the multiple layers of cable nets can make the cable net have sufficient strength, and it can still remain stable under strong winds or extreme weather conditions, and there is no need to increase much cost.

[0044] In a specific embodiment, the first directional cable 1 and the second directional cable 2 are both connected to the retaining wall 3. Figure 3As shown, a pre-embedded anchor 10 of a net cable is preset on the retaining wall 3, and the pre-embedded anchor 10 of the net cable is fixed on the top of the retaining wall 3, and a fixing buckle 11 is arranged on the pre-embedded anchor 10 of the net cable. Specifically, a plurality of pre-embedded anchors 10 of net cables are arranged on the retaining wall 3, and each pre-embedded anchor 10 of the net cable is provided with a fixing buckle 11, and both ends of the first direction cable 1 and the second direction cable 2 are connected to the fixing buckle 11 on the pre-embedded anchor 10 of the net cable at the top of the retaining wall 3. That is to say, both ends of each cable are fixed on the retaining wall 3, so that the structure of the cable net is more stable and the compressive strength of the air film is increased. It should be noted that the first direction cable 1 and the second direction cable 2 in the first cable net layer 5 can be connected to the same fixing buckle 11, or one end of each cable can be connected to a fixing buckle 11 separately, and the first direction cable 1 and the second direction cable 2 in the second cable net layer 6 can be connected to the same fixing buckle 11, or one end of each cable can be connected to a fixing buckle 11 separately.

[0045] Further, a cable sleeve 13 is sleeved on one end of the first directional cable 1 and the second directional cable 2 connected to the retaining wall 3. Specifically, a cable sleeve ring 12 is provided on one end of the first directional cable 1 and the second directional cable 2 connected to the fixing buckle 11, which is used to connect with the fixing buckle 11. The cable sleeve 13 is used to fix the cable sleeve ring 12, so that the first directional cable 1 and the second directional cable 2 are more firmly fixed on the retaining wall 3.

[0046] In a specific embodiment, a photovoltaic device 14 for power generation is provided on the first cable net layer 5 and / or the second cable net layer 6. The photovoltaic device 14 is, for example, a solar panel. The photovoltaic device 14 converts solar radiation into electrical energy, utilizes renewable solar energy resources, reduces dependence on traditional energy, reduces consumption of fossil fuels, and is beneficial to environmental protection and sustainable development. In addition, the air membrane usually has a large roof area, which can be used to install the photovoltaic device 14. In this way, solar energy can be used to generate electricity, meet part or all of the electricity demand, achieve energy self-sufficiency, and reduce energy costs.

[0047] In a specific embodiment, the connecting buckle 4 is also located at the intersection of the first directional cable 1 and the second directional cable 2 in the first cable net layer 5 and the intersection of the first directional cable 1 and the second directional cable 2 in the second cable net layer 6. Specifically, each intersection of the first directional cable 1 and the second directional cable 2 in the first cable net layer 5 and each intersection of the first directional cable 1 and the second directional cable 2 in the second cable net layer 6 is provided with a connecting buckle 4, so that the structures of the first cable net layer 5 and the second cable net layer 6 are more stable and have strong pressure resistance.

[0048] In a specific embodiment, Figure 4 and Figure 5As shown, the connection buckle 4 includes a first buckle seat 7 and a second buckle seat 8, the first direction cable 1 is located in the first buckle seat 7, the second direction cable 2 is located in the second buckle seat 8, and the first buckle seat 7 and the second buckle seat 8 are fixedly connected by a fastener 9. Specifically, a cable groove is provided in each of the first buckle seat 7 and the second buckle seat 8. After the first direction cable 1 is installed in the cable groove in the first buckle seat 7 and the second direction cable 2 is installed in the cable groove in the second buckle seat 8, the first buckle seat 7 and the second buckle seat 8 are fixed by the fastener 9, so that the first direction cable 1 and the second direction cable 2 are fixedly connected.

[0049] In a specific embodiment, the first directional cables 1 are orthogonal to the second directional cables 2. The cable net formed by the orthogonally arranged first directional cables 1 and second directional cables 2 can effectively disperse external forces such as wind loads, enhance the stability and wind resistance of the structure, and make the air film safer and more reliable in harsh natural environments.

[0050] In a specific embodiment, the first direction rope 1 and the second direction rope 2 both include metal ropes or synthetic fiber ropes. Specifically, the metal rope is, for example, a steel rope. The steel rope has high strength and corrosion resistance, can withstand large tensile forces, and remains stable under harsh environmental conditions. At the same time, the steel rope also has a long service life and durability. The synthetic fiber rope is, for example, a carbon fiber rope. The carbon fiber has a very high tensile strength, so that the carbon fiber rope can withstand large tensile forces and remain stable. Compared with metal, the density of carbon fiber is smaller, so the carbon fiber rope is lighter, which helps to reduce the dead weight of the entire structure. The synthetic fiber rope can also be a polyamide fiber rope. Polyamide fiber is a high-strength, low-elongation synthetic fiber material. Polyamide fiber has a very high tensile strength and can withstand large tensile forces and remain stable. In addition, polyamide fiber has excellent durability and UV resistance, and maintains structural stability during long-term use.

[0051] In a specific embodiment, the first direction rope 1 and the second direction rope 2 are both formed by a plurality of sub-rope 15 spirally arranged in parallel. When arranged in parallel, a plurality of sub-rope can be formed synchronously and / or connected together through a connecting structure. In a specific embodiment, the first direction rope 1 and the second direction rope 2 are both formed by a plurality of sub-rope 15 spirally wound. The spiral winding design allows the tension of the rope to be evenly distributed over the entire structure, reducing the possibility of local stress concentration, and helping to improve the stability and safety of the structure. At the same time, the spiral winding design allows the rope to have a certain degree of flexibility, and can adapt to changes in structural shape within a certain range, thereby improving the applicability and flexibility of the structure. It should be noted that the sub-rope 15 can be a metal rope or a synthetic fiber rope.

[0052] The utility model is provided with connecting buckles 4 between the multiple layers of cable nets to connect the multiple layers of cable nets to each other. Meanwhile, two adjacent connecting buckles 4 are spaced apart by multiple cables, which saves costs while making the multiple layers of cable nets have sufficient compressive strength. The adjacent cable nets can share pressure, making it difficult for the cable nets to fall off, thereby improving the stability of the air film.

[0053] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the above embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
