[0002] Many large-span roofs of stadiums adopt saddle-shaped shapes + small arch-supported membrane roofs. When the large-span saddle-shaped roofs of stadiums adopt cable net structures, the load-bearing cables / stabilizing cables are mostly arranged in a spoke-like manner. Rainwater flows from the outer ring high area to the inner ring high area, then from the inner ring high area to the inner ring low area, and finally from the inner ring low area to the outer ring low area and enters the rain gutter. Therefore, the drainage pipes are concentrated in the outer ring low area, which has a great impact on the architectural effect and is prone to cause rainwater collection, such as poor drainage. In addition, this drainage design cannot achieve natural drainage in areas with relatively flat roofs, and special drainage pipes need to be set up below the area. When the drainage pipes under the roof are located above the audience seats, it has a great impact on the architectural effect. Summary of the invention

[0027] Please refer to Figure 1-Figure 3The present embodiment provides a double-layer orthogonal large-opening cable net structure, comprising an upper orthogonal cable net 1, a lower orthogonal cable net 2, an outer pressure ring beam 3, an inner ring beam 4, a folding membrane assembly, and a plurality of connecting assemblies arranged along the Y axis. The upper orthogonal cable net 1 and the lower orthogonal cable net 2 are both stretched between the outer pressure ring beam 3 and the inner ring beam 4, and the upper orthogonal cable net 1 is located directly above the lower orthogonal cable net 2. The upper orthogonal cable net 1 and the lower orthogonal cable net 2 are both composed of a plurality of orthogonal cables distributed along the X axis and the Y axis, and the orthogonal cables on the upper orthogonal cable net 1 correspond one to one to the orthogonal cables on the lower orthogonal cable net 2. Each The connecting components all include a plurality of V-shaped connecting rods 5 connected in sequence along the X-axis, the inflection point of the V-shaped connecting rod 5 is connected to the first orthogonal cable 2-1 on the lower orthogonal cable net 2, and the two ends of the V-shaped connecting rod 5 are respectively connected to the two adjacent third orthogonal cables 1-2 of the second orthogonal cable 1-1 on the upper orthogonal cable net 1 corresponding to the first orthogonal cable 2-1. The folding surface membrane assembly includes a plurality of folding surface membranes 6, and the folding surface membranes 6 are laid above two adjacent V-shaped connecting rods 5 along the Y-axis direction. The V-shaped connecting rod 5 and the corresponding folding surface membranes 6 on the V-shaped connecting rod 5 together constitute a plurality of V-shaped drainage ditches parallel to the Y-axis.

[0028] By adopting a double-layer orthogonal large-opening cable net structure, the upper and lower double-layer orthogonal cable nets are connected by a V-shaped connecting rod 5. At the same time, by laying the folding membrane 6 on the erected cable net structure, a V-shaped drainage ditch extending along the Y-axis direction is formed, so that rainwater is directly discharged from the high area of ​​the roof to the outer ring low area, and there is no need to set a drainage pipe below the roof. The structural form fits the building shape closely, and the architectural effect is guaranteed.

[0029] Specifically, the upper orthogonal cable net 1 and the lower orthogonal cable net 2 are both composed of a plurality of orthogonal cables distributed along the X-axis and the Y-axis, wherein the X-axis and the Y-axis are two directions perpendicular to each other on the horizontal plane, and the orthogonal cables include but are not limited to load-bearing cables or stabilizing cables, and the orthogonal cables on the upper orthogonal cable net 1 correspond one-to-one to the orthogonal cables on the lower orthogonal cable net 2 in the height direction.

[0030] The double-layer orthogonal large-opening cable net structure includes a plurality of connecting components arranged along the Y-axis, and each of the connecting components includes a plurality of V-shaped connecting rods 5 connected in sequence along the X-axis. Since the lengths of the double-layer orthogonal large-opening cable net structure along the Y-axis are different, the number of V-shaped connecting rods 5 contained in each of the connecting components may be different.

[0031] In this embodiment, combined with Figure 3The inflection point of the V-shaped connecting rod 5 is connected to the first orthogonal cable 2-1 on the lower orthogonal cable net 2, and the two ends of the V-shaped connecting rod 5 are respectively connected to the two adjacent third orthogonal cables 1-2 of the second orthogonal cable 1-1 on the upper orthogonal cable net 1 corresponding to the first orthogonal cable 2-1, the second orthogonal cable 1-1 is located directly above the first orthogonal cable 2-1, and the two third orthogonal cables 1-2 are respectively located on both sides of the second orthogonal cable 1-1, and multiple V-shaped connecting rods 5 are connected sequentially along the X-axis, and at the same time, multiple V-shaped connecting rods 5 are evenly spaced in the Y-axis direction.

[0032] In this embodiment, the orthogonal cable is connected to the V-shaped connecting rod 5 via a cable clamp.

[0033] Further, the V-shaped connecting rod 5 is a cable member or a rod member. That is to say, the V-shaped connecting rod 5 can be a cable member with a certain flexibility made of the same material as the orthogonal cable, or a rigid cable member, and the present application does not impose any limitation on this.

[0034] The folding membrane assembly includes a plurality of folding membranes 6, and the folding membranes 6 are laid above two adjacent V-shaped connecting rods 5 along the Y-axis direction. The V-shaped connecting rods 5 and the corresponding folding membranes 6 on the V-shaped connecting rods 5 together form a plurality of V-shaped drainage ditches parallel to the Y-axis. By laying the folding membranes 6 on the set V-shaped connecting rods 5, a V-shaped drainage ditch extending along the Y-axis direction is formed, so that rainwater is directly discharged from the high area of ​​the roof to the low area of ​​the outer ring, and there is no need to set a drainage pipe below the roof range, which not only solves the drainage problem of the roof, but also ensures a better building effect.

[0035] In the present embodiment, the material of described folding membrane 6 is glass fiber.The membrane material that is used for building membrane structure can be roughly divided into PVC membrane, PTEF membrane and ETFE membrane according to coating material difference, and the correct selection of membrane material should consider the comprehensive factors such as the scale, purpose, form, service life and budget of its building and decide.PVC membrane is all cheaper than PTFE membrane in material and processing, and has the advantage of soft material, easy construction, but is poorer than PTFE membrane in performances such as strength, durable life, fire resistance.PTFE membrane is on superfine glass fiber fabric, is coated with the material that polytetrafluoroethylene resin forms, and the maximum micro-feature of PTFE membrane is exactly that durability, fire resistance and antifouling property are high.ETFE is the toughest fluoroplastic, and it keeps the good heat-resistance, chemical resistance and electrical insulation performance of PTFE, and radiation resistance and mechanical property have improvement to a great extent, and tensile strength can reach 50MPa, close to 2 times of polytetrafluoroethylene.

[0036] In this embodiment, the folding surface membrane 6 can be fixed on the V-shaped connecting rod 5 by a membrane clip, and adjacent folding surface membranes 6 need to be spliced ​​to prevent rainwater leakage.

[0037] In this embodiment, the double-layer orthogonal large-opening cable net structure is similar to a saddle shape, and the heights of the external pressure ring beam 3 are different at different locations.

[0038] Furthermore, the outer pressure ring beam 3 is provided with an annular drainage channel connected with the V-shaped drainage ditch along the circumferential direction. When the heights of the outer pressure ring beam 3 are not uniform, the annular drainage channel can facilitate the rainwater in the outer ring high area to flow naturally to the outer ring low area when the rainwater enters the outer ring area, so as to collect the rainwater in the outer ring area, avoid the need to set drainage pipes under each part of the outer pressure ring beam 3, and improve the aesthetics of the building.

[0039] Furthermore, a rain gutter is provided at the lowest point of the annular drainage channel. The rain gutter has a rectifying grille device, which can quickly drain rainwater from the roof. The grille has a rectifying effect to avoid the formation of excessively large vortices. At the same time, the grille of the rain gutter can block larger books and other debris, so as not to cause blockage in the drain pipe.

[0040] In this embodiment, the inner ring beam 4 can be a ring cable structure or a rigid truss structure, and this application does not limit this. Compared with a rigid truss, the inner ring using a cable has a simpler structure, while the rigid truss has better stress performance, higher strength and stiffness.

[0041] In summary, the embodiment of the present invention provides a double-layer orthogonal large-opening cable net structure. By adopting the double-layer orthogonal large-opening cable net structure, the upper and lower double-layer orthogonal cable nets are connected by a V-shaped connecting rod, and at the same time, by laying the folded membrane on the erected cable net structure, a V-shaped drainage ditch extending along the Y-axis direction is formed, so that rainwater is directly discharged from the high area of ​​the roof to the outer ring low area, and there is no need to set a drainage pipe below the surface within the roof range. The structural form fits the architectural shape closely, and the architectural effect is guaranteed.
