Structural wind protective system and method
View Patent ↗A system and method for protecting a structure from wind damage utilizes a netting 12 positioned over the roof of the structure and a plurality of ground anchors 16, 17 at least partially below ground level and spaced from the structure. A plurality of perimeter cables 18, 20, 34 are each spaced about a perimeter portion of a netting when deployed, and a plurality of tie-downs 22 each interconnect one of the plurality of perimeter cables to a respective one of the plurality of anchors.
1. A system for protecting a structure including a roof from wind damage, comprising:
a netting for positioning over the roof of the structure, the netting having a deployed position wherein a perimeter portion of the netting is spaced below the roof of the structure, and the netting having a storage position wherein a portion of the netting is in a roll adjacent a roof overhang;
a plurality of anchors each at least partially below ground level and spaced from the structure;
a plurality of perimeter cables each woven between strands of the perimeter portion of the netting, the plurality of perimeter cables including a low cable on one side of the structure and secured to the perimeter portion of the netting and a high cable on the one side of the structure and secured to the perimeter portion of the netting above the low cable; and
a plurality of tie-downs each extending between one of the plurality of anchors and the low cable when the netting is in the deployed position, and another plurality of tie-downs each extending between the high cable and the one of the plurality of anchors when the netting is in the deployed position.
2. A system as defined in claim 1 , further comprising:
a device for tensioning each of the plurality of tie-downs when the netting is in the deployed position.
3. A system as defined in claim 1 , wherein the netting is formed from a polyethylene material and has voids greater than about 3 inches.
4. A system as defined in claim 1 , wherein the plurality of perimeter cables are formed from a stainless steel cable.
5. A system as defined in claim 1 , further comprising:
a pair of ferrules each securing a cable loop to one of the strands of a perimeter portion of the netting; and
one of the plurality of tie-downs is secured to the cable loop when the netting is in the deployed position.
6. A system as defined in claim 1 , wherein the plurality of perimeter cables includes at least 3 vertically spaced perimeter cables.
7. A system as defined in claim 1 , wherein the plurality of anchors comprises an anchor spaced outward from each primary corner of the structure.
8. A system as defined in claim 1 , wherein a roof portion of the netting is positioned over the roof when the netting is in both the deployed position and the storage position, and the system further comprises:
a roll deployment device for releasing the roll of netting for deployment from the storage position to the deployed position.
9. A system as defined in claim 8 , wherein the roll deployment device consists of a daisy loop line which releases the wound roll when pulled.
10. A system as defined in claim 8 , further comprising:
a deployment line for releasing when the roll deployment device is deployed, such that the deployment line assists in the unrolling the wound roll of netting.
11. A system for protecting a structure including a roof from wind damage, the structure supported on a plurality of structure supporting pilings each extending above the ground level, the system comprising:
a netting for positioning over the roof of the structure, the netting having a deployed position wherein a perimeter portion of the netting is spaced below the roof of the structure, and the netting having a storage position wherein a portion of the netting is in a roll adjacent a roof overhang;
a plurality of anchors each at least partially below ground level and entirely spaced from the structure;
at least two perimeter cables each woven between strands of the perimeter portion of the netting;
a plurality of piling tie-downs each interconnecting a respective one of the at least two perimeter cables to a respective one said anchor of the plurality of structure supporting pilings when the netting is in the deployed position; and
a plurality of anchor tie-downs each interconnecting each of the at least two perimeter cables to one of the plurality of anchors.
12. A system as defined in claim 11 , wherein the at least one perimeter cable comprises:
a plurality of perimeter cables each about the perimeter portion of the netting when deployed, the plurality of perimeter cables including a low cable secured to the netting and a high cable secured to the perimeter portion of the netting above the low cable when the netting is in the deployed position.
13. A system as defined in claim 11 , further comprising:
a device for tensioning each of a plurality of anchor tie-downs, when the netting is in the deployed position.
14. A system as defined in claim 11 , wherein the netting is formed from a polyethylene material and has voids from about 3 inches to about 5 inches, and the plurality of tie-downs are each formed from stainless steel cable.
15. A system as defined in claim 11 , wherein a roof portion of the netting is positioned over the roof prior to deployment, and the perimeter portion of the netting is wound in a roll positioned adjacent said roof overhang in the storage position prior to deployment, and the system further comprises:
a roll deployment device for releasing the roll of netting for deployment.
16. A system as defined in claim 11 , wherein the plurality of anchors comprises an anchor spaced outward from each primary corner of the structure.
17. A system as defined in claim 11 , further comprising:
a pair of ferrules each securing a cable loop to one of the strands of a perimeter portion of the netting; and
one of the plurality of tie-downs is secured to the cable loop when the netting is in the deployed position.
