Roll-out structure/hurricane sheathing
A roll-out sheet of construction material has a plurality of slats, each with a shelf with a generally upward facing surface and a ledge with a generally downwardly facing surface. The plurality of slats are adjacent one another so that the ledge of one slat overlies the shelf of an adjacent slat. A load-bearing flexible film is secured to the plurality of slats on one side, the opposite sides of the slats from the flexible film are free allowing the slats to articulate relative to one another. The slats may have a longitudinal opening at least partially through, which is optionally filled with thermal and/or sound insulation, and/or load-bearing filler. The openings can also include a rib or support extending across the opening and bracing one side wall of the slat against the other. A securing tab can extend outward from one or more slats, shaped as a hoop, or having a through opening. When deployed, the roll-out sheet may be flat or have some angle or curvature.
1. A roll-out construction material comprising:
a plurality of slats, each having a body, a ledge extending from a first lateral end of the body and a shelf extending from a second lateral end opposite the first lateral end, the body comprising a top surface and a bottom surface, the ledge comprising a first upper surface and a first lower surface, the shelf comprising a second upper surface and a second lower surface, wherein the first upper surface of the ledge is substantially flush with the top surface of the body and the second lower surface of the shelf is substantially flush with the bottom surface of the body, and wherein, during the deployment of the construction material, two adjacent slats are aligned with one another such that the first lower surface of the ledge of one of the slats overlies the second upper surface of the shelf of the other of the slats; and
a flexible load-bearing film secured to the plurality of slats on one side thereof, the opposite sides of the slats from the flexible film being free whereby the slats articulate relative to one another,
wherein the plurality of slats are configured and dimensioned such that the roll-out material can be rolled into a substantially cylindrical shape prior to deployment of the roll-out material,
wherein at least one slat comprises an opening at least partially therethrough along a longitudinal axis transverse to a lateral axis joining the first lateral end and the second lateral end; and wherein the material further comprises a support disposed within the opening, the support comprising a first portion extending along a direction from the top surface to the bottom surface of the slat and a second portion substantially parallel to the bottom surface of the slat.
2. The construction material according to claim 1 , wherein certain of the slats are arranged side by side along a longitudinal axis transverse to a lateral axis joining the first lateral end and the second lateral end, with the junction of any two slats along the longitudinal axis arranged at an intermediate point along the length of a laterally adjacent slat.
3. The construction material according to claim 1 , wherein the opening is filled with a filler.
4. The construction material according to claim 3 , wherein the filler is load bearing.
5. The construction material according to claim 3 , wherein the filler material provides insulation against one or more of heat and sound.
6. The construction material according to claim 1 , wherein the rib or support is a support, the support being integrally formed with one side wall and bracing against the opposite side wall.
7. The construction material according to claim 1 , further comprising a securing tab extending outward from at least one slat.
8. The construction material according to claim 7 , wherein the securing tab has a through opening.
9. The construction material according to claim 1 , wherein the first lower surface of the ledge of a slat interfaces with the second upper surface of the shelf of an adjacent slat to hold the roll-out construction material in flat deployed configuration.
10. The construction material according to claim 1 , wherein the load-bearing flexible film comprises a biaxial nylon film.
11. The construction material according to claim 1 , wherein the load-bearing flexible film is self-sealing against punctures.
12. The construction material according to claim 1 , wherein the slats comprise one or more of plastic, metal, and wood material.
13. The construction material according to claim 1 , wherein each of said two adjacent slats comprises a through hole, the two through holes aligned with one another.
14. The construction material according to claim 13 , further comprising a securing line passing through the through holes for applying compression to the slats by tensioning the securing line.
15. The construction material according to claim 1 , wherein the ledge has a first height defined from the first upper surface to the first lower surface and the shelf has a second height defined from the second upper surface to the second lower surface, the first height being equal to the second height.
16. The construction material according to claim 15 , wherein the ledge comprises a first width defined from the first lateral end of the ledge to the second lateral end of the ledge and the shelf has a second width defined from the first lateral end of the shelf to the second lateral end of the shelf, the first width being equal to the second width.
