Flood wall protection system

Abstract

A flood protection system comprises a plurality of stackable planks which mount at their ends to a building wall with a water tight seal. The wall mount includes a flat gasket portion directly affixed to the building and outwardly extending protrusions having a substantially T-shaped configuration located thereon such that a uniquely shaped gasket connected to a plank engages the substantially T-shaped outer portion of the protrusions to permit rapid stacking and disassembly of planks. The extruded aluminum planks include internal ribbing to provide added strength while eliminating the excessive weight of conventional planks. Unique anchor means may also be provided to stabilize the planks where long spans are involved.

DETAILED DESCRIPTION OF THE INVENTION

(8) This invention relates to a flood wall protection system to protect building openings from intrusion of flood waters. As shown in FIG. 1 the invention comprises a plurality of elongated stacked planks 10, 20 and 30 which are affixed at their ends to a wall mount 11, The hollow planks 10, 20 and 30 are of a unique design with structural ribbing 13 located between inner and outer faces 14, 15. The ribbing 13 runs between the faces 14 and 15 in a saw-tooth pattern with a cross-rib 16 where the saw tooth pattern engages the opposite face. This design, preferably of aluminum, is structurally stronger than prior art planks and able to withstand more lateral impact for its size. The reduced thickness of the planks 10, 20 and 30 eliminates excessive weight and facilitates handling and storage. For flexibility, the planks may be either 6 inches or 12 inches in width and formed to a required length.

(9) The bottom cross plank 10 engages a gasket 17 with its extensions 41 which extend along the surface of the opening 11 to form a water-tight seal. The cross plank 10 also engages a gasket 18 along its upper surface between extensions 42 to form a seal with the stacked middle cross plank 20. Normally an installation would include several middle cross planks 20 to provide height to the barrier.

(10) A middle cross plank includes a similar gasket 18 running along its upper surface between extensions 43 to provide a seal with the next stacked middle cross plank 20. Finally, a top cross plank 30 is mounted atop the gasket 18 of the highest plank. 20 to form the final seal. The number of middle stacked planks depends upon the height of the water anticipated.

(11) As shown in FIG. 3 and FIG. 4, the wall mount 11 comprises a rectangular metal member 21 attached through screw holes 22 to a building. The member 21 includes projection 23 which is a substantially T-shaped member with the head of the T 26 engaging an opening 25 in gasket member 27. The member 27 comprises an extending base portion 28, an inwardly extending end position 29 and an intermediate inwardly extending portion 31. The end portion 29 and the intermediate portion 31 include respective end portions 32, 33 which extend towards one another but have a space 25 to accommodate and lock the substantially T-shaped member 26 in place.

(12) The base portion 28 engages to a cross plank 10, 20 or 30 by a compression to gasket screw 40 which forces the cross plank 10, for example, against the gasket 18 forming a seal. The oblong protrusion 26 from the wall mount 11 accepts a slightly oversize accessory gasket 27 that can slide over the mount protrusion 25 and reinforce the wall gaskets 21 for a tight seal.

(13) As shown in FIG. 5, an anchor arrangement can be used to provide lateral support for long spans. A shaped metal bar or rectangular member 45 is secured to a concrete floor 46 with an anchor 47 at one end and extends upwardly and at an angle to the stacked planks 10, 20 and 30. The upper portion of the bar extends horizontally over the top plank 30 and is secured thereto by a compression screw 48. The bar 45 then extends vertically downward to a second anchor 49. Means may be provided to permit pivoting at the anchor 47 to permit various angles and the bar or rectangular member may be made in sections.

(14) FIG. 6 depicts a bracket 50 which includes a base portion 51 and a V-shaped portion 52 extending downwardly at a right angle at one end of the bracket 50. The gasket 27 is portioned within the V-shaped portion 32 and compression screw 33 secures the bracket 50 to the top plank 30 while set screw 54 secures bracket 50 to gasket 27, This prevents the planks from moving upward under the pressure of flood waters.

(15) For residential applications the invention could be made available without long production times and sold in kits. Because applicant's system is totally extruded, no initial customization is needed. Mounts 11 also can be either removable or permanent with protective covers. This invention without complex profile gaskets is faster to install and less expensive, yet achieves a superior water tight seal.

(16) While the invention has been explained by a detailed description of certain specific embodiments, it is understood that various modifications and substitutions can be made in any of them within the scope of the appended claims which are intended also to include equivalents of such embodiments.
