Grid locked stiffened panels with interlocking features
Panel for aircraft landing strip.
1. A panel suitable for use in forming a temporary aircraft landing strip, the panel comprised of:
(a) a top side comprising:
(i) a multiplicity of generally rectangular extruded members having a generally flat upper surface and lower surface having reinforcing, downwardly extending ribs thereon; and
(ii) having first and second side connection means thereon, said downwardly extending ribs on said top side disposed substantially parallel to said first and second side connection means;
(b) a bottom side comprising:
(i) a multiplicity of generally rectangular extruded members having a generally flat lower surface substantially parallel with said top side, said bottom side having an upper surface having reinforcing upwardly extending ribs thereon;
(ii) each bottom side having first and second end connecting means, said upwardly extending ribs on said bottom side disposed substantially parallel to said first and second end connection means;
(iii) said ribs on said top side crossing said ribs on said bottom side at substantially 90° and having slots formed therein, said upwardly extending ribs on said bottom side locked in said slots providing reinforcing ribs extending from end to end and side to side to form said panel; and
(iv) said panel having first and second end connection means along its end edges provided by said bottom side and first and second side connecting means along its side edges provided by the top side.
2. The panel in accordance with claim 1 wherein in said top side and said bottom side, said multiplicity of extruded members are joined together by welding.
3. The panel in accordance with claim 1 wherein said top sides are fabricated from an aluminum alloy.
4. A panel suitable for use in forming a temporary aircraft landing strip, the panel comprised of:
(a) a top side comprising:
(i) a multiplicity of generally rectangular extruded members fastened together to provide said top side having a generally flat upper surface and lower surface having reinforcing, downwardly extending ribs thereon; and
(ii) having first and second side connection means thereon, said downwardly extending ribs on said top side disposed substantially parallel to said first and second side connection means;
(b) a bottom side comprising:
(i) a multiplicity of generally rectangular extruded members fastened together to provide said bottom side having a generally flat lower surface substantially parallel with said top side, said bottom side having an upper surface having reinforcing upwardly extending ribs thereon;
(ii) each bottom side having first and second end connecting means, said upwardly extending ribs on said bottom side disposed substantially parallel to said first and second end connection means;
(iii) said ribs on said top side crossing said ribs on said bottom side at substantially 90° and having slots formed therein, said upwardly extending ribs on said bottom side locked in said slots providing reinforcing ribs extending from end to end and side to side to form said panel having first and second end connection means along its end edges provided by said bottom side and first and second side connecting means along its side edges provided by the top side.
5. The panel in accordance with claim 4 wherein in said top side and said bottom side, said multiplicity of extruded members are joined together by welding.
6. The panel in accordance with claim 4 wherein said top sides are fabricated from an aluminum alloy.
7. In a temporary aircraft landing strip wherein a multiplicity of rectangular panels are locked together to form parallel rows of releasably joined panels disposed in a side-by-side relationship and in an end-to-end relationship, each panel having a first and second end connecting means along its end edges releasably joining said panels in an end-to end relationship to form a row and first and second side connecting means along its side edges, releasably connecting rows of said panels to form said strip, wherein said panel is comprised of:
(a) a top side comprising:
(i) a multiplicity of generally rectangular extruded members having a flat upper surface and lower surface having reinforcing, downwardly extending ribs thereon; and
(ii) having first and second side connection means thereon, said downwardly extending ribs on said top side disposed substantially parallel to said first and second side connection means;
(b) a bottom side comprising:
(i) a multiplicity of generally rectangular extruded members having a generally flat lower surface substantially parallel with said top side, said bottom side having an upper surface having reinforcing upwardly extending ribs thereon;
(ii) each bottom side having first and second end connecting means, said upwardly extending ribs on said bottom side disposed substantially parallel to said first and second end connection means;
(iii) said ribs on said top side crossing said ribs on said bottom side at substantially 90° and having slots formed therein, said upwardly extending ribs on said bottom side locked in said slots providing reinforcing ribs extending from end to end and side to side to form said panel; and
(iv) said panel having first and second end connection means along its end edges provided by said bottom side and first and second side connecting means along its side edges provided by the top side.
8. The panel in accordance with claim 7 wherein in said top side and said bottom side, said multiplicity of extruded members are joined together by welding.
9. The panel in accordance with claim 7 wherein said top sides are fabricated from an aluminum alloy.
