Interlocking panel for light weight insulating concrete

Abstract

An interlocking panel configured for lightweight insulating concrete has channels which form a profile that includes transversely protruding anchoring cavities. When the lightweight insulating concrete is poured into the channels and hardens, the concrete interlocks and forms an underside interlocking which resists vertical separation of the concrete from the deck panel.

1 . A deck panel for receiving light weight insulating concrete (LWIC) to create a generally flat upper roofing structure, comprising:
 a panel having an upper aerial surface for receiving LWIC and extending between opposed first and second edges; and   a multitude of transversely spaced parallel channels traversing said panel and longitudinally extending between said edges, said panel defining a transverse profile defined by the geometry of said channels wherein each channel has at least one transversely protruding anchoring cavity with an upper and a lower wall.   
     
     
         2 . The deck panel of  claim 1 , wherein each channel has two opposite anchoring cavities, each with an upper wall and a lower wall. 
     
     
         3 . The deck panel of  claim 2 , wherein each channel is symmetric about a central longitudinal plane through said channel. 
     
     
         4 . The deck panel of  claim 1 , wherein a said channel has a transverse profile segment having a generally inverted T-shape. 
     
     
         5 . The deck panel of  claim 1 , wherein a said channel has a said transverse profile segment having a general L-shape. 
     
     
         6 . The deck panel of  claim 1 , wherein a said anchoring cavity has a transverse profile segment having a bulbous shape. 
     
     
         7 . A roofing assembly comprising:
 a deck panel having an upper aerial surface and longitudinally extending between first and second edges, a multitude of transversely spaced parallel channels traversing said panel and longitudinally extending between said edges, said panel having a transverse profile defined by the geometry of said channels wherein each channel has at least one transversely protruding anchoring cavity with an upper wall and a lower wall; and   lightweight insulating concrete (LWIC) overlying said aerial surface and extending into said channels and forming an integral rigid structure which interlocks with said deck panel.   
     
     
         8 . The roofing assembly of  claim 7 , wherein each channel has two opposite anchoring cavities, each with an upper wall and a lower wall, and said LWIC extends into said anchoring cavities. 
     
     
         9 . The roofing assembly of  claim 8 , wherein each channel is symmetric about a central longitudinal plane through said channel. 
     
     
         10 . The roofing assembly  claim 7 , wherein a said channel has a transverse profile segment having a generally inverted T-shape. 
     
     
         11 . The roofing assembly  claim 7 , wherein a said channel has a said transverse profile segment having a general L-shape. 
     
     
         12 . The deck panel of  claim 7 , wherein a said anchoring cavity has a transverse profile segment having a bulbous shape. 
     
     
         13 . A process for constructing a decking structure comprising:
 providing a panel having an aerial surface for receiving LWIC and longitudinally extending between first and second edges, and a multitude of transversely spaced parallel channels traversing said panel and longitudinally extending between said edges, said panel having a transverse profile defined by the geometry of said channels wherein at least one channel has at least one longitudinally extending, transversely protruding anchoring cavity with an upper and a lower wall;   pouring flowing light weight insulating concrete LWIC over the panel so that the flowing LWIC substantially fills each channel and protrusion and forms a relatively flat surface along the aerial surface of the panel; and   allowing the LWIC to harden in a said anchoring cavity to form an integral structure which interlocks with said panel.
