Method of making corrugated metal deck assembly with integrated support channels

Abstract

A method of making a corrugated metal deck assembly including an elongated corrugated metal deck portion having substantially longitudinally extending, generally U-shaped peaks and valleys. One or more support channels are formed integrally with the corrugated metal deck portion prior to casting concrete thereon. Each of the support channels are configured with a generally U-shaped cross-section having generally opposed side walls having leg portions extending generally laterally inwardly from the corresponding side walls and defining a slot facing generally downwardly from the corrugated metal deck. The support channels are adapted for receiving therethrough and supportably engaging at least portions of anchors or support items. The slots may be provided with one or more internal threads into which externally threaded portions of anchors or support items may be screwed to fixedly attach the anchors or support items to the one or more integrated support channels.

What is claimed is: 
     
         1 . A method of making a metal deck assembly for use in combination with a curable construction material and adapted for holding suspended construction equipment, the method comprising:
 providing an elongated, corrugated metal deck portion having a length defining peaks and valleys;   providing one or more support channels; and   cold forming said one or more support channels integrally with said corrugated metal deck portion prior to casting curable construction material thereon.   
     
     
         2 . The method of making a metal deck assembly for use in combination with a curable construction material and adapted for holding suspended construction equipment, as set forth in  claim 1 , wherein each of said support channels extending generally parallel to said peaks and said valleys along the length of said corrugated metal deck portion and being configured with a cross-section having generally opposed side walls and leg portions extending generally laterally inwardly from said side walls and defining one or more slots facing generally downwardly from said corrugated metal deck portion, each of said slots being adapted for receiving therethrough and supportably engaging at least portions of anchors or support items before or after setting concrete on the metal deck assembly. 
     
     
         3 . A method of making a metal deck and curable construction material assembly adapted for holding suspended construction equipment, the method comprising:
 providing an elongated, corrugated metal deck portion having a length defining peaks and valleys;   providing one or more support channels;   cold forming said one or more support channels integrally with said corrugated metal deck portion; and   casting curable construction material thereon.   
     
     
         4 . A method of making a metal deck and curable construction material assembly adapted for holding suspended construction equipment, the method comprising:
 providing an elongated, corrugated metal deck portion having a length defining peaks and valleys;   providing one or more support channels;   cold forming said one or more support channels integrally with said corrugated metal deck portion prior to casting curable construction material thereon, each of said support channels extending generally parallel to said peaks and said valleys along the length of said corrugated metal deck portion and being configured with a cross-section having generally opposed side walls and leg portions extending generally laterally inwardly from said side walls and defining one or more slots facing generally downwardly from said corrugated metal deck portion, each of said slots being adapted for receiving therethrough and supportably engaging at least portions of anchors or support items before or after setting concrete on the metal deck assembly; and   casting curable construction material thereon.   
     
     
         5 . The method of making and using a metal deck and curable construction material assembly adapted for holding suspended construction equipment, as set forth in  claim 4 , the method further comprising:
 positioning at least portions of anchors or support items in said slots for supportable engagement by said leg portions.
