Modular form for cast-in-place concrete decks federally sponsored research

Abstract

A forming system for cast-in-place concrete decks supported by structural beams capable of being used on decks with varying dimensions between the structural beams. The forming modules ( 28, 30 ) interlock with the supporting ledger assemblies ( 10 ) to prevent lateral movement of the form system. The deck material between outside form assemblies ( 26 ) is fabricated to the size required to fill the gap between the outside form assemblies ( 28 ), and is supported by the interior support beams ( 16 b ) or the interior support beams ( 16 b ) and the inside form assembly ( 30 ).

1 . A form for cast-in-place concrete comprising: 
 (a) a plurality of parallel beam members    (b) a rectangular forming surface superimposed on said beam members    (c) means for attaching said forming surface to said beam members at a predetermined distance    (d) said forming surface attached to said beam members so the top surface of one of said beam members is not completely covered by said forming surface    (e) a supporting beam assembly installed transversely to said beam members    (f) said supporting beam assembly containing a void of predetermined dimension    (g) means for suspending said supporting beam assembly from structural support beams    (h) said beam member contains a void to allow passage of said means for supporting said supporting beam assembly    (i) a rectangular member attached to the end of said parallel beam members and interlocking with said supporting beam assembly    (j) a rectangular filler forming surface    (k) said rectangular filler forming surface is supported by the exposed portion of the top surface of said beam members    
   
   
       2 . The form of  claim 1  with an additional support structure comprising: 
 (a) a plurality of parallel beam members    (b) means for attaching said forming surface to said beam members at a predetermined distance    (c) a rectangular member attached to the end of said parallel beam members and interlocking with said supporting beam assembly of  claim 1     (d) said rectangular filler forming surface of  claim 1  is supported by the exposed portion of the top surface of said beam member of  claim 1  and parallel beam members of additional support structure
