Cantilever enabled joist beam

Abstract

A main beam for a formwork grid construction component system is disclosed. Typical main beams work with secondary joists (sometimes referred to as secondary beams to support a decking surface for pouring of concrete or cement. By strengthening the main beam using an altered profile while maintaining interoperable external dimensions, the span distance of each joist may be increased. By forming the main beam with the disclosed profile, joists can be made longer (e.g., have an eight foot connected span to increase grid size) and maintain appropriate strength (or increased weight tolerance). Formwork grid systems are used in construction of buildings and other structures. Interoperability with existing components is maintained by the disclosed main beam adhering to the same external functional form factor. The external form factor being the same allows main beams constructed in accordance with this disclosure to properly function with existing formwork grid construction components.

What is claimed is: 
     
         1 . A method of clipping a joist beam as a cantilever to extend the joist beam beyond a support perimeter of a grid system, the method comprising:
 overlaying the joist beam on a first main beam located at a perimeter of a formwork grid system, a first end of the joist beam extending beyond the perimeter, a midpoint of the joist beam at an overlay point of the first main beam, and a second end of the joist beam joined to a side of a second main beam located at an interior prop of the formwork grid system;   clipping the overlaid joist beam to the first main beam utilizing a clip between an ear provided by a main beam profile of the first main beam and a T-slot of the joist beam; and   clipping the second end of the joist beam utilizing a clip between an end-cap of the joist beam and a clip area of the second main beam, the clip area of the second main beam provided by a main beam profile of the second main beam.   
     
     
         2 . The method of  claim 1 , wherein the main beam profile of the first main beam is equivalent to the main beam profile of the second main beam. 
     
     
         3 . The method of  claim 1 , wherein the joist beam is at least an eight foot joist. 
     
     
         4 . The method of  claim 1 , wherein at least one of the first main beam and the second main beams are an eight foot main beam. 
     
     
         5 . The method of  claim 1 , wherein the clip is an R 12×50 clip.
