Main beam structure and profile for formwork grid systems

A formwork grid system constructed from a plurality of formwork components, the formwork grid system comprising:

• a main beam run of at least 23 feet, the main beam run including a maximum of four (4) props and three (3) main beams, wherein at least one of the main beams is made of an aluminum alloy and utilizes a main beam profile that includes:
• a top horizontal support of 10 centimeters or less in width;
• a lower horizontal support of greater than 10 centimeters in width having a first end and a second end;
• a first upper vertical support extending from the top horizontal support and spanning between the top horizontal support and the lower horizontal support;
• a second upper vertical support extending from the top horizontal support and spanning between the top horizontal support and the lower horizontal support;
• a first angled support connected to the first end;
• a second angled support connected to the second end, the first and second angled supports angling inward toward a center of the main beam profile;
• a first clip area provided at a junction of the first angled support and the first end;
• and
• a second clip area provided at a junction of the second angled support and the second end.

A main beam formwork construction component, having a main beam profile comprising:

• a lower horizontal support of greater than 10 centimeters in width having a first end and a second end;
• a first angled support connected to the first end;
• a second angled support connected to the second end, the first and second angled support angling inward toward a center of the main beam profile;
• a lower vertical support attached to, the lower horizontal support;
• a bottom horizontal support at a base of the lower vertical support;
• a first leg and a second leg attached to respective sides of the bottom horizontal support;
• a first heel at a respective base of the first leg and the first angled support;
• and
• a second heel at a respective base of the second leg and the second angled support,
• wherein the inner perimeter of the first heel, second heel, first leg, second leg, and bottom horizontal support form a lower cavity T-slot for the main beam profile.
