Composite floor structure and method of making the same

A composite floor structure comprising:

• a platform having an upper floor surface;
• a plurality of transverse beams coupled beneath the platform;
• at least one longitudinal beam extending across the plurality of transverse beams;
• and
• a plurality of insert beams positioned between adjacent transverse beams to provide a continuous surface for the at least one longitudinal beam, wherein each transverse beam includes a preform and a plurality of additional reinforcing layers and each insert beam includes a preform without any additional reinforcing layers.

• a plurality of transverse beams coupled beneath the platform;
• at least one longitudinal beam extending across the plurality of transverse beams;
• a plurality of insert beams positioned between adjacent transverse beams to provide a continuous surface for the at least one longitudinal beam;
• and
• an underlayment positioned beneath the plurality of transverse beams and the plurality of insert beams and above the at least one longitudinal beam.

A composite floor structure comprising:

• a platform having an upper floor surface;
• a plurality of transverse beams coupled beneath the platform;
• at least one longitudinal beam extending across the plurality of transverse beams;
• and
• an underlayment sandwiched between the plurality of transverse beams and the at least one longitudinal beam, wherein the platform is arranged parallel to the underlayment.
