Flat Roof Support.

A flat roof or deck is composed of several elements: the support, the roof slope, the vapor barrier, the insulation, the seal, the apertures and protection or roof covering.

The flat roof or terrace is held up by a support, it fills the same role as the frame (for a pitched roof, for example).
