Ultra thin-type form panel, a form employing the same, and a method for constructing a foundation

An ultra thin form panel in which a plurality of reinforcing projecting lines extending in longitudinal directions obtained by bending a metallic plate are formed in an aligned manner with intervals being formed in lateral directions, wherein at least a part of top surfaces of respective reinforcing projecting lines are remained as coupling portions at intermediate portions in longitudinal directions while the remaining portions are cut in lateral directions to form guiding portions for bending, wherein engaging holes are formed on one side portion of the form panel in the lateral direction while engaging projecting portions are formed on the other side portion in the lateral direction such that adjoining form panels are made to be connectable.

A form comprising:

• an ultra thin form panel in which a plurality of reinforcing projecting lines extending in longitudinal directions obtained by bending a metallic plate are formed in an aligned manner with intervals being formed in lateral directions, wherein guiding portions for bending are formed at intermediate portions in the longitudinal directions by cutting at least top surfaces and both lateral sides of the respecting reinforcing projecting lines in lateral directions and the remaining portions remain as coupling portions, and
• a first and second reinforcing rail outwardly fitted and fixed to both lateral edges of the form panel in longitudinal directions along the lateral direction of the form panel for retaining the form panel in a plate like shape.
