Abstract: A building panel assembly has a first end support, a second end support, and an intermediate support positioned in spaced parallel relationship to each other, a deck positioned on the supports and having a plurality of low flutes extending across the deck in transverse relationship to the end supports, a plurality of fasteners affixed in the low flutes for securing the deck to the first end supports and a plurality of fasteners affixed in the low flutes of the deck so as to secure the deck to intermediate support. The fasteners used to attach the deck to the intermediate support are of a fewer number than the fasteners used to attach the deck to the end supports.

Abstract: A crimping tool including a frame, a die fixedly and non-pivotally supported by the frame, a punch arm pivotally mounted on the frame, a mating die affixed to the punch arm, and an actuator interconnected to the punch arm for moving the mating die between a first position in which the mating die engages the die and a second position in which the mating die is spaced from the die. The mating die is a male die having a generally triangular cross section.
