Abstract
A deck drain apparatus is provided that allows builders to inexpensively configure deck drainage systems from standard AASHTO M180 highway guardrail. The apparatus includes a number of deck drain sections, butted together to form a drain channel. Each of the drain sections consists of a pan section and an inverted W-beam section. The pan section has a longitudinally elongated and flat conducting surface and two perforated sides. The two perforated sides project upwardly along opposite lateral edges of the conducting surface. The inverted W-beam section has a first perforated wall, a first upper surface, a lower surface, a second upper surface, and a second perforated wall. The perforated walls are longitudinally elongated and formed along opposite lateral edges of the inverted W-beam section. The first upper surface is formed between the first perforated wall and the lower surface. The second upper surface is formed between the lower surface and the second perforated wall. The inverted W-beam section is inserted into the pan section, creating friction bonds between the first perforated side and the first perforated wall, and between the second perforated side and the second perforated wall.
