Abstract: A plastic extruded member is provided which will induce cracks in concrete and provide drainage for moisture entering the cracks. The member includes a base which sets upon the subgrade surface, with a pair of legs extending upwardly from the base. Arms extend laterally outwardly from each leg. As extruded, the legs are adjacent one another, and then spread apart as the concrete cures and shrinks, thereby inducing a substantially vertical crack in the concrete above the legs. The member includes a drain channel at the lower end of the legs. The gap between the legs which is created by the shrinking cured concrete provides a path from the crack to the drain channel for draining water entering the crack.

Abstract translation: 提供塑料挤压件，其将在混凝土中引起裂缝，并为进入裂缝的水分提供排水。 该构件包括设置在路基表面上的基部，一对腿从基部向上延伸。 臂从每条腿横向向外延伸。 当挤出时，腿彼此相邻，随着混凝土固化和收缩而分散，从而在腿上方的混凝土中引起基本垂直的裂缝。 该构件在腿的下端包括排水通道。 由收缩的固化混凝土产生的腿之间的间隙提供了从裂缝到排水通道的路径，用于排出进入裂缝的水。
