ABSTRACT:
Paving support apparatus is provided which includes substantially vertical strip restraining elements for defining a boundary around paving members and the like which move laterally during use. The support apparatus is disposed below local ground level during use. The vertical strip restraining elements include an inner surface facing toward the paving member for receiving substantially horizontal forces. Horizontal extension elements are provided which extend out from an outer surface of the vertical strip restraining elements in at least the lower region of the upright strip restraining elements for receiving vertical forces relative to the ground surface. Force converting or reinforcing elements are provided for converting the horizontal forces received by the vertical strip restraining elements into vertical forces against the horizontal extension elements, thereby restraining the paving members in the boundary. The horizontal extension elements extend inwardly of the boundary to underlie the paving members and accept vertical forces to thereby clamp the support apparatus and resist horizontal movement thereof. Preferred embodiments include unitary molded plastic support members exhibiting substantially planar upright member portions engageable with paving members, a substantially lower base member portion extending from both sides of the upright member portion by a substantial distance and a reinforced member portion connecting the upright member portion and the base member portion.
