Modular vegetated roof system

摘要

Described herein is a module for covering a surface with vegetation. The module comprises a drainage board having an upper surface for supporting a growth medium. The drainage board has a plurality of moisture receptacles extending downwardly from the upper surface for collecting moisture. The module also comprises a plurality of sidewalls having a multiplicity of apertures therethrough. Each sidewall is coupled to the drainage board and extends upwardly therefrom. The sidewalls cooperate with each other so as to provide a perimeter for surrounding the growth medium. The module may also include other features. For example, the sidewalls may be pivotally coupled to the drainage board (e.g. along a living hinge), the module may include couplers for securing adjacent modules together, the sidewalls may include a reinforcing rib, the drainage board may include an opening for receiving an irrigation nozzle therein, and there may be edging for covering the sidewalls.

1. A module for covering a surface with vegetation, the module comprising:
(a) a drainage board having an upper surface for supporting a growth medium, the drainage board having a plurality of moisture receptacles extending downwardly from the upper surface for collecting moisture; and (b) a plurality of sidewalls having a multiplicity of apertures therethrough, each sidewall being hingedly coupled to the drainage board so that each sidewall is foldable to an upright position in which the sidewall extends upwardly from the upper surface of the drainage board to cooperate with adjacent sidewalls to provide a perimeter for surrounding the growth medium, wherein the multiplicity of apertures are sized and positioned to allow for the transfer of moisture between adjacent modules, wherein the plurality of sidewalls are substantially open; and (c) a permeable membrane sized to fit between the sidewalls and cover the upper surface; (d) wherein each sidewall is hingedly coupled to the drainage board along a living hinge; and (e) wherein each sidewall has a lower flange adjacent the living hinge, the permeable membrane being sized to span the upper surface such that the lower flange overlaps the a permeable membrane when at least one of the sidewalls is in the upright position such that the permeable membrane is secured between the lower flange and the upper surface of the drainage board, the permeable membrane being sized to span the upper surface.
