Description

  The present invention relates to a roof greening resin tray and a roof greening structure using the tray.

The heat island phenomenon and global warming caused by urbanization and the loss of greenery have become major problems these days.
Therefore, in order to solve such problems, roof greening, rooftop greening, and the like have been proposed, and buildings and the like having such a greening structure are gradually increasing in urban areas.

  In addition, various methods have already been proposed for roof greening, in which a roof greening resin tray containing a lightweight planting base is laid on the roof and turf is cultivated on the planting base in the tray. (For example, see Patent Documents 1 and 2).

  However, in the method of laying the roof greening resin tray previously proposed on the roof, there is a problem that rainwater may overflow from the fence provided at the eaves when heavy rain falls. In other words, when heavy rain falls, rainwater cannot be absorbed by the planting base, and it cannot drain from the drain holes provided at the bottom of the tray, and rainwater may overflow from the top of the tray. Therefore, the rainwater that overflows from the top of the tray does not flow evenly along the roof slope, but flows irregularly, and in some cases, it flows into one part of the fence and overflows from the fence. .

  In addition, when the sunshine continues, it is necessary to water the tray planting base so that the turf does not wither. However, in the case of the conventional tray, a method of installing sprinklers at several locations on the roof, Since it is necessary to adopt a method of providing a water supply port for each, there is a problem that the piping structure for irrigation is complicated and expensive.
