摘要

PROBLEM TO BE SOLVED: To provide a fixing structure of a water retention drainage base material for rooftop greening, for fixing the water retention drainage base material not to rooftop waterproof layer protection concrete but to a rooftop waterproof layer, and for sufficiently protecting the rooftop waterproof layer from plant roots. SOLUTION: This fixing structure comprises laying a root prevention sheet 3 on the rooftop waterproof layer 2, making a longitudinal hole 40 reaching a concrete layer 1 which pierces into both the sheet and the layer and makes the rooftop slap of a building, establishing in a standing condition and fixing a stud bolt 10 onto the longitudinal hole 40 using a chemical anchor. Furthermore, the structure comprises attaching preferably doubly cylindrical members 12 and 15 in a condition of outward engaging with the stud bolt 10, filling a sealing material 13 inside, attaching a water retention drainage base plate 30 using the stud bolt 10, and putting soil 36 on the plate for planting.
