Abstract

Disclosed is a method for installing a no-drilling foundation stone for installing a photovoltaic structure on a building. According to an embodiment of the present invention, the foundation stone is a cylindrical concrete structure having the shape of "凸" and comprising an anchor, in a center part thereof, for coupling with a photovoltaic structure, and the anchor is fixed to and protrudes upward from the foundation stone, and the method for installing the no-drilling foundation stone may comprise: a step of removing an area of a waterproof layer and a mortar layer of a rooftop of a building such that the foundation stone is inserted therein; a step of applying an adhesive substance over a reinforced concrete layer of the rooftop of the building exposed due to the removal; a step of coupling the foundation stone to the reinforced concrete layer over which the adhesive substance has been applied; a step of filling the space between the coupled foundation stone and the gradient mortar layer of the rooftop by using a backer rod; and a step of applying a waterproof paint over the foundation stone and the filled backer rod.

Abstract

Disclosed is a base stone for supporting a photovoltaic structure by way of a non-drilling method. The base stone for supporting a photovoltaic structure according to an embodiment of the present invention comprises: a lower end concrete part coming in contact with and fixed to the ground; an upper end concrete part on the lower end concrete part; and a plate anchor, penetrating the central axes of the upper end concrete part and the lower end concrete part and protruding from the upper end concrete part, for being coupled to a photovoltaic structure, wherein the upper end concrete part and the lower end concrete part have a cylindrical shape, the diameter of the lower end concrete part is larger than that of the upper end concrete part, and the upper end concrete part and the lower end concrete part are coupled to each other such that the central axes thereof are aligned, and may be formed in the shape of "凸".
