Document Type and Number:

WIPO Patent Application WO/2016/056770

Kind Code:

A1

Abstract:

The present invention relates to a roof tile capable of preventing a backflow and, more particularly, to a roof tile capable of preventing a backflow characterized in that an upper flange, which has a drain groove, and a drain channel, along which rainwater is drained, are formed on the outer surface of the body of the tile; a lower flange is formed on the inner surface of the body, the lower flange having guide protrusions for discharging frost, an inner surface for preventing a backflow of rain drops (S), and an auxiliary protrusion portion; a drain groove and a drain channel are formed on the upper flange on the outer surface of the body, the drain groove penetrating the upper flange in the up/down direction, and the drain channel being arranged on the lower portion of the upper flange and being shaped to be open downwards such that rainwater is drained; guide protrusions and an auxiliary protrusion are formed on the inner surface of the body, the guide protrusions being arranged on the lower portion of an attachment surface, in order to discharge frost, in the shape of bands protruding from the left and right sides of the inner surface so as to face each other, the guide protrusions on the left and right sides being inclined in a V-shape, and the auxiliary protrusion being arranged between a drain surface and the lower flange in the shape of a band; the lower flange is formed to be inclined such that, as the same comes closer to the upper side, the inner surface thereof rises; the drain channel is configured such that the upper portion thereof is wide, while the lower portion thereof is narrow; and a maximum drain distance is secured, ranging from the upper flange of the body to the lower flange thereof, and surface areas as large as possible are configured on both sides such that any backflow of rainwater is suppressed, thereby preventing leakage of water, and corrosion of the framework is prevented.
