Abstract

<P>PROBLEM TO BE SOLVED: To provide a flat roof tile, capable of preventing, when tiles are laid, leaking of rain resulting from intrusion of rainwater blown in through a clearance between the tile trail of one tile and an apron part at the head of the other tile placed on the same over a flashing. <P>SOLUTION: In the tile 11, a transversely continuous projection part 12 is formed in a protrusive manner on the tile trail side of the tile surface except a water receiving part so as to extend from a collar 8 at a side edge to a flashing 6. The protruding part 12 is formed so as not to be covered with the ridge-side tile head when the tile 11 is laid, and so as to be adjacent to the apron 7, and the tile trail side is tapered so that rainwater is never collected in the protruding part 12. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a flat roof tile.

  FIG. 1 shows an example of such a conventional flat tile 1, and FIG. 2 shows a cross-section of the main part of the roof that is covered with the flat tile 1. Cover the tile bottom of the roof tile 1 covered by the roof and hook the joint 2 on the back of the tile bottom on the top surface of the base material 3 such as a field board from the eaves to the roof ridge at fixed intervals, A nail is struck to the roof pier 4 through 5 and fixed.

  The tile 1 is also provided with a water return 6 for preventing rainwater blown in between the tiles on the tile bottom surface, and the tile head is formed with a front sag 7 that blocks the blowing of wind and rain.

  Depending on how wind and rain are blown in, rainwater blown from between the tile bottom of the roof tile 1 and the front sag 7 of the roof tile on the roof climbs over the water return 6 and enters as shown by the arrows in FIG. Rain leaks may occur.

  An object of the present invention is to provide a flat roof tile that is less likely to cause rain leakage due to the above phenomenon.

The flat roof tile according to the first aspect of the present invention is a flat roof tile in which a water receptacle is formed on one side edge, and does not cover the roof tile on the ridge side when the roof tile is rolled, and is positioned immediately before the drooping of the roof tile. It is characterized in that lateral protrusions that are lower in height than the water return are projected continuously in the whole length from the tile surface except the water receiver to the water receiver,
The invention according to claim 2 is characterized in that, in the flat roof tile according to claim 1, the tile bottom side of the protrusion is formed in a tapered shape.

  According to the flat roof tile of the invention according to claim 1, the rainwater which is to be blown in between the roof of the roof tile covering the roof tile on the eaves side is located immediately before the front droop in any intrusion path. The direction can be changed by hitting a strip and dissipated upward to prevent the above-mentioned blowing, and rain leakage due to the blowing can be prevented.

  According to the invention which concerns on Claim 2, the rainwater which fell along the front droop of a tile head is guided by the taper-shaped part of a protrusion, and it flows down, and is not stopped by a protrusion.

  Hereinafter, a flat roof tile according to an embodiment of the present invention will be described with reference to the drawings. In the figure, the same components as those shown in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 3 shows the flat roof tile 11 according to the present invention, and FIG. 4 shows a cross section of the main part of the roof covered with the flat roof tile 11, on the tile bottom side of the tile surface excluding the water tray. A protruding ridge 12 that protrudes laterally is formed on the entire length from the side edge collar 8 to the water return 6. As shown in FIG. 4, the ridges 12 are formed so as not to cover the roof tiles on the ridge side when the roof tiles 11 are rolled up, and are positioned just before the front sag 7 and the tile bottom side is tapered. The rainwater can flow smoothly without collecting on the ridges 12.

  According to the flat roof tile 11 of this embodiment, as shown by the arrows in FIG. 4, the rainwater that is about to blow from the lower side along the roof surface hits the ridge 11 located immediately before the front droop 7 in any intrusion path. It is prevented that the direction is changed and the air is dissipated upward and blown from between the roof tile 1 and the front sag 7.

Claims (2)

  In a flat roof tile with a water receptacle on one side edge, when it is rolled up, it does not cover the roof tile on the ridge side, and it is a sideways position that is lower in height than the water return at a position located just before the drooping of the tile head. A flat roof tile characterized in that the ridges are continuously formed over the entire length from the collar surface of the tile except the water receiver to the water receiver.   The flat roof tile according to claim 1, wherein the tile bottom side of the ridge is formed in a taper shape.
