Abstract

The eaves tile consists of two assembled bodies (1,18), the body (1) being an element in polyurethane resin or in vibrating-compressed cement mixture, made impermeable using resins and being treated on the surface using water-repellent products, whereas the body (18) is a tile-shaped element.

Description

It is to be considered that in the downstream part of the roofs with tile covering eaves tiles are used, so known because they are the tiles placed near the eaves. In the art, the eaves tiles are actuated placing the tiles with concavities upwards with a distance enough to can place, in complementary way, tiles with concavity downward. This mounting method determines covering able to guarantee impermeability and contemporary permits the aeration of the underlying part of the roof. For the position keeping, the tiles with concavity upwards are fixed to the roof with cement mortar and common joists are placed to rise the first line of tiles so to not -have angles between the tiles and have planarity characteristics to the tile covering or small relieves in this first line. Unfortunately, the cement mortar, applied to the tiles in these points, permits the imbibition. Infact, the driving rain or condensation are absorbed to the cement mortar favouring infiltration under the roofing. Moreover, such as the known eaves tiles must permit the aeration to the underlying part of the roof they are opened to water infiltrations, coming to the part near the gutter, in the case of driving rain or of winds affecting onto the water layer caused to the rain flowing from the roof to the underlying gutter. The invention refers to a new eaves tile able to permit a high impermeability to the roof and contemporary to determine a good aeration of the part of the roof underlying the tiles. Moreover, the invented eaves tile is able to eliminate the use of the common joist and the cement mortar actually used. Moreover, the invented tile permits a higher mounting speed in comparison with the realizations known in the prior art. In the art are known the document WO 01/27408 and the document WO 2005/103407 . Document WO 01/27408 refers to a roofing panel with projections to obtain, with tiles put on projections, some channels to increase ventilation under the roof using conventional means of fixing of the tiles without using cement mortar and/or common joist. Document WO 2005/103407 describes particular roofing systems that use closure strips to prevent ingress of moisture and other matter under the roof, but this roofing system is not able to avoid the imbibition of the cement used to fix tiles at the roof, because cement is present out of the protection of the strips. The invented eaves tile consists of a body 1 in polyurethane or in vibrating-compressed cementer mixture, to be impermeabilized with resins and treated onto the surface with water-repellent products. The body 1 has a back vertical wall 2 with upper outline border 3 equal to the inside profile of the tiles. Onto said back wall 2 are then present holes 4 with bigger conicity toward the outside part of the wall 2, considering for the outside part the part placed in front the eaves. Perpendicularly to the back wall 2 and on the outside part two concave surfaces 5 and 6 are present in material continuity with the back wall 2. The concave surfaces 5 and 6 have rises 7 and 8 placed in the middle of the corresponding cavities and having blind holes 9, 10, 11 and 12 able to contain the teeth 13, 14, 15 and 16 placed onto the lower wall 17 of the tile-shaped body 18. Onto the lower part of the body 1 is, further present a drop-break groove 19. In composition of the two bodies 1 and18, the rise 7 with the blind holes 9 and 10 contains the teeth 13 and 14 whereas the other rise 8 with the blind holes 11 and 12 contains the teeth 15 and 16. Other teeth 20 and 21, placed under the tile-shaped body 18, come to be in the concave surfaces 5 and 6, over the rises 7 and 8 so bigger limited the translation possibility long the roof plane. In material continuity then are present, under the concave - surfaces 5 and 6, the projection parts 22 and 23 that form the support structure the eaves tile to the roof plane. The back wall 2 has, moreover, an arc vertical profile 24 with border 25 so to be brought near the corresponding vertical border 26 of an adjacent eaves tile so closing the spaces between the adjacent bodies 1 and recovering in this way the inevitably tolerances to the mounting between the bodies 1. In positioning step, the body 1 of the invented eaves tile 1-18 is blocked on the roof 1 by means of suitable glues placed onto the projection parts 22 and 23 which form the support structure to the roof. Long the same line, and in adjacent manner to the first body 1, a second body 1 is laterally placed with the arc profile 24 of the first body in contact with the border 26 of the following one. In prosecution are so fixed a number of bodies 1 as wanted to the length of the roof border. Into the bodies 1 are then placed a corresponding number of tile-shaped bodies 18, being careful to put the teeth 13, 14, 15 and 16 into the corresponding blind holes 9, 10, 11 and 12 and the teeth 20 and 21 into the concave surfaces 5 and 6. In the same manner it is possible gluing directly for all the length of the roof border the eaves tiles already assembled, i.e. with the bodies 1 and the tile-shaped bodies 18 already connected with the teeth inserted in the corresponding blind holes and into the cavities. Then it is to be considered that the back wall 2 with holes 4 is able to permit air passing connected to the convective motion and to avoid water infiltrations under the roof. In fact, it comes to form a sole wall without openings under the tiles such as the arc profile 24 in contact with the border 26 of the body 1 placed following permits the rain seal infiltrated for the wind in said positions. Moreover, the flaring of the holes 4, oriented in the way previously described, favours the ventilation of the garret thanks to the Venturi effect that is created in said area. Instead, in presence of perturbations with wind, the heat present in the garret inverts the air flow passing to the holes 4. The air circulation is so able to go out to the holes 4 avoiding to the drops or to the water sprinkles to penetrate over the back wall 2 and the conicalness of the holes 4 is so to make falling down eventual drops or water sprinkles toward the eaves. The invented eaves tile is of immediate and speed mounting for the covering of roof and it has not the necessity of joists or of fixing with cement mortars to have the planarity of the tiles in the covering of for the small rising of the tiles placed near the eaves. Further, the invented tile avoids the passage of birds or of other animals under the tile covering. The invented eaves tile is illustrated in a merely indicative way in the drawings 1, 2, 3, 4 and 5. Figure 1 is a frontal view of a body 1. Figure 2 is a top view of a body 1. Figure 3 is a bottom view of a body 1. Figure 4 is a perspective view of the invented tile in the phase of assembling of a body 1 with a body 18 so as to form the eaves tile. Figure 5 is a perspective view of the assembled eaves tile.
