摘要

Multirrastrel tray with double ventilation (1) for the direct support of the tiles, and also for the placement of slate, stone, ceramic or other material plates, preferably made of profiled sheet metal, with the profiled ribs located in a perpendicular direction to the line of maximum slope of the roof and, overlapping the successive trays, characterized by placing the consecutive trays overlapping one another (the upper one over the lower one) and subsequently screwing them together successively and arranging each of them at their edges lower and upper (depending on their position in the roof plane), of two resistant longitudinal ribs whose section can present different configurations (square, rectangular, trapezoidal, u-shaped, omega-shaped, etc.), which are perforated in some of its faces to allow on the one hand, a double ventilation: the ventilation of the space between the tiles and the to tray and the ventilation of the space between the tray and the insulation (to be placed under the tray and separated from it) with which we eliminate the vapor barrier; on the other hand, the elimination of the water that could have been filtered under the tiles when passing it from one tray to the next until being eliminated by the eaves, creating a double waterproofing; there are two other types of perforations in the lower rib: one in the upper side of the lower rib of each tray (according to its position in the deck plane), to allow penetration to the base of the tray of the tight screws that fix the upper tray to lower one against each other creating a rib in conjunction with the upper one of the lower tray and the base itself of the tray for greater strength; another type is formed by a series of in-line perforations in the upper part of the descending face of the lower rib of each tray (face whose lower edge is located a few millimeters from the base of the tray without reaching it to allow the passage of water between said edge and the base of the tray), for the housing of the hooks of the slate plates, ceramic or other material where appropriate.
