Abstract: A linear drain group of fluids from an environment having a collection channel of fluids to be drained includes a cover body, superimposed on the collection channel, and a plurality of support feet coupled to the cover body and arranged resting on the collection channel to support the weight of the cover body. A discharge unit has a drain hole located on the bottom of the collection channel and shaped to allow drainage of the flow of fluids. The collection channel has a plurality of shaped reliefs emerging from the bottom so as to provide the support feet with a base in elevation with respect to the bottom. The shaped reliefs are arranged in succession on at least two parallel orders and a plurality of areas of the bottom are interposed between each order to limit the overall dimensions of the reliefs.

Abstract: A support for raised floors includes a base and a head coupled to the base, the head having a support body and a tilting element laid on the support body, the tilting element having a plate-shaped portion with an upper surface that is partially flat for supporting a building elements, protrusions emerging from a circular crown of the lower surface of the plate-shaped portion to create a profile shaped as a spherical cap ring, the outer edge of the circular crown being near the outer perimeter of the plate-shaped portion, the support body having an upper surface defining a cavity that is counter-shaped to the spherical cap ring at the protrusions emerging from the tilting element.

Abstract: A head for supports of raised floors includes a support body having an upper surface shaped as a cavity partially counter-shaped to receive a spherical cap; a protrusion emerging from the upper surface of the support body and having a threaded side wall; a tilting element having in its upper part a flat surface for supporting building elements and in its lower part a portion partially shaped like a spherical cap configured to be laid on the support body, the tilting element having a through hole configured to receive the protrusion; and a ring nut having an inner surface and an outer lateral surface, the inner surface being threaded to mesh with the threaded portion of the side walls of the protrusion, the outer lateral surface being shaped to abut against the inner surface of the through hole in the tilting element.
