Enhanced adherence uncoupling membrane (10), composed of an embossed plastic sheet (101) with recesses facing upwards, bonded on the underside to a base layer (102, 111) made of unwoven fabric, and having integral anchor points (103) exclusively inside the recesses at the bottom, to impart enhanced adhesion compatibility to the plastic sheet. When installing a floor, membrane (10) is interposed between a screed with adhesive mortar and an upper finishing layer, fixed with cementitious adhesive spread on the sheet in order to penetrate the recesses and adhere to the anchor points (103), as a discontinuous bridge that promotes adhesion. The membrane (10) improves adhesion of the adhesive in the recesses, with high picking resistance, and also makes it possible to accommodate expansion and contraction movements in correspondence with the flat portions between bosses, protecting the floor surface or other covering. The system can be manufactured easily and economically using the proposed production procedure.

The present invention relates to a fixed shade sail (1) comprising: - a tarpaulin (10) on which a lower face (10') and an upper face (10") are identified; - a plurality of anchoring bodies (11, 12, 13, 14) connected to the tarpaulin along the peripheral edge of the tarpaulin itself;- a plurality of main tie-rods (21, 22, 23, 24) which are connectable to said anchoring bodies (11, 12, 13, 14) for tensioning, in use, said tarpaulin between a plurality of supports (50) either directly or indirectly anchored to the ground. The sail (1) comprises at least one secondary tie-rod (30) of flexible type which is arranged at the lower face (10') of the tarpaulin and can be either directly or indirectly anchored to the tarpaulin itself close to or at its two ends (30', 30"). The length (L) of said secondary tie-rod (30) between the points of direct or indirect connection with the tarpaulin (10) is adjustable through tensioning means (40) so that said secondary tie-rod can be taut between two different portions of the tarpaulin until it adheres to the lower face (10') of the tarpaulin (10), which portions are chosen so that the tie-rod passes at least close to the central area of the tarpaulin and acts as a support element for the tarpaulin itself.

The anti-seismic reinforcement method for a construction element of a building includes providing a reinforcement material comprising polyurea and a priming material; applying the priming material on each of the facades (2, 3) of the construction element to obtain, on each of the facades (2, 3), a respective priming layer (5); applying the reinforcement material on the priming layer (5) by hot-spray spreading to obtain a respective reinforcement layer (4).

The invention relates to a railing assembly (1) comprising a support device (3) comprising a slab seat (20), and a mainly planar slab (2) defining an inner seat (201) and an outer seat (202) in the slab seat (20).The railing assembly (1) comprises an adjustment group (4) in the inner seat (201) controllable by a user to perform an adjustment action of the position of the slab (2).The railing assembly (1) comprises a flap (6) elastically deformable by engaging the slab (2) in the outer seat (202), and a safety body (70) movable by the user to a resting position, in which it allows elastic deformation of the flap (6), and to a working position, in which it limits or prevents elastic deformation of the flap (6).
