Abstract

Abstract Protective waterproofing membrane particularly for exterior and/or interior coatings, of walls and pavings generally, of the types made in plastic material and comprising a plurality of protrusions all of the same side, in which, limited to the overlapping area or along the vertical junction edges, protrusions (2, 2') are provided having a different configuration in respect to the remaining surface of a sheet from a pre-determined width, said protrusions constituting respectively a male and female closure provided with a seal, which development requires both on the left and right side, an ensemble of cylindrical forms joined in groups of five, where one or the other provides a series of forms (5) also cylindrical but of a smaller diameter to the preceding and interposed in rows that are vertical to said groups.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 178 words
A protective membrane suitable for use for modular coating of walls and pavings generally of a type superimposable with an analogue for mechanical junction, obtaining the continuity of the coating, made in plastic material and comprising a central area of plurality of protrusions all on a same side of each membrane, wherein the membrane has a first border joining area and an opposite second border joining area provided with a series of male and female joining protrusions to join two of said membranes on their respective borders to form a continuous layer, one of the borders being provided with a sealing material to form a seal, said first and second border joining areas comprising: at least two lines of said male and female joining protrusions, said lines of said male and female joining protrusions being divided, the first of said borders by the sealing material; the second of said borders having at least one row of protrusions abutting in a joining action against said sealing material of the joined adjacent membrane to form a seal surrounding said protrusions.
Claim 2
Dependent Claim 178 words
A protective membrane suitable for use for modular coating of walls and pavings generally of a type superimposable with an analogue for mechanical junction, obtaining the continuity of the coating, made in plastic material and comprising a central area of plurality of protrusions all on a same side of each membrane, wherein the membrane has a first border joining area and an opposite second border joining area provided with a series of male and female joining protrusions to join two of said membranes on their respective borders to form a continuous layer, one of the borders being provided with a sealing material to form a seal, said first and second border joining areas comprising: at least two lines of said male and female joining protrusions, said lines of said male and female joining protrusions being divided, the first of said borders by the sealing material; the second of said borders having at least one row of protrusions abutting in a joining action against said sealing material of the joined adjacent membrane to form a seal surrounding said protrusions.
Claim 3
Dependent Claim 41 words
A membrane of claim 1 wherein the membrane joining protrusions comprise male and female closures arranged on longitudinal sides in an ensemble of forms in groups, and a series of third forms in an intermediate position and interposed between said groups.
Claim 4
Dependent Claim 70 words
A membrane of claim 2 wherein the membrane joining protrusions comprise a series of male closures grouped in five units respectively four diametrically opposite and one in a central position, and in which a first series of males closures is disposed in a row proximate to the longitudinal end of a membrane sheet, and parallel to the first row is provided a second row of males closures defining a space.
Claim 5
Dependent Claim 13 words
A membrane of claim 3 wherein the male protrusions are cylindrical in section.
Claim 6
Dependent Claim 115 words
A membrane of claim 2 wherein on opposite ends of a same membrane sheet, or on the side of the female closure, being logically correspondent, the ends are provided with: protrusions, with cylindrical section, grouped in fives, and respectively four diametrically opposite and one in a central position, said grouped protrusions comprising a first, second and third series, the first protrusions series proximate to the vertical end of the sheet; the second protrusions series located more internally than said first series of protrusions; the third protrusions series disposed intermediately with respect to the first and second protrusions series and vertically in rows of three in the elapsing space between the first and second protrusions series.
Claim 7
Dependent Claim 52 words
A membrane of claim 5 wherein the protrusions of the third series are dimensionally smaller in diameter in respect to protrusions of the first and second series, and from the opposite side, obtain a pair of bumps contrary to the preceding which, overlap the edges of the sheets, along the sealing material.
Claim 8
Dependent Claim 38 words
A membrane of claim 2 wherein a central area that determines thickness of interspace of ventilation between a wall and the membrane is comprises a clews ensemble, having a section substantially semispherical base provided with a resting plane.
Claim 9
Dependent Claim 70 words
A membrane of claim 1 wherein the membrane joining protrusions comprise a series of male closures grouped in five units respectively four diametrically opposite and one in a central position, and in which a first series of males closures is disposed in a row proximate to the longitudinal end of a membrane sheet, and parallel to the first row is provided a second row of males closures defining a space.
Claim 10
Dependent Claim 13 words
A membrane of claim 8 wherein the male protrusions are cylindrical in section.
Claim 11
Dependent Claim 14 words
A membrane of claim 8 wherein the sealing material is a double-sided adhesive tape.
Claim 12
Dependent Claim 16 words
A membrane of claim 1 wherein the sealing material is in a form of a strip.
Claim 13
Dependent Claim 115 words
A membrane of claim 1 wherein on opposite ends of a same membrane sheet, or on the side of the female closure, being logically correspondent, the ends are provided with: protrusions, with cylindrical section, grouped in fives, and respectively four diametrically opposite and one in a central position, said grouped protrusions comprising a first, second and third series, the first protrusions series proximate to the vertical end of the sheet; the second protrusions series located more internally than said first series of protrusions; the third protrusions series disposed intermediately with respect to the first and second protrusions series and vertically in rows of three in the elapsing space between the first and second protrusions series.
Claim 14
Dependent Claim 52 words
A membrane of claim 12 wherein the protrusions of the third series are dimensionally smaller in diameter with respect to protrusions of the first and second series, and from the opposite side, obtain a pair of bumps contrary to the preceding which, overlap the edges of the sheets, along the sealing material.
Claim 15
Dependent Claim 37 words
A membrane of claim 1 wherein a central area that determines thickness of interspace of ventilation between a wall and the membrane comprises a clews ensemble, having a section substantially semispherical base provided with a resting plane.
Claim 16
Dependent Claim 26 words
A spool comprising a plurality of attached membranes of claim 1, the attached membranes each segregated by breaking lines that define a size of each membrane.
Claim 17
Dependent Claim 11 words
A plurality of membranes of claim 1 in a stacked arrangement.
