A fret-shaped sheath for laying floors and/or linings and their following quick pulling away in case of replacement, including a fixed sheath (1) and a removable sheath (2) able to fit each other by their frets, wherein removable sheath is provided with elements suitably disposed along the joint surfaces between the sheaths and able to form rooms close to the joint surfaces which are prevented from being filled with glue or mortar of cement in order to retain the capability of being deformed of the joint surfaces between the fixed sheath and the removable sheath.

The invention claimed is: 1. A fret-shaped sheath for laying at least one of floors and linings and being configured for quick pulling away in case of replacement, said fret-shaped sheath including: a fixed sheath; and a removable sheath, said fixed sheath and said removable sheath being configured
The invention claimed is: 1. A fret-shaped sheath for laying at least one of floors and linings and being configured for quick pulling away in case of replacement, said fret-shaped sheath including: a fixed sheath; and a removable sheath, said fixed sheath and said removable sheath being configured to fit each other by their frets, wherein said removable sheath is provided with means suitably disposed along joint surfaces between said fixed sheath and said removable sheath and that form compartments close to said joint surfaces between said fixed sheath and said removable sheath which are prevented from being filled with glue or mortar of cement, said compartments each including a space between one of the walls forming said compartment. 2. The sheath according to claim 1, wherein said fixed sheath is provided with recesses and projections which are able to fit the corresponding projections and recesses of said removable sheath, respectively, said recesses and projections being shaped essentially like a dove tail. 3. The sheath according to claim 2, wherein the joint surfaces between said fixed sheath and said removable sheath are made of an elastic material. 4. The sheath according to claim 1, wherein only said removable sheath is capable of being deformed during removal or dismantling, said fixed sheath being prevented from deforming once a concrete bed of a supporting wall for said fret-shaped sheath is set. 5. The sheath according to claim 1, wherein only corners of fret projections of said removable sheath are capable of being deformed to get free of said fixed sheath, said deformation being possible owing to said compartments being free of glue or mortar of cement. 6. The sheath according to claim 1, wherein said means preventing said compartments from being filled consists of a sloped wall located near each inside corner of said removable sheath. 7. The sheath according to claim 6, wherein said sloped wall is parallel to the fret and is fastened to said removable sheath only by one longer side of said sloped wall, an other side of said sloped wall being freely movable and ending at a short distance from an inside surface of said removable sheath to prevent the mortar of cement from filling accidentally said compartment covered by said sloped wall that must remain empty to allow bending and deformation of generally vertical walls of the fret with respect to a horizontal wall. 8. The sheath according to claim 7, further comprising a projecting rib acting as a protective shield against the glue or cement is arranged at the free side of the sloped wall on a surface of the removable sheath in order to prevent the glue from entering accidentally the area between said sloped wall and an underlying one of said compartments that must remain empty. 9. The sheath according to claim 6, wherein the sloped wall is fastened longitudinally to said removable sheath at both sides and two walls of said removable sheath ending at the corner thereof are separated from each other so that said sloped wall connects structurally a horizontal wall of said removable sheath and an adjacent, essentially vertical wall of said removable sheath. 10. The sheath according to claim 6, wherein said sloped wall is a hollow bead which is opened longitudinally at the corner of said removable sheath facing said fixed sheath so that each said bead connects a horizontal wall of the removable sheath to an adjacent, essentially vertical wall of said removable sheath, thus preventing the compartment at said corner from being filled by the glue. 11. The sheath according to claim 1, wherein, for applications in which at least one of an underground bed and walls suffer from particular humidity problems, there are provided transpiration channels for outlet of vapour which are disposed just beneath said fixed sheath along the fret thereof. 12. The sheath according to claim 11, wherein said transpiration channels are formed by a bead of said fixed sheath having a cross section shaped like an umbrella which runs longitudinally inside the fret of said fixed sheath and rests with its “wings” or laps on two respective ribs slightly in relief with respect to a surface of the fret so as to form longitudinal channels which are not filled by the glue from a concrete bed or a wall for said fret-shaped sheath. 13. The sheath according to claim 12, wherein even when humidity cannot enter directly said fixed sheath and said removable sheath, said transpiration channels being configured so that the humidity travels along the fret of said channels until peripheral surfaces of at least one of a floor and a wall formed by said fret-shaped sheath and is dispersed to the environment. 14. The sheath according to claim 12, wherein a cross section shape of said bead has corrugated “wings” or generally triangular wings. 15. The sheath according to claim 1, wherein outer sides of said fixed sheath and said removable sheath are provided with ribs parallel to the fret and also shaped like a dove tail in order to improve seaming and sticking of said fixed sheath to a concrete bed or a wall as well as tiles or plaster to said removable sheath. 16. The sheath according to claim 1, configured for inside and outside plasters, wherein said fixed sheath and said removable sheath provide thermal insulation due to a “thermal shear” given by the two sheaths that are different and separated even if they penetrate each other, and wherein said fixed sheath and said removable sheath are of plastic material so as to provide insulation from humidity and at least one of said fixed sheath and said removable sheath is not provided with through-holes. 17. The sheath according to claim 15, configured for anchoring finishing plasters to walls causes a clear break to propagation of cracks and settling between the wall and the plaster just because of the presence of two sheaths that are different and separated even if they penetrate each other, so that said fret-shaped sheath provides a mechanical anchorage due to the outside dove-tail scoring or ribbings and the shape of the fret as well. 18. The sheath according to claim 17, wherein anchorage of said fixed sheath and said removable sheath to the walls also by means of dowels in addition to cement glue prevents partition walls from sudden collapse suddenly in case of earthquake as said fixed sheath and said removable sheath act as stiffening means that give stability to the partition walls, so that a stabilizing action prevents or slackens the sudden collapse of the walls, even when it does not increase the resistance of the walls, and gives occupants a longer time to leave a building containing the walls. 19. The sheath according to claim 2, wherein only said removable sheath is capable of being deformed during removal or dismantling, said fixed sheath being prevented from deforming once a concrete bed of a supporting wall for said fret-shaped sheath is set. 20. The sheath according to claim 13, wherein a cross section shape of said bead has corrugated “wings” or generally triangular wings. 21. A fret-shaped sheath for laying at least one of floors and linings and being configured for quick pulling away in case of replacement, said fret-shaped sheath including: a fixed sheath; and a removable sheath, said fixed sheath and said removable sheath being configured to fit each other by their frets and are connected to each other only by their shapes, wherein said removable sheath is provided with means suitably disposed along joint surfaces between said fixed sheath and said removable sheath and that form compartments close to said joint surfaces between said fixed sheath and said removable sheath which are prevented from being filled with glue or mortar of cement.
