Abstract
Abstract This panel is outstanding in that each panel is made up of a plate (1) of insulating material inserted during moulding between two layers of cement (2) and (3) of different density and thickness, the transversal faces of the end of each panel being fitted in combination in order to enable their axial alignment positioning or angular positioning at 90° while being fitted with fixing components apt to provide their assembly into position, the said panels being also designed in order to cooperate and be centered with a bottom plate and/or plate acting as a cover.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
Pre-fabricated panel for the construction of burial vaults in particular, wherein each panel is made up of a plate (1) of insulating material inserted during moulding, between two layers of cement (2) and (3) of different density and thickness, the external layer (3) being very slightly crowned, the transversal faces of the end of each panel being fitted in combination in order to enable their axial alignment positioning or angular positioning at 90° whilst being fitted with means apt in order to provide their assembly into position, the said panel being also designed in order to cooperate and be centered with a bottom plate (5) and/or a plate acting as a cover (6).
Claim 2
Dependent Claim
113 words
Pre-fabricated panel for the construction of burial vaults in particular, wherein each panel is made up of a plate (1) of insulating material inserted during moulding, between two layers of cement (2) and (3) of different density and thickness, the external layer (3) being very slightly crowned, the transversal faces of the end of each panel being fitted in combination in order to enable their axial alignment positioning or angular positioning at 90° whilst being fitted with means apt in order to provide their assembly into position, the said panel being also designed in order to cooperate and be centered with a bottom plate (5) and/or a plate acting as a cover (6).
Claim 3
Dependent Claim
31 words
Panel according to claim 1, wherein the layer (2) corresponding to the internal wall, has a greater density and thickness to those of the layer (3) corresponding to the external wall.
Claim 4
Dependent Claim
15 words
Panel according to claim 1, wherein metal reinforcements are sunk into each of the layers.
Claim 5
Dependent Claim
48 words
Panel according to claim 1, wherein the fittings of the end transversal faces have, in a complementary manner, on one side, a vertical, profiled rib (7) and on the other, a groove (8), the said ribs and grooves being formed when the cement of the layers is poured.
Claim 6
Dependent Claim
22 words
Panel according to claim 4, wherein the complementary grooves and ribs (7) and (8) are arranged according to the same axial alignment.
Claim 7
Dependent Claim
41 words
Panel according to claim 4, wherein the complementary grooves and ribs (7) and (8) are angularly offset by 90°, one of the grooves or ribs being formed on one of the side face of the panel, close to the transversal edges.
Claim 8
Dependent Claim
81 words
Panel according to claim 1, wherein the assembly means are made up of one or several breaking through holes (11) perpendicularly formed from at least one of the transversal edges, the holes corresponding with access holes (12), formed in the thickness of the external layer of cement, the said holes being likely to take fixing components (13) likely to cooperate with inserts (14) sunk into the thickness of an adjacent panel, axially opposed to the edge taking the fixing component(s) (13).
Claim 9
Dependent Claim
36 words
Panel according to claim 7, wherein the access openings (12) corresponding with the holes (11) in order to provide the passage of the fixing components (13), are also formed close to top and/or bottom horizontal edges.
