Abstract

The composite wall facing construction with apparent stones is made of facing plates each comprising a stone slab fixed to a core made of an insulating material. The stone slabs are formed with at least two holes in its side edges for receiving retention studs connected to a wall. The facing plates are stacked onto each other at least first supported by the core, and a mortar joint is packed between the stone slabs for permanent support.

Claims

1. A composite wall facing construction with apparent stones made of facing plates each comprising a stone slab fixed to a core made of an insulating material, the stone slab being formed with at least two holes in its side for receiving retention studs connected to a wall, the facing plates being stacked onto each other, guided and supported in position by the cores with the stone slabs having their edges spaced from edges of adjacent stone slabs, and a mortar joint being packed between the spaced edges of the stone slabs so that compression forces due to weight of the stone slabs is transmitted by said mortar joint, the core comprising corresponding female and male fitting formations as well as complementary side rabbets.

2. A facing construction according to claim 1, wherein the core to which is fixed the stone slab of each facing plate protrudes on two sides of the stone slab for defining a thickness of a joint which has to separate the stone slab prior to setting in position of the mortar joint.

3. A facing construction according to claim 1, comprising slots provided between the stone slab and the core.

4. A facing construction according to claim 1, wherein the holes are provided in at least one vertical side edge adjacent the upper side of said stone slabs.

5. A facing construction according to claim 1, further comprising brackets on which bear some rows of facing plates, said brackets comprising studs introduced into said holes of the stone slabs.

6. A facing construction according to claim 1, wherein the holes are filled with a bonding material prior to introduction of the retention studs.

7. A facing construction according to claim 1, wherein the retention studs are carried by an adjustable device which is fixed to a wall in front of which is mounted the facing construction.

8. A facing construction according to claim 7, wherein the adjustable device includes a rough stem, said rough stem having a head carrying the retention studs, said stem being engaged inside a slit bolt provided with a tightening nut and supported by a sole formed with an oblong hole for passage of a fixation pin.

9. A facing construction according to claim 1, comprising a flexible insulation interposed between the facing plates and a wall.

10. A facing construction according to claim 1, wherein the retention studs are placed in one of holes formed in a gallow bracket rigidly connected to a sole integrally formed by molding with said gallow bracket.

11. A facing construction according to claim 10, wherein the sole is formed with an opening of greater width that an anchoring bolt extending through a bearing plate which bears on top of said sole.

12. A facing construction according to claim 10, wherein the sole has a rear face formed with recesses.

13. A facing construction according to claim 10, wherein the gallow bracket is formed with a series of holes of biconical shape for defining a contracted portion in which a retention stud is forcibly engaged.

14. A facing construction according to claim 13, wherein the gallow bracket is formed with grooves on one at least of its sides, said grooves extending between at least some of the holes disposed according to a plurality of rows.

15. A facing construction according to claim 13, wherein said holes are offset.

16. A facing construction according to claim 12, wherein the sole and gallow bracket assembly is molded in a resin.

17. A facing construction according to claim 1, wherein the female and male fitting formations as well as the complementary side rabbets are respectively formed, with a slot, and with a protrusion, support surfaces and slanting planes being formed on said fitting formation and side rabbets, with one of said support surfaces and slanting plane having a ruptured portion defined by a recess.

18. A facing construction according to claim 17, wherein a space is provided between the protrusion and a bottom of the slot when the support surfaces and slanting planes bear together.

19. A facing construction according to claim 1, wherein the male and female fitting formations are made by taking as reference an outer face of the stone slab.

20. A facing construction according to claim 18, wherein the slanting planes lead to a joint separating two slabs.

21. A facing construction according to claim 1, comprising a granulated insulation interposed between the facing plates and a wall.

22. A facing construction according to claim 16, wherein the resin is a polyamide reinforced with mineral fibers.
