Device for fixing a tile to a structure, for example a supporting structure or an intermediate structure of a building, and ceiling suspended from a structure

Abstract

A device for fixing a tile to a structure, for example a supporting structure or an intermediate structure of a building, the fixing device having a suspension comprised of a threaded rod and a safety hook, a first end of the threaded rod being arranged so as to be connected to the structure, the safety hook being made integral with a second end of the threaded rod by a nut system; a tube retained in the safety hook, and a fastening hook fixed by a rigid connection on a platelet, the platelet arranged so as to be fixed to one main face of the tile, the fastening hook extending in a direction substantially perpendicular to the platelet, a free end of said fastening hook being shaped so as to be placed resting on the tube. The invention also relates to an associated suspended ceiling and to making non-planar suspended ceilings.

1 . Device for fixing a tile to a structure, for example a supporting structure or an intermediate structure of a building, which fixing device is characterized in that it comprises:
 a suspension means comprised of a threaded rod and a safety hook, a first end of the threaded rod being arranged so as to be connected to the structure, the safety hook being made integral with a second end of the threaded rod by means of a nut system;   a tube retained in the safety hook; and   a fastening hook fixed by means of a rigid connection on a platelet, which platelet is arranged so as to be fixed to one main face of the tile, the fastening hook extending in a direction substantially perpendicular to the platelet, a free end of said fastening hook being shaped so as to be placed resting on the tube.   
     
     
         2 . Device for fixing a tile according to  claim 1 , wherein the fastening hook has a flat main portion extending in a plane perpendicular to the platelet, the main portion of the fastening hook extending also in a plane substantially perpendicular to a longitudinal axis of the tube when the fastening hook is placed on the tube, and wherein the free end of the fastening hook has a notch having shapes and dimensions adjusted to associated dimensions of a cross-section of the tube, in order to permit a free rotation of the hook about the tube. 
     
     
         3 . Device according to  claim 1 , wherein the platelet comprises at least one through-recess permitting to fix the platelet to the main face of the tile by means of a screw. 
     
     
         4 . Device for fixing a tile according to  claim 1 , wherein said safety hook is provided with a non-return system capable of guaranteeing the maintaining of the tube in the safety hook. 
     
     
         5 . Device for fixing a tile according to  claim 1 , comprising a stud shaped so as to connect two tubes by means of a rigid connection. 
     
     
         6 . Device for fixing a tile according to  claim 1 , including end supports permitting the placement and fixing of said tube to walls at its ends. 
     
     
         7 . Device for fixing a tile according to  claim 1 , including a hooking rail shaped so as to be made integral with the structure, the hooking rail comprising at least one through-recess shaped so as to receive the first end of the threaded rod, the device also comprising a double nut for immobilizing the first end of the threaded rod in the recess of the hooking rail. 
     
     
         8 . Device for fixing a tile according to  claim 1 , including a spacer positioned above said safety hook and directly hooked to said threaded rod by friction, so as to permit to rigidify the whole of the fixing device. 
     
     
         9 . Ceiling suspended from a structure, e.g. a supporting structure or an intermediate structure of a building, which suspended ceiling comprises a plurality of tiles suspended by means of a fixing device according to  claim 1 . 
     
     
         10 . Ceiling suspended from a structure, e.g. a supporting structure or an intermediate structure of a building, which suspended ceiling comprises:
 a plurality of suspension means, each suspension means being comprised of a threaded rod and a safety hook, a first end of the threaded rod of each suspension means being arranged so as to be connected to the structure, the safety hook of a suspension means being made integral with a second end of the threaded rod of said suspension means by means of a nut system ( 8 );   a plurality of tubes comprising at least two tubes, each tube being maintained in a substantially horizontal position in the safety hook of at least two suspension means;   a plurality of tiles comprising at least two tiles;   a plurality of fastening hooks, at least two hooks per tile, a first free end of each fastening hook being placed on a tube and a second end of each fastening hook being fixed by a rigid connection to a main face of one single tile, each fastening hook extending in a direction substantially perpendicular to the main face of a single tile, which it is fixed to; and   at least two suspension means having different lengths and/or at least two fastening hooks having different lengths, so that the two tiles extend in different planes.
