Definitions
- the invention relates to a device for fixing a slab to a structure, for example a supporting structure or an intermediate structure of a building, and a ceiling suspended from such a structure. More specifically, the present invention relates to a complete device for setting up and maintaining a suspended ceiling, which ensures inclined positioning of the ceiling slabs and / or positioning on different levels relative to the horizontal, thus achieving a suspended ceiling that is not flat but volumic and has an acoustic correction. This device allows a multitude of different ceilings in shape and relief.
- a suspended ceiling has no structural function in a building. It has the following functions:
- a suspended ceiling is, according to the usual definition in the field of building construction, a suspended ceiling by means of a suspension system or a skeleton or edge profile directly attached to a structure of a building (load-bearing structure such as roof, beam or walls, or intermediate fixing structure or even ceiling attached to the supporting structure).
- a false ceiling is generally composed of a plurality of flat slabs, of small thickness (of the order of 1 to 3 centimeters) with respect to the dimensions of their main faces (length, width of the order of a few tens of centimeters to a few meters), slabs positioned in the same plane on a grid support structure attached to the load-bearing structure of the building.
- document FR 1 424 561 describes such a slab fixing system.
- the system includes a plurality of inverted T-section rails.
- One foot of the T rails is intended to be attached to the structure carrier.
- the two branches of the T are intended to support the edges of the slabs, which are then immobilized on the rail by leaf springs.
- the two branches of the T being flat and parallel, the false ceiling obtained is perfectly flat.
- the invention proposes a new device for fixing a slab to a structure, a new device that makes it easy to fix slabs at varying heights and inclinations.
- the invention provides a device for fixing a slab to a structure, comprising:
- a hanger consisting of a threaded rod and a safety hook, a first end of the threaded rod being arranged to be connected to the structure, the safety hook being secured to a second end of the threaded rod by a system nut,
- Structure means here a structure of a building such as a supporting structure (roof, frame, beam, walls, etc.), an intermediate structure attached to the supporting structure and intended to carry the false ceiling (in the case of a very tall building in particular), or even a real pre-existing ceiling in a building.
- the main face of the slab is naturally one of the large faces of the slab, suspended ceiling slabs are generally flat, parallelepiped shape with a small thickness.
- each fixing hook is intended to be fixed on a single slab so that it is possible, in particular by choosing fastening hooks of different lengths and / or by adjusting the height of each safety hook, to fix the false ceiling slabs completely independently of each other.
- the presently-described device allows with inclined slabs and / or arranged on different levels to trap the sound in these openings to improve the acoustic absorption of the room and / or to return the room. sound in a privileged direction to make acoustic correction.
- the slabs of a suspended ceiling must be removable to allow maintenance of the technical elements located at the rear of the slabs.
- the attachment device presented also meets this constraint.
- the invention therefore provides a simple and standardized fixing device of the slabs of a false ceiling independently of one another, with in particular the following advantages:
- the fixing hook has a main flat part extending in a plane perpendicular to the plate; the main part of the fixing hook also extends in a plane substantially perpendicular to a longitudinal axis of the tube when the fixing hook is placed on the tube; and the end of the fixing hook has a notch of shapes and dimensions adjusted to associated dimensions of a section of the tube to allow free rotation of the hook around the tube.
- the plate comprises at least one opening opening for fixing the plate on the main face of the slab by a screw.
- the plate by definition flat, can be easily fixed on the main flat face of the slab.
- the main face of the slab may be slightly hollowed out locally, with a thickness at least equal to the thickness of the plate, so that the plate does not protrude from the main face of the slab after fixing.
- the device according to the invention may also comprise a hooked rail shaped to be secured to the structure, the hooked rail comprising at least one opening opening shaped to receive the first end of the threaded rod, the device also comprising a double nut to immobilize the first end of the threaded rod in the recess of the hooked rail.
- the hooked rail facilitates the installation of the lines.
- the device according to the invention may also comprise a spacer positioned above said safety hook and hooked directly to said threaded rod by friction, so as to make it possible to stiffen the entire fastening device and to impose a desired distance between the lines .
- the invention also relates to a ceiling suspended from a structure, for example a supporting structure or an intermediate structure of a building, suspended ceiling comprising a plurality of slabs suspended by one or more fastening device (s) as described above. .
- the advantages of the invention are essentially the ease and speed of installation (and disassembly) of such a false ceiling, to the extent that each slab is fixed independently of one another.
- Another advantage is the possibility of very quickly and easily transforming a flat ceiling into a three-dimensional ceiling, simply by replacing one or more fixing hooks, or conversely to transform a three-dimensional ceiling into a flat ceiling, for example to punctually modify the acoustics of a building.
- the invention also relates to a ceiling suspended from a structure by means of fixing devices as described above.
- the suspended ceiling includes:
- a plurality of lines each line consisting of a threaded rod and a safety hook, a first end of the threaded rod of each line being arranged to be connected to the structure, the safety hook of a line being secured to a second end of the threaded rod of said hanger by a system of nuts,
- 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 lines,
- a plurality of slabs comprising at least two slabs
- a plurality of fastening hooks at least two hooks per slab, 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 on a main face of a single slab, each attachment hook extending in a direction substantially perpendicular to the main face of the slab to which it is attached,
- FIGS. 1 and 3b show various suspended ceilings according to the invention, during the laying phase
- FIGS. 2a, 2b, 3a, 8 to 10 detail elements of the fastening device according to the invention
- FIGS. 4 to 7 show various suspended ceilings according to the invention.
- a slab fixing device essentially comprises:
- a hanger consisting of a threaded rod (6) and a safety hook (7), a first end of the threaded rod being arranged to be connected to the structure, the safety hook being secured to a second end of the threaded rod (7) by a system of nuts (8),
- the slab fixing device is composed of a set of 5 families of parts that bond to each other and thus meet the mounting constraints of a suspended ceiling with the characteristics described above. top ( Figure 1).
- the fixing device is described below starting from the slab towards the ceiling.
- This inclination can be achieved by positioning identical fastening hooks (2) on tubes (3) arranged on safety hooks (7) of different lengths, thus making it possible to generate different heights on each side of the slab (FIG. 4). , and / or by positioning tubes (2) of different dimensions on the same height of the tubes (FIG. 5).
- the tube (3) is an indispensable part of the device and plays a major role in obtaining the inclinations of the slabs and their ease of installation.
- the rounded shape of the tube in connection with the rounded shape of the free end of the fixing hook (2) contributes to the ease of laying these slabs because it allows to suspend first one side of the slab by two hooks then reassemble the entire slab by turning around the axis of the already stressed tube before coming to put the last two hooks on the tube vis-à-vis ( Figure 3b).
- Suspended ceilings with slabs arranged at different heights are made either by positioning tubes at different heights using threaded rods (6) of different heights, or by using hooks of different heights for each slab ( Figure 6). ).
- the device also allows to combine these two principles of hooked.
- a connecting pin (4) can be added to the device and allow to link two tubes together by a rigid connection.
- End supports (5) make it possible to place and fix these tubes on the walls at their ends.
- the stud (4) is not needed if a single tube is used to achieve the desired tube length.
- the end supports are not essential in the absence of walls, or if the rigidity of the assembly is sufficient.
- the hanger consists of a threaded rod (6), a safety hook (7) and nuts (8) to suspend the tubes (3).
- the safety hooks each fixed to the ceiling with a threaded rod, receive the tubes.
- the connection between the hook and the threaded rod is made by a thread pitch, which allows precise adjustments thanks to the nuts during the laying of the slabs (alignment, flatness ).
- the tube may slightly slide transversely on the hooks to allow adjustments.
- the non-return spring provided on the hook (7) prevents the tube (3) once installed in the safety hook to come out during the various manipulations of the slabs, in particular during disassembly of these slabs ( Figure 8).
- the threaded rod (6) is itself suspended from the ceiling either on the hook rail (9) by a system of double nuts, or directly in the ceiling structure (concrete, wood, primary frame ).
- the double nut makes it possible to make coarse level adjustments between the ceiling and the slabs (and to compensate for the irregularities of the ceiling), the nuts (8) on the safety hook making it possible to finalize precisely these adjustments (figure 9a).
- the hooked rails (9) facilitate the installation of the lines. Indeed, to quickly fix all the lines following the mounting of each ceiling, the hooked rail provides visual cues to the ceiling. They also serve as a guide to achieve the perforations that maintain them. They facilitate the visualization of areas of difficulty (lack of flatness, material ...) by allowing to fix the threaded rod (6) of the hanger directly to the structure of the building. They ensure the most accurate respect of the necessary distances between the lines ( Figure 9b). Hooked rails are not essential; the lines can also be attached directly to the structure.
- the spacers (11) are positioned above the safety hooks. They comprise a series of notches, distributed along the spacers, in which the threaded rods of the lines can be inserted by force.
- the Spacers thus cling directly to the threaded rods by friction (Figure 10). They make it possible to stiffen the entire fastening device by creating a grid that definitely imposes the distances between threaded rods (6), especially when they are long (length of 2 meters at the most, the limit generally imposed by the safety standards in the building). They are fixed at their ends to the walls and can also be used as a support for light equipment (insulation ). Spacers are however not essential, especially in the case where the assembly of the lines and tubes is sufficiently rigid for the intended application.
- Figure 1 shows a general view of the device of the invention with all the parts in place.
- the hooked rails (9) are fixed to the ceiling of the building, the threaded rods (6) are held by a double nut (10) to these rails.
- the safety hooks (7) fixed by two nuts (8) to the threaded rod (6) position the tubes (3) according to the ceiling mounting plan.
- the slabs (12) cling to these tubes using hooks (2) themselves fixed to the slab using plates (1).
- FIGS. 2a and 2b show an example of a plate (1) held by a screw (13) on a slab, and an example of a hook (2) which together enable the slab (12) to be connected to the tube (3). ), and which allow in particular the inclination of the slab and / or the positioning in a different plane of the plane of an adjacent slab.
- the plate 1 is a plate, for example cut from a sheet of thin thickness (1 to 3 millimeters for example), fixed flat in the main face of the slabs by one or more screws (13).
- a recess of at least the same thickness is provided in the main face of the slabs, so that the plate does not exceed the main face of the slab. This facilitates in particular the stacking and storage of the slabs against each other before use.
- the hook 2 is also cut in a thin plate (1 to 3 millimeters for example).
- the hook comprises a free end whose inner cutout (21) is adapted to the diameter of the tubes (3) to allow rotation around the tubes but without excessive play. By its shape, the free end of the hook contributes to generating the pivot connection with the tube (3) and to facilitate the installation, as well as disassembly if necessary.
- the hook also comprises a second end called locking, terminated by a foot bent at right angles to the axis of the hook and having two fins (22, 23).
- the plate comprises two hollow fins 24, 25, of the same diameter as the fins of the foot of the hook.
- the hook is secured to the plate in the following manner: the foot of the hook is inserted into the hollow fins of the plate, then the fins of the foot of the hook are moved by a rotation of the hook towards the inside of the hollow fins 24, 25 the plate where the fins 22, 23 of the foot of the hook are mechanically immobilized in the hollow fins 24, 25 of the plate.
- the hook can be unlocked and removed simply by reverse rotation. This embodiment of the plate and the hook is advantageous because:
- the plates can be fixed on the slabs well upstream, for example at the factory during the manufacture of slabs,
- FIG. 3a shows the arrangement of the device at the level of the hook (2), the tube (3) and the safety hook (7): the shape of the hook (2) allows a pivot connection on the tube (3); which facilitates the assembly (and disassembly of slabs) because it is done in two stages as shown in Figure 3b.
- Figure 4 and Figure 5 present two possible mounting models of suspended ceiling with inclined slabs.
- Figure 6 and Figure 7 show two other models of possible suspended ceiling mountings with slabs, this time arranged at different levels.
- Figures 4 to 7 highlight the multitude of ceiling mountings that the device can achieve from our standardized device.
- FIG. 8 shows a suspension model with its safety hook (7), its non-return principle (7a) which ensures the maintenance of the tube in the hook including disassembly of slabs and adjusting nuts (8).
- Figure 9a shows the ceiling-hanging device with its two-level adjustment systems.
- Figure 9b is an example of a hanging rail model.
- Figure 10 shows the spacer (11) which stiffens the entire device and can support light equipment.
