Definitions

  • the invention relates to the field of false walls, and in particular that of suspended false ceilings.
  • the invention relates more particularly to a false ceiling comprising a load-bearing structure capable of carrying a stretched canvas and at least one panel such as a light panel.
  • the suspended suspended ceilings are made in the classic way using rails and removable flat slabs carrying a stretched canvas. More specifically, rows of rails are arranged in two perpendicular directions so as to define a grid. The slabs are placed resting on the rails, between each of the rows of the rails.
  • the ceilings are already provided with a structure in the form of parallel and opposite rails equidistant for the fixing of technical elements or their passage.
  • the production of a false ceiling, and in particular the installation of the rails intended to support the panels or slabs, is then constrained by the presence of the existing rails as well as by the transverse distance separating the latter from one another. It is therefore necessary to come and fix the profiles intended to receive the canvas stretched on the existing rails beforehand in order to then fix the canvas on the latter and thus form the slab.
  • a false ceiling comprising a panel fixed to two rail bodies by means of elastic retaining profiles.
  • Each retaining section comprises means for hooking onto one of the stringer bodies as well as an elastic arm exerting a thrust on the panel such that the panel is kept pressed against a bearing zone of the stringer body.
  • the invention aims to remedy these problems by proposing a false ceiling and an installation method making it possible to solve the problems referred to above.
  • the object of the invention is to provide a false ceiling offering rapid, easy and safe installation and removal of a panel while limiting the shadow cast on the canvas when the panel is a light panel.
  • the invention provides a false ceiling according to the subject of claim 1.
  • the panels are held on the shoulders by simple gravity, while being prevented from falling due to improper handling of the latter or their displacement with respect to the profiles, and whatever or the dimensions of the shoulders on which the panels rest.
  • the wedging means can also have the advantage of ensuring a centered positioning of the panels relative to the profiles.
  • the wedging means are placed in vertical support on the bearing surfaces of the profiles.
  • Each wedging means is interposed transversely between a lateral edge of the panel and a vertical bearing face of an associated profile oriented towards the opposite profile.
  • the wedging means have a nominal transverse width established as a function of the width of the panel and the width of the access opening to the ceiling so as to prevent a transverse displacement of the panel such that one of the side edges of the panel comes. position themselves facing the passage opening, the panel having a width greater than the width of the ceiling access opening.
  • the wedging means are thus arranged to prevent transverse movement of the panel on the profiles, apart from a clearance necessary to allow rapid positioning of the panel on the profiles and their removal by simple pushing.
  • Each wedging means is a wedging bar, the elongate body of which rests vertically along a bearing surface of an associated section, and which is interposed transversely between a lateral edge of the panel and a vertical bearing face of the associated profile oriented towards the opposite profile.
  • the wedging bar comprises at least one elongated flat lower face capable of being supported along a bearing surface of an associated section.
  • the wedging bar has a rectangular or square cross section so as to include two opposite elongate flat side walls capable of being interposed transversely between a side edge of the panel and a vertical bearing face of the associated profile oriented towards the opposite profile.
  • the shoulders of the profiles define a bearing surface having a transverse width greater than or equal to 5 millimeters so as to limit the shadow cast on the canvas placed under the panel when the latter is a light panel while ensuring the maintenance of the panel via the presence of the locking means.
  • the bearing surfaces of the profiles are located at the same height.
  • the profiles, of triangular section include a notch formed in the upper part, the intersection of two faces of the notch defining the shoulder.
  • the panel comprises light means.
  • the false ceiling comprises a stretched canvas fixed in the lower part of the profiles, extending parallel to the panel.
  • the invention also relates to a method according to claim 9 for installing a panel on a ceiling provided with an existing structure for producing a false ceiling.
  • the method comprises a step d) consisting in placing at least one other removable wedging means attached to a bearing surface of the other of the profiles.
  • transverse orientation will be designated corresponding substantially to the horizontal orientation of the panel in position, and the longitudinal orientation in the horizontal direction orthogonal to the plane of the figures.
  • a false ceiling 1 comprising a supporting structure 2, at least one panel 3, advantageously luminous, a stretched fabric 5 and means for wedging the panel 3 on the supporting structure 2.
  • the supporting structure 2 comprises a series of sections 20, 21 parallel to each other, and preferably equidistant from each other, fixed to a ceiling 4. In the example illustrated, only two transversely opposed sections 20, 21 are shown.
  • the profiles 20, 21 are fixed to the ceiling 4 via rails 6 carried by the ceiling 4. As will be seen later, during the description of the installation of the light panel 3, these rails fall under an existing structure of the ceiling. .
  • the profiles 20, 21 are coplanar and extend parallel to one another. They are symmetrical with respect to one another and are arranged between them so as to define an access opening to the ceiling 4 of transverse width "D".
  • each section 20, 21, of triangular section has a horizontal upper surface 200, 210, the other two surfaces defining an internal surface 201, 211 inclined and a vertical external surface 202, 212 of the structure. carrier 2.
  • internal surface of a section 20, 21 is meant the surface oriented on the side of the access opening and facing the other opposite section, and by external surface, the surface opposite to the internal surface.
  • each profile 20, 21 comprises a notch 7 at right angles, extending along the profile 20, 21.
  • the notch 7 extends over the entire length of the profile 20, 21.
  • the notch 7 thus takes the form of a longitudinal groove with a right-angled section similar to an "L" profile.
  • each profile 20, 21 has a notch 7 arranged to define a shoulder having a horizontal bearing surface 8 defining a horizontal bearing plane oriented towards the ceiling 4.
  • the bearing surfaces 8 of each of the profiles 20, 21 extend in the same plane parallel to the plane of the ceiling 4.
  • the panel 3 is sized to rest on the horizontal bearing surface 8 of each section 20, 21.
  • it has a transverse width greater than the transverse width "D" of the ceiling access opening. , which, in the illustrated embodiment, corresponds to the distance D separating the free edges facing the shoulders.
  • each shoulder has a horizontal bearing surface having a width greater than or equal to 5 millimeters.
  • This has the advantage of limiting the shadow cast on the canvas 5 when the panel 3 carried by the profiles 20, 21 is a light panel. Given the narrowness of the shoulders, the panel 3 rests on them for only a few millimeters.
  • wedging means 10 are placed on the shoulder of each of the profiles. 20, 21, between a lateral edge 30 of the panel 3 and a vertical stop face 9 delimiting the notch 7.
  • each notch 7 is delimited by a horizontal support surface 8, and a vertical support or stop surface 9.
  • each wedging means 10 consists of an elongated wedging bar 10A, 10B.
  • Each wedging bar is for example an elongated rectilinear bar of rectangular or square section.
  • the wedging means 10 are appropriately sized.
  • Each wedging bar 10A, 10B is thus a removable insert component which can be placed in an associated notch 7.
  • each wedging bar comprises at least one flat lower surface 11 which is able to rest vertically on an associated horizontal support surface 8.
  • Each wedging bar is also delimited by two opposite vertical side faces 12 and 13.
  • the external vertical side face In position in a notch 7, and after mounting the panel 3, the external vertical side face is opposite or in contact with a vertical surface 9, while the internal vertical face 13 is opposite or in contact with a side edge 30 of the panel 3.
  • the installation of the panel 3 on the supporting structure 2 is carried out as follows (the movements implemented for the purposes of installing the panel 3 are represented by arrows in solid lines).
  • first wedging means constituted by a first wedging bar 10A are installed in the notch 7 of one 21 of the profiles 20, 21, on the corresponding horizontal bearing surface 8 louse associated.
  • the panel 3 is then inserted into the space delimited between the ceiling 4 and the supporting structure 2 through the access opening, being introduced and placed at an angle as illustrated in figure 2a .
  • the installer can have a set of wedging means in the form for example of a set of wedging bars, possibly of different dimensions (length and cross section) that it implements according to the method described above.
  • each panel 3 can be formed by several elements, for example tiles, adjacent, but all of the same transverse width.
  • each wedging bar can be in a single piece over the entire necessary length, or in several elements placed adjacent and in the extension. longitudinal from each other.
