Definitions

  • the present invention relates mainly to a method for producing plates, mainly for suspended ceilings, in particular thermal and / or sound insulation plates, to fire plates as well as to a method for using said plates.
  • partitions are produced, in particular horizontal partitions constituting false ceilings simultaneously forming a surface, advantageously planar, and ensuring the desired acoustic, thermal, and / or fire insulation. It is understood that non-planar surfaces, for example honeycombed, to improve sound insulation or ribs reinforcing the plate, facilitating the handling and / or demolding of the plate, do not depart from the scope of the present invention.
  • plaster is used, in particular reinforced with fibers, for example glass fibers, and expanded materials.
  • a partition comprising these substances provides better insulation, both acoustically and thermally, while having a lower weight.
  • the plates for suspended ceilings according to the present invention comprise connectors for joining by gluing of the adjacent plates.
  • These connections are advantageously in the form of rebates comprising means for leveling two successive plates independently of the presence of the adhesive.
  • the rebate forms a baffle ensuring excellent acoustic, thermal and / or fire insulation.
  • This insulation is further improved by a judicious choice of the adhesive ensuring the bonding of the plates.
  • Acoustic or thermal insulation is improved. This improvement is particularly important in the case of suspended fire-resistant ceilings according to the present invention. Indeed, any destruction by the flames of a junction of two plates risks causing the destruction of the plate suspension means and, by their fall, canceling their firebreak role.
  • a fire barrier must be able to guarantee that it can withstand a fire for a given period of time, for example 30 minutes, 1 hour or 2 hours. Regardless of the specific qualities of the plates according to the present invention, the fire-resistant quality can only be guaranteed if the installation has been carried out correctly. However, the building industry uses in particular unskilled and / or poorly motivated labor. This can result in poor implementation of the fire plates which, in such a case, would no longer guarantee the desired resistance to fire.
  • a method of installing suspended ceiling plates is used which is particularly simple and insofar as it is implemented, without compromising the side. plate firebreak.
  • the method of implementing plates according to the present invention comprises an assembly by rebates.
  • This method comprises the steps of fixing in the ceiling and in the plate of anchoring elements connected by suspension means.
  • the suspension means are surrounded by two half-shells, for example made of plaster, themselves filled with plaster. More generally, for example, the same material as that of the plates is used. The use of the same thickness makes it possible to comply with certain standards on fire-resistant materials.
  • the method according to the present invention makes it possible to triple the laying speed per square meter.
  • modifications can be made such as for example a displacement of a partition or a cutout with a view to installing an air vent or a lighting device.
  • the subject of the present invention is also a plate for a suspended ceiling produced by the method according to the present invention, characterized in that it comprises fittings in the form of rebates intended to be glued for assembly with an adjacent plate and fixing means. at the level of two successive plates regardless of the presence of the adhesive.
  • the present invention also relates to a method, characterized in that it comprises a step consisting in placing two half-shells, in particular comprising plaster, filled with fresh plaster, around the suspension means connecting the anchor point of the plate by means of anchoring the ceiling.
  • Figure 1 we can see a particularly advantageous embodiment of a plate according to the present invention intended for the realization of a suspended ceiling.
  • Figure 1a is a top view;
  • Figures 1b and 1c are sectional views of a plate or slab according to the invention.

  • the upper and lower faces of the plate 1 bear the references 5 and 6.
  • Each plate comprises at minus a cornice or upper projection 3 and a lower projection 2.
  • the projections 2 and 3 of the adjacent plates are intended to make a connection by forming a rebate.
  • the upper and lower projections 3 and 2 are glued to each other with an adhesive having the desired qualities of insulation and / or firebreak.
  • an adhesive having the desired qualities of insulation and / or firebreak.
  • a plaster tile adhesive is used, for example that sold under the brand "FUSCO”.
  • Means 4 prevent the thickness of the glue from making an excess thickness at the fittings.
  • the means 4 are advantageously spacers making contact between two successive plates 1 while leaving a space for the adhesive. Even at the level of contact between two plates 1 at the level of the spacers 4 there is no excess thickness of adhesive.
  • the presence of glue is avoided at the level of the spacers 4, for example by an adequate choice of the geometry of the spacers.
  • the contact surface between the spacers 4 and the corresponding contact projection is substantially zero.
  • spacers 4 are used which have a substantially triangular or trapezoidal profile, advantageously semi-cylindrical.
  • the spacer 4 is disposed on the upper projections 3.
  • account is taken of the habits existing on the site on which the adhesive is deposited on the plates 1 already in place. So there is less risk that the glue will dry on the spacers 4.
  • the plates 1 comprising spacers on the lower projections or on the lower and upper projections do not depart from the scope of the present invention.
  • the plates according to the present invention advantageously include projections 2 or 3 on all sides.
  • these projections make it possible to better distribute the weight, and above all to form baffles improving the desired insulation at all of the plate connections.
  • the plate 1 is rectangular.
  • the upper projections 3 are formed on a large side and a small side allowing the normal progression of the installation according to the habits of the sites. It is understood that the use of plates having another shape, such as for example square, triangular or hexagonal does not depart from the scope of the present invention.
  • the plate includes anchoring means 7.
  • the anchoring means 7 are not, for example, metal parts placed in the upper face 5 of the plate 1 at the time of its production and whose ends protrude flat. On a building site, the anchoring means 7 are unfolded to allow them to be used for hanging the plates.
  • the attachment means are made of a material which is not likely to be corroded, such as for example galvanized steel.
  • the hooking means are regularly spaced along the length of the plate close to the side comprising a lower projection 2.
  • the distribution is advantageously such that the longitudinal spacing between two successive anchoring means 7 in the laid slab is constant.
  • the anchoring means 7 support the part of the plate 1 comprising the lower projection 2.

  • the plates having anchoring means on more than one side do not depart from the scope of the present invention.
  • the plates 1 according to the present invention are not exactly flat.
  • the lower surface 6 intended for receiving the paint is perfectly flat, so we create flawless ceilings.
  • the plates 1 according to the present invention can rest one on the other only by their ends. Contacts are avoided by local extra thicknesses 21 at the ends and / or by a profile of the slightly concave upper face 5. This face is not visible, the concavity is not annoying.
  • FIG 3 we can see an example of arrangement of spacers 4 on the plate according to the present invention.
  • the illustrated spacers 4 are of the semi-cylindrical type having the advantage of being easily achievable while being of great resistance.
  • the spacers 4 have for example a width of 9 mm and a thickness d1 of 3 mm.
  • the spacers 4 are for example 146 mm apart.

  • a protective means 11 is for example made up of two plaster half-shells (or with the same materials as those of the plate).
  • each half-shell 11 is filled with a binder 12, for example with plaster.
  • the presence of the binder 12 prevents the descent of the plate 1 in the case where the suspension means 14 is not properly tensioned.
  • the anchoring means 7 comprises means 15 increasing the lift of the anchoring means 7 in the binder 12.
  • the means 15 comprise for example spikes, or on the contrary substantially flat horizontal surfaces.
  • FIG. 7 one can see a flowchart illustrating an example of a method for producing plates according to the present invention.
  • the production method according to the present invention mainly comprises a set of steps 100 consisting in determining the constitution and the geometry to be used to obtain the desired insulation and a step 200 consisting in checking the technical and economic reliability of such a plate and ensuring its manufacture.
