Definitions

  • the invention relates to insulating panels for roofs and more particularly to panels designed to respond to the problem of insulating waterproofing support for flat or low-slope roofs, with metal frame, wood or concrete.
  • These panels are formed of a felt or mattress of mineral wool, rock or glass, and of a coating for example a glass veil impregnated with bitumen, the coating being intended to receive at least one layer of a material d sealing.
  • These panels are fixed directly to the ground or the roof framework, generally by gluing when the surface to be covered is flat, or by mechanical fixing, in particular with screws and washers, when it is a pose on a framework. metallic or wooden.
  • the panels are coated with at least one sealing layer, generally a bituminous coating stickable with bitumen or weldable by flame heating.
  • Document US-A-4 766 024 describes an anchoring of the waterproofing coating deposited on site on a perlite panel provided with a layer of flame-protective coating, the panel with its coating layer being formed by a papermaking process then provided with recesses for the subsequent anchoring of the waterproofing coating on the site.
  • the invention provides an insulating panel making the reliability of the roof less dependent on scrupulous compliance with the installation conditions.
  • the invention provides an insulating panel having a reinforced adhesion between the mineral wool mattress and the waterproofing support coating, in particular providing better resistance to tearing or peeling of the cover in the event of severe storms.
  • the panel according to the invention comprises a mattress or felt of mineral wool having on its surface intended to receive the waterproofing support coating, recesses forming anchor points for the adhesive serving to adhere the waterproofing support coating to the felt. before the panel is put on site.
  • the recesses according to the invention must be large enough in section and in depth to allow satisfactory anchoring, that is to say resistant to different shear forces. Indeed, the plaintiff realized that the tearing of the cover in the event of a severe storm was due, in particular, to a weakening of the adhesion between the covering and the mattress during the realization of the insulation, due to the shear forces to which the panel is subjected when the applicator steps on it, which is generally the case when making the seal.
  • the recesses must not, however, be too large, in particular with respect to the thickness of the mattress, in order not to create points of mechanical weakness in the panel, or else in order to avoid a loss of qualities. insulation.
  • the recesses have a depth of between 5 and 10 mm.
  • the sectional shape of the recesses can be very varied. It can be squares, rectangles, circles or other geometric shapes, making it possible to anchor the glue and therefore the coating.
  • the recesses can advantageously be made by punching the panel.
  • the shapes of the recesses then obviously depend on the shapes of the punches.
  • each recess In addition to the shape of each recess, the arrangement of the recesses with respect to each other is a characteristic of the panel according to the invention.
  • the recesses can thus be arranged along lines of very different shapes. However, care should be taken not to use provisions which could weaken the mechanical characteristics of the panels. With this in mind, it is preferable to avoid a layout following a straight line parallel to the short side of the panel.
  • the cross-sectional area of the recesses is preferably within a determined range, and depends on the desired gripping forces and the adhesive used, this preferably being bitumen as in the case of known panels and for the same reasons which made it its selection: reduced cost, ease of application, compatibility with the sealing coating, etc.
  • the surface of the recesses is advantageously between 0.2 and 2 cm2.
  • the ratio p / S of the depth (p) of a recess on its average section (S), expressed in unit mm / mm2 is generally less than 0.3 unit and preferably less than or equal to 0 , 1 unit.
  • the ratio of the surface of the recesses to the total surface of the panel is between 0.05 and 0.15.
  • the panel covering may consist of a sheet or a veil, preferably a glass veil, impregnated with bitumen or another glue (adhesive) which can be housed in the recesses or anchoring points provided on the mineral wool mattress.
  • the coating can overlap two sides of the panel and comprise, in addition to the glass veil, a hot-melt film such as that described in the document already cited EP-A-0 109 879.
  • the invention also relates to a method and a device for the continuous manufacture of the insulating panels described above.
  • a rigid insulation blanket is made continuously of high density mineral fibers, by conventional methods for rock wool or glass wool, recesses are then advantageously created by punching the surface intended for receive the glued coating, in order to form anchoring points regularly distributed over the surface for the glue used for gluing the coating, the glue and the coating are then applied to the face provided with the recesses.
  • One of the advantages of punching compared to other techniques for producing the recesses is its simplicity of production. Another advantage is that it does not generate dust compared to machining the mattress.
  • the adhesive is applied to the mattress simultaneously with the covering. This is particularly the case when the coating uses bitumen as an adhesive and is impregnated with it before it is applied to the mattress.
  • the coating which is applied continuously has a width corresponding to the width of the mattress increased by a little less than twice the thickness of the latter, which allows partial overlap on both sides of the panel.
  • the coating may advantageously include a sheet of plastic material called separation as in the case of the panel described in EP-A-0 109 879 already cited and whose description is incorporated here by this reference.
  • the invention also relates to a device for implementing the method and manufacturing the panel. insulating.
  • the device comprises the known manufacturing means for producing the insulating panel, that is to say a fiberizing device with incorporation of the binder at the time of fiberizing, a conveyor receiving the fibers, means bringing the mattress to the thickness desired and an oven for the polymerization of the binder, means for supplying the coating and its bonding to the underside of the panel, cutting means.
  • a system arranged between the oven for the polymerization of the binder and the coating bonding station which comprises a stamping roller rotating on its axis at line speed, projecting bosses or punches distributed over its periphery, and plumb with, above the conveyor, means making it possible to apply constant pressure to the mineral wool felt to keep it in contact with the stamping roller, these means advantageously being a roller presser rotating on its axis.
  • the stamping roller rotates freely on its axis while the pressing roller is motorized at line speed.
  • the stamping roller can be motorized.
  • Means for adjusting the height of the rollers make it possible to vary the penetration of the punches in the mineral wool according to the desired depth for the recesses thus created, which, as indicated previously, may advantageously be between 5 and 10 mm.
  • This insulating panel can be used for the insulation of flat or slightly inclined roofs.
  • the fixed panels are coated on site with a waterproof coating.
  • the waterproofing coating can be formed from a glass veil impregnated with adhesive, preferably bitumen.
  • a suitable glass veil can be based on insulating glass fibers or so-called textile fibers, obtained by the dry or wet method. This veil can be reinforced with longitudinal reinforcing glass strands.
  • the coating can also be a composite formed of a glass veil and a grid reinforcing the tear resistance of the veil, the whole being impregnated with bitumen.
  • the insulating panel according to the invention has very good resistance when it is subjected to trampling forces, and in particular the adhesion between the felt and the coating remains high, compared to an insulating panel of the same composition, but without dots. anchor.
  • FIG 2 there is shown a device for punching the panels. This device is placed between the oven (not shown), in which the felt, in form of a continuous strip, stiffens by polymerization of the binder and the coating application station on the underside of the panel.
  • the felt 10 arrives at the punching station 11 after cutting and possible machining of the strips 12, 13.
  • a stamping roller 14 which can rotate freely around its axis 15, provided on its periphery with punches in the form of a pyramid trunk with rectangular base 16 placed along lines 17 in the form propeller.
  • a pressure roller 18 motorized at line speed is disposed in line with this stamping roller.
  • This pressure roller 18 is supported at its ends 19 and 20 by two bent arms 21, 22 mounted to pivot at the elbows 23, 24 around axes 25, 26 carried by bearings 27, 28 on a frame 29 and connected to the rods 30, 31 of two jacks 32, 33 by their ends 34, 35.
  • the two jacks are mounted articulated around axes 36, 37 carried by the frame 29.
  • the device Downstream of the stamping roller, the device comprises a roller 38 allowing the application of the coating 39 soaked in bitumen 41 on the underside 40 freshly punched of the felt 10.
  • the anchoring according to the invention of the covering which will serve as a support thereafter on site for the waterproofing covering, by being produced on an industrial manufacturing line ensures the reliability of the insulation system, in contrast to an anchoring waterproofing coating directly in the panel produced on site as described in document US-A-4,766,024.
