Definitions
- the invention relates to seals for a building element. These joints are usually intended to fulfill at least one of the following two functions: they can ensure the intrinsic tightness of each of the construction elements, when this is necessary in view of the structure of these. They can also be used to seal the assembly of a plurality of adjacent elements forming a wall.
- the invention relates more particularly to seals for insulating wall panels, sometimes called “sandwich” panels, and which consist of generally metallic walls delimiting a cavity filled with a material with high insulating power on the plane.
- Such panels are interesting in that they combine rigidity, lightness and thermal / acoustic performance.
- the sheets are cut transversely to obtain panels of the desired length, panels which can then be assembled side by side to form a wall, a partition, a ceiling, ...
- the joints placed on the sides which initially served to contain the expansion of the foam inside the cavity defined by the metal sheets, therefore to ensure the tightness of this cavity, again serve to ensure the tightness at the level of the zones jointing between adjacent panels, in particular with respect to humidity, and to avoid the creation of a thermal bridge when these panels are used outdoors, which is the most frequent case.
- the seals to ensure these different functions, have to fulfill certain criteria. Thus, they have to have good flexibility and good compressibility, and this is the reason why they are usually themselves based on polymer foam. They also have to allow a good “hooking”, a good adhesion with respect to the foam of the cavity of the panel with which they are brought into contact, which can prove to be awkward if they offer too much external surface. smooth, which is sometimes the case when they are closed cell foam. To remedy this, two solutions can be envisaged, but each having their drawbacks: the surface of the joint intended to be in contact with the foam of the panel can be made rougher, by abrasion or by resealing the foam of the joint in its thickness, but these methods are complicated and generate dust or waste which must then be managed.
- the seal adhesive can also make the seal adhesive, using an acrylic type glue for example.
- the presence of certain plasticizers in the joint foam can reduce this adhesive power.
- the adhesives are combustible, which can weaken the usually high fire resistance of the panels. Indeed, the strips are capable of considerably delaying the progression of the fire, the only areas of jointing being their "weak point", because the joints can be directly exposed to the flame, and the fire may risk spreading laterally, through them to the foam of the panels.
- the object of the invention is to design seals for construction elements which are better, in particular overcoming the drawbacks mentioned above, by improving their fire behavior without degrading their ability to adhere to the elements on which they have to be deposited.
- the subject of the invention is a seal based on flexible / compressible polymer, in particular intended to ensure the proper sealing of a building element and / or the sealing between two adjacent building elements, elements of the panel type. of wall.
- This seal is designed so as to be provided, at least on its surface intended to be brought into contact with said element, with a surface coating of a non-combustible material and / or retaining its integrity at high temperature.
- this surface coating constitutes an effective barrier to the propagation of fire in the panel via the joint, which has two major advantages.
- the panels are ignited one after the other significantly by a chimney effect at their weak point, that is to say their jointing areas.
- this polymer was hitherto chosen in order to be qualified as "hardly flammable" according to standard DIN 4102, which corresponds to the so-called B1 class.
- the surface coating is chosen from at least one material belonging to the following group: glass, ceramic, metal, carbon, graphite, aramid.
- these materials are in fact used in fibrous form, the fibrous material being woven, or nonwoven, but agglomerated using a binder.
- This fibrous material is preferably composed of threads themselves made up of unitary filaments.
- these unitary filaments usually have a diameter of between 5 and 12 micrometers, in particular around 7 to 9 micrometers. They are then assembled in tens, twisted or not, to become yarns of a linear weight advantageously between 10 and 150 tex (1 tex corresponding to 1g / 1000m of yarn), in particular about 22 or 68 tex.
- a fibrous material lies in particular in the fact that it makes it possible to manufacture a surface coating having a certain surface roughness, greatly facilitating the “attachment” of the joint to the construction element, and, in particular in in the case of an element in the form of an insulating panel with polymer foam, the "hooking" of the joint against the expanding foam. This eliminates the need for adhesive on the surface coating, which is expensive and often poses problems of resistance to high temperature.
- a fibrous material also has the advantage, in particular in the case of a fabric, of being able to easily conform to any joint surface, whether it is flat, curved or has angles.
- one of the preferred embodiments of the invention for this surface coating is a fabric-based or veil-based coating of glass fibers, which is made of a material which is both very resistant to temperatures of the order of 500 ° C and of a texture offering flexibility and a light surface roughness very favorable to a good adhesion to foam of expanded polymer of the polyurethane type.
- a surface coating with a thickness of between 50 and 250 micrometers, in particular approximately 100 to 200 micrometers, range of thicknesses sufficient to obtain the effect of slowing down of propagation on fire desired.
- a surface coating of a grammage between 50 g / m 2 and 300 g / m 2 , preferably around 100 to 200 g / m 2 is preferably chosen, grammage corresponding to a coating sufficiently dense to give it its role as a barrier to the spread of fire.
- the seal according to the invention in addition to the surface coating, is based on a polymer preferably chosen from a flexible foam of at least one of the following polymers: polyvinyl chloride PVC, polyurethane PUR, polyethylene PE, terpolymer of polyethylene and polypropylene EPDM, silicone, polypropylene PP, rubber, styrene-butadiene-nitrile polymer SBN, neoprene, possibly treated polymers, and in particular plasticized to obtain the desired flexibility.
- polymers preferably chosen from a flexible foam of at least one of the following polymers: polyvinyl chloride PVC, polyurethane PUR, polyethylene PE, terpolymer of polyethylene and polypropylene EPDM, silicone, polypropylene PP, rubber, styrene-butadiene-nitrile polymer SBN, neoprene, possibly treated polymers, and in particular plasticized to obtain the desired flexibility.
- the foam texture has the advantage of giving the polymer a high compressibility, which is what is sought when the joint is “wedged” between two construction elements, and must compress more or less in order to adapt to the distance between them, taking into account the manufacturing tolerances of said elements. It is indeed not uncommon for such seals to have a compressibility in their thickness of at least 30% or 50% and more.
- the polymer can advantageously be treated in order to improve its resistance to high temperature and to fire, in particular by incorporating into it an flame retardant additive.
- This additive can in particular be chosen from at least one of the following compounds: antimony oxide Sb 2 O 3 , hydrated alumina or aluminum hydroxide, zinc borate, brominated hydrocarbon or chlorinated paraffin. Details on these compounds and their proportion relative to the polymer can be found, for example, in US patent US-4 806 162.
- the polymer of the seal according to the invention can also itself comply with DIN 4102, in particular belonging to class B1, which reinforces the fire barrier effect of the seal. conferred by its surface coating.
- One of the preferred embodiments of the invention relating to this polymer consists in choosing a polyvinyl chloride foam plasticized to which was added one of the additives mentioned above and in particular obtained from plastisols and blowing agents, for example based on nitrogen products such as sulfohydrazides or azo-dicarbonamides.
- plastisols and blowing agents for example based on nitrogen products such as sulfohydrazides or azo-dicarbonamides.
- This type of foam is indeed advantageous in terms of compressibility, it has an adequate density of around 100 kg / m 3 and the manufacturing process is well controlled.
- the density of the joint is preferably chosen to be around 80 to 150 kg / m 3 . If it is a foam, it may be closed cell. In case the cells are at least partially open, it is better to plan to impregnate it with a moisture repellant.
- the seal according to the invention can have extremely varied shapes. Usually, it is in the form of a continuous ribbon, the section of which has been calibrated, a section which may in particular have the shape of a quadrilateral such as a square, rectangle, trapezoid, parallelogram. But its section can also be chosen round or oval.
- This polymer preferably based on foam, can thus be obtained directly at the desired size by an extrusion technique.
- the surface coating is then associated with it once the extrusion is completed, in particular by using a device of the conforming type. It may also be necessary to use an adhesive to facilitate bonding between the foam and its coating.
- the polymer when it is particularly foam-based, can also be produced in the form of a continuous sheet, by passing through an oven at suitable pressure and temperature, on a support which is preferably constituted by the surface coating. itself resting on a conveyor. The ply, once the expansion of the foam is complete, can then be cut to obtain the desired size, and in particular width joint. With this type of process, the manufacture of the foam and the association with the surface coating are carried out in a single step, the foam "hanging" on the coating without the need for adhesive.
- the joint according to the invention can be provided with a first surface coating based on fibrous material on its surface intended to adhere to the panel - in order to facilitate the attachment of this joint - and with a second surface coating on at least one part of the rest of its outer surface, second coating which may be in the form of a continuous film, in particular metallic.
- this second coating is not intended to have to adhere to a foam of an insulating panel, it can therefore have a very smooth surface without disadvantage.
- gaskets according to the invention is particularly recommended for sealing construction panels comprising essentially metallic walls delimiting a cavity comprising a thermal and / or sound insulation material of the foam type. rigid polymer, in particular to improve fire resistance.
- the seals of the invention are preferably placed on at least part of the "joint" area of the walls of such a panel, sometimes called a "sandwich" panel.
- the panels 1 shown very schematically in Figure 1 are arranged in a vertical plane to form an exterior wall of the building.
- Each panel has the shape approximately of a parallelepiped with a thickness of approximately 60 to 100 mm, a width of approximately 2 to 3 m and a length which can range in particular from 3 to 16 meters and more. They are assembled along a vertical plane to form a building wall (and mechanically fixed using a metal frame not shown).
- Each panel 2, 3 is made up of flat or profiled sheet metal walls, in particular of steel and 0.6 to 0.9 mm thick, delimiting a cavity 4 filled with rigid polyurethane foam 5 classified B1 or B2 in terms fire resistance according to DIN 4102.
- FIGs 2a and 2b detail, still very schematically, the manufacture of such panels 1, each of the opposite lateral edges of which is identified by the letter A and the letter B respectively: sheet metal sheets 2, 3 arranged one on the other and kept at a distance d pass on a conveyor, with, at the level of the joint zones 6 between the two strips, a free space.
- the reaction liquid based on polyurethane precursors and suitable expansion agents is injected, continuously, between the two strips 2, 3.
- rollers presseurs7 come, on side A, to press the seal 8, 9 according to the invention which, to do this, is unwound gradually.
- the seal 8, 9 is then placed so that its surface coating 8 is against the joint area 6 and the free space that it defines.
- the pressure of the pressure rollers 7 is maintained over a length sufficient for the foam 5 of the panel 1 to adhere to the surface covering 8, and thus fixes the seal 8, 9 in position.
- the sides A and B have profiled edges so as to define a female part (side A), and a male part (side B), which will allow to easily assemble the panels later by fitting them one inside the other.
- cutting tools (not shown) cut the strips transversely to their axis of travel on the conveyor in order to obtain the finished panels at the desired length.
- the seal 8.9 used is here of rectangular section, (width 45 mm - thickness 6 mm) and is provided on one of its faces with a fabric 8 of glass 100 micrometers thick, with glass wires of linear weight 22 tex made up of the assembly of unitary filaments of 7 micrometers in diameter and a grammage of 107 g / m 2 .
- Good results are also obtained with slightly thicker fabrics, for example around 180 micrometers and / or slightly denser, for example from 200 to 210 g / m 2 obtained in particular from slightly linear yarns. higher, for example about 70 tex or more.
- This joint is based on plasticized PVC foam 9, and it has a compressibility rate in its thickness of at least 50%. Containing fire-fighting additives, this foam 9 is classified B1 according to DIN 4102.
- the seal was manufactured in the following way: on the glass fabric 8 having the predefined characteristics and deposited on a conveyor, a reaction liquid is poured based on plastisols and ad hoc expansion agents, then the assembly is passed through an oven at adequate pressure and temperatures, the plasticized PVC foam 9 then gradually expands onto the glass fabric 8 while strongly adhering to it.
- This foam also contains fire-fighting additives, comprising antimony trioxide at approximately 1.25% by weight, zinc borate at approximately 1.25%, and chlorinated paraffin at 4% by weight relative to the weight of PVC, paraffin being chosen in particular from the range of products sold under the name of CERECLOR by the company "Imperial Chemical Industries PLC".
- the sheet of foam obtained is cut by cutting tools of the circular saw type arranged in a row above it, in the direction of its axis of travel on the conveyor, in order to obtain a plurality of ribbons. rectangular section desired, ribbons then wound before use as previously described.
- This manufacturing method is very advantageous in terms of yield and manufacturing cost.
- techniques of the extrusion type of the joint directly to the desired size are also of interest, insofar as they can make it possible to obtain seals 8, 9 with more elaborate sections, in particular circular sections.
- Figure 3 shows in section the jointing area between two panels 1 as assembled in Figure 1: the joint 8, 9 is compressed by at least 30% in its thickness, the sides B of the first panel coming to fit together in side A of the second panel, with a certain "flapping" in fact inevitable, given the manufacturing tolerances of this type of panel.
- the seals 8, 9 are directly exposed to the flames, hence the importance of improving their fire behavior to prevent the fire from spreading from the foam 5 of a panel 1 to the foam of an adjacent panel via the joints 8, 9, the only “weak points” of these structures since the sheet metal strips 2, 3 of the panels 1 are moreover very effective in delaying the progression of the fire.
- the glass fabric 8 of the seals 8, 9 according to the invention has proved to be excellent for slowing the progression of fire, and its texture has proved to be very advantageous since it also improves the foam adhesion 5 of the panel 1 / joint foam 9, without requiring treatment of joint foam and / or addition of adhesive.
- joint foam itself is treated with fire-fighting additives reinforces the very good fire resistance of the joints according to the invention.
- a material other than glass as a non-combustible or low-combustible material; it is also possible to modulate the thickness and grammage of the surface coating, and cause this coating to cover several of the faces of the joint instead of just one, in particular the lateral faces of the joint, or even all of its external surface.
- the dimensions of the joint can also vary considerably according to the needs, with, in the case of joints of rectangular section, thicknesses of for example 3 to 20 mm and widths adapting to the dimensions of the panels to be joined, for example from 10 to 100 mm.
