Definitions

  • the present invention relates to the field of construction and more precisely to the field of load-bearing and / or structuring masonry and related masonry constructions or assemblies.
  • the masonry construction elements are assembled to form sets such as walls, etc. by means of mortar.
  • This type of binder has several drawbacks. Indeed, to prepare traditional masonry or thin joint mortar, often based on hydraulic binders, you need equipment and trained labor, the preparation time is long (about 1 hour), not to mention the time. installation, drying time (7 to 28 days). In addition, this process requires the elements to be placed within a very short period of time of the order of a quarter of an hour, which corresponds to the working time after removal to ensure the assembly of the elements.
  • polyurethane foam in the face of bad weather and especially in windy weather, the foam does not stay in place on the construction element and bonding becomes impossible.
  • the doses of polyurethane foam must be limited because polyurethane foam contains isocyanates (even in small quantities) which are often toxic and reactive compounds to be handled with care and whose vapors must be strictly avoided.
  • the object of the invention is to remedy all or part of the aforementioned drawbacks by proposing a masonry assembly devoid of binder containing isocyanates or without release of isocyanates and whose structure allows rapid and simple removal whatever the external conditions.
  • the assembly method of the construction assembly according to the invention has the advantage of being non-toxic by the use of a binder free of isocyanate or free of reactive isocyanates.
  • a binder in the form of gel or mastic is advantageous because during its application to the first construction element and in contact with air, a protective film encapsulating the composition of said binder can be formed. form.
  • This protective film makes it possible to maintain the integrity of the composition of the binder in its form and its chemical properties, whatever the external conditions.
  • the protective film pierces or breaks up, releasing the composition from the binder in order to allow adhesion of the first building element with the second building element.
  • this binder allows the installer to work in two ways, that is to say poses elements before or after the formation of the film and without exceeding the duration of hardening at the heart of the binder recommended by the manufacturer. , generally of the order of half an hour.
  • the term “binder” is understood to mean an element which is suitable for binding, for holding together various elements, for ensuring their cohesion or their union and which gives the bonding area of the elements to each other high mechanical qualities of adhesion, shear resistance and sealing.
  • gel is understood to mean a solid which can have properties ranging from soft and ductile to hard and brittle.
  • gels are defined as highly diluted entangled systems showing no flow when at steady state. In bulk, gels are mainly made up of liquid, yet they behave like solids thanks to their three-dimensional network entangled within the liquid. It is these tangles that give gels their structure (hardness) and contribute to their adhesion.
  • the term “mastic” is understood to mean a kind of plastic paste, obtained by mixing various synthetic or natural substances which give it certain mechanical qualities, in particular a very high viscosity.
  • the binder regardless of the form in which the binder is presented: gel or mastic, the latter has enhanced properties and in particular making it possible to give the bonding zone of the elements to each other high mechanical adhesion qualities, shear strength and sealing.
  • composition devoid of isocyanates is understood to mean a composition which is produced without isocyanate or else a composition which has a sufficiently high degree of purity so that no release of isocyanate vapor is released from all of the isocyanates. construction neither during nor after installation.
  • the binder is free before polymerization of products toxic to humans.
  • the chemical formulation of the non-toxic binder also makes it possible to guarantee the durability of the performance during the service life of the structure (of the order of 50 years) or even to improve it over time, unlike the hydraulic binders whose mechanical performance stabilizes at best.
  • the binder is does not release esters or derivatives of phthalic acid or alcohols or derivatives of alcohols.
  • the formulation of the binder is such that the notions of shrinkage and creep do not exist in the medium and long term, unlike cement-based hydraulic binders, of which we know the impact of these characteristics on the mechanical performance in the medium and long term.
  • the binder comprises a protective membrane in the form of a plate, pocket or bead encapsulating, as soon as it is applied, a core of active material, said protective membrane being configured to disintegrate or s '' incorporate in the active material so as not to screen the bonding.
  • the core of active material can be released from the protective membrane, for example by spraying water before fitting the construction element.
  • the membrane can be water soluble.
  • the protective membrane is liable to disintegrate or to pierce, thus freeing the core of active material, by applying pressure to the latter during the installation of the upper construction element or adjacent to said protective membrane.
  • the binder used can be of a composition similar or identical to the binder of the brand Fix'bric® or Opti'fix®.
  • the contact surface of the first construction element and / or the contact surface of the second construction element is at least partially planar.
  • the contact surface intended to be covered by the binder of the first construction element and / or the contact surface intended to be covered by the binder of the second construction element is at least partially in relief.
  • the consistency of the binder close to a gel or a mastic and the absence of shrinkage on drying makes it possible to absorb the difference in dimensional tolerances and roughness of the contact surfaces of the upper element with the two adjacent elements of the rectified elements while maintaining the mechanical properties in the main part or at the level of a junction with an accessory.
  • the relief may be a relief in the form of a fitting member.
  • the difference in flatness of the contact surface intended to receive the binder is less than or equal to 1 mm.
  • the binder is a non-hydraulic non-polyurethane binder.
  • the binder is an epoxy or acrylic or geopolymer or mono or two-component or organic gel.
  • the binder is a polyurethane.
  • the first construction element and / or the second construction element is cellular.
  • the binder is applied only to the horizontal faces of a construction element at least partially, whether the construction element is solid or honeycomb, which makes it possible to reinforce the structure mechanically. compared to horizontal forces such as earthquakes.
  • gluing only the horizontal faces makes it possible to adjust the quantity of binder as a function of the forces calculated to optimize the consumption of binder on site or in the factory.
  • the European construction regulations such as Eurocode 8 impose in a seismic zone the realization of vertical joints when the assembly is based on traditional hydraulic binders, the assembly system according to the invention makes it possible to dispense with this thanks to the mechanical properties of the binder.
  • the binder can be applied in spots or in a bead extending all the way along the side of the building element, or in a bead extending partially along the side of the element. construction or over the entire surface of the side of the construction element.
  • the binder cords can be positioned on the outer edges and / or on inner portions of the contact surface or in the cavities formed by the relief (s).

  • each construction element can be made of terracotta, concrete, lightweight aggregate concrete or expanded clay, composite concrete, concrete based on plant fibers, cellular concrete, PVC, aluminum, wood, etc. ...
  • the method comprises a step of placing an intermediate element on the binder after application of the binder on the first construction element.
  • an intermediate element advantageously makes it possible to increase the mechanical performance (shear for example) or the acoustic performance of the construction assembly.
  • the assembly method according to the invention allows prefabrication in the factory of panels or walls or assemblies of great height and / or of large format.
