Definitions

  • the present invention relates to a method of manufacturing a double-glazed panel such as a window sash or French window or a fixed bay window.
  • the glazing positioning operation is difficult to perform with all the desired precision, and it is necessarily followed by the installation of shims of variable sizes that the operator selects and places on the sides of the frame in the necessary places, so to make up for the play inevitably created by the installation and for the double glazing to give rigidity to the leaf.
  • a second layer of this product is placed on its upper face and approximately opposite the first layer of mastic.
  • the glazing bead, and the assembly thus formed is then placed in a press which secures the various elements thereof by crushing the putty.
  • the glazing bead is then fixed to the frame, generally by nailing or screwing.
  • the object of the present invention is to remedy these drawbacks by proposing a method for producing a double-glazed panel which combines the advantage of technically superior results, in particular in terms of sealing, with that of authorizing automation. of the production line.
  • the present invention thus relates to a method of manufacturing a double-glazed panel which is essentially characterized in that it consists in using a double-glazed window whose external seal is made in situ, in at the same time as its assembly to the carpentry frame, by casting or injection, between the rebate bottom and the spacer separating the two sheets of said double glazing, of a liquid mixture formed of at least two constituents giving rise to a reaction of polymerization at room temperature, leading to the formation of a seal which ensures both the tightness of the panel and its seat setting.
  • the two glass sheets joined by a spacer placed a short distance from their periphery are arranged in the rebate of the chassis laid flat before injection or pouring of the liquid mixture which fills all the space available between the rebate and the spacer.
  • the glazing bead is then laid and fixed either by conventional means or by gluing.
  • the mixture used in the process according to the invention to produce both the tight seal of the double glazing and that joining it to the joinery can consist of any liquid mixture capable of giving rise to a polymerization reaction at room temperature, however, it advantageously consists of the mixture, produced at the time of use, of an isocyanate and a polyol, leading to the in situ formation of a polyurethane.
  • the mixture used is such that the crosslinking of the polyurethane takes place within a period of time of the order of a few tens of seconds.
  • the starting mixture can be that constituted by a polyol whose viscosity is from 9 to 10,000 mP / s at 20 ° C and the density at the same temperature of 1.45 and a 4.4′- diphenylmethane diisocyanate with a viscosity of 180 to 200 mP / s and a density of 1.22 at 20 ° C., the weight ratio of the mixture being 100 parts of polyol per 25 parts of isocyanate.
  • the mixture injected within a few seconds, gives a joint whose physical characteristics at 20 ° C are as follows: - gel time: 12 s. - setting time: 2 min 30 s to 3 min 30 s. - shear stress: 8N / mm2. - bonding value: 30 to 40 N / cm.
  • the method according to the invention offers the possibility of producing double glazing in situ, first by laying the first sheet of glass in the frame, then by placing the spacer. , followed by the installation of the second sheet of glass. The liquid mixture is then poured or injected so as to create the seal for the double glazing and to secure it to the frame in a leaktight manner.
  • the method according to the invention also makes it possible to manufacture a glazed panel from its various separate constituent elements, by assembly in situ, which constitutes another advantage compared to existing methods, in which the already formed double glazing is inserted into the previously constituted chassis.
  • This advantage leads to the additional advantage of authorizing the removal of the glazing bead, which can be replaced by a flexible seal fixed to the frame by gluing.
  • a flexible seal may advantageously have a tee profile so as to ensure its best attachment to the seal, being in this case placed immediately after pouring of the liquid mixture which constitutes the latter and in which it is partially immersed.
  • This flexible seal can be made of any suitable material such as metal or plastic, and in particular aluminum, polyvinyl chloride or rubber.
  • FIG. 3 we find the same elements as in FIG. 2, except for the glazing bead 5, which is replaced by a gasket 26 with a tee profile, the lower face of which comprises a lip 27 intended to be immersed in the liquid mixture which forms the seal 3 before its polymerization, so as to ensure effective joining of said seal 26, which can be made of any suitable material such as metal or plastic.
  • the method according to the invention also has the advantage of authorizing a variety of methods of assembling the elements constituting the glazed panel, making it possible to start from either an already formed chassis either of the various parts which constitute it, and either of a double glazing already formed, close to the seal, or of the sheets of glass which constitute it.
  • the process according to the invention combines with these advantages that of not requiring a pressing operation to securing the assembly, and allowing the installation of double glazing of significant thickness in the usual rebates, the fact that the glazing bead no longer serves to ensure the mechanical strength of the assembly, being limited to a finishing role, and being able to be replaced by a flexible plate or rod fixed to the chassis by gluing.
