Definitions
- the present invention relates to a method of manufacturing a multiple glazing comprising a spacer frame fixed between two sheets of glass.
- the invention also relates to a facility for manufacturing multiple glazings.
- an insulating glazing unit (or multiple glazing) can be obtained by joining at least one rigid spacer frame to the periphery of two sheets of glass using sealing beads, and by applying an outer sealing barrier on all the outer circumference of the spacer frame between the two sheets of glass.
- the sealing beads between each glass sheet and the spacer frame which are generally based on polyisobutylene (“butyl”), not only allow to pre-assemble the glass sheets with the spacer frame for the purpose of sealing the multiple glazing , but also to achieve a primary barrier of sealing to water vapor and gases.
- These sealing beads are conventionally deposited on either side of the spacer frame, on its side walls intended to be adjacent to the glass sheets of the multiple glazing unit, each sheet of glass being then pressed against the corresponding side wall of the spacer frame at level of the sealing bead.
- the deposition of the sealing beads on the spacer frame must be carried out in a dedicated station, which is located outside the main line of multi-glazing manufacturing including the glass sheet washing station, the sheet pressing station. glass on the spacer frame, the sealing station of the multiple glazing. During the pressing of the glass sheets on the spacer frame, the sealing beads previously deposited in the off-line station have had time to cool, which affects the quality of the primary sealing barrier. In addition, after the deposition of the sealing beads on the spacer frame, the latter is subject to several manipulations, manual or automated, which creates a risk of damage to the sealing beads located on either side of the spacer frame.
- the presence of defects in the sealing beads can lead to leakage of insulating gas present inside the multiple glazing, or the entrance of water vapor that condenses inside the multiple glazing, which impacts the quality and the durability of multiple glazing.
- the deposition of the sealing beads must also be performed after the assembly of the spacer frame, which requires implementation of the steps of manufacturing a multiple glazing successively, with limited productivity.
- the invention intends to remedy more particularly by proposing a method of manufacturing a multiple glazing which guarantees the obtaining of a good quality primary sealing barrier, which is favorable for the durability. multiple glazing, which improves cycle time and productivity for the manufacture of multiple glazing.
- the invention relates to a method of manufacturing a multiple glazing comprising at least three glass sheets and a spacer frame fixed between two outer glass sheets, the or each central glass sheet multiple glazing being received in an inner peripheral groove of the spacer frame, each of the two outer glass sheets being bonded to a side wall of the spacer frame via a sealing bead, characterized in that it comprises steps in which:
- a sealing bead is deposited on a peripheral portion of a main face of the glass sheet
- the spacer frame is assembled around the central glass sheet or sheets
- each outer glass sheet provided with its sealing bead is secured to a side wall of the spacer frame.
- the invention since at least one sealing bead of the multiple glazing is deposited on a glass sheet rather than on the spacer frame, the risk of degradation of the sealing bead is limited. Indeed, the sheet of glass, which is conventionally moved on a conveyor, is subject to little or no manipulation during the manufacturing process of multiple glazing.
- the deposition of the sealing bead on the glass sheet can be performed on a main line of manufacturing multiple glazings, upstream of a mounting station of the glass sheet on the spacer frame, the assembly of the glass sheet with the spacer frame can take place rapidly, in the still hot state of the sealing bead, which promotes the quality of the primary sealing barrier thus formed between the spacer frame and the glass sheet .
- glass sheet any type of substrate suitable for use in a multiple glazing. It may be a mineral glass sheet, especially a glass of oxide which may be a silicate, borate, sulfate, phosphate, or other. Alternatively, it may be a sheet of organic glass, for example polycarbonate or polymethylmethacrylate.
- a sealing bead is deposited on a peripheral portion of a main face of each of the two outer glass sheets, and each outer glass sheet is secured with its sealing bead. with a side wall of the spacer frame.
- a first sealing bead on a peripheral portion of a main face of a first outer glass sheet, which is intended to be connected to a first side wall of the spacer frame; depositing a second sealing bead on a second side wall of the spacer frame opposite the first side wall of the spacer frame; the first external glass sheet provided with its sealing bead is secured to the first side wall of the frame spacer; and securing the second outer glass sheet with the second side wall of the spacer frame provided with its sealing bead.
- the multiple glazing comprises at least three glass sheets and a single spacer frame fixed between two outer glass sheets, the or each central glass sheet of the multiple glazing being received in an inner peripheral groove of the spacer frame.
- a triple glazing thus comprises a spacer frame with a groove, two outer glass sheets being positioned on either side of the spacer frame and a central glass sheet being received in the groove of the spacer frame;
- a quadruple glazing comprises a spacer frame with two grooves, two outer glass sheets being positioned on either side of the spacer frame and two central glass sheets being each received in a respective groove of the spacer frame; etc.
- the spacer frame is assembled around the central glass sheet (s) of the multiple glazing unit.
- the central glass sheet or sheets of the multiple glazing are inserted into an open portion L or U of the spacer frame, with their edges received in a respective groove, then the assembly of the spacer frame is finalized by closing the open L-shaped or U-shaped portion around the central glass sheet (s) with one or two additional profiles that are attached to the L-shaped or U-shaped portion.
- the spacer frame assembly According to a second variant of the spacer frame assembly, four sections of the spacer frame are positioned on the four edges of the or each central glass sheet of the multiple glazing unit, by inserting the edges of each central glass sheet into the corresponding grooves of the profiles. then the profiles are attached two by two at their ends at the corners of the spacer frame.
- each groove of the spacer frame is provided with a lining for receiving a central glass sheet, in particular based on elastomer material such as ethylene-propylene rubber. diene (EPDM).
- the groove may have a width greater than the thickness of the central glass sheet.
- the liner serves to fix the central glass sheet in the groove, while compensating for any variations in thermal expansion of the central glass sheet. Unrestrained fixation of the central glass sheet in the groove is thus ensured.
- the reduction of the stresses applied to the central glass sheet makes it possible to reduce the thickness and the weight of this central glass sheet, compared to those used in the multiple glazings where the central glass sheet is fixed on the central glass sheet.
- periphery of a spacer frame instead of being received in a groove.
- the liner is advantageously configured to allow balancing by gas flow between the cavities of the multiple glazing located on either side of the central glass sheet.
- the manufacture of multiple glazing may involve depositing a sealing bead on a peripheral portion of a main face of at least one of the first and second sheets of glass, and the joining of the or each glass sheet provided with its sealing bead with a side wall of the spacer frame.
- the subject of the invention is a method of manufacturing a multiple glazing unit comprising at least one spacer frame fixed between a first and a second sheet of glass, each of the first and second sheets of glass being connected to a side wall of the spacer frame via a sealing bead, the method comprising steps in which:
- a sealing bead is deposited on a peripheral portion of a main face of the first glass sheet, which is intended to be bonded to a first side wall of the spacer frame;
