Definitions

  • the object of the invention is a method for attaching a glass element to a frame.
  • the object of the invention is also glazing.
  • Doors and windows typically comprise glazing, which comprises a frame, to which a plate glass, or other glass element, is attached.
  • a glass element is attached to a frame with a glazing bead, which is attached to the frame, for example by nailing, so that the glass element is between the glazing bead and the glazing rabbet of the frame.
  • a problem with this solution is that attachment of glazing beads requires numerous working phases, which are difficult to automate. It is possible to attach a glass element to a frame also with silicone, wherein the problem is a long curing time of silicone, during which time the frame and the glass element cannot be transferred, for example by lifting from the glass element.
  • the object of the present invention is to provide an improved method and glazing with which the above described problems can be reduced.
  • a method according to claim 1 for attaching a glass element to a frame provided with a glass opening In the method according to the invention the glass element is fitted against a glazing rabbet on the edge of the glass opening, and the glass element is attached to the frame. Before actual attachment the glass element is preattached to the frame so that hot melt adhesive is arranged on the surface of the glazing rabbet, and the glass element is fitted against the glazing rabbet so that the hot melt adhesive is between the glass element and the frame. Hot melt adhesive is molten above a certain temperature and cures when the temperature falls. After the gluing with hot melt adhesive silicone is applied between the glass element and the frame, with which silicone the glass element is actually attached to the frame.
  • the glazing according to the invention comprises a frame with a glass opening, on the edge of which there is a glazing rabbet against of which a glass element is fitted.
  • Hot melt adhesive is arranged between the glazing rabbet and the glass element, with which hot melt adhesive the glass element is preattached to the frame.
  • Hot melt adhesive is molten above a certain temperature and cures when the temperature falls.
  • Silicone is arranged between the glass element and the frame and/or on a corner between a front surface of the glass element and an inner surface of the frame, with which silicone the glass element is attached to the frame.
  • a glass element is first preattached to a frame with hot melt adhesive, which cools and cures fast, in about 10-30 seconds.
  • Hot melt adhesive practically cools and cures as soon as the glass element is fitted against a glazing rabbet, wherein glass reaches the hot melt adhesive and cools it.
  • the glazing i.e. the frame and the glass element preattached to it, can be transferred from the glass element by lifting to the next working phase, for example to gluing phase, where the glass element is actually attached to the frame, for example with silicone.
  • the actual gluing of the glass element can take place at the same working place as the hot melt adhesive gluing takes place, wherein there is more time for hot melt adhesive to cool and cure, as the applying of the actual glue takes time.
  • the frame and the glass element can be transferred from the glass element by lifting to the next working stage and/or packed before curing of the actual adhesive, since preattachment with hot melt adhesive keeps the glass element attached to the frame. This saves time needed for preparation of a frame, because there is no need to wait for curing of the actual adhesive before the frame is transferred by lifting.
  • the method according to the invention is also easy to automate.
  • the solution according to the invention can be used in connection with several types of glazings provided with a frame.
  • a recess or recesses such as a groove
  • a glazing rabbet of the frame into which recess hot melt adhesive is applied so that hot melt adhesive areas are at a distance from each other.
  • a glass element is fitted on the recess/recesses, wherein the additional hot melt adhesive flows into the recess.
  • the depth and/or width of the recess can be formed so that hot melt adhesive cures in the recess as fast as desired.
  • the thermal conductivity of the material of the frame has effect on the curing rate of the hot melt adhesive. If the thermal conductivity of the frame is high, the recess can be made to be deeper than normally, wherein the hot melt adhesive in the recess cures slower.
  • Figs. 1-3 present glazings 1 comprising a frame 2 with a glass opening 3, into which a glass element 4 is fitted.
  • the glass element 4 is attached to the frame 2.
  • the glazing rabbet 5 extends towards the inner part of the opening 3 edged by the frame 2.
  • the glass element 4 is so called 2K-glass element comprising two plate glasses 6 having a gas tight space 7 between them. There is gas, such as argon, in the space 7 improving thermal resistance of the glass element 4.
  • the glasses 6 are separated from each other with a parting strip 8.
  • the glass element 4 can comprise three or more glasses 6, which are arranged one after the other, between which there are gas tight spaces 7 and which are separated from each other with parting strips 8.
  • the glass element 4 is a single plate glass 6.
  • the glazings 1 of figs. 1 and 2 can be a part of the window.
  • the glazing of fig. 1 can be an inner frame of the window, and the glazing of fig. 2 an outer frame of the same window.
  • the frame 2 comprises also an upper part and two side parts into which the glass element 4 is attached.
  • the glazing 1 can be a door, into frame of which the glass element is attached.
  • the frame comprises a glass opening having a glazing rabbet 5 on the edge of it, against of which glazing rabbet 5 the glass element is fitted.
  • the frame 2 comprises one or more recesses 9 in a place where the glass element 4 is fitted against the frame 2, such as in the glazing rabbet 5.
  • the recess 9 is a longitudinal groove extending longitudinally to the part forming the frame.
  • the groove can be in all the parts of the frame (in lower part, in upper part and in side parts) or only in some of the parts of the frame (e.g. in lower and upper parts). Dimensions of the groove, such as depth and/or width, are selected to be suitable for the embodiment, inter alia, according to the thermal conductivity of the material of the frame.
  • Hot melt adhesive in the recess or recesses 9 with which hot melt adhesive the glass element 4 is preattached to the frame 2.
  • Hot melt adhesive is molten above a certain temperature and it cures when the temperature falls.
  • Hot melt adhesive is arranged dropwise in the recess 9 so that the areas comprising hot melt adhesive are at a distance from each other.
  • the distance between the adjacent hot melt adhesive areas or hot melt adhesive drops in the recess 9 is at least 20 cm, typically 30-40 cm.
  • the distance between the adjacent hot melt adhesive areas depends, inter alia, on the mass of the frame 2 and on the characteristics of the hot melt adhesive. It is important that there is an area between the adjacent hot melt adhesive areas in the recess 9 without hot melt adhesive. Then the additional hot melt adhesive flows into the recess 9 and does not get squeezed between the glass element 4 and the surface of the frame 2.
  • the glass element 4 is attached to the frame 2 with adhesive suitable for the purpose, such as silicone, advantageously sg silicone (structural glazing silicone).
  • Adhesive is arranged between the glass element 4 and the frame 2, e.g. in the area of the inner surface 10 of the frame. Additionally, silicone is arranged on the corner between the front surface 11 of the glass element 4 and the inner surface 10 of the frame.
  • the inner surface 10 of the frame borders the glass opening 3. The inner surface 10 is perpendicular to the front surface 11 of the glass element.
  • Glazing 1 according to figures 1 and 2 is produced as follows.
  • the glazing rabbet 5 of the frame is provided with a recess 9 or recesses, such as a groove, which extends in the longitudinal direction to the part forming the frame 2.
  • Dimensions of the recesses 9, such as width and/or depth, are selected so that hot melt adhesive in the recess 9 cools and cures as fast as desired.
  • the width and/or the depth of the recess 9 is selected also on the basis of the thermal conductivity of the material.
  • the frame 2 is set on a base, e.g. on a horizontal base. Silicone mass is applied on the surface of the glazing rabbet 5 of the frame 2, with which silicone mass the space between the glass element 4 and the frame 2 is sealed. Hot melt adhesive is applied on the surface of the glazing rabbet 5, with which hot melt adhesive the glass element 4 is preattached to the frame 2. In the embodiment according to the drawings this takes place so that hot melt adhesive is arranged on the recess 9 or recesses 9 of the glazing rabbet 5 before the glass element 4 is set in its place against the glazing rabbet 5. Hot melt adhesive is applied over the whole height of the recess 9 so that the hot melt adhesive layer extends at least on the level of the edges of the recess.
  • Hot melt adhesive is applied dropwise on the recess 9 so that hot melt adhesive drops are at a distance from each other.
  • the distance between adjacent hot melt adhesive drops depends on the mass of the frame 2. The greater the mass of the frame 2, the smaller is the distance between the hot melt adhesive drops.
  • the distance between adjacent hot melt adhesive areas or hot melt adhesive drops is at least 20 cm, typically 30-40 cm.
  • Hot melt adhesive is brought into recess 9, e.g. by a glue gun.
  • Adhesive is heated in the glue gun, where it melts.
  • the molten adhesive is led from the nozzle of the glue gun into a desired place in the recess 9.
  • the glass element 4 After the appliance of hot melt adhesive the glass element 4 is set against the glazing rabbet 5. The glass element 4 is set against hot melt adhesive in the recess 9, wherein the additional hot melt adhesive flows into the recess 9 and does not get squeezed between the glass element 4 and the surface of the frame 2 next to the recess 9.
  • Hot melt adhesive cools and cures in the recess 9 and preattaches the glass element 4 to the frame 2.
  • the depth of the recess determines the cooling and curing rate of hot melt adhesive. The deeper the recess 9, the slower hot melt adhesive cools and cures.
  • the glass element 4 is preattached to the frame 2.
  • the glazing 1, i.e. the frame 2 and the glass element 4 attached to it, are transferred to the next handling place or handling phase, e.g. by lifting. This takes place so that suction pads or other lifting elements are attached to the glass element 4, with which suction pads or other lifting elements the glass element 4 and the frame 2 are lifted and transferred to the desired place.
  • adhesive e.g. silicone
  • silicone structural glazing silicone
  • Silicone is applied also on the corner between the glass element 4 and the inner surface 10 of the frame 2. Silicone gluing cures and reaches its gluing strength typically within a few hours.
  • the glazing 1 is transferred to the next handling place or handling phase, in which the glazing is e.g. manufactured to the desired finished product (e.g.
  • the glazing 1 is transferred from the glass element 4 by lifting to the next handling place or handling phase. This takes place so that suction cups or other lifting elements are attached to the glass element 4, with which suction cups or other lifting elements the glass element 4 and the frame 2 are lifted and transferred to the desired place.
