Description

  The present invention relates to a method for assembling a multilayer glass with a glazing channel.

  From the viewpoint of energy saving and soundproofing, multi-layer glass is often used as window glass. As a method for attaching such a double-glazed glass to a window frame (shoji, 框), a glazing channel is attached to the edge of the double-glazed glass, and the double-glazed glass is attached to the groove of the window frame via this glazing channel. A technique is disclosed in Patent Document 1.

  The glazing channel of Patent Document 1 is a metal or resin-made reinforcing material having a concave cross section surrounding the edge of the multilayer glass, and a resin made on the inner surface of the reinforcing material facing the multilayer glass. And a resin-made external soft material provided on the outer surface facing the window frame of the reinforcing material.

  Recently, a window glass has been proposed in which the window area is narrowed to widen the daylighting area of the multi-layer glass, thereby improving the heat insulation, landscape, and appearance. Here, the narrowing of the window frame means that the groove of the window frame into which the edge of the multi-layer glass with a glazing channel is inserted becomes shallow, and this is accompanied by the edge of the multi-layer glass. The depth of the groove of the glazing channel into which the portion is fitted is also reduced.

  For this reason, in the glazing channel having a general shape disclosed in Patent Document 1, the pulling load of the double glazing on the glazing channel is reduced, so that the glazing channel and the double glazing are easily separated, and assembly workability is improved. There was a problem of getting worse. In addition, a force that deforms the vertical frame on the arc by the force when opening and closing the window frame acts, and this deformation force may cause the multi-layer glass to come off from the glazing channel and consequently not return to its original shape while being curved. there were.

  Therefore, Patent Documents 2 and 3 disclose multi-layer glass with a glazing channel that solves the above problem. That is, the double-glazed glass 100 with a glazing channel disclosed in Patent Documents 2 and 3 shown in FIG. 5 includes a protrusion 104 having an arrow-shaped tip on the bottom inner surface of the glazing channel 102. The protrusion 104 is pushed into the secondary sealing material 108 of the multilayer glass 106 to be immersed therein, and when the secondary sealing material 108 is solidified, the glazing channel 102 is projected to the secondary sealing material 108 of the multilayer glass 106. 104. As a result, the pulling load of the multilayer glass 106 on the glazing channel 102 becomes high, and the glazing channel 102 and the multilayer glass 106 are difficult to separate, so that the assembly workability is improved. The two glass plates 110 and 110 constituting the multi-layer glass 106 are separated by a spacer 112, and the spacer 112 and the glass plates 110 and 110 are separated by a primary sealing material 114 and 114 having a high moisture resistance. Further, since the space portion defined by the spacer 112 and the peripheral portions of the two glass plates 110 and 110 is sealed by the secondary sealant 108, the two sheets constituting the multilayer glass 106 Since the rigidity for restraining and holding the glass plates 110 and 110 increases, deformation distortion of the primary sealant 114 around the double-glazed glass 106 caused by expansion and contraction of the air layer of the double-glazed glass 106 is suppressed.

JP-A-7-71170 JP-A-8-199920 Japanese Patent Laid-Open No. 10-299351

  By the way, in the glazing channel 102 of Patent Documents 2 and 3, since the protrusion 104 is immersed in the secondary sealing material 108 of the multilayer glass 106, external force due to wind pressure and vibration from the multilayer glass 106 is projected. It always acts on the secondary sealant 108 via the portion 104. In addition, a force for deforming the vertical frame on the arc is applied by the force when opening and closing the window frame, and the load is intermittently applied to the secondary sealant 108 via the protrusion 104 of the glazing channel 102 due to the deformation force. Act on. For this reason, since the secondary sealing material 108 deteriorates and the rigidity for restraining and holding the two glass plates 110 and 110 decreases, the primary sealing material 114 is deformed and strained, resulting in a decrease in moisture permeability resistance. There is a concern that the airtightness and watertightness are lowered, and the life of the multilayer glass 106 is shortened.

  Further, the glazing channel 102 of Patent Documents 2 and 3 is manufactured assuming a multilayer glass 106 made of two glass plates 110 and 110 having the same thickness, and the center in the width direction of the secondary sealant 108. The protruding portion 104 is provided at the center in the width direction of the glazing channel 102 so that the protruding portion 104 is immersed in the portion. For this reason, as shown in FIG. 6, the multi-layer glass 118 made of two glass plates 110 and 116 having different thicknesses is not versatile because the position of the protrusion 104A must be changed from the center to one side.

  Furthermore, in this multilayer glass 120 with a glazing channel, since the protrusion 104A is immersed in the secondary seal material 108A having a reduced size in the width direction, the holding force of the secondary seal material 108A on the protrusion 104A is reduced. A sufficient pull-out load cannot be obtained. The glass plate 116 shown in FIG. 6 is a laminated glass in which a glass plate 122 and a netted glass plate 124 are bonded via an intermediate sheet 126.

  Furthermore, in the double-glazed glass 100, 120 with glazing channel shown in FIGS. 5 and 6, when the protrusions 104, 104A are immersed in the secondary sealants 108, 108A, the tip arrows of the protrusions 104, 104A In some cases, the secondary sealing materials 108 and 108A do not wrap around the back side of the part, and even in this case, a sufficient pull-out load cannot be obtained.

  The present invention has been made in view of such circumstances, and without damaging the life of the multilayer glass, the glazing channel and the multilayer glass are firmly engaged with each other, An object of the present invention is to provide a method for assembling a double-glazed glass with a glazing channel capable of increasing the pull-out load.

In order to achieve the above object, the present invention, two glass plates separated by a spacer are overlapped via an air layer, and the two glass plates are bonded by a sealing material at an edge thereof, A step of preparing a multi-layer glass in which an outer surface of the sealing material is located inside the two glass plates from an end surface of the two glass plates; and a groove in which an edge of the multi-layer glass is fitted. And a step of preparing a glazing channel provided with a stopper piece on the side wall of the groove and having an opening at a position facing the outer surface of the sealing material, and engaging the stopper piece when solidified Applying an adhesive material to the corner of the groove of the glazing channel, fitting an edge of a multilayer glass into the groove of the glazing channel, and attaching the adhesive material to the two glass plates. Adhere to the edge Provides a method of assembling the glazing channeled double glazing, characterized in that it comprises a step.

  According to the present invention, first, an adhesive is applied to the corner of the groove of the glazing channel. Next, the edge of the multilayer glass is fitted into the groove of the glazing channel to assemble the multilayer glass with the glazing channel. According to the multilayer glass with a glazing channel assembled in this way, the solidified adhesive is bonded to the edge of the two glass plates and is engaged with the stopper piece of the glazing channel. The bond between the glazing channel and the double glazing is strengthened, and thus the pulling load of the double glazing on the glazing channel is increased.

  Further, in the assembling method of the present invention, the protrusions as in Patent Documents 2 and 3 are not used, but by the engaging force between the stopper piece disposed between the multilayer glass and the glazing channel and the solidified adhesive. Since both the bonds are strengthened, the life of the double-glazed glass is not adversely affected. Moreover, the problem of versatility can be solved.

  By the way, in the double-glazed glass with a glazing channel, moisture such as rainwater enters from a gap between the double-glazed glass and the glazing channel. This moisture is between the bottom inner bottom surface of the glazing channel and the end face of the double-glazed glass. If it stays in the substrate, there is a problem that the sealing material (secondary sealing material) of the double-glazed glass deteriorates due to the moisture.

  Therefore, the double-glazed glass with a glazing channel assembled by the assembling method of the present invention includes the double-glazed glass in which the outer surface of the sealing material is located inside the two glass plates from the end surfaces of the two glass plates, and the seal And a glazing channel provided with an opening at a position facing the outer surface of the material. Therefore, moisture that has entered from the gap between the glass layer and the glazing channel does not stay between the bottom inner surface of the glazing channel and the end surface of the glass layer, and drains from the opening of the glazing channel to the outside. Is done. Thereby, the problem of deterioration of the sealing material of the double-glazed glass can be solved, and this also does not adversely affect the life of the double-glazed glass.

  Further, it is preferable that the length of the stopper piece of the glazing channel is long so as to contact the glass plate. Thereby, the airtightness of the clearance gap between a glazing channel and a multilayer glass, and watertightness improve. Note that the inner soft member provided in advance in the glazing channel may also be used as the stopper piece.

  The glazing channel of the present invention is preferably made of a resin, and the adhesive is preferably an adhesive having a higher adhesive force to the glass plate than an adhesive force to the glazing channel.

  When the glazing channel is damaged, for example, when handling the multi-glazing with a glazing channel, it is necessary to remove the glazing channel from the multi-glazing and replace it with a new glazing channel. At this time, in the multilayer glass with a glazing channel of Patent Documents 2 and 3, since the protrusion is fixed to the secondary sealing material, the glazing channel cannot be easily detached from the multilayer glass. Also, if you try to remove it by applying excessive force, the secondary seal material will be damaged by the projection, and even if you try to install a new glazing channel, insert the projection again into the already cured secondary seal material, There was a problem that a predetermined bonding force could not be obtained.

  On the other hand, since the present invention uses an adhesive having a higher adhesion to the glass plate than the adhesion to the glazing channel, the glazing channel can be easily detached from the multilayer glass and adhered to the multilayer glass. The sealing material can be scraped off with a cutter or the like.

  The adhesive of the present invention is preferably an adhesive based on a curable elastomer such as silicone, polysulfide, or urethane.

Such an adhesive has high adhesion to the glass plate and low adhesion to the resin. Therefore, the glazing channel can be easily removed from the multilayer glass.
The adhesive of the present invention is preferably adhered to the end surface of the multilayer glass when solidified.

  According to the method for assembling a multi-layer glass with a glazing channel of the present invention, the multi-layer glass is drawn out of the glazing channel by firmly bonding the glazing channel and the multi-layer glass without adversely affecting the life of the multi-layer glass. The load can be increased.

  Hereinafter, preferred embodiments of a method for assembling a multilayer glass with a glazing channel according to the present invention will be described in detail with reference to the accompanying drawings. In addition, this invention is limited to the following description and is not interpreted.

  FIG. 1 is a cross-sectional view showing a first embodiment of a multilayer glass 10 with a glazing channel assembled by the assembling method of the present invention.

  In the figure, a part of the multi-layer glass 10 with glazing channels is shown in cross section, but this multi-layer glass 10 with glazing channels is used as a glass plate for windows, and the overall shape is rectangular. It is a glass panel. Moreover, in order to improve the heat insulating property, the landscape property, and the appearance, the multi-layer glass 10 with a glazing channel is attached to a wall surface of a building by fitting an edge portion thereof into a thin window frame (not shown). Further, the double-glazed glass with a glazing channel 10 is configured by attaching glazing channels 14 to the end edges of four sides of a rectangular double-glazed glass 12. That is, the glazing channel 14 is attached to all edge portions of the multilayer glass 12.

  The multilayer glass 12 has two glass plates 16, 16 spaced apart via a spacer 18, whereby an air layer 20 is formed between the glass plates 16 and 16, and both sides of the spacer 18 are formed. The surface is bonded to the glass plates 16 and 16 by the primary sealing materials 22 and 22. Further, the edge of the multilayer glass 12 is sealed with a secondary sealing material (sealing material) 24.

  The spacer 18 is a hollow metal mold, and a moisture absorbing material 26 such as silica gel is accommodated therein. Further, a through hole 28 is opened on the surface of the spacer 18 on the air layer 20 side, and air in the air layer 20 is dried by the hygroscopic material 26 through the through hole 28.

  As the primary sealing material 22, an adhesive and low moisture-permeable resin material is used, and in particular, butyl rubber is used. Moreover, as the secondary sealing material 24, a polysulfide sealant or a silicone sealant having high adhesion to glass is used. Further, the secondary sealing material 24 has an outer surface 24A on the inner side of the two glass plates 16, 16 from the end surfaces 16A, 16A of the two glass plates 16, 16 (on the air layer 20 side of the multilayer glass 12). It is applied so that it is located. Thereby, in the double-glazed glass 10 with a glazing channel, a gap is formed between the outer surface 24A of the secondary sealing material 24 and the bottom inner bottom surface of the glazing channel 14, and the moisture that has entered this space becomes the secondary sealing material 24. Long-term contact is avoided. From this point of view, the gap d between the end face 16A and the outer surface 24A is preferably set so that d + t is 3 mm or more, where t is the thickness of the bottom of the reinforcing member 30 described later. For example, when t = 0.5 mm, d is preferably 2.5 mm or more.

  In FIG. 1, the outer surface 24 </ b> A of the secondary sealing material 24 is an arcuate surface, but the shape is not limited to this and may be a horizontal surface. That is, the effect of moisture contact on the outer surface 24A is reduced, such as by making the gap between the outer surface 24A and the bottom inner bottom surface of the glazing channel 14 into a substantially rectangular cross-sectional shape. Various shapes can be adopted as long as they are not impaired. In FIG. 1, two glass plates having the same thickness are illustrated as the glass plates 16 and 16 of the multilayer glass 12, but the present invention is not limited to this. For example, one glass plate 16 is replaced with the other glass plate 16. The glass may be thicker than the glass plate 16. Further, as the glass plate 16, various glass plates such as a mold plate glass, a meshed glass, a polished plate glass, a heat-resistant tempered glass, and a glass with a functional coating may be used in addition to a normal float plate glass. Similarly, as the glass plate 16, in addition to single plate glass, laminated glass in which a plurality of glass plates are laminated via an intermediate adhesive layer can be used.

  On the other hand, the glazing channel 14 includes a reinforcing material 30, an internal soft material 32, and an external soft material 34, and the edge portion of the multilayer glass 12 is formed by the reinforcing material 30, the internal soft material 32, and the external soft material 34. A groove is formed to cover.

  The reinforcing material 30 is made of a resin such as a hard vinyl chloride resin material, and is configured to have a concave cross section so as to surround the edge of the multilayer glass 12. The internal soft material 32 is made of a resin such as a soft vinyl chloride resin material, and is provided on the inner wall surface of the reinforcing material 30 at the periphery of the multilayer glass 12 so as to be opposed to the glass plates 16 and 16. Similarly, the external soft material 34 is made of a resin such as a soft vinyl chloride resin material, and is provided at the upper end of the reinforcing material 30. The external soft material 34 has a locking portion to the tip of the mounting opening of the window frame and is in close contact with the glass plates 16 and 16, thereby improving the air tightness and water tightness of the edge portion of the multilayer glass 12. Hold. The reinforcing material 30, the internal soft material 32, and the external soft material 34 are integrally formed using an appropriate forming means such as an extrusion forming means. In addition, a drain opening 36 is provided at the bottom of the reinforcing member 30, that is, at a position facing the outer surface 24 </ b> A of the secondary sealing member 24. The openings 36 are provided at predetermined intervals along the longitudinal direction of the glazing channel 14.

  The glazing channel 14 also uses the internal soft material 32 as a stopper piece to be described later, but a dedicated stopper piece may be provided separately from the internal soft material 32. In this case, the stopper piece is not limited to the soft member and may be a hard member.

  An adhesive 38 applied to the inner corner portion 14A of the groove of the glazing channel 14 is solidified and engaged with the internal soft material 32 that is also used as a stopper piece. The engagement direction of the internal soft material 32 with respect to the adhesive material 38 is a direction in which resistance is applied in a direction in which the multilayer glass 12 is pulled out of the glazing channel 14. That is, the adhesive 38 </ b> A interposed between the surface of the multilayer glass 12 and the inner wall surface of the glazing channel 14 of the adhesive 38 is solidified and engaged with the internal soft material 32. Of the adhesive 38, the adhesive 38 </ b> B interposed between the end surface 16 </ b> A of the glass plate 16 and the bottom surface of the glazing channel 14 is bonded to the end surface 16 </ b> A of the glass plate 16.

  As the adhesive 38, an adhesive having a higher adhesive strength to the glass plate 16 than an adhesive strength to the resin glazing channel 14 is used, and an adhesive based on a curable elastomer such as silicone, polysulfide, or urethane is used. ing.

  Next, a method for assembling the multi-layer glass 10 with the glazing channel configured as described above will be described.

  First, as shown in FIG. 2, the adhesive 38 is applied to the inner corner 14 </ b> A of the groove of the glazing channel 14 from the nozzle 42 of the coating device 40. The application amount of the adhesive 38 depends on the size of the glazing channel 14, but the application device 40 is applied along the inner corner 14 </ b> A at an application amount of 0.45 to 1.2 g per 10 cm in the longitudinal direction of the glazing channel 14 on one side. The adhesive 38 is applied to the entire inner corner 14A while moving. Further, the application position of the adhesive material 38 is applied so as to wrap around the lower side of the internal soft material 32 functioning as a stopper piece. As a result, when the internal soft material 32 is pressed into contact with the multi-layer glass 12 and elastically deforms downward, the entire lower surface of the internal soft material 32 contacts the adhesive material 38. The engagement force with is increased.

  When the application of the adhesive 38 is completed, the edge of the multilayer glass 12 is then fitted into the groove of the glazing channel 14. Thereby, the multilayer glass 10 with a glazing channel shown in FIG. 1 is assembled.

  According to the multilayer glass 10 with a glazing channel assembled in this way, the adhesive 38 (38A) firmly adhered and solidified to the multilayer glass 12 side is engaged with the internal soft material 32 of the glazing channel 14. Therefore, the bond between the glazing channel 14 and the multilayer glass 12 becomes strong. Therefore, the pulling-out load of the multilayer glass 12 with respect to the glazing channel 14 becomes high.

  Moreover, in this multilayer glass 10 with a glazing channel, without using the projection parts 104 and 104A (refer FIG. 5, FIG. 6) like patent document 2, 3, between the multilayer glass 12 and the glazing channel 14 is used. Since the coupling between both the inner soft material 32 and the solidified adhesive 38 (38A) is strengthened by the engaging force, the life of the multilayer glass 12 is not adversely affected. Moreover, the problem of versatility can be solved.

  In this example, the adhesive material 38 is applied to the entire area of the inner corner portion 14A over the longitudinal direction of the glazing channel 14, but it is applied only to a region excluding the corner portion of the multilayer glass 12, or at a predetermined interval. Various design changes can be made without departing from the gist of the present invention, such as intermittent application.

  By the way, in the multi-layer glass 10 with the glazing channel assembled in this way, the outer surface 24A of the secondary sealing material 24 is formed from the end surfaces 16A, 16A of the two glass plates 16, 16 to the two glass plates 16, 16. It is constituted by the double-glazed glass 12 located on the inner side (the air layer 20 side of the double-glazed glass 12) and the glazing channel 14 provided with the opening 36 at a position facing the outer surface 24A of the secondary sealing material 24. Yes. Therefore, moisture that has entered from the gap between the multilayer glass 12 and the glazing channel 14 does not stay between the bottom inner bottom surface of the glazing channel 14 and the end surface of the multilayer glass 12, and the opening of the glazing channel 14. The water is discharged from the portion 36 to the outside.

  Thereby, since the problem that the secondary sealing material 24 of the multilayer glass is deteriorated due to retention of moisture can be solved, the life of the multilayer glass 12 is not adversely affected in this respect as well.

  By the way, the multilayer glass 10 with a glazing channel may be conveyed while the multilayer glass 10 with a glazing channel is erected on-site at the time of transportation and rotated in the plane direction. During this transport, if the glazing channel 14 is damaged, the glazing channel 14 must be removed from the double glazing 12 and replaced with a new glazing channel 14.

  At this time, in the multi-layer glass with a glazing channel 100 and 120 shown in FIGS. 5 and 6, since the protrusions 104 and 104A are fixed to the secondary sealing materials 108 and 108A, the glazing channel 102 is formed into the multi-layer glass. 106 and 118 cannot be easily removed. In addition, if an excessive force is applied to remove the secondary sealant 108, 108A, the protrusions 104, 104A break the secondary sealant 108, 108A.

  On the other hand, the multilayer glass 10 with a glazing channel of the embodiment shown in FIG. 1 uses an adhesive 38 having a higher adhesive force to the glass plate 16 than that to the glazing channel 14. The glazing channel 14 can be easily removed from the layer glass 12.

  FIG. 3 is a cross-sectional view showing a second embodiment of the glazed channel-attached multi-layer glass 50 assembled by the assembling method of the present invention, and FIG. 4 shows a glazing-channel multi-layer glass 60 assembled by the assembling method of the present invention. It is sectional drawing which shows the 3rd form. In the description of the double glazing channels 50 and 60 with glazing channels, the same or similar members as those in the glazing channel double glass 10 shown in FIGS. To do.

  In the double-glazed glass 50 with a glazing channel shown in FIG. 3, an adhesive 38 is interposed only between the surface of the double-glazed glass 12 and the inner wall surface of the glazing channel 14.

  The multi-layer glass 60 with the glazing channel shown in FIG. 4 does not include the inner soft material 32 in the glazing channel 14, and the protruding stopper piece 62 integrally formed with the reinforcing material 30 is an adhesive 38 having a substantially rectangular cross section. Is engaged. The stopper piece 62 is not in contact with the multilayer glass 12, and in this case, the adhesive 38 functions as a sealing material. Further, the stopper piece 62 is made of a resin such as a hard vinyl chloride resin material, and the pulling load becomes higher than that in which the soft inner soft material 32 is engaged with the adhesive material 38.

  As shown in FIGS. 1, 3, and 4, the shape of the adhesive material 38 is not particularly limited as long as it can be engaged with the internal soft material 32 and the stopper piece 62. Moreover, it is preferable that the coating amount of the adhesive 38 is not more than half of the height of the glazing channel 14 from the inner corner portion 14 </ b> A of the glazing channel 14 in the assembled multilayer glass 10, 50, 60 with glazing channel. If the adhesive material 38 is applied in an amount larger than that, the adhesive material 38 protrudes outside the glazing channel 14 when the glazing channel 14 is attached to the multi-layer glass 12, and the appearance may be impaired. This is because the material 38 becomes a resistor and it becomes difficult to fit the multi-glazed glass 10, 50, 60 with glazing channel into the window frame.

  In the embodiment, after the adhesive 38 is applied to the glazing channel 14, the multilayer glass 12 is fitted to the glazing channel 14. However, after the multilayer glass 12 is fitted to the glazing channel 14, bonding is performed. The adhesive 38 may be applied by inserting a small-diameter nozzle into the gap between the multilayer glass 12 where the material 38 is located and the glazing channel 14.
