Description

  The present invention relates to a structure for attaching a glass panel to a sash through a glazing channel disposed on the peripheral edge of a glass panel such as double-glazed glass or laminated glass.

  A glazing channel (attachment, bead material) is attached to the periphery of the multilayer glass to attach the multilayer glass to the sash of the building. The glazing channel has a substantially U-shaped cross section, and a drainage hole for draining water is provided on the bottom surface of the glazing channel attached to the lower side of the multilayer glass (see, for example, Patent Document 1). An inner soft part is formed on the inner side surface of the hard reinforcing material forming the attachment (glazing channel) described in Patent Document 1, so that the multilayer glass does not come into contact with the reinforcing material of the attachment, and the reinforcing material and A space is provided between the multilayer glasses to prevent the end face of the multilayer glass from being exposed to moisture for a long time when moisture enters, and the sealing material from being deteriorated.

  However, it is not clear how large the gap of the attachment of Patent Document 1 is provided by the inner soft part and the above effect is exhibited. Usually, the height of the inner soft part is around 0.4 mm, and a sufficient gap is not formed. Therefore, before the moisture that has entered between the end surface of the multilayer glass and the attachment is discharged to the outside of the attachment, the multilayer glass There is a risk that the multi-layer glass end face will be exposed to moisture for a long time. The drain holes are scattered in the longitudinal direction on the bottom surface of the attachment, and are usually formed with a pitch of about 50 mm and a diameter of about 8 mm. Therefore, moisture may remain between the drain holes, and this moisture may deteriorate the sealing material provided at the peripheral edge of the multilayer glass. In addition, even when such an attachment is attached to the peripheral edge of the laminated glass, moisture that has entered between the laminated glass and the attachment is difficult to be discharged, so that the interlayer film is exposed to moisture at the peripheral edge of the laminated glass for a long time. May cause peeling.

  The present invention is based on the above prior art, forms a sufficient gap between the end surface of the glass panel to which the glazing channel is attached and the bottom surface of the glazing channel, and eliminates the retention of moisture in the glazing channel. An object of the present invention is to provide a glass panel sash mounting structure that prevents the end face of the glass panel from being exposed to moisture, and further improves drainage at the corner of the glass panel having a glazing channel attached to the peripheral edge.

  In order to achieve the above object, the invention of claim 1 is a glass panel sash mounting structure formed by stacking a plurality of glass plates, the glass panel both surfaces and the glass along the periphery of the glass panel. A glazing channel is attached to the sash via a glazing channel attached to the glass panel so as to cover the panel end surface, and the glazing channel attached to the lower side of the glass panel is a bottom portion covering the glass panel end surface, and a peripheral portion of the glass panel And a side surface portion that covers both sides of the glass panel, a gap of 3 to 10 mm in height is provided between the glass panel end surface and the bottom end surface of the bottom surface portion, and the gap communicates with the outside of the glazing channel. An opening is provided in the glazing channel, and the glass panel sash is removed. To provide a structure.

  In the invention of claim 2, the bottom portion is divided along the longitudinal direction of the glazing channel in the vicinity of the center portion in the width direction, and the divided bottom portions are connected by one or a plurality of connecting pieces, The opening is provided at least near both ends in the longitudinal direction of the glazing channel.

  According to a third aspect of the present invention, the glass panel is a multi-layer glass in which a plurality of glass plates are stacked via an air layer, and the gap is a width greater than or equal to a width of a sealing material provided at a peripheral edge of the multi-layer glass. And is provided at a position corresponding to the sealing material.

  In the invention of claim 4, the glass panel is a laminated glass in which a plurality of glass plates are laminated via an adhesive layer, and the gap has a width equal to or larger than the width of the adhesive layer of the laminated glass, and It is characterized by being provided at a position corresponding to the adhesive layer.

  In the invention of claim 5, at both ends in the longitudinal direction of the glazing channel attached to the lower side of the glass panel, the glazing channel and another glazing channel arranged on the vertical side of the glass panel are joined by the joining member. It is characterized by that.

  According to the first aspect of the present invention, since the gap of 3 to 10 mm is provided between the lower end surface of the bottom surface portion of the glazing channel and the end surface of the glass panel at the lower side of the glass panel, the bottom surface portion of the glazing channel and the glass A sufficient gap is formed between the ridged surface of the panel, so that moisture that has entered between the glazed channel and the glazing channel adheres to the edge of the glass panel due to surface tension before it is discharged outside the glazing channel. And will not stay. In addition, since the opening communicates with the gap and the outside of the glazing channel, moisture that has entered the glazing channel is quickly discharged to the outside of the glazing channel, so that the end face of the glass panel can be prevented from being exposed to moisture for a long time. .

  According to invention of Claim 2, when attaching a glazing channel to the lower side of a glass panel, it opens to a bottom face part by dividing the bottom face part of a glazing channel along the longitudinal direction of a glazing channel near the center part of the width direction. Since the divided bottom surfaces are connected by one or a plurality of connecting pieces, moisture that has entered the glazing channel can be easily removed from the outside while maintaining workability when attaching to the glass panel. Can be discharged. In addition, since the bottom surface portion that is divided so that both ends of the bottom surface portion are open is connected by a connecting piece (substantially ladder-like), the number of parts does not increase even though the glazing channel is divided. In addition, since the openings are provided in the vicinity of at least both ends in the longitudinal direction of the glazing channel, it is easy to discharge moisture that has entered the glazing channel at the corner of the glass panel. In this way, by opening the glazing channel at the corner of the lower side of the glass panel and draining from there, the glazing channel is attached to the lower side with rainwater entering the glazing channel arranged on the left and right vertical sides of the glass panel. The occurrence of problems such as deterioration of the sealing material due to moisture is suppressed.

  According to the invention of claim 3, the gap provided between the end face of the glass panel and the bottom part of the glazing channel is set so as to have a width equal to or greater than the width of the sealing material provided in the peripheral part of the multilayer glass, In addition, since this gap is provided at a position corresponding to the seal material, the double-glazed seal material does not directly contact the glazing channel. Therefore, moisture that has entered the glazing channel does not contact the sealing material for a long time, and deterioration of the sealing material due to moisture is prevented. Further, in the case of a double glazing having two or more air layers, one or a plurality of gaps may be provided so as to correspond to the sealing materials provided at the peripheral portions of the plurality of air layers. In addition, as the multi-layer glass used in the present invention, a pair of glass plates are overlapped via an aluminum spacer, the spacer and the glass plate are bonded and sealed with a primary seal, and the outer edge portion of the spacer is sealed. Either of the two glass plates sealed with a secondary seal, or a molded product made of a synthetic resin material may be used as a spacer, and the spacer and the glass plate may be bonded and sealed with a sealing material. In the case of double-glazed glass using a secondary seal, the width of the gap may be set so as to have a width greater than that of the secondary seal, and a secondary seal using a spacer made of a synthetic resin material is not used. In the case of double-glazed glass, the width of the gap may be set so as to have a width equal to or greater than the width of the synthetic resin spacer.

  According to the invention of claim 4, the gap provided between the glass panel end face and the bottom surface portion of the glazing channel has a width equal to or larger than the width of the adhesive layer provided between the plurality of glass plates constituting the laminated glass. Since the gap is provided at a position corresponding to the adhesive layer, the adhesive layer of the laminated glass does not directly contact the glazing channel. Therefore, the moisture that has entered the glazing channel does not come into contact with the adhesive layer for a long time, and peeling and deterioration of the adhesive layer due to moisture are prevented. In order to apply the present invention when any one of a plurality of glass plates constituting the multilayer glass is laminated glass, it corresponds to the position corresponding to the sealing material of the multilayer glass and the adhesive layer of the laminated glass. A gap may be provided at each position.

  According to invention of Claim 5, it can join firmly with the other glazing channel distribute | arranged to the vertical side of a glass panel in the both ends of the lower side of a glass panel.

  FIG. 1 is a cross-sectional view of a multi-layer glass having a glazing channel according to the present invention attached to a sash. In addition, the glazing channel according to the present invention can be applied to a glass panel such as laminated glass in addition to the multilayer glass.

In order to attach the multilayer glass 1 to the sash 2, a glazing channel (attachment, peade material) 3 is attached to the peripheral edge of the multilayer glass 1. The double glazing 1 to which the glazing channel 3 is attached is attached to the sash 2 through a setting block 19. The glazing channel 3 has a substantially U-shaped cross section, and includes a bottom surface portion 4 made of a hard resin member on which the end surface of the multi-layer glass 1 is placed, and a hard resin member that covers both surfaces of the multi-layer glass 1 with the peripheral edge portion of the multi-layer glass 1. And a side surface portion 5 constituted by an elastic upper edge portion 5b made of a soft resin member provided on an upper portion of the side surface lower piece portion 5a. The peripheral side of the multi-layer glass 1 is held by the hard side lower piece 5a, and the elastic upper edge 5b prevents rainwater and the like from entering. A soft resin member is provided on a part of the surface of the side lower piece 5a that contacts the multilayer glass 1 to prevent the hard resin member of the side lower piece 5a and the multilayer glass 1 from coming into direct contact. Alternatively, the side surface lower piece 5a may have a cross-sectional shape that widens toward the elastic upper edge 5b.

  The multilayer glass 1 is formed by interposing a spacer 9 between two glass sheets 8 and 8 via a primary seal 6 and sealing the outside with a secondary seal 10. A through hole 12 is formed on the upper surface side of the spacer 9, and a dry operation agent 11 is filled in the spacer 9. A bottom raising member 13 is provided between the end surface of the multilayer glass 1 (the end surfaces of the glass plates 8 and 8) and the bottom surface portion 4 so that the total height of the bottom raising member 13 and the bottom surface portion 4 is 3 to 10 mm. A gap 14 is formed between the secondary seal 10 of the multilayer glass 1 and the connecting piece 7. Thus, by setting the total height of the bottom raising member 13 and the bottom surface portion 4 to 3 to 10 mm, a sufficiently high gap 14 is formed below the secondary seal 10 of the double-glazed glass 1. Even if moisture such as rainwater permeates between the end surface of the multi-layer glass 1 and the glazing channel 3, the water does not stay in close contact with the end surface of the multi-layer glass 3 due to surface tension. It is discharged outside.

  Further, instead of providing the bottom raising member 13, the bottom surface portion 4 of the glazing channel 3 is formed thick so that a gap of 3 to 10 mm in height is provided between the end surface of the multi-layer glass 1 and the bottom surface portion 4. May be. In addition, it is preferable to provide a soft resin member in the surface which contacts the end surface of the multilayer glass 1, such as the raising member 13.

  The bottom surface portion 4 is divided along the longitudinal direction of the glazing channel 3 in the vicinity of the center portion in the width direction, and the divided bottom surface portions 4 are separated by one or a plurality of connecting pieces 7 provided at predetermined intervals in the longitudinal direction. Connect to each other. By dividing the bottom surface portion 4 in this way, an opening 15 is formed (see FIG. 2). Since the glazing channel 3 is not completely separated by the connecting piece 7, workability at the time of attachment to the double glazing 1 is not deteriorated. Due to the opening 15, the infiltrated moisture is surely discharged to the outside of the glazing channel 3, so that the secondary seal 10 can be prevented from being exposed to moisture for a long time. Therefore, peeling from the multilayer glass 1 due to deterioration of the secondary seal 10 is unlikely to occur.

  Usually, the distance H from the upper end surface of the sash 2 to the bottom surface of the sash 2 is set to about 16 to 20 mm. In addition, the insertion amount b of the double glazing 1 into the glazing channel 3 is to prevent the sealing material (primary seal and secondary seal) provided in the double glazing 1 from being deteriorated by ultraviolet rays. A search to the extent that it can be shielded from an external light beam is necessary, and is about 13 mm or more, preferably 14 mm or more, and more preferably about 14.6 mm. On the other hand, the distance e from the upper end surface of the sash 2 to the end surface of the double glazing 1 (insertion of the double glazing 1 into the sash 2) needs to be 6 mm or more, preferably 8 mm or more. More preferably, it is about 10 mm. Therefore, if the height d of the setting block 19 is 4 to 5 mm, the distance c between the end surface of the multilayer glass 1 and the lower end surface of the bottom surface portion 4 must be 10 mm or less. Moreover, if the distance c between the end surface of the multi-layer glass 1 and the lower end surface of the bottom surface portion 4 is less than 3 mm, the drainage performance of the water that has entered the glazing channel 3 is not ensured. Therefore, the distance c between the end surface of the multi-layer glass 1 and the lower end surface of the bottom surface portion 4 may be 3 to 10 mm (in this case, the distance e from the upper end surface of the sash 2 to the end surface of the multi-layer glass 1 is 6). ~ 13mm).

  The distance a from the upper end surface of the sash 2 to the upper end surface of the elastic upper green portion 5b greatly affects the appearance of the multi-layer glass mounted on the sash, and is preferably as small as possible. Specifically, if the distance a is 4 mm or less, the appearance is not hindered so much, which is very preferable. Similarly to the above, for the purpose of preventing the sealing material provided on the double-glazed glass 1 from being deteriorated by ultraviolet rays, the distance a may be more than 4 mm and 5 mm or less. Therefore, the distance a from the upper end surface of the sash 2 to the upper end surface of the elastic upper edge 5b is 4 to 5 mm, and the insertion amount b of the multilayer glass 1 into the glazing channel 3 is 13 mm or more. More preferably, the distance c between the end surface and the lower end surface of the bottom surface portion 4 is 3 to 7 mm (in this case, the distance e from the upper end surface of the sash 2 to the end surface of the multilayer glass 1 is 8 to 13 mm). On the contrary, if the distance c between the end surface of the multi-layer glass 1 and the lower end surface of the bottom surface portion 4 exceeds 10 mm, the distance a from the upper end surface of the sash 2 to the upper end surface of the elastic upper green portion 5b increases. Is greatly exposed from the sash 2 and is not preferable on the outer frame.
