Description

  The present invention relates to a multi-layer glass support structure and a multi-layer glass, in which a multi-layer glass is attached to a structural member to constitute a wall surface of a building.

  Conventionally, when a wall surface is made of double-glazed glass without using a sash, a holder holder is arranged on the outer peripheral edge of the double-glazed glass, and is attached to the building frame via a holder or a holder part that forms part of the building frame. The joints between the adjacent double glazings were filled with a sealing material (for example, see Patent Document 1). However, this multi-layer glass support structure is such that when the multi-layer glass is attached to the building frame, the operator must perform the work such as welding the holder and the frame on the inside (the frame side) while pressing the multi-layer glass from the outside. The work was very troublesome. In addition, after the secondary seal that closes the end of the multilayer glass is cured in order to place the holder holder, a concave portion must be formed in the secondary seal portion substantially parallel to the side of the plate glass. It was troublesome.

The workability of mounting is improved.

FIG. 1 is a cross-sectional view of a multilayer glass support structure according to the present invention, and FIG. 2 is a cross-sectional view of a support member used therefor.
As shown in the figure, the multi-layer glass 1 is formed, for example, by laminating laminated glass 13 obtained by laminating 8 mm and 5 mm single glass sheets 11 and 12 and two 3 mm single glass sheets through an intermediate film from the outside. The spacers 16 and 17 are disposed between the glass plates via the primary seal 18 to form the hollow layers 14 and 15 having a thickness of 12 mm and 18 mm. The spacers 16 and 17 are filled with a desiccant 19 to prevent condensation of the hollow layers 14 and 15. A Low-E film (low radiation film) 20 for improving heat insulation performance is formed on the hollow layer 14 of the single glass sheet 11 and the hollow layer 15 side of the single glass sheet 12 (for example, the surface on the indoor side). In addition, you may form this Low-E film | membrane on both surfaces of each glass plate 11,12,13.

  Each side of the laminated glass 13 constituting the multilayer glass 1 is fitted into the support member 2 made of hard resin. The support member 2 is an extruded material having an elongated S-shaped cross section along the side of the laminated glass 13, and has openings 3 and 6 that open in opposite directions to each other. The end of one side of 13 is inserted. In order to hold the inserted laminated glass 13 securely, the inner surface of the opening 3 of the supporting member 2 has fin-like portions 4 (four locations in FIG. 2) made of a soft resin, and the inserted laminated glass 13 is damaged. In order to prevent this, a protective pad 5 made of a soft resin is provided on the inner bottom surface of the opening 3 (the abutting surface against the laminated glass 13).

  When the support member 2 is mounted on the laminated glass 13, the other opening 6 of the support member 2 is covered with a cap 7. This cap 7 prevents the secondary seal from entering the opening 6 and closing the opening when the outer peripheral edge of the multilayer glass 1 is filled with the secondary seal 21 after the support member 2 is mounted on the laminated glass 13. Is to do. After filling the secondary seal 21, the cap 7 is removed. The opening 6 may be simply closed with a tape or the like instead of the cap 7.

  In this way, the multi-layer glass 1 on which the support member 2 is mounted is leaned so that one side of the multi-layer glass 1 is along the vertical frame 8 (or a pillar or other vertical member) which is a structural member. At this time, the peripheral edge portion of the laminated glass 13 covered with the support member 2 is not in contact with the frame 8, and the laminated glass 13 is in contact with the frame 8 due to shaking of the building during construction or after installation. It can be prevented from being damaged.

  Thereafter, an attachment member 9 such as a long aluminum flat bar (flat plate) having the same length in the longitudinal direction of the support member 2 is inserted into the opening 6 of the support member 2, and the other end of the attachment member 9 is inserted. The part is inserted into the opening 6 of the support member 2 mounted on the adjacent double-glazed glass 1. The attachment member 9 mounted across both the support members 2 is securely fixed to the vertical frame 8 through fixing means such as screws 10. At this time, the operator can simultaneously fix the mounting member 9 with the screw 10 while pressing the multilayer glass from the outside, so that the work on the inner side of the multilayer glass 1 becomes unnecessary, the work is simplified, and the workability is improved. Will improve. In this case, if the support member 2 is made of metal, it is possible to reduce the tightening force applied to the multilayer glass 1 when the support member 2 is fixed with the screw 10.

  In addition, as long as the attachment member 9 can be fixed, it can be applied to a structural member such as a building pillar other than the vertical frame 8. Alternatively, the support member 2 may be fitted into the single glass plate 12 and the multi-layer glass 1 may be fixed to the vertical frame 8 with the same structure.

  The joint portion between the adjacent multilayer glasses 1 and 1 is sealed with a silicon-based sealing material 23 after the backup material 22 is inserted. Thereby, since it becomes possible to use the multi-layer glass as the wall surface of the building without using a sash, it is possible to obtain a simple and good appearance without conspicuous joints. Moreover, since the glass plate 11, 12, 13 which forms the multilayer glass 1 to attach can use the glass plate of the same magnitude | size, it is not necessary to manufacture the special multilayer glass for using as a wall surface, Since multi-layer glass that is usually fitted and attached to a sash or the like can be used, the operation is simplified.

  In the present embodiment, the multi-layer glass 1 in which the three glass plates 11, 12, and 13 are overlapped is used. However, a multi-layer glass composed of two glass plates may be used. Multi-layer glass using two or more glass plates can also be applied.

  In addition, the attachment member 9 may not be long but may be a short and substantially rectangular piece. In this case, by forming the length of the short side of the mounting member 9 slightly smaller than the gap between the joints, the mounting glass 9, which is a piece piece, is placed after the adjacent multi-layer glass 1, 1 is leaned upright. It is inserted from the gap of the joint portion in such a direction that the short side is in the width direction of the gap of the joint portion, inserted to the depth of the opening portion 6, and then the attachment member 9 is rotated and fixed by screws or the like. Therefore, the long side of the mounting member 9 is shorter than the distance between the inner bottom surfaces of the opposing openings 6 of the supporting member 2 mounted on the adjacent double glazings 1 and 1, for example, the mounting member 9. The mounting member 9 is made to be able to rotate in the joint portion with a screw or the like inserted through the rotation center. Further, the support member 2 is not long and may be attached to a plurality of locations on each side of the laminated glass 13 as a piece piece having a short length. Both ends (upper and lower sides) of the multi-layer glass 1 mounted side by side on the wall are fixed with a sash or the like, or the mounting member 9 is formed in a stepped shape having an L-shaped cross section and one end is inserted into the opening 6 to make glass. The plate may be latched and held, and the other end may be fixed to the stand 8 with a screw 10 or an adhesive.

FIG. 3 is a plan view when the wall surface of the building is constructed by connecting the multiple glass layers in the horizontal direction using the multiple glass support structure according to the present invention.
As shown in the figure, only the sealing material 23 can be seen at the joint portion of the adjacent multilayer glass 1, 1 formed as the wall surface of the building, so the support frame does not protrude from the surface of the multilayer glass and continues in the horizontal direction. It becomes a multi-layer glass, and a wall surface with a good appearance can be obtained. When the multilayer glass 1 is stacked up and down to form a wall surface, for example, connection is made via a sash 24. In this case as well, the multi-layer glass supporting structure according to the present invention can be applied by using the beams of the building, and the wall surfaces can be formed by arranging the upper and lower multi-layer glass 1 without using the sash 24. .

FIG. 4 to FIG. 6 are schematic views showing the production process of the multilayer glass 1 used in the multilayer glass support structure according to the present invention.
Of the Low-E film 20 formed on the surface of the glass plate (8 mm single plate glass) 11 used on the outside as shown in FIG. 4A, the Low-E film in the vicinity of the peripheral portion where the spacer and the sealing material are arranged. 20 is peeled off (trimming). Next, as shown in (B), the spacers 16 with the primary seals 18 disposed on both sides are placed on the single glass plate 11 on the line of the roller conveyor 25 or the like.

  Next, as shown in (C), after placing a glass plate (5 mm single plate glass) 12 trimmed with the Low-E film 20 thereon, as shown in (D), the primary seal 18 is attached to both side surfaces. The spacer 17 arranged in the above is placed.

  As shown in FIG. 5E, a laminated glass 13 (two pieces of 3 mm single glass bonded together) is placed thereon. Thereafter, pressing is performed from both surfaces of the outer and inner glass plates to ensure the adhesion of the three glass plates by the primary seal 18. The glass plates stacked in this way are moved to a rack (not shown) or the like with a suction cup (not shown) or the like. Here, gas is injected into the hollow layer in consideration of heat insulation performance. This gas is filled from a corner key (not shown) or the like disposed at the corner between the glass plates 11, 12 and 13 together with the spacers 16 and 17 by a gas injector (not shown) or the like. 4A to 5E, the spacers may be sequentially arranged from the laminated glass 13 in the reverse order, and the glass plate 11 may be placed finally.

  After the gas injection, as shown in (F), the multi-layer glass 1 is placed flat on the work table 26 so that the glass plate (laminated glass 13) disposed on the indoor side faces down, and aligned. Each side of glass 13 (side on which the multi-layer glass support structure according to the present invention is applied) is inserted into opening 3 (see FIG. 2) of support member 2.

  Next, as shown to (G), the secondary seal | sticker is filled in the peripheral part of the multilayer glass 1. FIG. At this time, the secondary seal is filled from the nozzle 27. An opening width of about 4 mm is sufficient to insert the nozzle 27 for filling the secondary seal. For this purpose, the upper surface of the support member 2 and the upper surface of the glass plate 12 after the support member 2 is mounted on the glass plate 13 are sufficient. The width of the hollow layer 15 and the support member 2 is preferably provided so that a gap of about 4 mm is formed between the lower surface and the lower surface.

  As shown in FIG. 6 (H), the secondary seal 21 is filled in the peripheral portion of the multilayer glass 1. At this time, since the cap 7 is attached to the support member 2 and the opening 6 is covered with the cap 7, the sealing material does not hang down while filling the secondary seal 21 and does not enter the opening 6. Since the cap 7 only needs to prevent the sealing material from entering the opening 6, it is also possible to substitute the cap 6 by closing the opening 6 using an adhesive tape or the like.

  Thereafter, as shown in (I), the secondary seal 21 protruding from the end face of the multilayer glass 1 is removed using a spatula 28. Next, as shown in (J), the cap 7 is removed. The multilayer glass 1 formed in this way is loaded on a transport pallet (not shown) and transported to the site.
