Description

  The present invention relates to a multi-layer glass in which a plurality of plate glasses face each other at intervals.

  The multi-layer glass in which a plurality of plate glasses face each other at an interval is composed of, for example, a rectangular outer plate glass and a rectangular inner plate glass arranged in parallel at equal intervals around a square intermediate plate glass. Multi-layer glass is known. The multilayer glass has aluminum spacers interposed between the outer peripheral end portions of the intermediate plate glass and the outer peripheral end portions of the outer plate glass and the inner plate glass so as to be located inside the edge of each plate glass. The aluminum spacer has a hollow structure in which the end in the longitudinal direction along the edge of each plate glass is opened, and the inside is filled with a desiccant. Moreover, the hollow formed between outer plate glass and inner plate glass used as the outer peripheral part of multilayer glass is enclosed by the pair seal | sticker (for example, refer patent document 1).

JP 2000-8719 A

  When the spacer interposed between the plate glasses is made of aluminum as in the case of the multilayer glass as described above, the weight of the plurality of glasses cannot be supported by the spacer. For example, it is necessary to provide a reinforcing member made of steel, for example, to support the weight of the double-glazed glass or to improve the rigidity against wind load. For this reason, the shoji etc. provided with the double-glazed glass have a problem that the number of parts increases, so that the assembly is complicated and the weight and cost increase.

  This invention is made | formed in view of this subject, The place made into the objective is providing the multilayer glass which can support the dead weight and can improve the rigidity with respect to a wind load. is there.

In order to achieve such an object, the double-glazed glass of the present invention is a double-glazed glass used for a shoji, which is a steel interposed between a plurality of flat glass facing each other and a peripheral portion between the adjacent flat glasses. Or a stainless steel aggregate and a joining material for joining the plate glass and the aggregate, and the aggregate is fixed to a link mechanism that supports the shoji to support the plate glass. It is a multilayer glass.
According to such multi-layer glass, the adjacent plate glasses are joined to the peripheral portion between the plate glasses with steel or stainless steel aggregates interposed therebetween. It is joined by a rigid aggregate. For this reason, the multi-layer glass in which the high-stiffness glass and the aggregate having high strength and rigidity are joined is supported by the aggregate, so that the self-weight of the multi-layer glass can be obtained without using a wrinkle or a reinforcing member. It is possible to improve the rigidity against wind load.

In this multilayer glass, the aggregate is adjacent to the outer peripheral wall part exposed between the plate glasses on the peripheral end surface of the multilayer glass, and spaced apart from the outer peripheral wall part in the in-plane direction. Two facing portions facing each of the glass sheets, and two connecting portions connecting the outer peripheral wall portion and the two facing portions, respectively, have a groove shape opened toward the center side of the multilayer glass. It is desirable to have done.
According to such a multilayer glass, since the outer peripheral wall portion of the aggregate interposed between the adjacent glass plates is exposed on the peripheral end surface of the multilayer glass, it is possible to easily support the aggregate. . In addition, since the aggregate has a groove shape in which the outer peripheral wall portion, the two opposing portions, and the two connecting portions are open toward the center side of the multilayer glass, it is bent from, for example, a steel or stainless steel plate. It is possible to form by simple processing.

In such a multi-layer glass, it is desirable that the width at which the aggregate is exposed on the peripheral end surface is wider than the width at which the bonding material is exposed on the peripheral end surface with respect to the interval between the adjacent plate glasses.
According to such a multilayer glass, since the aggregate on which the multilayer glass is supported is more widely exposed, it is possible to easily secure a large part for supporting the multilayer glass. Moreover, since the width | variety in which a joining material is exposed is small, the quantity of a joining material can be reduced.

In such a multi-layer glass, the connecting portion is inclined so that a distance from the plate glass becomes narrower from the outer peripheral wall portion toward each of the facing portions, and a gap formed by the plate glass and the connecting portion. It is desirable that the above-mentioned bonding material is filled.
Conventionally, steel and stainless steel have a linear expansion coefficient close to that of glass as compared with aluminum that is used as a spacer interposed between plate glasses constituting a multilayer glass. For this reason, it is possible to suppress the distortion which arises in a joining material between an aggregate and plate glass when heated by sunlight etc. smaller than the case of aluminum. For this reason, it is a multi-layer glass as described above in which a bonding material is filled in a narrow portion between the connecting portion and the plate glass, which has an inclination in which the interval between the outer peripheral wall portion and each facing portion becomes narrower toward the plate glass. Even if it exists, it is possible to join plate glass and aggregate. That is, it is possible to join the plate glass and the aggregate with a small amount of bonding material without the bonding material being present on the outer peripheral side of the outer peripheral wall portion.

In this multilayer glass, it is desirable that a desiccant for dehumidifying the space between the glass sheets is provided in the space between the glass sheets.
According to such multi-layer glass, it is possible to dehumidify the space between the plate glasses partitioned by the aggregate more reliably and prevent the water droplets from adhering to the plate glass.

The plate glass 12 and the aggregate 13 are joined together by a sealant 19 as a joining material.

  Between the two glass sheets 12, the aggregate 13 provided on the four peripheral edges of each glass sheet 12 has the same cross-sectional shape. As shown in FIG. 3, the aggregate 13 includes an outer peripheral wall portion 13 a exposed between the two glass plates 12 of the multilayer glass 14 and the peripheral end surface 14 a of the multilayer glass 14, and the outer peripheral wall portion 13 a and the in-plane Two facing portions 13b that are spaced apart in the direction and face each of the two glass plates 12, and two connecting portions 13c that respectively connect the outer peripheral wall portion 13a and the two facing portions 13b are the multilayer glass 14. It has a groove shape that is open toward the center side. The aggregate 13 is formed by bending a steel plate material by press working, and two facing portions 13b facing each of the two sheet glasses 12 are double-folded by roll forming.

  The outer peripheral wall portion 13a is formed with a width narrower than the interval between the two plate glasses 12, and is opposed to both sides in the prospective direction of the outer peripheral wall portion 13a through a seal 26 that is airtight / watertight with the plate glass 12. A connecting portion 13c that connects the portion 13b is formed. For this reason, the connecting portion 13c has an inclination in which the distance from the plate glass 12 becomes narrower from the outer peripheral wall portion 13a toward each facing portion 13b, and a gap formed by each plate glass 12 and the connecting portion 13c. Sealant 19 is filled. At this time, the width of the multilayer glass 14 in the thickness direction between the outer peripheral wall portion 13a of the aggregate 13 exposed on the peripheral end surface 14a of the multilayer glass 14 and the sealant 19 is wider in the aggregate 13 than in the sealant 19. ing.

  In the space between the two glass plates 12 of the multilayer glass 14, there are two sheets between the facing portion 13 b of the aggregate 13 below the multilayer glass 14 and between the facing portion 13 b of the left aggregate 13. A desiccant 25 for dehumidifying the space between the glass plates 12 is provided. Further, the double glazing 14 accommodated in the brazing material 16 is formed on the both end sides in the finding direction with the lower peripheral end surfaces 11a, 12a, the inner extending portion 15c, and the outer extending portion 15d, respectively. A setting block 17 is interposed therebetween.

  The brazing material 16 includes an indoor cover portion 16a that covers the peripheral edge portion of the multilayer glass 14 from the indoor side, an outdoor cover portion 16b that covers the peripheral edge portion of the multilayer glass 14 from the outdoor side, a lower end of the indoor cover portion 16a, and a chamber An outer peripheral cover portion 16c that connects the lower end of the outer cover portion 16b, an outer peripheral protrusion portion 16d that protrudes to the outer peripheral side on the outdoor side of the outer peripheral cover portion 16c and covers the frame 2 when the shoji 10 is closed; have. The outer peripheral cover portion 16c has two protruding pieces 16e that protrude inward along the longitudinal direction of the brazing material 16 at a position allocated from the center in the prospective direction.

  In the brazing material 16, the two protruding pieces 16 e are brought into contact with the outer peripheral wall portion 13 a of the aggregate 13 so as to accommodate the peripheral edge portion of the multilayer glass 14, and the peripheral end surface 12 a of each plate glass 12 and the two protruding portions. Thermally expandable graphite 17 is interposed between the outdoor side of the piece 16e and the outer peripheral cover part 16c on the outdoor side, and is fixed between the two protruding pieces 16e by screws 18 from the outer peripheral side. As shown in FIG. 4, the screw 18 has a sealing material 18 a applied to the outer peripheral surface of the screw portion 18 b, and when screwed to the aggregate 13, the screw 18 and the aggregate 13 are screwed together. The gap is sealed with a sealing material 18a. Further, a screw hole 13d provided in the aggregate 13 and screwed into the screw 18 is covered and sealed with a sheet 29 made of butyl rubber. For this reason, in the multi-layer glass 14, the space between the two sheet glasses 12 is kept sealed even if the brazing material 16 is screwed to the aggregate 13.

  The shoji 10 includes a saddle member 16 covering the upper and lower peripheral edges of the multilayer glass 14, a link mechanism 20 interposed between the upper frame 3 and the lower frame 4, and a handle 6 as shown in FIG. Are connected to the aggregate 13 by screws and are supported to be freely opened and closed. Moreover, it is comprised so that the shoji 10 may be supported by the frame 2 in the closed state by the lock mechanism 31 (FIG. 2) screwed to the aggregate 13 of the door-end side of the shoji 10. FIG. The screw part of the screw that fixes the connecting part 30 and the lock mechanism 31 to the aggregate 13 is also provided with a sealing material, and the hole into which the screw is screwed is covered with a sheet 29 made of butyl rubber. It is sealed.

  Since the link mechanisms 20 provided above and below the shoji 10 are members of the same structure, in the following description, the link mechanism 20 provided below the shoji 10 will be described as an example.

  As shown in FIG. 6, the lower link mechanism 20 includes a frame fixing link 21 fixed to the lower frame 4 with screws, a shoji fixing link 22 fixed to the lower surface of the shoji 10 with screws 18, and one end. 23a is connected to the right end portion 21a of the frame fixing link 21, the other end 23b is pivotally attached to the shoji fixing link 22, and one end 24a is connected to the left end portion 21b of the frame fixing link 21, The other end 24b has the 2nd connection link 24 each pivotally attached to the site | part 22b by the side of the door opposite to the shoji fixed link 22. FIG.

  The shoji 10 attached to the frame body 2 via the link mechanism 20 has the other end 23b of the first connecting link 23 pivoted to the frame fixing link 21 and the other end 24b of the second connecting link 24 pivoted. The shoji fixing link 22 is supported by the aggregate 13 to which the shoji fixing link 22 is fixed. At this time, the screw 18 for fixing the shoji fixing link 22 is coated with the sealing material 18a on the outer peripheral surface of the screw portion, and when the screw is screwed to the aggregate 13 together with the shoji fixing link 16, A gap between the aggregate 13 and the outer peripheral surface of the screw portion of the screw 18 is sealed by the sealing material 18a. For this reason, the space between the glass plates 12 surrounded by the aggregate 13 is maintained in a sealed state.

  According to the glass window 1 of the present embodiment, adjacent plate glasses 12 are joined to peripheral portions between the plate glasses 12 with steel or stainless steel aggregates 13 interposed therebetween, so that adjacent plate glasses are joined together. 12 is joined by an aggregate 13 having high strength and rigidity. For this reason, the multi-layer glass 14 in which the plate glass 12 having high rigidity and the aggregate 13 having high strength and rigidity are joined together is supported by the aggregate 13, so that the double-layer glass 14 is used without using a ridge or a reinforcing member. It is possible to support the dead weight of the layer glass 14 and to improve the rigidity against wind load.

  Moreover, since the outer peripheral wall part 13a of the aggregate 13 interposed between the mutually adjacent plate glasses 12 is exposed to the peripheral end surface 14a of the multilayer glass 14, the aggregate 13 can be supported easily. Further, the aggregate 13 has a groove shape in which the outer peripheral wall portion 13a, the two opposing portions 13b, and the two connecting portions 13c are opened toward the center side of the multilayer glass 14, so that, for example, steel or stainless steel is used. It is possible to form the plate material by simple processing such as bending.

  Further, since the aggregate 13 on which the multilayer glass 14 is supported is exposed more widely than the sealant 19 on the peripheral end surface 14a of the multilayer glass 14, a large part for supporting the multilayer glass 14 is secured and easily supported. It is possible. Moreover, since the width | variety in which the sealant 19 is exposed is small, the quantity of the sealant 19 can be reduced.

  Steel and stainless steel have a linear expansion coefficient close to that of glass, which is conventionally used as a spacer for multilayer glass. For this reason, in the case of aluminum, the distortion generated in the sealant 19 filled in the gap formed by each plate glass 12 and the connecting portion 13c between the aggregate 13 and the plate glass 12 when heated by sunlight or the like is used. It is possible to keep it smaller. For this reason, the sealant 19 is filled in a narrow portion between the connecting portion 13c and the plate glass 12 that forms an inclination in which the distance from the plate glass 12 becomes narrower from the outer peripheral wall portion 13a toward each facing portion 13b. Even if it is the multilayer glass 14 like this, it is possible to join the plate glass 12 and the aggregate 13. That is, the plate glass 12 and the aggregate 13 can be joined with a small amount of sealant 19 without filling the sealant 19 on the outer peripheral side of the outer peripheral wall portion 13a.

  Further, since the desiccant 25 for dehumidifying the space between the plate glasses 12 is provided in the space between the plate glasses 12, water droplets on the inner surface of the plate glass 12 are more reliably dehumidified. Can be prevented.

  In the said embodiment, although the example which comprised the multilayer glass 14 with two sheet glass was demonstrated, glass was formed integrally by making 3 or more sheet glass mutually faced at intervals, 2 sheets A resin plate may be interposed between the above plate glasses. Moreover, the plate glass which comprises the multilayer glass 14 may be the structure which combined low radiation glass, meshed glass, float glass, etc. Furthermore, the collar member 16 is not limited to a synthetic resin, and may be made of aluminum, a composite material of an aluminum material and a synthetic resin material, or wooden.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
