Description

  The present invention relates to a multi-layer glass panel provided in an opening device used in a building opening of a house or public facility, a shoji equipped with the multi-layer glass panel, and an opening device.

  As for an opening device such as a sash window provided in a building opening, a device that can be opened and closed can freely communicate with or shut off from the outside, and can enter and exit a person or an object, and can ventilate. Regardless of whether or not it can be opened and closed, many of the opening devices use multi-layer glass panels, improving heat insulation and sound insulation, and also using a light-transmitting property of glass in a closed position. Light can be taken into the room, and the indoor environment can be improved, such as brightening and warming the room.

  Such a multi-layer glass panel is configured such that its outer peripheral portion is surrounded by a frame or ridge made of metal or resin. In that case, in order to ensure airtightness and watertightness between the frame or ridge and the multi-layer glass panel, a seal member made of resin or the like is disposed at the contact portion between the frame or casket and the multi-layer glass panel. Examples of the sealing member include a glazing channel.

  However, when a large amount of heat is applied to the opening device due to a fire or the like, the sealing member tends to melt first and disappear due to the properties of various materials used in the opening device. If the sealing member disappears, the multi-layer glass panel may be decomposed, or there may be communication between the inside and outside of the room where the sealing member disappears even if it is not disassembled. There is. As means for preventing the spread of such flames and smoke, techniques such as Patent Documents 1 and 2 are disclosed. According to Patent Documents 1 and 2, using a foamable caulking material, a foamable flame barrier material (Patent Document 1), and a thermal expansion material (Patent Document 2), indoor and outdoor due to decomposition of the multilayer glass panel and disappearance of the seal member Communication is prevented.

  Such an effect | action and gain of this invention are clarified from the form for implementing invention demonstrated below. Hereinafter, the present invention will be described based on embodiments shown in the drawings. However, the present invention is not limited to these embodiments.

  FIG. 1 is a front view of a shoji 10 for explaining the first embodiment. 2 is a cross-sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG. FIG. 4 shows an enlarged view (FIG. 4A) focusing on the left end portion of FIG. 2 and an exploded view (FIG. 4B).

  The shoji 10 includes a multilayer glass panel 11 and a housing 20. The multilayer glass panel 11 includes plate glasses 12 and 13, a spacer 14, a panel sealing material 15, a glazing channel 16, a heating expansion body 17 as a sealing means, and a reinforcing member 18. Moreover, the housing 20 has long vertical rods 21 and 22, an upper horizontal rod 23, and a lower horizontal rod 24, which are combined in a rectangular frame shape. Each component will be described below.

First, the multilayer glass panel 11 will be described.
The plate glasses 12 and 13 are both rectangular plate-like glass panels, and are arranged side by side with a predetermined interval so that the plate surfaces face each other. Although the kind of plate glass to be used is not particularly limited, from the viewpoint of fire prevention performance, in this embodiment, the plate glass 12 is a meshed glass in which a linear metal is embedded, and the plate glass 13 is a LOW-E glass. did. Moreover, it can replace with this and can use heat-resistant tempered glass for plate glass 12,13. Thus, by using glass with high fireproof performance for the plate glasses 12 and 13, even when heat is applied to the multi-layer glass panel 11 due to a fire or the like, the glass itself is prevented from cracking and collapsing for a longer time. Is possible.

  The spacer 14 is disposed along the sides of the plate glasses 12 and 13 slightly inside the outer peripheral end portion of the space formed by the gap between the plate glass 12 and the plate glass 13. Therefore, the spacer 14 is formed in a rectangular frame shape between the glass plates 12 and 13. A known spacer can be used as the spacer 14, and the main function is to maintain the gap between the glass sheet 12 and the glass sheet 13 at a predetermined size. However, by including a desiccant in the spacer 14, the inside of the space surrounded by the spacer 14 and the plate glasses 11 and 12 can be maintained at an appropriate humidity.

  The inter-panel sealing material 15 is filled in the outer peripheral end portion of the gap that is outside the spacer 14 in the gap between the plate glass 12 and the plate glass 13. The inter-panel sealing material 15 has a main function of maintaining water tightness (sealing property) while firmly bonding and fixing the plate glass 12 and the plate glass 13. From this point of view, it is preferable to use a silicon-based or polysulfide-based adhesive as the inter-panel sealing material 15.

  In addition, in this embodiment, although the example which comprises two sheet glass 12 and 13 was shown in the multilayer glass panel 11, it is not limited to this, It is equipped with three or more sheet glass, Also good.

  The glazing channel 16 is a long member provided so as to cover the ends of the glass plates 12 and 13 and the gaps formed by the glass plates 12 and 13 and to surround the glass plates 12 and 13, and is orthogonal to the longitudinal direction. A cross section appears in FIGS. Here, “the end portion of the gap between the plate glasses 12 and 13 and the plate glasses 12 and 13” includes the end surfaces of the plate glasses 12 and 13, and the outer side surfaces of the plate glasses 12 and 13 (surfaces where the plate glasses 12 and 13 do not face each other). It is a concept including an outer peripheral end. In this embodiment, a known glazing channel can be used. As can be seen from FIGS. 2 to 4, the glazing channel 16 has a substantially U-shaped cross section, and includes a bottom piece and two standing pieces erected in the same direction from both ends of the bottom piece. Accordingly, a gap is formed between the standing pieces, and an opening leading to the inside having a U-shaped cross section is formed on the side where the bottom piece is not disposed. And it arrange | positions so that the edge part of the plate glass 12 and 13 may be inserted between the standing-up pieces from the said opening part.

  As the material of the glazing channel 16, a known material for the glazing channel can be used, and examples thereof include a vinyl chloride-based material and a silicon-based material. In addition, it is possible to combine hard and soft materials for these materials, or to use only soft materials.

As shown in FIGS. 2 to 4, the heating expansion body 17 is a long and thin plate-like member extending along the longitudinal direction of the glazing channel 16 in a normal state in this embodiment. However, the heating foam 17 is flame retardant and is configured to expand and increase in volume when heated to a predetermined temperature. Although the specific expansion start temperature is not particularly limited, it is preferably about 150 ° C. in accordance with the building standard method and the heating curves of the same construction ordinance.
Further, the expansion ratio is not particularly limited, but is preferably 10 to 40 times.
A specific material of the heating expansion body 17 is not particularly limited as long as it has such performance, and a known material can be used. This is, for example, a material containing a thermal foam such as graphite or carbon fiber, and examples of the base material include those using epoxy, vinyl chloride, butyl and the like.

  The reinforcing member 18 is a long member extending along the longitudinal direction of the glazing channel 16 so as to cover the end portions of the glass plates 12 and 13 arranged and the end portions of the gaps between the glass plates 12 and 13 and the glazing channel 16 from the outside. The cross section perpendicular to the longitudinal direction appears in FIGS. As can be seen from FIGS. 2 to 4, the reinforcing member 18 has a substantially U-shaped cross section, and includes a bottom piece and two standing pieces erected in the same direction from both ends of the bottom piece. Accordingly, a gap is formed between the standing pieces, and an opening leading to the inside having a U-shaped cross section is formed on the side where the bottom piece is not disposed. And it arrange | positions so that the edge part of the glass plates 12 and 13 and the glazing channel 16 may be inserted between the standing-up pieces from the said opening part. Thereby, even if heat from a fire or the like is applied to the shoji 10, the plate glasses 12 and 13 remain in the housing 20, and it is possible to more reliably prevent the plate glasses 12 and 13 from being detached from the housing 20 and collapsing. .

  The material of the reinforcing member 18 is not particularly limited as long as it has high heat resistance and can hold the glass plates 12 and 13. An example of this is a metal. Among these, aluminum is preferable from the viewpoint of light weight.

Next, the casing 20 will be described. As described above, the housing 20 has the long vertical rods 21 and 22, the upper horizontal rod 23, and the lower horizontal rod 24, which are combined in a rectangular frame shape. The vertical raft, the upper horizontal bar, and the lower horizontal bar need only be able to form a casing, and the specific cross-sectional shape thereof is not limited. That is, an appropriate cross-sectional shape is selected depending on the type of opening device to which the shoji is applied. Since the casing 20 of this embodiment is used for the sliding door type opening device 30 as will be described later (see FIGS. 5 and 6), the vertical gutter 21 is the door-end gutter, the vertical gutter 22 is the summon gutter, and the upper side. The collar 23 and the lower horizontal collar 24 function as a collar guided by the upper frame 34 and the lower frame 35.
However, the vertical rods 21 and 22, the upper horizontal rods 23, and the lower horizontal rods 24 constituting the casing 20 are all the reinforcing member 18, the heating expansion body 17, at least a part of the glazing channel 16, and the sheet glass 12. 13 is provided with a groove portion into which the end portion can be inserted (for example, the groove portion 21a in FIG. 4B).

The shoji 10 is formed by combining the above structural members as follows, for example.
That is, as can be seen from FIG. 2 to FIG. 4, the glass plates 12 and 13, the end of the gap between the glass plates 12 and 13, and the inter-panel sealing material 15 are inserted inside the U-shape of the glazing channel 16, It is arranged so as to be surrounded by the glazing channel 16.

On the other hand, the reinforcing member 18 is disposed in the groove portions (for example, the groove portion 21a shown in FIG. 4B) formed in the vertical rods 21, 22, the upper horizontal rod 23, and the lower horizontal rod 24. At this time, each piece constituting the reinforcing member 18 is arranged so as to be along the inner surface of the groove of each ridge (21, 22, 23, 24), and the glazing channel 16 or the like can be inserted into the opening of the reinforcing member 18. .
Moreover, when arrange | positioning the reinforcement member 18, it is preferable to fix to each collar (21, 22, 23, 24) using fixing members, such as a screw and a screw.

A heat expansion material 17 is disposed at the bottom of the reinforcing member 18 having a U-shaped cross section. In that case, it is preferable that the heating expansion body 17 is fixed to the reinforcing member 18 with a fixing member such as a screw or a screw.
And it arrange | positions so that the edge part of the glazing channel 16 and the plate glass 12 and 13 may be inserted in the groove part (21a etc.) of each ridge (21, 22, 23, 24) and the reinforcement member 18. FIG.

  Next, the opening device 30 provided with the shoji 10 will be described. 5 and 6 are cross-sectional views of the opening device 30 provided with the shoji 10. FIG. 5 shows a horizontal cross section and FIG. 6 shows a vertical cross section. In FIG. 5, the upper side of the paper indicates the outdoor side and the lower side of the paper indicates the indoor side. In FIG. 6, the left side of the drawing represents the outdoor side and the right side of the drawing represents the indoor side. In the present embodiment, the opening device 30 is a so-called sliding door sash window. The opening device 30 includes a frame 31 arranged along the edges of the four sides of the building opening, and two shojis 10 that are provided inside the frame 31 and open and close in a sliding door manner. The opening device 30 will be described with reference to FIGS. 5 and 6.

The frame 31 has a longitudinal frame 32, 33 arranged in parallel with a predetermined interval on the left and right sides, and a length that is horizontally disposed on the upper and lower sides across the ends of the vertical frames 32, 33. An upper horizontal frame 34 and a lower horizontal frame 35 which are scale members are provided, and these are combined in a frame shape. The vertical frames 31, 32, the upper horizontal frame 34, and the lower horizontal frame 35 are only required to form a frame of the opening device, and the specific cross-sectional shape thereof is not limited. That is, an appropriate cross-sectional shape is formed depending on the type of opening device to which the shoji is applied. In this embodiment, since it is a sliding door type sash, the upper horizontal frame 34 is provided with guide pieces 34a and 34b that are inserted into the upper horizontal flange 23 of the shoji 10 and guide the upper horizontal fence 23, and the lower horizontal frame 35 has Rail pieces 35a and 35b are provided on which the door pulley 10a provided on the lower lateral arm 24 of the shoji 10 is placed and function as rails.
Further, from the viewpoint of improving heat insulation, the frame body 31 may be formed of a resin, and cover members 32a, 33a, 34c, and 35c provided on the inner surface of the frame body 31 may be attached.

  Since the shoji 10 has been described above, the description thereof is omitted here. However, as for the two shojis 10 provided in the opening device 30, the cross-sectional shape of the heel differs between the shojis 10 arranged on the indoor side and the shojis 10 arranged on the outdoor side. In this embodiment, the vertical gutter 21 functions as a doorside gutter and the vertical gutter 22 functions as a summon gutter.

  The opening device 30 is formed by arranging the two shojis 10 in the frame of the frame 31 in a sliding door manner. That is, the upper horizontal frame 23 of the shoji 10 is guided by the guide pieces 34 a and 34 b of the upper horizontal frame 34, and the door pulley 10 a provided on the lower horizontal frame 24 of the shoji 10 is mounted on the rail pieces 35 a and 35 b of the lower horizontal frame 35. By being placed and guided, the shoji 10 can be opened and closed in a sliding door manner.

Next, the effect | action by the multilayer glass panel 11 is demonstrated. FIG. 7 is a diagram for explaining the operation, and shows a view from the same viewpoint as FIG.
When the opening device 30 including the multilayer glass panel 11 is heated by a fire or the like and reaches a predetermined temperature, a member formed of the resin material included in the multilayer glass panel 11 may melt and disappear. . In particular, the inter-panel sealing material 15 generates combustible gas due to its nature. On the other hand, the multilayer glass panel 11 is provided with a heating expansion body 17, and the heating expansion body 17 functioning as a sealing means expands due to heat from a fire or the like, and as shown in FIG. It enters between the plate glass 13. Thereby, the generated combustible gas can be sealed and confined between the glass sheets 12 and 13. Therefore, it is possible to prevent the combustible gas from flowing out and igniting.
As described above, according to the present invention, the combustible gas is contained between the multilayer glasses to prevent the ignition thereof.

Further, when the reinforcing member 18 is provided as in the present embodiment, even when the glazing channel 16 disappears, the multilayer glass panel 11 can be more reliably held in the housing 20.
In addition to this, if a glass-containing glass or a heat-resistant tempered glass is applied to at least one of the plate glasses 12 and 13, the multilayer glass panel 11 is reliably held in the casing 20.

  FIG. 8 shows a diagram corresponding to FIG. 4A among the shojis 10 ′ and 10 ″ according to the modification. FIG. 8A shows the shoji 10 ′ and FIG. 8B shows the shoji 10 ″. Represents. In the shoji 10 ′ and shoji 10 ″, at least one of the heating expansion body and the reinforcing member is different from the shoji 10 among the multi-layer glass panels 11 ′ and 11 ″, and the other configurations are the same as the shoji 10. Common parts are denoted by the same reference numerals and description thereof is omitted.

  In the shoji 10 ′, a heating expansion body 17 ′ is disposed between the end portions of the glass sheets 12 and 13 and the glazing channel 16. Such an arrangement of the heating expansion body 17 ′ also provides the same effect as described above.

  The shoji 10 ″ includes a heating expansion body 17 ″ and a reinforcing member 18 ″. In this embodiment, the heating expansion body 17 ″ has a width before expansion (normal time) (in the vertical direction of FIG. 8B). The size) is shorter than the heating expansion bodies 17 and 17 ', and is brought closer to one side than the center of the thickness of the multilayer glass panel 11 "(the size in the vertical direction in FIG. 8B). Thus, the arrangement form of the heating expansion body is not particularly limited as long as it can appropriately enter between the glass sheets during the expansion and seal the combustible gas.

  Further, as can be seen from FIG. 8B, the reinforcing member 18 ″ of this example is a long member having an L-shaped cross-sectional shape and extending along the longitudinal direction of the glazing channel 16. One of the cross-sections 18 ″ is L-shaped, and the other piece is arranged in the direction along the end surface of the glass sheets 12 and 13, and the other piece is arranged in the direction along the plate surface of the glass sheet 12. Thus, even if the reinforcing member is disposed only on the plate glass 12 side or the plate glass 13 side, the plate glass 12 and 13 remains in the housing 20 even when the shoji 10 ″ is heated by a fire or the like, and the plate glass 12 and 13 Can be more reliably prevented from falling off the casing 20 and collapsing.

  The material of the reinforcing member 18 ″ is not particularly limited as long as it has high heat resistance and can hold the glass sheets 12 and 13. For example, a metal can be used. Aluminum is preferable from a certain viewpoint.

In addition to the above-described modified examples, it is possible to apply modified forms as long as they do not contradict the gist of the present invention. For example, the cross-sectional shape of the heating expansion body is not necessarily formed in a rectangular shape, and may be formed in a predetermined cross-sectional shape. For example, it is possible to form a glazing channel with a heated expansion body. Alternatively, the heat expansion body can be extruded and integrated into the glazing channel. According to these, since it can serve two functions, the number of members can also be reduced. Moreover, the longitudinal direction of the heating expansion body does not need to be continuous, and may be provided intermittently.
The reinforcing member is preferably provided in order to achieve the above effect, but it is not necessarily provided. For example, instead of providing a reinforcing member, the same effect can be obtained by increasing the strength of the heel itself by increasing the thickness of at least a part of the heel piece.

  FIGS. 9 and 10 are views for explaining the second embodiment. FIG. 9 is a horizontal sectional view of the opening device 40, and FIG. 10 is a vertical sectional view of the opening device 40. In FIG. 9, the upper side of the paper represents the outdoor side, the lower side of the paper represents the indoor side, and in FIG. This embodiment is a so-called opening device that is prohibited from opening and closing.

  The opening device 40 includes a frame body 41, plate glasses 46 and 47, a spacer 48, an inter-panel seal material 49, seal materials 50 and 51, a heating expansion body 52, and reinforcing members 53 and 54.

The frame body 41 has a longitudinal frame 42 and 43 that are arranged in parallel at a predetermined interval on the left and right sides, and a length that is horizontally disposed on the upper and lower sides across the ends of the vertical frames 42 and 43. An upper horizontal frame 44 and a lower horizontal frame 45 which are scale members are provided, and these are combined in a frame shape. The vertical frames 41 and 42, the upper horizontal frame 44, and the lower horizontal frame 45 only need to be able to form a frame of the opening device, and their specific cross-sectional shapes are not limited. In other words, in the present embodiment, any cross-sectional shape that can constitute the fitting window may be used. However, the vertical frames 41 and 42, the upper horizontal frame 43, and the lower horizontal frame 44 constituting the frame body 41 are all at least a part of the reinforcing members 53 and 54, the heating expansion body 52, and the sealing materials 50 and 51, and A groove portion into which the end portions of the plate glasses 46 and 47 can be inserted is provided.
Further, from the viewpoint of improving heat insulation, the frame body 41 may be formed of a resin, and cover members 42a, 43a, 44a, and 45a provided on the inner surface of the frame body 41 may be attached.

  The plate glasses 46 and 47 are common to the above-described plate glasses 12 and 13, and the spacer 48 and the inter-panel seal material 49 are common to the above-described spacer 14 and inter-panel seal material 15, respectively, so description thereof is omitted here.

  The seal material 50 is disposed between the plate glass 46 and the inner surface of the groove portion of the frame body 41, and the seal material 51 is a long member disposed between the plate glass 47 and the groove portion of the frame body 41 and orthogonal to the longitudinal direction. 9 and 10 show cross sections. Thereby, the water-tight airtightness of the plate glass 46 and 47 and the frame 41 is ensured. As such a sealing material, a known material can be used, and it may be called a bead or the like.

  The heating expansion body 52 is the same as the heating expansion body 17 described above, and thus the description thereof is omitted here.

  As can be seen from FIG. 9, the reinforcing member 53 is a member having a substantially U-shaped cross section, and is a member extending in the back / front direction of FIG. 9. On the other hand, as can be seen from FIG. 10, the reinforcing member 54 is a member having an L-shaped cross section, and is a member extending in the rear / front direction of FIG. 10. With such reinforcing members 53 and 54, the plate glass 46 and 47 stays in the frame body 41 even when heat is applied to the opening device 40 due to fire or the like, and the plate glasses 46 and 47 are separated from the frame body 41 and collapse. It becomes possible to prevent reliably. The material of the reinforcing members 53 and 54 is not particularly limited as long as it has high heat resistance and can hold the plate glasses 46 and 47. An example of this is a metal. Among these, aluminum is preferable from the viewpoint of light weight.

The opening device 40 including the above-described constituent members is formed by combining the constituent members as follows, for example.
That is, as can be seen from FIGS. 9 and 10, the spacer 48 is disposed at the end of the gap so as to form a gap between the plate glass 46 and the plate glass 47, and the inter-panel sealing material 49 is filled on the outer side. Has been. Thus, the glass plates 46 and 47, the spacer 48, and the inter-panel seal material 49 are integrated.

On the other hand, reinforcing members 53 and 54 are arranged in grooves formed in the vertical frames 42 and 43 and the lower horizontal frame 45 in the frame body 41. One piece of the reinforcing member 53 is arranged in a direction along the end surfaces of the plate glasses 46 and 47, and two opposing pieces are arranged outside the respective plate surfaces of the plate glasses 46 and 47 in a direction along the plate surface. On the other hand, one piece of the reinforcing member 54 is arranged in a direction along the end surfaces of the plate glasses 46 and 47, and the other piece is arranged outside the plate surface of the plate glass 46 in a direction along the plate surface.
Further, when the reinforcing members 53 and 54 are arranged, it is preferable to fix the frame body 41 using a fixing member such as a screw or a screw.

Here, in the groove portion where the reinforcing members 53 and 54 are disposed, the heating expansion body 52 is provided between the reinforcing members 53 and 54 and the end surfaces of the plate glasses 46 and 47. In that case, it is preferable that the heating expansion body 52 is fixed to the frame body 41 and the reinforcing members 53 and 54 with fixing members such as screws and screws.
And the plate glass 46 and 47 integrated inside each groove part of the frame 41 is inserted, and the sealing materials 50 and 51 are arrange | positioned between the plate glass 46 and 47 and the frame 41, and watertight airtightness was achieved. Yes.

  Such an opening device 40 has the same effect as the first embodiment.

  Next, a third embodiment will be described. 11 is a view corresponding to FIG. 2 in the shoji 60 included in the third embodiment, FIG. 12 is a view corresponding to FIG. 3, and FIG. 13 is a view corresponding to FIG.

  The shoji 60 includes a multi-layer glass panel 61 and a housing 70. The multilayer glass panel 61 includes plate glasses 62 and 63, a spacer 64, an inter-panel sealing material 65, a glazing channel 66, a heating expansion body 67 as a sealing means, and a reinforcing member 68. The casing 70 has long vertical rods 71 and 72, an upper horizontal rod 73, and a lower horizontal rod 74, which are combined in a rectangular frame shape. Each component will be described below.

First, the multilayer glass panel 61 will be described.
Since the plate glass 62 and 63, the spacer 64, and the panel sealing material 65 are the same as the plate glass 12 and 13, the spacer 14, and the panel sealing material 15 which were demonstrated in 1st embodiment, respectively, description is abbreviate | omitted here.

  The glazing channel 66 is a long member provided so as to cover the ends of the gap between the plate glasses 62 and 63 and the plate glasses 62 and 63 and to surround the plate glasses 62 and 63, and is orthogonal to the longitudinal direction. The cross section appears in FIGS. Here, “the end portion of the gap between the plate glasses 62 and 63 and the plate glasses 62 and 63” includes the end surfaces of the plate glasses 62 and 63, and further, the outer surface of the plate glasses 62 and 63 (the surface where the plate glasses 62 and 63 do not face each other). It is a concept including an outer peripheral end.

As can be seen from FIG. 13B, the glazing channel 66 has a substantially U-shaped cross section, and includes a bottom piece 66a and two standing pieces 66b standing in the same direction from both ends of the bottom piece 66a. Yes. Therefore, a gap is formed between the standing pieces 66b, and an opening leading to the inside having a U-shaped cross section is formed on the side where the bottom piece 66a is not disposed. In addition, seal pieces 66c and 66c that are provided to face each other so as to narrow the opening are disposed at the opening side end of the standing piece 66b. Further, fin-shaped portions 66d and 66e are formed on the surfaces of the standing piece 66b facing each other.
In addition, the standing piece 66b has a hole 66f penetrating in the thickness direction. A plurality of holes 66f are provided intermittently in the longitudinal direction of the standing piece 66b.

  In this embodiment, the aspect which provided the hole intermittently in all the glazing channels arrange | positioned at 4 round each side of plate glass was demonstrated. However, the present invention is not limited to this. Many holes are provided in the glazing channel arranged on the lower side of the glass sheet, and at least one hole is provided in any one of the glazing channels arranged on the other three sides. It may be an embodiment. According to this, the number of holes can be reduced. At this time, the hole provided in the glazing channel arranged on the lower side can be the drain hole, and the hole provided in any of the glazing channels arranged on the other three sides can be the outside air introduction hole.

Further, a protrusion 66g that stands on the same side as the standing piece 66b is provided in the center of the width of the bottom piece 66a in the width direction (vertical direction in FIG. 13). A stopper 66h is provided at the tip of the protrusion 66g so as to swell.
The protrusion 66g may be formed over the entire length of the glazing channel 66 in the longitudinal direction, but is not necessarily limited to this, and may be a part or may be formed intermittently. For example, you may provide a protrusion part only in the glazing channel arrange | positioned at the vertical side of a plate glass among the glazing channels arrange | positioned at each side of 4 sides of plate glass, and is formed in a rectangular frame shape. Conversely, a protrusion may be provided only in the glazing channel arranged on the side of the plate glass.
Examples of the material of the glazing channel 66 include vinyl chloride and silicon materials. In addition, it is possible to combine hard and soft materials for these materials, or to use only soft materials.

In the present embodiment, the heating expansion body 67 is an elongated plate-like member that has a rectangular cross section and extends along the longitudinal direction of the glazing channel 66 as shown in FIGS. However, the heated foam 67 is flame retardant and is configured to expand and increase in volume when heated to a predetermined temperature, as will be described later. Although the specific expansion start temperature is not particularly limited, it is preferably about 150 ° C. in accordance with the building standard method and the heating curves of the same construction ordinance.
Further, the expansion ratio is not particularly limited, but is preferably 10 to 40 times.
The specific material of the heating expansion body 67 is not particularly limited as long as it has such a performance, and a known material can be used. This is, for example, a material containing a thermal foam such as graphite or carbon fiber, and examples of the base material include those using epoxy, vinyl chloride, butyl and the like.

As can be seen from FIGS. 11 to 13, the reinforcing member 68 is a member having an L-shaped cross section and extending in the back / front direction of the paper surface, and one piece thereof extends along the end surfaces of the glass sheets 62 and 63. The other piece is arranged in the direction along the plate surface outside the plate glass 62 as well as the direction.
With such a reinforcing member 68, even if heat is applied to the shoji 60 due to a fire or the like, the plate glasses 62 and 63 remain in the casing 70, and the plate glasses 62 and 63 are more reliably prevented from being detached from the casing 70 and collapsing. It becomes possible. The material of the reinforcing member 68 is not particularly limited as long as it has high heat resistance and can hold the glass plates 62 and 63. An example of this is a metal. Among these, aluminum is preferable from the viewpoint of light weight.

  Next, the housing 70 will be described. As described above, the housing 70 has the long vertical rods 71 and 72, the upper horizontal rod 73, and the lower horizontal rod 74, which are combined in a rectangular frame shape.

  The downspout 71 is a downspout that functions as a door toe in this embodiment, as will be described later. The vertical rod 71 has a piece 71b as a prospective piece extending in the prospective direction in the cross section shown in FIGS. Each piece 71b is provided with a piece 71c as an outdoor piece extending in the direction of finding and a piece 71d as an indoor piece at each of both ends in the prospective direction. At both ends of the pieces 71c and 71d in the direction of finding, the portions sandwiched between the pieces 71c and 71d form openings. Thereby, the groove part 71a which uses the piece 71b as a bottom part and has the pieces 71c and 71d as a side wall is formed in the inner side in the finding direction (see FIG. 13B).

  The downspout 72 is a downspout that functions as a summon spear in this embodiment as will be described later. The vertical rod 72 has a hollow portion 72b having a rectangular hollow shape in the cross section shown in FIG. Of the inner side surface of the hollow portion 72b in the direction of finding, pieces 72c and 72d extend inward in the direction of finding from both end portions in the prospective direction. As a result, a groove portion 72a is formed on the inner side in the finding direction, with one piece of the hollow portion 72b as a bottom portion and the pieces 72c and 72d as side walls.

  The upper horizontal rod 73 has a piece 73b extending in the prospective direction in the cross section shown in FIG. Furthermore, pieces 73c and 73d extending in the direction of finding are provided at both ends of the prospective direction of the piece 73b. At both ends in the direction of finding the pieces 73c and 73d, the portions sandwiched between the pieces 73c and 73d form openings. As a result, a groove 73a is formed on the inner side in the finding direction, with the piece 73b as a bottom and the pieces 73c and 73d as side walls.

  The lower horizontal rod 74 has a piece 74b extending in the prospective direction in the cross section shown in FIG. Furthermore, pieces 74c and 74d extending in the direction of finding are provided at both ends of the prospective direction of the piece 74b. At both ends in the direction of finding the pieces 74c and 74d, the portions sandwiched by the pieces 74c and 74d form openings. As a result, a groove 74a having the piece 74b as a bottom and the pieces 74c and 74d as side walls is formed on the inner side in the finding direction.

The shoji 60 provided with the above-described constituent members is formed by combining the constituent members as follows, for example.
That is, as can be seen from FIGS. 11 to 13, the plate glass 62, 63, the end of the gap between the plate glasses 62, 63, and the inter-panel sealing material 65 are inserted into the U-shaped inner side of the glazing channel 66 and surrounded. Arranged to be. At this time, the protrusion 66g of the glazing channel 66 is provided to be included inside the inter-panel seal member 65. As a result, the glazing channel 66 is fixed to the glass plates 62 and 63 via the inter-panel sealing material 65. Further, the fixing portion 66h provided at the tip of the protruding portion 66g makes the fixing more reliable and strong. At this time, at least a part of the bottom piece 66 a may also be bonded to the inter-panel sealing material 65. Thereby, it will be fixed more strongly.

  The seal portion 66c and the fin-like portions 66d and 66e provided on the standing piece 66b come into contact with the surfaces of the plate glasses 62 and 63 to improve watertightness and airtightness. Moreover, the water which infiltrated between the plate glass 62 and 63 and the standing piece 66b can be discharged | emitted by the hole 66f provided in the standing piece 66b. Specifically, when attached to a building, the hole of the glazing channel arranged in the upper part functions as an outside air introduction hole, and the hole of the glazing channel arranged in the lower part functions as a drainage hole.

  On the other hand, the reinforcing members 68 are disposed in the groove portions 71a, 72a, 73a, 74a formed in the vertical rods 71, 72, the upper horizontal rod 73, and the lower horizontal rod 74. At this time, each piece constituting the reinforcing member 68 is arranged along the inner surfaces of the groove portions 71a, 72a, 73a, 74a. A heating expansion body 67 is disposed along one piece of the reinforcing member 68. And it arrange | positions so that the edge part of the glazing channel 66 and the plate glass 62 and 63 which were integrated inside the groove part 71a, 72a, 73a, 74a of each ridge | pane may be inserted.

  Here, the glazing channel 66 can be fixed as follows, for example. That is, the spacers 64 are arranged so as to be sandwiched between the two glass sheets 62 and 63, and the space that is surrounded by the glass sheets 62 and 63 and the spacers 64 is filled with a material that becomes the inter-panel sealing material 65. Next, the glazing channel 66 is attached to the end portions of the glass sheets 62 and 63 while the filled inter-panel sealant 65 has fluidity. At this time, the protrusion 66 g of the glazing channel 66 is inserted into the inter-panel seal member 65. Thereafter, the glazing channel 66 is fixed to the ends of the glass plates 62 and 63 by the inter-panel sealant 65 being hardened.

  According to such a shoji 60, as in the first embodiment, the heating expansion body 67 that functions as a sealing means when the shoji 60 is heated by a fire or the like expands by the heat of the fire or the like. The flammable gas that has entered between the plate glass 62 and the plate glass 63 and has been generated from the inter-panel sealing material 65 can be sealed and confined between the plate glasses 62 and 63. Therefore, it is possible to prevent the combustible gas from flowing out and igniting. Further, when the reinforcing member 68 is provided as in the present embodiment, even when the glazing channel 66 disappears, at least one of the plate glasses 62 and 63 can be more reliably held in the housing 70. In addition to this, if a glass-containing glass or heat-resistant tempered glass is applied to at least one of the plate glasses 62 and 63, the plate glasses 62 and 63 are further reliably held in the housing 70.

  Moreover, according to the multilayer glass panel 61, when this is fitted to the housing 70 and it is used as the shoji 60, it can be made more watertight and airtight than before. That is, conventionally, when the door is opened and closed or the pressure difference between the inside and outside of the door is deformed, the watertight and airtightness between the glazing channel and the plate glass may be problematic. However, in the multi-layer glass panel 61, the glazing channel 66 is firmly fixed to the glass plates 62 and 63 via the inter-panel sealing material 65. Therefore, this fixing improves the strength of the entire shoji and the deformation and the above. The problem of watertightness and airtightness can be solved. Therefore, even when there is such a problem, this can be solved.

Here, modified examples 1 to 4, which are other examples of fixing the glazing channel, will be described. FIG. 14A shows a cross-sectional view of the glazing channel 166 used in the first modification, and FIG. 14B shows a cross-sectional view of the glazing channel 266 used in the second modification. The other parts are the same as those of the multi-layer glass panel 61 described above, and thus the description thereof is omitted.
The glazing channel 166 according to the first modification is different from the glazing channel 66 in that the protrusion has two protrusions, a first protrusion 166a and a second protrusion 166b. As a result, the fixing between the inter-panel seal member 65 and the glazing channel 166 is further strengthened.
The glazing channel 266 according to the modification 2 is characterized in that the protruding portion 266c is provided separately. The bottom piece 266a of the glazing channel 266 is provided with a slit 266b, and the protruding portion 266c can protrude inside the U-shape so as to penetrate therethrough. According to this, it is possible to attach a necessary portion without excess or deficiency to a portion requiring strength.

FIG. 15 is a diagram for explaining the third modification. FIG. 15A is a view focusing on the vicinity of the end of the multilayer glass panel in Modification 3, and FIG. 15B is an exploded view thereof. In this example, the glazing channel 366 does not have a protruding portion, and is characterized in that an engagement protrusion 366a is provided on the outer surfaces of the glass sheets 62 and 63 (the surfaces of the glass sheets that do not face each other). As can be seen from FIG. 15A, the fin-like portions 66d and 66e of the glazing channel 366 can be hooked on the engaging protrusion 366a. According to this, the glazing channel 366 can be mechanically coupled to the glass plates 62 and 63.
Such an engagement protrusion may be a protrusion formed on the surface of the glass plate. For example, the protrusion may be bonded to the surface of the glass plate with a double-sided tape, an adhesive, or the like. Moreover, the engaging protrusion does not need to be provided continuously along the surface of the glass plate, and may be provided intermittently.
In the case of such a connection, since the hole 66f is provided in the standing piece 66b as shown in FIG. 15, a gap can be provided between the bottom 66a and the inter-panel seal member 65. Can also be provided on the bottom plate 66a.

Next, Modification 4 will be described. FIG. 16 shows a diagram for explanation. FIG. 16A is a view focusing on the vicinity of the end portion of the multilayer glass panel in Modification 4, and FIG. 16B is an exploded view thereof. The modification 4 differs from the multilayer glass panel 61 in that an outer peripheral tape 466 is disposed between the end faces of the plate glasses 62 and 63 and the glazing channel 66.
The outer peripheral tape 466 is a belt-like shape wound along the circumferential direction of the outer periphery of the plate glass 62, 63 so as to cover the end surfaces of the plate glass 62, 63 and the end surface of the inter-panel seal member 65 from above the inter-panel seal member 65. Tape material. Accordingly, as will be described later, when the glazing channel 66 is attached to the fluid inter-panel seal member 65, the glazing channel 66 can be prevented from being damaged by the inter-panel seal member 65.

As will be described later, the outer peripheral tape 466 has a slit 466a through which the protrusion 66g of the glazing channel 66 passes. The material of the outer peripheral tape 466 is not particularly limited, but is preferably an adhesive tape having polyester, polypropylene, vinyl chloride, cellophane tape or aluminum as a base material and an adhesive on one side.
The outer peripheral tape 466 is not necessarily disposed over the entire end surface of the multilayer glass panel, and may be disposed so as to include at least two corners among the four corners existing in the circumferential direction. This is based on the fact that the corner portion is most likely to cause contamination of the glazing channel by the sealing material.

  Therefore, the end surfaces of the plate glasses 62 and 63 and the inter-panel seal member 65 are covered with the outer peripheral tape 466 as can be seen from FIG. Further, the end portions of the plate glasses 62 and 63 and the inter-panel seal member 65 are inserted and enclosed inside the U shape of the glazing channel 66 including the outer peripheral tape 466. At this time, the protruding portion 66 g of the glazing channel 66 is provided so as to penetrate the slit 466 a of the outer peripheral tape 466 and be included inside the inter-panel seal member 65. As a result, the glazing channel 66 is fixed to the glass plates 62 and 63 via the inter-panel sealing material 65. Further, the retaining portion 66h provided at the tip of the protruding portion 66g makes the fixing more reliable and strong.

  The slit 466a of the outer peripheral tape 466 is finally formed by any means. Means for that are not particularly limited. For example, before winding the outer peripheral tape 466, a slit-like cut is made by a cutter or the like, or a perforation means such as a perforated cut is provided. it can. Alternatively, after the outer peripheral tape 466 is wound around the end portions of the plate glasses 62 and 63, a slitting cut may be made on the outer peripheral tape 466 by a cutter or a perforation means such as a perforated cut may be provided. In addition, the outer peripheral tape may be made of a material that tears and penetrates the outer peripheral tape by pressing the protruding portion of the glazing channel against the outer peripheral tape.

  Next, the opening part apparatus 80 provided with the shoji 60 is demonstrated. FIG. 17 is a horizontal sectional view of the opening device 80, and FIG. 18 is a vertical sectional view of the opening device 80. In FIG. 17, the upper side of the paper indicates the outdoor side and the lower side of the paper indicates the indoor side. In FIG. 18, the left side of the drawing represents the outdoor side, and the right side of the drawing represents the indoor side. In the present embodiment, the opening device 80 is a so-called sliding door sash window.

  The opening device 80 includes a frame 81 arranged along the edges of the four sides of the building opening, and two shojis 60 that are provided inside the frame 81 and open and close in a sliding door manner.

  The frame body 81 is disposed horizontally on the upper and lower sides of the vertical frames 82 and 83 erected in the vertical direction with a predetermined interval on the left and right, and between the ends of the vertical frames 82 and 83. The upper horizontal frame 84 and the lower horizontal frame 85, which are long members, are combined in a frame shape.

  The vertical frame 82 is a frame material that constitutes one of the two vertical frames of the frame body 81, and the side on which the vertical rod 71 of the shoji 60 that is the outdoor side is disposed in a posture in which the opening device 80 is closed. It is a vertical frame. FIG. 19A shows a view of the vertical frame 82 in FIG. 17, and FIG. 19B shows an exploded cross-sectional view of the vertical frame 82.

The vertical frame 82 includes a vertical frame main body 86 and cover members 87 and 88 as cover portions, and the cover member 88 is fixed to the vertical frame main body 86 by fixing means 89.
The vertical frame main body 82 has a piece 86a extending in the prospective direction in the cross section shown in FIGS. Pieces 86b and 86e extending in the direction of finding are provided at the indoor side end and the outdoor side end of the piece 86a, respectively. In addition, a piece 86c and a piece 86d are erected on the inner surface in the direction of finding of the piece 86a (see FIG. 19). Here, the tip of the piece 86c is formed to be bent toward the outside in the prospective direction. Further, the piece 86d is provided at a position where it is inserted into the inner side of the vertical gutter 71 in the closed posture of the shoji 60.
Further, a piece 86f is erected on the outer surface in the direction of finding of the piece 86a. The vertical frame 82 is attached to the building by fixing the piece 86f to the building frame.

  The material of the vertical frame body 86 is not particularly limited, but a metal is preferable from the viewpoint of strength and productivity, and aluminum is most preferably used for a normal sash. In the present embodiment, the vertical frame main body 86 is integrally formed. However, the present invention is not limited to this, and several metal members may be combined and integrated. Moreover, it is good also as what is called a bridge | bridging structure which divides a vertical frame main body into an outdoor side member and an indoor side member, and connects this with a heat insulating member. Thereby, heat insulation can be improved further.

  The cover member 87 is a long member disposed along the longitudinal direction of the vertical frame main body 86. The cover member 87 has a rectangular portion 87a that is substantially rectangular and hollow in the cross section shown in FIGS. 17 and 19 (see FIG. 19). In the prospective direction outdoor side which is one corner of the rectangular portion 87a, the corner on the outer side in the finding direction is notched, and a U-shaped portion 87b is formed here. The U-shaped portion 87b opens to the outside in the direction of finding. The opening portion is provided with protrusions 87c and 87d that are opposed to each other with the position slightly shifted so as to narrow the opening.

  In addition, a piece 87e extends from the corner at the diagonal position with respect to the U-shaped portion 87b among the corners of the rectangular portion 87a toward the inside of the prospective direction. From the tip of the piece 87e, a piece 87f extending toward the outside in the finding direction is provided.

  The cover member 88 is also a long member disposed along the longitudinal direction of the vertical frame main body 86 (the rear side / front side in FIGS. 17 and 19). In the cross section shown in FIGS. 17 and 19, the cover member 88 is formed into a crank shape by a piece 88 a extending in the direction of finding and pieces 88 b and 88 c extending in the prospective direction from both ends thereof.

  Here, in this embodiment, the cover member 87 and the cover member 88 are engaged by the piece 87f and the piece 88a. The cover member does not necessarily need to be integrated by engaging two members, and may be formed by one member. In the present embodiment, since the cover member 88 can be used as it is in the vertical frame 83 which is the other vertical frame, such a configuration is used from the viewpoint of suppressing the types of components.

  The cover members 87 and 88 are preferably made of a material having low thermal conductivity. Thereby, heat insulation can be improved. The lower the thermal conductivity, the higher the heat insulating property, but the thermal conductivity is preferably 10 W / m · K or less. Therefore, specifically, it is preferable to form the cover member using a resin material. This is because the thermal conductivity is low and the moldability is also excellent. For example, PVC can be used, and the thermal conductivity is about 0.17 W / m · K.

Such vertical frame main body 86 and cover members 87 and 88 are combined as follows. That is, on the indoor side in the prospective direction of the vertical frame main body 86, the piece 88a is overlapped with the piece 88b of the cover member 88 and the piece 86b is overlapped with the piece 88a of the cover member 88. The pieces 88b and 86a are fixed by the fixing member 89. In this embodiment, the tip of the piece 86b is more securely fixed by engaging the piece 88a.
The cover member 87 is arranged so that the piece 86c of the vertical frame body 86 is inserted inside the U-shaped portion 87b. As described above, the piece 86c is formed in an L shape. On the other hand, the opening of the U-shaped portion 87b is provided with protrusions 87c and 87d so as to narrow the opening. As a result, the cover member 87 is difficult to be removed from the vertical frame body 86, and the cover member 87 can also be rotated around this. And the said rotation is made and the piece 87f of the cover member 87 and the piece 88a of the cover member 88 are engaged.
Thereby, the cover members 87 and 88 can cover a part of the interior side of the vertical frame body 86 on the indoor side in the expected direction.

  The size of the cover members 87 and 88 indicated by E in FIG. 19B can be determined by the relationship with other members to be described later. Therefore, these will be described in detail after describing other members.

  Although the said aspect was demonstrated as one preferable embodiment here, it is not limited to this. For example, the vertical frame and the cover part may be integrally formed of metal or resin, the outdoor half is made of a metal frame, and the indoor half is made of resin and the frame and the cover part are integrally formed. These may be connected in an indoor / outdoor direction.

  Subsequently, the frame body 81 will be described. The vertical frame 83 is a frame material that constitutes one of the two vertical frames of the frame 81, and the vertical rod 71 of the shoji 60 that is disposed indoors is disposed in a posture in which the opening device 80 is closed. It is a vertical frame on the side. This will be described with reference to FIG.

The vertical frame 83 includes a vertical frame main body 90 and a cover member 91 as a cover portion, and the cover member 91 is fixed to the vertical frame main body 90 by fixing means 92.
The vertical frame main body 90 has a piece 90a extending in the prospective direction in the cross section shown in FIG. Pieces 90b and 90e extending in the direction of finding are provided at the indoor side end and the outdoor side end of the piece 90a, respectively. Further, a piece 90d is erected on the inner side surface in the direction of finding the piece 90a. Here, the piece 90d is provided at a position to be inserted inside the downpipe 71 in a closing posture of the shoji 60 disposed on the indoor side. Further, a piece 90f is erected on the outer surface in the direction of finding of the piece 90a. The vertical frame 83 is attached to the building by fixing the piece 90f to the building frame.

  The material of the vertical frame main body 90 is not particularly limited, but is preferably a metal from the viewpoint of strength and productivity, and most preferably aluminum used for a normal sash. In the present embodiment, the vertical frame main body 90 is integrally formed. However, the present invention is not limited to this, and several metal members may be combined and integrated. Moreover, it is good also as what is called a bridge | bridging structure which divides a vertical frame main body into an outdoor side member and an indoor side member, and connects this with a heat insulating member. Thereby, heat insulation can be improved further.

  The cover member 91 has the same shape as the cover member 88. That is, the cover member 91 is a long member disposed along the longitudinal direction of the vertical frame main body 90. In the cross section shown in FIG. 17, the cover member 91 is formed in a crank shape by a piece 91 a extending in the finding direction and pieces 91 b and 91 c extending in the prospective direction from both ends thereof.

  The cover member 91 is preferably made of a material having low thermal conductivity. Thereby, heat insulation can be improved. The lower the thermal conductivity, the higher the heat insulating property, but the thermal conductivity is preferably 10 W / m · K or less. For that purpose, specifically, it is preferable to form the cover member using a resin material. This is because the thermal conductivity is low and the moldability is also excellent. For example, PVC can be used, and the thermal conductivity is about 0.17 W / m · K.

Such a vertical frame main body 90 and the cover member 91 are combined as follows.

  Since the shoji 60 has been described above, the description thereof is omitted here. However, as for the two shoji 60 provided in the opening device 80, the cross-sectional shape of the heel differs between the shoji 60 arranged on the indoor side and the shoji 60 arranged on the outdoor side. In the present embodiment, the vertical gutter 71 functions as a doorside gutter and the vertical gutter 72 functions as a summon gutter.

  The opening device 80 is formed by arranging the two shoji 60 in the frame of the frame 81 in a sliding door manner. That is, the upper horizontal frame 73 of the shoji 60 is guided by the pieces 93 c and 93 d of the upper horizontal frame 84, and the door wheel provided on the lower horizontal frame 74 of the shoji 60 is placed on the pieces 95 d and 95 e of the lower horizontal frame 95. By being guided, the shoji 60 can be opened and closed in a sliding door manner.

The opening device 80 described above has the following features in addition to the functions described above. This will be described with reference to FIGS.
The position indicated by B in FIGS. 17 and 19 is compared with the position indicated by A in the closed position of the opening device 80. The position indicated by B is a position where the inner end portion in the finding direction of the vertical rod 71 is arranged in the posture in which the shoji 60 is closed. On the other hand, the position indicated by A is the position where the inner ends of the cover members 88 and 91 are located in the vertical frames 82 and 83.

  In the opening device 80, the position indicated by B is arranged on the outer side in the finding direction than the position indicated by A. Accordingly, the vertical rods 82 and 83 are concealed from the indoor front view in the closed posture of the opening device 80. Here, the position of B is located outside the position of A in the direction of finding, but this is flush (the same position), or the position of B is slightly located in the direction of finding than the position of A if slightly. You may arrange | position inside. Specifically, it is preferable that 90% or more of the size in the direction in which the door toe is found is concealed.

  In the opening device 80, as described above, the ridge is formed thin. Therefore, heat transfer through the ridge can be suppressed. If the multilayer glass panel 61 is applied, it is possible to make the wrinkles thinner. That is, conventionally, there is a problem that the ridge cannot be thinned because the ridge is deformed by opening / closing of the ridge or a pressure difference between the inside and outside of the room, causing a problem of watertightness between the glazing channel and the plate glass. Even when there is such a problem, if the multi-layer glass panel 61 is used, the glazing channel 66 is firmly fixed to the plate glasses 62 and 63 through the inter-panel seal member 65, and so this fixing is a shoji. The strength with respect to the whole can be improved, and the above-described deformation and the problem of watertightness and airtightness due to this can be solved. And even if it is a form which concerns, drainage is also possible by the hole 66f provided in the standing part 66b of the glazing channel 66. FIG.

  In addition, the vertical rod 71 in which the heat transfer is thus suppressed is hidden from the room view by the cover member. Thereby, heat transfer between the bag and the room can be suppressed, and the heat insulation performance can be further improved. That is, if there is a further problem of improving heat insulation, this can be solved.

With this configuration, both the frame and the ridge can be used without using a conventional bridge material method (a method in which the frame or ridge is divided into an indoor member and an outdoor member, and these are connected by a resin or the like). It becomes possible to improve the heat insulation performance. That is, the heat insulation performance can be improved with a simple configuration. However, this does not prevent the application of the bridge method, and a bridge structure may be used. This is because further improvement in heat insulation can be expected.
With this configuration, when a conventional opening device is installed in an opening of a certain size, H-3 grade (JIS A 4706, JIS A 4702, thermal flow resistance 0.287 m 2 · K / W or more) Even if the heat insulation performance cannot be obtained, according to the opening device 100, it becomes possible to obtain the heat insulation performance of H-3 grade.

  Moreover, the above-mentioned multi-layer glass panel 61 can form a wrinkle thinly, and since this wrinkle is concealed indoors, the appearance is excellent. Here, since the cover members 88 and 91 only need to be formed so as to hide the thin ridges, the dimension indicated by E in FIG.
