[0010] (First embodiment) A first embodiment of the present disclosure will be described below with reference to the drawings. The surface material holding member of this embodiment is a glazing channel 5 (sometimes simply referred to as "glazing channel 5"). The glazing channel 5 holds the outer peripheral edge portion 41a of the surface material 41 of the fitting 1 in the fitting 1.

[0011] As shown in Figures 1 to 3, the fitting 1 is installed in an opening 100a of a building 100. The fitting 1 is, for example, a sliding window, and comprises a frame body 2 with a frame on all four sides and multiple (specifically, two) shoji screens 3. The frame body 2 is made of a shaped material made of aluminum, an aluminum-resin composite, or resin. The multiple shoji screens are slidably housed within the frame body 2.

[0012] In this specification, "up-down direction" means the direction from top to bottom. "Indoor-outdoor direction" means the direction connecting the outdoor side and the indoor side along the horizontal direction. The indoor side direction is also the thickness direction of the surface material 41 arranged in the door / window 1. "View direction" means the direction in which the surface of the surface material 41 in the door / window 1 extends. "Left-right direction" is the horizontal direction in the view direction, and means the left-right direction when the surface material 41 is viewed from the indoor side.

[0013] The frame body 2 has an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23.

[0014] The upper frame 21 is a long member extending in the left-right direction at the upper edge of the opening 100a. The lower frame 22 is a long member extending in the left-right direction at the lower edge of the opening 100a. Each vertical frame 23 is a long member extending in the up-down direction at the left or right edge of the opening 100a.

[0015] A horizontal piece 221 extending toward the outside of the room is provided on the indoor-side portion of the lower frame 22. The horizontal piece 221 is shaped like a plate with a surface that extends in the indoor-outdoor and left-right directions. An airtight material 222 is provided on the outdoor end of the horizontal piece 221. The airtight material 222 faces the indoor-side surface of the bottom frame 33 (described below) of the outdoor-side shoji screen 3, and more specifically, is in contact with or close to it. The airtight material 222 is made of an elastic material such as resin. This improves the airtightness between the outdoor-side shoji screen 3 and the lower frame 22.

[0016] The shoji screen 3 has a frame 31 and a surface material 41.

[0017] The frame 31 is a member that forms the outer edge of the shoji screen 3. The frame 31 is formed in a rectangular frame shape. The frame 31 is made of aluminum, an aluminum-resin composite, or a resin shaped material. The frame 31 has an upper frame 32, a lower frame 33, and a pair of vertical frames 34.

[0018] The upper frame 32 is a long member extending in the left-right direction that constitutes the upper edge of the shoji screen 3. The lower frame 33 is a long member extending in the left-right direction that constitutes the lower edge of the shoji screen 3. Each vertical frame 34 is a long member extending in the up-down direction that constitutes the left or right edge of the shoji screen 3, respectively.

[0019] Additionally, a groove 36 is provided on the inner peripheral surface of the frame 31. The groove 36 is the portion into which the face material 41 is inserted. The groove 36 extends over the entire circumferential area of ​​the frame 31. The groove 36 opens toward the center of the shoji screen 3 in the vertical and horizontal directions. The groove 36 has a U-shape in cross section. The groove 36 has an exterior engagement portion 37 provided on the exterior side of the inner peripheral surface of the groove 36, and an interior engagement portion 38 provided on the interior side of the inner peripheral surface of the groove 36.

[0020] As will be described in detail later, the outdoor engaging portion 37 and the indoor engaging portion 38 each engage with the grill channel 5. The outdoor engaging portion 37 has, for example, a convex shape that is convex toward the indoor side. The indoor engaging portion 38 has, for example, a convex shape that is convex toward the outdoor side.

[0021] The face material 41 is a rectangular plate material held inside the frame 31. The plate surface of the face material 41 extends in a direction perpendicular to the indoor-outdoor direction. The face material 41 is, for example, a glass panel. The outer peripheral edge of the face material 41 is referred to as the "outer peripheral edge 41a," and the end face of the face material 41 in the outer peripheral edge 41a is referred to as the "end face 41aa." The frame 31 corresponds to a frame member.

[0022] The grate channel 5 is disposed between the face material 41 and the frame 31 provided on the outer peripheral edge of the face material 41, and holds the face material 41. The configuration of the grate channel 5 will be described below using the grate channel 5 disposed between the face material 41 and the lower frame 33 as an example.

[0023] The configuration of the grate channel 5 arranged between the face material 41 and the upper frame 32 is a configuration obtained by inverting the configuration of the grate channel 5 arranged between the face material 41 and the lower frame 33, and the configuration of the grate channel 5 arranged between the face material 41 and the vertical frame 34 is a configuration obtained by rotating the configuration of the grate channel 5 arranged between the face material 41 and the lower frame 33 by 90 degrees. Therefore, detailed explanations of the configuration of the grate channel 5 arranged between the face material 41 and the lower frame 33 and the configuration of the grate channel 5 arranged between the face material 41 and the vertical frame 34 will be omitted.

[0024] As shown in FIG. 4, the outer peripheral edge 41a of the face material 41 is inserted into the grate channel 5. The grate channel 5 extends along the outer peripheral edge 41a of the face material 41. The cross-sectional shape of the grate channel 5 in a direction perpendicular to the longitudinal direction of the grate channel 5 is generally U-shaped overall. The shape of the grate channel 5 is symmetrical in the indoor-outdoor direction, for example. The grate channel 5 includes an outdoor side wall portion 52A extending along the outdoor surface of the face material 41, an indoor side wall portion 52B extending along the outdoor surface of the face material 41, and a bottom portion 51 extending along the end face 41aa of the face material 41 and connecting the outdoor side wall portion 52A and the indoor side wall portion 52B.

[0025] The outdoor side wall portion 52A has a plurality of (specifically, three) outdoor protrusions 53A that protrude toward the face material 41, and an outdoor engaged portion 55A that engages with the outdoor engaging portion 37 of the groove portion .

[0026] Each outdoor protrusion 53A is provided, for example, on the upper part of the outdoor side wall portion 52A. Each outdoor protrusion 53A is provided, for example, at intervals in the vertical direction. Each outdoor protrusion 53A is, for example, fin-shaped. At least one of the outdoor protrusions 53A is in contact with the face material 41; for example, the uppermost and lowermost of the three outdoor protrusions 53A are in contact with the face material 41, while the central outdoor protrusion 53A is spaced apart from the face material. In this way, it is not necessary for all outdoor protrusions 53A to be in contact with the face material 41.

[0027] The outdoor engaged portion 55A is provided, for example, on the upper part of the outdoor side wall portion 52A. The outdoor engaged portion 55A is aligned, for example, with the outdoor protrusion portion 53A in the indoor-outdoor direction. The outdoor engaged portion 55A is formed, for example, such that the outdoor surface of the outdoor side wall portion 52A is recessed toward the face material 41. The outdoor side wall portion 52A contacts the lower frame 33 at the outdoor engaged portion 55A.

[0028] The indoor side wall portion 52B has a plurality of (specifically, three) indoor side protrusions 53B that protrude toward the face material 41, and an indoor side engaged portion 55B that engages with the indoor side engaging portion of the groove portion .

[0029] Each indoor protrusion 53B is provided, for example, on the upper part of the indoor side wall portion 52B. Each indoor protrusion 53B is provided at intervals in the vertical direction. Each indoor protrusion 53B is provided, for example, at intervals in the vertical direction. Each indoor protrusion 53B is fin-shaped, for example. At least one of the indoor protrusions 53B is in contact with the face material 41, and for example, the uppermost indoor protrusion 53B and the lowermost indoor protrusion 53B of the three indoor protrusions 53B abut against the face material 41, and the central indoor protrusion 53B is spaced apart from the face material. In this way, it is not necessary for all indoor protrusions 53B to abut against the face material 41.

[0030] The outdoor protrusion 53A and the indoor protrusion 53B are sometimes collectively referred to as "protrusion 53." Protrusion 53 in contact with face material 41 is elastically deformed. However, in each drawing, protrusion 53 is shown in an undeformed state for convenience.

[0031] The indoor side engaged portion 55B is provided, for example, on the upper part of the indoor side wall portion 52B. The indoor side engaged portion 55B is, for example, aligned with the indoor side protrusion portion 53B in the indoor-outdoor direction. The indoor side engaged portion 55B is formed, for example, such that the indoor side surface of the indoor side wall portion 52B is recessed toward the face material 41. The indoor side wall portion 52B contacts the lower frame 33 at the indoor side engaged portion 55B.

[0032] Here, the grease channel 5 comprises a sintered portion 61 containing a sintering agent and a non-sintered portion 62 in which the content of the sintering agent is less than the content of the sintering agent in the sintered portion 61. The non-sintered portion 62 is in contact with at least one of the frame 31 (lower frame 33) and the face material 41.

[0033] The sintering agent sinters the glass channel 5 hard when it is exposed to a flame and combusted, and maintains the shape of the glass channel 5 at the time of molding even after combustion. The sintering agent sinters and solidifies at the temperature during combustion (500°C or higher). The sintering agent is, for example, at least one substance selected from the group consisting of glass, sodium silicate, silica, china clay, iron oxide, and ferrite.

[0034] The sintered portion 61 contains a base material that is at least one of rubber and resin.

[0035] The non-sintered portion 62 either does not contain a sintering agent or contains a sintering agent at a content lower than the content of sintering agent in the sintered portion 61. It is preferable that the non-sintered portion 62 does not contain a sintering agent. The non-sintered portion 62 contains a substrate of the glass channel 5, which is at least one of rubber and resin.

[0036] The portion of the gray channel 5 located outside the surface material 41 and the portion of the gray channel 5 located inside the surface material 41 have a non-sintered portion 62 and a sintered portion 61, respectively.

[0037] In the gray channel 5, each protrusion 53 is formed by a non-sintered portion 62, and the portion of the outdoor side wall portion 52A excluding the outdoor protrusion portion 53A, the portion of the indoor side wall portion 52B excluding the indoor protrusion portion 53B, and the bottom 51 are each formed by a sintered portion 61.

[0038] The non-sintered portion 62 is in contact with at least one of the lower frame 33 and the face material 41, and more specifically, it is in contact with the face material 41. For example, the non-sintered portion 62 of the portion of the gray channel 5 that is on the outdoor side of the face material 41 is in contact with the outdoor side surface of the face material 41. The portion of the gray channel 5 that is on the indoor side of the face material 41 is in contact with the indoor side surface of the face material.

[0039] At least a portion of the portion of the gray channel 5 that is in contact with the surface material 41 is a non-sintered portion 62, and more specifically, the entire portion of the gray channel 5 that is in contact with the surface material 41 is a non-sintered portion 62.

[0040] The sintered portion 61 is arranged, for example, between the non-sintered portion 62 and the bottom frame 33. On the outdoor side of the face material 41, the sintered portion 61 is arranged between the non-sintered portion 62 and the bottom frame 33. The outdoor side surface of the face material 41, the non-sintered portion 62, the sintered portion 61, and the bottom frame 33 are lined up in this order from the indoor side toward the outdoor side. On the indoor side of the face material 41, the sintered portion 61 is arranged between the non-sintered portion 62 and the bottom frame 33. The indoor side surface of the face material 41, the non-sintered portion 62, the sintered portion 61, and the bottom frame 33 are lined up in this order from the outdoor side toward the indoor side.

[0041] The sintered portion 61 is provided, for example, continuously from the outdoor side wall portion 52A through the bottom portion 51 to the indoor side wall portion 52B. The sintered portion 61 includes, for example, the entire surface of the grate channel 5 that faces the lower frame 33. The non-sintered portion 62 is not in contact with the lower frame 33.

[0042] The substrate contained in the non-sintered portion 62 and the substrate contained in the sintered portion 61 are, for example, chloroprene rubber, ethylene propylene rubber, ethylene propylene diene rubber, silicone, silicone rubber, polyvinyl chloride, ABS resin, AES resin, thermoplastic elastomer, etc. At least one of the substrate contained in the non-sintered portion 62 and the substrate contained in the sintered portion 61 is preferably chloroprene rubber, and it is more preferable that both the substrate contained in the non-sintered portion 62 and the substrate contained in the sintered portion 61 are chloroprene rubber.

[0043] The sintered portion 61 preferably contains a flame retardant. Examples of the flame retardant include antimony trioxide, zinc formate, aluminum hydroxide, and halogen compounds. The flame retardant is preferably antimony trioxide.

[0044] When the substrate is rubber, the sintered portion 61 preferably contains carbon black, a vulcanizing agent, and a softener together with the substrate and sintering agent. When the substrate is resin, the sintered portion 61 preferably contains a pigment plasticizer together with the substrate and sintering agent.

[0045] The gray channel 5 is manufactured by, for example, extrusion molding, more specifically, two-color molding. However, the manufacturing method of the gray channel 5 is not limited to this, and for example, the gray channel 5 may be manufactured by separately manufacturing the non-sintered portion 62 and the sintered portion 61, and then bonding the obtained non-sintered portion 62 and sintered portion 61 together. However, it is preferable to manufacture the gray channel 5 by two-color molding because this results in lower manufacturing costs.

[0046] According to the gray channel 5 of this embodiment, the following effects are achieved.

[0047] The grease channel 5 of this embodiment comprises a sintered portion 61 containing a sintering agent and a non-sintered portion 62 in which the sintering agent content is less than the sintering agent content in the sintered portion 61, and the non-sintered portion 62 is in contact with at least one of the frame 31 and the face material 41.

[0048] With this configuration, the sintered portion 61 can be suitably sintered in the event of a fire. This makes it easier to maintain the shape of the glass channel 5 in the event of a fire, thereby improving the flame-proofing properties of the fitting 1.

[0049] Furthermore, the content of sintering agent in the non-sintered portion 62 is less than the content of sintering agent in the sintered portion 61. Reducing the content of sintering agent in an object can change the elasticity, viscosity, etc. of the object containing the sintering agent, thereby improving vibration damping. Therefore, the non-sintered portion 62 has better vibration damping properties than the sintered portion 61. The non-sintered portion 62 can also effectively damp sound vibrations. Therefore, by having the non-sintered portion 62 in contact with either the face plate 41 or the frame 31, the non-sintered portion 62 can suppress the transmission of sound vibrations between the face plate 41 and the lower frame 33. This can improve the sound insulation of the fitting 1.

[0050] Therefore, it is possible to provide a glass channel 5 that can improve sound insulation while ensuring flame insulation.

[0051] According to this embodiment, the non-sintered portion 62 is in contact with the face material 41 .

[0052] Since non-sintered materials are more susceptible to elastic deformation than sintered materials, the non-sintered portion 62 is more susceptible to elastic deformation than the sintered portion 61. Therefore, this configuration ensures ease of installation of the gray channel 5 to the surface material 41 while allowing the gray channel 5 and the surface material 41 to be more appropriately attached to each other. This improves sound insulation. Furthermore, the airtightness and heat insulation of the fitting 1 can also be improved.

[0053] According to this embodiment, the sintered portion 61 is disposed between the non-sintered portion 62 and the frame 31 .

[0054] With this configuration, even if the non-sintered portion 62 disappears, the sintered portion 61 can remain between the face material 41 and the frame 31. This makes it possible to prevent the face material 41 from falling off in the event of a fire, thereby improving flame-blocking properties.

[0055] According to this embodiment, the portion of the gre channel 5 on the outdoor side of the face material 41 is formed by the non-sintered portion 62 and the sintered portion 61, and the portion of the gre channel 5 on the indoor side of the face material 41 is formed by the non-sintered portion 62 and the sintered portion 61.

[0056] This configuration makes it possible to improve the flame and sound insulation properties on both sides of the face material 41 in the indoor / outdoor direction, thereby more suitably achieving the desired effects.

[0057] According to this embodiment, the sintered portion 61 is provided continuously from the outdoor side wall portion 52A through the bottom portion 51 to the indoor side wall portion 52B.

[0058] With this configuration, even if the non-sintered portion 62 burns, the outer peripheral edge portion 41a of the face material 41 can be covered by the sintered portion 61. This makes it possible to prevent the face material 41 from falling off in the event of a fire, thereby improving flame-blocking properties.

[0059] Furthermore, it is more preferable that the sintered portion 61 includes the entire surface of the gray channel 5 that faces the lower frame 33 .

[0060] According to this configuration, even if the non-sintered portion 62 burns, the outer peripheral edge portion 41a of the face material 41 can be more reliably covered with the sintered portion 61.

[0061] According to this embodiment, at least one of the substrate contained in the sintered portion 61 and the substrate contained in the non-sintered portion 62 is preferably made of chloroprene rubber.

[0062] Chloroprene rubber has superior durability compared to, for example, vinyl chloride. Therefore, this configuration can improve the durability of the gray channel 5. Furthermore, the gray channel 5 can be suitably applied to buildings such as luxury homes that are expected to be used for a long period of time.

[0063] According to this embodiment, the building fixture 1 comprises a surface material 41, a frame 31 provided on the outer peripheral edge of the surface material 41, and a glass channel 5 arranged between the surface material 41 and the frame 31 to hold the surface material.

[0064] According to this configuration, it is possible to provide a fitting 1 that can improve sound insulation while ensuring flame insulation.

[0065] (Modification of the first embodiment) Next, first to sixth modified examples of the first embodiment will be described with reference to Figs. 5 to 10. In the first to sixth modified examples of the first embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and will not be described again. The shape of the grate channel 5 in each modified example of the first embodiment is the same as that of the grate channel 5 in the first embodiment. In each modified example of the first embodiment, the arrangement of the non-sintered portion 62 and the sintered portion 61 is different from that in the first embodiment.

[0066] As shown in Figure 5, in the first modified example of the first embodiment, in the gray channel 5, the upper part of the outdoor side wall portion 52A excluding the outdoor protrusion portion 53A and the upper part of the indoor side wall portion 52B excluding the indoor protrusion portion 53B are formed by non-sintered portions 62, and each protrusion portion 53 and the bottom portion 51 are both formed by sintered portions 61.

[0067] The portion of the gray channel 5 that is in contact with the face material 41 is formed by a sintered portion 61 over the entire area.

[0068] The surface of the outdoor engaged portion 55A and the surface of the indoor engaged portion 55B are each formed by a non-sintered portion 62. The non-sintered portion 62 is in contact with the bottom frame 33, and more specifically, is in contact with the outdoor engaging portion 37 and the indoor engaging portion 38, respectively. The contact between the non-sintered portion 62 and the bottom frame 33 allows vibrations of the surface material 41 to be damped before they are transmitted to the bottom frame 33.

[0069] In this way, each protrusion 53 does not necessarily have to be formed by the non-sintered portion 62. The non-sintered portion 62 does not necessarily have to be in contact with the face material 41, but only needs to be in contact with at least one of the face material 41 and the lower frame 33. The sintered portion 61 is not prevented from contacting the face material 41.

[0070] 6, in the second modified example of the first embodiment, each of the outdoor protrusions 53A is made of a non-sintered portion 62, and the entire portion of the outdoor protrusions 53A of the grate channel 5 is made of a sintered portion 61. Each of the indoor protrusions 53B is made of a sintered portion 61.

[0071] The portion of the gre channel 5 that comes into contact with the outdoor surface of the face material 41 is formed by a non-sintered portion 62. The portion of the gre channel 5 that comes into contact with the indoor surface of the face material 41 is formed by a sintered portion 61.

[0072] In this way, it is not necessary for both the surface of the glass channel 5 facing the outdoor side of the face material 41 and the portion in contact with the surface of the face material 41 facing the indoor side to be formed by the non-sintered portion 62 .

[0073] As shown in Fig. 7, the grate channel 5 of the third modified example of the first embodiment has a configuration in which the grate channel 5 of the second modified example of the first embodiment is inverted in the indoor / outdoor direction. Each indoor side protrusion 53B is formed of a non-sintered portion 62, and the portion of the grate channel 5 excluding each indoor side protrusion 53B is formed of a sintered portion 61. Each outdoor side protrusion 53A is formed of a non-sintered portion 62.

[0074] The portion of the gre channel 5 that comes into contact with the outdoor surface of the face material 41 is formed by a sintered portion 61. The portion of the gre channel 5 that comes into contact with the indoor surface of the face material 41 is formed by a non-sintered portion 62.

[0075] In this way, if only one of the portion of the gre channel 5 that contacts the outdoor surface of the face material 41 and the portion that contacts the indoor surface of the face material 41 is formed by the non-sintered portion 62, only the portion of the gre channel 5 that contacts the outdoor surface of the face material 41 may be formed by the non-sintered portion 62, or only the portion that contacts the indoor surface of the face material 41 may be formed by the non-sintered portion 62.

[0076] 8, in the grate channel 5 of the fourth modified example of the first embodiment, one of the indoor side protrusions 53B is formed of a non-sintered portion 62, and the other indoor side protrusions 53B are each formed of a sintered portion 61. The entire portion of the grate channel 5 excluding the indoor side protrusions 53B is formed of the sintered portion 61.

[0077] In this case, the portion of the gray channel 5 that comes into contact with the face material 41 is formed by the non-sintered portion 62.

[0078] In this way, the portion of the gray channel 5 that comes into contact with the indoor surface of the surface material 41 may include both a portion formed by the non-sintered portion 62 and a portion formed by the sintered portion 61.

[0079] 9, in the grate channel 5 of the fifth modified example of the first embodiment, all of the indoor protrusions 53B and the upper part of the indoor side wall 52B are formed of the non-sintered part 62, and the outdoor side wall 52A, the bottom 51, and the lower part of the indoor side wall 52B are formed of the sintered part 61. All of the outdoor protrusions 53A are formed of the sintered part 61.

[0080] In this way, the non-sintered portion 62 may be in contact with both the face material 41 and the lower frame 33 .

[0083] (Second embodiment) Next, a second embodiment of the present disclosure will be described with reference to Figures 11 to 14. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and will not be described again. The face material holding members of the second embodiment are beads 7 and 8. The beads 7 and 8 hold the outer peripheral edge portion 141a of the face material 141 of the fitting 101 in the fitting 101.

[0084] As shown in FIGS. 11 to 13, the fitting 101 of the second embodiment is a fixed window, and comprises a frame body 102 in the form of a frame on all four sides, and one surface material 141.

[0085] The frame 102 is made of a shaped material made of aluminum, an aluminum-resin composite, or a resin. The frame 102 has an upper frame 121, a lower frame 122, and a pair of left and right vertical frames 123.

[0086] The upper frame 121 is a long member extending in the left-right direction at the upper edge of the opening 100a. The lower frame 122 is a long member extending in the left-right direction at the lower edge of the opening 100a. Each vertical frame 123 is a long member extending in the up-down direction at the left or right edge of the opening 100a.

[0087] A groove 126 is provided on the inner peripheral surface of the frame 102. The groove 126 extends over the entire circumferential area of ​​the frame 102. The groove 126 opens toward the center of the opening 100a in the vertical and horizontal directions. The groove 126 has a U-shape in cross section.

[0088] A first indoor-side engaging portion 127A and a second indoor-side engaging portion 127B are provided on the outdoor-side portion of the inner circumferential surface of the groove portion 126. The first indoor-side engaging portion 127A is provided at the open end of the groove portion 126 and has a rectangular shape in cross section.

An indoor-side engaging portion 128 is provided on the indoor-side portion of the inner circumferential surface of the groove portion 126. The indoor-side engaging portion 128 has a generally L-shape in cross section.

[0089] The surface material 141 is a rectangular plate material held inside the frame body 102. The surface material 141 is, for example, a glass panel. The frame body 102 corresponds to a frame member.

[0090] Next, the configuration of the beads 7, 8 will be described using the beads 7, 8 arranged between the face material 141 and the lower frame 122 as an example.

[0091] As shown in Figure 14, beads 7, 8 include an outdoor bead 7 that is arranged on the outdoor side of face material 141 and extends along the outdoor side surface of face material 141, and an indoor bead 8 that is arranged on the indoor side of face material 141 and extends along the indoor side surface of face material 141.

[0092] The outdoor bead 7 extends along the outer peripheral edge 141a of the facing material 141. The outdoor bead 7 has, for example, a plurality of outdoor protrusions 73 that are convex toward the facing material 141. Each outdoor protrusion 73 is in contact with the facing material 141. Note that the position where the outdoor bead 7 contacts the outdoor surface of the facing material 141, the number of contact points, etc. are not particularly limited. The number, shape, dimensions, position, etc. of the outdoor beads 7 are not particularly limited.

[0093] The indoor bead 8 has a hollow portion 87 formed in the middle of the indoor bead 8 in the indoor / outdoor direction, and penetrating the indoor bead 8 in the left-right direction. Providing the hollow portion 87 in the indoor bead 8 makes it easier to fit the indoor bead 8 between the face material 141 and the lower frame 122, and can improve the vibration damping and sound insulation properties of the indoor bead 8.

[0094] The indoor bead 8 extends along the outer peripheral edge 141a of the facing material 141. The indoor bead 8 has, for example, a plurality of indoor protrusions 83 that are convex toward the facing material 141. Each indoor protrusion 83 is in contact with the facing material 141. Note that the position where the indoor bead 8 contacts the indoor surface of the facing material 141, the number of contact points, etc. are not particularly limited. The number, shape, dimensions, position, etc. of the indoor bead 8 are not particularly limited. Furthermore, the outdoor protrusions 73 and the indoor protrusions 83 may be collectively referred to as "protrusions 73, 83."

[0095] The outdoor bead 7 has a first outdoor engaged portion 75 that engages with the first outdoor engaging portion 127A and a second outdoor engaged portion 76 that engages with the second outdoor engaging portion 127B. The first outdoor engaging portion 127A is formed, for example, such that the outer surface of the outdoor bead 7 is recessed toward the indoor side. The second outdoor engaging portion 127B is formed, for example, such that the outer surface of the outdoor bead 7 is recessed toward the indoor side.

[0096] The indoor bead 8 has an indoor-side engaged portion 85 that engages with the indoor-side engaging portion 128. The indoor-side engaged portion 85 is formed, for example, by recessing the outer surface of the indoor-side bead 8 toward the outdoor side in a shape that corresponds to the indoor-side engaging portion 128.

[0097] Here, the exterior bead 7 has a sintered portion 78 and a non-sintered portion 79 .

[0098] The upper portion of the outdoor bead 7 facing the room is formed by a non-sintered portion 79. The non-sintered portion 79 is in contact with the facing material 141. This allows the non-sintered portion 79 to attenuate vibrations that would otherwise be transmitted from the facing material 141 to the outdoor bead 7, thereby improving sound insulation.

[0099] The portion of the upper part of the outdoor bead 7 facing the outdoor area and the lower part of the outdoor bead 7 are formed by the sintered portion 78. The entire portion of the outdoor bead 7 that comes into contact with the bottom frame 122 is formed by the sintered portion 78. The sintered portion 78 is disposed between the bottom frame 122 and the non-sintered portion 79. As a result, even if the non-sintered portion 79 burns, the sintered portion 78 can remain between the bottom frame 122 and the non-sintered portion 79, thereby improving flame protection.

[0100] The outer surface of the first outdoor engaged portion 75 and the outer surface of the second outdoor engaged portion 76 are formed by sintered portions 78. The entire portion of the outdoor bead 7 that comes into contact with the lower frame 122 is formed by sintered portions 78. This makes it easier to ensure contact between the outdoor bead 7 and the lower frame 122 even if the non-sintered portions 79 are lost, thereby improving flame protection.

[0101] The lowest one of the multiple outdoor protrusions 73 is formed by the sintered portion 78. In this way, the portions of the beads 7, 8 that come into contact with the face material 141 may include a portion formed by the non-sintered portion 79 and a portion formed by the sintered portion 78.

[0102] The indoor bead 8 has a sintered portion 88 and a non-sintered portion 89 .

[0103] The outdoor side portion of the indoor bead 8 is formed by the non-sintered portion 89. The outdoor side portion of the indoor bead 8 beyond the hollow portion 87 is formed by the non-sintered portion 89. The non-sintered portion 89 is in contact with the face material 141. This allows the non-sintered portion 89 to attenuate vibrations that attempt to be transmitted from the face material 141 to the indoor bead 8. The entire portion of the indoor bead 8 that comes into contact with the face material 141 is formed by the non-sintered portion 89. This allows vibrations that attempt to be transmitted from the face material 141 to the outdoor bead 7 to be attenuated more effectively, further improving sound insulation.

[0104] The indoor side portion of the indoor bead 8 is formed by a sintered portion 88. The sintered portion 88 is disposed between the non-sintered portion 89 and the lower frame 122. Therefore, even if the non-sintered portion 89 disappears, the sintered portion 88 remains between the face material 141 and the lower frame 122. This makes it possible to prevent the face material 141 from falling off in the event of a fire, thereby improving flame-blocking properties.

[0105] The entire outer surface of the indoor-side engaged portion 85 is formed by the sintered portion 88. The entire portion of the indoor-side bead 8 that comes into contact with the lower frame 122 is formed by the sintered portion 88. This makes it easier to ensure contact between the indoor-side bead 8 and the lower frame 122, even if the non-sintered portion 89 disappears, thereby improving flame-blocking properties.

[0106] Furthermore, the outdoor bead 7 has a sintered portion 78 and a non-sintered portion 79, and the indoor bead 8 has a sintered portion 88 and a non-sintered portion 89. This makes it possible to improve the flame and sound insulation properties on both sides of the face material 141 in the indoor / outdoor direction.

[0107] (Modification of the second embodiment) Next, first to fourth modified examples of the second embodiment will be described with reference to Figures 15 to 18. In the first to fourth modified examples of the second embodiment, the same components as those in the second embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0108] 15, in the beads 7, 8 of the first modified example of the second embodiment, the outdoor bead 7 is formed only from a sintered portion 78, and the indoor bead 8 is formed from a non-sintered portion 89 and a sintered portion 88. The configuration of the indoor bead 8 is the same as the configuration of the outdoor bead 7 of the second embodiment described above.

[0109] 16, in the beads 7, 8 of the second modified example of the second embodiment, the outdoor bead 7 is formed of a non-sintered portion 79 and a sintered portion 78, and the indoor bead 8 is formed only of a sintered portion 88. The configuration of the outdoor bead 7 is the same as the configuration of the indoor bead 8 of the second embodiment.

[0110] As described above, one of the outdoor bead 7 and the indoor bead 8 may be formed only from a sintered portion, while the other may be formed to include both a non-sintered portion and a sintered portion. The outdoor bead 7 and the indoor bead 8 are not limited to a configuration in which both include both a non-sintered portion and a sintered portion. By forming either the outdoor bead 7 or the indoor bead 8 from a single material, the outdoor bead 7 and the indoor bead 8 formed from a single material can be manufactured without two-color molding or the like. This simplifies the manufacturing of the beads 7, 8.

[0111] As shown in Figure 17, in the beads 7, 8 of the third modified example of the second embodiment, the outdoor bead 7 is formed only from a sintered portion 78, and the indoor bead 8 is formed only from a non-sintered portion 89.

[0112] As shown in Figure 18, in the beads 7, 8 of the fourth modified example of the second embodiment, the outdoor bead 7 is formed only from the non-sintered portion 79, and the indoor bead 8 is formed only from the sintered portion 88.

[0113] In this way, one of the outdoor bead 7 and the indoor bead 8 may be formed only from sintered portions, and the other may be formed only from non-sintered portions. Forming both the outdoor bead 7 and the indoor bead 8 from a single material makes it even easier to manufacture the components.
