Description

[Technical Field]

[0001] The present invention relates to a fitting and a method for manufacturing the fitting. [Background technology]

[0002] Modern building fixtures are required to have high fire resistance. For this reason, building fixtures have been provided in which a fixed-shaped thermal expansion member is attached to building materials such as frames and stiles, or reinforcing materials that reinforce frames and stiles. When this type of building fixture is exposed to high temperatures during a fire, the thermal expansion member expands due to the heat, closing the gap between the frame and stile. As a result, it is possible to prevent flames from penetrating inside and outside the building, and improve fire resistance (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-56664 Summary of the Invention [Problem to be solved by the invention]

[0004] Some building materials are placed on the edges of panel materials, and some are designed to have a thermal expansion member placed inside the panel material receiving groove. However, in these panel material receiving grooves, a support member called a setting block is often provided between the panel material and the building material. Therefore, even if a thermal expansion member is placed along the entire length of the panel material receiving groove, there is a concern that the thermal expansion of the thermal expansion member may be hindered in the area covered by the support member.

[0005] In view of the above circumstances, the present invention aims to provide a fitting and a method for manufacturing the fitting that can achieve further improvement in fire resistance. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the building fixture of the present invention is a building fixture constructed by placing building materials on the edge of a panel, and the building material placed on the lower edge of the panel has a heat-expansion member provided in a position that supports the load of the panel, and the panel is placed on the building material using the heat-expansion member as a support member, and the panel is a double-glazed glass panel made by stacking multiple glass panels via spacer members, and the heat-expansion members are provided in a position that overlaps each glass panel in the projection direction, and the heat-expansion members are arranged side by side in the projection direction with gaps between them, and one of the heat-expansion members arranged side by side has a first part having a length that extends continuously over the entire length of the glass panel in the longitudinal direction of the building material, and a second part arranged overlapping a part of the first part, and the other heat-expansion member arranged side by side is arranged side by side with the second part and is arranged so that the height of its upper surface coincides with the upper surface of the second part. [Effects of the Invention]

[0007] According to the present invention, the thermally expandable member is used as a supporting member to place the surface material on the building material, so that when the temperature becomes high, the gap with the surface material can be reliably filled, thereby improving fire resistance.

[0009] Preferred embodiments of fittings and methods for manufacturing fittings according to the present invention will be described in detail below with reference to the accompanying drawings. For convenience, the terms "prospect direction" and "visibility direction" will be used below. The prospect direction is the direction along the depth of the fitting, as indicated by arrow A in the drawing. A surface along the prospect direction may be referred to as a "prospect surface." The prospect direction is the direction perpendicular to the prospect direction for items that extend horizontally, such as a sill frame. For items that extend vertically, such as a vertical frame, the horizontal direction perpendicular to the prospect direction is referred to as the "prospect direction." A surface along the prospect direction may be referred to as a "prospect surface."

[0010] FIG. 1 conceptually illustrates a manufacturing method for a fitting according to an embodiment of the present invention. The fitting material 10 illustrated here is used as a stile, which is placed at the bottom edge of the panel of a shoji screen, or as a sill, which is placed at the bottom edge of the panel of a fixed window. The fitting material used as this stile or sill (hereinafter simply referred to as lower fitting material 10) may be a metal-only material made of an extruded metal such as an aluminum alloy, a resin-only material made of an extruded resin, or a composite type having a metal portion made of an extruded metal and a resin portion made of an extruded resin. In any case, the lower fitting material 10 is configured so that its entire length along its longitudinal axis (the direction perpendicular to the projection direction) has a substantially uniform cross-sectional shape. The specific examples shown in FIGS. 2 and 3 illustrate a shoji screen for a sliding window, each incorporating a composite lower fitting material 10 having a resin portion 10A on the interior side and a metal portion 10B on the exterior side. The face material 20 is a double-glazed glass in which two glass sheets 22, 23 are laminated with a spacer member 21 interposed therebetween and a gasket 24 is attached to the outer periphery of the glass sheets 22, 23. In this embodiment, in particular, a double-glazed glass in which a float glass 22 and a wired glass 23 having a higher fire resistance than the float glass 22 are laminated is used.

[0011] As shown in FIG. 1 , the lower building material 10 has a surface material storage section 12 above the building material body 11. The building material body 11 has at least a portion extending along the projection direction. In the illustrated example, the building material body 11 has a cylindrical shape with a rectangular cross section. However, the building material body 11 does not necessarily have to be cylindrical; for example, it may simply be a plate-like shape extending along the projection direction. The surface material storage section 12 is a recess formed between the support walls 13 on the inner periphery of the building material body 11 by providing support walls 13 from the interior-facing and exterior-facing edges of the building material body 11 toward the inner periphery. The dimension of the surface material storage section 12 along the projection direction is configured to accommodate the surface material 20. The support walls 13 may be molded integrally with the building material body 11, or they may be molded separately from the building material body 11 as a ridge and then attached to form the surface material storage section 12. Also, as shown in Figures 2 and 3, if the lower building material 10 is a composite type, a surface material storage section 12 may be formed between the support wall section 13 provided on the metal part 10B and the support wall section 13 provided on the resin part 10A.

[0012] As shown in Figure 1, a thermally expandable member 30 is provided inside the face material accommodating section 12 of the lower building material 10. The thermally expandable member 30 is a non-combustible or flame-retardant fire-resistant member that expands when heated, and can be applied in a fluid state, and then hardens to maintain the state of being applied to the lower building material 10. For example, an example of this type of thermally expandable member 30 that can be applied is one in which adhesive properties are added by mixing an adhesive into thermally expandable graphite.

[0013] When providing the thermal expansion member 30 on the lower building material 10, the thermal expansion member 30 in a fluid state is discharged from the nozzle N, and the lower building material 10 and the nozzle N are moved relatively along the length of the lower building material 10, thereby making it possible to continuously apply the thermal expansion member 30 to the building material body 11 in a desired width and thickness. After applying the thermal expansion member 30, it is sufficient to harden the thermal expansion member 30 over time or by chemical treatment such as mixing a curing agent to promote the hardening reaction.

[0014] As shown in FIG. 2, when placing the face material 20 in the face material storage section 12 via a reinforcing material 40, the thermal expansion member 30 can be provided on the upper surface of the reinforcing material 40. The reinforcing material 40 is made of a metal, such as steel, that has a higher fire resistance than the underlying building material 10, and includes a main plate 41 that is positioned approximately horizontally above the building material body 11, and support plate portions 42 that extend upward from both side edges of the main plate 41. Although not shown in the figure, the reinforcing material 40 is attached to the underlying building material 10 by screwing the main plate 41 into the building material body 11. If the upper surface of the main plate 41 is flat, the application of the thermal expansion member 30 can be simplified. In other words, by maintaining a constant amount of the thermally expandable material 30 discharged from the nozzle N and moving the lower building material 10 relative to the nozzle N at a constant speed, the applied thermally expandable material 30 can be made to a uniform thickness and have a flat upper surface.

[0015] On the other hand, as shown in FIG. 3, when placing the surface material 20 in the surface material storage section 12 without providing a reinforcing material 40, the amount of the thermal expansion material 30 dispensed from the nozzle N and the relative movement speed between the lower building material 10 and the nozzle N are controlled to apply the thermal expansion material 30 so that the top surface of the thermal expansion material 30 is horizontal, regardless of the shape of the inner bottom surface of the surface material storage section 12, i.e., the top surface of the building material main body 11. That is, in the illustrated lower building material 10, approximately cylindrical screw holes 11a are provided so as to protrude from the top surface of the building material main body 11, and joints 11b between the metal portion 10B and the resin portion 10A are configured to protrude from the top surface of the building material main body 11. In contrast, the thermal expansion material 30 is applied so as to be positioned above the screw holes 11a and joints 11b, and is provided on the lower building material 10 so that the top surface is flat, regardless of the uneven shapes of the screw holes 11a and joints 11b. As described above, the thermal expansion member 30 is in a fluid state when applied. Therefore, even if the top surface of the building material body 11 has a complex shape, it is possible to easily apply the thermal expansion member 30 so that the top surface is flat. In particular, if the top surface of the building material body 11 is flat but inclined, it is difficult to create a horizontal top surface by applying a fixed-shape thermal expansion member. However, by applying the fluid thermal expansion member 30, it is possible to easily create a horizontal top surface.

[0016] As shown in Figures 2 to 4, in this embodiment, thermal expansion members 30 are arranged side by side in the forward direction of the panel accommodating section 12, with a gap between them at the indoor-side edge and the outdoor-side edge. The indoor-side thermal expansion member 30 is composed of two layers, an upper layer and an lower layer. The lower thermal expansion member (hereinafter, when distinguished, referred to as the first thermal expansion member (first portion) 30A) is a portion that extends almost the entire length of the lower building material 10 along its length and is continuous with at least the entire length of the lower end face of the panel 20. In contrast, the upper thermal expansion member (hereinafter, when distinguished, referred to as the second thermal expansion member (second portion) 30B) is partially arranged at two positions equidistant from the center plane that bisects the length of the panel 20. The two second thermal expansion members 30B have approximately the same longitudinal dimensions and approximately the same upper surface height. The width of the second thermal expansion member 30B is approximately the same as the width of the first thermal expansion member 30A. The thermal expansion member on the outdoor side (hereinafter referred to as the third thermal expansion member 30C when distinguished) is configured as a single layer and is partially installed at two locations spaced apart from each other so as to be parallel to the location where the second thermal expansion member 30B is installed. The longitudinal dimension of the third thermal expansion member 30C is approximately the same as that of the second thermal expansion member 30B, and the height of its upper surface is also approximately the same as that of the second thermal expansion member 30B. As is clear from the figure, the dimension of the second thermal expansion member 30B along the projection direction is set to be larger than the thickness of the float glass 22 and is installed in a position overlapping the entire width of the lower surface of the float glass 22 in the projection direction. Similarly, the dimension of the third thermal expansion member 30C along the projection direction is set to be larger than the thickness of the wired glass 23 and is installed in a position overlapping the entire width of the lower surface of the wired glass 23 in the projection direction. The gap between the second thermal expansion member 30B and the third thermal expansion member 30C has a dimension along the projection direction that is smaller than the overall width of the spacer member 21 in the face material 20, and is located at a position that is included within the projection direction width relative to the underside of the spacer member 21.

[0017] In the figure, reference numeral 31 denotes a thermal expansion member provided inside the building material body 11, and reference numeral 32 denotes a thermal expansion member provided on the skirt portion 11c arranged so as to face the rail of the lower frame (not shown). These thermal expansion members 31 and 32 are formed in advance into thin strip shapes, similar to conventional ones, and are attached to the building material 10 with adhesive tape or glue.

[0018] With the lower building material 10 configured as described above, when the face material 20 is placed in the face material storage section 12, the gasket 24 of the face material 20 abuts against the upper surfaces of the second thermal expansion member 30B and the third thermal expansion member 30C, and the load of the face material 20 is supported by these thermal expansion members 30A, 30B, and 30C as support members. This makes it possible to support the face material 20 on the lower building material 10 without the need for a separate member such as a setting block. Moreover, as described above, because the thermal expansion members 30A, 30B, and 30C are applied in a fluid state, the upper surface against which the face material 20 abuts can be easily set flat regardless of irregularities such as screw holes 11a provided on the upper surface of the building material main body 11, eliminating the risk of problems such as the face material 20 tilting relative to the lower building material 10. Furthermore, with building materials that support the surface material 20 in the manner described above, there are no components between the surface material 20 that hinder the thermal expansion of the heat-expandable member 30, so in the event of a fire, the gap between the lower building material 10 and the surface material 20 can be reliably sealed, which is also advantageous in terms of fire prevention.

[0019] In the above-described embodiment, the first thermal expansion member is provided over almost the entire length of the building material, while the second and third thermal expansion members, which serve as support members, are provided only in portions of the building material that are partially aligned with the longitudinal dimension. This reduces the cost of manufacturing the building material. However, like the first thermal expansion member, the second and third thermal expansion members may also be provided over almost the entire length of the building material. Furthermore, while the thermal expansion members are arranged side by side in the projection direction with a gap between them, this is not necessarily limited to this configuration; the thermal expansion members may be arranged across the entire width of the building material in the projection direction. In this case, the surface material to be used in the building material is not necessarily limited to double-glazed glass consisting of two laminated glass sheets. While the above-described embodiment illustrates a surface material consisting of two laminated glass sheets with different fire resistances, the present invention is not limited to this configuration. Furthermore, the building material is not necessarily limited to those having an uneven inner bottom surface in the surface material housing, and can of course also be applied to those having a flat inner bottom surface.

[0020] In the above-described embodiment, the thermal expansion material is applied to the building material by ejecting it from the nozzle, but this is not necessarily limited to this, and other methods may be used as long as the thermal expansion material is in a fluid state. For example, the thermal expansion material may be applied to the building material by a brush, or by spraying the thermal expansion material onto the building material.

[0021] Furthermore, in the above-described embodiment, a thermal expansion member is applied whose dimension along the projection direction is set larger than the thickness of the glass plate, and the thermal expansion member is arranged at a position that overlaps the entire width of the underside of the glass plate in the projection direction, but the present invention is not limited to this, and it is also possible to arrange the thermal expansion member so that it overlaps only a portion of the glass plate in the projection direction, for example.

[0022] As described above, the building fixture of the present invention is a building fixture constructed by placing a building material on the edge of a surface material, and is characterized in that the building material placed on the lower edge of the surface material has a heat-expanding member that is applied in a fluid state and hardened at a position that supports the load of the surface material, and the surface material is placed on the building material using the heat-expanding member as a supporting member. According to this invention, the thermal expansion member is used as a support member to place the facing material on the building material, so that the gap with the facing material can be reliably filled when the temperature becomes high, thereby improving fire resistance. Moreover, because the thermal expansion member is applied in a fluid state and then hardened, even if the building material has unevenness, the upper surface of the thermal expansion member can be easily flattened, which is advantageous for placing the facing material.

[0023] The present invention is also characterized in that, in the above-mentioned building fixture, the surface material is double-glazed glass made by stacking multiple glass plates via spacer members, and the thermal expansion member is arranged in a position overlapping each glass plate in the projection direction. According to this invention, the face material can be reliably supported, and there is no risk of problems such as tilting occurring.

[0024] The present invention is also characterized in that, in the above-mentioned building fixture, the thermally expandable members are arranged side by side in the forward direction with gaps between them. According to this invention, it is possible to reduce the amount of thermal expansion member used.

[0025] The present invention is also characterized in that, in the above-mentioned building fixture, one of the thermally expandable members arranged side by side has a first portion having a length that extends continuously over the entire length of the glass plate in the longitudinal direction of the building material, and a second portion that is arranged overlapping a part of the first portion, and the other of the thermally expandable members arranged side by side is arranged side by side with the second portion and is arranged so that the height of its upper surface coincides with the height of the upper surface of the second portion. According to this invention, the amount of thermally expandable member used can be further reduced.

[0026] In addition, the manufacturing method of building materials according to the present invention is a manufacturing method of building materials that is constructed by placing building materials on the edge of a surface material, and is characterized in that a heat-expanding material in a fluid state is applied to the building material placed on the lower edge of the surface material at a position that supports the load of the surface material, and after the heat-expanding material has hardened, the surface material is placed on the building material using the heat-expanding material as a supporting member. According to this invention, the thermally expandable member is used as a supporting member to place the surface material on the building material, so that when the temperature becomes high, the gap with the surface material can be reliably filled, thereby improving fire resistance.
