[Brief explanation of the drawings]
[0006] [Figure 1] 1 is a cross-sectional view showing a first embodiment of a building material for openings according to the present invention. [Figure 2] FIG. 2 is a cross-sectional view showing a second embodiment of the building material for openings of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows a first embodiment of the building material for openings of the present invention. This building material for openings is applied to a sliding window for a house, and includes a frame 1 attached to an opening in the building frame, and an outer shoji screen 2a and an inner shoji screen 2b housed within the frame 1 in a sliding manner so that they can be opened and closed freely.
[0008] The outer shoji screen 2a and the inner shoji screen 2b are constructed by assembling an upper frame, a lower frame, a door edge frame 3a, 3b, and a joint frame 4a, 4b, with double-glazed glass 5 housed inside. Each frame 3a, 3b, 4a, 4b has a groove 6 that opens on the inner periphery, and the edge of the double-glazed glass 5 is fitted and held in place in the groove 6 via a glass channel (not shown).
[0009] The door frames 3a, 3b of the outer shoji screen 2a and the inner shoji screen 2b are composed of an aluminum exterior profile 7 placed on the outside of the room and a resin interior profile 8 placed on the inside of the room. The exterior profile 7 has a pair of outward-facing hook-shaped engaging portions 9, 9 in the longitudinal direction on the interior side, and the interior profile 8 has a pair of inward-facing hook-shaped engaging portions 10, 10 in the longitudinal direction on the exterior side, and the exterior profile 7 and the interior profile 8 are joined by fitting the engaging portions 9, 9, 10, 10 together. The interior profile 8 has multiple hollow portions 19 stacked in the inner and outer periphery directions and in the projection direction.
[0010] A thin sheet-like insulating material 11 is arranged between the indoor side of the outdoor-side profile 7 and the outdoor side of the indoor-side profile 8. The sheet-like insulating material 11 is provided over almost the entire length of the outdoor-side profile 7 and the indoor-side profile 8, and also over almost the entire area of the opposing surfaces of the outdoor-side profile 7 and the indoor-side profile 8. Both edge portions of the sheet-like insulating material 11 are sandwiched between the mating portions of the outdoor-side profile 7 and the indoor-side profile 8. More specifically, both edge portions of the sheet-like insulating material 11 are sandwiched between the mating portions 9, 9 of the outdoor-side profile 7 and the outdoor side of the indoor-side profile 8.
[0011] The sheet-like insulating material 11 has heat insulating properties and water repellency or hydrophobicity (the same applies to the sheet-like insulating materials 14 and 18 in the other parts described later). The sheet-like insulating material 11 is not limited to any particular material, but may be, for example, one that uses aerogel or one that is made of a polyethylene sheet coated with aluminum. An example of a material using aerogel is a sheet made by mixing silica aerogel with synthetic fiber (polyester). Silica aerogel is a porous material that is 90% or more air and is hydrophobic, making it immiscible with water. When this material is made into a sheet, the insulating material 11 is very thin, measuring 0.05 to 1 mm, and has extremely high thermal insulation properties, with a thermal conductivity of 0.013 to 0.027 W / m·K. Furthermore, this insulating material 11 is easy to cut with scissors, and can be folded or bent, making it highly workable. Furthermore, this insulating material 11 can be non-flammable or flame-retardant.
[0012] The door sills 3a, 3b can be manufactured by attaching sheet-like insulation material 11 to the outdoor side surface of the indoor-side profile 8 with double-sided tape, and then fitting and joining the outdoor-side profile 7 and the indoor-side profile 8 at the engagement parts 9, 9, 10, 10. The sheet-like insulation material 11 may be attached to the outdoor-side profile 7 with double-sided tape. Alternatively, an adhesive layer with a release paper may be provided on one side of the sheet-like insulation material 11, and the release paper may be peeled off and the insulation material may be attached to either the outdoor-side profile 7 or the indoor-side profile 8. Alternatively, the insulation material may simply be sandwiched between the outdoor-side profile 7 and the indoor-side profile 8 without being attached to either the outdoor-side profile 7 or the indoor-side profile 8.
[0013] The joint frame 4b of the inner shoji screen 2b is made by joining an aluminum exterior profile 12 placed on the outside of the room with a resin interior profile 13 placed on the inside of the room, and a sheet-like heat insulating material 14 is placed between the exterior profile 12 and the interior profile 13. The interior profile 13 covers the outer peripheral side 12a and the interior side 12b of the exterior profile 12, and the sheet-like heat insulating material 14 is bent into an L shape and is provided over almost the entire surface of the opposing exterior profile 12 and interior profile 13. The joint frame 4a of the outer shoji screen 2a is made from a single aluminum section because it does not come into contact with the interior space.
[0014] Like the door end frames 3a and 3b, the upper and lower frames are made by joining an aluminum exterior profile placed on the outside of the room with a plastic interior profile placed on the inside of the room, with sheet-like insulation material placed between the exterior and interior profiles.
[0015] The frame 1 is composed of an upper frame, a lower frame, and left and right vertical frames 15, 15. The vertical frame 15 is composed of an aluminum exterior frame 16 and a resin interior frame 17 that covers the portion of the exterior frame 16 that is exposed to the interior, and a sheet-like heat insulating material 18 is provided on the entire inner peripheral surface of the exterior frame 16 that faces the interior frame 17.
[0016] Like the vertical frame 15, the upper and lower frames also have sheet-like insulating material sandwiched between an aluminum exterior profile and a plastic interior profile.
[0017] This opening building material features sheet-like insulation 11, 14, 18 between the frames 3a, 3b, 4b and 15 of the shoji screens 2a, 2b, the aluminum exterior frames 7, 12, 16, and the resin interior frames 8, 13, 17. This prevents heat transfer between the exterior frames 7, 12, 16 and the interior frames 8, 13, 17, resulting in improved insulation compared to conventional aluminum-resin composite sashes. Furthermore, the use of sheet-like insulation 11, 14, 18 makes it possible to reduce or eliminate the hollow space 19 in the interior frames 8, 13, 17, thereby reducing the expected dimensions of the frames and other components. Furthermore, by selecting whether or not to use sheet-like insulation 11, 14, 18, opening building materials with different insulation performance can be provided. The sheet-like heat insulating materials 11, 14, 18 are water-repellent or hydrophobic, and therefore can be prevented from breaking or changing in quality even if rainwater or condensed water penetrates between the exterior shape members 7, 12, 16 and the interior shape members 8, 13, 17, and are therefore highly durable.
[0018] Figure 2 shows a second embodiment of the opening construction material of the present invention. The door frame sills 3a, 3b of the outer and inner shoji screens 2a, 2b are made of aluminum, with the exterior and interior members 7, 8 made of aluminum. Sheet-like insulation 11 is sandwiched between the two members 7, 8 to prevent contact between the exterior and interior members 7, 8, and the sheet-like insulation 11 blocks heat transfer between the exterior and interior members 7, 8. The exterior and interior members 7, 8 are fastened together with screws 20 from the inner and outer peripheries, and resin washers 21 are used to prevent heat transfer between the exterior and interior members 7, 8 through the screws 20. Like the door end frames 3a and 3b, the outer frame 12 and the inner frame 13 of the inner shoji door 2b's joint frame 4b are both made of aluminum, and by sandwiching sheet-like insulation material 14 between the two frames 12 and 13, the outer frame 12 and the inner frame 13 are prevented from coming into contact with each other, and the sheet-like insulation material 14 blocks heat transfer between the outer frame 12 and the inner frame 13. The outer frame 12 and the inner frame 13 are fixed with screws 20 from the outside and the inside, and resin washers 21 are used to prevent heat transfer between the outer frame 12 and the inner frame 13 through the screws 20.
[0019] In the opening building material of the second embodiment, the outdoor-side shaped members 7, 12 and the indoor-side shaped members 8, 13 are both made of aluminum, but the sheet-like insulating materials 11, 14 placed between the two shaped members block heat transfer between the outdoor-side shaped members 7, 12 and the indoor-side shaped members 8, 13, thereby demonstrating excellent insulating performance. Because the indoor-side shaped members 8, 13 are made of aluminum, they are strong, resistant to the heat of a fire, and have a good design. In addition, because the indoor-side shaped members 8, 13 are made of aluminum and the insulating materials 11, 14 are thin and sheet-like, the projected dimensions can be made small.
[0020] As described above, the insulating properties of the building material for openings (first and second embodiments) are improved by disposing the sheet-like insulating materials 11, 14, 18 having insulating properties between the exterior shape members 7, 12, 16 and the interior shape members 8, 13, 17. Moreover, the sheet-like insulating materials 11, 14, 18 are water-repellent or hydrophobic, and therefore have good durability. Since the sheet-like heat insulating materials 11, 14, 18 are provided over almost the entire length of the exterior shape members 7, 12, 16 and the interior shape members 8, 13, 17, heat is not transmitted from any part of the entire length of the exterior shape members 7, 12, 16 and the interior shape members 8, 13, 17, and high heat insulating performance is obtained. In addition, the sheet-like insulation materials 11, 14, 18 are provided over almost the entire area of the opposing surfaces of the exterior profile members 7, 12, 16 and the interior profile members 8, 13, 17, thereby reliably blocking heat transfer between the exterior profile members 7, 12, 16 and the interior profile members 8, 13, 17. In the first embodiment of the opening building material, the outdoor section members 7, 12, 16 and the indoor section members 8, 13, 17 are joined by fitting, and the sheet-like insulating materials 11, 14, 18 are sandwiched between the fitting portions of the outdoor section members 7, 12, 16 and the indoor section members 8, 13, 17, so that the sheet-like insulating materials 11, 14, 18 can be installed stably and heat transfer between the outdoor section members 7, 12, 16 and the indoor section members 8, 13, 17 can be reliably blocked. In the second embodiment of the opening building material, the outdoor profile members 7, 12, 16 and the indoor profile members 8, 13, 17 are screwed together in a way that prevents heat from being transferred, so that the outdoor profile members 7, 12, 16 and the indoor profile members 8, 13, 17 can be firmly connected by screwing, and heat transfer between the outdoor profile members 7, 12, 16 and the indoor profile members 8, 13, 17 can be prevented through the screws 20.
[0021] The present invention is not limited to the above-described embodiments. The exterior and interior shapes can be any components that make up a building fixture, including frames, stiles, mullions, and crossbeams. The building material for openings of the present invention does not necessarily need to have sheet-type insulation material on all components; it is sufficient that at least one component has sheet-type insulation material. The cross-sectional shapes and materials of the exterior and interior shapes can be changed as appropriate. The sheet-type insulation material may be any material, as long as it has thermal insulation properties and is water-repellent or hydrophobic. [Explanation of symbols]
