DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 3 show 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 as shown in Figures 1 and 2, it comprises a frame 10 attached to a structural opening 9, and an outer shoji screen 11a and an inner shoji screen 11b housed in the frame 10 in a sliding manner so as to be able to open and close freely. The frame 10 is made up of an upper frame 12, a lower frame 2, and left and right vertical frames 1, 1 framed in a rectangular shape. The outer shoji screen 11a and the inner shoji screen 11b are made up of an upper frame 13, a lower frame 14, a door edge frame 15, and a joint frame 16 framed together, with glass (double glazing) 18 fitted inside.

[0008] As shown in Figure 1, the lower frame 2 is an insulating member consisting of an outdoor section 3 and an indoor section 4 made of extruded aluminum alloy, and a bridge member 5 connecting the outdoor section 3 and the indoor section 4. Tapping holes 17 are provided in each of the outdoor section 3 and the indoor section 4. The bridge member 5 is made of a material with insulating properties and blocks heat transfer between the outdoor section 3 and the indoor section 4. A core member 6 is embedded within the bridge member 5 over its entire length in the longitudinal direction to prevent shrinkage of the bridge member 5. This core member 6 is made of the same material (aluminum) as the outdoor section 3 and the indoor section 4, and has an approximately T-shaped cross section.

[0009] Figure 3 shows the manufacturing procedure for the lower frame 2. As shown in Figure 3(a), the lower frame 2 is originally extruded as a single piece of connected exterior and interior shape members 3 and 4. This shape member has a bridge material injection groove 19 with a roughly C-shaped cross section that is open on the inner periphery (top side) in the middle part in the indoor-outdoor direction. The bottom wall of the bridge material injection groove 19 forms the connecting part 7 that connects the exterior shape member 3 and the interior shape member 4, and the core material 6 with a T-shaped cross section is formed so that its base end is continuous with the middle part in the indoor-outdoor direction of the connecting part 7. Furthermore, protrusions 20 are formed longitudinally on the inner side surface of the bridge material injection groove 19 at upper and lower positions near the exterior side and at upper and lower positions near the interior side. As shown in Figure 3(a), a resin (e.g., polyurethane resin) 21 that will be the material for the bridge material 5 is injected into the bridge material injection groove 19 of this profile. When the resin 21 hardens, it bonds to the inner surface of the bridge material injection groove 19 and the outer surface of the core material 6. After the resin 21 has hardened, as shown in FIG. 3(b), the base of the core material 6 of the connecting portion 7 is cut away over the entire length of the lower frame 2 with a tool (not shown) to form a non-connecting portion 8, and the outdoor-side shape member 3 and the indoor-side shape member 4 are separated. As a result, the core material 6 is separated from the outdoor-side shape member 3 and the indoor-side shape member 4 and embedded in the bridge material 5.

[0010] The vertical frame 1 has a rubber sheet-like sealant 22 (see Figure 2) attached to the inner side surfaces of the upper and lower ends, and the lower frame 2, as shown in Figures 1 and 2, has its longitudinal end face abutted against the inner side surface of the vertical frame 1 via the sealant 22, and is connected and fixed to the vertical frame 1 by screwing screws 23 inserted from the side of the vertical frame 1 into tapping holes 17 in the exterior frame 3 and the interior frame 4.

[0011] As shown in Figure 1, the upper frame 12 is also an insulating member made up of an outdoor-side extrusion 24 and an indoor-side extrusion 25 made of aluminum alloy, and a resin bridge member 26 that connects the outdoor-side extrusion 24 and the indoor-side extrusion 25. However, unlike the lower frame 2, the upper frame 12 is made by inserting the outdoor-side end and indoor-side end of the pre-formed bridge member 26 into grooves in the outdoor-side extrusion 24 and the indoor-side extrusion 25, respectively, and crimping them to secure them in place.

[0012] In a conventional lower frame 2 that does not have a core material 6 in the bridge material 5, initially the longitudinal end faces of the bridge material 5, together with the exterior shape material 3 and the interior shape material 4, abut against the sealer 22 on the inner side surface of the vertical frame 1. However, due to factors such as the difference in the amount of thermal expansion between aluminum and resin, the bridge material 5 may shrink over time, and when the bridge material 5 shrinks, the longitudinal end faces of the bridge material 5 separate from the sealer 22 on the inner side surface of the vertical frame 1, creating a gap, which can allow rainwater that has infiltrated the top surface of the lower frame 2 to flow down through the gap and seep into the main body. This opening building material has the core material 6 embedded in the bridge material 5 over the entire longitudinal length, and the bridge material 5 is bonded to the outer peripheral surface of the core material 6, which prevents the bridge material 5 from shrinking in the longitudinal direction. This prevents gaps from forming between the longitudinal end faces of the bridge material 5 and the sealer 22 of the vertical frame 1, preventing water leakage to the main body 27 side. Since the core material 6 is formed with a T-shaped cross section, the contact area of ​​the core material 6 with the bridge material 5 is increased, which increases the adhesive strength between the core material 6 and the bridge material 5 and effectively prevents the bridge material 5 from shrinking.

[0013] 4 and 5 show a second embodiment of the building material for openings of the present invention. As shown in Fig. 5, the lower frame 2 of this embodiment is constructed by injecting resin 21 into the bridge material injection groove 19, and after the resin 21 has hardened, the corners on the indoor side of the bridge material injection groove 19 are cut away with a tool (not shown) to form non-connecting portions 8 at the indoor end positions of the connecting portions 7. The core material 6 is embedded in the bridge material 5 while remaining connected to the connecting portions 7. As with the first embodiment, the opening building material of this embodiment also uses the core material 6 to prevent longitudinal shrinkage of the bridge material 5, preventing gaps from opening between the longitudinal end faces of the bridge material 5 and the sealer 22 of the vertical frame 1, thereby preventing water leakage into the main body 27.

[0014] In the first and second embodiments, the core material 6 was connected to the bottom wall (connecting portion) 7 of the bridge material injection groove 19, but by connecting the core material 6 to the outdoor wall or indoor wall of the bridge material injection groove 19, the core material 6 can also be installed on the outdoor profile 3 or the indoor profile 4.

[0015] 6 and 7 show a third embodiment of the building material for openings of the present invention. As with the first and second embodiments, the lower frame 2 is an insulating shaped member consisting of an outdoor-side shaped member 3 and an indoor-side shaped member 4, each made of an aluminum alloy extrusion, and a bridge member 5 connecting the outdoor-side shaped member 3 and the indoor-side shaped member 4. As shown in FIGS. 3(a) and 3(b), the outdoor-side shaped member 3 and the indoor-side shaped member 4 were originally extruded as a single connected member. Resin 21, which is the material for the bridge member 5, was injected into a bridge member injection groove 19 formed in the middle of the member in the indoor-outdoor direction. After the resin 21 hardened, the middle part of the indoor-outdoor direction of the bottom wall (connecting portion) 7 of the bridge member injection groove 19 was cut away with a tool along the longitudinal direction to form the non-connecting portion 8.

[0016] In the lower frame 2 of this embodiment, instead of embedding the core material 6 in the bridge material 5 as in the first and second embodiments, as shown in FIG. 7 , when the connecting portions 7 are cut to separate the exterior-facing frame 3 and the interior-facing frame 4, the connecting portions 7 are left uncut at both longitudinal ends of the lower frame 2. This connects the exterior-facing frame 3 and the interior-facing frame 4 at both longitudinal ends, and the exposed outer surface of the bridge material 5 is joined to the uncut connecting portions 7. The length a of the uncut portion of the connecting portion 7 is, for example, approximately 30 mm from the longitudinal end face of the lower frame 2. Note that the length a of the uncut portion of the connecting portion 7 only needs to be longer than the dimension of the gap that may occur due to shrinkage of the bridge material 5, and may be, for example, a few millimeters depending on the length of the lower frame 2. Furthermore, the entire space between the uncut connecting portions 7, 7 at both ends may be left as a non-connecting portion 8, or one or more connecting portions 7 may be left uncut in the middle of the longitudinal direction.

[0017] In the opening building material of this embodiment, even if the bridge material 5 of the sill 2 shrinks and a gap forms between the longitudinal end face of the bridge material 5 and the sealer 22 of the vertical frame 1, the end face of the connecting part 7 connecting the exterior shape member 3 and the interior shape member 4 abuts against the sealer 22 of the vertical frame 1, so the gap between the longitudinal end face of the bridge material 5 and the sealer 22 is closed by the connecting part 7, and water does not leak into the main body 27. The exterior shape member 3 and the interior shape member 4 are connected by the connecting part 7 for only a small part of the entire length of the sill 2, and for the most part the exterior shape member 3 and the interior shape member 4 are separated by the non-connecting part 8, so the bridge material 5 provides sufficient insulation performance.

[0018] Even in the first and second embodiments in which the core material 6 is embedded in the bridge material 5, as in the third embodiment, the connecting portions 7 can be left uncut to a predetermined length at both longitudinal ends of the lower frame 2, so that the exterior-side shape member 3 and the interior-side shape member 4 are connected by the connecting portions 7 at both longitudinal ends of the lower frame 2. In this way, even if the bridge material 5 shrinks, the uncut connecting portions 7 can prevent water leakage into the main body 27.

[0019] As described above, this opening building material (first and second embodiments) comprises a vertical frame 1 and a horizontal frame (bottom frame) 2. The horizontal frame 2 is made up of an exterior-facing shape 3, an interior-facing shape 4, and a bridge material 5 connecting the exterior-facing shape 3 and the interior-facing shape 4. The longitudinal end faces abut against the inner peripheral side surfaces of the vertical frame 1 (strictly speaking, against the sealer 22 attached to the inner peripheral side surfaces of the vertical frame 1), and the exterior-facing shape 3 and the interior-facing shape 4 are screwed to the vertical frame 1. The core material 6 is embedded inside the bridge material 5 over its entire length, thereby providing thermal insulation performance and preventing shrinkage of the bridge material 5 in the longitudinal direction by the core material 6, which prevents gaps from occurring between the longitudinal end faces of the bridge material 5 and the vertical frame 1 and prevents water leakage into the main body 27, making it easy to use. The outdoor section 3 and the indoor section 4 are separated by injecting resin 21 into a bridge material injection groove 19 formed in the middle of the indoor / outdoor direction, and then cutting off the connecting section 7 after the resin 21 has hardened.A portion of the connecting section 7, the outdoor section 3, or the indoor section 4 remains embedded inside the bridge material 5 over its entire length as a core material 6, so there is no need to prepare a separate core material 6 and embed it in resin, and it can be manufactured in the same way as a normal cast-type insulating section, which is rational.

[0020] Furthermore, this opening building material (third embodiment) comprises a vertical frame 1 and a horizontal frame (bottom frame) 2, and the horizontal frame 2 consists of an outdoor-side profile 3, an indoor-side profile 4, and a bridge material 5 connecting the outdoor-side profile 3 and the indoor-side profile 4, with its longitudinal end face abutting the inner peripheral side of the vertical frame 1, and the outdoor-side profile 3 and the indoor-side profile 4 being screwed to the vertical frame 1, and the outdoor-side profile 3 and the indoor-side profile 4 being connected at least at both longitudinal ends by connecting parts 7, which are joined to the visible surface of the bridge material 5 and have non-connecting parts 8 in the middle of the longitudinal direction, thereby providing thermal insulation performance and, even when the bridge material 5 shrinks, the connecting parts 7 abut against the inner peripheral side of the vertical frame 1, preventing water leakage into the main body 27, making it easy to use. In this opening building material (third embodiment), resin 21 is injected into the bridge material injection groove 19 of the extruded shape while the outdoor-side shape 3 and the indoor-side shape 4 are connected, and after the resin 21 hardens, the connecting portion 7 is cut away to separate the outdoor-side shape 3 and the indoor-side shape 4, and it is only necessary to leave the connecting portion 7 at both longitudinal ends of the horizontal frame 2, so that the entire longitudinal end face of the horizontal frame 2 abuts against the inner side surface of the vertical frame 2 while maintaining insulation performance, and no gaps for water leakage are created, thereby reliably preventing water leakage into the main body 27.

[0021] The present invention is not limited to the above-described embodiments. The cross-sectional shapes of the exterior and interior shapes can be modified as needed. The exterior and interior shapes only need to be connected by connecting portions at least at both longitudinal ends of the sill, and the position and length of the connecting portions can be modified as needed. The vertical frames can be mullions, and the horizontal frames can be plain. The present invention is not limited to sliding windows, but can be applied to all types of opening building materials, such as fixed windows, sliding windows, entrance doors, service doors, and curtain walls.
