Embodiments for Carrying Out the Invention

[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 5 show a first embodiment of the opening building material of the present invention. This opening building material is applied to a sliding window for housing, and as shown in FIGS. 1 and 2, it includes a frame 10 attached to a building opening 9, and an outer shutter 11a and an inner shutter 11b that are slidably housed in the frame 10 in a sliding manner. The frame 10 is configured by framing an upper frame 12, a lower frame 2, and left and right vertical frames 1 and 1 into a rectangle. The outer shutter 11a and the inner shutter 11b are framed by an upper frame 13, a lower frame 14, a door tip frame 15, and a mating frame 16, and glass (double-layer glass) 17 is fitted inside thereof.

[0008] As shown in FIG. 1, the lower frame 2 is a heat-insulating profile made of an extruded profile of an aluminum alloy, including an outdoor profile 5 and an indoor profile 6, and a bridge material 7 connecting the outdoor profile 5 and the indoor profile 6. Tapping holes 18 are provided in the outdoor profile 5 and the indoor profile 6 respectively. The bridge material 7 is formed of a material having heat-insulating performance and blocks heat transfer between the outdoor profile 5 and the indoor profile 6. The lower frame 2 is a so-called cast-in type heat-insulating profile. The outdoor profile 5 and the indoor profile 6 were originally integrally formed in a connected state, and a resin (for example, polyurethane resin) serving as the material of the bridge material 7 was injected into a bridge material injection groove formed along the longitudinal direction in the middle part of the profile in the indoor-outdoor direction. After the resin hardened, the bottom wall of the bridge material injection groove was cut off from the outer peripheral side and separated from the outdoor profile 5 and the indoor profile 6 (the reference numeral 19 in FIG. 3 indicates the separation part).

[0009] The vertical frame 1 has rubber sheet-like seals 8 (see FIGS. 2 and 4) adhered to the inner peripheral surfaces of the upper and lower ends. As shown in FIGS. 1 and 2, the lower frame 2 has its longitudinal end faces contacting the inner peripheral surface of the vertical frame 1 via the seal 8, and is connected and fixed to the vertical frame 1 by screwing a screw 20 inserted from the side of the vertical frame 1 into the tapping holes 18 of the outdoor-side profile 5 and the indoor-side profile 6.

[0010] On the outer peripheral side of the longitudinal end of the lower frame 2, as shown in FIGS. 1 and 2, there are provided a packing (waterstop material) 3 and a pressing member 21 for pressing the packing 3 from the outer peripheral side. The packing 3 is formed of a flexible material such as rubber or soft resin, and as shown in FIG. 1, it is press-contacted across the indoor-side end of the outer peripheral surface of the outdoor-side profile 5, the outdoor-side end of the outer peripheral surface of the indoor-side profile 6, and the outer peripheral surface of the bridge member 7 exposed from the separation portion 19 between the outdoor-side profile 5 and the indoor-side profile 6. Also, as shown in FIG. 2, the packing 3 is provided at a predetermined length (for example, about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it contacts the seal 8 of the vertical frame 1. The pressing member 21 is formed by bending a metal plate such as stainless steel into a crank shape. The raised outdoor-side piece 22 presses the packing 3 from the outer peripheral side, and the indoor-side piece 23 is in contact with the lower surface of the indoor-side profile 6 and fixed by a screw 24 from below. As shown in FIG. 3(a), the packing 3 is in a block shape with a substantially square cross-section before being attached to the lower frame 2, and is attached by adhering it to the outdoor-side piece 22 of the pressing member 21 with a double-sided tape or the like. Then, when the screw 24 passed through the indoor-side piece 23 of the pressing member 21 is screwed into the female screw hole 25 formed in the indoor-side profile 6 and tightened, the packing 3 is pressed by the outdoor-side piece 22 of the pressing member 21 and compressed in the vertical direction and expands around, so that the upper surface of the packing 3 is press-bonded across the outer peripheral surfaces of the outdoor-side profile 5, the bridge member 7, and the indoor-side profile 6, and the longitudinal end face is press-bonded to the seal 8.

[0011] The upper frame 12 is also a heat-insulating profile made of an extruded aluminum alloy profile for the outdoor side profile 26 and the indoor side profile 27, and a resin bridge material 28 connecting the outdoor side profile 26 and the indoor side profile 27. However, the upper frame 12 is not provided with the packing 3 like the lower frame 2.

[0012] Initially, the bridge material 7 of the lower frame 2 has its longitudinal end surfaces in contact with the sealant 8 on the inner peripheral side surface of the vertical frame 1 together with the outdoor side profile 5 and the indoor side profile 6 (see Fig. 4(a)). However, due to differences in the thermal expansion amounts of aluminum and resin, etc., the bridge material 7 may shrink over time. When the bridge material 7 of the lower frame 2 shrinks, the longitudinal end surfaces of the bridge material 7 separate from the sealant 8 on the inner peripheral side surface of the vertical frame 1, creating a gap 29 (see Fig. 5(a)). If no countermeasures are taken, rainwater that has entered the upper surface of the lower frame 2 may flow down through the gap 29 and penetrate into the building body. As shown in Figs. 5(a) and 5(b), in this building material for the opening, a packing 3 is provided on the outer peripheral side of the longitudinal end of the lower frame 2, and the packing 3 is in pressure contact with the bridge material 7 exposed from the separation part 19 between the outdoor side profile 5 and the indoor side profile 6. Also, the packing 3 closes the separation part 19 between the outdoor side profile 5 and the indoor side profile 6, and the longitudinal end surface of the packing 3 is in contact with the sealant 8 on the inner peripheral side surface of the vertical frame 1. Therefore, even if the bridge material 7 shrinks and a gap 29 is created between the longitudinal end surface of the bridge material 7 and the sealant 8 on the inner peripheral side surface of the vertical frame 1, the gap 29 is blocked by the packing 3 on the outer peripheral side, so leakage to the building body 30 side can be prevented. Moreover, this building material for the opening has a pressing material 21 that presses the packing 3 from the outer peripheral side, and the pressing material 21 crushes the packing 3. Thus, the gap 29 formed by the shrinkage of the bridge material 7 can be stably blocked, and leakage to the building body 30 can be reliably prevented.

[0013] As shown in Fig. 6, the packing 3 can be formed by being divided into two layers vertically. The upper packing 3a can be adhered to the outer peripheral side surface of the lower frame 2 with a double-sided tape or the like, and the lower packing 3b can be adhered to the upper surface of the pressing material 21 with a double-sided tape or the like. Also, the packing 3 and the pressing member 21 can be provided on the inner peripheral side (upper surface side) of the lower frame 2 instead of the outer peripheral side of the lower frame 2. At this time, the packing 3 and the pressing member 21 can be hidden by a resin cover 31 (see FIG. 1) attached to the upper surface of the lower frame 2 or a stopper part 32 (see FIG. 2).

[0014] Figs. 7 to 10 show a second embodiment of the opening building material of the present invention. As shown in Figs. 7 to 9, in the opening building material of the present embodiment, instead of providing the packing 3 as a water stop material on the inner peripheral sides of both longitudinal ends of the lower frame 2, a wet sealant (amorphous sealant) 4 is applied. As shown in Fig. 7, the sealant 4 is adhered across the indoor-side end of the inner peripheral side surface (upper surface) of the outdoor-side profile 5, the inner peripheral side surface of the bridge member 7, and the outdoor-side end of the inner peripheral side surface of the indoor-side profile 6. Further, as shown in Fig. 8, the sealant 4 is provided at a predetermined length (for example, about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it abuts against the sealer 8 of the vertical frame 1.

[0015] Initially, as shown in Fig. 10(a), the longitudinal end surfaces of the bridge member 7 together with the outdoor-side profile 5 and the indoor-side profile 6 abut against the sealer 8 of the vertical frame 1. As described above, the sealant 4 is adhered across the inner peripheral side surfaces (upper surfaces) of the outdoor-side profile 5, the bridge member 7, and the indoor-side profile 6, and the longitudinal end portions thereof are adhered to the sealer 8 of the vertical frame 1. Fig. 10(b) shows a state in which the bridge member 7 has shrunk and a gap 29 has occurred between the longitudinal end surface of the bridge member 7 and the sealer 8 of the vertical frame 1. Even when the bridge member 7 shrinks in this way, the sealant 4 is maintained in a state of being adhered to the sealer 8, and since the gap 29 between the bridge member 7 and the sealer 8 is blocked by the sealant 4 on the inner peripheral side, it is possible to prevent water leakage to the building body 30 side.

[0016] Figs. 11 to 14 show a third embodiment of the opening building material of the present invention. As shown in Figs. 11 to 13, the opening building material of this embodiment is provided with a sealing material 4 as a waterstop material on the outer peripheral side of the lower frame 2. As shown in Fig. 11, the sealing material 4 is adhered across the indoor-side end of the outer peripheral side surface (lower surface) of the outdoor-side profile 5, the outer peripheral side surface of the bridge material 7, and the outdoor-side end of the outer peripheral side surface of the indoor-side profile 6. Further, as shown in Fig. 12, the sealing material 4 is provided at a predetermined length (for example, about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it abuts against the sealer 8 of the vertical frame 1.

[0017] Initially, as shown in Fig. 14(a), the longitudinal end faces of the bridge material 7 together with the outdoor-side profile 5 and the indoor-side profile 6 abut against the sealer 8 of the vertical frame 1. As described above, the sealing material 4 is adhered across the outer peripheral side surfaces (lower surfaces) of the outdoor-side profile 5, the bridge material 7, and the indoor-side profile 6, and the longitudinal end portions are adhered to the sealer 8 of the vertical frame 1. Fig. 14(b) shows a state in which the bridge material 7 has shrunk and a gap 29 has occurred between the longitudinal end face of the bridge material 7 and the sealer 8 of the vertical frame 1. Even when the bridge material 7 shrinks in this way, the sealing material 4 is maintained in an adhered state with the sealer 8, and since the gap 29 between the bridge material 7 and the sealer 8 is blocked by the sealing material 4 on the outer peripheral side, it is possible to prevent water leakage to the building body 30 side.

[0018] As described above, this opening building material (first to third embodiments) includes a vertical frame 1, a horizontal frame (lower frame) 2, and waterstops (packing, sealing material) 3 and 4. The horizontal frame 2 is composed of an outdoor-side profile 5, an indoor-side profile 6, and a bridge material 7 that connects the outdoor-side profile 5 and the indoor-side profile 6. The longitudinal end face abuts against the inner peripheral side surface of the vertical frame 1 via a sealer 8, and the outdoor-side profile 5 and the indoor-side profile 6 are screwed to the vertical frame 1. The waterstops 3 and 4 are provided in the longitudinal direction of the horizontal frame 2 from the position where they abut against the sealer 8 on the outer peripheral side or the inner peripheral side of the horizontal frame 2, and abut against the sealer 8, the outdoor-side profile 5, the indoor-side profile 6, and the bridge material 7. When the bridge material 7 shrinks, the gap 29 between the longitudinal end face of the bridge material 7 and the sealer 8 is blocked by the waterstops 3 and 4, so that heat insulation performance can be obtained, and even when the bridge material 7 shrinks, water leakage to the building body 30 can be prevented by the waterstops 3 and 4, which is convenient to use. In the opening building material of the first embodiment, since the waterstop 3 is packing and there is a pressing material 21 that presses the packing 3 from the outer peripheral side or the inner peripheral side of the horizontal frame 2, the gap 29 formed by the shrinkage of the bridge material 7 can be stably blocked, and water leakage to the building body 30 can be reliably prevented. In the opening building materials of the second and third embodiments, since the waterstop 4 is an amorphous sealing material, water leakage to the building body 30 can be prevented only by applying the amorphous sealing material 4 to a predetermined position of the frame 10, and the cost is low. Moreover, in this opening building material (first to third embodiments), since the waterstops 3 and 4 are provided in a region of a predetermined length in the longitudinal direction of the horizontal frame 2 from the sealer 8, the gap 29 caused by the shrinkage of the bridge material 7 can be reliably blocked by the waterstops 3 and 4, and moreover, the cost can be suppressed compared with the case of providing it over the entire length in the longitudinal direction of the horizontal frame 2.

[0019] The present invention is not limited to the embodiments described above. The cross-sectional shapes of the outdoor-side member and the indoor-side member can be appropriately changed. The shape and material of the waterstop material can be appropriately changed. The waterstop material only needs to be provided so as to fill the gap formed when the bridge material shrinks, and the specific position and mounting method can be appropriately changed. The vertical frame may be square, and the horizontal frame may be seamless. The present invention can be applied not only to sliding windows but also to flush windows, sliding-out windows, doors for entrances and exits, curtain walls, and all other building materials for openings.
