[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figure 1 shows one embodiment of the building material for openings of the present invention. This building material for openings is applied to sliding windows for residential use, and comprises a frame 8 attached to an opening in the building structure, and an outer screen and an inner screen (not shown) that are housed within the frame 8 in a sliding manner so that they can be opened and closed freely. The frame 8 is composed of an upper frame, a lower frame 3, and left and right vertical frames 9, which are framed in a rectangular shape. The outer screen and the inner screen are constructed by assembling an upper frame, a lower frame, a door end frame, and a joint frame, and fitting glass inside the frame.

[0008] As shown in Figure 1, the lower frame 3 has an exterior shape member 1 and an interior shape member 2 made of aluminum alloy extrusions, and a bridge member 4 connecting the exterior shape member 1 and the interior shape member 2. The interior shape member 2 is divided into an upper interior shape member 2a and a lower interior shape member 2b above and below. Tapping holes 10 are provided in the exterior shape member 1, the upper interior shape member 2a, and the lower interior shape member 2b. The bridge member 4 is made of a material with insulating properties, and blocks heat transfer between the exterior shape member 1 and the interior shape member 2 (upper interior shape member 2a).

[0009] The lower frame 3 is connected and fixed to the vertical frame 9 by abutting its longitudinal end face against the inner side surface of the vertical frame 9 via a sealer (not shown), and screwing screws 11 inserted from the side of the vertical frame 9 into tapping holes 10 in the exterior shape member 1, the upper interior shape member 2a, and the lower interior shape member 2b.

[0010] As described below, the exterior exterior shape member 1 and the upper interior exterior shape member 2a are originally molded in a connected state as a single piece, and are separated below the bridge material 4 after the bridge material 4 is poured into the mold. In this bottom frame 3, a packing 6 is provided between the bridge material 4 exposed from the separation part 5 between the outdoor exterior shape material 1 and the upper indoor interior shape material 2a, and the lower indoor interior shape material 2b. As shown in Fig. 2-2(d), the packing 6 is rod-shaped with a rectangular cross section before installation, and as shown in Fig. 2-2(e), when installed, it is crushed in the indoor / outdoor direction and in the vertical direction, sealing the separation part 5 between the outdoor exterior shape material 1 and the upper indoor interior shape material 2a and pressing against the bridge material 4. The packing 6 is provided over the entire length of the bottom frame 3, and the longitudinal end face of the packing 6 abuts against the inner peripheral side surface of the vertical frame 9 (strictly speaking, the sealer attached to the inner peripheral side surface of the vertical frame 9).

[0011] As shown in FIG. 1, the lower interior shape member 2b has a hollow portion 12 with a substantially rectangular cross section, and protrusions 13, 13 that engage with the upper interior shape member 2a are provided on the upper surface at intervals in the indoor and outdoor directions. The exterior wall of the hollow portion 12 hangs down, and abutment piece 15 that abuts against the structure 14 is provided at its lower end. Furthermore, the lower interior shape member 2b is provided with a water receiving piece 7 at a position spaced upward from the abutment piece 15. The water receiving piece 7 is located below the separation part 5 between the exterior shape member 1 and the upper interior shape member 2a, and the exterior part is inclined upward. By providing the water receiving piece 7 in this way, even if water leaks from the separation part 5 between the exterior shape member 1 and the upper interior shape member 2a, the water receiving piece 7 receives the water, so the water does not reach the structure 14.

[0012] The upper frame and vertical frame 9 are also heat-insulating members that connect the aluminum exterior and interior shapes with a resin bridge material, just like the lower frame 3. However, the upper frame and vertical frame 9 do not have the gasket 6 or water receiving piece 7 that the lower frame 3 has.

[0013] Next, the manufacturing procedure of this opening building material will be explained. First, as shown in Fig. 2-1(a), resin (e.g. polyurethane resin) 18, which is the material of the bridge material 4, is injected into the bridge material injection groove 17 formed in the integrally molded shape 16 in which the exterior shape 1 and the upper interior shape 2a are connected together. After the resin 18 has hardened, as shown in Fig. 2-1(b), the corners on the outer periphery of the bridge material injection groove 17 are cut from the inside of the room with a tool 19, and the outside shape 1 and the upper inside shape 2a are separated. At this time, part of the bridge material 4 is also cut and removed to form an inside corner 20 (see Fig. 2-1(c)). Thereafter, as shown in Figure 2-1(c), the lower frame 3, which connects the exterior shape member 1 and the upper interior shape member 2a with bridging material 4, is abutted at its longitudinal end face against the inner peripheral side surface of the vertical frame 9 to which a sealer has been applied, and screws 11 inserted into the vertical frame 9 from the side are screwed into tapping holes 10, thereby connecting and fixing to the vertical frame 9. As with the lower frame 3, the upper frame is also abutted at its longitudinal end face against the inner peripheral side surface of the vertical frame 9 via the sealer, and connected and fixed to the vertical frame 9 with screws screwed into the tapping holes of the upper frame. Next, as shown in Figure 2-2(d), a gasket 6 is attached to the exterior surface of the lower room inner profile 2b using double-sided tape or the like, and the protrusions 13, 13 on the upper surface are engaged between the tapping hole 10 and the hanging piece 21 of the upper room inner profile 2a, and the lower room inner profile 2b is attached below the upper room inner profile 2a. Then, as shown in Figure 2-2 (e), with the corners of the packing 6 fitted into the inside corners 20 of the bridge material 4, the packing 6 is crushed in the indoor / outdoor directions and in the vertical directions, and the packing 6 closes the separation part 5 between the outdoor side shape member 1 and the upper indoor side shape member 2a, and the packing 6 is pressed against the bridge material 4 exposed from the separation part 5. After that, the screw 11 inserted into the vertical frame 9 from the side is screwed into the tapping hole 10 of the lower indoor side shape member 2b, and the lower indoor side shape member 2b is connected and fixed to the vertical frame 9. The frame 8 formed as described above is attached to the opening in the main frame in the same way as a normal sash, and the outer and inner sashes are fitted between the rails 22 of the upper and lower frames 3 using a buckle.

[0014] In sashes that use insulated profiles, the bridge material can shrink over time due to factors such as the difference in the amount of thermal expansion between aluminum and resin.When the bridge material of the sash frame shrinks, the end face of the bridge material separates from the sealer on the inner side of the vertical frame, creating a gap.Rainwater that has penetrated the top of the sash frame can flow down through the gap and penetrate into the main structure. As shown in Figure 1, in this opening building material, a gasket 6 is pressed against the bridge material 4 exposed from the separation part 5 between the exterior shape member 1 of the lower frame 3 and the upper interior shape member 2a, and the gasket 6 seals the separation part 5 between the exterior shape member 1 and the upper interior shape member 2a. The longitudinal end face of the gasket 6 abuts against the sealer on the inner side face of the vertical frame 9. Therefore, even if the bridge material 4 shrinks and a gap occurs between the longitudinal end face of the bridge material 4 and the sealer on the inner side face of the vertical frame 9, water can be prevented from leaking through the gap into the main body 14. Furthermore, this opening building material is provided with a water receiving piece 7 on the lower room side shape 2b of the sill 3, so that even if water should exceed the packing 6 and fall below, the water will be received by the water receiving piece 7 and will not wet the structure 14. This allows this opening building material to reliably prevent water from leaking into the structure 14.

[0015] The packing 6 can be attached not by adhering it to the outdoor side surface of the lower room inside shape member 2b with double-sided tape or the like, but by providing a holder part that opens toward the outdoor side on the packing attachment surface of the lower room inside shape member 2b and fitting the packing 6 into the holder part. This makes it easy and accurate to attach the packing 6, improving workability.

[0016] Fig. 3 shows another embodiment of the building material for openings of the present invention. This embodiment is different in that the water receiving piece 7 of the sill 3 is provided on the exterior shape member 1. The water receiving piece 7 is provided slanting upward toward the interior so as to be continuous with the lower wall 24 of the hollow portion 23 of the exterior shape member 1, and the tip portion is further bent upward. The water receiving piece 7 extends to below the separation part 5 between the exterior shape member 1 and the upper interior shape member 2a.

[0017] In the opening building material of this embodiment, as in the previously described embodiment, even if water flows down beyond the packing 6 when the bridge material 4 of the sill 3 shrinks, the water is received by the water receiving piece 7 and does not wet the structure 14. Furthermore, if drainage holes (not shown) are formed in the indoor wall 25 and the outdoor wall 26 of the hollow portion 23 of the outdoor exterior shape material 1, the water that has accumulated on the water receiving piece 7 can be drained to the outside.

[0018] As described above, this opening building material comprises an exterior shape member 1, an interior shape member 2, and a bridge material 4 connecting the exterior shape member 1 and the interior shape member 2. The exterior shape member 1 and the interior shape member (upper interior shape member) 2a are connected when the bridge material 4 is poured into the mold and then separated below the bridge material 4. A gasket 6 is provided between the bridge material 4 exposed from the separated portion 5 and the interior shape member (lower interior shape member) 2b, thereby providing insulating performance and, even when the bridge material 4 shrinks, the gasket 6 prevents water leakage into the main body 14, making it easy to use. The gasket 6 may be provided only at both longitudinal ends of the lower frame 3, but providing it over the entire length of the lower frame 3 allows the gasket 6 to be installed more stably and prevents water leakage from around the bridge material 4 over the entire length of the lower frame 3.

[0019] In addition, this opening building material comprises an exterior shape member 1, an upper interior shape member 2a, a lower interior shape member 2b, and a bridge material 4 connecting the exterior shape member 1 and the upper interior shape member 2a. The exterior shape member 1 and the upper interior shape member 2a are connected while the bridge material 4 is poured and then separated below the bridge material 4. The lower interior shape member 2b is attached to the separated upper interior shape member 2a. The exterior shape member 1 or the lower interior shape member 2b has a water receiving piece 7 that receives water that leaks from between the exterior shape member 1 and the upper interior shape member 2a, thereby providing insulating performance and, even when the bridge material 4 shrinks, the water receiving piece 7 prevents water from leaking into the main body 14, making it easy to use. Furthermore, this opening building material has a gasket 6 abutting the bridge material 4 exposed from the separation part 5 between the exterior shape material 1 and the upper interior shape material 2a. Therefore, even if the bridge material 4 shrinks and a gap occurs between it and the vertical frame 9, the gasket 6 can prevent water from leaking through the gap, thereby more reliably preventing water from leaking into the main body 14.

[0020] The present invention is not limited to the above-described embodiment. The water receiving piece does not necessarily have to be provided. The cross-sectional shapes of the exterior and interior shapes can be changed as appropriate. The interior shape does not necessarily have to be divided into an upper interior shape and a lower interior shape. The shape and material of the packing can be changed as appropriate. The packing only needs to be provided so that water does not leak to the frame when the bridge material shrinks, and the specific position and installation method are not important. The present invention is not limited to sliding windows, but can be applied to all opening building materials such as fixed windows, sliding windows, entrance doors, and kitchen doors.
