As shown in FIGS. 1 and 2, the frame 1 comprises an upper frame 3, a lower frame 4 and vertical frames 5 and 6. As shown in FIG. The upper frame 3, the lower frame 4, and the vertical frames 5, 6 are metal frame portions 7, 8, 9, 10 made of extruded aluminum alloy profiles, and the interior side of the metal frame portions 7, 8, 9, 10, respectively. It is composed of interior-side resin frame portions 11, 12, 13, and 14 made of extruded resin members attached to the inner peripheral portion.
The shoji 2 is composed of an upper frame 15, a lower frame 16, and vertical frames 17, 17 made of extruded aluminum alloy members, which are assembled in a frame. It is fitted through Grechan 20. The shoji 2 is connected to the frame 1 by friction stays 21a and 21b arranged between the metal frame portion 7 and the upper frame 15 of the upper frame 3 and between the metal frame portion 8 and the lower frame 16 of the lower frame 4, As shown in FIG. 4, it is designed to open by rotating 90° around the vertical axis while sliding toward the door. The opening/closing operation of the shoji 2 is performed by operating an operator handle 22 provided on the indoor side surface of the indoor-side resin frame portion 12 of the lower frame 4, as shown in FIG.

As shown in FIGS. 1 and 2, each of the metal frames 7, 8, 9, and 10 has a tight material holder 23 protruding inward from the intermediate portion in the indoor/outdoor direction. A tight material 25 is attached facing outward. The tight material 25 is in contact with the outer peripheral edges of the frames 15, 16 and 17 of the shoji 2 on the indoor side.

Each of the indoor-side resin frame portions 11, 12, 13, and 14 is provided on the indoor side of the tight material holder 23 of the metal frame portions 7, 8, 9, and 10 so as to protrude toward the inner peripheral side. It covers the part of the anchor. Each of the indoor-side resin frame portions 11, 12, 13, and 14 includes a hollow portion 26 having a rectangular cross section, an angle portion 27 provided by extending an outer peripheral wall of the hollow portion 26 toward the indoor side, and an inner wall of the hollow portion 26. It has a protruding piece 28 provided by extending the wall on the peripheral side to the outside of the room, and a plurality of locking claws 29a, 29b, 29c that are locked to the metal frame portions 7, 8, 9, 10. As shown in FIG. The projecting piece 28 is positioned about 5 to 10 mm away from the inner peripheral edge 30 of the indoor side wall of the frame 15, 16, 17 on the inner peripheral side, and the tip of the projecting piece 28 and the glass surface 31 of the shoji 2 are spaced apart from each other. A gap 32 of about 3 mm is provided. A tip portion 28a of the projecting piece 28 is made of a soft resin. This soft resin portion is integrally formed with other hard resin portions by extrusion molding (so-called two-color molding).
By providing such indoor resin frame portions 11, 12, 13, 14 on the inner peripheral portion of the indoor side of the frame 1, the frames 15, 16, 17 of the shoji 2 are hidden from being seen from the indoor side. A space 33 having a narrow frontage and a large depth is formed between the frames 15, 16, 17 of the shoji 2 and the resin frames 11, 12, 13, 14 on the indoor side.

Of the four indoor resin frame portions 11, 12, 13, and 14, the indoor resin frame portion 12 of the lower frame 4 is divided into an outer peripheral side portion 12a and an inner peripheral side portion 12b as shown in FIG. formed. By splitting the indoor-side resin frame portion 12 of the lower frame 4 in this way, it is possible to perform processing for attaching the operator handle 22 and installing an interlocking mechanism for transmitting the movement of the operator handle 22 to the friction stay 21b. Easy to do.
Further, as shown in FIG. 2, the indoor resin frame portion 14 of the vertical frame 6 on the door end side is also formed by being divided into an outer peripheral side portion 14a and an inner peripheral side portion 14b. Instead of the operator handle 22, this opening building material can also attach a cam latch handle to the indoor side surface of the door frame 17 of the shoji 2. In that case, the indoor resin frame portion 14 of the vertical frame 6 on the door end side Although it is necessary to perform notch processing or the like on the inner side, the processing can be easily performed by dividing the interior-side resin frame portion 14 in this way.

Each indoor resin frame portion 11, 12, 13, 14 is attached in advance to each metal frame portion 7, 8, 9, 10 from the inner peripheral side, and then the metal frame portions 7, 8 of the upper and lower frames 3, 4 are mounted. The longitudinal end faces of the vertical frames 5 and 6 are brought into contact with the inner peripheral side surfaces of the metal frame portions 9 and 10 of the vertical frames 5 and 6, and the screws inserted from the side are tapped on the metal frame portions 7 and 8 of the upper and lower frames 3 and 4. The upper and lower frames 3 and 4 and the vertical frames 5 and 6 are framed by being screwed into the holes.
As shown in FIG. 3, the ends of the indoor-side resin frame portions 13, 14 of the vertical frames 5, 6 and the indoor-side resin frame portions 11, 12 of the upper and lower frames 3, 4 are fitted in a so-called horizontal winning state. ing. As shown in FIG. 5, the ends of the indoor-side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are notches that reach the projecting piece 28 from the longitudinal end to a position spaced from the vertical frame 17 to the inner peripheral side. 34 is provided, and the longitudinal ends of the indoor resin frame portions 13 and 14 of the vertical frames 5 and 6 are cut at right angles, and the cut ends are inserted into the indoor resin frame portions 11 and 12 of the upper and lower frames 3 and 4. It is in contact with the peripheral side surface 35 . Therefore, the protruding pieces 28 of the indoor-side resin frame portions 13, 14 of the vertical frames 5, 6 do not require notching, and the number of processing steps can be reduced.
FIG. 6 shows another example of processing of the end portions of the indoor resin frame portions 11 and 12 of the upper and lower frames 3 and 4. As shown in FIG. As shown in FIG. 6(b), the projecting piece 28 has a tip portion 28a made of soft resin whose length in the indoor and outdoor direction is longer than that in FIG. , the notches 34 of the protruding pieces 28 at the ends in the longitudinal direction are made small, and the protruding pieces 28 are formed at positions adjacent to the outer peripheral side of the protruding pieces 28 of the indoor-side resin frame portions 13, 14 of the vertical frames 5, 6. A notch 36 is provided in the . By providing the notch 36 in the projecting piece 28 in this manner, only the left and right ends of the projecting piece 28 are deformed when the shoji 2 is closed, as shown in FIG. There is no problem in closing the shoji 2 even if the part overlapping with the vertical frame 17 is not cut off.

As described above, this opening building material is provided with the indoor resin frame portions 11, 12, 13, and 14 on the inner peripheral portion of the room side of the frame 1, and the indoor resin frame portions 11, 12, 13, and 14 are The inner peripheral side surface 35 has a protruding piece 28 protruding to the outside of the room, and the protruding piece 28 is located on the inner peripheral side of the frames 15, 16, 17 of the shoji 2, so that the frames 15, 16 of the shoji 2 , 17 are hidden by the indoor-side resin frame portions 11, 12, 13, 14, the interior appearance is good. Furthermore, by providing a gap 32 between the tip of the projecting piece 28 and the glass surface 31 of the shoji 2, as shown in FIG. As indicated by arrows 38a and 38b in the figure, the condensed water is allowed to flow down without being dammed by the protruding piece 28, and the condensed water does not stay on the upper surface of the lower frame 4 (the inner peripheral side surface 35 of the indoor-side resin frame portion 12). . The condensed water that has flowed down stays on the tight material 25 that seals the lower frame 4 and the lower frame 16, but if the shoji 2 is opened, it will be drained outside the room, and even if the shoji 2 is not opened. It will evaporate over time.
Furthermore, the projecting pieces 28 of the indoor-side resin frames 11, 12, 13, and 14 allow the opening building material to move between the frames 15, 16, and 17 of the shoji 2 and the indoor-side resin frames 11, 12, 13, and 14. A space 33 with a narrow frontage and a deep depth is provided in the space 33, and the entrance portion 33a of the space 33 has a zigzag shape. Insulation performance is improved because cold air stays in the air and makes it difficult for cold air to reach the living space. In addition, the rainwater that gushes out over the tight material 25 during a storm has a lower kinetic energy as it rises in the space 33, and water is less likely to leak into the room, thereby improving the watertightness.
In addition, since the tips 28a of the protruding pieces 28 of the indoor-side resin frames 11, 12, 13, and 14 are made of a soft resin, the glass 19 is deformed indoors during a storm, and the shoji 2 is not violently closed. Even if the protruding piece 28 comes into contact with the glass surface 31, the glass 19 can be prevented from being broken, and the above-described drainage, heat insulation, and watertightness performances can be maintained as they are.
Since the protruding piece 28 is separated from the inner peripheral edge 30 of the indoor side wall of the frame 15, 16, 17 by about 5 to 10 mm to the inner peripheral side, the shoji 2 starts to open as shown by the two-dot chain line in FIG. Even if the shoji 2 slides to the door tip side, the projecting piece 28 does not interfere with the vertical frame 17 on the door bottom side, and the opening and closing of the shoji 2 is not hindered.
Furthermore, in this opening building material, not only are the frames 15, 16, 17 of the shoji 2 invisible when viewed from the inside, but also seals with different textures and colors between the indoor resin frames 11, 12, 13, 14 and the glass 19 are provided. Since there is no material, the interior design can be further improved.

FIG. 7 shows a second embodiment of the opening building material of the present invention. This embodiment differs from the first embodiment in the shape of the indoor-side resin frame portions 13, 14 of the vertical frames 5, 6. As shown in FIG. The indoor-side resin frame portions 13, 14 of the vertical frames 5, 6 are inclined such that the inner peripheral side surface 42 is located on the inner peripheral side as it goes toward the outdoor side. As for the indoor resin frame portion 14 of the vertical frame 6 on the side of the door, the outer peripheral side portion 14a is also used in the first embodiment.
By inclining the inner peripheral side surface 42 in this manner, the apparent dimension A of the indoor-side end portions of the vertical frames 5 and 6 can be reduced, and the interior design is further improved. Further, the vertical frames 3, 4 and the vertical frames 5, 6 can share the nominal dimension A of the room-side end. Furthermore, since the inside corner 43 between the inner peripheral side surface 42 of the vertical frames 5 and 6 and the glass surface 31 has an obtuse angle, the inside corner 43 can be easily wiped clean compared to the case where the angle is right.
Also in the present embodiment, the ends of the indoor resin frame portions 13 and 14 of the vertical frames 5 and 6 and the indoor resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are arranged horizontally as in the first embodiment. By setting the winning state, even if the inner peripheral side surfaces 42 of the indoor resin frame portions 13 and 14 of the vertical frames 5 and 6 are inclined, the end portions of the indoor resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are maintained. There is no need to cut diagonally, and processing is easy.

8 and 9 show a third embodiment of the opening building material of the present invention. In this embodiment, a shoji 2 is fixed in a frame 1 with a fixture (not shown) to form a FIX window. A frame 1 and a shoji 2 are common to those of the first embodiment.
As shown in FIG. 8, a gap closing member 44 made of rubber or soft resin is placed in the gap 32 between the tip of the projecting piece 28 of the indoor-side resin frame portion 12 of the lower frame 4 and the glass surface 31. It is installed by inserting it from the peripheral side. As a result, in a FIX window in which the shoji 2 cannot be opened and closed, foreign matter falls into the gap 32 between the tip of the projecting piece 28 of the indoor-side resin frame portion 12 of the lower frame 4 and the glass surface 31, making it difficult to take out. , the design can be prevented from deteriorating. Moreover, as shown in FIG. 9, since there is a gap 32 between the glass surface 31 and the tips of the protruding pieces 28 of the indoor-side resin frame portions 13, 14 of the vertical frames 5, 6, Condensed water can be drained through this gap 32 after dropping onto the gap plugging material 44 (see arrow 45 in the figure), thereby preventing the condensed water from remaining on the upper surface of the indoor resin frame 12. .
When emphasizing watertightness and airtightness, gaps 32 between the tips of projecting pieces 28 of the four indoor-side resin frames 11, 12, 13, and 14 and the glass surface 31 can be closed with a gap closing material 44. can. Even in that case, by leaving a gap 32 between the projecting piece 28 and the glass surface 31 at the lower end of at least one of the vertical frames 5 or 6, dew condensation water generated on the glass surface 31 can be removed from the gap 32. can be drained through
