As shown in FIG. 3, the storage of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is in a so-called horizontal winning state. ing. As shown in FIG. 5, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are notched so as to reach the projecting piece 28 from the longitudinal end portion to a position separated from the flange 17 toward the inner peripheral side. 34, and the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are cut at the longitudinal ends at right angles, and the cut ends are formed inside the indoor side 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 and 14 of the collar frames 5 and 6 do not need to be cut out, and the number of processing steps can be reduced.
FIG. 6 shows another example of processing of the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. As shown in FIG. 6 (b), the protruding piece 28 has a length in the indoor / outdoor direction of the tip 28a formed of a soft resin longer than that in FIG. 5, and also shown in FIG. 6 (a). As described above, the notch 34 of the projecting piece 28 at the end in the longitudinal direction is reduced, and the projecting piece 28 is located at a position adjacent to the outer peripheral side of the projecting piece 28 of the indoor side resin frame parts 13, 14 of the collar frames 5, 6. An incision 36 is provided in FIG. Since the notches 36 are provided in the protruding piece 28 as described above, only the left and right end portions of the protruding piece 28 are deformed when the shoji 2 is closed as shown in FIG. There is no problem in closing the shoji 2 without excising the portion that overlaps with the scissors 17.

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 on the indoor 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 that protrudes to the outdoor side, and the protruding piece 28 is located on the inner peripheral side with respect to the flanges 15, 16, and 17 of the shoji 2. , 17 are hidden by the indoor resin frame portions 11, 12, 13, and 14, so that the appearance of the interior is good. Furthermore, since the gap 32 is provided between the tip of the protruding piece 28 and the glass surface 31 of the shoji 2, as shown in FIG. 1, the dew condensation water 37 generated on the upper collar 15, the glass surface 31, etc. As indicated by arrows 38a and 38b in the figure, the projecting piece 28 is allowed to flow without damming, and dew condensation does not stay on the upper surface of the lower frame 4 (the inner peripheral side surface 35 of the indoor resin frame portion 12). . The condensed water that flows down stays on the tight material 25 that seals the lower frame 4 and the lower rod 16, but if the shoji 2 is opened, it is drained to the outside, and the shoji 2 is not opened. Over time it will not evaporate.
Further, the opening building material is provided between the flanges 15, 16, and 17 of the shoji 2 and the indoor resin frame portions 11, 12, 13, and 14 by the protruding pieces 28 of the indoor resin frame portions 11, 12, 13, and 14. Since the entrance 33a of the space 33 has a zigzag shape, the outdoor cold air transmitted through the aluminum cages 15, 16, and 17 is formed in the space 33. The heat insulation performance is improved because it is difficult to transmit cold air to the living space. In addition, rainwater spouted over the tight material 25 during a storm is less likely to leak into the room due to a decrease in kinetic energy as it rises in the space 33, so that watertightness is also improved.
Further, the tip portion 28a of the protruding piece 28 of the indoor side resin frame portions 11, 12, 13, 14 is formed of soft resin, so that the glass 19 is deformed indoors during a storm, or the shoji 2 is closed wildly. Even if the protruding piece 28 comes into contact with the glass surface 31 at the time, the glass 19 can be prevented from being damaged, and the above-mentioned drainage, heat insulation and watertight performance can be maintained as they are.
Since the projecting piece 28 is separated from the inner peripheral edge 30 of the indoor side wall of the flanges 15, 16, and 17 to the inner peripheral side by about 5 to 10 mm, the shoji 2 starts to open as shown by a two-dot chain line in FIG. Even when the shoji 2 slides to the door end side, the protruding piece 28 does not interfere with the heel 17 on the door bottom side, and the opening and closing of the shoji 2 is not hindered.
Furthermore, this building material for the opening portion not only shows the scissors 15, 16, 17 of the shoji 2 from the inside, but also seals with different textures and colors between the indoor resin frame portions 11, 12, 13, 14 and the glass 19. 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. In the present embodiment, the shapes of the indoor side resin frame portions 13 and 14 of the collar frames 5 and 6 are different from those of the first embodiment. The indoor side resin frame parts 13 and 14 of the eaves frames 5 and 6 are inclined so that the inner peripheral side surface 42 is positioned on the inner peripheral side as it goes to the outdoor side. As for the indoor side resin frame part 14 of the frame 6 on the door end side, the outer peripheral side part 14a is also used in the first embodiment.
Thus, by inclining the inner peripheral side surface 42, the finding dimension A of the indoor side ends of the collar frames 5 and 6 can be reduced, and the interior design is further improved. Further, the upper and lower frames 3, 4 and the eaves frames 5, 6 can have a common finding dimension A at the indoor side end. Furthermore, since the corner part 43 between the inner peripheral side surface 42 of the gutter frames 5 and 6 and the glass surface 31 becomes an obtuse angle, the wiping and cleaning of the corner part 43 is facilitated as compared with the case where it is a right angle.
Also in this embodiment, the storage of the end portions of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is the same as in the first embodiment. Even if the inner peripheral side surfaces 42 of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are inclined by setting the winning state, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. Is easy to process.

8 and 9 show a third embodiment of the opening part building material of the present invention. The thing of this embodiment fixes the shoji 2 in the frame 1 with the fixing tool (illustration omitted), and makes it the FIX window. The frame 1 and the shoji 2 are the same as those in the first embodiment.
As shown in FIG. 8, a gap closing material 44 made of rubber or soft resin is placed in the gap 32 between the tip of the protruding piece 28 of the indoor side resin frame 12 of the lower frame 4 and the glass surface 31. Inserted from the circumferential side. Thereby, in the FIX window in which the shoji 2 cannot be opened and closed, foreign matter may fall into the gap 32 between the tip of the protruding piece 28 of the indoor side resin frame 12 of the lower frame 4 and the glass surface 31, making it difficult to take out. It is possible to prevent the design from deteriorating. Moreover, as shown in FIG. 9, since there is a gap 32 between the tip of the protruding piece 28 of the indoor side resin frame portions 13, 14 of the eaves frames 5, 6 and the glass surface 31, it occurred on the glass surface 31. After the condensed water falls on the gap plugging material 44, it can be drained through the gap 32 (see arrow 45 in the figure), and the condensed water can be prevented from staying on the upper surface of the indoor resin frame portion 12. .
When importance is attached to watertightness or airtightness, the gap 32 between the tips of the protruding pieces 28 of the four-side indoor resin frame portions 11, 12, 13, 14 and the glass surface 31 may be closed with a gap closing material 44. it can. Even in that case, by leaving the gap 32 between the protruding piece 28 and the glass surface 31 at the lower end of at least one of the frame 5 or 6, the condensed water generated on the glass surface 31 can be removed from the gap 32. Can be drained through.
