  As is clear from the figure, the skeleton B of the present embodiment is provided with the heat insulating material Bb and the exterior sheet material Bc in the portion on the outdoor side of the structural material Ba. The heat insulating material Bb is arranged so as to cover the structural material Ba from the outdoor side without a gap. The exterior sheet material Bc is a waterproof member that is directly provided on the outer surface of the heat insulating material Bb, and is disposed on the entire surface of the body B that faces the outside of the room. The exterior sheet material Bc needs to be waterproof at least from the outdoor side to the indoor side, but a material having moisture permeability from the indoor side to the outdoor side can also be applied.

  Further, the skeleton B is provided with an outer wall material C so as to cover the exterior sheet material Bc. The outer wall material C is a thick plate member provided at a position where a predetermined gap is secured between the outer sheet material Bc and the surface of the exterior sheet material Bc (hereinafter referred to as the outer surface Bd of the body B). A ventilation layer D is formed between them. As the outer wall material C, it is preferable to apply an appropriate material having no water permeability, such as a cement board or a metal plate. A rectangular window hole Ca is secured in a portion of the outer wall material C corresponding to the opening H of the body B.

  For the above-mentioned building, the frame body 10 is installed in the opening H of the skeleton B with the extended end portion located on the outdoor side protruding from the outer surface Bd of the skeleton body B. The extended end surface of the frame 10 located on the outdoor side is arranged at a position substantially coincident with the outer surface Cb of the outer wall material C. Hereinafter, the waterproof structure between the opening H of the skeleton B and the frame 10, which is a characteristic part of the present invention, will be described in detail with reference to FIGS. 7 to 11 as appropriate.

  First, the waterproof sheet material 20 is arranged in each of the portions extending from the outer surface Bd of the skeleton B to the inner surface Ha of the opening H.

The plate thickness 30t of the water blocking member 30 is set to have a dimension larger than the gap between the prospective surface 11a of the upper frame 11 and the waterproof sheet member 20 provided in the opening H. In the present embodiment, separate water blocking members 30 are arranged on the left and right sides of the frame body 10. Each water blocking member 30 is a series of parts having a portion 30a extending vertically along the extending direction of the vertical frame 13 and a portion 30b extending along the extending direction of the upper frame 11. is there. Between the prospective surface 13a of the vertical frame 13 and the waterproof sheet material 20 provided in the opening H, the portion 30b of the water blocking material 30 is arranged over the entire length thereof. Between the prospective surface 11a of the upper frame 11 and the waterproof sheet material 20 provided in the opening H, the portion 30a of the water blocking material 30 is arranged so as to secure a gap between the extending end portions of each other. I am trying to set it up. The position in the prospective direction in which the water blocking member 30 is provided is set to a portion of the waterproof sheet material 20 provided in the opening H that is the most outdoor side. That is, the prospective surfaces 11a and 13a of the frames 11 and 13 and the waterproof sheet material 20 provided in the opening H are arranged so that the surface of the waterproofing material 30 that faces the outside of the room is at substantially the same position as the outer surface Bd of the skeleton B. A water blocking material 30 is arranged between the two.

  After the frame body 10 is installed in the opening H, the extending end portion of the above-described waterproof sheet material 20 located on the indoor side is folded back to the inner peripheral side, and covers the nail fin portions 11b, 12b, 13b, respectively. Is kept in a closed state. The nail fins 11b, 12b, 13b are subsequently covered with the frame G and are not visible from the outside.

  An upper draining member 40 is arranged at a portion of the outer surface Bd of the skeleton B which is the upper edge of the opening H. The upper draining member 40 is an extruded shape member formed of a metal such as an aluminum alloy, and has a substrate portion 41 and an upper frame cover portion 42. The substrate portion 41 has a rectangular plate shape and is formed to have a length substantially the same as the dimension along the longitudinal direction of the upper frame 11. The upper frame cover portion 42 is a portion that extends from one side edge portion of the substrate portion 41 so as to bend, and then extends so as to gradually curve toward a direction away from the base end portion.

  The upper draining member 40 is attached to the skeleton B in a state where the upper frame cover portion 42 projects outward from the upper edge portion of the opening H by screwing a screw J onto the skeleton B through the substrate portion 41. It is attached. The upper frame cover portion 42 of the upper draining member 40 attached to the skeleton B is in a state of covering the upper surface of the extending end portion of the upper frame 11 protruding from the skeleton B and the finding surface 11d facing the outdoor. An upper frame water stop material 50 is provided between the upper frame cover part 42 and the outer surface 11d of the upper frame 11 which faces the outside. The upper frame water blocking member 50 has elasticity and water blocking properties like a water blocking sponge like the water blocking member 30 described above, and is arranged at the entire length of the upper draining member 40. The substrate portion 41 of the upper draining member 40 extends upward beyond the waterproof sheet material 20 that covers a portion of the outer surface Bd of the skeleton B that serves as the upper edge of the opening H. A waterproof tape 60 is attached to the surface of the substrate portion 41 facing the outside of the room up to the outer surface Bd of the skeleton B. The waterproof tape 60 is a belt-shaped sheet material having a waterproof property, and is provided so as to cover a gap between the upper edge of the substrate portion 41 and the outer surface Bd of the skeleton B.

  End caps (passage forming members) 70 are attached to both ends of the upper draining member 40, respectively. As shown in FIG. 12, the end caps 70 are for closing both end openings of the upper frame cover part 42. In the present embodiment, the end cap 70 in which the mounting plate portion 71, the cover overlapping portion 72, the closing plate portion 73, and the passage forming portion 74 are integrally molded is applied. The mounting plate portion 71 is a flat plate-shaped portion extending along the substrate portion 41. The cover overlapping portion 72 is a portion configured to have a shape capable of covering the outer peripheral portion of the end portion of the upper frame cover portion 42 when the mounting plate portion 71 is arranged at a position that is an extension of the substrate portion 41. The closing plate portion 73 is a flat plate-like portion that can cover the end face opening of the upper frame cover portion 42 when the cover overlapping portion 72 is overlapped with the outer peripheral portion of the end portion of the upper frame cover portion 42. The passage forming portion 74 is a hollow box-like portion that projects along the mounting plate portion 71 from a portion of the closing plate portion 73 that is close to the mounting plate portion 71, and is formed in the lower surface and the end surface opening of the upper frame cover portion 42. It is open only in the corresponding part. As is clear from the figure, the opening 74 a provided on the lower surface of the passage forming portion 74 is located below the prospective surface 11 a on the outer peripheral side of the upper frame 11, that is, the upper surface 11 a of the upper frame 11. The dimension 70w of the passage forming portion 74 along the prospective direction is set to a value smaller than the width Dw of the ventilation layer D.

  When the above-mentioned end cap 70 is attached to the end of the upper draining member 40, the closing plate portion 73 abuts against the prospective surface 13a on the outer peripheral side of the vertical frame 13, and the inside of the passage forming portion 74. The finding surface 74b facing to the water contacting the water blocking material 30, and also contacting the surface of the waterproof sheet material 20 that covers the portion of the outer surface Bd of the skeleton B that is the side edge of the opening H.

  The outer wall material C described above is provided so as to cover the exterior sheet material Bc at a stage after the upper draining member 40 and the end cap 70 are attached. The gap between the inner surface of the window hole Ca provided in the outer wall member C and the upper draining member 40 and the gap between the inner surface of the window hole Ca and the end cap 70 are sealed by filling a sealing material 80. To be done. At this time, a communication port 81 for communicating the ventilation layer D formed between the skeleton B and the outer wall material C to the outside is secured at an appropriate position between the upper draining member 40 and the outer wall material C. I have to. The communication port 81 may be filled with the sealing material 80 in a state where components for forming the communication port 81 are arranged in advance, or may be configured by filling the sealing material 80 discontinuously. . The gap between the outer peripheral side of the vertical frame 13 and the prospective surface 13a is filled with the sealing material 80 so that the entire length is sealed. Between the outer wall material C and the lower frame 12, the lower draining member 90 is mounted on the prospective surface on the outer peripheral side of the lower frame 12, and between the lower surface of the lower draining member 90 and the inner surface of the window hole Ca. The entire length of the gap is sealed by filling the sealing material 80. Since the passage forming portion 74 provided in the end cap 70 has a smaller dimension along the prospective direction than the ventilation layer D, it is arranged inside the ventilation layer D without coming into contact with the outer wall material C.

  In the waterproof structure configured as described above, since the upper draining member 40 is provided on the outer surface Bd of the skeleton B in a portion extending from the upper edge of the opening H to the outside of the outer wall material C, ventilation is performed. There is no possibility that water such as rainwater passing through the layer D will enter the room side through the space between the frame B and the upper frame 11. The water that has reached the upper surface of the upper draining member 40 in the ventilation layer D is discharged to the outside through the communication port 81, or is discharged downward from both ends of the upper draining member 40. Further, the waterproof sheet material 20 is provided on the inner surface Ha of the opening H, and the water blocking material 30 is provided on the entire length between the waterproof sheet material 20 and the prospective surface 13a on the outer peripheral side of the vertical frame 13. Therefore, there is no possibility that water passing through the ventilation layer D will pass through the water blocking material 30 and reach the indoor side. As a result, even with respect to the frame body 10 that does not have protruding portions such as nailing fins along the finding direction on the prospective surfaces 11a, 12a, 13a on the outer peripheral side, sufficient waterproofness is provided between the frame body B and the frame body 10. Can be secured. This makes it possible to install the frame body 10 at an arbitrary prospective position with respect to the opening H of the skeleton B without impairing the waterproof property.

  Moreover, since the water blocking material 30 is made to extend between the upper surface 11a of the upper frame 11 and the waterproof sheet material 20 facing the upper surface 11a, the upper surface of the upper frame 11 and the upper draining member 40 are tentatively arranged. Even if water invades into the space between them, the water blocking material 30 suppresses the invasion into the room.

  Further, in this waterproof structure, a portion of the gap between the frame 10 and the inner surface Ha of the opening H, which is on the indoor side of the water blocking member 30, is in communication with the ventilation layer D by the passage forming portion 74. Become. That is, in the passage forming portion 74, the lower end opens to the ventilation layer D below the upper surface 11a of the upper frame 11, while the upper end opens to the space between the upper surface 11a of the upper frame 11 and the upper draining member 40. Is. The waterproof material 30 provided between the upper surface 11a of the upper frame 11 and the waterproof sheet material 20 facing the upper surface 11a secures a gap between the extending ends of the waterproof material 30. For this reason, a portion on the indoor side of the water blocking material 30 and the ventilation layer D are communicated with each other through the gap between the water blocking materials 30, and a pressure difference is not generated between them. This prevents water from entering the indoor side due to the pressure difference even when the weather becomes strong outdoors.

  In the above-described embodiment, the frame 10 is made of an extruded frame formed of resin, but the frame is not necessarily formed of resin, and the frame is formed of metal such as aluminum alloy. The same can be applied to between the body and the body. Although the upper frame 11, the lower frame 12, and the left and right vertical frames 13 have the same cross-sectional shape, the upper frame, the lower frame, and the vertical frame do not necessarily have to have the same cross-sectional shape. Absent. Furthermore, although the exterior sheet material Bc is provided on the outer surface Bd of the skeleton B facing the outside of the room, the invention is not necessarily limited to this.

  Further, in the above-described embodiment, the passage forming portion 74 is provided in the upper draining member 40, and the gap is provided in the water blocking material 30 between the upper frame 11 and the skeleton B, but the present invention is not necessarily required. It is not limited to this. In the above-described embodiment, when the passage forming portion 74 is provided, the passage forming portion 74 is provided at both ends of the upper draining member 40, but it is sufficient if it is provided at least on one side. Further, the passage forming portion 74 is configured to abut on the waterproof sheet material 20 in a portion which is a side edge of the opening H on the outer surface Bd of the skeleton B, and the water blocking material 30 abuts on a portion facing the room. Therefore, there is no risk of causing a pinhole from the outdoor side to the indoor side, which is advantageous in terms of waterproofness. However, the present invention is not necessarily limited to this.
