Peel off the release paper on the side opposite 6. As shown in FIG. 7(a), the tight materials 3a and 3b are such that, before installation, the outdoor end of the outer connecting wall 27 and the outer end of the extending portion 26 are connected by the holding piece 31. As a result, the extending portion 26 is obliquely inclined toward the outdoor side. In this state, by engaging the engaging portions 9 of the tight members 3a, 3b with the tight member holders 5 of the vertical frame 14 and the lower frame 13 and attaching the tight members 3a, 3b, the extending portion 26 is vertically Since it does not come into close contact with the adhesive 15 and the horizontal adhesive 20, it is easy to attach the tight members 3a and 3b. Thereafter, as shown in FIG. 7(b), the holding piece 31 is cut out using a cutter or the like. Thereafter, as shown in FIG. 7(c), the extending portions 26 of the tight members 3a and 3b are pressed against the vertical adhesive 15 and the horizontal adhesive 20 to be bonded.

As shown in FIG. 2, the upper frame 12 is also provided with a door stop portion 4c protruding inward from the door 2 toward the indoor side, and the door stop portion 4c has a tight material holder 5 protruding toward the outdoor side. A tight material 3c is provided and held in a tight material holder 5 to which a tight material 3c is attached. The tight material 3c includes a base portion 7 that covers the outdoor side of the tight material holder 5, an engaging portion 9 that is integrally molded with the base portion 7 and engages with the tight material holder 5, and extends from the base portion 7 to the outer peripheral side. The extension part 26, the door abutting part 8 formed on the door 2 side of the base part 7 and abutting against the indoor side surface of the door 2, the outer peripheral side connecting wall 27 connecting the door abutting part 8 and the base part 7, and the inner part. A circumferential connecting wall 28 is provided. The door abutting part 8, the outer connecting wall 27, and the inner connecting wall 28 are made of a soft material, such as EPDM sponge, and the base part 7, the engaging part 9, and the extending part 26 are made of a soft material such as EPDM sponge. It is also made of a hard material, such as EPDM rubber. In the illustrated example, the contact portion 10 is not provided between the extension portion 26 and the outdoor side surface of the doorstop portion 4c, but similarly to the vertical frame 14 and the lower frame 13, the contact portion 10 is may be provided.

As shown in FIGS. 1 and 2, the door 2 has a resin frame 32 around all sides, a heat insulating material 33 such as a foamed polystyrene board is placed inside the frame, and a steel plate 34 is placed on the outside and outside of the frame 32. It is pasted and configured. As shown in FIG. 3, the door 2 has a handle 35 attached to the outdoor side and the indoor side of the door, and a lock 36 is attached above the handle 35.

As shown in FIG. 3, the hinges 11a, 11b, and 11c are provided at three locations: an upper position of the door 2, a position near the upper middle part of the door 2 in the vertical direction, and a lower position of the door 2. As described later, this fitting is designed so that when water pressure is applied to the door 2, the lower part of the door 2 is displaced toward the indoor side and is crimped to the tight members 3a and 3b of the lower frame 13 and the vertical frame 14. A dimension L1 from the lower end of the door 2 to (the center of) the lower hinge 11c is longer than a dimension L2 from the upper end of the door 2 to (the center of) the upper hinge 11a. Specifically, the dimension L1 from the lower end of the door 2 to the lower hinge 11c is 500 mm, and the dimension L2 from the upper end of the door 2 to the upper hinge 11a is 245 mm.

As explained below, this fitting is equipped with a water-resistant mechanism that uses external water pressure to improve door tightness when the water level outside the building rises due to a flood or the like.
8 and 9 show a state in which the outdoor side is submerged in water 38 to about half its height. At this time, the door 2 has a dimension L1 from the lower end of the door 2 to the lower hinge 11c that is longer than a dimension L2 from the upper end of the door 2 to the upper hinge 11a, as shown in FIG. 8(b). Then, the lower part of the door 2 is bent and deformed toward the indoor side due to the external water pressure, and as a result, the door 2 is strongly pressed against the tight material 3b of the lower frame 13 and the tight material 3a of the vertical frame 14. At this time, the tight member 3b of the lower frame is deformed so that the door abutting part 8 follows the corner part 37 of the door 2 and grips the corner part 37 of the door 2, as shown in FIG. 8(c). In addition, as shown in FIGS. 9(a) and 9(b), the tight material 3a of the vertical frame 14 is such that the door contact portion 8 is deformed along the corner portion 37 of the door 2, and the deformed door contact portion 8 is The corner portion 37 of the door 2 is gripped between the outer peripheral side connecting wall 27 and the inner peripheral side connecting wall 28. The lower the door 2 goes, the greater the amount of displacement toward the indoor side due to water pressure, and the door 2 is more strongly pressed against the tight member 3a. Since the outer connecting wall 27 and the inner connecting wall 28 are made of a harder material than the door contact portion 8, the outer connecting wall 27 and the inner connecting wall 28 do not deform even when subjected to water pressure. It is possible to maintain the original form and prevent the door abutting part 8 from being swept away by water pressure to the inner peripheral side and creating a gap between it and the door 2.

Figures 10 and 11 show, as a comparative example, a case where the dimension L1 from the bottom end of the door 2 to the lower hinge 11c and the dimension L2 from the top end of the door 2 to the upper hinge 11a are the same (both are 245 mm). It shows the case. In the comparative example, even when the door 2 is immersed in water 38 up to about half, the lower end of the door 2 is only slightly displaced toward the indoor side, and the EE cross section rises 245 mm above the lower end of the door 2 (Fig. 8), the door 2 does not move toward the indoor side because it is restrained by the hinge 11c, as shown in FIG. 11(a), so the tightness of the tight material 3a This may become insufficient and water may enter from between the tight material 3a and the door 2.

In this way, when water pressure is applied to the door 2, the lower part of the door 2 is displaced toward the indoor side and press-fitted to the tight members 3a, 3b of the lower frame 13 and the vertical frame 14, and the tight members 3a, 3b Since it grips the corner portion 37 of the door 2, it is possible to prevent water from entering the room from between the door 2 and the tight members 3a and 3b.
