Utility Model Application Publication No. 59-142383

According to the waterproof entrance disclosed in Patent Document 1, although the waterproof performance between the opening/closing body and the wall (opening frame) is enhanced, the opening/closing body cannot be used in the recent frequent guerrilla rainstorms. As a result, the opening/closing body is flexed, resulting in an insufficient sealing state between the opening/closing body and the wall, causing water to enter from the entrance.

Therefore, the present invention provides a waterproof door that can suppress deformation of the opening/closing body due to water pressure and maintain a sealed state between the opening/closing body and the wall (opening frame) even if the water pressure acting on the opening/closing body of the entrance increases. The purpose is to provide a gateway.

The reinforcing frame is attached so as to protrude from the outside side surface of the building of the opening, and the inside side surface of the opening and closing body of the building contacts the outside side surface of the standing portion with the waterproof packing. The position of the inner side surface of the building when the opening and closing body abuts through the opening is flush with the heat insulating material attached to the building, and the opening edge of the opening of the building is made of heat insulating material A water-resistant entrance characterized by a reinforcing frame fixing spacer formed by

This suppresses the bending of the opening/closing body due to water pressure, maintains the sealed state between the opening/closing body and the reinforcing frame, and prevents water from entering the building through the entrance even during a flood. In addition, the opening/closing body can be arranged cleanly and firmly in a reinforced concrete externally insulated building.

It is preferable that the water stop packing is attached to a pressure resistant rubber fixed to the upright portion.

Thereby, waterproofness can be improved further.

Moreover, it is preferable that the pressure-resistant rubber is fixed to the tip portion of the standing portion.

As a result, the support span length of the opening/closing body by the pressure-resistant rubber (water stop packing) can be shortened, so that the deflection amount of the opening/closing body due to water pressure can be further reduced, and the water resistance can be further improved.

In addition, on the inner side surface of the building of the opening/closing body, opening/closing body pressing tools for pressing the opening/closing body against the upright portion are arranged at a plurality of positions along the longitudinal edge on the non-mounted side of the opening/closing hinge. It is preferable that

As a result, the opening/closing body can be firmly pressed against the building, so that it is possible to more reliably prevent water from entering the building.

Moreover, it is preferable to further include a hat-shaped cover which can be attached to the exterior side surface of the building of the opening/closing body and which can accommodate the keyhole and the handle portion of the opening/closing body.

As a result, it is possible to prevent water from entering the building through the keyhole portion and the handle portion of the opening/closing body.

According to the structure of the water resistant entrance of the present invention, even if a general opening/closing body is used, it is possible to suppress the bending of the opening/closing body due to water pressure, and maintain the sealed state between the opening/closing body and the reinforcing frame. becomes possible. Therefore, it is possible to prevent water from entering the building in the event of a flood or the like, even if the entrance is equipped with a general opening/closing member.

A reinforcing frame 30 and an opening/closing member 40 for opening/closing the opening 14 are provided. In the present embodiment, a so-called externally insulated reinforced concrete house 10 in which a general front door is employed as the opening/closing body 40 will be described. The opening/closing body 40 is attached so as to be able to be opened/closed by means of an opening/closing hinge HJ provided on the inner peripheral surface of the opening frame 20, so that the opening frame 20 (opening portion 14) can be switched between an open state and a closed state. . Known configurations can be adopted for the individual configurations of the house 10, the wall surface 12, the opening 14, the opening frame 20, and the opening/closing member 40 in this embodiment.

The opening frame 20 in this embodiment is installed in a state in which watertightness with the opening 14 is ensured by interposing a water stop member (not shown) between the opening 14 formed in the wall surface 12 of the house 10. It is Further, the inner peripheral surface of the opening frame 20 in this embodiment is parallel to the inner peripheral surface of the opening 14 and is attached so as to cover the entire range of the inner peripheral surface of the opening 14 . A heat insulating material 16 having a required thickness is attached to the outer side surface (outer surface) of the wall surface 12 .

As is clear from FIGS. 2 and 3, the reinforcing frame 30 has a base portion 32 that contacts the inner peripheral surface of the opening frame 20 and an upright portion 34 that rises from the base portion 32. A steel material having an L-shaped cross section is welded or bonded. is formed into a rectangular frame by the known technique of The outer dimensions of the reinforcing frame 30 are formed to have substantially the same dimensions as the inner peripheral surface dimensions of the opening frame 20, and through holes KH are drilled at a plurality of locations in the base portion 32 at required intervals. The reinforcing frame 30 is in a state in which the standing portion 34 is erected with respect to the inner peripheral surface of the opening frame 20 within the range of the inner peripheral surface of the opening frame 20, and the base portion 32 is extended toward the inside of the house 10. is attached to the inner peripheral surface of the opening frame 20 with a screw N at the position of the through hole KH.

In this embodiment, the standing portion 34 is attached to the opening frame 20 so as to protrude outward from the outer end position of the opening frame 20, and the pressure resistant rubber 50 and the water stop packing 60 attached to the standing portion 34 The position of the inner side surface of the opening/closing body 40 and the position of the outer side surface of the heat insulating material 16 are flush with each other. By doing so, it is possible to improve the fit of the opening/closing body 40 with respect to the house 10 having an external heat insulation structure.

In addition, on the outer side surface of the wall surface 12, a reinforcing frame fixing member formed of a heat insulating material and having the same thickness as the heat insulating material 16 is provided in a required width range along the opening edge of the opening frame 20. A spacer 18 is attached. Resin wood can be preferably used for such a reinforcing frame fixing spacer 18 . By arranging the reinforcing frame fixing spacer 18 made of a heat insulating material along the opening edge of the opening frame 20 (opening 14) in this way, the heat insulating performance in the portion where the heat insulating material 16 is not arranged is improved. can be ensured. Further, the reinforcing frame 30 has a part of the base portion 32 fixed to the reinforcing frame fixing spacer 18 and the inner peripheral surface of the opening frame 20 from a plurality of directions by a known method such as screws N, and acts on the reinforcing frame 30. An external force can be reliably transmitted to the wall surface 12 of the house 10.例文帳に追加Furthermore, a waterproof member (not shown) can be arranged between the base 32 and the opening frame 20 .

A pressure-resistant rubber 50 is fixed to the outer side surface of the tip portion of the upright portion 34 in this embodiment by a known method such as adhesion. Also, a waterproof packing 60 is attached to the outer side surface of the pressure resistant rubber 50 by a known technique such as adhesion. Furthermore, tape caulking 70 is applied between the outer side surface of the standing portion 34 and the inner peripheral surface of the opening frame 20 .

As a result, the supporting position of the opening/closing body 40 when water pressure is applied during a flood or the like is shifted from the outer peripheral edge position of the opening/closing body 40 to the inside position of the opening/closing body 40 by the standing dimension of the standing portion 34. It becomes possible to support the hard urethane-filled portion 41 of the entrance door (the portion having sufficient mechanical strength). In addition, the support span of the opening/closing body 40 can be shortened, which contributes to the reduction of the amount of deflection when water pressure is applied. Furthermore, the external force acting on the opening/closing body 40 can be transmitted to the standing portion 34 and also transmitted to the entire inner peripheral surface of the opening frame 20 via the base portion 32 integrally formed with the standing portion 34 .

Since the reinforcing frame 30 having the standing portion 34 that stands up against the inner peripheral surface of the opening frame 20 is provided along the inner peripheral surface of the opening frame 20 in this manner, the opening/closing body 40 can be secured even when a flood occurs. Even if the water pressure acts on the opening and closing body 40, the amount of bending that occurs in the opening and closing body 40 can be reduced as much as possible. That is, the sealed state between the water stop packing 60 arranged on the standing portion 34 and the opening/closing body 40 can be reliably maintained. Therefore, even if a normal entrance door is used as the opening/closing member 40, it is possible to reliably prevent water from entering the house 10 through the entrance portion (opening 14).

Further, as shown in FIG. 1, the opening/closing body 40 in this embodiment is provided with a through hole (not shown) outside the keyhole 42 and the handle portion 44, and the through hole is covered. A washer plate 98 having a through hole (not shown) that is sized and aligned with the through hole is attached to the interior side surface by a fastening member 99 . The washer plate 98 and the fastening member 99 are used to previously cover the keyhole 42 and the handle portion 44 with the outer surface of the opening/closing body 40 when flooding is expected. Here, bolts and nuts are used as the fastening members 99 .

Furthermore, in the opening/closing body 40 in this embodiment, the opening/closing body pressers 80 are arranged at a plurality of positions at equal intervals along the longitudinal edge of the opening/closing hinge non-attached side to which the opening/closing hinge HJ is not attached. is set. The opening/closing body pressing tool 80 can be operated from the inside of the house 10, and is for further pressing the opening/closing body 40 already in contact with the waterproof packing 60 of the standing portion 34.

As shown in FIG. 4, the lever 88 and the pressing projection 89 are in a state along the height direction of the opening/closing body 40 (parallel to the inner side surface of the opening/closing body 40) when not pressed (normal time). The projection 89 is in a state where it is not in contact with anything.

As shown in FIG. 5, when pressed (at the time of flooding), the lever 88 is rotated forward from the inside of the house 10 . As a result, the pressing projection 89 formed at the tip of the operating rod 86 stands up against the inner side surface of the opening/closing body 40 . At this time, the distance from the rotation axis of the operating rod 86 to the tip position of the pressing projection 89 is longer than the distance from the rotation axis of the operating rod 86 to the upright portion 34 . As a result, the pressing projection 89 is erected on the inner side surface of the standing portion 34, so that the opening/closing body 40 is drawn from the outside to the inside, and the pressing state between the opening/closing body 40, the waterproof packing 60, and the pressure resistant rubber 50 is strengthened. As a result, the water cut-off property of the opening/closing body 40 can be further enhanced.
