The action of the water stop plate 10 of this embodiment will be described with reference to FIGS. 6 to 8. FIG.
A water stop plate 10 is arranged in a gap G formed between the opening 2 and the foundation 4 . When a flood occurs, water may enter the internal space I from the external space O through the gap G. By being arranged in the gap G, the first base material 21 suppresses entry of water through the gap G. As shown in FIG. A water expansion member 30 is provided on the second main surface 21B of the first base material 21 . The water expansion member 30 on the second main surface 21B absorbs water that has entered the gap G and expands. A water expansion member 30 is provided on the second main surface 22B of the second base material 22 . Therefore, the gap G between the side frame 2B of the opening 2 and the first base material 21 becomes smaller in the portion of the first base material 21 of the water stop plate 10 that overlaps the opening 2 . The water expansion member 30 on the second main surface 22B absorbs water that has entered the gap G and expands. Therefore, the gap G between the side surface 4D of the foundation 4 and the second base material 22 becomes smaller in the portion of the second base material 22 of the water stop plate 10 that overlaps the foundation 4 . As a result, entry of water from the outer space O into the inner space I is suppressed. As shown in FIGS. 7 and 8, the apex of the second base material 22 in the longitudinal direction XA coincides with the height of the top surface 4A of the foundation 4. As shown in FIGS. For this reason, the ingress of water up to the top surface 4A of the foundation 4 is suppressed.

According to the water stop plate 10 of this embodiment, the following effects are obtained.
(1) The water stop plate 10 is provided in the gap G between the opening 2 of the building 1 and the foundation 4 . The water stop plate 10 prevents water from entering through the gap G. The water stop plate 10 includes a base material 20 and a water expansion member 30 that expands by absorbing water.

The water stop plate 10 of this embodiment includes a water expansion member 30 . Since the water expansion member 30 expands when water enters, at least a part of the periphery of the water stop plate 10 can be made watertight. This can prevent water from entering the internal space I of the building 1 from the external space O of the building 1 .

(2) The base material 20 includes a first base material 21 facing the frame of the opening 2 and a second base material 22 facing the side surface 4D of the foundation 4 . At least one of the first substrate 21 and the second substrate 22 has a water-swellable member 30 .

According to the configuration of the water stop plate 10 of this embodiment, the gap G is less likely to be formed between the water stop plate 10 and the opening 2 or between the water stop plate 10 and the foundation 4 . For this reason, the intrusion of water into the internal space I of the building 1 is further suppressed.

(3) The water-swellable member 30 is composed of at least one of water-swellable urethane foam and water-swellable nonwoven fabric.
According to the configuration of the water stop plate 10 of this embodiment, the water expansion member 30 is made of an appropriate material, so that water is further suppressed from entering the internal space I of the building 1 .

(4) The base material 20 is fixed to the foundation 4 with the fixing member 40 .
According to the configuration of the water stop plate 10 of this embodiment, the water stop plate 10 is preferably attached to the foundation 4 .

(5) The water expansion member 30 includes a first water expansion member 31 and a second water expansion member 32 . Each of the water expansion members 30 is composed of different materials.
According to the structure of the water stop plate 10 of this embodiment, the first water expansion member 31 and the second water expansion member 32 are made of different materials. The first water expansion member 31 and the second water expansion member 32 may be made of materials with different expansion coefficients. In this case, the material of the water expansion member 30 may be changed between the portion into which water is likely to enter from the external space O and the portion into which water is difficult to enter. With this configuration, it is possible to suitably suppress the intrusion of water. Suitable water suppression can suppress water intrusion for an extended period of time.

(6) The building 1 is equipped with a water cutoff plate 10 .
According to the structure of the building 1 of this embodiment, water is suppressed from entering the internal space I of the building 1 from the external space O of the building 1 .

(7) At least part of the base material 20 is covered with the finishing member 50 in the building 1 .
According to the structure of the building 1 of this embodiment, the designability of the portion where the water stop plate 10 is provided is improved.
