  However, when the sealing material shown in FIG. 7A breaks due to aging or the like, as shown in FIGS. 7B and 7C, as the broken portion, the contact portion between the outer wall panel and the sealing material Rainwater, etc. infiltrate from the gaps formed in And the rainwater etc. which permeated will further permeate into the gap on the base material side of the sealing material. Here, since the sealing material shown in FIG. 7 (a) has no drainable structure, rainwater or the like that has entered the gap on the base material side of the sealing material is shown in FIG. 7 (d). In addition, there is a possibility that water leaks without being completely stopped by the EPDM sponge. On the other hand, although both the draining structure disclosed in Patent Document 1 and the joint structure disclosed in Patent Document 2 are drainable structures, there are the following problems.

  That is, the support member which comprises the draining structure of patent document 1 becomes a structure attached to a horizontal joint by being fixed with a bis | screw with respect to the attachment member fixed to the building frame. Therefore, there has been a problem that the support member cannot be inserted and attached to the horizontal joint from the outdoor side toward the indoor side. Moreover, the secondary waterproofing member which comprises the joint structure of patent document 2 has a fitting part fitted between a lower outer wall surface material and a lower panel frame. Therefore, when the upper outer wall surface material and the lower outer wall surface material are assembled in advance, the fitting portion becomes an obstacle when the secondary water stop member is inserted into the horizontal joint from the outdoor side toward the indoor side. There was a problem that it was difficult to attach the secondary water stop member.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to make it easy to mount a water-stopping member, particularly a water-stopping member, on a water-stopping structure to be attached to the cross-joint. It is to realize the installation.

  In order to solve the above-described problem, a water stop member according to an aspect of the present invention is a horizontal joint between a first outer wall panel and a second outer wall panel disposed vertically below the first outer wall panel. A water-stopping member attached to the vertical outer surface of the second outer wall panel, wherein the base-stopping member is attached to the horizontal joint. In the state, a rising portion formed of an elastic body is provided that rises upward in the vertical direction so as to face an end portion on the indoor lower side wall surface of the first outer wall panel.

  According to the above configuration, when the water stop member according to the present invention is inserted into the horizontal joint from the indoor side toward the outdoor side, the start-up portion formed of the elastic body flexes flexibly, so that the insertion is easy. become. In addition, the rising portion automatically rises upward when the rising portion comes out of the opening on the indoor side of the horizontal joint, as before the insertion, and on the indoor side wall surface of the first outer wall panel. It arrange | positions so that the edge part of a perpendicular lower side may be opposed. Therefore, it is not necessary to separately perform the work for raising the rising portion as described above after the water-stopping member is inserted into the horizontal joint. Therefore, it is possible to realize a water stop member that can be easily attached to the horizontal joint.

  In order to solve the above-described problem, in the water-stopping member according to one aspect of the present invention, the rising portion is partially formed thin, and the thin-walled portion is formed in the water-stopping member. When the water member is inserted into the horizontal joint from the outdoor side toward the indoor side, the water member is more easily bent than the other portions of the rising portion, and the desired bending property of the rising portion when inserting the water member. It is preferable to function as a bent portion for ensuring the above.

  According to the above configuration, since the thin bent portion is formed in a part of the rising portion, when the water stop member according to the present invention is inserted into the horizontal joint from the outdoor side toward the indoor side, the rising portion is The part bends as a whole and bends starting from the bent part. Therefore, since the water-stopping member according to the present invention can be more easily inserted into the horizontal joint, a water-stopping member that can be more easily attached to the horizontal joint can be realized.

  Moreover, in order to solve said subject, in the water stop member which concerns on 1 aspect of this invention, the said bending part is the said in the said 1st outer wall panel in the state in which the said water stop member was attached to the said horizontal joint. It is preferable that it is formed vertically lower than the surface facing the second outer wall panel.

  According to the above configuration, when the water stop member according to the present invention is inserted into the horizontal joint from the indoor side toward the outdoor side, the rising portion is more than the case where the bent portion is formed vertically above the opposing surface. As a result of the bending, the number of rising portions that fall toward the base portion increases. Therefore, since the rising portion can be further tilted toward the base portion, the water-stopping member according to the present invention can be more easily inserted into the horizontal joint, and more easily attached to the horizontal joint. .

  Moreover, in order to solve said subject, in the water stop member which concerns on 1 aspect of this invention, the front-end | tip part of the said raising part becomes thicker than parts other than the said front-end | tip part in the said raising part. Preferably it is.

  According to the above configuration, the area of the tip surface at the tip is larger than when the thickness of the tip is the same as the thickness of the portion other than the tip. Therefore, since it becomes easy for the user to press the front end surface of the front end portion, when the water stop member according to the present invention is inserted from the indoor side to the outdoor side in the horizontal joint, the front end portion of the start-up portion is placed on the outdoor side. By bending the rising portion so as to face, the tip surface of the tip portion can be pressed, and the rising portion can be easily pushed into the indoor side of the horizontal joint. At the time of the push-in, the base portion 11 is also pushed into the indoor side of the horizontal joint following the rising portion, so that the water-stopping member according to the present invention can be more easily inserted into the horizontal joint, and thus the horizontal joint. It becomes easier to install.

  Moreover, in order to solve said subject, in the water stop member which concerns on 1 aspect of this invention, the front-end | tip part of the said raising part is the said 1st in the state in which the said water stop member was attached to the said horizontal joint. It is preferable to contact the indoor side wall surface of the outer wall panel.

  According to the above configuration, since the indoor side wall surface of the first outer wall panel is sealed by the tip of the rising portion, for example, the first outer wall panel / second outer wall panel and the base disposed on the indoor side from these It is possible to effectively prevent rainwater or the like that has entered the gap with the material from entering the interior of the horizontal joint from the indoor opening of the horizontal joint.

  Moreover, in order to solve said subject, the horizontal joint water stop structure which concerns on 1 aspect of this invention is the 1st outer wall panel and the 2nd outer wall panel distribute | arranged to the perpendicular | vertical lower side of the said 1st outer wall panel. A water stop member attached to the horizontal joint, and a parting member attached to the horizontal joint so as to face the water stop member, and covering the horizontal joint from the outdoor side in a state of being attached to the horizontal joint. A horizontal joint water stop structure provided, wherein the water stop member has a base portion mounted on a vertical upper surface of the second outer wall panel and the water stop member attached to the horizontal joint. In the state, a rising portion formed of an elastic body is provided that rises vertically upward so as to face the vertical lower end of the indoor side wall surface of the first outer wall panel. Place the parting member above the vertical upper surface. A protrusion for fixing to the horizontal joint protrudes vertically upward, and the parting member has a fixing lip part formed of an elastic body extending from the vertically lower surface of the parting member. The tip of the fixed lip portion is hooked on the protrusion in a state where the parting member is attached to the horizontal joint.

  According to the said structure, when inserting a water stop member into a horizontal joint from the indoor side toward the outdoor side, since the starting part formed with the elastic body bends flexibly, the said insertion becomes easy. Further, when the parting member is inserted into the horizontal joint from the indoor side toward the outdoor side, the fixed lip portion formed of an elastic body flexes flexibly, so that the insertion becomes easy. Therefore, it is possible to realize a horizontal joint waterproof structure that can be easily attached to the horizontal joint.

<Structure of the horizontal joint structure>
First, with reference to FIG. 1, the structure of the horizontal joint waterproof structure 30 which concerns on one Embodiment of this invention is demonstrated. FIG. 1 is a cross-sectional view illustrating a schematic configuration of a horizontal joint waterproof structure 30. In the following description, for the sake of convenience, the upper vertical side is the upper side, the lower vertical side is the lower side, the right side toward the page is the right side, and the left side is the left side toward the page. The right side is the indoor side and the left side is the outdoor side.

  The horizontal joint waterstop structure 30 is attached to the horizontal joint M between the upper outer wall panel (first outer wall panel) 1 and the lower outer wall panel (second outer wall panel) 2 fixed to the base material 3, Prevents intrusion of rainwater, etc. into the horizontal joint M. Further, the horizontal joint water-stopping structure 30 discharges rainwater and the like that has entered the horizontal joint M to the outside. As shown in FIG. 1, the horizontal joint water stop structure 30 includes a water stop member 10 and a parting member 20. The base material 3 is composed of a pillar, a beam, a frame, a wall, or the like.

(Water stop member)
The water stop member 10 drains rainwater or the like that has entered the inside of the horizontal joint M to the outside, and in combination with a fixed lip portion 23 (details will be described later) provided on the parting member 20, the parting member 20 is connected to the horizontal joint M. It plays a role to fix. As shown in FIG. 1, the water stop member 10 includes a base portion 11 and a rising portion 12. The base portion 11 is made of, for example, metal or hard resin. The rising portion 12 is made of, for example, natural rubber, a rubber material mainly composed of IR (isoprene rubber) or CR (chloroprene rubber), or various thermoplastic elastomers, urethane, PVC (polyvinyl chloride), and other soft resins. It is formed of a like elastic body. In the present specification, rubber materials or rubber-like elastic bodies are collectively referred to as “elastic bodies”.

  The base portion 11 is placed on the upper surface (vertical upper surface) 2 a of the lower outer wall panel 2. The portion arranged in the horizontal joint M on the upper surface of the base portion 11 is continuously downward from the indoor side to the outdoor side in order to drain rainwater or the like that has entered the horizontal joint M to the outdoor side. Inclined. Further, the lower surface of the base portion 11 is fixed to the horizontal joint M so that the user can easily insert the water blocking member 10 into the horizontal joint M from the outdoor side toward the indoor side. Because of this, it has become the same.

  In addition, it is not essential to provide the above-described inclination on the upper surface of the base portion 11. However, in consideration of drainage to the outdoors such as rainwater, it is preferable that the above-mentioned inclination is provided. Further, the lower surface of the base portion 11 does not have to be flush. In other words, the lower surface of the base portion 11 can be easily inserted from the outdoor side to the indoor side by the user toward the horizontal joint M, and the water stop member 10 is mounted on the upper surface 2 a of the lower outer wall panel 2. Any shape that allows the water-stopping member 10 to be stably fixed to the horizontal joint M in the placed state is acceptable.

  Further, from the outdoor side end portion of the base portion 11, a protruding portion 11 a that hooks on the tip 23 a of the fixed lip portion 23 provided on the parting member 20 protrudes upward. Further, the protruding portion 11a is formed in a wall shape along the longitudinal direction of the base portion 11 (the direction perpendicular to the paper surface). A tip 23a of the fixed lip 23 is hooked on the projection 11a, and an attachment base 22 (specifically, two contact lip portions 22a and a water stop sponge 22b; details of the attachment base 22 will be described later) is provided on the upper outer wall. The parting member 20 is fixed to the horizontal joint M by contacting the lower surface 1 a of the panel 1.

  In addition, it is not essential that the protrusion part 11a is provided in the outdoor side edge part of the base part 11, and it is a base part so that the decorative part 21 (it mentions later for details) of the parting member 20 is not arrange | positioned inside the horizontal joint M. 11 should just protrude from the upper surface of 11. Further, a notch-shaped projection-side drainage channel (not shown) corresponding to the formation position / number of drainage channels 23b formed in the fixed lip 23 of the parting member 20 may be formed on the projection 11a. Good. By forming such a protrusion-side drainage channel, it is possible to easily drain rainwater or the like flowing out from the drainage channel 23b of the fixed lip 23 to the outdoors.

  Further, the end surface of the indoor side end portion of the base portion 11 abuts on the outdoor side wall surface 3 a of the base material 3 in a state where the water blocking member 10 is attached to the horizontal joint M. In this way, the end surface of the indoor side end portion of the base portion 11 abuts on the outdoor side wall surface 3a of the base material 3, so that the user inserts the water stop member 10 into the horizontal joint M from the outdoor side toward the indoor side. In doing so, the water stop member 10 can be easily positioned, and the water stop member 10 can be more securely fixed to the horizontal joint M. In the state where the water stop member 10 is attached to the horizontal joint M, it is not essential that the end surface of the indoor side end portion of the base portion 11 abuts on the outdoor side wall surface 3 a of the base material 3. That is, in the state where the water stop member 10 is attached to the horizontal joint M, a gap may be formed between the indoor side end portion of the base portion 11 and the base material 3.

  In addition, a plurality of cutout ventilation paths 11 b are formed in the longitudinal direction of the base portion 11 at the indoor side end of the base portion 11. The ventilation path 11b drains rainwater or the like infiltrated from above the ventilation layer so as not to block ventilation in the ventilation layer formed between the upper outer wall panel 1 / lower outer wall panel 2 and the base material 3. It is a space to do. The shape and the number of the ventilation paths 11b can be arbitrarily designed as long as they do not affect the positioning and fixing of the water stop member 10 to the horizontal joint M.

  (I) the upper surface 2a of the lower outer wall panel 2, (ii) the upper surface of the base portion 11 and the end face on the outdoor side, formed in a state where the horizontal joint waterproof structure 30 is attached to the horizontal joint M, (iii) The space surrounded by the indoor side surface of the decorative portion 21 in the parting member 20, (iv) the lower surface of the mounting base portion 22 and (v) the outdoor side surface of the fixed lip portion 23 is for draining rainwater or the like outdoors. Functions as a drainage space. The drainage space also includes a drainage channel 23b.

  The rising portion 12 is a substantially flat plate-like portion rising from the upper surface of the base portion 11 toward the upper side in the vertical direction, and is formed along the longitudinal direction of the base portion 11. Further, the rising portion 12 is vertical so as to face the lower end portion (vertical lower end portion) of the indoor side wall surface 1b of the upper outer wall panel 1 in a state where the water stop member 10 is attached to the horizontal joint M. It is the length in the direction and the arrangement position on the base portion 11. The ventilation layer formed between the upper outer wall panel 1, the lower outer wall panel 2, and the base material 3 by setting the vertical length of the rising portion 12 and the arrangement position on the base portion 11 as described above. The rainwater or the like that has entered from above is prevented from entering the horizontal joint M through the indoor opening of the horizontal joint M. Alternatively, rainwater or the like that has entered from the gap between the attachment base 22 of the parting member 20 and the upper outer wall panel 1 is further prevented from entering the ventilation layer.

  Further, the tip portion 12a of the rising portion 12 is thicker than the portion of the rising portion 12 other than the tip portion 12a, and in the state where the water stop member 10 is attached to the horizontal joint M, the tip portion The end face on the outdoor side of the portion 12 a contacts the indoor side wall surface 1 b of the upper outer wall panel 1. By making the shape and size of the tip portion 12a of the rising portion 12 as described above, the indoor side wall surface 1b of the upper outer wall panel 1 is sealed by the tip portion 12a of the rising portion 12, and the horizontal joint M is formed from the ventilation layer. Intrusion of rainwater into the water can be prevented more reliably. Further, when the water stop member 10 is inserted into the horizontal joint M, the distal end portion 12a of the rising portion 12 is bent so as to face the outdoor side. However, since the distal end surface of the distal end portion 12a is widened, the insertion In this case, the user can easily push the start-up unit 12 into the indoor side.

  If only the ease of pushing the rising portion 12 when inserting the water stop member 10 into the horizontal joint M is considered, the thickness of the tip portion 12a of the rising portion 12 is set to the thickness of the upper outer wall panel 1. It is not necessary to make it thick enough to abut against the indoor side wall surface 1b. In addition, in the rising portion 12, even if the tip portion 12a and the other portions have the same thickness, it is possible to prevent rainwater and the like from entering the horizontal joint M to some extent, so that the tip portion 12a is thicker than the other portions. It is not essential to make meat.

  Furthermore, the site near the root and the vertical middle region in the rising portion 12 are formed thinner than other sites. Specifically, in the part near the base and the intermediate part in the vertical direction, depressions having substantially the same size and depth are formed on the indoor side and the outdoor side, respectively. Further, the intermediate portion in the vertical direction is formed vertically below the lower surface 1 a of the upper outer wall panel 1 in a state where the water blocking member 10 is attached to the horizontal joint M.

  These thinly formed portions are more easily bent than the other portions of the rising portion 12 when the water-stopping member 10 is inserted into the horizontal joint M from the outdoor side toward the indoor side. It functions as a bent portion 12b for ensuring the desired flexibility of the rising portion 12 at the time. By forming such a bent portion 12b in the rising portion 12, the water stop member 10 can be more easily inserted into the horizontal joint M from the outdoor side toward the indoor side.

  The number, formation position, and shape of the bent portions 12b are not limited to those described above. Since the bent part 12b is a part for facilitating the insertion of the water stop member 10 into the horizontal joint M from the outdoor side toward the indoor side, the number thereof may be one, or the rising part 12 does not have to be formed with the bent portion 12b. Also, the formation position of the bent portion 12b can be arbitrarily designed. However, in terms of the ease of bending of the entire rising portion 12 when inserted into the horizontal joint M, the bent portion 12b has a lower surface 1a of the upper outer wall panel 1 in a state where the water stop member 10 is attached to the horizontal joint M. It is preferable that it is formed vertically below. Furthermore, it is more preferable that the bent portion 12 b is formed at least near the base of the rising portion 12. Further, the shape of the bent portion 12b can be arbitrarily designed. However, at the time of inserting the water-stopping member 10 into the horizontal joint M, in order to make the entire rising portion 12 bendable on the outdoor side, at least a part of the outdoor-side surface of the rising portion 12 is depressed. preferable.

  In other words, in order to make it easier to insert the water-stopping member 10 into the horizontal joint M from the outdoor side toward the indoor side, it is only necessary that the rising portion 12 is formed thin in part.

(Parting material)
The parting member 20 is attached to the horizontal joint M so as to face the water stop member 10, thereby preventing rainwater and the like from entering from the outdoor side of the horizontal joint M. As shown in FIG. The decorative part 21 and the attachment base part 22 are formed continuously. The decorative portion 21 and the attachment base portion 22 are formed of, for example, an elastic body or a hard resin.

  The decorative part 21 is a flat plate-shaped part, and covers the opening on the outdoor side of the horizontal joint M so that the horizontal joint M cannot be seen from the outside. The surface on the outdoor side of the decorative portion 21 is covered with, for example, a hard resin.

  The mounting base portion 22 is a flat plate-like portion disposed so as to face the lower surface (a surface facing the second outer wall panel of the first outer wall panel) 1 a of the upper outer wall panel 1. A fin-shaped contact lip portion 22a that contacts the lower surface 1a of the upper outer wall panel 1 is provided on each of the end surface and the indoor side end surface. Further, a waterproof sponge 22b mainly composed of EPDM (ethylene / propylene diene monomer) as a waterproof layer is attached between the two contact lip portions 22a, and the waterproof sponge 22b is also an upper outer wall panel. 1 is in contact with the lower surface 1a. As described above, the two contact lip portions 22a and the water-stop sponge 22b contact the lower surface 1a of the upper outer wall panel 1 so that rainwater and the like enter from the gap between the mounting base portion 22 and the upper outer wall panel 1. To prevent.

  The upper surface of the mounting base 22 may be brought into direct contact with the lower surface 1a of the upper outer wall panel 1 without providing the two contact lip portions 22a and without attaching the water stop sponge 22b.

  A plurality of fixing lip portions 23 for fixing the parting member 20 to the horizontal joint M are provided at the indoor side end of the mounting base 22 along the longitudinal direction of the parting member 20 (perpendicular to the paper surface). ing. Specifically, as shown in FIG. 1, the lower surface of the indoor side end portion of the mounting base portion 22 so that the tip 23 a of the fixed lip portion 23 faces the indoor side when the parting member 20 is attached to the horizontal joint M. It is extended from (the vertically lower surface of the parting member).

  The fixed lip portion 23 is formed of the above-described elastic body (rubber material or rubber-like elastic body). In addition, in a state where the parting member 20 is attached to the horizontal joint M, the tip 23a of the fixed lip part 23 is hooked on a protrusion 11a of the water-stopping member 10 described later, whereby the parting member 20 is elastically applied to the lateral joint M. Fixed.

  Therefore, even when the position of the upper outer wall panel 1 in the vertical direction changes, the parting member 20 is elastically fixed to the horizontal joint M by the fixing lip portion 23, so that the attachment base 22 and the upper outer wall panel 1 It is possible to prevent a gap from occurring between them. In addition, since the fixed lip portion 23 is formed of the above-described elastic body, when the user inserts the parting member 20 into the horizontal joint M from the outdoor side to the indoor side, it flexes flexibly and does not get in the way. And the front-end | tip 23a of the fixed lip | rip part 23 can be easily hung on the projection part 11a.

  Further, the space between the two fixed lip portions 23 adjacent to each other functions as a drainage channel 23b for draining rainwater or the like from the indoor side to the outdoor side. The number and size of the drainage channels 23b can be arbitrarily designed as long as they do not affect the fixing of the parting member 20 by the fixing lip portion 23.

  In addition, a core member 24 is embedded in the mounting base 22 to increase the rigidity of the mounting base 22 and improve the fixing force of the parting member 20 to the horizontal joint. The core member 24 is formed by folding back two outer edges in the longitudinal direction (perpendicular to the paper surface) of a flat plate-like member, and is formed of various metals such as iron or a material such as a hard resin. ing.

  In the present embodiment, as shown in FIG. 1, the outer edge on the outdoor side of the core member 24 is folded back from below the core member 24 toward the center of the core member 24, and the outer edge on the indoor side is the core member 24. From the upper side toward the center of the core member 24. However, the folding of the outer edge in the longitudinal direction of the core member 24 is not limited to the above case. For example, the folding of the outer edge on the outdoor side and the folding of the outer edge on the indoor side may be reversed from those described above. Further, since the outer edge is folded to increase the rigidity of the mounting base 22, it is not essential that the core member 24 has the outer edge folded. Furthermore, since the parting member 20 can be fixed to the horizontal joint M even if the core member 24 is not embedded in the mounting base portion 22, the core member 24 is embedded in the mounting base portion 22. That itself is not essential.

<Assembly procedure of horizontal joint structure>
Next, with reference to FIG. 2 and FIG. 3, the assembly | attachment procedure of the horizontal joint waterproof structure 30 which concerns on one Embodiment of this invention is demonstrated. 2A to 2C are schematic views illustrating an example of an assembly procedure of the horizontal joint waterproof structure 30. FIG. FIGS. 3A to 3C are schematic views illustrating another example of the assembly procedure of the horizontal joint waterproof structure 30.

During the placement, the end surface of the indoor side end portion of the base portion 11 is brought into contact with the outdoor side wall surface 3 a of the base material 3.

  (2) Next, as shown in FIG. 2B, the upper outer wall panel 1 is installed above the lower outer wall panel 2. At the time of the installation, the end surface on the outdoor side of the tip portion 12 a in the rising portion 12 is brought into contact with the indoor side wall surface 1 b of the upper outer wall panel 1.

  (3) Next, as shown in FIG. 2C, the parting member 20 is attached to the horizontal joint M by inserting the parting member 20 into the horizontal joint M from the outdoor side toward the indoor side. Specifically, the fixed lip portion 23 is bent so that the tip 23a of the fixed lip portion 23 of the parting member 20 faces the outdoor side (the outdoor side of the base portion 11 in the fixed lip portion 23 and the water stop member 10). In order to prevent the end portions from interfering with each other), the indoor side end portion of the mounting base portion 22 in the parting member 20 is inserted into the indoor side of the horizontal joint M. At this time, the abutting lip 22a and the water stop sponge 22b of the mounting base 22 are brought into contact with the lower surface 1a of the upper outer wall panel 1.

  Next, the decorative portion 21 of the parting member 20 is disposed in the vicinity of the opening on the outdoor side of the horizontal joint M while the tip 23a of the fixed lip portion 23 is hung on the protruding portion 11a of the base portion 11 of the water blocking member 10. Thus, the assembly is completed by positioning the parting member 20 as described above. In addition, since the fixed lip part 23 is formed with the above-mentioned elastic body, the fixed lip part 23 after assembling is in a state of being bent more than before assembling.

(When retrofitting a water stop member)

From the above, the shape of the connecting portion 41 is slightly curved so as to be convex toward the decorative portion 21 before the parting member 40 is attached to the horizontal joint M.

  By making the shape of the connection part 41 as described above, as shown in FIG. 4, the drainage space 42 can be secured widely even in the state where the parting member 40 is attached to the horizontal joint M, and the drainage space 42 is concerned. Rainwater that enters the inside is smoothly drained to the outside without stagnation.

  In addition, the connection portion 41 is formed with a plurality of notch-shaped drainage channels 41a for draining rainwater or the like from the indoor side to the outdoor side along the longitudinal direction of the connection portion 41 (the direction perpendicular to the paper surface). ing. The number, size, and shape of the drainage channels 41a may correspond to the number, size, and shape of the drainage channels 23b formed between the two fixed lip portions 23 adjacent to each other. The number of channels 41a and the like may be different from the number of drain channels 23b. In other words, the number and the like of the drainage channels 41a can be arbitrarily designed as long as they do not affect the drainage of rainwater or the like.

  Although not shown, the embodiment of the water stop member according to the present invention is not limited to the water stop member 10 described above, for example, the shape of the rising portion is a fin shape, or the thickness of the rising portion is The same from the root to the tip, and various variations are assumed.
