There has also been proposed a bathroom floor structure in which a waterproof putty is filled between the bath floor body and the waterproof baseboard.
Japanese Utility Model Publication No. 60-172903

  The bathroom floor structure described in Patent Document 1 uses waterproof baseboards and corner joints in order to close a gap between a wall base and a bath floor body constituting the floor. Since these are members having a complicated structure, the construction cost is increased. In addition, it is necessary to cut the bus floor body and waterproof baseboard according to the dimensions of the room where the bathroom is to be constructed, and it takes time to fix the waterproof baseboard to the bath floor body. Is not very good. Furthermore, the waterproof performance between the bath floor main body and the waterproof baseboard depends on the finish of the waterproof putty filling work at the construction site. In other words, since it largely depends on the skill level of the operator, there is a drawback that waterproof performance is not always guaranteed.

  In view of the above-described conventional problems, the present invention provides a novel means for constructing a waterproof structure in a room constructed in a space surrounded by a base wall surface. The waterproof material adopted by the present invention is characterized by a connectable linear member and a corner member, and each linear member and the corner member are provided between the base wall surface and the wall finishing material attached to the surface thereof. And a drainage guide portion that is positioned so as to reach the inner region of the waterproof flooring that is installed on the floor surface.

  The material of the waterproof material, such as metal plate, synthetic resin plate, synthetic resin sheet, etc., which is relatively thin, excellent in strength and water resistance, has no water permeability and water absorption, and preferably has water repellency Is done.

  When the waterproofing material is configured so that the ends of the linear member and the corner member are overlapped and connected, the drainage passage may be formed in the overlapping region of the linear member and the corner member. preferable.

  Further, the waterproof material is composed of a straight member, a corner member, and a connecting material for connecting the end portions of the straight member and the corner member, and the connecting material is disposed between the base wall surface and the wall finishing material. And a drainage guide portion positioned so as to reach the inner region of the waterproof flooring installed on the floor surface.

  In this case, it is desirable to set so that a drainage passage is formed at a joint portion between the linear member or corner member of the waterproof material and the connecting material.

  The present invention provides a waterproof structure in a room constructed in a space surrounded by a base wall surface using the waterproof material, characterized in that a waterproof floor is provided on the floor surface of the space. The above-mentioned waterproof material is disposed so as to cover the gap between the base wall surface and the waterproof floor material, and the straight member and the corner member of the waterproof material have the rising portion formed on the upper end side as the base wall surface. And the wall finishing material mounted on the surface of the waterproof flooring, and the drainage guide portion is positioned so as to reach the inner region of the waterproof flooring.

  The waterproof structure is applied when a bathroom or a shower room is constructed in a room surrounded by a base wall surface made of a frame wall, a wall base material, or the like, around a floor such as a dirt floor or a foundation. The waterproof floor material is typically a waterproof pan made of FRP, but a floor material made of metal or synthetic resin can also be used. Examples of the wall finishing material include tile panels, metal panels, synthetic resin panels, and FRP panels. An adhesive is the simplest means for attaching the waterproof material to the base wall surface and the waterproof floor material.

  Since the waterproof material according to claim 1 of the present invention is configured by combining a linear member and a corner member that can be connected, even if the specifications of the size and shape of the room to be constructed are variously different, It is possible to cope with a member. Accordingly, it is possible to easily cope with a change in the specification of the room shape and dimensions at the site. In addition, since both the straight member and the corner member are provided with the rising portion and the drainage guide portion, the configuration can be simplified.

  Since the waterproof material according to claim 2 of the present invention is configured so that the end portions of the linear member and the corner member are overlapped with each other, a dimensional error is caused at the construction site by adjusting the overlap amount. Even if it occurs, it can be dealt with easily. Further, since the drainage passage is formed in the overlapping region of the linear member and the corner member, the water that has entered the overlapping region can be reliably discharged.

  Since the waterproof material according to claim 3 of the present invention employs a configuration in which the linear member and the corner member are connected by the connecting material, the structure required for the connection may be provided in the connecting material. It is possible to simplify the configuration.

  Since the waterproof material which concerns on Claim 4 of this invention formed the drainage channel in the junction part of a linear member or a corner member, and a connection material, the discharge | release of the water which permeated the said junction part is reliable. Further, by providing the drainage passage on the connecting material side, the shape of which is likely to be complicated, it can be avoided that the configuration of the straight member and the corner member is complicated.

  In the waterproof structure according to the present invention using the waterproof material, the rising portion of the waterproof material is disposed between the base wall surface and the wall finishing material mounted on the surface thereof, and the drainage guide portion is disposed on the inner area of the waterproof floor material. Therefore, the mounting operation is simple. With the waterproof material, it is possible to reliably guide the water used indoors and the water generated between the base wall surface and the wall finishing material onto the waterproof floor material and prevent it from entering the lower space of the waterproof floor material. It is possible to prevent the lower space of the waterproof flooring from becoming a humid environment and the floor surface of the foundation or the like from getting wet.

  Moreover, since the structure which does not form a clearance gap between a base wall surface and the wall finishing material with which the surface is mounted | worn can be employ | adopted, the space volume of the bathroom etc. to construct can be set large. Furthermore, if the length of the lower end of the waterproof material is sufficiently secured, even if a waterproof flooring with a small size is used, the waterproof function is secured by covering the gap between the base wall surface and the waterproof flooring. I can do it. This is advantageous, for example, when the size of the waterproof flooring that can be carried in is limited due to the dimensional relationship of the carry-in entrance of a room where a bathroom or the like is to be constructed. Moreover, even if a waterproof flooring having a small size is used in the structure of the present invention, it is not necessary to change the position of the wall finishing material, so that the volume of the constructed room is hardly reduced.

  As shown in FIG. 1, the present invention is applied to a case where a bathroom Y, a shower room, or the like is constructed in a room surrounded by a base wall surface W composed of a frame wall or a wall base material 2. In order to construct the waterproof structure according to the present invention, first, as shown in FIG. 1A, a waterproof flooring 10 made of a waterproof pan or the like is placed on a floor surface F made of a foundation 1 or the like. The waterproof flooring 10 is composed of a flat portion 10a and an upright portion 10b formed at the peripheral edge thereof.

  Subsequently, the waterproof material 5 according to the present invention is disposed so as to cover the gap between the base wall surface W and the waterproof flooring 10. The waterproof material 5 of this example is composed of a combination of a linear member 50 and corner members 51, 52 made of a metal plate, a synthetic resin plate, a synthetic resin sheet or the like (see FIG. 2). That is, as shown in FIG. 1B, in accordance with the planar shape of the room (underlying wall surface W), straight members 51 are arranged at the straight portions, and corner members 51 and 52 are arranged at the corner portions, and these are connected. . Further, as shown in the example, when the planar shape of the room has an inner corner portion and an outer corner portion, the inner corner member 51 as shown in FIG. An outer corner member 52 as shown is prepared.

  The straight member 50, the inner corner member 51, and the outer corner member 52 constituting the waterproof material 5 are all provided with a rising portion 5b on the upper end side, and have a downward slope toward the waterproof flooring 10 on the lower end side. A drainage guide portion 5a is formed. Moreover, the drooping portion 6 may be formed at the lower end of the drainage guide portion 5a as shown in FIG. 2A, or the drooping portion 6 may be omitted as shown in FIG.

  For example, as shown in FIG. 3, the linear member 51 and the corner members 51 and 52 are connected to each other by overlapping the end portions of the linear member 51 and the corner members 51 and 52 via the water-stopping packing 21 or the like, A means using an adhesive is conceivable.

  As for the linear member 50, a necessary type of a predetermined length corresponding to the dimension of the room to be constructed can be prepared. However, one type or a minimum necessary type of the long member is prepared, and the room size is set at the site. It is also possible to cut together. In this case, it is possible to cope with a dimensional error of the room or a slight specification change by using an overlapping region formed in a connecting portion between the linear member 50 and the corner member 51 (52). That is, since the dimensional accuracy when manufacturing the linear member 50 and the dimensional accuracy when cutting are not so severely required, manufacturability and workability are improved.

  The waterproofing material 5 has the rising portion 5b attached to the base wall surface W with an adhesive, and a wall finish material 3 such as a tile panel or metal panel is mounted on the base wall surface W, and the rising portion 5 5b is sandwiched between them. On the other hand, the drooping portion 6 at the lower end of the drainage guide portion 5 a is set so as to be located in the inner region of the waterproof flooring 10.

  The waterproof structure constructed in this way allows water used indoors or water generated due to condensation between the base wall surface W and the wall finishing material 3 to enter the lower space of the waterproof flooring 10. Therefore, it is possible to prevent the lower space of the waterproof flooring 10 from becoming a humid environment and the floor surface of the foundation 1 and the like from getting wet. Since the drainage guide portion 5a having a downward slope is formed in the waterproof material 5, and the hanging portion 6 is provided at the lower end thereof, the water on the waterproof material 5 can be reliably guided onto the waterproof flooring 10. . The space S below the drainage guide portion 5a, that is, the space S between the standing portion 10b of the waterproof flooring 10 and the base wall surface W can be used as a space for installing equipment such as piping.

  By the way, since the waterproof structure according to the present invention adopts a configuration in which no gap is provided between the base wall surface W and the wall finishing material 3, the space volume of the bathroom Y or the like to be constructed can be set large. Moreover, for example, even when only a waterproof flooring with a small size can be used because the entrance of the room is narrow, there is no need to change the position of the wall finishing material 3, so that the volume of the room Y to be constructed is almost reduced. And the waterproof function is not impaired.

  4 to 7 show other examples relating to a connecting structure of the linear member 50 and the corner member 51 (52) constituting the waterproof material 5. FIG. FIG. 4 shows an example in which a vertical drainage channel 30 communicating in a substantially vertical direction is provided in the overlapping region of the end portion of the linear member 50 joined by the waterproof tape 20 and the end portion of the corner member 51 (52). Is. In this example, the drainage channel 30 is formed between the end portion on the straight member 50 side by providing the concave-convex structure 31 made of continuous mountain-shaped ridges as shown at the end portion on the corner member 51 side. Was set as follows. The uneven structure 31 is preferably provided at the end on the corner member 51 (52) side. This is because the end portion of the linear member 50 may be cut for dimensional correction at the site. Therefore, when there is no possibility of being cut, it is not hindered to provide the concavo-convex structure 31 at the end on the straight member 50 side.

  As shown in FIG. 5, it is also possible to provide the vertical drainage channel 30 between the straight member 50 by forming a groove structure at the end of the corner member 51 (52).

  As shown in FIG.6 and FIG.7, the structure which interposes the connection material 60 between the linear member 50 and the corner member 51 (52), and connects both is also possible. In this case, the end portions of the straight members 50 and the end portions of the corner members 51 (52) are joined together by the connecting member 60 and the waterproof tape 20, respectively, so that they are connected. Further, it is possible to provide the vertical drainage channel 31 between the linear member 50 and the corner member 51 (52) in which the concavo-convex structure 31 is formed in the connecting member 60. As in the present example, by forming the concavo-convex structure 31 on the connecting member 60 side, the end structures of the linear member 50 and the corner member 51 (52) can be simplified.

  Further, as shown in FIG. 7, the vertical drainage channel 30 is provided by forming a concave groove as shown in the connecting member 61 that connects the end of the linear member 50 and the end of the corner member 51 (52). Configuration is also conceivable.

  As shown in FIG. 8, the waterproof structure according to the present invention is provided with an inclined surface portion 10 c that is inclined upward toward the base wall surface W on the standing portion 10 b formed on the peripheral edge portion of the waterproof flooring 10, and this inclined surface portion. It can also be set as the structure which overlaps the drainage guide part 5a of the waterproof material 5 to 10c. In this example, as in the case where the bathroom Y is constructed on the second floor, the waterproof flooring 10 is installed on the floor base material 7 such as a beam supported by the bracket 6 fixed to the housing.

  Further, as shown in FIG. 9, the entire standing portion 10 b of the waterproof flooring 10 can be an inclined surface portion having an upward gradient toward the base wall surface W.

  As described in this example, the drainage guide portion 5a of the waterproof material 5 is mounted on the inclined surface portion 10c of the waterproof flooring 10 so as to obtain the following advantages. First, since the load of the waterproofing material 5 is supported by the waterproofing flooring 10, the mounting state is stabilized, and when both are fixed with an adhesive, the bonding area can be widened, so the mounting is strong and resistant to changes over time. You can build a structure. Secondly, as long as the overlapping state of the waterproof material 5 and the waterproof flooring 10 is maintained, the arrangement of the waterproof flooring 10 can be moved without impairing the waterproof function. The installation work of the material 10 becomes easy. Third, by providing the inclined surface portion 10c in the waterproof flooring 10, an installation space S such as piping is automatically formed between the waterproof flooring 10 and the base wall surface W.

  When the drainage guide portion 5a of the waterproof material 5 is superimposed on the waterproof flooring 10, as shown in FIG. 10, a horizontal portion 10d is formed on the standing portion 10b of the waterproof flooring 10, and the lower end side of the waterproofing material 5 is formed thereon. A configuration in which the drainage guide portion 5a formed horizontally is mounted is also possible. As shown in FIG. 10 (A), a hanging portion 6 is formed at the tip of the drainage guide portion 5 a of the waterproof material 5, so that water falling on the waterproof material 5 can be easily guided to the waterproof floor material 10. Although it is preferable, as shown in FIG.

  In this embodiment, since the drainage guide portion 5a at the lower end of the waterproof material 5 is supported by the horizontal portion 10d of the waterproof flooring 10, the support state is extremely stable. Moreover, compared with the said embodiment which forms the inclined surface parts 5a and 10c in the waterproof material 5 and the waterproof flooring 10, the space volume of a room becomes large in this example supported in a horizontal state. Moreover, it is possible to employ a configuration in which the horizontal drainage guide portion 5a of the waterproof material 5 supported by the waterproof flooring 10 is used as an article mounting table as desired.
