Description

Aspects of the present invention relate generally to plumbing units.

2. Description of the Related Art As a mounting structure for a wall member in a plumbing unit, there is known a structure in which the wall member is inserted into and arranged in a wall mounting recess provided on the outer edge of the floor member. In such a configuration, a caulking material is applied to the boundary between the floor member and the wall member in order to prevent the water in the plumbing unit from leaking out of the plumbing unit (Patent Reference 1).

However, since the caulking material is applied after the wall member is assembled to the floor member, the accuracy of the application depends on the construction technique of the on-site builder. That is, if the construction technique of the on-site builder is not sufficient, there is a risk that the caulking material may be forgotten to be applied, or the caulking material may not be applied correctly, and watertightness may not be ensured. Therefore, there is a problem that the watertightness in the plumbing unit cannot be guaranteed by the manufacturer of the floor member or the wall member.

Here, it is conceivable to provide a sealing member between the bottom surface of the wall member and the inner bottom surface of the wall mounting recess. However, the amount of gap between the wall member and the floor member fluctuates due to the influence of the product error of each member, the inclination state of the floor member, and the like. In this case, there is a risk that sufficient pressure will not be applied to the sealing member at locations where there is a large gap between the bottom surface of the wall member and the inner bottom surface of the wall mounting recess, resulting in insufficient sealing performance. Also, in order to ensure the sealing performance, it is conceivable to form the seal member with a large height in consideration of a large gap amount. However, since the wall member is inserted into the wall mounting recess from the inside of the plumbing unit, the sealing member falls from the inside to the outside of the plumbing unit, and there is a risk that the placement of the wall member becomes unstable.

JP 2019-52509 A

The present invention has been made based on recognition of such problems, and an object of the present invention is to provide a plumbing unit that can suppress leakage of water from the inside of the unit to the outside of the unit.

A first invention comprises a floor member having a floor, a wall-mounting recess provided along the outer edge of the floor, a wall member inserted into the wall-mounting recess, the wall-mounting recess and the wall-mounting recess. a seal member for water-tightly sealing a space between the wall-mounting recess and the wall member; , wherein the sealing member includes a deformable member extending upward from the inner bottom surface and deformable by being pressed against the wall member, and an adhesive member provided on the upper surface of the deformable member and having adhesiveness. It is a plumbing unit characterized by having.

According to this plumbing unit, when the wall member is installed on the floor member, it is assumed that the wall member is inserted in an inclined state with respect to the wall mounting recess due to the inclined state of the floor member, the manufacturing tolerance of the wall member, or the like. Also, the deformation of the deformation member can absorb the amount of variation in the gap due to the inclination of the wall member. As a result, the wall member can be accurately attached to the wall mounting recess. Also, the adhesive material provided on the upper surface of the deformable member can effectively seal between the wall member and the wall mounting recess. In this case, the amount of deformation of the deformable member changes even in a portion where the gap between the wall member and the wall mounting recess is large, so that the sealability can be maintained firmly.

As a result, the wall member can be attached to the wall receiving member with high accuracy. In addition, the wall member and the wall receiving member can be effectively sealed by the adhesive material provided on the upper surface of the deformable member. In this case, since the amount of deformation of the deformable member changes even at a portion where the amount of gap between the wall member and the wall receiving member is large, it is possible to maintain the sealing performance firmly. Therefore, the sealing member is excellent in stability and can ensure watertightness even if the amount of clearance between the wall member and the wall receiving member changes.

A third invention is the plumbing unit according to the first or second invention, wherein the vertical thickness dimension of the deformable material is larger than the vertical thickness dimension of the adhesive material. .

According to this plumbing unit, the deformable material can secure a large amount of absorption of the gap between the bottom surface of the wall member and the wall mounting recess or the wall receiving member. As a result, the coating thickness of the adhesive material can be reduced as much as possible, so the cost can be reduced.

FIG. 1 is a perspective view schematically showing a plumbing unit according to the first embodiment.

A plumbing unit 100 shown in FIG. 1 includes a floor member 10 , a wall member 20 and a seal member 30 . The plumbing unit 100 also has a mounting structure 1 for the wall member 20 .

In the example shown in FIG. 1, the plumbing unit 100 is a bathroom. Therefore, the plumbing unit 100 further has a bathtub 200 . Bathtub 200 is installed on bathroom installation surface F via support legs 110 . The plumbing unit 100 is, for example, a unit bath (system bath) for home use. The floor member 10 is, for example, a washroom floor. The plumbing unit 100 may be, for example, a unit bath for a hotel in which a toilet bowl, a bathroom vanity, etc. are mounted on the floor member 10 . The floor member 10 may be the floor of a hotel bathroom or the like. The specific configuration of the plumbing unit 100 is not limited to the example in FIG. 1, and can be changed as appropriate. For example, the plumbing unit 100 may be a shower room or the like that does not have a bathtub 200 .

The floor member 10 constitutes the floor surface of the plumbing unit 100 . The floor member 10 is formed in the shape of a shallow vessel (bread-shaped) with its peripheral portion bent upward, and has waterproofness to prevent hot water from leaking out of the unit. The floor member 10 is installed on the bathroom installation surface F via a support leg 110 having a structure whose height can be adjusted by rotating a bolt portion. The floor member 10 has a floor portion 11 and a wall mounting recess 12 provided on the outer peripheral side of the floor portion 11 and on which the wall member 20 is mounted.

The wall member 20 is inserted into the wall mounting recess 12 of the floor member 10 and extends upward from the floor member 10 . The wall member 20 is, for example, a door support frame 21 that supports a door serving as an entrance to the plumbing unit 100 . Further, the wall member 20 is, for example, a first surface portion 22 facing the door support frame 21 . Moreover, the wall member 20 is the 2nd surface part 23 which faces the bathtub 200, for example. The wall member 20 is a panel 24 positioned between the door support frame 21 and the bathtub 200 or between the first surface portion 22 and the bathtub 200, for example. That is, the wall member 20 is a side wall of the plumbing unit 100 rising from the outer edge of the floor member 10 . The wall member 20 has a steel plate 20a exposed inside the plumbing unit 100 and a base material 20b (for example, a gypsum board) fixed to the back side of the steel plate 20a.

2 is a cross-sectional view of the floor member and the wall member in FIG. 1 as viewed in the direction of arrows AA.
FIG. 3 is a cross-sectional view showing a state in which the wall member is inserted into the wall mounting recess.

The floor member 10 has a floor portion 11 and a wall mounting recess 12 provided along the outer edge of the floor portion 11 . The floor portion 11 has a floor portion 11b on the side of the upper surface 11a. The floor surface portion 11b is a portion that is exposed inside the plumbing unit 100 and that is actually used by the user as a washing area.

The wall mounting recess 12 is provided at the peripheral end of the floor 11 and is formed in a recessed shape with an open top. The wall mounting recess 12 is provided, for example, along the entire three sides that are not adjacent to the bathtub 200 among the four sides (outer edges) of the floor 11 . The wall mounting recess 12 has an inner bottom surface 13 recessed below the upper surface 11 a of the floor portion 11 and an inner side surface 14 extending upward from the inner bottom surface 13 .

The inner bottom surface 13 extends along the outer edge of the floor portion 11 at a position one step lower than the upper surface 11 a of the floor portion 11 . The inner bottom surface 13 is a stepped surface having a step in the vertical direction due to the regulation portion 15 . The restricting portion 15 is provided on the side of a seal member 30, which will be described later. The restricting portion 15 restricts sinking of the wall member 20 by coming into contact with the wall member 20 . The restricting portion 15 may be provided along the seal member 30, or may be provided in plurality at predetermined intervals in the lengthwise direction of the wall-mounted concave portion 12. As shown in FIG. Further, the restricting portion 15 may be provided integrally with the wall mounting recess 12 or may be provided separately. Furthermore, the restricting portion 15 may protrude from the inner surface 14 of the wall-mounting recess 12 . That is, the restricting portion 15 can restrict sinking of the wall member 20 and may be provided at any position within the wall mounting recess 12 as long as it does not interfere with the sealing member 30 .

When the wall member 20 is installed in the wall-mounting recess 12, the regulating portion 15 may cause a portion of the wall member 20 to be placed in the wall-mounting recess 12 more than expected due to the inclination of the floor member 10, the manufacturing tolerance of the wall member 20, and the like. To restrict sinking of a wall member 20 even if it sinks. Therefore, the restriction portion 15 can suppress deformation of the deformation member 31 of the seal member 30, which will be described later, exceeding the allowable deformation amount.

The inner surface 14 has a first inner surface 14a located on the floor 11 side and a second inner surface 14b facing the first inner surface 14a. The first inner side surface 14 a rises from the end portion of the inner bottom surface 13 on the floor section 11 side toward the upper surface 11 a of the floor section 11 . On the other hand, the second inner surface 14 b rises from the end of the inner bottom surface 13 opposite to the floor 11 . The wall mounting recess 12 is set so that the dimension between the first inner side surface 14 a and the second inner side surface 14 b corresponds to the thickness dimension of the wall member 20 . Moreover, the depth dimension from the upper surface 11a of the floor portion 11 to the inner bottom surface 13 of the wall mounting recess 12 is set so that the wall member 20 can be stably erected from the floor member 10 .

Next, the sealing member 30 will be described.

The seal member 30 is provided inside the wall mounting recess 12 . The seal member 30 extends continuously in the length direction of the wall mounting recess 12 . The seal member 30 is sandwiched between the wall mounting recess 12 and the wall member 20 to watertightly close the space between the wall mounting recess 12 and the wall member 20 . That is, the sealing member 30 suppresses (seals) leakage of water from the inside of the plumbing unit 100 to the outside through the wall-mounted recess 12 . The seal member 30 has a deformable material 31 and an adhesive material 35 .

The deformation member 31 is provided along the inner bottom surface 13 of the wall-mounting recess 12 . That is, the deformation member 31 is provided so as to extend in the length direction of the inner bottom surface 13 . The deformation member 31 is made of a resin material such as plastic or elastomer, and can be deformed by being pressed against the wall member 20 . Deformable in this case includes both plastic deformation and elastic deformation. Moreover, the deformation of the deformable member 31 includes both the case where the shape of the deformable member 31 is deformed as a whole and the case where the material itself of the deformable member 31 is deformed.

The deformation member 31 is formed by bending a thin plate, for example. The deformation member 31 has a hollow interior and is formed in a gate shape extending upward from the inner bottom surface 13 . Specifically, the deformation member 31 includes an inner leg portion 32 positioned on the floor portion 11 side and extending in the vertical direction, an outer leg portion 33 facing the inner leg portion 32 and extending in the vertical direction, and an inner leg portion 32 and a connecting portion 34 connecting between and the outer leg portion 33 . The deformable member 31 is set such that the vertical thickness dimension H1 is positioned above the height of the restricting portion 15 . That is, the connecting portion 34 is positioned above the restricting portion 15 (on the opening side of the wall-mounting recessed portion 15).

The inner leg portion 32 has an upper leg portion 32a extending downward from the connecting portion 34 and a bent portion 32b bent from the lower end of the upper leg portion 32a. The bent portion 32 b extends from the lower end of the upper leg portion 32 a toward the first inner side surface 14 a (floor portion 11 ), and the lower end is fixed to the inner bottom surface 13 of the wall-mounted concave portion 12 . The bent portion 32b may be bent from the lower end of the upper leg portion 32a toward the outer leg portion 33 side. On the other hand, the outer leg portion 33 has its lower end fixed to the inner bottom surface 13 of the wall mounting recess 12 and extends straight toward the connecting portion 34 .

Thus, when the deformable member 31 is pressed from above by the wall member 20, the deformable member 31 is deformed such that the inner leg portion 32 sinks downward first. Therefore, when the wall member 20 is inserted into the wall mounting recess 12, the seal member 30 is deformed so as to fall toward the floor 11 (the plumbing unit 100). As a result, the seal member 30 can be positioned between the wall mounting recess 12 on the side of the floor 11 and the wall member 20, so that stable sealing performance can be maintained.

The connection portion 34 of the deformable member 31 has an uneven top surface 34a. In this case, the entire connecting portion 34 may be formed in an uneven shape, or only the upper surface 34a may be formed in an uneven shape. That is, at least the upper surface 34a of the connecting portion 34 should be formed in an uneven shape. An adhesive material 35 is adhered to the uneven upper surface 34a. Thereby, the contact surface (bonding surface) between the upper surface 34a of the deformation member 31 and the adhesive material 35 can be enlarged. Moreover, when the adhesive material 35 is pressed against the wall member 20 , it is possible to suppress the horizontal sliding of the adhesive material 35 with respect to the deformation member 31 . This can prevent the adhesive material 35 from peeling off from the deformable material 31 . In addition, in the example shown in FIG. 3, the connecting portion 34 is formed in a curved shape, but the present invention is not limited to this.

The adhesive material 35 is provided on the upper surface 34 a of the deformable material 31 . This adhesive material 35 has adhesiveness and elasticity. The adhesive material 35 is made of, for example, a pressure-sensitive adhesive. The adhesive material 35 does not dry completely even after a long period of time, for example, and is a material that is always adhesive. Therefore, it is completely different from a so-called adhesive that dries completely over time and loses adhesiveness (adhesiveness approaches zero limitlessly).

Moreover, since the adhesive material 35 has elasticity, even if the wall member 20 is removed from the wall mounting recess 12, the elasticity restores the original shape. Therefore, the wall member 20 can be attached to the adhesive material 35 again. That is, the adhesive material 35 can be detachably attached to the wall member 20 . Note that the adhesive material 35 may be, for example, a gel (gel substance) having adhesiveness and elasticity.

Thus, the seal member 30 has a two-layer structure of the deformable material 31 and the adhesive material 35 . In this case, as shown in FIG. 3, the vertical thickness dimension H1 of the deformable material 31 is larger than the vertical thickness dimension H2 of the adhesive material 35 (H1>H2). The thickness dimension H1 of the deformable material 31 and the thickness dimension H2 of the adhesive material 35 are set through experiments and simulations according to the depth dimension of the wall mounting recess 12 and the specifications of the wall member 20, for example. As a result, the deformation member 31 can secure a large amount of absorption of the gap between the wall member 20 and the wall-mounting recess 12 . As a result, the coating thickness of the adhesive material 35 can be reduced as much as possible, so the cost can be reduced.

The caulking material 40 is provided at the corner (boundary) between the floor 11 and the wall member 20 . The caulking material 40 is applied on site after the wall member 20 is inserted into the wall mounting recess 12 . The caulking material 40 is made of silicone, for example, and prevents water from entering the wall mounting recess 12 from the floor 11 .

The mounting structure of the wall member according to the present embodiment has the configuration as described above. Next, the work of assembling the wall member 20 into the wall mounting recess 12 will be described.

First, as shown in FIG. 3 , the wall member 20 is inserted into the wall mounting recess 12 of the floor member 10 from the interior of the plumbing unit 100 . After that, the caulking material 40 is applied to the corner between the floor 11 and the wall member 20 .

Here, since the coating work of the caulking material 40 is performed after the wall member 20 is assembled to the floor member 10, the accuracy thereof is left to the construction technique of the builder on site. That is, if the construction technique of the on-site builder is not sufficient, there is a risk that the caulking material 40 may be forgotten to be applied, or the caulking material 40 may not be applied correctly, and watertightness may not be ensured. .

Therefore, a configuration in which a sealing member is provided between the wall member 20 and the wall mounting recess 12 is conceivable. However, the amount of clearance between the wall member 20 and the wall mounting recess 12 fluctuates due to the influence of the product error of each member, the inclination state of the floor member 10, and the like. In this case, there is a risk that sufficient pressure will not be applied to the sealing member at locations where the clearance between the wall member 20 and the wall mounting recess 12 is large, resulting in insufficient sealing performance. Also, in order to ensure the sealing performance, it is conceivable to form the seal member with a large height in consideration of a large gap amount. However, since the wall member 20 is inserted into the wall mounting recess 12 from the inside of the plumbing unit 100, the seal member falls outward, and there is a possibility that the arrangement of the wall member 20 becomes unstable.

Therefore, in this embodiment, a seal member 30 having a deformable material 31 and an adhesive material 35 is provided in the wall mounting recess 12 of the floor member 10 . This seal member 30 is provided in the wall mounting recess 12 at the factory. As a result, when the wall member 20 is inserted into the wall-mounted recess 12, watertightness can inevitably be obtained between the wall member 20 and the wall-mounted recess 12. As shown in FIG. Therefore, even if the application work of the caulking material 40 on site is incomplete, the sealing member 30 can prevent water from leaking from the interior of the plumbing unit 100 to the exterior.

The seal member 30 has a two-layer structure of a deformable material 31 and an adhesive material 35 . The deformation member 31 is deformed in height (thickness) by being pressed by the wall member 20 , and can absorb the amount of gap between the wall mounting recess 12 and the wall member 20 . Therefore, the adhesive material 35 can obtain an appropriate compressive force from the wall member 20 regardless of the size of the gap.

Further, the vertical thickness dimension H1 of the deformable material 31 is larger than the vertical thickness dimension H2 of the adhesive material 35 (H1>H2). As a result, the deformation member 31 can secure a large amount of absorption of the gap between the wall member 20 and the wall-mounting recess 12 . As a result, the coating thickness of the adhesive material 35 can be reduced as much as possible, so the cost can be reduced.

Moreover, the upper surface 34a of the deformation member 31 is formed in an uneven shape. Thereby, the contact surface (bonding surface) between the deformable material 31 and the adhesive material 35 can be enlarged. Further, as shown in FIG. 3, the wall member 20 is inserted obliquely into the wall mounting recess 12 from the indoor side of the plumbing unit 100 . Therefore, the adhesive material 35 is horizontally pressed from the wall member 20 toward the second inner surface 14b. Since the uneven upper surface 34 a of the deformable member 31 can suppress this horizontal pressing force, it is possible to suppress the horizontal sliding of the adhesive member 35 on the deformable member 31 . This can prevent the adhesive material 35 from peeling off from the deformable material 31 .

In addition, a restricting portion 15 is further provided on the side of the sealing member 30 . The restricting portion 15 restricts sinking of the wall member 20 by contacting the wall member 20 . As a result, even when part of the wall member 20 sinks into the wall mounting recess 12 more than expected due to the inclination of the floor member 10 or manufacturing tolerances of the wall member 20, the restricting portion 15 prevents the wall member 20 from Control subduction. Therefore, application of an excessive load to the deformation member 31 can be suppressed. In other words, it is possible to suppress deformation of the deformation member 31 exceeding the allowable deformation amount.

The deformation member 31 includes an inner leg portion 32 positioned on the floor portion 11 side and extending in the vertical direction, an outer leg portion 33 facing the inner leg portion 32 and extending in the vertical direction, the inner leg portion 32 and the outer leg portion. a connecting portion 34 connecting between the inner leg portion 32 and the inner leg portion 32; the inner leg portion 32 includes an upper leg portion 32a extending downward from the connecting portion 34; have.

When the wall member 20 is installed on the floor member 10, the wall member 20 is inserted in a state in which the upper portion is inclined toward the indoor side of the plumbing unit 100. - 特許庁At this time, the bent portion 32b of the deformation member 31 is bent, so that the inner leg portion 32 of the seal member 30 is deformed before the outer leg portion 33 is deformed. As a result, the seal member 30 is deformed so as to collapse toward the room. The adhesive material 35 adheres to the steel plate 20a of the wall member 20 and the first inner side surface 14a of the wall-mounting recess 12, thereby sealing the gap between the wall member 20 and the wall-mounting recess 12 in a watertight manner. Thereby, the sealing member 30 can maintain a stable sealing performance.

In addition, when the sealing member 30 is designed to fall toward the interior side, it is preferable to position the regulating portion 15 between the sealing member 30 and the second inner side surface 14 b of the wall-mounting recess 12 . That is, it is preferable that the restricting portion 15 be positioned on the side opposite to the direction in which the sealing member 30 falls. As a result, the sealing member 30 can be prevented from interfering with the restricting portion 15, so that the wall member 20 can be stably arranged in the wall mounting recess 12, and a stable sealing property can be ensured. can.

The wall receiving member 50 is formed in a concave shape with an upper opening, and the wall member 20 is inserted therein. That is, the wall member 20 is inserted into the wall mounting recess 12 via the wall receiving member 50 . Further, the wall receiving member 50 is provided with a sealing member 60 and a restricting portion 55 . As a result, the seal member 60 seals the space between the wall receiving member 50 and the wall member 20 in a watertight manner. Further, the restricting portion 55 restricts sinking of the wall member 20 .

The wall receiving member 50 has a bottom surface portion 51 that contacts the inner bottom surface 13 of the wall-mounting recess 12 and a side surface portion 52 that extends upward from the bottom surface portion 51 and faces the inner surface 14 of the wall-mounting recess 12 . ing. Moreover, the side portion 52 of the wall receiving member 50 has a first side portion 53 located on the floor portion 11 side and a second side portion 54 facing the first side portion 53 . The first side surface portion 53 has a rising portion 53a that rises upward from the bottom surface portion 51, and a projecting portion 53b that projects from the upper end of the rising portion 53a toward the second side surface portion 54 side.

The restricting portion 55 protrudes upward from the bottom portion 51 . This restricting portion 55 has the same configuration as the restricting portion 15 according to the first embodiment. The restricting portion 55 can be provided at any position inside the wall receiving member 50 . That is, the restricting portion 55 may protrude from the side portion 52 of the wall receiving member 50 .

In addition, when the sealing member 60 is designed to fall toward the interior side, it is preferable to position the restricting portion 55 between the sealing member 60 and the second side portion 54 of the wall receiving member 50 . That is, it is preferable that the restricting portion 55 be positioned on the side opposite to the direction in which the seal member 60 falls. As a result, the sealing member 60 can be prevented from interfering with the regulating portion 55, so that the wall member 20 can be stably arranged on the wall receiving member 50 and a stable sealing property can be ensured. can.

The side surface portion 52 has a height dimension smaller than the depth dimension of the wall mounting recess 12 . The first side surface portion 53 faces the first inner side surface 14 a of the wall mounting recess 12 .
