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 seal member has one side provided on the inner surface and the other side extending toward the interior of the wall-mounting recess, and is deformable by being pressed by the wall member; and an adhesive material having adhesiveness provided on the upper surface of the plumbing unit.

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. Additionally, the seal member extends from the inner surface of the wall-mounting recess. Therefore, the same sealing member can be used for various wall mounting recesses having different depths by simply adjusting the mounting height of the sealing member. Therefore, since the thickness of the sealing member can be reduced, the stability is excellent, and watertightness can be ensured even if the gap between the wall member and the wall mounting recess varies.

A second aspect of the present invention is a floor member having a floor, a wall-mounting recess provided along the outer edge of the floor, a wall-receiving member provided in the wall-mounting recess, and the wall-receiving member. a wall member to be inserted into the wall-mounting recess through a wall-mounting recess, and a sealing member that seals a space between the wall-receiving member and the wall member in a water-tight manner, wherein the wall-mounting recess is positioned from the top surface of the floor. and an inner bottom surface extending upward from the inner bottom surface. and a side face portion facing the inner side face of the wall-mounting recess, wherein one side of the sealing member is provided on the side face portion and the other side extends toward the interior of the wall receiving member. 1. A plumbing unit, comprising: a deformable member that can be deformed by being pressed against the wall member; and an adhesive member provided on an upper surface of the deformable member and having adhesiveness.

According to this plumbing unit, when the wall member is installed on the floor member, even if the wall member is inserted in an inclined state with respect to the wall receiving member due to the inclination state of the floor member, the manufacturing tolerance of the wall member, etc. 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 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. Additionally, the seal member extends from the side portion of the wall receiving member. Therefore, the same sealing member can be used for various wall mounting recesses having different depths, simply by adjusting the mounting position of the side surface. Therefore, since the thickness of the sealing member can be reduced, the stability is excellent, and watertightness can be ensured even if the gap between the wall member and the wall receiving member changes.

In a third aspect of the invention, in the first or second aspect, the deformation member is elastically deformable in the vertical direction with the one side serving as a fixed end and the other side serving as a free end. The plumbing unit is characterized in that the thickness dimension in the direction is smaller than the thickness dimension in the vertical direction of the adhesive material.

According to this plumbing unit, it is possible to adjust the pressing force between the wall member and the adhesive material by elastic deformation of the deformable material. As a result, the adhesive force of the adhesive material can achieve a good balance between stopping water and removing the wall member. Therefore, since the adhesive material of the sealing member is excellent in releasability from the wall member, it is possible to improve the workability of attaching and detaching the wall member.

A fourth invention is the plumbing unit according to any one of the first to third inventions, wherein the upper surface of the deformation member is formed in an uneven shape.

According to this plumbing unit, the contact surface (bonding surface) between the deformable material and the adhesive material can be enlarged. Therefore, it is possible to suppress the peeling of the adhesive material from the deformable material when the wall member is removed. Moreover, when the adhesive material is pressed against the wall member, it is possible to prevent the adhesive material from sliding in the horizontal direction with respect to the deformable material. As a result, it is possible to prevent the adhesive material from peeling off from the deformable material.

A fifth invention is characterized in that, in any one of the first to fourth inventions, the deformable member has an upper inclined portion in which the other side is inclined upward toward the opening side of the wall-mounting recess. It is a plumbing unit.

According to this plumbing unit, even if the adhesive force of the adhesive material is weakened in order to increase the releasability between the wall member and the adhesive material when the wall member is removed, the upward inclination of the deformable material when the wall member is attached is minimized. Since the urging force of the portion is increased, it is possible to suppress the peeling of the adhesive material from the deformable material. Further, when the wall member is installed on the floor member, the mounting work is usually performed from the inside of the plumbing unit. Therefore, the wall member is inserted into the wall-mounting recess with the upper part inclined toward the inside of the plumbing unit. be. Therefore, when the adhesive material is pressed against the wall member, it is possible to suppress the horizontal sliding of the adhesive material with respect to the deformable material. As a result, it is possible to prevent the adhesive material from peeling off from the deformable material.

In a sixth aspect based on the fifth aspect, the deformable member has a downwardly inclined portion with one side serving as a fixed end and downwardly inclined, and an upwardly inclined portion from a tip of the downwardly inclined portion with the other side being a free end. It is a plumbing unit characterized by having the above-mentioned upward inclination part formed.

According to this plumbing unit, when the downwardly inclined portion is pressed against the wall member, the stress applied to the fixed end can be reduced, so the life of the deformable member can be improved. On the other hand, the upward inclined portion can prevent the adhesive material pressed by the wall member from peeling off from the deformable material when the wall member is attached to the floor member.

A seventh invention is the plumbing unit according to the first invention, wherein the deformation member is integrally formed on the inner side surface of the wall-mounted recess.

According to this plumbing unit, since the deformable member is integrated with the wall mounting recess, the strength of the fixed end of the deformable member can be improved.

An eighth invention is the plumbing unit according to the second invention, wherein the deformation member is integrally formed with the side surface portion of the wall receiving member.

According to this plumbing unit, since the deformable member is integrated with the wall receiving member, the strength of the fixed end side of the deformable member can be improved.

In a ninth aspect based on the second or eighth aspect, the side portion of the wall receiving member includes a first side portion located on the floor portion side and a second side portion facing the first side portion. and, the first side surface portion has a rising portion rising upward from the bottom surface portion, and a projecting portion projecting from the upper end of the rising portion toward the second side surface portion, The deformable material extends from the rising portion toward the second side surface portion, and the adhesive material forms a gap between the rising portion and the wall member when the wall member is not inserted into the wall mounting recess. It is a plumbing unit characterized by being provided in the deformable member with

According to this plumbing unit, the adhesive material can be inserted into the space between the wall member and the rising portion, so that the wall member can be arranged at a predetermined position in the wall mounting recess. Moreover, since the adhesive closes the space between the wall member and the rising portion, watertightness can be effectively ensured.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same reference numerals are given to the same constituent elements, and detailed description thereof will be omitted as appropriate.
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 explained.

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 surface 14 of the wall-mounting recess 12 . That is, the deformation member 31 is provided so as to extend in the longitudinal direction of the inner surface 14 . 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 of this embodiment is elastically deformable.

The deformation member 31 is formed of, for example, a thin plate material, and is provided at a position with a height dimension L from the inner bottom surface 13 of the wall mounting recess 12 . The height dimension L is preferably set above the height of the restricting portion 15, for example. That is, since the deformable member 31 is pressed from above by the wall member 20 , it is preferable that the deformable member 31 is provided above the restricting portion 15 (on the opening side of the wall-mounting recessed portion 12 ). In addition, if the upper surface of the adhesive material 35 , which will be described later, is positioned above the restricting portion 15 , the deformable material 31 is pressed through the adhesive material 35 . In other words, the height dimension L of the deformation member 31 is set to a height such that it is pressed by the wall member 20 and elastically deformed downward.

The deformable member 31 has one side 31 a provided on the inner side surface 14 and the other side 31 b extending toward the interior of the wall-mounting recess 12 . Specifically, the deformation member 31 extends straight from the first inner surface 14a toward the second inner surface 14b. In this case, the deformation member 31 has a fixed end on one side 31a (first inner surface 14a side) and a free end on the other side 31b (second inner surface 14b side).

Thereby, the deformation member 31 can be elastically deformed in the vertical direction. As shown in FIG. 3, the deformation member 31 is pressed by the wall member 20 and is elastically deformed so as to exert an upward biasing force. Therefore, when the wall member 20 is inserted into the wall mounting recess 12 , the other side 31 b (free end side) of the deformation member 31 is pressed toward the inner bottom surface 13 . When the wall member 20 is removed from the wall mounting recess 12, the deformation member 31 is restored to its original state (the state shown in FIG. 3) by the biasing force. In this case, the deformation member 31 is formed integrally with the inner side surface 14 (first inner side surface 14 a ) of the wall mounting recess 12 . As a result, the deformation member 31 is integrated with the wall mounting recess 12, so that the strength of one side 31a (fixed end side) of the deformation member 31 is improved. Note that the deformable member 31 may be adhered to the inner side surface 14 of the wall mounting recess 12 .

The deformation member 31 has an uneven upper surface 31c. In this case, the entire upper surface 31c of the deformation member 31 may be formed in an uneven shape, or a part of the upper surface 31c may be formed in an uneven shape. An adhesive material 35 is adhered to the uneven upper surface 31c. Thereby, the contact surface (bonding surface) between the upper surface 31c of the deformation member 31 and the adhesive material 35 can be enlarged. Therefore, when the wall member 20 is removed from the wall mounting recess 12, it is possible to prevent the adhesive material 35 from peeling off from the deformable material 31. FIG. Further, when the wall member 20 is inserted into the wall mounting recess 12 and the adhesive material 35 is pressed against the wall member 20 , the adhesive material 35 can be prevented from sliding in the horizontal direction with respect to the deformable member 31 . This can prevent the adhesive material 35 from peeling off from the deformable material 31 . In the example shown in FIG. 3, the upper surface 31c of the deformable member 31 is formed in a curved shape. good.

The adhesive material 35 is provided on the upper surface 31 c 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 smaller 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 determined through experiments and simulations based on the depth dimension of the wall mounting recess 12, the specifications of the wall member 20, the strength and elastic deformation amount of the deformable material 31, and the like. set by Thereby, the pressing force between the wall member 20 and the adhesive material 35 can be adjusted by the elastic deformation of the deformable material 31 . Therefore, the adhesive force of the adhesive material 35 can be made to satisfy a balance between stopping water and removing the wall member 20 . As a result, since the adhesive material 35 of the seal member 30 is excellent in releasability from the wall member 20, the workability of attaching and detaching the wall member 20 can be improved.

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 wall member mounting structure 1 according to the present embodiment has the configuration described above. Next, the operation 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 elastically deformed downward by being pressed by the wall member 20 , and can absorb the 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 adhesive material 35 provided on the upper surface 31c of the deformation member 31 can effectively seal the space between the wall member 20 and the wall mounting recess 12 . In this case, the amount of deformation of the deformable member 31 changes even in a portion where the gap between the wall member 20 and the wall mounting recess 12 is large, so that the sealing performance can be maintained firmly. Additionally, a seal member 30 extends from the inner surface 14 of the wall-mounting recess 12 . Therefore, the same sealing member 30 can be used for various wall-mounting recesses 12 having different depth dimensions, simply by adjusting the mounting height of the sealing member 30 . Therefore, since the thickness dimension of the sealing member 30 can be reduced, it is excellent in stability and ensures watertightness even if the gap between the wall member 20 and the wall mounting recess 12 changes. can be done.

One side 31a of the deformable material 31 is a fixed end and the other side 31b is a free end. (H1<H2). In this case, the elastic deformation of the deformation member 31 can adjust the pressing force between the wall member 20 and the adhesive member 35 . As a result, the adhesive force of the adhesive material 35 can satisfy a balance between stopping water and removing the wall member 20 . Therefore, since the adhesive material 35 of the seal member 30 is excellent in releasability from the wall member 20, the workability of attaching and detaching the wall member 20 can be improved.

Moreover, the upper surface 31c 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 31c of the deformation member 31 can suppress this horizontal pressing force, the adhesive member 35 can be suppressed from sliding on the deformation member 31 in the horizontal direction. 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 Regulate sinking. 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.

Next, FIGS. 4 and 5 show a wall member mounting structure according to a second embodiment of the present invention. A feature of the second embodiment resides in that a wall receiving member 50 having a seal member 60 is provided in the wall mounting recess 12 . In addition, in the second embodiment, the same reference numerals are given to the same constituent elements as in the above-described first embodiment, and the description thereof will be omitted.
FIG. 4 is a cross-sectional view similar to FIG. 2 showing a state in which the wall member is inserted into the wall receiving member used in the wall member mounting structure according to the second embodiment.
FIG. 5 is a cross-sectional view similar to FIG. 3 showing the state when inserting the wall member into the wall receiving member.

The wall receiving member 50 is provided within the wall mounting recess 12 . The wall receiving member 50 is continuously provided along the length direction of the wall mounting recess 12 . The wall receiving member 50 is formed in a concave shape with an upper opening, and the wall member 20 is inserted therein.
