Description

  Aspects of the present invention generally relate to a bathroom wall member mounting structure.

  Bathrooms with washroom floors and bathroom wall members are known. In addition, in order to define the arrangement position of the bathroom wall member, a wall mounting recess is provided on the upper surface of the washroom floor, and the bathroom wall member mounting structure in which the wall receiving member and the bathroom wall member are inserted and arranged in the wall mounting recess is also known. (For example, Patent Document 1). The wall receiving member is formed in a concave shape, and the bathroom wall member is placed on the wall mounting recess with the lower end inserted into the wall receiving member.

  In such a bathroom wall member mounting structure, in order to prevent water from passing through the wall-mounted recess and leaking outside the bathroom, that is, to the building frame side, the wall-mounted recess, the bathroom wall member, and the wall receiving member A caulking material such as silicone is applied to the enclosed space.

  However, even if the caulking material is applied, the caulking material may be peeled off from the wall mounting recess or the bathroom wall member due to the passage of time or an unexpected external force applied to the bathroom wall member. As a result, water may leak out of the bathroom through the wall-mounted recess. Accordingly, the applicant has studied the caulking material and how to hit the caulking material having high adhesion to the wall mounting recess, bathroom wall member, and wall receiving member (hard to peel off), but there is still room for study. .

Japanese Patent Laying-Open No. 2015-166540

  The present invention has been made based on recognition of such problems, and an object thereof is to provide a bathroom wall member mounting structure capable of suppressing the peeling of the caulking material due to the passage of time or external force applied to the bathroom wall member. To do.

  According to a first aspect of the present invention, there is provided a washroom floor having a floor surface and a wall-mounted recess provided along an outer edge of the floor surface, a concave wall receiving member provided in the wall-mounted recess, and the floor The wall-mounted recess and the bathroom wall member placed on the wall-receiving member with the lower end inserted into the wall-receiving member, and the wall-mounted recess, An inner bottom surface recessed below the floor surface, a first inner surface provided on one end side of the inner bottom surface on the floor surface side and extending upward from the inner bottom surface toward the floor surface, and the inner bottom surface A second inner side surface extending upward from the inner bottom surface, and the wall receiving member includes a bottom surface portion provided on the inner bottom surface, and the floor of the bottom surface portion. A first side surface portion extending upward from one end side of the surface side, and a second side surface portion extending upward from the other end side of the bottom surface portion. An upper end of the first side surface portion is located below the floor surface, and a space that allows application of a caulking material together with the first inner side surface and the surface of the bathroom wall member is provided. Adhesiveness to the caulking material of the upper end of the side part is lower than adhesiveness to the caulking material of the first inner side surface and adhesiveness of the surface of the bathroom wall member to the caulking material, and from the floor surface. The bathroom wall member mounting structure is characterized in that, in the width direction toward the bathroom wall member, a center portion of the upper end of the first side surface portion is higher than both end portions of the upper end of the first side surface portion. .

  According to the mounting structure of the bathroom wall member, the upper end of the first side surface portion of the wall receiving member to which the caulking material is applied is deliberately made of the caulking material than the first inner side surface of the wall mounting recess and the surface of the bathroom wall member. While having low adhesiveness, the center of the upper end is made higher than both ends. As a result, the caulking material applied in the space is more difficult to adhere to the first inner side surface of the wall mounting recess and the upper end of the first side surface portion of the wall receiving member than the surface of the bathroom wall member, and is applied to the space. The thickness of the central portion of the caulking material can be made thinner than both end portions. As a result, when the interval between the first inner surface and the surface of the bathroom wall member changes due to the passage of time or external force, the central portion in the width direction of the caulking material is more than the both end portions in the width direction of the caulking material. Can also be easily stretched. This suppresses large stress from being applied to the contact interface between the caulking material and the first inner surface, and the contact interface between the coking material and the surface of the bathroom wall member, and the caulking from the surface of the first inner surface and the bathroom wall member. It can suppress that material peels. From the above, it is possible to provide a bathroom wall member mounting structure capable of suppressing the peeling of the caulking material due to the passage of time or external force applied to the bathroom wall member.

  In a second aspect based on the first aspect, the distance between the floor surface and the surface of the bathroom wall member is greater than the depth from the floor surface to the central portion of the upper end of the first side surface portion. The bathroom wall member mounting structure is characterized in that it is also wide.

  According to this bathroom wall member mounting structure, the thickness of the central portion in the width direction of the caulking material applied in the space can be made thinner than the length in the width direction of the caulking material applied in the space. The stretchability of the central portion in the width direction of the caulking material can be further improved. Therefore, peeling of the caulking material can be more reliably suppressed.

  A third aspect of the invention is the bathroom wall according to the first or second aspect of the invention, wherein the central portion of the upper end of the first side surface portion has an arch shape that gradually decreases toward the both end portions. It is the attachment structure of a member.

  According to this bathroom wall member mounting structure, it is possible to prevent the caulking material applied in the space from being suddenly thinned at the central portion in the width direction. For example, when the interval between the first inner surface and the surface of the bathroom wall member becomes wide due to the passage of time or external force, stress is locally applied to the central portion in the width direction of the caulking material, and the caulking material It can suppress that a crack etc. arise in the center part in the width direction.

  According to a fourth invention, in any one of the first to third inventions, the first side surface portion includes a main body portion and a tip portion provided at an upper end of the main body portion, The bathroom wall is characterized in that the upper end of the side part is provided at the tip part, and the adhesiveness of the main body part and the bottom part to the caulking material is higher than the adhesiveness of the tip part to the caulking material. It is the attachment structure of a member.

  According to this bathroom wall member mounting structure, the adhesiveness of the main body portion and the bottom surface portion to the caulking material is increased while lowering the adhesiveness to the caulking material at the upper end of the first side surface portion of the wall receiving member. Thus, for example, when a caulking material is applied between the wall receiving member and the wall mounting recess, or when a caulking material is applied between the wall receiving member and the bathroom wall member, the caulking material is appropriately received. It can adhere | attach on a member and can improve the water stop between each member more.

  ADVANTAGE OF THE INVENTION According to the aspect of this invention, the attachment structure of the bathroom wall member which can suppress peeling of the caulking material by progress of time, the external force added to a bathroom wall member, etc. is provided.

Drawing 1 is a perspective view showing typically a bathroom unit provided with the attachment structure of the bathroom wall member concerning an embodiment.
As shown in FIG. 1, the bathroom unit 10 includes a washing floor 100, a bathtub 200, and a bathroom wall member 300.
Support legs 260 are provided in the vicinity of the four corners on the bottom rear surface of the bathtub 200, and the bathtub 200 is installed on a bathroom installation surface (for example, a building floor) S via the support legs 260. The support leg 260 has a structure whose height can be adjusted by rotating the bolt portion.

  The washing floor 100 is formed in a shallow vessel shape (bread shape) whose peripheral edge is bent upward, and has a waterproof property that prevents water from leaking outside the bathroom. And it is installed on the bathroom installation surface S via the support leg 111 which has a structure which can adjust height by rotating a volt | bolt part. In the present specification, the term “water” includes not only cold water but also warm hot water.

  The bathroom wall member 300 constitutes four surfaces of the bathroom unit 10 and includes first to sixth bathroom wall members 310 to 360 as bathroom wall members of the present embodiment. The bathroom wall member 300 forms a standing wall surface of the bathroom unit 10. Between adjacent bathroom wall members, a connecting member 305 that connects adjacent bathroom wall members is erected on the outer peripheral portion 100 a of the washing floor 100.

  The 1st bathroom wall member 310 is arrange | positioned on the opposite side to the bathtub 200 of the washing floor 100, and the 2 bathroom wall members are connected by the connection member 305 which is not shown in figure. The second bathroom wall member 320 and the third bathroom wall member 330 are orthogonal to the first bathroom wall member 310 and are disposed to face each other. The 4th-6th bathroom wall member 340-360 is arrange | positioned among the edges of the bathtub 200 on the edge of 3 sides except the washing-room floor 100 side. A small panel 370 is provided below the fourth bathroom wall member 340 and the fifth bathroom wall member 350 to connect between the bathtub 200 and the second bathroom wall member 320 and the third bathroom wall member 330. ing. The small panel 370 is one of the bathroom wall members 300 of the present embodiment.

  Note that the configuration of the bathroom wall member 300 in the present embodiment is not limited to this, and is a configuration in which one panel is divided into a plurality of panels or a configuration in which a plurality of adjacent panels are integrated. May be.

  In the bathroom unit 10 illustrated in FIG. 1, the third bathroom wall member 330 is provided with a door DR via a door mounting frame (not shown). In the present embodiment, the bathroom wall member 330 including the door mounting frame is also included in the bathroom wall member 300. That is, in this embodiment, the bathroom wall member 300 includes a wall panel and a door mounting frame.

  At the boundary between the bathtub 200 and the washing floor 100, a bath apron 290 that covers the side surface of the bathtub 200 on the washing floor 100 side is provided. Note that depending on the structure of the bathtub 200, there may be a case where the bath apron 290 may not be provided.

FIG. 2 is an exploded perspective view schematically showing the washing place floor according to the present embodiment.
As shown in FIG. 2, the washroom floor 100 includes a floor base 110 and a floor body 120.

  The floor base material 110 includes support legs 111, a support frame 113, and a receiving plate 115. The support frame 113 includes, for example, four first frames 113a whose longitudinal direction is arranged in the first direction and four fourth frames arranged in the second direction whose longitudinal direction is orthogonal to the first direction. 2 frames 113b. The support legs 111 are provided at the four corners of the lower surface of the support frame 113. The support leg 111 has a bolt part, and has a structure whose height can be adjusted by rotation of the bolt part.

  The floor base material 110 receives a load applied to the upper surface of the washing floor 100 in a limited space such as a bathroom and holds the position. Therefore, the floor base 110 needs to have sufficient strength. For example, the floor substrate 110 has a strength higher than that of a thermoplastic foam resin. Therefore, as an example of obtaining this sufficient strength, steel material is used for the floor base material 110 in the present embodiment.

  The floor base material 110 is placed on an installation surface such as a bathroom (for example, the floor of a building), and the height is appropriately adjusted by the rotation of the bolt portion of the support leg 111. Thereby, the horizontal surface of the washing floor 100 is ensured. The support legs 111 and the support frame 113 support the receiving plate 115 from below. In other words, the receiving plate 115 is placed on the support leg 111 and the support frame 113. The receiving plate 115 is fixed to the support frame 113 by a fastening member such as a screw.

  The floor main body 120 includes a floor surface material 130, a cushion material 140, and a surface material 150. The upper surface of the receiving plate 115 serves as a vertical reference position, that is, a horizontal reference surface, of each member included in the washing floor 100. The receiving plate 115 supports the floor material 130 from below and receives a load from a member placed on the receiving plate 115. Therefore, the receiving plate 115 is preferably a flat plate material having relatively high strength and rigidity. As an example, for example, a steel deck plate or a sandwich panel may be used. The strength of the floor base material 110 is higher than the strength of the floor surface material 130 formed of a thermoplastic foam resin described later.

  The floor base material 110 will be further described. The floor base material 110 is formed of a material having higher rigidity than that of the floor main body 120. The upper surface of the floor substrate 110 (the upper surface of the receiving plate 115) has a flat placement surface that supports the floor body 120. For example, when a deck plate is used as the receiving plate 115, the upper surface of the portion formed in a corrugated shape has a flat mounting surface.

A floor material 130 is placed on the floor substrate 110. The floor surface material 130 is formed of a thermoplastic foam resin and is supported from below by the floor base material 110. Examples of the thermoplastic foamed resin include foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane. In this embodiment, foamed polypropylene is used as an example. Since the thermoplastic foamed resin is recyclable, the use of this makes it possible to reduce the CO ₂ emission accompanying the production and disposal of the floor covering 130 and provide an environmentally friendly product. In addition, since the mold used for foam molding can be manufactured at a lower cost than molds obtained by other molding methods, the manufacturing cost of the washroom floor can be kept low.

  A surface material 150 is provided on the floor material 130 via a cushion material 140. The cushioning material 140 and the surface material 150 are used to improve the sensory performance such as the appearance design and feeling of use of the floor surface of the washing floor 100 and the functions that are inevitably required for the washing floor 100 such as waterproofness. It has been.

  That is, the cushion material 140 obtains the softness of the floor surface given to the user. As a material of the cushion material 140, for example, a soft material such as foamed polyurethane is used. By changing the hardness (softness) of the cushion material 140, the specification of the hardness (softness) of the floor surface can be changed.

  The surface material 150 covers the upper surface of the floor surface material 130 and forms the surface of the washing floor 100. The surface material 150 has flexibility. As the material of the surface material 150, a soft sheet material having waterproofness and flexibility is used. The material of the surface material 150 can be expanded and contracted as the floor surface material 130 expands and contracts as will be described later. In order to improve the design and drainage of the surface of the washing floor 100, the surface material 150 can be subjected to uneven processing or a pattern.

Fig.3 (a) and FIG.3 (b) are sectional drawings which represent typically the attachment structure of the bathroom wall member which concerns on embodiment.
FIG. 3A and FIG. 3B are cross-sectional views schematically showing the cut surface AA shown in FIG.
As shown in FIG. 3A and FIG. 3B, the wash floor 100 has a floor surface 150 a and a wall-mounted recess 160. The floor surface 150a is exposed in the space surrounded by each bathroom wall member 300 and is a part that is actually used as a washing place by the user. The floor surface 150a is, for example, the upper surface of the surface material 150. The wall-mounted recess 160 is provided along the outer edge of the floor surface 150a. The wall-mounted recess 160 is provided, for example, so as to extend along the entire three sides that are not adjacent to the bathtub 200 among the four sides (outer edges) of the floor surface 150a. The wall mounting recess 160 is provided in the floor surface material 130, for example.

  The wall-mounted recess 160 has a first inner side surface 161, a second inner side surface 162, and an inner bottom surface 164. The inner bottom surface 164 is recessed below the floor surface 150a. The first inner surface 161 is provided on one end side of the inner bottom surface 164 on the floor surface 150a side. The first inner surface 161 extends upward from the inner bottom surface 164 toward the floor surface 150a. In other words, the first inner side surface 161 connects one end of the inner bottom surface 164 and one end of the floor surface 150a. The first inner surface 161 is formed by, for example, the side surface of the floor material 130 and the side surface of the surface material 150. The second inner surface 162 is provided on the other end side of the inner bottom surface 164. The second inner side surface 162 extends upward from the other end of the inner bottom surface 164.

  The bathroom unit 10 further includes a wall receiving member 400. The wall receiving member 400 is provided in the wall mounting recess 160. The wall receiving member 400 is concave. Similarly to the wall mounting recess 160, the wall receiving member 400 extends along the outer edge of the floor surface 150a. The wall receiving member 400 is a long member having a substantially U-shaped cross section. The wall receiving member 400 receives the lower ends of one or a plurality of adjacent bathroom wall members 300 in the wall mounting recess 160.

  The wall receiving member 400 includes a first side surface portion 410, a second side surface portion 420, and a bottom surface portion 440. The bottom surface portion 440 is provided on the inner bottom surface 164. The first side surface portion 410 extends upward from one end side of the bottom surface portion 440 on the floor surface 150a side. The second side surface portion 420 extends upward from the other end side of the bottom surface portion 440.

  The bathroom wall member 300 has a surface 300a facing the floor surface 150a. The bathroom wall member 300 is placed on the wall mounting recess 160 and the wall receiving member 400 with the lower end 300 b inserted into the concave wall receiving member 400.

  As shown in FIG. 3A, the wall receiving member 400 is provided in the wall mounting recess 160 with the first side surface portion 410 being brought closer to the first inner surface 161 side of the wall mounting recess 160. For example, the first side surface portion 410 contacts the first inner surface 161. And the bathroom wall member 300 is mounted on the wall receiving member 400 in the state which brought the surface 300a close to the 1st side surface part 410 side. The surface 300a contacts the first side surface portion 410, for example. Thereby, the wall receiving member 400 sets the distance between the floor surface 150a and the surface 300a to the thickness of the first side surface portion 410. The wall receiving member 400 makes it easy to determine the position of the bathroom wall member 300 with respect to the floor surface 150a, for example. The wall receiving member 400 may be called a guide piece, for example.

  For example, a packing 450 is provided between the bathroom wall member 300 and the wall receiving member 400. The packing 450 is made of an elastic material such as rubber, and fills a gap between the bathroom wall member 300 and the wall receiving member 400 to improve water tightness.

  An upper end 410a of the first side surface portion 410 is located below the floor surface 150a of the washing floor 100. Accordingly, the upper end 410a of the first side surface portion 410 provides a space SP that enables the application of the caulking material 460 together with the first inner side surface 161 and the surface 300a of the bathroom wall member 300.

  The caulking material 460 is applied to fill the space SP, for example. That is, the caulking material 460 is applied from the upper end 410a of the first side surface portion 410 to the height of the floor surface 150a. Thereby, the caulking material 460 suppresses that water leaks from the floor surface 150a to the back side of the bathroom wall member 300. In other words, the caulking material 460 prevents water from leaking from the indoor side of the bathroom unit 10 to the building frame side. For the caulking material 460, for example, silicone is used.

  The adhesiveness of the upper end 410a of the first side surface portion 410 to the caulking material 460 is lower than the adhesiveness of the first inner surface 161 to the caulking material 460 and the adhesiveness of the surface 300a of the bathroom wall member 300 to the caulking material 460. The upper end 410a does not substantially adhere to the caulking material 460, for example. The caulking material 460, for example, adheres to the first inner surface 161 and the surface 300a to ensure watertightness, and does not adhere to the upper end 410a.

  However, the adhesiveness of the upper end 410a to the caulking material 460 may be lower than the adhesiveness of the first inner surface 161 to the caulking material 460 and the adhesiveness of the surface 300a to the caulking material 460. The caulking material 460 may be partially bonded to the upper end 410a or may be bonded to the upper end 410a with an adhesive force lower than that of the first inner surface 161 or the surface 300a.

  The first side surface part 410 has a main body part 411 and a tip part 412. The tip portion 412 is provided at the upper end of the main body portion 411. An upper end 410 a of the first side surface portion 410 is provided at the distal end portion 412. In other words, the upper end 410 a of the first side surface portion 410 is the upper end of the distal end portion 412. The tip portion 412 is provided at the upper end of the main body portion 411 by, for example, two-color molding.

  The adhesiveness of the main body portion 411 and the bottom surface portion 440 to the caulking material 460 is higher than the adhesiveness of the tip portion 412 to the caulking material 460. In this example, the main body portion 411 is formed integrally with the bottom surface portion 440. The bottom surface portion 440 is also formed integrally with the second side surface portion 420. Therefore, the material of the main body portion 411 and the second side surface portion 420 is substantially the same as the material of the bottom surface portion 440.

  For example, when a material such as silicone (for example, organopolysiloxane) or modified silicone (for example, polyether having a silyl group at the end) is used for the caulking material 460, the tip 412 (upper end 410a) is made of polyethylene. Or polypropylene is used, and vinyl chloride or the like is used for the main body portion 411 and the bottom surface portion 440. Thereby, as described above, the adhesiveness of the upper end 410a of the first side surface portion 410 to the caulking material 460 is greater than the adhesiveness of the first inner side surface 161 to the caulking material 460 and the adhesiveness of the surface 300a to the caulking material 460. While being able to make low, the adhesiveness with respect to the caulking material 460 of the main-body part 411 and the bottom face part 440 can be made higher than the adhesiveness with respect to the caulking material 460 of the front-end | tip part 412.

  The main body 411 and the second side surface 420 may be attached to the bottom surface portion 440 after being formed separately from the bottom surface portion 440, for example. The material of the main body portion 411 and the second side surface portion 420 may be different from the material of the bottom surface portion 440.

  The distal end portion 412 is connected and fixed to the upper end of the main body portion 411 by engaging with each other. More specifically, the distal end portion 412 has an engaging portion 412 a that engages with an engaged portion 411 a provided at the upper end of the main body portion 411. The tip portion 412 is formed by, for example, two-color molding, and is provided at the upper end of the main body portion 411 by the engagement of the engaged portion 411a and the engaging portion 412a. The engaging portion 412a engages with the engaged portion 411a in, for example, the vertical direction and the direction perpendicular to the surface 300a (the left-right direction on the paper surface in FIG. 3).

  When the above-described materials are used for the main body part 411, the front end part 412, and the caulking material 460, the adhesiveness between the main body part 411 and the front end part 412 may be lowered. Accordingly, the engaged portion 411 a and the engaging portion 412 a are provided, and the tip portion 412 is engaged with the main body portion 411. Thereby, it can suppress that the front-end | tip part 412 remove | deviates from the main-body part 411. FIG.

FIG. 4 is a partial sectional view schematically showing an enlarged part of the wall receiving member.
As shown in FIG. 4, in the width direction from the floor surface 150 a toward the bathroom wall member 300, the center portion CP of the upper end 410 a of the first side surface portion 410 is at both ends EP 1 and EP 2 of the upper end 410 a of the first side surface portion 410. Higher than. In other words, the width direction from the floor surface 150a toward the bathroom wall member 300 is a direction perpendicular to the surface 300a.

  The interval PT between the floor surface 150a and the surface 300a of the bathroom wall member 300 is wider than the depth DN from the floor surface 150a to the central portion CP of the upper end 410a of the first side surface portion 410. In other words, the horizontal distance from the upper end of the first inner side surface 161 to the surface 300a is longer than the vertical distance from the upper end of the first inner side surface 161 to the central portion CP of the upper end 410a.

  The central portion CP of the upper end 410a of the first side surface portion 410 has an arch shape that gradually decreases toward both end portions EP1 and EP2. In other words, the central portion CP is an upwardly convex curved surface. In this example, the tip portion 412 is formed in an arch shape. The shape of the central portion CP is not limited to the arch shape, and may be any shape that is higher than both end portions EP1 and EP2. The central portion CP may be, for example, a protrusion having a triangular cross section or a quadrangular cross section.

  As described above, according to the mounting structure of the bathroom wall member 300 according to the present embodiment, the upper end 410a of the first side surface portion 410 of the wall receiving member 400 to which the caulking material 460 is applied is connected to the wall mounting recess 160. The caulking material 460 has a lower adhesiveness than the first inner surface 161 and the surface 300a of the bathroom wall member 300, and the central portion CP of the upper end 410a is higher than the end portions EP1 and EP2. As a result, the caulking material 460 applied in the space SP adheres to the upper end 410a of the first side surface 410 of the wall receiving member 400 rather than the first inner surface 161 of the wall mounting recess 160 and the surface 300a of the bathroom wall member 300. While making it difficult, the thickness of the central part in the width direction of the caulking material 46 applied in the space SP can be made thinner than both end parts in the width direction. As a result, when the interval PT between the first inner surface 161 and the surface 300a of the bathroom wall member 300 changes due to the passage of time or external force, the central portion in the width direction of the caulking material 460 is replaced with the caulking material 460. It can be made easier to expand and contract than both end portions in the width direction.

  For example, when a thermoplastic foam resin or the like is used for the flooring material 130, as shown in FIG. 3B due to thermal expansion or contraction of the flooring material 130, the first inner side surface 161 and the surface 300a The interval PT may be unintentionally widened. In such a case, the central portion of the caulking material 460 can be more easily expanded and contracted than both end portions of the caulking material 460.

  Thereby, it is suppressed that a big stress is added to the contact interface of the caulking material 460 and the 1st inner surface 161, and the contact interface of the caulking material 460 and the surface 300a of the bathroom wall member 300, The 1st inner surface 161 and the bathroom It can suppress that the caulking material 460 peels from the surface 300a of the wall member 300. FIG. From the above, it is possible to provide a mounting structure for the bathroom wall member 300 that can suppress the peeling of the caulking material 460 due to the passage of time or an external force applied to the bathroom wall member 300.

  Moreover, in the attachment structure of the bathroom wall member 300 according to the present embodiment, the interval PT between the floor surface 150a and the surface 300a of the bathroom wall member 300 is set at the center of the upper end 410a of the first side surface portion 410 from the floor surface 150a. It is wider than the depth DN up to the CP. Accordingly, the thickness of the central portion that can be placed in the width direction of the caulking material 460 applied in the space SP can be made thinner than the length in the width direction of the caulking material 460 applied in the space SP. The stretchability of the central portion in the width direction of 460 can be further improved. Therefore, peeling of the caulking material 460 can be more reliably suppressed.

  Moreover, in the attachment structure of the bathroom wall member 300 according to the present embodiment, the center portion CP of the upper end 410a of the first side surface portion 410 has an arch shape that gradually decreases toward both end portions EP1 and EP2. Thereby, it can suppress that the caulking material 460 apply | coated in space SP becomes thin thinly in the center part in the width direction. For example, when the interval PT between the first inner surface 161 and the surface 300a of the bathroom wall member 300 becomes wide due to the passage of time or external force, stress is locally applied to the central portion in the width direction of the caulking material 460. In addition, it is possible to suppress the occurrence of cracks or the like in the central portion of the caulking material 460 in the width direction. For example, when the central portion CP is a protrusion having a substantially triangular cross section or a substantially rectangular cross section, when the caulking material 460 extends, the corner portion of the central portion CP hinders displacement of the elongation of the caulking material 460, and There is a possibility that stress is locally applied at the corners of the portion CP. By making the central portion CP into an arch shape without corners, it is possible to suppress the cracking of the caulking material 460 accompanying such stress concentration.

  Moreover, in the attachment structure of the bathroom wall member 300 according to the present embodiment, the first side surface portion 410 has a main body portion 411 and a tip portion 412 provided at the upper end of the main body portion 411, and the first side surface portion. An upper end 410 a of 410 is provided at the tip portion 412, and the adhesiveness of the main body portion 411 and the bottom surface portion 440 to the caulking material 460 is higher than the adhesiveness of the tip portion 412 to the caulking material 460.

  As described above, the adhesiveness of the main body portion 411 and the bottom surface portion 440 to the caulking material 460 is increased while lowering the adhesiveness of the upper end 410a of the first side surface portion 410 of the wall receiving member 400 to the caulking material 460. Thereby, for example, when the caulking material 460 is applied between the wall receiving member 400 and the wall mounting recess 160, or when the caulking material 460 is applied between the wall receiving member 400 and the bathroom wall member 300, the caulking is performed. The material 460 can be appropriately bonded to the wall receiving member 400, and the water stoppage between these members can be further improved.

FIG. 5 is a cross-sectional view schematically showing a modification of the bathroom wall member mounting structure according to the embodiment. Note that components that are substantially the same in function and configuration as those in the above embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.
As shown in FIG. 5, in this example, the central portion of the upper end of the main body portion 411 is formed in an arch shape, and the distal end portion 412 is provided in a film shape on the upper end of the main body portion 411. The distal end portion 412 is provided on the upper end of the main body portion 411 by, for example, bonding.

  As described above, the distal end portion 412 may be provided on the upper end of the main body portion 411 by bonding. For example, when sufficient adhesiveness is obtained between the main body portion 411 and the distal end portion 412, the main body portion 411 and the distal end portion 412 do not necessarily have to be engaged. Thereby, the moldability of the wall receiving member 400 can be improved, for example. For example, the manufacturing cost of the wall receiving member 400 can be suppressed.

  The configuration of the wall receiving member 400 is not limited to the above, and the adhesiveness of the upper end 410a of the first side surface portion 410 to the caulking material 460, the adhesiveness of the first inner side surface 161 to the caulking material 460, and the bathroom wall member 300 are not limited. Any configuration that can lower the adhesion of the surface 300a to the caulking material 460 may be used.

  For example, the entire first side surface portion 410 may be formed of a material having low adhesion to the caulking material 460 and attached to the bottom surface portion 440. Alternatively, the entire wall receiving member 400 may be formed of a material having low adhesion to the caulking material 460.
