Description

  Aspects of the invention generally relate to bathroom structures.

  A bathroom structure using a foamed resin as a floor material constituting the floor surface of the bathroom is disclosed (Patent Document 1). In the bathroom structure disclosed in Patent Document 1, the waterproof pan is formed not by FRP (Fiber Reinforced Plastics), which is a general material for waterproof pans, but by a thermoplastic resin having a linear expansion coefficient higher than that of FRP. ing. In a waterproof pan formed of a thermoplastic resin, expansion and contraction of, for example, about several millimeters may occur due to seasonal temperature differences. Therefore, the width of the wall receiving groove on which the wall material (wall panel or door frame) is placed is wider than the thickness of the wall material so that the bathroom can be constructed more reliably even if the temperature difference occurs. Further, a silicone caulking material having adhesive force is filled in the silicone pocket between the wall material and the wall receiving groove. The linear expansion coefficient of the silicone caulking material is larger than that of the thermoplastic resin. Therefore, even if the waterproof pan constructed in summer shrinks in winter, the silicone caulking material will not break.

  However, if dirt is attached to the wall material or the wall receiving groove, the adhesive strength with the silicone caulking material is reduced, and the caulking material cannot exhibit its original adhesive strength. Therefore, for example, when a waterproof pan constructed in summer shrinks in winter, the interfacial peeling of the caulking material may occur between the wall material and the wall receiving groove depending on the temperature difference between seasons. When interfacial peeling of the caulking material occurs, the appearance deteriorates.

FIG. 1 is a schematic perspective view illustrating a bathroom unit including a bathroom structure according to an embodiment of the invention.

The bathroom unit shown in FIG. 1 includes a washing floor floor pan 100, a bathtub 200, and a wall material 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 washroom floor pan 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 out of 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 wall material 300 constitutes four surfaces of the bathroom unit, and includes first to sixth wall panels 310 to 360 as wall materials of the present embodiment. The wall material 300 forms a standing wall surface of the bathroom unit. Between the adjacent wall panels, a wall surface connecting member 305 that connects the adjacent wall panels is erected on the outer peripheral portion 100 a of the washing floor floor pan 100. The wall surface connecting member 305 is held by a wall surface fixing member described in detail later.

  The first wall panel 310 is disposed on the opposite side of the washing floor floor pan 100 from the bathtub 200, and is formed by connecting two wall panels by a wall connecting member 305 (not shown). The second wall panel 320 and the third wall panel 330 are disposed orthogonally to the first wall panel 310 and facing each other. The 4th-6th wall panels 340-360 are arrange | positioned among the edges of the bathtub 200 on the edge of 3 sides except the washing-room floor pan 100 side. Below the fourth wall panel 340 and the fifth wall panel 350, a small panel 370 that connects between the bathtub 200, the second wall panel 320, and the third wall panel 330 is provided. The small panel 370 is one of the wall materials 300 of the present embodiment.

Note that the configuration of the 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. Also good.
In the bathroom unit illustrated in FIG. 1, the third wall panel 330 is provided with a door DR via a door mounting frame (not shown). In this embodiment, the wall panel 330 including the door mounting frame is also included in the wall material 300. That is, in this embodiment, the wall material 300 includes a wall panel and a door mounting frame.

  A bath apron 290 is provided at the boundary between the bathtub 200 and the washing floor floor pan 100 to cover the side surface of the bathtub 200 on the washing floor floor pan 100 side. 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 a schematic exploded view showing the washing floor floor pan of the present embodiment.
The washing ground floor pan 100 according to the present embodiment includes a floor base 110 and a floor main 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 110 receives a load applied to the upper surface of the washing floor floor pan 100 in a limited space such as a bathroom, and maintains its 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 washroom floor pan 100 is secured. 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 pan 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. Moreover, since the mold used for foam molding can be manufactured at a lower cost than molds by other molding methods, the manufacturing cost of the washing floor floor pan can be kept low.

  Around the surface (surface) of the floor material 130 on the surface material 150 side, a wall receiving groove portion in which the wall material 300 is inserted and placed is provided. The wall receiving groove will be described in detail later.

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

  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 pan 100. The surface material 150 has flexibility. As the material of the surface material 150, a flexible soft sheet material having waterproofness 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 floor pan 100, the surface material 150 may be subjected to uneven processing or a pattern.

FIG. 3 is a schematic cross-sectional view illustrating the wall material restraining piece of the present embodiment.
FIG. 3A is a schematic cross-sectional view in which the vicinity of the wall receiving groove portion on which the wall material of the present embodiment is placed is enlarged. FIG.3 (b) is typical sectional drawing showing the wall material restraint piece of this embodiment.
FIGS. 3A and 3B are schematic cross-sectional views taken along the section AA shown in FIG.

  In the first wall panel 310 of this embodiment, a steel plate 313 is attached to the surface of a base material 311 such as a gypsum board for reinforcement. The steel plate 313 is attached to the surface of the base material 311, for example, inside the bathroom (washing station side), and is bent downward from the surface to the lower end 311 a side.

  A wall receiving groove portion 135 is provided on the outer edge portion 134 of the floor member 130. The wall receiving groove part 135 has a recessed part into which the wall member 300 is inserted, a standing wall as a waterproof wall, and the like. The wall receiving groove portion 135 has a concave shape in cross section, and forms a water stop structure at a connection portion with the bathroom floor surface. The lower part of the first wall panel 310 corresponding to the wall member 300 is inserted into the recess of the wall receiving groove part 135. That is, the lower end portion of the wall material 300 is stored in the wall receiving groove portion 135 provided around the floor surface material 130.

  The wall receiving groove part 135 has a width larger than the thickness of the lower end part of the wall material 300. In the present embodiment, the width D1 of the concave portion of the wall receiving groove portion 135 is larger than the thickness D2 of the lower end portion of the first wall panel 310 (the thickness obtained by combining the base material 311 and the steel plate 313). The bent portion 313 a of the steel plate 313 of the first wall panel 310 is placed on the bottom surface of the recess through the wall material restraining piece 170 provided in the wall receiving groove portion 135 of the floor surface material 130. An elastic body such as packing may be provided between the bent portion 313a of the first wall panel 310 and the wall material restraining piece 170, for example.

  In the state where the first wall panel 310 is erected, the first side portion 135a of the wall receiving groove 135 inside the bathroom and the first surface 300a of the wall member 300 inside the bathroom (first in FIG. 3A). A pocket PC that can be filled with the caulking material CK is formed between the first surface 310a) of the wall panel 310 and the wall panel 310. In the present embodiment, a caulking material CK for waterproofing is provided in the gap between the recess and the steel plate 313 of the first wall panel 310 in a state where the first wall panel 310 is erected. The caulking CK prevents water in the bathroom from flowing into the back side of the first wall panel 310. The caulking CK is, for example, silicone. In this case, the silicone bonds the first wall panel 310 and the first side portion 135 a inside the bathroom of the wall receiving groove portion 135.

  Here, as described above with reference to FIG. 2, the floor material 130 is formed of a thermoplastic foam resin. In general, foamed plastics are more likely to expand and contract under the influence of changes in ambient temperature (air temperature) than FRP (Fiber Reinforced Plastics) and the like. Therefore, as indicated by an arrow A1 illustrated in FIG. 3A, the floor material 130 according to the present embodiment easily expands and contracts due to a change in temperature such as a season. And the planar dimension of the floor covering 130 may change.

  On the other hand, the wall material 300 is fixed to the floor base material 110 via the wall surface connection member 305 and the wall surface fixing member 307 (see FIG. 8). Adjacent wall panels are connected to each other via a wall surface connecting member 305. Therefore, the change in the position of the wall member 300 due to the change in temperature is less than the expansion and contraction of the floor member 130 due to the change in temperature.

  For example, when the flooring material 130 constructed in summer shrinks in the winter, the reduced adhesive strength of the caulking material CK cannot withstand expansion and contraction of the flooring material 130 depending on the temperature difference between seasons, and the wall material 300 (FIG. 3 (a ) May cause interfacial delamination between the first wall panel 310) and the first side 135a of the wall receiving groove 135 inside the bathroom. When interfacial peeling occurs, the appearance deteriorates.

  In contrast, a wall material restraining piece 170 is provided in the wall receiving groove portion 135 of the floor surface material 130 of the present embodiment. For example, the wall material restraining piece 170 is bonded to at least one of the side surface and the bottom surface of the concave portion of the wall receiving groove portion 135. The material of the wall material restraining piece 170 includes, for example, resin or metal. The wall material restraining piece 170 restrains the relative position of the position of the wall material 300 with respect to the wall receiving groove 135 in the thickness direction (the direction of the arrow A1 shown in FIG. 3A). More specifically, the wall material restraining piece 170 has a first surface 300a inside the bathroom of the wall member 300 relative to the first side 135a inside the bathroom of the wall receiving groove 135 (in FIG. The first surface 310a) of one wall panel 310 is constrained. Further, the wall material restraining piece 170 has a second side 300b outside the bathroom of the wall member 300 with respect to the second side 135b outside the bathroom of the wall receiving groove 135 (the first wall panel in FIG. 3A). The surface 310b) of 310 is restrained.

  As illustrated in FIG. 3B, the wall material restraining piece 170 according to the present embodiment includes an inner restraining portion 171 and an outer restraining portion 172. The inner restraint portion 171 is provided inside the bathroom as viewed from the outer restraint portion 172 and causes the first surface 300 a of the wall member 300 to be stretched against the first side portion 135 a of the wall receiving groove portion 135. The outer restraint portion 172 is provided outside the bathroom as viewed from the inner restraint portion 171, and causes the second surface 300b of the wall member 300 to be stretched against the second side portion 135b of the wall receiving groove portion 135.

  A wall material clamping part 173 is provided between the inner restraint part 171 and the outer restraint part 172. The wall material sandwiching portion 173 restrains the first surface 300 a of the wall material 300 and the second surface 300 b of the wall material 300 to sandwich the wall material 300. That is, the wall member 300 is sandwiched between the inner restraint portion 171 and the outer restraint portion 172. The wall material restraining piece 170 has a structure in which an inner restraint portion 171, an outer restraint portion 172, and a wall material sandwiching portion 173 are integrated.

  The inner restraint portion 171 is provided with a guide portion 175. The guide part 175 is provided in the upper end part of the inner restraint part 171, and has the inclined surface which the bathroom outer side retreated below rather than the bathroom inner side. The guide part 175 guides the lower end part of the wall material 300 to the wall material clamping part 173. As shown in FIG. 3A, the upper surface of the inner restraint portion 171 (the upper surface of the guide portion 175) is provided below the surface of the washing place (in this embodiment, the upper surface of the surface material 150).

  According to the present embodiment, the relative position of the wall member 300 with respect to the wall receiving groove 135 is fixed by the wall member restraining piece 170. As a result, even if the floor surface material 130 formed of the thermoplastic resin contracts due to a change in the air temperature after the construction of the bathroom unit, the relative position in the thickness direction of the wall material 300 with respect to the wall receiving groove 135 is not limited by the wall material. It is fixed by the piece 170. For this reason, the width D3 of the pocket PC filled with the caulking material CK (the gap between the first side portion 135a of the wall receiving groove 135 and the first surface 300a of the wall material 300) D3 is hardly changed. Therefore, the width of the caulking material CK filled in the pocket PC hardly changes depending on the temperature change. Thereby, even if dirt adheres to the wall material 300 and the wall receiving groove 135 and the adhesive force with the caulking material CK is reduced, the caulking material CK has the interface with the floor surface material 130 and the wall material 300. Can be prevented from peeling at the interface. In addition, the appearance of the peripheral edge of the washing floor floor pan 100 can be well maintained over a long period of time.

  The wall material restraining piece 170 restrains the wall material 300 with respect to each of the first side portion 135a of the wall receiving groove portion 135 and the second side portion 135b facing the first side portion 135a. . As shown in FIG. 3A, the wall material restraining piece 170 has a wall at a position away from the first side portion 135 a of the wall receiving groove portion 135 and the second side portion 135 b of the wall receiving groove portion 135. The material 300 is restrained. Thereby, the pocket PC filled with the caulking material CK can be reliably formed and maintained in a predetermined dimension (width D3). Further, the second surface 300 b of the wall material 300 does not contact the second side portion 135 b of the wall receiving groove portion 135, and the wall material restraining piece 170 contacts the second side portion 135 b of the wall receiving groove portion 135. Further, as in the first wall panel 310, when the wall member 300 has a bent portion 313a at the lower end of the wall member 300 bent toward the second side portion 135b, the tip of the bent portion 313a is a wall receiving groove portion. When the second side portion 135b of the 135 is pressurized, the wall receiving groove portion 135 may be damaged. However, in this embodiment, the outer restraining portion 172 of the wall material restraining piece 170 is connected to the distal end of the bent portion 313a and the wall receiving groove portion 135. The second side portion 135b is protected from contact. Thereby, damage to the wall receiving groove portion 135 can be suppressed.

  As described above, the wall material restraining piece 170 has a structure in which the inner restraint portion 171, the outer restraint portion 172, and the wall material sandwiching portion 173 are integrated. Therefore, for example, an operator or the like can handle the wall material restraining piece 170 more easily. Therefore, for example, an operator or the like can easily attach the wall material restraining piece 170 by the wall receiving groove portion 135. Thereby, it can suppress that the effort of manufacture of the flooring material 130 increases.

  For example, when an operator or the like tilts the wall material 300 obliquely and inserts the lower end portion of the wall material 300 into the wall receiving groove 135 from the inside of the bathroom, the lower end portion of the wall material 300 is the inner restraint portion of the wall material restraint piece 170. The guide member 175 guides the wall material sandwiching portion 173 without staying on the upper surface of 171. Thereby, the lower end part of the wall material 300 inserted into the wall receiving groove part 135 from above can be more reliably accommodated in the wall material clamping part 173. Moreover, the relative position of the wall material 300 with respect to the wall receiving groove part 135 can be restrained.

As described above, the upper surface of the inner restraint portion 171 is provided below the surface of the washing place. Thereby, the wall material restraining piece 170 is provided in the wall receiving groove part 135, and the pocket PC filled with the caulking material CK can be formed.
Note that when the wall material restraining piece 170 is provided in the wall receiving groove portion 135, the height of the outer restraining portion 172 is higher than the height of the inner restraining portion 171. Thereby, an operator etc. can perform the operation | work which inserts the lower end part of the wall material 300 into the wall receiving groove part 135 from the top more easily.

  The installation form of the wall material restraining piece 170a shown in FIGS. 4A and 4B is the same as that of the wall material restraining piece 170 described above with reference to FIGS. 3A and 3B. The material of the wall material restraining piece 170a includes, for example, resin or metal. The wall material restraining piece 170a restrains the relative position in the thickness direction (the direction of arrow A1 shown in FIG. 4A) of the position of the wall material 300 with respect to the wall receiving groove 135.

  As shown in FIG. 4B, the wall material restraining piece 170a of the present embodiment includes an inner restraining portion 171a and an outer restraining portion 172a. The inner restraint portion 171a is provided inside the bathroom as viewed from the outer restraint portion 172a, and causes the first surface 300a of the wall member 300 to be stretched against the first side portion 135a of the wall receiving groove portion 135. The outer restraint portion 172a is provided outside the bathroom as viewed from the inner restraint portion 171a, and pushes the second surface 300b of the wall material 300 against the second side portion 135b of the wall receiving groove portion 135.

  A wall material sandwiching portion 173a is provided between the inner restraint portion 171a and the outer restraint portion 172a. The wall material clamping unit 173a holds the wall material 300 by restraining the first surface 300a of the wall material 300 and the second surface 300b of the wall material 300. That is, the wall member 300 is sandwiched between the inner restraint portion 171a and the outer restraint portion 172a. The wall material restraining piece 170a has a structure in which an inner restraint portion 171a, an outer restraint portion 172a, and a wall material sandwiching portion 173a are integrated.

  A guide portion 175a is provided in the inner restraint portion 171a.
