Description

  An aspect of the present invention relates to a bathroom structure using a foamed resin as a floor material of a bathroom.

  A bathroom structure using foamed plastic as a floor material constituting the floor surface of the bathroom is disclosed (Patent Document 1). In the bathroom structure described in Patent Document 1, a wall mounting portion for standing a wall panel is provided on the peripheral portion of the floor material. The wall mounting portion is made of a low foam plastic. 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, in the bathroom structure described in Patent Document 1, when the floor material made of foamed plastic or the wall mounting portion expands and contracts due to a change in air temperature, the position of the wall panel may change. Then, the assemblability including the positioning operation of the wall panel may be deteriorated.

  In addition, there is a bathroom structure in which a wall panel constituting a wall of a washing place is erected on the edge of a waterproof pan formed of a thermoplastic resin (Patent Document 2). In the bathroom structure described in Patent Document 2, the side end portion of the wall panel is supported by a pillar member fixed to a plate-like frame. However, when the waterproof pan expands and contracts due to a change in temperature, the position of the wall panel changes, and the bathroom may be distorted.

Japanese Patent Application Laid-Open No. 11-343650 JP 2008-25122 A

  The present invention has been made on the basis of recognition of such a problem, and even when the plane dimension changes due to expansion and contraction, the influence on the positioning of the wall panel can be suppressed, or the assemblability can be maintained. The purpose is to provide a bathroom structure.

  A first aspect of the present invention is a floor surface material formed of a thermoplastic foam resin and a material that expands and contracts in accordance with the expansion and contraction of the floor surface material, and is provided on the floor surface material and provided on the surface of a washing place A floor body having a surface material, and a support leg that is formed of a material having rigidity higher than the rigidity of the floor body, and whose upper surface is a flat mounting surface that supports the floor body, the height of which can be adjusted. Is provided on the lower surface, a wall surface material that is provided around the floor main body and forms a standing wall surface of a bathroom, and a wall surface connecting member that is provided around the floor base material and supports the wall surface material A wall fixing member that holds a wall receiving groove portion around which the wall surface material is placed, and the wall receiving groove portion is larger than a thickness of a lower end portion of the wall surface material. Even if the floor material expands and contracts, the wall surface connecting member Lifting by said wall material is a bathroom structure characterized in that it has a width that fits the wall receiving groove portion.

  According to this bathroom structure, the floor surface material formed of the thermoplastic foamed resin has a characteristic that the size (planar dimension) varies depending on the season because it expands and contracts due to a change in temperature. On the other hand, the wall surface fixing member is fixed to the floor base material and holds the wall surface connecting member that supports the wall surface material. Therefore, the wall surface material is not affected by a change in the size of the floor surface material, and is installed at a regular position. In addition, the wall receiving groove provided in the peripheral edge of the floor main body (outer edge of the floor material) is the lower end of the wall material supported at the normal position by the wall connecting member even when the floor material expands and contracts. Have an acceptable width. Therefore, even if a common flooring material is used in different seasons, the size of the assembled bathroom does not change, and the bathroom can be assembled more accurately. In addition, since the mold used for foam molding can be manufactured at a lower cost than molds made by other molding methods, the production cost of the flooring material can be kept low, and the bathroom with resin flooring is less expensive than before. Will be available.

  The second invention is a bathroom structure characterized in that, in the first invention, the wall surface material and a side portion of the wall receiving groove portion on the washing area side are bonded with silicone.

  According to this bathroom structure, the amount of change in the width of the gap between the inner surface of the wall surface material and the inner side of the recess of the wall receiving groove can be further reduced. That is, when the temperature changes, the amount of change in the size of the floor base material is smaller than the amount of change in the size of the floor surface material. The silicone is filled and bonded between the lower end portion of the wall surface material fixed to the floor base material whose amount of change is smaller than that of the floor surface material and the wall receiving groove portion. The width of silicone is unlikely to change even when temperature changes occur. Therefore, even if the flooring material expands and contracts greatly after construction, the width of the gap between the inner wall surface of the wall material and the inner side wall portion of the concave portion of the wall receiving groove does not change, so the temperature changes Can prevent the appearance of the bathroom from changing. In addition, when the temperature changes after the construction of the bathroom, the characteristics of the wall material that the position is difficult to change because it is fixed to the floor base material, and the characteristics of the silicone that the width is difficult to change and the adhesive surface is difficult to peel off, As a result, the amount of deformation of the floor material to be expanded and contracted substantially matches the amount of displacement of the wall material.

  According to the aspect of the present invention, there is provided a bathroom structure that can suppress the influence on the positioning of the wall panel or the like or can maintain the assemblability even when the plane dimension changes due to expansion and contraction.

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 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.

  In the washing floor pan 100, a drain outlet (closed with a removable lid 155 in FIG. 1) communicating with the drain pipe 5 is formed in the vicinity of the boundary with the bathtub 200. The portion provided with the drainage port is recessed, and the surface of the washing floor floor pan 100 is provided with a drainage slope inclined downward toward the drainage port. On the back side of the washing floor floor pan 100, the drain pipe 5 is provided in the vicinity of the boundary with the bathtub 200, and the drain outlet is connected to the drain pipe 5. A drain outlet (not shown) provided at the bottom of the bathtub 200 is also connected to the drain pipe 5.

  The wall 300 constitutes four surfaces of the bathroom unit and has first to sixth wall panels 310 to 360 which are wall materials of the present invention, and adjacent wall panels are adjacent to each other. A wall surface connecting member 305 that connects them is erected on the outer peripheral portion 100 a of the washing 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 also one of the wall materials of the present invention.

In addition, the structure of the wall surface material in this invention is not limited only to this, The structure by which one panel is divided | segmented into several panels, and the structure by which several adjacent panels are integrated may be sufficient. .
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 the present invention, the wall panel 330 including the door mounting frame is also included in the wall surface material.

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

  As shown in FIG. 2, a drain port opening 131 communicating with the drain pipe is formed in the vicinity of, for example, the outer peripheral portion on the long side of the floor material 130. The portion provided with the opening 131 has a concave shape. In addition, a drainage gradient inclined downward toward the opening 131 is formed on the surface of the floor member 130.

  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.

The drain pit 160 is formed of a resin having a hardness higher than the hardness of the floor surface material 130 and has a water-impermeable property. In other words, the drain pit 160 is formed of a resin having a foaming rate lower than that of the thermoplastic foamed resin of the floor material 130. Specifically, the drain pit 160 is formed of a non-foaming resin.
Here, in this specification, “hardness” refers to the hardness (hardness) determined by either the “Rockwell hardness” test method or the “Shore hardness” test method.

  The drain pit 160 is attached to the opening 131 of the floor surface material 130. Further, the drainage pit 160 has an opening 165 and forms at least a part of the drainage port. The drain pit 160 has a flange portion at the upper end. The flange portion is in contact with the lower surface of the surface material 150 and is joined to the lower surface of the surface material 150 by, for example, vibration welding, adhesion using an adhesive, or adhesion using IH (induction heating).

FIG. 3 is an enlarged schematic cross-sectional view of the vicinity of the wall receiving groove portion on which the wall surface material of the present embodiment is placed.
FIG. 3 is a schematic cross-sectional view taken along the cutting plane 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.

  The outer edge portion 134 of the floor surface member 130 has a recessed portion in which the wall surface material is inserted, a standing wall that becomes a waterproof wall, etc., and forms a water stop structure for a connection portion with the bathroom floor surface. A groove part 135 is provided. The lower portion of the first wall panel 310 corresponding to the wall surface material is inserted into the concave portion of the wall receiving groove portion 135, and the bent portion 313 a of the steel plate 313 is directly on the bottom surface of the concave portion provided in the wall receiving groove portion 135 of the floor surface material 130. Or it will be in the state contact | abutted via packing. In a state where the first wall panel 310 is erected, a caulking material CK for waterproofing is provided in a gap between the recess and the steel plate 313 of the first wall panel 310. The caulking CK prevents water in the bathroom from flowing into the back side of the wall panel 310. The caulking CK is, for example, silicone. In this case, the silicone bonds the first wall panel 310 and the side of the wall receiving groove 135 inside the bathroom.

  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. 3, the floor surface material 130 of the present embodiment is easily expanded and contracted due to a change in temperature. And the planar dimension of the floor covering 130 may change. Then, the wall receiving groove 135 may expand and contract due to a change in temperature, and the position of the first wall panel 310 may change. Then, the assemblability including the positioning operation of the first wall panel 310 may be deteriorated.

On the other hand, in this 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 of the base material 311 and the steel plate 313 combined).
The concave portion of the wall receiving groove portion 135 has a width D1 in which the first wall panel 310 supported by the wall surface connecting member 305 fits into the concave portion of the wall receiving groove portion 135 even when the floor material 130 expands and contracts. A dimension D3 of a gap between the steel plate 313 and the side portion inside the bathroom of the recess of the wall receiving groove 135 is, for example, about 2 millimeters (mm) to 4 mm. Moreover, the dimension D4 of the clearance gap between the steel plate 313 and the side part of the recessed part of the wall receiving groove part 135 on the bathroom outer side (the side opposite to the washing place) is, for example, about 1.5 mm to 3.5 mm.

  In the description related to FIG. 3, the first wall panel 310 is taken as an example of the wall surface material, and the structure in the vicinity of the wall receiving groove portion 135 on which the first wall panel 310 is placed is given as an example. These structures are the same as the structures of the second wall panel 320 and the third wall panel 330 and the wall receiving groove portion 135 on which the second wall panel 320 and the third wall panel 330 are placed. .

FIG. 6 is a schematic cross-sectional view taken along line AA shown in FIG.

  As shown in FIG. 4, the wall surface fixing member 307 of this embodiment is fixed around the floor base material 110. The wall surface connecting member 305 is held by a wall surface fixing member 307 fixed around the floor base material 110. In the example of the installation form shown in FIG. 4, a total of five wall surface connection members 305 are attached by wall surface fixing members 307 to the peripheral central portions corresponding to the respective corners and long sides of the floor base material 110. . However, as long as the wall surface fixing member 307 is fixed around the floor substrate 110 and the wall surface connection member 305 is held by the wall surface fixing member 307, the installation form of the wall surface fixing member 307 and the wall surface connection member 305 is limited to this. Not.

  As shown in FIG. 5, the wall surface fixing member 307 of the present embodiment is a substantially L-shaped metal fitting, for example, and is fixed to the receiving plate 115 of the floor base 110 by fastening means 309 such as bolts and screws. .

  Specifically, as shown in FIG. 6A, the wall surface fixing member 307 is fixed to the receiving plate 115 of the floor base 110 by the fastening means 309, and the wall surface connecting member 305 is fastened to the rising side 307a. It is fixed with. Since the floor base 110 has a predetermined strength sufficient to support the wall panel, the wall surface fixing member 307 can be firmly fixed.

  Alternatively, as illustrated in FIG. 6B, the wall surface fixing member 307 is fixed to the receiving plate 115 and the support frame 113 of the floor base material 110. That is, the receiving plate 115 is fixed to the first frame 113a of the support frame 113 by fastening means 309 such as screws. The wall surface fixing member 307 is fastened together with fastening means 309 such as screws. The wall surface connecting member 305 is fixed to the rising side 307 a of the wall surface fixing member 307.

  Alternatively, as illustrated in FIG. 6C, the receiving plate 115 is disposed inside the first frame 113a, and the wall surface fixing member 307 is fixed to the first frame 113a. The receiving plate 115 is disposed inside the first frame 113a, and the surface of the receiving plate 115 is flush with the upper surface of the first frame 113a. That is, the first frame 113 a is disposed at a position corresponding to the outer edge portion 134 of the floor surface material 130. Therefore, the wall surface fixing member 307 is directly fixed to the first frame 113 a corresponding to the outer edge portion 134. The wall surface connecting member 305 is fixed to the rising side 307 a of the wall surface fixing member 307.

FIG. 7 is a schematic cross-sectional view showing a fitting structure between the wall surface connecting member and the wall panel of the present embodiment.
In FIG. 7, a cross section along a direction orthogonal to the standing direction of the wall surface connecting member 305 is shown. Fig.7 (a) has illustrated the fitting structure of two wall panels adjacent on the same plane, and the wall surface connection member provided between these. FIG.7 (b) has illustrated the fitting structure of the two wall panels orthogonal at a corner part, and the wall surface connection member provided between these.
In the following description, the wall surface connection member 305A illustrated in FIG. 7A and the wall surface connection member 305B illustrated in FIG. 7B are collectively referred to as the wall surface connection member 305.

The wall surface connecting member 305 has a hollow structure in which a thin plate is bent, and the left and right folded portions 305a have a spring property.
FIG. 7A illustrates an attached state of the two wall panels 310-1 and 310-2 constituting the first wall panel 310. On the left and right side surfaces of the steel plates 313 of the two wall panels 310-1 and 310-2, the folded portions 305b-1 and 305b-2 to the back side having spring properties are provided.

To attach the two wall panels 310-1 and 310-2 to the wall surface connecting member 305A, the folded portions 305b-1 and 305b-2 are fitted between the left and right folded portions 305a of the wall surface connecting member 305. The folded portions 305b-1 and 305b-2 are fitted so as to push between the left and right folded portions 305a.
When the folded portions 305b-1 and 305b-2 are fitted, the two wall panels 310-1 and 310-2 are fixed to the same surface with the wall surface connecting member 305A interposed therebetween.

FIG. 7B illustrates the mounting state of the first wall panel 310 and the second wall panel 320, but the mounting state is different from FIG. 7A only in the mounting angle of the two wall panels. Since the basic structure adopts the same concept, the description is omitted.
When the folded portions 305b-1 and 305b-2 are fitted, the two wall panels 310 and 320 are fixed to be orthogonal to each other with the wall surface connection member 305B interposed therebetween.

  As described above, the folded portion 305a of the wall surface connection member 305 and the folded portions 305b of the wall panels 310 and 320 have spring properties in the plane (horizontal) direction orthogonal to the wall 300, and therefore the mutual installation positions are The engagement is fixed and has a shape that regulates the position in the vertical direction and is freely movable. Therefore, when the wall panels 310 and 320 are fitted into the wall surface connection member 305, they fall downward due to their own weights, and the lower ends (folded portions 313a) abut against the recesses of the wall receiving groove portions 135 of the outer edge portion 134 of the floor material 130. Touch.

  As described above, the floor material 130 formed of a thermoplastic foam resin expands and contracts due to changes in temperature, and thus has a characteristic that the size (planar dimension) varies depending on the season. On the other hand, the wall surface fixing member 307 of this embodiment holds the wall surface connection member 305 that is fixed to the floor base material 110 and supports the wall surface material. Therefore, the wall surface material is not affected by a change in the size of the floor surface material 130 and is installed at a regular position. Further, the wall receiving groove portion 135 provided at the peripheral end portion of the floor main body 120 (the outer edge portion 134 of the floor surface material 130) is supported at a normal position by the wall surface connecting member 305 even when the floor surface material 130 expands and contracts. And has a width D1 capable of receiving the lower end of the wall material. Therefore, even if the common floor material 130 is used in different seasons, the size of the assembled bathroom does not change, and the bathroom can be assembled with higher accuracy.

  Further, when the caulking CK is silicone, the change in the width of the gap D3 between the inner surface of the wall surface of the wall material (the surface of the steel plate 313) and the inner side of the concave portion of the wall receiving groove 135. The amount can be kept smaller. That is, when the temperature changes, the amount of change in the size of the floor base material 110 is smaller than the amount of change in the size of the floor covering 130. The silicone is filled and bonded between the lower end portion of the wall surface material fixed to the floor base material 110 whose amount of change is smaller than that of the floor surface material 130 and the wall receiving groove portion 135. The width of silicone is unlikely to change even when temperature changes occur. Therefore, even if the floor covering 130 is greatly expanded and contracted after construction, the width of the gap D3 between the wall inner surface of the wall material and the inner side of the recess of the wall receiving groove 135 does not change. It is possible to prevent the appearance of the bathroom from changing due to temperature changes. Furthermore, when the temperature changes after the construction of the bathroom, the wall material has a characteristic that the position is difficult to change because it is fixed to the floor base material 110, and the width is difficult to change, and the adhesive surface is difficult to peel off. In combination with the characteristics of silicone, the amount of deformation of the floor material 130 to be expanded and contracted substantially coincides with the amount of displacement of the wall material.
