  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a schematic cross-sectional view showing a bathroom wall panel mounting structure according to a first embodiment of the present invention.

  The bathroom wall panel mounting structure according to the embodiment of the present invention is a so-called flat joint mounting structure applied to a pair of wall panels 30a and 30b that are substantially flush with each other in the bathroom. The wall panel 30 a and the wall panel 30 b are attached to the support member (flat joiner) 10 via the panel joiner 20.

  The column member 10 has a structure in which, for example, a long steel plate is bent into a hollow column shape. The strut member 10 includes a back surface portion 11 and a back surface portion 11 which are located apart from both wall panels 30a and 30b on the back side of the adjacent portion of the wall panel 30a and the wall panel 30b (the side opposite to the bathroom 100). A pair of side surface portions 12 extending toward the back sides of the wall panels 30a and 30b and facing substantially parallel to each other, and a bent portion 13 that is provided following the tip of each side surface portion 12 and is bent inside the side surface portion 12. These are integrally formed.

  The pair of bent portions 13 oppose each other with an opening 5 communicating with the hollow interior of the column member 10. Each bent portion 13 has an inclined portion 14 that enters the support member 10 from the opening 5. The inclined portion 14 is inclined so as to gradually approach the side surface portion 12 as it enters the support member 10 from the opening 5 side.

  Next, the panel joiner 20 will be described with reference to a perspective view shown in FIG. 2 in addition to FIG.

  The panel joiner 20 is configured as a long member having an approximately “Ω” cross section made of a medium-hard material that can be elastically deformed, and includes a back surface portion 22, a curved portion 21, and a wing portion 25. The back surface portion 22 of the panel joiner 20 is located between the back surface portion 11 of the column member 10 and the wall panels 30a and 30b, and extends from the back surface portion 22 toward the wall panels 30a and 30b to form a pair of curved portions. 21 is provided. The wing portion 25 extends outward from the tip of the side surface portion 21 and is further bent in a direction away from the wall panels 30a and 30b. The back surface portion 22, the curved portion 21, and the wing portion 25 are integrally provided.

  A seal portion 26 made of an elastically deformable soft material is provided on the inner side facing the bathroom 100 in the back surface portion 22 of the panel joiner 20. The seal portion 26 has a “Y” or “V” -shaped cross-sectional shape in which the tip on the bathroom 100 side is divided into two.

  The wall panels 30a and 30b have a surface material 31 backed with a backing material 32 such as plaster. As shown in FIG. 3, the surface material 31 is formed by, for example, bonding a resin layer 42 to a steel plate 41, and a coating layer 43 is formed on the surface of the resin layer 42 that faces the bathroom.

  By forming the coating layer 43 on the surface of the surface material 31, unevenness on the surfaces of the wall panels 30a and 30b can be reduced and the smoothness can be improved. Thereby, even if dirt is attached to the wall panels 30a and 30b, it is easy to remove and the cleaning efficiency is improved. Furthermore, the coating layer 43 has water repellency (for example, a contact angle of water of 90 ° or more), and the surface of the wall panels 30a and 30b is hardly soiled, and even if soiled, it does not remain for a long time. Or the coating layer 43 which has hydrophilicity may be formed in the surface of the surface material 31, and an antifouling effect is acquired also in this case.

  By projecting the side end portion of the surface material 31 into a substantially “J” shape on the side opposite to the surface facing the bathroom 100, a projecting portion 33 having spring properties is configured. The projecting portion 33 includes a side surface portion 34 bent to the opposite side of the bathroom 100 at a substantially right angle with respect to the surface facing the bathroom 100 in the surface material 31, and a back surface portion bent inward from the distal end of the side surface portion 34. 35 and a folded portion 36 that is folded back from the tip of the back surface portion 35 toward the back surface side of the surface material 31.

  The column member 10, the panel joiner 20, and the wall panels 30a and 30b described above are connected to each other as described below.

  The column member 10 is erected on the washing floor, the bathtub-side floor pan, the bathtub rim, or the like according to the position where the wall panels 30a and 30b are installed with the opening 5 facing the bathroom 100 side. .

  The back surface portion 22 and the curved portion 21 of the panel joiner 20 enter the inside of the support member 10 from the opening 5 of the support member 10, and the wing portion 25 extends from the front end portion to the side surface portion 12 of the bent portion 13 of the support member 10. Engage so as to surround from the outside of the column member 10.

  The inner surface 22 of the panel joiner 20 faces the inner surface 11 of the column member 10 inside the column member 10. The portion near the convex portion 23 in the bending portion 21 elastically contacts the inner surface of the inclined portion 14 of the bent portion 13 of the support column member 10, whereby the bending portion 21 is located between the pair of bent portions 13 inside the support column member 10. It will be in the state fitted to.

  The protrusions 33 of the wall panels 30a and 30b are fitted inside the curved portion 21 of the panel joiner 20 with the side surfaces 34 facing each other. The seal part 26 of the panel joiner 20 elastically contacts the back surface part 35 of the protrusion 33 in a state where the tip part divided into two is expanded from the natural state. That is, the seal part 26 of the panel joiner 20 is elastically elastic when the protrusions 33 of the wall panels 30a and 30b are inserted and fitted inside the curved part 21, and the protrusions 33 are elastic in the direction opposite to the insertion direction. As a result, the folded portion 36 of the protrusion 33 is pressed against the inner surface of the curved portion 21 of the panel joiner 20, and the wall panels 30 a and 30 b are firmly attached to the column member 10 via the panel joiner 20. Fixed.

  The seal portion 26 is made of a waterproof material, and the seal portion 26 is in elastic contact with the back surface portion 35 of the projection 33 of the wall panels 30a and 30b, thereby leaking hot water to the back side of the wall panels 30a and 30b. Is prevented.

  As described above, when the surface layer 31 is provided with the coating layer 43 having functions such as improving the smoothness of the surface or having water repellency in order to impart antifouling properties to the wall panels 30a and 30b, the surface thereof This is because the contact portion between the protrusion 33 formed by bending the side end portion of the material 31 and the curved portion 21 of the panel joiner 20 easily slips, and the wall panels 30a and 30b easily come off the panel joiner 20. The inventors have learned.

  In order to make it difficult to remove the wall panels 30a and 30b fitted to the panel joiner 20, it is conceivable to increase the fitting force in the fitting portion by changing the design of the dimensions and shape of each member. It becomes difficult to remove the wall panels 30a and 30b during remodeling, etc., and preparing parts specially designed for wall panels with the coating layer 43 formed reduces the versatility of the parts, and further manufacture And parts management become complicated, leading to an increase in manufacturing costs.

  At present, in consideration of production efficiency, the surface material 31 of the wall panels 30a and 30b is formed by collectively forming the resin layer 42 and the coating layer 43 on the steel plate 41 having a size corresponding to a plurality of wall panels. Thus, the protrusion 33 is processed by being divided into a plurality of sheets and bending the side end portions of the divided surface material 31. At this time, it may be possible not to form the coating layer 43 by masking the surface of the portion that should become the protrusion 33, but the coating layer 43 is not formed or removed only on the protrusion 33. This means that the number of extra steps is increased, and in the state of a large steel plate before division, it is difficult to recognize which portion is bent after division and becomes the protrusion 33.

  Therefore, in the present embodiment, the anti-slip means 50 (represented by hatching in FIG. 2) is provided at a portion where the protrusions 33 of the wall panels 30a and 30b come into contact with the curved portion 21 of the panel joiner 20. Specifically, the slip prevention means 50 is made of, for example, a resin-based material applied to a portion in the vicinity of the convex portion 23 in the curved portion 21 where the folded portion 36 of the projection 33 of the wall panels 30a and 30b contacts.

  By providing the slip prevention means 50, even if the coating layer 43 is formed on the surface of the protrusion 33 in consideration of productivity, the slip at the contact portion between the protrusion 33 and the curved portion 21 of the panel joiner 20 is prevented. It is possible to prevent the protrusion 33 from being undesirably detached from the panel joiner 20. That is, according to the present embodiment, it is possible to ensure a stable mounting state of the wall panels 30a and 30b while giving added value such as surface antifouling property to the wall panels 30a and 30b.

  The anti-slip means 50 is not limited to the one applied to the bending portion 21, but a tape-like one attached to the bending portion 21, or the surface of the bending portion 21 is subjected to, for example, sanding treatment, blasting treatment, or chemical treatment. And roughened surface.

  The slip preventing means 50 is not limited to being provided at the curved portion 21 of the panel joiner 20, but may be provided at the folded portion 36 that is a portion that contacts the curved portion 21 at the projection 33 of the wall panels 30 a and 30 b.

  However, it is not easy to perform the anti-slip treatment as described above on the bent portion, and when the anti-slip means 50 is provided in a state before the surface material 31 is divided, it is necessary to It is difficult to recognize whether this part is bent to become the protrusion 33, and the wall panel after division is not necessarily provided in the flat joint part in the bathroom, and a fitting structure with the panel joiner 20 is adopted. Since it may be provided at a corner joint portion that is not provided, it is desirable to provide the anti-slip means 50 on the curved portion 21 of the panel joiner 20 as in the above-described embodiment. In this way, the wall panels 30a and 30b can be mass-produced with high versatility in the same manner as before, and the manufacturing cost is not increased.

  In consideration of workability, it is easier to provide the slip prevention means 50 over the entire inner surface of the curved portion 21 of the panel joiner 20 or over a relatively wide range. However, in order to prevent the protrusion 33 of the wall panels 30a, 30b and the curved portion 21 of the panel joiner 20 from slipping, at least a portion where the protrusion 33 and the curved portion 21 are in contact with each other is provided with a non-slip means 50. Good.

  The anti-slip means 50 is not provided on the opening 5 side (entrance side) from the contact portion of the panel joiner 20 with the protrusions 33 of the wall panels 30a, 30b. If it is provided only in the contact portion, the slip prevention means 50 does not become a resistance when the folding portion 36 of the protrusion 33 is pushed inward while being in contact with the inner surface of the bending portion 21, but rather on the surface of the folding portion 36. The pushing-in operation can be easily performed by utilizing the sliding property of the formed coating layer 43.

  Further, even when the protrusion 33 is pulled out from the opening 5 toward the bathroom 100 and is detached from the bending portion 21, the slip prevention means 50 exists in the portion of the bending portion 21 closer to the opening 5 than the contact portion with the protrusion 33. Without slipping, the slip prevention means 50 does not become a resistance when the folding part 36 of the protrusion 33 is brought into contact with the inner surface of the curved part 21 and is pulled out to the bathroom 100 side. Rather, the coating formed also on the surface of the folding part 36 The removal work of the wall panels 30a and 30b can be easily performed by utilizing the slipperiness of the layer 43.

  In addition, even if the slip prevention means 50 exists in the back | inner side rather than the contact part with the protrusion 33 in the panel joiner 20, attachment and removal of wall panel 30a, 30b are not prevented.

  It is preferable not to provide an anti-slip means at a portion of the projection 33 of the wall panel 30a, 30b that contacts the seal portion 26 of the panel joiner 20. The seal portion 26 is elastically brought into close contact with the back surface portion 35 of the projection 33 of the wall panels 30a and 30b, thereby preventing leakage of hot water to the back side of the wall panels 30a and 30b. This is because if the stopping means is provided, the water tightness may be deteriorated.

  The panel joiner 20 is a mediating member for supporting the wall panels 30a and 30b on the support member 10, and also functions as a part of the framework of the bathroom unit. Therefore, the panel joiner 20 needs to be rigid. If the anti-slip means provided separately from the panel joiner 20 is made hard, the wall panels 30a and 30b are hard to attach and remove (requires an excessive force compared to the prior art). It is necessary to use a material that is softer than the joiner 20 and the wall panels 30a and 30b or that can be deformed by receiving a pressure contact force with the protrusions 33 of the wall panels 30a and 30b.

  As specific examples of the slip prevention means, a paint having anti-slip properties such as pine crab applied to the panel joiner 20, an adhesive material such as Pef paint, silicon, a hard panel joiner 20, Another member for fitting, which is interposed so as to come into contact with the contact portions of the wall panels 30a and 30b with the protrusions 33, and the like are mentioned. As a characteristic common to such slip prevention means, the rigid panel joiner 20 and the wall It can be said that the frictional force (specifically, surface roughness or adhesive force) is larger than the surface of the contact portion in the panels 30a and 30b.

  Further, a member that fits the folded portion 36 is interposed as a slip preventing means in the gap between the panel joiner 20 and the folded portion 36 of the wall panels 30a and 30b, and the gap between the two is reduced. You may try to stop.

  The anti-slip means is not limited to being separate from the panel joiner 20, and may be configured such that the anti-slip means and the panel joiner 20 are integrated.

  For example, the anti-skid means may be configured by making the thickness of the contact portion of the panel joiner 20 with the projection 33 of the wall panels 30a, 30b thicker than other portions. In this case, if the portion on the opening 5 side (entrance side) of the panel joiner 20 is made thicker than the portion thickened as the slip prevention means, it becomes difficult to attach and remove the wall panels 30a and 30b. The portion to be thickened as the stopping means (the contact portion with the protrusion 33) can be defined as being thicker than the portion on the opening 5 side (inlet side) than the slip preventing means.

  Further, the anti-skid means is formed by forming, for example, irregularities so that the frictional force (surface roughness) of the contact portion of the panel joiner 20 with the protrusions 33 of the wall panels 30a, 30b is larger than that of other portions. Also good. Also in this case, from the viewpoint of facilitating the attachment and removal of the wall panels 30a and 30b, the portion that increases the frictional force as the slip prevention means (the contact portion with the projection 33) is closer to the opening 5 than the slip prevention means. It can be defined that the frictional force (surface roughness) is larger than the part.

  In addition, the frictional force (surface roughness or adhesive force) of the portions of the panel joiner 20 that are in contact with the projections 33 of the wall panels 30a, 30b is partially changed so that the frictional force (surface roughness or adhesive force) of the portions of the wall panels 30a, 30b The slip prevention means may be configured so as to be larger than the frictional force (surface roughness or adhesive force) of the protrusion 33 in contact with the panel joiner 20.

  The slip prevention means may be provided not on the panel joiner 20 but on the side of the wall panels 30a and 30b. For example, the coating layer 43 of the contact portion (specifically, the entire folded portion 36 or the entire protrusion 33) of the wall panels 30a and 30b with the panel joiner 20 is peeled off, and the surface roughness of the contact portion is determined by the wall panel 30a. , 30b may be configured to be larger than the surface roughness of the portion facing the bathroom 100 (the portion where the coating layer 43 is formed) in 30b.

  One of the characteristics required for the coating layer 43 that imparts antifouling properties to the wall panels 30a and 30b is surface smoothness. In order to obtain the antifouling property, the surface roughness of the coating layer 43 surface is 1.5 (nm) or less, preferably 1 (nm) or less, more preferably 0.5 (more than 0.5 (nm) in a range larger than 0 (nm). nm) or less. The conventional product in which a PET / polyester film was laminated 2 nm or more on the surface of the steel plate was inferior in antifouling property to the wall panel formed with the coating layer 43 in this embodiment.

  Moreover, also when the coating layer 43 has water repellency, antifouling property can be provided to the wall panels 30a and 30b. As such a coating layer 43, an antifouling paint having a water-repellent functional group (methyl group) can be used. The contact angle with water in the coating layer 43 having such water repellency is 90 ° or more, preferably 100 ° or more in a range smaller than 180 °. In the conventional product in which a PET / polyester film was laminated on the surface of the steel plate, the contact angle with water was about 80 °, and the antifouling property was inferior to the wall panel formed with the coating layer 43 in this embodiment. . In the case where the coating layer 43 has water repellency, in particular, slipping at the contact portion with the panel joiner 20 described above is likely to occur, and it is particularly effective to apply the above-described slip prevention means to such a case.

  Moreover, also when the coating layer 43 has hydrophilicity, antifouling property can be provided to the wall panels 30a and 30b. As such a coating layer 43, an antifouling paint having a hydrophilic group (such as a hydroxyl group) can be used. The contact angle with water in the hydrophilic coating layer 43 is 20 ° or less, preferably 10 ° or less in a range larger than 0 °.

[Second Embodiment]
FIG. 4 is a schematic cross-sectional perspective view showing the bathroom wall panel mounting structure according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same component as 1st Embodiment mentioned above, and the detailed description is abbreviate | omitted.

  In the present embodiment, the anti-slip means 60 is interposed between the side surfaces 34 of the projections 33 of the wall panels 30a and 30b that are superimposed on each other and are fitted inside the curved portion 21 of the panel joiner 20. .

  The anti-slip means 60 is, for example, in the form of a tape, but is not limited thereto, and may be a resin-based material applied to the surface of the side surface portion 34 of the pair of protrusions 33 facing the other, or The surface of the side surface portion 34 of the pair of protrusions 33 facing the other may be roughened by, for example, sanding treatment, blast treatment, or chemical treatment, and may be used as the anti-slip means 60. Thus, by providing the non-slip means 60 on the surface of the side surface portion 34 of the pair of protrusions 33 facing the other, the adhesion between the side surface portions 34 of the pair of protrusions 33 is increased, and the gap between them is increased. Since it becomes small, it becomes possible to provide water-stopping.

  According to the present embodiment, even if the coating layer 43 is formed on the surface of the protrusion 33 in consideration of productivity, the protrusion 33 can be prevented from slipping, and the protrusion 33 can be controlled by the panel joiner 20. Can be prevented from undesirably coming off. That is, also in the present embodiment, it is possible to ensure a stable mounting state of the wall panels 30a and 30b while giving added value such as surface antifouling property to the wall panels 30a and 30b.

  In addition, the slip prevention means 50 is provided in the contact part of the protrusion 33 and the curved part 21 of the panel joiner 20 like 1st Embodiment, and also between the side parts 34 of the protrusion 33 like 2nd Embodiment. In addition, if the slip prevention means 60 is provided, the fitting state between the protrusion 33 and the panel joiner 20 can be maintained more stably. This is because when a strong fitting force between the wall panels 30a, 30b and the panel joiner 20 is required (for example, a handrail is attached to the wall panels 30a, 30b, and the user applies a load to the handrail, etc.) On the other hand, it is effective when a large force is assumed to be applied in the direction of being pulled out from the panel joiner 20.

It is a schematic cross section showing the attachment structure of the bathroom wall panel which concerns on the 1st Embodiment of this invention. It is a perspective view of the principal part of the panel joiner represented in FIG. It is a schematic diagram showing the structure of the surface material in the wall panel shown in FIG. It is a typical section perspective view showing attachment structure of a bathroom wall panel concerning a 2nd embodiment of the present invention.
