Further, as shown in FIGS. 10C and 10D, the small diameter portion 114 is fitted in the narrow groove portion 123 and is movable.

(Assembly process)
A method for assembling the wall panel for assembling the wall panel of the bathroom unit having the above-described configuration will be described along the assembling process. The two first wall panels 95 and second wall panels 96 at the corners constituting the wall panel of the bathroom unit are placed on the floor 6 of the bathroom unit in a direction orthogonal to each other, as in the first embodiment. The process of temporarily installing in the temporarily connected state is performed (see FIG. 1).

  Next, the second wall panel 96 and the third wall panel 97, which are connected side by side and linearly (referred to as a flat joint), are in a state where the upright portions 98 face each other as shown in FIG. Then, temporarily install it on the floor 4 such as a bathroom pan.

  Next, as shown in FIG. 12A, the left and right wall abutting portions 136 of the inner connecting member 121 are placed between the upright portions 98 of the second wall panel 96 and the third wall panel 97, between them. It arrange | positions so that the folding | returning part 99 and the connection material contact part 100 may be located. In this state, the left and right front portions 135 of the inner connecting member 121 are in contact with the back surfaces of the second wall panel 96 and the third wall panel 97.

  Next, as shown in FIGS. 10A and 11A, the outer connecting member 112 is brought close to the inner connecting member 121 from the back side, and as shown in FIG. Are inserted into the inner connecting member 121 through the left and right openings 130 of the back portion 127 of the inner connecting member 121, and the small diameter portions 114 of the left and right projecting portions 113 are respectively inserted into the groove portions 122 of the inner connecting member 121. insert.

  Then, as shown in FIG. 11B, when the outer connecting member 112 is hit from above with a mallet or the like, the small diameter portions 114 of the left and right projections 113 are respectively within the narrow groove portion 123 and the left and right projections 113. Each of the large diameter portions 115 moves along the inner surfaces of the left and right side portions 128 of the inner connecting member 121 toward the front side (inside the bathroom) and obliquely downward. As shown in c), the inner coupling member 121 is fitted more deeply and approaches the back portion 127 of the inner coupling member 121.

  Further, when the outer connecting member 112 is hit with a wooden mallet or the like from above, the outer connecting member 112 moves to the front side, and the left and right pressing portions 118 of the outer connecting member 112 are respectively left and right extended portions 129 in the inner connecting member 121. Is pushed inward (the direction in which the left and right extension portions 129 approach each other), and the left and right wall contact portions 136 bring the left and right connecting material contact portions 100 closer to each other.

  For this purpose, the second wall panel 96 and the third wall panel 97 are moved so as to approach each other, and as shown in FIG. In the state, the second wall panel 96 and the third wall panel 97 are connected.

  In this method of assembling a wall panel for a bathroom, the outer connecting member 112 always urges the protrusion 113 in the groove 122 along the narrow groove 123 to the front side (inside the bathroom) and obliquely downward due to its own weight. Has been. For this reason, the outer connecting member 112 is constantly urged toward the inner connecting member 121 side.

  Therefore, the left and right side portions 117 of the outer connecting member 112 approach the left and right extended portions 129 of the inner connecting member 121 toward each other, and the left and right wall contact portions 136 are always left and right connecting member contact portions. Since the 100 is biased so as to approach each other, the second wall panel 96 and the third wall panel 97 are stably held in a state where the connection strength is increased, and are not easily released.

  Then, the upright portion 98 of the second wall panel 96 and the upright portion 98 of the third wall panel 97 are in close contact with each other via the water blocking packing 102. Therefore, a water stop effect is produced without providing a wall molding as in the prior art. Moreover, since the clearance gap between the standing part 98 of the 2nd wall panel 96 and the standing part 98 of the 3rd wall panel 97 becomes small and is not conspicuous, it comes to connect naturally and the design property improves.

(Example 5)
A fifth embodiment of the wall panel assembling method according to the present invention will be described below with reference to FIGS.

  The method of assembling the wall panel of the fifth embodiment is substantially the same as the method of assembling the wall panel of the first embodiment, but the second wall panel 146 and the third wall panel 147 that are part of the assembly method. As for the connection structure, the structures of the connecting material and the wall panel are partially different. Therefore, here, the method for assembling the wall panel according to the fifth embodiment will be described focusing on differences from the first embodiment.

  In the fifth embodiment, as shown in FIGS. 17A to 17C, the second wall panel 146 and the third wall panel 147 that are linearly connected to each other are connected to face each other. Standing portions 148 that are bent at right angles to the outside (rear side) of the bathroom are formed at the side ends.

  As shown in FIG. 17 (a), a structure having a simpler structure than the wall molding is provided on the inner surface of one or both of the rising portion 148 of the second wall panel 146 and the rising portion 148 of the third wall panel 147. If the water packing 149 is attached, when the second wall panel 146 and the third wall panel 147 are connected, as shown in FIG. It is possible to improve water stoppage.

  The second wall panel 146 and the third wall panel 147 are connected by a connecting member 156 as shown in FIGS. The connecting member 156 includes an inner connecting member 157 and an outer connecting member 158.

  The inner connecting member 157 is formed of a material such as an elastic metal plate or a resin plate. As shown in FIGS. 13A and 13B, the back portion 161 and the left and right ends of the back portion 161 are disposed on the front side. It consists of left and right sides 162 that are bent toward it.

  The left and right side portions 162 of the inner connecting member 157 are each provided with a deformed portion 163 that is bent and deformed so as to expand outwardly away from each other on the front side, and on the distal end side of the left and right deformed portions 163, Wall abutting portions 164 are provided that are folded at an acute angle toward the inside (to the sides facing each other).

  A plurality of notches 165 are formed in the left and right side portions 162 at intervals in the longitudinal direction (vertical direction). As shown in FIGS. 13A and 13C, the notch 165 has a horizontally long rectangle when viewed from the side (as viewed in the direction of arrow C in FIG. 13A).

  The outer connecting member 158 includes a back portion 171 and left and right side portions 172 as shown in FIGS. The outer connecting material 158 is formed in a shape in which both ends approach each other toward the end. That is, the left and right side portions 172 are formed in a shape in which the end portions (both end portions) approach each other toward the front side. The end portions of the left and right side portions 172 function as a pressing portion 173 that deforms the left and right deforming portions 163 of the inner connecting member 157 inward (in a direction approaching each other), as will be described later.

  The inner surface of the front end side of the left and right side portions 172 of the outer connecting member 158 (the surface where the left and right side portions face each other) is spaced apart in the longitudinal direction corresponding to the plurality of cutout portions 165 of the inner connecting member 157. As shown in FIG. 14A, a plurality of protrusions 176 are formed.

  As shown in FIG. 14C to FIG. 14E, the protrusion 176 has a rectangular shape when viewed from the side (as viewed in the direction of arrow C in FIG. 14B). ) To (d), it is formed of a projecting piece cut and raised from the side portion 172 to the inside (the side where the left and right side portions 172 face each other). The protrusion 176 may have a configuration in which the side portion 172 is recessed so as to protrude inward, or a configuration in which another member that protrudes inward of the side portion 172 is fixed.

  The vertical dimension of the protrusion 176 is slightly smaller than the vertical dimension of the notch 165 so that the protrusion 176 fits within the notch 165 of the inner connecting member 157 and is smoothly guided. The outer connecting member 158 has elasticity, but is manufactured from a material such as a metal material or a resin material that is more rigid than the inner connecting member 157.

  Thus, as will be described later, as shown in FIGS. 17B and 17C, in the process of fitting the outer connecting member 158 to the inner connecting member 157 from the back side, the outer connecting member 158 is elastically elastic. The left and right deformed portions 163 in the inner connecting member 157 can be elastically deformed in a direction approaching each other (inward direction) without being deformed so much.

(Assembly process)
A method for assembling the wall panel according to the present invention using the connecting member 156 having the above-described configuration will be described along the assembling process. First, the first wall panel 145 and the second wall panel 146 are temporarily installed on the floor 6 of the bathroom unit in a direction orthogonal to each other, as in the case of the first embodiment (see FIG. 1).

  Next, as shown in FIG. 17A, the second wall panel 146 and the third wall panel 147 are temporarily installed on the floor 4 such as a bathroom pan with the upright portions 148 facing each other. Then, the inner connecting member 157 is viewed from the rear side so that the upright portions 148 of the second wall panel 146 and the third wall panel 147 are positioned between the left and right wall abutting portions 164. Arrange as shown in (a).

  Next, the outer connecting member 158 is brought closer to the inner connecting member 157 from the back side, and as shown in FIGS. 15A and 17B, the pressing portions 173 of the left and right side portions 172 of the outer connecting member 158 are arranged. The inner connecting member 157 is fitted therebetween.

  Then, when the outer connecting member 158 is moved by hitting the back portion 171 to the inner connecting member 157 side with a mallet, the left and right protrusions 176 of the outer connecting member 158 are moved to the left and right cutout portions 165 of the inner connecting member 157. The outer connecting member 158 fits deeper into the inner connecting member 157 by being fitted and guided by the notch 165.

  In this process, the left and right pressing portions 173 of the outer connecting member 158 elastically deform the left and right deforming portions 163 of the inner connecting member 157 in a direction to approach each other against elasticity. Then, the left and right wall contact portions 164 of the inner connecting member 157 are in contact with the upright portions 148 of the second wall panel 146 and the third wall panel 147, respectively, and are further bent by being elastically deformed into an acute angle state. The left and right upright portions 148 are pressed against each other via the water-stopping packing 149 by the elasticity of the left and right wall contact portions 164 bent in this way.

  When the left and right protrusions 176 of the outer connecting member 158 are guided to the front end surfaces of the left and right cutout portions 165 of the inner connecting member 157, the outer connecting member 158 is deepest with respect to the inner connecting member 157. The state is engaged.

  As a result, as shown in FIGS. 16 (a), 16 (b), and 17 (c), the second wall panel 146 and the third wall panel 147 are mutually moved by the elasticity of the left and right wall contact portions 164. The upright portions 148 are in close contact with each other via the water stop packing 149 and are connected.

  According to this method for assembling the wall panel, the inner connecting member 157 urges the right and left standing parts 148 of the second wall panel 146 and the third wall panel 147 from the left and right by its elasticity, They are brought into close contact with each other through packing 149. Therefore, even if a wall molding is not provided as in the prior art, if a simple water stop packing 149 is attached to the upright portion 148 as shown in FIGS. 17A to 17C, the water stop effect is improved. To do.

  Further, according to this method of assembling the wall panel, the gap between the rising portion 148 of the second wall panel 146 and the rising portion 148 of the third wall panel 147 is small and inconspicuous. As a result, the design is improved.

  Then, when the outer connecting member 158 is fitted to the inner connecting member 157 and pushed into the front side, the protrusion 176 is guided by being fitted into the notch 165 of the inner connecting member 157. The outer connecting member 158 can be smoothly performed without sliding in the vertical direction with respect to the inner connecting member 157.

  Furthermore, in the connected state of the second wall panel 146 and the third wall panel 147, the protrusion 176 is fitted in the notch 165 of the inner connecting member 157, so that the inner connecting member 157 Even if a relative external force is applied between the outer connecting members 158 in the vertical direction, the inner connecting member 157 and the outer connecting member 158 are less likely to be displaced from each other in the vertical direction, so that a stable connected state can be maintained. It becomes.

(Example 6)
A sixth embodiment of the wall panel assembling method according to the present invention will be described below with reference to FIGS.

  The method of assembling the wall panel of the sixth embodiment is substantially the same as the method of assembling the wall panel of the first embodiment, but the second wall panel 186 and the third wall panel 187 that are part of the assembly method. As for the connection structure, the structures of the connecting material and the wall panel are partially different. Therefore, here, the method for assembling the wall panel of the sixth embodiment will be described focusing on differences from the first embodiment.

  In the sixth embodiment, as shown in FIGS. 22A and 22B, the second wall panel 186 and the third wall panel 187 that are connected side by side and linearly are connected to face each other. A substantially L-shaped upright portion 188 bent at a right angle toward the back side (outside the bathroom) is formed at each side end.

  Then, a water-stopping packing 189 having a simpler structure than that of the wall molding is attached to one or both of the rising portions 188 of the second wall panel 186 and the rising portions 188 of the third wall panel 187.

  The second wall panel 186 and the third wall panel 187 are connected by a connecting member 196 as shown in FIGS. Specifically, the connecting member 196 is fitted to the back surfaces of the two wall panels 5 and 6 across the second wall panel 186 and the third wall panel 187, as shown in FIG. 22 (b). The second wall panel 186 and the third wall panel 187 are connected to each other.

  Although the details will be described later, when the second wall panel 186 and the third wall panel 187 are linearly coupled side by side, the inner coupling member 197 has a second wall as shown in FIG. The upright part 188 of the panel 186 and the upright part 188 of the third wall panel 187 are arranged at positions sandwiching from the left and right. Then, the outer connecting member 198 is fitted and overlapped on the back side of the inner connecting member 197, and the rising portions 188 of the second wall panel 186 and the third wall panel 187 are sandwiched by the inner connecting member 197.

  The inner connecting member 197 is formed of a material such as an elastic metal plate or a resin plate. As shown in FIGS. 18A and 18B, the back portion 201 and the left and right ends of the back portion 201 are disposed on the front side. Left and right side parts 202 bent toward each other, left and right front parts 203 facing each other and spaced from the left and right side parts 202, and left and right side parts 202 bent from the left and right front parts 203 toward the back part 201 Wall abutting portion 204.

  As shown in FIG. 18A, a plurality of protrusions 205 are formed at intervals in the vertical direction at 206 in the substantially central portion in the front-rear direction of the left and right side portions 202. As will be described later, when the outer connecting member 198 is fitted and overlapped on the back surface side of the inner connecting member 197, the protrusions 205 are formed inside the outer connecting member 198 as shown in FIGS. 18 (d) and 22 (b). By abutting against the wall surface, the left and right side portions 202 are deformed inward by applying an external force from the left and right outer sides to the inner side.

  Considering this, the left and right side portions 202 that are deformed inward by an external force applied from the left and right outer sides are also referred to as “deformed portions” in the sixth embodiment. Hereinafter, the left and right side portions 202 of the inner connecting member 197 are expressed as deformed portions, and the deformed portions are denoted by the same reference numerals 202 as the side portions 202.

  The protrusion 205 can have various structures. As shown in FIG. 18C, the protrusion 205 of the sixth embodiment is provided with two notches 207 in parallel to the deformable portion 202 in the vertical direction. In this configuration, the portion between the two notches 207 is pressed outward and deformed so as to protrude into a substantially square shape when viewed from the front. In addition, the deformation part 202 may be a structure such as a protrusion formed so as to bulge outwardly by drawing.

  The outer connecting member 198 is formed so as to be more rigid than the inner connecting member 197. For example, the outer connecting member 198 is formed of a material such as a metal plate or a resin plate having a higher rigidity than the inner connecting member 197, or a material having the same rigidity as the inner connecting member 197 but a thicker material. It is formed with.

  The outer connecting member 198 has a concave shape as shown in FIGS. 19A and 19B in plan view, and includes a back portion 211 and left and right side portions 212. The left and right side portions 212 of the outer connecting member 198 are provided with the same number of notches 213 corresponding to the protrusions 205 of the inner connecting member 197. The notches 213 are provided at the same intervals as the protrusions 205 in the longitudinal direction (vertical direction) of the left and right side portions 212. The notch 213 is formed in a size that allows the protrusion 205 to be inserted.

  As will be described later in the description of the action, when the second wall panel 186 and the third wall panel 187 are connected, the protruding portion 205 of the inner connecting member 197 is formed inside the side portion 212 of the outer connecting member 198. Contact the wall.

(Assembly process)
A method for assembling the wall panel for assembling the wall panel of the bathroom unit having the above-described configuration will be described along the assembling process. First, the first wall panel 185 and the second wall panel 186 at the corners constituting the wall panel of the bathroom unit are orthogonal to each other on the floor 6 of the bathroom unit as in the first embodiment. And temporarily installing it in a temporarily connected state (see FIG. 1).

  Next, as shown in FIG. 22A, the second wall panel 186 and the third wall panel 187 are temporarily installed on the floor 4 such as a bathroom pan with the upright portions 188 facing each other. . Next, as shown in FIG. 20A, the outer connecting member 198 is fitted and overlapped on the back side of the inner connecting member 197, and the plurality of protrusions 25 of the inner connecting member 197 are respectively connected to the outer connecting member 198.

When the inner connecting member 197 is moved downward in this manner, the left and right protrusions 205 enter the inner wall surface side of the left and right side portions 212 of the outer connecting member 198 from the left and right cutout portions 213. Then, the left and right protrusions 205 act on the inner wall surfaces of the left and right side portions 212 of the outer connecting member 198 to exert a pressing force.

  However, since the outer connecting member 198 is more rigid than the inner connecting member 197, the outer connecting member 198 is not deformed even when a pressing force is applied by the projection 205, and the pressing force is applied to the inner connecting member 197. On the other hand, it acts as a reaction force toward the inner direction (right and left center direction). This reaction force acts inward with respect to the left and right deformed portions 202 of the inner connecting member 197 and deforms the left and right deformed portions 202 toward the left and right center sides that approach each other against the elasticity.

  Therefore, the inner connecting member 197 is deformed toward the inner side where the left and right deforming portions 202 approach each other, and the inner connecting member 197 moves downward in the outer connecting member 198 with the left and right projecting portions 205 contacting the inner wall surface of the outer connecting member 198.

The protruding portion 205 is in contact with the inner wall surface of the outer connecting member 198.

  In the state of FIG. 21A, the left and right protrusions 205 of the inner connecting member 197 are in contact with the inner wall surfaces of the left and right side portions 212 of the outer connecting member 198. As shown in FIGS. 21 (a), 21 (b), and 22 (b), the left and right deforming portions 202 of the inner connecting member 197 are pressed inward and maintained in a deformed state.

  As a result, as shown in FIG. 22B, the left and right wall contact portions 204 of the inner connecting member 197 are formed on the upright portion 188 of the second wall panel 186 and the upright portion 188 of the third wall panel 187, respectively. The two standing parts 188 are brought into contact with each other via the water-stopping packing 189 and brought into close contact with each other, and the second wall panel 186 and the third wall panel 187 are moved to an arrow X in FIG. Connect as shown in

  As described above, in the method for assembling the wall panel in the sixth embodiment, the inner connecting member 197 has the left and right deformed portions 202 deformed inward by the outer connecting member 198 via the left and right projecting portions 205, and the left and right wall contacts. The upright portion 188 of the second wall panel 186 and the upright portion 188 of the third wall panel 187 are urged and sandwiched by the contact portion 204 from the left and right sides, and are in close contact with each other via the water blocking packing 189.

  Therefore, in this method of assembling a bathroom wall panel, a simple water-stopping packing 189 is provided as an upright portion as shown in FIGS. 22 (a) and 22 (b) without providing a wall molding as in the prior art. Only by attaching to 188, the water stop effect is produced, and since the gap between the rising portion 188 of the second wall panel 186 and the rising portion 188 of the third wall panel 187 is small and inconspicuous, it is naturally connected. As a result, the design is improved.

  The inner connecting member 197 is provided with a plurality of protrusions 205, the outer connecting member 198 is provided with a plurality of notches 213, and the protrusions 205 can be fitted into the notches 213. The outer connecting members 198 do not slide relative to each other at a stroke, and the inner connecting members 197 can be gradually inserted into the outer connecting members 198 by hitting with a gavel or the like.
