Description

  The present invention relates to a connection structure for wall panels in a bathroom.

  As a connection structure of a wall panel constituting a wall of a bathroom composed of a conventional unit bathroom, for example, a structure shown in Patent Document 1 is known. This unit forms a flat mounting portion along the outer edge constituting one side of the bathroom floor, and a joiner receiving member is attached to a rising piece raised from the outer edge of the mounting portion of the bathroom floor, and is formed in a column shape on the front side. An open joiner with a substantially U-shaped cross section is erected on the joiner receiving member, the side piece protrudes backward from the side edge of the surface panel of the wall panel, and the rear end of the side piece is folded back to engage. In the storage groove formed between the side walls of the joiner having a substantially U-shaped cross-section on the side pieces of the respective face plates of the wall panels on both sides that are erected on the mounting part so as to sandwich the joiner In addition, the locking portion of each wall panel is locked to the locked portion formed inside the front end portion of each side wall of the joiner, and the gasket is placed between the side pieces of both wall panels stored in the joiner. I am typing.

  By the way, for example, in a bathroom floor provided with a bathtub portion 56 and a washing section, the outer edge on the bathtub section 56 side is set to the same height as the flange portion at the upper end of the bathtub section 56 as shown in FIG. In this case, it is one step higher than the lower placement part that is continuous to the lower placement part through the step surface along the lower edge of the washing section along the outer edge constituting one side of the bathroom floor. The upper mounting part 4 on the bathtub part 56 side is formed, the lower side wall panel 8 is erected on the lower mounting part, and the upper side wall panel 9 having a shorter vertical length than the lower side wall panel 8 is erected on the upper mounting part 4. Established.

  In order to connect the lower wall panel 8 and the upper wall panel 9, a right joiner receiving member 54a shown in FIG. 17 (a) or a left joiner receiving member 54b shown in FIG. 17 (b) has been conventionally used. The joiner receiving members 54a and 54b have a hooking piece 55 at the rear end. The hook piece 55 is attached by being hooked to a rising piece raised from the outer edge of the upper mounting portion 4 of the bathroom floor. Insertion portions 57 are formed on the upper surfaces of the joiner receiving members 54a and 54b, and a joiner 7 similar to the joiner shown in Patent Document 1 is joined to the joiner receiving member 54a, with the lower end portion fitted into the insertion portion 57. 54b. The side walls 28 (see FIG. 12) of the lower wall panel 8 erected on the lower mounting part and the upper wall panel 9 erected on the upper mounting part 4 are formed on both side walls of the joiner 7 having a substantially U-shaped cross section. 23, and the locking portions 39 of the wall panels 8 and 9 are respectively locked to the locked portions 25 formed inside the front end portions of the side walls 23 of the joiner 7. The lower wall panel 8 and the upper wall panel 9 are connected by driving a gasket between the side pieces 28 housed in the joiner 7 of each wall panel 8, 9.

  Here, for example, wall panels 8 and 9 as shown in FIG. 12 are used as the wall panels 8 and 9 that are erected on the lower mounting portion and the upper mounting portion 4 of the bathroom floor. The wall panels 8 and 9 are formed by bending the side edges and lower edges of the surface plate 26 rearward to form side pieces 28 and bottom pieces 30, and the side pieces 28 and bottom pieces 30 are continuously integrated. A wall portion that is folded back on the inside to form a locking portion 39 positioned above the bottom piece 30 and that has a space 40 that opens rearward between the bottom piece 30 and the locking portion 39 is provided. 8 and 9, since the bottom piece 30 and the side piece 28 placed on the placement part continuously form a corner, water leaks from between the side piece 28 and the bottom piece 30. There is an advantage that it can be prevented.

  The void 40 formed between the bottom piece 30 and the locking portion 39 of the surface plate 26 is formed for the following reason. That is, the wall panels 8 and 9 are manufactured, for example, by cutting out the outer edge portion of the corner portion of the rectangular flat plate-shaped metal plate constituting the surface plate 26, and bending the side portions sandwiching the notch of the metal plate to engage the locking portion. A side piece 28 and a bottom piece 30 with 39 are formed, and thereafter, a drawing jig is inserted from the rear into a space opened rearward between the engaging portion 39 of the surface plate 26 and the bottom piece 30. Then, the jig is positioned on the inner surface side of the unbent portion that is the portion of the side piece 28 and the bottom piece 30 that is left unbent, and thereafter the outer surface of the unbent portion is pressed with a roller or the like to leave the bend. 15 is bent along the outer surface of the jig and drawn, and as shown in FIG. 15, the side piece 28 and the bottom piece 30 are integrally continuous through the corners between them. 40 is for drawing a corner portion between the side piece 28 with the locking portion 39 and the bottom piece 30. It is for inserting a jig.

  However, since the wall panels 8 and 9 do not have the engaging portion 39 formed at the lower end portion of the side piece 28, the strength of the same portion is weak. Therefore, when such wall panels 8 and 9 are used as the upper side wall panel 9 erected on the upper mounting portion 4, the lower end of the side wall 28 of the upper side wall panel 9 that does not form the locking portion 39. When a gasket is driven between the side portion 28 and the side piece 28 of the lower side wall panel 8, there is a possibility that the lower end portion of the side piece 28 where the locking portion 39 is not formed is deformed. For this reason, conventionally, as shown in FIG. 17, a reinforcing portion 58 is projected on one half of the surface of the joiner receiving members 54 a and 54 b (half on the side of the upper wall panel 9). The lower end of the side wall 28 of the upper side wall panel 9 that does not form the locking portion 39 is aligned with the lower end of the side wall 28 of the upper side wall panel 9 so that the lower end of the side wall 28 of the upper side wall panel 9 does not form the locking portion 39. It is prevented from being deformed by driving. A groove 59 is formed in the other half of the joiner receiving members 54a and 54b (that is, the half on the lower wall panel 8 side), and the side piece 28 of the lower wall panel 8 and the latching are formed in the groove 59. The part 39 is accommodated.

By the way, the joiner receiving members 54a and 54b shown in FIG. 17 (a) have a reinforcing portion 58 in the right half and a groove 59 in the left half, that is, the upper side wall panel 9 is located on the right side. The lower wall panel 8 is located on the left side. On the contrary, when the upper side wall panel 9 is positioned on the left side, the engaging part 39 of the lower side wall panel 8 hits the reinforcing part 58 of the joiner receiving member 54a, so that the joiner receiving member 54a cannot be used. For this reason, conventionally, as described above, the reinforcing portion 58 is formed in the right half portion and the joiner receiving member 54a used when the upper side wall panel 9 is positioned on the right side, and the reinforcing portion 58 is formed in the left half portion. Two types of joiner receiving members 54b used when the upper side wall panel 9 is located on the left side are prepared and used, but in this case, the joiner receiving members 54a and 54b cannot be used together. The problem of high manufacturing costs arises.

The cuttable part 22 is formed thinner than the other part on the tip side.

  As shown in FIG. 10, the joiner 7 has a columnar shape and is formed in a substantially U-shaped cross section that opens forward by bending a metal plate, and a storage groove 24 is formed between both side walls 23. A locked portion 25 is formed over the entire length of the front edge of each side wall 23 of the joiner 7. As shown in FIG. 3, the locked portion 25 is formed by folding the front edge of each side wall 23 of the joiner 7 inside, and after the front edge of each side wall 23 is bent inward at a right angle. It is formed in a triangular shape in plan view by being bent toward the rear and obliquely rearward.

  In the lower wall panel 8 and the upper wall panel 9, the vertical dimension of the upper wall panel 9 is shorter than the vertical dimension of the lower wall panel 8 by the height dimension of the step surface 3. When standing, the upper end of the lower side wall panel 8 and the upper end of the upper side wall panel 9 are positioned at the same level.

  Although the lower side wall panel 8 and the upper side wall panel 9 have different vertical dimensions, other configurations have the same configuration. Each of the wall panels 8 and 9 includes a metal surface plate 26 and a heat insulating material 27 attached to the rear surface of the surface plate 26. Both side edges, upper edge, and lower edge of the surface plate 26 are bent rearward, thereby forming a side piece 28, an upper face piece 29, and a bottom piece 30, respectively. The upper surface piece 29 is formed in a portion excluding both end portions of the upper edge of the surface plate 26, and an opening portion 31 opening upward is formed between the upper surface piece 29 and each side piece 28. Each side piece 28 is formed over the entire length of the side edge of the surface plate 26, the bottom piece 30 is formed over the entire length of the lower edge of the surface plate 26, and each side piece 28 and the bottom piece 30 are connected via the corner portion. It is continuously integrated.

  The rear edge of the bottom piece 30 is bent vertically upward to form an attachment piece 32, and the attachment piece 32 is formed at a portion of the bottom piece 30 excluding both left and right ends. As shown in FIG. 13, a dart hole 33 is formed at an appropriate position of the mounting piece 32 to be used for mounting a hook 36 to be described later. The daruma hole 33 has a large hole 34 with a large vertical width on one side and a small hole 35 with a small vertical width on the other side.

  As shown in FIG. 6, the hooking tool 36 can be hooked on the upright piece 5 at the rear portion, and protrudes a protrusion 38 from the front surface. The vertical width of the protrusion 38 increases as it goes forward from the rear end, and the vertical width of the front end is larger than the vertical width of the small hole portion 35 of the saddle hole 33 and smaller than the vertical width of the large hole portion 34. Accordingly, the projection 38 of the hook 36 is passed from the rear of the mounting piece 32 through the large hole 34 of the daruma 33 and is positioned in front of the mounting piece 32. In this state, the hooking tool 36 is slid sideways. The hook 36 is attached along the attachment piece 32 by positioning the protrusion 38 in the small-width hole portion 35 and holding it at the hole edge. Note that the upper end portion of the hooking tool 36 protrudes forward, and the tip of the protruding portion abuts against the rear surface of the surface plate 26.

  Further, as shown in FIG. 12, the rear edge of each side piece 28 is folded back inside, thereby forming a locking portion 39 positioned above the bottom piece 30, and between the bottom piece 30 and the locking portion 39. A void 40 is formed in the opening. The engaging portion 39 in the illustrated example is formed in a triangular shape by bending the rear edge of the side piece 28 toward the inner diagonal front and then bending the front edge toward the outer diagonal front. Here, the void 40 opening rearward is formed between the bottom piece 30 and the locking part 39 as described in the background art section. The corner between the side piece 28 and the bottom piece 30 is formed in the void 40. This is because a jig for drawing the portion is inserted.

  Further, the gasket 10 driven between the lower wall panel 8 and the upper wall panel 9 forms a plurality of elastic fin pieces 41 (see FIG. 3) on both side surfaces toward the front side. The vertical dimension of the gasket 10 is substantially the same as the vertical dimension of the side piece 28 of the upper side wall panel 9.

  When the lower wall panel 8 and the upper wall panel 9 are built in the bathroom, for example, the rear part of the hook 36 attached to the upper wall panel 9 is first pulled from above to the rising piece 5 raised from the upper mounting part 4. As shown in FIG. 1, the bottom wall 30 of the upper side wall panel 9 is placed on the upper surface of the upper placement part 4 via the packing material 42 as shown in FIG. The engaging portion 39 formed on the side piece 28 of the upper side wall panel 9 is engaged with a corner joiner (not shown) erected on the corner portion of the bathroom floor 1, and the upper side wall panel is placed on the upper placement portion 4 as shown in FIG. 9 is erected.

  Next, the backup material 43 is attached over the substantially entire length in the vertical direction along the rear portion of the vertical step surface 3 raised from the lower mounting portion 2. The backup material 43 is a packing material 42 that is easily deformed with a member such as a sponge and has a sealing property, and the adhesive side surface exposed by peeling the tape of the backup material 43 is attached to the step surface 3. The lower surface is in contact with the lower mounting portion 2 and the lower end portion of the rear surface is attached to the step surface 3 in a state along the front surface of the rising piece 5 raised from the upper mounting portion 4.

  Next, a sealing material 44 is applied in the shape of a bowl in the vicinity of the attachment portion of the joiner receiving member 6, and then the mounting recess 17 of the joiner receiving member 6 is placed under the rising piece 5 raised from the outer edge of the upper mounting portion 4. The joiner receiving member 6 is attached to the upright piece 5 so that the sealant 44 seals between the joiner receiving member 6 and an adjacent member. In the joiner receiving member 6 attached in this way, as shown in FIG. 2, the other side where the reinforcing portions 19 and 20 are not provided protrudes toward the lower mounting portion 2 and the reinforcing portions 19 and 20 are provided. The side is located on the upper mounting portion 4. As shown in FIG. 1, one of the reinforcement portions 19 and 20 of the joiner receiving member 6 protrudes forward, and the side piece 28 of the upper side wall panel 9 is locked along the side surface of the reinforcement portion 19. The inner surface of the lower end portion where the portion 39 is not formed abuts, and the rear surface of the side end portion of the surface plate 26 of the upper side wall panel 9 abuts along the front surface of the reinforcing portion 19. Further, in this example, the lower end of the engaging portion 39 is further placed on the upper surface of the reinforcing portion 19, and the inner side surface of the lower end portion where the engaging portion 39 of the side piece 28 is not formed is also applied to the side surface of the base portion 18. Touch.

  Thereafter, as shown in FIG. 3, each side wall 23 of the joiner 7 is fitted into each side wall fitting groove 14 of the joiner receiving member 6, and the fitting portion 15 of the joiner receiving member 6 is fitted into the lower end portion of the joiner 7. The side piece 28 of the upper side wall panel 9 is inserted into the storage groove 24 of the No. 7, and the locking portion 39 formed on the side piece 28 is locked to the locked portion 25 on the upper mounting portion 4 side of the joiner 7. Thus, the joiner 7 is erected on the upper surface of the joiner receiving member 6. Here, the outer side surface of each side wall fitting groove 14 of the joiner receiving member 6 is an inclined surface that is inclined so as to be positioned on the outer side, and the front and rear edges and the corners of both side edges of the fitting portion 15 are chamfered. Thus, the fitting portion 15 is easily fitted into the lower end portion of the joiner 7.

  Next, the insertion portion 46 and the skirt portion 47 projecting downward from the right connection piece 45 shown in FIG. 10 are connected to the half portion on the upper mounting portion 4 side in the upper end portion of the joiner receiving member 6 and the opening portion 31 of the upper side wall panel 9. The right connection piece 45 covers the half part on the upper mounting portion 4 side of the joiner 7 and the opening 31 of the upper side wall panel 9 from above. Here, the insertion portion 46 of the right connection piece 45 is fitted between the joiner 7 and the locking portion 39 of the upper side wall panel 9, whereby the locked portion 25 of the locking portion 39 of the upper side wall panel 9. The locking to is more secure.

  Next, as shown in FIG. 6, the lower wall panel 8 is hooked on the rising piece 5 raised from the lower mounting portion 2 similarly to the upper wall panel 9 and the bottom piece 30 of the lower wall panel 8 is lowered. In a state where it is placed on the upper surface of the placement part 2 via the packing material 42, the lower wall panel 8 is pushed backward, and the side piece 28 on the upper placement part 4 side of the lower wall panel 8 is joined to the joiner 7 as shown in FIG.
