Description

  The present invention relates to a bathroom and a wall structure of a washroom formed by integrating a bathroom and an inner wall of a washroom adjacent to the bathroom.

  Residential bathrooms and washrooms are formed as standardized unit rooms, and the inner walls are formed by wall panels.

  Conventionally, a wall panel having a vertically long shape that reaches from the floor to the ceiling surface is used, and a plurality of the vertically long wall panels are juxtaposed side by side along the entire side of a room such as a bathroom or a washroom. The inner wall is formed by joining and standing between them.

  However, since the height of the room differs depending on the property, the vertically long wall panel must be produced for each property and cannot be kept in stock. In addition, it was necessary to reinforce in order to prevent vertical deflection, etc., and the vertical wall panel had to be specified and produced at an early stage in order to keep up with the construction. . For this reason, the room size was in line with the initial plan and could not be changed.

In order to eliminate the above inconveniences, a horizontally long wall panel whose width is substantially equal to the length of each side of the room is used, and a joint material is erected at the corner of the room, and the horizontally long wall is formed on the joint material. There has been proposed a wall structure in which panels are joined to each other and the wall panels are connected to each other at right angles, and horizontally long wall panels are stacked from the bottom to form an inner wall (Patent Documents 1 and 2).

Such a support leg portion 19 can be formed by bending a single metal plate, so that the decorative plate 7 does not interfere with the flange portion 17 when the wall panel 5a is placed on the flange portion 17. The lower end of the part 19b protrudes slightly downward from the lower edge of the decorative board 7.

  By attaching the hook 18 and the support leg 19 to the lower end portion of the wall panel 5a, the flange portion 17 is placed between the decorative plate 7 and the hook 18 when the wall panel 5a is placed on the flange portion 17 of the floor pan F1. The rising portion 17b rising from the outer edge of the horizontal surface portion 17a can be inserted, and the hook 18 can hold the rising portion 17b by elasticity, and the wall panel 5a is positioned and can be easily built. Further, since the wall panel 5a is placed on the horizontal surface portion 17a of the flange portion 17 in the placement portion 19c of the support leg portion 19, it does not interfere with the decorative board 7 and is stable to the flange portion 17. It can be placed on top.

  The hook 18 and the support leg 19 may be provided over the entire length of the lower frame 8b, or may be provided partially with a certain interval.

  The wall panel 5a placed on the flange portion 17 of the floor pan F1 and attached with the joint material 13 in this way is once arranged outside the inner wall W1 shown in FIG. The wall panel 5a on the inner wall W2 side is built by being held by W. That is, as shown in FIG. 7 <a>, the wall panel 5a on the inner wall W2 side has a lower end portion on the flange portion 17 orthogonal to the flange portion 17 of the floor pan F1 on which the wall panel 5a on the inner wall W1 side is placed. Is inserted into the flange portion 17 of the floor pan F1 as described above. Thereafter, the wall panel 5a on the inner wall W1 side is raised, and the joint member 13 is superposed on the left frame 8c of the frame frame 8 of the wall panel 5a on the inner wall W2 side on the coupling surface portion 13b side. At this time, the joint material 13 is located at a corner portion between the inner wall W1 and the inner wall W2 of the bathroom 1, and the dowel 16 protruding from the coupling surface portion 13b is provided on the outer surface 10 of the left frame 8c of the wall panel 5a on the inner wall W2 side. The joint hole 12 is formed in the circular hole portion 12a.

  In this state, as shown in FIG. 7 <b>, the joint material 13 is struck down on the upper end surface thereof using the plastic hammer 21. Then, the dowel 16 on the joint surface portion 13a side of the joint material 13 is fitted into the vertical hole portion 12d of the joint hole 12 formed on the outer surface 10 of the right frame 8d of the wall panel 5a on the inner wall W1 side, and the joint surface portion 13b side. Of the inner wall W2 side wall panel 5a and the left side frame 8c of the left frame 8c is fitted into the longitudinally long hole portion 12b of the joint hole 12, and the two wall panels 5a on the inner wall W1, W2 side are joined. It couple | bonds with the material 13, and the lower surface of the connection part 13c of the joint material 13 lands on the horizontal surface part 17a of the flange part 17 of the floor pan F1.

  As shown in FIG. 9, the two wall panels 5 a on the inner walls W <b> 1 and W <b> 2 side are connected at right angles via a joint material 13 erected at the corner portion of the bathroom 1. The sealing material 22 is filled between the adjacent edge portions of the two wall panels 5a, so that the edge portions can be made inconspicuous.

  Next, the wall panel 5a forming the inner wall W3 shown in FIG. 1 is built. As shown in FIG. 10, the wall panel 5 a on the inner wall W <b> 3 side is connected to the wall panel 5 a on the inner wall W <b> 2 side at a right angle using the joint material 13. In this case, the joint material 13 is formed on the left frame 8c of the frame frame 8 of the wall panel 5a on the inner wall W3 side, and the dowels 16 protruding from the coupling surface portion 13b of the joint material 13 are formed on the outer surface 10 of the left frame 8c. The wall panel 5a on the inner wall W3 side is inserted into the flange portion 17 of the floor pan F1 by a hook 18 and placed, and the joint material 13 is disposed at the corner portion of the bathroom 1. Next, the joint surface 13a of the joint member 13 attached to the left frame 8c of the wall panel 5a on the inner wall W3 side is placed on the outer surface 10 of the right frame 8d of the frame frame 8 of the wall panel 5a on the inner wall W2 side, and the dowel 16 is placed on the right frame. It inserts into the oval hole part 12c of the joint hole 12 formed in the outer surface 10d of 8d, and is superposed | polymerized. Then, the joint material 13 is struck down on the upper end surface using the plastic hammer 21. The dowels 16 are fitted into the vertically long holes 12b and 12d of the joint hole 12, respectively, and the lower end of the connecting portion 13c is landed on the flange 17 of the floor pan F1. A joint member 13 is erected at a corner portion between the inner walls W2 and W3 of the bathroom 1, and the wall panel 5a on the inner wall W3 side is connected to the wall panel 5a on the inner wall W2 side at a right angle. In this way, the lower wall panels 5a in the three inner walls W1, W2, and W3 except for the entrance 3 of the bathroom 1 are built.

  As shown in FIG. 11, the middle wall panel 5b is built after the lower wall panel 5a has been built. Since the constructed lower wall panel 5a is connected in a U shape and the built-in state is stable, the middle wall panel 5b can be easily constructed.

  When the middle wall panel 5b is built, the joint material 13A having a length substantially equal to the vertical width of the wall panel 5b is connected to the lower end connection portion 13c, and the joint material 13 to which the lower wall panel 5a is coupled. As shown in FIG. 8 and FIG. 9, the two coupling surface portions 13 a and 13 b that are orthogonal to each other are inserted and connected on the joint material 13.

  The connection between the joint material 13A and the joint material 13 is performed simultaneously with the erection of the wall panel 5b, that is, the stacking of the wall panel 5b on the wall panel 5a and the connection of the wall panel 5b to the joint material 13A.

  First, the joint material 13A is inserted into the joint material 13 erected at the corner portion between the inner wall W1 and the inner wall W2, and the connection portion 13c is partially inserted into the upper end portion of the joint material 13 to be temporarily connected. Next, the lower end is overlapped with the upper end of the wall panel 5a and the wall panel 5b is arranged on the wall panel 5a. Then, the wall panel 5b is slid in the lateral width direction on the wall panel 5a, and the joint surface 13a of the joint material 13A The dowels 16 projecting from the joint surface portion 13a of the joint material 13A are inserted into the oval hole portion 12c of the joint hole 12 formed in the outer surface 10 of the right frame 8d of the frame frame 8 of the wall panel 5b, Fit loosely to a temporary fit. Then, the joint material 13A is struck downward with a plastic hammer 21 at the upper end surface thereof. The connecting portion 13 c is completely inserted into the upper end portion of the joint material 13, and the joint material 13 </ b> A is permanently connected to the joint material 13. The connecting portion 13c of the joint material 13A is reliably inserted into the upper end portion of the joint material 13 by the edge portions 14 of the joint surface portions 13a and 13b of the joint material 13 that also serve as a stopper, as shown in FIG. Simultaneously with the main connection of the joint material 13A, the dowels 16 protruding from the coupling surface portion 13a of the joint material 13A are formed in the vertical holes of the joint holes 12 formed on the outer surface 10 of the right frame 8d of the frame frame 8 of the wall panel 5b. The wall panel 5b and the joint material 13A are coupled to each other, and the wall panel 5b is stacked and built on the wall panel 5a. Thereafter, the wall panels 5b on the inner walls W2 and W3 are built in the same manner.

  Thus, since the wall panel 5b is built while connecting the joint material 13A to the joint material 13 and can be stacked on the wall panel 5a, the construction of the wall panel 5b is easy, and the corner portion has high rigidity. Obtainable.

  As shown in FIG. 12, the band plate 23 is attached to the upper frame 8a of the frame frame 8 of the lower wall panel 5a so that the wall panel 5b can be stably stacked on the wall panel 5a when the wall panel 5b is stacked. And a sandwiching piece 24 is provided on the lower frame 8b of the frame 8 of the middle wall panel 5b.

  The band plate 23 is a horizontally long metal member having a width substantially equal to the width of the wall panel 5a, and is provided over the entire length of the upper frame 8a. The band plate 23 is in contact with the back surface of the upper frame 8 a and is fixed by a fixing tool such as a screw 25. The upper end portion of the band plate 23 projects upward from the upper end of the wall panel 5a, and the upper end edge is slightly higher than the upper end surface of the lower frame 8b of the wall panel 5b when the middle wall panel 5b is stacked on the lower wall panel 5a. It is arranged below. A lower end portion of the band plate 23 is bent at a substantially right angle, and an extending portion 23a is formed toward the rear side of the rear surface of the wall panel 5a. The extending portion 23 a increases the strength of the band plate 23.

  The sandwiching pieces 24 are metal members, and a plurality of the sandwiching pieces 24 are arranged at regular intervals in the lateral width direction of the wall panel 5b. The clamping piece 24 has a mounting portion 24a and a clamping portion 24b that is bent substantially vertically from one end of the mounting portion 24a and extends near the lower end of the wall panel 5b. The sandwiching portion 24b is bent obliquely toward the rear side of the back surface of the wall panel 5b at a substantially central portion. The clamping piece 24 abuts the mounting portion 24a on the upper end surface of the lower frame 8b of the wall panel 5b, is overlapped, and is fixed by a fixing tool such as a dowel 26. In the fixed state, the sandwiching portion 24b of the sandwiching piece 24 is disposed away from the back surface of the lower frame 8b by the approximate thickness of the band plate 23.

  When the wall panel 5b is stacked on the wall panel 5a, the upper end portion of the band plate 23 is inserted between the lower frame 8b of the wall panel 5b and the holding piece 24 fixed to the lower frame 8b. Since the sandwiching portion 24b of the sandwiching piece 24 is bent obliquely toward the rear side of the back surface of the wall panel 5b at a substantially central portion, the insertion of the band plate 23 is easy, and the elasticity of the sandwiching portion 24b is the thickness of the wall panel 5b. In order to act in the direction, the clamping part 24b clamps the belt plate 23 between the lower frame 8b. Therefore, the wall panel 5b is stably disposed on the wall panel 5a, and when built, the wall panel 5b can be slid laterally on the wall panel 5a to approach the joint member 13A. Construction of the wall panel 5b is easier. Moreover, when the clamping piece 24 clamps the strip 23, the strip 23 functions as a reinforcing material for the wall panels 5a and 5b, and the surface strength is increased.

  The band plate 23 and the sandwiching piece 24 can be disposed at the upper end portion of the lower wall panel for the band plate 23 and at the lower end portion of the upper wall panel for the sandwiching piece 24. That is, the band plate 23 is attached to the upper frame 8a of the frame frame 8 in the same manner as described above on the middle wall panel 5b, and the upper wall panel 5c shown in FIG. 4 is stacked on the middle wall panel 5b. The clamping piece 24 is attached to the lower frame 8b of the frame 8 as described above.

  After the middle wall panel 5b is built in the bathroom 1, as shown in FIG. 13, the inner wall of the washroom 2 is attached to each joint member 13 located on the left and right sides of the entrance 3 between the bathroom 1 and the washroom 2. The joint material 27 used for construction is connected and erected on the floor F. Similar to the joint members 13 and 13A, three types of joint members 27 having a length substantially equal to the vertical width of the lower, middle and upper wall panels 5a, 5b and 5c are prepared. Each joint material 27 has the same structure, and has two coupling surface portions 27a and 27b that are orthogonal to each other, as in the joint materials 13 and 13A, and extends downward from the back surface side of the coupling surface portions 27a and 27b at the lower end portion. Department. Dowels project from the coupling surface portions 27a and 27b as fitting portions.

  When connecting the joint material 27 to the joint material 13, the coupling surface portion 27a of the joint material 27 is overlapped with the coupling surface portion 13b of the joint material 13, and the coupling surface portion 27b is disposed so as to face the coupling surface portion 13a. At this time, the dowels of the coupling surface portion 27a and the coupling surface portion 13b to be overlapped are removed. Then, the joint material 27 is connected to the joint material 13 using a fastener such as a screw 28. Since the connecting surface portion 27a and the connecting surface portion 13b are formed with holes for attaching dowels, it is easy to connect with a fixing tool such as a screw 28. Further, prior to the connection of the joint material 27, the connection of the joint material 13A is performed so that the wall panels 5a and 5b built on the inner walls W1 and W3 are not bent and the connection work can be performed stably. A horizontal member 29 is installed between the wall panels 5b using the dowels 16 protruding from the upper end of the surface portion 13b.

  After the joint material 27 is connected, the upper wall panel 5c is built in the bathroom 1 in the same manner as the construction of the wall panel 5b to complete the inner walls W1, W2, and W3.
