The member shown in FIG. 3A is substantially the same as the member shown in FIG.

  In the fixing structure of the present invention, the ceiling panel 40 is placed on the upper ends of the left and right and front and rear wall panels 30 and 30 that are attached to the plurality of posts 10 and face each other, and the top portions (upper end sides) of the plurality of posts 10 are connected to each other. Thus, the left and right and front and rear edges of the ceiling panel 40 are in contact with the connecting members 20 and 20 on both the left and right and front and rear sides facing each other. In the fixing structure of the present invention, a connecting member 50 that protrudes downward is attached to each side edge of the ceiling panel 40 on both the left and right and front and rear sides, and each connecting member 50 is connected to the gap S (between the wall panel 30 and the connecting member 20. 4) and is in contact with the rear surface side (outdoor O side) of the wall panel 30, and the pressing force when the wall panel 30 is pressed from the panel surface side (indoor I side) is applied to the ceiling panel 40. Communicating. In the above description, the example in which the connecting members are provided on the left and right and front and rear sides has been described. However, the connection member may be provided only on the left and right sides or only on the front and rear sides. It is also possible to replace it with “both sides” or “both sides”. The fixing structure of the present invention is applied to a unit room such as a bathroom in this example.

  As shown in FIG. 3A, the plurality of posts 10 are erected on the periphery of a rectangular waterproof pan 1 installed below the unit room. The post 10 includes a corner post 11 standing at a corner of the waterproof pan 1 and an intermediate post 12 standing between the corner posts 11. In this example, the corner post 10 is made of lip angle steel, and as shown in FIG. 3A, the slit 11a extending over the entire length is arranged so as to face the room I side. The intermediate post 12 is made of a lip groove steel in this example, and is arranged so that the slit 12a extending over the entire length is directed toward the room I side.

  In this example, the connecting member 20 is formed of channel steel including a web plate 20a and a flange 20b. As shown in FIG. 3 (A), the connecting member 20 has both side edges of the web plate 20a connected to the top of the side surface 11b of the corner post 11 on the outdoor O side by screws or the like, and the center of the web plate 20a. The part is connected to the top of the side surface 12b on the outdoor O side of the intermediate post 12 with screws or the like, and is arranged on the four sides on the ceiling side of the unit room.

  As shown in FIG. 1, the wall panel 30 includes a rectangular steel plate 31 disposed on the room I side, and a backing material 32 made of gypsum board or the like provided on the back surface of the steel plate 31. The steel plate 31 includes a main plate portion 31a, a bent portion 31b projecting perpendicularly from both sides of the main plate portion 31a to the back side as shown in FIG. 3B, and a main plate portion 31a as shown in FIG. It consists of a bent portion 31c that protrudes at a right angle from the upper side to the back surface side, and a bent portion 31d that protrudes at a right angle downward from the bent portion 31c. The wall panel 30 is attached between the posts 10 by engaging and engaging the bent portions 31b at both side edges thereof with the slits 11a of the corner posts 11 and the slits 12a of the intermediate posts. Go around the sides. Since the wall panel 30 is disposed on the room I side away from the connecting material 20, a gap S (see FIG. 4) having an upper opening is formed between the wall panel 30 and the connecting material 20. In the fixing structure of the present invention, the wall panel fixing bracket 150 (see FIG. 3B) described in the conventional example is provided between the wall panel 30 and the connecting member 20 at an appropriate location, and the wall panel 30 is installed indoors. The wall panel 30 is prevented from being bent and deformed when pulled to the I side.

  As shown in FIG. 1, the ceiling panel 40 includes a rectangular steel plate 41 disposed on the room I side and a backing material 42 made of a gypsum board or the like provided on the back surface of the steel plate 41. The steel plate 41 includes a main plate portion 41a and a bent portion 41b that protrudes perpendicularly from the edge of the main plate portion 41a to the back surface side. In the ceiling panel 40, screw insertion holes (not shown) for attaching the connecting member 50 are formed at appropriate positions on the edge side of the main plate portion 41a. As shown in FIG. 3B, the ceiling panel 40 of this example is composed of two panels, a divided panel 43 and a divided panel 44 in which an inspection port 44b is formed. The side edge 43a of the divided panel 43 and the side edge 44a of the divided panel 44 are connected by screws or the like. In addition to the above, the ceiling panel 40 may be constituted by a single panel in which an inspection opening is formed, although illustration is omitted.

As shown in FIG. 2, the connecting member 50 includes a horizontal plate portion 55, a mounting portion 51 including a connecting member abutting portion 53 protruding vertically upward from one end portion 55 a of the horizontal plate portion 55, and the horizontal plate. A wall panel abutting portion 52 projecting vertically downward from the other end 55 b of the portion 55, and an engaging portion 54 projecting one side and upward from the lower end of the wall panel abutting portion 52. In this example, the connecting member 50 is composed of a plurality of short piece pieces attached to the side edges of the ceiling panel 40 at appropriate intervals as shown in FIG. There is also an aspect (not shown). The connecting member 50 of this example is made of metal or resin having high rigidity and easy to process.

  The connecting member 50 is formed with a screwing hole 55c (see FIG. 2) in the center of the horizontal plate portion 55. A screw 45 (tapping screw) inserted into the screw insertion hole of the ceiling panel 40 is screwed into the screwing hole 55c, so that the upper surface of the horizontal plate portion 55 and the bottom surface of the ceiling panel 40 come into contact with each other. The connecting member 50 and the ceiling panel 40 are connected in a state. Although not shown in the drawings other than the connection structure using the screw 45, a structure in which an engagement portion is provided between the attachment portion 51 and the ceiling panel 40 to be connected may be employed. In the present invention, since the connecting member 50 is connected to the ceiling panel 40 with the screw 45, first, the connecting member 50 is not attached to the ceiling panel 40, and is then carried into the assembly site, and then at the assembly site. Since an assembling method for attaching the connecting member 50 can be adopted, the carrying-in is easy. Of course, the ceiling panel 40 can be carried into the site with the connecting member 50 attached in advance.

As shown in FIG. 1, when the attachment portion 51 is attached in advance to the side edge of the ceiling panel 40 with screws 45 and is placed in the gap S, the connecting member 50 has the wall panel abutment portion 52 in the gap. S is located near the interior I of the wall S and abuts against the back side (outdoor O side) of the wall panel 30, and the connecting material abutting portion 53 abuts against the joining material 20 located near the exterior O of the gap S and engages. The part 54 engages with the tether 20.

  When the connecting member 50 is inserted and disposed in the gap S, the other side surface 52a of the wall panel contact portion 52 contacts the bent portion 31d above the wall panel 30, and one of the connecting material contact portions 53 The side surface 53 a abuts on the web plate 20 a of the connecting material 20.

The connecting member 50 is set so that when the fitting member 54 is fitted and arranged in the gap S, the one upper end 54 a of the engaging portion 54 comes into contact with the flange 20 b on the lower end side of the connecting member 20 from below. Lifting can be surely prevented. The engaging portion 54 is set such that its horizontal width (the distance in the horizontal direction from the one upper end 54a to the other lower end 54b) is longer than the horizontal width of the gap S. The connecting member 50 is formed from a metal or resin elastic material, and is appropriately elastically deformed when fitted into the gap S so that the horizontal width of the engaging portion 54 can be reduced. Further, the engaging portion 54 has a shape projecting upward in one direction, and is easily elastically deformed when the connecting member 50 is inserted into the gap S from above, and the connecting member 50 after the insertion is located above the gap S. It is difficult to pull out.

In the fixing structure of the present invention, for example, when the left wall panel 30 is pressed from the panel surface side (inside the room I) toward the left side in FIG. Since the left wall panel 30 is supported via the panel contact portion 52, the upper end side of the left wall panel 30 is not easily bent and deformed. In the fixing structure of the present invention, even if the left connecting member 20 is bent and deformed together with the upper end side of the left wall panel 30 by being pressed with a strong force under the above conditions, the ceiling panel 40 is also deformed by the bending deformation. Since the upper end side of the right wall panel 30 that moves to the left side and is pressed by the wall panel contact portion 52 of the right connecting member 50 is also bent and deformed to the left side by the same amount, the ceiling panel 40 and the left and right walls There is no misalignment with the panel 30. Therefore, the fixing structure of the present invention can reliably prevent the inner corner seal 60 provided between the ceiling panel 40 and the left and right wall panels 30 from being broken. In the above description, the example in which the left wall panel 30 indicated by the arrow in FIG. 1 is pressed from the room I has been given. Of course, the fixing structure of the present invention also includes the right, front, and rear wall panels 30 in the room. Even when pressing from the I side, it is possible to reliably prevent the seals 60 at the corresponding inner corners on both sides from being broken.

  In the fixing structure of the present invention, since the wall panel abutting portion 52 and the connecting material abutting portion 53 are provided on the connecting member 50, when the wall panel 30 is pressed from the panel surface side (the room I side). All the pressing force transmitted to the connecting material 20 passes through the connecting member 50. Therefore, the fixing structure of the present invention is weak in strength because the pressing force is not directly transmitted between the connecting material 20 and the ceiling panel 40 when the wall panel 30 is pressed from the panel surface side (the room I side). There is little risk of deforming the edge side (for example, the bent portion 41b) of the ceiling panel 40.

  In the fixing structure of the present invention, the distance from the other side surface 53b of the connecting member abutting portion 53 of the connecting member 50 to the screwing hole 55c of the horizontal plate portion 55, and the screw insertion from the bent portion 41b of the ceiling panel 40. The distance to the hole is substantially the same. Therefore, since the fixing structure of the present invention can be connected in a state where the other side surface 53b of the connecting material contact portion 53 and the bent portion 41b of the ceiling panel 40 are in contact with each other by screwing, the ceiling panel 40 and the connecting member 50 are connected. Since the transmission of the horizontal force between them is distributed in addition to the screw 45, it is also performed at the contact portion between the other side surface 53b of the connecting material contact portion 53 and the bent portion 41b of the ceiling panel 40. Thus, it is possible to prevent an excessive force from loosening the screw 45 from being applied to the screw 45.

  Further, in the fixing structure of the present invention, since the engaging portion 54 engages with the connecting member 20 and prevents upward pulling, the ceiling panel 40 can be reliably prevented from being lifted. Further, in the fixing structure of the present invention, since the engaging portion 54 is engaged only with the connecting member 20, the connecting member is compared with the case where the engaging portion 54 is engaged with both the connecting member 20 and the wall panel 30. 50 is easy to fit in the gap.

  In the fixing structure of the present invention, the horizontal width from the wall panel contact portion 52 to the connecting material contact portion 53 of the connecting member 50 is made substantially the same as or slightly larger than the horizontal width of the gap S, thereby In some cases, it is difficult to remove the ceiling panel 40 by fitting it into S. In this case, if the engaging portion 54 described above is omitted, the structure of the connecting member 50 can be simplified by the absence of the engaging portion 54, and the work of fitting the engaging portion 54 into the gap S can be omitted.

Of course, the shape, material, and the like of the connecting member 50 are not limited to the above-described modes, and there is a mode in which, for example, a quadrangular prism material such as resin or wood is employed. In this embodiment, one of the four side surfaces of the rectangular column member may be attached to the ceiling panel 40 and the side surface adjacent to the side surface may be brought into contact with the rear surface side of the wall panel 30.

The fixing structure of the present invention is assembled by the following steps (1) to (5).
(1) First step (preparation step): First, as described above, the connecting member 50 is attached to the ceiling panel 40 (divided panels 43 and 44) with screws 45, and the connecting member 50 protrudes below the ceiling panel 40. Put it in a state.

  (2) Second Step (Standing Step for Posts 10): Next, as described above, after the posts 10 are erected on the waterproof pan (see FIG. 3A), the tops of the posts 10 are connected to each other. Connect at 20.

  (3) Third step (wall panel 30 standing step): Subsequently, as described above, the bent portion 31b of the wall panel 30 is engaged and fitted into the slits 11a and 12a of the post 10 (FIG. 3B). )), The wall panel 30 is erected between the posts 10 and surrounds the four sides of the room.

  (4) Fourth step (step of fitting the ceiling panel 40): Subsequently, as shown in FIG. 4, first, one of the divided panels 43 and 44 constituting the ceiling panel is temporarily set in the room I. After lifting upward, the tool with a suction cup (not shown) is attached to this, and the tool with the suction cup is pulled from below, for example, and fitted into the connecting material 20 surrounding the four sides. At this time, the connection member 50 is elastically deformed by the one upper end 54a of the engagement portion 54 being slidably guided by the web plate 20a of the connecting member 20, and the connection member 50 being pushed toward the wall panel 30 (inside the room I). In the state, it is inserted into the surrounding gap S. When the insertion is advanced and the one upper end 54a of the engaging portion 54 is positioned below the web plate 20a of the connecting member 20, the elastic deformation is released and the original shape is restored. The upper end 54 a comes into contact with the flange 20 b on the lower end side of the connecting member 20 from below, and the horizontal width of the engaging portion 54 is longer than the horizontal width of the gap S. If the ceiling panel 40 is mounted in the bending part 31c of the upper end of the standing wall panel 30, fitting will be stopped. After that, after fitting the remaining one of the divided panels 43 and 44 in the same procedure, the body is placed on the back side of the divided panel 44 from the inspection port 44a, and the side edge 43a of the divided panel 43 and the divided panel 44 are The side edge 44a is connected.

  (5) Fifth step (sealing step): After connecting the divided panels 43 and 44, the inner corners of the four sides of the wall panel 30 and the ceiling panel 40 are finally sealed 60 with a caulking material or the like to complete the assembly. To do.

  In the fixing structure of the present invention, as shown in the above-described fourth step, each connection attached to both sides of the ceiling panel 40 in each of the gaps S on both sides formed between the wall panels 30 and the connecting member 20 on both sides. By inserting the member 50 from above, the edges of the ceiling panel 40 abut on the connecting members 20 on both sides, and the connecting member 50 abuts on the back side of the wall panels 30 on both sides, so that the wall panels 30 on both sides and Both sides of the ceiling panel 40 are connected to the connecting material 20. Further, as described above, both sides of the ceiling panel 40 can be connected to the wall panels 30 and the connecting material 20 on both sides by a simple operation (the above-described fourth step) in which the connecting members 50 are inserted into the gaps S on both sides from above. Thus, the screwing work at the back of the ceiling, which is a conventional work using the inspection port, is unnecessary, and the work of attaching the ceiling panel 40 can be facilitated. Further, the fixing structure of the present invention is low in cost because the inner corners of the wall panel 30 and the ceiling panel 40 are blinded by sealing with a caulking material or the like.

FIGS. 5A and 5B show a second embodiment of the fixing structure of the present invention, and FIGS. 5A and 5B are front sectional views in which main parts of different modes are enlarged. The fixing structure of the present embodiment of the present embodiment is different from the fixing structure of the first embodiment in that when the connecting member 70 is disposed in the gap S, it is not the connecting material 20 but the wall panel 30. It is in the point provided with the engaging part 71 to engage. Thereby, since the engaging part 71 engages with the wall panel 30 and prevents the upward pulling out, the fixing structure of the present invention can reliably prevent the ceiling panel 40 from being lifted.

As shown in FIGS. 5A and 5B, the connecting member 70 of the present example has a shape including an engaging portion 71 provided on the wall panel contact portion 52 and bulging to the other side. In this example, the upper end of the engaging portion 71 is in contact with the lower end of the bent portion 31 d of the wall panel 30. Since the engaging portion 71 has a shape having an inclined surface 71a inclined with respect to the insertion direction of the connecting member 70, the fixing structure of the present invention is bent in the middle of inserting the connecting member 70 into the gap S from above. Easy to deform.

As shown in FIG. 5A, an upper piece 91 that protrudes perpendicularly from the upper end of the connecting material contact portion 53 to the other, and a lower piece 92 that protrudes perpendicularly from the lower end of the wall panel contact portion 52 to one side. Even if provided, the upper piece and the lower piece may be omitted as shown in FIG.

As shown in FIG. 5A, the connecting member 70 of this example is of a type that is screwed with the screw 81 facing downward, and a type that is screwed with the screw 82 facing upward as shown in FIG. 5B. is there. In the former type, a screwing hole (not shown) is formed in the center of the horizontal plate portion 55, and a corresponding screw insertion hole (not shown) is formed in the ceiling panel 40. On the other hand, in the latter type, a screw insertion hole (not shown) is formed in the center of the horizontal plate portion 55, and a screwing hole (not shown) corresponding to this is formed in the ceiling panel 40.
