A pull-down piece protrudes from the part and forms a space between the protruding surface and the stepped surface, and a caulking material is interposed in the space.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, X denotes a unit room main body, which is formed by covering the upper end of a side wall panel B, which is circumferentially provided on a waterproof pan C via a joint member F, with a ceiling panel A via a rotating edge D.

The side wall panel B is formed by adhesively fixing a laying member 3B such as a tile 2B on the surface of the base 1B while leaving an upper area on the surface of the base 1B, so that the upper surface of the uppermost tile 2B becomes a stepped surface 2B', and the upper and lower ends of the back surface of the base 1B and It is formed by attaching and fixing the backing frame E to both ends of the back surface.

The backing frame E has approximately the same length as each side of the base 1B, is formed of a metal plate and has a cross-section with a slit 2E opened on the side surface over the entire length, and is formed of a metal plate at the upper end of the back surface of the side wall panel B. 1st backing frame 3E
is mounted and fixed with the slit 2E facing upward, and the second backing frame 4E at both ends of the side wall panel B is mounted and fixed with the slit 2E facing in a direction perpendicular to the base 1B.

The first backing frame 3E is a bent piece 1E that is inclined inward from the opening edge of the slit 2E near the back side of the base 1B and in a direction that narrows the slit 2E.
The second backing frame 4E is formed by bending the opening edge 4E' of the slit 2E, which is close to the adjacent side wall panel B side, and the second backing frame 4E is inwardly connected to the opening edge 4E' of the slit 2E.
A bent piece 1E that is inclined in the direction of narrowing E is formed by bending.

The circumferential edge D is an extrusion molded product made of synthetic resin such as PVC, and is cut to have approximately the same length as the four sides of the lower surface of the ceiling panel A, and includes a fitting groove 1D that fits and holds the circumferential edge of the ceiling panel A, and the fitting groove. A hollow frame portion 9D formed adjacent to 1D, a bottom portion 5D at the bottom of the fitting groove 1D, a space portion 6D, and an intermediate horizontal piece portion that has a locking piece portion 4D at one end and a hanging piece portion 3D at the other end. It consists of 7D.

The locking piece 4D is bent approximately vertically downward from one side end of the horizontal piece 7D, and the first backing frame 3 is attached to the tip thereof.
A hooking piece 8D that elastically engages with the tip of the bent piece 1E of E is bent.

The hanging piece 3D is formed to hang downward from the other end of the horizontal piece 7D, and has a horizontally projecting pull-down piece 2D integrally formed at its lower end.

The locking piece 4D and the hanging piece 3D are bent from both ends of the horizontal piece 7D so as to have a width slightly smaller than the width of the bent piece 1E and the surface of the side wall panel B. A fitting groove J for fitting the upper end of the side wall panel B is formed between the locking piece 4D and the hanging piece 3D.

In this way, the ceiling panel A with the rotating edge D attached to the peripheral end via the fitting groove 1D is positioned over the upper opening Y and is pulled down to close the upper opening of the unit room main body X. In this case, the pull-down piece 2
When D is pulled down using the tool 1, the hanging piece part 3D descends while slidingly contacting the inner surface of the side wall panel B as a guide, and at the same time, the locking piece part 4D is slightly elastically deformed by the bent piece 1E and expands as the hanging piece part. Following the movement of 3D, the hooking piece 8D descends and eventually engages the tip of the bent piece 1E to connect the ceiling panel A to the upper end of the side wall panel B. At this time, a space 200 is formed between the pull-down piece 2D and the stepped surface 2B', and the caulking material V is interposed within this space 200.

The caulking material V is a silicone-based resin that has adhesiveness and elasticity that hardens naturally when left in the air, and may be applied in advance before the ceiling panel A is closed.

In this state, even if the ceiling panel A is pushed upward, the hooking piece 8D is elastically engaged with the bending piece 1E, and is also bonded with caulking material, so it will not come off easily. There is no need to provide attachment means such as screwing the rotating edge D itself to the upper end of the rear side wall panel B of the ceiling panel A.

2 is a latch claw piece formed by bending the tip of the pull-down piece 2D downward; 3 is a latch tooth formed recessed between the horizontal piece part 7D and the bottom 5D of the fitting groove 1D on both upper and lower inner surfaces. A blinding material 5 is attached to the hooking groove in which the portion 4 is carved through the hooking claw piece 2 and the hooking groove 3.

The blindfold material 5 is a band-shaped covering plate portion 5 made of hard resin.
The lower end of a has an engaging claw piece 5b, and the upper end has a protruding strip 5d with engaging teeth 5c carved on the upper and lower surfaces, and elastic fin pieces 5 made of soft resin are formed on both upper and lower edges.
e is integrally formed.

This blindfold material 5 is attached to the boundary between the ceiling panel A and the side wall panel B by engaging the protrusion 5d with the engaging groove 3 and engaging the engaging claw piece 5b with the engaging claw piece 2 from the inside of the room. Installation, elastic fin piece 5
e is elastically brought into close contact with the lower surface of the ceiling panel A and the inner surface of the side wall panel B, and the rotating edge D and caulking material V are attached.
cover so that it cannot be seen from inside the room.

Thus, the joint portion between the ceiling panel A and the side wall panel B is completely sealed, and water and air leakage from this portion is completely prevented.

The joint member F includes a first joint member 1F that connects adjacent side wall panels B in a horizontal row, and a second joint member 1F that connects the side wall panels B forming the corner.
It has a joint member 2F. The first joint member 1F is connected to the second backing frame 4 on the same side of the plane right side or left side of the side wall panel B that is linearly connected.
A fastening piece 7 that is fixed to a suitable position in the longitudinal direction of the rear surface via a screw 6 or the like, and a first joint member 1F of the adjacent side wall panel B that extends from the piece 7,
The second joint member 2F is formed with an elastic locking piece 8 that first extends horizontally in the direction of the second backing frame 4E on the other side that is not fixed, and is further bent toward the back surface of the side wall panel B, and the second joint member 2F is formed at a right angle. A fastening piece 7 that is fastened to an appropriate position in the longitudinal direction of the back or side surface of the second backing frame 4E on the same side as the first joint member 1F in the side wall panel B to be connected, via screws 6, etc., and the fastening piece 7 It is formed with an elastic locking piece 8 bent from the end via a right-angled inclined piece 9.

Both the elastic locking pieces 8, 8 of the first joint member 1F and the second joint member 2F are connected to the circumferential edge D.
It is bent into the same shape as the locking piece 4D, and a hooking piece 10 is bent into a dogleg shape at its tip.

And the wall mounting surface 1C around the waterproof pan C corner
The side wall panel B adjacent to the corner is placed on top and held in an upright position. Furthermore, the second backing frame 4E of the side wall panel B adjacent at right angles is fitted into the second joint member 2F of the side wall panel B, thereby elastically engaging the hooking piece 10 and the bending piece 1E. The two side wall panels B and B constituting the corner are erected on the wall mounting surface 1C of the waterproof pan C in a connected state.

At this time, since the side wall panels B and B are connected at right angles, the side wall panels themselves stand on their own, eliminating the need for support by people or supporting materials. After such work, the side wall panels B are sequentially assembled one by one so that the bent piece 1E of the backing frame 4E located on the other side of the side wall panel B adjacent to the hooking piece 10 is elastically engaged. They are fitted together to form a side peripheral wall 7 (FIG. 7). At this time, for the side wall panel B which is the final assembly order, as shown in Fig. 8, the adjacent side wall panel B was elastically deformed toward the indoor side using the elastic force of the second joint member 2F. After that, the side wall panel B, which is the final assembly order, is installed, and the adjacent side wall panel B is installed again to form the side peripheral wall 7.

The door frame H is formed by a frame body 1H made of extruded aluminum material, and the upper end thereof is provided with a fitting groove J formed between the locking piece 4D of the rotating edge D and the hanging piece 3D. A door is formed by integrally forming a contacting rising piece 3H upright, and sliding the rising piece 3H in sliding contact within this fitting groove J and sliding it back and forth to the panel I of the adjacent chamber with the entrance 2I open. After alignment, the intervening frame portion 1I fixed to the tip of the frame H is directly attached and fixed to the second backing frame 4E via the screws 6, or in the case of a corner, indirectly attached to the adjacent side wall via the angled joint member 11. Fasten screw 6 to the second backing frame 4E of panel B.

Since the room can be adjusted in and out in this way, it is very easy to align the panel I of the adjacent room with the tip of the door frame H, and there is a risk that a gap may occur between the entrance 2I and the tip of the door frame H. There is no such thing.

[Function and effect of the idea]

Since the present invention is constructed as described above, it has the following advantages.

By pulling down the pull-down piece of the rotating edge fixed to the ceiling panel using a tool, etc., the locking piece elastically engages with the bent piece of the lining frame on the back of the side wall panel, and the ceiling panel is placed on the side wall panel. can be connected together.

Therefore, unlike the conventional simple fitting method, the side wall panels do not rattle or make strange noises, and do not impair the usability of the unit room.

Fill the space between the pull-down piece of the rotating edge fixed to the ceiling panel and the stepped surface formed on the upper surface of each side wall panel erected around the periphery of the waterproof pan with caulking material. Since the side wall panel does not wobble against the rotating edge, there is no peeling or cutting of the caulking material, and there is no risk of air leakage or water leakage.

Since this caulking material has the function of bonding the ceiling panel and the side wall panel via the circumferential edges, the ceiling panel can be more firmly attached to the side wall panel.

In this way, the intended purpose can be achieved.
