Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a plurality of wall panels forming a unit bath at an angle.

[0002]

2. Description of the Related Art In some unit baths, a wall surface is formed by combining a plurality of wall panels. And
In order to easily connect the wall panels from the inside of the bathroom at an angle, a structure shown in FIG. 5 has been conventionally used.

In the case of FIG. 5, a pair of wall panels 1a, 1b.
2 is a plan sectional view of a joint piece 7 insertion portion in which the two are mutually connected at a right angle, and a dedicated corner frame 40 is separately used to connect the wall panels 1a and 1b at such a corner portion. That is, the corner frame 40 is made of an extruded mold material such as aluminum like the frames 2a and 2b forming the wall panels 1a and 1b, and the frames 2a and 2b of the wall panels 1a and 1b are formed.
42 abutting on the joints 14a and 14b
a, 42b, the rear plate portions 10a, 10 of the frames 2a, 2b
Similarly to b, the holding portions 44a and 44b surrounding a part of the outer peripheral portion of the base portion 29 of the joint piece 7, and both portions 4
2a, 42b, 44a, 44b is integrally formed with a joint plate portion 46.

The procedure for connecting the wall panels 1a and 1b to each other using the corner frame 40 is as follows. First, joint pieces are attached to one wall panel, for example, the frame 2a of the wall panel 1a and the upper end, the lower end and the middle portion of the corner frame 40. 7
Insert and connect. And the connected wall panel 1a
And the corner frame 40 are placed together with the corner frame 40 on the corner portion of the waterproof pan (not shown), and the wall panel 1b and the frame 2b are also mounted on the corner frame 4.
Place adjacent to 0. Further, the joint pieces 7 are inserted into the upper and lower ends and the intermediate portion of the frame 2b and the corner frame 40, thereby completing the connection between the both wall panels 1a and 1b. That is, the joint portion 14 of the frames 2a and 2b
a, 14b and the joint portion 42a, 4 of the corner frame 40
2b is sandwiched by the recess 31 of the joint piece 7, and the two panels 1a and 1b are connected via the corner frame 40.

[0005]

However, the frame 2
In the connection between the a and the corner frame 40, since the joint piece 7 alone is weak in connection, the positional relationship between the frame 2a and the corner frame 40 may be displaced by the time of mounting on the waterproof pan, and in some cases, the joint piece 7 may be disconnected.
May come off and start over. Also, frame 2
Although the joint pieces 7 are inserted in two rows between a and the corner frame 40 and between the frame 2b and the corner frame 40, the joint piece 7 has a weak coupling force, and the upper end, the lower end and the middle of each frame. Since two joint pieces 7 are used for each part, the wall panels 1a, 1
The connecting force between the wall panels is weaker than when using one joint piece 7 for connecting b in the same plane. Therefore, since the wall panel is unstable until the assembly of the ceiling panel (not shown) is completed with the wall panel placed on the waterproof pan (not shown), great care must be taken during the assembly. As described above, the conventional technique has a problem that the assembly workability is impaired.

In order to improve the above problem, the wall panel 1a and the corner frame 40 are joined together by the joint piece 7.
Instead, a method of firmly fixing with screws or the like can be considered.
However, if you firmly fix it before placing it on the waterproof pan,
A slight deviation from the wall panel 1b after placing the waterproof pan cannot be corrected, and it becomes difficult to insert the joint piece 7. Also,
Even if it can be inserted, the gaps between the abutting portions of the wall panels 1a and 1b do not match, gaps occur between the wall panels 1a and 1b and the waterproof pan, and between the wall panels 1a and 1b and the ceiling panel. Since it is impossible to work from the outside of the bathroom due to the relationship with the building, both wall panels 1a and 1b and the corner frame 40 are disassembled and reassembled. Therefore, even if the above problem is solved, a new problem will occur.

The present invention was devised in view of the above circumstances, and enables a wall panel to be assembled at an angle by using a corner frame so that a necessary coupling force can be secured and the assemblability is also improved. The challenge is to prevent damage.

[0008]

The present invention adopts the following constitution in order to achieve the above-mentioned object. That is, the frame is made of a mold material in which openings and joints are formed along the longitudinal direction, and the corner frame is made of a mold material in which openings and protrusions are formed along the longitudinal direction. The corner frame is a space part formed by making the opening of the frame and the opening of the corner frame face each other, and a joint piece is inserted and fixed in this space, and the other wall panel and the corner frame are fixed. Engage and join the joint portion of the frame and the protruding portion of the corner frame.

Next, a procedure for connecting the wall panels 1a and 1b to each other will be described.

First, in the case of connecting flush with each other, the joint piece 6 having the structure shown in FIG. 2 is inserted into the lower end of the frame 2a of one wall panel, for example, 1a, upside down from FIG. The wall panel 1a is placed on a waterproof pan (not shown).

Next, while placing the other wall panel 1b on the waterproof pan, the lower end of the wall panel 1b is also fitted into the joint piece 6 so that the two wall panels 1a and 1b are flush with each other. Match each other. At that time, the side surface of the convex portion 32 of the joint piece 6 is at the end of the rear plate portion 10a, 10b of the frames 2a, 2b, and the side surface of the base portion 28 is also at the protruding portions 16a, 16b of the frames 2a, 2b, respectively. Since the recesses 30 of the joint piece 6 contact each other and sandwich the joint surfaces 14a and 14b of the frames 2a and 2b, the wall panel 1b can be easily positioned.

Subsequently, in a state where the both wall panels 1a and 1b are butted to each other, the openings 24 of the left and right frames 2a and 2b are formed.
The joint piece 7 having the structure shown in FIG. 4B is inserted into the space portion sandwiched by a and 24b. At this time, the joint piece 7 is caught by the projections 26a and 26b formed at the substantially intermediate positions of the entire lengths of the frames 2a and 2b in the longitudinal direction, and therefore does not drop further downward.

Subsequently, the joint piece 6 having the structure shown in FIG. 2 is inserted into the space between the left and right frames 2a and 2b, which is sandwiched by the openings 24a and 24b. At this time, the hooking protrusions 34 of the joint piece 6 make the front plate portion 8a,
8b and the end faces of the rear plate portions 10a and 10b, respectively, the joint piece 6 does not drop further downward.

As described above, the joint pieces 6 and 7 are simply inserted into the space between the openings 24a and 24b of the left and right frames 2a and 2b, and the recesses 30 and 31 are joined to the joints 14a of the frames 2a and 2b. , 14b so that the frames 2a, 2b are joined together.

Next, when connecting at an angle such as a corner portion, the corner frame 40 is attached to the wall panel 1a.
Alternatively, it may be fixed in advance to either one of 1b or 1b. In the case of FIG. 1, the corner frame 40 is attached to the wall panel 1a.
The projecting portion 45 of the corner frame 40 is securely engaged with a part of the joint portion 14a of the frame 2a, and then fixed using the screw 50.

The subsequent steps are the same as in the case where they are connected flush with each other, and the corner frame 40 or the corner frame 40 is connected.
After inserting the joint piece 6 into the lower end of the frame 2b of the wall panel 1b which is not fixed, the other wall panel is butted, and the joint piece 7 is inserted into the corner frame 40 and the frame 2b at a substantially intermediate position in the entire length in the longitudinal direction. The joint piece 6 may be inserted at the upper ends of the corner frame 40 and the frame 2b. In this way, even when connecting at an angle, the joint pieces 6, 7
The frame 2a and the frame 2b are joined together via the corner frame 40 only by inserting the rows.

After the left and right wall panels 1a and 1b are connected to each other so as to form a joint 22 having a predetermined width, the joint 22 is filled with a suitable resin sealing material.

[0025]

As described above, even when the wall panels 1a and 1b are fixed at an angle, the projecting portion 45 of the corner frame 40 engages with a part of the joint portion 16a of the frame 2a to attach to the screw 50. Since the corner frame 40 and the frame 2a are sufficiently secured, the positional displacement does not occur. Therefore, as in the case where the wall panels are connected in the same plane, the connecting pieces need only be used in one row, there is no difference in strength, and the connection between the wall panels when using two rows of conventional joint pieces is used. The lack of force is eliminated, and the assembly workability is not impaired and a new assembly problem does not occur.
