Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a panel used for assembling a corner part when constructing a unit bathroom or the like.

[Conventional technology]

When constructing a unit bathroom or the like, the following method has conventionally been used to assemble corner sections using panels with wall structures such as tiles adhered to their surfaces. That is, as shown in FIG.
Ribs 13 are provided on the back surfaces of the substrates 12 of the panels 11, 11a, and connecting fittings 14 are attached to the ribs 13 at appropriate intervals using tapping screws 15 or the like. After the panels 11, 11a are set up in the built-in position, as shown in FIG. By holding the inside of the rib 12 with the tip of the panel 1
1a and 11b are connected at right angles.

However, in the conventional construction method described above, the corner portions are assembled by butting the ends of the panels 11a and 11b at right angles on site. Therefore, there is a problem in that the wall components 16 such as tiles or ceramic plates attached to the surface of the panel 11 collide with each other due to butting, often resulting in damage such as chips, cracks, and cracks.

Damaged wall structures 16 must be replaced, which results in an increase in man-hours. Furthermore, especially when the panel 11 is made of a large tile or ceramic plate as the wall structure 16, the cost required for replacement is extremely high, leading to high costs.

Therefore, as a means for solving the above-mentioned drawbacks, a corner wall panel described in Japanese Patent Application Laid-Open No. 61-176355 has been proposed. As shown in FIG. 8, this is made up of two wall panels 21 and 22 which are bendably connected by hinges 25 at side edges 23 and 24, respectively.

[Problem that the invention attempts to solve]

By the way, in the hinge 25, by reducing the thickness of the central portion, a bent portion 26 that can be bent freely is formed. Therefore, the bent portion 26 has a drawback of low reliability in terms of strength.
Particularly when large tiles or ceramic plates are attached, the panels 21 and 22 are heavy, and the bent portion 26 of the hinge 25 is likely to crack. Furthermore, if even a slight crack occurs, there is a problem in that the caulking material leaks out to the back side of the hinge 25 when applying caulking to the corner because the thickness of the bent portion 26 is small.

In addition, in the embodiment described in the above publication, only the side edge of one wall panel 21 is formed at right angles, so two types of wall panels 21 are required for assembling the corner part.
This method has the disadvantage that 1 and 22 must be prepared. Furthermore, when the corner portion is constructed, the hinge 25 is folded in half, so the internal stress in the bent portion 26 of the hinge 25 becomes extremely large, causing further cracking and breakage. It has an easy structure.

[Means for solving problems]

This invention was created as a result of intensive research by the inventors to solve the above problems, and its feature is that a wall structure such as a tile or ceramic plate is arranged on the surface of the board. Two of the installed panels are
A pair of panels bendably joined by a long hinge, wherein a rib is provided on the side edge of the back surface of each board on the connecting side of each panel,
The elongated hinge is formed by integrally molding a bent part made of a soft material and a fixed part made of a hard material provided on both sides of the bent part, and the elongated hinge is attached to the outer surface of the rib of each of the panels. The fixed parts of each are fixed.

[Effect]

In the panel pair according to the above configuration, the bending part of the long hinge that bendably connects the panels is made of a soft material, so that the thickness of the bending part is the same as the fixed part on both sides. can have.
Therefore, cracks are much less likely to occur. Furthermore, by providing a sufficient thickness, reliability in terms of strength can be obtained even when the panel is heavy.

In addition, in the panel pair of the present invention, since the panels are foldably joined by long hinges, there is no need to butt the panels together when assembling the corner portions at the construction site of a unit bathroom or the like. Therefore, damage such as chipping or cracking does not occur to the wall structure on the back surface of the substrate. To erect the proposed panel pair, the panels connected by long hinges should be folded and transported to the construction site with their surfaces facing each other, and then opened at right angles at the erecting position, so work could be done from the indoor side. It can be carried out.

Furthermore, in the caulking work after assembling the corner section, the long hinge serves as a backing material for the caulking material, so that the waterproof effect in the corner section of a unit bathroom or the like is ensured.

〔Example〕

Hereinafter, details of the present invention will be explained based on drawings showing embodiments.

FIG. 1 is a drawing showing a panel pair 1 according to the present invention disassembled into panels 2, 2 and a long hinge 3, and shows a state in which the panels 2, 2 are folded and their surfaces face each other. What is shown in FIG. 2 is a view of the panel pair 1 of the present invention when it is opened and viewed from the front side. The panel 2 consists of a substrate 4 and a wall structure 7, such as a tile or a ceramic plate, arranged on the surface of the substrate 4. In this embodiment, a single large ceramic plate having approximately the same dimensions as the substrate 4 is used as the wall structure 7. Ribs 5, 5 are provided on the side edge of the back surface of the substrate 4, at least on the connection side. The ribs 5 are formed by, for example, manufacturing the substrate 4 from a steel plate and bending the side edges of the steel plate toward the back side. In this embodiment, ribs 6, 6 are also formed on the upper and lower edges of the substrate 4.

Long hinge 3 connecting panels 2 to 2
In this example, fixing portions 3b made of a hard material are integrally molded on both sides of a bent portion 3a made of a soft material. An example of manufacturing the elongated hinge 3 is one in which soft vinyl chloride is used for the bending part 3a, hard vinyl chloride is used for the fixing part 3b, and both are integrally molded by extrusion molding. Furthermore, the entire long hinge 3 is manufactured to have the same thickness. Note that the length of the bent portion 3a is, for example, when the width dimension of the long hinge 3 is about 50 mm and the thickness dimension is about 1.5 to 2 mm.
Made to approximately 9mm. Of course, the above dimensions are not limited to these, and may be changed as appropriate depending on the embodiment.

In order to fix the long hinge 3 to the panels 2, 2, for example, as shown in the plan sectional view of FIG. Tapping screw 10,10
You can attach it using etc.

By the way, as mentioned above, Japanese Patent Application Laid-Open No. 61-176355
In the wall panel described in the publication (see FIG. 8), the hinge 25 is folded at 180 degrees when the corner portion is assembled. Therefore, extremely large bending stress acts on the bent portion 26, making it extremely likely that cracks and breakage will occur.

In contrast, in the present invention, the long hinge 3 extends in a straight line when the panel pair 1 is folded for transportation, loading, etc. (see Figure 1), and when assembling the corner part, the long hinge 3 extends in a straight line. The bent portion 3a made of a soft material is simply bent at a right angle.
As described above, in the present invention, since the bending angle of the long hinge 3 is 90 degrees, the bending stress generated in the bent portion 3a is small. Therefore, cracks are extremely unlikely to occur in the long hinge 3.

In addition, as in the illustrated embodiment, each panel 2, 2
If ribs 5, 5 are provided symmetrically on both side edges of the same panel 2 when manufacturing the proposed panel pair 1,
It will be sufficient to prepare two sheets. Said Japanese Unexamined Patent Publication No. 1983-
The wall panel described in Publication No. 176355 uses two types of panels 21 and 22 (see FIG. 8) having different shapes, so they are not compatible and the manufacturing efficiency is poor. In contrast, in the present invention, one type of panel 2
Since it is sufficient, production efficiency is very high.

FIG. 4 shows an embodiment of another aspect of the present invention. The feature of this embodiment is that the holding parts 30, 30 are bent at right angles at both ends of the long hinge 3.
This is because we have established the following. As a result, the long hinge 3
The rigidity of the long hinge 3 can be increased, and the contact area between the long hinge 3 and the ribs 5, 5 of the substrates 4, 4 can be increased to prevent the long hinge 3 from falling off.

FIG. 5 shows a further embodiment of the present invention. In this embodiment, reinforcing hinges 8 are attached to appropriate positions at the top, bottom, and middle of the long hinge 3. Thereby, the strength of the bent portion 3a is improved, and a further crack prevention effect can be exhibited.

The proposed panel pair 1 can be used not only for unit bathrooms but also for various units using panels such as toilet rooms, shower booths, sauna booths, etc.

Furthermore, the panel pair 1 of the present invention is not limited to being used for building a corner part, but can also be used for building a flat part of a wall surface. In this case as well, excellent effects such as improved waterproofness between the panels and, depending on the situation, no need for caulking material can be brought about.

[Effect of idea]

As is clear from the above description, in the panel pair according to the present invention, the bent portions of the long hinges connecting the panels are made of a soft material, so that the bent portions have sufficient thickness. This makes it extremely difficult for cracks to form. In particular, when a pair of panels is manufactured using heavy panels made of large tiles or ceramic plates, the reliability in terms of strength is far higher than that described in JP-A-61-176355. Furthermore, since cracks are less likely to occur in the bent portions of the long hinges, the lining effect of the caulking material is ensured, and the waterproof performance at the corner portions is improved.

In this way, the present invention exhibits great effects even with slight improvements in structure.
