Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in the connecting structure of wall panels that constitute the wall surfaces of unit baths, washbasin units, etc.

[Prior Art] A conventional example of this type of wall panel connection structure will be described with reference to FIGS. 3 to 5. 3 to 5 are horizontal sectional views, respectively, and in the conventional example shown in FIG. 3, side plates 1a and 2a are erected on the side portions of the wall panels 1 and 2 toward the rear. , a pillar member 3 having a U-shaped cross section holds these side plates 1a and 2a. The wall panels 1 and 2 are erected at a predetermined interval between their side plates, and a joint material 4 is pushed into this interval.

In the conventional example shown in FIG. 4, side plates 1 of panels 1 and 2
a, 2a and side plates 1a, 2a of wall panels 1, 2
is bent in a dogleg shape in cross section, and wall panels 1,
The space between the wall panels 1 and 2 is approximately hexagonal, and a joint material 5 having a shape that widens toward the back is pushed between these wall panels 1 and 2. The pillar material 6 has a box-shaped cross section, and is integrally formed with bent portions 6a and 6b for holding the side plates 1a and 2a.

In the conventional example shown in FIG. 5, no joint material is used, and protrusions 1b, 2b are formed on the side plates 1a, 2a of the wall panels 1, 2, and the protrusions 1b, 2b are formed on the column material 6. , 2b are integrally formed with folded portions 6c and 6d that are bent in two stages so as to wrap around them.

[Problems to be solved by the invention] In the conventional example shown in FIGS. 3 and 4, the side plates 1a, 2a are pressed against the pillars 3, 6 by the elasticity of the joint materials 4, 5, This connects the wall panels 1 and 2, but when using joint material in this way, the following problems occur.

When applying a pattern to a panel, the joint material stands out between adjacent panels, and the continuity of the pattern is lost.

Mold tends to form on the joint material. Particularly when wall panels are installed in a bathroom, mold tends to form due to moisture.

When used for a long period of time, the joint material loses its elasticity, making it easier for the joint material to fall out.

The joint material will be exposed in the form of tape, which is unsightly.

According to the conventional example shown in FIG. 5, the above problems are solved because no joint material is used, but the side plates 1a and 2a of the wall panels 1 and 2 are made of pillar materials
Since it is held by the elasticity of There was a fear of slipping out. In particular, if a large forward pulling force is applied, for example when a grip bar is attached to a wall panel, there is a high possibility that the panel will come off.

Furthermore, in the conventional example shown in FIG.
However, there were also problems in that the bending portions 6c and 6d were complicatedly bent, and the manufacturing thereof was troublesome and high in cost.

[Means for solving the problem] The wall panel connection structure of the present invention is such that side plates are provided on the sides of the wall panels to stand behind them, and the side plates of adjacent wall panels are overlapped with each other. It has a structure in which this is inserted into a slit provided in a pillar material having a hollow box-shaped cross section and is held between the pillar materials. The side plates each have a protrusion extending in the vertical direction and having a dogleg-shaped horizontal cross section and protruding in a direction opposite to the stacking direction. A plate-shaped folded part is formed at the slit edge of the column, and the tip of this folded part touches the inclined surface of the protrusion on the front side of the panel. are locked in contact.

[Function] In the wall panel connection structure of the present invention, the column materials sandwich the side plates, and the wall panels are connected without using joint material.

In addition, the end edge of the folded part of the pillar material is in contact with the inclined surface on the panel side of the protrusion on the side part, and when an external force is applied in the direction of the wall panel coming out, the folded part will be forced in the direction of approaching each other. As a result, the folded portion acts as if it bites into the protrusion or the side plate, and the panel is reliably prevented from coming off.

[Example] Examples will be described below with reference to the drawings.

FIG. 1 is a horizontal sectional view showing a wall panel connection structure according to an embodiment of the present invention, and FIG. 2 is a perspective view of the main parts of the wall panel.

Reference numerals 1 and 2 denote wall panels, and side plates 1a and 2a are provided on the side portions thereof and stand upright toward the rear side, and these side plates 1a and 2a are overlapped with each other. The side plates 1a and 2a have protrusions 1b,
2b are provided, and these protrusions 1b, 2b protrude in the direction opposite to the overlapping direction and extend in the vertical direction as shown in FIG. Projections 1b, 2
b has a dogleg-shaped horizontal cross section;
As shown in the figure, it has two inclined surfaces S and T.
Reference numeral 7 denotes a pillar material, which holds the superimposed side plates 1a and 2a therebetween. The pillar material 7 has a rectangular cross-sectional shape, and has a slit 8 in the center of the surface in contact with the wall panels 1 and 2 for receiving the side panels 1a and 2a, and the surface with this slit 8 is the same as that of the pillar material 7. Folded inward, folded portions 7a and 7b are integrally formed. The end sides of the folded portions 7a, 7b are in contact with the inclined surfaces T on the front sides of the panels 1, 2 of the protrusions 1b, 2b.

Note that the reference numeral 9 indicates a sealing material sandwiched between the side plates 1a and 2a.

Such a connection structure can be used, for example, for wall panels 1 and 2.
The side plates 1a and 2a are stacked on top of each other with a sealing material 9 interposed between them, and connected by pressing from the front side of the wall panel as if inserting them into the slits 8 of the pillars 7 that have been erected in advance. Work is done. After the connection work is completed, the end sides of the folded parts 7a and 7b are aligned with the protrusions 1b and 2b as shown in the figure.
The wall panels 1 and 2 are connected by being held by the pillars 7, and the above-mentioned folded portions 7a and 7b and the protrusion 1
Due to the engagement with b and 2b, there is no fear that the wall panels 1 and 2 will come off even if an external force is applied to the wall panels 1 and 2 in the direction of their coming off. That is, when an external force is applied to the wall panels 1, 2 in the direction of pulling out, the folded portions 7a, 7
A force is applied in the direction in which the folded portions 7a and 7b approach each other, and this causes the folded portions 7a and 7b to
b, 2b or the side plates 1a, 2a, and the column does not open out like the conventional column 6.

In addition, in the present invention, in order to make the folded parts 7a, 7b bite into the protrusions or side plates in this way, the contact angle between the slopes of the protrusions 1b, 2b and the folded parts 7a, 7b is adjusted appropriately. It is important to be selective. In the present invention, it is preferable to select the contact angle θ to be 100° or less, particularly 95° or less, particularly 90° or less, as shown in FIG.

In the above embodiment, the protrusions 1b and 2b are provided in a part of the side plates 1a and 2a in the longitudinal direction, but by providing them in a part in this way, the sealing material 9 and the side plates 1a and 2a are The effect of increasing the contact area with the material and increasing the sealing effect is obtained. Further, the resistance when pushing the protrusions 1b, 2b into the slit 8 is reduced, and the effect of easily connecting the wall panels is achieved.

However, in the present invention, it is clear that the protrusions 1b, 2b may be provided over the entire vertical direction of the side plates 1a, 2a. In addition, in this invention,
The side plates 1a and 2a may be provided integrally with the front part of the panel as shown, or may be provided by joining pieces having an L-shaped cross section.

In the present invention, the wall panels 1 and 2 can be made of various materials such as metal panels such as steel plates or resin panels such as PVC.

[Effects of the invention] As described above, according to the connection structure of the invention, it is possible to connect extremely strong wall panels without any fear of the panels coming off. This invention does not require joint material, provides continuity to the pattern of the wall panel, and does not cause mold to form on the joint material.
It has excellent effects such as high durability and good appearance. Further, in the present invention, the shape of the pillar material is relatively simple, making it easy to manufacture and inexpensive.
