A so-called sandwich structure integrally formed as a single panel by bonding with an agent, and a structure in which a gypsum board is attached to the back surface of a design steel plate to provide heat insulation are known.
JP 2001-207586 A

For a wall panel provided in such a bathroom, the design surface looking into the bathroom is very important in appearance. However, since the conventional wall panel is a single part that is integrated with the design plate by attaching a reinforcing plate, a heat insulating material, etc. with an adhesive, the entire wall panel can be replaced if the design surface is damaged. Necessary.
For this reason, when the design surface is damaged on the production line, the wall panel itself is disposed of, and the burden of disposal costs increases as the amount of waste increases.
In addition, at the construction site, it is necessary to replace the entire wall panel, and the bathroom cannot be assembled until a new product (wall panel) is obtained. Along with this, there is a delay in other work processes accompanying it. Therefore, it was a big burden for the contractor, the contractor, and the panel maker.

  An object of the present invention is to provide a wall panel that can be easily coped with when a design surface is damaged.

  In order to achieve the above object, a feature of the present invention is that a wall panel provided with a design board facing the indoor side and a base board provided facing the design board, the design board is attached to the base board. A design-side rib projecting in a direction perpendicular to the design plate surface is provided on the surface on the opposite side, and the base plate is provided with a base-side rib projecting in a direction orthogonal to the base plate surface on the surface facing the design plate, The design side rib and the base side rib are fitted together to join the design plate and the base plate.

  According to the present invention configured as described above, the design plate and the base plate are fitted together with the plate-frame-shaped design side ribs and the base side ribs formed on both sides, so that the wall can be bonded without using an adhesive. Since the panel can be formed integrally, even if the design surface is damaged, it can be dealt with by replacing only the design plate. That is, since the design plate and the base plate can be handled as separate parts, even if the design surface is damaged, it is not necessary to replace the wall panel completely, and only the design plate needs to be replaced.

For example, when the design surface is damaged at the construction site, it is not necessary to wait for the acquisition of a new design plate, and the assembly of the room can be continued with the base plate. And a wall can be completed by fitting in a base board after acquiring a new design board. Therefore, other construction processes are not delayed.
Moreover, since only the design plate can be exchanged in the assembled state, it is possible to easily cope with future interior changes and the like.
Furthermore, it is possible to effectively use the space formed between the design plate and the base plate. For example, a heat insulating material can be provided.

Further, in the production line, even if the design surface is damaged, it is only necessary to discard the design plate, and the burden of disposal cost is reduced.
Furthermore, since the base plate can be made common to the design plates required for many types, the production efficiency can be improved.

  Another feature of the present invention is that the design side rib protrudes in a direction orthogonal to the design plate surface and is formed in a plate frame shape along a substantially outer periphery of the design plate, and the base side rib is orthogonal to the base plate surface. It protrudes in the direction to be formed and is formed in a plate frame shape along the substantially outer periphery of the base plate.

  According to this invention, the design plate and the base plate are fitted together by the plate frame-shaped ribs at the outer peripheral portion thereof, that is, the inner peripheral surface of one plate frame-shaped rib and the outer peripheral surface of the other plate frame-shaped rib are closely attached. Thus, since the wall panel is integrally formed, a sufficient fitting surface can be secured and a good joined state can be maintained, and the strength of the wall panel itself can be made appropriate.

  Another feature of the present invention is that the design side rib protrudes in a direction orthogonal to the design plate surface and is formed in a plate frame shape along a substantially outer periphery of the design plate, and the base side rib is orthogonal to the base plate surface. And a dividing rib that divides the region surrounded by the plate-shaped rib into a lattice shape, and the base-side rib includes the lattice. The design side ribs of the plurality of design plates are fitted into each of the divided regions, and the plurality of design plates are joined to the one base plate.

  According to the present invention, since a plurality of divided design plates are provided as one wall panel, when the design surface is damaged, only the damaged design plate is replaced and the remaining design plates are replaced. Can be used as is. That is, it is possible to reduce the design surface to be replaced. As a result, cost merits such as material costs and disposal costs can be obtained.

Another feature of the present invention is that the design-side rib and the base-side rib are formed with engaging portions that engage with each other on the mating surfaces.
According to this invention, joining of a design board and a base board can be performed reliably.

Another feature of the present invention resides in that the base plate includes adjusting means for adjusting the installation height in the base side rib.
In the present invention, a space is formed between the design plate and the base plate, and further, ribs are formed in the installation portion for installing the base plate on the floor, etc., so that the installation height is adjusted using them. Adjustment means can be provided. And this adjustment means makes it possible to adjust the height of the base plate and the left / right inclination, and it becomes easy to install the wall panel in a state suitable for the site.
For example, it is possible to adjust the height of the base plate by adjusting the position of the screw provided on the rib formed on the floor installation portion of the base plate with a screw that advances and retreats along the base plate surface forming direction.

Another feature of the present invention is that the design-side rib and the base-side rib have notches formed at arbitrary positions.
According to this, pipes (for example, water supply piping, hot water supply piping, gas piping, electric piping, etc.) and cables between two plates are effectively used in the space formed between the design plate and the base plate. Can be arranged along. This increases the degree of freedom in designing the room.

Hereinafter, a wall panel according to an embodiment of the present invention will be described with reference to the drawings.
1 to 5 show a bathroom wall panel as a first embodiment, FIG. 1 is an overall perspective view of the wall panel, FIG. 2 is an exploded perspective view of the wall panel, and FIGS. 3 to 5 are wall panels. The cross-sectional view of is represented.

In the present embodiment, for example, polyethylene terephthalate is used as the material of the design plate 20, and expanded polystyrene is used as the material of the base plate 30.
The design board 20 is a board facing the bathroom side, and the surface thereof becomes a design surface 21 (decorative surface). On the back surface 22 of the design plate 20, a plate-like rib 23 protruding in a direction orthogonal to the plate surface is formed. The rib 23 is formed in a plate frame shape in parallel with the outer peripheral line at a predetermined distance from the outer peripheral edge of the design plate 20, and includes an upper rib 23 a formed along the upper edge of the design plate 20. The left rib 23b is formed along the left edge, the right rib 23c is formed along the right edge, and the lower rib 23d is formed along the lower edge.
The rib 23 corresponds to the design side rib of the present invention, and is hereinafter referred to as the design side rib 23 also in the present embodiment.
The design side rib 23 is integrally formed with the design plate 20, but may be formed separately and joined to the design plate 20 with an adhesive or the like.
The design plate 20 is formed with two openings 24a and 24b for attaching the hot and cold mixing tap V (see FIG. 4). Further, the left rib 23b is formed with a hot water supply pipe P1 connected to the hot water / water mixing tap V and a notch 25 for drawing the water supply pipe P2 out of the wall.

The base plate 30 is provided to face the back surface 22 of the design plate 20 and is for maintaining the strength of the housing as a bathroom wall.
The base plate 30 has a plate-like rib 33 protruding on a surface 31 (here, a surface facing the design plate 20 is a surface) protruding in a direction perpendicular to the plate surface. The rib 33 is formed in a plate frame shape along the outer peripheral edge of the base plate 30, and an upper rib 33 a formed along the upper edge of the base plate 30 and a left side formed along the left edge. The rib 33b includes a right rib 33c formed along the right edge and a lower rib 33d formed along the lower edge.
The rib 33 corresponds to the base-side rib of the present invention, and is hereinafter also referred to as the base-side rib 33 in the present embodiment.
The base-side ribs 33 are integrally formed with the base plate 30, but may be formed separately and bonded to the base plate 30 with an adhesive or the like.
The left rib 33b of the base plate 30 is formed with a hot water supply pipe P1 connected to the hot water mixing tap V and a notch 35 for drawing out the water supply pipe P2 to the outside of the wall.

The design side rib 23 of the design plate 20 and the base side rib 33 of the base plate 30 are formed so as to fit each other. In the present embodiment, the design side rib 23 is fitted inside the base side rib 33 when the design plate 20 is pushed toward the base plate 30, that is, the outer peripheral surface of the design side rib 23. The dimension is set so that 23out is in close contact with the inner peripheral surface 33in of the plate-side rib 33. Further, the protruding length of the design side rib 23 from the design plate back surface 22 and the protruding length of the base side rib 33 from the base plate surface 31 are set to the same dimension.
Accordingly, the wall panel 10 is aligned so that the design plate 20 faces the base plate 30 so that the design side rib 23 comes to the inside of the base side rib 33, and the design plate 20 is pushed into the base plate 30 as it is. Are joined together and do not rattle.

Further, when assembling a bathroom by arranging a plurality of wall panels 10, as shown in FIG. 5, the water stop member S is sandwiched between the base side ribs 33 of the two base plates 30, and the back surface 32 of the base plate 30. The connecting bracket J is driven and connected across the two base side ribs 33. At this time, even if the gap between the base plates 30 is increased by interposing the water-stopping member S, the gap can be covered from the front side with the outer peripheral portion of the design plate 20, so that the joint can be reduced. Good looking. Further, the area of the caulking C that fills the joint can be narrowed, and the cleaning property is improved.
In this case, the outer size of the design plate 20 is made larger than the outer size of the base plate 30 so that the outer peripheral portion of the design plate 20 slightly protrudes from the outer peripheral portion of the base plate 30 in the front view. .

Moreover, since the space A is formed between the design board 20 and the base board 30, the wall panel 10 arrange | positions the hot water supply pipe P1 and the water supply pipe P2 using this space A, as shown in FIG. can do. In this example, the water inlet and the hot water inlet of the hot and cold mixing tap V are inserted into the two openings 24a and 24b formed in the design plate 20, and the hot and cold mixing tap V main body is fixed to the design plate 20, and the hot water supply pipe P1 and The water supply pipe P <b> 2 is arranged along the plate surface direction and is drawn out from the notches 25 and 35 formed in the design side rib 23 and the base side rib 33.
In the conventional wall panel, since it is formed as an integral part, it was not possible to arrange the piping in the wall in this way. However, in the wall panel 10 of the present embodiment, the design plate 20 and the base plate 30 Since the space A is formed between them and the design plate 20 is provided separately from the base plate 30, before the design plate 20 is fitted into the base plate 30, the hot water mixing tap V or hot water supply is provided on the design plate 20. By attaching the pipe P <b> 1 and the water supply pipe P <b> 2, piping in the wall panel 10 becomes possible. For this reason, the freedom degree of bathroom design spreads and construction property improves.

  Further, the space A formed between the design plate 20 and the base plate 30 can be used as an area filled with a heat insulating material or the like, and a gas pipe or an electric pipe can be provided. .

  In the wall panel 10 thus configured, when the design plate 20 is damaged, the design plate 20 may be removed from the base plate 30 and replaced. In this case, since the damaged design plate 20 is not useful, it can be easily removed by making a hole in the design plate 20 and pulling the opening, or screwing a screw or the like and pulling the screw together. Then, when the new design plate 20 is fitted into the existing base plate 30, the restoration is completed.

According to the bathroom wall panel 10 of the present embodiment described above, even when the design surface 21 is damaged, it can be dealt with by replacing only the design plate 20.
For example, even if the design surface 21 is damaged at the construction site, the assembly of the bathroom can be continued with the base plate 30, so that other construction steps are not delayed.
Moreover, even if it is necessary to change the interior in the future, the existing base plate 30 can be used as it is, and only the design plate 20 can be replaced.

Further, in the production line, even if the design surface 21 is damaged, only the design plate 20 needs to be discarded, and the burden of disposal cost is reduced.
Furthermore, since the base plate 30 can be made common to the design plates 20 required for various types, a dedicated line can be formed, and the production efficiency can be improved.

Moreover, since the hot water supply pipe P1 and the water supply pipe P2 can be arrange | positioned between the design board 20 and the base board 30, the freedom degree of bathroom design spreads and a workability improves. In addition, a heat insulating material or the like can be provided by effectively using the inner space A.
Furthermore, the joint between the wall panels 10 can be reduced, and the aesthetics and the cleaning property can be improved.
Further, since the wall panel 10 is integrally formed by fitting the design plate 20 and the base plate 30 with the plate frame-like ribs 23 and 33 on the outer peripheral portion thereof, a sufficient fitting surface can be secured and good bonding is achieved. While maintaining a state, the intensity | strength in wall panel 10 itself can be made appropriate.

Next, a bathroom wall panel according to a third embodiment will be described. FIG. 8 is an exploded perspective view of a wall panel for a bathroom according to the third embodiment.
As shown in the figure, the wall panel 70 of the third embodiment is obtained by fitting four design plates 80 to one base plate 90.
Each design plate 80 has a plate surface that is half the size of the base plate 90 in the vertical and horizontal directions. Similar to the first embodiment, the design plate 80 has a plate frame-like design at a predetermined distance from its outer periphery. Side ribs 83 are formed.
The base plate 90 includes base-side ribs 93 including plate frame-like ribs 93a formed along the outer peripheral edge thereof and lattice-like ribs 93b that divide the region surrounded by the plate frame-like ribs 93a into four. In the lower left part of the plate frame-like rib 93a, a pipe drawing notch 95 similar to that of the first embodiment is formed.

The wall panel 70 is integrally formed by fitting the design side ribs 83 of the design plate 80 inside the base side ribs 93 surrounding the region divided into four by the lattice ribs 93b. In this example, the design plate 80 on the lower left side is used in which mounting openings 84a and 84b for the hot and cold mixing tap V and a notch 85 for drawing out the pipe are formed.
In this case, it is not necessary to use all the design plates 80 having the same design, and those having different design surfaces may be used in combination.
According to the third embodiment, in addition to the operational effects of the first embodiment, since the design plate 80 divided into a plurality of pieces as one wall panel 70 is provided, when the design surface is damaged, Only the damaged design plate 80 can be replaced, and the remaining design plate 80 can be used as it is. That is, it is possible to reduce the design surface to be replaced. As a result, cost merits such as material costs and disposal costs can be obtained.
Also in this embodiment, the fitting of the design side rib 83 and the base side rib 93 may be reversed.

Next, modifications of the above embodiments will be described.
In each of the above-described embodiments, when it is desired to securely join the design plate and the base plate, as shown in FIG. 9, the design side rib 103 formed on the design plate 100 and the base side rib formed on the base plate 110 Engaging portions may be provided on the contact surfaces 103out and 113in with 113. In this example, a wedge-shaped protrusion 114 is formed on the inner side surface 113in of the base side rib 113, while the ribs 103, 113 of both plates 100, 110 are fitted to the outer side surface 103out of the design side rib 103. A recess 104 that engages with the protrusion 114 is formed. In this case, the engagement portion may be provided continuously along the contact surfaces 103out and 113in of the ribs 103 and 113, or may be provided partially.

Further, as shown in FIG. 10, the first plate frame-like rib 123a and the first rib 123a of the design plate 120 are closely attached to the outer side surface 133out and the inner side surface 133in of the base side rib 133 of the base plate 130. You may make it the 2 sheet frame structure which consists of 2 plate frame-shaped rib 123b. In this example, since the base side rib 133 is sandwiched between the design side ribs 123 (123a, 123b), the joining of both the plates 120, 130 is ensured.
The base plate side may have a two-frame structure, or both the design plate and the base plate may have a two-frame structure and may be fitted together.

Next, a configuration for facilitating the installation work of the wall panel will be described as a modification of each of the above embodiments.
