Description

  The present invention relates to a ceiling joint structure for hermetically closing a gap between a ceiling panel and a wall panel of a unit bath.

  In general, a unit bath connects a ceiling panel and a wall panel using a turning edge member. The turning edge member is formed with a joint receiving portion for engaging and fixing a ceiling joint for airtightly closing a gap formed between the ceiling panel and the wall panel (see Patent Document 1). .

  Here, when the ceiling panel is formed of resin, it is possible to turn the ceiling panel and integrally form the edge. However, an engaging portion for engaging the ceiling joint cannot be formed integrally with the turning edge portion formed integrally with the ceiling panel.

Accordingly, a resin joint receiving member having an engaging portion separately from the ceiling panel is required. This joint receiving member is fixed with screws or the like with a space in the horizontal direction with respect to the turning edge of the ceiling panel.

At this time, the joint receiving member may be stretched depending on the temperature environment in the bathroom, and may float in the horizontal direction between adjacent screws as shown in FIG. When the joint receiving member is lifted, the ceiling joint engaged with the joint receiving member is also floated in appearance, so that the design is deteriorated. Moreover, since the ceiling joint is not disposed at a predetermined position, a gap may be formed even when the ceiling joint is attached, which is not preferable from the viewpoint of airtightness.
JP 2005-307619 A

In view of the above-described problems, the present invention has a design and airtightness of the ceiling joint, without using the joint receiving member in the horizontal direction when the resin-made ceiling panel is integrally formed with the turning edge. An object of the present invention is to provide a ceiling joint structure for a good unit bath.

According to one aspect of the present invention,
A wall panel constituting the wall surface of the unit bath;
A resin-made ceiling panel in which a peripheral part is placed on the upper end of the wall panel and a hanging part formed integrally with the surface side of the wall panel is integrally formed;

According to the present invention, when a resin-made ceiling panel having an integrally formed turning edge is used, the joint receiving member does not float in the horizontal direction, and the unit has good design and airtightness of the ceiling joint. The ceiling joint structure of the bus can be provided.

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

An embodiment of a unit bus in the present invention will be described. The unit bath is provided with a waterproof pan for a washing place and a bathtub so as to be adjacent to the waterproof pan for a washing place, and a bath apron is attached so that the opening of the bathtub and the waterproof pan for the washing place is watertightly closed. Further, the wall panel 2 is placed in a watertight and airtight manner on the outer periphery of the bathtub and the waterproof pan for the washing place, and the ceiling panel 1 is placed on the upper end of the wall panel 2. The gap between the wall panel 2 and the ceiling panel 1 is closed in a watertight and airtight manner by the ceiling joint. Thus, the bathtub, the waterproof pan for the washing place, the bath apron, the wall panel 2 and the ceiling panel 1 form an airtight room space.

As shown in FIG. 1, the ceiling panel 1 in the present invention is made of a resin material such as HIPS, and a turning edge 30 for connecting and fixing the ceiling panel 1 and the wall panel 2 is integrally formed. . A first hanging part 3 is formed on the entire outer periphery of the ceiling panel 1 so as to hang downward. In addition, a second hanging portion 4 is formed on the inner side from the first hanging portion 3 by the substantially thickness of the wall panel 2. Further, a third drooping portion 5 is formed on the slightly inward side of the second drooping portion 4. As described above, the first drooping portion 3, the second drooping portion 4, and the third drooping portion 5 that protrude downward are integrally formed on the entire periphery of the peripheral edge of the ceiling panel 1.

The third hanging portion 5 is formed so that the drooping dimension is extremely smaller than that of the first hanging portion 3 and the second hanging portion 4. In addition, a reinforcing rib portion 6 is formed on the back side (outside the bathroom) of the ceiling panel 1.

The wall panel 2 is formed of a surface material 7 such as a decorative steel plate and a core material 8 such as a plaster board, asbestos, and glass wool. Various colors and patterns are attached to the surface material to improve the design of the unit bathroom, and by bending and processing the end, it is possible to connect floor pans, ceiling panels, and wall panels . It also plays a role in improving the strength of the wall panel itself. The core material is a strength member and has heat insulation properties, and the temperature in the unit bathroom is less affected by the outside air temperature. These surface material and core material are bonded and integrated with an adhesive or the like, except for both side edges of the surface material. With this configuration, the thickness of the wall panel 2 itself is suppressed to about 10 mm, and the weight is light, improving workability during manufacturing, transportation, and assembly. And it can be manufactured at low cost. Moreover, the wall panel 2 which improved the intensity | strength in which the steel plate etc. were stuck as a back surface material on the unit bathroom outer side of the wall panel 2 can also be used.

The ceiling panel 1 is attached in a state where it is placed on the upper end of the wall panel 2 at the peripheral edge. More specifically, the upper end portion of the wall panel 2 is in a state of being indented only between the first hanging portion 3 and the second hanging portion 4 formed in the concave shape of the ceiling panel 1. The second drooping portion 4 is disposed so as to contact the bathroom inner surface of the wall panel 2, and the first drooping portion 3 is disposed so as to contact the bathroom outer surface of the wall panel 2.

In addition, the lower end part 9 of the 2nd drooping part 4 of the surface side contact | abutted with the wall panel 2 is slightly beaten in the perimeter. Specifically, a concave clearance portion 10 opened downward is formed between the lower end portion of the second hanging portion 4 and the surface of the wall panel 2.

Next, the joint receiving member 11 fixed to the second hanging part of the ceiling panel 1 will be described. The joint receiving member 11 is made of resin, and plays a role of watertightly and airtightly closing a gap around the entire circumference of the ceiling panel 1 and the wall panel 2. The joint receiving member 11 is fixed to the second drooping portion 4 of the ceiling panel 1 by screws (fixing members) 12 that are attached at intervals in the horizontal direction.

The joint receiving member 11 has the same cross-sectional shape, and the upper end portion is a concave concave portion 13 attached so as to be sandwiched between the third hanging portion 5 described above. The lower end portion has a claw portion 14 formed so as to be caught by a concave clearance portion 10 opened downward between the lower end portion of the second drooping portion 3 and the surface of the wall panel 2. Thus, the joint receiving member 11 is prevented from bending in the horizontal direction by fitting the upper end of the joint receiving member 11 with the third hanging portion 5 of the ceiling panel 1. In addition, the joint receiving member 11 is prevented from being bent in the horizontal direction by fitting the lower end into a clearance portion 10 formed between the second drooping lower end 4 of the ceiling panel 1 and the surface of the wall panel 2. Yes.

Further, a screw fixing portion 15 that is attached with a space in the horizontal direction is disposed near the center in the vertical direction of the joint receiving member 11. Furthermore, a receiving member side engaging portion 17 that engages with a ceiling joint 16 described later is formed over the entire width direction below the upper end and above the screw fixing portion.

Next, the ceiling joint 16 will be described. The ceiling joint 16 includes a soft fin portion 18 made of an olefin-based elastomer that comes into contact with the ceiling panel 1 and the surface of the wall panel 2, so that the gap between the ceiling panel 1 and the wall panel 2 is hermetically sealed. It is watertightly closed.

A hard joint main body 19 is provided between the fins 18 located at the upper end and the lower end, and a projecting joint side engagement that engages with the recess of the joint receiving member 11 is provided on the back side of the joint main body 19. A joint 20 is formed.

According to the ceiling joint structure of the unit bath configured as described above, even if the space between the screws of the joint receiving member attached with a space therebetween is likely to be bent due to temperature deformation, Since the upper end and the lower end are respectively fitted in the third hanging portion 5 of the ceiling panel 1 and the clearance portion 10 formed by the wall panel 2 and the second hanging portion 4 of the ceiling panel 1, horizontal Directional misregistration is regulated. That is, since the horizontal deformation of the joint receiving member 11 due to temperature deformation is suppressed, the ceiling joint 16 does not bend in a wave shape. Thus, since the ceiling joint 16 can be positioned at a predetermined position over a long period of time, it is possible to provide a ceiling joint structure of a unit bath excellent in design and airtightness.

As shown in FIGS. 3 and 4, the joint receiving member 520 according to the comparative example of the present invention is not fitted as in the present invention, so that the horizontal displacement is not restricted. That is, since the horizontal bending of the joint receiving member 520 due to temperature deformation is not regulated, the ceiling joint 530 is bent in a wave.
