[Problems to be solved by the invention]
However, in such a structure, a connecting device must be separately attached to both the ceiling panel and the wall panel. That is, a pair of connecting tools that can be combined with each other and screws for attaching them are inevitably required, which increases the number of parts and the number of assembling steps, resulting in an increase in cost. In addition, in the conventional structure, since the connecting member is a separate part with respect to the ceiling panel, a gap is easily generated between them, and the inconvenience that the heat insulating property in the peripheral region of the connecting member cannot be sufficiently ensured also arises. I do.
[0006]
[Object of the invention]
The present invention has been devised in view of such inconveniences, and an object thereof is to provide a panel connection structure capable of reducing the number of assembly steps and the cost by reducing the number of parts. It is in.

It is another object of the present invention to provide a panel connection structure capable of improving heat insulation in a connection area between a ceiling panel and a wall panel.
[0008]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a structure for connecting an upper end portion of a wall panel and a ceiling panel,
The ceiling panel is provided integrally with a protrusion protruding toward the wall panel, while the wall panel is provided with a position control portion, and the protrusion of the ceiling panel is provided inside the position control portion of the wall panel. It is configured to be accepted and connected to each other. According to such a configuration, each panel can be connected without separately providing a connector or the like on the ceiling panel as in the related art. This makes it possible to reduce the number of components and the number of assembling steps required when connecting the panels, and to reduce the cost associated with the construction. Moreover, since the protruding portion is received inside the position restricting portion, the positioning of the ceiling panel can be easily performed without the ceiling panel protruding outside the wall panel. Further, since the protruding portion is integrated with the ceiling panel, airtightness and heat insulation between them can be ensured, and dew condensation on the outer surface of the wall panel can be effectively prevented.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, it is preferable to adopt a configuration in which the position restricting portion is configured to include a substantially vertical surface portion located along the projecting portion. With such a configuration, when the ceiling panel and the wall panel are connected, the position restricting portion and the protruding portion can be easily and firmly connected by various methods such as screwing and bonding, thereby improving workability. It becomes possible.
[0010]
Further, a configuration may be adopted in which the position restricting portion is configured by a concave groove formed in an upper end portion of the wall panel. With such a configuration, the ceiling panel and the wall panel can be connected only by receiving the protruding portion in the concave groove. As a result, the number of parts can be further reduced, and the reduction in the number of assembly steps and the reduction in cost can be achieved better.
[0011]
Further, the ceiling panel may be provided in a hollow shape. By adopting such a configuration by blow molding or the like, the weight of the entire ceiling panel can be reduced, and an air layer is formed in the protruding portion to improve heat insulation in a connection area between the ceiling panel and the wall panel. It is possible to do.
[0012]
Further, it is preferable to adopt a configuration in which a packing is provided between the wall panel and the ceiling panel so as to be substantially in the same plane as the inner surface of the wall panel. In such a configuration, in addition to improving the airtightness between the panels, the packing does not protrude greatly from the inner surface of the wall panel, so that it is possible to avoid the accumulation of dirt in the connection area between the ceiling panel and the wall panel. It becomes possible.
