[0003]

However, in the ceiling panel mounting structure of the unit room of the above-mentioned conventional structure, the ceiling fixing metal clip must be mounted and operated from the back side of the ceiling panel, and the side wall panel and When the clearance between the ceiling panel and the bearing wall is small, there is a problem that the operation is troublesome and the assembling work efficiency is poor.

Further, this decrease in work efficiency is exhibited not only when the unit room is assembled but also when the ceiling panel and the side wall panel are detached for remodeling. In particular, when the installation of the unit room is limited to the three-sided wall due to the change of the regulations of the Ministerial Ordinance, the above problem becomes remarkable. Furthermore, since a silicone rubber-based caulking agent is filled and sealed between the side wall panel and the ceiling panel, and a sealing work step with this caulking agent is also required, the problem that the number of work steps increases was there.

The present invention has been proposed in view of the above problems, and the ceiling panel can be easily attached / detached from the inside of the room so that the assembly can be firmly fixed in a short time, and the side wall panel and the ceiling panel can be fixed. It is an object of the present invention to provide a ceiling panel mounting structure in a unit room in which sealing work between spaces can be omitted.

[0006]

In order to achieve the above object, a ceiling panel mounting structure in a unit room according to the present invention has a connecting member attached to an outer peripheral portion of the ceiling panel. A peripheral edge portion of the ceiling panel is placed on the upper end portion of the wall panel that has a substantially S-shaped connecting piece that hangs downward from the outer end portion, and has a brim edge portion that projects outward at the upper end portion, It is characterized in that the brim portion of the wall panel is detachably hooked to a substantially S-shaped connecting piece.

Further, the mounting portion of the connecting member to the ceiling panel and the substantially S-shaped connecting piece extending from the connecting member are formed of a hard member and abut on the upper end portion of the side wall panel of the mounting portion to the ceiling panel. Another feature is that the portion is formed of a soft member, and the seal member between the ceiling panel and the side wall panel is formed of the soft member.

[0008]

In the mounting structure of the ceiling panel in the unit room of the present invention, first, the connector is fixed to the peripheral portion of the ceiling panel. Next, when the side wall panel is erected and the brim portion formed at the upper end of the side wall panel is fitted with the substantially S-shaped coupling piece of the coupling tool, the ceiling panel is firmly attached to the upper portion of the side wall panel. It is fixed and the ceiling panel is assembled.

At the same time, in the case where the portion of the connector that abuts on the upper end of the side wall panel is formed of a soft member, the ceiling panel and the wall panel are sealed by the soft member. When removing the ceiling panel by reforming, etc., push up the ceiling panel from the inside of the unit room and release the fitting of the approximately S-shaped connecting piece of the connecting tool from the flange edge of the upper end of the side wall panel. The ceiling panel can then be easily removed from the upper part of the side wall panel.
