Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room unit with a ceiling in which a ceiling panel is attached to an upper part of a wall panel, and more particularly, a room unit with a ceiling suitable for use in a room portion of a unit building to which a wall construction method is applied Regarding

[0002]

2. Description of the Related Art In order to increase the industrial production rate of a building, a room unit by a wall-type construction method is conventionally known, as described in, for example, Japanese Patent Publication No. 58-30978. The room unit by the wall-type construction method is constructed by erection of wall panels on the side edge portions of the floor panel, and is manufactured at a factory in advance and then constructed and assembled at a construction site to form a unit building. The assembly is performed by first installing the lower-floor room unit on the foundation, and then installing the upper-floor room unit on top of each installed lower-floor room unit.

By the way, since the above-mentioned conventional room unit is not provided with a ceiling in units, the installation work of the ceiling panel is carried out locally, and the electrical work of the ceiling and the construction work are naturally carried out locally. The number of local construction man-hours for the overall ceiling work was large. In order to improve this situation, Japanese Patent Application No. 3-335 filed by the applicant of the present application
As described in No. 012, a room unit is proposed in which a wall panel is installed upright on a side edge portion of a floor panel in advance in a factory, and a ceiling panel is attached to an upper portion of the wall panel. .

[0004]

However, the ceiling panel is not for supporting a wind load, unlike the wall panel or the roof panel, and for the load load of people or equipment such as the floor panel. It is also structurally weak because it is not intended to support the ceiling.Therefore, when the room unit with a ceiling according to the above application is transported to the construction site, the ceiling between the floor panel center part and the ceiling panel center part It is necessary to temporarily install the columns that support the load of the panel to ensure transportation safety. However, it is not preferable that such a temporary column be present in the central portion of the room unit because it interferes with the work of building the room unit and the work of carrying in the equipment. Also, it is complicated to install or remove the temporary support columns.

The present invention has been made under such a background, and an object thereof is to provide a ceiling-mounted room unit capable of ensuring transportation safety without the aid of temporary columns.

[0006]

In order to solve the above-mentioned problems, in a room unit with a ceiling according to a first aspect of the present invention, the ceiling panel is composed of a ceiling frame and a ceiling panel adhered to the ceiling frame. Of the pair of frame members arranged on the outermost side in the longitudinal direction constituting the ceiling frame, at least one frame member is formed of shaped steel.

[0007]

According to the above construction, at least one of the frame members (ceiling beams) arranged on the outermost side in the longitudinal direction is shaped steel, so that the ceiling structure surface can be formed without increasing the volume. It can be further strengthened and transportation safety can be improved. Therefore, it is not necessary to install a temporary support column during transportation, and it is possible to smoothly and swiftly carry out the work of construction inside the room unit and the work of carrying in the equipment. In the case of a U-shaped room unit in which wall panels are erected on three side edges of the floor panel, the wall panel is installed above the side edges of the floor panel on which the wall panels are not erected. Since the frame material is structurally the weakest, shaped steel should be applied to the frame material at this location.
