DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof frame made of steel for roofing.

[0002]

2. Description of the Related Art In general, a ceiling is connected by a hanging tree between a hanging tree receiver passed between beams and a field edge to which a ceiling panel is attached, and a peripheral edge of the ceiling panel is provided at a peripheral edge provided on a partition panel. Is fixed. In the case of such a ceiling structure, a hanging tree receiver is provided for each room partitioned by the partition panel,
The construction of the ceiling plate, the ridge, the hanging tree, and the surroundings has to be performed, so that not only a lot of work time is required but also the cost is increased.

For this reason, Japanese Unexamined Patent Publication No.
As described in Japanese Patent Publication No. 193188, it has been proposed that a wooden beam is framed into a rectangular frame to form a panel, and this ceiling panel is hung on a beam with a ceiling hanging bracket to form a ceiling, and then partitioned by a partition panel. ing. It is known that when a ceiling is formed by using the above-described ceiling panel, the same applies to a roof-down portion (see Japanese Patent Application Laid-Open No. 6-200586 filed by the applicant).

[0004]

However, in the case where the above-mentioned ceiling panel is suspended by the ceiling hanging bracket to construct the roofing section, prior to the installation of the ceiling panel, the roof panel is located near the wall (below the slope). It is necessary to fix a stop that can contact one side of the ceiling panel arranged on the inner wall frame. However, there is a problem that the operation becomes complicated.

[0005] For the purpose of making the ceiling non-flammable and improving the strength of the foundation under the ceiling, the applicant has disclosed in Japanese Patent Laid-Open No. 6-240802.
As described in the official gazette, it has also been proposed to construct a ceiling by forming a steel ceiling frame by framing a steel material into a rectangular shape and fixing the steel ceiling frame to a beam with the above-described ceiling hanging bracket. However, even if such a steel ceiling frame is used in place of the above-mentioned ceiling panel, it has a similar problem because it requires a stop according to the inclination of the roofing beam.

The present invention has been made in view of the above problems, and provides a roofing steel ceiling frame in which a roofing portion can be easily constructed.
