Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a metal fitting for a steel ceiling frame.

[0002]

2. Description of the Related Art In general, a ceiling is connected by a hanging tree between a hanging tree support passed between beams and a field edge to which a ceiling panel is attached, and a peripheral edge of the ceiling panel is provided by 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 board, 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.

[0003] For this reason, the wooden beam is framed into a rectangular frame to form a panel, and the ceiling panels are connected to construct a ceiling.
It has been proposed to partition with a partition panel.
It is known that such a ceiling panel is hung on a beam with a ceiling hanging metal fitting to form a ceiling (see Japanese Patent Laid-Open No. 6-193188, which is the application of the applicant).

On the other hand, when a ceiling panel is used to form the ceiling,
At the periphery of the independent pillar, a gap having a width corresponding to the thickness of the independent pillar and a length corresponding to the length of the ceiling panel is generated. Therefore, when the partition panel is erected along the independent pillar, as described above, The partition panel cannot be fixed due to the gap. For this reason, the applicant has proposed a ceiling structure in which two attachment plates are provided on a wooden cross member of a ceiling panel so as to sandwich an independent pillar, and a partition panel is fixed to the attachment plates (Japanese Patent Laid-Open No. 6- 193185).

[0005]

However, since the pair of ceiling panels arranged along the independent pillars are separated from each other by an interval corresponding to the thickness of the independent pillars, these ceiling panels are connected via the ceiling hanging metal fittings. It is not possible to hang it on the beam while connecting it, and the side of the wooden crosspiece that forms the frame is separated from the independent column and is only cantilevered by the ceiling hanging metal fittings. Therefore, in the independent pillar,
In addition to the disconnection of the ceiling panel connection, the strength of the ceiling is reduced, and the wooden beams at the free ends along the independent columns hang down due to the weight of the ceiling panel, and the height of the ceiling panel is adjusted when the partition panel is installed. There was a problem that it would be difficult.

For the purpose of making the ceiling incombustible and improving the strength of the ceiling groundwork, the applicant of the present invention has filed Japanese Patent Application Laid-Open No. 6-240802.
As described in the publication, it is also proposed that a steel ceiling frame is formed by frame-forming a steel material into a rectangular shape, and the steel ceiling frame is hung on a beam with a ceiling hanging bracket to construct a ceiling. , The point corresponding to the independent pillar is not described.

The present invention has been made in view of the above problems, and a pair of steel ceiling frames arranged along the independent columns or adjacent steel members of the steel ceiling frames can be simply connected. (EN) Provided is a steel ceiling frame connecting fitting which can be integrated.

[0008]

In order to achieve the above-mentioned object, the present invention is a metal fitting for connecting a runner field edge and a field edge or a field edge and a field edge of a steel ceiling frame,
A lower horizontal piece, a pair of left and right vertical pieces bent upward from the lower horizontal piece and having a height corresponding to the runner edge or the height of the edge of the steel ceiling frame, and these vertical pieces. Each of them is bent outwards and consists of a pair of left and right upper horizontal pieces of a runner field edge of the steel ceiling frame or a length exceeding the width of the field edge. These lower horizontal piece, vertical piece and upper horizontal piece are made of steel. It is characterized in that the end portion of the upper horizontal piece can be bent along the runner field or the other surface of the runner field along the runner field or the three fields of the field frame.
