DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-resistant partitioning device, and more particularly, to a fire-resistant partition in which a fire-resistant panel is mounted on a metal column erected between a ceiling rail and a ground rail via an inorganic fire-resistant material. The present invention relates to a partitioning device.

[0002]

2. Description of the Related Art Generally, a fire-resistant partitioning device includes a ceiling rail disposed on a ceiling side, a ground rail disposed on a floor surface opposite to the ceiling rail, and a ceiling rail and a ground rail. And a fireproof panel mounted on the support.

Conventionally, the top rail, the ground rail, and the columns have been made of an inorganic refractory material such as a glass fiber-mixed cement material, and a metal cover has been attached to the surface of the rail to appropriately reinforce it. However, since the mechanical strength of the inorganic refractory material is relatively low, there is a limit to the reinforcement by the metal cover. Particularly, when a tall support is used, there is a problem in strength in the conventional device. there were.

Therefore, it is conceivable to construct a fire-resistant partitioning device by making the rails and the columns themselves made of metal and mounting an inorganic refractory material on their outer surfaces. In this case, the metal strut ensures sufficient mechanical strength for the entire device, but on the other hand, the inorganic refractory material is exposed on the front side, so that the inorganic refractory material is supported during the assembly of the device. When attaching to a fireproof panel, or when attaching a relatively heavy fireproof panel to an inorganic fireproof material, a device is required.

The present invention has been made in view of such a conventional situation, and provides a fire-resistant partitioning device which can secure sufficient strength as the whole device and can easily and surely assemble the device. The purpose is to:

[0006]

A fireproof partitioning device according to the present invention is a fireproof partitioning device in which a fireproof panel is attached to a metal support erected between a ceiling rail and a ground rail via an inorganic fireproof material. In the above, a height-adjustable adjuster base is arranged in the ground rail, a lower end of the support is inserted into the adjuster base via a panel receiving base, and the support is supported by the adjuster base, and the panel is supported by the adjuster base. While supporting the inorganic refractory material at the upper end of the receiving base, the refractory panel is locked by a locking portion provided on the panel receiving base, and the inorganic refractory material disposed on the side surface of the ground rail and attached to the inorganic refractory material.
