Description of the Related Art Conventionally, when a fireproof partition is constructed in an RC structure or an SRC structure, after the partition is constructed in order to make the partition channel attached to the upper or lower part of the partition a fireproof structure, A thick refractory material such as rock wool is adhesively coated on the exposed surfaces of the partition channels attached to the upper and lower portions of the partition, or a liquid material such as rock wool is sprayed and solidified on the exposed surfaces of the partition channels. A rock wool coating layer was formed, thereby imparting fire resistance to the partition channel.

[0003] However, in the above-mentioned conventional example, after the partition is once completed, the exposed surface of the partition channel must be subjected to a fireproof process, and there has been a problem that the processing operation is complicated and the construction cost is increased.

Further, when the exposed surface of the channel is coated with a refractory material after the partition is constructed using the channel, there are problems such as a decrease in fire resistance performance and a drop of the coating material.

[0007] The refractory partition channel according to the present invention comprises:
This is a completely new technology that has been developed in view of the above-mentioned many problems in the related art. In particular, when a partition channel is produced in a factory or the like, whether the partition channel is formed using a special steel material having fire resistance in advance. Alternatively, a completely new structure of the partition channel technology, in which a refractory paint is pre-applied to the outer surface of the partition channel or the outer surface of the partition channel is pre-coated with a sheet-like refractory material. To provide.
