DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for making a frame of a unit building a fire-resistant structure.

[0002]

BACKGROUND ART When a unit-type building constructed by combining a plurality of building units exceeds a certain height or is used for an apartment, etc., the framework of the unit-type building is legally covered with fireproof coating. It must be covered with a material and have a fireproof structure.

[0003] For this reason, it takes a lot of labor and time to individually cover and fix a fire-resistant coating material on each skeleton of a unit-type building. For this reason, each building is constructed at the construction site of the unit-type building. When the units are arranged at predetermined positions, for example, it is desirable to adopt a structure in which the frames of the building units that are vertically adjacent to each other are continuously coated with the same fireproof coating material, and these frames are collectively fireproofed.

[0004]

However, in order to continuously coat the frameworks of adjacent building units with the same fire-resistant coating material, if the entire coating operation is performed as an on-site operation at a construction site, the on-site operation will be difficult. This requires a lot of labor and time, and this is contrary to the purpose of a unit-type building, which aims to increase the work rate in the factory and reduce the work rate in the field to increase work efficiency. Cannot achieve its original purpose.

[0005] An object of the present invention is to perform most of the work for continuously covering the frames of adjacent building units with the same fireproof covering material in a factory, and to reduce the work to be performed at the construction site of the unit-type building. It is an object of the present invention to provide a fireproof structure for a unit-type building, which can increase the work efficiency of the work of covering with a covering material.

[0006]

According to the present invention, there is provided a fireproof covering material for continuously covering the frameworks of adjacent building units. The fireproof covering material has flexibility, and one end side has a framework of one building unit. And the other end is extended to this skeleton so as to cover the skeleton of the other building unit.

[0007] The building unit may be provided with another refractory material covering the skeleton thereof, and an end of the refractory coating material may be joined to the refractory material.

The building unit is vertically joined, the skeleton is a lower beam of the upper building unit and an upper beam of the lower building unit, and the refractory material covers the upper surface of the lower beam. The fireproof covering material may be a continuous floor material, and the fireproof covering material may continuously cover from a side surface of the upper beam to a side surface of the lower beam, and may be joined to a bottom surface of the fireproof floor material.

In the above, the flexible fire-resistant coating material is made of, for example, rock wool, ceramic fiber or the like.

In the present invention, since the refractory coating material has flexibility and one end is fixed to one building unit, this fixing is performed in a factory and the other end is fixed to the building unit. Can be stored. Then, at the construction site of the unit-type building, after the other building unit is arranged next to this one building unit, the other end is extended to the skeleton side of the other building unit, and the frame is fixed to this skeleton. can do. For this reason, the work of continuously covering the frameworks of the adjacently arranged building units with the same fire-resistant coating material can be performed with less work on the construction site, and most of the work can be completed at the factory. Efficiency is improved.
