DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type building constructed by combining a plurality of building units.

[0002]

2. Description of the Related Art As shown in FIG. 3, a general building unit 2 includes four pillars 3 at four corners, and a ceiling beam 4 and a floor beam 5 connecting upper and lower ends of these pillars 3 to each other. A ceiling material, a floor material, a wall material, and the like are attached to the frame 6 in advance at a factory, and are formed in a substantially box shape. Then, by combining a plurality of such building units 2, as shown in FIG.
For example, a two-story unit-type building 1 composed of a lower-floor building unit 2A and an upper-floor building unit 2B mounted thereon is built.

[0003] Among such unit-type buildings, those having three or more floors for use in apartment houses, hospitals, hotels, and the like are required to have columns, beams, floors, walls, walls, etc. based on the Building Standard Law.
It is required that a main structural part such as a roof has a fireproof structure having a predetermined fireproof performance. Therefore, in general, the floor material, the ceiling material, and the wall material are covered with a refractory material to meet the above demand.

[0004] As a fireproof structure near the wall material in the apartment house or the like, the wall material is disposed on the side surface of the building unit 10. It has been known that an adjacent building unit provided with is disposed adjacent to each other so that the boundary wall material of each unit is opposed to each other, thereby being erected between the two units. And these building units were arranged up and down, and the boundary wall was joined up and down. In such a unit-type building, since the upper and lower boundary walls are joined by direct joining of the hard boundary wall materials, the joining operation is difficult and the accuracy is poor.
A technique as described in Japanese Patent Publication No. 300140 has been developed.

[0005] The unit-type building according to this technique is a technique in which a soft fire-resistant spacer is interposed between upper and lower boundary walls of a housing unit.

[0006]

By the way, the housing units on both sides are provided with a wall material having a predetermined thickness.
A refractory space is formed between the spaces between the wall materials, that is, between the wall surfaces of both units. In the unit-type building, in order to form a fireproof space between the boundary walls as described above, it suffices that the ends of the boundary wall materials of the upper and lower housing units are joined to each other. However, in the unit-type building of the above publication, the soft spacers interposed between the upper and lower housing unit boundary walls do not join only the ends of the boundary wall material, but the boundary walls of the adjacent housing units. Provided between them. Therefore, there is a problem that the material is wasted, the cost is increased, and the cost is high.

Further, when the upper and lower housing units are combined, the spacer is interposed between them, so that the work is troublesome. Furthermore, since the spacer is a single product, there is a problem that the spacer is easily lost.

[0008] It is an object of the present invention to provide a unit-type building having a fire-resistant material which can be easily made into a fire-resistant structure and is not easily lost, while reducing waste by eliminating waste of materials. .

[0009]

Accordingly, the present invention provides a ceiling beam.
And building unit having a refractory inner wall and refractory flooring which is attached via an associated structure was placed vertically on floor beam, the resistance <br/> fire the inner wall of the upper and lower story building unit across the refractory flooring In a unit building constituting a continuous boundary wall , the refractory floor material of the upper floor building unit has a lower surface thereof.
Almost at the same height as the lower end of the floor beam of the building unit
And within the fireproof of the lower-floor building unit
The upper end of the wall is the upper end of the ceiling beam of the building unit and
It said satellite structure upper end and extends to substantially the same height of, at least one of said refractory inner wall upper surface and attendant structure upper surface of the lower story building unit or the refractory flooring upper floor building unit facing the these A unit-type building characterized in that a soft refractory material is previously attached to the lower surface of the building.

[0010]

According to the present invention, when a unit type building is constructed by combining upper and lower floor building units, a soft refractory material is interposed between them. The soft refractory material is attached to at least one of the upper surface of the fireproof inner wall of the lower-floor building unit and the upper surface of the accompanying structure, or the lower surface of the fireproof inner wall of the upper-floor building unit facing the lower surface, so that the soft refractory material is horizontally
It is not necessary to provide over the refractory inner wall facing, and waste of material is eliminated and cost can be reduced. In addition, since the soft refractory material is attached in advance, the refractory structure can be easily obtained simply by assembling the building unit, and the hard refractory material is not easily lost, thereby achieving the above object.
