Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a building unit and can be used for a unit type building and the like.

[0002]

BACKGROUND ART In recent years, unit-type buildings have been constructed in which living rooms and the like that make up a building are manufactured as building units in a factory, and these building units are transported to the site for construction. The building unit is configured to include a floor panel, a ceiling panel, a pillar erected between the floor panel and the ceiling panel, a wall panel, and the like.

The floor panel is constructed by arranging a plurality of joists at equal intervals on a floor frame in which long-side beams and short-side beams are assembled in a square shape, and further arranging a floor material on the upper surface. . On the other hand, the ceiling panel is configured by a plurality of small beams straddling a ceiling frame in which long side beams and short side beams are assembled in a square shape, and a ceiling surface material is stretched on the lower surface.

[0004]

In the conventional floor panel,
Since multiple joists were hung on the floor frame at equal intervals, when a heavy kitchen unit, piano, bookshelf, etc. is placed on the floor panel, it is not possible to sufficiently support the load of these heavy objects. There were things.

Therefore, an object of the present invention is to provide a floor structure of a building unit that can arbitrarily support loads of heavy objects.

[0006]

The first invention of the present invention is 4
A floor structure of a building unit in which two beams have a square frame frame and a plurality of joists are directly bridged between a pair of opposing beams, and the joists are adjacent to each other. And at least one of the intervals between adjacent joists, and the portion on which the heavy load is placed is shorter than the other intervals.

[0007] In prior Kiyuka structure, it said joists, whether the spacing between spacing and adjacent joists of the beam adjacent this joist is what percentage, depending on the heavy object is placed on the floor,
It is determined that the load bearing of such a heavy object is sufficient. That is, the interval between the parts on which heavy objects are placed is short.

A floor structure of a building unit according to a second aspect of the present invention is characterized in that, in the first aspect, the at least one interval is approximately half of the other intervals.

[0009]

[0010]

[0011]

[0012]

According to the present invention, at least one of the intervals between the joists and the beams adjacent to the joists and the intervals between the adjacent joists in the portion of the floor on which the heavy load is placed is more than that of the other intervals. The weight can be shortened, and the ratio of the number of joists in the portion on which the heavy load is placed is increased as compared with other portions, so that the load of the placed heavy load can be sufficiently supported.

EXAMPLE A floor structure of a building unit 11 according to a first example of the present invention will be described with reference to FIGS. The building unit 11 includes a floor panel 12, a ceiling panel 13, four columns 14 erected between the floor panel 12 and the ceiling panel 13, a wall panel (not shown), and the like. Is.

As shown in FIG. 1, the floor panel 12 comprises a floor frame 15 and a floor surface member (not shown) stretched on the upper surface of the floor frame 15. The floor frame 15 is
The long-side beam 16 and the short-side beams 17A and 17B are assembled in a square shape, and a plurality of them are provided between the long-side beams 16 facing each other.
Ninth nine joists 18A-18I are hung over. On the other hand, the ceiling panel 13 is composed of a ceiling frame 19 and a ceiling surface member (not shown) stretched over the lower surface of the ceiling frame 19. The ceiling frame 19 includes long side beams 16 and short side beams.
17 and 17 are formed in a square shape, and a plurality of small beams 21 are bridged between the long side beams 16 facing each other.

As shown in FIG. 2, in the floor panel 12, the distance h between the short beam 17A and the first joist 18A, the distance h between the first joist 18A and the second joist 18B, The distance h between the second joist 18B and the third joist 18C and the third h
The interval h between the joist 18C and the fourth joist 18D is different from the other intervals H. That is, the fourth joist 18D to the ninth joist
The interval H between adjacent joists 18D to 18I up to 18I and the interval H between the other short-side beam 17B and the ninth joist 18I are the same interval H, but the interval h is half of this interval H. ing.

The second, fourth, fifth to ninth joists 18B, 18
When D, 18E to 18I are arranged at regular H intervals, the first
The joist 18A is located between the short-side beam 17A and the second joist 18B, and the third joist 18C.
Is placed between the second joist 18B and the fourth joist 18D.

In the unit type building constructed including the building unit 11, the first to third joists are provided.
A heavy object, such as a piano 22, is placed on 18A to 18C. The floor structure of the building unit 11 of this embodiment can be provided as follows. That is, in the production of the building unit 11 in the factory, when assembling the floor panel 12,
The second, fourth, fifth to ninth joists 18B, 18D, 18E to 18I
Are placed at regular equal intervals and the first joists 18
A is placed in the middle between one short-side beam 17A and the second joist 18B, and the third joist 18C is placed in the middle of the second joist 18B and the fourth joist 18D.

According to the floor structure of the building unit 11 according to the above-mentioned embodiment, the distance h between the short beam 17A and the first joist 18A depending on the load of the heavy object, and the first joist 18A Second
The distance h between this joist 18B, the distance h between this second joist 18B and the third joist 18C, and this third joist 18C and the fourth joist
The distance h to 18D is shorter than the other distances H. Therefore, the first to third parts of the portion where heavy objects such as the piano 22 are placed.
Since the ratio of joists 18A to 18C is higher than the other parts, the load of heavy objects placed can be sufficiently supported.

Further, according to the above embodiment, the second, fourth, fifth to ninth joists 18B, 18D, 18E to 18I are arranged at equal intervals as in the conventional case, and the first joists are arranged. The joist 18A is arranged between one short-side beam 17A and the second joist 18B, and the third joist 18C is the second joist 18B and the fourth joist 18
By arranging the building unit 11 in the middle of D, the building unit 11 of this embodiment can be obtained, so that the building unit 11 can be easily manufactured.

EFFECTS OF THE INVENTION According to the floor structure of a building unit according to the present invention, depending on the load of a heavy object , a heavy object can be selected from among the joist, the interval between the joist and the adjacent beam, and the interval between the adjacent joists . But
At least one spacing rests shorter than the other interval
Therefore, it is possible to arbitrarily support the load support of heavy objects.
