Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a building unit. More specifically, the present invention relates to a building unit having an inclined ceiling portion on the gable side or girder side of a ceiling frame, that is, a trapezoidal building unit.

[0002]

[Background Art] As one of building units used in the unit construction method, in order to be able to deal with the north side slope line restriction,
The so-called sloped ceiling part of the ceiling frame,
A trapezoidal building unit is known. For example, Japanese Unexamined Patent Application Publication No. 64-39436 discloses that the ceiling frame on the short side of the building unit has an inclined ceiling portion, and Japanese Patent Laid-Open No. 64-39436 discloses that the ceiling frame on the long side of the building unit has an inclined ceiling portion. No. 2-147737 and Japanese Patent Laid-Open No. 2-1
Japanese Patent Publication No. 47738 is known.

A building unit of this type, for example, a building unit in which an inclined ceiling portion is formed on the short side, has a rectangular floor frame 1 and this floor frame 1 as shown in FIG.
2A and 2B having different heights, which are erected on opposite side edges of the pair, and a ceiling frame 3 which is bridged between the upper ends of the two side frames 2A and 2B.

The floor frame 1 is composed of two long-side lower beams 5 and 6 and a plurality of joists 7 connecting the two long-side lower beams 5 and 6. Wife frame 2A
Two long columns 8A, 9A and these two long columns 8A, 9A
Short side upper beam 10A connecting upper end portions and lower end portions of A
And a short side lower beam 11A. The gable frame 2B is composed of two short columns 8B and 9B, and a short side upper beam 10B and a short side lower beam 11B connecting the upper ends and the lower ends of the two short columns 8B and 9B. It is configured. The ceiling frame 3 is spanned from the upper ends of the long columns 8A and 9A to the upper ends of the short columns 8B and 9B, respectively, and the long columns 8A and 9A are horizontally beamed. 12 and two bending upper beams 14 and 15 having the short columns 8B and 9B on the inclined beam portion 13 and a plurality of small beams 16 connecting the two bending upper beams 14 and 15 to each other. It consists of and.

Conventionally, in manufacturing such a building unit, a floor frame 1 and a gable frame 2 are used in a factory.
A, 2B and the ceiling frame 3 are manufactured separately.
At the time of assembly, after the end frames 2A and 2B are erected on the opposite side edges of the floor frame 1, the ceiling frame 3 is hung between the upper ends of the end frames 2A and 2B, and the end portion of the horizontal beam portion 12 is lifted. The end portions of the slanted beam portion 13 are welded and fixed to the upper ends of the long columns 8A and 9A of the wife frame 2A, and the ends of the inclined beam portion 13 are welded and fixed to the upper ends of the short columns 8B and 9B of the wife frame 2B. That is, the building unit is manufactured by rigidly joining the ceiling frame 3 and the upper ends of the long columns 8A and 9A and the short columns 8B and 9B.

[0006]

In the building unit having the above-described structure, two types of pillars 8 having different lengths, long and short, are used.
Since A, 9A, 8B, and 9B are included, the amount of deflection due to the load varies depending on the length dimension. For example, short column 8
The bending amounts of B and 9B are smaller than the bending amounts of the long columns 8A and 9A even if the same horizontal load is applied. Therefore, when a horizontal load is applied to the frame of the building unit due to an earthquake or a typhoon, the bending amounts of the short columns 8B and 9B are different from the bending amounts of the long columns 8A and 9A. Therefore, these columns 8A and 9A, 8B,
A large load is applied to the rigid joint between 9B and the ceiling frame 3.

An object of the present invention is to provide a building unit including two types of columns, long and short, having different length dimensions, which can improve durability against a load applied to a joint portion of the columns. Especially.
