DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to horizontal and vertical building units.
The present invention relates to a unit building configured to be adjacently arranged in a vertical direction .

[0002]

2. Description of the Related Art Conventionally, as a unit building constructed by arranging building units horizontally and vertically adjacent to each other, it is known as a special building
There is one described in JP-A-55-14217. However, as described in JP-B-56-6458, a conventional building unit is composed of a box-shaped frame in which a column, a floor beam, and a ceiling beam are joined, and the floor beam is supported by the floor beam and the ceiling beam is supported. The ceiling material is supported.

[0003]

However, in the prior art, as shown in FIG. 8, while the ceiling material is provided above the lower floor unit, the unit height Hu is limited, so that the ceiling of the living room is limited. The high HR must be as low as HR = Hu-C (C is the distance from the upper surface of the unit to the lower surface of the ceiling material).

The upper floor unit and the lower floor unit are separated by a distance B.
If the building is installed at a height above the building, the building height h can be increased irrespective of the limit of the unit height Hu, but the ceiling height HR of the living room does not change and the dead space [ A + B + C] (A is the floor from the bottom of the unit
( The distance to the upper surface of the face material ). At this time, in order to increase the ceiling height HR of the living room in accordance with the building floor height h, the ceiling material may be provided within the range of the above-mentioned A. Because it is constructed on site, both the construction period and construction cost are disadvantageous.

According to the present invention, the ceiling height of the living room of the unit building is
The purpose is to increase the construction time and cost while shortening it.

[0006]

Means for Solving the Problems The present invention according to claim 1, columns and floor beams and ceiling beams and Ri Na by the floor material is supported on the floor beams of the box-shaped framework member formed by joining, floor beams The building unit with ceiling material above the lower edge of the building and below the floor material
And unit buildings that are arranged vertically adjacent to each other
The ceiling beam of the lower-floor building unit and the upper-floor building unit
Beam reinforcement for placing concrete between the floor beams
Girder units are arranged and configured
It is a thing .

[0007]

[0008]

According to the present invention, the following operations are provided. When building units are constructed by stacking building units up and down, ceiling materials for lower-floor rooms will be provided at the lower end of upper-floor units, and floor materials for lower-floor units and ceiling materials for upper-floor units will be provided. The ceiling height of the living room, which is the distance from the ceiling, can be increased. At this time, since the building units are vertically stacked with the floor material and the ceiling material provided in advance, the ceiling height of the living room can be increased while shortening the construction period and construction cost.

A girder unit is disposed between a ceiling beam of the lower floor unit and a floor beam of the upper floor unit, and an upper floor unit having a ceiling material for a lower floor living room and a lower floor unit having a floor surface material Between the floor unit of the lower floor unit and the ceiling material of the upper floor unit, thereby further increasing the ceiling height of the living room. be able to.
