Here, referring to FIG. 5, the basic operation of the present invention will be described.
The concept will be described. In the figure, reference numeral 11 denotes a pillar portion
A pillar for a general house with a square section housed in 10a
And MM is the central axis of each of the adjacent pillar portions 10a, 10a.
Is a module core. For example, in a dwelling unit of a detached house, the size of the cross section of the pillar 10a is set to be constant, and the dimensions of the furniture and the like are determined in advance in accordance with the inner dimensions La and Lb of the pillar 10a. Commonality of
Can be. On the other hand, in a multi-storey building with middle to high floors,
The dwelling units with the same shape are stacked.
The higher the height of the entire building, the higher
Since the stress applied to the pillar 10a of the
Enlarge the cross-sectional shape of the pillar 10a to reinforce the pillar
Need to be In this case, for each building,
The area and the inner dimension La, Lb between the pillars 10a, 10a
The changed dwelling unit will be prepared, and the pillar 10

To increase the cross-sectional area of the column. For example,
The dwelling unit used for high-rise buildings of 10 stories or more,
Pillar 1 compared to those used for 4-5 story middle-rise buildings
The inner dimensions La and Lb between 0a and 10a are constant,
Since the cross-sectional area of the pillar 10a is large,
The whole unit is larger. That is, in the embodiment, the dwelling unit used in the middle-rise building and the high-rise building is used.
Although the outer dimensions of the set are different,
The legal dimensions La and Lb are always used in any dwelling unit.
It is characterized in that it is constant .

This concept is based on the assumption that the beams 10b, 10c
It is needless to say that the same applies to the case where the cross section is enlarged.

Further, as a technique for reinforcing the dwelling units 10, 10A, not only a method of increasing the cross section of columns and beams but also a method of reinforcing wall thickness, bearing wall and the like can be applied.

Further, as a means for connecting the dwelling units, for example, a method by bolting or the like is applied, but other means may be used as long as the dwelling units can be integrated.

Further, in the illustrated examples shown in FIGS. 1 to 6, the dwelling unit is constituted only by a so-called frame, but inside the dwelling unit, an interior member such as a bus unit, a sanitary unit, and a partition furniture is provided. It is needless to say that a configuration in which is assembled in advance may be adopted.

In the dwelling unit, dimensions such as length, width, height and the like are set within the limits of a truck for transporting from a factory to a site.

Next, the operation of the dwelling unit configured as described above will be described.

As shown in FIG. 1, in order to construct this high-rise building, the reinforced dwelling units 10A and 10B and the dwelling unit 10 are manufactured in a factory or the like, and transported to the site by truck or the like. The dwelling units 10A, 10B and 10 are arranged in three rows and four rows from the first floor.

The dwelling units 10A, 10B, 10
In this arrangement, the strengthened dwelling units 10A and 10B are installed, and the dwelling units 10 are arranged side by side with the enhanced dwelling units 10A and 10B.

Next, the reinforced dwelling units 10A and 10B and the dwelling unit 10
When the units adjacent to each other in front, rear, left and right are fastened while continuously stacking, the middle and high-rise building as shown in FIG. 1 is completed.

For example, as shown in FIG. 6 , the dwelling unit 10 can be lifted by using the reinforced dwelling unit 10B as a table, installing a tower crane 20 thereon, and using the tower crane 20. I do.

This construction is a construction method in which the dwelling units 10A, 10B, and 10 manufactured in the factory are respectively carried to the site and are sequentially stacked on top of each other by using the tower crane 20. Workability can be improved.

In the embodiment, the reinforced dwelling unit 10
A and 10B have ventilation ducts 11 respectively piped therein and supply air ducts connected to these ventilation ducts 11.
Since the ventilation to the dwelling units around the reinforced dwelling units 10A and 10B can be performed by the door 14, there is no need to construct so-called piping facilities on site, and workability on site can be improved.

Further, in the embodiment, as shown in FIG. 5, the widths of the columns and beams are expanded outward of the unit with the inner dimensions La and Lb inside the module core being fixed. Since the structure is such that the cross sections of the columns and beams are increased, in all the dwelling units 10A and 10 constituting the building, it is possible to share common interior parts such as unitized furniture incorporated inside the dwelling unit. There is an advantage that mounting of interior parts does not become inconvenient.

In the embodiment, the dwelling units 10A and 10B with the highest rigidity (strengthened dwelling unit) are stacked at the center of the building, respectively, to form a column-shaped frame with high rigidity. A skeletal structure in which the rigidity of the building is increased with respect to the horizontal force can be obtained. Therefore, the horizontal force applied to the building is transmitted to the four corner frames having the highest rigidity, and the horizontal force is borne at this portion. This does not impose a large burden, and the strength required for the members constituting the dwelling unit 10 can be small, so that an inexpensive building can be constructed as a whole structure.

The various shapes and dimensions of the constituent members shown in the embodiment are merely examples, and can be variously changed based on the design requirements of the building to be applied, and the arrangement of the reinforced dwelling units 10A and 10B. The position is not limited to the embodiment, and various arrangements according to the form of the building can be adopted.

In the embodiment shown in FIGS. 1 to 6,
Although only the frame of the building is schematically illustrated, it is a matter of course that each dwelling unit is provided with a fireproof coating or the like.
