SOLUTION: In a multiple dwelling house provided with a central corridor put in between a plurality of houses arranged at both sides, columns 70 forming one element of a main frame 60 of one unit including two layers having a lower floor part 11 positioned at the side of the central corridor and a upper floor part 15 positioned at the upper part of the lower floor part 11 and partly exposed at the upper part of the central corridoe, is arranged at both sides of houses 1, 1 between which the central corridor is positioned. That is, since the area ratio of the opening of the central corridor 6 or the like in the part of the multi-story shear wall 61 to the shear wall of one unit including two layers is small, the main frame 60 of two planes of structure can be made and hence, a maisonette type multiple dwelling house can be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a multi-story space formed by a main frame comprising floors, columns and beams, and at least one intermediate floor provided in this space.
The present invention relates to a maisonette-type apartment house that employs a superstructure method and includes a room that is made up of multiple floors in a space.

[0002]

2. Description of the Related Art In a multi-family housing, there is a central corridor type in which a plurality of dwelling units are arranged on both sides of a corridor. Conventionally, when a central corridor is viewed in a vertical section perpendicular to its longitudinal direction, In many cases, the building was a three- or four-story building with both sides or one side of the central corridor and the end side of the dwelling unit opposite the central corridor.

[0003]

SUMMARY OF THE INVENTION In a conventional central corridor type apartment house, in the case of a three-story or four-story building, if a multi-story earthquake-resistant wall is adopted, disadvantages in the strength due to lack of openings in the central corridor and short spans will occur. Disadvantage occurs, and the number of skeletons increases. By the way, in an apartment house in which a space formed by a main frame composed of floors, columns and beams is stacked on a plurality of floors, or in a multi-use building having such an apartment house, two or three layers vertically adjacent to each other A room that forms one space over the other room is generally called a maisonette (or duplex). The problems mentioned above, such as the disadvantages in strength and short span due to the lack of openings in the multi-story shear walls, and the increase in the number of skeletons, were also observed in the case of a maisonette-type apartment house with a central corridor type and a skeleton of one unit per unit. The same is true.

[0004] The disadvantages in the strength and short span due to the above-mentioned lack of openings in the multi-story shear walls increase restrictions on facilities around the central corridor, particularly in the ceiling. In addition, as the number of structural surfaces increases, that is, as the number of pillars increases, the restrictions on the plan also increase.

Accordingly, an object of the present invention is to realize two structures in the form of a corridor, thereby reducing the number of frames, eliminating disadvantages in terms of yield strength and short span, reducing plan restrictions, and restricting ceiling facilities in the corridor. It is an object of the present invention to provide a maisonette-type apartment house that can be reduced.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention according to claim 1 is directed to an apartment house having a central corridor sandwiched between a plurality of dwelling units arranged on both sides. A shape having a lower floor portion located on the side and an upper floor portion located above the lower floor portion and partially facing above the middle corridor, and surrounding a space around the upper and lower floor portions The main frame is formed by one unit of the multi-layer
Pillars, which are one element of the main frame by unit, are arranged on both sides of the dwelling unit across the central corridor to reduce the ratio of the loss of the opening to the multi-story earthquake-resistant wall and construct a maisonette-type apartment house Configuration.

[0007] As described above, according to the first aspect of the present invention, a multi-layer unit having a shape surrounding a space portion formed by a lower floor portion on the side of the middle corridor and an upper floor portion partially facing above the middle corridor. Is a maisonette-type apartment house with a mainframe built by the company, so in the middle corridor style, two columns can be realized by arranging the pillars of the multi-layer 1-unit mainframe on both sides of the dwelling unit sandwiching the middle corridor. The superstructure system using the mainframe of one unit of the multilayer structure reduces the number of frames and is advantageous in structural cost. That is,
The number of pillars and piles can be reduced. Further, in the central corridor, disadvantages of the shear strength of the multi-story shear walls and short spans can be eliminated, and the number of frames as a whole can be reduced. And the constraint of the plan by the pillar type can also be reduced. In addition, restrictions on equipment in the ceiling of the central corridor can be reduced.
