[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an underfloor structure of an apartment house.
[0002]
[Prior art]
Conventionally, as one form of the underfloor structure of an apartment house, a plurality of reverse beams are projected upward on a floor slab that divides each floor, and a floor is formed by horizontally extending floor materials on the reverse beams By doing so, there is one in which a multipurpose space under the floor is formed between the flooring and the floor slab.
[0003]
[Problems to be solved by the invention]
However, the above-described underfloor structure has the following problems.
[0004]
(1) The reverse beam method in which a reverse beam is provided on the floor slab is relatively expensive because it forms an unnecessarily large underfloor storage space and also has a useless underfloor storage space.
[0005]
(2) In the reverse beam method, the height of each floor is increased by about 500 mm to 600 mm. Therefore, it is difficult to secure the number of floors and the floor area by the shade regulation and the advanced oblique line regulation.
[0006]
(3) Since the underfloor storage space is formed by providing the reverse beam, the height of each floor is increased and the number of floors is restricted, so that the number of apartment houses is restricted.
[0007]
(4) Since the storage space under the floor is large, there may be inconveniences such as requiring installation of a fire detector in response to the application of the Fire Service Act.
[0008]
(5) The space (residence space) above the storage space under the floor is not effectively utilized, and each room is arranged in a plane, so the living space is narrowed, giving a tight impression.
[0009]
[Means for Solving the Problems]
Therefore, in the present invention, in a vertical hierarchy of Housing formed by partitions into a plurality of layers by floor slab, by bulging a portion of the floor slab of the storey above downward to form a concave-shaped multipurpose space forming part Along with this, a part of the floor slab in the lower layer is bulged downward to form a concave multipurpose space forming portion, and the multipurpose space forming portion in the upper and lower layers is arranged in a zigzag shape in the left-right direction , A single side fixed structure in which one side of the bottom of the multipurpose space forming portion is fixed to at least a small beam portion which is a beam portion, and a loft is formed above the multipurpose space forming portion, while a part of the multipurpose space forming portion is formed. The boundary between the small beam part and the floor part to be formed can be used as a chair, and a desk is arranged at a position corresponding to the boundary part and between the loft and the multipurpose space forming part. Of the floor located near the border Between minutes and loft there is provided a floor structure of a collective housing, characterized in that it spanned the ladder.
