Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apartment house suitable for increasing the degree of freedom of a floor plan in order to meet the diversifying needs of customers.

[0002]

2. Description of the Related Art An apartment house, commonly called an apartment in Japan, is a building in which a plurality of houses are assembled to form one building, and is usually made of reinforced concrete or steel reinforced concrete. By the way, in recent years, with the background of diversification of customer's sense of values and consciousness toward housing and improvement of living standard, condominiums with a uniform floor plan are gradually disliked. However, in order to meet such needs, in order to realize a floor plan with high flexibility at the time of new construction, the design and construction of the condominium will have to be considerably complicated, complicated, and sophisticated, which will increase costs. Connecting is inevitable. Further, for the same reason, there is a problem that a considerable cost is required even when performing so-called renewal in which the existing floor plan is changed.

Therefore, the applicant of the present invention considered applying a flat plate structure without a beam shape projecting to the lower surface side of the slab on each floor to such an apartment house. As shown in FIG. 8, in the housing complex 1, the frame is orthogonal to the boundary wall 3 from the boundary wall 3 made up of earthquake-resistant walls that partition each dwelling unit 2 and the floor slab 4 of the flat plate structure on each floor. It has a ramen structure in the vertical plane. In such an apartment house 1, the floor slab 4 on each floor has a flat plate structure, and the height from the floor to the ceiling of each dwelling unit 2 is constant at any position, so that a beam type is formed in each dwelling unit 2. It is possible to arrange the partition wall at an arbitrary position without providing a notch for escaping. This makes it possible to increase the flexibility of the floor plan during new construction to meet the diversifying needs of customers and to perform so-called renewal to change the existing floor plan at low cost. .

[0004]

However, the conventional housing complex as described above has the following problems. In the flat-plate structure housing complex 1, the boundary walls 3 are formed of earthquake-resistant walls in order to enhance the earthquake resistance. In the case of such a configuration, in the horizontal direction, rigidity / proof strength in a direction parallel to the boundary wall 3 is secured, but as compared with this, rigidity in a direction orthogonal to this becomes low. Therefore, it is possible to increase the rigidity in this direction by providing an earthquake-resistant wall extending in a direction orthogonal to the boundary wall 3, but in a normal apartment house, the wall orthogonal to the boundary wall 3 is not provided. It is necessary to provide openings such as windows and entrances, and it is difficult to arrange earthquake resistant walls with sufficient bearing capacity. For this reason, the flat plate structure housing complex 1 has a problem that the earthquake resistance in the direction orthogonal to the direction parallel to the boundary wall 3 is lower than that in the direction parallel to the boundary wall 3.

For this reason, in particular, when the housing unit 1 is formed into a substantially rectangular shape in a plan view and the dwelling units 2, 2, ...
Seismic resistance in the longitudinal direction is significantly reduced. Further, if the housing complex 1 is made to have middle and high rises, the above problem becomes more remarkable. Therefore, the flat plate structure cannot be applied to the middle- and high-rise condominiums, and it is difficult to increase the flexibility of the floor plan.

The present invention has been made in consideration of the above points, and it is possible to secure a sufficient seismic performance even in a middle- and high-rise apartment house and to have a high degree of freedom in a floor plan. The purpose is to provide a housing complex where
