Description

  The present invention relates to a frame structure of an apartment house. Specifically, the present invention relates to a frame structure of an apartment house in which a plurality of dwelling units are arranged in the longitudinal direction.

Conventionally, a plate-shaped apartment house in which a plurality of dwelling units are arranged side by side in the longitudinal direction (column direction) is known (see Patent Document 1).
In this plate-shaped apartment house, for example, one dwelling unit is assigned to one span in the longitudinal direction, and all dwelling units are partitioned by load bearing walls. In other words, a load bearing wall extending in the short direction of the building (the direction between the beams) is provided for each span in the longitudinal direction.

  According to this plate-type apartment house, by placing the longitudinal side of the building facing south, the sunlight of each dwelling unit becomes even, so it is possible to prevent unfairness in the sunshine between dwelling units. Since the opening can be provided on the side surface on the north side and the side surface on the south side, the air permeability is excellent. In addition, since the load-bearing wall is provided for each span, it can sufficiently resist the horizontal force in the short direction of the building during an earthquake and has high earthquake resistance.

JP 2011-106245 A

  However, since each dwelling unit is partitioned by a load-bearing wall in the plate-shaped apartment house described above, the dwelling unit cannot be provided using the space for two spans, and it has not been possible to renovate significantly. Therefore, there is a problem that the degree of freedom in planning is reduced.

The reason why it is important to improve the degree of freedom in planning in plate-shaped apartments is as follows.
In plate-shaped apartment houses, the plan for each dwelling unit is often almost the same in order to emphasize economic efficiency and productivity. In this case, the residents of each dwelling unit at the time of completion of the building have the same generation and family structure. As a result, in 20 to 30 years, the resident population will age and the local community may collapse. Therefore, it is important to set a floor plan for each dwelling unit so that it is easy to accept various residents with different generations and family structures.

  In addition, there are cases where it is required to change the use of a part of a building to a public facility or office due to the decrease in the population of the area or the intention of the owner. Therefore, it is desirable to set the partition inside the building to be changeable (skeleton infill).

  An object of this invention is to provide the frame structure of the apartment house which can improve the freedom degree of planning.

  The frame structure of an apartment house according to claim 1 is a frame structure of an apartment house in which a plurality of dwelling units are arranged side by side in the longitudinal direction of the building, and is provided two spans apart in the longitudinal direction of the building. It is characterized by comprising a pair of load bearing walls extending in the short direction and a column provided between the pair of load bearing walls.

  The frame structure of an apartment house according to claim 2 is characterized in that three or more combinations of the pair of bearing walls and pillars are provided on one floor.

According to the present invention, the pair of load bearing walls are provided 2 spans apart, and the pillar is provided between the pair of load bearing walls.
Therefore, since the interval between the load-bearing walls becomes two spans, the degree of freedom in planning can be improved as compared with the conventional case where the interval between the load-bearing walls is one span. That is, by appropriately setting the length of each span, various dwelling units having different areas from small dwelling units to large dwelling units can be provided in combination in a plane and in a three-dimensional manner.

For example, a dwelling unit with a width of 2 spans from the bearing wall to the bearing wall can be provided, or a non-bearing wall is provided on the pillar to construct a door wall, and one span from this door wall to the bearing wall A dwelling unit that is as large as a minute can also be provided.
Even if such a structure is adopted, since the long-term load of the floor slab is supported by the pillar, it is not necessary to increase the thickness of the floor slab. Since it resists, the same level of rigidity as before can be secured.

  In addition, since a pair of bearing walls is provided two spans apart and a column is provided between the pair of bearing walls, when an impact is applied to the upper floor slab, the area of the floor slab that vibrates due to this impact is Larger than Therefore, since the primary natural frequency is lowered, no loud sound is generated in the frequency band that is easily heard by human ears, and the performance of blocking heavy floor impact sound can be improved.

  The frame structure of an apartment house according to claim 3 is characterized in that the pillar is provided at a substantially central position of the pair of load bearing walls.

  The frame structure of an apartment house according to claim 4 is characterized in that the pillar is a flat pillar extending in the short direction of the building.

Here, the flat column is a column in which the long side dimension of the column is twice or more the short side dimension of the column.
According to this invention, since the pillar is a flat pillar extending in the short direction of the building, the space around the pillar can be easily used, and the degree of freedom in layout design is improved.

  The frame structure of an apartment house according to claim 5 is characterized in that a door wall is provided by a non-bearing wall extending from the flat column in the short direction of the building.

  According to this invention, since the non-bearing wall is provided on the flat column, it is possible to secure a large number of dwelling units provided in the building by forming the door wall with the flat column and the non-bearing wall. Moreover, a large dwelling unit can also be provided by removing a non-bearing wall suitably.

  The frame structure of an apartment house according to claim 6 is provided with a core portion including a staircase or an elevator shaft at a predetermined position in the longitudinal direction of the building, and the core portion extends in the longitudinal direction of the building and is a column beam. It has a seismic element consisting of a brace or bearing wall added to.

  According to the present invention, the seismic element composed of braces or bearing walls resists the horizontal force in the longitudinal direction of the building at the time of the earthquake, so there is no need to provide a large cross-sectional beam on the longitudinal side surface of each building. Wide windows can be secured.

  According to the present invention, the pair of load bearing walls are provided 2 spans apart, and the column is provided between the pair of load bearing walls. Therefore, since the interval between the load-bearing walls becomes two spans, the degree of freedom in planning can be improved as compared with the conventional case where the interval between the load-bearing walls is one span. That is, by appropriately adjusting the length of each span, various dwelling units having different areas from small dwelling units to large dwelling units can be provided in combination in a plane and a three-dimensional manner.
