Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a plate-shaped house.

[0002]

2. Description of the Related Art In an apartment house, in order to obtain excellent livability, it is important to improve the sunshine, view and openness on the balcony side where the main living room such as a living room or dining room is located. 2. Description of the Related Art Conventionally, there is known a plate-shaped house in which a girder direction is formed by a facing ramen structure surface on the living zone (balcony side) and a ramen structure surface on the common zone side. In such a plate-shaped house, in order to improve the view and openness on the balcony side, it is necessary to increase the size of the sash on the balcony side as much as possible. In order to realize this, there is a method in which the large beam on the balcony side is moved to the tip of the balcony so that it has a reverse beam shape and is also used as a balcony handrail. However, according to this method, there is a problem in that the reverse beam that also serves as the balcony handrail blocks the line of sight from inside the dwelling unit and a good view cannot be secured.

[0003] Therefore, there has been proposed a method of reducing the size of the beams of the large girder forming the surface of the ramen structure on the residential zone side (balcony side) and providing the balcony with a grid-shaped balcony handrail that does not obstruct the view. However, by reducing the beam size of the large beam on the balcony side, the rigidity of the building in the girder direction becomes insufficient, and the deformation of the building during an earthquake becomes large, which tends to cause structural inconvenience.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned prior art, and has good sunshine, view, and openness on the balcony side where a main living room such as a living room and a dining room is arranged. The object is to provide a plate-shaped house having a structure with excellent earthquake resistance.

[0005]

A plate-like house is a form of an apartment house used for a tower-like house, and has a shape in which the girder direction is longer than the beam-to-beam direction.

The present invention can be further configured as follows. (2) Multi-layered small walls will be provided to equalize the deformation of each floor during an earthquake. (3) The multi-story small wall is located between the residential zone side ramen structure surface and the common zone side ramen structure surface, or on these structure surfaces. (4) The multi-layered small wall is located in the wall of the internal stairs or in the space around the unit bath in the dwelling unit. (5) The vibration damping damper is composed of a hysteresis damper, a viscous damper, or a viscoelastic damper.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In each figure, the same reference numerals are used for the same constituent elements, and redundant description will be omitted as appropriate. Figure 1
Is a plan view of the reference floor of the embodiment of the plate-shaped house according to the present invention,
FIG. 2 is a cross-sectional view in the beam-to-beam direction Y on the standard floor, and FIG. 3 is a frame assembly diagram in the girder direction X (common zone side ramen structure surface).

As shown in FIG. 1, the building 1 is a plate-shaped house in which a column direction X is formed by a facing ramen structure surface 2 on the living zone side and a ramen structure surface 3 on the common zone side.
The housing zone side ramen structure surface 2 is constructed by a rigid frame structure in which columns 20 and 20 and beams (large beams) 21 that are upright at a required interval are rigidly joined, and the shared zone side ramen structure surface 3 is a required interval. It is constructed by a rigid frame structure in which columns 30 and 30 standing upright and a beam (large beam) 31 are rigidly joined, and both structural surfaces 2 and 3 face each other forming substantially parallel surfaces. Both structural surfaces 2 and 3 are usually constructed by RC construction or SRC construction.

A floor slab is provided between the housing zone side ramen structure surface 2 and the common zone side ramen structure surface 3, and the housing unit 4
Are formed. A balcony 5 is provided outside the residential zone side ramen structure surface 2, and a shared corridor 6 which is a shared zone is provided outside the shared zone side ramen structure surface 3. A plurality of dwelling units 4 along a common corridor 6 extending in a strip shape
The building 1 has a rectangular planar shape with the girder direction X as the longitudinal direction as a whole. The inter-beam direction Y, which is orthogonal to the column direction X, is constructed by the multi-layer bearing wall 7, and the multi-layer bearing wall 7 forms a boundary wall that partitions each dwelling unit 4.

The beam 21 is formed by a flat beam 21 on the residential zone side frame 2 of the frame. Flat beam 21
2 is a bending member whose cross section has a horizontally long rectangular shape with a beam width w larger than the beam width h. By using the flat beam 21, the opening 23 on the balcony 5 side
The maximum amount of sash can be secured, and the sunshine, view, and openness of the living room on the balcony 5 side can be improved. The flat beam 21 may be a flat plate in which the beam shape does not protrude from the lower surface of the floor slab in order to further improve the view. The structure type of the flat beam 21 is generally RC, but is not particularly limited. When using RC construction, either cast-in-place concrete or precast concrete may be used.

As shown in FIGS. 1 and 3, a seismic damping damper 8 is arranged on the shared zone side rigid frame structure surface 3. The seismic damper 8 has a function of absorbing vibration energy at the time of an earthquake and controlling acceleration and deformation of the building 1. Since the large beam of the residential zone side frame structure 2 is a flat beam 21, the rigidity of the building 1 is lower than that of a normal frame structure. Therefore, the seismic damper 8 is installed on the shared zone side frame structure 3 By providing such a structure, an increase in deformation due to a decrease in rigidity is suppressed. Seismic damper 8
Is disposed on the shared zone side ramen structure surface 3, so that comfortability is not impaired. Further, since the seismic damper 8 can be uniformly arranged in each span and a plurality of layers within the common zone side rigid frame structure 3, the construction is easy and the construction period can be shortened. Of course, it is not necessary to place it on every span / layer.

As the vibration damper 8, a hysteresis damper utilizing the restoring force characteristic of steel or utilizing friction, or a viscous damper such as an oil damper, a viscoelastic damper, or the like can be used.

The illustrated damping damper 8 is an example configured as a hysteresis damper. As shown in FIG. 3, the seismic damper 8 is installed on the columns 30 and 3 of the ramen structure 3 on the common zone side.
It is located in the middle of the span between zero. Further, the seismic control damper 8 is arranged in each span and each layer in the common zone side rigid frame structure 3.

FIG. 4 is a perspective view showing the structure near the vibration damper 8, and FIG. 5A is a front view near the vibration damper 8.
(B) is a bb sectional view of (a). As shown,
The vibration damping damper 8 includes damper fixing portions 80, 80 and a damper portion 81 connected to these damper fixing portions. The damper fixing portions 80, 80 are the upper and lower beams 31, 31.
The protrusions are formed so as to coaxially face each other in the vertical direction. The damper fixing portions 80, 80 are, for example, RC
It is formed by manufacturing. A damper portion 81 is located in the middle of the damper fixing portions 80, 80, and the damper portion 81 is fixed to the damper fixing portions 80, 80. The damper portion 81 is formed to have an H-shaped cross section, for example, the web 8
Extremely mild steel LY-215 is used for 1a. The damper portion 81 is fixed to the base plate 82, and is fixed to the damper fixing portions 80, 80 via the base plate 82 by using fixing means such as bolts and nuts. The periphery of the damper portion 81 is usually covered with an ALC material 83 or the like. Needless to say, the type of damping damper is not limited to this type. It is also possible to use a K-shaped damping brace or the like arranged so as to form an inverted V shape.

Next, the continuous small wall 9 of the present invention will be described. The multi-layered small wall 9 is a planar structural member having a function of equalizing the deformation of each floor during an earthquake. Multi-layered small wall 9
Is a multi-story multi-story structure, is a structure in which bending failure is dominant, precedes bending failure, and is placed at a position where the rigid floor assumption holds. Usually, they are partially arranged in a form orthogonal to the boundary wall, that is, along the girder direction and between spans in the girder direction. The continuous small walls 9 do not necessarily have to be continuous from the lowermost floor to the uppermost floor. Further, it may be provided at one place or a plurality of places on the reference floor.

The structural form of the continuous small wall 9 is not particularly limited. For example, it can be configured by RC manufacturing. FIG. 6 shows a cross-sectional view of a configuration example of the continuous small wall 9. As shown in the figure, the bar arrangement of the multi-layered small wall 9 is a multi-bar structure in the general part (intermediate part), and both ends are provided with an axial direction reinforcing bar 91 and a shear reinforcing bar 92 assuming a column shape to prevent the collapse of concrete. It is desirable to place them.

The multi-story small wall 9 is located between the residential zone side rigid frame structure 2 and the shared zone side rigid frame structure 3 or at these structural faces 2 and 3 so as to be arranged at a position where the rigid floor assumption is established. Preferably. For example, it is preferable that the multi-layered small wall 9 is located in the wall portion of the internal stairs or in the space around the unit bath in the dwelling unit. By using such a wall portion, it is possible to avoid impairing the openness of the dwelling unit space, lowering the degree of freedom in planning, and causing a reduction in the dwelling unit space. There is also a merit that the sound insulation effect can be enhanced.

The analysis condition is shown below with the result of the static three-dimensional elasto-plastic analysis by the Ai distributed load of the 12-story apartment house expressed by the frame diagram. The analytical model is a three-dimensional three-dimensional frame model consisting of columns, beams, beam-column joints, and continuous small walls, and the boundary condition is pin support under each column. The deformation factors to be considered in the analysis are
The columns are bending, shearing, and axial deformation, the beams are bending and shearing, and the beam-column joints are shearing. Modeling of members is
The beam is a model in which the end rigid-plastic spring is arranged on both sides of a wire having elastic bending characteristics, and the multi-layered small wall is an element replacement model represented by two rigid beams and one middle pillar. It is assumed that a rigid plastic spring at the end of the material having a deformation component with respect to the rotation and the axis in the wall is placed. As a comparative example, the one without the multi-layered small wall was compared.

As shown in the graph of FIG. 9, the one with the continuous small wall 9 has a gentler deformation curve than the one without the multiple small wall 9, and the deformation of each floor during the earthquake is uniform. You can see that it has been made.

The embodiment of the present invention has been described above.
The present invention is not limited to the above embodiment,
Various modifications and additions are possible within the scope of the present invention. The plan form of the standard floor of the plate-shaped house is not limited to the single corridor system, but may be the middle corridor system.

[0024]

As described above, according to the plate-shaped house of the present invention, it is possible to improve the sunshine, view and openness on the balcony side where the main living room such as the living room and the dining room is arranged. The increase in deformation due to the decrease in rigidity can be suppressed by the vibration control damper arranged on the joint zone side rigid frame structure surface, and excellent vibration control performance can be exhibited. Since the vibration control damper is arranged on the frame surface of the shared zone side ramen, it has the effect of not impairing habitability.

Further, by providing the multi-layered small wall for uniforming the deformation of each floor at the time of earthquake, the deformation of each floor at the time of earthquake can be made uniform and the effect of the seismic damper can be improved. By arranging the multi-layered small wall in the wall part of the internal stairs or in the space around the unit bath in the dwelling unit, such wall part can be effectively used, and the openness of the dwelling unit space is impaired,
It is possible to avoid lowering the degree of freedom of planning and reducing the space of the dwelling unit.
