Description

  The present invention relates to a structure of a so-called tri-star type housing complex.

In a housing complex, a so-called tri-star type having a wing portion extending in three directions in plan view is known. Tri-star housing is very efficient in terms of business balance when building large housing. Tristar apartments are also suitable for irregularly shaped sites because they can be rotated according to the shape of the site to ensure a separation distance from the site boundary.
However, in order to improve earthquake resistance, the Tristar type housing complex must be constructed with high strength. In this case, pillars, beams and the like protrude into the room, and the pillar beams on the outer periphery become large. For this reason, there is a problem that when a high-rise house is used, the view is not sufficiently obtained and the merchantability is impaired.
Therefore, in Patent Document 1, a continuous earthquake-resistant wall is arranged in a plane in a triangular shape, and by providing a living space on the outer periphery of the triangular portion, the outer peripheral portion of the living space is configured with small columns and beams, Buildings that can secure large windows on the outer periphery of the living space have been proposed.

JP-A-6-129135

The tri-star type high-rise apartment building has the property of being easily twisted around the central axis extending in the vertical direction due to its structure. This twisting cannot be sufficiently suppressed even if the technique for arranging the above-mentioned continuous earthquake resistant walls in a triangular shape is used.
In order to suppress this twisting, it is generally effective to shorten the span of columns arranged on the outer periphery frame, particularly the outer periphery on the front end side of the wing portion, for example.
On the other hand, in the tri-star type housing complex, there is a problem that it becomes difficult to divide the room of the dwelling unit when the span of the outer column is shortened.
In addition, in a tri-star type housing complex, it is desired to have the best view of the dwelling unit on the tip side of the wing part when selling dwelling units.
In other words, considering the suppression of twisting, it is necessary to minimize the distance between the columns on the front end side of the wing portion. Therefore, the view on the dwelling unit on the front end side of the wing portion is impaired, and the merchantability is reduced.
Accordingly, an object of the present invention is to provide a structure of an apartment house that can easily divide a room of a dwelling unit while suppressing twisting, and that can ensure a view and improve merchandise.

The present invention employs the following means in order to solve the above problems.
That is, the present invention is a structure of an apartment house including a wing portion that protrudes in three directions in plan view, and a plurality of columns arranged at predetermined intervals as a frame on the outer periphery of the wing portion. A pair of first twist-inhibiting columns provided on the same span at least one inside from the tip of the wing portion and formed larger than the pillar disposed at the tip of the wing portion; and the first twist A pair of second torsion suppression columns disposed between the suppression columns at a predetermined interval and formed larger than a column disposed at the tip of the wing portion, and the pair of second torsion suppression columns And a first vibration control device that is attached so as to cross between the two.
In the structure of this apartment house, the pair of first torsion suppressing columns and the pair of second torsion suppressing columns are arranged on the same straight line in the width direction of the wing portion protruding in three directions in plan view. In the same span, which is at least one inside from the tip, a portion having a relatively higher strength than the surroundings can be formed to suppress vibrations of the building, particularly vibrations in the twisting direction. Moreover, the said vibration can be attenuated by the 1st damping device attached between the 2nd torsion suppression pillars.
Thereby, the twist of a building can be suppressed without shortening the span of the pillar in the front-end | tip part of a wing part. Further, it is possible to secure the view at the tip of the wing part and improve the merchantability.

In addition, a plurality of seismic walls arranged annularly in a plan view and the seismic walls adjacent in the circumferential direction are attached to a central portion to which the bases of the wings protruding in three directions are connected. And a second seismic control device.
Thereby, since the earthquake-resistant wall is arranged in an annular shape in plan view, the strength of the central portion is increased, and the vibration of each wing portion can be suppressed by the earthquake-resistant wall arranged in an annular shape. Moreover, the vibration of a building can be attenuated by the 2nd seismic control apparatus provided between the some earthquake-resistant walls arrange | positioned cyclically | annularly. As a result, it is possible to further suppress the occurrence of torsion in the building due to a synergistic effect with the first torsion suppression column, the second torsion suppression column, and the first vibration control device.

Further, at least one of the first vibration control device and the second vibration control device may be a boundary beam type vibration control damper.
Thereby, it can prevent that a 1st, 2nd vibration control apparatus enlarges. As a result, it is possible to improve the degree of freedom in designing the room allocation of the dwelling units.

Moreover, you may provide the seismic isolation apparatus between the lower end of the said pillar, and the foundation.
Thereby, while suppressing the shake by the earthquake of the whole building, it can further suppress that a building is twisted.

  According to the present invention, it is possible to easily divide a room of a dwelling unit while suppressing twisting, and it is possible to secure a view and improve merchantability.

It is a top view of the apartment house in the embodiment of the present invention. It is sectional drawing of the said housing complex, Comprising: (a) is sectional drawing which follows the AA line of FIG. 1, (b) is sectional drawing which follows the BB line of FIG. It is a front view which shows an example of a boundary beam type damper.

Hereinafter, with reference to an accompanying drawing, a form for carrying out a structure of an apartment house by the present invention is explained. However, the present invention is not limited only to this embodiment.
FIG. 1 is a plan view of the apartment house, and FIG. 2 is a cross-sectional view of the apartment house.
The apartment house 1 of this embodiment is a super high-rise apartment house. As shown in FIG. 1, the apartment house 1 includes a plurality of wing parts 2 and a central part 3.

  The wing part 2 is arranged so as to protrude in three directions in plan view. More specifically, the three wing portions 2 are formed so as to protrude radially from the central portion 3. The circumferential angle between adjacent wing portions 2 is substantially the same angle. The wing part 2 has a substantially constant width dimension shorter than the length of the wing part 2 protruding. An end face 6 extending in a direction substantially orthogonal to the direction in which the wing part 2 extends is formed at the tip part 5 of the wing part 2. Here, the “tip portion” refers to a range from the end face 6 to one inner span on the base side.

  Each wing part 2 is provided with the pillar 7 which comprises a frame in those outer peripheral parts. These columns 7 are made of reinforced concrete or the like and are formed to extend in the vertical direction (see FIG. 2). These columns 7 are mainly arranged on the outer peripheral portion of the wing portion 2, and adjacent columns 7 are arranged at a predetermined interval. Of the pillars 7 arranged on the outer peripheral part, the pillars 7 arranged on both sides in the width direction of the wing part 2 are respectively arranged in spans (hereinafter simply referred to as the same span) that are substantially equidistant from the end face 6. Yes. In addition, on the end surface 6 of the distal end portion 5, the pillars 7 are respectively disposed on the center portion in the width direction of the wing portion 2 and on both sides thereof. Between the adjacent pillars 7 arranged on the outer peripheral part, beams 8 constituting the frame are respectively passed.

  The plurality of columns 7 provided on the outer peripheral portion of the wing portion 2 includes a pair of first twist suppression columns 9. These first twist suppression columns 9 are formed in a large size so as to have higher strength than the columns 7 adjacent on the outer periphery. More specifically, the first twist suppression column 9 of the present embodiment has an outer surface area that is the same as that of the other adjacent columns 7 and extends inward in the width direction from the column 7, and has a cross-sectional area. Is formed large.

  The pair of first twist suppression columns 9 are provided in the first same span from the distal end portion 5 of the wing portion 2 toward the base side. In the present embodiment, an example in which the first torsion suppression column 9 is provided in the first same span is shown, but it is only necessary to be provided in the same span at least one inside from the tip portion 5. In other words, it should just be provided in the same span between the one inner side span from the front-end | tip part 5 of the wing part 2, and the span of the most base part side. In this case, in terms of suppressing twisting around the central axis of the building extending in the vertical direction, it is preferable to dispose the first twist suppressing column 9 in the same span on the distal end portion 5 side.

The wing portion 2 further includes a pair of second twist suppression columns 10.
Each of the second twist suppression columns 10 has substantially the same cross-sectional shape as the first twist suppression column 9 in a plan view, and is disposed on the inner side in the width direction of the wing portion 2 than the pair of first twist suppression columns 9. . More specifically, the pair of second twist suppression columns 10 are disposed at a predetermined interval from each other on a straight line connecting the pair of first twist suppression columns 9 disposed in the same span. Further, these second twist suppression columns 10 are disposed at a substantially central portion in the width direction of the wing portion 2. The interval between the second twist suppression columns 10 is shorter than the interval between the first twist suppression column 9 and the second twist suppression column 10. Further, the first twist suppression column 9 and the second twist suppression column 10 are connected via a beam 8.

  A first vibration control device 12 is attached between the second torsion suppression columns 10 to attenuate the vibration of the building applied to the frame 11 including the first torsion suppression column 9 and the second torsion suppression column 10. . Further, a large beam 14 is provided at the center 13 in the width direction of the wing part 2 so as to extend from the base part of the wing part 2 to the second twist suppression column 10. Further, a plurality of small beams 15 extend in a horizontal direction orthogonal to the large beams 14. Here, in the wing portion 2, a service portion such as a corridor is disposed at the center 13 in the width direction of the wing portion 2 in at least one inner span from the distal end portion 5. That is, the 2nd twist suppression pillar 10 and the 1st damping device 12 which were mentioned above will be distribute | arranged to the common part of the apartment house 1, respectively. As the first vibration control device 12 in the present embodiment, a boundary beam type vibration control damper, which will be described in detail later, is used.

  The central portion 3 is a portion that forms around the axial center of the apartment house 1. The central portion 3 is connected to the base portions of the three wing portions 2 described above. The central portion 3 has a core portion 20 formed with higher strength than the surroundings in the vicinity of the center. The core portion 20 includes a plurality of core walls (seismic walls) 21 arranged in an annular shape in plan view, more specifically, three core walls 21. These three core walls 21 are made of reinforced concrete or the like, and are formed by a main plate portion 22 and side wall portions 23 extending inward from both sides in the width direction of the main plate portion 22.

  The core wall 21 is arranged so that the direction orthogonal to the front and back surfaces of each main plate portion 22 faces the intermediate position of the wing portions 2 adjacent in the circumferential direction. Each of these three core walls 21 is formed sufficiently thicker than other surrounding wall portions (not shown). That is, the core wall 21 is bent by the main plate portion 22 and the side wall portion 23 and is formed to be thicker than the other wall portions, so that the core wall 21 is significantly larger than the frame disposed around the core portion 20. The strength has been improved.

  Furthermore, between the adjacent core walls 21, a second vibration control device 24 that attenuates building vibration is provided. These second vibration control devices 24 are also composed of boundary beam type vibration control dampers, similarly to the first vibration control device 12 described above. Moreover, each 2nd damping device 24 is distribute | arranged to the vicinity of the center part of the width direction of the wing part 2 extended in three directions. Note that elevator pits are arranged in an inner region surrounded by the main plate portion and the side wall portion of each core wall 21.

  As shown in FIGS. 2A and 2B, the first vibration control device 12 and the second vibration control device 24 described above are provided on the floor except for the vicinity of the roof 25. By providing the first vibration control device 12 and the second vibration control device 24 in this way, the frame 11 including the first twist suppression column 9 and the second twist suppression column 10 and the core wall 21 are provided. Therefore, it is possible to sufficiently attenuate the vibration of the building. In addition, since the first vibration control device 12 and the second vibration control device 24 are not arranged in the vicinity of the roof 25, a burden is imposed on the roof 25 when the first vibration control device 12 and the second vibration control device 24 operate. Is prevented.

  Moreover, in the apartment house 1 of this embodiment, between the lower end part 26 of the some pillar 7 (including the 1st twist suppression pillar 9), the lower end part 27 of the 2nd twist suppression pillar 10, and the foundation 28. The seismic isolation device 30 is attached to the. As these seismic isolation devices 30, for example, a device provided with a laminated rubber isolator in which rubber and a steel plate are laminated in the vertical direction can be used. By providing these seismic isolation devices 30, further vibration damping effects can be obtained in the first torsion suppression column 9 and the second torsion suppression column 10.

  In the core wall 21 in the present embodiment, the lower end portions 31 are integrated. And between the lower end part 31 of the core wall 21 and the foundation 28, the some seismic isolation apparatus 32 provided with a damper is mounted | worn. By providing these seismic isolation devices 32, a further vibration damping effect can be obtained in the core wall 21.

  A damper that attenuates vibration may be combined with the seismic isolation devices 30 and 32. As this damper, the lead member which connects between lower end part 26,27,31 and the foundation 28 in an up-down direction can be used. Further, the lead member may be disposed by vertically penetrating a rubber isolator. Furthermore, the seismic isolation devices 30 and 32 including the damper may be disposed on the outer periphery of the building, while the seismic isolation devices 30 and 32 not including the damper may be disposed on the inner side of the outer periphery of the building. That is, the seismic isolation devices 30 and 32 having a damper may be combined with the seismic isolation devices 30 and 32 not having a damper, and the seismic isolation devices 30 and 32 having a damper may be arranged at appropriate positions.

FIG. 3 is a front view showing an example of a boundary beam type damper constituting the first vibration control device 12 and the second vibration control device 24.
As described above, the first vibration control device 12 and the second vibration control device 24 in this embodiment are each composed of a boundary beam type damper. Since the basic structures of the first vibration control device 12 and the second vibration control device 24 are the same, only the boundary beam type damper used in the first vibration control device 12 will be described in the following description. 2 Description of the boundary beam type damper used in the control device is omitted.

As shown in FIG. 3, the first vibration control device 12 in the embodiment is used as a short span beam spanned between second torsion suppression columns 10 made of reinforced concrete or the like.
The first vibration control device 12 includes a reinforced concrete 35 that covers a joint portion between the H-section steel 34 and the second torsion suppression column 10. The H-shaped steel 34 includes a member 36 made of a general steel material at both ends, and a mild steel panel 37 disposed at the center in the longitudinal direction. The H-shaped steel 34 has an opening 39 formed in the web 38 in the center in the longitudinal direction, and has the same width and height as the upper and lower flanges 40 on both sides of the opening 39 on the web 38 side. A rib plate (not shown) is provided. Further, the H-shaped steel 34 has a mild steel panel 37 attached to an opening 39 between the rib plates and between the upper and lower flanges 40. The mild steel panel 37 is attached to the opening 39 so that the panel surface coincides with the web surface, and is integrally coupled to the H-shaped steel 34 so as to be rigid by welding or the like.

  The reinforced concrete 35 includes a main reinforcement 41, a stirrup 42, and a concrete 43. The main reinforcing bar 41 is arranged substantially parallel to the H-section steel 34, and the end side arranged on the side opposite to the mild steel panel 37 extends to the column surface of the second twist suppression column 10. In addition, the reinforced concrete 35 is provided so as to wrap around from the boundary portion between the mild steel panel 37 and the member 36 in the H-shaped steel 34 to the joint portion between the second torsion suppression column 10. Thereby, the 1st damping device 12 and the 2nd twist suppression pillar 10 are couple | bonded so that it may become rigid. And since the 1st damping device 12 is comprised as mentioned above, when an earthquake etc. arise, the said mild steel panel 37 raise | generates a shear deformation and absorbs vibration energy.

  Here, in order to absorb the vibration energy by shearing and deforming the mild steel panel 37, it is preferable to form the interval between the second torsion suppression columns 10 as short as possible. By doing in this way, the mild steel panel 37 can be rapidly shear-deformed. The mild steel panel 37 may be formed of a steel material having a lower yield point than the member 36 of the H-shaped steel 34, and is not limited to mild steel. For example, a panel made of extremely mild steel or general steel may be used. In addition, the first vibration control device 12 has been described as an example, but the second vibration control device 24 has the same configuration, and the “second torsion suppression column 10” may be read as “core wall 21”.

  Therefore, according to the structure of the apartment house 1 of this embodiment mentioned above, a pair of 1st twist suppression column 9 and a pair of 2nd twist suppression column 10 are the width direction of the wing part 2 which protrudes in three directions by planar view. Are arranged on the same straight line, so that at least one inner part of the same span from the front end of the wing part 2 forms a part (surface) having a relatively higher strength than the surroundings, particularly vibrations of the building Vibration in the direction can be suppressed. Further, since the first torsion suppression column 10 and the second torsion suppression column 10 have higher strength than the surroundings, the vibration of the building is concentrated on the frame 11 including the first torsion suppression column 9 and the second torsion suppression column 10. However, the vibration of the building can be attenuated by the first vibration control device 12. Thereby, the twist of a building can be suppressed, without shortening the span of the pillar 7 in the front-end | tip part 5 of the wing part 2. FIG. Moreover, the room allocation of the dwelling units can be easily performed, and further, the view at the front end portion 5 of the wing portion 2 can be ensured to improve the merchantability.

  Furthermore, the core wall 21 is annularly arranged in plan view, whereby the strength of the central portion 3 is increased, and the vibration of each wing portion 2 can be suppressed by the annularly arranged core wall 21. Moreover, the vibration of the building added via each core wall 21 can be attenuated by the second vibration control device 24 provided between the plurality of core walls 21 arranged in an annular shape. As a result, it is possible to further prevent the building from being twisted due to a synergistic effect with the first torsion suppression column 9, the second torsion suppression column 10, and the first vibration control device 12.

Further, by using a boundary beam type damper for the first vibration control device 12 and the second vibration control device 24, it is possible to prevent the first vibration control device 12 and the second vibration control device 24 from becoming large. As a result, it is possible to improve the degree of freedom in designing the room allocation of the dwelling units.
In addition, since the seismic isolation devices 30 and 32 are provided between the lower ends 26, 27, and 31 and the foundation 28, it is possible to suppress shaking of the entire building due to an earthquake and further suppress the twisting of the building. it can.

For example, the case where a boundary beam type damper is used as the first vibration control device 12 and the second vibration control device 24 has been described, but various types of vibration control devices such as a brace type, a wall type, and a stud type may be used. Good. Further, the first vibration control device 12 and the second vibration control device 24 may be different types of vibration control devices. Also, different types of seismic control devices may be mixed and used in the plurality of first vibration control devices 12 and the plurality of second vibration control devices 24.

In each wing portion 2, the first twist suppression column 9 may be omitted and only the second twist suppression column 10 may be provided.
Moreover, in the said embodiment, although the case where the 1st damping device 12 and the seismic isolation devices 30 and 32 were provided was demonstrated, you may make it provide suitably as needed.
