DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped apartment house which has a short depth and is connected in tandem.

[0002]

2. Description of the Related Art As shown in FIG. 12, a seismic frame of a plate-like apartment house having a short depth and connected in a row in a row has a door boundary wall 1 in a tension direction α, and a column structure in a girder direction β. It is a ramen frame 2 composed of beams.

[0003] In such a plate-shaped apartment house, due to architectural planning,
This is because it is desired that only the gap direction α be an opening, and the column / beam cross section in the row direction β be as small as possible.

[0004]

From the viewpoint of earthquake resistance, a large horizontal strength can be expected in the tension direction α because the frame is mainly composed of a shear wall, and the shaking during an earthquake is small. In addition, even when the wall thickness is increased to improve safety, the influence on the living space is small.

On the other hand, since the beam direction β is a pure ramen, it is generally expected that the toughness is higher than the proof strength, and the vibration during an earthquake is large. Therefore, increasing the cross section of columns and beams to improve safety and reduce shaking will reduce the area of the only opening as a house, which is not preferable in a construction plan.

As means for improving the seismic resistance in the girder direction β, dampers for absorbing vibration energy are incorporated, and a passive vibration control device, which is a system for absorbing vibration, is incorporated in a rigid frame. It is conceivable to reduce earthquake input and sway without increasing the column / beam cross section.

However, if the vibration damping device is provided separately from and separate from the ramen frame, bending deformation occurs and the vibration damping effect is significantly reduced. As in the case of increasing the cross-section, the opening area is reduced, which is not preferable in the architectural planning.

On the other hand, it is possible to provide an independent vibration control frame that does not cause bending deformation so that it can be separated from the rigid frame and provided independently. However, such an independent frame has a large vertical axial rigidity. And a pulling reaction force is required, resulting in an uneconomical or impossible design.

An object of the present invention is to provide a vibration-damping plate-shaped apartment house which can solve the disadvantages of the conventional example and improve seismic performance without reducing the opening area and using an inexpensive structure. It is in.

[0010]

Means for Solving the Problems In order to achieve the above object, the present invention firstly provides a frame structure mainly composed of a seismic wall for a door boundary wall in a tension direction and a rigid frame composed of columns and beams in a girder direction.
Depth short, in the plate-shaped housing complex of tandem rent, to incorporate the vibration control device, the vibration control Plane a Plane to incorporate this vibration control device, and a location separate from the Longitudinal noodles Frames
Outside the surface of the ramen frame, and provided by utilizing the rigidity of the door boundary wall by connecting the end of the vibration control wall to the door boundary wall. Thirdly, to provide two or three or more floors of multi-family dwellings, and thirdly, to arrange flat dwelling dwelling units with short depth and tandem on both sides of the damping structure It is an abstract.

According to the first aspect of the present invention, since the rigidity of the door boundary wall is used to incorporate the vibration damping device in order to prevent bending deformation, independent control is possible even in a place separated from the girder frame structure. It can be incorporated without providing a seismic frame, and there is no danger of reducing the area of the opening in the girder frame structure.

According to the second aspect of the present invention, in addition to the above-mentioned function, the damping structure is provided for every two or three or more floors of the apartment house. Displacement occurs and the vibration control effect can be exhibited.

[0013] Even if the shaft rigidity is ensured, since the pull-out resistance is small in a normal foundation, it is necessary to take measures to generate a large pull-out force on the foundation. It becomes expensive and uneconomical. According to the third aspect of the present invention, by disposing the dwelling units on both sides of the damping structure surface, the pulling force of the foundation can be reduced by its own weight.

[0014]

Embodiments of the present invention will be described below in detail. 1 and 2 are plan views showing a first embodiment and a second embodiment, respectively, of a vibration damping plate-shaped apartment house of the present invention.

FIG. 1 is a plan view of a reference floor of an apartment house in a single corridor, and FIG. 2 is a plan view of a reference floor of an apartment house of two houses and one EV (elevator). 16
As in the conventional example shown in FIG. 1, in the span direction α, the door boundary wall 1 is a frame mainly composed of an earthquake-resistant wall, and in the girder direction β is a rigid frame 2 composed of columns and beams. In the figure, reference numeral 20 denotes a stair, and reference numeral 21 denotes an elevator.

[0016] to the present invention incorporates a vibration control apparatus, the vibration control Plane 3, before as a place that is separate from the Longitudinal ramen Frame 2
It was provided outside the construction of the girder-column frame and utilizing the rigidity of the door border wall 1.

As a vibration damping device to be incorporated into the vibration damping structure 3, a passive vibration damping device which incorporates dampers for absorbing vibration energy and absorbs vibration is preferable. Honeycomb damper system that incorporates a nest-type damper to absorb vibration energy, and a super-durable oil damper 22 that is integrated with the building framework 22
A high damping system or the like that absorbs vibration (see FIGS. 4 to 7) can be used.

Further, as shown in FIG. 3, the vibration control surface 3 is provided between two wings in the case of four doors, and between three wings in the case of six doors as shown in FIG. There can be various choices, such as installation, eight-door installation between four-door ridges, and 16-door installation between two- and eight-door ridges.

As shown in FIGS. 4 to 7, the seismic control structure 3 may have a large truss-like configuration extending over two or three or more floors of an apartment house.

Further, when the damping structure 3 is provided so as to extend over a plurality of floors, if the floor is not divided as shown in FIG. As shown, a slit 5 is formed in the floor 4 to cut off the edge between the floor 4 and the damping structure surface 3.

Although dwelling units are arranged on both sides of the damping structure 3, the pulling force of the foundation can be reduced by its own weight.

FIG. 9 to FIG. 11 show further application examples of the present invention, and various examples such as an increase in length, an increase in height, a ring, and a block configuration type with a plurality of buildings can be considered.

[0023]

As described above, the vibration-damping plate-shaped apartment house of the present invention has a short depth, and when connected in tandem, improves the seismic performance without reducing the opening area.
Moreover, the vibration control device can be incorporated without providing an independent vibration control frame, and the structure can be inexpensive.
