Description

【０００１】
【発明の属する技術分野】
本発明は、２層に１台の制震装置を設置した集合住宅の制震装置取付構造に関する。
【０００２】
【従来の技術】
柱・梁架構内へ高減衰オイルダンパを設置する従来の例を図４、５、６に示す。
【０００３】
図４の例では、柱・梁架構と耐震要素としての逆Ｖ型ブレース１３の間に制震装置１を介在させている。
【０００４】
図５の例は柱・梁架構とＮ階の梁６とＮ＋１階の梁１２より立設した、または垂下させたフレーム同志の間に制震装置１を介在させて、耐震要素としてのモーメント抵抗フレームを構成した場合である。
【０００５】
図６の例では、柱・梁架構と耐震要素としての鉄筋コンクリート耐震壁との間に、制震装置１を介在させている。
【０００６】
【発明が解決しようとする課題】
一般に住宅建造物の階高は、事務所等の建造物に比べて階高が低い。一方、地震力による建造物の変形は、建造物が片持ち梁のような挙動をとる。従って制震装置を充分働かせるだけの変形量が得られないという問題点があった。即ち前述の従来方法による制震装置の設置構造では、充分な制震効果が得られなかった。
【０００７】
本発明はこの点に鑑み、２層に１台の制震装置を設置した集合住宅の制震装置取着構造を提供する。
【０００８】
【課題を解決するための手段】
本発明の集合住宅の制震装置取付構造は、集合住宅の廊下と住戸の境に位置する廊下境壁を、開口部を除いて鉄筋コンクリート造または鉄骨ラチス造とし、前記廊下境壁を柱から切り離して柱と廊下境壁との間に間隙を設け、前記廊下境壁をＮ階では梁に剛接して立ち上げ、Ｎ＋２階では梁に剛接して立ち下げ、Ｎ＋１階の床高さの梁を構面を外して設け、Ｎ＋１階の床高さで、制震装置を介して前記Ｎ階から立ち上げた廊下境壁と前記Ｎ＋２階から立ち下げた廊下境壁とを接合してあることを特徴とするものである。
制震装置としては、オイルダンパまたは弾塑性ダンパー等が利用される。
【０００９】
集合住宅等の建造物の階高は一般に低く、地震力による１層分の変形は、事務所の変形に比較して小さい。従って従来のように１層毎に制震装置を設けても効率がよくない。本発明のように、１層おきに２層に１台の制震装置を設置すれば、制震装置に作用する地震時の変形は２層分と大きくなり、大きな制震効果が期待できる。更に制震装置の設置台数を削減できる。
【００１０】
【発明の実施の形態】
以下図面に基づいて本発明の集合住宅の制震装置取付構造を説明する。
【００１１】
図１は集合住宅の平面図の一例で制震装置１の取付構面２の位置を示す。制震装置１は、廊下３と住戸との境に位置する廊下境壁４に設置すれば、共有スペースに制震装置１が設置できるために、制震装置１の保守点検に便利である。また、廊下境壁４及び住戸間に位置する住戸境壁５は、遮音性を確保するため鉄筋コンクリート壁となることが多く、制震装置１に必要な耐震要素としての剛性が確保しやすい。
【００１２】
図２は２層に１台の制震装置１を配置した例であり、Ｎ階の梁６に鉄筋コンクリート壁７を剛接して立ち上げ、Ｎ＋２階の床の梁８に剛接した鉄筋コンクリート壁９を立ち下ろし、Ｎ＋１階の床高さでこれ等の鉄筋コンクリート壁７、９を制震装置１を介して接合した制震装置構面図である。この際、鉄筋コンクリート壁７、９は柱１０とは接続が切れており、間隙１１が設けてある。
【００１３】
図３は、図２の立断面図であり、Ｎ＋１階の床高さの梁１２は該構面を外してある。
【００１４】
制震装置としては、オイルダンパや弾塑性ダンパが応用される。
【００１５】
また本発明は必ずしも集合住宅に限らず、間取りの多い低層の建造物に応用可能なことは勿論である。
【００１６】
【発明の効果】
集合住宅のような低層の建造物で、地震時の変形が小さい場合、２層に１台の制震装置を設置して、２層分の変形を得て制震装置を作動することにより、効率的に大きな効果が期待できる。また、共有スペースとなる廊下側の廊下境壁に制震装置を設置するため、制震装置の保守点検が容易である。
【００１７】
また、廊下境壁は、遮音性を与えるため鉄筋コンクリート造とすることが多いが、制震装置に必要な耐震要素としての剛性が確保しやすい。

BACKGROUND OF THE INVENTION
The present invention relates to a vibration control device mounting structure for an apartment house in which one vibration control device is installed in two layers.
[0002]
[Prior art]
Conventional examples of installing a high-damping oil damper in a column / beam frame are shown in FIGS.
[0003]
In the example of FIG. 4, the vibration control device 1 is interposed between a column / beam frame and an inverted V-type brace 13 as a seismic element.
[0004]
In the example of FIG. 5, moment resistance as a seismic element is provided by interposing a damping device 1 between columns or beams, an N-th floor beam 6, and an N + 1 floor beam 12 erected or suspended. This is a case where a frame is configured.
[0005]
In the example of FIG. 6, the vibration control device 1 is interposed between a column / beam frame and a reinforced concrete earthquake resistant wall as an earthquake resistant element.
[0006]
[Problems to be solved by the invention]
In general, the floor height of a residential building is lower than that of a building such as an office. On the other hand, when a building is deformed by seismic force, the building behaves like a cantilever. Therefore, there is a problem that a deformation amount sufficient to make the vibration control device work sufficiently cannot be obtained. That is, with the installation structure of the vibration control device according to the conventional method described above, a sufficient vibration control effect could not be obtained.
[0007]
In view of this point, the present invention provides a vibration control device mounting structure for an apartment house in which one vibration control device is installed in two layers.
[0008]
[Means for Solving the Problems]
The structure for mounting a vibration control device for an apartment house according to the present invention is such that the hallway wall located at the boundary between the hallway and the dwelling unit of the apartment house is made of reinforced concrete or steel lattice except for the opening, and the hallway wall is separated from the pillar. A gap is provided between the pillar and the corridor boundary wall, and the corridor boundary wall is raised in rigid contact with the beam on the Nth floor, and is suspended rigidly against the beam on the N + 2th floor. The structure is removed, and the floor height of the ( N + 1) floor is joined to the corridor wall raised from the N floor and the hallway wall lowered from the N + 2 floor via a vibration control device. It is a feature.
As the vibration control device, an oil damper or an elasto-plastic damper is used.
[0009]
The floor height of buildings such as apartment buildings is generally low, and the deformation of one layer due to seismic force is small compared to the deformation of the office. Therefore, it is not efficient even if a vibration control device is provided for each layer as in the prior art. If one seismic control device is installed in every two layers as in the present invention, the deformation at the time of the earthquake acting on the seismic control device becomes as large as two layers, and a great seismic control effect can be expected. Furthermore, the number of installed seismic control devices can be reduced.
[0010]
