Description

【0001】
【発明の属する技術分野】
本発明は、主として建築物の布基礎と土台及び束石と木製もしくは金属製の束の間に免震支持具を挟み込んだ際の免震支持具の免震効果を高める免震支持方法及びその方法に使用される免震補助具に関するものである。
【0002】
【従来の技術】
従来の建築用免震支持方法として、特開平8−232500号公報に記載されるように、木造家屋(鉄骨製の家屋を含む)のコンクリート製の布基礎及び束石の上に直接木製もしくは金属製の土台を敷設すると、布基礎及び束石に接触している土台や束が腐食するので、これを防止するために布基礎と土台の間に、約1m間隔で合成ゴム等の材料からなる基礎受け板を敷き、基礎部分と土台部分とを基礎部分に垂直に埋設されたアンカーボルトで締めることで固定することによって免震効果を発揮するとされる発明が公知である。
【0003】
【発明が解決しようとする課題】
しかしながら、この従来の工法では、免震効果を発揮するために合成ゴム等の基礎受け板を布基礎及び束石の間に挟み込んだとしても、コンクリート製の基礎部分に埋め込み若しくは取り付けられているアンカーボルトで土台部分と基礎部分がしっかり固定され、アンカーボルトに大きな剪断力が作用するだけであって、アンカーボルトをきつく締め付けることで免震効果はほとんど無くなってしまい免震効果は期待できないものであり、締め付けが甘い場合は、軽微な振動に対しては効果が、大きな振動や揺れに対しては、基礎部分と土台部分が外れて家屋が倒壊する危険性があった。
【0004】
【発明の目的】
本発明は、上記の課題を解決し、地震、台風による衝撃を緩和し、大きな揺れの振動を吸収できる免震支持方法及び建築用免震補助具を提供することを目的とするものである。
【0005】
【課題を解決するための手段】
本発明に係る建築用免震支持方法は、一般住宅のコンクリート製の基礎Aと木製もしくは金属製の土台Bとの間にゴム、合成樹脂、金属、合成樹脂と金属の複合からなる免震支持具Cを適当な間隔に挟み込み、免震支持具と免震支持具の間より換気を行うねこ土台工法もしくは基礎パッキン工法であって、基礎部分と土台部分とを基礎部分に垂直に埋設されたアンカーボルトDで締めることで固定する際、ナットと土台の間に二枚のワッシャー等に挟まれたバネやゴム等の弾性変形可能な免震補助具を介在させることにより、基礎と土台の間に挟み込んだ免震支持具が自在変形し振動を吸収できるようにしたことを特徴とするするものである。
【0006】
【発明の作用】
基礎と土台を固定するために締めるナットと土台の間に免震補助具を介在させたことによって、従来のようにナットで免震支持具を締め過ぎることがなくなり、免震支持具が自在に動き基礎からの振動を吸収でき、土台部分への振動の伝達が小さくなる。
【0007】
【発明の実施の形態】
本発明の実施の形態を図面について具体的に説明する。

図1、4において、Aは、一般住宅のコンクリート製の基礎、Bは、木製もしくは金属製の土台、Cは、合成樹脂、金属、合成樹脂と金属の複合からなる免震支持具、Dは、基礎部分と土台部分とを固定するために使用される基礎部分に垂直に埋設されたアンカーボルトであって、従来はこのアンカーボルトDに直接ナットEをワッシャーを介して締めつけていたものであるが、このワッシャーの代わりに後述する免震補助具を使用したことが本発明の要旨である。
【0009】
図2、3において、1は、本発明方法に使用される免震補助具であって、中央に孔21を穿った二枚のワッシャーに相当する円盤2、2の間にバネ3を介在させた構造となっており、土台BとナットEの間にこの免震補助具1を介在させて締めつけることによって本発明方法による免震支持が行われるものである。

【0011】
【発明の効果】
以上述べたごとく、本発明に係る建築用免震支持方法によれば、免震支持具と免震支持具の間より換気を行うねこ土台工法もしくは基礎パッキン工法において、基礎部分と土台部分とを基礎部分に垂直に埋設されたアンカーボルトで締めることで固定する際、ナットと土台の間に二枚のワッシャー等に挟まれたバネやゴム等の弾性変形可能な免震補助具を介在させることにより、基礎と土台の間に挟み込んだ免震支持具が自在変形し振動を吸収できるようにしたものであるから、横の震動のみならず縦の震動に対して従来の免震支持方法では殆ど奏し得なかった免震支持具の免震効果を充分奏し得るようになったもので、一般住宅の免震支持方法としては画期的な方法といえるものであり、また、この方法に使用される免震補助具も新規な発明といえるものである。

BACKGROUND OF THE INVENTION
The present invention mainly relates to a seismic isolation support method and method for enhancing the seismic isolation effect of the seismic isolation support when the seismic isolation support is sandwiched between a fabric foundation and foundation of a building and a bunch of stones and a wooden or metal bundle. It is about seismic isolation aids used.
[0002]
[Prior art]
As a conventional seismic isolation support method for buildings, as described in Japanese Patent Application Laid-Open No. 8-232500, wooden or metal directly on a concrete cloth foundation and bund stone of a wooden house (including a steel frame house) When a base made of metal is laid, the base and bundle in contact with the fabric foundation and the boulders are corroded. To prevent this, the fabric foundation and the foundation are made of a material such as synthetic rubber at an interval of about 1 m. An invention is known in which a base support plate is laid, and the base portion and the base portion are fixed by fastening with anchor bolts embedded in the base portion perpendicularly, thereby exhibiting a seismic isolation effect.
[0003]
[Problems to be solved by the invention]
However, in this conventional method, even if a base plate made of synthetic rubber or the like is sandwiched between a fabric foundation and a boulder stone in order to exhibit a seismic isolation effect, the anchor is embedded or attached to the concrete base portion. The base part and the foundation part are firmly fixed with the bolt, and only a large shearing force acts on the anchor bolt. By tightening the anchor bolt tightly, the seismic isolation effect is almost lost and the seismic isolation effect cannot be expected. When the tightening is weak, it is effective for slight vibrations, and for large vibrations and shakings, there is a risk that the foundation part and the base part may come off and the house collapses.
[0004]
OBJECT OF THE INVENTION
An object of the present invention is to solve the above-mentioned problems, to provide a seismic isolation support method and a building seismic isolation assisting tool that can mitigate impacts caused by earthquakes and typhoons, and can absorb large vibrations.
[0005]
[Means for Solving the Problems]
The seismic isolation support method for building according to the present invention is a seismic isolation support comprising a rubber, a synthetic resin, a metal, a composite of a synthetic resin and a metal between a concrete foundation A and a wooden or metal base B of a general house. Cat foundation method or foundation packing method that sandwiches tool C at appropriate intervals and ventilates between seismic isolation support and seismic isolation support, and the foundation part and foundation part are embedded vertically in the foundation part When fixing by fastening with anchor bolts D, an elastically deformable seismic isolation tool such as a spring or rubber sandwiched between two washers and the like is interposed between the nut and the base, so The seismic isolation support tool sandwiched between the two can be freely deformed to absorb vibrations.
[0006]
[Effects of the Invention]
By installing the seismic isolation aid between the nut and the base to be fastened to fix the foundation and the base, it is not necessary to overtighten the base isolation support with the nut as before, and the seismic isolation support is free It can absorb the vibration from the moving foundation and the transmission of the vibration to the base part becomes small.
[0007]

【The invention's effect】
As described above, according to the seismic isolation support method for buildings according to the present invention, in the cat foundation method or the foundation packing method in which ventilation is performed between the seismic isolation support and the seismic isolation support, the foundation portion and the foundation portion are When fixing by fastening with anchor bolts vertically embedded in the foundation part, an elastically deformable seismic isolation tool such as a spring or rubber sandwiched between two washers, etc. is interposed between the nut and the base. Because the seismic isolation support sandwiched between the foundation and the base can be freely deformed to absorb vibrations, most conventional seismic isolation support methods are not limited to horizontal vibrations but vertical vibrations. The seismic isolation tool that was not able to perform was able to fully exhibit the seismic isolation effect, and it can be said to be an epoch-making method as a seismic isolation support method for ordinary houses. New seismic isolation aids One in which it can be said that.
