Description
【0001】[0001]
本考案は、建物の基礎に埋設されるアンカーボルトから、そのアンカーボルト で固定される土台に伝わる振動に関するものである。 The present invention relates to an anchor bolt that is embedded in the foundation of a building. It is related to the vibration transmitted to the base fixed by.
【0002】[0002]
従来、上部構造物等への免震は、ローラや球体を使ったスリップ方式や積層ゴ ム支承を用いた弾性支持方式構造が数多く開発されている。積層ゴム支承には鋼 板とゴムを交互に重ねたもの、高減衰ゴムを使用し鉛プラグを内在させたもの、 また、特開平2−200925号公報の様に、積層ゴム支承と水平方向の相対振 動を吸収する為の弾塑性ダンバーを組み合わせたもの等がある。また実用新案登 録公報にも、アンカーボルトを支承的な免震や制振構造にした実登303615 9号や実登3034049号等がある。 Conventionally, seismic isolation for superstructures, etc. is performed by the slip method using rollers or spheres A large number of elastic support type structures using a bearing have been developed. Steel for laminated rubber bearings Plates and rubbers alternately stacked, high damping rubbers with lead plugs internally, In addition, as disclosed in Japanese Patent Laid-Open No. Hei 2-200925, relative vibration in a horizontal direction relative to a laminated rubber bearing is used. There is a combination of elasto-plastic dampers for absorbing movement. In addition, utility model registration In the official bulletin, the actual bolts with anchor bolts were used as a base isolation and vibration control structure. There are No. 9 and Noboru 3034049.
【0003】[0003]
従来からの技術の内、現在使われている免震構法は弾性支持方式の比率が高く 、積層ゴム支承の一部等は、すでに実用化され利用されてはいるが、しかしそれ らは重量建造物向きであって、一般住宅等の軽量建造物には、設置するのに必要 な面積や価格的な面で適さない。また、鋼材の太さが限定されるアンカーボルト では、支承的な構造にした場合微細な揺れにも反応してしまう欠点がある。 Of the conventional technologies, the seismic isolation method currently used has a high proportion of elastic support methods. Some of the laminated rubber bearings have already been put to practical use, but They are suitable for heavy buildings, and are required for installation in lightweight structures such as ordinary houses. It is not suitable in terms of area and price. Anchor bolts with limited steel thickness Then, there is a drawback in that even if it is a supportive structure, it reacts to a minute shake.
【0004】 また、現在のアンカーボルトの欠点は、地震から発生した水平振動の際に、ア ンカーボルトと土台とが直に激突し強烈な衝撃が上部に伝わってしまう事。それ に地震の上下振動は水平動よりは小さいが破壊力は強大である。現在のアンカー ボルトはその事にも対応していないと云う問題点がある。価格の面でも一般住宅 建設には、安価で簡単に使える、費用対効果が高いものが求められている。[0004] Another drawback of current anchor bolts is that when horizontal vibrations are generated due to an earthquake, The inner bolt and the base collide directly with each other and a strong shock is transmitted to the upper part. It The vertical vibration of the earthquake is smaller than the horizontal motion, but the destructive force is great. Current anchor There is a problem that Bolt does not support that. General housing in terms of price Construction needs to be cheap, easy to use and cost effective.
