Description
本発明は、基礎くい打ち機構にかんするものである。 The present invention relates to a basic striking mechanism.
現在減震機構の必要に迫われている。 Currently, there is an urgent need for a seismic reduction mechanism.
しかし、基礎と杭及び地盤と共に振動という欠点があった。 However, there was a drawback of vibration along with the foundation, pile and ground.
解決しようとする問題点は、地盤と基礎の動きを切り離す点である。 The problem to be solved is to separate the ground and foundation movement.
上記目的を達成するために、本発明は、請求項１にこの改善策として、杭の撓みを用いて基礎の動きを減小して成る事を特徴とする減震くい打ち機構。
杭の径より穴径を大きく掘り杭の下部をコンクリートなどにて固定し、中間部、及び上部の空間に石灰などの弱結合材を充填し、その上に基礎と杭を結合して構成している。
In order to achieve the above-mentioned object, the present invention provides a vibration-reducing pit mechanism according to
The hole diameter is digged larger than the pile diameter, the lower part of the pile is fixed with concrete, etc., the middle part and the upper space are filled with weak binding material such as lime, and the foundation and the pile are combined on it. ing.
上記目的を達成するために、本発明は、請求項２にこの改善策として、杭の撓みを用いて基礎の動きを減小して成る事を特徴とする減震くい打ち機構。
杭の径より穴径を大きく掘り杭の下部をコンクリートなどにて固定し、中間部、及び上部の空間に石灰のどの弱結合材とクション材を充填し、その上に基礎と杭を結合して構成している。
In order to achieve the above-mentioned object, the present invention provides a vibration-reducing pit mechanism according to
The hole diameter is dug larger than the pile diameter, the lower part of the pile is fixed with concrete, etc., the middle and upper spaces are filled with weakly binding material and lime of lime, and the foundation and the pile are joined to it. Is configured.
上記目的を達成するために、本発明は、請求項３にこの改善策として、杭の撓みを用いて基礎の動きを減小して成る事を特徴とする減震くい打ち機構。
杭の径より穴径を大きく掘り杭の下部をコンクリートなどにて固定し、中間部、及び上部の空間に石灰のどの弱結合材とクション材及び小粒子材を充填し、その上に基礎と杭を結合して構成している。
In order to achieve the above object, according to the present invention, as an improvement measure according to
The hole diameter is dug larger than the diameter of the pile, the lower part of the pile is fixed with concrete, etc., and the intermediate and upper spaces are filled with weakly binding material of lime, crushed material and small particle material, and then the foundation and Combining piles.
上記目的を達成するために、本発明は、請求項４にこの改善策として、杭の撓みを用いて基礎の動きを減小して成る事を特徴とする減震くい打ち機構。 In order to achieve the above object, according to the present invention, as an improvement measure of the present invention, a vibration reducing rake mechanism characterized in that the movement of the foundation is reduced by using the deflection of the pile.
杭の径より穴径を大きく掘り穴壁を金属及びコンクリートなどにて成形固定し、掘り穴の下と、杭の下部をコンクリートなどにて固定し、中間部、及び上部の空間に石灰のどの弱結合材を充填し、その上に基礎と杭を結合して構成している。
地震による地盤が動いたとき杭の下部は地面と共震し、上部は弱結合材を破壊し杭の動きに抵抗し震動を抑える。
The hole diameter is larger than the diameter of the pile and the hole wall is molded and fixed with metal or concrete, and the bottom of the hole and the lower part of the pile are fixed with concrete. It is constructed by filling a weak binding material and connecting a foundation and a pile on it.
When the ground moves due to an earthquake, the lower part of the pile co-seismics with the ground, and the upper part destroys the weak binding material to resist the movement of the pile and suppress the vibration.
特に上部に充填する機能材は、単体及び複合して成型してもよく、特にゴムなどわ可能である。又、上部の充填は無くても可能である。 In particular, the functional material to be filled in the upper part may be molded as a single body or a composite material, and particularly rubber or the like can be used. It is also possible without the top filling.
地震による地盤が動いたとき杭の下部は地面と共震し、上部は弱結合材を破壊し杭の動きに抵抗し震動を抑える。即ち減震作用を行う。 When the ground moves due to an earthquake, the lower part of the pile co-seismics with the ground, and the upper part destroys the weak binding material to resist the movement of the pile and suppress the vibration. In other words, it reduces the vibration.
地震による地盤が動いたとき杭の下部は地面と共震し、上部は弱結合材を破壊し杭の動きに抵抗し震動を抑える。即ち減震作用を行う。 When the ground moves due to an earthquake, the lower part of the pile co-seismics with the ground, and the upper part destroys the weak binding material to resist the movement of the pile and suppress the vibration. In other words, it reduces the vibration.
本発明のくい打ち機構は、軟弱地盤に必然的に多く使用されるので、減震効果が取りだせ地震による地盤が動いたとき杭の下部は地面と共震し、上部は弱結合材を破壊し杭の動きに抵抗し震動を抑える利点がある。 Since the pile driving mechanism of the present invention is inevitably used in soft ground, the lower part of the pile co-seismic with the ground and the upper part breaks the weak bond material when the ground is moved by the earthquake due to the seismic reduction effect. There is an advantage that resists the movement of the pile and suppresses the vibration.
本発明のくい打ち機構は、上部は弱結合材とを破壊し杭の動きに抵抗し震動を抑える利点がある。空間に石灰のどの弱結合材とクション材として、ゴムを及び小粒子材として砂利を充填し、その上に基礎と杭を結合して構成している。
ゴムは、微振動を吸収し砂利は、滑り抵抗にて、振動を減少する効果がある。
The pile driving mechanism according to the present invention has an advantage that the upper part breaks the weak binding material, resists the movement of the pile, and suppresses the vibration. The space is filled with lime as a weak binding material and crushed material, rubber and small particle material filled with gravel, and a foundation and a pile are combined on it.
Rubber absorbs minute vibrations, and gravel has the effect of reducing vibrations by slip resistance.
本発明は、減震くい打ち機構で基礎に関する減震で、減震を簡易利用できる。 The present invention is a vibration reduction for the foundation with a vibration reduction pile striking mechanism and can easily use the vibration reduction.
