Description
本発明は、基礎杭に関するものである。 The present invention relates to a foundation pile.
現在減震機構は軟弱地盤に適してなく、必要に迫われている。 At present, the seismic reduction mechanism is not suitable for soft ground, and is needed.
しかし、軟弱地盤には杭打ちしているが、碁礎と杭及び地盤と共に振動という欠点があった。 However, although it is piled on the soft ground, 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、改善策として、杭の撓みを用いて基礎の動きを地面より減少して成る事を特徴とする減震杭で、杭の径より穴径を大きく堀り、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を設け、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 pile characterized in that the movement of the foundation is reduced from the ground using the deflection of the pile as an improvement measure, and the hole diameter is made larger than the diameter of the pile. It is constructed by digging, fixing the lower part of the pile with concrete, etc., providing lime in the middle and upper space, and joining the foundation and the pile on it.
上記目的を達成するために、本発明は、改善策として、杭の撓みを大きくするために、構築体の基礎下面が横滑りできる基礎を支える杭を分割し、地中深部に杭底部固定体を設け、該杭底部固定体の頭部と上部杭とを嵌合させ、該上部杭の周囲に径が該上部杭の径よりも大きい穴壁を設け、該上部杭と該穴壁との間には地震時に破壊される石灰を設け、該上部杭の頭部にて基礎を固着、保持して成る減震杭打ち機構と該製品。 In order to achieve the above object, as an improvement measure, the present invention divides the pile supporting the foundation on which the lower surface of the foundation can slide sideways to increase the flexure of the pile, and the pile bottom fixed body is formed deep in the ground. Providing the head of the pile bottom fixed body and the upper pile to be fitted, and providing a hole wall having a diameter larger than the diameter of the upper pile around the upper pile, between the upper pile and the hole wall. The quake- damping pile driving mechanism and the product are provided with lime that is destroyed during an earthquake, and the foundation is fixed and held at the head of the upper pile.
又、上記目的を達成するために、本発明は、改善策として、杭の撓みを大きくするために、基礎を支える杭の周囲壁に螺条の又はリング条に凹凸溝を設けて成る減震杭打ち機構と該製品。 In order to achieve the above-mentioned object, the present invention provides an anti-vibration method in which an uneven groove is provided in the peripheral wall of the pile supporting the foundation in the form of a screw or ring as an improvement measure. Pile driving mechanism and the product.
地震による地盤が動いたとき杭の下部は地面と共震し、上部は基礎、構築物の慣性力により杭は曲がり、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 bends due to the inertial force of the foundation and the structure, destroying the weak binding material and resisting the movement of the pile. In other words, it reduces 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。空間に石灰な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、砂を充填し、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、砂は、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 rubber and weak particles such as lime, and rubber and small particle material with gravel and sand, and the foundation and pile are joined together.
Rubber absorbs fine vibration and gravel, and sand has an effect of reducing vibration by slip resistance.
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、特にゴムなどは可能である。 In particular, the functional material filled in the upper portion may be molded as a single body or a composite, and rubber or the like is particularly possible.
以下、本発明の実施の形態を図に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
