Description

本考案は、束石と束柱とを簡易に連結することができると共に、束石に連結された束柱の抜けを確実に防止する束柱の支持装置に関する。   The present invention relates to a support device for a bundle pillar that can easily connect the bundle pillar and the bundle pillar and reliably prevent the bundle pillar connected to the bundle stone from coming off.

従来の束柱における支持構造は、束柱の下端に平ほぞを削り出し、該平ほぞを束石に凹設した掘削孔に嵌入するものであるため、前記平ほぞの加工に手間を要する上に、風雨に曝される束石の上では柱の下端から浸入する雨水などが前記平ほぞを腐食し、束柱の寿命が短命であった。
設置する際も土間や基礎などの連結は乏しく、大きな力が作用した場合に、束石がずれたり、前記束柱の平ほぞが欠損してしまう欠点があった。
そこで、本出願人は、束石と該束石上に位置決めされる束柱の支持構造を開発し、実用新案登録出願をした（特許文献１を参照）。
上記実用新案登録出願は、束柱の支持面に浸入する雨水などの水切りを達成する束石と、束柱下端の平ほぞ加工に代えて孔加工による掘削孔を前記束柱の下端に凹設することによって、耐水性の心棒で束柱と束石とを簡易に接合すると共に、長命化を達成する束柱の支持構造を提供するものである。
登録実用新案第３０１７７９５号公報 In the conventional support structure for a bundle pillar, a flat tenon is cut out at the lower end of the bundle pillar, and the flat tenon is inserted into an excavation hole recessed in the bundle stone. In addition, on the boulders exposed to wind and rain, rainwater entering from the lower end of the pillars corroded the flat tenon, and the life of the bundle pillars was short.
Even when installed, the connection between the soil and the foundation is poor, and when a large force is applied, there is a drawback that the boulders are displaced or the flat tenon of the bundle pillar is lost.
Therefore, the present applicant has developed a support structure for a bund stone and a bunch column positioned on the bund stone, and filed a utility model registration application (see Patent Document 1).
In the utility model registration application, a boulder that achieves drainage of rainwater or the like entering the support surface of the bundle column and a drilling hole formed by drilling instead of a flat tenon at the bottom of the bundle column are recessed in the lower end of the bundle column. By doing so, a bundle pillar and a boulder are simply joined with a water-resistant mandrel, and a support structure for the bundle pillar that achieves a long life is provided.
Registered Utility Model No. 3017795

次に、本考案の束柱の支持装置の使用動作について、以下図面に基づいて説明する。
図５に示すように、まず、束石Ａを設置する基礎コンクリートＢの位置にはアンカーボルトＣと該アンカーボルトＣに螺合したナットＤを一緒に埋設する。
対象とする束石Ａには、あらかじめ上下対向する個所にリング状カッターによりグリップアンカー９の直径と略同径の円形の接合穴をそれぞれに穿孔しておく。
また、束柱Ｅの下面には、心棒４の免震体２及び逆止栓７が嵌合される円形の掘削孔を形成しておく。
なお、前記束石Ａの接合穴は、リング状カッターにより円筒形に所定深さまで切削し、中央の円柱部分を打撃により切除することにより形成される。
前記束石Ａの接合穴が形成されたら、図５の断面図に示すように、始めに、前記束石Ａの下端の接合穴にアンカーボルトＣのグリップアンカー９を差し込み、束石Ａを前記グリップアンカー９により基礎コンクリートＢに固定する。 Next, the operation of using the bundle column support device of the present invention will be described with reference to the drawings.
As shown in FIG. 5, first, an anchor bolt C and a nut D screwed to the anchor bolt C are embedded together at the position of the foundation concrete B where the bundling stone A is installed.
In the target boulder A, circular joint holes having a diameter substantially the same as the diameter of the grip anchor 9 are previously drilled in a portion facing the top and bottom in advance by a ring-shaped cutter.
In addition, a circular excavation hole into which the seismic isolation body 2 of the mandrel 4 and the check plug 7 are fitted is formed on the lower surface of the bundle column E.
The joint hole of the bundle stone A is formed by cutting a cylindrical shape to a predetermined depth by a ring-shaped cutter and cutting the central column portion by striking.
When the joint hole of the bundle stone A is formed, as shown in the sectional view of FIG. 5, first, the grip anchor 9 of the anchor bolt C is inserted into the joint hole at the lower end of the bundle stone A, and the bundle stone A is inserted into the joint stone A. Fix to the foundation concrete B with the grip anchor 9.

次に、前記束石Ａの上端の接合穴に心棒４の下端をグリップアンカー９により差し込み、前記グリップアンカー９により心棒４の免震体２及び逆止栓７を束石Ａに固定する。
そして、前記束石Ａから突出している前記免震体２及び逆止栓７に位置合わせを行いながら、束柱Ｅ下面の掘削孔を前記免震体２及び逆止栓７に差し込み、最終的には束柱Ｅの頂面を叩き、逆止栓７の円環刃６を束柱Ｅに食い込ませるようにして挿入固定することによって、束柱Ｅが束石Ａから抜けるのを防止する。
なお、束石Ａと束柱Ｅの連結部に防振ゴムマット１４を挟み込むと、束石Ａと束柱Ｅに外部から強い力が加わった時に、ゴムの柔軟性が防振力を増すことになる。 Next, the lower end of the mandrel 4 is inserted into the joint hole at the upper end of the bundle stone A by the grip anchor 9, and the seismic isolation body 2 and the check plug 7 of the mandrel 4 are fixed to the bundle stone A by the grip anchor 9.
Then, while aligning the seismic isolation body 2 and the check plug 7 protruding from the bundling stone A, the excavation hole on the lower surface of the bundle column E is inserted into the seismic isolation body 2 and the check plug 7, and finally In this case, the top surface of the bundle pillar E is hit, and the annular blade 6 of the check stopper 7 is inserted and fixed so as to bite into the bundle pillar E, thereby preventing the bundle pillar E from coming out of the bundle stone A.
In addition, when the vibration isolating rubber mat 14 is sandwiched between the connecting portions of the bundle stone A and the bundle pillar E, the flexibility of the rubber increases the vibration damping force when a strong force is applied to the bundle stone A and the bundle pillar E from the outside. Become.
