Description

本発明は並目、細目等の頭付ボルトの緩み止めを行う方法である。  The present invention is a method for preventing loosening of head bolts such as coarse and fine.

頭付ボルトの緩み止めの方法としては座金を上部材に固定し、この座金を折り曲げる等の方法によりボルトの頭の回転を阻止するものがあるが、締付けた時の頭の角度によっては確実に回り止めを行うことが困難なこともある。  There is a method to prevent the head bolt from loosening by fixing the washer to the upper member and bending the washer to prevent the bolt head from rotating, but depending on the angle of the head when tightened It may be difficult to prevent rotation.

頭付ボルトをねじ込んだとき、振動等により生じる緩みを確実に、しかも簡単な作業により制止することが必要である。  When the headed bolt is screwed in, it is necessary to securely prevent loosening caused by vibrations and the like and to restrain it by simple work.

頭付ボルトの緩み止めの構造において、頭付ボルト１の頭部上面にボルトのねじ外径と同寸法の円形の罫描線を描き、この線上の１８０°相対する２ケ所の位置よりボルト頭部２を貫通して、その下面（３）より少く深くまで垂直に２本の錐孔（４）を穿孔しておき、頭付ボルトを上部材９のボルト孔１０を通して下部材１２にねじ込んだ後、この２本の錐孔を通して上部材のボルト孔１０の入口角部１１に向って門形釘５を打込み、その釘の両足先端の楔部角の切刃８をそこに喰い込ませて頭付ボルトと上部材は結合されるようにする。In the structure to prevent loosening of the head bolt, a circular ruled line with the same dimensions as the screw outer diameter of the bolt is drawn on the top surface of the head bolt 1, and the bolt head from two positions 180 ° opposite to this line. After drilling two conical holes (4) perpendicularly to the lower surface (3) and penetrating through 2 and screwing the head bolt into the lower member 12 through the bolt hole 10 of the upper member 9 , implanted Mongatakugi 5 towards through this two Kiriana the inlet angle 11 of the bolt hole 10 of the upper member, the head of the cutting edge 8 of the wedge portion angle of both feet tip of the nail by bite therein The attachment bolt and the upper member are combined.

本発明の実施により頭付ボルトを強く締め込んだ後、簡単な方法で確実な緩み止めが可能になる。  According to the present invention, after the head bolt is strongly tightened, it is possible to reliably prevent loosening by a simple method.

本発明の実施形態の一例として、頭付ボルトをねじ込んだ後、その頭部より門形釘を打込んだ状態の縦断面図As an example of an embodiment of the present invention, after screwing a head bolt, a longitudinal sectional view of a state in which a portal nail is driven from the head 図１の平面図Plan view of FIG. 図１の側面図Side view of FIG. 本発明の実施形態の一例として門形釘の正面図Front view of a portal nail as an example of an embodiment of the present invention 図４の平面図Plan view of FIG. 図４の側面図Side view of FIG.

頭付ボルトの緩み止めの構造において、頭付ボルト１の頭部上面にボルトのねじ外径と同寸法の円形の罫描線を描き、この線上の１８０°相対する２ケ所の位置よりボルト頭部２を貫通して、その下面３より少く深くまで垂直に２本の錐孔４を穿孔しておく。  In the structure to prevent loosening of the head bolt, a circular ruled line with the same dimensions as the screw outer diameter of the bolt is drawn on the top surface of the head bolt 1, and the bolt head from two positions 180 ° opposite to this line. Two conical holes 4 are drilled perpendicularly to the lower surface 3 so as to pass through 2.

頭付ボルトを上部材９のボルト孔１０を通して下部材１２にねじ込んだ後、この２本の錐孔を通して上部材のボルト孔１０の入口角部１１に向って門形釘５を打込み、その釘の両足先端の楔部角の切刃８をそこに喰い込ませて頭付ボルトと上部材は結合されるようにする。After the headed bolt is screwed into the lower member 12 through the bolt hole 10 of the upper member 9, the portal nail 5 is driven through the two conical holes toward the entrance corner 11 of the bolt hole 10 of the upper member. The cutting edge 8 of the wedge part corner of both feet is bited into the head bolt so that the head bolt and the upper member are coupled.

門形釘の両足６の形状は、丸棒でも角棒でもよいが錐孔４に軽く圧入される寸法にする必要がある、両足先端の楔部角の切刃８は焼入れされ、上部材のボルト孔の入口角部１１に鋭く切込ませる。  The shape of both legs 6 of the gate-shaped nail may be a round bar or a square bar, but needs to be dimensioned to be lightly press-fitted into the conical hole 4. A sharp cut is made in the entrance corner 11 of the bolt hole.

打込まれる門形釘５は両足６を打込んでいるので互に脱出を阻止しようとするため、容易に振動により脱落する恐れはなく、又頭付ボルトをねじ戻すときは門形釘の門形の下の空間に楔を打込むことにより引抜くことが容易である。Since the gate-shaped nail 5 to be driven is driven by both feet 6, the gate-shaped nail 5 tries to prevent each other from escaping, so there is no risk of falling off easily due to vibration. It can be easily pulled out by driving a wedge into the space under the shape.
