Description

本発明は、一つの被締結部材と他の被締結部材を締結するための継手に関するものであり、特に変位吸収機能を備えた継手に関するものである。   The present invention relates to a joint for fastening one member to be fastened and another member to be fastened, and particularly relates to a joint having a displacement absorbing function.

この明細書でいう「変位吸収」の機能を、例えばシールドトンネルのセグメント組み立てに用いる継手について説明する。
ひとつの被締結部材であるセグメントと、他の被締結部材であるセグメントはボルトで締結するのが一般的である。
ところが締結後に地震や地盤のひずみの外力によって継手面が強制的に目開きが生じる場合がある。
その際に、通常のボルトであると引っ張り破断したり、あるいは継手金具が破損する可能性がある。
そこでこのような変位を吸収する機能を備えた継手として、例えば図１４に示すように、弾性ワッシャーａを用いる方法がある。
これはセグメントに取付けた継手金具ｂどうしを通常のボルトｃ、ナットｄで締結する際に、弾性係数が剛質材よりも非常に小さい、すなわち圧縮変形しやすい材料によって肉厚の円筒を弾性ワッシャーａとして使用する構造である。
このような構造であると、セグメントどうしが目開きを生じる場合に、この弾性ワッシャーａが弾性変形することにより変位を吸収し、ボルトｃや継手金具ｂに過度の応力が生じないという効果がある。

特開平１１−１８２１８５ The function of “displacement absorption” in this specification will be described for a joint used for assembling a shield tunnel segment, for example.
In general, a segment that is one member to be fastened and a segment that is another member to be fastened are fastened with bolts.
However, the joint surface may be forced to open due to an external force of earthquake or ground strain after fastening.
At that time, if it is a normal bolt, there is a possibility that it will be pulled and broken or the fitting will be damaged.
Therefore, as a joint having a function of absorbing such a displacement, for example, there is a method using an elastic washer a as shown in FIG.
This is because, when the fittings b attached to the segments are fastened with ordinary bolts c and nuts d, a thick cylinder is made of an elastic washer by a material having an elastic coefficient much smaller than that of a rigid material, that is, a material that is easily compressed and deformed. It is a structure used as a.
With such a structure, when the segments are opened, the elastic washer a is elastically deformed to absorb the displacement, and there is an effect that excessive stress is not generated in the bolt c and the joint fitting b. .

以下において、図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   In the following, preferred embodiments of the present invention will be described in detail with reference to the drawings.

＜１＞基本的構成。
本発明の基本的な構成を図１に示す。
すなわち本発明の継手は、剛質材製の外筒１と、外筒１の内部に位置する剛質材製の芯材２と、外筒１と芯材２の間に位置する弾性体３によって構成する。
この弾性体３は、特に剛質材より弾性係数の小さい弾性材料によって構成する。
この芯材２、弾性体３、外筒１は相互に十分な強度を持つ接着剤によって一体化する。
なお、図１の実施例では円筒形の外筒１、芯材２を示しているが、角筒、角柱によって構成することもできる。
なお、本明細書において「剛質材」「剛質材製」とは、典型的には鋼材を意味するが、その他に鋼材と同等以上に剛性、強度の高い、公知の材料を示すものである。 <1> Basic configuration.
A basic configuration of the present invention is shown in FIG.
That is, the joint of the present invention includes a rigid material outer cylinder 1, a rigid material core 2 positioned inside the outer cylinder 1, and an elastic body 3 positioned between the outer cylinder 1 and the core material 2. Consists of.
The elastic body 3 is made of an elastic material having an elastic coefficient smaller than that of a rigid material.
The core material 2, the elastic body 3, and the outer cylinder 1 are integrated by an adhesive having sufficient strength.
In addition, although the cylindrical outer cylinder 1 and the core material 2 are shown in the Example of FIG. 1, it can also be comprised with a square cylinder and a prism.
In this specification, “rigid material” and “made of rigid material” typically mean steel material, but also indicate known materials having rigidity and strength equal to or higher than those of steel materials. is there.

＜２＞基本的構成の機能。
図１に示した構成の継手において、その外筒１を一方の被締結部材に、芯材２を他の被締結部材に取付ける。
そして被締結部材に反対方向の外力が作用した場合に、図２に示すように外筒１と芯材２との間に相対変位が生じる。
この相対変位は弾性体３がせん断変形することによって、その変位を吸収することができる。
この変位によって継手全体には過度な応力が作用せず、破壊から逃れることができる。
この相対変位に応じて発生する力の大きさは、弾性体３のせん断弾性係数の大きさによって正確にコントロールすることができる。
また、外力を開放すれば、弾性体３の復元力によって外筒１と芯材２とは原形に戻ることになる。
なお、被締結部材の間の目開きが生じる前に、継手を締め付ける過程ですでに外筒１と芯材２との間では変位が生じている。
したがって地震などにより生じる目開きに対しては、締結時の変位からの増分として機能することになる。 <2> Functions of the basic configuration.
In the joint having the configuration shown in FIG. 1, the outer cylinder 1 is attached to one fastened member, and the core member 2 is attached to the other fastened member.
And when external force of the opposite direction acts on a to-be-fastened member, relative displacement arises between the outer cylinder 1 and the core material 2 as shown in FIG.
This relative displacement can be absorbed by the elastic body 3 undergoing shear deformation.
By this displacement, excessive stress does not act on the entire joint, and it is possible to escape from fracture.
The magnitude of the force generated according to this relative displacement can be accurately controlled by the magnitude of the shear elastic modulus of the elastic body 3.
If the external force is released, the outer cylinder 1 and the core material 2 return to the original shape by the restoring force of the elastic body 3.
In addition, before the opening between fastening members arises, the displacement has already arisen between the outer cylinder 1 and the core material 2 in the process of fastening a joint.
Therefore, for an opening caused by an earthquake or the like, it functions as an increment from the displacement at the time of fastening.

＜３＞実施例の１．（図３、４、５）
前記の基本の構成と同様に、継手は剛質材製の外筒１と、外筒１の内部に位置する剛質材製の芯材２と、外筒１と芯材２の間に位置する弾性体３によって構成する。
そして外筒１の外周にはネジ山を刻設する。
一方、弾性体３を介して外筒１の内部に配置した芯材２の一端には角柱状の芯材頭部２１を形成する。
芯材頭部２１の形状は、例えば芯材２の外径や外筒１の外径よりも最小幅の大きい六角柱であり、通常のボルトのボルト頭部と同様の形状である。
そしてネジの刻設部分と、芯材頭部２１とは反対の方向に位置させる。
したがって、外観、および使用方法は通常のボルトと同じである。
締結時には、図４に示すように、２枚の被締結部材６のボルト穴６１を通して外筒１を挿入し、被締結部材６の反対側に露出した外筒１のネジに、ナット４を締め付ける。
芯材頭部２１と被締結部材６の間、ナット４と他の被締結部材６の間にはワッシャー５を介在させることも一般のボルト締結と同様の構成である。
この２枚の被締結部材６の間に反対方向の外力が作用して目開きＨが生じた場合に、図５に示すように、外筒１側はナット４とともに一方に移動し、芯材２は芯材頭部２１とともに反対方向に移動する。
その結果、外筒１と芯材２の間に介在する弾性体３がせん断変形してその変位を吸収する。
この変位によって継手には過度な応力が作用せず、継手や継手金具の破壊を避けることができる。 <3> Example 1 (Fig. 3, 4, 5)

On the other hand, a prismatic core material head 21 is formed at one end of the core material 2 disposed inside the outer cylinder 1 via the elastic body 3.
The shape of the core material head 21 is, for example, a hexagonal column having a minimum width larger than the outer diameter of the core material 2 and the outer diameter of the outer cylinder 1, and is the same shape as the bolt head of a normal bolt.
And the engraved part of a screw and the core head 21 are positioned in the opposite direction.
Therefore, the appearance and usage are the same as those of ordinary bolts.
At the time of fastening, as shown in FIG. 4, the outer cylinder 1 is inserted through the bolt holes 61 of the two fastened members 6, and the nut 4 is fastened to the screw of the outer cylinder 1 exposed on the opposite side of the fastened member 6. .
The washer 5 is interposed between the core head portion 21 and the fastened member 6 and between the nut 4 and the other fastened member 6 in the same configuration as in general bolt fastening.
When an external force in the opposite direction acts between the two fastened members 6 and a mesh H is generated, the outer cylinder 1 side moves to one side together with the nut 4 as shown in FIG. 2 moves together with the core head 21 in the opposite direction.
As a result, the elastic body 3 interposed between the outer cylinder 1 and the core material 2 shears and absorbs the displacement.
Due to this displacement, excessive stress does not act on the joint, and it is possible to avoid breakage of the joint and the fitting.

＜４＞実施例の２．（図６）
前記の基本の構成と同様に、継手は剛質材製の外筒１と、外筒１の内部に位置する剛質材製の芯材２と、外筒１と芯材２の間に位置する弾性体３によって構成する。

この２枚の被締結部材６の間に反対方向の外力が作用して目開きが生じた場合に、一方の芯材２はその露出端に取付けたナット４とともに一方に移動し、他方の芯材２はその露出端に取付けたナット４とともに反対方向に移動する。
その結果、外筒１と各芯材２の間に介在する弾性体３がせん断変形してその変位を吸収する。
この変位によって継手には過度な応力が作用せず、継手の破壊から逃れることができる。 <4> Example 2 (Fig. 6)

Each nut 4 is attached to the screw of each core material 2 which penetrates this joint to the bolt hole 61 of the to-be-fastened member 6 of 2 sheets, and was exposed to both sides.
When an external force in the opposite direction acts between the two fastened members 6 and a mesh is generated, one core member 2 moves to one side together with the nut 4 attached to the exposed end, and the other core The material 2 moves in the opposite direction with a nut 4 attached to its exposed end.
As a result, the elastic body 3 interposed between the outer cylinder 1 and each core member 2 is sheared to absorb the displacement.
Due to this displacement, excessive stress does not act on the joint, and it is possible to escape from destruction of the joint.

＜５＞実施例の３．（図７）
前記の基本の構成と同様に、継手は剛質材製の外筒１と、外筒１の内部に位置する剛質材製の芯材２と、外筒１と芯材２の間に位置する弾性体３によって構成する。
そしてこの実施例では外筒１は２本の外筒１で構成する。
それに対して両外筒１の内部に位置する芯材２の方は１本の芯材２で構成する。
そして外筒１と芯材２の間には弾性体３を位置させる。
さらに外筒１の外周の少なくとも両端にはネジを刻設する。
この継手を、２枚の被締結部材６のボルト穴６１に貫通し、両側に露出した外筒１のネジに、おのおのナット４を取付ける。
この２枚の被締結部材６の間に反対方向の外力が作用して目開きが生じた場合に、一方の外筒１はネジを介して取付けたナット４とともに一方に移動し、他方の外筒１はネジを介して取付けたナット４とともに反対方向に移動する。
その結果、各外筒１と、共通する芯材２の間に介在する弾性体３がせん断変形してその変位を吸収する。
この変位によって継手には過度な応力が作用せず、継手の破壊から逃れることができる。 <5> Example 3 (Fig. 7)
