Definitions
- the present invention relates to a bolt connector for connecting long bolts used mainly in a wooden house.
- a high nut (long nut) etc. are generally known as what connects the long bolt used for a wooden house.
- bolt through holes are formed in the upper and lower floors, and long bolts are inserted through the bolt through holes to connect with high nuts etc., the distance between the upper and lower floors is several meters Because of this, the center of the bolt through hole of the girder often deviates, which causes the axial centers of the bolts to deviate, which makes it difficult to insert the bolt into the high nut itself.
- this nut also has to be screwed to the long bolt, and there is a disadvantage that it takes time and effort to move the nut in the axial direction of the bolt.
- the present invention can easily insert a bolt into a high nut, and can easily maintain a screwing state of the bolt and the nut, and a bolt connection method
- the purpose is to provide.
- the bolted connector according to the present invention is a bolted connector for connecting two bolts, comprising: a high nut having a female thread; and a spring partially inserted into the female thread.
- the female screw portion is formed to have a diameter larger than the outer diameter of the bolt, and the spring is rotated in a state where the bolt or a high nut is rotated and tightened. It is characterized in that it is formed in a shape that contacts a thread.
- the female screw portion is formed to have a diameter larger than the outer diameter of the bolt while a part of the spring is inserted into the female screw portion. Therefore, even if the axial centers of the long bolts on the upper and lower floors are offset, the bolts can be guided by the springs protruding from the female threads, and the misalignment can be eliminated.
- the spring When the spring is tightened, the spring is formed to be in contact with the threads of the female thread and the male thread of the bolt, so the play space between the male thread and the female thread is reduced to prevent loosening You can get the effect.
- the female screw portion is formed to have a diameter larger than the outer diameter of the bolt, so the high nut can be moved in the bolt inserted state without rotating the bolt or the high nut, and the connection position is easily The high nut can be moved up.
- the internal thread portion is formed to have a large diameter, higher joint strength can be obtained than using a nut of a size which is screwed with a bolt as usual.
- the same effects as in the above (1) to (4) can be obtained, and by forming the large diameter portion, the bolt can be guided more easily. it can.
- the same effects as in (1) to (5) can be obtained, and the spring is more closely attached to the threads of the internal thread and the external thread of the bolt. It can be made to contact.
- FIGS. 15 to 18 are explanatory views showing a fourth embodiment of the present invention.

- the high nut 4 is made of metal and formed in a hexagonal outer shape, and the central portion in the axial direction communicates with the one end surface 4a to the other end surface 4b.
- a female screw portion 3 is formed.
- the female screw 3 is formed into a millimeter screw or an inch screw, and specifically, when the male screw 6 of the same type as the male screw 6 formed on the bolt 2, for example, the male screw 6 of the bolt is a millimeter screw
- the female screw portion 3 is also formed with a millimeter screw.
- near both end portions (outside portion) of the female screw portion 3 are formed in the large diameter portion 7 having a diameter larger than that of the inner side. It is desirable that the connection portion between the large diameter portion 7 and the inner small diameter portion 8 be smoothly connected so as to be entirely tapered.
- the inner diameter of the female screw portion 3 is formed to be larger than the outer diameter of the bolt 2 even in the smallest portion (small diameter portion 8), and the high nut 4 is rotated when connecting the bolt 2 It does not need to be moved and can be moved easily. Further, since the female screw portion is formed to have a large diameter, it is possible to obtain about 20% higher bonding strength than using a nut sized to be screwed with a bolt as usual.
- the spring 5 has a substantially diamond shape in cross section, and contacts the threads of the female thread 3 and the threads of the male thread 6 of the bolt in a bolt connection state (a state in which the bolt is tightened). It has a shape.

- the centers of the long bolt 2 (2 ') attached to the lower floor girder 9 and the long bolt 2 (2' ') attached to the upper floor girder 10 are shifted.
- the tip of the bolt 2 is inserted into the inside of the spring 5 and this spring 5 serves as a guide and the tip of the long bolt 2 is After that, by rotating the bolt 2 or the high nut 4 so as to tighten the bolt 2, the bolt 2 is screwed in the inward direction of the high nut 4 along the screw thread of the female screw portion 3 and the spring 5. The misalignment of the bolt 2 is gradually eliminated.
- the bolts 2 on the upper and lower floors can be easily connected even in the case of using the bolt 2 having a large diameter, for example. it can.
- the spring 5 and the male screw 6 enter inside the small diameter part 8 of the female screw 3, and the spring 5 is a thread of the female screw 3 and the male screw 6 as shown in FIG. Contact and screw in close contact with each other.
- the spring 5 contacts the threads of the female screw 3 and the male screw 6 in a close contact state (generally in surface contact) in this manner, the free space (clearance) between the female screw 3 and the male screw 6 is filled with the spring 5.
- the frictional force of the spring 5 can provide a locking effect.
- the high nut 4 alone is used to connect the bolt 2.
- a so-called double nut nut is brought into contact with the high nut 4 to obtain a firmer locking effect. It may be possible to
- the bolt connector 1 of the present invention When the bolt connector 1 of the present invention is used, it is possible to prevent misalignment or the like even if the bolt 2 is simply passed through the upper and lower floors 9 and 10 and connected with the bolt connector 1 so that the bolts 2 can be easily For example, as shown in FIG. 7, a bolt 2 (2 ′) is attached to the lower floor girder 9 and a high nut 4 is inserted (freely inserted) into the bolt 2 (2 ′). The spring 5 is screwed in the vicinity of the tip of the bolt 2 (2 ').
- this spring 5 is bent and the other end is screwed with the tip of the bolt 2 (2 ′ ′). Thereafter, the bolt 2 (2 ′ ′) is attached to the upper floor girder 10 and the high nut 4 is The bolts 2 can be easily connected to each other by moving them to the connection portion of these bolts and tightening them, and when these bolts 2 and 2 are connected, a state as shown in FIG. 8 is obtained.
- a nut 11A having a nut segment may be used or a normal nut 11 may be used as the nut 11 fixing the bolt 2 to the girders 9 and 10 of the upper and lower floors.
- a normal nut 11 When a normal nut 11 is used, the nut 11 having a diameter larger than the outer diameter of the bolt 2 may be used and the spring 5 may be used for tightening.

Description
また、このように接続した長尺のボルトと高ナットの螺合部分が緩まないように、いわゆるダブルナット等を用いてボルトとナットの螺合部にせん断力を付加して緩み止めを施す手法が一般的に知られている。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
(1)請求項1及び請求項7に記載の各発明においては、メネジ部は、メネジ部にスプリングの一部が挿入されているとともに、前記ボルトの外径よりも大径に形成されているので、上下階の長尺ボルトの軸心がずれていても、ボルトがメネジ部から突出したスプリングにガイドされ、芯ずれを解消することができる。
(2)スプリングはボルトを締めつけた状態においては、メネジ部及びボルトのオネジ部のネジ山に接触する形状に形成されているので、オネジ部及びメネジ部の間の遊び空間が減少し、緩み防止効果を得ることができる。
(3)メネジ部は、前記ボルトの外径よりも大径に形成されているので、ボルトや高ナットを回転させることなく、ボルト挿入状態で高ナットを移動させることができ、容易に接続位置まで高ナットを移動させることができる。
(4)また、メネジ部が大径に形成されているので、ボルトと通常通り螺合するサイズのナットを用いるよりも、高い接合強度を得ることができる。
(5)請求項2に記載された発明においても前記(1)~(4)と同様な効果が得られるとともに、大径部を形成していることにより、より容易にボルトをガイドすることができる。
(6)請求項3及び請求項4に記載の各発明においても前記(1)~(5)と同様な効果が得られるとともに、スプリングをよりメネジ部及びボルトのオネジ部のネジ山に密着するように接触させることができる。
(7)請求項6に記載された発明においても前記(1)~(6)と同様な効果が得られるとともに、スプリング等を容易に挿入することができる。

また、メネジ部3の両端部付近(外側部位)は内側よりも大径となる大径部7に形成されている。この大径部7と内側の小径部8との接続部位は、全体的にテーパー状になるように滑らかに接続されていることが望ましい。
ところで、このスプリング5は、各種材料を用いることができるとともに、硬度等も自在に変更することができるので、ボルト2や高ナット4に焼入れ処理等をしなくても、スプリング5に焼入れ処理等をすることで、接合強度を向上させることができる。
次に、図9乃至図18に示す本発明を実施するための異なる形態につき説明する。なお、これらの本発明を実施するための異なる形態の説明に当って、前記本発明を実施するための第1の形態と同一構成部分には同一符号を付して重複する説明を省略する。
