Description

【考案の詳細な説明】[Detailed description of the invention]

【考案の属する技術分野】[Technical field to which the invention belongs]

本考案は建物におけるボルトの固着具に関するものであり、特に建物における柱 、土台等の木製部材を貫通させたボルトを固定するための固着具に係るものであ る。 The present invention relates to a fixing device for a bolt in a building, and more particularly to a fixing device for fixing a bolt penetrating a wooden member such as a pillar or a base in a building.

【0002】[0002]

【従来の技術】[Prior art]

このようなボルトを固定するための固着具としては、一般にナットが使用されて いる。即ち、柱、土台等の木製部材を貫通させたボルトの突出端にナットを螺合 させることにより該ボルトを固定するようにしている。 As a fixing tool for fixing such a bolt, a nut is generally used. That is, the bolt is fixed by screwing a nut to a protruding end of the bolt penetrating a wooden member such as a pillar or a base.

【考案が解決しようとする課題】[Problems to be solved by the invention]

しかるに、上記の如くボルトの突出端に単にナットを螺合させたときには、ボル トが貫通している木製部材が痩せた場合にはナットと木製部材との間に隙間が生 じ、ボルトが緩むことになる。しかして、建物の完成時にはボルトの突出端は壁 材、床材、天井材等の内側に隠れてしまうため、ボルトが緩んでもナットを締め 直すことは容易なことではない。また、ボルトの突出端に螺合させたナットは地 震の際の振動によっても緩むおそれがある。 このような状況に鑑み、本考案はボルトが貫通している木製部材が痩せた場合或 いは建物が地震による振動を受けた場合にも、該ボルトが緩まないようにした建 物におけるボルトの固着具を提供しようとしてなされたものである。 However, when the nut is simply screwed into the protruding end of the bolt as described above, if the wooden member through which the bolt passes becomes thin, a gap is created between the nut and the wooden member, and the bolt is loosened. Will be. However, when the building is completed, the protruding ends of the bolts are hidden inside the wall, floor, ceiling, etc., so it is not easy to retighten the nuts even if the bolts are loosened. Also, nuts screwed into the protruding ends of bolts may be loosened by vibration during an earthquake. In view of such circumstances, the present invention provides a bolt for a building in which the bolt does not loosen even if the wooden member through which the bolt passes is thin or the building is subjected to vibration due to an earthquake. It was intended to provide a fastener.

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を解決するために、本考案は、木製部材を貫通させたボルトの突出端に 螺合したナットの緩みをコイルばねにより防止するようにした建物におけるボル トの固着具を提供するものである。即ち、本考案による建物におけるボルトの固 着具は、木製部材を貫通させたボルトの突出端における内側には第一ナットを螺 合し、ボルトの突出端における第一ナットの外側にはコイルばねを外設し、該コ イルばねの内側端を第一ナットに固定し、ボルトの突出端におけるコイルばねの 外側には第二ナットを螺合し、該コイルばねの外側端を第二ナットに固定し、ボ ルトの突出端における第二ナットの外側には第三ナットを螺合し、第一ナットを 木製部材に対して締め付け、第二ナットをコイルばねの力に抗して内側に締め、 第三ナットを第二ナットに密着させることにより、コイルばねが常時第一ナット を締め付ける方向に回動させる傾向を有するようにしたことを特徴とするもので ある。 In order to solve the above problems, the present invention provides a bolt fixing device for a building in which a nut, which is screwed to a projecting end of a bolt penetrating a wooden member, is prevented from being loosened by a coil spring. is there. That is, the bolt fixing device in the building according to the present invention is such that the first nut is screwed inside the protruding end of the bolt penetrating the wooden member, and the coil spring is mounted outside the first nut at the protruding end of the bolt. The inner end of the coil spring is fixed to the first nut, a second nut is screwed on the outside of the coil spring at the protruding end of the bolt, and the outer end of the coil spring is connected to the second nut. Fix it, screw a third nut on the outside of the second nut at the protruding end of the bolt, tighten the first nut against the wooden member, and tighten the second nut inward against the force of the coil spring. The third nut is brought into close contact with the second nut so that the coil spring has a tendency to always rotate in the direction in which the first nut is tightened.

【0005】 実用新案登録請求の範囲を含む本明細書において「外側」とは木製部材を貫通 するボルトの突出端において該木製部材から離れた側をいい、「内側」とは木製 部材を貫通するボルトの突出端において該木製部材に近い側をいうものとする。 また、実用新案登録請求の範囲を含む本明細書における「コイルばね」には鋼線 をコイル状に巻いてなるものの他、鋼帯をコイル状に巻いてなるものも含まれる ものとする。[0005] In the present specification including the claims of the utility model registration, "outside" means a side of the protruding end of the bolt that penetrates the wooden member and away from the wooden member, and "inside" means that penetrates the wooden member. The side near the wooden member at the projecting end of the bolt shall be referred to. In addition, the term “coil spring” in the present specification, including the claims of utility model registration, includes not only a steel wire wound in a coil shape but also a steel wire wound in a coil shape.

【作用】[Action]

ボルトを貫通させた木製部材が痩せた場合或いは建物が地震による振動を受けた 場合に、木製部材を貫通させたボルトの突出端における内側の第一ナットが緩も うとすると、第一ナットはコイルばねにより締め付け方向に回動されるため、 第一ナットは木製部材に対し常時締め付けられた状態に維持される。因みに、コ イルばねの両端は第一ナットと第二ナットとに固定されているのであるが、第二 ナットの外側には第三ナットが密着しているため、第二ナットが外側に緩むこと はない。 If the wooden member through which the bolt is penetrated becomes thin or the building is subjected to earthquake vibration, if the first nut inside the protruding end of the bolt through which the wooden member penetrates loosens, the first nut will become a coil. Since the first nut is rotated in the tightening direction by the spring, the first nut is always maintained in a tightened state with respect to the wooden member. Incidentally, both ends of the coil spring are fixed to the first nut and the second nut.However, the second nut is loosened outward because the third nut is in close contact with the outside of the second nut. There is no.

【考案の実施の形態】[Embodiment of the invention]

次に、本考案の実施の形態を添付図面に従って説明する。 符号1に示すものは建物における柱、土台等の木製部材である。木製部材1を貫 通させたボルト3の突出端3aにおける内側には一例として適宜の座金5等を介 して第一ナット7を螺合する。ボルト3の突出端3aにおける第一ナット7の外 側にはコイルばね9を外設し、該コイルばね9の内側端9aを第一ナット7に固 定する。ボルト3の突出端3aにおけるコイルばね9の外側には第二ナット11 を螺合し、該コイルばね9の外側端9bを第二ナット11に固定する。ボルト3 の突出端3aにおける第二ナット11の外側には第三ナット13を螺合する。第 一ナット7を木製部材1に対して締め付け、第二ナット11をコイルばね9の力 に抗して内側に締め、第三ナット13を第二ナット11に密着させることにより 、コイルばね9が常時第一ナット7を締め付ける方向に回動させる傾向を有する ようになす。 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a wooden member such as a pillar or a base in a building. A first nut 7 is screwed into the protruding end 3a of the bolt 3 through which the wooden member 1 passes through an appropriate washer 5 or the like as an example. A coil spring 9 is provided outside the first nut 7 at the protruding end 3 a of the bolt 3, and the inner end 9 a of the coil spring 9 is fixed to the first nut 7. A second nut 11 is screwed onto the outside of the coil spring 9 at the projecting end 3 a of the bolt 3, and the outer end 9 b of the coil spring 9 is fixed to the second nut 11. A third nut 13 is screwed onto the outside of the second nut 11 at the protruding end 3a of the bolt 3. By tightening the first nut 7 against the wooden member 1, tightening the second nut 11 inward against the force of the coil spring 9, and bringing the third nut 13 into close contact with the second nut 11, the coil spring 9 is It has a tendency to always rotate the first nut 7 in the tightening direction.

【0008】 図1は本考案による固着具を壁材14の内側に隠れてしまう柱等の垂直部材に おけるボルト3に用いた事例を示す。FIG. 1 shows an example in which the fixing device according to the present invention is used as a bolt 3 in a vertical member such as a column that is hidden inside a wall member 14.

【考案の効果】[Effect of the invention]

以上説明したように、本考案によれば、ボルトを貫通させた木製部材が痩せた場 合或いは建物が地震による振動を受けた場合に、木製部材を貫通させたボルトの 突出端における内側の第一ナットが緩もうとすると、第一ナットはコイルばねに より締め付け方向に回動されるため、第一ナットは木製部材に対し常時締め付け られた状態に維持される。従って、木製部材に貫通させたボルトは常に緩みのな い状態に維持される。この効果は、特に建物の完成時に壁材、床材、天井材等の 内側に隠れてしまうために締め直すことが困難なボルトの場合に顕著にあらわれ る。 As described above, according to the present invention, when the wooden member through which the bolt is penetrated becomes thinner or when the building is subjected to vibration due to an earthquake, the inner side of the protruding end of the bolt through which the wooden member penetrates is formed. When the one nut tries to be loosened, the first nut is rotated in the tightening direction by the coil spring, so that the first nut is maintained in a state of being constantly tightened against the wooden member. Therefore, the bolt penetrated through the wooden member is always kept in a loose state. This effect is particularly noticeable for bolts that are difficult to retighten because they are hidden inside walls, floors, ceilings, etc. when the building is completed.
