【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、二重床の高さ調節用ボルトおよびそれを用
いた高さ調節用セットに関する。Description: TECHNICAL FIELD The present invention relates to a double floor height adjusting bolt and a height adjusting set using the same.
〔従来技術〕 二重床を形成する手段としては、いろいろの方式が提
案されているが、その１つとして第３図に示すような二

そして、この二重床の形成の手順はいろいろ採用でき、
特に限定するものではないが、一般的には床面固定脚は
複数個で長尺の根太を支える関係上、位置を微調整する
必要があるので、脚だけを先に基礎床上に固定してしま
うと具合の悪いことも多い。そこで、まず固定脚を根太
側に取付けた状態で根太をもちあげて移動させ位置を決

い。さらに高さ調節用ボルトを回転させて高さを調節し
ているときにもボルトが根太支持板から抜け落ちてしま
うこともある。したがって、従来は抜けを防止するため
に第４図ＡまたはＢに示すような高さ調節用ボルト１が
使用されている。[Prior Art] Various methods have been proposed as means for forming a double bed, one of which is a double bed structure as shown in FIG. That is, the floor fixing legs 4 are fixed on the foundation floor 8, the height adjusting bolts 1 are screwed into the floor fixing legs 4, the nuts 3 are tightened at a desired height, and the joists 5 are supported by the joist support plate 2, and the joists 5 The floor plate 6 is passed over, a floor surface is formed, and a finishing plate is additionally provided thereon to form a double floor.
And the procedure of forming this double floor can be adopted in various ways,
Although it is not particularly limited, in general, since there are a plurality of floor fixing legs to support a long joist, it is necessary to fine-tune the position, so fix only the legs first on the foundation floor first. There are many things that are sick. Therefore, it is often practiced to first raise the joist and move it to fix the position with the fixed leg attached to the joist side. At this time, if the height adjusting bolt comes off from the joist support plate 2, it is not good. Further, when the height adjusting bolt is rotated to adjust the height, the bolt may fall off from the joist support plate. Therefore, conventionally, a height adjusting bolt 1 as shown in FIG. 4A or 4B is used in order to prevent detachment.
第４図Ａは高さ調節用ボルトの上から下まで根太支持
板２のための受板部14の個所を除いて全体にネジ12が切
られており、この場合は、根太支持板２のボルト嵌合用
孔にはネジ山が設けられておらず、ボルトに嵌合したあ
と抜けを防止するために、ボルト頂部にナットを螺合し
ていた。したがってナットがよけいに必要であり、コス
ト高であるとともに高さ調節のためボルトを回転させた
時に、ナットがゆるんで脱落したり、逆に支持板を締め
つけすぎて自由な回転ができなくなるなどの問題があっ
た。FIG. 4A shows that the screws 12 are cut from the top to the bottom of the bolts for height adjustment except for the receiving plate portion 14 for the joist support plate 2. The screw hole was not provided in the bolt fitting hole, and a nut was screwed on the top of the bolt in order to prevent the bolt from coming off after fitting. Therefore, a nut is required for extra protection, and it is expensive, and when the bolt is rotated for height adjustment, the nut loosens and falls off, or conversely, the support plate is too tight to allow free rotation. There was a problem.
そこで、第４図Ｂのように根太支持板２の上部に相当
する高さ調節用ボルトの外周には全くネジが切れておら
ず、円柱状にした構造のものが提案されている。この場
合は根太支持板２が抜け落ちないよう円柱部に切欠き16
を設け、この切欠きにピンをはめこんだりしている。し
かしながら、このような切欠き16とピンの組合せでは、
往々にしてピンがはずれる場合が生じ、固定が不完全に
なりやすい。また別部材のためコスト高となる。Therefore, as shown in FIG. 4B, there is proposed a structure in which the height adjusting bolt corresponding to the upper part of the joist support plate 2 has no column thread at all and has a columnar structure. In this case, a notch is formed in the column to prevent the joist support plate 2 from falling off.
And a pin is inserted into this notch. However, in such a combination of the notch 16 and the pin,
Frequently, the pins may come off, and the fixing is likely to be incomplete. In addition, the cost is increased due to a separate member.
そこで、本発明の目的は、根太支持板が常に回転自在
に保持されるようにすると同時に、根太支持板が高さ調
節用ボルトから絶対に抜け落ちることがないようにする
点にある。Therefore, an object of the present invention is to ensure that the joist support plate is always rotatably held and that the joist support plate never falls off from the height adjusting bolt.
本発明は、高さ調節用ボルトの上端部には僅かの数の
ネジ山部を設け、該ネジ山部の下部はネジ山のない平坦
部を設け、平坦部の下部には受板部を設け、受け板部の
下部にはすべてにあるいは部分的にネジ山部が設けられ

る。According to the present invention, a small number of thread portions are provided at the upper end of the height adjusting bolt, a flat portion having no thread is provided at a lower portion of the thread portion, and a receiving plate portion is provided at a lower portion of the flat portion. The present invention relates to a double-floor height adjusting bolt, characterized in that a thread portion is provided entirely or partially at a lower portion of a receiving plate portion.
本発明の他の一つは、根太を支持するに充分な強度を
もつ根太支持板および該根太支持板の厚みと同じかそれ

セットに関する。Another aspect of the present invention is a double-floor height adjustment according to claim 1, comprising a joist support plate having sufficient strength to support the joist and the flat portion having a thickness equal to or larger than the thickness of the joist support plate. The present invention relates to a double-floor height adjusting set characterized by comprising bolts for use in flooring.
本発明を図面を参照して説明する。 The present invention will be described with reference to the drawings.
本発明の二重床高さ調節用ボルトは第１図Ｂでその縦
断面図を、第２図Ｂでその平面図を示す。FIG. 1B shows a longitudinal sectional view of the double floor height adjusting bolt of the present invention, and FIG. 2B shows a plan view thereof.

部12が形成されている。高さとの関係で、例えば受板部
のすぐ下の部分は必ずしもネジを切る必要がない場合も
ある。この場合には部分的にネジを切ればよい。The double floor height adjusting bolt 1 of the present invention has a thread portion 11 having a small number, for example, two or three threads at its upper end.
A flat portion 15 having no thread is provided below the thread portion 11.
Is provided below the flat portion 15, and a receiving plate portion 14 is provided.
The threaded portion 12 is formed entirely or partially at the lower portion. Depending on the height, for example, the portion immediately below the receiving plate may not necessarily need to be threaded. In this case, the screws may be partially cut.
本発明の二重床高さ調節用ボルト１は第３図に示すよ

いか、大きいように構成されている。したがって、根太
支持板２はこの位置においては回転は全く自由であり、
調節用ボルト頂部のネジやネジを利用してボルトを
回転させても、ボルト１と根太支持板２がネジでしまっ
てしまい動かなくなるというおそれはない。As shown in FIG. 3, the double floor height adjusting bolt 1 of the present invention is provided with a thread hole 21 capable of engaging the joist support plate 2 with the screw thread 11. Rotating through
The flat portion 15 having no thread is fitted and supported by the receiving plate portion 14. The height b of the flat portion is configured to be equal to or greater than the thickness a of the joist support plate. Therefore, the joist support plate 2 is completely free to rotate at this position,
Even if the bolt is rotated by using a screw or a screw at the top of the adjusting bolt, there is no possibility that the bolt 1 and the joist support plate 2 are screwed and do not move.
本発明の調節用ボルト１は床面にボルト９で固定され
ている床面固定脚４に第３図に示すようにネジ嵌合によ
り結合させ、高さを調節した後ナット部材３で固定す
る。As shown in FIG. 3, the adjusting bolt 1 of the present invention is fixed to the floor fixing legs 4 fixed to the floor surface with bolts 9 by screw fitting as shown in FIG. .
一方、根太支持板２には根太５を嵌合させ、この根太
５と隣りの根太との間に床板６を渡して二重床を形成
し、その上に仕上床を載置する。On the other hand, a joist 5 is fitted to the joist support plate 2, a floor plate 6 is passed between the joist 5 and an adjacent joist to form a double floor, and a finishing floor is placed thereon.
調節用ボルト１の受板部14は床を支持しうるに足る大
きさと厚みがあればその形状、大きさは何の制約もな
い。The shape and size of the receiving plate portion 14 of the adjusting bolt 1 are not limited as long as the receiving plate portion 14 has a size and thickness sufficient to support the floor.
根太支持板２は、１枚の板状体を例示したが、ネジ孔

が、これに限るものではない。Although the joist support plate 2 is exemplified by a single plate, a reinforcing member is preferably laminated around the screw hole. Further, the joist supporting plate 2 is exemplified by a rectangular one, but may be square. In short, as long as the joist 5 can be fitted and supported by the joist 5, its shape, thickness and material are arbitrary. In this example, the nail 22 is used to engage with the joist 5. The material is usually iron, but is not limited to this.
