この発明は、二重床などに用いるボルト脚の固定具と固
定方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a fixture and a method for fixing bolt legs used in double floors and the like.
従来は、ボルト脚の頭が入る孔が設けられ、その個所は
挿入された頭が回転できるように、部分的に高く形成さ
れていた。Conventionally, a hole was provided for the head of the bolt leg to be inserted, and the hole was formed partially high so that the inserted head could rotate.
しかし、ボルト脚は頭の際で抑えられるだけであるので
、位置は固定出来ても、ボルト脚が斜めに傾いたり、又
、底がないため、ボルト脚の先端が下のモルタル面に食
い込んでしまうような不都合があるので、ボルト脚を固
定することはできなかった。However, the bolt leg is only held in place near the head, so even if the position is fixed, the bolt leg may tilt diagonally, or because there is no bottom, the tip of the bolt leg may dig into the mortar surface below. It was not possible to fix the bolt legs because it would be inconvenient to store them away.
この問題を解決するために、この発明では、鋼板を屈折
させてコの字状に連なった上下二枚の挟持板を形成する
。二枚の挟持板の間はボルト脚の頭の高さと同じ間隔と
する。In order to solve this problem, in the present invention, a steel plate is bent to form two upper and lower holding plates connected in a U-shape. The distance between the two clamping plates shall be the same as the height of the head of the bolt leg.
上面の挟持板には、ボルト脚の軸が挿入出来る巾のＵ字
型の切込みを設け、底面の挟持板には、ボルト脚の頭が
入る凹みを形成してボルト脚の固定具とする。The upper clamping plate is provided with a U-shaped notch wide enough to allow the shaft of the bolt leg to be inserted, and the bottom clamping plate is formed with a recess into which the head of the bolt leg can be inserted to serve as a fixing device for the bolt leg.
又、このような固定具にボルト脚を挟持せしめた状態で
、固定具を床面に固定することにより、ボルト脚を、間
接的にスラブに固定するものである。Further, by fixing the bolt leg to the floor surface while the bolt leg is held between the fixtures, the bolt leg is indirectly fixed to the slab.
このように構成すると、ボルト脚は切込みと凹みによっ
て固定具に固定される。この固定具を、スラブにアンカ
ーボルト・糊などで固定すれば、間接的にボルト脚はス
ラブに固定される。With this configuration, the bolt leg is fixed to the fixture by the notch and recess. If this fixture is fixed to the slab with anchor bolts or glue, the bolt leg will be indirectly fixed to the slab.
第１図（ａ）に示すのはボルト脚１である。頭部１）、
軸部１２、ネジ部１３から構成され、二重床の床板に取
付られて高さ調節可能な脚として用いられる。A bolt leg 1 is shown in FIG. 1(a). Head 1),
It is composed of a shaft part 12 and a screw part 13, and is used as a height-adjustable leg that is attached to the floorboard of a double floor.
頭部の根本には平坦部１４を設ける。A flat portion 14 is provided at the base of the head.
第１図（ｂｌに示すのは、同じくボルト脚１であるが、
軸部１２が太いので、溝１５を設けて頭部１）を形成す
るとともに、軸部に細い個所を形成しである。Figure 1 (bl shows the same bolt leg 1,
Since the shaft portion 12 is thick, a groove 15 is provided to form the head portion 1), and a thin portion is formed in the shaft portion.
第２図はボルト脚の固定具２である。厚さ２．３寵の亜
鉛メツキ鋼板をコの字状に屈曲し、底板３と抑え板４が
ボルト脚の頭部１）の高さと略同様の距離を保って平行

のバネ性能を保有している。Figure 2 shows a bolt leg fixture 2. A galvanized steel plate with a thickness of 2.3 mm is bent into a U-shape, and a bottom plate 3 and a restraining plate 4 are formed parallel to each other with a distance substantially the same as the height of the head 1) of the bolt leg. Since it is bent in a U-shape, it has some spring performance.
底板３の中央には、周囲を盛り上げた凹み３１を形成す
る。凹みの大きさ・形状はボルト脚の頭部の大きさ・形
状に合致させる。底板の隅には貫通孔３２を設ける。A recess 31 with a raised periphery is formed in the center of the bottom plate 3. The size and shape of the recess should match the size and shape of the head of the bolt leg. Through holes 32 are provided at the corners of the bottom plate.
抑え板４には端部から中央に向けＵ字型の切込み４１を

脚が差込み易いように、差込み口４２を少し上方に反ら
すなどしてもよい。A U-shaped notch 41 is formed in the restraining plate 4 from the end toward the center. The width of the cut is made to approximately match the thickness of the shaft portion 12 of the bolt leg. Further, the depth of the cut is determined such that the deep end of the cut is located just above the recess in the bottom plate. The insertion port 42 may be slightly curved upward to make it easier to insert the bolt leg.
第３図に示すように、固定具２の差込み口側から、ボル

差込む。頭部１）は底板３と抑え板４の間に挟持され、
特に、頭部の根本の平坦部１４が抑え板４に抑えられ、
頭部の先端は凹みの中に安定し、軸部１２は切込みによ
り横方向の動きが規制されるので、ボルト脚１は固定具
２に確りと固定される。As shown in FIG. 3, firmly insert the bolt leg 1 from the insertion opening side of the fixture 2 until the tip of the head 1) enters the recess 31. The head 1) is held between the bottom plate 3 and the holding plate 4,
In particular, the flat part 14 at the base of the head is held down by the holding plate 4,
Since the tip of the head is stable in the recess and the lateral movement of the shaft portion 12 is restricted by the notch, the bolt leg 1 is securely fixed to the fixture 2.
このような状況で、固定具２の底板３の貫通孔３２にコ
ンクリートネイル３３を通してスラブ５に釘付けする。In this situation, the concrete nail 33 is passed through the through hole 32 of the bottom plate 3 of the fixture 2 and nailed to the slab 5.
ボルト脚は固定具に挟持されているので、ボルト脚は間

４図に示すように、底板３の底面に接着剤６を塗布して
、スラブ５に接着して固定してもよい。Since the bolt leg is held between the fixtures, the bolt leg is indirectly fixed to the slab.The fixture 2 of the present invention, as shown in FIG. Then, it may be fixed by adhering to the slab 5.
尚、スラブに不陸がある場合には、第５図に示すように
、底板３の片側に調節板３４を挟むことにより、傾きを
調整することが出来る。If the slab is uneven, the inclination can be adjusted by inserting an adjustment plate 34 on one side of the bottom plate 3, as shown in FIG.
固定具２の形状は、実施例に限定されることはなく、例

することも可能である。The shape of the fixture 2 is not limited to the embodiment, and for example, as shown in FIG. 6, the bottom plate 3 may be short and have no through holes, or as shown in FIG. A part of the bottom plate may be used as the restraining plate 4 and stretched straight without being bent, and a through hole 32 may be provided at the extended portion so that concrete nails can be driven at both ends of the bottom plate. Furthermore, instead of forming a recess, a hole may be made in the bottom plate and the tip of the head may be inserted into the hole.
