上によりライニング材15の取付けが完了する。In this state, a screw nut 2 is screwed into the screw hole 4 of the embedded nut 1 using a hexagonal wrench (not shown), the lining material 15 is attached to the surface of the steel plate 12 via the washer 19, and the bolt 3 is attached. It is passed through the tapered recess 17 of the lining material 15 and rotated forward to be screwed onto the screw-in nut 2. After that, the tapered recess 17 is filled with the resin 20 to cover the head 9 of the bolt 3 and the surface of the resin 20 is made to coincide with the surface of the lining material 15. With the above, the attachment of the lining material 15 is completed.

材15の取付けを片側から短時間に且つ容易に行うことが
できる。At this time, since the screw nut 2 is screwed and fixed to the embedded nut 1 fixed to the steel plate 12, and the lining material 15 is locked by the stopper 14 of the steel plate 12 and positioned, the bolt is fixed. 3 can be easily screwed into the screw nut 2. Moreover, since the screw-in nut 2 is screwed and fixed to the embedded nut 1 as described above, it does not rotate together when the bolt 3 is screwed. Therefore, the lining material 15 can be easily attached from one side in a short time.

によりボルト３及びねじ込ナット２が破損することがあ
る。When solid matter such as sand accumulated in the reservoir of the dam is discharged from the sand discharge channel, the lining material on the channel wall surface of the sand discharge channel 15
Sand or the like collides with the lining material 15, causing wear on the lining material 15. At the same time, a strong impact force acts on the bolt 3 for mounting the lining material 15 and the screw nut 2 screwed onto the bolt 3, and the impact force causes the impact. The bolt 3 and the screw nut 2 may be damaged.
この際、ねじ込ナット２の外周の埋込ナット１に螺合

６より面積がかなり大きくなっているため、ボルト３に
作用する衝撃力により内周の雌ねじ部６が破損したとき
にも、外周の雄ねじ部５は破損にまで至ることがないの
で、埋込ナット１のねじ孔４は保全される。At this time, the male screw portion 5 screwed to the embedded nut 1 on the outer circumference of the screw nut 2 has a considerably larger area than the female screw portion 6 screwed to the bolt 3 on the inner circumference, and therefore acts on the bolt 3. Even when the female screw portion 6 on the inner periphery is damaged by the impact force, the male screw portion 5 on the outer periphery is not damaged, so that the screw hole 4 of the embedded nut 1 is maintained.
従って、新しいボルト３とねじ込ナット２を用いて前
記と同様の手順を行うことにより、簡単な作業で何度で
も繰り返しライニング材15の交換、固定を行うことがで
きる。Therefore, by performing the same procedure as described above using the new bolt 3 and the screw-in nut 2, the lining material 15 can be repeatedly exchanged and fixed by a simple operation.
又、鋼板12にボルト３の貫通孔13を設け、該貫通孔13
の下方に埋込ナット１を固定する構成としているので、
鋼板に直接ねじ孔等を設ける場合に比べて鋼板12の加工
に要する手間が最小限に抑えられる。Further, a through hole 13 for the bolt 3 is provided in the steel plate 12, and the through hole 13
Since the embedded nut 1 is fixed below the
Compared with the case of directly providing a screw hole or the like on the steel plate, the labor required for processing the steel plate 12 can be minimized.
更に、砂等の衝突により、ライニング材15の凹入部17
やボルト３の頭部９にも損傷が発生するが、このことを
考慮し、凹入部17及び頭部９にテーパ部を設け、面取り
をしておけば、凹入部17やボルト３の頭部９におけるバ
リの発生を防止したり、或いは発生するバリを小さく抑
えることができるので、ボルト３やねじ込ナット２等の
交換作業を容易に行うことができる。Further, due to collision with sand or the like, the recessed portion 17 of the lining material 15
Although the head portion 9 of the bolt 3 and the bolt 3 is also damaged, in consideration of this, if the recessed portion 17 and the head portion 9 are tapered and chamfered, the recessed portion 17 and the head portion of the bolt 3 are formed. Since it is possible to prevent the occurrence of burrs in 9 or to suppress the burrs to be small, it is possible to easily perform the replacement work of the bolt 3, the screw nut 2, and the like.
またボルト３の交換作業は種々の方式で行うことがで
きるが、例えば、ライニング材15のテーパ状凹入部17か
ら樹脂20を除去し、ボルト３軸芯部にドリルで下穴を穿
設した後、逆ねじタップを用いて前記下穴に逆ねじ切り
をすることによりボルト３をねじ込ナット２から引抜
き、その後ライニング材15を剥離して、六角レンチによ
りねじ込ナット２を取り出すようにする。The bolt 3 can be replaced by various methods. For example, after removing the resin 20 from the tapered recess 17 of the lining material 15 and drilling a pilot hole in the shaft core of the bolt 3, The bolt 3 is pulled out from the screw-in nut 2 by reverse-threading the prepared hole using a reverse screw tap, and then the lining material 15 is peeled off, and the screw-in nut 2 is taken out with a hexagon wrench.
第２図は本考案の他の実施例であり、埋込ナット１′
を鋼板12の貫通穴13′内部に埋込み固定装着するように
した構成以外は第１図に示すものと同様の構成を有する
ものであり、第１図の場合に発揮される効果を発揮する
のは勿論、第１図の場合に比しねじ込ナット２の位置が
ライニング材15側に寄るので、ボルト３の長さを短くな
し得られ且つねじ込ナット２の取付け取外しが容易とな
る、等の効果も発揮する。FIG. 2 shows another embodiment of the present invention, which is an embedded nut 1 '.
1 has the same structure as that shown in FIG. 1 except that it is embedded and fixedly mounted in the through hole 13 'of the steel plate 12, and exhibits the effect exhibited in the case of FIG. Of course, as compared with the case of FIG. 1, the position of the screw-in nut 2 is closer to the side of the lining material 15, so that the length of the bolt 3 can be shortened and the screw-in nut 2 can be easily attached and detached. Also exerts the effect of.
尚、本考案の板材固定具は、上述の実施例にのみ限定
されるものではなく、本考案の要旨を逸脱しない範囲内
において種々変更を加え得ることは勿論である。It should be noted that the plate fixing device of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention.
［考案の効果］ 以上説明したように、本考案の板材固定具によれば、
下記の如き種々の優れた効果を奏し得る。[Effects of the Invention] As described above, according to the plate member fixture of the present invention,
Various excellent effects as described below can be obtained.
