【考案の詳細な説明】
本考案は、例えばマンホール、バルブピット等の路面蓋
を設置する場合、又は大型機械を設置する場合に使用さ
れる高さ調整具に関し、殊に高低の荒調整及び微調整の
できる高さ調整具に関する。[Detailed description of the invention] The present invention relates to a height adjustment tool used when installing road surface covers such as manholes and valve pits, or when installing large machinery, and is particularly suitable for rough height adjustment and fine adjustment. It relates to an adjustable height adjuster.
従来、マンホール、バルブピット等の路面蓋を設置する
場合は、蓋体と路面との高さの調整に当って、第８図に
示されるように、枠体１１′と側塊１２との間に石片、
木片等１３を喰ませて調整していた。Conventionally, when installing road surface covers such as manholes and valve pits, when adjusting the height between the cover body and the road surface, as shown in FIG. a piece of stone,
I was adjusting it by eating 13 pieces of wood.
又、大型機械を設置する場合も、その高さを調整するに
当って、機械と土台との間に石片、木片等を喰ませて調
整していた。Also, when installing a large machine, the height was adjusted by inserting pieces of stone, wood, etc. between the machine and the base.
しかしながら、この高さ調整方法は、所要の高さに相当
する石片、木片等を調達することが困難であり、その調
整に手間がかかり、かつ位置決めがしにくく、又、支持

に、コンクリート１２′が完全に充填できず、このため
路面蓋にあっては繰り返し通過する車両の荷重により、
コンクリート１２′が破損することが多いという欠点を
有した。However, with this height adjustment method, it is difficult to procure pieces of stone, wood, etc. that correspond to the required height, and the adjustment is time-consuming, difficult to position, and the support is unstable. In this case, the concrete 12' cannot be completely filled because a vibrator etc. cannot be used, and as a result, due to the load of vehicles repeatedly passing over the road surface cover,
This had the disadvantage that the concrete 12' was often damaged.
その上、木片を用いると、吸湿状態と乾燥状態では体積
が変化するため、コンクリート１２′に亀裂等が発生す
るという欠点を有した。Moreover, when wood chips are used, the volume changes between the moisture-absorbed state and the dry state, which has the disadvantage that cracks and the like occur in the concrete 12'.
本考案の目的は、高さの調整が簡単かつ容易であるとと
もに、路面蓋等が堅固に設置できるという高さ調整具を
提供することであり、その構成は、荒調整用の切断溝を
形成した支持部の一端に、ネジ溝を形成した微調整部を
固着し、且つ、このネジ溝に被支持部材を支えるための
螺挿部材を螺動可能に螺挿したことを特徴とする高さ調
整具である。The purpose of the present invention is to provide a height adjustment tool that allows for simple and easy height adjustment and allows for secure installation of road surface covers, etc., and its configuration is such that cutting grooves are formed for rough adjustment. A fine adjustment part having a threaded groove is fixed to one end of the support part, and a threaded member for supporting a supported member is threadably inserted into the threaded groove. It is an adjustment tool.
以下、本考案の実施例を図面に基づいて説明する。Hereinafter, embodiments of the present invention will be described based on the drawings.
第１〜４図に示すように、高さ調整具１は微調整部２と
、支持部３とから構成され、微調整部２は雄のネジ溝が
形成され、円柱状の支持部３と長手方向に一体戒形され
ている。As shown in FIGS. 1 to 4, the height adjuster 1 is composed of a fine adjustment part 2 and a support part 3. The fine adjustment part 2 is formed with a male screw groove, and has a cylindrical support part 3. It is integrally shaped in the longitudinal direction.
この高さ調整具１には、必要に応じて微調整部２に高さ
を調整するための微調整用ナツト４と締め付は用ナツト
４′とが螺動可能に螺挿されている。A fine adjustment nut 4 and a tightening nut 4' are screwably screwed into the height adjustment tool 1 to adjust the height of the fine adjustment portion 2 as necessary.
なお微調整用ナツト４及び締め付は用ナツト４′は六角
ナツトに限定されるものではなく、例ええば第５図に示
されるごとく、雌ネジ６の形成されたナツト１４゜１４
′を用いることもできる。Note that the fine adjustment nut 4 and the tightening nut 4' are not limited to hexagonal nuts; for example, as shown in FIG.
′ can also be used.
さらに、本実施例では微調整部２を雄ネジで形成したが
、第６図に示されるように微調整部２を雌ネジとし、そ
の微調整部２に、雄ネジを設けた支持片１５を螺挿して
高さ調整をすることもできる。Furthermore, in this embodiment, the fine adjustment part 2 is formed with a male thread, but as shown in FIG. You can also adjust the height by screwing in.
なお、微調整用ナツト１４．１４および、雄ネジを設け
た支持片１５は、この考案における螺挿部材に相当する
。The fine adjustment nuts 14, 14 and the male threaded support piece 15 correspond to the threaded member in this invention.
一方、支持部３は、その側周面に、切断しゃすいように
軸方向と直角方向に断面略Ｕ字状の切断溝５が穿設され
ている。On the other hand, the supporting portion 3 has a cutting groove 5 having a substantially U-shaped cross section in a direction perpendicular to the axial direction to facilitate cutting.
この切断溝５は横断面が楔状でもよく、切削やプレス成
形により穿たれる。The cutting groove 5 may have a wedge-shaped cross section and is formed by cutting or press forming.
次に本考案に係る高さ調整具を枠と蓋とからなるマンホ
ール鉄蓋の設置に使用する場合について第７図に基づい
て説明する。Next, the case where the height adjuster according to the present invention is used for installing a manhole iron cover consisting of a frame and a lid will be explained based on FIG. 7.
まず、微調整部２によって、枠１１の下端部に延設され
た表面に、透孔８を有するフランジ７（この考案におけ
る被支持部材に相当する）を支持する場合は、微調整部
２に予め微調整ナツト１４を螺挿腰その上にフランジ７
を嵌接した後、締め付は用ナツト１４′を螺挿してフラ
ンジ７を締めつける。First, when the fine adjustment section 2 supports the flange 7 (corresponding to the supported member in this invention) having the through hole 8 on the surface extending to the lower end of the frame 11, the fine adjustment section 2 Screw in the fine adjustment nut 14 in advance and place it on the flange 7.
After fitting, tighten the flange 7 by screwing in the nut 14'.
そして、高さ調整具１の支持部３を切断溝５の個所で切
断することにより、蓋９を路面１０と面一にさせるべく
、枠１１と側塊１２との高さの荒調整をする。Then, by cutting the support part 3 of the height adjuster 1 at the cutting groove 5, the heights of the frame 11 and the side blocks 12 are roughly adjusted so that the lid 9 is flush with the road surface 10. .
その後に、微調整部２に螺挿された微調整用ナツト１４
と締め付は用ナツト１４′を螺動させてこれらのナツト
１４，１４′により挟まれたフランジ７の高さを微調整
する。After that, the fine adjustment nut 14 screwed into the fine adjustment part 2
For tightening, screw the nuts 14' to finely adjust the height of the flange 7 sandwiched between these nuts 14, 14'.
高さ調整の終了後、側塊１２と路面１０との間にコンク
リート１２′を充填するものである。After the height adjustment is completed, concrete 12' is filled between the side mass 12 and the road surface 10.
本考案は上記のように構成されているため、支持部を切

大型機械の設置における高さの調整が設置現場で正確か
つ迅速にできるため、作業時間の短縮化を図ることがで
き、ひいては作業能率の向上を図ることができるもので
ある。Since the present invention is constructed as described above, the height can be roughly adjusted by simply and easily cutting the support part at the cutting groove, and the screw insertion member in the fine adjustment part can be easily adjusted. Because the height can be finely adjusted by screwing,
For example, installation of road surface covers such as manholes and valve pits, and height adjustments when installing large machinery can be done accurately and quickly at the installation site, reducing work time and improving work efficiency. It is something that can be done.
