【考案の詳細な説明】
この考案は、内部に仕切弁や止水弁などを収納するため
地中に埋設状に設置する地中弁用弁筺に関するものであ
る。[Detailed description of the invention] This invention relates to a valve case for an underground valve that is installed underground to house a gate valve, a water stop valve, etc. inside.
地中の仕切弁や止水弁などを収納するため地中に埋設す
る弁筺は各種知られているし、外筒体に内筒体を螺合さ
せて内筒体に設けた蓋材の高さを適宜に変更できるよう
にした弁筺も、例えは実公昭57−1693に公報によ
ってすでに知られている。Various types of valve cabinets are known that are buried underground to store underground gate valves, water stop valves, etc. A valve casing whose height can be changed as appropriate is already known, for example, from the publication of Utility Model Publication No. 57-1693.
しかし、従来の内筒体と外筒体とからなる弁筺は、内筒
体の外周全面に雄ネジ部を形成しである。However, the conventional valve housing composed of an inner cylinder body and an outer cylinder body has a male threaded portion formed on the entire outer periphery of the inner cylinder body.
したがって外筒体と内筒体との間隙に土砂などが流入し
ないよいに閉塞するには内筒体の外周面に形成した雄ネ
ジ部を避けなければならない。Therefore, in order to block the gap between the outer cylindrical body and the inner cylindrical body to prevent dirt and the like from flowing in, it is necessary to avoid the male threaded portion formed on the outer peripheral surface of the inner cylindrical body.
また、路面補修によって内筒体の高さを変える場合には
内筒体の上方周囲及び外筒体の上方周囲を堀り起こして
土砂を取り除き、その後外筒体の上面に取付けたリング
材を外してから内筒体を回転させなければならない。In addition, when changing the height of the inner cylinder due to road surface repair, excavate the upper circumference of the inner cylinder and the upper circumference of the outer cylinder to remove earth and sand, and then remove the ring material attached to the top of the outer cylinder. You have to remove it and then rotate the inner cylinder.
したがって、内筒体の高さ調節をする場合の作業が極め

本考案は上記に鑑み提案されたもので、その要旨とする
ところは内筒体の外周面に形成する雄ネジ部を下方一部
にすることによって、地中埋設後であっても内筒体の高
さを大きく、また簡単に変えることができるようにした
ものである。Therefore, adjusting the height of the inner cylinder is extremely troublesome, and even after adjusting the height, the upper end surface of the outer cylinder must be tightly closed to prevent dirt from flowing in. The idea was proposed in view of the above, and its gist is that by making the male screw part formed on the outer circumferential surface of the inner cylinder part of the lower part, the inner cylinder can be easily tightened even after being buried underground. The height can be increased and easily changed.
以下本考案を図面の実施例について説明すると、1は下
端に下部枠2を有する外筒体で、該外筒体1の内面全周
には比較的ピッチの荒い雌ネジ部3を形成する。The present invention will be described below with reference to the embodiments shown in the drawings. Reference numeral 1 denotes an outer cylindrical body having a lower frame 2 at its lower end, and a female screw portion 3 with a relatively coarse pitch is formed on the entire inner circumference of the outer cylindrical body 1.
該外筒体1は上端面が開放し、上端部分には径方向に相
対するように外側に延出する鍔状固定部4を設け、該固
定部4には二本の受は溝5,5を形成する。The outer cylindrical body 1 has an open upper end surface, and is provided with a flange-shaped fixing part 4 extending outward so as to face each other in the radial direction. form 5.
上記外筒体1に上から螺合される内筒体6は、上端部に
僅かに拡径する蓋受部7を設け、該内筒体6の下方部分
の外周面には前記外筒体1の雌ネジ部3に螺合する雄ネ
ジ部8を設ける。The inner cylinder body 6, which is screwed onto the outer cylinder body 1 from above, is provided with a lid receiving part 7 having a slightly enlarged diameter at its upper end, and the outer peripheral surface of the lower part of the inner cylinder body 6 is A male threaded portion 8 is provided to be screwed into the female threaded portion 3 of 1.
この雄ネジ部8は、内筒体6の全長のほぼ3分の1程度
でよい。This male threaded portion 8 may be approximately one third of the total length of the inner cylinder body 6.
したがって、外筒体1に内筒体6を上から嵌め付けると
、雄ネジ部8に雌ネジ部3が螺合し、内筒体6を回転す
ることにより該内筒体6が外筒体1に次第に嵌入し、内
筒体6の蓋受部7の上下位置を自由に調節することがで
きる。Therefore, when the inner cylinder body 6 is fitted onto the outer cylinder body 1 from above, the female thread part 3 is screwed into the male thread part 8, and by rotating the inner cylinder body 6, the inner cylinder body 6 is attached to the outer cylinder body. 1, and the vertical position of the lid receiving part 7 of the inner cylinder body 6 can be freely adjusted.
外筒体1の上端に取付けて該外筒体1の内部に土砂が流
入するのを防ぐリング材9は、図面の実施例では半円弧
状で左右の先端に外側に延出する耳部10を設け、該耳
部10に通孔11を開設する。In the embodiment shown in the drawings, the ring member 9 attached to the upper end of the outer cylinder 1 to prevent dirt from flowing into the outer cylinder 1 has ears 10 extending outwardly at the left and right ends in a semicircular arc shape. is provided, and a through hole 11 is opened in the ear portion 10.
したがって内筒体6を螺合させた外筒体1の上端面に上
記したリング材9,9を左右から装着し、各リング材9
の内面9′を内筒体6の上方外周面に当接させるととも
に、各リング材9の耳部10を前記外筒体1の上端面に
形成した固定部4の上面に載せ、各リング材9の隣り合
う耳部10.10の上面に一連に座金材12を当てがい
、座金材12に形成した小孔13に上から通すボルト1
4を通孔11及び受は溝5に通してナツト15を強く止
着することにより、座金材12とリング材9及び外筒体
1とが強固に一体的になる。Therefore, the above-mentioned ring materials 9, 9 are attached from left and right to the upper end surface of the outer cylinder 1 to which the inner cylinder 6 is screwed, and each ring material 9
The inner surface 9' of the inner cylinder body 6 is brought into contact with the upper outer peripheral surface of the inner cylinder body 6, and the ears 10 of each ring member 9 are placed on the upper surface of the fixing part 4 formed on the upper end surface of the outer cylinder body 1. The bolts 1 are placed in series on the upper surfaces of the adjacent ears 10 and 10 of the bolts 1, and are passed through the small holes 13 formed in the washers 12 from above.
4 is passed through the hole 11 and the groove 5, and the nut 15 is firmly fixed, so that the washer material 12, the ring material 9, and the outer cylindrical body 1 are firmly integrated.
そして各リング材9の内面9′は内筒体6の外周面に圧
接しているのであるが、各リング材9の下面外周に下向
きの隆出部16を形成して外筒体1の外周面に当接させ
ればリング材9を外筒体1の上端面に更に安定して保持
することができる。The inner surface 9' of each ring member 9 is in pressure contact with the outer peripheral surface of the inner cylindrical body 6, and a downward protrusion 16 is formed on the outer periphery of the lower surface of each ring member 9, so that the outer periphery of the outer cylindrical body 1 is If the ring material 9 is brought into contact with the surface, the ring material 9 can be held more stably on the upper end surface of the outer cylinder 1.
本案は上記のようにしてなり、特にリング材9が二つ側
御状構造なので組付けや取外しが極めて簡単であって地
中に設置した状態においては、外筒体と内筒体との隙間
に上から土砂などが流入することがなく、且つ路面舗装
その他の理由によって内筒体の高さを調節する場合には
内筒体6を回転するだけで上下位置を調節することがで
き、また雄ネジ部がリング材に接触するようなこともな
い。The present invention is constructed as described above, and in particular, since the ring material 9 has a two-sided structure, it is extremely easy to assemble and remove, and when installed underground, the gap between the outer cylinder and the inner cylinder When adjusting the height of the inner cylinder due to road pavement or other reasons, the vertical position can be adjusted simply by rotating the inner cylinder 6. There is no possibility that the male threaded part will come into contact with the ring material.
したがって外筒体及び内筒体の上方部分の土砂などを除
去する必要もなく、極めて簡単に内筒体の上下位置を変
更することができる。Therefore, there is no need to remove earth and sand from the upper portions of the outer cylinder and the inner cylinder, and the vertical position of the inner cylinder can be changed very easily.
また内筒体の高さ変更の場合にはリング材を外す必要が
ないばかりでなく、高さ変更時にも外筒体と内筒体との
間に土砂が流入することもなく、更にリング材が内筒体
の外周面に当接しているので内筒体が左右に振れるよう
なこともない。In addition, when changing the height of the inner cylindrical body, there is no need to remove the ring material, and when changing the height, dirt does not flow between the outer cylindrical body and the inner cylindrical body, and the ring material Since the inner cylinder is in contact with the outer peripheral surface of the inner cylinder, the inner cylinder does not swing from side to side.
したがって、高さ調整が自在であり、且つ高さ調節の作
業が著しく簡単な実用的効果の高い地中弁用弁筺を提供
するものである。Therefore, it is an object of the present invention to provide a valve casing for an underground valve which is height adjustable and has a highly practical effect in which the work of height adjustment is extremely simple.
