本考案は防水装置の脱落防止器具に係り、特に管路口内
に取付けられている防水装置が管路口外へ脱落すること
を防止する防水装置の脱落器具に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a falling-off prevention device for a waterproof device, and more particularly to a falling-off device for a waterproof device that prevents a waterproof device installed in a pipe port from falling out of the pipe port.
従来、ケーブルを布設した管路口内にはマンホールに対
する防水対策として管路口内周面とケーブル外面との間
隙をシールする防水装置を設置することが行われている
。BACKGROUND ART Conventionally, as a waterproofing measure for a manhole, a waterproofing device is installed inside a conduit entrance where a cable is laid to seal a gap between the inner circumferential surface of the conduit entrance and the outer surface of the cable.
しかし、この防水装置は防水コンパウンドを２枚の締付
板によりはさんだものを管路内に挿入しただけなので、
管路内の水圧が上がったりあるいはケーブルの熱膨張に
よりマンホール側に押し出され脱落することがある。However, this waterproofing device simply inserts the waterproofing compound between two clamping plates into the pipe.
If the water pressure inside the pipe increases or the cable thermally expands, it may be pushed out toward the manhole and fall off.
本考案は、このような防水装置の脱落事故を防止するた
めになされたもので、管路口内に設置された防水装置の
移動を簡単に押えうる防水装置の脱落防止器具を提供す
ることを目的とする。The present invention was developed in order to prevent such accidents of waterproofing devices falling off, and the purpose is to provide a fall prevention device for waterproofing devices that can easily prevent the movement of waterproofing devices installed in the pipe entrance. shall be.
以下、本考案を図示例につき説明する。The invention will now be explained with reference to illustrated examples.
第１図は本考案の一実施例を示している。FIG. 1 shows an embodiment of the present invention.
図において、脱落防止器具１はリング２とこのリング２
の周囲８カ所に配置された押えボルト３（図には１カ所
のみを示し、他の７カ所は配置位置のみを１点鎖線で示
しである。In the figure, the fall prevention device 1 includes a ring 2 and a ring 2.
Holding bolts 3 are arranged at eight locations around the (only one location is shown in the figure, and only the placement positions of the other seven locations are indicated by dashed lines).
）とからなる。リング２は、第２図に示されるように防
水装置４を取付けた管路口５の口径より小さい外径を有
しており、適当な機械的強度を備えた金属又はプラスチ
ックにより成型されている。). As shown in FIG. 2, the ring 2 has an outer diameter smaller than the diameter of the pipe port 5 to which the waterproof device 4 is attached, and is molded from metal or plastic with appropriate mechanical strength.
押えボルト３はリング２にねじ込まれ径方向に進退自在
に装着されている。The holding bolt 3 is screwed into the ring 2 and is attached so as to be freely movable in the radial direction.
また押えボルト３には止めナツト６が嵌合されている。Further, a locking nut 6 is fitted into the holding bolt 3.
上記構成の脱落防止器具１は第２図に示されるように管
路口５内に挿入配置された防水装置４にに対してマンホ
ール側即ち管路口の開口部側に配置される。As shown in FIG. 2, the fall prevention device 1 having the above structure is placed on the manhole side, that is, on the opening side of the pipe port, with respect to the waterproofing device 4 inserted into the pipe port 5.
なお、防水装置４は防水コンパウンド７及びこれを両側
よりはさむ締付具８，９により構成されている。The waterproofing device 4 is composed of a waterproofing compound 7 and fasteners 8 and 9 that sandwich this from both sides.
そしてリング２に取り付けられている各折えボルト３を
外方に延出させて管路口内壁に当接させ、器具１全体を
管路に固定するようにする。Each bending bolt 3 attached to the ring 2 is extended outward and brought into contact with the inner wall of the conduit opening, so that the entire instrument 1 is fixed to the conduit.
したがって、防水装置４がマンホール側に移動してきて
もリング２によってその移動を押えるから脱落を防止で
きることとなる。Therefore, even if the waterproofing device 4 moves toward the manhole, the ring 2 suppresses the movement, thereby preventing it from falling off.
なお、止めナツト６は押えボルト３をリング２に堅固に
固持する役目をなす。Note that the locking nut 6 serves to firmly fix the presser bolt 3 to the ring 2.
なお、上記実施例ではリング２を連続する輪状としたが
、本考案はこれに限定せず、周囲の１カ所を切断するか
もしくは２つ割りとした構造とすることにより任意の位
置でケーブルに嵌め込みうるようにして既存のケーブル
布設線路にも適用できるようにしてもよい。In the above embodiment, the ring 2 was made into a continuous ring shape, but the present invention is not limited to this, and the cable can be attached to any position by cutting one part of the periphery or dividing it into two parts. It may also be possible to fit it in so that it can be applied to existing cable laying lines.
以上、本考案に係る防水装置の脱落防止器具によれば、
リングとこのリングの周囲数カ所に配置された押えボル
トとを有するものであることによリ、簡単に防水装置の
脱落を防止することができる。As mentioned above, according to the fall prevention device for waterproofing device according to the present invention,
By having a ring and holding bolts arranged at several places around the ring, it is possible to easily prevent the waterproof device from falling off.
