Description

  The present invention relates to a water stop fixing device for pipes or cables, and in particular, a sheath pipe embedded in a concrete wall or the like and a water stop fixing device for pipes or cables, or a pipe or cable directly inserted into a concrete wall through-hole. It relates to a water stop fixing device.

  Conventionally, when water pipes such as gas pipes, water and sewage pipes, electric pipes, optical cables, communication cables, etc. are embedded in concrete walls, etc. In some cases, an annular water-stopping packing material made of water-expandable rubber or elastomer material or non-water-expandable rubber or elastomer is integrally formed.

JP 2005-282863 A Japanese Patent Publication No.7-114530

  In Japanese Patent Application Laid-Open No. 2005-282863, an annular water-stopping packing material made of a water-expandable rubber, an elastomer material, a non-water-expandable rubber, an elastomer material, or the like that is mounted between a pipe line and a sheath tube is integrated. It was what was molded.

  For this reason, the mounting workability was poor, the material strength was weak, the water pressure was lost and it flowed into the sheath tube, there was no water-stopping effect, and dirt and debris on the adhesive surface remained.

  Moreover, in the above-mentioned Japanese Patent Publication No. 7-114530, the semi-vulcanized rubber is wound around the outer peripheral surface of the pipe opening portion of the wire material inserted into the pipe, and ring-like shapes are respectively formed on both ends of the semi-vulcanized rubber. By attaching the packing, closing the space between the packings in the pipeline, and filling the space surrounded by the packing, semi-vulcanized rubber, and the wall surface of the pipeline with the water intake material forming material and curing it. The semi-vulcanized rubber was in close contact with the wire, and the pipe was stopped.

  Also in this case, winding of semi-vulcanized rubber and filling of the pipe water intake material forming material is poor and workability such as curing is weak, the material strength is weak, it flows into the sheath pipe under water pressure, there is no water stop effect, The dirt and debris on the adhesive surface remained.

  Further, in the conventional example shown in FIG. 8, the sheath tube 2 is inserted into the tank steel plate 1, the cable 3 is inserted into the sheath tube 2, the fillers 91 and 92 are filled into the sheath tube, and the bolts 8 are engaged. The structure was stopped and sealed with the sealing material 93, but the adhesion was poor due to deterioration of the material.

The present invention is configured as follows to solve the above-described problems.
A split annular elastic body is sandwiched between two split annular flanges, and a bolt inserted between the split annular flanges is tightened with a wrench to compress and deform the split annular elastic body, so that the inner surface of the sheath tube or the concrete wall It is characterized in that it is fixed to the inner surface of the through hole in a watertight state, and the divided annular flange and the divided annular elastic body are shifted to be attached to an existing pipe line or cable, and are inserted into a sheath pipe or a concrete wall through hole, Then, the divided annular flange and the bolt inserted into the divided annular elastic body are tightened to compress and deform the divided annular elastic body so that the pipe or cable is in a watertight state on the inner surface of the sheath pipe or the inner surface of the cochleet wall through hole. The split ring is characterized in that the two split annular flanges are formed of metal or reinforced plastic, and the split ring is sandwiched between the split annular flanges The elastic body is composed of a laminated body made of butyl rubber, elastomer material, or water-expandable rubber, and the cable is held in the concrete wall through hole formed in the manhole or the shaft concrete wall A pipe or cable characterized in that when the divided elastic body is inserted and pressed, the peripheral edge of the divided elastic body is three-dimensionally deformed on the inner surface of the through hole of the concrete wall and held in a watertight state. A water stop fixing device is provided.

  In the pipe or cable water stop fixing device of the present invention, the cable is inserted into the split annular elastic body sandwiched between the two split annular flanges, and then temporarily fixed into the sheath pipe fixed to the concrete wall. Then, the divided annular elastic body can be compressed and deformed by a simple operation of sequentially tightening a plurality of bolts inserted between the annular flanges using a wrench, and can be fixed in a watertight manner to a pipe line or a concrete wall through hole. it can.

  Further, since the split annular elastic body is composed of a laminated body made of butyl rubber, elastomer material, or water-expandable rubber, the annular elastic body is compressed and deformed by tightening a plurality of bolts inserted between the split annular flanges. Body butyl rubber, elastomer material, or water-expandable rubber is pressed against the inner surface of the sheath tube or the inner surface of the through hole of the concrete wall, and the annular butyl rubber on the inner periphery of the annular elastic body is pressed against the pipe line or cable and fixed. Can be kept in a watertight state.

  Further, when a split annular elastic body that holds a cable is inserted and pressed into a concrete wall through hole formed in a manhole or a vertical concrete wall, the peripheral edge of the divided annular elastic body is the inner surface of the concrete wall through hole. Therefore, it is used as a three-dimensional sealing material.

It is a longitudinal direction longitudinal cross-sectional view of the water stop fixing apparatus attached to the pipe line. FIG. 2 is an exploded perspective view of FIG. 1. It is a perspective view of the water stop fixing device attached to the tank. It is a front view of a water stop fixing device. It is a perspective view of the cable inserted in the concrete wall. It is a longitudinal cross-sectional view of the water stop fixing apparatus attached to the pipe line.
