Description

The present invention is a solvent permeation preventing layer, scratch prevention layer or the like, a saddle for multiple layers cladding tube, polyethylene solvent permeation preventing cladding tube such cladding tubes of which between the coating layer is to be particularly polymerized in the non-adhesive having a coating layer of The present invention relates to a method of wearing the attached faucet.

  In order to supply water from a water distribution pipe to a detached house or an apartment house, a water faucet must be attached and branching to a branch pipe. However, recent resin pipes are also planned to be installed in places where the installation environment is bad, such as places that may be contaminated by organic solvents such as gasoline and kerosene, and places that have already been contaminated. Therefore, cladding pipes designed to protect water pipes have been used.

Conventionally, water supply from a water distribution pipe to a branch pipe is branched by forming a perforated portion in the water distribution pipe and providing a water faucet to which the branch pipe is connected. A waterproof seal is attached between the perforated part and the mounting surface of the water faucet so that the water faucet and the perforated part are sealed.

Regarding the sealing structure between the water pipe perforation and the mounting surface of the water faucet, for example, Patent Document 1 discloses that the water faucet is connected to the cylindrical mounting portion connected to the saddle of the water cock with a saddle. The water guide pipe is fitted with an insulating collar, the mounting portion, the water guide pipe, and the insulating collar are prevented from rotating relative to each other by a detent means, and an insulating fixing ring is screwed to a portion in contact with the saddle. It is described.

Further, in Patent Document 2, positioning is performed using a diameter-expanded metal member formed in a divided cylindrical shape having a pipe support surface that fits a peripheral wall surface in a perforated portion to which a water faucet is attached, and having a seal packing member attached to a lower portion. Proposals have also been made to lock and efficiently attach the water faucet to the piping.

However, if the branched water distribution pipe is a water distribution pipe without a covering layer, the sealing performance of the saddle mounting surface is maintained by the water stop packing, but it is necessary to protect the water distribution pipe from the laying environment by the covering layer as described above. In some cladding tubes, especially cladding tubes where the coating layer is not fixed, when drilling a branch hole or fastening a saddle with bolts and nuts, the inner tube surface of the cladding tube and the coating layer, or between the coating layers There may be misalignment between these parts, and water leakage from this part is likely to occur, and furthermore, since processing accuracy is required for the saddle part, processing costs and material costs increase, and in terms of material costs as well There is a problem that it is disadvantageous in terms of work efficiency.

The present invention can be applied to cladding having a coating layer of a plurality of layers, the durability of the water diversion plug mounting portion to ensure sealing performance, attachment of the diversion stopper mounting process can reliably be to water pipes It is intended to provide a method.

  The present invention is intended to address the above-described problems, and performs marking by piercing from the skin layer to the inner tube surface of the cladding tube at the water-dividing hole drilling position. The inner pipe surface of the cladding pipe is exposed by cutting off the coating layer of the length portion that leaves a predetermined space on both sides of the water faucet saddle width. And the water stop packing of the water faucet were made to adhere directly.

Moreover, by marking with thorns perforated by punching a punch having a hollow cavity of about 3 to 10 mm, even cladding having a coating layer of a plurality of layers, minute inner tube surface of the cladding tube through the cover layer The water hole drilling position can be clearly marked, and the cut removal part of the coating layer is attached to the inner pipe of the cladding pipe with a water faucet saddle width and a length that leaves a space of approximately 10 mm on both sides, With respect to the upper surface layer, each covering layer portion of a length portion that leaves a space of about 25 mm on both sides of the length width of the lower surface layer was further provided.

Furthermore, after completing the fitting of the water faucet with a saddle to the inner pipe of the cladding tube, the drilling of the water dividing hole, and the fitting of the branch pipe, the fitting part of the water cock with the saddle of the inner pipe of the cladding pipe, the branch pipe Each of the fitting parts of the fitting member fitting part is supplemented with a prevention layer peeled off by wrapping a nylon tape with solvent penetration resistance, and further, a solvent penetration prevention sheet is attached to the water stopcock with saddle and Cover the branch pipe with a solvent permeation prevention sheet from the side of the cladding tube, superimpose and fold the end, stop the folded end with nylon tape, and allow the solvent permeation prevention sheet to have a margin. The outer periphery was fixed by winding with nylon tape.

The present invention, since the structure described above, even in cladding having a coating layer of a plurality of layers, it is possible to position the diversion hole punching position exactly, when drilling for generating twist or deviation in the coating layer The influence of external force such as rotation was eliminated in advance, and the inner surface of the cladding tube and the water shut-off packing of the water faucet were in direct contact, ensuring the durability and sealing performance of the water faucet mounting part. Is.

In addition, the cut removal portion of the covering layer is set to a length that leaves a water faucet saddle width and a space of about 10 mm on both sides of the inner tube of the covering tube, and the upper surface layer has both the above-mentioned length width of the lower surface layer. By making each coating layer part of a length part that leaves about 25 mm of space on the side, the durability and sealing performance of the water faucet mounting part are improved without impairing the protective function of the cladding tube of each coating layer. I was able to.

In addition, after completing the installation of the water faucet with saddle on the inner pipe of the cladding tube, drilling of the water distribution holes, and fitting of the branch pipe, the fitting part of the water faucet with saddle on the inner pipe of the cladding pipe and the branch pipe The inner pipe of the cladding tube at both ends of the water faucet with a saddle is used to complement the prevention layer that has been peeled off by wrapping a nylon tape with solvent penetration resistance around each fitting portion of the fitting member fitting portion. Even if the solvent intrudes from the gap at the edge of the upper surface layer that has been peeled off by the nylon tape being wound up to the step portion from the upper surface layer of the space of approximately 25 mm each where the lower surface layer exists, Contact with the inner tube of the cladding tube can be prevented.

That is, when the nylon tape is wound around the joint step portion by leaving a seam step space of approximately 25 mm on both sides of the lower surface layer, after the nylon tape is wound around the remaining step space, Since it reaches the upper surface layer, the gap caused by the difference in level of the step becomes only one layer thickness, and the nylon tape wound around the remaining step space portion forms an adhesion layer with the lower surface layer, so that the solvent enters. Is blocked in a double or triple manner.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a cladding tube having two layers for mounting a water faucet with a saddle. A first coating layer 12 for preventing penetration of solvent and the like, and further a second coating layer 13 for preventing scratches and the like covering the surface thereof are coated.

First, as shown in FIG. 3, the saddle-equipped faucet 2 with the top cap 21 removed is contacted to determine the mounting position of the saddle-equipped faucet, and the saddle-equipped faucet is inserted through the drilling machine. The provisional marking 3 is made from the upper part through the two water passage holes 22 by appropriate means to the water hole drilling position.

  Further, the width of the fastening saddle 23 of the water faucet 2 with saddle 2 and the length position in which a space of approximately 10 mm is left on both sides thereof are determined with respect to the cladding tube 1, and the cut mark reaching the first coating layer 12 Markings 32a and 32b, and then a length position for leaving a space of about 25 mm on both sides of the lengths of the markings 32a and 32b is determined. , 33b.

  With respect to the coated tube after the marking, the punching punch 4 having a hollow space at the position of the temporary marking 3 is used to penetrate the inner tube surface 11a of the coated tube from the second coating layer 13 serving as the skin layer. Marking 31 by drilling is performed.

As shown in FIG. 5, the punch 4 having a hollow space has a hollow space 41 of about 3 to 10 mm, and the inner tube of the coated tube from the second coating layer 13 to the center by placing the marking 31. A hollow hole of about 3 to 10 mm reaching the surface 11a is formed. Since the inner tube surface 11a of the cladding tube, which is a polyethylene tube, is usually black, the marking point 31a of the marking 31 has a clear black dot display through this hollow hole. Needless to say, the marking 31 may be set by other appropriate means such as cutting with a blade without using the punch 4. Further, the marking point 31a may be marked with white magic or the like without being displayed as a black dot.

  Next, the first coating layer 12 and the second coating layer 13 are linearly cut together in the length direction of the marked lines 32a to 32b set in the cladding tube 1, and then the marking line 32a is formed on the outer circumferential surface of the cladding tube 1 When cutting along the outer peripheral surface of the cladding tube 1 with respect to the marked line 32b, the first coating layer 12 and the second coating layer 13 and the inner tube 11 of the cladding tube are not fixed. The covering layer 12 and the second covering layer 13 can be easily peeled off from the inner tube 11 of the covering tube.

Further, the second covering layer 13 is cut in a straight line in the length direction of the markings 33a to 33b by the cut mark line reaching the second cover layer 13, and then the mark line 33a is cut along the outer peripheral surface of the cladding tube 1. At the same time, if the marking line 33b is cut along the outer peripheral surface of the cladding tube 1, the first coating layer 12 and the second coating layer 13 are not fixed, so the second coating layer 13 can be easily removed from the cladding tube 1. It can be peeled off. The cut of the coating layer can be efficiently performed by using a known coating layer cutter W as shown in FIG. In addition, about peeling removal, the 1st coating layer 12 and the 2nd coating layer 13 may be cut together, may be cut separately, and the cutting method may be free.

  As described above, the length of the coating layer of the cladding tube 1 that leaves a predetermined space on both sides of the water faucet saddle width, and the upper surface layer of the coating layer 1 further has a predetermined space on both sides of the length width of the lower surface layer. After the removal of the covering layer of the length portion leaving the mark around the marking point 31a, the water stopcock with saddle 2 is attached so that the water stop packing of the water faucet is directly adhered to the cut removal portion. Is attached to the inner tube 11 of the cladding tube.

  After the water faucet 2 with a saddle is attached to the inner pipe 11 of the cladding tube, a perforator (not shown) is inserted through the water passage hole 22 of the water faucet 2 with a saddle to perforate the water faucet from above. The branch pipe 14 fitted to the fitting member 24 is joined.

  As described above, when the saddle-equipped water faucet 2 is attached to the inner pipe 11 of the cladding tube, the water-dividing holes are drilled, and the branch pipe 14 is joined, the water-dividing water with saddle of the inner pipe 11 of the cladding pipe is completed. As shown in FIG. 9, a first covering layer peeled off by wrapping a nylon tape 5 having solvent penetration resistance as shown in FIG. 9 around the fitting portion of the stopper 2 and the fitting member fitting portion of the branch pipe 14. Complement 12

  After winding the nylon tape 5 around each bonded portion, the solvent penetration preventing sheet is placed on the saddle-equipped water faucet 2 and the branch pipe 14 including the end of the second coating layer 13 from which the solvent penetration preventing sheet 6 has been peeled off. Covered from the cladding tube side, superposed and folded the end portion 61, and the folded end portion is fastened with nylon tape, and the solvent permeation prevention sheet is provided with a margin of 7 and the outer periphery of the envelopment is covered with nylon tape 51. It is wound up and backfilled.

  The method for attaching a water faucet with a saddle to a cladding pipe according to the present invention is a polyethylene pipe having excellent seismic resistance due to the necessity of supplying water from a water distribution pipe to a detached house or an apartment house in accordance with the demand for housing construction. However, polyethylene with low solvent resistance is planned to be installed in places where there is a possibility of contamination by organic solvents such as gasoline and kerosene and places that have already been contaminated. Since a coated tube that protects the tube with a coating layer is used, it is essential to install a water faucet with a saddle against this, and there is a risk of core misalignment by attaching the water faucet easily and steadily. Therefore, the present invention has a high utility value on the water supply industry.
