Korean Utility Model Registration No. 54114 (branch socket attachment device), Korea Utility Model Registration No. 5812 (socket attachment device with manned wire) and Japanese Patent Application Laid-Open No. 4-203584 (branch coefficient: On July 24, 1992, the Republic of Korea Utility Model Registration No. 54114 selected the inner washer (split washer) in which the pipe was connected to the inlet (outlet) and the tension line was connected to the inside of the inlet. Branch sockets with hooks and the outer surface of the branched sockets face the pipes, attach the packings, insert the bolts into the bolt holes formed in the branch socket inner projections, and tighten the joints with the inner washers to attach the branch sockets to the outer pipes. If the external surface of the pipe is smooth, there is no problem in watertightness, but there is a problem that cannot be used when the external surface of the pipe is irregular, such as a double wall sewer pipe or a PVC DC pipe. When dirt passing as a sewage pipe has got a fastening portion for screwing the inner surface of the branch socket protrudes had this problem, because more waste is taken to have a plurality of screw had inconvenience in construction. Korean Utility Model Registration No. 5512 has a problem that the inner washer (cutting washer) has a rectangular shape, so that the inner washer of a completely circular shape cannot be spread over the inner surface of the pipe and there is a packing on the outer surface of the pipe. If the outer surface is irregular shape, there is a problem that can not be used. Japanese Patent Application Laid-Open No. 4-203584 is a technique for tightening the packing of water pipes by tightening the water pipes by rotating the inclined portion of the nipple-shaped water pipe short pipe on the saddle. If the size is larger than the standard or beveled obliquely, there is a problem with the fastening and watertight.

The present invention solves the problems of the above-described branch pipe socket attachment device, but the lower part of the branch pipe is usually drilled into the pipe inlet hole to insert the connection pipe on the side of the pipe, in the present invention does not enter the lower branch pipe in the inlet hole It is a technical task to achieve the development of the structure of the branch pipe socket attachment device that the watertight pipe shape is integrated with the bottom of the branch pipe, which is integrated with the branch pipe bottom, as the lower part of the branch pipe. The technical task is to develop a structure in which the saddle bottom having the same curvature as the outer surface of the inlet hole does not deviate from the outer surface of the inlet hole periphery and stably moves back and forth, and to the left and right of the inlet hole periphery. Even if the size of the inlet hole drilled in the hole is smaller than usual, It reduced structural stability due to the piping inlet hole punched in the pipe fastening of the mounting device, and the development of road branch tube socket which is water-tight device relatively large diameter is used to connect a pipe aspect.

Insert the inner washer 300 into the inlet hole at one side of the inlet hole 650 drilled on the side of the pipe 600, and hang the inner washer 300 at the periphery of the inlet hole inner surface 620 and at the periphery of the outer inlet of the pipe inlet 610. Attach the branch socket to the inner washer on the inner side of the pipe by tightening and screwing the inner socket of the branch socket and the screw of the inner washer which is hung on the inner surface of the branch socket. When plugging the pipe 700 into the branch socket, the branch socket has a curved saddle 100 and a protruding tube 150 integrated therewith, and consists of a branch pipe 200 moving up and down in the protruding tube. The packing for watertightness includes a packing inner surface 73 having a curved surface that is in close contact with the entire periphery of the pipe inlet hole 620 and a tubular packing center portion 72 having a pipe inlet hole side shape. In groove (74) An inner and outer surface or the lower surface of the branch pipe and the fallopian tube shape formed of a bellows-shaped packing 70 formed of a packing outer surface 71 formed in the same direction as the upper end of the packing in the same direction as the corrugation 77. By forming a branching pipe in which the packing outer surface 71, which is the upper end of the packing 70, is integrally formed, a packing inner surface 73 in the form of a fallopian tube interposed between the inner periphery of the pipe inlet hole 620 and the inner washer 300. Tighten the inside of the branch pipe or screw the projection pipe or integral with the inner washer, and the pipe thickness is different so that the branch pipe pipe height to match the thickness of the branch pipe pipe from the outer surface of the branch pipe 150 to the branch pipe outer surface of the branch pipe Tighten with the nut 400 fastened to the male screw 290 to pressurize only the inner surface 73 of the fallopian tube-shaped packing between the inner surface 620 of the inner surface 620 of the pipe inlet hole 650 and watertight to be watertight. Branching In the pipe socket attachment device, the tube-shaped packing center portion of the fallopian tube-shaped packing 70 is protruded to the outer surface of the inlet hole 650, and the outer surface portion 71, which is the upper end of the packing, is provided with the lower inner surface 284 of the branch pipe. The packing center portion 72 and the outer surface portion 71 are formed to be biased from the lower side of the branch pipe toward the inner surface of the branch pipe to form the outer diameter of the packing center portion smaller than the diameter of the branch pipe lower outer surface 286 toward the same surface. When the pipe 360 is inserted into the lower part of the inner surface of the branch pipe 270, the screw is tightened or caught, and when the upper surface of the protruding pipe 150 integral with the saddle is tightened with a nut 400 to pressurize the pipe inlet, A protruding pipe 360 is inserted into the packing center portion 72 having a fallopian tube shape and an inner washer penetrating the inside thereof, and thus the lower part of the branch pipe is not connected to the pipe inlet hole. The inner surface portion of the packing 73 is watertight so that the pressure branch tube socket apparatus.

In this case, a plurality of screw holes 190 are formed in the saddle 100 to the outside of the inlet hole. And tightening to the pipe with a vise has the effect of preventing the birds placed on the pipe outer surface 610 to move back and forth, left and right. In addition, the inlet hole 650 of the pipe 600 has a C-shaped cross symmetrical lower surface than the inlet hole to form a cut-out portion 660 that is flat, the pipe inlet to the bottom of the saddle 100 having a pipe outer surface curvature. The C-shaped protruding frame 110, which is flat on the bottom surface, is formed to be symmetrical to each other, and the C-shaped protruding frame 110 protruding on the bottom of the saddle is formed on the pipe. When it is symmetrical to the outer surface of one inlet hole is plugged into the cut portion 660 that is flat and tightened with a nut 400 is a branch pipe socket attachment device that the saddle 100 is securely fixed in place on the outer surface of the pipe.

In addition, the central portion 72 of the fallopian tube-shaped packing 70 rotates the groove 74 or the pleat 77 rotated 360 ° parallel to the lower surface of the branched pipe in addition to the tubular packing. By forming two or more rotations, the height of the pipe is adjusted by bending in the recesses 74 or the pleats 77 at any portion of 360 ° so that the inner curvature of the pipe is different from the curvature, and the curvature on the inner washer that is in close contact with the pipe is also the same as the different curvature of the pipe inner surface. When the inner tube portion of the fallopian tube-shaped packing on the inner washer is press-sealed between the inner surface of the pipe and the inner washer, the height is variable by bending in the groove 74 or the pleat 77 of the central portion of the fallopian tube-type packing 72 It becomes watertight.
