Abstract

Branch pipe sockets that can be used in common for these pipe materials may have uneven or smooth surface shape depending on the type of sewage pipe among existing new sewage pipes or previously installed sewage pipes, and have the same pipe inner diameter but different pipe thicknesses and different pipe inner diameters. There was a problem in the watertight method of the attachment device.

According to the present invention, the watertight method of blocking the inflow of water flowing from the outside of the pipe and the outflow of the inside of the pipe and the branch pipe inside even if the water is sealed to only one inside of the pipe. It is possible to prevent the thickness of the protruding pipe of the inner washer inserted into the inner side of the branch pipe thinly, and thus it is a watertight method of the branch pipe socket attachment device, which has the advantage that the pipe inlet hole can be drilled relatively small. If the pipe thickness is different from the same and the pipe inner diameter is different, it is a very useful invention because it is a watertight method of branch pipe socket attachment device that can be commonly used by replacing only one auxiliary ring washer.

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 selects an inner washer (split washer) in which the pipe is connected to the inlet (outlet) and the tension line is connected to the inner surface of the inlet. Branch socket attachment device that attaches the bolt to the bolt hole formed in the branch socket inner projection by attaching the packing with the bottom surface of the branch socket having the curved surface facing the pipe outer surface and attaching the branch socket to the tightening part of the inner washer. (See FIGS. 3A and 3B), there is no problem of watertightness when the outer surface of the pipe is smooth, but it cannot be used when the outer surface of the pipe is uneven, such as a double wall sewer pipe or PVC DC pipe. If there is a problem, and if the dirt passes, such as sewage pipes, there is a problem in that the tightening portion for screwing the inner side of the branch socket protrudes, thereby causing the dirt. Korean Utility Model Registration No. 5712 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 (see FIGS. 4A, 4B, and 4C) and on the outer surface of the pipe. Since there is a packing, there is a problem that cannot be used if the outer surface of the pipe is uneven like a double wall sewer pipe, a PVC DC pipe. In Japanese Patent Application Laid-Open No. 4-203584, a technique of pressurizing watertight packings by tightening the water pipes by rotating the inclined portion of a nibble-shaped water pipe short pipe on the saddle. Is larger than the standard or slanted, there is a problem with the fastening and watertight.

The present invention is to solve the problems of the prior art described above, the packing is not in the pipe outer surface, but the pipe surface is smooth pipe surface, as well as a branch that is watertight even if the outer surface of the pipe, such as double-wall sewer pipe or PVC DC pipe uneven shape. The watertight method of the branch socket attachment device and the inflow hole drilled in the pipe do not need to be precisely drilled vertically, and even if it is irregular and relatively large in the garden rather than a hole cutter, such as a jig saw, In addition, the technical problem is the development of a packing that is watertight with only one watertight packing of the inner surface of the pipe from the inflow water flowing from the outer surface of the pipe to the outflow water flowing from the inner surface of the pipe and the branch pipe.

Another object of the present invention is a watertight method of a branch pipe socket attachment device that can be commonly used by replacing only one auxiliary ring washer, even though the pipe inner diameter is the same and the pipe thickness is different.

Insert the inner washer into the inlet hole from one side of the inlet hole drilled in the pipe, and hang the inner washer at the periphery of the inner surface of the inlet hole. In the attachment device for fastening and attaching, the packing for watertightness is a packing inner surface having a curved surface that is in close contact with the entire inner circumference of the pipe inlet hole and a packing outer surface which is the top of the packing in the same direction as the tubular packing center of the pipe inlet hole side shape. The inner and outer surfaces or the lower surface of the branch tube pipe which is formed integrally with the bottom of the saddle tube and is formed integrally with the bottom of the saddle and moves up and down through the center of a separate saddle and moves up and down through the center of a separate saddle tube and the packing of the tube tube shape. Pressing or pressing, bonding, welding, inserting, injection, desorption, etc. Including a branching pipe integrally, the inner surface of the trumpet-shaped packing interposed between the periphery of the inner surface of the pipe inlet and the inner washer may be sealed by screwing with the inner surface of the saddle or the branching pipe, or the thickness of the branching pipe may be different due to the pipe thickness being different. Pressing the saddle upper surface from the outer side of branch pipe according to the pipe thickness, pressurizing only the inner surface of the fallopian tube-shaped packing between the inner periphery of the pipe inlet hole and the inner washer during the second tightening, the inflow from the outside of the pipe and the internal sewage of the pipe and internal sewage of the branch pipe It becomes a watertight method of the branch pipe socket attachment device, characterized in that the effluent of the watertight.

The branching pipe is preferably a structurally strong material (rigid material) when integral with the outer surface and the lower branching pipe inner or outer surface of the fallopian tube-shaped packing, and the packing is compressive force (elasticity), cushioning force, It is a soft synthetic resin or rubber considering the elongated property, durability, and corrosion resistance to sewage. In order to integrate the branch pipe with the branch pipe, the outer surface, which is the upper end of the fallopian tube, is pressed by the stainless steel band or spring to the lower inner surface or the outer surface. In case of integrating by attaching with a special adhesive, integrating by melting by heating, integrating by welding with welding agent, and inserting or integrating the outer surface part of the upper end of the packing into the concave-convex part in the groove formed on the lower surface of the branch pipe or the projection rotated 360 °. It could be. In addition, the second branch of the branch pipe and the lower and inner tube or the bottom of the fallopian tube-type packing, such as the method of injecting and integrating the lower inner and outer surfaces or the lower surface of the branch pipe with a soft material and the above-mentioned pressing (or pressing) and insertion method It may be integrated in a detachable form that is attached to the outer surface portion, which is the upper end of the packing as necessary to integrate or separate as needed.

In addition, the lower part 289 of the ring (288) shape of a ring (Ring; 288) is formed on the top of the outer surface 71 of the packing 70 in the form of a fallopian tube. It may be formed integrally with the bottom of the branch pipe socket or the bottom of the branch pipe.

If necessary, the integration method may be utilized at one end of the fallopian tube-type packing, and at the end of the packing center.

Further, even if the inner surface of the tube and the packing inner surface portion of the fallopian tube is bonded with an adhesive, and the one or more inner washers are pressed, the whole or part of the inner tube portion of the fallopian tube may be pressed.

At this time, grooves or corrugations are formed in the inner and outer surfaces of the central portion of the tube in the fallopian tube-shaped packing by one or two turns or more, and the height of the pipes is adjusted by bending at the grooves or the corrugations at 360 ° so that the curvature of the inner surface of the pipe is different. When the inner washer curvature to be in close contact with this is also the same curvature as the different curvature of the inner surface of the pipe, even if the inner surface of the fallopian tube is press-sealed between the inner surface of the pipe and the inner washer, the height is varied by bending in the groove or crease in the center of the fallopian tube type. It is also a watertight method of the branch pipe socket attachment device.
