The present invention is an improvement of utility model registration No. 544114 (branch socket attachment device), especially sewage pipe branch pipe joint that flows smoothly even though the branch pipe joint socket (branch socket) is mixed with suspended matter such as sewage and impurities. It's about sockets.

Sewer pipes are connected to the joints of many pipes, and the watertightness and flow should be smooth at each joint. Especially in the case of sewage pipes, the leakage of its contents should be watertight due to soil contamination and environmental damage caused by this, and the infiltration of groundwater due to incompleteness of the joints increases the cost of treatment and the surrounding soil flows into the pipes and obstructs the sewage flow. In addition, damage to installations is caused by sinking the surroundings. Therefore, in the sewage pipe, the seam should be smooth because there is no water-tightness, as well as the love parts such as uneven parts and protrusions on the inner surface unlike water pipes.

Currently, when connecting branch pipes to sewage main pipes, T-shaped pipes, Y-shaped pipes or 9 branch sockets are used.T-shaped pipes and Y-shaped pipes are used to connect the pipes to the grounded pipes. In case of direct branching, make a hole in the main pipe to connect the branch pipe and connect the branch pipe to it, but the connection conditions are much worse than the construction of the T and Y pipes because it must be firmly connected without causing any obstacle to the watertightness and protrusions. The joint is likely to be incomplete.

The reality of branching the branch pipe directly from the sewage main pipe is to connect the branch pipe to the upper surface of the branch pipe socket after attaching the bottom of the branch pipe socket to the inlet port after the inlet hole in the main pipe. Two types are used to attach the branch pipe. In other words, if the main pipe is a fume pipe, a concrete paper pipe socket, if the main pipe is a conduit, a conduit paper pipe socket, if the main pipe is a fume pipe, a concrete paper pipe socket, and if the main pipe is a conduit, In the PVC pipe, the main pipe socket is attached with PVC saddle-shaped paper pipe socket around the inlet through the main pipe and bundled with a mortar, adhesive or iron wire to obtain a watertight seal. By the way, the branch pipe does not protrude in the main pipe, but after installation, the ground pipe socket must not only bury the earth and soil until the bottom of the main pipe due to earth pressure or impact, etc. It is a way.

In the case of different pipe types, even if branch pipes are inserted into the inlet hole of the main pipe without using branch sockets, even if the branch pipes protrude on the inside of the inlet, it is often fixed by the mortar from the outside of the pipe. There is a possibility of depositing PE fertilizer in recent years, but PE bird can be attached by fusion method, but there is a problem in the current method of connecting the branch pipe directly to the sewage main pipe. will be.

Utility Model Registration No. 54114, a declaration of this cause, attaches a split washer with a tension line connected to the outflow hole of the pipe, and hangs it on the inner surface of the outlet hole. The present invention relates to a branch socket attaching device for attaching a bolt to a bolt bulb formed on an inner surface of a protrusion and attaching a branch socket to a main socket by tightening the bolt with a tightening part of a split washer. The wire design can be used as a branch socket for water pipes without impurities or lumps.However, if the soil passes, such as sewage pipes, several uneven parts are formed between several fastening parts projecting on the inner surface of the branch socket. Since the branch socket is exposed to the inner surface and there is a problem of dirt, the branch pipe must be inserted to penetrate into the branch socket inner projection and the split washer tightening part, so the branch socket must be large and the outflow hole is considerably large, which is uneconomical. There is also a problem in the structural safety because a large outflow hole is drilled in the piping. In addition, the branch pipe is connected only 90 degrees to the main pipe is not suitable as a sewer branch pipe socket that requires a branch socket, such as a 60 degree so that the sewage flows easily from the branch pipe to join the main pipe flow.

The purpose of the present invention is to make the flow smoothly because there is no jam obstacle on the inner surface of the branch pipe joint socket and the branch pipe joint in view of the above problems, another purpose is to minimize the size of the fastener, another object In addition to the 90 degree pipe, the purpose is to provide a 60 °, 45 ° angled pipe joint socket attachment device.

Structural feature of the present invention is to connect the split washer to the outflow hole (fastening hole) of the pipe so that it is caught on the inner side of the outlet hole, and the bolt hole formed on the protrusion of the branch socket inner side with the packing with the branch socket bottom facing the outer side of the pipe. When attaching a bolt to the tightening part (female screw) of the split washer and attaching the branch socket to the pipe, the inner part of the branch socket is formed with an extension of the inner part of the projection and the cover part by extending the inner part of the projection washer. By covering the overhanging cover, the sewage flow will be smooth.

In addition, the protrusion cover may be integrated with the branch socket inner surface protrusion, and may be provided separately from the branch socket inner surface so as to have a substantially same inner surface as the inner surface of the branch pipe, or at least to form a streamlined surface so as not to interfere with the sewage flow, and install it on the inner surface of the branch socket.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

Underneath, the projection 25 has a projection inner surface 24 having a diameter smaller than that of the inner surface 27 so that the projection 25 is flush with the inner surface of the branch pipe 81, and the vertical tube projection 36 of the split washer 3 and the bolt thread 41 ) Cover protrusions (23) extending toward the fastening hole (11) is formed, and several bolt holes (26) and tension line holes (28), if necessary, are drilled up and down the protrusions (25).

The protrusion cover 23 covers the projection 25 and the concave-convex portion 37 shape and the bolt screw portion 41 which are inevitably generated as shown in FIG. 7 while tightening the branch socket 2 and the split washer 3. Since the inner surface 24 coincides with the inner surface 81 of the branch pipe, the sewage flow is smoothed. Therefore, the structural effect of the branch pipe fitting socket for the sewer inclined at 90 degrees as well as 60 degrees is very large. . Since the pipe thickness for sewer pipes differs depending on the type of pipe, even if the same nominal diameter, the height of the protrusion cover 23 should be taken into consideration, and the protrusion cover 23 is separately from the protrusion 25 as shown in FIG. It can also be separated. In addition, by forming a protruding frame 22 to enter into the fastening hole 11 under the branch socket 2, the branch socket 2 is fastened to the impact such as external pressure together with the vertical pipe 34 of the split washer 3. Do not let go of the ball (11).
