Description

Branch socket of synthetic resin pipe

The present invention relates to a branched socket structure for connecting a branch pipe to a synthetic resin pipe including a corrugated pipe, and more particularly, a pair of bent grooves are provided at both sides of the socket blade, and a socket having a soft adhesive rubber plate adhered to an upper surface thereof. The socket blade is inserted through the through hole provided on the side of the straight pipe in the folded state, and the upper surface of the socket blade is tightly coupled by the lower cover to the inner circumferential surface of the straight pipe so that the branch pipe can be easily connected to the straight pipe. In addition, the present invention relates to a branch socket of a synthetic resin pipe to improve the watertightness of the socket.

In general, the water and sewage pipes are connected to the joints of numerous pipes, and the watertightness and the flow of water and sewage should be smooth at each joint area. In particular, in the case of sewage pipes, the leakage of fluid flowing in the pipes causes soil contamination and environmental degradation. Therefore, more perfect water tightness is required.

At this time, the inflow of groundwater due to the incompleteness of the pipe joints increases the processing cost and the surrounding soil flows and is deposited in the pipe, thereby preventing the fluid flow in the pipe and damaging the surrounding ground to damage other installations.

In the conventional pipe structure, branch pipes such as T-shaped pipes or Y-shaped pipes are used at the ends of the pipes, but the T-shaped pipes and the Y-shaped pipes are easily constructed by connecting between the pipes and the pipes. Since the work of connecting the branch pipe to the threaded part of the pipe must be done manually, the workability is degraded and the flow of the fluid may leak inside the joint due to internal pressure or corrosion due to prolonged use. have.

In addition, in order to connect the T pipe or Y pipe to the end of the pipe, it is necessary to separate the combined pipes, combine the T pipes, and then combine the new pipes. This has the disadvantage of being restricted by places.

On the other hand, in the case of branching the branch pipe directly on the pipe constituting the pipe, in order to connect the branch pipe on the pipe, the branch pipe must be firmly coupled without interfering with the water flow due to watertightness and protrusions. The connection conditions are much worse than the construction of T- or Y-tubes and the watertightness of the joints becomes incomplete.

In addition, the conventional branch pipe connecting structure attaches the lower end of the socket for connecting the branch pipe on the through hole formed on the pipe pipe around the through hole, and then connects the branch pipe to the upper end of the socket and uses the socket in the pipe pipe through hole. There are two ways to use the structure of inserting and attaching the branch pipe directly.

However, in both of the above methods, the lower end of the branch pipe does not protrude into the piping pipe. However, when the branch pipe socket is separated by earth pressure or external impact after installation, it is necessary to dig the soil embedded up to the bottom of the pipe pipe. In addition, in the case of pipes with large diameters, even if the joints are fixed with wires, the watertightness is still significantly reduced.

In order to solve such a problem, a structure for firmly connecting a joint socket to a side through hole of a plumbing pipe is disclosed in Korean Utility Model Registration No. 159689 (Registration Date 1999.08.02). Looking briefly as follows.

As shown in Fig. 1, the conventional branch pipe fitting socket is divided into an inner washer (3), which is bisected by dividing the inner washer larger than the inlet hole into the inlet hole in the side inlet hole (10) of the main pipe (1). Packings 7 and 8 are respectively attached to the upper surface of the inner washer wing piece 31 and the inner side of the inner washer 3 which is bisected, and the packing 9 is attached to the inner surface 24 of the protruding portion of the branch pipe socket 2. The inner side washer (3) and the branch pipe socket (2) in close contact with the pipe outer surface (11) in which the wing piece (31) spans the inner surface of the pipe inlet (10) with a plurality of bolts (4). When the nut or the female screw portion 5 of the washer is tightened, the packing 7 of the upper surface of the inner washer wing piece 31 is pressed against the inner surface 12 of the periphery of the pipe inlet hole, and the packing ( 8) and the outer surface 34 or the inner surface 35 of the vertical tube protrusion 36 of the inner washer is attached to the inner surface of the protrusion 24 formed on the lower surface of the branch pipe socket 2 or the inner surface of the protrusion frame 22. The structure is in close contact with the packing 9 and is made watertight by the packings 7, 8 and 9.

The conventional branch pipe socket attachment device having such a structure has a structure in which the inner washer 3 inserted through the inlet hole 10 of the pipe 1 is bisected and pulls the tensile wire 6 connected to both sides of the pipe ( 1) The outer circumferential surface of the washer (3) on the inner circumferential surface in close contact, but the inner washer (3) is inevitably separated in order to be drawn through the inlet hole 10, so the inner circumference of the main pipe ( Even if 3) is tightly coupled, there is a disadvantage that perfect watertightness is difficult.

In addition, as another conventional socket structure, "Application Branch Attachment Socket Attachment Device" of Korea Utility Model Registration No. 142612 (Registration Date 1999. 01. 15) is an outlet hole of the pipe 51, as shown in FIG. Insert the split washer 53 into the outlet hole 61 so as to be caught on the inner side of the outlet hole 61, and the branch socket 52 and the lower side 62 face the packing 51 with the packing 57 facing the outer side of the pipe 51. Inserting the bolt 54 into the bolt hole 66 formed in the 65 and tightening it with the tightening part 55 of the split washer 53 to attach the branch socket 52 to the pipe 51, the inner surface of the branch socket. The protrusion inner surface 64 and the protrusion cover 63 are formed on the protrusion 65 so as to cover the threads 55 of the nut 55 and the bolt 54 which are tightening parts of the split washer 53 with the protrusion cover 63. Structure.

In the conventional branch pipe joint socket structure of the above structure, since the wing piece 70 of the split washer 53 inserted into the outlet hole 61 of the pipe 51 extends only on both sides of the washer, the pipe 51 is formed. When the inner circumferential surface of the coupling is fixed to the inside of the main pipe 51 only by the wing piece 70 extended to prevent the complete sealing by the split washer 53 and the external discharge of the fluid through both sides of the wing piece 70 Problems that can only occur are pointed out.

Japanese Patent Laid-Open No. 7-332567 also discloses a branch pipe connection structure, but since its components are many and complicated to combine, not only the work efficiency is reduced at the work site but also the manufacturing cost increases due to the increase in the number of parts. There are only disadvantages.

Therefore, the present invention has been devised to solve all the disadvantages and problems raised in the conventional branch pipe coupling structure, extending from the lower periphery of the cylindrical branch binding pipe and the branch binding pipe with a male screw portion on the outer peripheral surface is formed on the upper surface A soft adhesive rubber plate is bonded and a socket made of socket wings folded up and down along a bent groove provided on both sides is inserted through a through hole formed on the side of the straight pipe, and branches to both sides of the socket blades in contact with the inner circumferential surface of the straight pipe.
