Description

Drain-Pipe Joint}

The present invention relates to a drain connection pipe, and more particularly, to a drain connection pipe in which the connection of the drain pipe is easy and water leakage does not occur to the fastening part.

Usually, for the drainage of the apartment veranda, the upper and lower floors are connected with a drain pipe, and each drain pipe is piped through a connector. In construction, after fixing the connector on the formwork, concrete is poured to form the floor, and decorative materials such as tiles are attached on it to finish. After that, when the drain pipe is connected up and down at the connector, the domestic sewage coming down from each floor joins through the connector and is discharged through the underground sewer pipe.

Although these apartment verandas are being constructed with standardized dimensions, their height may vary depending on the change of times or the choice of floor decoration materials. Accordingly, since the dimensions of the connector must be provided in various ways, it causes inconvenience and cost increase to the manufacturer of the connector or the contractors who use it.

Moreover, in recent years, as the number of cases of applying a flat structure suitable to the characteristics of each household as a part of differentiation and respect for individuality in apartment houses, etc. has increased, the construction location of the wall is somewhat different for each floor. The location of the drain pipe is also not arranged on the same vertical line as the lower floor, and there is a case where a slight separation distance is maintained, and for this, a separate auxiliary connecting pipe is used.

As shown in the Republic of Korea Utility Model Registration No. 20-0207070, in the prior art performing the above function, in a connector for connecting an upper drain pipe and a lower floor drain pipe of a multi-story building such as an apartment: a fixing member having a stepped portion on the inner surface; a fixing body coupled to the upper portion of the fixing member through a locking protrusion, integrally forming a flange on the upper end of the outer surface, and accommodating the upper end of the lower drain pipe at the lower end; an adjustment body coupled to the upper portion of the fixed body using a spiral, and having a lower partition wall at the lower end of the inner surface and a flange at the upper end of the outer surface; a merging pipe inserted and mounted on the upper portion of the control body and having a blocking wall on an inner surface and a drain through hole on the upper end of the outer surface; and an assembly pipe coupled to the upper part of the confluence pipe using a spiral and accommodating the lower end of the upper drain pipe at the upper end.

However, the prior art configuration has the following problems.

In order to connect the drain pipe, the assembly pipe is lowered to enter the merging pipe, and then the assembly pipe is raised according to the length of the drain pipe to finish, so the work process is complicated. There is a problem of leakage.

Republic of Korea Registered Utility Model No. 20-0207070. (December 15, 2000)

An object of the present invention has been devised to solve the problems described above in the prior art, and it is an object of the present invention to prevent leakage of water to a fastening part while making it easy to connect a drain pipe.

Figure 1 is an exploded perspective view showing the drain connection pipe of the present invention, Figure 2 is a combined perspective view showing the drain connection pipe of the present invention, Figure 3 is an exploded perspective view showing the drain connection pipe of the present invention, Figures 4 and 5 are the inventors It is a cross-sectional view showing a drain connection pipe, and FIG. 6 is an enlarged cross-sectional view of part A of FIG. 4 .

First, as shown in FIGS. 1 to 3 , looking at the configuration of the drain connection pipe 100 according to the present invention, the buried drain pipe 10 is connected to one side of the connection pipe 110 installed inside the floor on which concrete C is poured, and the top and bottom are granular. In the drain connection pipe 100 in which the drain pipe 20 is installed, it consists of a coupling pipe 120, a control pipe 130, and a fire resistant filler 140.

Here, the connecting pipe 110 is provided with a vertical pipe 111 through which the inside is formed, and a horizontal pipe 115 communicating with the vertical pipe 111 is formed on the side of the vertical pipe 111. The buried drain pipe 10 is fitted to the horizontal pipe 115 .

In addition, the coupling pipe 120 is coupled to the upper portion of the connection pipe 110 .

In particular, a plurality of coupling protrusions 123 are formed on the outer periphery of the coupling pipe 120, and a locking groove 113 into which the coupling protrusions 123 are fitted is formed on the inner periphery of the coupling pipe 110 to prevent rotation.

In addition, a control pipe 130 that is fastened to enter the coupling pipe 120 and rises according to the height of the standing drain pipe 20 is provided. Here, the control tube 130 has a male screw 131 fastened to the female screw 121 formed inside the coupling tube 120 is formed on the outer periphery.

At this time, as shown in FIG. 6 , the male screw 131 of the coupling pipe 120 has a slope θ that is narrowed from the bottom to the top.

That is, as shown in FIG. 4, after positioning the rising drain pipe 20 in a state in which the control pipe 130 is inserted inside the connection pipe 110, as shown in FIG. fit the length

Here, a locking jaw 137 is formed on the inside of the control tube 130 to support the upright drain tube 20 . In addition, the packing 160 surrounding the outer circumferential surface of the rising drain pipe 20 is inserted into the upper part of the adjusting pipe 130, and the upper cap 150 having the rotating protrusion 151 formed on the outer periphery is screwed to the upper part of the adjusting pipe 130 to press the packing 160.

In addition, the guide tube 133 is extended to the lower side of the control tube 130 narrowly downward, and the guide members 135 inclined on the inner periphery of the guide tube 133 are formed at equal intervals, so that the wastewater can be discharged quickly.

As a result, in the drain connection pipe 100 according to an embodiment of the present invention, the male screw 131 is fastened to the female screw 121 formed inside the coupling pipe 120 so that the connection of the upright drain pipe 20 is easy and no leakage occurs to the fastening part. 130 It is formed on the outer periphery, and the male screw 131 is inclined to be narrower from the lower part to the upper part, so that the assembly time is shortened and the sealing force and fastening force are improved.

On the other hand, the fire resistant filler 140 is fitted to the lower portion of the connection pipe 110 . The fire resistant filler 140 has a three-layer structure comprising a tubular fire resistant expansion layer made of a thermally expansible fire resistant resin composition, an outer coating layer covering the outside of the fire resistant expansion layer, and an inner coating layer covering the inside of the fire resistant expansion layer. As a multilayer fire resistant piping material of The coating layer is a polyvinyl chloride-based resin composition containing no thermally expansible refractory material.

Since the fire-resistant filler 140 has a certain strength, it is possible to fit into the lower part of the connection pipe 110 . In addition, the fire resistant filler 140 and the auxiliary member 170 are inserted in the lower portion of the connection pipe 110 . At this time, a plurality of pressing protrusions 173 are formed on the outer periphery of the auxiliary member 170 to press the inner periphery of the fire resistant filler 140 . In particular, the upper part of the upright drain pipe 20 is fitted by forming an insertion groove 171 that is opened downwardly in the auxiliary member 170 .
