Looking at the drain pipe connection configuration of an assembly building, a sleeve is embedded in the ceiling slab and floor slab of each floor, and a long drain pipe is connected between the ceiling and floor sleeves. Here, the drain pipe is called a standing drain pipe because it is installed vertically (upright), and this name will be used in this specification as well.

On the other hand, when connecting between the ceiling and the floor sleeve by a rising drain pipe, the rising drain pipe may be directly connected without a separate connection means, or it may be connected via a YT pipe (aka, sextia).

1 shows a conventional connection structure in which a rising drain pipe is connected via a YT pipe.

The lower part of the standing drain pipe (3) is fitted to the lower sleeve (2) embedded in the floor slab (1).

Next, the upper part of the connection pipe 10 is fitted and coupled to the upper sleeve 5 embedded in the ceiling slab 4 .

Next, in a state where the upper connector 21 of the YT pipe 20 is fitted in the lower part of the connector 10, the YT pipe by the gap between the lower connector 22 of the YT pipe 20 and the upper end of the rising drain pipe 3 (20) is pulled down and the lower connector (22) is fitted to the upper end of the upright drain pipe (3).

Next, the lower ring clamp (22a), which has been fastened to the lower connector (22) of the YT tube (20), is tightened by rotating it. Then, the gap between the lower connection part 22 and the rising drain pipe 3 is sealed by the O-ring 30 .

Finally, as in the right side view of FIG. 1, by applying an adhesive (b) between the upper connector 21 of the connecting pipe 10 and the YT pipe 20, instead of sealing, the YT pipe 20 It also prevents sagging.

In such a conventional upright drain pipe connection device, the YT pipe 20 may sag due to its own weight over time, and furthermore, when the pipe pipe (not shown) is connected to the side connector 23 of the YT pipe 20, the weight The sagging phenomenon of the YT tube 20 may be intensified by being weighted.

In order to prevent this, the side connector 23 is sometimes supported on the ceiling by using a U clip, but in this case, there is a problem in that work and parts are added.

In addition, the operation of applying the adhesive (b) between the connecting pipe 10 and the upper connector 21 of the YT pipe 20 has a problem in that the working environment is not eco-friendly as well as an additional problem in the number of work hours, and the adhesive state is Because there are many cases of poor quality, it is also the main cause of leakage and odor leakage.

In addition, the O-ring 30 that is pressed between the upper outer circumferential surface of the rising drain pipe 3 and the inner circumferential surface of the lower connector 22 by tightening the lower ring clamp 22a while being inserted into the outer circumferential surface of the rising drain pipe 3 is pressed In the process, the shape may be distorted or it may not be seated properly, which may cause sealing problems, which may lead to odor and backflow water leakage.

Referring to the above drawing, the rising drain pipe connecting device 100 according to the present invention is for connecting the upper sleeve 5 embedded in the ceiling slab 4 and the upper part of the rising drain 3, and the external connecting pipe 110 ), an internal connection pipe 120 , a tightening ring 130 , and upper and lower O-rings 141 and 142 .

The external connection tube 110 has a circular tube shape in which the upper and lower portions are open.

The external connection pipe 110 has a stepped O-ring seating part 111 formed on the inner peripheral surfaces of the upper and lower sides, so that the upper and lower O-rings 141 and 142 may be seated, respectively.

In addition, a screw portion 112 to which the ring clamp 150 is screwed may be formed on the outer peripheral surface of the lower end of the external connection pipe 110 .

In addition, a locking protrusion 113 may be formed at a predetermined position on the inner circumferential surface of the external connection pipe 110 . Accordingly, an upper intubation portion 114 through which the internal connection tube 120 is intubated is provided on the upper side with respect to the stopping protrusion 113 , and a lower intubation portion in which the upper part of the standing drain tube 3 is intubated on the lower side. (115) is provided.

The inner connecting tube 120 has a circular tube shape with the upper and lower portions open.

When the lower part of the internal connector 120 is slidably inserted into the upper cannulation part 114 of the external connector 110 , it is caught on the upper side of the hook 113 of the external connector 110 . up to can be inserted.

Here, the length of the internal connection tube 120 is configured to be longer than the length of the upper intubation part 114 of the external connection tube 110 . Therefore, even if the inner connection tube 120 is inserted as much as possible until it is caught on the locking jaw 113, the upper side is exposed to the outside.

In addition, a male tab 121 may be formed in a portion of an outer peripheral surface of the internal connection pipe 120 . Here, the male tab 121 may be formed on the exposed outer circumferential surface based on the time when it is completely inserted until it is caught on the locking jaw 113 of the upper intubation part 114 .

On the other hand, the upper end of the internal connection tube 120 may be directly connected to the upper sleeve 5 or may be coupled to the lower portion of the YT tube 11 fitted in the upper sleeve.

Here, the upper end of the inner connection tube 120 fitted to the upper sleeve 5 or the YT tube 11 may be in a form in which the inner and outer diameters are expanded, as in FIG. 3 , as another example, in FIG. As in the right side view of 3 and FIG. 5, the inner and outer diameters may be formed the same as other parts (for reference, FIG. 5 enlarges part B of FIG. 4C, but replaces the straight upper end of the internal connection pipe. applied drawing).

In the former case, as in Figs. 4a to 4c, when the internal connection pipe 120 is inserted into the lower part of the YT pipe 11, there is no protruding part in the inner diameter part, so it is advantageous to reduce the drainage noise, and in the latter case is a structure that is relatively unfavorable in terms of drainage noise compared to the former case because a step (part A in the drawing) is formed between the YT tube 11 and the internal connection tube 120, but is structurally simple compared to the former type Since it has the advantage of being easy to manufacture, you can cook and use one of the two according to the situation.

On the other hand, the inner diameter of the inner connection pipe 120, the stopping protrusion 113, and the standing drain pipe 3 may be formed to be the same. The inner diameters of the internal connection pipe 120, the locking protrusion 113, and the standing drain pipe 3 are substantially equivalent to the drain passage. The fact that the inner diameter of the drain passages is the same means that there is no protruding part, so when the drained water is discharged through this, it can be discharged without resistance to discharge, so that almost no exhaust noise is generated.

The tightening ring 130 serves to press the upper O-ring 141 by a lowering operation and also to push up the inner connection tube 120 to be closely coupled to the upper sleeve 5 or the YT tube 11 .

The tightening ring 130 has a circular tube shape with an open upper and lower portions, and the length may be shorter than that of the internal connection tube 120 .

The tightening ring 130 may have a female tab 131 formed in a portion of its inner circumferential surface to engage the male tab 121 of the internal connection pipe 120 . Therefore, when the tightening ring 130 is rotated, the upper O-ring 141 is pressed by the lower end while descending along the internal connection pipe 120 , and if the rotation operation is continued after that, the internal connection pipe 120 is relatively ) so that the upper side is closely coupled to the upper sleeve 5 or the YT tube 11 by raising it.

The upper O-ring 141 is seated and installed on the upper O-ring seating portion 11 of the external connection pipe 110 , while being pressed by the tightening ring 130 , the internal connection pipe 120 and the external connection pipe 110 ) It serves to seal the gap between

The lower O-ring 142 is seated and installed on the lower O-ring seating portion 11 of the external connection pipe 110, while being pressed by the ring clamp 150, between the upright drain pipe 3 and the external connection pipe 110. It serves to seal the gap.

Here, the ring clamp 150 includes a fastening part 151 screw-fastened to the screw part 112 provided at the lower end of the outer circumferential surface of the external connection pipe 110, and provided inside the fastening part, to secure the lower O-ring 142. It may be composed of a pressing part 152 that presses the O-ring seating part 111 .

Hereinafter, a method for constructing a rising drain pipe using the above-described rising drain pipe connecting device will be described.

First, the upper part of the standing drain pipe 3 is intubated into the lower intubation part 115 of the external connection pipe 110 . At this time, the standing drain pipe 3 is intubated until it is caught on the locking jaw 113 .

Next, the ring clamp 150, which has been fastened to the lower part of the external connection pipe 110, is tightened by rotating it. Accordingly, the pressing part 152 of the ring clamp 150 presses the lower O-ring 142 to seal the gap between the upright drain pipe 3 and the external connection pipe 110 .

Next, in a state in which the female tab 131 of the tightening ring 130 is engaged with the male tab 121 of the internal connection pipe 120 , the lower part of the internal connection pipe 120 is connected to the upper part of the external connection pipe 110 . is intubated to the upper intubation part 114 . At this time, the internal connection tube 120 is intubated until it is caught on the locking jaw 113 .

Next, the lower part of the standing drain pipe (3) is coupled to the lower sleeve (2) embedded in the floor slab (1).

Next, after inserting the inner connecting pipe 120 toward the upper sleeve 5 or the YT pipe 20 embedded in the ceiling slab 4 and inserting it, the tightening ring 130 is internally connected by rotation operation. It descends along the pipe 120 to press the upper O-ring 141 of the external connection pipe 110 , and at the same time move the internal connection pipe 120 relatively upward so as to be in close contact with the ceiling sleeve 4 . do.

Here, when the YT tube 20 is first inserted into the upper sleeve 5, the sealing rubber R of the 'L' shape surrounding the upper end of the YT tube 20 is covered by fitting, and the other For example, when connecting the internal connection pipe 12 directly to the upper sleeve 5, it is preferable to fit in a state in which a sealing part of a shape surrounding the upper end of the internal connection pipe is covered. Therefore, it is possible to strengthen the airtightness and watertightness in each fitting portion.

Accordingly, the rising drain pipe connecting device according to the present invention can prevent the sagging phenomenon as the inner connecting pipe is brought into close contact with the upper sleeve by the tightening ring, and the inner diameter of the inner connecting pipe, the engaging jaw and the standing drain pipe forming the drain passage Since the assembly structure is identically formed and there is no protruding part, it is possible to discharge low noise without resistance to discharge when discharged water is discharged. By doing so, it is possible to solve the problem of leakage of odors or countercurrent. In addition, since the present invention does not require a process for applying an adhesive, the working environment is pleasant and the number of working hours can be reduced.

Although the above-described embodiment has been described with respect to a preferred embodiment of the present invention, the present invention is not limited thereto, and it is specified that it can be changed and implemented in various forms without departing from the technical spirit of the present invention.
