Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings.

Referring to Figures 2 and 3 showing the drainage pipe connection device according to the present invention, this is the main drainage tank 100 and the sub-drainage tank 200 is embedded so that the upper and lower surfaces are exposed to the concrete 300, such as the veranda It has a structure to drain the falling rainwater or wastewater and the wastewater in each layer together.

The main drainage tank 100 is formed in a hollow having an inlet and an outlet at the top and bottom thereof, and a connection hole 103 connected to the hollow is formed at a side thereof. The lower outlet side edge is coupled with a large diameter drain pipe 110 of the lower layer, and a lower annular rib 104 connected with the small diameter drain pipe 111 of the lower layer and a small diameter drain pipe 121 of the upper layer have a predetermined first connection means. The upper annular ribs 105 connected to each other are connected to the plurality of connecting ribs 106.

A hollow hopper 150 is rotatably coupled to the main drainage tank 100, and a plurality of inclinations for guiding rainwater or wastewater drained from the upper large diameter drainage pipe 120 to form a vortex on an inner circumferential surface of the hopper 150. The wing 152 is formed, and the hopper 150 and the large diameter drain pipe 120 of the upper layer are connected by a predetermined second connecting means.

The sub-drain 200 is formed with a discharge hole 201 connected to the connection hole 103 at one side thereof, and an inlet 202 through which wastewater from each layer is introduced.

The first connecting means is one end is coupled to the upper annular rib 105, the inclined compensating tube 130 is formed with a stretchable wrinkle portion 131 at the center thereof, and one end at the other end of the inclined compensating tube 130 It has a structure that is provided with a first up and down adjustment pipe 140 is joined and the other end of the small diameter drain pipe 121 is connected to the other end. Here, the female screw is formed on the inner circumferential surface of one end of the inclined compensating tube 130, and the male screw is formed on the outer circumferential surface of the one end of the first vertical adjustment tube 140. Such first connecting means can reduce the deviation by adjusting its height with the first up and down adjustment pipe 140 even if there is a deviation in the length of the small diameter drain pipe 121 of the upper layer, and left and right deviation occurs in the drain hole position between the upper and lower layers. Even if the bending of the wrinkles 131 can be overcome the deviation.

The second connecting means has an eccentric hole formed in the upper end of the hopper 150, the left and right adjusting member 180 is rotatably coupled to the eccentric hole, and one end thereof is engaged with the left and right adjusting member 180 and The other end has a structure that is provided with a second vertical adjustment pipe 190 is connected to the large diameter drain pipe 120 of the upper layer.

The second connecting means can overcome the length difference by the vertical adjustment of the second vertical adjustment member 190, even if the length of the large diameter drain pipe 120 of the upper layer is short, and also the deviation in the installation position of the drain hole between the upper and lower layers When the occurrence of the deviation can be overcome by adjusting the left and right adjusting member 180 and the hopper 150.

In addition, a first through hole 401 through which the upper drain pipe 120 and 121 penetrates is formed at one side of the main drain tank 100 and the sub drain tank 200, and the inlet 202 is located at the other side. A finishing member 400 having a second through hole 402 communicating with is provided. Here, the shielding portion 403 is formed at the edge of the first through hole 401 of the closing member 400 to shield the connection portion of the second up and down adjustment pipe 190 and the large diameter drainage pipe 120 from being exposed to the outside. It is.

On the other hand, the upper portion of the main drain tank 100 and the sub-drain tank 200 may be installed to be further seated auxiliary ring members (510, 511, 500, 501) of a predetermined width, respectively. In this case, an error due to a difference between the height of the upper and lower layers and the length of the upper drain pipe 120 may be overcome.

Reference numeral 600 is a filter net formed with a plurality of holes coupled to the second through hole 402 of the closure member 400.

On the other hand, the main drainage tank 100 has a fixed plate 700 whose inner diameter is spaced apart from the main drainage tank 100 and whose outer diameter is fixed to the outlet side edge of the main drainage tank 100 as a fixed bolt 710. It is fixed, the outer peripheral surface of the lower large diameter drain pipe 110 is formed an annular support rib (110a) rotatably coupled between the fixed plate 700 and the main drain tank (100).

The lower large diameter drain pipe 110 and the lower small diameter drain pipe 111 are integrally formed as shown. In addition, the fixing plate 700 is divided because it is impossible to combine with the drain pipe 110, 111 as shown in Figure 3,

In addition, in the case where the main drainage tank 100a drains only the domestic wastewater, as shown in FIG. 4, the drainage pipe 110b does not require the lower small drainage pipe 111 as described above, and in this case, the fixed plate 700a. ) Is structurally coupled to the drain pipe 110b and thus may be formed in an annular shape.

In addition, as shown in Figure 3, the end of the lower large diameter drain pipe 110 is coupled to the connection pipe 800 for discharging the domestic wastewater to the septic tank (not shown), the connection pipe 800 is a packing body 810 and the lower large diameter drain pipe 110 is connected by a tightening knob 820 coupled to the screw portion (110f) formed.

On the other hand, when the main drain tank (100) (100a) is embedded in the bottom concrete 300, the fixed bolts (710) (710a) is embedded in the state coupled to the main drain tank (100) (100a) and the concrete is After curing, it is preferable to remove each fixing bolt (710) (710a). In this case, the concrete is prevented from entering the coupling hole of the fixing bolts 710 and 710a when the concrete is poured, and then enters the coupling hole of the fixing bolts 710 and 710a when the fixing plate 700 is fixed. Eliminate the hassle of removing the hardened concrete.

In such a device, since the drain pipe can be rotated 360 degrees after assembling the drain pipes 110 and 111, the device can be connected regardless of the position of the connection pipe 800. Also, no drain pipe support such as a hanger is required.

On the other hand, rainwater and wastewater drained from the rooftop through the small diameter drain pipe (121, 111) is immediately drained through the sewer (not shown), the wastewater flowing out through the sub-drainage tank 200 is the main drainage tank (100) It will be drained through the large diameter drain pipe 110 of the lower layer via. At this time, wastewater of each layer through the large diameter drainage pipes 110 and 120 is drained through a septic tank (not shown).

First, since the drain pipe 110 is rotatably coupled to the main drain tank 100 by the fixing plate 700, the hanger is not required unlike the conventional apparatus as described above.

Second, even when the drain pipe 100 is coupled to the 360 degree rotation is possible, even if the connection pipe 800 is located on the left or right is possible to combine.

Third, since the drain pipe 110 and the connecting pipe 800 are coupled by the tightening knob 820, the coupling and separation is simplified.
