Description

Double pipe type floor drainage apparatus for floor and buried piping {Dual pipe type floor drainage apparatus}

The present design relates to a drainage system used for the construction of floor pipes in bathrooms of apartments, etc., and more specifically, a double pipe connector is installed in the side connection pipe of the sump installed on the floor slab, and at the same time, the double pipe connector is installed on the side connection pipe. Double piping type drainage for single-layered or buried piping so that maintenance can be quickly and easily performed without removing the tile layer and the mortar layer when maintenance is required as double piping can be arranged into the connecting piping that is connected and arranged in the mortar layer. It relates to the device.

Among multi-family houses, apartments are the most representative form of housing in the modern society, and although they have the advantage of being able to live in many people despite their small area, they also have a big disadvantage of generating inter-floor noise between floors and floors.

There are various causes of inter-floor noise in apartments, but among them, bathroom noise is a problem related to the building structure, not just the tenant.

As the drainage pipes connected to the bathtub, sink and toilet installed in the upper bathroom penetrate the floor slab and are installed on the ceiling of the lower floor, when using the bathroom on the upper floor, the sound of water flowing through the pipe is transmitted to the lower floor, causing inter-floor noise. Such a piping structure also has a problem of damaging others because it is necessary to work on the lower floor during maintenance.

In order to solve this problem, various drainage pipes for collecting and discharging the sewage used in the sink and bathtub of the bathroom and the sewage from the bathroom floor are installed on the mortar layer on the floor slab of the corresponding floor, not on the lower ceiling, but on the floor for floor or buried plumbing. Drainage systems have been developed.

In such a floor drainage system for layered or buried piping, it is troublesome to perforate the floor slab as various drainage piping materials for drainage penetrate the floor slab and are not installed on the ceiling of the lower floor, but are arranged on the floor slab and connected to a vertical hollow pipe. There is an advantage in that there is no noise between floors due to use of the bathroom and can be reduced.

As an example of such a floor drainage device for floor or buried piping, Korean Patent Publication No. 10-2009-0124896 (published on Dec. 03, 2009) is installed on the concrete floor for the foundation floor of the wash basin room, and the water collecting pipe fastening part is located on a part of the side. And an upper open cylindrical drain pipe device main body having a drain pipe fastening part, and a plate-shaped upper base that is mounted on the top of the drain pipe device and flows, has a diameter larger than the outer diameter of the drain pipe device body, and has an odor backflow prevention port fastening part formed in the center. Including, wherein the upper base plate has a triangular cross-section for fixing the upper base plate and is divided by a band-shaped protrusion equal to the area of the upper base plate, and formed in the center of the upper base plate fastening part Disclosed is a drainage pipe device for a layered or buried pipe, characterized in that it consists of an inner frame fastening part.

In addition, in Korean Utility Model Publication No. 20-2017-0002282 (published on 27 June 2017), it is installed on the reinforced concrete for the foundation floor of the bathroom and is formed in the shape of a case with an open top surface, and a first drainage connector is provided on one side. A floor drain body portion extending away from the reinforced concrete for the foundation floor, an external member accommodated in the bottom drain body portion and formed in the shape of a case with an open top surface, and seated on the top of the bottom drain body portion and inside An upper frame having a first stepped jaw on the lower side of the surface and a second stepped jaw formed on the upper side of the inner surface, and the external member having a vertically penetrating portion and an upper end seated and supported on the first end of the upper frame. An internal member extending inward and a lower end spaced apart from the bottom surface of the external member, a drain cover seated on a second step of the upper frame and formed through a plurality of drain holes, and a first drainage of the bottom drain body portion at one side For layered or buried piping including an L-shaped or T-shaped drainage part in which a second drainage connector to which a connector is inserted and connected is extended in a state spaced apart from the reinforced concrete for the foundation floor, and a third drainage connector is extended on the other side. A floor drainage device is disclosed.

Doedoe arranged, preferably located below the center of the connector body (41).

In addition, for watertight connection of the double pipe connector 40 to the side connector 11 of the water collecting container 10, a ring groove 41a is recessed around the outer circumference of the connector body 41, and the connector body 41 It is preferable that a packing ring 45 made of an elastic material such as rubber, silicone, urethane, etc. that watertightly contacts the inner wall of the side connector 11 of the water collecting tank 10 is coupled to the ring groove 41a of ). At this time, in order to ensure the watertight connection of the double pipe connector 40, it is preferable that, for example, an uneven protrusion of a triangular cross-section is formed along the outer circumferential surface of the packing ring 45.

The double pipe 50 is connected to the double connector 43 of the double pipe connector 40 and is arranged in the connection pipe 30. The double pipe 50 corresponds to an actual drain pipe that allows the sewage in the water collection tank 10 to flow through and drain to the common vertical pipe 9, and one end is connected to the double connector 43 of the double pipe connector 40 And the other end extends into the common vertical pipe (9).

It is preferable that the double pipe 50 is formed of a corrugated pipe that is flexible and capable of extending and contracting in length.

The double piping type floor drainage device 1 for layered and buried piping according to an embodiment of the present invention as described above is a double piping in the side connection pipe 11 of the water collecting canister 10 installed on the floor slab 3 The double pipe connector 40 for the connection of 50 is installed to be watertight, so that it is connected to the side connector 11 of the water collecting tank 10 and arranged in the mortar layer 5 on the floor slab 3 ( 30) It has a structure in which the double pipe 50 can be arranged.

Due to the addition of the double pipe connector 40 and the double pipe 50, the sewage in the water collecting canister 10 does not flow into the connection pipe 30, and the joint through the side connection pipe 11 and the double pipe 50 As it is drained to the vertical pipe 9, when maintenance is required due to blockage, etc., maintenance can be performed quickly and easily without removing the tile layer 5a and the mortar layer 5.

In particular, when maintenance is required, the double pipe connector 40 and the double pipe 50 are easily withdrawn through the inside of the water collecting canister 10 from which the drain trap 20 is removed to solve the clogging problem and then easily re-install it. Maintenance can be made more convenient because it can be replaced with a new double pipe connector 40 and a double pipe 50.

In addition, when the double-pipe type floor drainage device 1 for layered and buried pipes according to an embodiment of the present invention is applied, the sewage in the water collecting tank 10 does not flow into the connection pipe 30 and the side connection pipe 11 and the As the water is drained to the common vertical pipe 9 through the double pipe 50, a water leakage problem due to damage of the connection pipe 30 can be prevented in advance.

Although some embodiments have been exemplarily described above, the fact that the present invention can be embodied in various forms without departing from the spirit and scope thereof is obvious to those of ordinary skill in the art. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and all implementations within the scope of the appended claims and equivalents thereof will be included within the scope of the present invention.
