Description

Drainage device for layered piping {Drainage Device for On-Floor Piping}

The present invention relates to a drainage pipe system for layered pipes for collecting and discharging sewage discharged from a basin and a bathtub and sewage discharged from a basin and a bath tub, and particularly, a drainage pipe body embedded in a concrete floor. The upper frame is formed in a plate shape so as to have a diameter larger than the outer diameter of the main body of the drain pipe system, excluding the installation adjusting means such as a slider, a track groove main body, and the like, which is usually provided between the upper frames installed thereon. The present invention relates to a drainage pipe system for a layered pipe that increases the stability of the drainage pipe device by lowering the height of the device while simplifying the structure of the drainage pipe device by allowing it to flow therethrough.

In general, the drainage system for the layered piping of the basin tub room in which the sink and the tub are installed is discharged by collecting the sewage and the bottom sewage used in the sink and the tub and connected to the sink and the tub by a sewer pipe. It includes a drain pipe device.

As an example of such a drain pipe device, the present applicant has already filed a patent application (No. 2007-068324) on July 6, 2007, the drain pipe device for a layered pipe, as shown in Figure 1, when the bath room floor construction A drain pipe body 110 having an upper portion open and having at least one water collecting pipe fastening portion 111 and one drain pipe fastening portion 112 formed at a side thereof; A track groove body 120 inserted into and fixed to an upper portion of the drain pipe device 110; A slider 130 inserted into the track groove 121 of the track groove body 120 and movable in all directions; An upper frame (160) including an outer frame (140) fastened to the outer frame coupling portion (131) of the slider (130) and an inner frame (150) installed inside the outer frame (140); And it is caught by the inner frame 150 of the upper frame 160, the inside includes a odor backflow prevention device 170 consisting of an outer cylinder 171, the inner cylinder 172 and the tubular body 173.

However, since the drain pipe device as described above has a track groove body 120 and a slider 130 for adjusting the eccentricity of the upper frame between the drain pipe device main body and the upper frame, the overall height of the drain pipe device was high.

Therefore, the layered drainage device has to increase the overall height of the washbasin because the thickness of the finishing material should be thickened when buried in the floor of the conventional standardized washbasin, the construction cost is high, and the door of the washbasin bath There was a problem of opening and closing and there was a problem that the overall design change is necessary.

In order to solve the above problems, the present invention simplifies the structure of the drain pipe device by eliminating the installation adjusting means of the conventional slider, track groove body, etc. provided between the drain pipe device body and the upper frame, and instead improve the configuration of the upper frame. However, by reducing the height so that it can be sufficiently buried in the height of the standard finish of the wash tub, the purpose is to be able to install in the conventional wash tub without the need for design changes for the floor piping.

In addition, it is another object to reduce the additional cost of finishing work by constructing the standardized without increasing the height of the finishing material of the toilet tub.

In addition, it is another object of the present invention to reduce the manufacturing cost by reducing the number of components constituting the layered drainage pipe device for the layered pipe compared to the conventional layered pipe drainage device.

In addition, the present invention provides an upper frame height adjusting means that can adjust the height between the drain pipe device main body and the upper frame when the thickness of the finishing material is thicker than the height of the drain pipe device for the layered pipe to increase the height between the drain pipe device main body and the upper frame. Another aim is to adjust it to fit the height of the finish.

In addition, the present invention is further connected to the water collecting pipe fastening portion formed in the main body of the drain pipe device to further remove the sewage trap without the need to install a P trap or U trap, etc. Another object is to prevent backflow of odor.

In addition, it is another object of the present invention to provide a drain pipe device main body capable of fastening a large capacity drain trap by forming a bottom of the water collecting pipe fastening part side of the drain pipe device main body according to the present invention stepped deep in a semicircle shape.

In addition, the cross section of the outer cylinder, inner cylinder and the strainer of the odor backflow fastener fastened to the upper plate to solve the shortening of the flow distance of the odor backflow fastener fastened to the upper frame when the drainage trap is fastened to the main body of the drain pipe device according to the present invention Another object is to form a semi-circular shape so that the flat portion is located toward the drain trap to secure the separation distance of the odor reflux prevention port.

In order to achieve the above object, the present invention is installed on the concrete floor for the basin bath basin and the upper open cylindrical drain pipe body having a water collecting pipe fastening portion and a drain pipe fastening portion in the side portion; It is mounted on the upper portion of the drain pipe device body and flows, and has a diameter larger than the outer diameter of the drain pipe device body and the upper frame plate fastening portion for fastening the upper frame plate on the upper surface, and the plate-shaped reverse flow prevention port fastening portion in the center It provides a drainage pipe device for a layered pipe comprising an upper frame.

As described above, the present invention simplifies the structure of the drain pipe device while improving the configuration of the upper pipe by eliminating the installation adjusting means of the conventional slider, the track groove body, etc. provided between the drain pipe device main body and the upper frame. By reducing the height of the finished material of the standardized bath tub can be sufficiently buried can be installed in a conventional bath tub without the need for design changes for the floor piping.

In addition, it is possible to reduce the additional finishing cost required by the construction as it is standardized without increasing the height of the finishing material of the toilet tub.

In addition, the layered pipe drain pipe device of the present invention can reduce the manufacturing cost by reducing the number of components constituting as compared to the conventional layered pipe pipe.

In addition, the present invention provides an upper frame height adjusting means that can adjust the height between the drain pipe device main body and the upper frame when the thickness of the finishing material is thicker than the height of the drain pipe device for the layered pipe to increase the height between the drain pipe device main body and the upper frame. I can regulate it.

In addition, by further tightening a removable drain trap formed in the water collecting pipe fastening portion formed in the main body of the drain pipe device, it is not necessary to install a P trap or a U trap on the drain pipe for discharging the sewage of the basin or the tub connected to the water collecting hole. Reverse flow can be prevented.

In addition, the bottom of the water collecting pipe side of the drain pipe device main body is formed deep in a semicircular step to fasten the large capacity drain trap can smoothly discharge the sewage of the wash basin or bathtub.

In addition, when the drain trap is fastened to the main body of the drain pipe device, a cross section is formed in a semicircular shape so that one side thereof becomes a plane, and the flat portion is positioned toward the drain trap so that the flat portion is spaced apart toward the drain trap. By securing the distance, the flow distance of the top plate can be increased.
