Drainage Device on Floor Having

The present invention relates to a drainage pipe device for stratified piping, and in particular, a water collecting pipe using a structural change and an elbow of a drainage pipe device body constituting the drainage pipe device without using a separate drainage trap to prevent odor backflow to a bathtub or a basin. While providing a role of the drain trap, it provides a drain pipe device for the layered pipe to enable the installation of the collection pipe in a straight form.

In general, the drain pipe device embedded in the floor of the washbasin chamber can be divided into the drainage pipe device for the sub-floor pipe buried in the foundation concrete (hereinafter referred to as the slab) and the drain pipe device for the floor pipe installed in the upper part of the slab and embedded in the finishing material. have.

As shown in FIG. 1, the drainage pipe device for the lower layer pipe has an outer diameter smaller than the interval of the standardized reinforcing bar when constructing the floor of the tub, and sewage of the wash basin or the tub for collecting the sewage discharged from the sink and the bathtub. A water collecting pipe fastening part 12 for inserting and fastening a water collecting pipe 70 to collect water, and a drain pipe fastening part for collecting and discharging sewage introduced from the water collecting pipe 70 and sewage introduced from the bottom of the wash tub chamber ( A drain pipe body 10 having 11); The slide groove 30 is inserted into the upper portion of the drain pipe device body 10 and fixed to the upper end of the drain pipe device body, and the slider 30 is inserted into the track groove 21 of the track groove body 20 and flows in all directions. ) And an upper base portion 40 coupled to the upper key contention portion of the slider 30 and having an intake backflow prevention insert inserted at the center thereof and movable in all directions by the coupled slider 30, and the upper base 40. Intake backflow prevention device is inserted into the intake backflow prevention device of the intake, the outflow prevention port consisting of the inner and outer cylinders (52, 51) and the inner tube (53), and the upper base plate (60) is fixed to the upper portion of the upper frame )

  The drainage pipe apparatus as described above typically requires a separate P trap beneath the washbasin to prevent backflow of odor coming from the drainage pipe through the basin drainage pipe connected to the collecting pipe. There was a problem that it is difficult to drain the P trap is blocked a lot of damage.

In addition, in order to drain the tub, a separate tub sleeve is embedded in the slab, and then a P trap is connected to the bottom of the tub sleeve, a tub drain pipe is connected, and the P trap is inserted into the tub sleeve. If there is a blockage can be checked using the toilet downstairs there was a problem that management is very cumbersome and not easy to construct.

In addition, since the drain pipe for draining the collected sewage is formed on the ceiling of the lower floor, the noise of the sewage discharged from the upper floor is directly introduced into the lower floor, and the upper and lower floors are blocked by thin PVC membranes such as the drain pipe device and the drain pipe. Because of the shape, the noise generated inside the upper bath tub is transmitted directly to the lower floor, which can infringe on the privacy of the person using the upper bath tub, and it can cause discomfort to the lower floor. There was a problem.

In addition, since the water collecting pipe is buried in the foundation concrete floor, when the water collecting pipe is damaged during the construction of the floor to the lower floor, water leaks into the lower floor as it flows into the lower floor. There was a problem that a lot of repair costs such as the need to remove all the concrete and reconstruction.

In addition, since all the drain pipe devices are buried in concrete except the upper frame, when foreign matters accumulate inside the drain pipe device body and the drainage does not occur smoothly, the drain pipe device is disassembled. You had to put a tool or a tool to remove the foreign object. However, since the diameter of the odor reflux insertion port insertion port is too small, it is difficult for an adult to put his hand, and even when using tongs, there is a problem that it is difficult to remove foreign substances inside the main body of the drain pipe device.

In order to solve the above problems, there is a commercially available drainage pipe device for the layered pipe used in the toilet tub drainage system filed by the applicant.

As shown in FIG. 2, the drainage pipe device for the layered pipe is opened during the construction of the bottom of the wash tub and has at least one water collecting pipe fastening part 501 and one drain pipe fastening part 502 formed on a side thereof. 500); A track groove body 510 inserted into and fixed to an upper portion of the drain pipe device 500; A slider 520 inserted into the track groove 511 of the track groove body 510 and movable in all directions; An outer frame 410 fastened to the upper frame coupling portion 512 of the slider 520, and is installed in the outer frame 410, and includes an outer cylinder 531, an inner cylinder 532, and a tubular body 543.

Therefore, when the installation position of the drainage pipe body is constructed out of the design position, it is necessary to install the upper frame at the right position by moving the intake backflow prevention device in all directions, but it is difficult to install it in the designed position due to the drainage trap that is fastened to the catchment pipe fastener. There was a problem.

In addition, when the drain trap and the intake backflow prevention device are installed in close contact with each other, the sewage of the wash basin or the tub drained through the drainage trap is disturbed by the outer cylinder of the intake backflow prevention device, and foreign matter such as hair accumulates or affects the drainage speed. There was also a problem that it takes a long time to drain the sewage of the wash basin or bathtub.

In addition, there is a problem in that a separate manufacturing cost is required by using a drain trap that is separately manufactured and detached in order to prevent odor backflow into the wash basin or the bathtub, and needs to be detachable when cleaning.

In addition, the collecting pipe fastening portion formed on the side of the drain pipe device is fixed in one direction, so if the collecting pipe fastening portion and the basin or the tub drain are not located in a straight line, the collection pipe should be forcibly bent or various angle elbows should be used. There was also a problem that the construction cost increased and the construction was cumbersome.

In order to solve the above problems, the present invention, the bottom of the drain pipe device constituting the laminar drain pipe device is formed stepped to a constant height, the bottom is formed in the stepped bottom connected to the bottom of the slab to be installed is extended elbow The collection pipe fasteners can be inserted, and by forming a drain pipe fastener for discharging sewage flowed from the upper or collection pipes on either side wall of the side walls facing the bottom surface in close contact with the slab bottom The purpose is to prevent the backflow of odor to the wash basin or bathtub without a drain trap.

In addition, by tightening the elbow to the water collecting pipe fastener formed on the stepped bottom surface to enable the flow of the water collecting pipe installation by reducing the construction cost by enabling the straight construction of the water collecting pipe connecting the washbasin or the tub and the drain pipe device. It is another purpose to make it possible.

In addition, it is another object of the present invention to increase the amount of water loaded by using a collecting pipe as a drain trap so as to prevent odor backflow due to evaporation of sewage even without using a wash basin or a bath for a long time.
