Description

drainage apparatus

The present invention relates to a drainage device, and more particularly, to a drainage device having maximized leakage prevention performance.

Generally, when constructing a drainage device on the floor of a building, the drainage device is connected to the drainage pipe formed in the slab. The slab surface is waterproofed, sand is laid, and tiles are constructed on top of it, and the drainage device is buried. The drainage device inlet is formed at a level with the tile surface or slightly lower, and a strainer is installed to filter out foreign substances.

However, in the structure mentioned above, water flowing on the floor seeps into the sand layer through the gaps between the tiles or between the drainage device and the tiles. This water that seeps in not only accumulates in the slab and causes water leaks, but also rots over time, producing a bad smell and creating an unsanitary condition as mold grows, causing various other problems.

Republic of Korea Utility Model Registration (Y1) No. 20-0224178 (announced on May 15, 2001)

The purpose of the present invention is to propose a drainage device that prevents water flowing on the floor of a building from seeping into a sand layer and, even if water seeps in to a certain extent, allows the water that has seeped in to be drained through a drain pipe, thereby suppressing the occurrence of bad odors and mold and maintaining a sanitary condition.

The present invention proposes a drainage device including a nut body having a connecting hole through the center and through holes perforated throughout the body that covers the inlet of a drainage hole formed on the floor, a connecting pipe that is height-adjustably connected to the connecting hole and embedded in a sand layer, and a pedestal formed along the upper edge of the connecting pipe for supporting a tile, wherein the pedestal has a vertical wall and a horizontal plate, and the horizontal plate has a structure that is concave downward to form a gap between the tile and the nut body, and a hole is formed in the vertical wall that communicates with the bottom of the horizontal plate, so that water that seeps through the gap formed between the tile and the vertical wall is drained through the hole to the connecting pipe, while water that seeps into the sand layer is drained through the hole.

According to the drainage device of the present invention, by installing it on the floor of a building, it is possible to effectively prevent water from seeping into the sand layer on top of the tiles, and even if water seeps into the sand layer, it is possible to guide it to a drain and let it flow away, thereby maximizing the water leakage prevention performance and suppressing the occurrence of bad odors and mold, thereby helping to maintain a sanitary condition.

In the present invention, in order to prevent water flowing on the floor of a building from seeping into the sand layer and, even if it seeps to a certain extent, to allow the water to drain through a drain pipe, the occurrence of bad odor and mold is suppressed, thereby maintaining a sanitary condition.

The present invention proposes a drainage device including a drainage body having a nut body having a connecting hole through the center and through holes perforated throughout the body while covering the inlet of a drainage hole formed on the floor, a connecting pipe that is height-adjustably connected to the connecting hole and embedded in a sand layer, and a pedestal formed along the upper edge of the connecting pipe for supporting a tile, wherein the pedestal has a vertical wall and a horizontal plate, and the horizontal plate has a structure that is concave downward to form a gap between the tile and the drainage device, and a pedestal is formed in the vertical wall that communicates with the bottom of the horizontal plate, so that water that seeps through the gap formed between the tile and the vertical wall is drained through the pedestal to the connecting pipe, while water that seeps into the sand layer is drained through the pedestal.

Hereinafter, the present invention will be described in detail with reference to the attached drawings, FIGS. 1 to 5.

FIG. 1 is an exemplary drawing showing the main configuration of a drainage device according to the present invention, FIG. 2 is an exemplary drawing showing a cross-sectional state of a joint of a drainage device according to the present invention, FIG. 3 is an exemplary drawing showing an installation state of a drainage device according to the present invention, FIG. 4 is an exemplary drawing showing a path through which water is drained by enlarging part A of FIG. 3, and FIG. 5 is an exemplary drawing showing another embodiment of a drainage pipe according to the present invention.

As described above, the drainage device according to the present invention is installed in a drainage hole (420) formed on the floor, including a nut body (200) and a drainage body (100). The drainage hole (420) may be formed as a pipe on the floor (400) of a building, but is not limited thereto, and the floor (400) may be a slab forming a floor of a building, but is not limited thereto.

The nut body (200) has a tubular shape as a whole, and a connecting hole (220) penetrating the inside is formed. The nut body (200) is formed in a structure in which the lower end is connected to the entrance of the drain (420). This can be achieved through a structure that becomes thinner from the bottom to the top, and a structure that becomes thinner as it goes up can be formed, like a cone.

It is preferable that the lower part of the nut body (200) be formed in a shape that spreads outward while forming a gentle curve. This is a configuration adopted to sufficiently cover the entrance of the drain (420) widely and increase the contact area with the sand layer (500), and is a configuration that can be adopted to allow water that has seeped between the sand layer (500) and the nut body (200) to flow down along the gentle curve.

The nut body (200) is perforated with holes (224). They are formed in a predetermined pattern over the entire lower portion. When screw threads are formed on the inner surface of the nut body (200), the holes (224) are formed in the remaining portion except for the point where the screw threads are formed. Furthermore, it is preferable that the holes (224) are formed on the lower edge of the nut body (200) so that water can flow smoothly into the drain (420) at the point where it comes into contact with the floor (400).

The drain body (100) is formed with a connecting pipe (120) that is connected to a nut body (200).

The connecting pipe (120) has a pipe shape and has screw threads formed on the outer surface to form a screw connection with the nut body (200). Therefore, the height of the drain body (100) can be naturally adjusted by tightening and loosening the screw. The connecting pipe (120) is placed in a sand layer (500) during the process of constructing the drainage device according to the present invention on the floor.

A support (140) is formed along the edge of the upper portion of the connecting pipe (120). The support (140) is formed in a structure similar to a frame being formed while forming a predetermined width. Water flowing from the floor flows into the connecting pipe (120) through the inner area of the support (140), and a strainer (not shown) is installed so that foreign substances are filtered out and the water is discharged.

The pedestal (140) serves to support the tile (600). Accordingly, the pedestal (140) can be formed by including a vertical wall (142) and a horizontal plate (146).

The vertical wall (142) is a part that comes into contact with the end of the tile (600), and mortar is applied to fill the gap between the vertical wall (142) and the tile (600). For this purpose, it is preferable that the height of the vertical wall (142) be formed to match the thickness of the tile (600).

The horizontal plate (146) supports the tile (600) from below and has a concave structure downward. The end is bent upward to form a concave structure downward. In this configuration, when the tile (600) is placed on it, a gap is formed between the tile (600) and the bottom surface of the tile (600).

Here, a perforation (144) is formed in the vertical wall (142). The perforation (144) is formed in such a way that the lower end is connected to the bottom of the horizontal plate (146). Therefore, when water seeps through the gap between the vertical wall (142) and the tile (600), it flows into the concave point in the horizontal plate (146) and then flows into the drain body (100) through the perforation (144) and is discharged through the drain outlet. At this time, since the horizontal plate (146) is formed concavely, water that seeps into the concave point does not flow out to other places but only flows out through the perforation (144).

The present invention may further include a fitting (300) fitted into a drain (420) formed on the floor (400).

The fitting (300) has a structure in which a frame plate forming a horizontal frame is formed at the top. When the fitting (300) is fitted into the drain (420), the frame plate is caught on the entrance of the drain (420). At this time, it is preferable that the fitting (300) and the drain (420) and the frame plate and the entrance of the drain (420) be constructed so that they are in close contact with each other to maintain airtightness.

Hereinafter, construction examples of the drainage device according to the present invention as described above will be described. The construction status is shown in Figs. 3 and 4.

A drain (420) is formed on the floor (400) of the building. The drain (420) may have a pipe installed, and the floor (400) may be formed in a state of sloping downward toward the drain (420) so that water can flow toward the drain (420). Waterproofing is performed on the floor (400). The waterproofing may be performed by applying a waterproofing agent, and the method is not limited to a specific one.

Afterwards, the insert (300) is inserted into the drain (420). It is preferable to apply adhesive or the like to the contacting portions to ensure that the insert (300) and the drain (420) and the frame plate and the inlet of the drain (420) are in close contact with each other. This prevents moisture from seeping into the gap between the insert (300) and the drain (420). Depending on the situation, the insert (300) may not be installed.

Next, the drain body (100) is installed while the nut body (200) is connected to the connecting pipe (120). The connecting pipe (120) is inserted into the drain port (420), and at this time, the nut body (200) is hung on the drain port (420) entrance while widely covering the drain port (420) entrance. As a result, the position of the drain body (100) is determined. Meanwhile, in this state, the nut body (200) is rotated or the drain body (100) is rotated to appropriately adjust the height of the drain body (100).

When the height of the drainage body (100) is adjusted, sand is laid on the floor (400) to form a sand layer (500). This is for installing the drainage body (100) and constructing tiles (600). In this process, the nut body (200) can be covered with pebbles (520). The pebbles (520) are larger than the holes (224) formed in the nut body (200). These pebbles (520) prevent sand from leaking out through the holes (224) formed in the nut body (200) during the process of applying the sand, but allow water to leak out through the holes (224).

When the sand layer (500) is formed through the above process, tiles (600) are constructed on the surface of the sand layer (500). At this time, waterproofing can be performed on the surface of the sand layer (500) before constructing the tiles (600). This waterproofing can be performed by applying a waterproofing solution, but is not limited thereto.

Meanwhile, on the upper part of the drain body (100), construction is performed with the edge of the tile (600) resting on the pedestal (140). Construction is performed with the edge of the tile (600) resting on the horizontal plate (146) forming the pedestal (140), and when construction is performed in this manner, the upper surface of the tile (600) and the upper part of the vertical wall (142) become horizontal. In this process, it is desirable to construct the tile (600) so that the surface of the tile (600) slopes downward to a certain degree toward the inlet of the drain body (100), which is to allow water to flow naturally into the drain body (100).

The drainage device according to the present invention constructed as described above prevents water from seeping into the sand layer (500) by allowing water that seeps between the tile (600) and the vertical wall (142) to flow into the connecting pipe (120) through the perforation (144) and be drained. Furthermore, even if some of the water seeps into the sand layer (500), it flows downward within the sand layer (500) and then flows into the drain (420) through the perforation (224) formed in the nut body (200) and is then drained. Accordingly, water can be effectively prevented from seeping into the sand layer (500), and the water that has seeped in is quickly drained, thereby suppressing the occurrence of odors and mold, thereby maintaining a sanitary condition.
