Description

A double-layer drainage floor drain for assembled dry construction

Technical Field

The invention relates to the field of building drainage, and in particular to an assembled double-layer drainage floor drain for dry construction.

Background technique

In traditional same-floor drainage construction, bathroom floor drains are buried underground, and pipes are also buried underground. They are filled with cement mortar. The floor drain grate is flush with the tile surface. The accumulated water flows from the ground into the grate and into the pipe for drainage. In order to prevent surface water from seeping into the ground, a waterproof layer is generally required under the tiles. The joints between the floor drain and the tiles are also filled with special waterproof cement to prevent ground water from seeping into the ground.

In prefabricated dry construction, cement mortar is basically not used on site. The floor is generally elevated, and the pipes are placed in the elevated layer. The materials are assembled on site. The installation order is to first arrange the pipes on the floor, put the support feet, and then put the support plate (the main load-bearing component used to bear the ground load) on the support feet. The waterproof chassis is installed on the support plate, and the quick-install tiles are laid on the waterproof chassis. Finally, the tile joints are sealed. In order to prevent ground water from seeping into the elevated layer, the drainage in the elevated layer needs to be sealed and connected with the waterproof chassis when passing through the waterproof chassis. At the same time, the joints between the floor drain grate and the tiles must also be sealed. The existing prefabricated dry construction has the following problems: due to the elevated ground, deformation and displacement are inevitable during use, the sealing of the joints of the floor tiles will fail, and the ground water is easy to seep into the interlayer between the tiles and the waterproof chassis. After a long time, especially in summer, it will stink and cause the bathroom odor problem. The bathroom is prone to odor.

Summary of the invention

The present invention aims to solve the problem that the sealing of the joints of floor tiles may fail after a period of use, resulting in water accumulation in the interlayer, and provides a double-layer drainage floor drain for assembled dry construction. The double-layer drainage floor drain can not only drain the water on the ground, but also drain the leaked water on the waterproof chassis, thereby solving the problem of the leaked water accumulating underground for a long time and causing stink in the existing practice.

To achieve the above object, the present invention adopts the following technical solution: an assembled double-layer drainage floor drain for dry construction, the double-layer drainage floor drain comprising:

A main body, the main body is located at the bottom and has a drainage channel;

An interlayer water seepage collection component, the interlayer water seepage collection component is sealed to the waterproof chassis sealing component, and the interlayer water seepage collection component has a leakage water collection port;

A ground water collection component, the ground water collection component is sealed and connected to the interlayer seepage water collection component, the ground water collection component has a ground water collection port, and the ground water collection port is located above the seepage water collection port;

The leakage water collection port of the interlayer seepage water collection component is communicated with the water flow channel of the water seal component and the drainage channel of the main body, and the ground water collection port of the ground surface water collection component is communicated with the water flow channel of the water seal component and the drainage channel of the main body.

The double-layer drainage floor drain of the present invention is used in installed dry construction, and has a ground water collection port and an interlayer water collection port, which can not only drain the ground water, but also drain the leaked water on the waterproof bottom plate, thereby solving the odor problem caused by the long-term accumulation of leaked water in the interlayer in the existing practice.

As an improvement, the main body includes a bowl-shaped body and a laterally extending drainage interface connected to the bowl-shaped body. The bowl-shaped body has an inclined surface inclined relative to the horizontal plane, and the lowest point of the inclined surface is connected to the lowest point of the inner cavity of the drainage interface; the upper edge of the bowl-shaped body has an internal threaded portion for threaded connection with the waterproof chassis sealing component, and the upper end of the internal threaded portion extends outward to form a sealing plane. The setting of the inclined surface can ensure that sewage can be discharged to the drainage interface in time. The upper end of the internal threaded portion extends outward to form a sealing plane. When the fastening cover is tightened, a pressing force will be formed between the sealing plane and the sealing surface of the fastening cover, pressing the seal to form a seal between the floor drain and the waterproof chassis. When there is water leakage in the interlayer between the waterproof chassis and the quick-install tiles, it will not flow under the waterproof chassis. At the same time, the threaded connection part of the fastening cover and the main body is also sealed to ensure that the odor in the pipeline will not overflow from the threaded connection part.

As an improvement, the bowl-shaped body also extends to form a columnar portion with an opening at the upper end, the columnar portion has a horizontal inner bottom surface, the inner bottom surface is lower than the lowest point of the inclined surface, the lower end of the water seal assembly is accommodated in the columnar portion, and the depth of the water seal assembly extending into the interior of the columnar portion after being installed in place is not less than 50 mm. After the water seal assembly is installed in place, the depth of the water seal assembly extending into the interior of the columnar portion is not less than 50 mm, thereby forming a water seal structure of sufficient depth, which can prevent the odor in the pipeline from passing through the water seal and overflowing upward from the inside of the water seal sleeve into the room. The inner bottom surface of the columnar portion is lower than the lowest point of the inclined surface, so that the volume is as small as possible under the premise of ensuring the depth of the water seal.

As an improvement, the waterproof chassis sealing assembly includes a fastening cover and a sealing member, the fastening cover includes an external threaded portion for threaded connection with the body, a tightening portion extending outward from the top of the external threaded portion, a tightening slot is provided on the outer periphery of the tightening portion, and the cross section of the sealing member has a groove for matching with the waterproof chassis. The provision of the tightening slot facilitates the positioning of the tool when the fastening cover is screwed in.

As an improvement, the middle position of the external thread portion in the height direction extends inward to form an annular portion, the inner end of the annular portion extends downward to form an inner hole and a limit step at the bottom of the hole, and the water seal assembly is arranged in the inner hole; the waterproof chassis sealing assembly also includes a gasket arranged between the fastening cover and the sealing member in the height direction. The gasket can reduce the friction between the sealing member and the annular portion of the fastening cover.

As an improvement, the water seal assembly includes a water seal sleeve and a water seal ring. The water seal sleeve is tubular, and the upper end of the water seal sleeve has a protrusion, and the side of the protrusion is provided with an annular groove, and the water seal ring is embedded in the annular groove. The bottom of the protrusion at the upper end of the water seal sleeve forms a limiting step; the inner wall of the water seal sleeve extends to form a rib structure for lifting and disassembly. The limiting step of the water seal sleeve cooperates with the limiting step of the fastening cover to prevent the water seal sleeve from falling. The rib structure is used to pull up and disassemble the water seal sleeve when cleaning garbage in the water seal cavity of the floor drain.

As an improvement, the sandwich water seepage collection assembly includes a water seepage collection piece, the water seepage collection piece has an upper tube portion, a lower tube portion and a horizontal portion, the outer diameter of the upper tube portion is smaller than the outer diameter of the lower tube portion, the horizontal portion is provided with a plurality of leakage holes evenly distributed around the circumference, the plurality of leakage holes form the leakage water collection port, the lower tube portion is sealed and connected to the water seal assembly; the water seepage collection piece extends inside to form a guide portion. The guide portion may be funnel-shaped, used to guide the water flow to be discharged to the middle of the pipeline to avoid entering the water channel of the leakage hole.

As an improvement, the interlayer water seepage collection assembly also includes an anti-overflow component that can move up and down, the material density of the anti-overflow component is less than the density of water, the anti-overflow component is an annular structure, the upper end of the anti-overflow component has a sealing surface that can seal the leakage hole, the anti-overflow component has a plurality of circumferentially evenly distributed protrusions that protrude downward, the gaps between the protrusions form a water passage, the upper tube portion extends downward to form a guide portion located below the guide portion, and there is a gap between the anti-overflow component and the lower tube portion. The leakage water in the interlayer can enter from the leakage hole and enter the water seal sleeve through the gap between the anti-overflow component and the lower tube portion and the gaps between the protrusions. When the pipeline is blocked, or the floor drain is too large to cause the floor drain to be full of water, and the water level is higher than the height of the drainage hole, the channel from the drainage hole to the drainage pipe will be filled with water. Since the material density of the anti-overflow component is less than the density of water, the anti-overflow component will float up at this time to block the water seepage hole, so that the water in the floor drain will not flow back into the interlayer.

As an improvement, the ground water collection assembly includes a connecting piece and a water sealing ring, the lower part of the connecting piece has an annular groove, and the water sealing ring is embedded in the annular groove. The connecting piece can move up and down relative to the seepage water collection piece, so that the surface layer height can be adjusted.

2. Place appropriate number of overhead support legs 7 at appropriate positions according to load requirements and adjust the height.

3. Place the structural support plate 8 on the support feet and make a reserved hole at the position of the double-layer drainage floor drain.

4. Place the waterproof chassis 9 on the support plate 8, and insert the "U"-shaped groove of the seal 22 of the double-layer drainage floor drain into the prefabricated countersunk hole of the waterproof chassis 9, then put in the gasket 23 and the fastening cover 21 in turn, and tighten the fastening cover 21, and then install the floor drain water seal assembly 3 and the interlayer seepage collection assembly 4 in turn.

5. Lay quick-install tiles 10 on the waterproof chassis 9 and reserve countersunk holes at the double-layer drainage floor drain.

6. Insert the ground water collection component 5 into the seepage water collection component.

7. Perform sealing treatment between the connecting piece 51 and the reserved hole of the quick-install tile 10.

The working principle of the present invention is as follows: when there is water leakage in the interlayer between the waterproof chassis 9 and the quick-install tile 10, the leaking water will enter the inside of the pipe through the leakage hole. When the pipe is blocked, or the floor drain is filled with water due to excessive drainage, and the water level is higher than the height of the leakage hole, the channel from the leakage hole to the drain pipe will be filled with water. Since the material density of the anti-backflow component 42 is less than the density of water, the anti-backflow component 42 will float up at this time to block the leakage hole, so that the water in the double-layer drainage floor drain will not flow back into the interlayer.
