Taking a drain pipe as an example, when the drain pipe is installed and paved, cement pouring needs to be carried out outside the pipe to wrap most of the area of the pipe, and then a waterproof layer is coated above the pouring area and a water closing test is carried out. After the water-blocking test is passed, taking the conventional tile laying as an example, mortar needs to be laid on the waterproof layer again, the tile is laid, and finally the floor drain is installed. In the construction process, especially in the water closing test stage, as part of the waterproof layer flows into the drainage pipeline, the waterproof layer is extremely easy to damage during pipe insertion and pipe drawing operation, so that gaps appear at the joint of the waterproof layer and the pipe orifice of the drainage pipeline and the vicinity thereof, and at the moment, after long-term use, part of water can infiltrate into the mortar layer through the brick joints, and enters the cement layer through the cracks of the waterproof layer and stays in the cement layer and cannot be discharged. The water-containing cement layer can cause the whole ground, wall surface and wall corner to be in a wet state for a long time, and finally wall cancer, mould and the like are formed at the ground, the wall corner, the wall surface and the like.

The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

The technical scheme of the invention is specifically described below with reference to the accompanying drawings.

The invention provides a drainage connector which mainly comprises a drainage part 1, an annular shell 2 and a limiting lug 3, wherein the drainage part 1, the annular shell 2 and the limiting lug 3 are of an integrated structure.

Specifically, the drainage part 1 has a tubular structure as a whole, and a drainage hole 11 for draining water is provided in the axial direction thereof; the annular housing 2 is formed outside one end of the drain portion 1 in the axial direction, and the annular housing 2 is connected with the outer side wall of the drain portion 1 and forms an annular groove 3; at least two limit lugs 4 are formed on the inner side wall of the drainage part 1, and a drainage groove 5 is formed between two adjacent limit lugs 4.

The annular housing 2 and the limit projection 4 are located at the same end in the axial direction of the drain portion 1 and are located outside and inside the drain portion 1, respectively.

The use mode of the drainage connector is consistent with that of the traditional drainage connector, and the drainage connector is only required to be installed on a corresponding drainage vertical pipe. When in use, the waterproof paint can flow into the annular groove 3 formed between the annular shell 2 and the drainage part 1, so that firm adhesion between the waterproof paint and the drainage joint is ensured, meanwhile, the design of the annular groove 3 can also effectively prevent the waterproof paint from flowing into the drainage hole 11 and blocking the drainage hole 11, and the problem that the joint of the waterproof layer 7 and the drainage joint is easy to leak is effectively solved on the premise of not affecting the drainage effect of a pipeline. The spacing bump 4 formed on the inner sidewall of the drainage part 1 not only can be used for spacing and supporting the corresponding water falling component, but also the drainage groove 5 can be used for discharging water penetrating between the mortar layer 8 and the waterproof layer 7, and the spacing bump 4 can also help to install a shielding structure similar to a lantern ring so as to prevent the mortar from blocking the drainage groove 5 in the tile paving process.

In general, in order to realize rapid drainage of the accumulated water, it is necessary to provide a funnel-shaped structure at one end of the drainage portion 1 close to the ground, that is, at one side of the drainage portion 1 close to the annular housing 2, an inclined surface 12 is formed on an inner side wall of the drainage portion 1, and the limit bump 4 is formed on the inclined surface 12.

The limiting projection 4 can be matched with the water falling component 10 arranged above the water draining joint, so that the limitation of the water falling component 10 is realized.

As shown in fig. 1 and 2, the drain portion 1 has a cylindrical structure as a whole, the drain holes 11 are provided so as to penetrate both ends of the drain portion 1 in the axial direction thereof, and an annular housing 2 is formed so as to surround the outer side of one end of the drain portion 1, and the end surface position of the annular housing 2 is higher than the end surface position of the drain portion 1. The annular groove 3 is formed between the annular housing 2 and the outer side wall of the drain 1. This structure can ensure that water located above the waterproof layer 7 can flow into the drain hole 11 located in the drain portion 1 through the annular housing 2. On the same side inner wall of the drainage part 1, a plurality of limit lugs 4 are formed, and the limit lugs 4 are arranged at equal intervals and a plurality of drainage grooves 5 are formed between two adjacent limit lugs 4. When the waterproof paint is brushed, the waterproof paint can flow into the annular groove 3 through the annular housing 2 and form a corresponding waterproof layer 7. The structure not only can effectively increase the contact area between the waterproof layer 7 and the drainage connector, but also can effectively isolate gaps among the cement layer 6, the drainage connector and the waterproof layer 7, thereby avoiding the possibility that accumulated water invades the cement layer 6.

In the construction stage, before the building is subjected to cement pouring, the sewer pipeline and the drainage connector are required to be installed at corresponding positions, and in the whole installation process, no additional operation is required, so that the use is more convenient.

In the cement pouring, since the annular groove 3 is formed in the drain joint, the cement can be blocked from entering the drain system through the drain hole 11 by temporarily covering the drain joint with a protective cover of a corresponding size, as shown in fig. 3. When the cement layer 6 is air-dried and hardened and needs to be subjected to waterproof treatment, the protective cover is replaced at the moment, so that waterproof paint can be ensured to flow into the annular groove 3 only, as shown in fig. 4.

As an alternative embodiment, the bottom wall of the annular groove 3 is provided obliquely and its oblique direction is inclined downward from the annular housing 2 to the drain portion 1.

In order to avoid that air or bubbles exist in the annular groove 3 filled with the waterproof material, which affects the integrity of the waterproof layer 7, in this embodiment, it is necessary to provide the bottom wall of the annular groove 3 as an inclined surface 12. At this time, when the waterproof material flows into the annular groove 3, the waterproof material slowly flows from the highest position at the bottom of the annular groove 3 to the lowest position of the annular groove 3, and in this process, the waterproof material can smoothly remove air in the annular groove 3, thereby effectively avoiding air bubbles.

In actual operation, the waterproof material can be arranged to completely fill the annular groove 3 until the upper edge of the waterproof layer 7 is level with the upper edge of the drain part 1 or higher than the upper edge of the drain part 1; of course, it is also possible to provide for the waterproofing material to only partially flow into the annular groove 3, the remaining interspace of the annular groove 3 being filled with mortar or other filler.

After the waterproof layer 7 is dried, it needs to be subjected to a water-blocking test. In the water shutoff test, the drain hole 11 needs to be blocked as shown in fig. 5. In the water closing test process, the drain hole 11 is not in direct contact with the annular groove 3, so that the operation of blocking the drain hole 11 can not damage the waterproof layer 7 and the embedded pipeline, and the integrity of the waterproof layer 7 can be effectively ensured.

After the waterproof layer 7 passes the water closing test and dries, mortar is generally paved on the waterproof layer and ceramic tiles are paved to form a ceramic tile layer 9, holes are reserved on the positions of the ceramic tiles corresponding to the drainage joints, so that the installation of the water falling component 10 is provided, the water falling component 10 is also called a floor drain, and the installation structure is shown in fig. 6. When the waterproof device is used, most accumulated water can directly flow into the drainage connector through the water falling component 10, and in the process, water can not directly contact the waterproof layer 7, so that the waterproof quality can be effectively improved, and the service life of the waterproof layer 7 is prolonged.

When the accumulated water is more or a larger gap exists between the ceramic tiles, a small part of water falling on the ceramic tile layer 9 can infiltrate into the mortar layer 8 through the gap between the ceramic tiles, the arrow in fig. 7 represents the water flow direction in the mortar layer 8, and the water in the mortar layer 8 can be blocked by the waterproof layer 7 and gradually flows to the drain holes 11 and is discharged along the guide of the waterproof layer 7, so that water stagnation is avoided. The cement layer 6 is located the waterproof layer 7 below, and water can not permeate cement layer 6 under the intact circumstances of waterproof layer 7, so can effectively protect cement layer 6, avoid ground, corner etc. to appear wall cancer scheduling problem.

In this embodiment, the design of the inclined surface 12 facilitates the rapid drainage of the water leaking into the mortar bed 8.

As an alternative embodiment, the inner side wall of the drain portion 1 further includes a vertical surface 13 formed above the inclined surface 12, and a gap 14 exists between the vertical surface 13 and the limit bump 4.

The gap 14 can also cooperate with the water fall assembly 10 to facilitate installation of the water fall assembly 10. In addition, the design of the gap 14 also facilitates the installation of a corresponding protective cover structure on the drain fitting. In the mortar laying phase, a protective cap of suitable dimensions can be placed over the drain joint through the gap 14.

It should be noted that, in the actual installation stage, an annular plastic ring structure is further sleeved at the position where the gap 14 is provided. Since the gap 14 is located at the inclined surface 12, the tight fit between the protective cover and the gap 14 cannot be achieved. The annular plastic ring can be used for being matched with the protective cover to further seal the gap 14, so that mortar is prevented from entering the drain hole 11 through the gap to block the drain hole 11.

A vertical surface 13 is connected to the lower end of the inclined surface 12, and water flowing out through the inclined surface 12 enters the drainage channel through the vertical surface 13, while water discharged through the water falling unit 10 falls directly into the drainage channel formed by the vertical surface 13, as shown in fig. 7.

In order to ensure the accuracy of the installation of the water falling assembly 10, a step 41 for supporting the water falling component is formed on one side of the limiting bump 4 near the water discharging hole 11. When the water falling part is inserted into the water draining joint, the lower edge of the middle part of the water falling part (from which water flows out) will abut against the step 41, and the peripheral side wall of the middle part will be attached to the step 41, as shown in fig. 6. The step 41 is not only used for supporting the water falling component, but also can help to fix the water falling component and prevent the water falling component from shaking relative to the water discharging joint. Since the limit protrusions 4 are formed on the inclined surface 12, the drain grooves 5 formed between two adjacent limit protrusions 4 are not affected by the water falling component, and still can drain normally, as shown in fig. 7.

It can be appreciated that the drainage connector provided by the embodiment can effectively increase the contact area between the connector and the waterproof layer 7 during use, and better separate cement and water, thereby overcoming the problem that the traditional drainage connector is easy to leak water and better protecting the ground and the wall surface.

In addition, pipelines of different configurations need to be pre-buried due to different installation environments. When the drainage joint needs to be connected with other corresponding transverse drainage pipes on the premise of meeting the requirement of normally receiving the water falling component, as an alternative implementation manner, the side wall of the drainage part 1 is also provided with a water inlet hole 15, and the water inlet hole 15 is formed in the middle of the drainage part 1 and is communicated with the drainage hole 11.

The water inlet hole 15 can be matched with a secondary water discharge structure to realize secondary water discharge, so that the water retention in the cement layer 6 and the mortar layer 8 is thoroughly prevented; or, the water inlet hole 15 can be matched with other corresponding pipelines to collect and uniformly discharge sewage at a plurality of different pipelines.

The drain hole 11 is formed in the middle of the drain part 1 and has a nozzle structure formed at the outside thereof to be matched with a corresponding pipe.

As an alternative embodiment, the number of water inlet holes 15 is at least one.

In the present embodiment, the number of the water inlet holes 15 is 4 and uniformly distributed on the side wall of the water discharge portion 1, as shown in fig. 8 and 9.

When in use, the drainage joint can be connected with corresponding pipelines which are transversely arranged and can carry out drainage treatment on the pipelines, as shown in fig. 10, and the arrow in the drawing indicates the water flow direction.

The invention also provides a drainage system comprising the drainage joint.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
