Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, and in particular to a waterproof concealed drainage component. Background Technology

[0002] In the field of building waterproofing technology, the principle of prioritizing "prevention" and supplementing it with "drainage" is followed.

[0003] Currently, although there are some secondary drainage components on the market for water accumulation in the mortar layer of building waterproofing, these components have obvious technical problems in both drainage and protection in practical applications, making it difficult to meet the long-term needs of building waterproofing.

[0004] In terms of drainage, existing secondary drainage components generally only have a single drainage channel, resulting in limited drainage capacity. As water in the dry mortar layer infiltrates, it releases calcium, which gradually accumulates in the drainage channel over time, forming a deposit of a certain thickness, eventually leading to blockage of the drainage channel.

[0005] In terms of protection, existing secondary drainage components lack effective protective structures and cannot prevent dry mortar from entering the components during construction. Once the dry mortar enters the drainage channel, it accumulates and further aggravates the blockage problem, seriously affecting the drainage effect.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a waterproof concealed drainage component to solve the technical problem that existing secondary drainage components generally only have a single drainage channel, which is difficult to effectively deal with the blockage caused by calcium release and deposition during water seepage from the dry mortar layer and the entry of dry mortar, thus leading to the inability to drain water in time and seriously affecting the drainage effect. The various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are described in detail below.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This utility model provides a waterproof concealed drainage component, including a component body. The component body has a first drainage channel on its exterior. The first drainage channel includes multiple arc-shaped guide channels and straight guide channels that are connected sequentially along the water flow direction. The arc-shaped guide channels are formed by bending in the horizontal direction, and the straight guide channels are formed by extending in the vertical direction. A second drainage channel that runs through the component body in the vertical direction is opened at the center of the component body.

[0010] Preferably, the component body includes a drainage base plate and a drainage pipe arranged concentrically from top to bottom. The outer diameter of the drainage base plate is larger than the outer diameter of the drainage pipe.

The first arc-shaped baffle and the second arc-shaped baffle are arranged alternately along the circumference of the drainage base plate, and an arc-shaped guide groove is formed between two adjacent first arc-shaped baffles and second arc-shaped baffles. A straight baffle is provided on the outer circumferential surface of the drainage pipe. The straight baffles are arranged at intervals along the circumference of the drainage pipe, and a straight guide groove is formed between two adjacent straight baffles.

[0011] Preferably, the first arc-shaped baffle is connected to the straight baffle, and the second arc-shaped baffle is not connected to the straight baffle.

[0012] Preferably, the top surface of the drainage substrate is provided with a plurality of first annular baffles and second annular baffles arranged at intervals around the inlet of the second drainage channel, and a first drainage gap is formed between two adjacent first annular baffles; the second annular baffles are located inside the first annular baffles and are staggered with them, and a second drainage gap is formed between two adjacent second annular baffles.

[0013] Preferably, the device further includes a cover plate, which is connected to the first annular baffle, and the diameter of the cover plate is larger than the diameter of the first annular baffle.

[0014] Preferably, the cover plate is provided with a knockdown plate, which is connected to the cover plate through an intermittent annular knockdown seam and is correspondingly arranged with the second drainage channel; when the knockdown plate is knocked off, the inlet of the second drainage channel is exposed, forming a space for other components to be inserted.

[0016] Preferably, it further includes a plurality of control strips, which are arranged at intervals along the circumference of the second drainage channel on the inner wall surface of the second drainage channel.

[0017] Preferably, the lower part of the control strip is provided with a limiting protrusion that protrudes in the direction toward the center of the second drainage channel.

[0018] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0019] This invention effectively solves the technical problem that existing secondary drainage components generally only have a single drainage channel, which makes it difficult to effectively deal with the blockage caused by calcium release and deposition during water seepage in the dry mortar layer and the entry of dry mortar, thus leading to the inability to drain water in time and seriously affecting the drainage effect.

[0020] The present invention provides a waterproof concealed drainage component, comprising a component body, a first drainage channel provided on the outside of the component body, the first drainage channel comprising multiple arc-shaped guide channels and straight guide channels connected sequentially along the water flow direction, the arc-shaped guide channels being formed by bending in the horizontal direction, and the straight guide channels being formed by extending in the vertical direction; a second drainage channel being provided at the center of the component body and extending in the vertical direction.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1:

[0035] like Figures 1-5 As shown, the present invention provides a waterproof concealed drainage component, including a component body, and a first drainage channel 6 is provided on the outside of the component body. The first drainage channel 6 includes multiple arc-shaped guide channels 601 and straight guide channels 602 that are connected sequentially along the water flow direction. The arc-shaped guide channels 601 are formed by bending in the horizontal direction, and the straight guide channels 602 are formed by extending in the vertical direction. A second drainage channel 7 that runs through in the vertical direction is opened at the center of the component body.

[0036] This invention features multiple first drainage channels 6 and second drainage channels 7 on the component body, forming a multi-channel drainage structure. Compared to a single drainage channel, this provides more discharge paths for accumulated water, improving drainage capacity, reducing the risk of blockage caused by calcium deposition and dry mortar ingress, and enhancing the smoothness of water drainage, thus promptly removing water accumulated on the mortar layer 15 of the waterproof layer 16. Furthermore, the multi-channel drainage structure design ensures that even if one channel becomes partially blocked, the remaining channels can continue to drain water, improving the reliability of the drainage system.

[0037] The widths of the arc-shaped guide channel 601 and the straight guide channel 602 can be flexibly set according to usage requirements to effectively and quickly drain accumulated water.

[0038] As an optional implementation, the component body includes a drainage base plate 1 and a drainage pipe 2 arranged concentrically from top to bottom. The outer diameter of the drainage base plate 1 is larger than the outer diameter of the drainage pipe 2. A first arc-shaped baffle 3 and a second arc-shaped baffle 4 are provided on the bottom surface of the drainage base plate 1. The first arc-shaped baffle 3 and the second arc-shaped baffle 4 are arranged alternately along the circumference of the drainage base plate 1, and an arc-shaped guide groove 601 is formed between two adjacent first arc-shaped baffles 3 and second arc-shaped baffles 4. A straight baffle 5 is provided on the outer circumference of the drainage pipe 2. The straight baffles 5 are arranged at intervals along the circumference of the drainage pipe 2, and a straight guide groove 602 is formed between two adjacent straight baffles 5.

[0039] Furthermore, the lower corners of the straight baffle 5 are rounded or chamfered.

[0040] The second drainage channel 7 is formed by penetrating the drainage substrate 1 and the drainage pipe 2 in a vertical direction.

[0041] like Figure 5 As shown, when the component body is installed on the drainage pipe 17, the bottom surfaces of the first arc-shaped baffle 3 and the second arc-shaped baffle 4 are in contact with the waterproof layer 16, and the drainage pipe 2 extends into the drainage pipe 17. There is a gap between the straight baffle 5 located inside the drainage pipe 17 and the drainage pipe 17. This gap provides space for the flow of accumulated water and also avoids friction and damage that may occur if the straight baffle 5 comes into direct contact with the drainage pipe 17.

[0042] The first arc-shaped baffle 3 and the second arc-shaped baffle 4 effectively prevent dry mortar and other debris from entering the component body and drainage pipe 17 during construction, reducing the possibility of debris entering the first drainage channel 6. Simultaneously, the first arc-shaped baffle 3 and the second arc-shaped baffle 4 have a certain width, and their bottom surfaces contact the waterproof layer, increasing the stress-bearing area in contact with the waterproof layer 16, preventing damage to the waterproof layer 16 and improving the integrity and durability of the waterproof system.

[0043] As an optional implementation, the first arc-shaped baffle 3 is connected to the straight baffle 5, while the second arc-shaped baffle 4 is not connected to the straight baffle 5.

[0044] As an optional implementation, a plurality of first annular baffles 8 and second annular baffles 10 are arranged at intervals around the inlet of the second drainage channel 7 on the top surface of the drainage substrate 1, and a first drainage gap 9 is formed between two adjacent first annular baffles 8; the second annular baffles 10 are located inside the first annular baffles 8 and are arranged in a staggered manner with them, and a second drainage gap 11 is formed between two adjacent second annular baffles 10.

[0045] Furthermore, the height of the second annular baffle 10 is less than the height of the first annular baffle 8. The second annular baffle is correspondingly positioned to the first drainage gap 9.

[0046] This design allows the first annular baffle 8 and the second annular baffle 10 to have a certain blocking and guiding effect. This not only prevents most dry mortar and other debris from directly entering the second drainage channel 7, reducing the risk of blockage, but also prevents water from flowing directly into the second drainage channel 7. Instead, the water passes through the first drainage gap 9 and the second drainage gap 11 in sequence before entering the second drainage channel 7, thus achieving water discharge. This increases the flow path of the water, allowing it to enter the second drainage channel 7 from multiple directions, further improving drainage capacity.

[0047] As an optional implementation, a cover plate 12 is also included, which is connected to the first annular baffle 8, and the diameter of the cover plate 12 is larger than the diameter of the first annular baffle 8.

[0048] Furthermore, the lower part of the cover plate 12 is fitted over the outside of the first annular baffle 8.

[0049] The cover plate 12 further improves the protective effect and further prevents dry mortar and other debris from directly entering the second drainage channel 7 during the construction process, reducing the possibility of debris entering the second drainage channel 7.

[0050] It should be noted that the specific specifications of the component body provided by this utility model can be flexibly set according to the specifications of the drainage pipe 17. For example, the component body provided by this utility model can be divided into two specifications: one that is compatible with a drainage pipe 17 with a diameter of 75mm and the other that is compatible with a drainage pipe 17 with a diameter of 50mm, so that it can be directly placed in the vertical section of the corresponding reserved drainage pipe 17 for use as an independent concealed drainage system.

[0051] According to relevant national waterproofing construction requirements, the drain outlet needs to be reinforced to the inner wall, resulting in an actual inner diameter smaller than its original diameter. Based on this, this invention features a targeted design for the outer diameter of the component body. The aim is to ensure sufficient clearance between the straight baffle 5 and the drainage pipe 17 when the component body is installed inside the drainage pipe 17. Even after deducting the thickness of the waterproof layer 16 extending into the drainage pipe 17, sufficient space is still available to ensure smooth and unobstructed drainage.

[0052] Specifically, for the component body that adapts to the 75mm diameter drainage pipe 17, the outer diameter of its drainage pipe 2 and straight baffle 5 is set to 60mm. Since the inner diameter of the drain outlet is reduced after the reinforcement treatment, and the thickness of the waterproof layer 16 will occupy a certain space of the drain outlet, setting the outer diameter of this part of the component body to 60mm ensures that after deducting the thickness of the waterproof layer 16, there is still sufficient space between the straight baffle 5 and the inner wall of the drainage pipe 17, allowing accumulated water to drain smoothly through this gap, ensuring efficient drainage.

[0053] Similarly, for the component body that adapts to the 50mm diameter drainage pipe 17, the outer diameter of its drainage pipe 2 and straight baffle 5 is set to 36mm. Although the reinforced water outlet and the waterproof layer 16 will occupy some space, the 36mm outer diameter design of this part ensures that after deducting the thickness of the waterproof layer 16, there is still enough space between the straight baffle 5 and the inner wall of the drainage pipe 17, allowing accumulated water to drain smoothly through this gap and ensuring efficient drainage.

[0054] Example 2:

[0055] The difference between Example 2 and Example 1 is as follows: Figures 6-8 As shown, a knockdown plate 1201 is provided on the cover plate 12. The knockdown plate 1201 is connected to the cover plate 12 through an intermittent annular knockdown seam 1202 and is correspondingly provided with the second drainage channel 7. When the knockdown plate 1201 is knocked off, the inlet of the second drainage channel 7 is exposed, forming a space for other components to be inserted.

[0056] For larger component bodies, such as those adapted to a 75mm diameter drainage pipe 17, a knock-off plate 1201 is provided on the cover plate 12. When the component body needs to be used in combination with other smaller components, the knock-off plate 1201 can be knocked off.

[0057] After the knocking plate 1201 is knocked off, smaller components, such as a 50mm diameter exposed drain pipe 18, can be easily placed into the second drainage channel 7 of the component body that is compatible with a 75mm diameter drainage pipe 17. Through this combination, two components of different sizes cooperate to form an exposed drain structure, allowing the drainage system to be flexibly adjusted according to actual needs.

[0058] As an optional implementation, the knockout plate 1201 is provided with an intermittent three-pronged knockout slot 1203, which is connected to the annular knockout slot 1202.

[0059] The combination of the three-pronged knockdown slot 1203 and the annular knockdown slot 1202 makes it easier and more efficient for operators to knock down the knockdown plate 1201.

[0060] As an optional implementation, a plurality of control strips 13 are also included, which are arranged at intervals along the circumference of the second drainage channel 7 on the inner wall surface of the second drainage channel 7.

[0061] Furthermore, the control strip 13 is correspondingly disposed on the inner wall of the second annular baffle 10 and extends vertically toward the inner wall of the drain pipe 2.

[0062] When the 50mm diameter surface drain pipe 18 is inserted into the second drainage channel 7, a gap is formed between them due to the presence of the control strip 13. These gaps prevent the drain pipe 17 from completely fitting against the inner wall of the second drainage channel 7. During drainage, water can pass smoothly through these gaps, increasing the drainage path and improving the reliability and efficiency of the drainage system.

[0063] As an optional implementation, the lower part of the control strip 13 is provided with a limiting protrusion 14 that protrudes in the direction toward the center of the second drainage channel 7.

[0064] When the 50mm diameter surface drain pipe 18 is inserted into the second drainage channel 7, the limiting protrusion 14 can limit the drain pipe 2 to prevent it from being over-inserted, so as to ensure the accurate connection position between the two components.
