Description

Technical Field

[0001] This utility model relates to the technical field of bathroom decoration, and in particular to a dual-point barrier-free drainage floor. Background Technology

[0002] In bathroom renovations, especially in shower room floor design, drainage structure and pedestrian safety are always core requirements. However, existing technical solutions generally have shortcomings that make it difficult to achieve both simultaneously. Specific issues are as follows: 1. Obstacles in Conventional Shower Enclosure Floors: Traditionally, a water-retaining barrier is installed between the wet and dry areas of a shower enclosure to prevent water overflow. Simultaneously, to facilitate drainage, the shower floor needs a slope towards the drain (such as the industry-standard 3% slope), and small-sized tiles (e.g., 300×300mm) are often used. This structure, with its protruding water-retaining barrier and uneven slope, directly creates obstacles for the elderly, children, and disabled individuals, easily leading to tripping, falls, and other safety hazards, failing to meet the needs of barrier-free access.

[0003] 2. Height difference defects in modern minimalist design: Although some modern minimalist style decorations attempt to lower the overall height of the shower room to the building's zero elevation, or use a complete ceramic, artificial stone, or marble shower tray, they still fail to solve the problems of uneven floor in the shower area (such as tray splicing seams and local protrusions) and hidden height differences between wet and dry areas, which still affect the comfort and safety of passage.

[0004] 3. Limitations of grooved marble shower trays: Although traditional grooved marble shower trays are designed with a water return groove structure, which is somewhat similar to the drainage groove concept of this application, they still need to rely on water-blocking strips or height differences to achieve dry and wet separation, and a groove structure will be formed between the dry and wet areas. This groove not only damages the flatness of the ground, but also easily accumulates dirt, and still cannot eliminate passage obstacles, which does not meet the core requirements of barrier-free design.

[0005] 4. Inefficiency of separate drainage systems for wet and dry areas: In existing technologies, separate floor drains are usually required for wet and dry areas of the bathroom (such as one floor drain under the sink in the dry area and one floor drain in the shower area in the wet area). The two drainage systems are not connected to each other, resulting in scattered drainage paths, low efficiency, and increased complexity of pipe laying and decoration costs.

[0006] In view of the shortcomings of the existing technology, there is an urgent need for a bathroom floor structure that can enable barrier-free passage in wet and dry areas, integrate the drainage system, and improve drainage efficiency. Utility Model Content

[0007] This utility model aims to at least partially solve one of the technical problems in the related art.

[0008] Therefore, the purpose of this utility model is to propose a dual-point barrier-free drainage floor, with the dry and wet areas at the same elevation, without water-blocking stones or additional slopes, completely eliminating passage obstacles and significantly improving the safety of passage for the elderly, children, and disabled people; the drainage channel component connects the long strip concealed floor drain and the round filter floor drain, realizing the sharing of the drainage system in dry and wet areas, reducing the number of floor drains and pipes to reduce costs, and the multi-directional drainage slope improves the efficiency of water drainage; the long strip concealed floor drain cover fits the ground material for a visually integrated look, and a wide range of decorative materials can be selected to meet both aesthetic and style requirements; the underlying leveling layer and waterproof layer meet the specifications, preventing water seepage and extending service life.

[0009] To achieve the above objectives, this utility model proposes a dual-point barrier-free drainage floor system comprising a dry area floor, a wet area floor, a drainage channel assembly, a long, concealed drain, and a circular filter drain. The dry area floor and the wet area floor are adjacent to each other, and after installation, they maintain a barrier-free, level condition with no height difference, and are at the same elevation. The long, concealed drain is embedded at the junction of the dry and wet areas, and includes a concave inlet and a concealed cover. The concealed cover is embedded within the decorative material of both the dry and wet areas, and its elevation is consistent with that of both floors. The long, concealed drain also connects to a pre-installed drain outlet in the bathroom. The circular filter drain is embedded in the wet area floor near the corner of the showerhead, and includes a... The system includes a grating cover and a filter screen. The grating cover is level with the lowest point of the drainage trough assembly. The circular filter screen drain is connected to a pre-installed drain in the bathroom. The drainage trough assembly includes drainage trough A, drainage trough B, and drainage trough C. Drainage trough A is positioned along the length of the elongated concealed drain and communicates with its concave inlet hole. The lowest point of drainage trough A is at the center of the elongated concealed drain. Drainage troughs B and C are both located within the wet area floor. One end of each is connected to the circular filter screen drain, and the other end is connected to drainage trough A. The lowest point of the intersection of drainage troughs B and C is at the circular filter screen drain, while the highest point is at the intersection of drainage troughs A and B. The drainage trough assembly integrates drainage channels for both dry and wet areas, enabling a shared drainage system.

[0010] This utility model features a dual-point barrier-free drainage floor with consistent elevation in both dry and wet areas. It eliminates water-blocking stones and additional slopes, completely removing access barriers and significantly improving safety for the elderly, children, and disabled individuals. The drainage channel assembly connects a long, concealed drain and a circular filter drain, enabling shared drainage systems in both dry and wet areas. This reduces the number of drains and pipes, lowering costs, while the multi-directional drainage slope improves water drainage efficiency. The long, concealed drain cover seamlessly integrates with the floor material, offering a wide range of decorative material options to meet both aesthetic and style requirements. The underlying leveling and waterproofing layers meet specifications, preventing water seepage and extending service life.

[0011] In addition, the dual-point barrier-free drainage floor proposed in the application may also have the following additional technical features: Specifically, the length of the long, concealed floor drain can be adjusted according to the size of the bathroom and the needs of the users, and the concealed cover of the long, concealed floor drain is fitted with the decorative materials of the dry area floor and the wet area floor to achieve a unified visual appearance of the floor.

[0012] Specifically, the circular filter drain is circular in shape, and the filter screen of the circular filter drain can filter the water entering the drain to prevent impurities from entering the sewer pipe.

[0013] Specifically, the width of the drainage trough A is 50-80mm, the width of the drainage troughs B and C is 80mm, and the width of the drainage trough A is less than or equal to the width of the long strip concealed floor drain. The widths of the drainage troughs B and C are adapted to the size of the circular filter floor drain to ensure that water can flow smoothly into the floor drain.

[0014] Specifically, a waterproof layer and a leveling layer are provided under the dry area floor and the wet area floor. The leveling layer is used to make the ground base flat, and the waterproof layer is used to prevent water seepage into the bathroom floor. Together, they provide basic protection for the laying and drainage functions of the dry area floor and the wet area floor.

[0015] Specifically, a glass partition can be installed in the wet area corresponding to the shower area, and the joint between the glass partition and the wet area floor is kept flat.

[0016] Specifically, edge trim strips can be provided on the sides of the decorative materials of the dry area floor and the wet area floor. The edge trim strips are used to optimize the floor decoration effect and do not affect the barrier-free passage of the floor.

[0017] The advantages of this invention compared to existing technologies are as follows: (1) By designing that the ground elevation of the dry area and the ground elevation of the wet area are consistent, without water-blocking stones and without additional slope, the passage obstacles in the traditional structure are completely eliminated, significantly improving the passage safety of the elderly, children and disabled people, and avoiding the hidden dangers of tripping and falling.

[0018] (2) By using the drainage channel assembly to connect the long strip concealed floor drain and the round filter floor drain, the drainage system of the dry area and the wet area can be shared. This not only reduces the number of floor drains and pipes and lowers the decoration cost, but also improves the efficiency of water drainage through the multi-directional drainage slope design and avoids water accumulation on the ground.

[0019] (3) The cover of the long strip invisible floor drain is integrated with the floor decoration material to achieve visual integration; the filter of the round filter floor drain can hide impurities, and the width of the drainage groove component is adapted to the size of the floor drain, without damaging the overall aesthetics of the floor. At the same time, the range of decorative materials is wide to meet the needs of different decoration styles.

[0020] (4) The leveling layer and waterproof layer below provide basic support and waterproof protection for the overall structure, which complies with the national bathroom decoration specifications, avoids water seepage problems, and extends the service life of the drainage floor.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The following description, in conjunction with the accompanying drawings, describes a dual-point barrier-free drainage floor according to an embodiment of the present invention.

[0026] like Figures 1-4 As shown, the dual-point barrier-free drainage floor of this utility model embodiment includes a dry area floor 1, a wet area floor 2, a drainage channel assembly 3, a long strip concealed floor drain 4, and a circular filter floor drain 5.

[0027] Example 1: Detailed Implementation of Each Technical Feature (I) Construction Implementation of Dry Area Ground 1 and Wet Area Ground 2 1. Initial grassroots processing First, clean the original bathroom floor (original reinforced concrete floor slab): remove surface dust, cement residue and protruding debris, grind it with a wire brush until rough, rinse with clean water and let it dry before proceeding to the next step.

[0028] Leveling layer construction: A 1:3 cement mortar (medium sand with a mud content ≤3%) is used to lay the leveling layer. The thickness is based on ensuring that the elevation reaches ±0 after the subsequent floor decoration materials are laid. During construction, a straightedge is used to level the surface and the surface is vibrated to ensure compaction and prevent hollow areas. After completion, the surface is covered with geotextile and watered for curing. The curing period is no less than 3 days, during which time walking on the surface is prohibited.

[0029] Waterproofing layer construction: After the leveling layer dries, apply a polymer cement-based waterproof coating conforming to GB / T23445-2017 standard. First, reinforce key areas such as wall corners and around drains. The overall waterproofing layer is applied in two coats; apply the second coat after the first coat has dried, with a total thickness of 1.5mm. After the waterproofing layer has stood for 24 hours, conduct a water tightness test: fill the water to a depth of 50mm above the ground and observe continuously for 24 hours. Construction can only continue after confirming there is no leakage.

[0030] 2. Decorative material installation and elevation control Use 1200×600mm, 1500×800mm, or custom-made large-format ceramic tiles (sintered stone, artificial stone, or micro-cement can be substituted) as the decorative material, and follow the requirement of "no height difference between dry and wet areas, and uniform elevation of ±0": Adhesive layer preparation: Use dry hard cement mortar (cement: sand = 1:3, add appropriate amount of water to adjust to the state of "can be formed into a ball when squeezed in the hand, and crumbles when dropped"), and apply interface agent to the surface of the waterproof layer before laying to improve adhesion.

[0031] Laying sequence: Lay from the dry area away from the shower area towards the wet area. Use a level to calibrate the elevation of each tile to ensure it is flush with the adjacent tiles. Leave gaps to be filled with grout later. If there is a local elevation deviation, correct it by adjusting the thickness of the adhesive layer. Finally, the overall flatness error of the dry area floor 1 and the wet area floor 2 is ≤2mm, which meets the "no height difference" requirement for barrier-free passage.

[0032] (II) Installation and Implementation of Long Strip Concealed Floor Drain 4 1. Positioning and Preprocessing Based on the actual dimensions of the bathroom, the embedding position of the long strip concealed floor drain 4 is determined to be "the dry and wet separation boundary line directly below the center of the shower room door": use a chalk line to mark the door frame line and the boundary line, and take the midpoint to determine the floor drain installation axis (coinciding with the boundary line).

[0033] Select a long, concealed floor drain with dimensions of 650-900mm × 80-90mm. Before installation, cut concave water inlet holes at both ends of the drain to ensure that water can flow in quickly without damaging the drain structure.

[0034] Considering that ordinary strip floor drains do not have water inlet channels on the sides, it is necessary to process the side cuts of the long strip concealed floor drain 4 before installation. When processing the cuts, the water inlet cuts should be processed on both the left and right sides along the length of the long strip concealed floor drain 4. At the same time, the edges of the cuts should be sanded smooth to prevent scratching the floor decoration materials or causing people to bump into them during later use. The processing method is to use a small benchtop cutting machine equipped with a diamond cutting disc for precise cutting. In addition, when the cuts are connected to the drainage channel, the subsequent installation must ensure that the side cuts are aligned with the wall of the drainage channel A to form a complete water inlet channel and avoid water accumulation gaps. After installation, water should be injected into the drainage channel A to observe whether the water can flow quickly into the floor drain through the side cuts to ensure that the cut function is effective.

[0035] 2. Embedding and Fixing Grooving: Cut the floor decoration material and base layer along the installation axis to form an installation groove that matches the shape of the floor drain. Clean the debris in the groove and wipe it clean.

[0036] Connect the drain outlet: Put the rubber sealing ring on the lower end of the drain core and insert it into the preset first drain outlet (which has been modified in the early stage), ensuring that it is coaxial and that the sealing ring is tightly attached to the inner wall of the drain outlet to prevent water leakage.

[0037] Cover plate installation: Insert the concealed cover plate (the same color as the tile) into the installation groove, adjust the position so that the edge of the cover plate is aligned with the tile gap, and the upper surface is at the same elevation (±0) as the dry area floor 1 and wet area floor 2. Fill the bottom with waterproof sealant to fix it.

[0038] (III) Installation and Implementation of Circular Filter Screen Floor Drain 5 1. Positioning and grooving The installation location for the round filter drain 5 is determined to be "near the corner below the shower head". Available sizes are 80mm×80mm, 90mm×90mm, and 100mm×100mm, and the shape can be round or square. Based on the selected size and shape, use a suitable cutting tool to cut the ground at the designated location to create an installation hole that perfectly matches the drain. After cleaning any debris from the hole, carefully check the alignment of the bottom of the hole with the pre-set second drain outlet to prevent subsequent drainage problems or leaks.

[0039] 2. Filter screen installation and cover plate fixing Filter assembly: Insert the stainless steel filter (with an appropriate pore size to prevent impurities) into the bottom of the grille cover, ensuring that the clips are securely fastened to prevent it from falling off.

[0040] Floor drain fixing: Place the floor drain with the filter screen installed into the installation hole, adjust the height so that the upper surface of the grille cover is flush with the lowest point of the drainage groove assembly 3, insert the sealing ring at the bottom into the second drain outlet, and fix the gap with waterproof sealant.

[0041] Function verification: Pour water containing debris into the drain to confirm that the filter can intercept impurities and that the water can flow smoothly into the pipe.

[0042] (iv) Construction and implementation of drainage trough component 3 1. Construction of Drainage Channel A Drainage channel A is installed along the length of the long, concealed floor drain 4, with a width of 50-80mm. Grooving and positioning: Using the installation axis of the long drain as the center, cut out a rectangular groove with a depth lower than the dry area floor 1 and the wet area floor 2 to ensure that water can flow in.

[0043] Tank wall treatment: Smooth the tank wall with 1:2 cement mortar, align the two ends of the tank with the concave water inlet of the long strip floor drain, and fill the joint with waterproof mortar to prevent leakage.

[0044] Slope control: The center of the long drain is the lowest point. Adjust the slope of the bottom of the groove to ensure that the water flows towards the long drain.

[0045] 2. Construction of Drainage Channel B and Drainage Channel C Drainage channels B and C are installed within the wet area floor 2, with one end connected to the circular filter drain 5 and the other end connected to drainage channel A, with a width of approximately 80mm. Grooving direction: Drainage grooves B and C extend from the circular floor drain to both ends of drainage groove A, and are cut to form rectangular grooves with the same depth as drainage groove A.

[0046] Connection and slope: The lowest point is at the intersection of drainage channels B and C with the round floor drain (at the round floor drain), and the highest point is at the intersection with drainage channel A. Use a level to calibrate the slope section by section to ensure that the accumulated water flows towards the round floor drain.

[0047] Overall connectivity verification: Sprinkle water on the ground in the wet area 2 and observe that the water flows into the circular floor drain along drainage channels B and C, and some water flows into the long floor drain along drainage channel A, confirming that drainage channel component 3 achieves "shared drainage system between dry and wet areas".

[0048] (v) Supplementary Implementation 1. Installation of glass partitions Install a glass shower screen in the shower area of ​​wet area 2, ensuring that the connection point with wet area 2 is flat during installation: Pre-embedded slots: Pre-embed glass slots along the installation location of the shower screen. The top of the slots should be at the same level as the ground (±0). Fix them with cement mortar to ensure they are vertical and without tilt.

[0049] Glass installation: Insert the glass shower screen into the slot, fill the gap between the bottom and the slot with waterproof sealant, and seal the joint between the glass and the wall with sealant to ensure no leakage and no protrusion at the joint, so as not to affect barrier-free passage.

[0050] 2. Installation of edge trim Install L-shaped edging strips (metal material) at the tile joints in dry area 1 and wet area 2, as well as at the junction of the floor and the wall: Installation preparation: Clean the dust from the seams and wipe them clean. Apply neutral silicone adhesive to the back of the edge strip.

[0051] Fixing method: Attach the edge strip to the joint, ensuring that the upper surface is flush with the floor tiles. Press it down and temporarily fix it with tape. Remove the tape and clean up any excess adhesive after 24 hours to ensure that the flatness of the floor and unobstructed passage are not affected.

[0052] Example 2: Overall Construction Process and Acceptance (I) Complete construction process 1. Preliminary preparation: On-site measurement → Drawing of construction drawings → Procurement of materials that meet the requirements.

[0053] 2. Substrate preparation: Clean the original ground → Lay the leveling layer → Curing → Apply waterproof layer → Water tightness test → Curing.

[0054] 3. Installation of core components: Modify drainage pipes → Install long, concealed floor drains 4 → Install round filter floor drains 5 → Construct drainage channel components 3 → Verify connectivity.

[0055] 4. Floor decoration: Laying tiles → Grouting → Installing glass partition → Installing edge trim.

[0056] 5. Acceptance: Inspect the flatness of the ground → Test the drainage function → Re-inspect the waterproof performance → Verify unobstructed passage.

[0057] (II) Acceptance Criteria and Verification Methods 1. Ground flatness: Use a straightedge to check, the maximum gap should be ≤2mm; use a level to check the elevation, the deviation should be ≤1mm.

[0058] 2. Drainage function: When water is poured into a dry area, observe the water flow into the long drain along drainage channel A within 30 seconds; when water is poured into a wet area, observe the water flow into the round drain along drainage channels B and C within 1 minute, with no water accumulation on the ground.

[0059] 3. Waterproof performance: Conduct a second water tightness test for 24 hours to confirm no leakage; fill the drainage trough with water and check the trough walls and joints for any water seepage.

[0060] Example 3: Working Principle (Drainage Process) 1. Dry area drainage: Because the drainage trough A is lower than the ground, the water in the dry area flows naturally to the drainage trough A, and converges along the slope of the trough to the concave water inlet hole of the long invisible floor drain 4, and is discharged into the first sewer pipe through the floor drain core.

[0061] 2. Wet area drainage: Part of the shower water in the wet area flows along drainage channels B and C to the circular filter drain 5, and after being filtered by the filter, it is discharged into the second drain pipe; another part of the water near the dry and wet area boundary flows to drainage channel A and is discharged through the long strip concealed drain 4, realizing "shared drainage system for dry and wet areas"; there is no water stagnation throughout the process, and there are no height differences or water-blocking stones on the ground, ensuring safe passage.

[0062] In summary, the dual-point barrier-free drainage floor of this utility model embodiment has the same elevation for the dry area floor 1 and the wet area floor 2, without water-blocking stones or additional slopes, completely eliminating passage obstacles and significantly improving the safety of passage for the elderly, children, and disabled people; the drainage channel component 3 connects the long strip concealed floor drain 4 and the circular filter floor drain 5, realizing the sharing of the drainage system for dry and wet areas, reducing the number of floor drains and pipes to reduce costs, and the multi-directional drainage slope improves the efficiency of water drainage; the cover plate of the long strip concealed floor drain 4 fits the ground material for a visually integrated look, and a wide range of decorative materials can be selected to meet both aesthetic and style requirements; the underlying leveling layer and waterproof layer meet the specifications, preventing water seepage and extending service life.
