Description

Technical Field

[0001] The utility model relates to the technical field of toilet assembled chassis, in particular to a barrier-free toilet assembled chassis system. Background Art

[0002] Prefabricated system bathrooms are a new type of prefabricated dry-process renovation, different from traditional bathroom renovations. Common chassis on the market include FRP integrated chassis, SMC molded chassis, and polyurethane composite foam chassis. These chassis are manufactured in a standardized, industrialized factory and then installed in the bathroom using a dry-process assembly method. Compared to traditional wet-process bathrooms, these systems offer shorter construction times, higher efficiency, more reliable quality, lighter weight, quieter construction, improved health and environmental friendliness, simpler installation, and lower technical requirements for construction personnel.

[0003] The FRP integrated chassis is an integrated chassis structure that is manually manufactured using fiber reinforced composite materials (FRP). The SMC molded chassis is a chassis structure that is made using sheet molding compound (SMC) through a molding process. The polyurethane composite foam chassis is a chassis structure that is made using polyurethane materials through a composite foaming process.

[0004] FRP integrated chassis are manufactured by hand, a complex process that places high demands on production equipment and molds. These processes require specialized technicians, resulting in high manufacturing costs. FRP integrated chassis production involves multiple steps, including mold design, material preparation, molding, and curing. Each step requires strict control and operation, otherwise quality issues are likely to occur. SMC molded chassis are typically produced using molds, which are complex to design and manufacture. Large, high-precision, or complex chassis molds are expensive to produce. Their production requires large, fixed molds and fixed-tonnage presses, resulting in high initial investment costs and limited flexibility, making it difficult to meet the diverse needs of domestic housing types. Polyurethane composite foam chassis are formed by combining ceramic tiles with polyurethane foam. The foaming process is prone to producing irritating gases. Furthermore, polyurethane foam is not suitable for long-term submersion in water, as its numerous internal pores can easily become breeding grounds for bacteria, mold, and other microorganisms. Their production also relies on large molds and equipment, requiring custom molds, multiple steps, and complex processes, resulting in high investment costs.

[0005] The above three types of chassis generally have a relatively high thickness due to product strength requirements and production process requirements. In existing buildings or renovation projects, bathrooms constructed with these three types of chassis will exceed the outdoor height and form steps, which are easy to trip and not conducive to daily use, posing serious risks.

[0006] Because they are complete sets of assemblies, the above three types of chassis need to be made much smaller than the indoor space in order to be installed. During decoration, they will take up a large amount of bathroom space, wasting space and affecting the user experience. In addition, in existing buildings or renovation projects, the original drainage pipes are at risk of aging or leakage. The above three types of chassis can only use the inherent drainage system in the bathroom. In the scenario of drainage requirements on the same floor, the height of the threshold is even more worrying. The threshold height is above 220mm, which is extremely unfriendly to users.

[0007] When the above three types of chassis meet the needs of large space scenes, they can only be assembled on-site in a block-by-block manner. The joints between the chassis are decorated with water retaining strips for transition. The height is above 60mm, which is extremely unfriendly to users, especially the elderly, and poses serious risks.

[0008] Therefore, the present application proposes an assembled chassis system for a barrier-free toilet. Utility Model Content

[0012] Wherein, the overhead layer board and the hardened layer board are both polymer board structures, and the waterproof layer board is a nano-coating board structure.

[0013] Preferably, the leveler includes a base and an upper cover, the base is fixedly mounted on the civil floor, the upper cover is threadedly mounted on the base, and the top of the upper cover contacts the bottom of the overhead floor.

[0014] Preferably, the water receiving tray is arranged on the waterproof layer plate and is sealed and fixed between the waterproof layer plate, the top surface of the water receiving tray is flush with the top surface of the hardened layer plate, the floor drain is clamped on the water receiving tray, the water seal bottom box is arranged under the waterproof layer plate and is sealed and fixed between the waterproof layer plate, and a water seal cavity is further provided in the water seal bottom box, and the water seal cavity and the water receiving tray form a water seal structure;

[0015] The drainage pipe comprises a first connecting pipe, one end of which is communicated with the interior of the water seal bottom box, and the other end of which is communicated with the indoor riser.

[0016] Preferably, the drainage pipe further includes a second connecting pipe, one end of which is connected to the water outlet of the basin, and the other end of which is connected to the indoor riser.

[0017] Preferably, the floor drain divides the entire bathroom into two areas, a dry area and a wet area, wherein the overhead layer, the waterproof layer and the hardened layer in the wet area are arranged as a whole piece, and the overhead layer, the waterproof layer and the hardened layer in the dry area are arranged as multiple pieces that are split and spliced.

[0018] Preferably, the edge of the waterproof layer plate is provided with an anti-edge.

[0019] Preferably, the base layer of the nano-coated board is a polystyrene board, and a glass fiber mesh structure is laid on the outer surface of the polystyrene board and then a nano-coating is attached for waterproof reinforcement.

[0020] Preferably, the waterproof layer and the hardened layer within the wet area have drainage slopes.

[0021] Preferably, the overhead layer is composed of at least two polymer plates;

[0022] The waterproof layer plate is sealed by at least two nano-coated plates joined in a mortise and tenon manner, and the joint of the nano-coated plates is staggered with the joint of the polymer plate below;

[0023] The hardened layer plate is composed of at least two high molecular polymer plates, and the junction of the high molecular polymer plates is staggered with the junction of the nano coating plate below.

[0024] The utility model has at least the following beneficial effects:

[0025] 1. Flexibility: One case for each household, no mold production is required to meet the needs of various household types. The three types of chassis, FRP integrated chassis, SMC molded chassis and polyurethane composite foam chassis, cannot quickly meet the needs of multiple households because they require mold production. The X5 water shield chassis meets diverse size requirements, does not require molds, and can quickly respond to user needs. The X5 water shield chassis does not require molds and can be produced directly, greatly shortening the production cycle. Changes in user needs are often unpredictable. Companies need to be able to flexibly adjust production plans to adapt to changes. Flexible production does not require molds, making it easier to adjust production plans. Production lines can be adjusted in time according to changes in market demand to produce products of different sizes.

[0026] 2. Anti-leakage: The waterproof layer adopts honeycomb closed mold production, which is a closed-cell honeycomb structure formed by continuous extrusion. This structure makes the pores inside the board independent and closed, with almost no connected gaps. It is difficult for water molecules to enter the interior of the board through these tiny, closed pores, thereby effectively preventing the penetration of water.

[0027] 3. Low cost: Dry assembly is used, and mold manufacturing is not required. In the product production process, mold manufacturing is often a huge expense. Different products may require molds of different specifications and shapes, and the design, manufacturing and maintenance costs of molds are very high. Dry assembly does not require mold manufacturing, which directly saves this huge expense. There is no mold manufacturing production requirement, which improves production efficiency and reduces indirect costs.

[0028] 4. Easy to process: It can be processed with a utility knife. The production tools are simple and easy to obtain, which greatly improves the convenience of processing. There is no need to purchase special large or dedicated processing equipment, which reduces the threshold and cost of processing. The use of the utility knife is relatively simple, and even people without professional processing experience can quickly get started. This allows ordinary people to easily participate in the material processing process and realize their own creativity and design.

[0029] 5. Large-area construction: Modular on-site assembly can be carried out in different areas. Modular on-site assembly can reduce on-site operation time and greatly reduce the complex on-site construction procedures. Most modules have been pre-fabricated in the factory, and the quality is better controlled. Only simple assembly work is required on-site, which greatly reduces the difficulty and time cost of on-site construction.

[0030] 6. Easy to carry: Lightweight, easy to carry and transport vertically. The modularization of the chassis reduces the labor intensity of the operation, increases the operational flexibility, reduces the transportation cost, and improves the transportation efficiency.

[0031] 7. Tongue and groove overlap and gluing method: The waterproof layer adopts a staggered mortise and tenon structure design. The mortise and tenon structure is cleverly designed to allow the components to fit together to form a firm connection. This connection method can effectively disperse stress and improve the overall stability of the structure. The staggered design makes the connection between the structural layers tighter, reducing the possibility of moisture penetration. When the structural layers are overlapped with a staggered mortise and tenon structure, it is difficult for moisture to enter the interior through the connection, thereby improving the overall waterproof performance. The installed waterproof layer has many advantages such as high stability, high waterproof performance, easy installation, and durability.

[0032] 8. Low load: The X5 Water Shield chassis structure is made of lightweight new materials, which are light in weight and high in strength. The use of lightweight new materials greatly reduces the weight of the X5 Water Shield chassis, thereby reducing the load-bearing requirements of the building structure, which can effectively reduce the investment in foundation engineering and reduce the difficulty and cost of foundation treatment. For renovation projects of existing buildings, the low-load chassis can reduce the need for reinforcement of the original structure, reduce renovation costs and construction difficulty. For example, in the roof renovation of old buildings, the use of a chassis made of lightweight materials can avoid excessive burden on the original roof structure.

[0033] 9. Low level: chassis and drainage are designed as a whole, and drainage is embedded in the chassis to effectively reduce the overall height.

[0034] 10. Barrier-free design: The low threshold makes it easier for people to enter and exit the bathroom. Whether it is a child or a person with mobility difficulties, they can easily cross the low threshold, reducing the obstacles and inconvenience caused by the high threshold, ensuring that these people can enter and exit the bathroom independently and safely, improving their quality of life and ability to participate in social activities. The barrier-free design reduces the risk of tripping and ensures personal safety. The low threshold gives people a simple and smooth visual experience. It does not appear abrupt and bulky like a high threshold, but blends with the ground to make the entire space more beautiful and harmonious. The low threshold can make the transition between different spaces more natural and enhance the continuity and openness of the space. It does not visually divide the space like a high threshold, but makes people feel that the space is more spacious and transparent.

[0035] 11. Deodorization and water leakage prevention: Old pipe systems are prone to accumulate dirt, bacteria and debris during long-term use. These substances will produce unpleasant odors. This odor will not only affect the indoor air quality, but may also have adverse effects on human health, such as causing respiratory discomfort, nausea and other symptoms. The new pipe system can fundamentally eliminate the generation of odors and create a fresh and comfortable bathroom environment for users. The new pipe system uses high-quality materials and advanced connection technology, and has better pressure resistance, corrosion resistance and wear resistance. These characteristics enable the pipe system to maintain stable performance during long-term use, reduce the frequency of repairs and replacements, and reduce maintenance costs.

[0046] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0047] Please refer to Figures 1 to 7As shown, in an embodiment of the present invention, an assembled chassis system for an accessible toilet includes: a supporting component, the supporting component includes a plurality of levelers 2 installed on a civil floor 1 in the toilet, and a chassis structure group 3 is installed on the leveler 2; a drainage component, the drainage component includes a floor drain 4, a water collecting pan 5, a water seal bottom box 6 and drainage pipe fittings, the floor drain 4, the water collecting pan 5 and the water seal bottom box 6 are all installed on the chassis structure group 3, and the drainage pipe fittings are respectively connected to the indoor riser 7 and the water seal bottom box 6. The supporting components and drainage components of the assembled chassis system of the accessible toilet cooperate with each other to provide stable support and efficient drainage function for the accessible toilet.

[0048] Furthermore, the chassis structure group 3 includes an overhead layer 301, a waterproof layer 302 and a hardened layer 303. The overhead layer 301 is installed on the upper part of the leveler 2, the waterproof layer 302 is installed on the top of the overhead layer 301, and the hardened layer 303 is installed on the top of the waterproof layer 302. The overhead layer 301, the waterproof layer 302 and the hardened layer 303 are laid and installed in layers; wherein the overhead layer 301 and the hardened layer 303 are both polymer plate structures, the waterproof layer 302 is a nano-coated plate structure, and the overhead layer 301 is installed on the upper part of the leveler 2. , providing a stable supporting foundation for the entire chassis structure. Through the overhead design, it is convenient to lay and maintain various types of pipes underneath, avoiding the difficulties of pipe installation and maintenance in the traditional bathroom floor laying method. It adopts a high molecular polymer board structure with the characteristics of light weight, high strength and corrosion resistance. While ensuring structural stability, it will not add excessive load to the building. The waterproof layer board 302 is located between the overhead layer board 301 and the hardened layer board, playing a key waterproof role. The nano-coated board structure makes it have excellent waterproof performance and can effectively prevent water seepage in the bathroom. The nano-coating technology can form a dense waterproof film on the surface of the board to prevent the penetration of water molecules, and it also has good corrosion resistance and wear resistance, and can maintain the waterproof effect for a long time. The hardened layer 303 is installed on the top of the waterproof layer 302 to provide users with a solid walking surface. The hardened layer of the polymer board structure has high hardness and strength, can withstand the weight of the human body and various pressures of daily use, is not easy to deform and damage, and can effectively protect the waterproof layer 302 and the overhead layer 301. To extend the service life of the entire chassis structure, the overhead layer 301, waterproof layer 302 and hardened layer 303 are laid and installed in layers, each performing its own function, and together constitute a complete and powerful chassis structure. This layered design allows each functional layer to play its maximum role, and also facilitates targeted repair and replacement when problems arise. In addition, the overhead layer 301 and hardened layer 303 of the polymer board structure have good plasticity and processing performance, and can be customized according to different bathroom shapes and sizes to adapt to various complex installation environments.

[0049] Furthermore, the leveler 2 includes a base 201 and an upper cover 202. The base 201 is fixedly mounted on the civil floor 1, and the upper cover 202 is threadedly mounted on the base 201. The top of the upper cover 202 contacts the bottom of the overhead shelf 301. By threading the upper cover 202 on the base 201, this connection method facilitates height adjustment. By rotating the upper cover 202, the height of the upper cover 202 relative to the base 201 can be changed, thereby achieving horizontal adjustment of the overhead shelf 301 above. The threaded connection has a certain degree of precision and stability, which can ensure that the height change during the adjustment process is uniform and controllable. By adjusting the height of the upper cover 202, the overhead shelf 301 can be in a horizontal state, ensuring the stability of the entire chassis structure and comfort of use.

[0050] Furthermore, the water receiving tray 5 is arranged on the waterproof layer plate 302 and is sealed and fixed between the waterproof layer plate 302. The top surface of the water receiving tray 5 is flush with the top surface of the hardened layer plate 303. The floor drain 4 is clamped on the water receiving tray 5. The water seal bottom box 6 is arranged under the waterproof layer plate 302 and is sealed and fixed between the waterproof layer plate 302. A water seal cavity is also provided in the water seal bottom box 6. The water seal cavity and the water receiving tray 5 form a water seal structure; the drainage pipe fitting includes a first connecting pipe 8, one end of the first connecting pipe 8 is connected to the inside of the water seal bottom box 6, and the other end is connected to the indoor riser 7. The water receiving tray 5 is arranged on the waterproof layer plate 302 and is sealed and fixed between the waterproof layer plate 302. This installation method ensures that there will be no water leakage between the water receiving tray 5 and the waterproof layer plate 302. It effectively prevents water from penetrating into the lower structure. The top surface of the water receiving tray 5 is flush with the top surface of the hardened layer plate 303, making the entire bathroom floor more flat in appearance without any height difference, which is convenient for users to walk and for equipment such as wheelchairs to pass through. The floor drain 4 is snapped onto the water receiving tray 5. This connection method is simple and fast, and is easy to install and disassemble. The snap-in connection can be achieved by cooperating between the bayonet on the floor drain 4 and the card groove on the water receiving tray 5 to ensure that the connection between the floor drain 4 and the water receiving tray 5 is firm and reliable. The water seal bottom box 6 is set under the waterproof layer plate 302 and sealed and fixed between the waterproof layer plate 302, which can effectively prevent water from penetrating to ensure the sealing of the entire drainage system. The first connecting pipe 8 serves to transport the water in the water seal bottom box 6 to the inside of the indoor riser 7.

[0051] Furthermore, the drainage pipe also includes a second connecting pipe 9, one end of which is connected to the water outlet of the basin, and the other end is connected to the indoor riser 7. The second connecting pipe 9 plays an important role in connecting the basin drainage and the indoor riser 7 in the drainage system of the barrier-free toilet assembled chassis system, so that the drainage of the basin and the drainage of other parts of the toilet are independent of each other but unified in the entire drainage system, thereby improving the efficiency and reliability of drainage, and further improving the practicality of the barrier-free toilet assembled chassis system.

[0052] Furthermore, the floor drain 4 divides the entire bathroom into two areas, a dry area 10 and a wet area 11, wherein the overhead layer 301, the waterproof layer 302 and the hardened layer 303 in the wet area 11 are set as a whole block, and the overhead layer 301, the waterproof layer 302 and the hardened layer 303 in the dry area 10 are set as multiple pieces divided and spliced. The floor drain 4 plays an important role in dividing the areas in the bathroom. This division helps to clarify the functions of different areas and improve the efficiency and comfort of the bathroom. By setting the overhead layer 301, the waterproof layer 302 and the hardened layer 303 in the wet area 11 as a whole block, this design can enhance the structural stability and waterproof performance of the wet area 11, and can It can better withstand the impact of accumulated water and water flow that may occur in the wet area 11, reduce the joints between the boards, and reduce the risk of water leakage. At the same time, the installation of the entire board is relatively simple, which can improve construction efficiency. The overhead layer 301, waterproof layer 302 and hardened layer 303 in the dry area 10 are divided and spliced ​​into multiple pieces. This design takes into account the use requirements and installation convenience of the dry area 10. The multi-piece split splicing method can better adapt to the different shapes and sizes of the dry area 10, and is convenient for layout adjustment and maintenance and replacement. In addition, due to the relative dryness, the requirements for the waterproof performance of the board are relatively low, and the multi-piece split splicing method can also meet this requirement while reducing costs.

[0053] Furthermore, the edge of the waterproof layer plate 302 is provided with a reverse edge. By providing the reverse edge, the waterproof performance of the waterproof layer plate 302 can be enhanced. When water flows on the bathroom floor, the reverse edge can play a role in blocking and diverting water, preventing water from penetrating from the edge of the waterproof layer plate 302 to the lower structure, thereby improving the reliability of the bathroom waterproof system.

[0054] Furthermore, the base layer of the nano-coated board is a polystyrene board, and a glass fiber mesh structure is laid on the outer surface of the polystyrene board and then attached with a nano-coating for waterproof reinforcement. The glass fiber mesh laid on the outer surface of the polystyrene board can significantly enhance the overall structural strength of the nano-coated board. The glass fiber mesh has high tensile strength and toughness, and can effectively prevent the polystyrene board from breaking or deforming when subjected to external forces, and can improve the durability of the waterproof layer board 302. The nano-coating is attached to the glass fiber mesh and the surface of the polystyrene board to form a dense waterproof film. Nano-scale particles can fill the tiny pores on the surface of the material and prevent the penetration of water molecules, thereby achieving excellent waterproof effect. In addition, it can also reinforce and protect the polystyrene board and the glass fiber mesh. It can improve the corrosion resistance, wear resistance and aging resistance of the material, and extend the service life of the waterproof layer board.

[0055] Furthermore, the waterproof layer board 302 and the hardened layer board 303 within the wet area 11 have drainage slopes. The waterproof layer board 302 and the hardened layer board 303 have drainage slopes to ensure that water can flow quickly to drainage outlets such as floor drains to avoid the occurrence of water accumulation. In addition, the drainage slope can allow water to be discharged smoothly under the action of gravity, reducing the residence time of water on the surface of the board, thereby reducing the risk of water penetrating into the underlying structure.

[0056] Furthermore, the overhead layer 301 is composed of at least two polymer plates;

[0057] The waterproof layer plate 302 is formed by at least two nano-coated plates sealed by mortise and tenon joints, and the joint of the nano-coated plates is staggered with the joint of the polymer plate below;

[0058] The hardened layer 303 is composed of at least two polymer plates. The joint of the polymer plates is staggered with the joint of the nano-coating plate below. The overhead layer 301 is composed of at least two polymer plates, which can increase the strength and stability of the overhead layer 301. The waterproof layer 302 is composed of at least two nano-coating plates sealed in a mortise and tenon manner. The mortise and tenon structure can provide a tight connection, ensure the sealing between the nano-coating plates, and effectively prevent water penetration. The nano-coating itself has good waterproof performance, and the sealing effect of the mortise and tenon combination effectively improves the waterproof effect of the waterproof layer 302 and increases the overall strength and durability of the waterproof layer. In addition, the nano-coating plate joint The staggered setting of the joint with the lower polymer plate can avoid the joint of multiple layers of boards at the same position, thereby reducing the potential risk of water leakage. The hardened layer 303 is composed of at least two polymer plates. Similar to the overhead layer 301, the combination of multiple plates can increase the strength and hardness of the hardened layer, providing users with a more solid walking surface. The characteristics of the polymer plate make the hardened layer have good wear resistance and impact resistance, and can withstand the wear and impact in daily use. The staggered setting of the joint of the polymer plate and the joint of the nano-coated plate below can avoid overlapping of the joints, reduce the risk of water leakage, and at the same time disperse stress to improve the stability and durability of the plate.

[0059] The working principle of this utility model is:

[0060] When the leveler 2 is in use, the base 201 is fixed on the civil floor 1 to provide a stable basic support. The upper cover 202 is threadedly mounted on the base 201. The height of the upper cover 202 can be adjusted by rotating it. The top of the upper cover 202 contacts the bottom of the overhead floor 301. Since the civil floor 1 may have unevenness, the leveler 2 can adjust the height according to the actual situation to make the overhead floor 301 in a horizontal state, thereby ensuring the stability of the entire chassis structure.

[0061] The use of the floor drain 4 divides the bathroom into a dry area 10 and a wet area 11. The overhead layer 301, waterproof layer 302 and hardened layer 303 of the wet area 11 are set as a whole piece to better withstand the impact of water flow;

[0062] When the water tray 5 is in use, when water falls on the ground, the water tray 5 quickly collects the water and guides it to the floor drain 4. The top surface of the water tray 5 is flush with the top surface of the hardened layer 303 to ensure that the ground is flat.

[0063] When the water seal bottom box 6 is in use, there is a water seal cavity inside, which forms a water seal structure with the water seal cavity to prevent odor and harmful gases in the indoor riser 7 from entering the bathroom through the floor drain;

[0064] The first connecting pipe 8 is used to transport the water in the water seal bottom box 6 to the indoor riser 7, thereby discharging the sewage from the bathroom;

[0065] The second connecting pipe 9 is used to lead the drainage of the basin into the indoor riser 7;

[0066] The base layer of the waterproof layer plate 302 is a polystyrene board with certain thermal insulation performance. The outer surface of the polystyrene board is paved with a glass fiber mesh structure to enhance the structural strength and prevent the board from cracking or deforming. A nano-coating is attached to the surface of the glass fiber mesh. The nano-coating forms a dense waterproof film to prevent water molecules from penetrating. At the same time, it reinforces and protects the polystyrene board and the glass fiber mesh, improving the corrosion resistance, wear resistance and aging resistance of the material. The waterproof layer plate 302 is sealed by at least two nano-coated plates in a mortise and tenon manner to ensure a tight connection and prevent water from penetrating from the connection. The junction of the nano-coated plates is staggered with the junction of the lower polymer plate to avoid the junction of multiple layers of plates at the same position, reducing the potential risk of water leakage, and at the same time dispersing stress to improve the stability and durability of the board. The waterproof layer plate 302 and the hardened layer plate 303 have a drainage slope, so that water can flow quickly to drainage outlets such as floor drains, avoiding the occurrence of water accumulation and reducing the risk of water penetrating into the lower structure.

[0067] The hardened layer 303 is composed of at least two polymer plates, providing users with a solid walking surface that can withstand the weight of the human body and various pressures of daily use and is not easily deformed or damaged. The joints between the polymer plates and the nano-coated plates below are staggered, which also reduces the risk of water leakage and disperses stress.
