Description

Technical Field

[0001] The utility model relates to the technical field of bathroom waterproof facilities, in particular to a bathroom waterproof chassis. Background Art

[0002] In residential buildings, a key aspect of bathroom or toilet design is waterproofing. Since these areas are frequently exposed to water, waterproofing is essential to protect the integrity of the building structure. If not properly treated, moisture may penetrate through the floor or walls, which may cause structural damage in the long term and increase the risk of mold growth, which in turn affects the health and safety of occupants.

[0003] To address this problem, waterproof pans are often installed in bathrooms and toilets. These pans are designed to capture and direct water flow, ensuring that water does not escape a specific area, thereby preventing leakage and subsequent possible water damage. Traditional waterproof pans usually require the use of molds for production, which is a long production cycle and high cost. In addition, once the pan is produced, it is difficult to flexibly modify it if the size needs to be adjusted on site, which severely limits its customizability.

[0004] For example, a popular waterproof chassis in the market is SMC (Sheet Molding Compound) waterproof chassis. This chassis originated in Japan and is an integrated product produced by high-cost molds. Although they have good waterproof effects, they require expensive molds during the production process, which leads to extremely high production costs. Moreover, for personalized needs that require specific sizes, this type of product is difficult to meet the market.

[0005] Another type of waterproof chassis on the market is a product that uses thermoplastic materials through vacuum forming. Although this type of chassis has lower production costs than SMC chassis, it still requires mold costs ranging from thousands to tens of thousands of yuan. In addition, the strength of thermoplastic materials is usually not enough to withstand human trampling, so it can only serve as a waterproof layer, and after installation, a layer of cement mortar needs to be applied on its surface and tiles need to be affixed to meet the use requirements, which not only increases the complexity of installation, but also prolongs the time of the entire installation process.

[0006] In general, the existing waterproof chassis technology has problems such as limited application scope, long production cycle, high cost and poor customizability, which restrict its popularity and application in the market.

[0007] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 5 As shown, the design of the bathroom waterproof chassis of the utility model not only takes into account the ease of installation, structural strength, and economic cost, but also takes into account the personalized needs of users, so that it can be customized according to the size and shape of different bathroom spaces.

[0031] The main structure of the waterproof chassis includes a bottom plate 1, which is the basis of the waterproof chassis. The bottom plate 1 is a glass fiber reinforced plastic honeycomb panel, specifically composed of a first flat plate layer 11, a honeycomb honeycomb layer 12 and a second flat plate layer 13, wherein each layer is bonded and fixed by a composite glue 14 and is composited by high pressure. The glass fiber reinforced plastic honeycomb panel selected for the bottom plate 1 ensures the lightness and high strength of the product. This structure not only ensures the overall stability, but also provides excellent waterproof properties and high durability due to the material of the glass fiber reinforced plastic.

[0032] More specifically, the first flat plate layer 11 and the second flat plate layer 13 are both glass fiber reinforced plastic plates formed by pultrusion of glass fiber and resin, and the honeycomb plate layer 12 is a polypropylene honeycomb plate.

[0033] Among them, GFRP, glass fiber reinforced plastic, also known as glass fiber resin, is a material composed of glass fiber and resin. The "glass fiber" here provides reinforcement, while the "resin" acts as a binder, allowing the glass fiber to remain in a specific shape and position and provide environmental protection.

[0034] Glass fiber is a material made of extremely fine glass filaments, which has very high tensile strength, good insulation, high temperature resistance, chemical corrosion resistance, etc. Common types of resins include plastic matrices such as polyester resin, vinyl resin and epoxy resin.

[0035] The composite adhesive 14 is usually an adhesive for bonding different materials or the same materials, and it can be a single-component or multi-component system. Common composite adhesives 14 include epoxy composite adhesives, polyurethane composite adhesives, acrylic composite adhesives, silicone composite adhesives, hot-melt composite adhesives, and the like.

[0036] Two inner and outer L-shaped frames, i.e., an inner frame 2 and an outer frame 3, are installed around the base plate 1. The first flat layer 11 and the second flat layer 13 are both glass fiber reinforced plastic sheets formed by pultrusion of glass fiber and resin. In other words, the two frames are made of glass fiber reinforced plastic profiles, providing strong support and good waterproof properties. The inner frame 2 includes a first vertical plate 21 and a first horizontal plate 22, while the outer frame 3 includes a second vertical plate 31 and a second horizontal plate 32. The two horizontal plates are respectively attached to the upper and lower surfaces of the base plate 1, and the two vertical plates are attached to each other and fixed by fasteners 4 (which can be screws or rivets) to ensure the stability of the structure.

[0037] The inner frame 2 and the outer frame 3 are covered with a specially designed waterproof felt layer 5, which plays a vital role. It not only provides additional protection for the inner and outer frames, but more importantly, it completely encloses the inner frame 2, the outer frame 3 and the fasteners 4 to form a continuous and seamless waterproof barrier.

[0038] In detail, the periphery of the entire chassis 1, including the inner frame 2, the outer frame 3 and the fasteners 4, is surrounded by a waterproof felt layer 5, that is, a glass fiber resin layer (or fiberglass reinforced plastic layer), to provide additional sealing and waterproof protection. This waterproof felt layer 5 (glass fiber resin layer) is made of a composite of glass fiber and resin, which not only enhances the overall waterproof effect, but also provides additional structural strength for the chassis.

[0039] This waterproof mat layer 5 can adapt to different shapes of frames and prevent moisture from penetrating through any tiny gaps. The waterproof mat layer 5 is precisely shaped during the construction process to ensure that it can perfectly fit the contours of the inner and outer frames while covering the fasteners 4. The edges of the waterproof mat layer 5 form a solid bond with the upper and lower surfaces of the base plate 1. This sealed connection not only improves the waterproof effect of the entire chassis structure, but also enhances the integrity of the structure and ensures durability in long-term use.

[0040] In order to further improve the practicality of the chassis, especially the performance in drainage, the utility model adds pads 6, which are placed below the edge of the lower surface of the bottom plate 1 to raise the side of the bottom plate 1 and make the bottom plate 1 tilted. By using pads 6 of different heights, a drainage slope can be effectively formed, which prompts water to flow to the designated drainage position, thereby avoiding water accumulation on the surface of the chassis and ensuring the dryness and cleanliness of the bathroom floor.

[0041] The design of the pads 6 takes into account the waterproof requirements of the entire chassis, so these pads are also covered by the waterproof felt layer 5. The waterproof felt layer 5 wraps each pad to form an additional waterproof barrier. This layer of coverage ensures that even the tiny gap between the pads 6 and the bottom plate 1 will not become a channel for water to penetrate, providing all-round waterproof protection for the entire chassis 1.

[0042] The production process of this design is simple and clear, divided into the following steps:

[0043] Step S1: prefabricate a base plate 1, an inner frame 2, an outer frame 3 and a cushion block 6.

[0044] Step S2: According to the specific size of the bathroom, the base plate 1, the inner frame 2, and the outer frame 3 are cut to a suitable size.

[0045] Step S3: Place the base plate 1 and install the outer frame 3 around its periphery, and place the pads 6 to form the required drainage slope.

[0046] Step S4: Install the inner frame 2 so that the first transverse plate 22 is in contact with the edge of the upper surface of the bottom plate 1 , and ensure that the first vertical plate 21 is in contact with the second vertical plate 31 of the outer frame 3 .

[0047] Step S5: drilling holes at corresponding positions of the inner and outer frames, and inserting fasteners 4 for fixing.

[0048] Step S6: Use glass fiber to cover the inner and outer frames, fasteners 4 and pads 6, and apply resin, which is then allowed to dry and solidify to form a waterproof carpet layer 5.

[0049] The waterproof chassis of this utility model adopts an innovative design concept. By combining the fiberglass profile frame and the fiberglass honeycomb bottom plate, a strong and light waterproof chassis structure is formed. In the splicing process, the gap between the bottom plate and the frame is filled and sealed by using fiberglass resin as an adhesive and waterproof coating layer, and finally secondary molding is achieved. This method greatly improves the overall waterproof performance of the waterproof chassis. This design not only ensures the stability and sealing of the structure, but also has the following significant advantages:

[0050] 1) High degree of customization: A highlight of this utility model is its high degree of customization. Since it does not rely on prefabricated molds, the waterproof chassis can be customized on site according to actual needs. Whether it is cutting or adding, it can be flexibly adjusted according to space requirements and customer preferences. This customization method provides great convenience for users and is especially suitable for various special designs and needs.

[0051] 2) Simple manufacturing process: The base plate, inner and outer frames of the utility model have simple structures, and the splicing method is intuitive and easy to operate. Finally, the waterproof felt layer is used for packaging and protection. The entire manufacturing process is neither complicated nor time-consuming. Such a design not only reduces the burden on construction workers, but also significantly shortens the installation period and improves efficiency.

[0052] 3) Excellent physical properties: The lightweight, corrosion-resistant and high-strength fiberglass material is selected, so that the waterproof chassis of the utility model has excellent structural strength and durability while maintaining its lightness. These characteristics of fiberglass ensure that the waterproof chassis can withstand various pressures and impacts in daily use for a long time without being easily damaged.

[0053] 4) Cost-effectiveness: FRP materials not only have outstanding performance, but also relatively low cost, which means that the waterproof chassis of this utility model can greatly reduce the cost of production and sales while ensuring high quality. This feature makes it a highly cost-effective choice in the market, providing consumers with an economical and affordable solution.
