TECHNICAL FIELD
[0001] The present application relates to the field of bathroom installation technology, in particular to a bathroom SPC wallboard splicing and fixing structure. BACKGROUND
[0002] With the development of modern building decoration technology, the rapid decoration and waterproof and moisture-proof demand of bathroom space are increasingly prominent. The traditional bathroom board installation generally has the problems of complex on-site cutting construction, low installation efficiency, and easy dust pollution; the sealing performance of the connection between the plane and the corner is insufficient, and leakage is easy to occur after long-term use; special profiles need to be customized for the connection of walls with different angles, and the adaptability is poor; the fixing structure of the board and the ground and the wall surface is unstable and easy to deform; the traditional sealing material is easy to age and fail, and the maintenance cost is high. In addition, the connection structure of the existing chassis and wallboard is usually only connected by simple clamping, and lacks reliable positioning and waterproof protection. CONTENT OF THE UTILITY MODEL
[0003] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a bathroom SPC wallboard splicing and fixing structure, which effectively solves the problems of rapid installation, sealing, waterproofing and complex corner processing in bathroom space by innovative modular frame splicing system, multiple waterproof structure and polygonal corner connection design, and provides an efficient and reliable solution for bathroom decoration.
[0004] The present application is realized by the following technical solutions:
[0005] A bathroom SPC wallboard splicing and fixing structure, comprising an SPC wallboard and a chassis, the SPC wallboard is fixed in a rectangular frame, the rectangular frame is spliced by main profiles, and the outer side of the frame of the rectangular frame is provided with a first connecting groove; two rectangular frames in the same plane are connected by a first clamping piece matched with the first connecting groove; two rectangular frames in different planes are provided with a corner connecting profile, the corner connecting profile comprises a matching surface matched with the rectangular frame, and the surface is provided with a second connecting groove; the second connecting groove is provided with a second clamping piece, the second clamping piece is matched with the first connecting groove, and the second connecting groove and the first connecting groove are connected by the second clamping piece; the first connecting groove is provided with a sealing strip; the edge of the chassis is provided with a groove matched with the second clamping piece, and the first connecting groove of the rectangular frame and the groove are connected by the second clamping piece.
[0006] By adopting the above technical solution, two rectangular frames on the same plane are connected by a first snap-fit fitting that matches the first connecting groove. This snap-fit method can enhance the connection strength of the structure in the planar direction, making adjacent rectangular frames tightly joined together, less prone to relative displacement, and improving the overall stability of the structure in the horizontal direction. A sealing strip is provided in the first connecting groove, which can effectively prevent water in the bathroom from leaking out through the board seam, improving the sealing and protection performance of the structure. Compared with traditional welding, bolt connection and other methods, the installation process is simpler and faster by using snap-fit fittings, reducing construction time and labor intensity. The edge of the chassis is provided with a groove that matches the second snap-fit fitting. The first connecting groove of the rectangular frame and the groove are connected by the second snap-fit fitting, so that the rectangular frame can be quickly and accurately installed on the chassis.
[0007] Optionally, the chassis edge is provided with a waterproof fence; the waterproof fence is located outside the groove.
[0008] By adopting the above technical solution, since the waterproof fence is located outside the groove, it can effectively prevent water leakage after the first barrier sealing strip leaks, and the waterproof fence can effectively play the role of a second waterproof barrier.
[0009] Optionally, the corner connecting profile is a regular polygonal column structure.
[0010] By adopting the above technical solution, multiple sides of the regular polygonal column can be connected to rectangular frames with different design angles as needed, adapting to various complex corner situations in bathroom spaces; when the corner connecting profile of the regular polygonal column structure is connected to the rectangular frame, its multiple sides can fit tightly with the corresponding sides of the rectangular frame. With the help of components such as snap-fit parts and sealing strips, a better sealing effect can be achieved, effectively preventing water from seeping into the corner gaps, avoiding problems such as mold and corrosion caused by leakage, and extending the service life of bathroom facilities.
[0011] Optionally, the side of the corner connecting profile is a mating surface.
[0012] By adopting the above technical solution, the mating surface provides a precise connection interface between the corner connecting profile and the rectangular frame. Since SPC panel splicing requires high precision to ensure the stability and sealing of the overall structure, this specially designed mating surface can precisely match the corresponding parts of the rectangular frame, making the installation process smoother, reducing installation errors, and ensuring that all components are tightly connected and accurately positioned, thereby improving the quality and reliability of the entire splicing and fixing structure. The mating surface also makes the corner connections neater and more aesthetically pleasing.
[0013] Optionally, a retaining plate is provided on the inner wall of the first connecting groove.
[0014] By adopting the above technical solution, the clamp plate can serve as a positioning marker and guide structure during installation. Installers can accurately insert the sealing strip into the first connecting groove based on the clamp plate's position, ensuring accurate insertion depth and location, thus improving installation efficiency and accuracy and reducing adjustments during installation. When the rectangular frame is spliced through the first connecting groove or connected to the chassis, the clamp plate can be embedded in the slot of the first snap-fit component or fit tightly with it, preventing relative sliding or displacement between connecting parts, thereby enhancing the stability of the entire splicing and fixing structure and making the bathroom SPC wall panel more robust and reliable during use.
[0015] Optionally, the sealing strip is provided with a snap-fit part that is adapted to the card plate.
[0016] By adopting the above technical solution, the snap-fit part and the clamping plate fit tightly together, ensuring the sealing strip is more securely fixed in the first connecting groove during installation, preventing displacement or detachment. During installation, the fit between the snap-fit part and the clamping plate provides clear installation guidance for installers. Installers can accurately snap the snap-fit part of the sealing strip into the clamping plate, quickly positioning and installing the sealing strip, improving installation efficiency and reducing installation time and costs. Simultaneously, this accurate positioning also helps ensure the installation precision of each component, making the entire splicing structure more regular.
[0017] Optionally, the first snap-fit component is provided with a snap-fit groove that is adapted to the snap-fit plate.
[0018] By adopting the above technical solution, the snap-fit groove and the snap-fit plate are compatible, providing precise positioning for the first snap-fit component and the first connecting groove. During installation, the snap-fit plate is embedded in the snap-fit groove, allowing the first snap-fit component to be accurately installed in the predetermined position, ensuring the accuracy of the splicing and helping to maintain the regularity of the entire wall panel splicing and fixing structure. This compatible snap-fit design allows for simple and convenient connection during installation; simply align the snap-fit plate with the snap-fit groove and insert it to complete the connection, improving installation efficiency.
[0019] Optionally, the rectangular frame has an arc-shaped portion on the surface where it connects to the SPC wall panel.
[0020] By adopting the above technical solution, the curved part can increase the surface area of the main profile under stress, and better embed it with the SPC wall panel, so that the SPC wall panel is not easy to shake during use.
[0021] Optionally, the upper end of the rectangular frame is connected to the wall panel via corner brackets.
[0022] By adopting the above technical solution, the corner bracket, as an intermediate connecting component, can effectively and tightly connect the rectangular frame and the wall panel, making the entire structure a stable whole. In a bathroom environment, it can resist external forces such as water flow impact and object collision, preventing the rectangular frame from separating or shifting from the wall panel due to external forces, ensuring the stability of the wall panel structure, and guaranteeing the normal use of bathroom facilities. Using corner brackets to connect the rectangular frame and the wall panel makes the installation process relatively simple; construction workers can quickly complete the installation using bolts, screws, and other connectors. In later maintenance or component replacement, the corner brackets can also be easily disassembled for repair or replacement of the corresponding components, reducing construction difficulty and maintenance costs.
[0023] Optionally, the chassis comprises, from top to bottom, a ceramic tile layer, a PU polyurethane adhesive layer, and a calcium silicate board layer.
[0024] By adopting the above technical solutions, the calcium silicate board layer serves as the base layer, providing high rigidity, moisture resistance, and fire resistance, ensuring the load-bearing capacity of the wall and preventing deformation; the PU polyurethane adhesive layer can bond the ceramic tile to the calcium silicate board, buffering stress and reducing the risk of cracking caused by thermal expansion and contraction; the calcium silicate board is corrosion-resistant, and the PU polyurethane adhesive is anti-aging, extending its service life; the ceramic tile surface is easy to clean.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. This application achieves a tight connection between adjacent rectangular frames through the matching design of the first snap-fit component and the first connecting groove, reducing the relative displacement in the horizontal direction and improving the stability of the overall structure; the cooperation between the chassis groove and the second snap-fit component ensures that the rectangular frame is installed in an accurate position, avoids misalignment, and further strengthens the integrity of the structure.
[0027] 2. This application utilizes a sealing strip to fill the gap between the first connecting groove and other connecting components, achieving a sealing effect and preventing water from penetrating into the interior of the wall panel. This avoids problems such as wall panel damage and mold caused by dampness, improves the waterproof performance of the bathroom space, and extends the service life of the wall panel and the entire structure. Furthermore, the waterproof barrier can block the outflow of bath water and floor water, preventing water leakage into areas outside the bathroom space, further improving the waterproof performance of the bathroom space and protecting the surrounding environment from water erosion. It has a double waterproof structure.
[0028] 3. In this application, the groove provides installation space for the second snap-fit component. The first connecting groove of the rectangular frame is connected to the groove of the chassis through the second snap-fit component, which realizes a stable connection between the wall panel and the chassis, making the entire bathroom structure more stable. It also facilitates installation and positioning. This allows the wall panel and the chassis to form an integral structure, enhancing the stability of the entire bathroom facility, and also facilitating installation and improving construction efficiency.
