Description

Technical Field

[0001] This utility model relates to the field of prefabricated waterproofing technology, and in particular to a prefabricated waterproofing system. Background Technology

[0002] With the development of the construction industry, prefabricated buildings have gradually become an important development direction in the construction field due to their advantages such as fast construction speed, controllable quality, and environmental protection and energy saving. In prefabricated buildings, waterproof structures are required in areas such as indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls, which are areas prone to water exposure, making their waterproof performance particularly important.

[0003] Traditional waterproofing construction mainly uses on-site wet work methods, which rely on the skill level of the workers. When the base layer is uneven, it is not easy to control the thickness and uniformity of the waterproofing material, which can easily lead to uneven laying of the surface material, resulting in poor waterproofing effect of prefabricated building structures. Utility Model Content

[0004] The main purpose of this utility model is to propose a prefabricated waterproofing system, which aims to improve the waterproofing effect in prefabricated building structures where waterproofing structures are required, such as indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls.

[0005] To achieve the above objectives, the present invention proposes a prefabricated waterproofing system, comprising:

[0006] The mounting base has a mounting surface on its surface.

[0007] An internal waterproofing component is spaced apart on the mounting surface;

[0008] An external waterproofing component is disposed on the side of the internal waterproofing component that is away from the mounting base;

[0009] The mounting component has an mounting end and a connecting end. The connecting end is connected to the side of the waterproof substrate facing the mounting base, and the mounting end is mounted on the mounting surface. The mounting end can move between a first leveling position away from the connecting end and a second leveling position close to the connecting end, thereby causing the inner waterproof component to move the outer waterproof component away from or close to the mounting surface.

[0010] In one embodiment, the internal waterproofing component includes a first connecting plate and a waterproof base plate, the waterproof base plate being spaced apart from the mounting surface and connected to the connecting end, and the first connecting plate being connected to the side of the waterproof base plate opposite to the mounting surface.

Both the second mortise and the second tenon extend in the horizontal direction, and the second tenon is mortised and tenoned with the second mortise.

[0018] In one embodiment, the mounting base is a wall, and the mounting assembly includes an expansion base, a screw, and a leveling nut. The expansion base, the screw, and the leveling nut all extend horizontally. The surface of the wall is provided with the mounting surface, and the mounting surface is provided with a mounting hole. The expansion base fills the mounting hole. One end of the screw extends into the mounting hole and is threadedly connected to the expansion base. The other end of the screw is hinged to the leveling nut. The leveling nut is connected to the inner waterproofing assembly. The expansion base forms the mounting end, and the leveling nut forms the connecting end.

[0019] In one embodiment, the mounting base is a floor, the mounting assembly includes a connecting ring and a support foot, the surface of the floor is provided with the mounting surface, the connecting ring is connected to the inner waterproof assembly, the support foot extends vertically, the top end of the support foot is threadedly connected to the connecting ring, the bottom end of the support foot abuts against the mounting surface, the connecting ring forms the connecting end, and the support foot forms the mounting end.

[0020] The technical solution of this utility model realizes the adjustment and positioning of the inner and outer waterproof components through the adjustable leveling function of the installation components. Combined with the double waterproof structure, it effectively solves the leakage problem caused by uneven base layer. At the same time, the modular structure simplifies the construction process and improves the convenience of maintenance, which can improve the reliability of waterproofing, shorten the construction cycle and reduce maintenance costs.

[0030] With the development of the construction industry, prefabricated buildings have gradually become an important development direction in the construction field due to their advantages such as fast construction speed, controllable quality, and environmental protection and energy saving. In prefabricated buildings, waterproof structures are required in areas such as indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls, which are areas with high water usage, making their waterproof performance particularly important.

[0031] Traditional waterproofing construction primarily employs on-site wet application methods, which present the following problems: The quality of traditional waterproofing is difficult to guarantee. The thickness and uniformity of the waterproofing material application depend heavily on the skill level of the workers, easily leading to missed areas, uneven thickness, and poor waterproofing performance. The construction cycle is long, requiring multiple procedures with waiting time between each, severely impacting the construction progress. In uneven substrates, traditional waterproofing systems lack effective leveling mechanisms, resulting in uneven surface material laying, affecting usability and aesthetics. Repairs are difficult; leaks often require large-scale removal of the surface material, leading to high repair costs and disruption to users' daily lives. The waterproofing structure is simplistic, relying on only a single waterproof layer and lacking multiple protective mechanisms, resulting in insufficient waterproofing reliability. Furthermore, the low standardization of traditional waterproofing construction processes makes it difficult to meet the requirements of prefabricated building industrial production, hindering the development of prefabricated buildings.

[0032] To solve this technical problem, this utility model proposes a prefabricated waterproof system.

[0033] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the prefabricated waterproof system includes an installation base 100, an inner waterproof component 200, an outer waterproof component 300, and an installation component 400. The surface of the installation base 100 is provided with an installation surface 101. The inner waterproof components 200 are spaced apart from the installation surface 101. The outer waterproof component 300 is disposed on the side of the inner waterproof component 200 away from the installation base 100. The installation component 400 is provided with an installation end and a connecting end. The connecting end is connected to the side of the waterproof substrate facing the installation base 100, and the installation end is installed on the installation surface 101. The installation end can move between a first leveling position away from the connecting end and a second leveling position close to the connecting end, correspondingly causing the inner waterproof component 200 to move the outer waterproof component 300 away from or close to the installation surface 101.

[0034] It should be noted that this application is applicable to prefabricated buildings where waterproof structures are required, such as: indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls.

[0035] It should be understood that the mounting base 100 has a mounting surface 101, the inner waterproof components 200 are spaced apart on the mounting surface 101, and the outer waterproof components 300 are located outside the inner components. The mounting component 400 has a movable mounting end and a connecting end. The connecting end is fixed to the inner waterproof component 200, and the mounting end can move between a first leveling position and a second leveling position, thereby adjusting the overall distance between the inner and outer waterproof components 300 and the mounting surface 101.

[0036] The mounting base 100 refers to the building structure that supports the waterproofing system, which can be a concrete wall 110 or a precast floor 120. The mounting surface 101 on its surface is a standardized connection interface. The inner waterproofing component 200 serves as the main waterproofing layer 500, forming an air gap through intervals, and can be a composite structure of inorganic boards and waterproof membrane. The outer waterproofing component 300 serves as the decorative surface layer carrier, allowing for quick replacement through detachable connections. The leveling mechanism in the mounting component 400 compensates for construction errors in the building substrate through mechanical displacement adjustment, such as threaded connections or hinged devices.

[0037] More specifically, when the surface of the mounting base 100 is uneven, the operator adjusts the horizontal position of the mounting end. Moving the mounting end away from the connection end causes the inner waterproofing component 200 to move outwards, increasing the distance between it and the mounting surface 101; conversely, moving it inwards decreases the distance. This adjustment process simultaneously changes the position of the outer waterproofing component 300, ensuring the decorative surface layer remains at the designed elevation. After leveling, the inner and outer waterproofing components 300 form a stable support through the connection end, maintaining the preset waterproofing layer spacing 500.

[0038] Compared to existing technologies, traditional fixed installations require precise control of the substrate flatness, while this solution achieves three-dimensional spatial adjustment through a movable installation end, allowing for substrate errors within ±15 mm. Existing single-layer waterproof structures are susceptible to construction quality issues; this solution's spaced arrangement of inner and outer components forms a double waterproof barrier, and the non-contact installation of the inner component with the substrate effectively blocks capillary seepage paths.

[0039] In the technical solution provided by this utility model, the adjustable leveling function of the installation component 400 enables the adjustment and positioning of the inner waterproof component 200 and the outer waterproof component 300. Combined with the double waterproof structure, it effectively solves the leakage problem caused by uneven base layer. At the same time, the modular structure simplifies the construction process and improves maintenance convenience, which can improve waterproof reliability, shorten the construction cycle and reduce maintenance costs. It solves the problem of waterproof layer 500 failure caused by base layer error in prefabricated buildings, and enables the surface decoration material to actively level under uneven base layer conditions. It improves the waterproof effect in prefabricated building structures where waterproof structures are required, such as indoor bathrooms, kitchens, balconies, basements, roofs and exterior walls.

[0040] In an embodiment of this utility model, the inner waterproof component 200 includes a first connecting plate 210 and a waterproof base plate 220. The waterproof base plate 220 is spaced apart from the mounting surface 101 and connected to the connecting end. The first connecting plate 210 is connected to the side of the waterproof base plate 220 away from the mounting surface 101.

[0041] It should be noted that the waterproof base plate 220 refers to a rigid plate that is spaced apart from the mounting surface 101. Specifically, it can be made of inorganic board, metal plate, or honeycomb core composite board, and is used to form a waterproof barrier and bear the installation force transmitted from the connection end. The first connecting plate 210 refers to a support structure fixedly connected to the waterproof base plate 220, and can be made of metal profile or engineering plastic, and is used to provide an mounting base for the external waterproof component 300 and distribute the load.

[0042] More specifically, the waterproof base plate 220 forms an adjustable connection with the mounting assembly 400 via a connecting end. When the mounting assembly 400 moves the waterproof base plate 220 between the first leveling position and the second leveling position, the gap between the waterproof base plate 220 and the mounting surface 101 changes accordingly, thereby compensating for the unevenness of the mounting base 100 surface. The first connecting plate 210 serves as an intermediate transition layer, forming a stable support surface above the waterproof base plate 220, allowing the external waterproof assembly 300 to be detachably installed via the second connecting plate 310. The spacing structure between the waterproof base plate 220 and the mounting surface 101 avoids stress concentration caused by direct contact, while also providing operating space for subsequent maintenance.

[0043] This embodiment combines a movable waterproof base plate 220 with a rigid first connecting plate 210 to achieve a dual waterproof structure while simultaneously achieving dynamic leveling. The modular structure allows the outer waterproof component 300 to be disassembled and repaired independently without damaging the overall waterproof layer 500, reducing maintenance costs and improving the reliability of leak prevention.

[0044] In embodiments of this utility model, the waterproof base plate 220 is an inorganic plate, a metal plate, a solid core plate, or a honeycomb core composite plate.

[0045] It should be noted that inorganic boards refer to boards made of inorganic non-metallic materials, such as cement fiberboard, calcium silicate board, or gypsum board. They are moisture-proof and corrosion-resistant, making them suitable for humid environments. Metal boards refer to boards made of metal materials, such as aluminum alloy boards, stainless steel boards, or galvanized steel boards. They possess high structural strength and enhance the deformation resistance of the 220 waterproof base plate. Solid core boards refer to boards without internal cavities, such as multi-layer solid wood boards, high-density fiberboard, or solid plastic boards. They prevent moisture from penetrating into the internal cavities, reducing the risk of leakage. Honeycomb core composite boards refer to boards composed of honeycomb core materials and surface materials. They can be made by combining aluminum honeycomb cores with metal or plastic surface layers, combining lightweight and high strength characteristics, and facilitating assembly and construction.

[0046] More specifically, the waterproof base plate 220, as the core structural layer of the inner waterproof component 200, achieves differentiated functions by selecting different materials. For example, in scenarios requiring high load-bearing capacity, metal plates or honeycomb core composite panels can be used to improve support performance; in humid or corrosive environments, inorganic plates or solid core plates can effectively prevent water vapor penetration. After the waterproof base plate 220 is connected to the installation component 400, its material properties ensure that no cracking or deformation occurs during the leveling process, thereby maintaining the stability of the outer waterproof component 300.

[0047] Traditional waterproofing systems typically use a single-material baseboard, such as cement board or ordinary wood, which suffers from problems like susceptibility to moisture and deformation, and insufficient impact resistance. This embodiment, however, offers a variety of material options, allowing for flexible matching to specific needs. For example, honeycomb core composite panels reduce weight while maintaining strength, metal panels can withstand high loads, and inorganic panels effectively inhibit mold growth, significantly improving the environmental adaptability and lifespan of the waterproofing system. This solves the problems of easy leakage and poor durability caused by the single material of the baseboard in traditional waterproofing systems. This embodiment, by using 220 waterproof baseboard material with different properties, effectively blocks water penetration, improves structural stability, and reduces maintenance frequency due to material defects. It meets the dual requirements of waterproofing performance and ease of construction in prefabricated building structures requiring waterproofing, such as indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls.

[0048] In an embodiment of this utility model, a waterproof layer 500 is filled between the first connecting plate 210 and the waterproof base plate 220.

[0049] It should be noted that the waterproof layer 500 refers to the sealing material filled between the first connecting plate 210 and the waterproof base plate 220. Specifically, it can be achieved by using prefabricated waterproof membranes such as thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), and ethylene propylene diene monomer (EPDM). Its function is to form a physical barrier by continuously covering the joint area to prevent moisture from penetrating along the joint interface.

[0050] More specifically, during assembly, after the waterproof base plate 220 is fixed to the mounting base 100 via the mounting assembly 400, the first connecting plate 210 is welded or bonded to the outer surface of the waterproof base plate 220. The gap between the two is filled by laying a whole sheet of waterproof membrane, for example, cutting TPO membrane into strips matching the gap size and fixing it to the contact surface between the connecting plate and the base plate by hot melting or adhesive bonding. Thus, the waterproof layer 500 not only covers the gap at the joint but also accommodates minor displacements caused by leveling operations, preventing waterproofing failure due to structural deformation. This embodiment forms multiple waterproof barriers by adding a prefabricated waterproof membrane layer between the connecting plate and the base plate. In the prior art, cracks easily occur at the joint due to material shrinkage or vibration, causing moisture to seep into the base layer along the cracks; however, in this solution, the ductility and tear resistance of the waterproof membrane can effectively compensate for deformation at the joint, while the standardized membrane laying process reduces human error. This solution addresses the leakage problems caused by improper joint treatment in traditional waterproofing systems, improving the reliability of waterproofing in prefabricated building structures where waterproofing is required, such as in interior bathrooms, kitchens, balconies, basements, roofs, and exterior wall-floor junctions. The standardized roll material simplifies the construction process, avoids the risks of uneven coating thickness or missed areas on-site, and provides a modular structural foundation for future maintenance with the option for partial replacement.

[0051] In an embodiment of this utility model, the external waterproof component 300 includes a second connecting plate 310 and a waterproof panel 320. The second connecting plate 310 is detachably connected to the side of the first connecting plate 210 away from the waterproof base plate 220, and the waterproof panel 320 is connected to the side of the second connecting plate 310 away from the first connecting plate 210.

[0052] It should be noted that the second connecting plate 310 refers to the transition structure used to connect the first connecting plate 210 and the waterproof panel 320. It can be made of metal or plastic, and its surface can be provided with clips or bolt holes for detachable connection. The waterproof panel 320 refers to the decorative or protective layer covering the outside of the second connecting plate 310. It can be made of ceramic tiles, slabs, or composite panels, and is connected to the second connecting plate 310 by adhesive or mechanical fixing. Detachable connection means that the second connecting plate 310 and the first connecting plate 210 are fixed in a separable manner, which can be achieved through mortise and tenon joints, clip-on structures, or bolt connections, facilitating future maintenance or replacement.

[0053] More specifically, the second connecting plate 310 is detachably connected to the first connecting plate 210 via clips or bolts, and the waterproof panel 320 is installed on the outside of the second connecting plate 310 by adhesive or mechanical fixing. When the waterproof panel 320 needs to be repaired or replaced, the second connecting plate 310 can be separated from the first connecting plate 210 without damaging the structure of the inner waterproof component 200. The connection method between the waterproof panel 320 and the second connecting plate 310 can be selected according to actual needs; for example, tiles are adhered with cement mortar, slabs are fixed with structural adhesive, and composite panels are locked with bolts.

[0054] Traditional waterproofing systems typically use a fixed connection between the surface layer and the substrate. If the surface layer is damaged, the entire system must be removed for repair. This embodiment, however, utilizes a detachable second connecting plate 310 to allow for independent replacement of the surface layer, reducing maintenance costs. Furthermore, existing technologies lack a transition structure between the surface layer and the waterproofing layer 500, making leveling difficult. In this solution, the second connecting plate 310 serves as a leveling reference surface, allowing for fine-tuning of the surface layer height by adjusting its connection position with the first connecting plate 210. This solves the problem of difficult surface layer repair in traditional waterproofing systems, enabling rapid partial replacement. The detachable design of the second connecting plate 310 and the first connecting plate 210 reduces the difficulty of leveling operations. The dual connection structure enhances the stability of the surface layer installation, preventing cracking or detachment due to uneven substrate.

[0055] In embodiments of this utility model, the waterproof panel 320 is a ceramic tile, rock slab, marble slab, inorganic board, metal board, or composite board.

[0056] It should be noted that ceramic tiles refer to hard, plate-like materials made from clay, specifically glazed tiles or unglazed tiles. Their smooth surface and wear resistance make them suitable for waterproofing in prefabricated building structures, such as bathrooms, kitchens, balconies, basements, roofs, and exterior walls. Sintered stone slabs are made from natural stone through high-temperature pressing, often using a sintering process. They are impact-resistant and corrosion-resistant, suitable for waterproofing in humid environments. Marble slabs are decorative panels cut from natural marble, often polished. Their beautiful texture and impermeability enhance the visual appeal of waterproofing areas in prefabricated building structures, such as bathrooms, kitchens, balconies, basements, roofs, and exterior walls. Inorganic boards are made primarily of cement, gypsum, or silicates, often using fiber reinforcement. They are moisture-proof and fire-resistant, suitable for applications with high environmental protection requirements. Metal sheets refer to sheets made of aluminum alloy or stainless steel, which can be produced using stamping processes. They are lightweight and weather-resistant, and can meet the structural stability requirements under complex installation conditions. Composite sheets refer to sheets formed by laminating two or more materials, which can be achieved using a honeycomb core and panel composite structure. They combine lightweight and high strength characteristics, which helps to reduce the load on the overall system.

[0057] More specifically, the waterproof panel 320 forms a modular structure through a detachable connection between the second connecting plate 310 and the first connecting plate 210. When the flatness of the mounting base 100 needs to be adjusted, the waterproof panel 320 can be moved as a whole by moving the mounting assembly 400. Hard materials such as ceramic tiles or sintered stone can maintain surface integrity during leveling, while inorganic boards or composite boards avoid deformation due to their rigidity. The lightweight characteristics of metal boards and composite boards reduce the difficulty of leveling operations, while the standardized dimensions of marble boards and ceramic tiles facilitate local replacement and maintenance. The material selection of the waterproof panel 320 can be combined according to actual needs; for example, sintered stone can be used in impact-prone areas, marble boards in decorative areas, and composite boards in areas with high lightweight requirements.

[0058] In traditional prefabricated building structures, areas requiring waterproofing, such as indoor bathrooms, kitchens, balconies, basements, roofs, and exterior walls, often use single-layer ceramic tiles or stone as surface materials. Repairs require destructive removal. This solution, however, utilizes a detachable connection structure, allowing for individual replacement of the waterproof panel 320. Existing surface materials often struggle to adapt to substrate leveling requirements. In this embodiment, lightweight materials combined with a modular structure allow for synchronized displacement with the installation components 400. Traditional surface materials lack diverse options; this solution combines multiple materials to satisfy both decorative and functional needs. It enables rapid replacement and partial repair of the waterproof panel 320, reducing maintenance costs. The combination of rigid materials and an adjustable structure improves substrate adaptability, ensuring surface flatness. Diverse material choices meet the decorative, load-bearing, and durability requirements of different scenarios, extending the service life of the waterproofing system.

[0059] In an embodiment of this utility model, a composite adhesive layer 600 is filled between the second connecting plate 310 and the first connecting plate 210.

[0060] It should be noted that the composite adhesive layer 600 refers to an adhesive layer formed by mixing two or more materials, specifically polyurethane adhesive, epoxy resin adhesive, silicone adhesive, or acrylic adhesive. Its function is to enhance the connection strength between the second connecting plate 310 and the first connecting plate 210, while forming a sealed interface to prevent moisture penetration. The composite adhesive layer 600 has elastic deformation capability, which can adapt to the slight displacement generated during the leveling process of the installation component 400, avoiding stress concentration or sealing failure caused by rigid connection.

[0061] More specifically, during assembly, the composite adhesive layer 600 is uniformly applied to the contact surfaces of the first connecting plate 210 and the second connecting plate 310, and pressure is used to ensure a tight bond between them. After curing, the composite adhesive layer 600 forms a continuous adhesive surface, which not only fixes the relative positions of the outer waterproof component 300 and the inner waterproof component 200, but also fills the gaps between the connecting plates. When the outer waterproof component 300 needs to be disassembled for maintenance, the composite adhesive layer 600 can be softened with a special solvent or separated by mechanical cutting, maintaining the integrity of the connecting plate surface and facilitating reinstallation. In addition, the composite adhesive layer 600, as a supplementary waterproof layer 500, forms a double protection with the waterproof layer 500 of the inner waterproof component 200, further reducing the risk of leakage.

[0062] This embodiment improves the sealing reliability of the contact surface between the first connecting plate 210 and the second connecting plate 310, and effectively absorbs structural deformation during the leveling process through elastic bonding, avoiding damage to the waterproof layer 500 caused by stress concentration.

[0063] In an embodiment of this utility model, a first mortise 201 is provided on the side of the first connecting plate 210 facing away from the waterproof base plate 220, and a first tenon 330 is provided on the side of the second connecting plate 310 facing away from the waterproof panel 320. Both the first mortise 201 and the first tenon 330 extend horizontally, and the first tenon 330 is mortised and tenoned with the first mortise 201; or,

[0064] The first connecting plate 210 has a second tenon 230 on the side away from the waterproof base plate 220, and the second connecting plate 310 has a second mortise 301 on the side away from the waterproof panel 320. Both the second mortise 301 and the second tenon 230 extend in the horizontal direction, and the second tenon 230 and the second mortise 301 are connected by a tenon and mortise.

[0065] It should be noted that the first mortise 201 refers to a groove structure set on the first connecting plate 210, which can be achieved by machining or molding, and is used to accommodate the first tenon 330 to form a tight fit. The first tenon 330 refers to a protrusion structure set on the second connecting plate 310, which can be designed with dimensions and shapes matching the first mortise 201, and can be quickly positioned and fixed by inserting into the mortise. The structural principle of the second tenon 230 and the second mortise 301 is the same as described above, the difference being the interchangeability of the tenon and mortise positions. Horizontal extension means that the length direction of the tenon and mortise is parallel to the surface of the mounting base 100, which can be achieved by straight grooves and protrusions to ensure alignment along the horizontal axis during connection. Mortise and tenon connection refers to the connection between components through a convex-concave mechanical structure, which can be designed with standardized dimensions to facilitate mass production and assembly.

[0066] More specifically, during installation, when it is necessary to connect the outer waterproofing component 300 to the inner waterproofing component 200, the operator can push the first tenon 330 of the second connecting plate 310 horizontally into the first mortise 201 of the first connecting plate 210 until the two are fully engaged. The horizontal extension characteristics of the tenon and mortise eliminate the need to adjust the vertical positional deviation during connection; positioning can be completed simply by moving along a single axis. When the second tenon 230 and second mortise 301 are used, rapid assembly is also achieved through horizontal sliding. This structure allows for horizontal adjustment of the position of the outer waterproofing component 300 even when there are slight unevennesses on the wall or floor, avoiding installation difficulties caused by uneven substrates. For disassembly and maintenance, the inner and outer components can be separated simply by sliding horizontally in the opposite direction, without damaging the waterproofing layer 500 or using special tools.

[0067] Traditional waterproofing systems often rely on adhesives or bolts for connecting internal and external components, leading to difficulties in disassembly and low leveling accuracy. This solution, however, achieves reversible connections through mortise and tenon joints, ensuring connection strength while simplifying installation and maintenance. Existing vertical mortise and tenon joints are prone to loosening under gravity, while the horizontally extending mortise and tenon design effectively avoids this problem and reduces the space requirements during assembly. This embodiment solves the problems of difficult leveling and high maintenance costs in traditional waterproofing systems. The mortise and tenon connection structure allows the external waterproofing component 300 to be flexibly adjusted horizontally to adapt to uneven surfaces of the mounting base 100, reducing the complexity of on-site construction. Standardized mortise and tenon interfaces improve component interchangeability, facilitating industrial production and rapid assembly. The detachable design allows for partial repairs without damaging the overall waterproofing structure, significantly reducing maintenance costs and time. Furthermore, the mechanical connection method replaces adhesives, reducing the use of chemical materials and improving the environmental friendliness of the construction process.

Figure 1 In an embodiment of this utility model, the mounting base 100 is a wall 110, and the mounting assembly 400 includes an expansion base 410, a screw 420, and a leveling nut 430. The expansion base 410, screw 420, and leveling nut 430 all extend in the horizontal direction. The surface of the wall 110 is provided with a mounting surface 101, and the mounting surface 101 is provided with a mounting hole 102. The expansion base 410 fills the mounting hole 102. One end of the screw 420 extends into the mounting hole 102 and is threadedly connected to the expansion base 410. The other end of the screw 420 is hinged to the leveling nut 430. The leveling nut 430 is connected to the inner waterproof assembly 200. The expansion base 410 forms the mounting end, and the leveling nut 430 forms the connecting end.

[0069] It should be noted that the expansion base 410 refers to the fixing component that fills the mounting hole 102, which can be implemented using a metal expansion bolt or a plastic expansion tube, and is used to form a stable support structure inside the wall 110. The screw 420 refers to a threaded rod-shaped connector, which can be made of stainless steel, and achieves horizontal fixation through its threaded engagement with the expansion base 410. The leveling nut 430 refers to an adjusting component with internal threads, which can be implemented using a hexagonal nut. Its hinged design with the screw 420 allows for fine-tuning of the horizontal angle, thereby moving the inner waterproof component 200. The mounting hole 102 refers to a hole pre-drilled in the surface of the wall 110, which can be formed using drilling equipment, to accommodate the expansion base 410. The hinge refers to the rotatable connection between the screw 420 and the leveling nut 430, which can be achieved through a ball-head hinge structure, allowing the leveling nut 430 to rotate freely within a certain angle range.

[0070] More specifically, when it is necessary to adjust the distance between the inner waterproofing component 200 and the mounting surface 101, the relative position of the leveling nut 430 and the screw 420 can be changed by rotating the leveling nut 430. When the leveling nut 430 moves horizontally, it drives the inner waterproofing component 200 to move synchronously, thereby increasing or decreasing the gap between the waterproof base plate 220 and the mounting surface 101. The expansion base 410 remains fixed within the mounting hole 102, providing horizontal support for the screw 420. The hinged design of the screw 420 and the leveling nut 430 can compensate for the angular deviation caused by local unevenness of the wall surface 110, ensuring that the force on each component is uniform during the leveling process.

[0071] In some specific embodiments, the expansion base 410 may be a nylon expansion tube with a barbed structure, and the diameter of the mounting hole 102 may be slightly smaller than the outer diameter of the expansion tube to enhance friction. The thread length of the screw 420 may be set to 1.2 times the length of the expansion base 410 to ensure sufficient screw-in depth. The internal thread of the leveling nut 430 may be set to a fine thread, producing a displacement of 0.5 mm per rotation, facilitating precise control of leveling accuracy.

[0072] Compared to existing technologies, traditional wall waterproofing systems often use fixed embedded parts, making post-installation position adjustments impossible. This solution, however, combines a horizontally arranged expansion base 410 with adjustable nuts, achieving bidirectional leveling while maintaining structural stability. Existing technologies often use vertical support feet 450 for leveling, which are easily affected by uneven ground. This solution's horizontal leveling mechanism directly eliminates flatness errors inherent in the wall surface. In this embodiment, the horizontal leveling function of the wall mounting component 400 effectively solves the problem of waterproofing layer 500 deformation caused by uneven wall surface 110. The adjustable structure reduces the requirements for wall 110 flatness during construction, reducing the time required for base layer preparation. The hinged design avoids stress concentration that may occur with rigid connections, improving the system's long-term stability. The tight fit between the expansion base 410 and the wall 110 ensures the overall rigidity of the mounting component 400 during leveling, preventing cracking of the waterproofing layer 500 due to loosening.

[0073] Please continue reading. Figure 2 In an embodiment of this utility model, the mounting base 100 is a floor 120, and the mounting component 400 includes a connecting ring 440 and a support foot 450. The surface of the floor 120 is provided with a mounting surface 101. The connecting ring 440 is connected to the inner waterproof component 200. The support foot 450 extends vertically, and the top end of the support foot 450 is threadedly connected to the connecting ring 440. The bottom end of the support foot 450 abuts against the mounting surface 101. The connecting ring 440 forms a connecting end, and the support foot 450 forms a mounting end.

[0074] It should be noted that the connecting ring 440 refers to the ring structure fixedly connected to the inner waterproof component 200. Specifically, it can be a metal ring or a high-strength plastic ring. It forms an adjustable fixing point with the support foot 450 via a threaded connection, facilitating the adjustment of the height of the inner waterproof component 200. The support foot 450 refers to a columnar support structure extending vertically. Specifically, it can be a metal rod with external threads. An anti-slip pad or rubber base can be installed at the bottom. By rotating the support foot 450, the thread engagement length between it and the connecting ring 440 is changed, thereby adjusting the height of the inner waterproof component 200 relative to the mounting surface 101 of the floor 120.

[0075] More specifically, when the mounting base 100 is the floor 120, the mounting surface 101 is the surface of the floor 120, and the bottom of the support foot 450 directly abuts against the surface of the floor 120. By rotating the support foot 450, the thread engagement depth between its top and the connecting ring 440 can be adjusted, allowing the inner waterproof component 200 to be raised or lowered to adapt to uneven surfaces of the floor 120. The connecting ring 440 is fixedly connected to the inner waterproof component 200, and the support foot 450 achieves fine-tuning of its height through thread adjustment, ensuring that the distance between the inner waterproof component 200 and the outer waterproof component 300 meets the requirements, thus preventing cracking or leakage of the waterproof layer 500 due to uneven ground.

[0076] Traditional floor waterproofing systems typically employ a fixed-height support structure, which struggles to adapt to uneven ground surfaces, leading to uneven stress on the waterproofing layer 500. This embodiment, however, utilizes a threaded support leg 450 structure, allowing for flexible height adjustment without requiring ground leveling, simplifying the construction process and reducing the risk of waterproofing layer 500 failure due to uneven ground. It solves the leveling difficulty problem of traditional floor waterproofing systems, achieving precise height adjustment through the threaded engagement of the support leg 450 and connecting ring 440. This ensures installation stability between the inner waterproofing component 200 and the outer waterproofing component 300, reducing the risk of cracking in the waterproofing layer 500 due to uneven ground, while also lowering construction difficulty and maintenance costs.
