Description

Technical Field

[0001] This application relates to the field of decoration, and in particular to a cement-free waterproof floor structure. Background Technology

[0002] In the field of building interior decoration, waterproofing of store floors usually adopts a wet construction method of leveling with cement mortar and applying a coating or roll waterproofing material. The surrounding area is then sealed with an upturned waterproof layer, a water-retaining sill, or a skirting board to the walls, door frames, columns, etc., thus forming a basic waterproof and drainage structure. However, the construction cycle is long, there are many procedures, and it is highly dependent on the site conditions.

[0003] To shorten downtime, quick-installation stores are gradually adopting dry-layout structures such as adjustable supports, raised floors, and metal trays to replace traditional cement leveling. However, existing solutions mostly focus on rapid leveling and surface layer laying, and the surrounding junctions are usually only treated with simple strips, edge banding, or localized caulking, lacking a continuous enclosed waterproof and internal drainage channel that is integrated with the overall ground structure.

[0004] Most existing technologies use fixed support components and brackets, which often require drilling holes in the base ground or surrounding facades for expansion and fixing, or forming segmented and discontinuous edge structures. This makes it difficult to form a continuous and closed waterproof enclosure at the junction of the store floor and walls, door frames, columns, etc. Water seeping under the surface layer is difficult to be completely collected and drained in an organized manner. Furthermore, the support components are prone to damage or weakening of the waterproof layer, making it difficult to simultaneously meet the comprehensive requirements of cement-free construction, reliable load-bearing, durable sealing, thermal expansion and contraction displacement compensation, and maintainability.

[0012] In at least one embodiment of this application, the end of the folded edge away from the plate-shaped bottom is provided with a flange extending along the length direction of the folded edge, the flange being formed by bending the folded edge and used to define the boundary position of the folded edge.

[0013] In at least one embodiment of this application, the supporting component is continuously arranged along the folded edge of the waterproof component to form a closed frame structure.

[0014] In at least one embodiment of this application, an adhesive fixing part is provided between the base of the support component and the plate-shaped bottom of the waterproof component, and between the top seat of the support component and the cover plate of the support component.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0022] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a cement-free waterproof floor structure 100 is arranged on the base surface 101 of a building. The base surface 101 can be the original concrete floor slab of a shopping mall, street shop or office building. No cement mortar leveling and slope construction is required. Only basic surface cleaning is needed to serve as the load-bearing foundation and installation interface of this structure, thereby avoiding wet construction and long-term maintenance.

[0023] In one specific embodiment, the waterproof component 10 is integrally stacked on the base surface 101, with its lower side adhering to the base surface 101 and its upper side forming a plate surface for receiving rainwater. The waterproof component 10 has a plate-shaped bottom 11 and a folded edge portion 12 continuously folded up along the periphery of the plate-shaped bottom 11. The plate-shaped bottom 11 is preferably an integrally formed metal plate, which, by being laid in a large size on the base surface 101, forms a continuous and uninterrupted water-receiving surface for collecting surface seepage or cleaning water, condensate, etc., preventing water from directly seeping into the original structural floor slab. The folded edge portion 12 is folded upward relative to the plate-shaped bottom 11, forming an upward-turned boundary around the plate-shaped bottom 11, making the plate-shaped bottom 11 a tray-like water-receiving area, preventing water from flowing out from the edge, ensuring that the water is confined inside the waterproof component 10 and can be guided to a predetermined drainage position. By integrating or reliably connecting the plate-shaped bottom 11 with the folded edge 12, the number of overlapping seams can be reduced, the overall waterproof reliability can be improved, and the deformation requirements during frequent disassembly and assembly and use in quick-installation stores can be adapted.

[0024] In one specific embodiment, the support component 20 is located at the outer edge of the waterproof component 10, and is used to form a rigid frame and drainage space between the store floor and the surrounding facade under cement-free conditions. The support component 20 includes a perimeter panel 21 arranged along the perimeter of the store and a cover plate 22 connected to the upper end of the perimeter panel 21. The perimeter panel 21 is formed by connecting multiple sections of upright boards end to end, forming a closed frame on the plane corresponding to the outer edge of the store. Its inner side is adjacent to the folded edge 12 of the waterproof component 10, and its outer side is adjacent to facade components such as walls, door frames, or columns. The cover plate 22 is continuously arranged above the closed frame, and its edge is fixedly connected to the upper end of the perimeter panel 21, so that the perimeter panel 21 and the cover plate 22 together form a strip-shaped and entirely closed drainage cavity 23. The opening of the drainage cavity 23 faces the waterproof component 10, and is used to receive water seeping down from the upper surface layer and guide the water to the waterproof component 10.

[0025] In one specific embodiment, the support component 20 may be formed by square tube profiles or by welding plates into box-shaped or trough-shaped components. The vertical sidewalls of the component serve as enclosure plates 21, and the inwardly extending horizontal plates serve as cover plates 22. The two enclose the drainage cavity 23.

[0026] Furthermore, the drainage cavity 23 is arranged adjacent to the folded edge 12 of the waterproof component 10, forming a connected space between the interior and the upper ground structure and the lower waterproof component 10. When water seeps into this edge area from the interior surface layer, it can first enter the drainage cavity 23, and then flow along the drainage cavity 23 under the action of gravity and be guided to the lower area or drain outlet connected to the waterproof component 10, thus achieving organized discharge. The supporting component 20 formed by the enclosure panel 21 and the cover plate 22 also provides a structural support interface, which can be used to fix upper components such as door frames, columns, and lightweight partitions, so that these upper components do not have to directly damage the waterproof component 10 and the base surface 101, thereby taking into account both structural installation and waterproof integrity.

[0027] Furthermore, a sealing layer 30 is provided between the folded edge 12 and the supporting component 20. The sealing layer 30 is arranged on the overlap area 31 formed by the outer side of the folded edge 12 and the surrounding panel 21 and cover plate 22, covering the entire overlap area in a continuous strip or surface shape. This sealing layer 30 seals any small channels such as seams, gaps, and screw holes that may exist between the folded edge 12 and the supporting component 20, preventing water from overflowing from the interface or seeping into the base surface 101. At the same time, it allows for slight relative displacement between the folded edge 12 and the supporting component 20 during temperature changes or structural deformation without compromising the sealing effect. The sealing layer 30 can be formed of elastic sealant, waterproof tape, etc., maintaining continuous waterproofing while possessing a certain degree of flexibility to adapt to assembly errors and thermal expansion and contraction at quick-installation store nodes.

[0028] In one specific embodiment, the support component 40 is arranged inside the drainage cavity 23. The lower end of the support component 40 abuts against the plate-shaped bottom 11 of the waterproof component 10, and the upper end abuts against the cover plate 22 of the support component 20. In this embodiment, the support components 40 are distributed at certain intervals along the internal area of ​​the store within the drainage cavity 23. They transmit vertical loads through surface contact with the plate-shaped bottom 11 and the cover plate 22, and are used to support the upper structure such as the raised floor, lightweight leveling plate, or equipment foundation installed above them. Since the support component 40 is confined within the drainage cavity 23 and directly abuts against the waterproof component 10 and the support component 20, ground leveling and load transfer can be completed without penetrating the waterproof component 10 with anchor bolts or damaging the base surface 101. This avoids the hidden dangers of penetrating the waterproof and causing expansion in traditional methods, and ensures the integrity and continuity of the waterproof layer. The combination of the support component 40 and the drainage cavity 23 allows the upper ground system and the lower waterproofing system to be spatially separated but mechanically continuous, which not only meets the needs of quick-installation stores for adjustable leveling and disassembly, but also maintains the independence and maintainability of the waterproofing system.

[0029] Under the above structural relationship, during construction, waterproof components 10 are first laid on the base surface 101 without cement leveling treatment, so that the plate-shaped bottom 11 covers the target area and forms a perimeter upturn through the folded edge 12; then, support components 20 are installed along the outside of the folded edge 12, and drainage cavity 23 is formed by the surrounding plate 21 and the cover plate 22, and a continuous sealing layer 30 is formed in the overlapping area of ​​the folded edge 12 and the support components 20 to achieve the enclosure and waterproofing of the perimeter nodes; then, several support components 40 are arranged in the drainage cavity 23, so that their upper and lower ends abut against the plate-shaped bottom 11 and the cover plate 22 respectively, and the upper adjustable ground system or modular paving layer is built accordingly. During use, if moisture seeps through the surface layer or enters the system from the store entrance, it will first fall into the support component 20 and its drainage chamber 23, and be guided to the plate-shaped bottom 11 of the waterproof component 10. Then, it will collect at the drain outlet along the preset slope or drainage path. The whole process does not require cement mortar leveling, nor will it damage the waterproof component 10 through the support component 40. Therefore, installation can be completed in a short time, while achieving continuous closed waterproofing, organized internal drainage, and stable load-bearing.

[0030] In one specific embodiment, a boundary corner assembly 50 is provided along the inner side of the supporting assembly 20. The boundary corner assembly 50 is preferably a metal L-shaped member, with one leg positioned close to the cover plate 22 or enclosure plate 21 of the supporting assembly 20, and the other leg extending towards the interior side. This allows the boundary corner assembly 50 to be located entirely on the inner edge of the supporting assembly 20, and to be positioned opposite the folded edge portion 12 of the waterproofing assembly 10. This arrangement forms a rigid edge line that extends continuously along the perimeter of the store, providing a stable installation reference for the door frame, pillars, or interior finish, and defining a clear overlap area 31 between the boundary corner assembly 50 and the folded edge portion 12. This allows the sealing layer 30 to be continuously laid on the rigid interface, thereby improving the dimensional stability and sealing reliability at the junction and preventing damage to the waterproofing structure due to deformation or displacement of the finishing components.

[0031] Furthermore, the corner component 50 is reliably connected to the support component 20 via fasteners 51. The fasteners 51 can be screws or bolts, passing through the corresponding limbs of the corner component 50 from top to bottom and tightened to the cover plate 22 or the surrounding plate 21, fixing the position of the corner component 50 relative to the support component 20 and making it independent of the waterproof component 10 body. The corner component 50 forms a rigid edge trim independent of the waterproof tray. The load of the upper door frame or column is preferentially borne by the corner component 50 and the support component 20, and will not act directly on the waterproof component 10 through the fasteners, avoiding drilling holes in the folded edge 12 and the plate-shaped bottom 11, thus ensuring the integrity of the waterproof component 10. Simultaneously, the fasteners 51 press the corner component 50 tightly against the support component 20, creating a restricted clamping state for the sealing layer 30 between the corner component 50 and the folded edge 12, effectively reducing the risk of micro-cracks and water seepage.

[0032] In one specific embodiment, the support component 40 is designed as an adjustable column structure. The support component 40 includes a base 41, a top seat 42, and a column portion 43 disposed between the base 41 and the top seat 42. The base 41 is a plate-shaped or disc-shaped component, and its lower surface is in contact with and attached to the plate-shaped bottom 11 of the waterproof component 10. The base 41 is attached to the plate-shaped bottom 11 through the fixing layer 60 or its own weight, thereby stably positioning the support component 40 on the plate-shaped bottom 11. The base 41 and the plate-shaped bottom 11 of the waterproof component 10 are connected by surface contact, ensuring that the support component 40 bears the upper load and evenly transfers it to the water-bearing surface of the waterproof component 10 without damaging the waterproof component 10 or causing local punctures.

[0033] Furthermore, the top seat 42 is located at the upper end of the column portion 43. The upper surface of the top seat 42 contacts and abuts against the cover plate 22 of the support assembly 20, and is connected to the cover plate 22 through surface contact. The connection between the top seat 42 and the cover plate 22 of the support assembly 20 ensures that the support assembly 40 transfers the load to the support assembly 20. The column portion 43 is located between the base 41 and the top seat 42, and its height is adjustable through a telescopic joint. The telescopic joint of the column portion 43 is achieved through a sleeve fit or an internal and external thread adjustment structure. The height of the support assembly 40 can be precisely adjusted according to the undulation of the base surface 101 and the laying error of the waterproof assembly 10, so that the top seat 42 and the cover plate 22 of the support assembly 20 form a support plane with a uniform elevation.

[0034] In one specific embodiment, a fixing layer 60 is provided between the base portion 41 of the support component 40 and the plate-shaped bottom 11 of the waterproof component 10, and between the top portion 42 and the cover plate 22 of the support component 20. The fixing layer 60 is connected by structural adhesive, which provides high-strength adhesion and a certain degree of elasticity to ensure that the support component 40 will not undergo excessive displacement due to temperature or load changes during load bearing. The fixing layer 60 fixes the connection between the base 41 of the support component 40 and the waterproof component 10, and between the top portion 42 and the support component 20, while avoiding penetration of the waterproof layer or the use of traditional fasteners (such as screws or expansion bolts), thereby maintaining the integrity of the waterproof component 10.

[0035] With this structure, the connection between the support component 40 and the waterproof component 10 and the support component 20 is stable and reliable, which can effectively transfer the upper load to the base surface 101 and ensure the ground leveling function, reliable load bearing and the integrity of the waterproof system.

[0036] In one specific embodiment, the support components 40 are arranged in rows and columns within the drainage cavity 23 along the length and width directions of the supporting component 20. The base 41 of each support component 40 abuts against the plate-shaped bottom 11 of the waterproof component 10, and the top seat 42 abuts against the cover plate 22 of the supporting component 20. The support components 40 are arranged at uniform intervals within the drainage cavity 23 to form an array structure, ensuring that there is an equal spacing between each support component 40, and that the structural direction of each support component 40 is parallel to the length and width directions of the drainage cavity 23.

[0037] Specifically, the support components 40 are arranged in a staggered pattern, both horizontally and vertically, within the drainage chamber 23. The spacing between each row of support components 40 is equal, and the rows are also evenly spaced. This arrangement allows the support components 40 to distribute the load evenly without obstructing water flow. The arrangement of the support components 40 helps to create a uniform bearing surface throughout the drainage chamber 23, ensuring the stability of the ground system.

[0038] In one specific embodiment, the waterproof component 10 is a metal plate, wherein the plate-shaped bottom 11 of the waterproof component 10 is integrally bent with a folded edge 12 folded along its periphery. The plate-shaped bottom 11 of the metal plate is made of metal material (such as steel plate, stainless steel plate or aluminum plate) and is manufactured by machining or forming process. The lower surface of the plate-shaped bottom 11 is in direct contact with the substrate surface 101, thereby ensuring that the waterproof component 10 can stably bear surface moisture and prevent it from penetrating into the substrate surface 101.

[0039] Furthermore, the folded edge 12 is formed by folding up the edge of the metal plate. This folded edge 12 extends around the perimeter of the plate-shaped bottom 11, giving the entire waterproof assembly 10 a tray-like shape. The folded edge 12 enables the waterproof assembly 10 not only to retain water but also to effectively seal off water flow, preventing moisture from leaking out from the edges. The height and shape of the folded edge 12 can be designed according to different construction requirements to ensure its waterproofing effect in practical applications.

[0040] In this embodiment, the metal plate of the waterproof component 10 is integrally bent, with the plate-shaped bottom 11 and the folded edge 12 seamlessly connected. This avoids the seam problems that may exist in traditional waterproof layers and reduces the risk of moisture seeping through seams. Furthermore, this integral bending design improves the overall rigidity and compressive strength of the waterproof component 10, enabling it to withstand loads from above without deformation. Using a metal plate as the material for the waterproof component 10 gives it good corrosion resistance, durability, and thermal stability.

[0041] In one specific embodiment, the end of the folded edge 12 of the waterproof component 10 away from the plate-shaped bottom 11 is provided with a flange 13 extending along the length direction of the folded edge 12. The flange 13 is formed by further bending one end of the folded edge 12, and the bent portion extends along the edge of the folded edge 12 to form a small outwardly protruding flange. The main function of the flange 13 is to define the boundary position of the folded edge 12, so that the folded edge 12 remains in a fixed position during installation and to prevent the folded edge 12 from shifting or deforming due to external forces during use.

[0042] Furthermore, the shape and size of the flange 13 can be designed according to actual needs, typically as a continuous bend along the edge of the folded edge 12. The height and width of the flange 13 are generally designed to effectively constrain the folded edge 12 and maintain good fit with surrounding components (such as the support assembly 20). Through this design, the flange 13 not only enhances the structural stability of the folded edge 12 but also ensures that the waterproof assembly 10 accurately mates with the inner side of the support assembly 20 during installation, forming an effective waterproof seal.

[0043] Specifically, the flange 13 forms a certain contact surface with the surrounding plate 21 or cover plate 22 of the supporting component 20. When the waterproof component 10 is installed in place, the flange 13 can provide additional restraint to the folded edge 12, ensuring that the waterproof component 10 will not shift or become unstable during long-term use, thereby further improving the sealing and stability of the overall structure.

[0044] In one specific embodiment, the supporting component 20 is continuously arranged along the folded edge 12 of the waterproof component 10, forming a closed frame structure. Specifically, the surrounding plate 21 of the supporting component 20 is continuously arranged around the folded edge 12 of the waterproof component 10, with the lower end of the surrounding plate 21 contacting the folded edge 12 to form a closed frame that completely surrounds the waterproof component 10. The cover plate 22 is connected to the upper end of the surrounding plate 21. Through this design, the supporting component 20 closes the folded edge 12 of the waterproof component 10, ensuring that the edge of the waterproof component 10 is firmly fixed and that the load from the upper surface layer can be effectively transferred to the waterproof component 10.

[0045] Furthermore, the enclosure 21 of the supporting component 20 contacts the folded edge 12 of the waterproof component 10, and a closed frame structure is formed between the enclosure 21 and the cover plate 22, ensuring that water flow is confined within the area of ​​the waterproof component 10 and guided to a predetermined location through the drainage channel. In this way, the supporting component 20 can not only support the weight of the upper component, but also ensure the integrity of the waterproof system and prevent water from seeping into the surrounding area.

[0046] In one specific embodiment, a ground isolation layer 70 is provided between the base surface 101 and the plate-shaped bottom 11 of the waterproof component 10. The ground isolation layer 70 is typically made of flexible waterproof material or an isolation gasket and is installed between the base surface 101 and the plate-shaped bottom 11 of the waterproof component 10. The function of the ground isolation layer 70 is to prevent the plate-shaped bottom 11 of the waterproof component 10 from directly contacting the base surface 101, thereby preventing moisture or impurities on the base surface 101 from affecting the waterproof performance of the waterproof component 10.

[0047] Furthermore, the ground isolation layer 70 can also provide a certain degree of elasticity, preventing the waterproof component 10 from being directly affected by the unevenness of the substrate surface 101 during load-bearing, thereby enhancing the stability and durability of the waterproof component 10. The ground isolation layer 70 is usually laid in the form of an elastic material or isolation membrane, which has water resistance, weather resistance, and a certain buffering effect, ensuring the long-term stability of the waterproof layer and improving the waterproofing effect.

[0048] By setting up a ground isolation layer 70, the contact surface between the waterproof component 10 and the base surface 101 is effectively isolated, avoiding potential problems caused by water penetration and uneven ground.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
