Description

Technical Field

[0001] This utility model relates to the field of bathroom waterproofing technology, and in particular to a water-stopping sill structure. Background Technology

[0002] Bathrooms typically include a shower room and a dry area. Water barriers are usually installed between the bathroom and other living areas, as well as between different areas within the bathroom, to prevent water from overflowing and to ensure the separation of wet and dry areas in the shower area.

[0003] Currently, the mainstream structure for waterstops in the industry is reinforced concrete. This involves first positioning the waterstop on the ground, drilling holes in the predetermined concrete wall or floor slab to insert reinforcing bars, fabricating and installing formwork according to the design dimensions and shape, and finally pouring concrete within the formwork. Reinforced concrete structures are not only complex to operate and technically demanding, leading to long construction cycles and reduced efficiency, but the depth and angle of the reinforcing bars, as well as the sealing of the formwork, directly affect the final quality of the waterstop. Due to the complex on-site construction environment, problems such as inadequate reinforcing bar placement, formwork leakage, insufficient concrete compaction, or internal air bubbles and voids can easily occur, resulting in technical issues that make quality assurance difficult and pose a risk of leakage.

[0014] Furthermore, the aforementioned water-stop structure also includes: a U-shaped stone water-stop strip, which is covered by a layer of mortar on the top of the water-stop steel plate located at the shower partition; the U-shaped stone water-stop strip includes: a horizontal water-stop strip and an inner water-stop strip and an outer water-stop strip disposed on both sides of the bottom of the horizontal water-stop strip, the bottom of the inner water-stop strip being in contact with the stone layer of the shower room floor, and the outer water-stop strip being in contact with the tile layer of the dry area of ​​the bathroom.

[0015] Furthermore, the upper surface of the transverse water-blocking strip is provided with an inclined surface on the side near the shower room.

[0016] Furthermore, the tile layer in the dry area of ​​the bathroom extends to the bottom of the bathroom threshold stone at the end near the bathroom door opening.

[0017] The beneficial effects of this utility model are:

[0018] 1. This application installs a water-stop steel plate on the shower room floor to replace the traditional reinforced concrete water-stop sill.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The interior space of a bathroom is divided into a shower room and a dry area. The shower partition is where the shower room connects to the dry area, and the bathroom doorway is where the dry area connects to other living areas outside the bathroom.

[0029] like Figure 1-6As shown in some illustrative embodiments, a water-stopping threshold structure is provided to solve the problems of complexity, time-consuming construction, and easy leakage of traditional reinforced concrete structures. Specifically, it includes: a water-stopping steel plate 1, a waterproof layer 2, a bathroom threshold 3, a first structural adhesive layer 4, a second structural adhesive layer 5, a waterproof protective layer 6, a cement mortar leveling layer 7, a shower room floor stone layer 8, a bathroom dry area tile layer 9, an adhesive layer 10, and a U-shaped stone water-stopping strip 11.

[0030] The bottom and two sides of the waterstop steel plate 1 are bent outward to form a folded edge structure 101, so that the vertical section of the waterstop steel plate 1 is L-shaped and the horizontal section is U-shaped. Thus, after installation, the waterstop steel plate 1 can not only fit tightly with the floor slab and wall, but also form a physical water barrier through the folded edge structure 101, effectively preventing water from seeping in.

[0031] Water-stop steel plates 1 are installed at both the shower partition and the bathroom doorway. In the following text, the water-stop steel plate 1 located at the bathroom doorway will be referred to as the first water-stop steel plate 1A, and the water-stop steel plate 1 located at the shower partition will be referred to as the second water-stop steel plate 1B. The first water-stop steel plate 1A is used to prevent water from the bathroom floor from flowing out of the bathroom, and the second water-stop steel plate 1B is used to prevent water from the shower room from spreading to the dry area of ​​the bathroom.

[0032] The folded edge structure 101 of the second water-stop steel plate 1B bends and extends towards the dry area of ​​the bathroom, while the folded edge structure 101 of the first water-stop steel plate 1A bends and extends away from the bathroom, ensuring that the water flow is effectively blocked.

[0033] A bathroom threshold 3 is installed on the floor at the bathroom doorway, and an elongated groove 301 is formed on the lower surface of the bathroom threshold 3. The top of the first water-stop steel plate 1A is embedded in the elongated groove 301 and connected to the groove wall of the elongated groove 301 through the first structural adhesive layer 4. That is, the first structural adhesive layer 4 is filled between the outer surface of the top of the first water-stop steel plate 1A and the groove wall of the elongated groove 301, so that a firm and sealed connection is formed between the first water-stop steel plate 1A and the bathroom threshold 3. This not only fixes the first water-stop steel plate 1A, but also effectively prevents water from seeping out from under the doorway.

[0034] Waterproof layer 2 is applied to the bathroom floor, bathroom walls, and the surface of the second water-stop steel plate 1B, extending to the inner top of the first water-stop steel plate 1A and connecting with the first structural adhesive layer 4. Waterproof layer 2 is applied to the bathroom floor and walls, covering the surface of the water-stop steel plate at the shower partition. At the doorway, waterproof layer 2 extends to the inner top of the water-stop steel plate 1 and is tightly bonded to the first structural adhesive layer 4. This full-coverage design ensures effective waterproofing of the water-stop steel plate 1 itself and its connections.

[0035] A second structural adhesive layer 5 is installed between the bottom edge of the waterstop steel plate 1 and the floor slab, and between the side edge structures of the waterstop steel plate 1 and the wall. The second structural adhesive layer 5 not only helps to fix the position of the waterstop steel plate 1, but also enhances the sealing between the waterstop steel plate 1 and the bathroom floor and wall structure, preventing water from seeping through the joint gaps.

[0036] A waterproof protective layer 6 is provided on the surface of the waterproof layer 2 laid on the bathroom floor. The waterproof protective layer 6 is used to protect the waterproof layer 2 from damage by subsequent construction, such as laying tiles.

[0037] The cement mortar leveling layer 7 is set on the surface of the waterproof protective layer 6, and the cement mortar leveling layer 7 provides a smooth base for the subsequent finishing layer.

[0038] A stone veneer layer 8 is used to decorate the shower room floor. A tile layer 9 is used to decorate the dry area floor of the bathroom. An adhesive layer 10 is installed between the stone veneer layer 8 and the cement mortar leveling layer 7, and between the tile layer 9 and the cement mortar leveling layer 7 in the dry area of ​​the bathroom. This adhesive layer 10 bonds the stone and tile layers to the leveling layer, providing better bonding strength and flexibility.

[0039] The U-shaped stone water-blocking strip 11 is wrapped around the top of the second water-stop steel plate 1B by the mortar layer 10.

[0040] The U-shaped stone water-blocking strip 11 includes: a horizontal water-blocking strip 111 and an inner water-blocking strip 112 and an outer water-blocking strip 113 set on both sides of the bottom of the horizontal water-blocking strip 111. The bottom of the inner water-blocking strip 112 is attached to the stone layer 8 of the shower room floor, and the outer water-blocking strip 113 is attached to the tile layer 9 of the dry area of ​​the bathroom. The horizontal water-blocking strip 111 is located above the second water-stop steel plate 1B, forming a physical barrier to prevent water from flowing over the partition.

[0041] The upper surface of the horizontal water-blocking strip 111 has an inclined surface 114 on the side near the shower room to facilitate drainage and prevent water accumulation.

[0042] The dry area tile layer 9 of the bathroom extends into the bottom of the bathroom threshold 3 at the end near the bathroom door opening, further enhancing the sealing of the door opening.

[0043] For all joints of the finishing layers, especially key areas such as the inside corners of the U-shaped stone water-retaining strip 11 and the floor, and the inside corners of the threshold stone and the floor, use polyurea grout for sealing. Polyurea grout has excellent elasticity and waterproof performance, which can further improve the overall leak-proof effect and aesthetics.

[0044] The construction steps are as follows:

[0045] First, install the water-stop steel plate 1 at the shower partition and the bathroom door opening, and then bond and fix the folded structure 101 to the floor slab and wall through the second structural adhesive layer 5.

[0046] Then, after installing the water-stop steel plate 1 at the bathroom door opening, the bathroom threshold 3 is laid, and the top of the water-stop steel plate 1 is sealed and bonded to the bathroom threshold 3 using the elongated groove 301 and the first structural adhesive layer 4.

[0047] Then, round the inside corners of the ground, apply the waterproof layer 2, and ensure that it covers all the walls, floors and the water-stop steel plate 1 at the shower partition, and extends to the top inside of the water-stop steel plate 1 at the bathroom door opening, connecting with the first structural adhesive layer 4.

[0048] Then, lay the waterproof protective layer 6, the cement mortar leveling layer 7, and then use the putty layer 10 to lay the shower room floor stone layer 8, the bathroom dry area tile layer 9, and the U-shaped stone water-blocking strip 11.

[0049] Finally, seal all seams, especially key inside corners, with polyurea grout 12.

[0050] This application has the following advantages:

[0051] Simple construction and high efficiency: It eliminates the complex and time-consuming processes of traditional drilling and rebar installation, formwork, concrete pouring, and curing. During construction, it is only necessary to cut and install the prefabricated waterstop steel plate 1 and use structural adhesive to bond and fix it. The waterstop steel plate 1 is a prefabricated component, and the installation is relatively standardized, which reduces the technical requirements for workers, reduces human error, and the whole installation process is quick, shortening the construction cycle and thus improving the overall decoration efficiency.

[0052] Quality controllable and high reliability: The use of structural adhesive bonding ensures a strong and sealed connection between the waterstop steel plate 1 and the floor slab, wall, and bathroom threshold 3, avoiding the leakage risks caused by weak rebar installation, formwork displacement, and non-dense concrete in traditional methods. The arrangement of the waterproof layer 2 forms a complete, multi-layered waterproof system, improving the waterproof effect. Moreover, the steel plate itself is not easily deformed, and the folded edge design increases the physical water-blocking capacity, reducing weak points such as cracks and hollow areas that may occur in traditional concrete structures.

[0053] Excellent anti-leakage effect: The folded edge structure 101 of the water-stop steel plate, the embedded bonding of the long groove 301, the use of the U-shaped stone water-blocking strip 11, and the arrangement of the waterproof layer 2 together form an effective waterproof barrier, which is not easy to age or corrode, ensuring a long-term waterproof effect.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
