Abstract
Description
Technical Field
[0001] This utility model relates to the field of threshold stone installation technology, specifically to a waterproof threshold stone installation structure for bathrooms. Background Technology
[0002] Threshold stones are used to separate areas of different materials or functions. They are typically installed between the kitchen and living room, or between the bathroom and living room, to create a smooth transition. Threshold stones can prevent floorboards from buckling, prevent water from the bathroom or kitchen from flowing into the living room, and also serve as a moisture barrier.
[0003] Because bathrooms use water frequently and in large quantities, water seepage is a common problem. Therefore, bathroom waterproofing is always an important part of the renovation process. Current waterproofing techniques typically involve installing a threshold stone at the junction of the bathroom and the interior, slightly higher than the bathroom floor, to prevent water from seeping into the interior. A sealant is then applied to the junction of the threshold stone and the bathroom floor. However, in actual use, we have found that the threshold stone's waterproofing effectiveness is significantly reduced when faced with large amounts of water accumulation in a short period and prolonged water seepage.

[0021] Example 1
[0022] refer to Figures 1-2 This embodiment provides a waterproof threshold stone paving structure for bathrooms, the purpose of which is to solve the problem of poor seepage prevention effect of existing threshold stone paving structures. The specific structure of this embodiment will be described in detail below.
[0023] A waterproof threshold stone paving structure for a bathroom includes a threshold stone 1, a first waterproof coating, a second waterproof coating, a supporting beam 3, a cement mortar base layer 4, and a cement mortar leveling layer 5.
[0024] Among them, the first waterproof coating is laid on the base ground 6, the cement mortar base layer 4 is laid on the first waterproof coating, the support beam 3 is laid on the cement mortar base layer 4, the cement mortar leveling layer 5 is laid on the support beam 3, and the threshold stone 1 is laid on the cement mortar leveling layer 5.
[0025] Specifically, a second waterproof coating is provided on both sides of the first waterproof coating, the supporting beam 3, the cement mortar base layer 4, and the cement mortar leveling layer 5.
[0026] In this embodiment, a first waterproof coating and a second waterproof coating are respectively provided below and on both sides of the threshold stone paving structure. The double waterproof structure improves the seepage prevention effect of the threshold stone paving structure, thereby enhancing the overall waterproof performance of the threshold stone paving structure.
[0027] Specifically, the support platform 3 includes a support platform 31 and multiple support beams 32 laid on the support platform 31; the support platform 31 and the multiple support beams 32 are connected by an adhesive. The two sides of the support platform 31 are inclined.
[0028] In this embodiment, the adhesive includes, but is not limited to, MS sealant. MS sealant achieves leveling by adjusting the thickness, enabling fast and accurate installation, improving construction efficiency and quality. Thus, the adhesive enables preliminary bonding between the support platform 31 and the multiple support beams 32. Furthermore, the multiple support beams 32 support the threshold stone 1, facilitating the adjustment of the height of the threshold stone 1 to adjust the fit between the two sides. One side of the threshold stone 1 is flush with the living room floor, while the other side is higher than the kitchen or bathroom floor.
[0029] Meanwhile, the two sides of the support platform 31 are inclined, and the upper surface of the support platform 31 is lower than the lower surface of the finished floor tile in the kitchen or bathroom, while the lower surface is higher than the upper surface of the cement mortar bonding layer, thus forming a physical water barrier to prevent water vapor penetration and further improve the seepage prevention effect of the threshold stone paving structure.
[0030] Specifically, the first waterproof coating includes a first moisture-proof layer 7 disposed between the cement mortar base layer 4 and the foundation ground 6, and a first waterproof layer 2 disposed between the first moisture-proof layer 7 and the cement mortar base layer 4.
[0031] Specifically, the second waterproof coating includes a second moisture-proof layer 8 disposed on both sides of the first waterproof coating, the supporting beam 3, the cement mortar base layer 4, and the cement mortar leveling layer 5. A second waterproof layer 9 is disposed on the surface of the second moisture-proof layer 8.
[0032] In this embodiment, the first moisture-proof layer 7 and the second moisture-proof layer 8 are made of moisture-proof coating or moisture-proof pad. The moisture-proof coating can be waterproof, etc., and the first waterproof layer 2 and the second waterproof layer 9 are made of waterproof coating.
[0033] Optionally, the second waterproof coating can be integrated with the waterproofing of the kitchen or bathroom to improve the consistency of waterproofing inside the kitchen or bathroom, enhance the waterproofing effect inside the kitchen or bathroom, and improve the seepage prevention and waterproofing performance of the threshold stone paving structure.
[0034] Specifically, one side of the threshold stone 1 is chamfered. The chamfered end of the upper surface of the threshold stone 1 near the kitchen or bathroom softens the transition to the kitchen or bathroom floor tiles.
[0035] Specifically, extension ears 11 are provided on both the left and right sides of the threshold stone 1. The extension ears 11 extend to both sides of the door wall, which can improve the reliability of the connection with the door wall.
[0036] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
