Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a waterproof structure of a toilet threshold stone. Background Art
[0002] At present, the common construction method for threshold stones is to set up waterproof layer, filling layer, waterproof adhesive, sealant, bonding layer and other processes, which requires high technical level of operators and is difficult to control quality. If the operation control is not appropriate, gaps and hollows are likely to appear between the processes, and the long-term water accumulation in the bathroom causes water and water vapor to seep out through weak points and penetrate into the walls and floors of the adjacent living room and rooms in the house where no waterproofing is set. When leak investigation and repair were carried out on the completed projects where the walls of the living room and rooms were damp and peeling, it was also found that this situation was mostly caused by the loose grouting or caulking under the threshold stone, and water penetrated through the gaps into the paving layer of the floor tiles in the living room and rooms. After long-term accumulation, the accumulated water in the paving layer of the floor tiles rose along the wall, causing the walls of the living room and rooms to become damp and peel.
[0003] CN112962798A discloses a waterproof structure and construction method for an indoor bathroom, which adopts a combined multi-layer waterproof structure to reduce joints exposed to wet areas and avoid the infiltration of water or water vapor. However, the water-stopping sill at the threshold stone in this patent is cast for the second time, and the lower part is embedded in the structural plate, which requires the structural plate to reserve a concave groove in advance. The size and lines of the concave groove are small, and it is not easy to control the molding quality. In addition, many decorations are constructed by later units, and the front and back cannot be effectively combined. In fact, such reservations are very few, and before the secondary casting of the water-stopping sill, the surface of the concave groove structural plate needs to be fully roughened, cleaned, and moistened to achieve good adhesion, otherwise gaps are likely to appear, causing the risk of water seepage; in addition, the waterproof layer of the bathroom does not extend to the walls and floors adjacent to the indoor dry area, the waterproof layer does not achieve the integrated encapsulation of the bathroom and the threshold stone, and the vertical direction of the L-shaped threshold does not completely encapsulate the water-stopping sill, which is easy to form a weak position.

[0029] The utility model will be further described below in conjunction with the accompanying drawings:
[0030] See also Figures 1 to 4 As shown, the present application provides a bathroom threshold stone waterproof structure 1, which includes a waterproof mortar water stop sill 11, a waterproof coating layer 12, a first adhesive layer 13 and a threshold stone 14, which are sequentially laid on the top of a structural plate 4 between a bathroom 2 and a room 3 from bottom to top; wherein the waterproof coating layer 12 includes a first part 121 laid on the upper surface and both side surfaces of the waterproof mortar water stop sill 11, a second part 122 formed by extending one end of the first part 121 toward the bathroom 2, and a third part 123 formed by extending the other end of the first part 121 toward the room 3; since the waterproof coating layer 12 extends into the bathroom 2 to form a waterproof layer of the bathroom, and at the same time, the waterproof mortar water stop sill 11 is turned up and then extended outward to the wall and ground of the dry area adjacent to the room 3, the waterproof coating layer 12 can achieve overall encapsulation of the bathroom and the threshold stone structure, which can better block water penetration, whether it is water on the floor of the bathroom or water that penetrates into the expanded clay, it will not penetrate through the threshold stone to the position of the indoor dry area, which more effectively improves the waterproofness of the bathroom threshold stone waterproof structure.
[0031] Specifically, in this embodiment, the waterproof coating layer 12 is a polymer cement waterproof coating with a thickness of 2 mm. The waterproof coating layer 12 extends from one side of the waterproof mortar water stop 11 toward the bathroom 2 to form a second part 122, and extends 500 mm from the other side of the waterproof mortar water stop 11 toward the room 3 and extends horizontally 200 mm on both sides of the threshold 5 to form a third part 123.
[0032] See also Figures 1 to 3 As shown, the cross-section of the threshold stone 14 is L-shaped, and the horizontal section 141 of the threshold stone is laid on the upper surface of the first adhesive layer 13, and the upper surface of the horizontal section 141 is flush with the indoor finished surface 31; the vertical section 142 of the threshold stone is fully pasted on the side of the waterproof mortar water stop 11 close to the bathroom 3 with polymer cement mortar, and the vertical section 142 extends to the bottom of the bathroom finished surface 21, and the bottom position of the vertical section 142 is lower than the lower surface of the waterproof mortar water stop 11, so that the secondary decoration structure at the threshold stone is overall encapsulated.
[0033] As a preference, see Figure 3As shown, the threshold stone 14 is formed by splicing two pieces of stone, and the joint 143 of the two pieces of stone is located in the horizontal section 141, so that the vertical section 142 is a whole without a gap, so as to avoid the risk of water seepage at the joint 143; the threshold stone 14 is made of two pieces of stone glued together with marble glue, which is easy to process and has strong practicality, which not only solves the problem of high processing cost of using a whole piece of stone, but also reduces the processing difficulty of the L-shaped threshold stone.
[0034] Specifically, in this embodiment, the thickness of the waterproof mortar water stop 11 is 20 mm; a waterproof coating layer 12 with a thickness of 2 mm is laid on the waterproof mortar water stop 11; a first adhesive layer 13 with a thickness of 8 mm is laid on the waterproof coating layer 12, and the first adhesive layer 13 is polymer cement mortar. Since the L-shaped threshold stone adopts 8 mm thick polymer cement mortar to be filled with thin paste and grouting, it is not easy to be hollow; the thickness of the horizontal section 141 of the threshold stone 14 is 20 mm, and the upper surface of the horizontal section 141 is flush with the indoor finished surface 31 ; The thickness of the vertical section 141 is 10 mm. Since the thickness of the bathroom wall tiles is 10 mm, the use of a threshold stone with a vertical section thickness of 10 mm is conducive to improving the flatness of the wall near the threshold stone; the length of the vertical section 141 is 70 mm, and the bottom position of the vertical section is 20 mm lower than the lower surface of the waterproof mortar water stop 11, which can better block water penetration; further, a 3*3 mm fine grinding edge 144 is provided on the top of the vertical section near the bathroom 3, and the grinding edge is set to eliminate sharp edges and improve safety.
[0035] In some other embodiments, the upper surface of the threshold stone horizontal section 141 is configured as follows: Figure 4 The slope structure shown has an upper surface whose side close to the interior 3 is flush with the interior finish surface 31 , and an upper surface whose side close to the bathroom 2 is flush with the bathroom finish surface 21 , so as to form a barrier-free threshold.

[0051] ⑹ Laying of L-shaped threshold stone
[0052] The portion of the L-shaped threshold stone with a thickness of 20 mm and a length of 105 mm is horizontally laid above the waterproof mortar water stop 11, and its upper surface is flush with the indoor finished surface 31; the portion with a thickness of 10 mm and a length of 70 mm is vertically laid on the side of the waterproof mortar water stop 11 close to the bathroom; the bottom of the vertical section of the L-shaped threshold stone abuts against the upper surface of the cement mortar protective layer 26; the L-shaped threshold stone is laid by pasting and grouting with polymer cement mortar;
[0053] ⑺ Laying of the remaining structural layers in the bathroom
[0054] On top of the cement mortar protective layer 26, lay the following in order from bottom to top:
[0055] M15 cement mortar bonding layer 27 with a thickness of 35 mm;
[0056] A polymer cement mortar adhesive layer 28 with a thickness of 5 mm;

[0059] The bathroom threshold stone waterproof structure provided by the present application adopts an L-shaped threshold stone, and the vertical section of the threshold stone is extended to below the finished surface of the bathroom and lower than the lower surface of the waterproof mortar water stop sill, so that the secondary decoration structure at the threshold stone is completely encapsulated; at the same time, a waterproof coating layer is laid on the waterproof mortar water stop sill, and the waterproof coating layer is extended into the bathroom to form a waterproof layer of the bathroom, and then the hump of the waterproof mortar water stop sill is turned up and extended outward to the wall and floor adjacent to the indoor dry area, so that the waterproof coating layer can completely encapsulate the bathroom and the threshold stone structure, which can better block water penetration. No matter it is water on the floor of the bathroom or water that seeps into the expanded clay, it will not seep out through the threshold stone to the indoor dry area, which more effectively improves the waterproofness of the bathroom threshold stone waterproof structure.
[0060] Since the bathroom threshold stone waterproof structure provided in this application is constructed above the structural plate, there is no need to reserve a recessed groove on the structural plate in advance, which reduces the difficulty of construction; the laying of the L-shaped threshold stone in this application is carried out simultaneously with the laying in the bathroom, which can make the vertical section of the L-shaped threshold stone better fit with the finished surface of the bathroom, further reducing the risk of water seepage, and the construction operation is convenient, practical, and the quality is easy to control.
