Description

Technical Field

[0001] The present application belongs to the field of building floor waterproofing, and specifically relates to a shower area waterproof sunken bathroom floor structure. Background Art

[0002] In the process of residential decoration, in order to improve the comfort of the bathroom, the bathroom is usually divided into two parts: a dry area and a wet area. However, in the prior art, the bathroom structure has two problems:

[0003] Firstly, in order to prevent bathing water from flowing onto the dry floor, a glass partition is often installed between the dry and wet areas. A water retaining bar is provided under the partition, which is about 20 to 50 mm higher than the brick floor. For special groups such as the elderly, children and people with mobility difficulties, it is very inconvenient to enter and exit the bathing area. They may be easily tripped by protruding facilities, posing a safety hazard.

[0004] Secondly, the waterproof layer of the dry area floor is on the same horizontal plane as the waterproof layer of the wet area floor. Sometimes the waterproof layer of the dry area floor is lower than that of the wet area floor, and the bonding layer of the floor tiles is connected to the cement mortar layer as a whole. Since cement mortar is a porous and water-permeable material, water on the ground can easily penetrate into the cement mortar bonding layer of the wet area floor through the joints between the floor tiles, and then penetrate into the cement mortar layer of the dry area floor. Over time, the cement mortar layer of the dry area floor will be filled with moisture, which not only makes the dry area floor cold and damp, and the user experience is poor, but also the moisture is likely to seep out through the surrounding walls and door openings, causing water seepage and leakage in the bathroom, destroying the durability of the building structure, and affecting people's production and life;

[0005] Furthermore, in the prior art, a utility model patent with announcement number CN219100605U discloses a bathroom floor structure with a sunken shower area. The problem is that the bathroom partition is directly installed on the floor of the wet area, which is not conducive to the full drainage of condensation water on the bathroom partition wall. The water discharged from the dry area to the wet area is also easy to accumulate at the bottom of the partition, which is not conducive to the cleaning and maintenance of this area. In addition, the partition is directly installed on the finishing layer, which requires high construction accuracy and is difficult to construct.

[0006] Therefore, there is an urgent need to propose a waterproof sunken bathroom floor structure in the shower area, which can improve the drainage capacity of the bathroom floor and is easy to clean. Utility Model Content
