Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bathroom waterproofing, specifically to a bathroom corner waterproofing system. Background Technology
[0002] Waterproofing the corners of a bathroom is a crucial step in bathroom renovation. Before construction, it's essential to thoroughly clean any remaining debris and cement residue from the corners, ensuring the surface is clean, free of oil and dust. Before applying the waterproof coating, the substrate should be moistened with water to prevent uneven application or cracking due to an overly dry substrate. When applying the waterproof coating, follow the principle of "thin coats, multiple layers," ensuring each layer is evenly applied without any missed spots or thin coats. Currently, to enhance waterproofing, a waterproof fabric is often added between the waterproof layers, a process known as "two coats and one fabric." This involves laying a layer of polyester fiber non-woven fabric between two coats of waterproof coating. The seal between the waterproof fabric and the waterproof layer determines the waterproofing level. Traditional waterproof fabrics are bonded with adhesives, but over time, the bonding strength decreases, leading to gaps and separation of the surface waterproof layer. Relying solely on the inner waterproof layer results in a low waterproofing level, necessitating improvement. Therefore, we propose a bathroom corner waterproofing system. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0019] like Figure 1-3As shown, this utility model discloses a bathroom corner waterproofing system, including a corner wall 1. The corner wall 1 is provided with a waterproof layer A8, a waterproof cloth 2, a compacted sealing layer and a waterproof layer B9 from the inside to the outside. The compacted sealing layer includes a right-angle pressure plate 6, side pressure plates A5 and B7 distributed on both sides of the right-angle pressure plate 6. The right-angle pressure plate 6 has grooves A12 on its two right-angled ends away from the waterproof cloth 2. The side pressure plates A5 and B7 have grooves B10 near the right angle of the corner wall 1. The grooves B10 of the side pressure plates A5 and B7 are respectively engaged with the grooves A12 on the two right-angled ends of the right-angle pressure plate 6. Anchor bolts 4 are pre-embedded on the two right-angled ends of the corner wall 1. The anchor bolts 4 pass through the waterproof cloth 2 and the compacted sealing layer in sequence. The end of the anchor bolt 4 that passes through the compacted sealing layer is threaded with a fastening nut 3.
[0020] Example 1: Anchor bolts 4 are pre-installed on the inside corner wall 1. Then, a first waterproof layer A8 is applied to the surface of the inside corner wall 1. The area around the anchor bolts 4 also needs to be coated with waterproof layer A8. After the waterproof layer A8 has solidified, a waterproof cloth 2 is laid on its surface. The waterproof cloth 2 is made of polyester fiber non-woven fabric. The parts where the anchor bolts 4 penetrate the waterproof cloth 2 need to be re-applied with waterproof material. Then, the right-angle pressure plate 6, side pressure plate A5, and side pressure plate B7 are installed in sequence. The total thickness of the right-angle pressure plate 6, side pressure plate A5, and side pressure plate B7 is 10mm. The depth of grooves A12 and B10 is 5mm. As the fastening nut 3 is tightened, the side pressure plates A5 and B7 can press the right angle pressure plate 6 tightly against the waterproof cloth 2. At the same time, the side pressure plates A5 and B7 can also press the waterproof cloth 2 tightly against the waterproof cloth 2. Finally, the last layer of waterproof layer B9 is applied to the outer surface of the right angle pressure plate 6, side pressure plate A5, and side pressure plate B7. The addition of the pressure plate structure improves the tightness of the waterproof cloth against the inside corner wall. The pressure plate structure can also protect the waterproof layer at the inside corner, greatly improving the waterproof level.
[0021] In the preferred technical solution, the thickness of side pressure plate A5 and side pressure plate B7 is the same as the thickness of right angle pressure plate 6, and the depth of groove A12 and groove B10 is half the total thickness of right angle pressure plate 6, side pressure plate A5 and side pressure plate B7, so as to avoid the pressure plate thickness being too large and affecting the subsequent tile laying process.
[0022] In the preferred technical solution, sealing strips A11 are fixedly installed on the end faces of side pressure plates A5 and B7 facing the waterproof cloth 2, and sealing strips B13 are fixedly installed on the end faces of right-angle pressure plates 6. Both sealing strips A11 and B13 are rectangular closed rubber strips. The sealing strips are pressed and adhered to the surface of the waterproof cloth 2, which greatly improves the sealing performance between the waterproof cloth 2 and the surface of the wall at the inside corner 1.
[0023] In summary, this embodiment provides a process for using two layers of waterproofing with an additional waterproof cloth 2 in between for the inside corner wall, which improves the waterproofing performance. In addition, the addition of a pressure plate structure improves the tightness of the fit between the waterproof cloth and the inside corner wall. The pressure plate structure uses bolts to fasten and press the waterproof cloth together to improve the sealing between the waterproof cloth and the inside corner wall. The pressure plate structure can also protect the waterproof layer at the inside corner, greatly improving the waterproofing level.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
