Description

Technical Field

[0001] The utility model relates to the technical field of swimming pool waterproof structures, in particular to an exposed swimming pool waterproof structure. Background Art

[0002] As a special water container, swimming pools have extremely strict requirements on waterproof materials and construction. Although the waterproof materials used in traditional swimming pool construction, such as cement-based waterproof coatings and waterproof membranes, meet the waterproof requirements to a certain extent, they are insufficient in terms of durability, adhesion, chemical corrosion resistance, elasticity, environmental protection, and construction convenience, and cannot fully meet the waterproof requirements of modern high-standard swimming pools.

[0003] In order to ensure the aesthetics of traditional swimming pools, painted tiles or paint are usually used. Painted tiles are prone to falling off after long-term immersion, and paint paintings are easily repelled by waterproof materials, causing stratification and water seepage in the waterproof layer. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an exposed waterproof structure for a swimming pool.

[0005] The technical solution adopted by the utility model to solve the technical problem is: an exposed waterproof structure of a swimming pool, including an anti-corrosion concrete layer, a putty layer, a closed base surface layer, a polyurea resin waterproof layer and a polyurea painted topcoat layer, which are compositely formed on the swimming pool base layer from bottom to top, a groove is opened at the swimming pool pipe, the swimming pool pipe outlet is lower than the groove mouth, and a polyurea resin waterproof layer and a silicone sealant are arranged in sequence at the groove.

[0006] Compared with traditional waterproof materials, such as waterproof membranes, the exposed waterproof structure of the swimming pool uses polyurea to form a continuous and seamless waterproof membrane with excellent weather resistance. It can effectively resist the invasion of natural conditions such as ultraviolet rays and extreme temperature changes, enhance the overall waterproof performance and stability, and its durability far exceeds that of general traditional waterproof materials, and can provide long-lasting waterproof protection.

[0007] In addition, polyurea waterproof coatings can adhere well to a variety of substrates, have good chemical resistance, can withstand the erosion of swimming pool disinfectants and cleaning chemicals, and maintain stable physical and chemical properties.

[0008] In addition, one of the notable characteristics of polyurea waterproofing materials is its ability to cure quickly, usually within seconds to minutes to form a membrane, which greatly shortens the construction time and allows the swimming pool to be put into use soon after construction.

[0009] At the same time, polyurea products are environmentally friendly materials, containing low or no volatile organic compounds (VOCs), meeting environmental protection requirements. The use of polyurea topcoat for painting and seamless integration with the polyurea waterproof layer achieves waterproof functionality. It can provide a variety of colors and textures to enhance the visual effect of the swimming pool.

[0010] As a further improvement of the utility model: the polyurea resin waterproof layer at the inner side of the swimming pool is extended to the outer interface of the ditch, and silicone sealant is also provided outside the polyurea resin waterproof layer at the drainage ditch.

[0011] As a further improvement of the utility model: the putty layer adopts a penetrating water-based epoxy resin coating.

[0012] As a further improvement of the utility model: the closed base surface layer is a high-permeability polyurethane primer, and the coating thickness is 0.2mm-0.5mm.

[0013] As a further improvement of the utility model: a special waterproof primer is applied between the closed base surface layer and the polyurea resin waterproof layer, and the coating thickness is 0.2mm-0.5mm.

[0014] As a further improvement of the utility model: the spraying thickness of the polyurea resin waterproof layer is 2mm-4mm.

[0015] As a further improvement of the utility model: the spraying thickness of the polyurea painted topcoat layer is 0.2mm-1mm.

[0016] As a further improvement of the utility model: the anti-corrosion concrete layer adopts C35 concrete with a thickness of 20mm-25mm.

[0017] As a further improvement of the utility model: the special waterproof primer is epoxy resin primer or polyurethane primer.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The exposed waterproof structure of the swimming pool is coated with putty on the anti-corrosion concrete layer to make the surface of the base layer smooth, which can effectively reduce problems such as hollowing and cracking during the subsequent construction of the polyurea waterproof layer, ensuring the continuity and integrity of the waterproof layer. A closed base surface layer is applied on the putty layer to effectively seal the base surface and reduce the intrusion of moisture and other foreign substances that may affect the performance of the polyurea coating. Grooves are opened on the overall base surface and at the pipe openings to spray the polyurea resin waterproof layer to enhance the waterproof effect. The grooves are also filled with silicone sealant to enhance the waterproof performance of the swimming pool's prone to water seepage. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to solve the technical problems in the prior art, the utility model is further described in conjunction with the accompanying drawings and embodiments:

[0027] like Figure 1 to Figure 2 As shown, the present embodiment discloses an exposed waterproof structure 100 for a swimming pool, comprising an anti-corrosion concrete layer 1, a putty layer 2, a closed base layer 3, a polyurea resin waterproof layer 5 and a polyurea painted topcoat layer 6 which are compositely formed from bottom to top on a swimming pool base layer, a groove is provided at the swimming pool pipe, the outlet of the swimming pool pipe is lower than the groove mouth, and a polyurea resin waterproof layer 5 and a silicone sealant 7 are provided in sequence at the groove.

[0028] In this embodiment, putty is applied on the anti-corrosion concrete layer 1 to level the surface of the base layer and ensure the continuity and integrity of the waterproof layer. A closed base surface layer 3 is further applied on the putty layer 2 to effectively seal the base surface and reduce the intrusion of moisture and other external substances that may affect the performance of the polyurea coating. Grooves are then opened on the overall base surface and at the pipe openings to spray a polyurea resin waterproof layer 5 to enhance the waterproof effect. Silicone sealant 7 is also filled in the grooves to enhance the waterproof performance of locations where water is prone to seepage in the swimming pool.

[0029] Compared with the existing swimming pools that use painted tiles or paint paintings, painted tiles are prone to falling off after long-term immersion, and paint paintings are easily repelled by waterproof materials, resulting in stratification and water seepage in the waterproof layer. The polyurea painted material used in this embodiment is the same material as the exposed polyurea resin waterproof layer 5, which can be well blended to form a skin-like waterproof effect, which takes into account both aesthetics and waterproof functionality.

[0030] Sealing and waterproofing treatment for wall-penetrating pipes: For wall-penetrating pipes made of PE material, since PE material is an inert material in chemical principles, ordinary materials are incompatible with it and cannot be well bonded with it. In addition, PE pipes have good elasticity and will be affected by water pressure during use. They will frequently shrink, expand and deform, causing the outer sealing material to easily delaminate and leak.

[0031] For this purpose, a 30*30mm groove is reserved around all the pipes that penetrate the wall of the pool. The pipes that penetrate the wall need to be polished and cut to 10mm below the side wall. Regardless of the material, the finished product after treatment shall not protrude from the wall. Then apply the corresponding polyurea resin waterproof layer 5, and then fill the surrounding with silicone sealant 7. Finally, the surrounding of the pipe mouth is treated to make the color of the pipe mouth consistent with the surrounding.

[0032] Pool wall pipe sealing and waterproofing process:

[0033] ①Clean the reserved groove→②Grind and cut the pipe to 10mm below the side wall→③Apply the corresponding polyurea waterproof layer→④Fill with silicone sealant 7→⑤Process the pipe mouth.

[0034] As a preferred embodiment, the anti-corrosion concrete layer 1 is made of C35 concrete with a thickness of 20mm-25mm.

[0035] The swimming pool environment usually involves factors such as continuous water contact, the use of chemical disinfectants (such as chlorine), and possible temperature fluctuations. The application of anti-corrosion concrete in swimming pools can significantly improve the durability and safety of swimming pools and ensure stability and waterproofness during long-term use.

[0036] During the construction process, ensure that the base layer is flat, clean, free of impurities and loose materials. If it is a dry base layer, it needs to be moistened first, but there must be no water accumulation. Locate the drainage point position, edge position and other key points on the base layer to guide slope finding, confirm the elevation of each measuring point, ensure that the slope meets the design requirements and tilts toward the swimming pool drain. After the anti-corrosion concrete construction is completed, proper maintenance is required, such as covering with plastic film, wet quilts, etc., to maintain a certain humidity to prevent cracks and ensure strength. The maintenance time is adjusted according to local environmental conditions and actual needs, usually no less than 7 days.

[0037] After grinding off the anti-corrosion concrete, the base surface, such as formwork joints, honeycombed surfaces, construction joints, etc., must present a solid foundation without slurry, completely exposing the concrete pores, repairing the inner corners into a 50R arc, and cutting and grinding the outer corners into rounded corners.

[0038] As a preferred embodiment, the polyurea resin waterproof layer 5 at the inner side of the swimming pool is extended to the outer interface of the ditch, and a silicone sealant 7 is also provided outside the polyurea resin waterproof layer 5 at the drainage ditch.

[0039] The drainage ditch on the inner side of the swimming pool is closed: the range of the polyurea resin waterproof layer 5 is made to the outer interface of the ditch cover, and the sealant 7 is used to bond and seal.

[0040] Closing of the outer wall of the swimming pool: The polyurea resin waterproof layer 5 is made to the top surface of the wall.

[0041] More preferably, silicone sealant 7 is used.

[0042] As a preferred embodiment, the putty layer 2 adopts a penetrating water-based epoxy resin coating.

[0043] Apply the putty twice until the holes are completely filled. The putty used should be considered to have good adhesion to the subsequent polyurea layer and should be thickly applied without sagging on the wall surface of the pool. After the base surface is dry, lightly polish it again to make the surface of the base smooth. This can effectively reduce hollowing and cracking problems during the construction of the polyurea waterproof layer, improve the adhesion of the sprayed polyurea, ensure the continuity and integrity of the waterproof layer, and thus enhance the waterproof effect.

[0044] As a preferred embodiment, the closed base surface layer 3 is a high-permeability polyurethane primer, and the coating thickness is 0.2mm-0.5mm. More preferably, the coating thickness is 0.2mm.

[0045] When applying high-penetration polyurethane primer, the air humidity is lower than 85% and the moisture content of the base surface is less than 7%. High-penetration primer can penetrate into the micropores of the base material to ensure that the waterproof layer can effectively protect the structure in a long-term manner. By filling the pores and cracks on the surface of the base, high-penetration primer can effectively seal the base surface and reduce the intrusion of moisture and other foreign substances (such as grease, dust, etc.) that may affect the performance of the polyurea coating.

[0046] As a preferred embodiment, a waterproof primer 4 is applied between the closed base surface layer 3 and the polyurea resin waterproof layer 5, and the thickness of the primer 4 is 0.2 mm to 0.5 mm. More preferably, the thickness of the primer 4 is 0.2 mm.

[0047] The adhesive that increases the adhesion between the sprayed polyurea and the substrate uses a special waterproof primer 4. When spraying polyurea, a surfactant is required to enhance the adhesion. The special waterproof primer can improve the adhesion between the polyurea coating and the base layer, forming a stable anchoring layer, ensuring that the polyurea coating can adhere firmly to the base layer, preventing the coating from falling off or peeling off, and improving the bonding performance between the polyurea coating and the base layer.

[0048] As a preferred embodiment, the spraying thickness of the polyurea resin waterproof layer 5 is 2mm-4mm. More preferably, the spraying thickness of the polyurea resin waterproof layer 5 is 3mm.

[0049] During construction, please use an ambient temperature of 10°C or higher, a base surface temperature of 3°C or higher than the dew point, and an ambient humidity of less than 85% to ensure good film formation. Construction should be carried out in sunny weather, and try to avoid humid weather and harsh weather conditions such as morning dew.

[0050] The polyurea resin waterproof layer 5 has the following advantages:

[0051] (1) Polyurea has excellent waterproof properties and can effectively prevent water penetration and protect the swimming pool structure from water damage. The polyurea coating forms a seamless protective layer that can thoroughly cover every corner of the base layer, including complex parts such as corners and edges of the swimming pool, thereby achieving a full range of waterproof effects.

[0052] (2) Polyurea waterproof coating cures quickly, usually within a few seconds to a few minutes after construction, which greatly shortens the construction period and speeds up the commissioning of the swimming pool.

[0053] (3) The polyurea coating has high elasticity and elongation, and can adapt to slight deformations of the base layer without cracking. It can cope with the effects of temperature changes, foundation settlement, etc. and maintain the stability of its waterproof performance.

[0054] (4) The polyurea waterproof coating has excellent chemical stability and can withstand chemicals such as disinfectants added to swimming pool water, maintaining its waterproof performance.

[0055] (5) Polyurea coating has excellent weather resistance and aging resistance, and can maintain long-term waterproof performance even in the sun, rain or continuous humidity environment.

[0056] (6) Modern polyurea materials usually meet environmental protection requirements and are safe for the environment and human body. In places such as swimming pools where people come into direct contact with water.

[0057] As a preferred embodiment, the spraying thickness of the polyurea painted topcoat layer 6 is 0.2 mm-1 mm.

[0058] Before the construction of manual polyurea topcoat, the polyurea waterproof layer should be lightly polished (to polish off the paint mist and surface particles generated by spraying), and applied thinly several times to ensure that the paint film is cured, does not sag, and has a smooth and beautiful surface effect.

[0059] Manual polyurea coating should be even and tightly sealed, with at least 3 coats, and the film thickness should be guaranteed to be 0.5mm, without sagging or missing. Use different colors of polyurea weather-resistant topcoat for manual painting, and beautify and paint according to the design patterns and colors to meet the needs of different design aesthetics.

[0060] As a preferred embodiment, the special waterproof primer 4 is epoxy resin primer or polyurethane primer.

[0063] The main functions of the utility model: the polyurea resin waterproof layer used in the exposed waterproof structure of the swimming pool is a seamless and strong waterproof layer with good weather resistance, durability, adhesion, chemical resistance and environmental protection, and also has the function of rapid curing.

[0064] In summary, after reading the utility model document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the utility model without creative mental labor, which all fall within the scope of protection of the utility model.
