Description

Technical Field

[0001] The utility model relates to a waterproof balcony. Background Art

[0002] In the architectural design of our country, balcony waterproofing has always been an important but often overlooked issue. The existing technology has relatively low waterproofing requirements for the design of ordinary balconies (balconies without water faucets and open corridor floors) and cold-bridge-proof ordinary balconies (balconies without water faucets and open corridor floors). The standard atlas usually only puts forward waterproofing structure requirements for balconies with water distribution points.

[0003] There are a large number of open balconies in residential buildings in the southern regions of our country. Due to the large amount of rainfall and humid climate in this region, the deficiency of waterproofing design in the existing technology results in relatively low overall waterproofing performance of balconies, which is prone to leakage problems. Similarly, in the northern regions, for open corridors, due to the need to set up cold-bridge-proof insulation layers, if the waterproof layer is not set up, the performance of the insulation layer will be significantly reduced, and even the insulation layer will be damaged.

[0004] Traditional waterproofing methods, such as adding waterproof agents to cement mortar, although they can provide a certain degree of waterproofing effect, cement mortar is a brittle material, which has strict requirements for the designed thickness, and is prone to aging and cracking after being put into use, and the waterproofing effect rapidly decreases over time, shortening the effective service life of the waterproofing work. These defects often lead to complaints from users and frequent repairs in actual use, increasing the maintenance cost. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a waterproof balcony with improved waterproofing performance and service life.

[0006] The purpose of the utility model is realized as follows:

[0007] A waterproof balcony comprises a cast-in-place reinforced concrete slab, on which a 2-mm-thick FDS cement-based penetrating crystalline waterproof coating and a 10-mm-thick anti-slip floor tile are sequentially arranged from bottom to top;

[0008] The FDS cement-based penetrating crystalline waterproof coating is coated on the cast-in-place reinforced concrete slab, and around the cast-in-place reinforced concrete slab, the waterproof coating is extended upward from the highest point of the ground and smeared to a height of 250 mm;

[0009] The 10-mm-thick anti-slip floor tile is laid on the cast-in-place reinforced concrete slab and is located above the FDS cement-based penetrating crystalline waterproof coating.

[0010] By applying a 2-mm-thick FDS cementitious capillary crystalline waterproof coating on the cast-in-place reinforced concrete slab and extending the waterproof coating 250 mm high around the perimeter, water penetration into the concrete slab is effectively prevented, forming a perfect waterproof barrier. Especially in the rainy and humid southern regions and the cold and dry northern regions, the waterproof performance of the balcony can be significantly improved.

[0011] The construction method of cementitious capillary crystalline waterproof materials is simple. No complex surface treatment is required. The surface does not need to be flat and dry. It only needs to be mixed into concrete or mortar in proportion, and then poured according to ordinary concrete pouring or mortar technology after stirring, reducing the construction process, and lowering the construction difficulty and cost.

[0012] The waterproof structure layer is simple. Compared with traditional waterproof practices, it saves material and labor costs. At the same time, it can reduce the construction period by 5 - 15 days, improve the construction efficiency, and lower the overall project cost.

[0013] The FDS cementitious capillary crystalline waterproof coating can form a self-waterproof structure in concrete or mortar, enhancing the compressive strength of concrete or mortar. When encountering water, it can self-heal micro-cracks less than 0.4 mm, extend the service life of the waterproof layer, and reduce the frequency and cost of later maintenance.

[0014] 10-mm-thick anti-slip floor tiles are used and laid above the waterproof coating to increase the safety of the balcony and prevent slipping accidents, especially suitable for open balconies and corridors in the rainy southern regions and the cold northern regions.

[0015] The balcony surface layer adopts the floor tile reverse casting process, canceling the cement mortar bonding layer. The floor tiles are prefabricated in the factory and integrally formed with the balcony structure. Only the prefabricated components need to be installed on-site, reducing the on-site floor tile laying workload, improving the construction efficiency, and ensuring the laying quality of the floor tiles.

[0016] The waterproof balcony is not only suitable for the rainy and humid climate conditions in the south, but also can play excellent waterproof and thermal insulation effects in the cold and dry environment in the north, solving the problem that the performance of the thermal insulation layer decreases due to the setting of the thermal insulation layer but no waterproof layer in the open corridor to prevent cold bridges.

[0017] The object of the present utility model can also be solved by the following technical measures:

[0018] Further, the 10-mm-thick anti-slip floor tiles are laid on the cast-in-place reinforced concrete slab by the floor tile reverse casting process, and the cast-in-place reinforced concrete slab is provided with a structural slab slope, and the drainage slope is 1%.

[0019] The cast-in-place reinforced concrete slab is provided with a drainage slope, enabling rainwater or other liquids to drain quickly, preventing water from accumulating on the balcony surface, thereby reducing the leakage risk and slipping hazard caused by waterlogging. The design of the drainage slope ensures the long-term dryness and safety of the balcony, further enhancing the service life and waterproof effect of the balcony.

[0020] The process of inverting floor tiles can be prefabricated in the factory, reducing the complexity and workload of on-site construction. At the same time, the cast-in-place reinforced concrete slab with a drainage slope can also be formed in one go during the pouring process, simplifying the construction process, shortening the construction period, and reducing the construction cost.

[0021] Adopting the anti-slip floor tile inverting design and the drainage slope design not only improves the safety and waterproof performance of the balcony, but also reduces the frequency and cost of later maintenance, providing a more reliable and comfortable user experience, meeting the high requirements of modern residences for safety and convenience.

[0022] Furthermore, there is a dry-mix mortar with a thickness of 20 mm and a ratio of 1:4 between the FDS cement-based penetrating crystalline waterproof coating and the anti-slip floor tiles. A layer of neat cement is sprinkled on the surface of the dry-mix mortar. The anti-slip floor tiles are laid on the cast-in-place reinforced concrete slab and above the FDS cement-based penetrating crystalline waterproof coating. The gap between the anti-slip floor tiles is 5 - 8 mm, and the gap is filled with jointing agent. The cast-in-place reinforced concrete slab is provided with a structural slab slope, and the slope of the drainage slope is 1%.

[0023] Setting a dry-mix mortar with a thickness of 20 mm and a ratio of 1:4 between the FDS cement-based penetrating crystalline waterproof coating and the anti-slip floor tiles, and sprinkling a layer of neat cement on the surface of the dry-mix mortar increases the bonding force between the waterproof layer and the floor tiles, ensures the stable laying of the floor tiles, avoids the loosening or falling off of the floor tiles, and improves the durability and reliability of the overall structure.

[0024] The cast-in-place reinforced concrete slab is provided with a structural slab slope ， The slope of the drainage slope is 1%, effectively promoting the rapid drainage of water on the balcony surface, avoiding waterlogging, reducing the leakage risk caused by waterlogging, protecting the service life of the waterproof layer and the floor tiles, and improving the overall waterproof performance of the balcony.

[0025] The anti-slip floor tiles are laid above the FDS cement-based penetrating crystalline waterproof coating. At the same time, the gap between the floor tiles is 5 - 8 mm and filled with jointing agent, further enhancing the anti-slip performance of the ground, reducing the occurrence of slipping accidents, and ensuring the safety of users.

[0026] The design of the dry-mix mortar combined with the neat cement layer makes the laying process of the floor tiles more convenient, ensures the flatness and firmness of the floor tile laying, reduces the construction difficulty and time, improves the construction efficiency, and reduces the construction cost.

[0027] The combined use of FDS cementitious capillary crystalline waterproof coating, dry - hard mortar, and anti - slip floor tiles, combined with the drainage slope design, forms a multi - level waterproof and anti - slip system, comprehensively improving the waterproof, anti - slip, and drainage performance of the balcony, meeting the usage requirements under various climate conditions, and extending the service life of the balcony.

[0028] Due to the adoption of high - efficiency waterproof and anti - slip materials and processes, the overall structure is more durable, reducing the frequency and cost of later maintenance and repair, and providing users with a more economical and long - lasting usage experience.

[0029] Furthermore, there is a dry - hard mortar with a thickness of 20 mm and a ratio of 1:4 between the FDS cementitious capillary crystalline waterproof coating and the anti - slip floor tiles. A layer of plain cement is sprinkled on the surface of the dry - hard mortar. The anti - slip floor tiles are laid on the cast - in - place reinforced concrete slab and are above the FDS cementitious capillary crystalline waterproof coating. The gap between the anti - slip floor tiles is 5 - 8 mm, and the gap is filled with jointing agent. The cast - in - place reinforced concrete slab uses a cement mortar layer with a thickness of 20 mm and a ratio of 1:2.5 to form a building material drainage slope with a slope of 1%.

[0030] By setting a dry - hard mortar with a thickness of 20 mm and a ratio of 1:4 between the FDS cementitious capillary crystalline waterproof coating and the anti - slip floor tiles, and sprinkling a layer of plain cement on its surface, the adhesion between the waterproof layer and the anti - slip floor tiles is significantly enhanced, ensuring the stability of the floor tile laying, avoiding the loosening or falling off of the floor tiles during use, and improving the durability and reliability of the overall structure.

[0031] The cast - in - place reinforced concrete slab uses a cement mortar layer with a thickness of 20 mm and a ratio of 1:2.5 to form a drainage slope design of building materials with a slope of 1%, effectively promoting the rapid drainage of the water on the balcony surface, preventing waterlogging, reducing the leakage risk, protecting the long - term service life of the waterproof layer and floor tiles, and thus significantly improving the overall waterproof performance of the balcony.

[0032] The anti - slip floor tiles are laid above the FDS cementitious capillary crystalline waterproof coating, and at the same time, the gap between the floor tiles is 5 - 8 mm, filled with jointing agent, further enhancing the anti - slip performance of the ground, preventing slipping accidents, and improving the safety of users.

[0033] The design of using dry - hard mortar and plain cement layer simplifies the floor tile laying process, ensures the flatness and firmness of the floor tile laying, reduces the construction difficulty and time, improves the construction efficiency, and reduces the construction cost.

[0034] This design comprehensively uses FDS cementitious capillary crystalline waterproof coating, dry - hard mortar, anti - slip floor tiles and drainage slopes to form a multi - level waterproof, anti - slip and drainage system, comprehensively improving the waterproof, anti - slip and drainage performance of the balcony, meeting the usage requirements under various climate conditions, and extending the service life of the balcony.

[0035] Due to the adoption of high - efficiency waterproof and anti - slip materials and processes, the overall structure is more durable, reducing the frequency and cost of later maintenance and repair, and providing users with a more economical and long - lasting usage experience.

[0036] The optimized construction process reduces the complexity and procedures of on - site construction, shortens the construction period, improves construction efficiency, reduces labor and material costs, and has significant economic benefits.

[0037] Furthermore, a first extruded polystyrene board insulation layer is provided between the FDS cementitious capillary crystalline waterproof coating and the dry - hard mortar. At the bottom of the cast - in - place reinforced concrete slab, a second extruded polystyrene board insulation layer, a polymer anti - crack mortar with a thickness of 5 mm and mixed in a ratio of 1:2.5 and containing alkali - resistant fiberglass mesh, two layers of N - type putty, primer and two layers of paint are successively arranged from top to bottom.

[0038] The cast - in - place reinforced concrete slab uses a cement mortar layer with a thickness of 20 mm and a ratio of 1:2.5 to form a building material drainage slope with a slope of 1%.

[0039] By setting a first extruded polystyrene board insulation layer between the FDS cementitious capillary crystalline waterproof coating and the dry - hard mortar, and a second extruded polystyrene board insulation layer at the bottom of the cast - in - place reinforced concrete slab, the thermal insulation performance of the balcony is significantly improved, the thermal bridge effect is reduced, the energy efficiency is increased, especially suitable for cold regions in the north, and the living comfort is improved.

[0040] The combination of the extruded polystyrene board insulation layer with the waterproof coating and the dry - hard mortar effectively prevents the penetration and accumulation of moisture, further improving the waterproof effect of the balcony. At the same time, the dry - hard mortar layer increases the bonding strength of the floor tiles, preventing the floor tiles from loosening.

[0041] Setting a polymer anti - crack mortar with a thickness of 5 mm and mixed in a ratio of 1:2.5 and containing alkali - resistant fiberglass mesh at the bottom of the cast - in - place reinforced concrete slab significantly improves the crack - resistance performance of the structure, avoids crack problems caused by temperature changes and stress concentration, and extends the service life and maintenance cycle of the balcony.

[0042] The combination of two layers of N - type putty, primer and two layers of paint forms a multi - level protection system, which not only improves the aesthetics of the balcony, but also further enhances the waterproof, moisture - proof, mildew - proof and anti - aging performance, effectively protecting the underlying structural materials and extending the overall service life of the balcony.

[0043] Standardized materials and processes are adopted, the construction process is optimized, and the construction efficiency is improved. In particular, the use of extruded polystyrene board insulation layer and polymer anti-cracking mortar makes the construction simpler and faster, reduces the construction time and labor costs, and at the same time ensures the construction quality.

[0044] Through multi-level waterproof, anti-slip, insulation and anti-cracking designs, the overall performance of the balcony has been comprehensively improved, adapting to various complex climate conditions and usage environments, and significantly enhancing the safety, comfort and durability of the balcony.

[0045] Due to the optimized combination of materials and processes, the maintenance frequency and repair costs during the use of the balcony are reduced, providing users with a more economical and long-lasting usage experience, and enhancing user satisfaction and living quality.

[0046] On the cast-in-place reinforced concrete slab, a 20-mm-thick cement mortar layer with a ratio of 1:2.5 is used to form a building material drainage slope design with a slope of 1%, effectively promoting the rapid drainage of the surface water on the balcony, preventing water accumulation, reducing the risk of leakage, protecting the long-term service life of the waterproof layer and floor tiles, and thus significantly enhancing the overall waterproof performance of the balcony.

[0047] Further, a first extruded polystyrene board insulation layer is provided between the FDS cement-based penetrating crystalline waterproof coating and the dry-hardened cement mortar. The bottom of the cast-in-place reinforced concrete slab is successively provided with a second extruded polystyrene board insulation layer, a polymer anti-cracking mortar with a thickness of 5 mm and a ratio of 1:2.5 and containing alkali-resistant fiberglass mesh, two layers of N-type putty, a primer and two layers of paint.

[0048] The cast-in-place reinforced concrete slab is provided with a structural slab slope ， The slope of the drainage slope is 1%.

[0050] Under the combined action of the waterproof layer and the insulation layer, the waterproof performance of the balcony is significantly improved. The use of the FDS cement-based penetrating crystalline waterproof coating gives the balcony a lasting waterproof effect, avoids water penetration and water accumulation, protects the lower structure from moisture damage, and extends the service life.

[0051] A polymer anti-cracking mortar with a thickness of 5 mm and mixed in a ratio of 1:2.5 and containing alkali-resistant fiberglass mesh is set at the bottom of the cast-in-place reinforced concrete slab, effectively enhancing the anti-cracking performance of the structure, preventing cracks caused by temperature changes or stress concentration, and ensuring the stability and durability of the structure.

[0052] Two layers of N-type putty, primer, and two layers of topcoat are sequentially set at the bottom of the balcony, forming a multi-layer protection system, which not only improves the aesthetics of the balcony but also enhances its waterproof, moisture-proof, mildew-proof, and anti-aging properties, comprehensively protecting the structural materials and extending the service life.

[0053] The use of standardized materials and processes simplifies the construction process and improves construction efficiency. In particular, the use of extruded polystyrene board insulation layer and polymer anti-cracking mortar makes the construction process faster, reduces construction time and costs, and improves construction quality.

[0054] Through multi-level waterproof, insulation, anti-cracking, and decoration designs, the comprehensive performance of the balcony has been comprehensively improved, adapting to various complex climate conditions and usage environments, and ensuring the safety, comfort, and durability of the balcony during use.
