Description

Technical Field

[0001] The present application relates to the technical field of building waterproofing, and in particular to a waterproofing system. Background Art

[0002] Waterproofing projects play an important role in building construction. Their main purpose is to prevent water from eroding buildings, extend the service life of buildings, and ensure the safety and comfort of the internal environment of buildings. With the rapid development of the construction industry, people have higher and higher requirements for the waterproof performance of buildings, especially in complex environments, such as basements, roofs, and special structural parts.

[0003] Water seepage and leakage in waterproof layers have always been a common quality problem that is difficult to solve in the construction industry. Whether it is waterproof coatings such as polyurethane series, acrylic series, waterproof mortar, etc., or waterproof rolls such as asphalt waterproof rolls, modified asphalt rolls, synthetic polymer rolls, etc., water seepage and leakage occur frequently. Once a leakage occurs, it will affect the service life and construction quality of the entire building structure, and subsequent repairs are very difficult, seriously affecting the overall construction cost. Contents of the invention In order to reduce the probability of water seepage and leakage, and improve the service life and construction quality of the entire building structure, the present application provides a waterproof system.

[0004] The present application provides a waterproof system, which adopts the following technical solution: it includes two layers of SBS waterproof membranes and non-curing asphalt waterproof coating, wherein the SBS waterproof membranes are used to be attached to a base layer and the two layers of the SBS waterproof membranes are laid alternately up and down, and the non-curing asphalt waterproof coating is used to be applied to the junction of the SBS waterproof membranes.

[0005] By adopting the above technical scheme, a composite waterproof structure combining roll waterproofing with coating waterproofing is adopted, and the characteristics of the two materials are fully utilized, the waterproofing quality is significantly enhanced, the probability of water seepage and leakage is reduced, and the service life and construction quality of the entire building structure are improved.

[0006] Preferably, it also includes a polymer self-adhesive film waterproofing coiled material, and the polymer self-adhesive film waterproofing coiled material is attached to the non-curing asphalt waterproofing coating.

[0007] By adopting the above technical solution, the paste-like properties of the non-curing asphalt coating can fully fill the cracks and holes in the base layer, forming a continuous and seamless sealing layer, eliminating the risk of water leakage, while the polymer self-adhesive film roll provides a high-strength puncture-resistant and tear-resistant protective layer to resist external force damage such as backfill soil and mechanical construction. The non-curing asphalt coating and the polymer self-adhesive film waterproof roll form a double barrier to improve the anti-seepage ability.

[0008] Preferably, the seams of the two layers of the SBS waterproof membrane are staggered by 1 / 3-1 / 2 of the width.

[0009] If the joints of the upper and lower layers of SBS waterproof membrane are completely aligned, moisture may directly penetrate into the base layer along the weak points of the joints. By adopting the above technical solution, the joints of the two layers of SBS waterproof membrane are staggered by 1 / 3-1 / 2 of the width, and the joints of the upper layer of SBS waterproof membrane cover the joints of the lower layer of SBS waterproof membrane to form a staggered seal. Water seepage needs to take a longer detour, significantly reducing the probability of leakage.

[0010] Preferably, it is constructed by the following steps: S1. Construction preparation; S2. Base treatment: Clean the base for attaching the SBS waterproof membrane, remove the debris, dust and ash from the base, and ensure that the base is clean and flat; S3. Applying the base treatment agent: After cleaning, fully stir the base treatment agent and roll the base treatment agent on the base; S4, waterproofing membrane paving: paving two layers of SBS waterproofing membrane; S5, applying waterproof coating: applying the non-curing asphalt waterproof coating by brushing; S6. Inspection and acceptance.

[0011] By adopting the above technical solution and utilizing the performance of non-curing asphalt waterproof coating and SBS membrane materials, the waterproof materials of the two sections can be effectively connected. The construction is simple and convenient, which can effectively improve the waterproof and anti-seepage capabilities and ensure the construction quality of the building waterproof system.

[0012] Preferably, between the step S3 and the step S4, an additional layer of the SBS waterproof membrane needs to be laid, and the bottom surface of the cut SBS waterproof membrane is baked to a molten state using a flame heater, and immediately pasted on the base layer coated with a base treatment agent.

[0013] By adopting the above technical solution, the additional layer preferentially covers the weak areas prone to leakage, reducing the damage caused by stress concentration; the additional layer can disperse external force, reduce the probability of the two layers of SBS waterproof membrane being punctured or torn, and improve the tear resistance; the additional layer and the two layers of SBS waterproof membrane are made of the same material and have consistent physical and chemical properties, and can be completely fused during hot-melt welding or gluing, avoiding delamination and hollowing due to material differences. The temperature deformation coefficients of the same materials are consistent, reducing the risk of cracking due to temperature difference deformation, and the additional layer and the two layers of SBS waterproof membrane age synchronously, avoiding the formation of leakage points due to local material aging differences.

[0014] Preferably, during the paving process of the SBS waterproof membrane in step S4, a gasoline blowtorch is used to bake the bottom of the SBS waterproof membrane and the surface of the base layer to melt the asphalt at the bottom of the SBS waterproof membrane, and the membrane is rolled forward while being baked, and a pressure roller is used during the paving process.

[0015] By adopting the above technical solution, the bottom of the SBS waterproof membrane is usually covered with a modified asphalt self-adhesive layer or a hot melt adhesive layer. The asphalt is softened to a molten state by baking with a blowtorch to form a uniform bonding layer that is tightly bonded to the base layer. The molten asphalt can penetrate the tiny pores on the surface of the base layer, greatly improving the bonding strength between the membrane and the base layer. The hot melt asphalt solidifies rapidly after cooling, shortening the construction interval time and speeding up the project progress. Baking the base layer can evaporate residual moisture to prevent the moisture from vaporizing due to heat and causing the membrane to bulge. During baking, the air between the SBS waterproof membrane and the base layer is discharged through the pressure roller to form a bubble-free full adhesion effect, reducing the risk of leakage.

[0016] Preferably, the width of the non-curing asphalt waterproof coating in the step S5 applied at the waterproof junction of the post-cast strip is not less than 200 mm.

[0017] By adopting the above technical solution, when overlapping with the adjacent waterproof layer, a width greater than 200 mm provides sufficient overlapping area. Even if there are defects in the local overlap, the overall sealing can be ensured by the wide margin.

[0018] Preferably, the thickness of the non-curing asphalt waterproof coating in step S5 is detected by needle testing.

[0019] Uncured asphalt is always in a paste or semi-solid state. Traditional testing instruments may cause sound wave attenuation or signal interference due to the viscoelasticity of the material. By adopting the above technical solution, the needle test method directly measures through physical puncture. The coating thickness can be read directly after puncture without waiting for data processing. It can be immediately determined whether it meets the standard. If the thickness does not meet the standard or local reinforcement is required, some paint can be removed with a hanging board to fill it up. The result is more reliable and improves construction efficiency.

[0020] Preferably, after the non-curing asphalt waterproof coating in step S5 is applied, the polymer self-adhesive film waterproofing membrane is immediately pasted at the connection with the adjacent section. When laying the polymer self-adhesive film waterproofing membrane, press the polymer self-adhesive film waterproofing membrane from one end, evenly lay it forward and scrape it flat.

[0021] By adopting the above technical scheme, the non-curing asphalt coating and the polymer self-adhesive film waterproofing membrane form a double barrier to improve the anti-seepage ability; and when laying the polymer self-adhesive film waterproofing membrane, press the polymer self-adhesive film waterproofing membrane from one end, lay it forward evenly and scrape it flat, expel the internal air, and ensure full and dense bonding.

[0022] Preferably, the uncured asphalt waterproof coating in the step S5 is additionally applied with 50 mm at the front end of the SBS waterproof coiled material in each of the two sections.

[0023] By adopting the above technical solutions, In summary, the present application includes at least one of the following beneficial technical effects: 1. Adopting a composite waterproof structure combining coiled material waterproofing and coating waterproofing, making full use of the characteristics of the two materials, significantly enhancing the waterproof quality, reducing the probability of water seepage and leakage, and improving the service life and construction quality of the entire building structure; 2. The joints of the upper SBS waterproof coiled material cover the joints of the lower SBS waterproof coiled material, forming a staggered seal, and the seeping water needs to bypass a longer path, significantly reducing the leakage probability; 3. The uncured asphalt coating and the polymer self-adhesive film waterproof coiled material form a double barrier, improving the anti-seepage ability. Description of the Drawings

[0026] The following further describes the present application in detail with reference to the drawings.

[0027] In order to reduce the probability of water seepage and leakage, and improve the service life and construction quality of the entire building structure, the present application discloses a waterproof system.

[0028] Refer to Figure 1 and Figure 2A waterproof system includes two layers of SBS waterproof membranes 10 and a non-curing asphalt waterproof coating 11, wherein the two layers of SBS waterproof membranes 10 are laid alternately up and down, and the non-curing asphalt waterproof coating 11 is applied to the intersection of the SBS waterproof membranes 10, thereby forming a multi-layer composite waterproof structure, which effectively solves the problems of loose overlap of the waterproof layer and leakage at the joints. The composite waterproof structure of membrane waterproofing combined with coating waterproofing is adopted, and the characteristics of the two materials are fully utilized. The waterproof quality is significantly enhanced, the probability of seepage and leakage is reduced, and the service life and construction quality of the entire building structure are improved.

[0029] In this embodiment, in order to further improve the waterproof performance, the two layers of SBS waterproof membrane 10 can use SBS waterproof membrane 10 of different thicknesses. For example, the thickness of the upper layer of SBS waterproof membrane 10 is 3 mm, and the thickness of the lower layer of SBS waterproof membrane 10 is 4 mm, forming a double-layer structure with different thicknesses. In addition, the overlap of the long and short sides of the two layers of SBS waterproof membrane 10 should be ≥ 100 mm. This design can not only increase the overall thickness of the waterproof system, but also compensate for the unevenness of the base layer 12 to a certain extent. The local weak points of the upper and lower layers of SBS waterproof membrane 10 are staggered by 1 / 3-1 / 2 of the width. If the seams of the upper and lower layers of SBS waterproof membrane 10 are completely aligned, moisture may directly penetrate into the base layer 12 along the weak points at the overlap of the seams. The seams of the two layers of SBS waterproof membrane 10 are staggered by 1 / 3-1 / 2 of the width, and the seams of the upper layer of SBS waterproof membrane 10 cover the seams of the lower layer of SBS waterproof membrane 10 to form a staggered seal. The seepage water needs to take a longer detour, which significantly reduces the probability of leakage.

[0030] In addition, it also includes a polymer self-adhesive film waterproofing coiled material 14 , which is attached to the non-curing asphalt waterproofing coating 11 .

[0031] Specifically, refer to Figure 1-Figure 3 This waterproof system is constructed through the following steps: S1. Construction preparation; S2. Base layer 12 treatment: clean the base layer 12 for attaching the SBS waterproof membrane 10, clean the base layer 12 from debris, dust, and ash, and ensure that the base layer 12 is clean and flat; S3, brushing the base treatment agent 13: After cleaning, fully stir the base treatment agent 13 and roll the base treatment agent 13 on the base 12; S4, waterproofing membrane paving: perform paving construction of two layers of SBS waterproofing membrane 10; S5, applying waterproof coating: applying the non-curing asphalt waterproof coating 11 by brushing; S6. Inspection and acceptance.

[0032] First of all, during construction preparation, it is necessary to organize expert appraisal and demonstration for the construction measures of the waterproofing system at the connection parts. Only after the appraisal is qualified can it be used for actual construction on site; it is also necessary to organize project management personnel to prepare a special construction plan for waterproofing of underground post-casting joints according to design requirements and on-site conditions, and then explain the plan, technical operations and safety operations to each construction team, and issue a construction task order to make each construction team clear about the relevant tasks, quality, safety, progress and other requirements. Finally, organize various departments of the project management department to test the material performance involved in the construction of underground waterproofing projects according to the design drawings and material and atlas specifications to ensure the quality of the materials.

[0033] Secondly, when processing the base layer 12, use a broom and a shovel to clean the base layer 12, clean up the debris, dust, and slag on the base layer 12, and ensure that the base layer 12 is clean and flat. Then, make the inner and outer corners of the base layer 12 into arcs, make a 50mm small arc at the inner corner, and make a 10mm small arc at the outer corner to facilitate the pasting of the SBS waterproof membrane 10; after the base layer 12 is cleaned, inspect and accept the base layer 12 to ensure that the surface of the base layer 12 is solid and there is no visible water, and conduct a moisture content test. The moisture content of the base layer 12 should be ≤9%. Only after the base layer 12 is accepted and qualified can subsequent construction be carried out.

[0034] After cleaning, apply the base treatment agent 13. Stir the base treatment agent 13 fully before applying. The thickness should be even when rolling, and no leakage or bottom exposure should be allowed. Follow the principle of high first and low later. After the base treatment agent 13 is applied, it should be dry enough to not stick to your hands before additional roll material paving can be carried out.

[0035] Between step S3 and step S4, an additional layer of SBS waterproof membrane 10 is required to be laid. The bottom surface of the cut SBS waterproof membrane 10 is baked to a molten state using a flame heater, and then immediately pasted on the base layer 12 coated with a base treatment agent 13. The additional layer preferentially covers weak areas that are prone to leakage to reduce damage caused by stress concentration; the additional layer can disperse external forces, reduce the probability of the two layers of SBS waterproof membrane 10 being punctured or torn, and improve tear resistance; the additional layer and the two layers of SBS waterproof membrane 10 are made of the same material and have consistent physical and chemical properties. They can be completely fused during hot-melt welding or gluing to avoid delamination and hollowing due to material differences. The temperature deformation coefficients of the same materials are consistent to reduce the risk of cracking due to temperature difference deformation, and the additional layer and the two layers of SBS waterproof membrane 10 are aged synchronously to avoid the formation of leakage points due to local material aging differences.

[0036] After the additional layer is paved, the SBS waterproof membrane 10 paving reference line is marked on the surface of the base layer 12 according to the width of the SBS waterproof membrane 10 and the size of the lap joint, and then the SBS waterproof membrane 10 paving construction is carried out according to the reference line. The bottom 4mm thick SBS waterproof membrane 10 is paved first. In the paving process of the SBS waterproof membrane 10 in step S4, a gasoline blowtorch is used to bake the bottom of the SBS waterproof membrane 10 and the surface of the base layer 12 to melt the asphalt at the bottom of the SBS waterproof membrane 10, and the SBS waterproof membrane 10 is rolled forward while baking. The paving process uses a roller to roll the SBS waterproof membrane 10. The bottom of the SBS waterproof membrane 10 is rolled through the bottom of the SBS waterproof membrane 10. It is often covered with a modified asphalt self-adhesive layer or a hot melt adhesive layer. The asphalt is softened to a molten state by baking with a blowtorch to form a uniform bonding layer, which is tightly bonded to the base layer 12. The molten asphalt can penetrate the tiny pores on the surface of the base layer 12, greatly improving the bonding strength between the roll material and the base layer 12. The hot melt asphalt solidifies rapidly after cooling, shortening the construction interval time and speeding up the project progress. Baking the base layer 12 can evaporate residual moisture to prevent the moisture from vaporizing due to heat and causing the roll material to bulge. During baking, the air between the SBS waterproof roll material 10 and the base layer 12 is discharged through the pressure roller, forming a bubble-free full adhesion effect and reducing the risk of leakage.

[0037] After the first layer of membrane construction is inspected and qualified, the second layer of 3mm thick SBS waterproof membrane 10 is laid. The laying process is the same as the first layer. The upper and lower layers of SBS waterproof membrane 10 must not be laid perpendicular to each other, but should be laid parallel to the first layer of SBS waterproof membrane 10, and the joints of the upper and lower layers of SBS waterproof membrane 10 should be staggered by 1 / 3-1 / 2 of the width.

[0038] The non-curing asphalt waterproof coating 11 is applied by brushing. During the brushing process, it can be applied one by one according to the width of the roll material, or it can be applied in multiple layers at the same time. Among them, the width of the non-curing asphalt waterproof coating 11 applied at the waterproof junction of the post-cast strip in step S5 is not less than 200mm. The width greater than 200mm provides sufficient overlapping area. Even if there are defects in the local overlap, the overall sealing can be ensured by the wide margin. After brushing at the waterproof junction of the post-cast strip with a width of not less than 200mm, the thickness of the non-curing asphalt waterproof coating 11 in step S5 is detected by the needle measurement method. The non-curing asphalt is always in a paste or semi-solid state. Traditional detection instruments may cause sound wave attenuation or signal interference due to the viscoelasticity of the material. The needle measurement method directly measures through physical puncture. The coating thickness is directly read after puncture. There is no need to wait for data processing, and it can be immediately determined whether it meets the standard. If the thickness does not meet the standard or local reinforcement is required, some paint is removed with a hanging board to fill it up. The result is more reliable and the construction efficiency is improved.

[0039] Furthermore, after the non-curing asphalt waterproof coating 11 in step S5 is applied, the polymer self-adhesive film waterproofing membrane 14 is immediately pasted at the connection with the adjacent section. When laying the polymer self-adhesive film waterproofing membrane 14, the polymer self-adhesive film waterproofing membrane 14 is pressed from one end, evenly laid forward and scraped flat, and the internal air is discharged to ensure full and dense bonding; and the non-curing asphalt waterproof coating 11 in step S5 is additionally applied 50mm at the front end of the SBS waterproofing membrane 10 of the two sections.

[0040] After the waterproof system is completed, each part is inspected, with a focus on the sealing of the overlapping edges of the SBS waterproof membrane 10, whether the overlapping length of the SBS waterproof membrane 10 meets the requirements, whether the outer edge of the SBS waterproof membrane 10 is sealed with asphalt, etc., and whether the waterproof system is damaged. Only after passing the inspection can the waterproof protective layer be constructed. The thickness of the waterproof protective layer is 50mm, and maintenance is carried out in time after the construction is completed to ensure that the overall waterproof system is well sealed.

[0041] The implementation principle of a waterproof system in an embodiment of the present application is: by utilizing the performance of non-curing asphalt waterproof coating 11 and SBS roll material, the waterproof materials of two sections can be effectively connected, the construction is simple and convenient, and the waterproof and anti-seepage capabilities can be effectively improved, the construction quality of the building waterproof system can be guaranteed, the probability of seepage and leakage can be reduced, the service life and construction quality of the entire building structure can be improved, and the service life and construction quality of the entire building structure can be improved.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
