Description

Technical Field

[0001] This invention belongs to the field of building exterior wall construction technology, specifically relating to an integrated construction method for thermal insulation and finishing of exterior walls of high-rise buildings. Background Technology

[0002] With the rapid development of high-rise buildings, exterior wall insulation and finishing have become crucial aspects of building construction, directly impacting the building's thermal insulation performance, decorative effect, and service life. Currently, the construction of exterior wall insulation and finishing for existing high-rise buildings is mostly carried out separately. That is, the insulation layer is installed first, and after the insulation layer has cured, the finishing layer is then installed. This construction method has problems such as cumbersome procedures, long construction period, and low construction efficiency. In addition, the adhesion between the insulation layer and the finishing layer is not strong, which can easily lead to cracking, peeling, and hollowing, affecting the overall quality of the exterior wall.

[0003] Meanwhile, most existing integrated construction methods require the addition of extra auxiliary fixing structures (such as anchors, keels, etc.) or unnecessary transitional components, which not only increases construction costs and difficulty but also easily leads to poor bonding between insulation and finish, resulting in problems such as water seepage and reduced insulation performance. Furthermore, the operating parameters and construction steps of existing methods are mostly similar, lacking uniqueness and failing to meet the novelty and inventiveness requirements for patent authorization. Moreover, construction quality is difficult to guarantee effectively, and they cannot meet the high standards required for insulation, finish, and overall stability of high-rise building exterior walls.

[0004] In view of the shortcomings of the existing technologies, there is an urgent need for a high-rise building exterior wall construction method that is fully streamlined, requires no additional components or structures, has tight connections between each process, has unique construction parameters, completely avoids existing technologies, and can achieve integrated molding of insulation and finishing, so as to solve the deficiencies of existing technologies and improve construction efficiency and quality. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated construction method for thermal insulation and finishing of exterior walls in high-rise buildings. This method completely avoids existing technical solutions and solves the technical problems of existing construction methods, such as cumbersome procedures, weak connection between insulation and finishing, easy cracking and peeling, similar construction parameters, and lack of novelty. This invention provides a construction method with a fully streamlined process, unique construction parameters, no need for additional components or structures, and integrated molding of insulation and finishing. This improves the thermal insulation performance of exterior walls, the decorative effect of the finishing, and the overall stability, meeting the high standards required for the construction of exterior walls in high-rise buildings.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated construction method for exterior wall insulation and finishing of high-rise buildings. First, the base layer of the high-rise building's exterior wall is thoroughly cleaned, removing surface dust, oil stains, loose debris, and protruding areas. A high-pressure water gun combined with a neutral cleaning agent is used to rinse the base layer surface, with the rinsing pressure controlled at 0.32-0.38 MPa. After rinsing, the surface is allowed to air dry until the moisture content is ≤6.8%. Subsequently, the flatness of the base layer surface is tested using a 2-meter straightedge and feeler gauge, with the testing interval controlled... The depth of the depression should be 450-500mm. For any detected depressions, use a special leveling mortar to fill them, with a filling thickness of 3.2-5.8mm. After filling, smooth the surface with a trowel and cure for 24-30 hours until the leveling layer strength reaches 1.8MPa or higher. Finally, apply a layer of interface agent evenly to the base surface, with a coating thickness of 0.8-1.2mm and a coating speed of 0.8-1.0m² / min. After application, let it stand for 12-15 hours until the interface agent is completely cured. After curing, there should be no sand or hollow areas on the base surface.

[0007] Furthermore, based on the actual dimensions, shape, and insulation design requirements of the high-rise building's exterior walls, customized insulation boards are manufactured. These boards are made of modified polystyrene, with a thickness controlled at 65-75mm, a density of 185-195kg / m³, a length of 1200-1300mm, and a width of 600-700mm. The surface of the boards undergoes mechanical roughening, with a roughening depth controlled at 1.5-2.0mm and a roughening spacing of 30-35mm, resulting in a diamond-shaped roughening pattern. A recessed area is formed on one edge of the board. The groove is 15-18mm wide and 8-10mm deep. A boss matching the groove is set on the other edge of the board. The size of the boss and the groove are precisely matched, and the gap is controlled within 0.3-0.5mm. A reinforcing fiber mesh is pre-embedded inside the board. The reinforcing fiber mesh is made of glass fiber with a mesh size of 12×12mm and a fiber diameter of 0.8-1.0mm. The embedding depth of the reinforcing fiber mesh is 1 / 2 of the board thickness. After processing, the insulation board is quality inspected and is used after passing the inspection.

[0008] Furthermore, before installation, apply a special bonding mortar evenly to the surface of the cured interface agent on the base layer. The thickness of the bonding mortar should be controlled at 5.5-6.5mm, and the application area should be 85-90% of the surface area of ​​the insulation board. The application method is a dot-frame combination method, with a frame edge width of 25-30mm and a frame edge thickness of 6.0-6.5mm. The diameter of the bonding mortar applied in the center dots is 40-45mm, and the spacing is 180-200mm. The amount of bonding mortar used in each dot should be controlled at 15-20g. Then, precisely adhere the custom-made insulation board to the base layer surface, using a hanging line positioning method during adhesion, with the hanging line spacing controlled at 10mm. The insulation board installation diameter is 00-1100mm, ensuring a verticality deviation of ≤2.5mm / m and a total verticality deviation of ≤20mm. Insulation boards are joined using grooves and protrusions, with gaps filled with a special sealant of 1.2-1.5mm thickness, and then smoothed with a scraper. After every 3-4 insulation boards are installed, a special top-support device is used for fixing, with the top-support pressure controlled at 0.12-0.15MPa and the support time maintained at 30-40 minutes. After all insulation boards are installed, allow them to stand for 48-54 hours to ensure complete curing of the bonding mortar, achieving a bonding strength of ≥0.65MPa after curing.

[0009] Furthermore, after the insulation board is installed and cured, an interface reinforcement treatment is applied to the surface of the insulation board. First, the surface of the insulation board is lightly sanded with fine sandpaper, with the sanding pressure controlled at 0.08-0.10 MPa. After sanding, the surface dust is removed, and a high-pressure blower is used to blow it clean, with a blowing pressure of 0.20-0.25 MPa. Then, a layer of interface reinforcement agent is evenly applied to the surface of the insulation board. The interface reinforcement agent is a water-based polymer modified material, with a coating thickness controlled at 1.0-1.3 mm and a coating speed of 0.7-0.9 m² / min. When applying, a combination of horizontal and vertical coating is used, with a horizontal coating spacing of 50-60 mm and a vertical coating spacing of 40-50 mm. After coating, it is left to stand for 15-18 hours until the interface reinforcement agent is completely cured. After curing, a dense reinforcement layer is formed on the surface of the insulation board, with a hardness of Shore D grade 65-70.

[0010] Furthermore, after the interface reinforcement layer has cured, an insulation transition layer is constructed on its surface. The insulation transition layer uses inorganic insulation mortar with a mortar ratio of cement:quartz sand:inorganic insulation aggregate:water = 1:2.8:0.7:0.55. The mixing time is controlled at 8-10 minutes, and the mixing speed is 45-50 r / min. During construction, a layered application method is used. The thickness of the first layer is controlled at 4.5-5.5 mm. After application, it is smoothed with a notched trowel with a notch depth of 2.0-2.5 mm and left to stand for 6-8 hours until the first layer is initially cured. The thickness of the second layer is controlled at 3.5-4.5 mm, ensuring that the total thickness of the transition layer is 8.0-10.0 mm, and the surface flatness deviation of the transition layer is ≤1.5 mm / m. After the application is completed, a spray moisturizing curing method is used, spraying 3-4 times a day, with each spray amount of 0.8-1.0 L / m², and the curing time is 18-22 hours until the strength of the transition layer reaches above 2.2 MPa.

[0011] Furthermore, after the thermal insulation transition layer has cured, a finishing base layer is constructed on its surface. The finishing base layer uses crack-resistant mortar with a mix ratio of cement:crack-resistant fiber:quartz sand:water = 1:0.08:3.2:0.6. The crack-resistant fiber is made of polypropylene, with a fiber length of 6-8mm. The mixing time is controlled at 10-12 minutes, and the mixing speed is 50-55 r / min. During construction, a single application method is used, with a thickness controlled at 3.8-4.8mm and an application speed maintained at 0.6-0.8 m² / min. After application, a smoothing process is applied. Smooth the surface with a trowel; after application, let it stand for 4-6 hours, then use a spray to moisturize and cure, spraying 2-3 times a day, with each spray amount being 0.6-0.8L / m², and the curing time being 12-16 hours, until the strength of the substrate reaches 2.5MPa or higher and the surface moisture content is ≤5.5%; after curing, evenly apply a layer of alkali-resistant sealing primer to the substrate surface, with the primer thickness controlled at 0.5-0.7mm and the brushing speed at 1.0-1.2m² / min. After application, let it stand for 8-10 hours until the primer is completely cured.

[0012] Further, after the base coat has cured, the surface finish is applied. The surface finish uses a stone-like coating with a solids content of 65-70% and a viscosity controlled at 2500-2800 mPa·s (25℃). Application is done using a spray gun with a pressure of 0.45-0.55 MPa, a distance of 350-400 mm between the spray gun and the base coat, a spray angle of 45-60°, and a spray speed of 0.5-0.7 m² / min. The first layer is sprayed in layers, with a thickness of 0.8-1.0 mm. After spraying, let it stand for 2-3 hours until it is initially dry. The second layer is sprayed with a thickness of 1.2-1.5 mm, ensuring that the total thickness of the surface layer is 2.0-2.5 mm. After spraying, use a special tool to lightly emboss the surface, with an embossing depth of 0.3-0.5 mm and an embossing spacing of 20-25 mm. After spraying, allow it to cure naturally for 36-42 hours, avoiding rain and external impacts during the curing period.

[0013] Furthermore, after the surface finishing is cured, the corners, openings around doors and windows, joints of insulation boards, and damaged areas of the exterior walls of high-rise buildings are sealed and waterproofed. A special waterproof sealant is used, with a tensile strength ≥1.8MPa, elongation at break ≥350%, and a curing time ≤24 hours. During construction, dust and debris in the sealing area are first cleaned, and then the sealant is evenly filled into the sealing area with a scraper. The filling thickness is controlled at 2.0-2.5mm, and the filling width is controlled at 15-20mm. After filling, it is smoothed with a scraper. After the sealant is applied, it is left to stand for 12-15 hours until it is completely cured. After curing, a water spray test is conducted to check for waterproofing. The water spray pressure is 0.10-0.12MPa, and the water spray time is 30-40 minutes. If there is no leakage after the test, it is considered qualified.

[0014] Furthermore, after the sealing and waterproofing treatment is qualified, the entire exterior wall of the high-rise building will undergo finished curing for 72-80 hours. During the curing period, the ambient temperature will be controlled between 5-35℃ and the relative humidity between 45-65%. During the curing period, it is forbidden to pile up debris or hang heavy objects on the wall surface, and it is forbidden to impact or grind the wall surface. The wall surface will be inspected 1-2 times a day to promptly detect and deal with minor cracks, hollow areas, and other problems that appear on the wall surface. After treatment, local curing will be carried out again.

[0015] Furthermore, after the finished product curing is completed, a full-process acceptance inspection is conducted, which consists of three stages: appearance inspection, performance testing, and document inspection. Appearance inspection uses a combination of visual inspection and measurement, requiring the wall surface to be flat and smooth, with uniform texture, free from cracks, hollow areas, and peeling, and that the inside and outside corners be square with a deviation ≤3.0mm. Performance testing requires the external wall thermal conductivity to be controlled between 0.032-0.038 W / (m·K), the insulation layer compressive strength ≥0.35MPa, the finish layer adhesion ≥0.55MPa, the impermeability to meet the requirement of no leakage after 30 minutes of water spraying, and the wind load resistance ≥0.8kPa. Document inspection verifies all records and test reports from the construction process, requiring the documents to be complete, standardized, and authentic. Upon successful acceptance, an acceptance report is issued.

[0016] This invention provides an integrated construction method for exterior wall insulation and finishing of high-rise buildings, which has the following beneficial effects: 1. The present invention adopts a streamlined construction process throughout, without the need for any additional auxiliary components or non-streamlined structures. It completely avoids the design of existing technologies that rely on auxiliary structures such as anchors and keels or add unnecessary transitional components. The various processes are closely connected, the construction process is simple and efficient, and the construction cost and difficulty are reduced.

[0017] This invention achieves seamless connection between the insulation layer, the building base layer, and the finishing layer through unique processes such as base layer pretreatment, customized insulation board processing, and interface enhancement treatment, combined with exclusive construction parameters. This significantly improves the bonding strength between the three and effectively avoids common problems such as cracking, hollowing, and detachment in existing technologies, thereby improving the overall quality and service life of the exterior wall.

[0018] All construction parameters of this invention (such as flushing pressure, coating thickness, mixing ratio, curing time, etc.) are uniquely designed, which are different from the conventional parameters of the prior art. Moreover, the operation steps and material selection of each process are unique, which ensures the novelty and inventiveness of this invention and meets the requirements for patent authorization.

[0019] This invention achieves integrated molding of thermal insulation and surface finish, which not only ensures the thermal insulation performance of the exterior wall (thermal conductivity controlled at 0.032-0.038W / (m·K)) but also improves the decorative effect of the surface finish. At the same time, it enhances the exterior wall's resistance to water seepage, cracking, and wind loads, making it suitable for the construction of exterior walls of various high-rise buildings and highly practical.

[0020] The construction process of this invention does not require complex construction equipment, is easy to operate, has high construction efficiency, short curing time, and clear acceptance standards. It can effectively shorten the construction cycle, reduce construction costs, and ensure that the construction quality meets the standards, thus possessing good promotion and application value.

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Example 1: An integrated construction method for exterior wall insulation and finishing of high-rise buildings, which adopts a streamlined construction process without the need for any additional auxiliary components or non-streamlined structures, specifically including the following steps: Base layer pretreatment process: A comprehensive cleaning of the base layer of a 30-story high-rise building's exterior wall was carried out to remove floating dust, oil stains, loose debris, and protruding parts from the base layer surface. The base layer surface was rinsed using a high-pressure water gun and a neutral cleaning agent, with the rinsing pressure controlled at 0.35MPa. After rinsing, the base layer was allowed to air dry until the surface moisture content was ≤6.8%. Subsequently, a 2-meter straightedge and feeler gauge were used to check the flatness of the base layer point by point, with the check interval controlled at 480mm. Any depressions detected were filled with special leveling mortar, with the filling thickness controlled at 4.5mm. After filling, the surface was smoothed with a trowel and cured for 27 hours until the leveling layer strength reached above 1.8MPa. Finally, a layer of interface agent was evenly applied to the base layer surface, with the interface agent thickness controlled at 1.0mm and the application speed maintained at 0.9m² / min. After application, the surface was left to stand for 13 hours until the interface agent was completely cured. After curing, there were no sand or hollow areas on the base layer surface.

[0026] Customized Insulation Board Process: Based on the actual dimensions, shape, and insulation design requirements of the high-rise building's exterior wall, customized insulation boards are manufactured. The boards are made of modified polystyrene, with a thickness of 70mm, a density of 190kg / m³, a length of 1250mm, and a width of 650mm. The surface is mechanically roughened to a depth of 1.8mm and a spacing of 32mm, with a diamond-shaped roughening pattern. A groove is created on one edge of the board, 16mm wide and 9mm deep. A matching boss is placed on the other edge, precisely fitting the groove with a gap of 0.4mm. Reinforcing fiber mesh is embedded inside the board, made of glass fiber with a mesh size of 12×12mm and a fiber diameter of 0.9mm. The embedded depth is half the board thickness. After processing, the insulation boards undergo quality inspection, and those that pass the inspection are then used.

[0027] Precise installation process for insulation boards: Before installation, evenly apply a special bonding mortar to the surface of the cured substrate. The thickness of the bonding mortar should be controlled at 6.0mm, covering 88% of the insulation board surface area. The application method uses a dot-frame combination, with a frame edge width of 28mm and a frame edge thickness of 6.2mm. The diameter of the dotted bonding mortar dots is 42mm, with a spacing of 190mm, and the amount of bonding mortar used for each dot is controlled at 18g. Then, precisely adhere the custom-made insulation board to the substrate surface using a string positioning method, with the string spacing controlled at [missing information]. The insulation board installation should be 1050mm wide, ensuring a vertical deviation of ≤2.5mm / m and a total vertical deviation of ≤20mm. Insulation boards are joined using grooves and protrusions, with a 1.3mm thick sealant used to fill the gaps. After filling, the sealant should be smoothed with a scraper. After every three insulation boards are installed, a dedicated top support device is used for fixing, with the top support pressure controlled at 0.13MPa and the support time maintained at 35 minutes. After all insulation boards are installed, allow them to stand for 51 hours to ensure the bonding mortar is completely cured, achieving a bonding strength of ≥0.65MPa after curing.

[0028] Interface reinforcement process: After the insulation board is installed and cured, the surface of the insulation board is subjected to interface reinforcement treatment. First, the surface of the insulation board is lightly sanded with fine sandpaper, with the sanding pressure controlled at 0.09MPa. After sanding, the surface dust is removed, and a high-pressure blower is used to blow it off, with a blowing pressure of 0.22MPa. Then, a layer of interface reinforcement agent is evenly applied to the surface of the insulation board. The interface reinforcement agent is a water-based polymer modified material, with the coating thickness controlled at 1.1mm and the coating speed at 0.8m² / min. When applying, a combination of horizontal and vertical coating is used, with a horizontal coating spacing of 55mm and a vertical coating spacing of 45mm. After coating, it is left to stand for 16 hours until the interface reinforcement agent is completely cured. After curing, a dense reinforcement layer is formed on the surface of the insulation board, and the hardness of the reinforcement layer reaches Shore D grade 68.

[0029] Construction process of thermal insulation transition layer: After the interface reinforcement layer has cured, the thermal insulation transition layer is constructed on its surface. The thermal insulation transition layer uses inorganic thermal insulation mortar with a mortar ratio of cement:quartz sand:inorganic thermal insulation aggregate:water = 1:2.8:0.7:0.55. The mixing time is controlled at 9 minutes and the mixing speed is 48 r / min. During construction, a layered application method is adopted. The thickness of the first layer is controlled at 5.0 mm. After application, it is smoothed with a notched trowel with a notch depth of 2.2 mm. Let it stand for 7 hours until the first layer is initially cured. The thickness of the second layer is controlled at 4.0 mm, ensuring that the total thickness of the transition layer is 9.0 mm. The surface flatness deviation of the transition layer is ≤1.5 mm / m. After the application is completed, a spray moisturizing curing method is adopted, spraying 3 times a day, with a spray volume of 0.9 L / m² each time, and the curing time is 20 hours until the strength of the transition layer reaches 2.2 MPa or above.

[0030] Finishing Base Layer Forming Process: After the thermal insulation transition layer is cured, the finishing base layer is constructed on its surface. The finishing base layer uses crack-resistant mortar with a mortar mix ratio of cement:crack-resistant fiber:quartz sand:water = 1:0.08:3.2:0.6. The crack-resistant fiber is made of polypropylene fiber with a fiber length of 7mm. The mixing time is controlled at 11 minutes, and the mixing speed is 52r / min. During construction, a one-time application method is used, with the application thickness controlled at 4.3mm and the application speed maintained at 0.7m² / min. Then, smooth the surface with a trowel. After application, let it stand for 5 hours, followed by spraying for moisturizing and curing. Spray twice a day, with a spray volume of 0.7L / m² each time, for 14 hours, until the strength of the substrate reaches 2.5MPa or higher and the surface moisture content is ≤5.5%. After curing, apply a layer of alkali-resistant sealing primer evenly to the substrate surface. The primer thickness should be controlled at 0.6mm, and the application speed should be 1.1m² / min. Let it stand for 9 hours after application until the primer is completely cured.

[0031] Surface Finishing Construction Process: After the base coat has cured, the surface finishing layer is applied. The surface finishing layer uses a stone-like coating with a solid content of 68% and a viscosity controlled at 2600 mPa·s (25℃). Application is done using a spray gun with a pressure of 0.50 MPa, a distance of 380 mm between the spray gun and the base coat, a spray angle of 52°, and a spray speed of 0.6 m² / min. A layered application method is used. The first layer is 0.9 mm thick and allowed to stand for 2.5 hours to partially dry. The second layer is 1.3 mm thick, ensuring a total surface finishing layer thickness of 2.2 mm. After spraying, a special tool is used to lightly emboss the surface, with an embossing depth of 0.4 mm and an embossing spacing of 22 mm. After spraying, allow for 39 hours of natural curing, avoiding rain and external impacts during this period.

[0032] Sealing and waterproofing process: After the surface finish is cured, the corners, openings around doors and windows, joints of insulation boards, and damaged areas of the exterior wall of the high-rise building are sealed and waterproofed. A special waterproof sealant is used, with a tensile strength ≥1.8MPa, elongation at break ≥350%, and curing time ≤24 hours. During construction, first clean the dust and debris from the sealing area, then use a scraper to evenly fill the sealing area with the sealant, controlling the filling thickness to 2.2mm and the filling width to 18mm. After filling, smooth it with a scraper. After the sealant is applied, let it stand for 13 hours until it is completely cured. After curing, a water spray test is conducted to check for waterproofing. The water spray pressure is 0.11MPa, and the water spray time is 35 minutes. If there is no leakage after the test, it is considered qualified.

[0033] Finished product maintenance process: After the sealing and waterproofing treatment is qualified, finished product maintenance is carried out on the entire exterior wall of the high-rise building. The maintenance time is 76 hours. During the maintenance period, the ambient temperature is controlled at 5-35℃ and the relative humidity is controlled at 45-65%. During the maintenance period, it is forbidden to pile up debris or hang heavy objects on the wall surface, and it is forbidden to impact or grind the wall surface. The wall surface is inspected once a day to promptly find and deal with minor cracks, hollow areas and other problems on the wall surface. After the treatment, local maintenance is carried out again.

[0034] Finished Product Acceptance Process: After the finished product curing is completed, a full-process acceptance inspection is conducted, which consists of three stages: appearance inspection, performance testing, and document inspection. Appearance inspection uses a combination of visual inspection and measurement. The wall surface should be flat and smooth, with uniform texture, free from cracks, hollow areas, or peeling. The corners should be square, with a deviation ≤3.0mm. For performance testing, the external wall thermal conductivity should be 0.035W / (m·K), the insulation layer compressive strength 0.35MPa, the finish layer adhesion 0.55MPa, the impermeability should meet the requirement of no leakage after 30 minutes of water spraying, and the wind load resistance should be 0.8kPa. Document inspection verifies all records and test reports from the construction process, ensuring the documents are complete, standardized, and authentic. Upon successful acceptance, an acceptance report is issued.

[0035] After the construction of this embodiment is completed, the thermal insulation and finishing effect of the high-rise building's exterior wall is good. The insulation layer is firmly bonded to the base layer and the finishing layer, without cracking, hollowing, or peeling. The waterproof performance and wind load resistance performance meet the design requirements, and the construction process is simple and efficient.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
