Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an integrated construction method for high-altitude continuous profiled steel structure roofs. Background Technology

[0002] With the acceleration of industrialization and the booming development of the logistics industry, the demand for large-span, long-length single- or multi-story steel structure factories and warehouses is increasing. The roof spans of these buildings often exceed 30 meters, characterized by large spans, high waterproofing requirements, and tight construction schedules. Traditional profiled steel sheet roofing construction uses a factory prefabrication + on-site splicing model. Due to transportation size limitations, the length of a single steel structure panel is usually no more than 12 meters. This leads to the following disadvantages of the traditional construction method: 1. High risk of leakage: There are a large number of longitudinal joints in the roof. These joints are fixed with sealant and nails. Under the repeated action of structural deformation, material aging and wind load, they are prone to becoming weak points for leakage, resulting in high maintenance costs.

[0003] 2. Low construction efficiency: Multiple handling, alignment, splicing and edge locking are required on site, resulting in a large amount of high-altitude work, high dependence on manual labor, and difficulty in shortening the construction period.

[0004] 3. High material waste: The precast panels have a low degree of matching with the on-site dimensions, resulting in serious cutting waste; the panels are easily bent and damaged during transportation and hoisting.

[0005] 4. Significant safety risks: Long precast slabs are difficult to handle and position manually at heights, which can easily lead to falls from heights and falling objects.

[0006] 5. Many limitations: It has poor adaptability to complex roof shapes such as curved and sloped roofs, often requiring special customization or on-site secondary processing, making it difficult to control costs and quality.

[0007] To address the common challenges facing the industry and promote the upgrading of steel structure roofing construction technology towards industrialization, intelligence, and greening, there is an urgent need for a new construction technology that can achieve ultra-long single panels, on-site forming, one-time installation, and zero lap joints. Summary of the Invention

[0008] To address the problems in the existing technology, this invention discloses an integrated construction method for high-altitude continuous profiled steel structure roofs. This method uses continuous profiled equipment arranged on-site to directly process steel coils into ultra-long panels with the same slope length as the roof, and achieves synchronous transportation and installation.

[0009] The integrated construction method for high-altitude continuous profiled steel structure roofing includes the following steps: Step 1: Lay purlins on the steel beams and use the purlins to create the roof slope; Step 2: Install fixed supports on the steel beam and connect the purlins to the fixed supports with bolts; Step 3: Install gutters and lay load-bearing slabs; Step 4: Lay the intermediate layer above the bearing plate; Step 5: Process the continuous finished steel coils into whole plates of set size and shape using a high-altitude plate press. Step 6: Install and fasten the roof panels; Step 7: Install the light-transmitting panels; Step 8: Finishing and sealing the edges.

[0010] Preferably, in step 2, before installing the fixed supports, a theodolite is used to accurately lay out the roof to ensure that all supports are aligned longitudinally.

[0011] Preferably, in step 2, a special heat insulation pad is added before the support is installed to reduce heat conduction and protect the building structure.

[0012] Preferably, in step 2, after the support is installed, the straightness of the support is checked by pulling a line, and the allowable deviation is ≤2mm, to ensure that the subsequent roof panel installation proceeds smoothly.

[0013] Preferably, in step 4, the intermediate layer is laid in the following order from bottom to top: vapor barrier membrane, thermal insulation cotton, and waterproof membrane.

[0014] Preferably, in step 4, the insulation cotton and waterproof membrane are laid with staggered overlaps, and the joints are tight, which effectively improves the waterproof performance.

[0015] Preferably, in step 5, the specific construction process is as follows: 5.1 Hang the finished steel coil below the feed inlet of the high-altitude press machine, break the lifted steel coil, and send the steel coil into the high-altitude press machine; 5.2 Move the high-altitude pressure plate machine to the designated position, extend the outriggers, and raise the high-altitude pressure plate machine to the same height as the roof. 5.3. Select and match molds according to the design requirements, complete mold debugging, set the feeding speed, and ensure that the output plate shape meets the specifications; 5.4 Inspect the finished pressed sheet material and cut it according to the set length parameters, with a deviation of ≤±2mm; 5.5. Lay the pressed prefabricated roof panels on a small scale; 5.6 Adjust the position of the high-altitude pressure plate machine and repeat the above steps.

[0016] Preferably, in step 6, the specific construction process is as follows: 6.1 After the entire panel is in place, align the ribs with the fixed supports and fasten them precisely, overlapping them in the direction of the wind to ensure stability; 6.2 The straightness of the roof panels shall be tested using the string line method, and the deviation shall be ≤3mm / 10m; 6.3 Boards installed on the same day must be edge-locked using an edge-locking machine on the same day, with an edge-locking depth of ≥15mm to ensure a tight and secure fit.

[0017] The beneficial effects of this invention are as follows: 1. Safety: The boards are "pressed and installed simultaneously", eliminating the need for high-altitude handling of long boards; the equipment comes with a stable working platform, greatly reducing the risk of personnel falling from heights.

[0018] 2. In terms of quality: Zero longitudinal lap joints eliminate the main leakage path at the source; on-site molding as needed, the panel fit is extremely high, and the overall structural integrity, air tightness and water tightness are significantly better than traditional processes.

[0019] 3. In terms of efficiency: It achieves "zero cutting" of materials and "zero waiting" of processes, increasing construction speed by more than 30% and reducing overall costs by 10-15%. Attached Figure Description

[0020] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0021] Figure 1 This is a flowchart of the construction process of the present invention; Detailed Implementation To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] This invention discloses an integrated construction method for high-altitude continuous profiled steel structure roofing. This method has significant advantages in terms of functionality and construction method. Compared with traditional roofing construction methods, it exhibits outstanding technical and economic advantages in terms of construction period, quality, safety, and overall cost, mainly reflected in the following four aspects: 1. On-site whole-panel pressing and forming completely eliminates sloping lap joints. A high-altitude press machine is used to directly and continuously press roof panels onto the roof surface, with single panels reaching lengths of over 60 meters, achieving no longitudinal overlap along the slope. Compared to the traditional segmented panel on-site splicing process, this fundamentally eliminates the risk of leakage caused by aging of the overlap sealant, loose self-tapping screws, or thermal expansion and contraction, significantly improving the reliability and durability of roof waterproofing.

[0024] 2. Multi-layered composite structure with integrated construction, resulting in superior system performance. The innovative multi-layer composite enclosure system adopts a combination of profiled steel sheet bearing layer, waterproof membrane, insulation layer, and outer roof panel. Each functional layer is constructed simultaneously and tightly bonded, avoiding problems such as hollowing and water seepage caused by the disconnection of processes in traditional methods. This significantly improves the overall thermal insulation, waterproofing, and airtightness performance, meeting the high-standard industrial building enclosure requirements.

[0025] 3. Highly adaptable, suitable for large spans and complex roof shapes. This construction method is particularly suitable for single-story or multi-story steel structure factories, logistics warehouses, and other projects with spans exceeding 20 meters. It is well-suited for complex roof shapes such as curved, sloped, and hyperbolic roofs. On-site molding reduces transportation limitations and on-site cutting losses of precast panels, improves material utilization, and reduces waste rates.

[0026] 4. High degree of mechanization, significant safety and environmental benefits. The entire panel is directly formed and conveyed into place by a pressing machine, avoiding the risk of localized structural overload caused by concentrated stacking of roof panels in traditional construction. It significantly reduces manual handling and high-altitude assembly work, effectively reducing safety risks such as falls from heights and falling objects. At the same time, there is no wet work such as cutting or drilling on site or dust generation, resulting in low noise and less waste, which meets the requirements of green construction and civilized construction site.

[0027] This method is applicable to roofing projects of large-span buildings such as single-story or multi-story steel structure industrial plants, logistics warehouses, and stadiums, and is especially suitable for projects with high requirements for waterproofing, insulation, and construction period. Specifically, it is applicable to the following situations: 1. For roofs with large lengths or spans (single slope length ≥ 30m, structural span ≥ 20m), the transportation or hoisting of traditional profiled sheets is limited; 2. Projects requiring high waterproofing reliability, such as those with Class I or Class II waterproofing ratings, must avoid the risk of leakage at overlapping joints. 3. There are specific requirements for thermal insulation and energy-saving performance, and multi-layer composite enclosure structures are required to achieve high thermal performance; 4. Due to the tight construction schedule, mechanized and integrated construction methods are needed to shorten the roof sealing period; 5. Limited construction site conditions, such as urban centers, mountainous areas, or narrow areas, make it difficult to transport extra-long finished panels.

[0028] The core of this invention lies in the integrated construction system of "on-site continuous molding + multi-layer composite sealing enclosure". Its key technology relies on the mobile molding capability of the high-altitude press and the coordinated design of the roof system structure. The process flow diagram is as follows: Figure 1 As shown, the basic principle is as follows: 1. On-site continuous forming of whole sheets Using a high-altitude press deployed on the roof working surface, coiled metal sheets are continuously pressed into shape according to the actual building slope length and directly output to the installation position. Based on the theory of continuous cold bending of metal sheets, multiple precision roller sets are used to gradually cold bend the sheets, ensuring the geometric accuracy and mechanical properties of the sheet shape. Since the sheet length can be customized as needed (up to 60m or more), no longitudinal overlap can be achieved along the entire slope of the roof, eliminating leakage paths caused by sealing failure, thermal expansion and contraction, or negative wind pressure in traditional overlap joints.

[0029] II. Multi-layer composite enclosure system for coordinated sealing After completing the underlying structure, the final layer of interlocking roof panels, formed from a single sheet, is laid as the outermost protective layer, thus constructing a multi-layered composite enclosure system consisting of "corrugated steel sheet load-bearing layer + full-coverage polymer waterproof membrane + staggered joint insulation cotton + joint sealing treatment + outer interlocking roof panel". Each functional layer strictly adheres to the design principle of "combining prevention and drainage, with layered protection". 1. The profiled steel sheet bearing layer provides structural support and a construction base surface; 2. The waterproof membrane is fully laid to form a continuous and reliable main waterproof barrier; 3. The insulation cotton is laid in a staggered pattern to reduce thermal bridging and improve thermal performance; 4. All details such as eaves, gutters, and through-panel fittings are pre-sealed and reinforced; Finally, the entire roof panel, formed on-site by a high-altitude press, is used to cover and fix the entire structure, serving as the first line of defense against wind and rain erosion and ensuring the integrity, sealing, and absence of risk of leakage at any joints in the roof system.

[0030] III. Slope Finding and Drainage Guidance The roof slope is formed directly by the main structural purlins or secondary purlins (usually ≥5%), avoiding the risk of uneven thickness or water accumulation caused by relying on materials for slope formation. Combined with the precise positioning and slope control of drainage facilities such as gutters, siphon rainwater inlets / side-drain outlets, "rapid drainage and no water stagnation" are achieved, further reducing the probability of leakage.

[0031] The specific process flow of this method is as follows: Construction preparation → Surveying and setting out → Purlin installation → Fixed support installation and alignment → Gutter installation → Load-bearing plate laying → Vacuum barrier, insulation cotton, and waterproof membrane laying → High-altitude pressure plate machine positioning and whole panel processing → Roof panel installation and fastening → Skylight installation → Edge finishing and sealing → Adjustment and acceptance The key points of this method are as follows: 1. Installation of fixed supports 1.1 Before installing the fixed supports, a theodolite should be used to accurately lay out the roof to ensure that all supports are aligned longitudinally.

[0032] 1.2. Before installing the support, a special heat insulation pad should be added to reduce heat conduction and protect the building structure.

[0033] 1.3 Each support is symmetrically fixed with two self-tapping screws to ensure its stability; the installation direction must be consistent with the length of the plate to avoid wear on the plate ribs.

[0034] 1.4 After installation, check the straightness of the supports by pulling a line. The allowable deviation is ≤2mm to ensure the smooth installation of the subsequent roof panels.

[0035] 2. Intermediate layer laying 2.1 Lay the vapor barrier membrane, thermal insulation cotton and waterproof membrane in sequence. Each layer of material should be fixed as it is laid to prevent displacement or wind damage.

[0036] 2.2 When laying thermal insulation cotton and waterproof membrane, staggered overlaps are used, and the joints are tight, which effectively improves waterproof performance.

[0037] 2.3. Key areas such as eaves and ridges need to be sealed and finished to ensure there is no risk of leakage.

[0038] 3. High-altitude pressure plate machine construction 3.1 Steel coil feeding: Hang the finished steel coil below the feed inlet of the press machine, break the lifted steel coil, and feed the steel coil into the press machine; 3.2 Equipment Positioning: Move the high-altitude press machine to the designated position, extend the outriggers, and use hydraulic cylinders to lift the press machine to the same height as the roof.

[0039] 3.3 Mold Adjustment: Select and match molds according to the design requirements, complete mold adjustment, set the feeding speed, and ensure that the output plate shape meets the specifications (e.g., YXB65-170-510, set the feeding speed to 5-8m / min).

[0040] 3.4. Outgoing Inspection: Inspect the finished pressed boards. After on-site verification, continue production and cut the materials according to the set length parameters, with a deviation of ≤±2mm.

[0041] 3.5. Lay the pressed finished roof panels on a small scale.

[0042] 3.6 Adjust the position of the press machine and repeat the above steps.

[0043] 4. Roof panel installation 4.1 After the entire plate is in place, align the ribs with the fixed supports and fasten them precisely, overlapping them in the direction of the wind to ensure stability.

[0044] 4.2 The straightness of the roof panels shall be tested by the string line method, and the deviation shall be ≤3mm / 10m.

[0045] 4.3 Boards installed on the same day must be edge-locked using an edge-locking machine on the same day, with an edge-locking depth ≥15mm to ensure a tight fit without loosening; 4.4 Gutters and Edge Finishing Gutter installation: Stainless steel gutters need to be installed on the roof panels in advance and a water tightness test should be conducted after welding to ensure there is no leakage.

[0046] Detail handling: Edges such as eaves and gable walls must be securely installed and well-sealed, with the folded edges facilitating drainage. Overflow outlets should be constructed simultaneously with gutters, with precise pre-drilled holes in the parapet wall, which should be properly sealed to prevent electrochemical corrosion.

[0047] The materials and equipment required for this method are as follows: 1. Main materials 2. Main equipment The quality control of this method is as follows: 1. Implementation Standards 2. Key Quality Requirements and Inspection Methods 3. Technical Measures and Management Methods 3.1 Technical Measures 3.1.1 A high-altitude press machine is used for continuous on-site forming to achieve continuous forming of the whole board (length ≥ 60m), eliminating the risk of leakage at the lap joints; 3.1.2 Implement the "multi-layer composite enclosure" process, with staggered laying of thermal insulation cotton, full coverage of waterproof membrane, and interlocking and locking of the outer roof panels to ensure system sealing; 3.1.3 Key nodes (eaves, gutters, skylights) are treated with multi-layer sealing. In addition to self-adhesive waterproof membrane, special sealant and finished flashing are used.

[0048] 3.2 Management Methods 3.2.1 Full-process information management: Utilize mobile terminal APP to realize real-time uploading and archiving of process self-inspection, mutual inspection and special inspection data, and establish traceable electronic quality archives.

[0049] 3.2.2 First-piece sample guidance: Before large-scale construction of the roof, select a standard unit for "first-piece" installation, and conduct joint acceptance of the pressure plate accuracy, edge locking quality and edge finishing effect to unify construction standards.

[0050] 3.2.3 Seasonal Construction Support: Develop specific plans to address windy and rainy weather in certain regions. Automatic shutdown will be implemented if wind speeds exceed the equipment's safe operating level. During the rainy season, immediate covering and protection measures will be taken for the already laid insulation and waterproofing layers.

[0051] 3.2.4 Third-party testing and verification: For key processes such as the straightness of the fixed support installation, the interlocking strength of the roof panel, and the welding of the gutter, a qualified third-party testing agency can be commissioned to conduct sampling tests to verify the quality with data.

[0052] The safety precautions for this construction method are as follows: 1. Safety Measures 1.1 Comprehensive Protection System for High-Altitude Operations 1.1.1 Personnel Protection: All workers must wear 100% double-hook five-point safety harnesses, with the harnesses being attached high and used low. The safety harness attachment points should be independent of the equipment and preferably located on pre-installed permanent or temporary lifelines on the roof.

[0053] 1.1.2 Area Protection: Standardized guardrails no less than 1.2m high shall be installed at eaves, gutters, and other edge locations, and dense safety nets shall be attached. A horizontal safety net shall be installed in the corresponding area below the roof to form a double fall protection barrier of "high altitude + ground".

[0054] 1.1.3 Passage Protection: Set up a safe passage for personnel passage and material transportation. The passage should be stable, non-slip, and equipped with continuous handrails.

[0055] 1.2 Safety Management of Special Equipment and Construction Machinery 1.2.1 Special Management of High-Altitude Press Machines: A specific plan must be prepared for the installation, lifting, and relocation of the equipment, and the operation must be carried out by a professional team. A safety inspection must be conducted before each day's operation, with a focus on the hydraulic system, fasteners, safety limit devices, and grounding.

[0056] 1.2.2 Lifting Operation Management: For lifting materials such as steel coils and gutters, clear signals and instructions are required, and no one is allowed to stand under the load. Lifting slings must be inspected before use to ensure they are undamaged.

[0057] 1.3 Construction Environment and Electrical Safety 1.3.1 Severe Weather Response: Establish an early warning mechanism in conjunction with the local meteorological department. When the wind speed is ≥ level 6 (i.e., 10.8 m / s), the installation of high-altitude pressure plates and roof panels must be stopped, and the equipment must be reinforced or evacuated to a safe area.

[0058] 1.3.2 Temporary power supply: Strictly implement the TN-S grounding protection system and three-level power distribution and two-level protection. Cables for rooftop mobile equipment must be special rubber-sheathed cables that are resistant to crushing and dragging, and must be laid overhead.

[0059] 2. Safety Warning Items 2.1 Wind Warning The system monitors meteorological data in real time and automatically shuts down when the wind force is ≥6. Work can only resume when the wind force drops to below 5.

[0060] 2.2 Equipment Anomaly Early Warning If any abnormal noise, excessive vibration, or abnormal seam gap (>0.5mm) occurs during operation, stop the machine immediately for inspection. Operation with defects is strictly prohibited.

[0061] 2.3 Early Warning of Personnel Behavior If safety belts are not fastened, work is overloaded, or materials are thrown in violation of regulations, the on-site safety officer shall immediately stop and record the violation to ensure compliance.

[0062] The accompanying environmental protection measures for this method are as follows: 1. Environmental protection construction measures 1.1 Noise and Dust Control 1.1.1 Source Control: The high-altitude platen press itself is a low-noise device. Angle grinders and other cutting tools are prohibited on-site to eliminate metal cutting dust and noise at the source.

[0063] 1.1.2 Process Monitoring: Noise monitoring points shall be set up at the boundary of the construction area to ensure that noise emissions are ≤70dB during the day and ≤55dB at night (if nighttime construction is required). Lightweight soundproof barriers shall be set up in the processing area.

[0064] 1.2 Waste Resource Utilization Management 1.2.1 Classified Recycling: Establish a dedicated waste recycling area to classify and store discarded steel coil cores, packaging materials, and small amounts of metal scraps.

[0065] 1.2.2 Waste Reduction: Through precise calculations and on-site forming, the steel loss rate is reduced to less than 1%, thus reducing solid waste generation at the source. Scrap materials such as insulation cotton can be used to fill gaps in pipe penetrations, achieving reuse.

[0066] 1.3 Water pollution prevention and control During roof construction, gutters will be temporarily sealed to prevent construction debris from entering the drainage system. Small amounts of wastewater generated from cleaning tools will be treated by sedimentation before being discharged.

[0067] 1.4 Energy-saving measures Highly efficient and energy-saving high-altitude pressure plate machines and lighting equipment were adopted. Construction organization was optimized to reduce energy consumption during equipment idling.

[0068] 2. Civilized Construction Measures 2.1 Construction Time Control High-noise operations (such as pressing and cutting) are strictly prohibited between 22:00 and 6:00 the next day to avoid disturbing residents; 2.2 Transportation Management 100% of transport vehicles are covered with tarpaulins, and tires and chassis are cleaned before leaving the site to prevent mud from being carried onto the road. 2.3 On-site cleaning Clean the work area after each day's work to keep the site clean and free of spilled materials and oil stains.

[0069] The benefit analysis of this method is as follows: 1. Economic benefits This construction method significantly reduces material consumption, transportation and hoisting costs, and construction period through "on-site whole-plate forming and zero-overlap joint" technology, resulting in outstanding overall economic benefits. 1.1 Optimization of Material Loss Rate Traditional profiled steel sheets suffer from a loss rate as high as 5% due to on-site splicing and cutting; this construction method uses a high-altitude pressing machine for continuous forming, achieving no overlap along the entire length of the roof, reducing the loss rate to less than 1%.

[0070] Taking a 15,600m² roof as an example, the traditional method results in a loss of 780m² (approximately 195,000 yuan), while this method only results in a loss of 156m² (approximately 39,000 yuan), saving an average of 156,000 yuan in material costs per project per year.

[0071] 1.2 Reduced transportation and hoisting costs The length of a single panel can reach over 60m, avoiding multiple transportations (usually requiring 3-5 trips) and hoisting (each panel needs to be hoisted independently) required in traditional processes. Transportation and hoisting costs are reduced by 60% compared to traditional methods.

[0072] 1.3 Reduction of construction period and management costs The construction period for roofing is shortened by more than 30% compared to traditional methods. Taking the Shandong Jianzhu University Student Service Center project as an example, the construction period was shortened by 10 days, reducing labor, machinery rental, and management coordination costs by approximately 60,000 yuan, and management costs decreased by 25%.

[0073] 1.4 Low life-cycle cost Because the waterproofing reliability is greatly improved, the cost of later maintenance is basically eliminated. Taking a 10,000 square meter roof as an example, the annual maintenance cost for leakage using traditional methods is about 30,000 to 50,000 yuan, while this method can be regarded as zero.

[0074] 1.5 Advantages in Insurance Costs The reduction in construction safety risks may result in more favorable engineering insurance rates.

[0075] 2. Environmental protection and energy conservation benefits This construction method strictly adheres to the "Green Building Evaluation Standard" (GB / T50378-2019), achieving environmental protection and energy conservation throughout the entire construction process. 2.1 Contribution of Green Construction There was no welding, no open flame, and very little cutting on site, which met the green construction requirements of "four savings and one environmental protection".

[0076] 2.2 Carbon emission reduction benefits The comprehensive energy savings resulting from reduced material consumption, fewer transport trips, and shorter construction periods translate to carbon emission reductions of tens of tons per project.

[0077] 2.3 Resource Cycle The steel itself is 100% recyclable, which aligns with the concept of a circular economy.

[0078] 2.4 Noise and Dust Control Dust covers and noise reduction barriers were set up on site, with construction noise ≤75dB during the day and ≤55dB at night, reducing noise by 30% and dust by 87% compared to traditional cutting processes (noise 85dB, dust 2.0mg / m³).

[0079] 2.5 Waste Reduction The roof panels are processed according to the slope length, reducing vertical overlap cutting and significantly reducing metal waste.

[0080] 2.6 Energy Saving Contribution The multi-layer composite enclosure system (insulation cotton + waterproof membrane) improves the thermal performance of the roof, and the heat transfer coefficient is reduced by 15% compared with the traditional process.

[0081] 3. Social benefits 3.1 Promoting technological progress in the industry: It provides a brand-new solution for steel structure roofing projects and promotes the transformation and upgrading of construction technology from "on-site assembly" to "on-site manufacturing".

[0082] 3.2 Enhance corporate brand image: Projects constructed using this method, with their superior waterproof performance and aesthetically pleasing overall effect, serve as a window to showcase the company's technological strength.

[0083] 3.3 Safeguarding people's livelihood and safety: It is especially suitable for buildings with extremely high requirements for moisture-proof and leak-proof, such as warehouses, logistics facilities, food and drug factories, ensuring the safety of social material storage.

[0084] 3.4 Aligning with national strategies and industry concepts: Meeting the building standards for "good houses," emphasizing "high quality, long lifespan, and good experience"; promoting the transformation of industrial buildings towards green and industrialization, and contributing to the "dual carbon" goals.
