Description

Technical Field

[0001] This invention relates to the field of architectural observation deck construction technology, and in particular to a method for constructing and decorating complex, nonlinear, multi-curved high-altitude observation decks. Background Technology

[0002] The design of high-altitude restaurants faces numerous technical challenges and design contradictions, including complex structural forms, limited building space, high difficulty in constructing ultra-long and ultra-wide eaves spaces, and precision requirements and processing difficulties for various irregular components such as single-curved and double-curved ultra-high inclined glass curtain walls, multi-curved GRC cladding panels, and spatial trusses.

[0003] The building has a complex structural form, especially its hyperbolic ground-level roof and free-form curves along its edges. This requires strict control over the shaping effect. On the one hand, this complex nonlinear multi-curved surface design poses challenges to the stability and safety of the structure. On the other hand, the on-site construction level and existing design experience are insufficient to meet such high standards. Therefore, in-depth research and experimentation are needed to meet the shaping requirements of this flexible ground-level building.

[0004] High-precision construction techniques and special material requirements are also major challenges, especially how to handle irregularly shaped components, such as single-curved and double-curved ultra-high inclined glass curtain walls and multi-curved GRC cladding panels. These require very precise processing and positioning. In addition, due to the limited building space, the ultra-long and ultra-wide eaves space also poses a great challenge to the structural construction. In terms of design, the high-altitude restaurant also needs to solve how to maximize the view and aesthetics under the constraints, while also considering environmental sustainability and ecological compatibility. Summary of the Invention

[0005] To achieve the above objectives, this invention provides a method for constructing and decorating complex nonlinear multi-curved high-altitude observation decks.

[0006] A method for constructing and decorating a complex, nonlinear, multi-curved high-altitude observation deck includes the following steps:

[0007] S1: Construction of landscape stone paving, micro-planting, hyperbolic accessible roof;

[0008] S2: Installation of fair-faced concrete GRC panels under the eaves of irregularly shaped, extra-long, cantilevered, complex curved surfaces;

[0009] S3: Construction of ultra-high inclined irregular glass curtain wall in confined space under eaves;

[0010] S4: Construction of a single-curved, stacked, wingspan-shaped dry-hanging stone staircase;

[0011] This method utilizes BIM technology along with total station and engraving machine technology to conduct detailed measurements, design refinement, and construction control for each part. By combining the BIM model with the on-site 3D scanning results and GPS measuring instruments, it ensures that the building elements accurately correspond to their theoretical models and achieve integration with the natural environment.

[0012] Furthermore, S1 specifically includes:

[0013] S11: Use a GPS measuring instrument to accurately mark points in the predetermined area, with each point spaced no more than 1 meter apart;

[0014] S12: At each GPS calibration point, make a 10cm x 10cm x 10cm cement mortar block to mark the specific elevation of that point;

[0015] S13: Use a laser level to connect the various cement mortar elevation points to form an accurate three-dimensional network, with the height difference of the roof not exceeding 1cm;

[0016] S14: Based on the three-dimensional network, the "irregular landscape stone paving" technique is adopted, using natural stone slabs with a size of not less than 30cm x 30cm for paving. All stone slabs have a uniform thickness of 3cm and the edges are treated with a slight arc.

[0017] S15: Leave a 1cm-2cm gap between the stone pieces, fill the gap with high-quality soil, and control the pH value of the soil between 6 and 7.

[0018] S16: After the soil is filled, carry out micro-planting, select cold-resistant, drought-resistant and trampling-resistant plants, and plant them at a spacing of no more than 10cm x 10cm;

[0019] S17: After planting, use a drip irrigation system for irrigation, with the spacing between each drip point not exceeding 50cm, to ensure that the entire micro-planting area receives uniform water;

[0020] S18: Conduct 30 days of observation and maintenance on the entire landscape stone paving micro-planted hyperbolic accessible roof to ensure good plant growth and perform necessary pruning and fertilization.

[0021] Furthermore, in the construction of the landscape stone paving micro-planting hyperbolic accessible roof in S1, Rhino software is used for detailed design, and the material list is exported using the software.

[0022] Furthermore, the detailed design using Rhino software specifically includes:

[0023] The first three-dimensional model of the pre-designed hyperbolic accessible roof is carried out using Rhino software to ensure that each surface, angle and joint meets the design requirements. The first three-dimensional model includes the division of landscape pebbles and soil-filled micro-planting areas. Modeling algorithms are applied in Rhino software to simulate the physical characteristics of landscape pebbles and micro-planting plants, including load distribution, water permeability and heat conduction.

[0024] Within the Rhino software, simulation analysis is performed to determine the optimal stone cutting scheme and plant density. The material and cost estimation functions of the Rhino software are then used to export a bill of materials.

[0025] Furthermore, the 3D model and material list generated by the Rhino software are exported in a file format compatible with the construction site for total station positioning and material procurement. The material list not only lists the quantity of required materials, but also classifies and recommends plant seeds according to regional and seasonal needs.

[0026] Furthermore, S2 specifically includes:

[0027] S21: Prefabrication design and optimization. In the BIM software environment, a second three-dimensional model is created for the pre-designed irregular, ultra-long, cantilevered, complex curved eaves. This second three-dimensional model includes the specific dimensions, shape, and pre-designed installation location of the GRC panels.

[0028] S22: Simulation and Analysis. Using the structural and physical simulation tools built into the BIM software, the structural stability, wind pressure, and heat conduction of the GRC slab in the cantilever state are simulated and analyzed. After the model is confirmed to be correct, the required GRC slab production data, including the slab size, shape, cutting angle, and mounting hole position, are exported from the BIM software.

[0029] S23: Total station measurement. At the construction site, a total station is used to accurately measure the predetermined installation position of the GRC panels and compare it with the BIM model data to ensure data consistency. Based on the production data exported from the BIM software, the GRC panels are prefabricated. During the production of GRC panels, a carving machine is used to open the mold for each panel to improve the processing accuracy of the product.

[0030] S24: On-site positioning and installation. After the GRC panels arrive at the construction site, a total station is used for positioning and measurement. By matching the data with the BIM model, it is ensured that each GRC panel can be accurately installed in the predetermined position.

[0031] Furthermore, S3 specifically includes:

[0032] S31: Pre-modeling and analysis. Using BIM software, a third-dimensional model of the expected ultra-high inclined irregular glass curtain wall is created, and the structural stability and wind pressure simulation are performed using the built-in analysis tools of BIM.

[0033] S32: Construction plan and bill of materials. Export a complete bill of materials from the BIM model, including the size, shape and thickness of the glass panels. Based on the BIM model, plan the construction steps and sequence.

[0034] S33: On-site preparation. At the construction site, use a total station to perform a 3D scan to obtain on-site measurement data. Compare the data obtained by the total station with the BIM model to check whether adjustments are needed.

[0035] S34: Spatial positioning and installation. In the confined space under the eaves, an auxiliary hoist system is set up to lift and position the glass panel. Before the auxiliary hoist lifts the glass panel to the predetermined position, a total station is used to measure again to ensure accurate installation. Based on the data from the total station and the BIM model, the auxiliary hoist is used to install the glass panel to the predetermined position.

[0036] S35: Use Rhino software to perform detailed design of curtain wall glass, keel and connectors, and establish a curtain wall construction model for exporting material lists, extracting coordinate values ​​and guiding on-site curtain wall procurement, processing and installation.

[0037] Furthermore, S4 specifically includes:

[0038] S41: Design and simulation. Using professional BIM software, the fourth and third-dimensional model of the single-curved stacked wingspan dry-hanging stone staircase is carried out. Within the BIM environment, the geometry of the stone is analyzed and verified in detail to ensure that it conforms to the overall design and structural requirements.

[0039] S42: On-site data collection. Using Leica 3D scanner equipment, real-time data collection is carried out on the construction site. The 3D scan data is imported into the BIM model for data correction and verification.

[0040] S43: Export stone geometry dimensions. Export the accurate geometric dimensions of the stone from the validated BIM model. Based on the geometric dimensions, develop the stone processing specifications, including cutting angles and area.

[0041] S44: Factory production, in accordance with the exported process specifications and geometric dimensions, uses CNC machine tools to cut and process the stone in the factory. After processing, a laser scanner is used to inspect the size and shape.

[0042] S44: On-site installation and verification. Use a total station or similar equipment to set up points on-site to determine the accurate location where the stone should be installed. Based on the points and BIM model data, dry-hang the stone. After installation, perform a 3D scan on-site and compare the results with the BIM model to ensure the accuracy of the installation.

[0043] Furthermore, in the construction of the single-curved, overlapping, wingspan-shaped dry-hanging stone staircase, Rhino software was used for detailed design and to export the material list.

[0044] The beneficial effects of this invention are:

[0045] This invention, with its irregular landscape stone paving and gap-filling micro-planting construction technology, significantly improves the construction quality and landscape effect of accessible roofs. By precisely controlling the formation of the cement mortar bonding layer, it not only reduces the difficulty of stone paving and improves efficiency, but also solves the problem of flatness. The gap-filling micro-planting technology further strengthens the integration of the roof with the natural environment, achieving a high degree of consistency with the design goals and the landscaping of the landscape, providing strong support for the harmonious coexistence of high-rise restaurants and the natural environment.

[0046] This invention relates to a construction technology for fair-faced concrete (GRC) cladding panels under irregularly shaped, ultra-long, cantilevered, complex curved eaves. By integrating BIM, total station, and engraving machine technologies, it significantly improves production and construction efficiency while reducing overall construction difficulty and cost. This integrated technology ensures the high precision and quality of the cladding panel curtain wall system, meeting the design requirements for precise control of the field of vision and landscape.

[0047] This invention utilizes BIM+total station (3D scanning) positioning technology and spatial positioning installation method to successfully solve the installation problem of irregularly shaped glass curtain walls in confined spaces, improves installation accuracy and reduces construction difficulty. For staircase construction, the single-curved overlapping wing-shaped dry-hanging stone staircase construction technology is adopted, which reduces costs and improves construction efficiency.

[0052] like Figure 1 As shown, the construction method for a complex nonlinear multi-curved high-altitude observation deck includes the following steps:

[0053] S1: Construction of landscape stone paving, micro-planting, hyperbolic accessible roof;

[0054] S2: Installation of fair-faced concrete GRC panels under the eaves of irregularly shaped, extra-long, cantilevered, complex curved surfaces;

[0055] S3: Construction of ultra-high inclined irregular glass curtain wall in confined space under eaves;

[0056] S4: Construction of a single-curved, stacked, wingspan-shaped dry-hanging stone staircase;

[0057] This method utilizes BIM technology along with total station and engraving machine technology to conduct detailed measurements, design refinement, and construction control for each part. By combining the BIM model with the on-site 3D scanning results and GPS measuring instruments, it ensures that the building elements accurately correspond to their theoretical models and achieve integration with the natural environment.

[0058] This method is particularly suitable for high-altitude observation decks with complex nonlinear multi-curved surfaces, solving several technical problems that traditional methods cannot address, and achieving a high degree of integration and visual effect between architectural decoration and the natural environment.

[0059] S1 specifically includes:

[0060] S11: Use a GPS measuring instrument to accurately mark points in the predetermined area, with each point spaced no more than 1 meter apart;

[0061] S12: At each GPS calibration point, make a 10cm x 10cm x 10cm cement mortar block to mark the specific elevation of the point. The cement mortar mix ratio is water:cement:sand = 0.5:1:2.

[0062] S13: Use a laser level to connect the various cement mortar elevation points to form an accurate three-dimensional network, with the height difference of the roof not exceeding 1cm;

[0063] S14: Based on the three-dimensional network, the "irregular landscape stone paving" technique is adopted, using natural stone slabs with a size of not less than 30cm x 30cm for paving. All stone slabs have a uniform thickness of 3cm and the edges are treated with a slight arc.

[0064] S15: Leave a 1cm-2cm gap between the stone pieces, fill the gap with high-quality soil, and control the pH value of the soil between 6 and 7.

[0065] S16: After the soil is filled, carry out micro-planting, select cold-resistant, drought-resistant and trampling-resistant plants, and plant them at a spacing of no more than 10cm x 10cm;

[0066] S17: After planting, use a drip irrigation system for irrigation, with the spacing between each drip point not exceeding 50cm, to ensure that the entire micro-planting area receives uniform water;

[0067] S18: Conduct 30 days of observation and maintenance on the entire landscape stone paving micro-planted hyperbolic accessible roof to ensure good plant growth and carry out necessary pruning and fertilization;

[0068] The above specific technical solutions not only solved the flatness problem of the roof surface, but also ensured the high degree of integration between the roof surface and the natural environment. The solution used precise measurement and control technology to ensure the accuracy and feasibility of all engineering activities.

[0069] In the construction of the landscape stone paving micro-planting hyperbolic accessible roof of S1, Rhino software was used for detailed design, and the material list was exported using the software.

[0070] The detailed design using Rhino software specifically includes:

[0071] The first three-dimensional model of the pre-designed hyperbolic accessible roof is carried out using Rhino software to ensure that each surface, angle and joint meets the design requirements. The first three-dimensional model includes the division of landscape pebbles and soil-filled micro-planting areas. Modeling algorithms are applied in Rhino software to simulate the physical characteristics of landscape pebbles and micro-planting plants, including load distribution, water permeability and heat conduction.

[0072] Within the Rhino software, simulation analysis is performed to determine the optimal stone cutting scheme and planting density. Using Rhino's material and cost estimation capabilities, a bill of materials is exported, which will include the various types and sizes of landscape pebbles, soil, micro-plant seeds, irrigation system components, and other necessary construction materials.

[0073] The 3D model and material list generated by Rhino software can be exported in a file format compatible with the construction site for total station positioning and material procurement. The material list not only lists the quantity of required materials, but also classifies and recommends plant seeds according to regional and seasonal needs.

[0074] After construction was completed, the completed hyperbolic accessible roof was scanned and compared with the model again using Rhino software to ensure that the construction results were within the error range of the design plan.

[0075] S2 specifically includes:

[0076] S21: Prefabrication design and optimization. In the BIM software environment, a second three-dimensional model is created for the pre-designed irregular, ultra-long, cantilevered, complex curved eaves. This second three-dimensional model includes the specific dimensions, shape, and pre-designed installation location of the GRC panels.

[0077] S22: Simulation and Analysis. Using the structural and physical simulation tools built into the BIM software, the structural stability, wind pressure, and heat conduction of the GRC slab in the cantilever state are simulated and analyzed. After the model is confirmed to be correct, the required GRC slab production data, including the slab size, shape, cutting angle, and mounting hole position, are exported from the BIM software.

[0078] S23: Total station measurement. At the construction site, a total station is used to accurately measure the predetermined installation position of the GRC panels and compare it with the BIM model data to ensure data consistency.

[0080] During the GRC panel installation process, BIM technology was continuously used for real-time monitoring. Any errors were immediately adjusted to ensure maximum consistency with the design model. For acceptance and documentation, after all GRC panels were installed, a final total station measurement and comparison with the BIM model were conducted to ensure that the construction results were within the allowable error range of the design scheme. Simultaneously, complete construction documentation, including all construction details and material usage, was generated.

[0081] The above steps ensure that the fair-faced concrete GRC slabs under the irregularly shaped, extra-long, cantilevered, complex curved eaves are accurately and efficiently installed in the predetermined positions, achieving high precision, high efficiency, and high sustainability. The embodiment of this claim has significant technical advantages and practical value compared to traditional installation methods.

Before the auxiliary hoist lifts the glass panel to the predetermined position, a total station is used to measure again to ensure accurate installation. Based on the data from the total station and the BIM model, the auxiliary hoist is used to install the glass panel to the predetermined position.

[0087] S35: Use Rhino software to perform detailed design of curtain wall glass, keel and connectors, and establish a curtain wall construction model for exporting material lists, extracting coordinate values ​​and guiding on-site curtain wall procurement, processing and installation.

After all glass panels were installed, a final total station measurement and comparison with the BIM model were performed to ensure that everything was within the predetermined error range, and a complete construction document including all construction details and material usage was generated.
