Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a construction method for a hyperbolic irregular building. Background Technology

[0002] With social development, steel structure buildings have gradually become a new type of building system. Due to their high strength, lightweight, plasticity, and flexibility, they are gradually replacing traditional concrete structures and becoming a trend in architectural development. Steel structures are widely used in buildings with special requirements for structural appearance and space, such as stadiums, airports, and railway stations. They often use spatial steel tube structures to achieve unique design effects, and these structures often contain complex spatial twists and multi-angle connections.

[0003] However, the installation and positioning of spatial steel tubular structures are quite challenging, especially in hyperbolic irregular structures where strict aesthetic requirements exist. These buildings typically also require curtain wall systems, but the complexity of the irregular steel tubular structure presents even greater challenges to their installation. Currently, there is a lack of effective construction methods for such hyperbolic irregular structures, leading to increased construction difficulty, difficulty in effectively addressing complex design and construction needs, and challenges in ensuring project efficiency and precision.

[0004] Therefore, there is an urgent need to propose a construction method for hyperbolic irregular buildings to solve the above-mentioned technical problems. Summary of the Invention

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] This invention provides a construction method for hyperbolic irregular buildings, comprising:

[0008] Based on the design drawings, three-dimensional models of the main steel structure and curtain wall system of the hyperbolic irregular building are established respectively. The curtain wall system includes curtain wall keel and curtain wall panels.

[0009] The three-dimensional model of the main steel structure and the three-dimensional model of the curtain wall system are combined to form an overall model.

[0010] The main steel structure and the curtain wall system are fabricated based on the overall model.

[0011] After processing and manufacturing, the curtain wall keel is first assembled to the main steel structure. After assembly, it is hoisted as a whole, and then the curtain wall panels are installed to the curtain wall keel.

[0012] In some embodiments, the curtain wall keel includes a main keel and a secondary keel;

[0013] Based on the design drawings, three-dimensional models of the main steel structure and curtain wall system of the hyperbolic irregular building were created, specifically including:

[0014] The main steel structure is optimized into a straight line, the main keel is optimized into a single curve, and the secondary keel is optimized into a straight line. Based on the optimization results, a three-dimensional model of the main steel structure and the curtain wall keel is generated.

[0015] In some embodiments, the three-dimensional model of the main steel structure and the three-dimensional model of the curtain wall system are combined to form an overall model, including:

[0016] After generating a three-dimensional model of the main steel structure and the curtain wall keel based on the optimization results, the positioning points of the main steel structure, the main keel and the secondary keel are determined and verified through cross-sectional views at different elevation positions;

[0017] The relative positional relationship between the curtain wall system and the main steel structure is determined based on the positioning points of the main steel structure, the main keel, and the secondary keel.

[0018] Potential collision points are identified using collision detection tools, and the 3D model of the main steel structure or the 3D model of the curtain wall system is adjusted based on the collision detection results.

[0019] In some embodiments, the main steel structure is fabricated based on the overall model, including:

[0020] The measurement points of each component in the main steel structure are determined according to the on-site construction sequence and actual on-site working conditions, and the measurement points are fed back to the overall model so that the measurement points are converted into processing coordinates;

[0021] The main steel structure is processed according to the processing coordinates;

[0022] After processing is completed, the processing coordinates of each component in the main steel structure are remeasured, and the remeasured data is fed back to the three-dimensional model of the main steel structure to calculate the deviation of the processing coordinates.

[0023] In some embodiments, the main steel structure is processed according to the processing coordinates, and after processing is completed, the process further includes:

[0024] Three-dimensional scanning technology was used to measure each component in the main steel structure, and the measurement results were imported into the three-dimensional model of the main steel structure for mold assembly.

[0025] In some embodiments, the curtain wall system is fabricated based on the overall model, including:

[0026] The three-dimensional model of the curtain wall keel in the curtain wall system is adjusted based on the measured data of the main steel structure, and paperless drawing and material cutting are performed based on the adjusted model.

[0027] The curtain wall keel is bent using a bending device;

[0028] The accuracy of the curtain wall keel after bending was checked using 1:1 keel bending drawings.

[0029] In some embodiments, after processing and manufacturing, the curtain wall keel is first assembled to the main steel structure, and then hoisted as a whole after assembly, specifically including:

[0030] A three-dimensional scan is performed on the connection structure of the main steel structure, and the three-dimensional coordinates of the connection structure are determined. The three-dimensional coordinates are then fed back to the overall model for comparison and adjustment.

[0031] The curtain wall keel is assembled into multiple first units, and the multiple first units are assembled with the main steel structure. The assembled curtain wall keel and the main steel structure are then hoisted together as a whole.

[0032] In some embodiments, the curtain wall keel is assembled into multiple first units, the multiple first units are assembled with the main steel structure, and after the assembled curtain wall keel and the main steel structure are hoisted as a whole, the method further includes:

[0033] The actual measurement points of the main steel structure and the curtain wall keel after hoisting were re-measured. At the same time, the main steel structure and the curtain wall keel after hoisting were 3D scanned, and the measurement results were imported into the 3D model of the main steel structure and the 3D model of the curtain wall system for model merging.

[0034] In some embodiments, installing the curtain wall panel onto the curtain wall keel specifically includes:

[0035] The curtain wall panels are assembled into multiple second units, and the multiple second units are sequentially installed onto the curtain wall keel.

[0036] In some embodiments, after the curtain wall system is installed, it further includes:

[0037] The facade of the curtain wall system is subjected to a 3D scan, and the scan data is fed back to the original overall model for comparison. Adjustments or repairs are made based on the comparison results.

[0038] The beneficial effects of this invention are:

[0039] The construction method for hyperbolic irregular buildings provided by this invention achieves precise expression and coordination of the building's complex geometry by establishing a three-dimensional model of the main steel structure and curtain wall system in the early stages of construction. First, the three-dimensional model, created through detailed design, accurately reproduces the geometric features of the hyperbolic irregular structure. Second, the three-dimensional modeling of the main steel structure and curtain wall system effectively improves the synergy between different systems, reduces on-site adjustments and errors, and makes processing and installation more efficient and precise. Due to the accuracy of the three-dimensional model, the entire construction process is better controlled, helping to reduce construction difficulty, improve project efficiency and construction precision, and ensure the aesthetics and structural stability of the hyperbolic irregular building. Furthermore, pre-assembling the curtain wall frame and main steel structure as a single unit allows for high-precision assembly on the ground, avoiding the complexity and safety risks of installing components one by one at height, significantly improving construction efficiency and installation precision, and greatly ensuring the accuracy of subsequent curtain wall panel installation.

[0058] like Figure 1 As shown, the construction method for hyperbolic irregular buildings provided in this embodiment includes:

[0059] S1. Based on the design drawings, establish three-dimensional models of the main steel structure and curtain wall system of the hyperbolic irregular building. The curtain wall system includes the curtain wall keel and the curtain wall panels.

[0060] S2. Combine the three-dimensional model of the main steel structure and the three-dimensional model of the curtain wall system to form an overall model.

[0061] S3. Fabricate and manufacture the main steel structure and curtain wall system based on the overall model;

[0062] S4. After processing and manufacturing, the curtain wall keel is first assembled to the main steel structure. After assembly, it is hoisted as a whole, and then the curtain wall panels are installed to the curtain wall keel.

[0063] Among them, the three-dimensional model can be a BIM model (Building Information Modeling), which refers to a digital three-dimensional model created based on architectural design drawings, including shape, materials, connection methods, etc.

[0064] The construction method for hyperbolic irregular buildings provided in this embodiment achieves precise expression and coordination of the building's complex geometry by establishing a three-dimensional model of the main steel structure and curtain wall system in the early stages of construction. First, the three-dimensional model, created through detailed design, accurately reproduces the geometric features of the hyperbolic irregular structure. Second, the three-dimensional modeling of the main steel structure and curtain wall system effectively improves the synergy between different systems, reduces on-site adjustments and errors, and makes processing and installation more efficient and precise. Due to the accuracy of the three-dimensional model, the entire construction process is better controlled, helping to reduce construction difficulty, improve project efficiency and construction precision, and ensure the aesthetics and structural stability of the hyperbolic irregular building. Furthermore, pre-assembling the curtain wall keel with the main steel structure allows for high-precision assembly on the ground, avoiding the complexity and safety risks of installing components one by one at height, significantly improving construction efficiency and installation precision, and greatly ensuring the accuracy of subsequent curtain wall panel installation.

[0065] In some embodiments, the curtain wall keel includes a main keel and a secondary keel.

[0066] For example, the main keel and the secondary keel can be made of aluminum or aluminum alloy.

[0067] Typically, the main steel structure serves as the primary load-bearing structure of a hyperbolic irregular building, connecting to the building's concrete structure. The main keel connects to the main steel structure, providing the main support for the external curtain wall panels. The secondary keel connects to the main keel, further refining the support for the curtain wall panels and ensuring their stability and precise positioning.

[0068] In step S1, based on the design drawings, three-dimensional models of the main steel structure and curtain wall system of the hyperbolic irregular building are established, specifically including:

[0069] The main steel structure is optimized into a straight line, the main keel is optimized into a single curve, and the secondary keel is optimized into a straight line. Based on the optimization results, a three-dimensional model of the main steel structure and the curtain wall keel is generated.

[0070] Specifically, based on the positional relationship between the finished surfaces of the curtain wall panels and the curtain wall keel in the design drawings, parametric data analysis can be used to optimize the main steel structure into a straight line to enhance its load-bearing capacity; the main keel can be designed as a single-curved shape to adapt to the building's shape requirements; and the secondary keels can be optimized into a straight shape for easier installation and connection. This optimization helps simplify the construction process, improves the operability and precision of construction, and ultimately generates a model containing all keel structures, thus providing accurate theoretical data support for actual construction and ensuring that each component can be accurately installed during actual construction.

[0071] like Figure 2As shown, in some embodiments, in step S2, the three-dimensional model of the main steel structure and the three-dimensional model of the curtain wall system are combined to form an overall model, including:

[0072] S21. After generating a three-dimensional model of the main steel structure and curtain wall keel based on the optimization results, determine the positioning points of the main steel structure, main keel and secondary keel through cross-sectional views at different elevation positions and verify them.

[0073] S22. Determine the relative positional relationship between the curtain wall system and the main steel structure based on the positioning points of the main steel structure, main keel and secondary keel;

[0074] S23. Identify potential collision points using collision detection tools, and adjust the 3D model of the main steel structure or the 3D model of the curtain wall system based on the collision detection results.

[0075] By accurately reflecting the connection and arrangement of each component at different heights through sectional views, positioning errors caused by spatial complexity can be effectively avoided. Furthermore, verifying the positioning points ensures that the position of each component corresponds precisely, thus providing an accurate basis for the coordination between models. After the positioning points are clear, establishing the precise relative positional relationship between the main steel structure and the curtain wall system ensures that each system can fit perfectly during mold assembly, avoiding model mismatch caused by positional errors. In addition, the application of collision detection tools can automatically identify potential conflict areas and make timely adjustments to potential collision points, ensuring the integrity of mold assembly and the smooth progress of subsequent installation.

[0076] For example, in the specific implementation of step S21, the main steel structure is first positioned. Three elevation positions are selected for the main steel structure, including elevation positioning point one, elevation positioning point two, and elevation positioning point three. The transverse sections of the main steel structure at different elevation positions are associated with the axis. The positioning of the main steel structure is performed using the transverse section diagrams of elevation positioning point one and elevation positioning point two, and verified using the transverse section diagram of elevation positioning point three. Next, the main keel is positioned using the coordinates of the starting point of the main keel and the coordinates of the first intersection point of the main keel and the main steel structure. The positioning is verified using the coordinates of the second intersection point of the main keel and the main steel structure. Finally, the secondary keel is positioned based on the coordinates of the secondary keel connection points on the main keel.

[0077] In some embodiments, step S3, which involves fabricating the main steel structure based on the overall model, includes:

[0078] The measurement points of each component in the main steel structure are determined according to the on-site construction sequence and actual on-site working conditions, and the measurement points are fed back to the overall model to convert the measurement points into processing coordinates.

[0079] The main steel structure is processed according to the processing coordinates;

[0080] After processing is completed, the processing coordinates of each component in the main steel structure are remeasured, and the remeasured data is fed back to the three-dimensional model of the main steel structure to calculate the deviation of the processing coordinates.

[0081] Determining the machining coordinates based on the 3D model accurately reflects the actual position and dimensional requirements of each component in the main steel structure in space, ensuring machining precision. After machining, each component is re-measured, and the re-measurement data is fed back to the 3D model. This allows for rapid verification of the matching degree between the machining results and the design model, timely detection of deviations or non-compliance, and prompt adjustments, further improving machining precision and quality control.

[0082] Furthermore, in some embodiments, the main steel structure is processed according to processing coordinates, and after processing is completed, the process further includes:

[0083] Three-dimensional scanning technology was used to measure each component in the main steel structure, and the measurement results were imported into the three-dimensional model of the main steel structure for mold assembly.

[0084] With this setup, 3D scanning technology can quickly and comprehensively acquire the actual geometric data of the main steel structure. Compared to traditional measurement methods, it offers higher accuracy and wider coverage, making it particularly suitable for complex hyperbolic irregular structures. Importing the measurement results into a 3D model for mold assembly allows for a direct comparison between the actual processing results and the design model, quickly identifying any potential deviations or non-compliance. This process ensures that the overall dimensions and shape of each component in the main steel structure are highly consistent with the design model, thereby reducing errors and adjustment needs in subsequent installation stages.

[0085] In some embodiments, step S3, which involves fabricating the curtain wall system based on the overall model, includes:

[0086] The three-dimensional model of the curtain wall keel in the curtain wall system is adjusted based on the actual measurement data of the main steel structure, and paperless drawing and material cutting are carried out based on the adjusted model.

[0087] The curtain wall keel is bent using a bending machine;

[0088] Use 1:1 keel bending drawings to verify the accuracy of the bent curtain wall keel. Specifically, the bent curtain wall keel and the keel bending drawings can be compared and verified 2 to 3 times to avoid the bending rebound affecting the accuracy.

[0089] By combining model adjustment, bending, and precision verification, the manufacturing accuracy and installation efficiency of the curtain wall system are improved, the amount of rework and adjustment work during construction is reduced, and the high consistency and aesthetics between the curtain wall system and the main structure are ensured.

[0090] like Figure 3 and Figure 4 As shown, the 1:1 keel bending drawing includes a keel bending error control line of 100 and a keel theoretical edge line of 200. For easy distinction, Figure 4 In the diagram, the keel bending error control line 100 is a solid line, and the keel theoretical edge line 200 is a dashed line. The keel theoretical edge line 200 represents the ideal curve shape the keel should achieve, while the keel bending error control line 100 sets an upper and lower limit for the theoretical edge line to ensure that the error during bending is controlled within an acceptable range. If the keel exceeds the range of the keel bending error control line 100, the bending needs to be readjusted until the keel shape meets the design requirements.

[0091] Furthermore, the 1:1 keel bending drawings can also include positioning point markings, such as the starting point marking of the main keel, the positioning point marking of the main keel support, and the positioning point marking of the secondary keel. During the bending process of the keel, these positioning point markings can be referenced to ensure that the shape of the bent keel matches the positioning points in the design model, thereby providing a precise benchmark for subsequent installation.

[0092] It should be noted that in some embodiments, the main keel in the curtain wall keel is bent, while in other embodiments, both the main and secondary keels in the curtain wall keel can be bent. The specific method depends on the actual situation.

[0093] Alternatively, the bending equipment can be a hydraulic bending machine, a CNC bending machine, etc., without specific limitations.

[0094] In some embodiments, in step S4, after the fabrication is completed, the curtain wall keel is first assembled to the main steel structure, and then hoisted as a whole after assembly, specifically including:

[0095] The connection structure of the main steel structure is 3D scanned and the 3D coordinates of the connection structure are determined. The 3D coordinates are then fed back to the overall model for comparison and adjustment.

[0096] The curtain wall keel is assembled into multiple first units, and these first units are then assembled with the main steel structure. The assembled curtain wall keel and main steel structure are then hoisted together as a whole.

[0097] In other words, after the fabrication is completed, the connection structure of the main steel structure is first subjected to precision control during on-site installation. This involves on-site measurement and scanning of the previous process before the main steel structure is installed. Through 3D scanning and model comparison, any deviations are adjusted promptly. If there are deviations that cannot be adjusted, the main steel structure must be adjusted to eliminate the error. Once the precision of the main steel structure meets the requirements, the curtain wall keel is then installed to the main steel structure. During installation, the curtain wall keel is assembled in a modular form using multiple first-unit modules. For example, the curtain wall keel can be shipped to the site in sections for assembly with the main steel structure. This modular assembly method improves construction efficiency and shortens the construction cycle.

[0098] Furthermore, in some embodiments, the curtain wall keel is assembled into multiple first units, and the multiple first units are assembled with the main steel structure. After the assembled curtain wall keel and main steel structure are hoisted as a whole, the process further includes:

[0099] The actual measurement points of the hoisted main steel structure and curtain wall keel were re-measured. At the same time, the hoisted main steel structure and curtain wall keel were 3D scanned, and the measurement results were imported into the 3D model of the main steel structure and the 3D model of the curtain wall system for model merging.

[0100] This setup allows for the timely detection of deviations during installation, ensuring that the positioning and shape of each component remain consistent with the design model, avoiding subsequent adjustments and rework, and significantly improving installation accuracy and construction efficiency.

[0101] In actual construction, due to the large size of the building, the main steel structure can usually be divided into multiple segments. The first unit of the curtain wall keel is assembled onto the corresponding segment, and then the assembled segment and the first unit are hoisted together in sequence. Before the installation of each segment, any errors that cannot be eliminated on-site in the previous segment need to be reported to the processing plant for component adjustment. After adjustment, the installation work of subsequent segments continues with the installation process of the previously installed segment in mind.

[0102] like Figure 5 As shown, in some embodiments, the main steel structure is connected to the building's concrete structure 400 via connectors 300.

[0103] Preferably, the connector 300 is inclined relative to the concrete structure 400, and the connection with the concrete structure 400 can move up and down to absorb the stress generated by the main steel structure.

[0104] In some embodiments, the installation of the curtain wall panel to the curtain wall keel in step S4 specifically includes:

[0105] The curtain wall panels are assembled into multiple second units, which are then sequentially installed onto the curtain wall frame. Specifically, the second units can be installed layer by layer from top to bottom using scaffolding.

[0106] This setup allows the curtain wall panels to be pre-assembled into modular second units, enabling standardized assembly and debugging on the ground. This ensures tight connections between panels that meet design requirements, avoids the accumulation of errors and on-site adjustments associated with piece-by-piece installation, further optimizes the construction process, and improves overall installation efficiency and precision.

[0107] Optionally, the curtain wall panels can be made of aluminum. Of course, in other embodiments, the curtain wall panels can also be made of other materials, such as stainless steel or glass, depending on the actual situation.

[0108] In some embodiments, the curtain wall panel can be configured as a two-layer structure. For example, the outer layer can be an aluminum panel for external protection and decoration, while the inner layer can be an aluminum plate or other materials, serving to increase structural stability, provide waterproofing and thermal insulation, etc. This two-layer design helps improve the overall performance of the curtain wall panel.

[0109] Specifically, the inner structure can be a 1.2mm thick waterproof aluminum plate, which is installed on the curtain wall keel. The outer structure can be a 4mm thick aluminum plate, which can be installed on the inner waterproof aluminum plate using T-shaped aluminum alloy adapters, aluminum round tubes, aluminum alloy clamps, etc. The specific installation steps are mature existing technologies in this field and will not be described in detail here.

[0110] In some embodiments, after the curtain wall system is installed, it further includes:

[0111] A 3D scan of the facade of the curtain wall system is performed, and the scanned data is fed back to the original overall model for comparison. Adjustments or repairs are then made based on the comparison results.

[0112] With this setup, 3D scanning technology can comprehensively acquire the actual geometric data of the curtain wall system's facade, such as its actual shape and dimensions, and compare it with the design model to promptly identify areas with significant deviations. Furthermore, combined with a real-time feedback and adjustment mechanism, this not only improves the accuracy and quality after construction but also provides reliable data support for subsequent maintenance and management, ensuring the building's long-term durability and optimized functionality.

[0113] Alternatively, 3D scanning can be performed using a high-precision 3D laser scanner.

[0114] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
