Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a construction method for irregularly shaped twisted aluminum panel cladding. Background Technology

[0002] With the rapid development of my country's economy and society, buildings with complex appearances and increasingly diverse forms are emerging. Correspondingly, curtain wall cladding systems are increasingly exhibiting multi-dimensional and irregular spatial characteristics, especially with the growing application of complex streamlined, freely twisted aluminum panel curtain wall cladding, which exhibits large curvature variations without a clear pattern. To accurately reproduce the design of complex architectural forms, it is essential to ensure the uniformity and smoothness of the joints between the cladding panels. Therefore, this places extremely high demands on the precision of the cladding construction for beams and columns in irregular spatial structures.

[0003] In existing technologies, the construction of irregularly shaped twisted aluminum panel cladding is not conducive to handling errors and deviations in the aluminum panels, and cannot guarantee a natural transition and uniform joints in the aluminum panel cladding. This results in unevenness, abrupt changes in shape, transitional breaks, and incompleteness at the panel joints. To address these issues, we propose a construction method for irregularly shaped twisted aluminum panel cladding. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies in the construction of irregularly shaped twisted aluminum panel cladding, which make it difficult to handle errors and deviations in the aluminum panels, and cannot guarantee a natural transition and uniform joints in the aluminum panel cladding. This results in unevenness, abrupt changes in shape, transitional breaks, and incompleteness at the panel joints. Therefore, this invention proposes a construction method for irregularly shaped twisted aluminum panel cladding.

[0005] The construction method for irregularly shaped twisted aluminum panel cladding provided in this application adopts the following technical solution: A method for constructing irregularly shaped twisted aluminum panel cladding includes the following steps: S1: For decorative aluminum panels with small twist, after high-precision 3D scanning at the processing plant to meet the error requirements, they are directly sent to the site. On the site, the keel and aluminum panels are first assembled into modules using construction equipment, and then hoisted into place. The construction equipment includes a base, and a positioning mechanism is set on the top of the base. The positioning mechanism includes a connecting plate, which is fixedly installed on the top of the base. A support seat is connected to the top of the connecting plate, and a column is fixedly installed on the top of the support seat. A first sliding groove is opened on the top of the column, and a sliding plate is slidably installed in the first sliding groove. A clamping mechanism is set on the sliding plate to clamp the irregularly shaped twisted aluminum panels. S2: For decorative aluminum panels with large twist and complex irregular node areas, the keel and aluminum panels are first modularly assembled in the processing plant. After the keel and aluminum panels are assembled, a 3D scanner is used twice for high-precision scanning. The point cloud model formed by the scanning is reverse-engineered into a solid model and compared and corrected with the fitted and adjusted design BIM model. Finally, it is transported to the site and hoisted into place. This avoids the situation where large twist aluminum panels are repeatedly returned to the factory for repair due to the installation accuracy and effect not meeting the requirements. By using the above method, a large number of small component materials are spliced ​​into unit modules, which not only ensures the accurate positioning of material installation but also reduces safety and quality risks during the installation process. It also ensures the same degree of twisting of the keel and aluminum plate and the overall forming effect. S3: Due to the large twist of the aluminum panels in complex node areas, the processing error is larger than that of other aluminum panels. In addition, there are many aluminum panels in the corresponding areas. When many aluminum panels are assembled together, an "error amplification" effect will be formed, resulting in a large cumulative error. As a result, it is impossible to form a smooth transition surface with aluminum panels in other areas. The installation of aluminum panels in complex node areas is crucial to the overall aluminum panel cladding effect. Therefore, in terms of the overall construction sequence, the construction of large-volume complex free-twisting aluminum panel cladding is divided into two stages: Stage 1, design, processing and installation of aluminum panels in complex node areas; Stage 2, secondary refinement, processing and installation of aluminum panels in the remaining areas. S4: After the aluminum panels in the complex node area are assembled into modular units at the processing plant, they are hoisted into the site. After the node area is positioned and installed, a 3D scanner is used to scan the aluminum panel surface. The surface solid model formed by reverse modeling is compared and corrected with the design surface BIM model. After correction, a "corrected model" consistent with the actual site is formed. This model replaces the original design model and the surface is "secondary detailed design and optimization". S5: It is difficult to achieve complete consistency between on-site installation and the original design theoretical model. It is also uneconomical to consume a lot of manpower and time. The best overall benefit is to achieve the aluminum panel veneer forming effect within an acceptable error range. Therefore, the purpose of the secondary detailed design is to make appropriate adjustments and optimizations to the aluminum panel skin in other remaining areas, quickly identify and compensate for the errors generated in the complex node areas of the first stage, so as to ensure smooth transition of the lines and uniform joints of the overall veneer. In order to achieve rapid detailed design, a free surface optimization algorithm program group is developed based on Rhino and the parametric plugin Grasshopper to automatically determine the optimal error compensation plate, point and value, and realize intelligent construction. S6: After the second refinement is completed, the design model is submitted to the processing plant for intelligent processing, thereby avoiding the problem of the aluminum plate not being able to be spliced ​​smoothly on site due to the early processing of aluminum plates. Since the aluminum plate has a small degree of twist in non-complex node areas, the accuracy is easier to control in the processing and installation process, and there is no need to conduct further refinement design, thus reducing the impact on the construction progress. S7: Reserve a section on the straight section of each beam wrapping segment as a finishing edge to absorb and compensate for the cumulative errors during construction and control the slab joints. After the construction of each individual venue is completed, start sorting out the finishing edge work. Reserve the last section at the bottom of each column wrapping segment as a finishing edge to compensate for the construction errors of the garden ground. After the large-area construction of the column wrapping segment of each individual venue is completed, sort out the finishing edge position and place the order with a reverse ruler. S8: For aluminum plates with small twist, in order to avoid situations such as improper installation or even inability to install due to aluminum plate size errors or springback deformation, a simple cold bending device can be used to cold bend the aluminum plate directly on the construction site, without the need to return it to the factory for correction, thus avoiding waste and affecting the construction period. S9: In the aluminum panel installation and positioning stage, a "high-precision tracking and monitoring method combining multi-stage point cloud data of the curtain wall with a measurement robot" is adopted. By jointly adjusting and fusing point cloud data and measurement robot data, high-precision multi-stage deformation data and point cloud data are obtained. Real-time tracking and monitoring of aluminum panel installation positioning, deformation of key parts, and surface transition points are carried out to detect abnormalities in the aluminum panel installation process in real time and take timely adjustment measures, which greatly improves the controllability of the implementation.

[0011] Furthermore, in S1, a third through hole is provided on the bottom inner wall of the first through groove. The third through hole communicates with the second sliding groove. A rectangular rod is rotatably installed in the third through hole. The rectangular rod is slidably installed in two rectangular holes.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution uses modular assembly on-site and in the factory, combined with 3D scanning reverse modeling technology and an error compensation mechanism to ensure that the irregularly shaped twisted aluminum panels have uniform seams and smooth lines after installation. This effectively avoids problems such as unevenness and abrupt changes in shape at the joints of the panels, and highly restores the complex curved surface effect of the architectural design. 2. This solution adopts a "two-stage installation method" and error compensation design. First, aluminum plates in complex node areas are installed and the model is corrected. Then, the remaining aluminum plates are further refined. This avoids repeated returns to the factory for repair due to accumulated errors, significantly improves construction efficiency, and shortens the construction period. 3. This solution combines 3D scanning, Rhino+Grasshopper parametric optimization algorithm, and real-time monitoring by a measurement robot to achieve intelligent error identification, compensation, and high-precision tracking during the aluminum plate installation process, thereby improving the controllability of construction quality and reducing human intervention errors and safety risks.

[0015] This invention addresses the errors and deviations in aluminum panels, ensuring a natural transition and uniform seams in the aluminum panel finish. It avoids unevenness, abrupt changes in shape, discontinuous transitions, and incompleteness at panel joints, thus efficiently reproducing the architectural design effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 Reference Figures 1-8 A method for constructing irregularly shaped twisted aluminum panel cladding includes the following steps: S1: For decorative aluminum panels with small twist, after high-precision 3D scanning at the processing plant to meet the error requirements, they are directly sent to the site. On the site, the keel and aluminum panels are first assembled into modules using construction equipment, and then hoisted into place. The construction equipment includes a base 1, and a positioning mechanism is set on the top of the base 1. The positioning mechanism includes a connecting plate 2, which is fixedly installed on the top of the base 1. A support base 3 is connected to the top of the connecting plate 2, and a column 4 is fixedly installed on the top of the support base 3. A first sliding groove 11 is opened on the top of the column 4, and a sliding plate 5 is slidably installed in the first sliding groove 11. A clamping mechanism is set on the sliding plate 5, which is used to clamp the irregular twisted aluminum panels. The implementation principle of the construction device is as follows: the base 1 is fixed in the construction area, and the electromagnet 10 at the bottom of the support base 3 is energized and attracted to the top of the connecting plate 2 to achieve stable fixation of the device. The position can be flexibly adjusted according to the shape of the aluminum plate. The number of positioning mechanisms is set according to the actual construction situation. Start cylinder 12 to push slide plate 5 vertically up and down along the first slide groove 11 of support column 4, and adjust it to the height required for aluminum plate assembly; Turn on the drive motor 6 to drive the bidirectional lead screw 19 to rotate, which in turn drives the two clamping plates 7 to move towards each other along the second slide groove 13, initially clamping the edge of the aluminum plate. The bidirectional lead screw 19 synchronously drives the first gear 20 to rotate, and drives the rectangular rod 22 to rotate through the meshing second gear 21. The rectangular rod 22 drives the two rotating shafts 23 to rotate synchronously through the rectangular hole 24. The rotating shafts 23 are converted into the rotational motion of the screw 27 through the meshing of the first bevel gear 25 and the second bevel gear 26. The screw 27 pushes the piston plate 18 to move linearly in the cavity 16 and inflates the airbag 8 through the inflation hole 17. After inflation, the airbag 8 adapts to the curved shape of the irregular aluminum plate to form a flexible support. Through the combined action of rigid clamping and flexible support, the precise positioning and non-destructive fixing of the twisted aluminum plate are achieved during the assembly process. S2: For decorative aluminum panels with large twist and complex irregular node areas, the keel and aluminum panels are first modularly assembled in the processing plant. After the keel and aluminum panels are assembled, a 3D scanner is used twice for high-precision scanning. The point cloud model formed by the scanning is reverse-engineered into a solid model and compared and corrected with the fitted and adjusted design BIM model. Finally, it is transported to the site and hoisted into place. This avoids the situation where large twist aluminum panels are repeatedly returned to the factory for repair due to the installation accuracy and effect not meeting the requirements. By using the above method, a large number of small component materials are spliced ​​into unit modules, which not only ensures the accurate positioning of material installation but also reduces safety and quality risks during the installation process. It also ensures the same degree of twisting of the keel and aluminum plate and the overall forming effect. S3: Due to the large twist of the aluminum panels in complex node areas, the processing error is larger than that of other aluminum panels. In addition, there are many aluminum panels in the corresponding areas. When many aluminum panels are assembled together, an "error amplification" effect will be formed, resulting in a large cumulative error. As a result, it is impossible to form a smooth transition surface with aluminum panels in other areas. The installation of aluminum panels in complex node areas is crucial to the overall aluminum panel cladding effect. Therefore, in terms of the overall construction sequence, the construction of large-volume complex free-twisting aluminum panel cladding is divided into two stages: Stage 1, design, processing and installation of aluminum panels in complex node areas; Stage 2, secondary refinement, processing and installation of aluminum panels in the remaining areas. S4: After the aluminum panels in the complex node area are assembled into modular units at the processing plant, they are hoisted into the site. After the node area is positioned and installed, a 3D scanner is used to scan the aluminum panel surface. The surface solid model formed by reverse modeling is compared and corrected with the design surface BIM model. After correction, a "corrected model" consistent with the actual site is formed. This model replaces the original design model and the surface is "secondary detailed design and optimization". S5: It is difficult to achieve complete consistency between on-site installation and the original design theoretical model. It is also uneconomical to consume a lot of manpower and time. The best overall benefit is to achieve the aluminum panel veneer forming effect within an acceptable error range. Therefore, the purpose of the secondary detailed design is to make appropriate adjustments and optimizations to the aluminum panel skin in other remaining areas, quickly identify and compensate for the errors generated in the complex node areas of the first stage, so as to ensure smooth transition of the lines and uniform joints of the overall veneer. In order to achieve rapid detailed design, a free surface optimization algorithm program group is developed based on Rhino and the parametric plugin Grasshopper to automatically determine the optimal error compensation plate, point and value, and realize intelligent construction. S6: After the second refinement is completed, the design model is submitted to the processing plant for intelligent processing, thereby avoiding the problem of the aluminum plate not being able to be spliced ​​smoothly on site due to the early processing of aluminum plates. Since the aluminum plate has a small degree of twist in non-complex node areas, the accuracy is easier to control in the processing and installation process, and there is no need to conduct further refinement design, thus reducing the impact on the construction progress. S7: Reserve a section on the straight section of each beam wrapping segment as a finishing edge to absorb and compensate for the cumulative errors during construction and control the slab joints. After the construction of each individual venue is completed, start sorting out the finishing edge work. Reserve the last section at the bottom of each column wrapping segment as a finishing edge to compensate for the construction errors of the garden ground. After the large-area construction of the column wrapping segment of each individual venue is completed, sort out the finishing edge position and place the order with a reverse ruler. S8: For aluminum plates with small twist, in order to avoid situations such as improper installation or even inability to install due to aluminum plate size errors or springback deformation, a simple cold bending device can be used to cold bend the aluminum plate directly on the construction site, without the need to return it to the factory for correction, thus avoiding waste and affecting the construction period. S9: In the aluminum panel installation and positioning stage, a "high-precision tracking and monitoring method combining multi-stage point cloud data of the curtain wall with a measurement robot" is adopted. By jointly adjusting and fusing point cloud data and measurement robot data, high-precision multi-stage deformation data and point cloud data are obtained. Real-time tracking and monitoring of aluminum panel installation positioning, deformation of key parts, and surface transition points are carried out to detect abnormalities in the aluminum panel installation process in real time and take timely adjustment measures, which greatly improves the controllability of the implementation.
