[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1 This invention provides a method for constructing large-scale, irregularly shaped, inclined honeycomb aluminum panels for curtain walls. By setting different inward tilt angles of the curtain wall and varying the combined area of ​​the glass and honeycomb aluminum panels at different angles and heights, a transparent and ethereal design is achieved, creating a decorative shape that appears both man-made and naturally formed. The method for constructing large-scale, irregularly shaped, inclined honeycomb aluminum panels for curtain walls according to this invention will be described below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0032] See Figure 1 This image shows a three-dimensional model of the large-scale, irregularly shaped, inclined honeycomb aluminum panel for the curtain wall of this invention. The following is in conjunction with... Figure 1 The present invention describes the construction method of large-scale irregular inclined curtain wall honeycomb aluminum panels.

[0033] like Figure 1 As shown, the construction method of large-scale irregular inclined curtain wall honeycomb aluminum panels of the present invention firstly adopts three-dimensional digital model design to establish a three-dimensional digital model of the curtain wall according to the shape requirements of the irregular curtain wall.

[0034] Specifically, parametric modeling is performed using BIM software, specifically Rhino+Grasshopper, and the battery pack model is quickly displayed in the Rhino interface, enabling visual programming operations.

[0035] In the 3D digital modeling process, the vertical keel, horizontal keel, inner honeycomb aluminum panel, and outer honeycomb aluminum panel are meticulously modeled. This model serves as the basis for construction drawings, clearly defining the arrangement sequence of each aluminum panel, the rules for the vertical and horizontal keel layout, and their spatial positions, guiding on-site construction. Parametric modeling using Rhino+Grasshopper allows for rapid model display within the Rhino interface with only a few battery packs, enabling visual programming operations. This solves the problem of large modeling workload due to varying sizes of the partition glass panels. It also enables rapid modeling and numbering of irregularly shaped columns, providing accurate data for honeycomb panel fabrication.

[0036] The parametric modeling process for curtain walls includes: First, using parametric programming to extract the required profiles for the panels, facilitating the batch generation of the necessary aluminum alloy profiles later; second, using parametric programming to integrate the optimized curtain wall grids and extract the complete curtain wall panels; third, using parametric programming to analyze the data, points, grids, and positioning of the re-optimized and integrated complete panel panels; and fourth, using parametric programming to generate the corresponding aluminum alloy keel based on the above data analysis. Parametric programming allows for the rapid creation of curtain wall grid units with varying inclination angles and glass and honeycomb aluminum panel combination areas at different angles and heights by changing parameters.

[0037] By creating a three-dimensional digital model of the curtain wall, it is easy to calculate the materials required for construction. Before the project begins, the vertical keel and aluminum panels of the curtain wall can be measured, and the quantity of materials can be accurately calculated.

[0038] like Figure 7 The diagram shows a schematic of the inner honeycomb aluminum panel. This inner honeycomb aluminum panel is generally U-shaped, with the opening width greater than the width of the closed end. The structural design of this inner honeycomb aluminum panel was achieved using a three-dimensional digital model. Two horizontal ribs 231 and two vertical ribs 232 are provided on the inner surface of the inner honeycomb aluminum panel 23. The horizontal ribs 231 are spaced apart along the length of the inner honeycomb aluminum panel 23, while the vertical ribs 232 are located on the inner surface of the closed end and run continuously along the length of the inner honeycomb aluminum panel 23. The arrangement of the horizontal and vertical ribs makes the stress distribution of the inner honeycomb aluminum panel more reasonable. The structure of the outer honeycomb aluminum panel is the same as that of the inner honeycomb aluminum panel.

[0039] During the 3D digital modeling process, detailed models of honeycomb aluminum panels, aluminum grilles, and glass are created, and construction drawings are drawn based on these models. The arrangement sequence of each aluminum panel, the layout rules of the honeycomb aluminum panels, and the spatial position of the ultra-clear glass are clearly defined to guide on-site construction.

[0040] Utilizing BIM to refine order placement and on-site installation of honeycomb aluminum panels: Based on the curtain wall type and complexity, BIM modeling is initiated. According to the curtain wall structure and construction sequence, BIM models are created at different levels, including the keel, sub-frame, and panel material. Order dimensions and connection nodes are verified against the BIM model, and clashes are checked. Figure 8 As shown.

[0041] With the assistance of BIM, the vertical keel is refined for order placement and on-site installation, and key details are further refined to ensure the reliability of the nodes and the convenience of installation.

[0042] In one specific embodiment of the present invention, the construction method of large-scale irregularly shaped inclined curtain wall honeycomb aluminum panels of the present invention includes the following steps: like Figure 12 As shown, a vertical keel 21 is provided, and the vertical keel 21 is installed on the outside of the main structure according to the layout plan. The vertical keel 21 is set at an angle. Provide connecting ear plates 211, install the provided connecting ear plates 211 on opposite sides of the vertical keel 21, and set the connecting ear plates 211 close to the indoor side of the vertical keel 21; like Figure 13 As shown, a connector 22 is provided, which is disposed on both sides of the vertical keel 21 and fixedly connected to the corresponding connecting ear plate 211; like Figure 14 As shown, an inner honeycomb aluminum panel 23 is provided, which is then fastened to the indoor side of the vertical keel 21, and the inner honeycomb aluminum panel 23 is fixedly connected to the corresponding connector 22 through the first clip. like Figure 15 As shown, a glass plate 24 is provided, which is connected to the corresponding connector 22 by fastener 241, and the glass plate 24 is placed on both sides of the vertical keel 21. like Figure 16 As shown, an outer honeycomb aluminum panel 25 is provided, which is then fastened to the outdoor side of the vertical keel 21, and the outer honeycomb aluminum panel 25 is fixedly connected to the vertical keel 21 by a second fastener 251. A decorative cover is provided and placed between the end of the outer honeycomb aluminum plate 25 and the corresponding glass plate 24.

[0043] Combination Figure 2 and Figure 11As shown, glass panels 24 are installed on both sides of the vertical keel 21. The inner honeycomb aluminum panel 23 and the outer honeycomb aluminum panel 24 are covered on the indoor and outdoor sides of the two vertical keels 21, covering the connection between the glass panel 24 and the vertical keel 21. The color of the outer honeycomb aluminum panel 24 can be designed according to the needs of the shape. The top of the vertical keel 21 is inclined towards the indoor side, and the combined area of ​​the glass panel 24, the inner honeycomb aluminum panel 23 and the outer honeycomb aluminum panel 25 varies in different positions, thus forming the required curtain wall shape.

[0044] Furthermore, such as Figure 5 and Figure 6 As shown, when installing the vertical keel 21, an embedded part 214 is set in the ground to connect and fix the bottom of the vertical keel 21 to the embedded part 214; A connecting plate 215 is installed at the top of the main structure to connect and fix the top of the vertical keel 21 to the connecting plate 215.

[0045] Specifically, a connecting seat 216 can be provided on the inner side of the vertical keel 21 near the top, and the connecting seat 216 and the connecting plate 215 can be connected and fixed by bolts or other fasteners. An opening is provided on the inner side of the inner honeycomb aluminum plate 23 corresponding to the connecting seat 216 so that the connecting seat 216 can extend out from the opening.

[0046] The embedded part 214 is preferably a connecting lug, and a connecting lug plate is provided at the bottom of the vertical keel 21. The lug plate is connected and fixed to the connecting lug by bolts.

[0047] Furthermore, before installing the vertical keel 21, the structure is measured and positioned to measure the structural deviations in preparation for construction. After measurement, the installation reference line needs to be determined, including the vertical keel layout reference and the horizontal elevation line of each part of the curtain wall, to determine the reference in three directions for each different part of the curtain wall.

[0048] Doorways are provided on each side of the curtain wall, with steel frames installed at each doorway. These frames are formed by connecting steel square tubes, which are welded to pre-placed embedded parts. The upper frame uses 500*400*20 and 300*200*12 steel square tubes, with 150*150*8 steel square tubes embedded within. The 500*400*20 steel square tubes are connected to the vertical keel (using steel columns) of the curtain wall facade. This area extensively uses non-standard, extra-large, and extra-thick steel as the main keel for the steel doorway frames, primarily made of Q355B steel. Steel thickness ≥18mm uses a ∠-shaped bevel, with a weld leg size of 1 / 2 plate thickness. Additional reinforcement is achieved using foot welds, forming an effective weld throat. The weld leg must be well-formed, with minimal deformation, smooth transition, and reasonable design, while also meeting design requirements. Based on the on-site welding conditions, two welding methods were selected: manual arc welding with electrode welding and gas shielded welding. The welding equipment selected included a manual arc welding machine and a gas shielded welding machine.

[0049] like Figure 4 As shown, the vertical keel 21 is inclined inward at the top. When installing the vertical keel 21, it is necessary to ensure the installation accuracy of the vertical keel 21, combined with... Figure 9 and Figure 10 As shown, when installing the vertical keel 21, a positioning ruler is used to assist in the installation of the vertical keel 21. When installing the vertical keel 21, the previously installed vertical keel is used as a reference, and the positioning ruler is used to position the next vertical keel to be installed. After positioning, the next vertical keel to be installed is installed and fixed.

[0050] The positioning scale is set at 1 / 3 of the height of the vertical keel to be positioned from the top, so as to calibrate and adjust the vertical keel.

[0051] The positioning scale includes a crossbar 31 and a first bracket 32 ​​and a second bracket 33 located at both ends of the crossbar 31. The first bracket 32 ​​and the second bracket 33 are cut and bent from 3mm thick galvanized steel plates. The clamping width of the first bracket 32 ​​and the second bracket 33 is 1mm wider than the width of the vertical keel 21 to facilitate the movement and adjustment of the first bracket 32 ​​and the second bracket 33 relative to the vertical keel 21. A mechanism for measuring the tilt angle is fixed on the first bracket 32 ​​and the second bracket 33, including a protractor installed in the middle of the first bracket 32 ​​and the second bracket 33. The horizontal line of the protractor coincides with the horizontal line of the corresponding first bracket 32 ​​and the second bracket 33. A fixed shaft is riveted at the center of the protractor, and a steel stick is installed. Under the action of gravity, the steel stick points vertically downward. The length of the crossbar 31 is customized according to the distance between the vertical keels. A level adjuster is provided on the crossbar 31, and the level is adjusted by the liquid column of small air bubbles in the glass tube.

[0052] Position the fixed reference column (vertical keel) using a total station and designate it as column A. Designate the adjacent column (vertical keel) to be constructed as column B. After column B is lifted into place, it is temporarily fixed at the top and bottom. The hoisting machinery is not unloaded. Then, a ruler is used to assist in positioning. (1) According to the specifications and spacing of the columns on the drawings, select the corresponding brackets and crossbars to form a ruler. First, attach the brackets on column A to fix it. Then, adjust the ruler and observe the level adjuster to make the crossbar reach a horizontal state. Then, slowly attach column B to the brackets on the other side of the ruler. (2) Read the tilt angle data of the two tilt angle measuring mechanisms and adjust the tilt angle of column B until the readings on both sides are the same and meet the angle requirements of the drawings. Check whether the crossbar is still horizontal. After repeating twice without error, fix column B. Finally, unload the hoisting machinery and disassemble the ruler.

[0053] In one specific embodiment of the present invention, such as Figure 11 , Figures 18 to 22As shown, after the vertical keel 21 is installed, a horizontal keel 26 and a subframe 27 are provided. The provided horizontal keel 26 and subframe 27 are positioned and installed on the vertical keel 21 according to the installation position.

[0054] Positioning: Accurately position the beams and subframes according to the drawings and the measurement and layout control points.

[0055] Installation: The subframe must be assembled on the ground first. Then, use mechanical equipment to hoist the beam and subframe to the installation position. Angle iron or other materials can be used as support plates in advance to assist in the installation. After adjusting the position, weld the beam and subframe to the column.

[0056] Inspection: After the crossbeams are installed, they should be inspected, mainly checking the following: whether the various crossbeams are correctly positioned, whether the crossbeams and columns fit together, and whether the crossbeams are level.

[0057] Furthermore, when installing the inner honeycomb aluminum panel, a lifting frame is provided to attach the lifting frame to the outside of the inner honeycomb aluminum panel; The inner honeycomb aluminum panel is lifted to the installation position using a hoisting frame. A traction rope is installed on the hoisting frame, and the traction rope is used to control the installation of the inner honeycomb aluminum panel into place.

[0058] Furthermore, when installing the inner honeycomb aluminum panel, a shim is placed between the bottom of the inner honeycomb aluminum panel and the corresponding horizontal keel to support the inner honeycomb aluminum panel.

[0059] Positioning: Before installation, laser positioning is used to mark the steel frame to determine the installation position of the steel support, and the honeycomb aluminum panel connectors are checked to ensure that they match the position of the steel support installed on site.

[0060] The aluminum profile hangers on the honeycomb aluminum panel are pre-installed and adjusted to the theoretical installation size, but not tightened in preparation for on-site three-dimensional adjustments.

[0061] Lifting: Due to the large length of the honeycomb aluminum panels, conventional lifting lugs can easily damage the embedded sleeves, leading to safety accidents. A specially designed lifting steel frame must be attached to the outside of the honeycomb aluminum panels. The steel frame bears the lifting load and protects the panels. During lifting, edge protection must be ensured to prevent rigid contact between the steel frame and the outer surface of the honeycomb aluminum panels, which could damage the panel surface. A traction rope should be attached to the lifting steel frame to guide the honeycomb aluminum panels into position and prevent collisions with the steel structure during installation. Before lifting, a pre-lift should be performed to check the balance of the lifting points and the panels. Lifting should be done using a combination of large and small hooks with a chain guide (the chain guide should be placed at the highest point of the panel). The panel should be lifted and moved only after it has reached an upright position in the air. When the panel is lifted to the installation position, it should be lowered slowly and controlled with traction ropes to ensure no collisions during the lifting process.

[0062] After the honeycomb aluminum panel is hoisted to the installation position, use the auxiliary guide chain of the hook at the highest point for fine-tuning the vertical movement. Use the guide chain at the bottom of the panel for angle adjustment. During the guide chain adjustment, constantly monitor the panel's position to prevent damage due to the keel's limiting mechanism. After adjusting the installation position, insert nylon shims between the honeycomb aluminum panel and the lower crossbeam to adjust the height and support the weight of the honeycomb aluminum panel. Then, use M8*40 stainless steel machine screws for pre-connection but not tightening, and then remove the hoisting steel frame. After adjusting the honeycomb aluminum panel to the marked position, tighten the screws. This process can be done by adjusting the position of the honeycomb aluminum panel using toothed connectors to ensure the straightness of the upper and lower layers of honeycomb aluminum panels.

[0063] Inspection: After the honeycomb aluminum panels are installed, it is necessary to check whether the number, location and tightness of the fixing points meet the design requirements, whether there is any installation damage, and the straightness of the surface, etc.

[0064] In one specific embodiment of the present invention, when installing the glass plate, a rubber strip is provided on the side of the connector close to the glass plate, and the rubber strip is used to adhere to the inner side of the installed glass plate.

[0065] Before installation, laser positioning is used to mark the glass installation position on the steel frame. During handling and hoisting, vacuum suction cups should be used for multi-point hoisting, and edge protection should be provided to prevent bumps and scratches. When fixing the glass sub-frame, toothed connectors are used for adjustment to ensure the flatness of the glass, the size of the dividing joints, and other specifications. The quality of sealant application must be ensured; the substrate surface should be cleaned before applying the sealant to ensure reliable adhesion. The sealant should be applied continuously and fully at the intersections of horizontal and vertical joints and in concealed areas, without bubbles, cracks, or other defects.

[0066] Installation of the outer honeycomb aluminum panel: Positioning: Before installation, laser positioning is used to mark the steel frame to determine the installation position of the steel support, and the honeycomb aluminum panel connectors are checked to ensure that they match the position of the steel support installed on site.

[0067] The aluminum profile hangers on the honeycomb aluminum panel are pre-installed and adjusted to the theoretical installation size, but not tightened in preparation for on-site three-dimensional adjustments.

[0068] Outdoor sunshade aluminum panel installation: Installation: The sunshade aluminum panel is fixed to the aluminum panel keel with self-tapping and self-rotating screws to ensure the flatness of the sunshade aluminum panel, the size of the sealant joint, and other indicators.

[0069] Inspection: After installation, check in a timely manner whether the positioning is accurate and whether the installation surface is level. If the error is too large, adjust it in time.

[0070] like Figure 8 and Figure 6As shown, the sunshade aluminum plate 28 is installed on the top of the vertical keel 21, at the top edge of the main structure, and the top of the vertical keel 21 is covered by the sunshade aluminum plate 28.

[0071] like Figure 3 and Figure 4 As shown, the installed vertical keel 21 is set at an angle with the bottom closer to the outside of the main structure than the top.

[0072] The upper part of the vertical keel 21 is provided with a bracket 213 and a connecting column 212. The connecting column 212 is connected to one side of the vertical keel 21 through the bracket 213 to increase the cross-sectional size of the corresponding part of the vertical keel 21 so as to match the inner honeycomb aluminum plate and the outer honeycomb aluminum plate of the corresponding shape.

[0073] like Figure 17 As shown, before installing the decorative cover, a drainage channel 29 is provided, and the drainage channel 29 is installed between the end of the outer honeycomb aluminum panel 25 and the corresponding glass panel 24. The decorative cover plate is placed on the outside of the drain trough 29.

[0074] The cross-section of the drainage channel 29 is [shaped], with the opening facing outwards.

[0075] Furthermore, it also includes: A three-dimensional digital model of the curtain wall is created based on the required curtain wall design. Based on the established three-dimensional digital model, construction drawings are drawn to determine the layout scheme of the vertical keel and the arrangement sequence of the inner and outer honeycomb aluminum panels, and the construction of the curtain wall honeycomb aluminum panels is carried out accordingly.

[0076] like Figures 18 to 22 As shown, before installing the outer honeycomb aluminum panel, the horizontal keel 26 is first installed on the indoor side, and then the subframe 27 is installed on the horizontal keel 26. Then, the glass rib 242 is installed on the outdoor side, and the upper and lower glass panels 24 are connected by the glass rib 242. After the glass panel 24 is installed, the outer honeycomb aluminum panel 25, the horizontal keel 26 and the subframe 27 are installed.

[0077] The steel processing for the irregularly shaped inclined curtain wall of this invention varies (16 types), with no two cross-sections alike, resulting in complex data. The panel materials also vary in size, quantity, and specifications, making processing difficult. This invention employs parametric processing, using BIM software to extract all data such as steel cross-section, length, and quantity. Material orders and processing are numbered and matched one-to-one, and materials arrive on-site according to the construction plan requirements.

[0078] During the construction of the facade steel frame columns of this invention, after the columns are hoisted to the designated position, traditional methods, besides total station measurement for positioning, cannot provide rapid measurement and are constrained by site conditions while lacking quick verification methods. The positioning of the embedded steel plates can be verified by using spatial straight-line distance to check their accuracy. By calculating the spatial relationship of the embedded steel plate endpoints using BIM software, site managers can quickly verify the length of the embedded steel plate connectors, thereby improving construction efficiency.

[0079] The processing and installation of the steel columns (vertical keel) of this invention is of paramount importance to the visual effect of this project. The precision of hole machining and the control of welding deformation are extremely demanding conditions in curtain wall construction. Considering the length limitations of the steel columns (20m-42m), the project team adopted a two-stage splicing process: workshop and on-site. In addition to merging multiple lengths on-site to accelerate splicing, the factory production workshop used a BIM model to simulate on-site conditions at a one-to-one scale. Calculations using BIM software determined the spatial relationship between panels and holes. When splicing two semi-finished steel columns, heating and dehumidification treatment should be carried out, the weld joint should be cleaned before welding, and attention should be paid to welding current adjustment and gas testing. The steel column material is Q355B, requiring the use of appropriate welding rods (E50 type welding rods). A multi-segment symmetrical welding method was adopted to avoid welding deformation, ensuring continuous welds and no welding quality issues.

[0080] The facade of this invention features an inward-sloping design, making hoisting a key challenge. Based on the actual site conditions, a boom lift (36-41m) was used in conjunction with a crane for the installation of the honeycomb aluminum panel curtain wall system. At doorways, a scissor lift (6m) and scaffolding were used for the installation of the framework and supporting systems. Roof panel fabrication involved placing a rolling mill on the roof. Steel, glass, aluminum panels, aluminum louvers, rock wool, waterproof membrane, steel base plates, and other components were installed using large truck cranes and general contractor tower cranes placed outside the concrete platform. Parametric processing was employed, using BIM software to extract all data such as steel cross-section, length, and quantity. Material orders and processing were individually numbered and matched, and materials arrived on-site according to the construction plan requirements.

[0081] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
