Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a method for dividing a metal curtain wall, a metal curtain wall, a computer device, and a program product. Background Technology

[0002] Metal panel curtain walls are increasingly widely used in various types of buildings. Compared to stone curtain walls, they offer advantages such as lighter weight, easier molding, customizable colors, and convenient installation. Besides large-scale applications, they are most commonly used in various shaped curtain walls, particularly in cantilevered box-type metal curtain walls located between floors or at the top of buildings. These curtain walls serve both decorative and sun-shading functions. These curtain walls are often arranged around the perimeter of the building, forming a cantilevered box shape. However, due to variations in unit layout and building shape, their length from the building structure varies. How to segment cantilevered box-type metal curtain walls of different lengths and how to splice them at corners becomes a key implementation issue, requiring consideration of panel economy, installation convenience, functional construction, and aesthetic appeal of the splicing.

[0003] The current technical solution involves first dividing each section of the cantilevered box-type metal curtain wall into individual panels, then splicing them at the corners, and finally making local adjustments to the panel layout. Due to the lack of a systematic panel control strategy, problems such as unreasonable panel dimensions, misalignment of panels at corners, and unsightly seams at joints are prone to occur. Specifically, the following issues are likely to arise: 1. Within the same section, the top and bottom panels along the circumference of the shape are often independently divided without coordination or overall planning. The top, bottom, and head shapes are prone to having panels that are too large or too small, resulting in significant problems with economy and ease of installation. 2. At corner locations, due to the lack of systematic planning and control strategies, 90° splicing of cantilevered box-type metal curtain walls of different lengths can easily result in misaligned panel seams, which is extremely unsightly and even the drip edge structure cannot be connected. 3. Due to the lack of a unified segmentation strategy for each section, the spatial seam patterns at the 90° splicing points of the box-type cantilever design are diverse, making it impossible to determine and control them in advance, which can easily lead to unsightly issues. Summary of the Invention

[0004] This invention provides a metal curtain wall segmentation method, a metal curtain wall, a computer device, and a program product that improves economic efficiency and installation convenience.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A method for dividing a metal curtain wall into sections, wherein the metal curtain wall is a cantilevered box-type metal curtain wall with corners, the method comprising the following steps: Step 1: Select the box-shaped section C1 with the largest total horizontal length L1 at the top, and determine the horizontal division of the top metal plate of C1; Step 2: Determine the vertical division of the top metal plate of C1; Step 3: Determine the horizontal division of the bottom metal plate of C1 based on the horizontal division of the top metal plate of C1; Step 4: Determine the vertical division of the bottom metal plate of C1; Step 5: Select the box-shaped section C2 with the smallest total horizontal length L3 at the top, and determine the vertical division of the metal plate at the top of C2; Step 6: Determine the horizontal division of the top metal plate of C2; Step 7: Determine the vertical division of the bottom metal plate of C2 based on the vertical division of the top metal plate of C2; Step 8: Determine the horizontal division of the bottom metal plate of C2.

[0006] Step 2, determining the vertical division of the top metal plate of C1, includes: Step 21: Define the end cap specifications based on the most economical unfolded board width, and determine the length A1 of the top end cap; Step 22: Obtain the total dimensions of the top transition plate according to H1 = total horizontal length of the top L1 - A1 - B1, where B1 is determined by considering the metal plate folding processing and installation requirements, for example, B1 ≥ 100mm (initially 100mm). Determine whether H1 is greater than the control length of the transition plate K1 (K1 can be 1500mm). If it is not greater, the top transition plate is one piece with length A2 = H1; if it is greater, the equation H1 = K1 * n´ + h is satisfied, where n´ is the largest positive integer that makes the equation true, and h > 0. Step 23: Determine B2 within the head styling plate length A5 by considering the metal plate folding and drip processing requirements. B2 can be 100mm. Then determine whether the head styling plate length A5+h is greater than the styling plate control length K2 (K2 can be 1500mm). If it is not greater, then B1´=B1+h, A2=K1, n=n´; if it is greater, then A2=H1 / n, where n is the smallest positive integer that makes A2≤K1, B1´=B1, and update the head styling plate length A5=A5-B1+B1´.

[0007] Step 4, determining the vertical division of the bottom metal plate of C1, includes: Step 41: Set the drip structure position. According to H2 = total horizontal length of bottom L2 - B2, obtain the total size of bottom transition plate and bottom closing plate, which satisfies the equation H2 = K1 * m´ + f, where m´ is the largest positive integer that makes the equation true, and f > 0, where K1 is the control length of transition plate. Step 42: Next, determine whether f is greater than the bottom finishing plate control length K3 (K3 can be 150mm). If it is greater, then A4=f, A3=K1, m=m´; if it is not greater, then A3=A4=H2 / m, where m is the smallest positive integer that makes A3=A4≤K1.

[0008] Step 6, determining the horizontal division of the top metal plate of C2, includes: Step 61: Determine the joint line Q1 based on the apex of the inside and outside corners where the top surfaces of the two decorative curtain walls meet at the corner position. Take the intersection of the joint line Q2 of the top decorative panel and the top transition panel on C1 and line Q1 as the control point P1. Draw a perpendicular line from P1 to Q2 to determine the control dimensions of the top decorative panel on the top surface of C2. Step 62: The seam line Q3 between the top transition plate and the top finishing plate on C1 is perpendicular to the top transition plate. The intersection of Q3 and line Q1 is P2. Draw a perpendicular line to Q3 with P2 as the endpoint, thus initially dividing the top surface of C2 into horizontal sections. Starting from the top transition plate closest to the head, merge the adjacent sections. The length of the merged section should satisfy A2≤K1, where K1 is the control length of the transition plate. After one merging is completed, start the merging process again from the nearest unmerged transition plate to obtain the final horizontal sectioning of the top surface of C2.

[0009] Step 8, determining the horizontal division of the bottom metal plate of C2, includes: Step 81: At the intersection of the two bottom flat surfaces of the corner, the seam line Q4 is obtained. The intersection of the drip line Q5 on C1 and the line Q4 is taken as the control point P3. A perpendicular line is drawn from the control point P3 to Q5, thereby determining the bottom drip line of C2. Step 82: The seam line Q6 between the bottom transition plate and the bottom finishing plate of C1 is perpendicular to Q6, with P4 as the intersection point of Q6 and Q4. This creates an initial horizontal division of the bottom surface of C2. Starting from the bottom transition plate closest to the top, merge the adjacent segmented plates. The length of the merged plate should satisfy A3≤K1, where K1 is the control length of the transition plate. After one merging, start the merging process again from the nearest unmerged transition plate to obtain the final horizontal division of the bottom surface of C2.

Determine whether H1 is greater than the control length of the transition plate K1 (K1 can be 1500mm). If it is not greater, the top transition plate is one piece with length A2 = H1; if it is greater, the equation H1 = K1 * n´ + h is satisfied, where n´ is the largest positive integer that makes the equation true, and h > 0. Step 23: Determine B2 within the head styling plate length A5 by considering the metal plate folding and drip processing requirements. B2 can be 100mm. Then determine whether the head styling plate length A5+h is greater than the styling plate control length K2 (K2 can be 1500mm). If it is not greater, then B1´=B1+h, A2=K1, n=n´; if it is greater, then A2=H1 / n, where n is the smallest positive integer that makes A2≤K1, B1´=B1, and update the head styling plate length A5=A5-B1+B1´. Step 3: Determine the horizontal division of the bottom metal plate of C1 based on the horizontal division of the top metal plate of C1; Step 4: Determine the vertical division of the bottom metal plate of C1; including: Step 41: Set the position of the drip structure. According to H2 = total horizontal length of the bottom L2 - B2, obtain the total size of the bottom transition plate and the bottom closing plate, which satisfies the equation H2 = K1 * m´ + f, where m´ is the largest positive integer that makes the equation true, and f > 0. Step 42: Next, determine whether f is greater than the bottom finishing plate control length K3 (K3 can be 150mm). If it is greater, then A4=f, A3=K1, m=m´; if it is not greater, then A3=A4=H2 / m, where m is the smallest positive integer that makes A3=A4≤K1. Step 5: Select the box-shaped section C2 with the smallest total horizontal length L3 at the top, and determine the vertical division of the metal plate at the top of C2; Step 6: Determine the horizontal division of the top metal plate of C2; including: Step 61: Determine the joint line Q1 based on the apex of the inside and outside corners where the top surfaces of the two decorative curtain walls meet at the corner position. Take the intersection of the joint line Q2 of the top decorative panel and the top transition panel on C1 and line Q1 as the control point P1. Draw a perpendicular line from P1 to Q2 to determine the control dimensions of the top decorative panel on the top surface of C2. Step 62: The seam line Q3 between the top transition plate and the top finishing plate on C1 is perpendicular to line Q3 at point P2. P2 is the point where Q3 intersects with line Q1. This creates an initial horizontal division of the top surface of C2. Starting from the top transition plate closest to the top, multiple adjacent division plates are merged. The length of the merged plate should satisfy A2≤K1. After one merging, the merging process is repeated starting from the nearest unmerged transition plate to obtain the final horizontal division of the top surface of C2. Step 7: Determine the vertical division of the bottom metal plate of C2 based on the vertical division of the top metal plate of C2; Step 8: Determine the horizontal division of the bottom metal plate of C2; including: Step 81: At the intersection of the two bottom flat surfaces of the corner, the seam line Q4 is obtained. The intersection of the drip line Q5 on C1 and the line Q4 is taken as the control point P3. A perpendicular line is drawn from the control point P3 to Q5, thereby determining the bottom drip line of C2. Step 82: The seam line Q6 between the bottom transition plate and the bottom finishing plate of C1 is perpendicular to Q6, with P4 as the intersection point. P4 is the perpendicular line to Q6, thus initially dividing the bottom surface of C2 into horizontal sections. Starting from the bottom transition plate closest to the head, merge the adjacent sections. The length of the merged section satisfies A3≤K1. After one merge, start the merging process again from the nearest unmerged transition plate to obtain the final horizontal sectioning of the bottom surface of C2. Step 9: Connect P3 with the outer endpoint of line Q1 to obtain the seam line Q7 for the corner shape.

[0011] The process includes step 10 after step 9: optimizing and adjusting the corner position layout.

[0014] A computer program product includes a computer program that, when executed by a processor, implements the steps of the method described above.

[0015] The beneficial effects of this invention are as follows: The metal curtain wall segmentation method, metal curtain wall, computer device, and program product of this invention, through the above steps, comprehensively consider the segmentation strategy of the circumferential dimensions of the shape. Within the same section, the top and bottom panels along the circumferential dimensions of the shape are segmented in a coordinated and balanced manner, effectively avoiding the problem of excessively large or small panel sizes on the top, bottom, and head surfaces, thus improving economy and installation convenience. Furthermore, regarding the segmentation and splicing problem of different length shapes at corner locations, based on two key control elements—the splicing seam of the head panel and the drip line at the bottom—the segmentation of the larger-sized section is mapped to the smaller-sized section, resulting in the preliminary segmentation of the smaller-sized section. Then, through merging and optimization, the final segmentation of the smaller-sized section is obtained. This ensures optimal segmentation for both large and small-sized sections while also guaranteeing the consistency and continuity of the panel seams, improving the overall aesthetics of the shape. Moreover, based on the defined segmentation method, the spatial seams at corners are predictable and controllable in advance, which is beneficial for design evaluation and optimization.

[0018] Figure 3 for Figure 2 The diagram shows the segmentation process in the metal curtain wall segmentation method. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and examples.

[0020] In this embodiment, as Figures 1 to 3 As shown, this embodiment provides a method for dividing a metal curtain wall into sections. The metal curtain wall is a cantilevered box-type metal curtain wall with corners, which is fixed to the main structure 7. The method includes the following steps.

[0021] Step 1, within the top outline area (e.g.) Figure 3 In section S1), select the box-shaped section C1 with the largest total horizontal length L1 at the top, and determine the horizontal division of the top metal plate of C1 (e.g., Figure 3 (S2), taking into account the stress on the keel and economy, the horizontal grid can be taken as about 1200mm.

[0022] Step 2: Determine the vertical division of the top metal plate of C1. This embodiment specifically includes: Step 21: Define the total length A1 of the top edge panel along the circumference of the box-shaped structure based on the most economical unfolded panel width. The most economical unfolded panel width can be taken as 1500mm to determine the length A1 of the top edge panel 1 (e.g., Figure 3 (S3) Step 22: Based on H1 = total horizontal length of the top L1 - A1 - B1, obtain the total dimensions of the top transition plate 2. Considering the metal plate folding and installation requirements, where B1 ≥ 100mm (initially 100mm), determine whether H1 is greater than the control length K1 of the transition plate (K1 can be 1500mm). If it is not greater, the top transition plate is one piece with length A2 = H1; if it is greater, the equation H1 = K1 * n´ + h is satisfied, where n´ is the largest positive integer that makes the equation true, and h > 0. Step 23: Considering the requirements for metal plate folding and drip processing, B2 in the head shaping plate length A5 can be taken as 100mm. Then determine whether the length A5+h of the head shaping plate 3 is greater than the shaping plate control length K2 (K2 can be taken as 1500mm). If it is not greater, then B1´=B1+h, A2=K1, n=n´; if it is greater, then A2=H1 / n, where n is the smallest positive integer that makes A2≤K1, B1´=B1, and update the head shaping plate length A5=A5-B1+B1´ (e.g., ...). Figure 3 in S4).

[0023] The above steps take into account both the top and head styling parts, using the length A5 of the head styling plate as an adjustment, and using the styling plate control length K2 as a benchmark to determine the optimal length A2 of the top transition plate.

[0024] Step 3: Determine the horizontal division of the bottom metal plate of C1 based on the horizontal division of the top metal plate of C1 (e.g., Figure 3 S5).

[0025] Step 4: Determine the vertical division of the bottom metal plate of C1. This embodiment specifically includes: Step 41, Set the position of drip structure 4 (e.g.) Figure 3 According to H2 = total horizontal length of bottom L2 - B2, the total dimensions of bottom transition plate 5 and bottom closing plate 6 are obtained, which satisfy the equation H2 = K1 * m´ + f, where m´ is the largest positive integer that makes the equation true, and f > 0; Step 42: Next, determine whether f is greater than the bottom finishing plate control length K3 (K3 can be 150mm). If it is greater, then A4=f, A3=K1, m=m´; if it is not greater, then A3=A4=H2 / m, where m is the smallest positive integer that makes A3=A4≤K1 (e.g., f is the bottom finishing plate control length K3). Figure 3 S7).

[0026] The above steps take into account both the bottom transition plate and the finishing plate, and determine the optimal length A3 of the bottom transition plate based on the control length K3 of the bottom finishing plate.

[0027] Step 5: Select the box-shaped section C2 with the smallest total horizontal length L3 at the top, and determine the vertical division of the top metal plate of C2 (e.g., Figure 3 (S8), taking into account the stress on the keel and economy, the vertical grid can be taken as about 1200mm.

[0028] Step 6: Determine the horizontal division of the top metal plate of C2. This embodiment specifically includes: Step 61: Determine the joint line Q1 based on the apex of the inner and outer corners where the top surfaces of the two decorative curtain walls meet at the corner location. Use the intersection of the joint line Q2 (between the head decorative panel and the top transition panel on C1) and line Q1 as control point P1. Draw a perpendicular line from P1 to Q2, thus determining the control dimensions of the head decorative panel on the top surface of C2. Ensure that Q2 passes through P1 to guarantee continuity at the corner (e.g., ...). Figure 3 (S9) Step 62: The straight line Q3 between the top transition plate and the top finishing plate on C1, with the intersection of Q3 and line Q1 at point P2, is used to draw a perpendicular line to Q3 with P2 as the endpoint, thus initially dividing the top surface of C2 into horizontal sections (e.g., Figure 3 Starting from the top transition plate closest to the head, merge multiple adjacent segmented plates. The length of the merged plate should satisfy A2≤K1. After one merge, start the merging process again from the nearest unmerged transition plate to obtain the final horizontal segmentation of the top surface of C2 (e.g., S10). Figure 3 (S11). This step first maps the top surface of C1 to obtain the initial top surface grid of C2 through P2, and then merges them to make the top surface grid of C2 optimal and ensure that the top surface seams of C1 and C2 are aligned at the corner.

[0029] Step 7: Determine the vertical division of the bottom metal plate of C2 based on the vertical division of the top metal plate of C2 (e.g., Figure 3 (S12).

[0030] Step 8: Determine the horizontal division of the bottom metal plate of C2. This embodiment specifically includes: Step 81: At the intersection of the two bottom flat surfaces of the corner, obtain the seam line Q4. Use the intersection of the drip line Q5 on C1 and line Q4 as control point P3. Draw a perpendicular line from control point P3 to Q5, thus determining the bottom drip line 4 of C2. Ensure the drip line at the corner is continuous through P3 (e.g., ...). Figure 3 (S13) Step 82: The straight line Q6 between the bottom transition plate and the bottom finishing plate on C1, with the intersection of Q6 and Q4 at P4, is used to draw a perpendicular line to Q6 with P4 as the endpoint, thus initially dividing the bottom surface of C2 into horizontal sections (e.g., Figure 3(S14); Starting from the bottom transition plate closest to the head, merge multiple adjacent segmented plates, the length of the merged plate satisfies A3≤K1; after one merge, start the merging process again from the nearest unmerged transition plate to obtain the final horizontal segmentation of the bottom surface of C2 (e.g., Figure 3 (S15). This step first maps the bottom surface of C1 to obtain the initial bottom surface of C2 through P4, and then merges them to make the bottom surface of C2 optimal and ensure that the bottom surface seams of C1 and C2 are aligned at the corner; K1 is definitely larger than K3 in reality, so merging will not affect the bottom finishing plate.

[0031] Step 9: Connect P3 with the outer endpoint of line Q1 to obtain the corner seam line Q7 (e.g., Figure 3 S16).

[0032] Step 10: Optimize and adjust the corner layout. This mainly involves merging or splitting the dividing panels to make their shapes more standard and square, thus resulting in a more reasonable overall shape and size after dividing the panels. For example... Figure 3 In S17, the top corner division breaks the trapezoid into triangles and rectangles, resulting in a more square shape. For example... Figure 3 The S18 model features a bottom corner grid design that adjusts irregular shapes to a more square shape, resulting in a more harmonious length-to-width ratio.

[0033] This embodiment also provides a metal curtain wall using the above-described metal curtain wall segmentation method, the shape of which after segmentation is as follows: Figure 3 As shown in the image.

[0034] The metal curtain wall segmentation method in this embodiment can be implemented through a computer program. AutoCAD can be chosen as the graphics platform. To automate the metal panel segmentation process, AutoCAD is further developed using the ObjectARX development environment and application programming interface (API) based on the C++ programming language. The written program is compiled and linked to generate an ObjectARX application. An ObjectARX application is essentially a Windows Dynamic Link Library (DDL) program that shares the address space with AutoCAD. It can directly call AutoCAD's core functions and directly access the core data structures and code of the AutoCAD database, enabling the extension of AutoCAD's inherent functionality during runtime and the creation of new commands that fully enjoy the privileges of AutoCAD's inherent commands.

[0035] The main operational steps for implementation are as follows: Draw the cross-sectional outline of the box-shaped metal curtain wall on both sides of the corner at a 1:1 scale in the AutoCAD graphical interface. The cross-sectional outline is identified by the command in the new menu bar, and key control parameters such as the total length of the metal curtain wall on both sides of the corner, the panel grid size parallel to the circumference of the shape, the control length K1 of the transition plate, the control length K2 of the shape plate, the control length K3 of the bottom closing plate, and the control dimensions B1 and B2 are entered in the interactive operation interface. The program automatically draws the three-dimensional outline of the box-type metal curtain wall on both sides of the corner, and splices the three-dimensional outline with the inside corner as the base point; it calls the main function of segmentation processing to automatically segment according to the segmentation process of this patent method; Based on the calculation results of the segmentation processing main function, the curtain wall segmentation graphic drawing function is called to complete the automatic drawing of the final box-type metal curtain wall segmentation 3D graphic.

[0036] Therefore, this embodiment also provides a computer device, including a memory, a processor, and a computer program stored in the memory, wherein the processor executes the computer program to implement the steps of the method described above.

[0037] This embodiment also provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the method described above.
