Description

Technical Field

[0001] This invention relates to a method for automatically generating a digital artificial mountain frame, belonging to the field of landscape engineering technology. Background Technology

[0002] In classical garden engineering, for roof gardens and basement slabs, due to limited load-bearing capacity, an elevated frame is often erected on the floor slab, and the surface of the frame is covered with artificial rocks to reduce the load on the artificial rocks and meet the load-bearing capacity requirements of the roof and basement slabs.

[0003] The design of an elevated frame requires comprehensive consideration of multiple factors: First, to achieve the desired rockery shape, the internal frame must be integrated with the overall external form of the rockery; second, the beam and column layout of the elevated frame needs to consider the arrangement of floor beams and columns; finally, the elevated frame also needs to comprehensively consider the weight of the rockery and the load-bearing capacity requirements of the floor slab. These three factors are interrelated and interconnected. Traditional design methods calculate the frame shape based on the rockery's form, then arrange the elevated frame's plan and elevation positions in conjunction with the floor beam and column dimensions, and finally calculate and verify the overall weight. If the weight exceeds the load-bearing capacity, the frame shape and plan / elevation positions need to be adjusted, or the rockery's form needs to be modified before recalculation and verification, until a suitable elevated frame scheme is found.

[0004] This method is cumbersome, computationally intensive, and time-consuming. Summary of the Invention

[0005] The main objective of this invention is to provide a method for automatically generating digital artificial mountain elevated frames to solve the problem of quickly generating artificial mountain elevated frame schemes on rooftops and basement roofs.

[0006] This invention utilizes computer digital technology to quickly and automatically generate artificial mountain scaffolding schemes based on collected artificial mountain data. It can also quickly compare multiple schemes based on the shape and weight of the artificial mountain, and quickly determine the most suitable scaffolding scheme, greatly reducing the time and workload of artificial mountain scaffolding design.

[0007] This invention provides a method for automatically generating a digital artificial rockery's suspended frame, comprising the following steps:

[0008] (1) Conduct digital data acquisition for the artificial mountain design;

[0009] (2) Generate modular grid units inside the artificial mountain;

[0010] (3) Merge the grid of the artificial mountain template;

[0011] (4) Generate the cantilever structure;

[0012] (5) Generate the beam-column structure;

[0013] (6) Calculate the volume and weight of the rockery;

[0014] (7) Adjust and compare the rockery plans.

[0015] Further, step (1) specifically includes: According to the plane and elevation sketch outlines of the preliminary rockery design, raise columns from the plane outline, and according to the elevation outline, push and pull in the plane direction to form columns, and perform an entity intersection operation on the columns to obtain the corresponding rockery contour model Mesh.

[0016] Further, step (2) specifically includes: Set the minimum modulus size of the framework as Lu, set the increasing set of framework height sizes as H = {h1, h2,..., hN}, generate corresponding plane grid units on the plane, for each grid unit that intersects the rockery contour model Mesh, push and pull upward by the set height H respectively, take the grid unit with the highest height and not exceeding the rockery contour model Mesh, at this time, the overall grid unit set U = {u1, u2,..., uN} is generated, and each grid corresponds to a maximum height.

[0017] Further, step (3) specifically includes: Group the grid unit set U according to different heights, place the grid units with the same height in the same set, and obtain grid unit sets T1, T2, T3,... at different elevations; Merge each elevation grid unit set T, set the maximum number of grid units in the horizontal and vertical directions as m, and on this basis, establish an integer programming mathematical model, that is, use a plane unit template with lengths and widths of i and j respectively (0 < i <= m, 0 < j <= m) to fill the cells in T, and the weight of the unit template is taken as the square of the area to obtain the largest grid unit merging result, and each unit template is the corresponding beam and slab.

[0018] Further, step (4) specifically includes: Set the overhanging length of each layer as Lt, for each merged unit group of each layer, first obtain the outermost contour segment, then project all the units higher than this layer to this height, take the difference set of the contour segments intersecting the projection area, obtain the overhanging control line of this layer, push and pull outward by the length Lt from this control line, and try to obtain the overhanging slab set Ct. For any slab in the set, calculate the intersection area with the rockery contour model Mesh respectively. If the proportion of the area exceeding the rockery area is less than the set threshold α, then retain the overhanging slab, and thus obtain the overhanging slabs of each layer.

[0019] Further, step (5) specifically includes: Set the cross-sectional dimensions of the framework structure columns, the cross-sectional dimensions of the beams, and the slab thickness, and generate the corresponding model according to the control line data of the unit modules generated above.

[0020] Further, step (6) specifically includes: setting the unit weight of reinforced concrete ρ1, the unit weight of artificial mountain ρ2, the volume of reinforced concrete frame V1, the volume of artificial mountain outline model Mesh V2, and the volume of internal cavity V3. Then the weight of reinforced concrete frame is ρ1*V1, the weight of artificial mountain stone is ρ2*(V2-V1-V3), the overall weight of artificial mountain stone before adopting the suspended frame is ρ2*V2, and the overall weight after adopting the suspended frame is ρ1*V1+ρ2*(V2-V1-V3).

[0021] Further, step (7) specifically includes: by setting different modulus size Lu, height set H, number of grid unit merging m, cantilever plate length Lt, and threshold α parameter, a variety of artificial mountain cavity schemes are obtained and compared.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 This invention provides a method for automatically generating a digital artificial rockery's suspended frame, comprising the following steps:

[0035] Digital data acquisition of the artificial rockery design;

[0036] Based on the outline of the artificial mountain sketch, the corresponding artificial mountain outline model is obtained through digital acquisition.

[0037] Generate modular grid units inside the artificial mountain;

[0038] Set the minimum modular size of the frame and generate a set of modular grid units inside the artificial mountain.

[0039] Merge the grid of the artificial rockery template;

[0040] The artificial mountain grid set is grouped and merged to obtain the merged grid cell result.

[0041] Generate the cantilever structure;

[0042] Set the cantilever length for each floor, and generate the cantilever structure by projection, difference set calculation, push-pull method, and calculation of intersection area.

[0043] Generate the beam-column structure;

[0044] Set the column cross-section, beam cross-section dimensions, and slab thickness of the frame structure, and generate the corresponding model based on the generated unit module control line data.

[0045] Calculate the volume and weight of the artificial rockery;

[0046] Set parameters such as the unit weight of reinforced concrete, the unit weight of the artificial mountain, the volume of the reinforced concrete frame, the volume of the artificial mountain model, and the volume of the internal cavity, and calculate the weight of the suspended frame.

[0047] Adjust and compare the rockery plans.

[0048] By setting different pattern sizes, height sets, grid cell merging numbers, overhanging plate lengths, and parameters exceeding thresholds, multiple comparison results of rockery cavity plan can be obtained.

[0049] Further, step (1) specifically includes: According to the plane and elevation sketch contours of the preliminary rockery design, raise columns from the plane contour, and push and pull in the plane direction according to the elevation contour to form columns. Perform an intersection operation on the columns to obtain the corresponding rockery contour model Mesh.

[0050] Further, step (2) specifically includes: Set the minimum modular size of the framework as Lu, and set the increasing set of framework height sizes as H = {h1, h2,..., hN}. Generate corresponding plane grid cells on the plane. For each grid cell intersecting with the rockery contour model Mesh, push and pull it upward by the set height H respectively, and select the grid cell with the highest height and not exceeding the rockery contour model Mesh. At this time, the overall generated grid cell set U = {u1, u2,..., uN}, and each grid corresponds to a maximum height.

[0051] Further, step (3) specifically includes: Group the grid cell set U according to different heights, and place the grid cells with the same height in the same set to obtain grid cell sets T1, T2, T3,... at different elevations; Merge each elevation grid cell set T, set the maximum number of grid cells in the horizontal and vertical directions as m, and on this basis, establish an integer programming mathematical model, that is, use a plane unit template with lengths and widths of i and j respectively (0 < i <= m, 0 < j <= m) to fill the cells in T, and the weight of the unit template is the square of the area, to obtain the largest possible grid cell merging result, and each unit template is the corresponding beam and slab.

[0052] Further, step (4) specifically includes: Set the overhanging length of each layer as Lt. For each merged unit group of each layer, first obtain the outermost contour segment, then project all the units higher than this layer to this height, and take the difference set of the contour segments intersecting with the projection area to obtain the outermost control line of this layer. Push and pull outward by the length Lt with this control line to try to obtain the overhanging plate set Ct. For any plate in the set, calculate the intersecting area with the rockery contour model Mesh respectively. If the proportion of the area exceeding the rockery area is less than the set threshold α, then keep the overhanging plate, and thus obtain the overhanging plates of each layer.

[0053] Further, step (5) specifically includes: Set the cross-sectional dimensions of the framework structure columns, beam cross-sectional dimensions, and plate thickness, and generate the corresponding model according to the above-generated unit module control line data.

[0054] Further, step (6) specifically includes: setting the unit weight of reinforced concrete ρ1, the unit weight of artificial mountain ρ2, the volume of reinforced concrete frame V1, the volume of artificial mountain outline model Mesh V2, and the volume of internal cavity V3. Then the weight of reinforced concrete frame is ρ1*V1, the weight of artificial mountain stone is ρ2*(V2-V1-V3), the overall weight of artificial mountain stone before adopting the suspended frame is ρ2*V2, and the overall weight after adopting the suspended frame is ρ1*V1+ρ2*(V2-V1-V3).

[0055] Further, step (7) specifically includes: by setting different modulus size Lu, height set H, number of grid unit merging m, cantilever plate length Lt, and threshold α parameter, a variety of artificial mountain cavity schemes are obtained and compared.

[0056] In one embodiment of the present invention, the method for automatically generating a digital artificial mountain elevated frame is as follows: An artificial mountain is located on the roof slab of a basement garage. The roof slab has limited load-bearing capacity, so an elevated structure is designed for the artificial mountain. The artificial mountain has a total length of approximately 13 meters, a width of approximately 6 meters, and a maximum height of approximately 3.5 meters.

[0057] The specific implementation plan consists of the following six steps:

[0058] 1. For example Figure 2 As shown, based on the design plan and elevation drawings, the rockery is first pushed and pulled into shape, and then the intersection of the solids is calculated to obtain a rough model of the rockery.

[0059] 2. Set the minimum module of the frame to 1.2m, and set the frame height dimensions to increase in increments H={1.4m, 3m}. Generate the following inside the artificial rockery: Figure 3 The grid cells shown are of different heights, with some cells being 1.4m high and others being 3m high.

[0060] 3. Set the maximum number of grid cells to be merged to 4, such as... Figure 4 As shown, the merging operation is performed on the 1.4m and 3m high grid cells respectively to obtain the merged cell.

[0061] 4. Set the cantilever length of the cantilever board to 0.6m, such as... Figure 5 As shown, generate the cantilever board at each height.

[0062] 5. Set the column cross-section dimensions of the frame structure to 0.3m * 0.3m, the beam cross-section dimensions to 0.3m * 0.45m, the floor slab thickness to 0.12m, and the cantilever slab thickness to 0.12m. The resulting frame model is as follows: Figure 6As shown, the unit weight of C20 reinforced concrete is set to ρ1 = 2.4 t / m3, and the unit weight of the artificial rockery is set to ρ2 = 2.7 t / m3. Statistical analysis of the model information yields the following: reinforced concrete frame volume V1 = 9.4 m3, artificial rockery model mesh volume V2 = 90.7 m3, and internal cavity volume V3 = 33.5 m3. Therefore, the weight of the reinforced concrete frame is ρ1*V1 = 22.56 t, and the weight of the artificial rockery is ρ2*(V2-V1-V3) = 129.06 t. Before using the suspended frame, the total weight of the artificial rockery was approximately ρ2*V2 = 244.89 t. After using the suspended frame, the total weight is approximately ρ1*V1 + ρ2*(V2-V1-V3) = 151.62 t. Using the suspended frame reduces the weight by approximately 93.27 t, or about 38%.

[0063] 6. For example Figure 7 Different preset parameter combinations are made for the frame module of 1m, 1.2m, 1.5m and the height set of {1.2m, 2.5m}, {1.4m, 3m}. Other preset parameters are referred to steps 1 to 5 to obtain different generation schemes and compare multiple schemes.
