Description

Technical Field

[0001] The present invention relates to the technical field of building curtain wall design, and in particular to a three-dimensional design method, system and medium for building curtain walls based on a BIM model. Background Art

[0002] The curtain wall is the exterior wall of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The curtain wall is composed of panels and a supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability of itself, and does not bear the effects of the main structure. It is an exterior protective structure or decorative structure of the building.

[0003] Existing improvements for curtain wall design usually analyze the connection method and curtain wall materials of the curtain wall. For example, in a patent application with publication number CN106484944A, a curtain wall design method based on BIM is disclosed. The scheme is to establish a three-dimensional part model and a work plane, calculate the parameters of each three-dimensional part, load the three-dimensional part model on the work plane, and finally scale and position the accessories to complete the panel assembly. However, the existing improvement method lacks analysis of the position of windows that can be retained in the curtain wall and the shape of the windows. This will result in the need to manually splice the curtain wall materials when designing the curtain wall, and determine the position of the windows based on the real-time splicing situation. The shape of the windows also requires further manual analysis. In view of this, it is necessary to improve the existing curtain wall design. Summary of the invention

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Example 1, first aspect, please refer to Figure 1As shown, the present invention provides a three-dimensional design system for building curtain walls based on a BIM model, including a model processing module and a data calculation module; the model processing module is used to obtain a BIM model of a building, the BIM model including column width, column spacing, column length, horizontal frame width and floor spacing; and is also used to display all curtain wall quantities and covering wall quantities in the BIM model;

[0058] The model processing module is configured with a model analysis strategy, which includes:

[0059] Obtain the BIM model of the building, and obtain the column width, column spacing, column length, cross frame width, and floor spacing from the BIM model;

[0060] See also Figure 3 As shown, Figure 3 To obtain the front view of the BIM model of the building, T1 is the floor spacing, T2 is the horizontal frame width, T3 is the column width of column 1, T4 is the column width of column 2, T5 is the first column spacing, and T6 is the second column spacing; the result of calculating 5 times T1 plus 4 times T2 is the column height;

[0061] Figure 3 There are 6 horizontal frames in total, indicating that the building is 6 stories high; Column 1 and Column 2 indicate that there are two columns of different widths in the BIM model;

[0062] It should be noted that since the height of the first floor of the building is higher than that of other floors, and there may be shear walls or window walls on the outside of the building, or other curtain walls that need to be designed with more emphasis on appearance, the present invention does not analyze the design method of the curtain wall of the first floor.

[0063] The data calculation module is used to analyze and calculate the column width, and output the number of types based on the calculation results; calculate the number of types and the column length, and output the number of covered walls based on the calculation results; and calculate the column spacing, and output the curtain wall width based on the calculation results; calculate the horizontal frame width and the floor spacing, and output the reserved window length and the curtain wall length; the data calculation module is also used to obtain the total number of column spacing and the total number of floor spacing, calculate the total number of column spacing and the total number of floor spacing, and output the number of curtain walls;

[0064] The data calculation module is configured with a wall-covering calculation strategy, which includes:

[0065] Sort all column widths in ascending order to obtain a vertical width sequence; number the leftmost column width in the vertical width sequence as 1;

[0066] Set the sliding window size to 2, place the sliding window at the leftmost side of the vertical and horizontal sequence, and perform duplicate judgment processing;

[0067] Duplicate judgment processing includes:

[0068] Determine whether the widths of two columns in the sliding window are equal. If they are equal, set the number of the width of the right column in the sliding window to be the same as the number of the width of the left column in the sliding window;

[0069] If they are not the same, set the number of the right column width in the sliding window to the number of the left column width in the sliding window plus one; move the sliding window to the right by one column width, repeat the repeated judgment process, and stop the repeated judgment process when the sliding window moves to the rightmost side of the vertical width sequence.

[0070] In the specific implementation, the front view of the building BIM model is used Figure 3 For example, Figure 3 There are 12 columns in total, 6 of which are column 1 and 6 are column 2. If the width of column 1 is 30 cm and the width of column 2 is 40 cm, then the length-width sequence is Figure 4 As shown, A1 and A2 are both sliding windows, A1 is the state when the sliding window is placed at the leftmost side of the vertical width sequence, and A2 is the position of the sliding window after executing 5 repeated judgment processes; the 1 under the leftmost column width indicates that it is numbered 1;

[0071] When the sliding window is at A1, repeated judgment processing is performed, and the width of the column on the right side of the sliding window is numbered 1, and then the sliding window moves one unit to the right, and so on, and all 60 numbers are set to 1; when the sliding window slides to A2, the width of the column on the left side of the sliding window is numbered 1, and the widths of the two columns in the window are not equal, then the width of the column on the right side is set to 1+1=2; then it slides one unit to the right until all 80 numbers are set to 2.

[0072] Get the number of column widths of each number, marked as the number of types;

[0073] Use the quantity calculation formula to calculate the length of the column and output the number of single walls;

[0074] The quantity calculation formula is configured as:

[0075] S i =⌈LC / k1⌉; where S i is the number of single walls with column width numbered i, Lc is the column length, k1 is a constant, and ⌈⌉ is the rounding symbol;

[0076] Calculate the product of the number of single walls and the number of types, and mark it as the number of covered walls.

[0077] In specific implementation, Figure 3 For example, the wall covering is used to cover the column in a one-to-one ratio, and the length and width used are the same as the length and width of the corresponding covered column. The number of types of column 1 is 6. If the floor spacing is 3.5m and the horizontal frame width is 10cm, the column length is 17.9m; then use the quantity calculation formula to calculate, in which k1 is the length of the wall covering material used. Taking 50cm as an example, the number of single walls required for each column is ⌈17.9 / 0.5⌉=36; and then the number of wall coverings required for the building surface corresponding to column 1 and column 2 in the front view is 36×6=216.

[0078] The data calculation module is also configured with a curtain parameter calculation strategy, which includes:

[0079] Use the glass width calculation formula to calculate the column spacing and output the curtain wall width;

[0080] The glass width calculation formula is configured as: BK=ZJ / 2; where BK is the curtain wall width and ZJ is the column spacing;

[0081] by Figure 3 For example, Figure 3 There are two different column spacings of 120cm and 140cm respectively, so two curtain walls with widths of 60cm and 70cm are required;

[0082] Calculate the sum of the horizontal frame width and the floor spacing, and mark it as the required length of the curtain wall;

[0083] Use the curtain length calculation formula to calculate the required length of the curtain wall and output the length of the first curtain wall;

[0084] The curtain length calculation formula is configured as: BL=XL / 2; where BL is the length of the first curtain wall, and XL is the required length of the curtain wall;

[0085] In specific implementation, if the floor spacing is 3.5m and the horizontal frame width is 10cm, then XL is 3.6m, and BL = 1.8m;

[0086] Use the window length calculation formula to calculate the required length of the curtain wall and output the predicted window length;

[0087] The window length calculation formula is configured as: CL=BL-k2; where CL is the predicted window length, XL is the curtain wall length, and k2 is a constant;

[0088] In the specific implementation, k2 is set to 1.2, which means that a window is set 1.2m away from the floor, then CL = 0.6m, which means the length of the window is 0.6m;

[0089] Analyze CL. When CL is greater than or equal to BK, mark the predicted window length as the reserved window length, mark k2 as the second curtain wall length, and output the reserved window length and curtain wall length.

[0090] When CL is less than BK, mark BK as the reserved window length, mark BL-BK as the second curtain wall length, and output the reserved window length and curtain wall length;

[0091] like Figure 5 As shown, Figure 5 Show the length and width of the window for two different stud spacings. Figure 5 In the middle display, the window is displayed as a horizontal rectangle, which is not beautiful in appearance. Therefore, when the width of the window is greater than the length, the window is displayed as a square by increasing the length of the window, which is the situation on the right side of Figure 5, thereby improving the aesthetics of the curtain wall.

[0092] The data calculation module is also configured with a scene number calculation strategy, which includes:

[0093] Get the total number of each column spacing from the BIM model and mark it as the number of vertical spans;

[0094] Get the total number of floor spacing from the BIM model, marked as the number of spans;

[0095] Calculate the product of the number of vertical and horizontal spans for each column spacing, and mark it as the second curtain wall number;

[0096] Calculate the product of the second curtain wall number and the first increased value, and mark it as the first curtain wall number;

[0097] Output curtain wall quantity;

[0098] In a specific implementation, the first increase value is set to 3, such as Figure 5 As shown on the left, each frame requires 3 curtain walls with a width of 60cm and a length of 180cm, and requires a curtain wall with a width of 60cm and a length of 120cm; Figure 3 As shown, there are 6 frames with a column spacing of 120 cm on each floor, so there are 30 frames with a column spacing of 120 cm on the five floors, that is, the second curtain wall number is 30, indicating that the surface where the building front view is located requires 30 curtain walls with a width of 60 cm and a length of 120 cm; at this time, the first curtain wall number is equal to 30×3=90, indicating that 90 curtain walls with a width of 60 cm and a length of 180 cm are required;

[0099] The same applies to the frame with a column spacing of 140cm.

[0100] The model processing module is also configured with a model adding strategy, which includes:

[0101] In the BIM model of the building, connect each building material corresponding to the wall covering quantity to the wall corresponding to the column width corresponding to the wall covering quantity, and mark the BIM information of the building material, including but not limited to specification parameters and connection methods;

[0102] The area enclosed by the column spacing and floor spacing corresponding to the same area in the BIM model is defined as a frame; the frame is divided into four parts with the geometric center of the frame as the dividing point, and each part is marked as the upper left frame, lower left frame, upper right frame and lower right frame based on the spatial position;

[0103] In the BIM model of the building, the curtain wall material corresponding to the first curtain wall number is connected to each upper left frame, upper right frame and lower right frame; the curtain wall material corresponding to the second curtain wall number is connected to each lower left frame at the reserved window length from the upper left frame, and the BIM information of the curtain wall material is marked.
