Description

Technical Field

[0001] The present application relates to the field of computer-aided design, and more specifically, to a method, device, storage medium, and electronic device for rapid modeling. Background Art

[0002] Structural engineers, as professionals specializing in the analysis and design of building structures, ensure the safety and stability of building structures through precise calculations and careful material selection. In the current workflow, structural engineers are responsible for arranging structural components such as shear walls, beams, and floor slabs based on the architectural design drawings provided by the architect. This process primarily relies on visual inspection of the drawings, combined with personal expertise and extensive experience, to accurately locate the shear wall settings and the starting and ending points of the beams. Subsequently, the dimensions of the shear walls and beams, as well as their left and right eccentric positions, must be carefully adjusted based on the location and width of the building walls. The design of floor slabs also relies on the structural engineer's understanding of architectural diagrams or textual descriptions to set appropriate parameters for each floor slab.

[0003] However, existing technical implementation methods rely heavily on manual labor, and architectural floor plans are often subject to constant adjustment. This forces structural engineers to make numerous repetitive revisions, inevitably increasing the likelihood of errors. Therefore, improving the efficiency of structural component layout has become a key issue that needs to be addressed in the industry. Summary of the Invention

[0087] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. The components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0088] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0089] It should be noted that: like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0090] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the inventive product is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0091] In addition, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements not only includes those elements but also includes other elements not expressly listed or elements inherent to such process, method, article or apparatus. Without further limitation, an element qualified by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element.

[0092] In addition, terms such as "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0093] Based on the above statements, as introduced in the background art, structural engineers rely on professional knowledge and experience to manually arrange building structure components, but this method is inefficient and error-prone due to frequent adjustments in building floor plans, and improving the arrangement efficiency has become an urgent need in the industry.

[0094] Based on the discovery of the above technical problems, the inventors have proposed the following technical solutions through creative labor to solve or improve the above problems. It should be noted that the defects existing in the above solutions in the prior art are the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the embodiments of the present application below for the above problems should be the contributions made by the inventors to the present application during the invention creation process, and should not be understood as the technical content known to those skilled in the art.

[0095] In view of this, this embodiment provides a method for rapid modeling. In this method, an electronic device receives and responds to a user's box selection operation on a building design drawing, and determines a drawing area from the building design drawing; and generates shear walls according to the drawing area. Thus, compared with structural designers relying on professional knowledge and experience to draw shear walls one by one, automatically generating shear walls based on the box-selected drawing area greatly improves the drawing efficiency.

[0096] It should be noted that the electronic device implementing this method can be, but is not limited to, a mobile terminal, a tablet computer, a laptop computer, a desktop computer, a server, etc. The server group can be centralized or distributed (for example, the server can be a distributed system). In some embodiments, the server can be local or remote relative to the user terminal. In some embodiments, the server can be implemented on a cloud platform; by way of example only, the cloud platform can include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, etc., or any combination thereof. In some embodiments, the server can be implemented on an electronic device having one or more components. When the electronic device is a server, the user terminal and the server are communicatively connected via a network, and a structural designer can access the server through the user terminal and design building structure components in the operation interface provided by the server. The user terminal can be, but is not limited to, a mobile terminal, a tablet computer, a laptop computer, etc. For example, the user terminal can be a laptop computer.

[0097] To make the solution provided in this embodiment clearer, the following takes the server as the electronic device implementing this method and elaborates on each step of the method in combination with Figure 1 However, it should be understood that when implementing this method through the server, the user terminal converts the user's drawing operation into an operation instruction and sends it to the server, so that the server can indirectly receive the user's drawing operation through the user terminal and respond. The operations in the flowchart may not be implemented in sequence, and steps without a logical context relationship can be reversed or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flowchart or remove one or more operations from the flowchart under the guidance of the content of this application. As Figure 1 shown, the method includes:

[0098] S1, receiving and responding to the user's selection operation on the building design drawing, and determining a drawing area from the building design drawing.

[0099] It should be noted that the above building design drawing is pre-designed by an architect. The structural designer needs to design structural members on the basis of the building design drawing, such as shear walls, beams, floor slabs, etc. In this embodiment, the structural designer can use input devices such as a mouse, a touchpad, a touch screen, etc. to control the mouse pointer to determine a drawing area in the building design drawing. Exemplarily, as Figure 2 shown, the server provides an interface for displaying and editing the building design Figure 10 and it should be noted that due to area limitations, Figure 2Only a part of the complete building design drawing is shown. Based on this interface, the structural designer can move the mouse pointer 11 to the starting position 12 of the area in the building design Figure 10 where the area to be selected is desired, then press and hold the left mouse button, and at the same time slowly drag the mouse. The mouse pointer 11 will move along and draw a drawing area 13 on the interface. The size of the drawing area 13 will change synchronously with the movement of the mouse pointer 11. Therefore, continue to drag the mouse pointer 11 until the selection box covers the entire area required, and finally release the left mouse button to determine the required drawing area 13 from the building design Figure 10

[0100] In other alternative embodiments, the drawing area 13 can also be determined from the building design Figure 10 by inputting a command line or a script. For example, the coordinates of the upper left corner and the lower right corner of the drawing area 13 are specified through the command line, and based on the coordinates of the upper left corner and the lower right corner, the drawing area is determined.

[0101] Based on the introduction of the method for determining the drawing area in the above embodiments, continue to refer to Figure 1 , the method for rapid modeling provided in this embodiment further includes:

[0102] S2. Generate shear walls according to the drawing area.

[0103] It can be understood that the drawing area gives the approximate range for automatically generating shear walls, and it is necessary to use the drawing area as a reference to generate shear walls that meet the structural specifications. For this, the following alternative embodiments of step S2 are provided in this embodiment:

[0104] S2-1. Determine the local walls located in the drawing area from the building design drawing.

[0105] For this, continue to refer to Figure 2 , a part of the boundary of the drawing area will intersect with the building walls in the entire building design drawing, thereby intercepting the local walls located in the drawing area.

[0106] S2-2. Generate shear walls that at least partially overlap with the local walls in the length direction according to the local walls.

[0107] For the above embodiments, it should be understood that if multiple local walls are intercepted in the drawing area, it means that multiple shear walls can be drawn simultaneously. Compared with the prior art where the structural designer draws shear walls one by one, through the above embodiments, multiple shear walls can be drawn at one time, significantly improving the work efficiency of the structural designer.

[0108] ​It should be noted that the lengths of shear walls are basically integer multiples of 50 mm. However, for the partial walls intercepted in the drawing area selected by the structural designers, their lengths may not be integer multiples of 50 mm. Therefore, when generating shear walls, the lengths need to be adjusted. In this regard, in this embodiment, after deducting the pre-reserved door and window openings in the building design from the partial walls remaining within the selected range, the baseline is further rounded, and the shear walls are generated based on the rounded baseline and the left and right widths of the partial walls. The baseline in the above implementation is used to clarify the drawing reference of the building walls. In the building design phase, the designer first uses the mouse tool to draw a baseline. Subsequently, the server will automatically generate the corresponding building walls according to the pre-set left width and right width.

[0109] In the specific implementation, for each partial wall, the server obtains the length of the partial wall; if the length of the partial wall does not satisfy an integer multiple relationship with the shortest length of the shear wall, the start and end positions of the partial wall are used as the initial start and end positions of the shear wall; at least one of the initial start and end positions is adjusted along the length direction to obtain the target start and end positions of the shear wall, so that the length of the shear wall satisfies an integer multiple relationship with the shortest length; the shear wall is generated according to the target start and end positions of the shear wall.

[0110] Of course, if the length of the partial wall satisfies an integer multiple relationship with the shortest length of the shear wall, the start position of the shear wall is directly used as the target start and end position of the shear wall. It should be noted that the start and end positions in the above embodiments include two positions, namely the start position and the end position in the length direction.

[0111] Exemplarily, assume that the length of the partial wall is 1129 mm. Considering that the length of the shear wall is usually an integer multiple of 50 mm (this is based on the standard practice in the construction industry), the length of the partial wall does not satisfy an integer multiple relationship. Therefore, the start and end positions of the partial wall can be used as the initial start and end positions of the shear wall, and it can be appropriately extended or shortened to obtain the target start and end positions of the shear wall. For example, if the length of the partial wall is 1129 mm, the length of the shear wall can be 1100 mm or 1150 mm, so as to satisfy an integer multiple relationship with 50 mm. In addition, when extending or shortening, only one of the start and end positions can be adjusted along the length direction, or both positions can be adjusted along the length direction simultaneously.

[0112] In the practical process, it is found that except for the case where the drawing area intercepts a complete wall, the partial walls intercepted in the drawing area will show Figure 3 and Figure 4 two situations. In Figure 3 , the partial wall 22 is aligned with one end of the complete wall 21 to which it belongs, that is, the partial wall 22 includes an end point of the complete wall 21. And in Figure 4In it, neither end of the partial wall 22 is aligned with the two ends of the complete wall 21. Given that the length of some inclined building walls is not an integer itself, if the drawing area intercepts the complete wall, it does not need to satisfy an integer multiple relationship with the shortest length. For Figure 3 and Figure 4 shown in the two cases, different adjustment strategies need to be adopted to obtain the target start and end positions of the shear wall. For this, this embodiment also provides the following implementation manners:

[0113] The server determines the complete wall to which the partial wall belongs; if one of the initial start and end positions is aligned with one end of the complete wall, the unaligned position in the initial start and end positions is adjusted along the length direction to obtain the target start and end positions of the shear wall; if the initial start and end positions are not aligned with any end of the complete wall, at least one of the initial start and end positions is adjusted along the length direction to obtain the target start and end positions of the shear wall.

[0114] Exemplarily, continuing with the partial wall 22 in Figure 3 as an example, since Figure 3 one end of the partial wall 22 in it is aligned with one end of the complete wall, the position of the other end of the partial wall 22 can be adjusted to the left or to the right to obtain the target start and end positions of the shear wall.

[0115] For Figure 4 shown partial wall 22, since this partial wall 22 is located in the middle of the complete wall 21 and is not aligned with any end of the complete wall 21, the positions of both ends of the partial wall 22 can be adjusted simultaneously along the length direction, that is, adjusted simultaneously along the left and right sides in the figure, to obtain the target start and end positions of the shear wall; or the position of one end of the partial wall 22 is adjusted along the length direction to obtain the target start and end positions of the shear wall.

[0116] For example, taking the adjustment simultaneously on both the left and right sides as an example. For Figure 4 the complete wall 21 in it, the end closest to both ends of the partial wall 22 is used as the anchor point. Then, the position of the end of the partial wall 22 close to the anchor point is adjusted along the length direction so that the distance from the anchor point to the proximal end of the partial wall 22 is an integer multiple of 50 mm, and the position of the end of the partial wall 22 far from the anchor point is adjusted along the length direction to obtain the target start and end positions of the shear wall, so that the length of the generated shear wall is also an integer multiple of 50 mm.

[0117] It should be noted that when automatically drawing the shear wall through the above embodiments, if the baseline of the drawn shear wall coincides with the baseline of the existing beam in the architectural design drawing, the overlapping part of the existing beam is automatically cut off. When it coincides with the baseline of the existing shear wall, the overlapping part of this shear wall is automatically cut off, and the remaining new shear wall is drawn.

[0118] In addition, to facilitate the operation of designers, a preview effect of shear walls is provided for designers during the process of selecting the drawing area. As an optional implementation manner, when dragging the mouse pointer 11, a preset texture or color can also be synchronously assigned to the intercepted partial wall, and the length of the shear wall generated based on the intercepted partial wall is displayed, so as to facilitate designers to preview. For example, Figure 2 the actual length of a partial wall currently intercepted in [the figure] is 1129 mm, and the length of the shear wall generated based on this partial wall should be 1150 mm. Therefore, 1150 mm is displayed at a position close to this partial wall, and a texture different from the original wall is assigned to the intercepted partial wall to represent the shear wall. It should be noted that Figure 2 the marked 1129 mm in [the figure] is only for the convenience of understanding and is not displayed during the actual drawing process, but only 1150 mm obtained based on 1129 mm is displayed.

[0119] Based on the existing partition walls, shear walls, roof beams, etc. in the architectural design drawing, the rapid modeling method provided in this embodiment can also automatically generate new roof beams in the architectural design drawing. In this regard, as Figure 5 shown in [the figure], on the basis of Figure 1 this, the method further includes:

[0120] S3, determining rectangular areas and non-rectangular areas from the architectural design drawing.

[0121] Among them, the rectangular area is the area corresponding to a rectangular room, and the non-rectangular area is the area corresponding to a non-rectangular room.

[0122] S4, dividing the non-rectangular area into rectangular sub-areas.

[0123] Among them, the rectangular sub-areas divided from the non-rectangular area include the largest rectangular area that the non-rectangular area can be divided into. This largest rectangular area is also called the main space. In this way, it is avoided that there are beams inside the main space, making the interior look more beautiful. In addition, in an optional implementation manner, the rectangular sub-areas divided from the non-rectangular area need to include not only the largest rectangular area that the non-rectangular area can be divided into, but also ensure that the number of divided rectangular sub-areas is the least. In this way, it is avoided to generate unnecessary roof beams subsequently.

[0124] As Figure 6 shown in [the figure], in order to meet the requirements of functional diversity, spatial innovation and aesthetics, rooms 23 with various shapes are designed in the architectural design drawing. Some of these rooms are rectangular, while some are non-rectangular. For the non-rectangular areas, they need to be divided into rectangular sub-areas.

[0125] Exemplarily, continue to take a non-rectangular area in the architectural design drawing shown in Figure 6 as an example. AsFigure 7 As shown, the server can first determine a rectangular sub-region s1 as the main space from the Figure 7 non-rectangular region shown, and then divide the entire non-rectangular region into local regions through this rectangular sub-region s1. Since these local regions are all rectangular, they are all regarded as rectangular sub-regions divided from the non-rectangular region, and are respectively represented as s2, s3, s4. In this way, a total of 4 rectangular sub-regions can be obtained, and there are 3 dividing lines 41 between the 4 rectangular sub-regions. It should be noted, however, that in the actual implementation process, not all of the divided local regions are rectangular, but some local regions are non-rectangular. At this time, these non-rectangular local regions can be regarded as new non-rectangular regions, and then the above implementation method can be used for further division until all are divided into rectangular sub-regions.

[0126] In this embodiment, the StraightSkeleton algorithm is adopted when solving the rectangular sub-region as the main space. In this regard, continue to take the Figure 7 non-rectangular region shown as an example. As Figure 8 shown, this algorithm can calculate an offset line 42 similar to a contour line according to the contour of the non-rectangular region, and can also calculate the highest ridge 43 (the ridge line or pole farthest from the contour). As Figure 9 shown, the server generates a rectangular sub-region s1 as the main space according to the distance from the highest ridge 43 to the contour of the non-rectangular region, and then several other rectangular sub-regions s2, s3, s4 can be divided through this rectangular sub-region s1. Given that the StraightSkeleton algorithm is a relatively mature algorithm in this field, the details of this algorithm will not be elaborated in this embodiment.

[0127] S5. Take the rectangular region and the rectangular sub-regions as the regions to be optimized respectively, and determine the dividing lines between the multiple regions to be optimized.

[0128] It should be noted that in some implementation manners, the multiple regions to be optimized may include all the rectangular regions and rectangular sub-regions in the architectural design drawing. In other implementable manners, the multiple regions to be optimized may include some of the rectangular regions and rectangular sub-regions in the architectural design drawing. For the above two implementation manners, those skilled in the art can make an adaptive selection according to needs when implementing this solution.

[0129] S6. Generate roof beams along the dividing lines.

[0130] Among them, the rectangular region is the region corresponding to the rectangular room. It should be understood that for larger regions, more structured and key beam frame designs are required around them, so these beams should be arranged first. And when determining the width of the beam, in order to ensure that the roof beam does not skew in the larger region, it is also necessary to give priority to considering the larger region. However, asFigure 7 As shown, rectangular sub-regions of different sizes share the same dividing line, which means there is a conflict in the roof beams determined by two rectangular sub-regions of different sizes.

[0131] In response to this, when generating roof beams along the dividing line in this embodiment, the server can sort multiple regions to be optimized in descending order of area, and the sorting result among the multiple regions to be optimized; according to this sorting result, generate roof beams for the target dividing line of each region to be optimized in sequence, where the target dividing line refers to the dividing line where no roof beam has been generated.

[0132] Exemplarily, continue to take the Figure 7 four rectangular sub-regions shown as an example. For the convenience of distinction, the four rectangular sub-regions are denoted as s1, s2, s3, s4, and the sorting result according to the size is s1, s2, s3, s4. Therefore, first determine the target dividing line that encloses the rectangular sub-region s1, and then, according to the size of the rectangular sub-region s1, determine the height required for the roof beam generated by each target dividing line. Then, judge whether the rectangular sub-region s2 has a target dividing line. Since the dividing line between the rectangular sub-region s2 and the rectangular sub-region s1 has already generated a roof beam, then continue to check whether the rectangular sub-region s3 has a target dividing line. And so on, until roof beams are generated for each dividing line 41. However, it should be noted that Figure 7 merely for the convenience of explanation, the provided example only includes rectangular sub-regions divided from non-rectangular regions, and in the actual implementation process, it is also necessary to sort in combination with the rectangular regions of the rectangular rooms.

[0133] In addition, when generating roof beams along the target dividing line, the server first deducts the part that coincides with the baselines of the existing shear walls and roof beams from the target dividing line to form a beam structure. Therefore, in a smaller room, many sides may be deducted to zero, so there is no need to additionally construct roof beams. Then, the server also sets the corresponding beam height according to the region type where the target dividing line is located (that is, whether it is inside or outside the floor area). Specifically, for those located inside the outer contour of the floor area, the first height is adopted, while for those located outside the outer contour of the floor area, the second height is adopted, where the first height and the second height are preset by the structural designer.

[0134] Furthermore, during the process of generating roof beams, the server also needs to consider the following factors to determine the width of the roof beam:

[0135] For each target dividing line, the server first needs to check whether there is a shear wall or beam with the same drawing direction intersecting it. If there is an existing shear wall or beam intersecting, the left and right widths of the intersecting wall or beam will be used to determine the left and right widths required for the beam generated along the target dividing line. Specifically, if the drawing direction is the same as that of the existing wall or beam, its left and right widths are directly used; if the drawing directions are opposite, the left and right widths of the existing shear wall or beam are exchanged, that is, the left width of the existing shear wall or beam is used as the right width of the beam along the target dividing line, and the right width of the existing shear wall or beam is used as the left width of the beam along the target dividing line. It should be understood here that the width of the beam is determined by the left width and the right width on both sides of the baseline, and the left and right are defined relative to the drawing direction of the baseline. Therefore, when the drawing directions are different, the left width and the right width need to be exchanged.

[0136] If there is no existing shear wall or beam intersecting, the server needs to determine the width of the beam along the beam according to the width of the upper building wall. If the wall width is greater than 150 mm, the server directly uses the left and right widths of the wall as the width parameters of the beam along the target dividing line. Similarly to the above embodiment, if the directions are the same, the left and right widths of the upper building wall are directly taken; if the directions are opposite, the left and right widths of the upper building wall are exchanged.

[0137] If the wall width is not greater than 150 mm, the server also needs to further detect the structural elevation of the room and whether there is a hollow situation. If the structural elevation of the room is different from the default value, or there is a hollow phenomenon (the specific judgment basis is to view the building configuration of the currently processed floor and whether there is a wall structure connected to the common partition wall on the upper layer), a beam is constructed on this side. The width of the beam is set to 150 mm to ensure that the beam does not exceed the room boundary and avoid protruding into the room.

[0138] For other situations, no beam needs to be constructed on this side.

[0139] For the beams automatically generated through the above embodiments, the server further optimizes them to delete unnecessary beams. Specifically, the server determines all the floor slabs with short-span not greater than 1000 mm, and then analyzes each side of the floor slab. If there is no building partition wall on a certain side, or the height of the partition wall is less than the height threshold (for example, taking 500 mm as the height threshold) and it is not on the outer contour, the beam on this side is deleted.

[0140] Exemplarily, referring to Figure 10 the first partial area 31 of the shown architectural design drawing, two first beams 35A and two other second beams 35B are shown in the first partial area 31. Among them, the short-span corresponding to the two first beams 35A is less than the set threshold, and there is no partition wall above these two first beams 35A. Therefore, in Figure 11In the optimized architectural design drawing shown, these two first roof beams 35A are deleted; while there are partition walls above the other two second roof beams 35B, so they are retained.

[0141] In addition, the continuous beams formed by the shear walls are not considered in the above embodiments. In this regard, the method for rapid modeling provided in this embodiment can also automatically generate continuous beams at appropriate positions in the architectural design drawing. Therefore, this embodiment also provides an optional implementation manner to achieve this function:

[0142] For each shear wall, if the server determines the optimization ends from both ends of the shear wall, then it is determined whether the distance between the optimization end and the adjacent wall is less than the span threshold, where there is no roof beam or other shear wall collinear with the shear wall at the optimization end, and the adjacent wall refers to the wall closest to the optimization end along the length direction of the shear wall.

[0143] If it is less than the span threshold, the server generates a roof beam that connects with the shear wall and the adjacent wall along the length direction of the optimization end.

[0144] In the specific implementation manner, the server first finds all the shear walls inside the outer contour, and then, for each shear wall, checks whether there are roof beams connected and collinear with it at both ends of the shear wall; if so, no optimization is required. If none of the roof beams at one end of the shear wall are connected and collinear with it, the server takes this end of the shear wall as the optimization end, and calculates whether the distance between the optimization end and the adjacent wall is less than the span threshold. If it is less than the span threshold, a roof beam that connects with the shear wall and the adjacent wall along the length direction of the optimization end is generated. In this embodiment, the span threshold is set to 1600 mm.

[0145] Exemplarily, refer to Figure 12 the second partial area 32 of the architectural design drawing shown. For the shear wall 33 in the second partial area 32, there is no collinear roof beam or other shear wall at the right end of the shear wall 33, so the right end of the shear wall 33 is taken as the optimization end; and the distance between the optimization end and the adjacent wall 34 is also less than the span threshold. Therefore, as Figure 13 shown, a third roof beam 35C spanning between the optimization end of the shear wall 33 and the adjacent wall 34 can be generated. Figure 13 In order to facilitate distinction, the shear wall 33 and the generated third roof beam 35C are marked with different patterns respectively.

[0146] Based on the introduction of shear walls and roof beams in the above embodiments, it should also be understood that although a floor slab can be formed after the shear walls and roof beams are enclosed, it is not necessary to set a floor slab in every enclosed area. Therefore, in the structural design, it is also necessary to determine whether to set a floor slab according to the actual needs of the building. Specifically, the server will find the rooms located above, determine whether to hollow out, whether to lower the slab and the specific height of the slab lowering according to the room types to be borne, and obtain the load values for subsequent structural calculations.

[0147] Exemplarily, Figure 12 After the building design drawing shown is optimized by the above embodiments, the shear walls and roof beams enclose a floor slab 36 as shown in Figure 14 . However, Figure 14 In the positions such as the staircase 39, elevator shaft 38, air duct 40, etc. in, the corresponding rooms are required to be hollowed out, so no floor slab needs to be set in these positions. In addition, Figure 14 In the toilet 37 in, the corresponding room is required to lower the slab to achieve same-floor drainage. Therefore, it is necessary to lower the floor slab elevation for matching. In this regard, this embodiment also provides a room table of the building, which describes the information of each room regarding live load, hollowing out, floor slab elevation, etc., and briefly explains the hollowing out and slab lowering to seamlessly connect with the subsequent design link of the floor slab thickness. It should be noted, however, Figure 14 The floor slab 36 in is not limited to the marked part, but only part of the floor slabs are marked for the sake of the beauty of the drawings.

[0148] When determining the floor slab thickness, it is necessary to rely on the span of the floor slab. However, it is found in the practical process that although most of the floor slab contours are rectangular, there are also a small number of non-rectangular ones. For a rectangular floor slab, the long-span and short-span slab spans can be determined according to the length and width of the rectangle. For the non-rectangular floor slabs in the building design drawing, the server obtains the circumscribed rectangle tightly wrapped around the contour of the non-rectangular floor slab; and determines the floor slab thickness of the non-rectangular floor slab according to the length-width ratio of the circumscribed rectangle.

[0149] Exemplarily, as Figure 15 shown, for the contour 51 of the non-rectangular floor slab, a circumscribed rectangle 52 tightly wrapped around the contour 51 of the non-rectangular floor slab is constructed, and the length-width ratio of the circumscribed rectangle 52 is matched with a preset floor slab thickness table to obtain the floor slab thickness of the non-rectangular floor slab. It can be understood that the floor slab thickness table records the mapping relationship between the length-width ratio and the floor slab thickness. For example, the floor slab thickness table can record the following content:

[0150]

[0151] In addition, for the circumscribed rectangle 52 tightly wrapped around the contour 51 of the non-rectangular floor slab. Continue to refer to Figure 15In some embodiments, the outline 51 of the non-rectangular floor slab may be located within a circumscribed rectangle 52. In this case, the two outermost sides of the circumscribed rectangle, located on the same side of the non-rectangular floor slab, are parallel to each other and separated by a predetermined distance. Of course, if the predetermined distance is zero, the circumscribed rectangle 52 partially overlaps with the outline 51 of the non-rectangular floor slab.

[0152] The above embodiment introduces a quick construction method for shear walls, beams, and floor slabs.
