Description

Technical Field

[0001] The present invention relates to the technical field of building structure design, and particularly relates to a method, device and related components for intelligently generating staircase detail drawings. Background Art

[0002] In the field of architectural design, the staircase detail drawings in the construction drawing design stage, as an important part of the construction project drawings, undertake the dual functions of connecting the specification standards and technical implementation. According to the requirements of the current construction project drawing specification, after the building plan is determined, the architectural designer needs to accurately draw staircase detail drawings including parameters such as step size, clear height of the flight, and landing width, which not only meet the technical indicators of mandatory clauses such as the Unified Standard for Civil Building Design, but also provide a reliable load calculation basis for the structural specialty, and at the same time guide the formwork support and steel bar binding operations at the construction site. The traditional design process commonly used in the current industry includes four core links: firstly, establishing a floor elevation system and an axis positioning network based on the finalized building plan; secondly, manually checking relevant specification articles to repeatedly verify parameters such as flight slope, step height, and landing size; then using CAD software to manually draw the staircase outline layer by layer, and in this process, multiple rounds of adjustments are required for the number of steps and the construction nodes at the turning of the flight; finally, it is also necessary to manually calculate whether the clear height of the flight meets the requirement of the headroom space through the geometric projection method and complete the in-depth dimension marking of the sectional view. This working mode has significant efficiency bottlenecks and quality risks: According to statistics, the workload of drawing staircase detail drawings accounts for about 15%-20% of the total workload of construction drawings. Designers need to invest a lot of time in parameter checking and graphic correction. Especially in high-rise buildings, the efficiency loss rate due to repeated drawing of floors can reach more than 40%; at the same time, manual calculation is prone to design defects such as errors in the number of steps and insufficient headroom height, and the design change rate caused by later drawing modification is as high as 12.7%. This manual operation mode that highly depends on the experience of designers has become the key pain point restricting the improvement of construction drawing design efficiency.

[0039] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0040] It should be further understood that the term " / and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] Please refer to Figure 1 , this embodiment provides an intelligent generating method for staircase detail drawings, including:

[0042] S101: Obtain the basic project information and floor information input by the user;

[0043] Specifically, the basic project information includes staircase attributes, staircase hall dimensions, beam height, and default surface layer thickness, and the floor information includes the roof, machine room floor, above-ground floors, underground floors, and the floor height of each floor.

[0044] Among them, the staircase attributes include: residential public staircases, indoor staircases in residential units, dormitory staircases in primary schools, other dormitory staircases, staircases in buildings for the elderly, staircases in buildings for the elderly, staircases in nurseries and kindergartens, and staircases in primary schools; staircases in buildings with dense population and busy vertical traffic, and in large and medium-sized schools; other building staircases, staircases in the core tube of super high-rise buildings, and maintenance and internal service staircases.

[0045] Furthermore, the staircase hall dimensions are the internal net dimensions of the staircase hall. The beam height and the default surface layer thickness are initially given certain values, and the user can modify this data by themselves.

[0046] In some embodiments, the basic project information further includes: input platform thickness and calculation parameters for the thickness of the flight slab. The calculation parameters for the platform thickness and the flight slab thickness can provide a reliable data basis for the structural design of the project, ensuring the safety and rationality of the entire project.

[0047] Then, the user can set the positions and quantities of the roof, machine room floor, above-ground floors, and underground floors according to the actual situation (as Figure 2 shown), and at the same time set the floor height of each floor, thereby generating a platform information table for the entire floor.

[0048] In this embodiment, Figure 2 in the interface, above-ground floors are defaultly present. If only underground floors need to be drawn, the above-ground floors can be cancelled by clicking on the checkbox.

[0049] Among them, there are five types of addable types for above-ground floors: ordinary floors, standard floors, refuge floors, machine room floors, and roof floors; when selecting a standard floor, multiple floors can be input at one time.

[0050] Furthermore, pressing the "+" sign can add above-ground and underground floors; for above-ground floors, floors are added upwards, and for underground floors, floors are added downwards. Pressing the "-" sign deletes the corresponding above-ground and above-ground floors.

[0051] Furthermore, the ground elevation is defaultly ±0.00 and can be modified.

[0052] Furthermore, underground floors are defaultly not present. If underground floors need to be drawn, the underground floor option can be shown by checking the checkbox.

[0053] Furthermore, when there are above-ground floors, the top elevation of the underground staircase roof is linked to the elevation of the first floor. When there are no above-ground floors, the top elevation of the underground staircase roof can be modified independently.

[0054] Further, if you need to modify the previous information, click the previous step to operate.

[0055] In one example, please refer to Figure 3 , there are 3 above-ground floors, namely 1F (the ground floor), 2F, and 3F. At the same time, there is an RF roof floor on the 3F, and there are 4 underground floors, namely B1F, B2F, B3F, and B4F. Among them, the elevation of the 1F ground floor is set to ±0, and the floor height between the 1F ground floor and the 2F is set to 6m. Therefore, the elevation of the 2F is 6m (i.e., the elevation of the 1F ground floor 0 + the floor height 6), and the floor height between the 2F and the 3F is set to 6m. So, the elevation of the 3F is 12m (the elevation of the 2F 6 + the floor height 6). Similarly, the elevations of other floors can also be calculated accordingly.

[0056] It should be noted that when setting the roof, machine room floor, above-ground floors, and underground floors, several of them can be selectively set. For example, only the roof and above-ground floors can be set.

[0057] Further, please refer to Figure 4 , after this embodiment obtains all the floor information and calculates the elevations of each floor, it will generate a corresponding information sketch. The elevation values of each floor will be clearly marked in the information sketch in the floor order to ensure the accuracy of the data.

[0058] S102: Generate a platform information table according to the floor information and feedback the platform information table to the user;

[0059] S103: Obtain the entrance and exit platform information checked by the user in the platform information table;

[0060] Among them, the entrance and exit platforms include: the left entrance and exit platform and the right entrance and exit platform. Checking the entrance and exit platforms is only related to whether the stair platform is set, and has nothing to do with whether the door is opened.

[0061] After the user checks the entrance and exit platform information, the elevations of the corresponding floors of each entrance and exit platform will be set as the elevations of each entrance and exit platform. Among them, the user can modify the elevations of each entrance and exit platform according to the actual situation. For example, Figure 5 the B2F in

[0062] has been modified. Thus, the system will turn it red to remind the user that the data has been modified so that the user can confirm whether the modified data is incorrect.

[0063] It should be noted that the elevations of the left entrance and exit platform and the right entrance and exit platform are usually the same. There is usually 1 height difference between the two platforms, occasionally 2 height differences, and rarely 3 or 4 height differences.

[0064] S104: Calculate the intermediate platform and flight information based on the basic project information and the entrance and exit platform information;

[0065] Specifically, calculating the intermediate platform (also known as the rest platform) and flight information based on the basic project information and the entrance and exit platform information includes: generating the number of stair groups on this floor according to the number of entrances and exits on this floor and the upper floor; then referring to the stair attribute table according to the stair attributes to obtain the maximum flight height of each floor; obtaining the elevation of each entrance and exit platform according to the entrance and exit platform information; calculating the height difference between each entrance and exit platform and the previous entrance and exit platform according to the elevation of each entrance and exit platform; calculating the number of flights on the corresponding floor according to the height difference between each entrance and exit platform and the maximum flight height; calculating the number of intermediate platforms on the corresponding floor according to the number of flights on the corresponding floor; and then calculating the elevation of each intermediate platform according to the elevation, height difference, and number of flights of the entrance and exit platform on the floor corresponding to each intermediate platform.

[0066] This calculation process reduces the workload and time cost of manual calculation. The designer only needs to input the basic project information and the entrance and exit platform information, and the system can automatically complete the calculation of the intermediate platform and flight information, greatly improving the design efficiency.

[0067] In this embodiment, generating the number of stair groups on this floor according to the number of entrances and exits on this floor and the upper floor includes:

[0068] If the number of entrances and exits on this floor is 2 and the number of entrances and exits on the upper floor is 2, then generate two stair groups on this floor; for example, Figure 6 The number of entrances and exits on the 2F is 2, and the number of entrances and exits on its upper floor, the 3F, is 2, then generate two stair groups on the 2F.

[0069] If the number of entrances and exits on this floor is 1 and the number of entrances and exits on the upper floor is 2, then generate one stair group on this floor;

[0070] If the number of entrances and exits on this floor is 2 and the number of entrances and exits on the upper floor is 1, then generate one stair group on this floor;

[0071] If the number of entrances and exits on this floor is 1 and the number of entrances and exits on the upper floor is 1, then generate one stair group on this floor.

[0072] In this embodiment, the maximum flight height of each floor is obtained by referring to the stair attribute table according to the stair attributes. The stair attribute table is shown in Table 1.

[0073] Table 1

[0074]

[0075] The maximum flight height in Table 1 is calculated from 18 times the maximum tread width. For example, for the public stairs in a residence, the maximum tread width is 0.175, and its maximum flight height is 0.175 × 18 = 3.15.

[0076] It should be noted that the relevant specification sources for the stair attribute table are mainly based on the "General Code for Civil Buildings GB55031-2022" and the "Unified Standard for Design of Civil Buildings GB50352-2019".

[0077] In this embodiment, the height difference between each entrance and exit platform and the previous entrance and exit platform calculated according to the elevation of each entrance and exit platform includes: subtracting the elevation of the current entrance and exit platform from the elevation of the previous entrance and exit platform to obtain the height difference between each entrance and exit platform and the previous entrance and exit platform. For example, Figure 6 the elevation of the entrance and exit platform on the 3F in [example] is 12, and the elevation of its previous entrance and exit platform is 17.95. Therefore, the height difference on the 3F is 17.95 - 12 = 5.95. The elevation of the entrance and exit platform on the B2F is -14.57, and the elevation of its previous entrance and exit platform on the B1F is -8.4. Therefore, the height difference on the B2F is -8.4 - (-14.57) = 6.17.

[0078] In this embodiment, the number of flights corresponding to each floor calculated according to the height difference between each entrance and exit platform and the maximum flight height is specifically the height difference between each entrance and exit platform divided by the maximum flight height to obtain the number of flights corresponding to each floor. If it cannot be divided exactly, round up and add 1. For example, Figure 6 the height difference on the B1F in [example] is 8.4, and the maximum flight height is 3.15. The number of flights is 8.4 / 3.15 = 2.6, rounded up to 2, and adding 1 is 3. Similarly, the number of flights for all floors is calculated.

[0079] Then calculate the number of intermediate platforms. Specifically, the number of intermediate platforms = the number of flights on this floor - 1.

[0080] Then calculate the elevation of the intermediate platform. The elevation of the intermediate platform = the elevation of the entrance and exit platform on the corresponding floor + the height difference / the number of flights on this floor. For example, the elevation of the intermediate platform on the 3F = 12 + 5.95 / 2 = 14.975. The elevation of the intermediate platform on the B1F = -8.4 + 8.4 / 3 = -5.6. Since there are two intermediate platforms on it, the elevation of its other intermediate platform is -5.6 + 8.4 / 3 = -2.8.

[0081] S105: Integrate the intermediate platform and flight information and the entrance and exit platform information to obtain complete platform information;

[0082] Please refer to Figure 7, integrate the intermediate platform and flight information with the entrance and exit platform information to obtain the complete platform information. The complete platform information includes the information of each entrance and exit platform and the information of the intermediate platforms between each entrance and exit platform.

[0083] Furthermore, after integrating the intermediate platform and flight information with the entrance and exit platform information to obtain the complete platform information, it includes:

[0084] Number each entrance and exit platform and intermediate platform according to the complete platform information in a top-down and left-right rotation numbering manner.

[0085] Among them, the two scissors ladders in this embodiment are distinguished by the numbers AP and BP. All platforms with the same number belong to the same ladder.

[0086] In this embodiment, the increased number of intermediate platforms is: the number of platforms increased upward from the entrance and exit platform, that is, the number of rows increased upward in the table.

[0087] The number of ladder groups on this floor is: whether the intermediate platform is increased on both sides (i.e., the number of ladder groups is 2) or on one side (i.e., the number of ladder groups is 1). Increasing on both sides means adding an intermediate platform on each of the left and right sides; increasing on one side means adding an intermediate platform on the opposite side of the adjacent single platform.

[0088] If both the upper entrance and exit platform and the lower entrance and exit platform are on one side and on the opposite side, it depends on the situation. Situation 1: The platform in the flight requires sufficient staircase length support; Situation 2: Add two intermediate platforms, and increase two intermediate platforms downward from the upper platform at a height difference of 1400 mm.

[0089] S106: Perform height difference verification according to the complete platform information and make corresponding adjustments according to the verification results to obtain the staircase information;

[0090] Specifically, performing height difference verification on the complete platform information and making corresponding adjustments according to the verification results to obtain the staircase information includes: calculating the height difference between adjacent upper and lower platforms on the same side according to the complete platform information; determining whether the height difference between adjacent upper and lower platforms on the same side is greater than or equal to the predetermined height difference; if the height difference between adjacent upper and lower platforms on the same side is less than the predetermined height difference, then adjust the elevation of the lower platform among the adjacent upper and lower platforms on the same side, and recalculate the height difference between adjacent upper and lower platforms on the same side after the adjustment.

[0091] For example, please refer to Figure 8, the elevation of the landing AP13 is -16.7, and the elevation of the previous landing BP10 on the same side is -14.57. Therefore, the elevation difference of AP13 is 2.13, while the predetermined elevation difference is 2.73. So, the elevation difference of AP13 is less than the predetermined elevation difference. Then, it is necessary to adjust the elevation of the landing AP13. The elevation of the landing AP13 is adjusted to -17.4, and the calculated elevation difference of AP13 is 2.83, which is greater than the predetermined elevation difference of 2.73. At this time, the elevation of the landing AP13 is -17.4.

[0092] It should be noted that when calculating the elevation of the landing, rounding is required. And when the elevation of the platform in this embodiment needs to be adjusted, it is usually the elevation of the previous platform minus 2.8, and then rounding. For example, -14.57 minus 2.8 for BP10, the value is -17.37, and the rounded value is -17.4.

[0093] Among them, the reason for the predetermined elevation difference of 2.73m is as follows: The height of the first - level step is taken according to the staircase attributes, and the maximum can be considered as 180mm. The requirement for the clear height of the platform is: 2100mm, and it is necessary to stagger 300mm from the leading edge line of the lowest - level step. The height of the staircase beam is: 450mm, including the surface layer, and can be adjusted according to parameter settings. The sum of the height of the first - level step, the requirement for the clear height of the platform, and the height of the staircase beam is 2730mm. If calculated according to a single - ladder and half - platform, it is 1365mm.

[0094] In this embodiment, even if there are marked - red data (as Figure 9 shown), a section can still be generated, and a cloud - line marking will be added later.

[0095] Furthermore, according to the complete platform information, the elevation difference is verified and corresponding adjustments are made according to the verification results. The staircase information obtained also includes:

[0096] Calculating the elevation difference between two adjacent platforms based on the platform information of each entrance and exit and the elevation of the intermediate platform;

[0097] Calculating the minimum number of staircase steps that meet the specifications and the corresponding step height based on the elevation difference between two adjacent platforms.

[0098] After calculating the elevation difference between two platforms, the minimum number of staircase steps, and the corresponding step height, then it is necessary to conduct a clear - height verification.

[0099] The clear - height verification includes: verifying that the clear height of the platform ≥ 2100 and verifying that the clear height of the staircase section ≥ 2200. If the clear - height verification is passed, the complete staircase information can be formed. If the clear - height verification is not passed, parameters need to be adjusted to pass the clear - height verification.

[0100] At the same time, this embodiment also needs to perform other verifications, for example, it needs to pass the verification of "General Code for Civil Buildings GB55031-2022", "Uniform Standard for Design of Civil Buildings GB50352-2019" and "General Code for Fire Protection of Buildings GB55037-2022". Specifically, according to "General Code for Civil Buildings GB55031-2022", the step height and width of each section of stairs should be consistent, the height difference between adjacent sections of stairs should not be greater than 0.01m, and anti-slip measures should be taken on the step surface.

[0101] S107: Generate a detailed staircase drawing according to the staircase information.

[0102] See also Figures 10 - 12 Before generating the staircase detailed drawing, this embodiment needs to modify and confirm the various values ​​of the plane figure and the various values ​​required by the staircase figure.

[0103] Table 2

[0104]

[0105] Table 3

[0106]

[0107]

[0108] In this embodiment, after modifying and confirming the values ​​of the plane figure and the values ​​required by the staircase figure, the corresponding railing can be generated. Specifically, the height of the indoor stair handrail should not be less than 0.9m from the front edge of the step. When the length of the horizontal railing or balustrade of the stairs is greater than 0.5m, its height should not be less than 1.05m.

[0109] Next, this embodiment can generate a detailed staircase drawing according to modifying and confirming various values ​​of the plane drawing and various values ​​required by the staircase drawing, and the staircase information.

[0110] The staircase detail drawing includes the staircase section drawing and the staircase plan drawing. When the staircase section drawing and the staircase plan drawing are generated, the corresponding data information table will be generated.

[0111] In this embodiment, when generating drawings, if the calculated data of a certain layer cannot meet the specification requirements, the drawing will be avoided and changed into graphics when generating the drawing sample, and only the image of the entrance and exit platform will be generated. Among them, the standard layer image generation will be realized by cutting, and only a single floor image will be drawn.

[0112] In this embodiment, special types of stairs such as spiral staircases and curved staircases are also automatically calculated and generated.

[0113] For spiral staircases, it is necessary to accurately calculate the spiral radius, the radian of the steps, and the difference in the step sizes between the inner and outer sides. Specifically, in addition to obtaining information such as the size of the staircase room, the storey height, the beam height, and the default surface layer thickness, it is also necessary to collect key parameters of the spiral staircase, such as the position of the spiral central axis (which can be determined by specifying coordinate points on the CAD drawing), the spiral radius, the rotation direction (clockwise or counterclockwise), the starting angle, and the ending angle, etc.

[0114] Furthermore, based on the position of the spiral central axis input by the user and the boundary information of the staircase, accurately calculate the spiral radius. During the calculation process, the inner and outer boundaries of the staircase should be taken into account to ensure accurate values of the inner and outer spiral radii.

[0115] Then, according to the total rotation angle of the spiral staircase and the number of steps, calculate the radian of each step. The formula is: Radian of a single step = Total rotation angle / Number of steps. At the same time, the influence of the width and thickness of the steps on the radian should be considered for appropriate correction.

[0116] Since the radii of the inner and outer sides of the spiral staircase are different, the step sizes will also vary. Then, according to the inner and outer spiral radii and the radian of the steps, calculate the lengths and widths of the inner and outer steps. Generally, the length of the outer step will be greater than that of the inner step. The calculation formulas are as follows:

[0117] Length of the inner step = 2×π×Inner spiral radius×Radian of a single step / 360°;

[0118] Length of the outer step = 2×π×Outer spiral radius×Radian of a single step / 360°.

[0119] Then, based on the calculated information such as the spiral radius, the radian of the steps, and the inner and outer step sizes, generate a 3D model of the spiral staircase in the CAD operation interface. The model should be able to clearly display the spiral shape of the staircase, the details of the steps, and the spatial relationship with the surrounding environment.

[0120] On the basis of generating the 3D model, further draw the 2D detailed drawings of the spiral staircase, including sectional views, floor plans, elevation views, etc. During the drawing process, accurately mark the dimensions and angles of each part to ensure that the construction personnel can construct accurately according to the drawings.

[0121] In this embodiment, for curved staircases, the influence of the arc curvature and the center position of the circle on the step sizes and the platform layout should be considered to meet the diverse architectural design requirements.

[0122] Specifically, collect information such as the arc curvature of the curved staircase (which can be represented by the radius or the radius of curvature), the center position of the circle (also determined by the coordinate points on the CAD drawing), the starting and ending positions of the arc, and the direction of the staircase.

[0123] Then, based on the radius of curvature and the position of the center of the arc, as well as the width of the staircase, calculate the dimensions of each step. On an arc-shaped staircase, the lengths of the inner and outer sides of the steps change as the arc bends. The arc can be divided into several small segments, each of which is approximately regarded as a straight line, and then the dimensions of the steps corresponding to each small segment are calculated according to the geometric relationship.

[0124] Next, consider the shape of the arc and the position of the center of the circle to determine the position and dimensions of the landing. The setting of the landing should meet the requirements of personnel evacuation and use, and at the same time be coordinated with the trend of the arc. The specific layout of the landing can be determined by calculating the intersection position of the arc and the landing, as well as the length and width of the landing.

[0125] Then, using the information such as the calculated arc curvature, center position, step dimensions, and landing layout, generate a three-dimensional model of the arc-shaped staircase. The model should be able to truly reflect the bending effect of the arc and the overall shape of the staircase.

[0126] Next, based on the three-dimensional model, draw the two-dimensional detailed drawings of the arc-shaped staircase, which also include sectional views, plan views, elevation views, etc. On the drawings, the radius of the arc, the position of the center of the circle, the step dimensions, and the relevant information of the landing should be marked in detail so that the construction personnel can understand and construct.

[0127] In this embodiment, by summarizing the drawing methods and logics of the detailed staircase drawings in the conventional business process of architectural construction drawings, it maximally meets the usage habits of designers and is built into the CAD workflow, making it more convenient to use. At the same time, the user only needs to input simple parameters, and other work is automatically completed by the computer background, which can quickly generate the staircase detailed drawings, greatly improving the work efficiency. In addition, after the parameter input, the system automatically checks and calculates the clear height of the staircase, the height difference between adjacent steps, etc. according to the specification requirements to confirm whether they meet the specification requirements, reducing the error rate.
