Description

Technical Field

[0001] This invention relates to the field of drawing review technology, and in particular to a method, system and equipment for reviewing building staircases based on construction drawings. Background Technology

[0002] With the rapid development of science and technology, people have increasingly higher requirements for housing conditions, which has also made construction quality problems in the construction industry more and more prominent. The essence of construction quality problems lies in the design of construction drawings, therefore, drawing review is a very important step.

[0003] Currently, the architectural design industry commonly uses CAD software to create drawings. Once completed, these drawings typically require manual review by experienced engineers or specialized reviewers to determine if they violate national building standards. This results in significant variations in the review process due to individual project experience, knowledge base, and years of experience. The large amount of manual work also makes it difficult to establish a complete review process, which can easily lead to excessively long review times and even affect the building's lifecycle. Summary of the Invention

[0004] Based on this, the purpose of this invention is to propose a method, system, and equipment for reviewing building staircases based on construction drawings, so as to solve the problem of excessively long review cycles caused by the traditional method of manually reviewing drawings.

[0005] According to the present invention, a method for reviewing building staircases based on construction drawings is provided, the method comprising:

[0006] Retrieve the target floor plan and locate the area marked with the name of the stair component in the target floor plan based on the input name of the stair component;

[0007] The area marked with the names of the stair components is selected to obtain the first target area;

[0008] Locate the plan view of the stair component in the first target area and review it to obtain the first review result of the stair component;

[0009] Retrieve the target cross-sectional view and locate the position of the name label of the stair component in the target cross-sectional view according to the input name of the stair component;

[0010] The area marked with the names of the stair components is selected to obtain the second target area;

[0011] The cross-sectional structure of the stair component is located in the second target area and reviewed to obtain a second review result of the stair component.

[0012] In summary, based on the above-described method for reviewing building staircases using construction drawings, the following steps are taken: First, the target floor plan is retrieved, and the area marked with the name of the staircase component is located on the target floor plan according to the input name of the staircase component. This area is then selected to obtain a first target area. The floor plan structure of the staircase component is found within the first target area and reviewed to obtain a first review result. Next, the target sectional view is retrieved, and the location marked with the name of the staircase component is located on the target sectional view according to the input name of the staircase component. This area is then selected to obtain a second target area. The sectional view structure of the staircase component is found within the second target area and reviewed to obtain a second review result. This invention replaces the traditional manual review method for staircase components by comprehensively and automatically reviewing both the floor plan and sectional view to obtain the review result, and solves the problem of excessively long review cycles.

[0013] Further, the step of locating the plan view structure of the stair component in the first target area and reviewing it to obtain a first review result of the stair component includes:

[0014] Locate the planar stair flight group of the stair components in the first target area and examine the structure of the planar stair flight group;

[0015] If the structural review of the planar staircase group meets the requirements, the net width of the planar staircase group is obtained by analyzing and calculating based on the structure of the planar staircase group and the information of the contents of the staircase floor.

[0016] Locate the stair platforms on both sides of the planar stair section group and determine whether the net width of the stair platforms on both sides of the planar stair section group meets the requirements based on the net width of the planar stair section group.

[0017] Further, the step of locating planar stair flight groups of stair components in the first target area and examining the structure of the planar stair flight groups includes:

[0018] In the first target region, find a group of line segments that contain line segments of the same length, the same slope, and the same spacing.

[0019] If a group of line segments containing line segments of the same length, slope, and spacing is found, then the line segments of the same length, slope, and spacing are defined as planar trapezoidal segments, and the group of line segments containing line segments of the same length, slope, and spacing is defined as a group of planar trapezoidal segments.

[0020] Determine whether the length of each planar stair segment in the planar stair segment group is within a first preset length range and whether the spacing between each pair of adjacent planar stair segments is within a preset spacing range.

[0021] Further, the step of analyzing and calculating the net width of the planar stair segment of the planar stair segment group based on the structure of the planar stair segment group and the information of the contents of the stair floor includes:

[0022] Determine whether one or both ends of the planar stair segment in the planar stair segment group intersect with the contents of the staircase floor.

[0023] If both ends of the planar stair segment in the planar stair segment group intersect with the contents of the staircase floor, then find the midpoint of any planar stair segment and obtain the nearest intersection point on both sides of the midpoint, and set it as the target intersection point;

[0024] The distance between the two target intersection points is calculated to obtain the net width of the planar stair segment of the planar stair segment group.

[0025] Further, the step of locating the stair landings on both sides of the planar stair flight group and determining whether the clear width of the stair landings on both sides of the planar stair flight group meets the requirements based on the clear width of the planar stair flight group includes:

[0026] Obtain the outer rectangular outline of the planar stair segment group and construct the first circumscribed rectangle of the planar stair segment group with a first outward expansion distance, wherein the first outward expansion distance is less than the net width of the planar stair segment of the planar stair segment group;

[0027] Determine whether there exists a spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar stair segment group;

[0028] If there is no spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar stair segment of the planar stair segment group, then determine whether the net width of the planar stair segment of the planar stair segment group is greater than the preset net width.

[0029] If the net width of the planar stair segment of the planar stair segment group is greater than the preset net width, then the outer rectangular outline of the planar stair segment group is expanded outward along the direction perpendicular to the planar stair segment of the planar stair segment group to obtain the first expanded area;

[0030] Determine whether there are wall columns with a length greater than a preset length or doors with an opening direction perpendicular to the planar stair section group within the first outer expansion area;

[0031] If there are no wall columns with a length greater than the preset length or doors with an opening direction perpendicular to the planar stair section group within the first outer expansion area, then it is determined that the net width of the stair platforms on both sides of the planar stair section group meets the requirements.

[0032] Further, the step of finding and reviewing the cross-sectional structure of the stair component in the second target area to obtain a second review result of the stair component includes:

[0033] Locate the cross-sectional stair section group of the stair components in the second target area and examine the structure of the cross-sectional stair section group;

[0034] If the structural review of the section staircase group meets the requirements, the structure of the section staircase group is analyzed to find the structure of the upper and lower staircase platforms connected to the section staircase group.

[0035] The structure of the upper and lower stair platforms of two adjacent cross-sectional stair groups is analyzed and calculated to obtain the distance between two adjacent directly opposite stair platforms, and the distance between two adjacent directly opposite stair platforms is used to determine whether the height requirement for human passage is met between the two adjacent cross-sectional stair groups.

[0036] Furthermore, the step of locating the cross-sectional stair segment group of the stair components in the second target area and examining the structure of the cross-sectional stair segment group includes:

[0037] In the second target area, find a group of line segments that contains a preset number or more consecutive and perpendicular line segments.

[0038] If a line segment group containing a preset number or more horizontal and vertical line segments that are connected end to end and perpendicular to each other is found, then the horizontal line segments in the horizontal and vertical line segments are set as cross-sectional horizontal trapezoidal segments, the vertical line segments in the horizontal and vertical line segments are set as cross-sectional vertical trapezoidal segments, and the line segment group containing a preset number or more horizontal and vertical line segments that are connected end to end and perpendicular to each other is set as a cross-sectional trapezoidal segment group.

[0039] Determine whether the lengths of the horizontal and vertical sections in the section segment group meet the requirements.

[0040] In another aspect, the present invention provides a system for reviewing building staircases based on construction drawings, comprising:

[0041] The first search module is used to retrieve the target floor plan and locate the area marked with the name of the stair component in the target floor plan based on the input name of the stair component.

[0042] First selection module: used to select the area marked with the name of the stair component to obtain the first target area;

[0043] First acquisition module: used to find the plan view structure of the stair component in the first target area and review it to obtain the first review result of the stair component;

[0044] The second search module is used to retrieve the target cross-sectional view and locate the position of the name label of the stair component in the target cross-sectional view according to the input name of the stair component;

[0045] The second selection module is used to select the area marked with the name of the stair component to obtain the second target area;

[0046] The second acquisition module is used to find the cross-sectional structure of the stair component in the second target area and review it to obtain the second review result of the stair component.

[0054] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] Example 1

[0058] Please see Figure 1 This invention proposes a method for reviewing building staircases based on construction drawings, the method comprising steps S101 to S106:

[0059] S101, retrieve the target floor plan and locate the area marked with the name of the stair component in the target floor plan according to the input name of the stair component.

[0060] It should be noted that before reviewing construction drawings, the drawings (such as CAD drawings) need to be analyzed using parsing technology to digitize the drawing information. Then, image segmentation technology is used to spatially divide the functional areas of each component structure in the construction drawings to be reviewed, and names (such as lobby, meeting room, office, etc.) are used to label and refer to the corresponding functional areas. When reviewing the drawings, after retrieving the target floor plan, the name of the component to be reviewed can be entered to locate and obtain the area labeled and referred to by the name of the component to be reviewed. This area contains all the structures of the component to be reviewed.

[0061] S102, select the area marked with the name of the stair component to obtain the first target area.

[0062] It should be noted that after selecting the area marked with the name of the stair component, the first target area contains all the planar structures of the stair component.

[0063] S103: Locate the plan view structure of the stair component in the first target area and review it to obtain the first review result of the stair component.

[0064] Specifically, the step of locating the plan view structure of the stair component in the first target area and reviewing it to obtain the first review result of the stair component includes:

[0065] Locate the planar stair flight group of the stair components in the first target area and examine the structure of the planar stair flight group;

[0066] If the structural review of the planar staircase group meets the requirements, the net width of the planar staircase group is obtained by analyzing and calculating based on the structure of the planar staircase group and the information of the contents of the staircase floor.

[0067] Locate the stair landings on both sides of the planar stair section group and determine whether the net width of the stair landings on both sides of the planar stair section group meets the requirements based on the net width of the planar stair section group.

[0068] It should be noted that a stair landing is the horizontal section connecting two sets of stairs, used for stair turns, connecting floors, or for users to rest after climbing a certain distance. Therefore, there are certain requirements for the width of the stair landing; for example, the clear width of the stair landing should not be less than the clear width of the stair flight.

[0069] Understandably, in this embodiment of the invention, after conducting an overall review of the planar structure of the stair components in the target plan drawing, a first review result can be obtained. Based on the obtained first review result, it can be determined whether the planar structure of the stair components meets the review requirements. If it does not meet the review requirements, it can indicate which specific step of the review failed or which specific part of the structure does not meet the requirements, and even mark it so that the designer can quickly find the problematic part of the construction drawing and make modifications and adjustments. If it meets the review requirements, then the first stage of review is passed.

[0070] Step S104: Retrieve the target cross-sectional view and locate the position of the name label of the stair component in the target cross-sectional view according to the input name of the stair component.

[0071] It should be noted that, in this embodiment of the invention, after the review of the target plan view is completed and the first review result is obtained, the second stage of review of the target cross-sectional view can be performed.

[0072] Step S105: Select the area marked with the name of the stair component to obtain the second target area.

[0073] It should be noted that after selecting the area marked with the name of the stair component, the first target area contains all the cross-sectional structures of the stair component.

[0074] Step S106: Locate the cross-sectional structure of the stair component in the second target area and review it to obtain the second review result of the stair component.

[0075] Specifically, the step of finding and reviewing the cross-sectional structure of the stair component in the second target area to obtain a second review result for the stair component includes:

[0076] Locate the cross-sectional stair section group of the stair components in the second target area and examine the structure of the cross-sectional stair section group;

[0077] If the structural review of the section staircase group meets the requirements, the structure of the section staircase group is analyzed to find the structure of the upper and lower staircase platforms connected to the section staircase group.

[0078] The structure of the upper and lower stair platforms of two adjacent cross-sectional stair groups is analyzed and calculated to obtain the distance between two adjacent directly opposite stair platforms, and the distance between two adjacent directly opposite stair platforms is used to determine whether the height requirement for human passage is met between the two adjacent cross-sectional stair groups.

[0079] It should be noted that, depending on their location, stair landings are divided into intermediate landings and floor landings. Floor landings are the area between the fire door and the staircase on each floor, while intermediate landings are the turning areas between two floors and between two staircases. Two adjacent floor landings or two adjacent intermediate landings are directly opposite each other. Based on the function and location of the stair landings, the height difference between two adjacent floor landings or two adjacent intermediate landings needs to meet the height requirements for people to walk through upright.

[0080] Understandably, in this embodiment of the invention, after conducting an overall review of the cross-sectional structure of the stair components in the target cross-sectional drawing, a second review result can be obtained. Based on the obtained second review result, it can be determined whether the cross-sectional structure of the stair components meets the review requirements. If it does not meet the review requirements, it can indicate which specific step of the review failed or which specific part of the structure does not meet the requirements, and even mark it so that the designer can quickly find the problematic part of the construction drawing and make modifications and adjustments. If it meets the review requirements, the review is passed.

[0081] In summary, based on the above-described method for reviewing building staircases using construction drawings, the following steps are taken: First, the target floor plan is retrieved, and the area marked with the name of the staircase component is located on the target floor plan according to the input name of the staircase component. This area is then selected to obtain a first target area. The floor plan structure of the staircase component is found within the first target area and reviewed to obtain a first review result. Next, the target sectional view is retrieved, and the location marked with the name of the staircase component is located on the target sectional view according to the input name of the staircase component. This area is then selected to obtain a second target area. The sectional view structure of the staircase component is found within the second target area and reviewed to obtain a second review result. This invention replaces the traditional manual review method for staircase components by comprehensively and automatically reviewing both the floor plan and sectional view to obtain the review result, and solves the problem of excessively long review cycles.

[0082] Example 2

[0083] This invention also proposes a method for reviewing building staircases based on construction drawings. The step of locating planar staircase groups of staircase components in the first target area and reviewing the structure of the planar staircase groups includes:

[0084] In the first target region, find a group of line segments that contain line segments of the same length, the same slope, and the same spacing.

[0085] If a group of line segments containing line segments of the same length, slope, and spacing is found, then the line segments of the same length, slope, and spacing are defined as planar trapezoidal segments, and the group of line segments containing line segments of the same length, slope, and spacing is defined as a group of planar trapezoidal segments.

[0086] Determine whether the length of each planar stair segment in the planar stair segment group is within a first preset length range and whether the spacing between two adjacent planar stair segments is within a preset spacing range, wherein the first preset length range may be 500mm to 1300mm and the preset spacing range may be 100mm to 400mm.

[0087] It should be noted that, in this embodiment of the invention, by searching for line segment groups containing straight line segments of the same length, slope and spacing in the first target area, each planar stair segment group of the stair component and the planar stair segment of each planar stair segment group can be found. Then, it is determined whether the length of the planar stair segment and the spacing between two adjacent planar stair segments meet the requirements, thereby ensuring the rationality of the structure of the planar stair segment group.

[0088] The step of analyzing and calculating the net width of the planar stair segment based on the structure of the planar stair segment group and the information of the contents of the stair floor includes:

[0089] Determine whether one or both ends of the planar stair segment in the planar stair segment group intersect with the contents of the staircase floor.

[0090] If both ends of the planar stair segment in the planar stair segment group intersect with the contents of the staircase floor, then find the midpoint of any planar stair segment and obtain the nearest intersection point on both sides of the midpoint, and set it as the target intersection point;

[0091] The distance between the two target intersection points is calculated to obtain the net width of the planar stair segment of the planar stair segment group.

[0092] After determining whether one or both ends of the planar stair segment in the planar stair segment group intersect with the contents of the staircase floor, the method further includes:

[0093] If one end of a planar stair segment in the planar stair segment group intersects with the contents of the staircase, then the endpoint of any planar stair segment that does not intersect with the contents of the staircase is taken as the starting point of the net width, and the intersection point closest to the starting point of the net width is taken as the ending point of the net width.

[0094] The distance between the starting point and the ending point of the net width is calculated to obtain the net width of the planar stair segment of the planar stair segment group.

[0095] It should be noted that the contents of the staircase can be a railing or a wall. Some staircases have a wall on one side and a railing on the other side, while some staircases have a wall on only one side. The analysis and calculation methods for the net width of the planar staircase in these two cases are different. The above steps can quickly and accurately calculate the net width of the planar staircase in both cases.

[0096] The steps of locating the stair landings on both sides of the planar stair flight group and determining whether the clear width of the stair landings on both sides of the planar stair flight group meets the requirements based on the clear width of the planar stair flight group include:

[0097] Obtain the outer rectangular outline of the planar stair segment group and construct the first circumscribed rectangle of the planar stair segment group with a first outward expansion distance, wherein the first outward expansion distance is less than the net width of the planar stair segment of the planar stair segment group;

[0098] Determine whether there exists a spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar stair segment group;

[0099] If there is no spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar stair segment of the planar stair segment group, then determine whether the net width of the planar stair segment of the planar stair segment group is greater than the preset net width.

[0100] If the net width of the planar stair segment of the planar stair segment group is greater than the preset net width, then the outer rectangular outline of the planar stair segment group is expanded outward along the direction perpendicular to the planar stair segment of the planar stair segment group to obtain the first expanded area.

[0101] Determine whether there are wall columns with a length greater than a preset length or doors with an opening direction perpendicular to the planar stair section group within the first outer expansion area;

[0102] If there are no wall columns with a length greater than the preset length or doors with an opening direction perpendicular to the planar stair section group within the first outer expansion area, then it is determined that the net width of the stair platforms on both sides of the planar stair section group meets the requirements.

[0103] It should be noted that the first outward expansion distance can be 500mm. By constructing the first circumscribed rectangle of the planar staircase group with the first outward expansion distance and determining whether there is a spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar staircase segment of the planar staircase group, it can be used to determine whether the planar staircase group is a staircase group from the first floor to the second floor. If the planar staircase group is not a staircase group from the first floor to the second floor, then there is an external wall above the stair landing on the first floor and at a distance of approximately 500mm from the outer staircase segment. The width of this external wall is less than the net width of the planar staircase segment. In this case, the net width of the stair landing on the first floor will not be reviewed. That is, if there is a spatial boundary line within the first circumscribed rectangle whose length is less than the net width of the planar staircase segment of the planar staircase group, the review of the planar staircase group ends. If it is not a staircase group from the first floor to the second floor, then the net width of the stair landing will be reviewed to see if it meets the requirements.

[0104] The preset clear width can be 1200mm, and the preset length can be the clear width of two planar stair sections plus a length of 200mm. Since the width of the edge wall of the stair landing (i.e., the intermediate platform) between two floors is equal to the clear width of two planar stair sections plus the width of the partition wall between the two planar stair section groups, by determining whether there is a wall column with a length greater than the preset length in the first extended area, and the width of the first extended area is the clear width of one planar stair section, if there is no wall column with a length greater than the preset length in the first extended area, it means that the edge wall of the stair landing (intermediate platform) is not in the first extended area, and it can be determined that the width of the stair landing is not less than the clear width of the planar stair section, which meets the review requirements; and by determining whether there is a door in the first extended area with an opening direction perpendicular to the planar stair section group, if there is no door in the first extended area with an opening direction perpendicular to the planar stair section group, it means that the opening door of the stair landing (floor platform) is not in the first extended area, and it can be determined that the width of the stair landing (floor platform) is not less than the clear width of the planar stair section, which meets the review requirements.

[0105] The step of determining whether the clear width of the planar stair segment of the planar stair segment group is greater than the preset clear width further includes:

[0106] If the net width of the planar stair segment of the planar stair segment group is not greater than the preset net width, then the first circumscribed rectangle is expanded outward by the preset net width along the direction perpendicular to the planar stair segment of the planar stair segment group to obtain the second expanded area, and it is determined whether there is a wall column with a length greater than the preset length in the second expanded area.

[0107] If there are no wall columns with a length greater than the preset length in the second outer expansion area, then the net width of the stair platforms on both sides of the planar stair group is determined to meet the requirements.

[0108] It should be noted that the above steps can determine whether the net width of the stair platform meets the requirements when the net width of the planar stair section of the planar stair group is not greater than the preset net width. When the net width of the planar stair section of the planar stair group is not greater than the preset net width, the net width of the stair platform should also be not less than a preset net width. This can fully meet the passage and turning requirements of the stair platform when carrying large goods.

[0109] Example 3

[0110] This invention also proposes a method for reviewing building staircases based on construction drawings. The step of locating the cross-sectional stair segment group of staircase components in the second target area and reviewing the structure of the cross-sectional stair segment group includes:

[0111] In the second target area, find a group of line segments that contains a preset number of end-to-end connected and mutually perpendicular straight line segments, wherein the preset number may be 6;

[0112] If a line segment group containing a preset number or more horizontal and vertical line segments that are connected end to end and perpendicular to each other is found, then the horizontal line segments in the horizontal and vertical line segments are set as cross-sectional horizontal trapezoidal segments, the vertical line segments in the horizontal and vertical line segments are set as cross-sectional vertical trapezoidal segments, and the line segment group containing a preset number or more horizontal and vertical line segments that are connected end to end and perpendicular to each other is set as a cross-sectional trapezoidal segment group.

[0113] Determine whether the lengths of the horizontal and vertical sections in the section segment group meet the requirements. Specifically, determine whether the length of the horizontal section in the section segment group is within the range of 100mm to 400mm and the length of the vertical section is within the range of 100mm to 300mm.

[0114] It should be noted that, in this embodiment of the invention, by searching for a predetermined number of horizontal and vertical line segments that are connected end to end and perpendicular to each other in the second target area, each section of the staircase component and the section of each section of the staircase segment group can be found. Then, it is determined whether the length of the section of the staircase meets the requirements, thereby ensuring the rationality of the structure of the planar staircase group.

[0115] The step of analyzing the structure of the cross-sectional staircase group to find the structure of the upper and lower staircase platforms connected to the cross-sectional staircase group includes:

[0116] Find the lowest point of each of the said profile step groups, and calculate the vertical distance between the lowest points of two adjacent profile step groups;

[0117] Determine whether the vertical distance between the lowest points of two adjacent cross-sectional stepped groups is less than a preset vertical distance, wherein the preset vertical distance can be 100mm;

[0118] If the vertical distance between the lowest points of two adjacent profile ladder groups is less than a preset vertical distance, then it is determined whether there is an intersection between the two adjacent profile ladder groups.

[0119] If there is no intersection between two adjacent sets of the cross-sectional staircases, then find the upper and lower structural surfaces of the upper and lower staircase platforms connected to the cross-sectional staircase sets.

[0120] It should be noted that the vertical distance between the lowest points of two adjacent sets of stair sections is less than a preset vertical distance. If the vertical distance between the lowest points of two adjacent sets of stair sections is less than the preset vertical distance, it indicates that there is a risk that the height between the stair platforms of the two floors is too low and inconvenient for passage. Therefore, it is necessary to examine the height between the stair platforms of the two floors.

[0121] The step of determining whether there is an intersection between two adjacent sets of the cross-sectional stepped segments further includes:

[0122] If there is an intersection between two adjacent sets of the cross-sectional ladder segments, then the two adjacent sets of the cross-sectional ladder segments are determined to be scissor ladders, and the review ends.

[0123] It should be noted that a scissor staircase is a pair of overlapping but non-connected staircases set up in the same stairwell. There are two staircases in the same stairwell, with a bend in the middle between the upper and lower floors. The staircases of the three floors are like a pair of scissors. If the staircase is determined to be a scissor staircase, the examination method of the present invention will not be used to continue the subsequent examination.

[0124] In this embodiment of the invention, another method can be used to analyze the structure of the cross-sectional staircase group to find the structure of the upper and lower staircase platforms connected to the cross-sectional staircase group:
