Description

Technical Field

[0001] The invention relates to the technical field of auxiliary building design, and in particular to an intelligent design method for building stairs based on a Grasshopper platform. Background Art

[0002] As vertical transportation in buildings, stairs are an important part of architectural design. The quality of staircase design affects the traffic flow of buildings and the safety of personnel evacuation. In the past, there were two ways to design stairs: 1. Manual creation, which requires manually calculating the required riser height and number of steps based on the size of the stairwell design and the floor height, and then manually drawing. When it comes to staircase designs of unequal runs, multiple runs, and different sides of the upward passage, it takes a lot of time to calculate and verify before drawing. Moreover, when the drawings are changed, they need to be re-designed, which takes a lot of time and energy, and is inefficient. 2. Plug-in generation. At present, the drawing effect of this type of plug-in is not comprehensive enough. For example, there is no option for the net depth of the stairs, and it is impossible to determine the staircase plan in the first time, and it is impossible to determine whether the net height of the stair section meets the requirements; there is no built-in staircase-related specifications, such as the step height can be set to any value; the stair section can only be drawn for a single stair section, and the relevant parameters of the stair section need to be known in advance, and there is no way to control it from the overall perspective; it is only suitable for double runs, and the generated plane and section are not marked.

[0030] Step S3-7A: If step S3-6A only screens out one of the three-screen step height TBG ss , then it is determined as the equal running plan step height TBG dp ;

[0031] If step S3-6A only screens out at least two of the three-screen step heights TBG ss , then: if the parameter of whether the even number is set to yes, the even number of three-screen run PS is screened out ss The corresponding three-screen step height TBG ss Recorded as the four-screen step height TBG sis ; If the parameter of whether the even number is set to no, the odd number of three-screen run PS is screened out ss The corresponding three-screen step height TBG ss Recorded as the four-screen step height TBG sis ;

[0049] in:

[0050] In step S2, the known parameters of the target building staircase include: the upward direction of the first floor section and the filling direction of the first floor section; wherein the upward direction of the first floor section indicates the upward direction of the staircase flight of the target building staircase defined as the first floor in the section view, including two cases of upward left and upward right; the filling direction of the first floor section indicates the filling method adopted by the outline of the single-flight staircase of the target building staircase defined as the first floor in the section view, including two cases of solid filling and hollow filling. Since the filling method adopts an alternating method of solid filling and hollow filling, when the filling method of the first floor is determined, the filling methods of the remaining floors are also determined;

[0051] In step S3, the globally adjustable parameters include: stair thickness LTHD, ladder beam height TLG, ladder beam height TLK, main beam height ZLG, and main beam width ZLK corresponding to each floor; wherein the stair thickness LTHD is the minimum distance from the step to the bottom of the stair flight;

[0052] In step S4, the building staircase section construction drawing generation battery pack generates the splicing point and splicing section construction drawing of any floor, and the steps are as follows:

[0053] Step S4-1: According to the upward direction of the first floor section, the step width TBK in the comprehensive design scheme, and the step height TBG of the equal running scheme dp Or unequal running of the specified stair step height, unequal running of the remaining stair step height, use the Line SDL battery built into the Grasshopper plug-in to draw a single step profile; then use the LinearArray battery built into the Grasshopper plug-in to first use the single step profile, the single step level TDJS of the equal running scheme in the comprehensive design scheme dp Or unequal running of specified steps, PS zd -1 The unequal number of steps of the remaining staircases and the stair thickness LTHD are used to draw the outline of the staircase, and then the maximum rest platform width PTK in the comprehensive design scheme is calculated. jx , opposite side platform width PTK yc and the thickness of the stairs LTHD, the rest platform contour line and the opposite platform contour line are respectively extended from the staircase flight contour line, and the ladder beam contour line and the main beam contour line are respectively extended according to the ladder beam height TLG, the ladder beam height TLK, the main beam height ZLG, and the main beam width ZLK, so that the staircase flight contour line, the rest platform contour line, the opposite platform contour line, the ladder beam contour line and the main beam contour line constitute a single-staircase flight contour line; and a preset number of single-staircase flight contour lines are mirrored and copied through the Mirror battery built into the Grasshopper plug-in;

[0054] Step S4-2, according to the filling direction of the first-floor section, the single-flight staircase contour lines drawn in step S4-1 are filtered out by the Stream Filter cell to be filled with solid, and the filtered single-flight staircase contour lines are filled with solid by the Define Hatch cell derived from the Elefront plug-in;

[0055] Step S4-3, using the Offset Curve cell, offset the top edge line of the single-flight stair contour line by 50 mm to determine it as the upper layer line of the staircase;

[0056] Step S4-4, using the Offset Curve Loose cell, the top edge line of the single-flight staircase contour line is offset downward by 20 mm to determine it as the lower layer line of the stairs;

[0057] Step S4-5, extract the two endpoints of the upper layer line of the stairs, draw a 900mm straight line upwards through the Line SDL cell, and connect the endpoints of the two straight lines through the Line cell to draw a handrail line;

[0058] Step S4-6, using the Line SDL cell, draw a 300mm straight line, a 2200mm straight line, and a 300mm straight line to the outside, the top, and the inside of the two end points of the upper layer line of the stairs, and connect the final two end points to draw a clearance line;

[0059] Step S4-7, use the Define Linear Dimension cell of the Elefront plug-in to mark, including the horizontal platform, staircase, left floor height and right single staircase height. Connect the corresponding points and select the marking style. The value of the horizontal staircase needs to be modified to: step width x (number of levels - 1) = actual value, and the value of the right staircase height needs to be modified to: step height x number of levels = actual value.

[0060] Step S4-8, accumulating according to the gradient height, and elevating the contour line of the rest platform and the contour line of the opposite side platform;

[0061] Thus, each single-flight staircase outline and the graphics and annotations drawn therefor in steps S4-2 to S4-8 form a splicing section construction drawing of the corresponding floor.

[0062] Wherein: in the step S5, the overall splicing battery pack of the building staircase section construction drawing is to splice the splicing section construction drawings of each floor drawn in step S4 into the overall section construction drawing of the target building staircase, and the steps are as follows:

[0063] Step S5-1, cache the splicing section construction drawing of each floor through the Data Recorder battery, and extract the point obtained by moving the left end point of the upper layer line of the stairs in the splicing section construction drawing upward by a distance of the floor height CG as the splicing point of the floor;

[0064] Step S5-2, using the Move To Point cell of the Pufferfish plug-in, in the splicing section construction drawing of two adjacent floors, the splicing point of the next floor is made to coincide with the left end point of the upper layer line of the stairs of the previous floor, so as to realize the positioning splicing of the splicing section construction drawings of the two adjacent floors, and splicing to form the overall section construction drawing of the stairs of the target building;

[0065] Step S5-3: Calculate the actual staircase thickness LTHD in the joint section construction drawing of each floor sj =TLJJ xl ÷25, and LTHD sj Round up; where TLJJ xl Indicates the clear distance between adjacent ladder beams of the floor, which is the horizontal distance between the two ladder beam outlines on both sides of the staircase outline in the splicing section construction drawing of the floor;

[0066] Among them, the purpose of step S5-3 is mainly to take into account the structural factors affecting the design of the stair segment. The traditional design method is that the architectural designer pre-assumes a stair tread thickness according to the empirical value to draw the building stair segment, and submits the staircase drawing to the structural professional for stair tread, rest platform, and stair beam bearing capacity calculation. The structural professional then submits the cross-section of the stair tread, stair beam, and rest platform to the architectural professional to review the net height of the stair segment and make adjustments. The whole process consumes a lot of manpower and time. Through the program's intelligent algorithm and the powerful computing power of the computer, the program can comprehensively analyze and obtain the best design solution, which can shorten this process to a few minutes and generate a staircase design that meets the requirements of the structural professional.

[0067] Step S5-4: Use the Data Dam battery to calculate the actual stair thickness LTHD of each floor calculated in step S5-3 sj Push to the global adjustable parameters to replace the value of the stair thickness LTHD of each floor of the global adjustable parameters with the corresponding actual stair thickness LTHD sj ;

[0068] Furthermore, according to the stair thickness LTHD after the replacement value, step S4, step S5-1 and step S5-2 are re-executed to re-assemble the overall cross-section construction drawing of the target building staircase as the final result.

[0069] As a preferred embodiment of the present invention: in the step S1, based on the Grasshopper plug-in, the following is also created: a three-dimensional model of a building staircase generates a battery pack;

[0070] The building staircase intelligent design method also includes:

[0071] Step S6, executing the building staircase three-dimensional model generation battery pack to generate the overall cross-sectional construction drawing of the target building staircase into the building staircase three-dimensional model of the target building staircase, the specific steps are:

[0072] Step S6-1, grouping the spliced ​​section construction drawings of each floor in the overall section construction drawing according to the filling direction of the first floor section, recording them as solid new filling groups and hollow filling groups respectively, and covering them with Patch cells according to the filling direction of the first floor section;

[0073] Step S6-2: Use the Extrude cell to stretch the overall section construction drawing by a distance of (LTJK-TJK)÷2, where LTJK represents the net width of the stairs, TJK represents the width of the stairwell, the solid new filling group is stretched forward, and the hollow filling group is stretched backward to obtain the three-dimensional model of the building staircase of the target building staircase, see Figure 3 .

[0074] As a preferred embodiment of the present invention: in the step S1, based on the Grasshopper plug-in, the following is also created: generating a battery pack from a plane construction drawing;

[0075] The building staircase intelligent design method also includes:

[0076] Step S7, execute the plan construction drawing generation battery group to generate the overall section construction drawing of the target building staircase into the plan construction drawing of the target building staircase, the specific steps are: according to the overall section construction drawing, the Move To Point battery of the Pufferfish plug-in is used to locate on the staircase flight contour line of each floor to generate the plan construction drawing of each floor of the target building staircase, including six parts: staircase contour, elevation and arrow, middle flight line, evacuation line, annotation, and plane text, see Figure 4 Among them, by using arrows to generate battery packs, arrow graphics can be automatically generated. According to the position of the upper or lower text, the correct arrow position can be generated by setting the angle.

[0077] In addition, you can bake (i.e. import) all the elements generated in Grasshopper into Rhino through the Bake All Elements battery, and use the python battery to export the DWG file with one click.

[0078] Compared with the prior art, the present invention has the following beneficial effects:

[0079] First, the present invention only requires the building staircase designer to fill in the known parameters of the target building staircase in an Excel table and set the global adjustable parameters in the Rhino software. Then, the battery group created in the Grasshopper plug-in can be used to generate equal run suggestion schemes and unequal run suggestion schemes as comprehensive design schemes according to whether the net height JG under the ladder beam is set. The splicing section construction drawing, the overall section construction drawing, the building staircase three-dimensional model and the plan construction drawing of each floor of the target building staircase are generated according to the comprehensive design scheme. The present invention has the advantages of fast modeling speed, high efficiency, high accuracy, good integrity and strong ease of use.

[0080] Second, the present invention optimizes the net depth of the stairs in step S3-3A and step S3-4A, which can reduce the common area of ​​the stairs of the target building and improve the commercial value of the building.

[0081] Third, the present invention can generate non-recommended plans, automatically draw stairs and correct system errors during the entire process from plan to construction drawing for stair designers, which is convenient and efficient, saves drawing time, and reduces the error rate.

[0130] in:

[0131] In step S2, the known parameters of the target building staircase include: the upward direction of the first floor section and the filling direction of the first floor section; wherein the upward direction of the first floor section indicates the upward direction of the staircase flight of the target building staircase defined as the first floor in the section view, including two cases of upward left and upward right; the filling direction of the first floor section indicates the filling method adopted by the outline of the single-flight staircase of the target building staircase defined as the first floor in the section view, including two cases of solid filling and hollow filling. Since the filling method adopts an alternating method of solid filling and hollow filling, when the filling method of the first floor is determined, the filling methods of the remaining floors are also determined;

[0132] In step S3, the globally adjustable parameters include: stair thickness LTHD, ladder beam height TLG, ladder beam height TLK, main beam height ZLG, and main beam width ZLK corresponding to each floor; wherein the stair thickness LTHD is the minimum distance from the step to the bottom of the stair flight;

[0133] In step S4, the building staircase section construction drawing generation battery pack generates the splicing point and splicing section construction drawing of any floor, and the steps are as follows:

[0134] Step S4-1: According to the upward direction of the first floor section, the step width TBK in the comprehensive design scheme, and the step height TBG of the equal running schemedp Or unequal running of the specified stair step height, unequal running of the remaining stair step height, use the Line SDL battery built into the Grasshopper plug-in to draw a single step profile; then use the LinearArray battery built into the Grasshopper plug-in to first use the single step profile, the single step level TDJS of the equal running scheme in the comprehensive design scheme dp Or unequal running of specified steps, PS zd -1 The unequal number of steps of the remaining staircases and the stair thickness LTHD are used to draw the staircase contour line A, and then the maximum rest platform width PTK in the comprehensive design scheme is calculated. jx , opposite side platform width PTK yc and the stair thickness LTHD, the rest platform contour line B and the opposite platform contour line C are respectively extended from the stair flight contour line A, and the ladder beam contour line D and the main beam contour line E are respectively extended according to the ladder beam height TLG, the ladder beam height TLK, the main beam height ZLG, and the main beam width ZLK, so that the stair flight contour line A, the rest platform contour line B, the opposite platform contour line C, the ladder beam contour line D and the main beam contour line E constitute a single-stair flight stair contour line; and a preset number of single-stair flight stair contour lines are mirrored and copied through the Mirror battery built into the Grasshopper plug-in;

[0135] Step S4-2, according to the filling direction of the first-floor section, the single-flight staircase contour lines drawn in step S4-1 are filtered out by the Stream Filter cell to be filled with solid, and the filtered single-flight staircase contour lines are filled with solid by the Define Hatch cell derived from the Elefront plug-in;

[0136] Step S4-3, using the Offset Curve cell, offset the top edge line of the single-flight stair contour line by 50 mm to determine it as the upper layer line of the staircase;

[0137] Step S4-4, using the Offset Curve Loose cell, the top edge line of the single-flight staircase contour line is offset downward by 20 mm to determine it as the lower layer line of the stairs;

[0138] Step S4-5, extract the two endpoints of the upper layer line of the stairs, draw a 900mm straight line upwards through the Line SDL cell, and connect the endpoints of the two straight lines through the Line cell to draw a handrail line F;

[0139] Step S4-6, using the Line SDL cell, draw a 300 mm straight line, a 2200 mm straight line, and a 300 mm straight line to the outside, the top, and the inside of the two end points of the upper layer line of the stairs, and connect the final two end points to draw a clearance line G;

[0140] Step S4-7, use the Define Linear Dimension cell of the Elefront plug-in to mark, including the horizontal platform, staircase, left floor height and right single staircase height. Connect the corresponding points and select the marking style. The value of the horizontal staircase needs to be modified to: step width x (number of levels - 1) = actual value, and the value of the right staircase height needs to be modified to: step height x number of levels = actual value.

[0141] Step S4-8, accumulating according to the gradient height, and elevating the contour line B of the rest platform and the contour line C of the opposite side platform;

[0142] Thus, each single-flight staircase outline and the graphics and annotations drawn therefor in steps S4-2 to S4-8 form a splicing section construction drawing of the corresponding floor.

[0143] Wherein: in the step S5, the overall splicing battery pack of the building staircase section construction drawing is to splice the splicing section construction drawings of each floor drawn in step S4 into the overall section construction drawing of the target building staircase, and the steps are as follows:

[0144] Step S5-1, cache the splicing section construction drawing of each floor through the Data Recorder battery, and extract the point obtained by moving the left end point of the upper layer line of the stairs in the splicing section construction drawing upward by a distance of the floor height CG as the splicing point of the floor;

[0145] Step S5-2, using the Move To Point cell of the Pufferfish plug-in, in the splicing section construction drawing of two adjacent floors, the splicing point of the next floor is made to coincide with the left end point of the upper layer line of the stairs of the previous floor, so as to realize the positioning splicing of the splicing section construction drawings of the two adjacent floors, and splicing to form the overall section construction drawing of the stairs of the target building;

[0146] Step S5-3: Calculate the actual staircase thickness LTHD in the joint section construction drawing of each floor sj =TLJJ xl ÷25, and LTHD sj Round up; where TLJJ xl It indicates the clear distance between adjacent ladder beams of the floor, which is the horizontal distance between the two ladder beam outlines D on both sides of the staircase outline A in the splicing section construction drawing of the floor;

[0147] Among them, the purpose of step S5-3 is mainly to take into account the structural factors affecting the design of the stair segment. The traditional design method is that the architectural designer pre-assumes a stair tread thickness according to the empirical value to draw the building stair segment, and submits the staircase drawing to the structural professional for stair tread, rest platform, and stair beam bearing capacity calculation. The structural professional then submits the cross-section of the stair tread, stair beam, and rest platform to the architectural professional to review the net height of the stair segment and make adjustments. The whole process consumes a lot of manpower and time. Through the program's intelligent algorithm and the powerful computing power of the computer, the program can comprehensively analyze and obtain the best design solution, which can shorten this process to a few minutes and generate a staircase design that meets the requirements of the structural professional.

[0148] Step S5-4: Use the Data Dam battery to calculate the actual stair thickness LTHD of each floor calculated in step S5-3 sj Push to the global adjustable parameters to replace the value of the stair thickness LTHD of each floor of the global adjustable parameters with the corresponding actual stair thickness LTHD sj ;

[0149] Furthermore, according to the stair thickness LTHD after the replacement value, step S4, step S5-1 and step S5-2 are re-executed to re-assemble the overall cross-section construction drawing of the target building staircase as the final result.
