In fig. 2, 4 rectangles are wall column contour lines, 2 line segments in the vertical direction are contour lines of the main beams, and 9 line segments in the horizontal direction are initial contour lines of the secondary beams. In fig. 2, L1(3) indicates that the number of beam spans corresponding to the beam number L1 of the secondary beam is 3, that is, L1 is 3 spans, L2(2) indicates that the number of beam spans corresponding to the beam number L2 of the secondary beam is 2, that is, L2 is 2 spans, and the initial contour line of the secondary beam includes a secondary beam L1 and a secondary beam L2.
In one embodiment, obtaining the number of beams and the number of beam spans of the secondary beam comprises: identifying a beam lead corresponding to the secondary beam; identifying a label corresponding to the beam lead; and extracting the beam number and the beam span number from the corresponding label of the beam lead.
A beam leg refers to a line segment near the secondary beam that is perpendicular to the original contour of the secondary beam. And the marks of the secondary beams are arranged near the beam lead, and the marks of the secondary beams comprise the beam numbers and the beam span numbers of the secondary beams. Therefore, the beam number and the beam span number of the secondary beam can be extracted from the label corresponding to the beam lead.
And 103, acquiring the total number of the line segments in the initial contour line and the number of the line segments in each part of the initial contour line which is cut off by the contour line of the main beam.
In fig. 2, the total number of line segments in the initial contour line of the secondary beam is 9, the initial contour line is truncated into 3 parts by the contour line of the primary beam, the number of line segments in the first part on the left is 3, the number of line segments in the second part in the middle is 3, and the number of line segments in the third part on the right is 3.
And step 104, determining the number of the target line segments corresponding to each beam number according to the total number of the line segments, the beam numbers and the beam span number.
In fig. 2, the total number of line segments is 9, the number of line segments in the first portion on the left is 3, the number of line segments in the second portion in the middle is 3, the number of line segments in the third portion on the right is 3, the number of beam spans corresponding to the beam number L1 is 3, the number of beam spans corresponding to the beam number L2 is 2, and according to these pieces of information, the target number of line segments corresponding to the beam number L1 and the target number of line segments corresponding to the beam number L2 are determined.
In a specific embodiment, as shown in fig. 3, determining the number of target line segments corresponding to each beam number according to the total number of line segments, the number of beams, and the number of beam spans includes:
and 301, taking the beam span number corresponding to the beam number as the first line segment number corresponding to the beam number.
And step 302, taking the sum of the line segment numbers of all target parts in the initial contour line as the second line segment number corresponding to the beam number, wherein all the target parts are continuous, and the number of the target parts is the beam span number.
And 303, selecting one of the first line segment quantity and the second line segment quantity as a target line segment quantity corresponding to the beam number according to a preset rule, wherein the preset rule is that the sum of the target line segment quantities corresponding to the beam numbers is equal to the total line segment quantity.
The number of target line segments corresponding to the beam number only has two calculation modes, one is that the number of the target line segments corresponding to the beam number is the number of the beam spans corresponding to the beam number, namely each line segment is one span, and the other is that the number of the target line segments corresponding to the beam number is the sum of the number of the line segments of the target part with the number of the beam spans in the initial contour line, namely each target part is one span. The number of the target line segments corresponding to each beam number can be accurately obtained as long as the sum of the number of the target line segments corresponding to each beam number is equal to the total number of the line segments, so that the actual situation is ensured to be met, the number of the target line segments corresponding to each beam number can be automatically obtained, and manual confirmation is not needed.
In fig. 2, the number of beam spans corresponding to the beam number L1 is s1=3, the number of first line segments n1=3 corresponding to the beam number L1, the number of target portions is s1=3, the number of second line segments n2 corresponding to the beam number L1 is the sum of the numbers of line segments of the 3 target portions in the initial contour line, the number of line segments in the first portion on the left is 3, the number of line segments in the second portion in the middle is 3, and the number of line segments in the third portion on the right is 3, so n2=3+3= 9. The number of target line segments corresponding to the beam number L1 is n1=3 in the first case, and n2=9 in the second case, and since the beam number L1 occupies all line segments in the initial contour line and no line segment is left for the beam number L2 when n2=9, which is not practical, the number of target line segments corresponding to the beam number L1 can only be n1=3 and occupies the first portion on the left side in the initial contour line.
The number of beam spans corresponding to the beam number L2 is s1=2, the number of first line segments n1=2 corresponding to the beam number L2, the number of target portions is s1=2, the number of second line segments n2 corresponding to the beam number L2 is the sum of the number of line segments of the first 2 target portions remaining after L1 is removed from the initial contour line, the number of line segments in the middle second portion is 3, and the number of line segments in the right third portion is 3, so n2=3+3= 6. The target line segment number corresponding to the beam number L2 is n1=2 in the first case and n2=6 in the second case, and when the target line segment number corresponding to the beam number L2 is n1=2, the target line segment number n1=3 corresponding to the beam number L1 is added to the target line segment number n1=2 corresponding to the beam number L2, and the sum is 3+2=5 and is not equal to 9, which is not practical, so that the target line segment number corresponding to the beam number L2 cannot be n1= 2. When the target line segment number corresponding to the beam number L2 is n2=6, the target line segment number n1=3 corresponding to the beam number L1 is added to the target line segment number n2=6 corresponding to the beam number L2, and the sum obtained is 3+6=9, which is equal to the total number of line segments, and thus, the method meets the actual situation. Therefore, the target line segment number corresponding to the beam number L1 is n1=3, and the target line segment number corresponding to the beam number L2 is n2= 6.
In a specific embodiment, as shown in fig. 4, determining the number of target line segments corresponding to each beam number according to the total number of line segments, the number of beams, and the number of beam spans includes:
and step 401, circularly reading the beam number from the beam number list.
And step 402, acquiring the beam span number s1 corresponding to the read beam number L.
In step 403, s1 is used as the number n1 of the first segments corresponding to the beam number L.
And step 405, acquiring the total number S of the line segments in the initial contour line of the secondary beam, and calculating the total number S = S-n 1 of the remaining line segments.
At step 408, the association (L, n 2) is stored.
In step 409, the total number of remaining line segments S = S-n 2 is calculated.
And 105, determining target line segments needing to be spliced in the initial contour line according to the number of the target line segments and the number of the beam spans, and splicing the target line segments to generate an accurate contour line of the beam member.
In one embodiment, as shown in fig. 5, the wall column contour line and the precise contour line of the beam member are schematically illustrated. Fig. 5 is a diagram illustrating the target line segments spliced on the basis of fig. 2 to generate an accurate contour line of the beam member. In fig. 5, the thick solid line is a target line segment, the first portion on the left side has no target line segment, the second portion in the middle has 2 target line segments, and the third portion on the right side has 2 target line segments. After the target line segment is spliced, the first part on the left is a secondary beam contour line corresponding to the beam number L1 and is a 3-span beam, the second part in the middle and the third part on the right are secondary beam contour lines corresponding to the beam number L2 and are 2-span beams, the second part in the middle is a span, and the third part on the right is a span.
