The second target rafter is a roof rafter adjacent to the tiger window reinforcing steel beam on the system roof truss; the adjacent algorithm is a method for converting the adjacent relation between the sub-elements into an intersecting relation and judging whether the sub-elements are adjacent or not according to the intersecting relation.
Specifically, the adjacency algorithm is a computer program stored in a memory of the computer device for executing an adjacency judgment operation, and after receiving an instruction for triggering the adjacency judgment operation, the computer device executes the adjacency judgment operation on the selected sub-element to obtain a target sub-element adjacent to the selected sub-element. In this embodiment, after receiving an adjacency judgment instruction triggered by the bottom guide beam, a computer device performs adjacency judgment on the bottom guide beam, judges whether a virtual entity extending from the bottom guide beam intersects with other sub-elements of the tiger window except the bottom guide beam and/or a roof rafter of the system roof truss, so as to judge whether the bottom guide beam is adjacent to the other sub-elements and/or the roof rafter, and determines the adjacent tiger window sub-elements and/or the roof rafter. If the virtual entity does not intersect the other sub-elements and/or the roof rafters, the bottom guide beam is not adjacent to the sub-elements and/or the roof rafters; if the virtual entity intersects with the other sub-elements and/or the roof rafters, the bottom guide beam is adjacent to the sub-elements and/or the roof rafters. As shown in fig. 2, it is found according to the adjacency algorithm that the reinforcing steel beam 221 is adjacent to the roof rafter 111, and the reinforcing steel beam 222 is adjacent to the roof rafter 115, so that the roof rafters 111 and 115 are the second target rafters 12.

and generating a reinforced fixed node on the maximum surface of the reinforced steel beam along the generating line of the reinforced steel beam according to the preset generating rule so as to fixedly connect the reinforced steel beam with the system roof truss.
Specifically, the computer device acquires a surface having a largest area as the maximum surface according to an area of each surface of the reinforcing steel beam. And on the maximum surface, generating the reinforced fixed node based on the specification of the maximum surface and the specification of the reinforced fixed node along the generating line direction of the reinforced steel beam. As shown in fig. 8, taking the reinforced steel beam 221 as an example, the reinforced steel beam 221 is a C-shaped steel with an opening facing left, a maximum surface of the reinforced steel beam 221 contacts with a maximum surface of the roof rafter 111, and on a maximum surface of the reinforced steel beam 221, a reinforcing and fixing node B is generated on a center line of the maximum surface in a direction perpendicular to the maximum surface according to a setting rule of 150mm end-to-end distance and 300mm distance, so that the reinforced steel beam 221 is fixedly connected with the second target rafter.
In this embodiment, a first cross direction which is the same as a Z-axis in a forward direction or a reverse direction is obtained by crossing a direction of a generating line of the reinforced steel beam with a direction of a generating surface of the tiger window, and attribute information of the reinforced steel beam with the smallest element length is obtained to obtain the reinforced steel beam in the sub-elements, a second target rafter on the system roof truss adjacent to the reinforced steel beam is obtained according to an adjacent algorithm, and the reinforcing fixed node is automatically generated based on a relative positional relationship between the reinforced steel beam and the second target rafter so as to try to fixedly connect the reinforced steel beam of the tiger window with the second target rafter. By the method, manual design and finding of the reinforcing fixed node of the tiger window can be avoided, time consumption is reduced, and generation efficiency is improved.
As shown in fig. 9, the sub-elements include a first sub-element and a second sub-element, and the neighbor algorithm includes:
step S901, acquiring all surfaces in the first sub-element; and respectively generating virtual entities with preset sizes along the normal direction of each surface based on all the surfaces. Wherein the all surfaces include respective surfaces constituting the first sub-element.
Specifically, the computer device obtains each wall surface constituting the first sub-element. As shown in fig. 10, in the present embodiment, the first subelement Q1 is a U-shaped steel, and includes three surfaces. The computer device takes each surface in all the surfaces as a starting surface, and generates virtual entities with preset sizes along the normal direction of the surfaces respectively. As shown in fig. 10, three virtual entities T1 to T3 are obtained by deriving a certain distance on each of the three surfaces.
Step S902, determining whether each of the virtual entities intersects with the second sub-element, to obtain an intersection state between the virtual entities and the second sub-element.
Wherein the intersection states include intersections and disjointedness. Specifically, the computer device determines whether spatial coordinates of the virtual entity and a second sub-element with preset sizes in the design model overlap, if so, the virtual entity and the second sub-element intersect, and if not, the virtual entity and the second sub-element do not intersect.
Step S903, obtaining the adjacent judgment result of the first sub-element and the second sub-element according to the intersection state between the virtual entity and the second sub-element.
The first sub-element and the second sub-element are different sub-elements, and the terms "first" and "second" are only used for distinguishing the two sub-elements, and do not limit the embodiments of the present application. Specifically, if the virtual entity and the second sub-element intersect, the first sub-element is adjacent to the second sub-element, and if the virtual entity and the second sub-element do not intersect, the first sub-element is not adjacent to the second sub-element.
In one embodiment, as shown in fig. 11, the target steel beams include a highest ridge steel beam of the tiger window and an engaging steel beam, the engaging steel beam is a steel beam of the roof truss of the tiger window adjacent to the roof rafter of the system roof truss, and the step S101 of obtaining the target steel beam includes:
step 1101, acquiring the Z-axis heights of the generating line midpoints of all the sub-elements, and taking the sub-element with the maximum Z-axis height of the generating line midpoint as the highest roof girder.
Specifically, the computer device obtains Z-axis coordinates of the midpoints of the generating lines of all the sub-elements, arranges values of the Z-axis coordinates in a descending order to obtain a Z-axis ranking table including the Z-axis coordinate values of all the sub-elements, and obtains the sub-element corresponding to the largest Z-axis coordinate value in the Z-axis ranking table as the highest roof steel beam. The sub-element obtained according to the maximum Z-axis coordinate value is the highest roof girder, and in fig. 2, the sub-element is located below the first folding plate connecting piece and is shielded by the first folding plate connecting piece.
Step 1102, the highest roof girder comprises a first endpoint and a second endpoint, and a first direction in which the first endpoint points to the second endpoint is obtained.
Specifically, the computer device obtains a first direction in which the first endpoint points to the second endpoint. As shown in fig. 12, when the AA end of the highest roof girder is taken as the first end point and the BB end is taken as the second end point, the first direction f1 is that the AA end points to the BB end.
Step 1103, obtaining a linear distance between the second end point and a middle point of a generating line of each sub-element of the C-shaped steel in the tiger window according to the second end point corresponding to the first direction which is the same as the direction of the generating surface of the tiger window, and using the sub-element of the tiger window with the largest linear distance as the connecting steel beam.

And if the first direction is opposite to the direction of the generation surface of the tiger window, the first endpoint is the point S. And the computer equipment acquires the linear distance between the second end point and the midpoint of the generating line of each sub-element of the C-shaped steel in the slot, arranges the linear distances in a descending order to obtain a distance list, and takes the corresponding sub-element of the C-shaped steel in the slot as the connecting steel beam when the linear distance in the distance list is the maximum. In this embodiment, the linear distance from the second end point S on the tiger window 20 is the largest, and the C-shaped steel sub-element is the connecting steel beam, and is shielded by the third flap connector of the second flap connector in fig. 13.
