Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The method for generating the variable cross-section splicing node of the column factory can be applied to an application environment shown in fig. 1. The terminal 100 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers. The terminal 100 includes a memory, a processor and a display. The processor may run building design software, which may be stored in the memory in the form of a computer program. The memory also provides an operating environment for the building design software, and the memory may store operating information for the building design software. Specifically, the display screen can display a design interface of the building design software, and a user can input information through the design interface to perform building design. In one embodiment, as shown in fig. 2, a method for generating a variable cross-section splicing node of a column factory is provided, and an example of application of the method to the terminal in fig. 1 is described.

As shown in fig. 3, the columns of the light steel structure generally comprise 3 types, namely an H-type column, a box-type column and a round column. The attribute information of the H-shaped column and the box-shaped column comprises a flange width, a flange thickness, a flange orientation, a web width, a web thickness, a web orientation and the like besides the length and the generating point. The attribute information of the circular column is basically consistent with that of the H-shaped column and the box-shaped column, but note that the flange width and the web width of the circular column are consistent and are not distinguished.

The method specifically comprises the following steps:

and 210, acquiring a column in the light steel structure design interface according to the type of the element in the design interface, the generation position of the element and the attribute information of the element.

Specifically, the processor may obtain operation information of the architectural design software from the memory, and obtain, according to the operation information, a type of an element in the current design interface, a generation position of the element, and attribute information of the element. And then acquiring the column in the light steel structure design interface according to the type of the element in the design interface, the generation position of the element and the attribute information of the element.

Optionally, the processor may identify the element of the light steel structure in the design interface according to the generation position of the element and the attribute information of the element, and then identify the column in the light steel structure.

And step S220, screening the columns according to the adjacent information of the columns to obtain column combinations.

The column combination at least comprises two columns which accord with the preset relative position relationship, and optionally, the preset relative position relationship of the columns in the column combination can be an up-down position relationship.

Specifically, the processor screens the columns according to the adjacent information of the columns to obtain column combinations. The processor screens out columns without adjacent columns above and below. The columns without adjacent columns at the upper and lower parts do not need to be placed with connecting nodes.

Optionally, if there is an adjacent column above and/or below a certain column, the processor combines the certain column and the adjacent column of the certain column as a column combination.

Step S230, if the orientation information, the cross-section size, and the center point or the flange direction relative position of each column in the column combination meet preset conditions, generating a column factory variable cross-section splicing node according to the cross-section size of the column in the column combination.

Specifically, the processor first determines whether the orientation information, the cross-sectional dimension, and the center point or the flange direction relative position of each column in the column combination meet preset conditions, and if the orientation information, the cross-sectional dimension, and the center point or the flange direction relative position of each column in the column combination meet preset conditions, generates a column factory variable cross-section splicing node according to the cross-sectional dimension of each column in the column combination.

Further, after the processor determines that the orientation information, the section size and the central point or the flange direction relative position of each column in the column combination meet preset conditions, connecting pieces of connecting nodes are selected according to the column type of the columns in the column combination, and then variable section splicing nodes of a column factory are generated according to the section size of the columns in the column combination and the selected connecting pieces.

Further, the processor may determine that the center point connection line of the adjacent columns in the column combination meets a preset condition of the center point, or that the column combination with the flanges of the adjacent columns aligned in the column combination meets the preset condition. And judging that the column combination in which the connecting line of the central points of the adjacent columns in the column combination does not meet the preset condition and the flange directions of the adjacent columns in the column combination are not aligned does not meet the preset condition. Alternatively, the preset condition may include whether the generated point connection is parallel to the z-axis of the coordinate system in the architectural design software. It should be clear that in building design, a coordinate system is typically preset, which includes an x-axis, a y-axis, and a z-axis, which is typically the axis perpendicular to the horizontal plane in the building design scenario.

According to the method for generating the variable cross-section splicing node of the column factory, the column in the design interface is identified by automatically acquiring the type of the element in the design interface, the generation position of the element and the attribute information of the element, then the column combination which possibly needs to be spliced is screened through adjacent information, the column combination which needs to be spliced is further screened through preset conditions, and finally the variable cross-section splicing node of the column factory is generated according to the cross-section size of the column in the column combination. According to the method, the column factory variable cross-section splicing node required in design software can be automatically generated without manually selecting the position of the connecting piece and setting parameters by a user.

And step S232, determining the placement position of the connecting center column according to the maximum web width and the center point or the flange of the column which needs to be sheared in the column combination.

Specifically, the processor determines the placement of the connecting center column based on the maximum web width and the center point or flange of the column in the column assembly that requires a shearing operation. Specifically, the column of the column combination to be subjected to the shearing operation may be determined according to the column type of the column. More specifically, when the column shape of the column in the column assembly is an H-shaped column, both the upper column and the lower column in the column assembly need to be sheared. When the column type of the column in the column combination is a box type column and a round type column, only the lower column in the column combination needs to be sheared.

Optionally, the processor determines the sheared lengths of the lower columns as the maximum web width plus a preset length; the processor determines the cut length of the upper column to be 1.5 times the maximum web width plus a preset length. Alternatively, the preset length may be 150 millimeters.

And step S2322a, performing shearing operation on the upper column and the lower column according to the shearing length, so that the top center point of the lower column is downwards moved by the shearing length, and the bottom center point of the upper column is upwards moved by the shearing length.

The column factory variable cross-section splicing node generated by the method of the embodiment ensures that the light steel body is firm, and can accord with the detailed construction drawings of steel structure nodes of multi-story and high-rise civil buildings, 16G519, steel structure design specifications, GB 50017-2017 and building structure load specifications, GB 5009-2012.

In one embodiment, step S220 may be implemented based on a preset neighbor algorithm. Specifically, the processor may calculate the neighboring information of the column through the neighboring algorithm, and then screen the column according to the neighboring information, to obtain a column combination.

In one embodiment, the adjacency algorithm is executed to process models (also known as solid models or model components, etc.) in architectural design software to obtain adjacency information between the models. Alternatively, the model may be a beam, column, or the like component in a building design software interface. The beam, column, etc. assemblies may be used in connection with the design of light gauge steel structures. As shown in fig. 14, the implementation of the above-mentioned adjacent algorithm specifically includes:

s11, acquiring target surface information of a target model; the target surface information is used for representing the pose of a target surface in a target model, and the target surface is one surface of the target model.

Specifically, the processor obtains target surface information (e.g., a flange surface of a column) of the target model, the target surface information being information about a target surface in the target model, wherein the target surface is one of a plurality of surfaces of the target model. It should be noted that, the target surface information may include, but is not limited to, a size, a shape, an orientation of the target surface, a relationship with the solid model, and the like, where the target surface information can represent a pose of the target surface.

S12, generating a virtual entity according to the target surface information; wherein one surface of the virtual entity matches the target surface.

Specifically, the processor may stretch or extend the target surface along a normal direction thereof according to the target surface information, so as to generate a virtual entity, and one surface of the virtual entity is matched with the target surface. It should be noted that, the virtual entity is generated along the target surface, where one surface is attached to the target surface, so that the surface of the virtual entity can be matched to the target surface, for example, the shape and size of the surface attached to the target surface in the virtual entity are matched to the target surface, further, the surface is consistent with the shape and size of the target surface, or the difference between the two is smaller than the preset range.

S13, determining the adjacent relation between the target model and the comparison model according to the intersecting state of the virtual entity and the comparison model, wherein the adjacent relation is the adjacent information.

Specifically, the processor may determine the intersection between the virtual entity and the other comparison model, thereby obtaining an intersection state of the virtual entity and the comparison model, and then determine, according to the intersection state of the virtual entity and the comparison model, an adjacent relationship between the target surface and the comparison model, and may determine an adjacent relationship between the target model and the comparison model. The comparison model may be a solid model that needs to perform adjacent relation judgment with the target model in other solid models besides the target model. It should be noted that the intersecting state may include intersecting and non-intersecting, where intersecting refers to that two solid models overlap in space, that is, collision occurs between the solid models, which does not conform to the actual situation. The above-mentioned adjacent relation may include adjacent and non-adjacent, and adjacent means that two solid models do not collide, and are relatively close to each other, and are two solid models that need to be connected or fixed.

In this embodiment, the processor may acquire target surface information of the target model, generate a virtual entity matching with the target surface according to the target surface information, and then determine an adjacent relationship between the target model and the comparison model according to an intersection state of the virtual entity and the comparison model. Because the target surface information is used for representing the pose of the target surface in the target model, and the target surface is one surface of the target model, the processor can automatically obtain the adjacent relation among a plurality of entity models based on the model surface information of the entity models by adopting the method in the embodiment, and further, the method is applied to the conditions of automatically generating connection nodes, automatically filling materials and the like, so that manual operation is further reduced, the problem of low efficiency and easiness in error caused by manual operation is avoided, and the method greatly improves the design efficiency and greatly improves the design accuracy. Meanwhile, the method greatly improves the degree of automation in the design process, further reduces the learning cost of designers, and further reduces the design cost.

Optionally, the target surface information includes a size of the target surface, a position of the target surface, and a normal to the target surface. In this embodiment, by the target surface information including the size of the target surface, the position of the target surface and the normal direction of the target surface, the target surface can be reasonably extended to obtain a virtual entity matched with the target surface, so that the adjacent relation between the target model and the comparison model can be obtained by intersecting and judging the virtual entity and the comparison model.

Alternatively, on the basis of the above embodiments, step S12 may specifically include: generating the virtual entity along the normal direction of the target surface according to the target surface information; and the surface of the virtual entity, which is perpendicular to the normal direction of the target surface, has the same size as the target surface, and the thickness of the virtual entity is used for representing the judgment threshold value of the adjacent relation. Specifically, the computer device may generate the virtual entity by stretching or stretching the target surface along a normal direction of the target surface according to the size of the target surface according to the target surface information. Based on this, the size of the surface perpendicular to the normal of the target surface in the generated virtual entity is the same as the size and shape of the target surface. The thickness of the virtual entity is not particularly limited in this embodiment, and may be set by using a judgment threshold of the adjacent relationship. For example, if more than X cm determines that the two solid models are not adjacent two solid models, and less than X cm determines that the two solid models are adjacent two solid models, the thickness of the virtual entity may be set to X cm. In this embodiment, according to the above target surface information, the computer device generates a virtual entity perpendicular to the target surface along the normal direction of the target surface, where the size of one surface is the same as that of the target surface, and the thickness of the virtual entity is the thickness of the judgment threshold value capable of representing the adjacent relationship, so that the adjacent relationship between the sum of the target model and the comparison model can be obtained through the result of intersection judgment between the virtual entity and the other comparison model.

Alternatively, before the step S13, as shown in fig. 15, the method may further include:

s131, obtaining the common outline of the virtual entity and the target model.

Specifically, the processor obtains the common outline of the virtual entity and the target model in the three-dimensional space, and the virtual entity and the target model are of a three-dimensional structure, and the virtual entity is attached to the target surface of the target model, so that the common outline is an integral outline, and is also of a three-dimensional structure in the three-dimensional space, and the interior of the common outline is filled by the target model and the virtual entity.

And S132, projecting the common outline and the outline of the comparison model to three directions in a three-dimensional space where the target model is located, and judging whether projections of the common outline and the outline of the comparison model in the three directions are overlapped or not to obtain a projection result.

Specifically, the three-dimensional space in which the target model is located includes three directions, the computer device projects the common outline and the outline of the comparison model in the three directions respectively, and then judges whether the projections of the common outline and the outline of the comparison model in each direction intersect, so as to obtain a projection result. Alternatively, the projection result may include projection intersections of all three directions, and may include projection intersections of only one direction and projection intersections of two directions.

S133, determining the intersecting state according to the projection result.

Specifically, the processor may determine the intersection states of the target model and the comparison model according to the projection result. Alternatively, this step may include: if the projection results are that projections in the three directions are overlapped, determining that the intersection states of the target model and the comparison model are intersection; and if the projection result is that projections in any one of the three directions are not overlapped, determining that the intersection states of the target model and the comparison model are disjoint.

In this embodiment, the computer device obtains the common outline of the virtual entity and the target model, projects the common outline and the outline of the comparison model to three directions in the three-dimensional space where the target model is located, then determines whether the projections of the common outline and the outline of the comparison model in the three directions overlap, and obtains a projection result, and finally determines the intersection state according to the projection result.

Alternatively, on the basis of the above embodiments, the step S13 may specifically include: if the intersecting state is intersecting, determining that the target model is adjacent to the comparison model; and if the intersecting state is disjoint, determining that the target model and the comparison model are not adjacent. In this embodiment, the computer device converts the relatively complex judgment of the adjacent relationship between the entity models into the judgment of the intersection relationship which is easy to be realized, so as to realize automatic judgment of the adjacent relationship based on the computer language.

Fig. 16 shows steps for implementing the adjacent algorithm proposed in another embodiment, which specifically includes:

s31, acquiring a first model set; wherein the first model set comprises at least one first model, and any first model comprises at least one target surface.

Specifically, the processor obtains the first model set, which may be that all the entity models in the design model are screened according to the model identifier of the entity model, or are screened according to the screening condition set by the designer, or are combined with the search relation between the entity models, and the entity model serving as the search reference is used as a model in the first model set, so that a part of entity models needing to judge the adjacent relation is used as the first model set. The first model set includes at least one first model, each first model including at least one target surface, the target surface being any one of the first models.

S32, acquiring a second model set; wherein the second set of models includes at least one second model.

Specifically, the processor obtains the second model set, which may be that all the entity models in the design model are screened according to the model identifier of the entity model, or are screened according to the screening condition set by the designer, or are combined with the search relation between the entity models, and other entity models corresponding to the reference entity model and needing to determine the adjacent relation are used as the models in the second model set, so that a part of the entity models needing to determine the adjacent relation are used as the first model set. The second set of models includes at least one second model.

Alternatively, the general adjacency is determined by looking up another model from one model, e.g., looking up a class B model from a class a model, then taking the class a model as the model in the first model set and the class B model as the model in the second model set. The first model set and the second model set have partial same entity models, but the first model and the second model selected in the process of adjacent judgment are different entity models. For example, when the adjacency relation between the wall keel model and the bottom guide beam model is judged, the wall keel model is taken as a model in a first model set, and the bottom guide beam model is taken as a model in a second model set. Of course, when the adjacent relation between the wall keel model and other entity models is determined, the strong keel model may be used as the entity model in the second model set, which is not limited to this embodiment.

S33, generating at least one virtual entity matched with each target surface according to target surface information of each target surface of each first model; the target surface information is used for representing the pose of a target surface in a target model, and one surface in the virtual entity is matched with the corresponding target surface.

Specifically, the processor may read the target surface information of each target surface of each first model, and since the target surface information can represent the pose of the target surface in the target model, the processor may respectively extend each target surface according to the pose of the target surface, so as to respectively generate at least one virtual entity matched with the target surface.

Specifically, the processor may determine an intersection state between each virtual entity and each second model, and summarize the intersection states between the plurality of virtual entities and the second model, thereby generating a set of adjacent states between the entity models in the first model set and the second model set.

In this embodiment, the processor obtains the first model set and the second model set, generates at least one virtual entity respectively matched with the target surface according to the target surface information of each target surface of each first model, and then generates the adjacent state set between the entity models in the first model set and the second model set according to the intersecting state of each virtual entity and each second model. Meanwhile, the method greatly improves the degree of automation in the design process, further reduces the learning cost of designers, and further reduces the design cost.

Alternatively, on the basis of the embodiment shown in fig. 16, one possible implementation manner of step S33 may include: generating at least one virtual entity along the normal direction of each target surface according to the target surface information of each target surface of each first model; the surface size of the virtual entity, which is perpendicular to the normal direction of the corresponding target surface, is the same as that of the corresponding target surface, and the thickness of the virtual entity is used for representing a judging threshold value of the adjacent relation. Specifically, the processor may extend or stretch the target surface along a normal direction of the target surface according to the size of the target surface, thereby generating the virtual entity. Based on this, the size of the cross section of the generated virtual entity perpendicular to the normal direction on the target surface is the same as the size and shape of the target surface. The thickness of the virtual entity is not particularly limited in this embodiment, and may be set by using a judgment threshold of the adjacent relationship. For example, if more than X cm determines that the two solid models are not adjacent two solid models, and less than X cm determines that the two solid models are adjacent two solid models, the thickness of the virtual entity may be set to X cm. In this embodiment, according to the target surface information of each target surface in each first model, the computer device generates, along the normal direction of the target surface, virtual entities having the same size as the target surface and perpendicular to the normal direction of the target surface, each virtual entity corresponding to one target surface, and the thickness of the virtual entity being a thickness capable of characterizing the judgment threshold of the adjacent relationship, so that the adjacent state set between the first model set and the second model set can be further obtained through the result of the intersection judgment between the virtual entity and the second model set. In this embodiment, the computer device converts the relatively complex judgment of the adjacent relationship between the entity models into the judgment of the intersection relationship which is easy to be realized, so as to realize automatic judgment of the adjacent relationship based on the computer language.

Optionally, the step S34 may further include, as shown in fig. 17:

s341, respectively acquiring the intersection states of each virtual entity and each second model, and generating an intersection state set.

S342, obtaining the adjacent state set according to the intersecting state set; wherein the adjacent state set comprises a plurality of adjacent value pairs, and each adjacent value pair is used for representing whether a first model and a second model are adjacent.

Specifically, the processor acquires the intersection states of each virtual entity and each second model respectively and performs statistics, so that an intersection state set between at least one virtual entity and at least one second model is generated. And then the computer equipment generates an adjacent state set between the first model and the second model, which are corresponding to the virtual entity, of the target surface according to the intersecting state set between the virtual entity and the second model. It should be noted that the above-mentioned adjacent state set includes a plurality of adjacent value pairs, and each adjacent value pair can represent whether a first model and a second model are adjacent. The first model tag and the second model tag correspond to a first model and a second model respectively, and the first model tag and the second model tag can be names, IDs, numbers or the like. For example: a neighboring value pair comprises a first model A and a second model B, and a neighboring value 1, and the neighboring value pair represents that the entity models A and B are neighboring; one neighbor pair includes a first model a and a second model B, and a neighbor value of 0, it can be characterized that the solid models a and B are not adjacent. And adopting a first model label, a second model label and adjacent values to form adjacent value pairs, wherein a plurality of adjacent value pairs form the adjacent state set.

Optionally, the adjacent value pair includes a first model tag, a second model tag and an adjacent value, and the adjacent value is used to characterize whether the first model represented by the first model tag and the second model represented by the second model tag are adjacent. By adopting the plurality of adjacent value pairs comprising the first model label, the second model label and the adjacent values of the first model label and the second model label, and representing the adjacent relation among the plurality of entity models by the adjacent relation set formed by the plurality of adjacent value pairs, the adjacent relation among the plurality of entity models can be expressed more clearly, the subsequent operation of automatic node placement, automatic filling and other automatic design based on the adjacent relation set is facilitated, and the design efficiency and the accuracy of the models are further improved.

In this embodiment, the computer device converts the relatively complex judgment of the adjacent relationship between the entity models into the judgment of the intersection relationship which is easy to be realized, so as to realize automatic judgment of the adjacent relationship based on the computer language.
