Description
Technical Field
The application relates to the technical field of computer aided design, in particular to a method, a device and computer equipment for reducing and correcting a member of a BIM (building information modeling) model.
Background
The BIM (Building Information Modeling) technique is widely used in engineering design and project management in recent years as a core part of engineering quantity calculation. At present, the BIM model is used by a designer for modeling, and then a construction cost worker calculates the construction cost according to the BIM model. If the construction personnel finds that the conditions of component overlapping, component deduction errors and the like which do not accord with the construction cost standard exist in the model, the model is returned to the designer for modification, and then the modified model is subjected to construction cost. The whole process may require designers to modify the model repeatedly, which not only consumes a lot of time and labor cost, but also may cause engineering delay.
In practical applications, the reasons why the BIM model does not meet the engineering cost standard are as follows: the first, in reality, BIM modeling and engineering costs are handled by two different stations or companies, and the modeling standards used by the two are different. The second type, BIM modeling and construction cost work are responsible for the same person, but the BIM modeling standard is different due to different construction cost standards of different regions. Thirdly, many companies establish their own engineering cost specifications or BIM modeling specifications, and modeling personnel are required to manually adjust the model according to the specifications on the rules of Revit default shearing or connection, so that omission is avoided.
However, the current process of reducing and correcting the BIM model component to make it meet the engineering cost standard is usually completed by a designer, which is not only inefficient, but also has accuracy affected by the professional level and state of the designer, and the finally derived model has poor quality, resulting in the calculation error of the subsequent engineering cost. Therefore, the prior art has the problems of low efficiency and poor accuracy.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present application provides a component deduction correction method for a BIM model, taking an execution subject as a terminal as an example, and the method may include the following steps:
step S1, responding to a component deduction correction instruction, and acquiring a target deduction rule selected by a user and all components to be corrected in an original BIM model.
Wherein, the member can be divided into a structural column, a building column, a structural wall, a building wall, a beam, a structural plate, a building plate and the like; the deduction rule may be an automatic deduction rule set for the deduction relationship between the above 7 kinds of components, and the automatic deduction rule may include 28 deduction relationships obtained by combining the 7 kinds of components with each other, so as to define a deduction execution order between the two components for realizing standardized automatic component deduction correction.
Specifically, the target deduction rule can be flexibly configured according to the engineering cost calculation specification, besides the adoption of the Chinese automatic deduction rule, the target deduction rule can be configured as an automatic deduction rule in Malaysia and England, and the target deduction rule can be flexibly expanded to an automatic deduction rule supporting the specification of other countries or regions, or an automatic deduction rule unique to a company. The target deduction rule may be composed of one or more of the following rules: the component with high concrete strength is a component for reducing the concrete strength, for example, when a structural column and a beam are intersected, the concrete strength is respectively a structural column C30 and a beam C35, according to the principle of priority of the concrete strength, the structural column is sheared by the beam, and only the beam is reserved at the intersection; the structural member is a subtractive building member; the deduction sequence of China is column > > plate > > beam > > wall, and the deduction sequence of other countries or regions is different from that of China, for example, when a structural column and the structural wall are intersected, the structural column shears the structural wall according to the Chinese rule, the structural column is only reserved at the intersection, and according to the English rule, the structural column is sheared by the structural wall, and the structural wall is only reserved at the intersection; if the components are the same type, the components with large volume are buckled with the components with small volume; the designed members are deducted before the designed members, for example, the design precedence order is compared with the value of a Globally Unique Identifier (GUID), the GUID of the designed member before is smaller than that of the designed member after, and the GUID of the designed member before is deducted by the member with smaller GUIID.
In specific implementation, for similar components, the deduction priority order can be set as follows:
structural column VS structural column: the concrete strength is firstly given priority, the volume is firstly given priority, and finally the design is firstly given priority.
Building column VS building column: first according to the size preference, and then according to the design preference.
Structure wall VS structure wall: the concrete strength is firstly given priority, the thickness is secondly given priority, and finally the design is firstly given priority.
Building wall VS building wall: first according to the thickness, and then according to the design.
Beam VS beam: the concrete strength is firstly given priority, the volume is firstly given priority, and finally the design is firstly given priority.
Structural panel VS structural panel: the concrete strength is firstly given priority, the thickness is secondly given priority, and finally the design is firstly given priority.
Building panel VS building panel: first according to the thickness, and then according to the design.
For different classes of components, the deduction priority order may be set as follows:
structural member VS building member: the structural member takes precedence.
Column beam wallboard priority: such as all of the same grade concrete, first the columns, then the slabs, then the beams, and finally the walls.
Assigning an attribute priority order: the concrete grade strength is high and priority.
In some embodiments of this embodiment, the component deduction correction instruction includes a target deduction rule identifier selected by a user from a plurality of candidate deduction rule identifiers, and a component identifier of each component to be corrected automatically selected from the original BIM model according to the target deduction rule identifier.
Step S1 may include: and responding to the component deduction correction instruction, acquiring a target deduction rule corresponding to the target deduction rule identification, and acquiring components corresponding to the component identifications of the components to be corrected respectively.
Specifically, the terminal may receive a component deduction correction instruction, obtain, from the received component deduction correction instruction, a target deduction rule identifier selected by a user from the multiple to-be-selected deduction rule identifiers, and extract, according to the target deduction rule identifier, a corresponding target deduction rule from a preset deduction rule database; meanwhile, the component identification of each component to be corrected is obtained from the component deduction correction command, and corresponding components, namely all components to be corrected, are extracted from the original BIM model according to the component identification of each component to be corrected.
In the above embodiment, the user can flexibly configure the deduction rule identifier and the component to be corrected, and generate the corresponding component deduction correction instruction after selecting the target deduction rule identifier and the component identifier of the component to be corrected, so that the problem of deduction errors between components can be automatically corrected without manual participation, and full-automatic correction is realized.
And S2, judging whether the correlation between any two components with the intersection relation in all the components to be corrected accords with a target deduction rule or not, and correcting the correlation between the two components when the correlation between the two components does not accord with the target deduction rule.
Wherein, the two components to be corrected can be the same kind of structural components, the same kind of building components or non-same kind of components.
Specifically, when the terminal determines that the correlation between the two components does not meet the target deduction rule, the target deduction rule may correct the correlation between the two components to be correct.
In specific implementation, the interrelationship of any two components having an intersection relationship may be overlapping or deducting, and the interrelationship of two components not meeting the target deduction rule may have two situations: one is the overlapping of the components and the other is the wrong deductive relationship between the components. Therefore, the step can detect the condition of the overlapping or error deduction of every two components, and realize the automatic correction of the overlapping error or error deduction.
And S3, after all the components which do not accord with the target deduction rule are corrected, outputting a target BIM model consisting of all the corrected components.
Wherein, the target BIM model is a corrected model and can be output to cost personnel for cost; because the components which do not accord with the target deduction rule are corrected, the construction cost standard is met.
The component deduction correction method for the BIM model provided in the above embodiment may be configured to respond to a component deduction correction instruction, and obtain a target deduction rule selected by a user and all components to be corrected in the original BIM model, where the target deduction rule may be a deduction rule determined based on a project cost standard; judging whether the interrelation of any two members with an intersection relation in all the members to be corrected accords with a target deduction rule or not, and correcting the interrelation of the two members when the interrelation of the two members does not accord with the target deduction rule; and after all the components which do not accord with the target deduction rule are corrected, outputting a target BIM model consisting of all the corrected components. The method can efficiently and accurately automatically correct the condition that the components in the original BIM model do not accord with the target deduction rule, thereby improving the quality of the output model.
Based on the foregoing embodiments, please refer to fig. 2, in some embodiments, the method may further include:
and S4, generating correction result information corresponding to the target BIM according to all corrected components, and sending the correction result information to the terminal equipment for display.
Wherein the correction result information includes a pre-correction volume amount, a post-correction volume amount, and a volume amount difference before and after correction for each member to be corrected. For example, the building column of RevitID297126 shears the building column of RevitID297127, and the volume of the building column of RevitID297126 is kept 1.17m 3 Keeping the original shape; the volume of the building column of RevitID297127 is from 1.17m 3 Instead, 0.74m3, the difference in variation was 0.53m3.
In specific implementation, after the automatic deduction correction of the component is finished, a window for displaying correction result information can be popped up, and the correction result information can include a list of components which have finished deduction and a list of components which have failed deduction. If the list of components which fail to be deducted does not appear after the method is executed, all the components after the correction are in accordance with the engineering cost standard.
In the embodiment, the method can provide a visual correction result by displaying the correction result information, so that a user can intuitively grasp the component information before and after correction.
In some embodiments, the two members are homogeneous structural members; at this time, the Chinese deduction rule can be selected as the target deduction rule, that is, the concrete strength grade is judged first, then the designated attribute is judged, and finally the design priority is judged.
Step S2 may comprise the steps of:
judging whether the correlation of the two similar structural members accords with a target deduction rule or not according to the concrete strength grade attribute values of the two similar structural members, and carrying out member deduction on the two similar structural members according to the concrete strength grade attribute values when the correlation does not accord with the target deduction rule.
Specifically, taking the intersection of the structural wall and the structural wall as an example, the automatic correction process is described in detail:
firstly, detecting the concrete strength grade attribute value of the structural wall, and giving priority to the concrete strength grade attribute value.
When the concrete strength grade attribute value of the component is not defined or assigned, the concrete strength grade attribute value is considered to be 0 by default, and the component is a component without the concrete strength grade attribute at the moment.
In the first case, when two structural walls have concrete strength grade attribute values and values different: (1) When the component with the large concrete strength grade attribute value shears the component with the small concrete strength grade attribute value, the concrete strength grade deduction rule is met, and the detection is finished; (2) When the component with the large concrete strength grade attribute value is overlapped with the component with the small concrete strength grade attribute value, the component is automatically corrected to be the component with the large concrete strength grade attribute value and the component with the small concrete strength grade attribute value without meeting the concrete strength grade deduction rule, and the volume of the component with the small concrete strength grade attribute value is displayed to be reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the component with the large concrete strength grade attribute value is sheared by the component with the small concrete strength grade attribute value, the component is automatically corrected to be the component with the large concrete strength grade attribute value and the component with the small concrete strength grade attribute value without conforming to the concrete strength grade deduction rule, the component with the large concrete strength grade attribute value is sheared, the volume of the component with the small concrete strength grade attribute value is displayed to be reduced (for example, the difference value of the original volume, the corrected volume and the volume is reduced from large), and the volume of the component with the large concrete strength grade attribute value is displayed to be increased (for example, the difference value of the original volume, the corrected volume and the volume is increased from small to large).
In the second case, when only one member in the two structural walls has the concrete strength grade attribute value (1) when a member without the concrete strength grade attribute is sheared by the concrete strength grade attribute member, the concrete strength grade deduction rule is met, and the detection is finished; (2) When a concrete strength grade attribute component is overlapped with a non-concrete strength grade attribute component, the component is automatically corrected to be a component with a concrete strength grade attribute value and a component without the concrete strength grade attribute value, and the volume of the component without the concrete strength grade attribute is reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the member with the concrete strength grade attribute is sheared by the member without the concrete strength grade attribute, the member without the concrete strength grade attribute is automatically corrected to be the member with the concrete strength grade attribute which is sheared by the member without the concrete strength grade attribute, the volume of the member without the concrete strength grade attribute is reduced (for example, the original volume, the corrected volume and the volume of the member are different from each other), and the volume of the member with the concrete strength grade attribute is increased (for example, the original volume, the corrected volume and the volume of the member are different from each other).
In the third situation, the two structural walls do not have concrete strength grade attribute values or the attribute values are the same, and the concrete strength logical detection is finished because the two structural walls cannot be distinguished through the concrete strength attribute values, and the next logical judgment is carried out, namely, the specified attribute values are adopted for judgment.
And when the mutual relation does not accord with the target deduction rule, carrying out component deduction on the two similar structural components according to the specified attribute value.
When two similar structural members are structural walls or structural plates, the specified attribute value is a thickness value; when the two similar structural members are structural columns or beams, the attribute values are designated as volume values.
Case where the wall thickness attribute values are not the same: when the concrete strength grade attribute value cannot be distinguished, the concrete strength grade attribute value is processed by the structure wall thickness large priority deduction logic. (1) When the structural wall with large wall thickness is cut into the structural wall with small wall thickness, the deduction rule of the Chinese building is met, and the detection is finished; (2) When the structural wall with large wall thickness and the structural wall with small wall thickness are overlapped, the structural wall with large wall thickness and the structural wall with small wall thickness are automatically corrected into the structural wall with large wall thickness and the structural wall with small wall thickness, and the volume of the structural wall with small wall thickness is displayed to be reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the structural wall with the large wall thickness is sheared by the structural wall with the small wall thickness, the Chinese building deduction rule is not met, the structural wall with the large wall thickness is automatically corrected to be the structural wall with the small wall thickness, the structural wall with the small wall thickness is displayed to be reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small), and the structural wall with the large wall thickness is increased (for example, the original volume, the corrected volume and the difference value of the volume from small to large).
Case where the wall thickness attribute values are the same: and when the concrete strength and the wall thickness attribute value cannot be distinguished, ending the concrete logic detection and entering the next logic judgment.
And when the specified attribute values of the two similar structural members are equal, judging whether the mutual relation accords with a target deduction rule or not according to the identification information of the two similar structural members, and when the mutual relation does not accord with the target deduction rule, carrying out member deduction on the two similar structural members according to the identification information.
In specific implementation, the terminal can detect the design priority sequence among the walls of the same type of structure, and the design priority of the walls of the same type of structure is given first.
When the concrete strength and the wall thickness attribute value cannot be distinguished, the structural wall is used for preferentially designing deduction logic to process. Specifically, (1) when the structural wall is designed after being sheared, the structural wall meets the building deduction rule, and the detection is finished; (2) When the first design structure wall and the second design structure wall are overlapped, the building deduction rule is not met, the first design structure wall is cut and then the design structure wall is automatically corrected, and the volume of the second design structure wall is reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the first design structure wall is sheared by the second design structure wall, the construction deduction rule is not met, the first design structure wall is automatically corrected to be the first design structure wall sheared and then the design structure wall, the volume of the second design structure wall is displayed to be smaller (for example, the difference value of the original volume, the corrected volume and the volume from large to small), and the volume of the first design structure wall is displayed to be larger (for example, the difference value of the original volume, the corrected volume and the volume from small to large).
In some embodiments, the two members are a same type of building member, e.g., a building wall and a building wall meeting.
Step S2 may comprise the steps of:
judging whether the correlation of the two similar building components accords with a target deduction rule or not according to the specified attribute values of the two similar building components, and carrying out component deduction on the two similar building components according to the specified attribute values when the correlation does not accord with the target deduction rule.
And when the specified attribute values of the two similar building components are equal, judging whether the mutual relation accords with a target deduction rule or not according to the identification information of the two similar building components, and when the mutual relation does not accord with the target deduction rule, carrying out component deduction on the two similar building components according to the identification information.
The embodiment can judge whether the same kind of building components meet the target deduction rule or not. For example: when the Chinese deduction rule is selected, the designated attribute value is judged first, and then the design priority is judged. The deduction logic is similar to that of the similar structural members in the above embodiments, except that the concrete strength grade attribute value of the structural member does not need to be judged, and for the specific steps, reference is made to the principle of the similar structural members in the above embodiments, and details are not described here.
In some embodiments, the two members are non-homogeneous members; specifically, taking the intersection of the structural column and the structural slab as an example, whether the structural column and the structural slab meet the target deduction rule or not is judged. For example: when the Chinese deduction rule is selected, whether the structural member exists or not is judged, then the strength grade of concrete is judged, the general deduction rule of the building is constructed next time, the same type is judged, and finally the design priority is judged.
Step S2 may include the steps of:
and when the first type attributes of the two non-homogeneous components are different, judging whether the mutual relation of the two non-homogeneous components accords with a target deduction rule or not according to the first type attributes of the two non-homogeneous components, and deducting the components of the two non-homogeneous components according to the first type attributes when the mutual relation does not accord with the target deduction rule.
Wherein the first type of attribute is a structural member or a building member.
Specifically, whether each member is a structural member is detected, and deduction is performed according to the priority of shearing the building members by the structural members.
In the case where two non-homogeneous elements are a structural element and a building element, the target deduction rule shears the building element for the structural element. (1) When the structural member shears the building member, the building deduction rule is met, and the detection is finished; (2) When the structural member and the building member are overlapped, the building member is automatically corrected to be the structural member to cut the building member and the volume of the building member is displayed to be reduced (for example, the original volume, the volume after correction and the difference value of the volume from large to small); (3) When the structural member is sheared by the structural member, the structural member is automatically corrected to be the structural member sheared structural member without conforming to the building deduction rule, the volume amount of the structural member is displayed to be small (for example, the difference value of the original volume amount, the corrected volume amount and the volume is changed from large to small), and the volume amount of the structural member is displayed to be large (for example, the difference value of the original volume amount, the corrected volume amount and the volume is changed from small to large).
Further, step S2 may further include the steps of:
when the first type attributes of the two non-homogeneous components are structural components, judging whether the mutual relation of the two non-homogeneous components accords with a target deduction rule or not according to the concrete strength grade attribute values of the two non-homogeneous components, and when the mutual relation does not accord with the target deduction rule, carrying out component deduction on the two non-homogeneous components according to the concrete strength grade attribute values.
In specific implementation, when two non-homogeneous members are structural members and different members, the concrete strength grade logic judgment is performed, the deduction logic is similar to the judgment and correction steps of the concrete strength grade attribute values of the homogeneous structural members in the embodiment, namely, the concrete strength grade attribute values are detected, and the priority is given according to the concrete strength grade attribute values, and the details are not repeated herein.
And when the mutual relationship does not accord with the target deduction rule, carrying out component deduction on the two non-homogeneous components according to the second type attribute.
Wherein the second type attribute is any one of a column, a slab, a beam, and a wall.
Specifically, the above steps may adopt the chinese building deduction rule: first the column, then the slab, then the beam, and finally the wall. If the structural columns and the structural plates meet, the structural columns shear the structural plates.
In specific implementation, two non-homogeneous members are structural members and different members without concrete strength grade attribute values or with equal concrete strength grade attribute values, and are processed by Chinese building deduction logic (firstly, a column, then a plate, then a beam and finally a wall). (1) When the structural column shears the structural slab, the deduction rule of the Chinese building is met, and the detection is finished; (2) When the structural column and the structural plate are overlapped, the structural column and the structural plate do not accord with the deduction rule of the Chinese building, the structural column is automatically corrected into the structural column shearing structural plate, and the volume of the structural plate is displayed to be reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the structural column is sheared by the structural slab, the structural column is automatically corrected to be the structural column sheared structural slab without conforming to the Chinese building deduction rule, and the volume of the structural slab is displayed to be reduced (for example, the difference value of the original volume, the corrected volume and the volume is reduced from large to small), and the volume of the structural column is displayed to be increased (for example, the difference value of the original volume, the corrected volume and the volume is increased from small to large).
And when the first type attributes of the two non-homogeneous components are building components, judging whether the mutual relation accords with a target deduction rule or not according to the second type attributes of the two non-homogeneous components, and when the mutual relation does not accord with the target deduction rule, carrying out component deduction on the two non-homogeneous components according to the second type attributes.
Specifically, the above steps may also adopt a chinese building deduction rule, and the implementation process is similar to the above processing steps using the chinese building deduction logic, for example: (1) When the building column cuts the building plate, the building deduction rule of China is met, and the detection is finished; (2) When the building column and the building plate are overlapped, the building column and the building plate are automatically corrected to be the building column shearing building plate when the building column and the building plate do not accord with the Chinese building deduction rule, and the volume of the building plate is displayed to be reduced (for example, the original volume, the corrected volume and the difference value of the volume from large to small); (3) When the building column is cut by the building plate, the building column is automatically corrected to be the building column cut building plate without conforming to the Chinese building deduction rule, and the display shows that the volume of the building plate body is reduced (for example, the difference value of the original volume, the corrected volume and the volume is reduced from large to small), and the volume of the building column is increased (for example, the difference value of the original volume, the corrected volume and the volume is increased from small to large).
In this embodiment, the target deduction rule provided by the method may include a deduction logic rule in the general building industry, or perform preferential deduction according to a specified attribute value (for example, an attribute value of a concrete strength grade, an attribute value of a thickness, or an attribute value of a volume) in combination with reality, so that the limitation of a single deduction logic relationship is avoided, and deduction and correction of the BIM model are more comprehensively achieved in consideration of various deduction influences. The method provided by the embodiment can comprehensively and efficiently find and automatically correct the deduction problem.
In specific implementation, the original BIM model may have a condition that three or more components intersect, and in this case, it may be determined whether each two components meet the target deduction rule, and the deduction logic of the method is consistent with the principle of the steps in the above embodiments, and is not described herein again.
