[0025] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of the present invention in any way.

[0026] Embodiment 1: A method for reviewing window detailed drawings based on BIM is disclosed, see Figure 1 , by adding parameters such as window category, audit content, audit elements, etc. to the window family in the form of family parameters, and assigning specific parameter values ​​to each window embodiment, and then using the detail table function to create an audit table, through the detail table function or reading the model, review the detailed drawings of the window, and finally intelligently display the audit conclusion; specifically including the following steps: S1. Classification: Classify windows according to their smoke prevention and exhaust methods, for example, natural ventilation windows and natural smoke exhaust windows; in BIM, add a project parameter named "Smoke Prevention and Exhaust Method", the specification is "Public", the parameter type is "Text", the parameter grouping method is "Text", and "Instance" is checked; and the parameter type is added to the instance properties of the window.

[0027] S2. Clarify the audit content: Identify and determine the smoke prevention and exhaust function indicators of the window, such as opening area, opening area, effective area, etc.; in BIM, add family parameters with the names "opening area, opening area, effective area", the specification is "public", the parameter type is "area", the parameter grouping method is "data", and check "type".

[0028] S3. Determine the audit elements: various factors associated with the smoke and exhaust function indicators of windows (including the window opening method, the location characteristics of smoke-proof windows, the location characteristics of smoke exhaust windows, etc.) are determined as audit elements, and the window opening method includes casement windows and hung windows; the location characteristics of smoke-proof windows include enclosed stairwells, smoke-proof stairwells, independent vestibules, fire elevator vestibules, refuge rooms, combined classrooms, and corridors; the location characteristics of smoke exhaust windows include smoke storage bins and non-smok storage bins; add project parameters with the name "Set Location", the procedure as "Public", the parameter type as "Text", the parameter grouping method as "Text", and check "Instance".

[0029] S4. Create window family: Use the "Metric Window" family template in Revit to create a window family. The style of the window family is designed by the architectural designer or detail designer. The specific steps include (see Figure 2-6 ): S41. Create a "window frame" family; S42. Create the "Window Sash" family and the "Littoral" family; S43. Nest the "window sash" family and the "light" family into the window family; S44. Draw reference planes, set dimensioning, and add control parameters to make the positions of the "window sash" family and the "light beam" family variable; S45. Establish a mapping relationship between the parameters "single window sash height" and "single window sash width" in the "window sash" family and the "light" family and the parameters "single window sash height" and "single window sash width" in the "window frame" family.

[0030] S5. Add parameters and parameter values: Add steps S1 to S3 to the BIM model as "parameters", and add the specific contents in steps S1 to S3 to the "parameters" as "parameter values"; Specifically, the parameters added by "project parameters" include "smoke and exhaust method, setting position, setting height, opening method", the parameters added by "family parameters" include "opening area, opening area, effective area", and the parameters added by "new parameters" include "whether qualified", select "yes / no" for parameter type, and select "analysis results" for parameter grouping; and add the "project parameters" in steps S1~S3 to "parameters" in the form of "parameter values". The specific method is: first load the created window family into the BIM model, and then add the parameter values ​​described in the design file to the "instance properties" of the model file; "family parameters" are directly calculated by formula, and "new parameters" are added by selection.

[0031] Specifically, the steps to add "parameters" include: S51. The audit parameters determined in step S4 are “customized” as “shared parameters”; S52. Use the "New Parameter" command in "Family Type" to add to the window family.

[0032] Specifically, the "project parameters" in steps S1 to S3 are added to the "parameters" in the form of "parameter values". The specific method of adding parameter values ​​is: the parameter values ​​of "smoke and exhaust method, setting location, setting height, and opening method" are entered directly for the first time, and are selected for non-first entry; the parameter values ​​of "opening area, opening area, and effective area" are automatically generated by the software by setting "formulas".

[0033] S6. Use the schedule function in Revit to create an audit table, and add the "parameter" added in step S5 as a "field" to the schedule (see Figure 7 ). Specifically include: S61. Add fields; the added fields include type mark, installation location, smoke control and exhaust method, opening area, opening area, and effective area; S62. Filter settings; filter condition is the field whose type tag contains "p"; S63. Grouping and sorting; select "Type Mark" for the first sorting method, and select "Smoke and exhaust method" for the second sorting method; S64. Format setting; set conditional formatting for the fields "opening area, opening area, effective area", where the "test" item selects "less than or equal to" according to the standard description, and the "value" item selects "the standard value set in the Technical Standard for Building Smoke Prevention and Exhaust Systems" according to the standard description, and the background color selects "red".

[0034] Based on the created audit form, the audit conclusion is intelligently output as "yes" or "no". This method can identify in advance the unclear expression problems of drawings due to cross-disciplinary issues, eliminate non-compliant items in time, reduce losses caused by rework, and effectively speed up the progress of fire protection acceptance.

[0035] Application Example 1: Taking a Youth Talent Apartment Academy Project as an example The Youth Talent Apartment Project is located in Zhengdong New District, Zhengzhou City. The project construction mode is an integrated "EPC + prefabrication + finished product delivery" project, consisting of 15 residential buildings, 10 supporting commercial and public service buildings, with a total construction area of ​​442,700 m 2 It has 2 underground floors, 3 partially underground floors, 26 above-ground floors, and a building height of 75.70m. The basement and 1-4 above-ground floors are cast-in-place shear wall structures, and 5-26 above-ground floors are prefabricated shear wall structures.

[0036] The method described in Example 1 is used to review the detailed drawings of the windows of the project, including: dividing the window categories according to the smoke and exhaust methods of the windows, wherein the number of windows is 9648 in total, and the number of smoke and exhaust windows is 2048. The smoke and exhaust function indicators of the windows are identified and determined as "opening area, opening area, and effective area". The window opening method, the location characteristics of the smoke and exhaust windows, and the location characteristics of the smoke and exhaust windows are determined as review factors. The window style designed by the architectural designer or the detailed designer is used to create a window family using the "Metric Window" family template in Revit. And the component information adding function in Revit is used to set parameters for all smoke and exhaust windows, and parameters such as "the functional room where the window is located, the smoke and exhaust method, the length, width, height and window frame thickness of the window" are added in the form of "project parameters"; "opening area, opening area, and effective area" are added in the form of "family parameters" and directly calculated in the form of formulas; according to the fire protection acceptance specification, for each functional smoke and exhaust acceptance standard, the parameter "whether qualified" is added in the form of "new parameters" in a selected manner, and the parameter type is selected as "yes / no", and the parameter grouping method is selected as "analysis results". The added "parameters" are treated as "fields" and added to the detailed list in Revit. Then, the detailed list function is used to create an audit form. Based on the created audit form, the audit conclusion is intelligently output as "yes" or "no", and it is intelligently determined whether the windows meet the requirements of fire inspection and acceptance.

[0037] Through the window detailed drawing review method, the project was systematically reviewed. 1,927 windows of a certain academy project of Youth Talent Apartment met the standard requirements, and 121 windows did not meet the standard requirements. After deepening the design of the unqualified windows, it was ensured that all windows met the fire protection acceptance standards. After practical application in the project, the review efficiency was improved by 68%, the review accuracy rate reached 100%, and the construction cost of the project was saved by 2.98 million yuan.

[0038] Application Example 2: Taking the Youth Talent Apartment Hui Mouyuan Project as an example The Youth Talent Apartment Hui Mouyuan project is located in a certain district of Zhengzhou City. The project construction mode is an integrated "EPC + prefabrication + finished product delivery" project, consisting of 20 residential buildings and supporting buildings, with a total construction area of ​​401,300 m 2 It has 2 underground floors, 3 partially underground floors, and 16 above-ground floors, with a building height of 46.81m. The basement and 1-3 above-ground floors are cast-in-place shear wall structures, and the 4-16 above-ground floors are prefabricated shear wall structures.

[0039] The method in Example 1 was applied to systematically review the window detailed drawings of the project. The number of windows that met the requirements in the Hui Mouyuan project of the Youth Talent Apartment was 3527, and the number of windows that did not meet the requirements was 709. After deepening the design of the unqualified windows, it was ensured that all windows met the fire acceptance standards, and rework caused by non-compliance with the acceptance specifications was eliminated. After practical application in the project, the efficiency of drawing review was improved by 72%, the accuracy of drawing review reached 100%, and the construction cost of the project was saved by 3.68 million yuan.

[0040] Application Example 3: Taking a primary school project in Zhengdong New District as an example The primary school project in Zhengdong New District includes a teaching building, an administrative office building and an underground garage. The teaching building is 24.45m high, the administrative office building is 16.05m high, and the total construction area is 26557.26m 2 , adopts frame structure design.

[0041] The smoke exhaust windows of the project were designed by an architect. Due to the cross-integration of professional knowledge, it is difficult for the architect to make an accurate description of the smoke exhaust function of the windows. The project was systematically audited using the window deepening drawing review method described in Example 1. In a primary school project in Zhengdong New District, the number of windows that met the requirements was 157, and the number of windows that did not meet the requirements was 30. After deepening the design of the unqualified windows, it was ensured that all windows met the fire inspection standards and passed the fire inspection smoothly. The practical application of the project improved the drawing review efficiency by 62%, the drawing review accuracy rate reached 100%, and saved 310,000 yuan in engineering construction costs.

[0042] Intelligent review of all BIM format drawings is carried out through the review method of window deepening drawings, which not only improves the review efficiency, but also ensures the safety and compliance of the project, laying a solid foundation for the subsequent project advancement.
