Detailed Description

A flowchart of a specific implementation of a BIM-based assembly rate calculation method provided by the present invention is shown in fig. 1, and the method includes:

step S101, receiving an assembly rate calculation instruction input by a user;

step S102, acquiring a corresponding preset BIM model of the building to be calculated and a preset assembly rate calculation formula according to the assembly rate calculation instruction;

specifically, in the project design process, data provided by developers, owners, design houses and factories can be imported into the information platform to generate a virtual three-dimensional BIM. BIM models of different types of buildings can be stored in the terminal. Due to the fact that the calculation modes of the assembly rates of different regions are different, the assembly rate calculation formulas of different regions can be preset at the terminal, and the assembly rate calculation formulas can be set according to the existing assembly type building identification standard.

When the assembly rate of the building needs to be calculated, an assembly rate calculation instruction can be input into an interface of the terminal, and the assembly type calculation instruction comprises a first identifier corresponding to the BIM model of the building to be calculated and a second identifier corresponding to the assembly rate calculation formula. The first identifier may be a number identifier, for example, the number "one" corresponds to the BIM model of the first building project, and the number "two" corresponds to the BIM model of the second building project; the second identifier is a geographical identifier, for example, "Hunan" corresponds to a preset assembly rate calculation formula in Hunan, and "Shanghai" corresponds to an assembly rate calculation formula in Shanghai. If the user inputs 'one' or 'Hunan' into the terminal, the terminal obtains the assembly rate of the first building project stored in the terminal by using the assembly rate calculation formula corresponding to the Hunan area, so that the terminal obtains the BIM model and the assembly rate calculation formula of the corresponding building to be calculated according to the instruction.

Specifically, referring to fig. 2, fig. 2 is a schematic flowchart illustrating another embodiment of the BIM-based assembly ratio calculating method according to the present invention, wherein step S102 includes:

step S1021, obtaining a corresponding preset BIM model of the building to be calculated according to the first identifier;

step S1022, obtaining a corresponding preset assembly rate calculation formula according to the second identifier.

Specifically, after the assembly type calculation instruction is obtained, a first identifier and a second identifier are obtained through analysis, and a corresponding preset Building Information Model (BIM) of the building to be calculated is searched and obtained in a database according to the first identifier; and searching in a database according to the second identifier to obtain a corresponding preset assembly rate calculation formula.

Step S103, obtaining a calculation index of the building to be calculated according to the assembly rate calculation formula;

after obtaining the assembly rate calculation formula of the building to be calculated, the calculation index can be obtained according to the assembly rate calculation formula, for example, when the assembly rate calculation formula isWhen, the calculation index is Q₁、Q₂、Q₃、Q₄，Q₁Is a major structural index, Q₂As indicators of enclosure walls and interior partition walls, Q₃Fitment and Equipment pipeline indices, Q₄Indexes lacking in the item are evaluated. For example, there are no kitchen and heating lines in public buildings. When the assembly rate meterWhen the calculation formula is p ═ (simple proportion X weight coefficient) X100%, the simple proportion and the weight coefficient are calculation indexes.

Step S104, obtaining corresponding prefabricated assembly information according to the BIM and the calculation index;

the BIM model of the building to be calculated is analyzed, and prefabricated assembly information of the building to be calculated can be obtained, wherein the prefabricated assembly information of the building to be calculated comprises but is not limited to the volume, the horizontal projection area, the stereoscopic projection area, the horizontal projection length and the stereoscopic projection height which respectively correspond to the member and the prefabricated part of the member. Because the assembly rate calculation formulas of different regions are different and the corresponding calculation indexes are different, the prefabricated assembly information required to be acquired is different, and therefore, after the calculation indexes are acquired, the corresponding prefabricated assembly information can be acquired according to the BIM model and the calculation indexes. For example, the required prefabricated information may be the volume of the prefabricated part and the total volume in the main structure vertical member; the total horizontal projection area of the prefabricated assembly beam, the prefabricated assembly plate, the prefabricated assembly and the prefabricated assembly.

Step S105, determining the score of the calculation index according to the prefabricated assembly information;

specifically, an assembly building score table may be preset in the terminal, after the prefabricated assembly information corresponding to the calculation index is obtained, each application proportion may be obtained by calculation according to the prefabricated assembly information, and then the score corresponding to the calculation index may be determined according to the assembly building score table according to the application proportion obtained by calculation. In an embodiment, a correspondence table between the application ratios and the evaluation scores/weighting coefficients may be set, and after each application ratio is calculated, the terminal may determine the corresponding evaluation scores/weighting coefficients according to the correspondence table. In another embodiment, after calculating the application proportions, the application proportions may be displayed so that the technician inputs the corresponding evaluation score/weighting factor based on the fabricated building score table.

And step S106, substituting the score of the calculation index into the assembly rate calculation formula to calculate and obtain the assembly rate.

After the scores corresponding to the calculation indexes are obtained, the scores are substituted into an assembly rate calculation formula, and the assembly rate can be accurately calculated.

According to the technical scheme, after the design of a building project scheme is finished, according to an assembly rate calculation instruction input by a user, a preset BIM model of a building to be calculated and a preset assembly rate calculation formula can be obtained, then a calculation index and corresponding prefabricated assembly information are determined, and then a value of the corresponding calculation index is determined according to the prefabricated assembly information; and substituting the score of the calculation index into an assembly rate calculation formula to calculate and obtain the assembly rate. The invention can calculate the assembly rate of the building project based on the BIM technology in the design stage of the building project, and improves the acquisition efficiency and accuracy of the assembly rate of the building project, thereby ensuring the feasibility of the building project.

In addition, referring to fig. 3, fig. 3 is a schematic flowchart illustrating a process of calculating a BIM-based assembly ratio according to another embodiment of the present invention, wherein step S104 includes:

step S1041, obtaining drawing information of each component of the building to be calculated according to the BIM model;

and step S1042, obtaining corresponding prefabricated assembly information according to the calculation indexes and the drawing information of each component.

Specifically, after the BIM model of the building to be calculated is obtained, the drawing information of each component of the building to be calculated can be obtained by analyzing the BIM model, and then the corresponding prefabricated assembly information can be obtained according to the calculation index and the drawing information of each component.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a BIM-based assembly rate calculating method according to another embodiment of the present invention, and step S106 is followed by:

and S107, sending out prompt information when the assembly rate is lower than a preset standard value, and displaying the difference value between the assembly rate and the standard value on a terminal interface.

Specifically, a standard value of the assembly rate can be preset at the terminal, and the construction project conforms to the assembly type construction approval standard only when the assembly rate is greater than or equal to the standard value. After the assembly rate of the building is obtained through calculation, the assembly rate can be compared with the standard value, and when the assembly rate of the building is lower than the preset standard value, the terminal sends prompt information to prompt a designer to adjust the design scheme. In a preferred embodiment, the terminal can also display the difference value between the assembly rate and the standard value on a terminal interface, so that the adjustment by a designer is more convenient. In another preferred embodiment, the score of the calculation index can be displayed on a terminal interface, so that the designer can know which calculation indexes do not reach the standard.

In addition, before step S101, the method further includes: acquiring a structure construction drawing and a building construction drawing of a building to be calculated; and generating a corresponding three-dimensional BIM (building information modeling) according to the structure construction drawing and the building construction drawing information. Specifically, in the early stage of design, the three-dimensional BIM model can be generated according to a structural construction drawing, a building construction drawing and the like provided by a developer, a design institute and a factory. In the design process, the three-dimensional BIM model can be adjusted according to parameters such as site construction, component transportation, factory production, project cost and the like.
