FIG. 1 is a flow chart of the detailed operation steps of a method for building clearance analysis based on BIM technology.
Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In the description of the present invention, it should be noted that, as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, their indicated orientations or positional relationships are based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" as appearing herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The invention mainly solves the technical problem of providing a building clear height analysis method based on a BIM technology, which utilizes the BIM technology to simulate pre-construction through BIM, analyzes the clear height of an area with narrow space, dense pipelines or high clear height requirement, automatically generates a clear height analysis report, quickly and visually locates an unreasonable position, finds a part which does not meet the clear height requirement function and the aesthetic requirement in advance, deeply optimizes the pipelines, avoids the later design change, shortens the construction period and saves the cost.
The technical solution of the present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1, a flow chart showing the specific operation steps of the method for analyzing the net height of a building based on the BIM technology of the present invention is shown, and the method for analyzing the net height of a building based on the BIM technology mainly comprises the following operation steps:
step S1: respectively creating three-dimensional BIM models of the building and the pipeline by using Autodesk Revit software;
step S2: integrating the created three-dimensional BIM model of the building and the pipeline in Autodesk Revit software, and importing the three-dimensional BIM model into Fuzor software;
step S3: setting clear height analysis data in Fuzor software, and selecting an analysis area;
step S4: and performing clear height analysis calculation on the analysis area by using the Fuzor software according to the clear height analysis data to obtain a position which does not meet the clear height requirement, and generating a clear height analysis report.
Further, in step S1, by respectively pouring the structure construction drawing and the pipeline construction drawing into the Autodesk review software, the Autodesk review software can be used to respectively draw a three-dimensional BIM model with a size equal to that of the original building and the original pipeline (i.e., 1: 1), so that the accuracy of an analysis object can be fully ensured, and the model clearance can be more visually displayed by using the BIM visualization.
Preferably, when creating the three-dimensional BIM model of the building and the pipeline, the three-dimensional model of the building and the pipeline is drawn in the coordinate system with the same base point position coordinates, so as to perform integration between models in different specialties in step S2, and the integration of models in different specialties using the Autodesk Revit software is the prior art and is not burdensome here. In addition, in modeling, each member in the three-dimensional BIM model of the building and the pipeline is respectively subjected to ID labeling. When the net height analysis report is generated at the later stage, the ID of the component which does not meet the net height requirement can be derived, and in addition, the net height analysis report can further comprise data such as the name of the component, the view corresponding to the component, the average clearance between the components and the minimum clearance between the components.
The Fuzor software comprises a plurality of functional blocks of VR, multi-person network cooperation, 4D construction simulation and 5D cost tracking. Navisthrocks, P6 or Microsoft schedules can be loaded directly into the Fuzor software, created in the Fuzor software, and machinery and workers can be added to simulate site placement and field logistics scenarios. And finally, 4D construction simulation and related BIM information can be checked in VR, so that management efficiency is improved, construction period is shortened, and cost is saved.
In addition, the real-time bidirectional synchronization with modeling software such as Revit, Archicad and the like is a unique breakthrough technology of Fuzor software, and the strong compatibility of the Fuzor software to a mainstream BIM model provides an integrated design environment for AEC professionals so as to realize the seamless docking of the workflow. Files with different formats such as Revit, Sketchup, FBX and the like are integrated in Fuzor software, then the complete project is viewed in 2D, 3D and VR modes, and the model is designed and optimized in Fuzor, so that high-quality design results are delivered finally.
Therefore, in step S2, the three-dimensional BIM model created by the Autodesk Revit software can be imported into the fuzr software by using the fuzr plug-in, which is a conventional technique and is not burdensome here.
After the three-dimensional BIM model which is integrated is imported into the Fuzor software, a free height analysis module carried in the Fuzor software is opened, a free height analysis command box appears, free height analysis data are set in the command box, and an analysis area is selected, wherein the free height analysis data comprise: an inspection height, wherein components with a clear height lower than the inspection height are defined as not meeting the clear height requirement; an initial distance defined as a minimum detection distance; a minimum threshold, defining that components with a net height below said minimum threshold are not detected.
Specifically, for example, 5m is input in a column of the checking height of the net height analysis command box, all the components with the net height lower than 5m in the selected analysis area are monitored, that is, the components do not meet the net height requirements, such as the floor height, the top layer pipeline height, the full-length vertical pipeline height and the like;
for another example, if 1.5m is entered in the column of the initial distance of the net height analysis command box, it is specified that net height monitoring is performed every 1.5m (horizontal) in the selected analysis area, so that the smaller the initial distance value, the finer the net height monitoring and the higher the accuracy.
Finally, referring to the minimum threshold, when 1m is input in the column of the minimum threshold of the net height analysis command box, it means that components with net heights lower than 1m are not monitored, because the components do not affect the overall net height, and the detection of the components can be ignored, so that the detection efficiency is improved.
After the input of the clear height analysis data and the analysis area in step S3 is completed, the software automatically calculates the clear height result by clicking the operation button on the Fuzor page, clicks the corresponding result, automatically switches the view to the corresponding component which does not meet the clear height requirement, gives the component ID, and generates the clear height analysis report.
After the clear height analysis report is obtained, unreasonable positions can be found in advance according to the report, the construction drawing of the structure or the pipeline is optimized, and construction is assisted. The Fuzor software and the Autodesk Revit software are linked, are modified in the Fuzor, and are correspondingly and automatically modified in the Revit, and the three-dimensional BIM model in the Fuzor software can be updated according to the three-dimensional BIM model of the structure or the pipeline which is reported by the clear height analysis, the clear height analysis calculation is carried out again, and the cycle is repeated for many times until all pipeline components meet the clear height requirement.
The invention utilizes the visualization and the simulation of the BIM technology, draws a three-dimensional informationized BIM model of the building and the pipeline before construction through the Autodesk Revit software, leads the model into the Fuzor software, utilizes the software clear height analysis module, analyzes the clear height of the building by setting clear height analysis parameters, automatically generates a clear height analysis report, finds the part which does not meet the clear height requirement function and the aesthetic requirement in advance, and carries out deep optimization on the pipeline, thereby avoiding the later design change, shortening the construction period and saving the cost.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; the modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention, and are all included in the scope of the present invention.
The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
