BIM three-dimensional modeling calculation and super-heavy beam identification method

Abstract

The invention discloses a BIM (Building Information Modeling) three-dimensional modeling calculation and super-heavy beam identification method, which comprises the following steps of: determining a load combination and a subitem coefficient according to a specification and a standard to obtain a concentrated line load calculation formula; according to a concentrated line load calculation formula, performing assignment on any beam model by utilizing Revit software, and loading the assigned beam model into a project model for data coverage, so that all frame beams in the project model have concentrated line load attributes; after assignment is completed, a super-heavy beam filter being added to the view, the filtering condition being that the concentrated linear load is larger than or equal to 20 kN / m, pattern filling being conducted on the super-heavy beam filter, and super-heavy beam recognition being conducted; and in Revit software, adding a super-heavy beam filter to the view of each layer of planar graph, distinguishing colors, adding beam marks in annotations, deleting marks of non-super-heavy beams, and exporting a two-dimensional drawing. The problems that the error rate of an existing quantity calculation mode is high, the speed of a measurement and calculation method is low, and much manpower is needed can be solved.

Description

technical field [0001] The invention relates to the technical field of BIM, in particular to a method for BIM three-dimensional modeling calculation and identification of overweight beams. Background technique [0002] In recent years, it is not uncommon for major safety accidents to be caused by problems in the construction management process of overweight and super high support formwork. Therefore, how to control the construction quality and safety of overweight and overhigh support formwork projects has attracted the attention of the majority of construction industry peers. To avoid major quality and safety accidents in overweight and superhigh formwork projects, it is necessary to start from judging whether the formwork is overweight and superhigh, and then to the preparation of the construction plan and the implementation of the plan. All links need to be controlled. [0003] According to the "Regulations on the Safety Management of Highly Dangerous Partial Projects" J...
