Embodiment 1

[0026] A BIM optimization design method based on the special-shaped steel bars of the tunnel main structure, comprising the following steps:

[0027] (1) Importing the main structure model of the tunnel: the designer provides the two-dimensional CAD plan drawing of the main structure of the tunnel ( figure 1 Shown), on the basis of BIM software to establish a three-dimensional tunnel main structure model. Export the established tunnel main structure model in IFC format, import the IFC file into Planbar software, and use it as a carrier for post-reinforcement placement. The 3D tunnel main structure model is as follows: figure 2 shown;

[0028] (2) Create model view: through the create view command, select the corresponding perspective to create the view of the tunnel main structure model, including top view, cross-sectional view and side view (such as image 3 shown) to determine the rebar location during rebar placement. The steel bar number, size, spacing and position nee...

Abstract

The invention discloses a BIM optimization design method based on tunnel main structure special-shaped steel bars. The BIM optimization design method comprises the following steps: exporting a tunnel main structure model in an IFC format through BIM software and importing the tunnel main structure model into steel bar design software Planbar; creating a model view to determine the line shape of the tunnel main structure; extracting a model shell from the tunnel main body structure model, and normally deviating the distance of the thickness of the protective layer to determine the steel bar trend; segmenting the main body structure according to the distribution spacing of the reinforcing steel bars, and performing curve fitting through origin pro8.0; and generating and placing the reinforcing steel bars according to a command of generating the reinforcing steel bars by Planbar software according to a 3D line. The problem that the shape of the special-shaped steel bar is difficult to determine can be effectively solved, the design efficiency is improved, the design modification and auditing time is shortened, rework caused by inconformity of the steel bar size frequently occurring in the construction process is avoided, the steel bar machining precision is improved, and the construction period and cost are greatly saved.

Description

technical field [0001] The invention relates to the field of building structure design, in particular to a BIM optimization design method based on special-shaped steel bars of a tunnel main structure. Background technique [0002] Rebar is one of the most widely used materials in tunnel structures. Before pouring the concrete of the main structure of the tunnel, the steel bars must be made into a skeleton of a certain specification and form and loaded into the formwork. Since the steel bar shown in the structural construction drawing is the text information formed by the flat method, the concrete operation is to convert the text information of the steel bar into the physical steel bar information according to the flat law, and determine the blanking of the steel bar after considering the lap joint and anchorage according to the specification atlas Length, after the steel bar is processed to form a single steel bar entity of a specific shape and length, and then the single s...
