Problems solved by technology

Reinforcement engineering is one of the cores of engineering projects. Traditionally, rebar is expressed through two-dimensional drawings, with low information integration, cumbersome technical disclosure, and failure to realize refined management of rebar, resulting in large cost loss and serious waste of rebar materials.
With the development of building information technology, the three-dimensional model of steel bar, as the digital carrier of refined management of steel bar engineering, has basically realized the information management of steel bar entities. There are deficiencies
At present, the information of steel bar cutting is basically reflected in the steel bar blanking table, which is only expressed in text tables, which cannot meet the visualization and informatization of material breaking nodes.
The specific performance is that 1) the position of the broken material node cannot be visualized in the 3D model; 2) the connection mode of the steel bar at the broken material node, such as lap joint, welding, screw connection, etc., cannot be effectively expressed

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, a materialized expression method of steel bar breaking node information specifically includes the following steps:

[0039] Step 1. Establish the bar centerline and obtain the bar length

[0040] Combined with the engineering drawings, draw the center line of the steel bar in the CAD software; the drawing method is to capture the center point of the two-dimensional graphic element of the steel bar along the length direction and connect it into the center line; import the center line drawing of the steel bar through the "Import CAD" command of the Insert tab of Revit into the Revit software; through the Revit "conversion line" function, the detail line attribute of the steel bar centerline is converted into the model line attribute, and then imported into Dynamo by the Select Model Elements module; the value of each steel bar...

Abstract

The invention discloses a reinforcing steel bar breakage node information materialized expression method, and the method comprises the steps: building a steel bar center line in CAD according to a steel bar two-dimensional drawing, importing a Revit platform, obtaining the length of a steel bar through a Dynamo node, and generating a target steel bar length array; establishing a reinforcing steel bar breakage optimization program package of the Python language; introducing a program package into a Py module of the Dynamo platform, and inputting a specification steel bar length and a target steel bar sequence array at the same time to generate a broken material node information data set; using the length of the steel bars along the data set as a positioning interval, creating a spherical geometry in each target steel bar and instantiating into a spherical entity family, meanwhile, giving node information parameters, and establishing a steel bar model with material breaking node information; according to the method, under the condition that the minimum steel bar consumption is guaranteed, the steel bar breakage data is associated with the node entity family, materialized expression of steel bar breakage node information is achieved, breakage information storage of the steel bar information model is perfected, and a new thought is conveniently provided for materialized expression of various virtual information of follow-up projects.

Description

technical field [0001] The invention belongs to the technical field of building information modeling (Building Information Modeling, BIM), and in particular relates to a materialized expression method of steel bar breaking node information. Background technique [0002] In recent years, the construction industry has used cloud computing, big data, Internet of Things, BIM and other technologies to gradually assist the refined design, construction and management of engineering projects.
