Problems solved by technology

[0004] However, due to the complex factors to be considered in the integrated wiring of various electrical categories, and the extremely large workload of cable and wire layout, there are few projects to fully simulate in BIM modeling, and generally only the bridge network of the route
This makes the construction, measurement and acceptance of cables difficult to find, forming a big gap in project quality and cost management

Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, the intelligent wiring method of BIM cable tray based on the inventory table; the steps are as follows:

[0040] Step 1. Import the cable inventory table, including cable number information, starting point device information, end point device information, and cable specification information;

[0041] Step 2. Selection and configuration of piping and bridges, configuration of specification and size information of extension bridges / conduits;

[0042] Step 3. System classification style configuration, set each system under the installation engineering specialty corresponding to the cable number, and the corresponding system color style, which is used to distinguish between systems when the cable is automatically created and drawn;

[0043] Step 4, analyzing the cable inventory table, and analyzing the cable number information, starting device information, terminal device information, cable specification information and estimated l...

Embodiment 2

[0072] The cable tray wiring of the BIM model of a certain subway project, this project is a subway platform installation project, the specific steps are as follows:

[0073] In order to achieve the above object, the present invention adopts the following technical solutions:

[0074] Step 1. Import the cable inventory table, including the secondary cable system information of 17 loops in the environmental control room.

[0075] Step 2. Selection and configuration of piping and bridges, and configuration of specifications and sizes of extension bridges / conduits.

[0076] Further, step 2 includes:

[0077] Step 2.1. Create a single selection table. For example, the approximate outer diameter of the WDZB-BYJ-5x6 cable is 17.1mm, the approximate cross section is 229.54mm2, and the corresponding piping selection is galvanized steel pipe sc32;

[0078] Step 2.2. Create a combination selection table. If the upper limit of the cross-sectional area exceeds 10000mm2, select a trough ...

Abstract

The invention discloses a BIM cable bridge intelligent wiring method based on an inventory table. The method comprises the following steps: 1, importing a cable inventory table; 2, performing model selection configuration on piping and a bridge frame: configuring specification and dimension information of the bridge frame / line pipe of the extension section; 3, performing system classification style configuration: setting systems under the installation engineering specialty corresponding to the cable numbers and corresponding system color styles for distinguishing the systems during automatic cable creation and drawing; 4, analyzing the cable inventory table; 5, analyzing the bridge network, searching the bridge network through which the cable passes, and calculating the path information of the cable lead-in / lead-out point and the extension section bridge / line pipe; 6, calculating cable paths, and finally determining all paths and then calculating the placement sequence of the cable on the bridge; 7, creating a cable; and 8, creating an extension section bridge frame / line pipe. According to the invention, the space design of the electrical pipeline becomes feasible, and the construction and metering work can be based on the basis.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to an intelligent wiring method for BIM cable trays based on an inventory table. Background technique [0002] The electrical pipelines and pipelines in the mechanical equipment installation project are similar to the intricate blood vessels covering the entire project, connecting the equipment and appliances in each area so that they can maintain normal operation. [0003] In practical applications, the air ducts and water pipes are usually more complete in the drawings, while the cables and wires in the field of strong and weak currents basically have no plan, only the main strong and weak current bridge plan and electrical system diagram. [0004] However, due to the complex factors to be considered in the integrated wiring of various electrical categories, and the extremely large workload of cable and wire layout, there are few projects to fully simulate during BIM...
