BIM-based air duct system prefabricating method

Abstract

The invention relates to a BIM-based air duct system prefabricating method, which comprises the following steps of constructing a multi-specialty design three-dimensional model based on a BIM technology; optimizing pipeline system arrangement of the multi-specialty design three-dimensional model to obtain a construction three-dimensional model; splitting from a pipeline system of the constructionthree-dimensional model to obtain a standard section air pipe model and a parameter section air pipe fitting model; according to the standard section air pipe model, a corresponding standard section air pipe is obtained through production, the standard section air pipe is installed on site, then space connection data needed by the parameter section air pipe fitting are obtained through on-site measurement, and therefore geometrical parameters of the parameter section air pipe fitting model are updated, and according to the updated parameter section air pipe fitting model, the parameter sectionair pipe fitting is obtained. Corresponding parameter section air pipe fittings are obtained through production. Compared with the prior art, the parameter section air pipe fitting matched with the on-site installation distance can be accurately machined. Therefore, the problem that a prefabricated air pipe system cannot be installed due to on-site operation and other construction errors is solved.

Description

technical field [0001] The invention relates to the technical field of air duct system prefabrication, in particular to a BIM-based air duct system prefabrication method. Background technique [0002] As an important part of mechanical and electrical engineering, air duct system is a piping system for air transportation and distribution. In order to ensure the efficient installation of mechanical and electrical engineering, it is often necessary to prefabricate the air duct system. However, with the rapid development of the current construction industry and the reduction of labor force, if there is not enough labor or the labor force cannot meet the installation project of the mechanical and electrical air duct system, At present, the application of construction industrialization technology is usually used to improve the efficiency of engineering installation and improve the quality of projects. [0003] Prefabricated technology is the direction of the engineering industry ...

AI Technical Summary

Problems solved by technology

[0003] Prefabricated technology is the direction of the engineering industry in recent years. The prefabricated air duct system technology has been widely used in China. However, in the popularization and application of prefabricated technology, the utilization rate of prefabricated air duct system is often caused by the factors of site construction errors. low

In general, the error of the prefabricated air duct system can not be installed. Air pipe fittings such as round places, and the factors that cause errors mainly include connection errors, positioning errors, and construction errors on the civil work surface, etc.
