Deepened design method for building metal containment system based on BIM

Abstract

The invention relates to a deepened design method for a building metal containment system based on BIM. The deepened design method comprises the steps of: (1), checking whether a building skin model and a steel structure deepening model have conflicts or not; (2), providing the conflicts or list information, which does not accord with installation of the containment system, and adjusting the model; and (3), by utilizing software, automatically generating a building metal containment system deepening model through one key according to a rule. By means of the automatic modelling design method disclosed by the invention, the deepened design efficiency can be increased; and delicacy management of an obtained engineering quantity list can be easily realized.

Description

technical field [0001] The invention relates to the technical field of building information modeling, in particular to a BIM (Building Information Modeling, Building Information Modeling)-based method for deepening the design of building metal enclosure systems. Background technique [0002] The building metal maintenance system was introduced into our country from abroad in the 1980s. It started from industrial buildings, and then gradually spread to public civil buildings such as airports and exhibition centers. During the transition from industrial buildings to public civil buildings, the building performance index The requirements are getting higher and higher, and the architectural graphics are more avant-garde and novel, and the quality requirements for the layout are also higher. [0003] At present, there are some deficiencies in the design, production and construction of the metal maintenance system in China, mainly related to the insufficient depth and breadth of t...

Problems solved by technology

[0003] At present, there are some deficiencies in the design, production and construction of the metal maintenance system in China, mainly related to the insufficient depth and breadth of the design, which requires the second deepening design of the metal maintenance system manufacturer to make detailed connections with the main structure of the steel structure Nodes, considering various loads, moments of inertia of the manufacturer's plate section, and installation technical requirements, but the current design method is to use CAD plan drawings and detailed joint drawings, which are prone to incomplete consideration during the detailed design process and lack of technology during construction. Create waste and accident hazards

[0004] Therefore, there are the following problems in the process of deepening the design. First, the subjective judgment of the deepening designer to design the roof structure may not guarantee the optimal design in the extremely complex architectural form. At the same time, the traditional building metal envelope system design method Based on plane 2D drawings, it is difficult to express the hidden parts of the project in the process of detailed design, such as the irregular outline projected from the top of the building to the plane, and the roof in the metal enclosure system has a slope. Traditional 2D drawings When expressing the section, only the section at a specific position is expressed, and the detailed design at other positions will be missed. Therefore, the metal maintenance structure system cannot effectively cooperate with the steel structure. In reality, steel structure column members often occupy the outer enclosure. The structural space of the first floor and other conditions lead to rework or program changes during the construction process on site, which affects the efficiency of the overall design and construction

Moreover, in the existing conventional modeling methods, the workload is heavy and the efficiency is low
