Problems solved by technology

The main material that makes up the ventilation system and fire-fighting and smoke exhaust system is a large-volume air duct. However, due to many reasons in the design drawings of many projects, the design depth of large-scale air ducts often cannot meet the needs of construction, and further design needs to be carried out before construction.
Various systems and pipelines in the basement are intricate, and the pipelines are densely staggered. If a collision occurs during construction, there will be dismantling and rework, and even lead to re-modification of the design plan, which will not only waste materials, delay the construction period, but also increase the number of projects. cost

Abstract

The invention relates to the field of air pipe prefabrication and installation construction under a BIM model. The method comprises the steps: building a model, detecting model collision, optimizing the size and elevation, splitting the model, prefabricating and processing the air pipe in a factory, installing the air pipe in place, debugging a system and the like, so the production accuracy is improved. A three-dimensional model is used for splitting the size of each component, and computer data comparison is carried out, so the accuracy in production is effectively improved, and the rework phenomenon is avoided; the cost is saved; compared with a traditional air pipe on-site machining technology, factory machining is achieved, the size of the air pipe is controlled through a computer, and generation of waste during air pipe manufacturing is effectively controlled; the construction period is shortened; the air pipe is prefabricated in production and directly installed on site, the construction period is shortened; compared with a traditional construction technology, the time cost is saved, and the construction progress target is guaranteed; the construction site space is saved; the production areas do not need to be divided in construction areas, and the construction sites are saved; and installation and construction difficulties are reduced.

Description

technical field [0001] The invention relates to the field of prefabricated installation and construction of air ducts under the BIM model, in particular to a method for prefabricated installation and construction of large air ducts under the BIM model. Background technique [0002] With the rapid development of society, building basements have become an indispensable part of urban architecture. In cities, we often see basements with various functions, such as underground shopping malls, underground supermarkets, underground parking lots, etc. These basements save us A lot of ground space provides great convenience for our life. However, the basement is a relatively sealed environment, and its ventilation effect and fire and smoke exhaust system seriously affect the safety of the basement. Therefore, when designing the basement of a building, the basement ventilation system and fire and smoke exhaust system will be designed. The main material that makes up the ventilation sy...
