Abstract

The invention belongs to the technical field of buildings, and discloses a BIM technology-based external hanging plate construction method of an integrally assembled building, which comprises the steps of collecting construction video data of an external hanging plate of a building, construction weather data of the external hanging plate of the building and construction material data of the external hanging plate of the building; constructing a building model; rendering an external hanging plate of the building model; selecting the optimal appearance of the external hanging plate of accordingto rendering effect; using a positioning mechanism for positioning the external hanging plate for building assembly assembling the external hanging plate of the building by utilizing an assembling mechanism; and calculating the construction amount of the external hanging plate of the building by utilizing a calculation program. According to the invention, through a building model construction module, the method has relatively high data production efficiency and relatively small model data volume, and a generated three-dimensional model is relatively high in accuracy; and meanwhile, various complex special-shaped component parameters can be calculated through an engineering quantity calculation module, and engineering quantity precision is enough to meet the actual working requirements.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a construction method for an external hanging panel of an integrally assembled building based on BIM technology. Background technique [0002] The external wall hanging board is a construction method, which is to hang the board on the outside of the wall by dry hanging and other construction methods to achieve decoration or heat preservation effects. From the product point of view, the external wall hanging board is a kind of building material, which is a building board used for the external wall. External wall hanging panels must have basic properties such as corrosion resistance, high temperature resistance, aging resistance, no radiation, fire prevention, insect resistance, and no deformation. At the same time, they must also have beautiful appearance, simple construction, environmental protection and energy saving. Common exterior wall hanging boards include...
