BIM-based pre-assembling method for double-curved glass curtain wall

Abstract

The invention relates to a BIM-based pre-assembling method for a double-curved glass curtain wall. The method includes the following steps that three-dimensional models of glass curtain wall components are established according to a modeling standard; detailed glass curtain wall component drawings are guided out and numbered, and then processing and production are carried out; three-dimensional scanning is carried out on the processed glass curtain wall components, point cloud data are obtained, and three-dimensional point cloud models are established through the point cloud data; the three-dimensional point cloud models and the three-dimensional models are compared to obtain deviation values of glass curtain wall component solid bodies, and glass curtain wall component information is adjusted till the deviation values meet glass curtain wall standard requirements; and overall pre-assembling of the three-dimensional point cloud models meeting the requirements is simulated in Revit, accumulative errors in the assembling process are eliminated till the pre-assembled three-dimensional point cloud models are completely matched with the three-dimensional models, and then the glass curtain wall components are delivered out of a factory and delivered to a construction site for solid component installation. By means of the method, the problems that the double-curved glass curtain wall is large in field installation difficulty, low in installation efficiency and low in precision are solved.

Description

technical field [0001] The invention relates to a method for pre-assembling a glass curtain wall, in particular to a method for pre-assembling a hyperboloid glass curtain wall based on BIM. Background technique [0002] Glass curtain walls are divided into frame-supported glass curtain walls, point-supported glass curtain walls, and unitized glass curtain walls. [0003] Frame-supported glass curtain wall is a glass curtain wall supported by a metal frame around the glass panel. [0004] The point support glass curtain wall is a glass curtain wall composed of glass panels, point support devices and support structures. Its support structure forms include glass rib support, single steel or steel pipe support, truss support and tension rod cable system support structure. [0005] Unitized curtain wall refers to the building curtain wall that is made of various wall surfaces and supporting frames in the factory to form a complete basic unit of curtain wall structure, and is di...
