On-site decoration method based on BIM

Abstract

The invention provides a BIM-based on-site decoration method. The BIM-based on-site decoration method comprises the following steps: placing a positioning piece on a construction site; building a BIM model; acquiring a virtual datum line corresponding to the wall surface of the building structure main body; establishing a virtual axis network; obtaining the position relation between the positioning piece and the virtual axis net and the position relation between the positioning piece and the virtual datum line; making the to-be-paid-off spool net and the to-be-paid-off datum line in a building structure body in the building structure body on the construction site; and decorating the construction site according to the space between the scanning reference surface corresponding to the virtual reference line in the BIM model and the building structure main body wall surface corresponding to the virtual reference line. According to the method, the accurate mark positions of the to-be-paid-off spool net and the to-be-paid-off datum line on the construction site are obtained through the position relation between the positioning piece in the BIM model and the virtual axis net and the position relation between the positioning piece and the virtual datum line; and the virtual to-be-decorated objects are placed between the scanning reference surface and the wall surface of the building structure main body, and then one-to-one correspondence processing is performed on the construction site, so the attractive effect of the decorated building structure main body is ensured.

Description

technical field [0001] The invention relates to the technical field of building decoration construction, in particular to a BIM-based on-site decoration method. Background technique [0002] The traditional modeling method generally uses manual on-site measurement of the decoration scene before modeling. During the modeling process, the wall and the wall are perpendicular to each other by default, and the wall and the ground are also defaulted to the reference coordinate system. Each surface is set either parallel or vertical, which is the ideal modeling effect, where the reference coordinate system is the absolute coordinate system corresponding to ideal modeling. [0003] But in the actual scene, the relationship between the walls of the main body of the building structure is not necessarily absolutely vertical. If the virtual objects to be placed are placed in the modeled virtual model, the virtual objects to be placed can be tightly The wall of the virtual model is past...

[0003] But in the actual scene, the relationship between the walls of the main body of the building structure is not necessarily absolutely vertical. If the virtual objects to be placed are placed in the modeled virtual model, the virtual objects to be placed can be tightly The wall of the virtual model is pasted, but because there are various non-detachable raised structures on the wall of the main building structure in the actual scene, and the wall is not necessarily perpendicular to the wall, the objects to be placed in the actual scene cannot be placed. To achieve the placement effect of the virtual model will bring inconvenience to the subsequent decoration construction, which will affect the efficiency of decoration work
