Background technique
Existing steel construction curtain wall locating mounting method mostly uses greatly the mode of manual measurement building before installing curtain wall
The surface for building object carries out installation positioning, and part curtain wall locating mounting method also carries out subsidiary by means of level and total station
Positioning.And since overall appearance requirement of the modern architecture to building is higher and higher, often use a large amount of and intensive curtain wall cloth
Office, and also certain designs will be presented with variation in shape in conjunction with the structure in building in part curtain wall.This allows for above-mentioned
The old curtain wall installation method of tradition is difficult to meet new building demand, and the curtain wall location and installation of large stretch of blockette is according to people
Work measures or carries out subsidiary positioning by level and total station merely, can generate very when large area is intensively installed
Big error causes to perplex to construction party.Therefore, existing curtain wall installation location technology has been increasingly difficult to meet needs.
Summary of the invention
It, should the purpose of the present invention is realizing the steel construction curtain wall location and installation method for correcting error based on BIM 3 D laser scanning
Method can design curtain wall unit size in BIM software, and carry out simulation installation, to exclude in installation process it is possible that
Positioning is inaccurate, the problems such as colliding between curtain wall so that curtain wall more refines during the installation process.
The invention is realized by the following technical scheme: the steel construction curtain wall location and installation based on BIM 3 D laser scanning is entangled
Folk prescription method, the curtain wall location and installation method for correcting error the following steps are included:
S100 acquires the field data of civil engineering structure, and determines the three-dimensional coordinate of civil engineering structure origin；
Collected field data is imported in BIM software the threedimensional model for establishing civil engineering structure by S200；
S300 designs the model of single curtain wall unit in BIM software；
S400 simulates the installation of curtain wall using the model of single curtain wall unit on the threedimensional model of the civil engineering structure, sentences
Break with the presence or absence of collision between adjacent curtain wall unit, if so, return step S300；Otherwise, step S500 is executed；
S500 generates the coordinate of each curtain wall unit, and is mapped on civil engineering structure, according to the coordinate of each curtain wall unit
Curtain wall unit is installed on civil engineering structure.
Further, in step S500, specifically, first by the threedimensional model origin of civil engineering structure and the original of civil engineering structure
Point is overlapped, then the coordinate of each curtain wall unit is mapped on civil engineering structure.
Further, in step S300, specifically, design single curtain wall unit model, including size, absolute altitude,
Angle, node processing and thin portion structural information.
Further, before step S400 further include:
S350 marks off several curtain wall installing zones on the region that civil engineering structure needs to install curtain wall, according to the tendency of wall
Block.
Further, in step S100 and S600, the scanning of field data is carried out using three-dimensional laser scanner and is adopted
Collection.
Further, the three-dimensional laser scanner uses fixed or Backpack type.
The beneficial effects of the present invention are: the steel construction curtain wall positioning proposed by the present invention based on BIM 3 D laser scanning
Method for correcting error is installed, curtain wall unit size can be designed in BIM software, and carry out simulation installation, to exclude in installation process
It is possible that positioning is inaccurate, the problems such as colliding between curtain wall, the three-dimensional coordinate of curtain wall unit is finally mapped into real civil engineering
In structure so that the installation accuracy of curtain wall greatly improves, avoid Curtain Wall Design, installation site it is unreasonable, reduce the duration,
Cost is saved.
Detailed description of the invention
Fig. 1 is a kind of side of steel construction curtain wall location and installation method for correcting error based on BIM 3 D laser scanning of the invention
Method flow chart.
Specific embodiment
Technical solution in the embodiment of the present invention that following will be combined with the drawings in the embodiments of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
Shown in referring to Fig.1, the present invention provides the steel construction curtain wall location and installation correction sides based on BIM 3 D laser scanning
One embodiment of method, the curtain wall location and installation method for correcting error the following steps are included:
S100 acquires the field data of civil engineering structure, and determines the three-dimensional coordinate of civil engineering structure origin；
Collected field data is imported in BIM software the threedimensional model for establishing civil engineering structure by S200；
S300 designs the model of single curtain wall unit in BIM software；
S400 simulates the installation of curtain wall using the model of single curtain wall unit on the threedimensional model of the civil engineering structure, sentences
Break with the presence or absence of collision between adjacent curtain wall unit, if so, return step S300；Otherwise, step S500 is executed；
S500 generates the coordinate of each curtain wall unit, and is mapped on civil engineering structure, according to the coordinate of each curtain wall unit
Curtain wall is installed on civil engineering structure；
S600 acquires the field data for being equipped with the civil engineering structure of curtain wall again, and imports in BIM software and be mounted with curtain
The civil engineering structure threedimensional model of wall is compared, and the curtain wall unit for filtering out installation irregularity is reinstalled.
Referring to Fig.1 shown in, in the preferred embodiment of this part, specifically, first by the threedimensional model origin of civil engineering structure with
The origin of civil engineering structure is overlapped, then the coordinate of each curtain wall unit is mapped on civil engineering structure.
Shown in referring to Fig.1, in the preferred embodiment of this part, in step S300, specifically, the single curtain wall list of design

Block.
Specifically, curtain wall also has multi-panel therewith, in specific mould since modern architecture shape is changeable, structure is complicated
When quasi- installation, every one side needs individually processing, and every curtain wall unit used on one side is also as it may chance individually designed therewith, such as
Spherical curtain wall and the flat curtain to connect therewith, respective curtain wall unit are obviously different under normal circumstances, are being walked
When rapid S400, the curtain wall in different sides should also be as individually being judged.
And when civil engineering structure of the curtain wall threedimensional model into reality maps, each curtain wall unit not only needs mapping center
Coordinate should also optionally map its edge key inflection point coordinate, because curtain wall unit is not necessarily regular shape, in determination
After centre coordinate and crucial inflection point coordinate, the Installation posture of each curtain wall unit can be specified.
In the preferred embodiment of this part, in step S100 and S600, live number is carried out using three-dimensional laser scanner
According to scanning and acquisition.
