Embodiment Construction

[0019] The digital installation method of high-rise steel structures based on BIM and three-dimensional measurement will be further described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become clearer when combined with the abstract of the specification and the claims. It should be noted that all the drawings are in very simplified form and use inaccurate scales, and are only used to facilitate and clearly illustrate the implementation process of the present invention.

[0020] Combining the current implementation methods of BIM technology and figure 1 , the present invention is based on BIM and three-dimensional measuring high-rise steel structure digital installation method comprising the following steps:

[0021] Step 1. The third-party unit (BIM consulting company) uses BIM technology to build a BIM 3D digital model of the high-rise steel structure according to the construction drawings issued by t...

Abstract

The invention provides a digital installation method for a high-rise steel structure based on BIM and three-dimensional measurement. The method includes following steps: step 1, establishing a BIM three-dimensional digital model of the high-rise steel structure; step 2, installing a three-dimensional measuring system at the spot and measuring a point cloud model of a member; step 3, processing the point cloud model by a contrast system and calculating the maximum error in the contrast system; step 4, giving an instruction of an adjusting method for on-site installation if the maximum error Delta>Delta0; and step 5, anchoring the member if the on-site member position error satisfies the requirement so that accurate installation of the member of the high-rise steel structure is realized. According to the method, aiming to the characteristics of high structure and complicated space of high-rise steel, BIM and three-dimensional measurement technologies are employed, and on-site accurate installation of the steel structure is realized.

Description

technical field [0001] The invention relates to a high-rise steel structure digital installation technology, in particular to a high-rise steel structure digital installation method based on BIM and three-dimensional measurement. Background technique [0002] Research by relevant departments in the United States shows that the ineffective work in the construction industry is as high as (waste) 57%, while the figure in the manufacturing industry is 26%, a difference of 21%. It can be seen that the production efficiency of the construction industry is very low, and this kind of desire to greatly improve production efficiency will involve the transformation of construction industry technology. At the current stage, the only means to achieve this change is BIM technology, which is called the second revolution of the construction industry. [0003] BIM (Building Information Model) is the abbreviation of Building Information Model. In 1975, Chuck Eastman proposed the "Building De...
