Computer simulation pre-assembly method of construction steel structure

Abstract

The invention relates to a pre-assembly method of a construction steel structure, in particular to a computer simulation pre-assembly method of the construction steel structure. The method comprises the following steps: drawing out a three-dimensional standard map of all members of a construction structure according to a design drawing through computer software and establishing a three-dimensional model drawing and a standard map library; using a 3D optical scanning measuring system to carry out three-dimensional raster scanning on the members, measuring the entity members, and introducing into a computer for obtaining a three-dimensional stereo image; using the computer software to process the measured entity members, and being compared with the three-dimensional model drawing for inspecting whether the members are qualified or not; using the actually measured members to carry out simulation assembly on the whole construction structure; finding out amount of deflection of connecting parts between the actually measured members and the simulation assembly members; and providing a member simulation assembly detection parameter report after the simulation assembly of the actually measured members is qualified, and guiding the installation and the field construction. The method has simple operation, can cover the full process of the member overall part of the construction steel structure, and has representativeness and guidance; and one-time development can be utilized repeatedly, and the waste of resources can be further avoided.

Description

Technical field: [0001] The invention relates to a pre-assembly method for building steel structures, in particular to a computer simulation pre-assembly method for building steel structure parts. Background technique: [0002] At present, the pre-assembly of building steel structures at home and abroad has been assembled by manual operation of actual components, which has the following disadvantages: [0003] (1) The pre-assembly of components is cumbersome and occupies a large area of ​​the assembly site. The three-dimensional assembly of different structures is very special. The upper and lower, left and right, and front and rear components of the building structure cannot be completely assembled in place, which brings great difficulty to the work, especially complex The measurement deviation of multi-angle component connection is large, the measurement accuracy is low, and the installation quality cannot be fully guaranteed. [0004] (2) Building structural parts are di...

[0003] (1) The pre-assembly of components is cumbersome and occupies a large area of ​​the assembly site. The three-dimensional assembly of different structures is very special. The upper and lower, left and right, and front and rear components of the building structure cannot be completely assembled in place, which brings great difficulty to the work, especially complex The measurement deviation of multi-angle component connection is large, the measurement accuracy is low, and the installation quality cannot be fully guaranteed

[0004] (2) Building structural parts are difficult to detect as a whole, and the results are poor in representativeness and guidance

[0005] (3) Completely manual operation, large error

[0006] (4) Do not reuse, waste manpower, material resources, financial resources and other resources
