Problems solved by technology

[0003] The object of the present invention is a detection method for steel structure components designed for the deficiencies in the prior art. It uses measured data to establish a three-dimensional line model of the component to match the original design model, and then measures the distance between corresponding points to judge the components at each site. Whether the interface meets the design requirements solves the inspection problem of complex components, the measurement time is short, the detection cost is low, and the detection accuracy of the components is greatly improved

Embodiment 1

[0021] The present invention further illustrates the data information inspection method of the steel structure member by detecting one of the lower chord members in combination with the three-zone ring-belt truss of the Shanghai Center Building under construction. The specific steps are as follows:

[0022] 1. Establishment of design model

[0023] In the 3D model of the three-zone ring-belt truss designed by Tekla Structures software, "explode" the part of the lower chord member made with the node attribute, hold down the "Alt" key and click any part in the lower chord member, that is Select all parts of the component, and then click the "File" menu - "Export" - "3D DWG" to output in the form of "surface", and store the bottom chord component as a three-dimensional "DWG" format solid design model.

[0024] 2. Make the detection form of the component

[0025] See attached figure 1 , the lower chord member of the design model is provided with three field interface ports of in...

Abstract

The invention discloses a detection method for a steel structure member. The method is characterized in that: a detected member is actually measured by using an electronic total station to establish a three-dimensional line model matched with a design model; and the distance between corresponding points is measured to check whether each field interface meets a design requirement. The method comprises the following specific detection steps of: establishing a design model and a three-dimensional line model; measuring the distance between corresponding points; and correcting the member. Compared with the prior art, the detection method has the advantages of high detection accuracy, low cost, capability of solving the inspection problem of a complex member, convenience for detecting and short measuring time.

Description

technical field [0001] The invention relates to the technical field of steel structure manufacturing, in particular to a steel structure member detection method for checking whether the processing accuracy of the member meets the design requirements. Background technique [0002] At present, in the steel structure processing industry, common methods such as squares, steel rulers, guy wires, lofting wires, and inspection templates are generally used to check whether the completed components can meet the design requirements. Today's steel structure modeling has become very complicated. The field interface of many components and the body are at a certain spatial angle, and the body and field interface of many components are in a state of spatial bending and torsion, which increases the inspection of steel components. There are many difficulties. With the existing detection methods, it is necessary to set up the ground sample and set up the detection tire frame, and then lift th...
