Line type verifying method and line type correction method of steel structure

Abstract

The invention relates to a line type verifying method of a steel structure. The method comprises the following steps that 1, in the modeling process of the steel structure, at least one straight linesection is designed on a steel structure model in advance, and two end points of each straight line section are recorded; 2, in the blanking process, the straight line sections are manufactured on thesurface of the steel structure in a sprayed manner; and 3, after blanking is completed, a pull line is placed between the two end points and pulled straightly, the pull line and the straight line section corresponding to the two end points are compared, and verifying of the line type of the steel structure is completed, wherein when the pull line and the straight line section coincide, the line type of the steel structure is unchanged, and when the pull line and the straight line section deviate, the line type of the steel structure changes. According to the line type verifying method and line type correction method of the steel structure, the line type of the steel structure such as a T-shaped profile web or slab deforming easily can be verified and corrected conveniently.

Description

technical field [0001] The invention relates to the field of line type verification and correction of steel structures, in particular to a line type inspection method and a line type correction method of a steel structure. Background technique [0002] The structure of the ship is complex, and a large number of horizontal and vertical structures have certain line types, which directly determine the line type of the entire hull. Especially for the transverse strong ribs and longitudinal girder structures, they are prone to deformation during blanking and construction. [0003] In the past, when the structural line type changed, it could only be found when the structure was assembled that it did not match the line type of the outer plate, or even could not be found. Moreover, it was troublesome to correct the structural line type. It was necessary to spray the accurate line type on the steel plate. Then correct the structure according to the line type. Therefore, the linear ...

Especially for the transverse strong ribs and longitudinal girder structures, they are prone to deformation during blanking and construction

[0003] In the past, when the structural line type changed, it could only be found when the structure was assembled that it did not match the line type of the outer plate, or even could not be found. Moreover, it was troublesome to correct the structural line type. It was necessary to spray the accurate line type on the steel plate. Then correct the structure according to the line type

Therefore, the linear deformation of planar structures such as strong ribs and strong longitudinal trusses cannot be detected in time, affecting the accuracy of structural linearity, and the correction process is difficult, increasing production costs
