Embodiment 1

[0023] see figure 1 As shown, a method for detecting the size of a super large combined steel box-shaped steel column and a steel plate shear wall described in this embodiment includes the following steps:

[0024] 1. First of all, choose a solid and flat site as the 3D observation site, and there should be no vibration operations around the site. In order to facilitate the turning and shifting of components, the site should be within the working range of lifting equipment. In this example, the storage warehouse on one side of the large-scale component painting workshop is selected, and there is a hoisting crane on the upper part to assist in lifting and placing.

[0025] 2. After the hoisting and placement are stable, select key control points at the steel member corbels, beam-column connections, and vertical member connection points, and set reflective stickers on the control points. The reflective stickers are simple self-adhesive prisms. Since the total station used on ...

Abstract

The invention belongs to the technical field of constructional engineering and in particular relates to a size detection method of an ultra-large combined type steel-box-shaped steel column and a steel plate shear wall. The size detection method can be used for accurately and rapidly rechecking a node space size of a steel part so as to ensure the output quality of the steel part. A deviation condition of a multi-node complicated steel part of the steel part is intuitively reflected, correction work of factories is guided, groping and probing are reduced and labor hours are saved. Through observation and inspection of steel parts of the same type, an influence rule on a whole deformation tendency of the steel part by manufacturing procedures is obtained; in a subsequent steel part manufacturing process, evidences are provided for the improvement of a machining process, and manufacturing and machining precision is continuously improved, and time and labor are saved and material wastes are reduced. The molding quality of the steel part is continuously improved, the matching of field installation is coordinated, so that the steel part can be machined accurately in one time and reworking does not occur in field. The guarantee degree of a construction progress is improved, the approval of owners and each matched subcontract unit is won and the project is propelled smoothly.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a method for detecting the size of a super-large combined steel box-shaped steel column and a steel plate shear wall. Background technique [0002] In the process of manufacturing and installing large-scale steel structures, in order to speed up the progress of on-site installation, shorten the adjustment time when steel components are assembled. It is necessary to improve the dimensional quality of steel components leaving the factory. However, for increasingly complex steel member joints and huge steel member sizes, the traditional external dimension inspection methods are stretched. Conventional steel component size inspection methods mainly use traditional measuring tools such as steel rulers and squares to measure the line, straight-line distance, and angle between each connection port, and compare them with the flat design drawing. If the size deviation m...
