Abstract

The invention discloses a method for manufacturing and mounting an irregular abnormally-shaped large space steel structure, and belongs to the technical field of manufacturing of metallurgy and construction. The method for manufacturing and mounting the irregular abnormally-shaped large space steel structure is high in manufacturing and mounting quality and low in labor intensity and is convenient to operate. The method for manufacturing and mounting the steel structure comprises the following steps of: according to structural characteristics of a large number of nodes in the irregular abnormally-shaped large space steel structure, detaching the irregular abnormally-shaped large space steel structure into a plurality of steel structure manufacturing units; marking a node on the end part of each steel structure manufacturing unit as a measurement coordinate control point; projecting to a horizontal ground at the mounting position of the irregular abnormally-shaped large space steel structure to form the measurement coordinate control point; and controlling and measuring the central line and the scale height of each steel structure manufacturing unit by using a laser marked line distance measuring instrument arranged on the horizontal ground to ensure the mounting quality of the irregular abnormally-shaped large space steel structure. By the method, the cost is saved, and construction periods are shortened.

Description

technical field [0001] The invention relates to a manufacturing and installing method of a steel structure, in particular to a manufacturing and installing method of an irregular special-shaped large-space steel structure, which belongs to the technical fields of metallurgy and building production and manufacturing. Background technique [0002] As we all know, in the metallurgical industry and construction industry, steel structures mostly appear as regular components, and they are installed horizontally and vertically, with reference objects, easy-to-mark installation control lines, and easy to support and control during installation. At present, the construction design of large-scale venues in urban construction is novel, and many special-shaped steel structures are used as the structural skeleton, which poses many difficulties in production and installation for construction companies: such as large structures, irregular curved shapes in space, no reference objects during ...
