Echelon mounting method of oversized plane multi-layer steel truss electronic workshop steel structure

Abstract

The invention discloses an echelon mounting method of an oversized plane multi-layer steel truss electronic workshop steel structure. The echelon mounting method comprises the following steps that (1), division of a plane hoisting area and a hoisting unit is conducted, specifically, hoisting equipment is selected according to the maximum weight of a hoisting component, construction areas are divided according to the rotating radius of the hoisting equipment, construction is conducted simultaneously in the longitudinal direction from the middles of the construction areas; (2), a first section of frame column is mounted in each construction unit in each construction area; (3), second section of frame columns and third to fourth layers of main steel trusses and third to fourth layers of secondary steel trusses corresponding to the second section of frame columns are mounted; (4) a third layer of main beams, a third layer of secondary beams, a fourth layer of main beams and a fourth layerof secondary beams are mounted; (5), third section of frame columns and fifth to sixth layers of main steel trusses and fifth to sixth layers of secondary steel trusses are mounted; (6), a fifth layerof secondary beams and a sixth layer of secondary beams are mounted; and (7), a fifth layer of hoisting keels and a sixth layer of purlines are mounted, and accordingly mounting of the oversized plane multi-layer steel truss electronic workshop steel structure is completed.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and in particular relates to a step-by-step installation method for the steel structure of a super-large plane multi-layer steel truss electronic factory building. Background technique [0002] With the development of the construction industry, steel structures have begun to be used in large-scale electronic industrial plants. The electronic industrial plant has the characteristics of super large plane, high height, and tight construction period. The construction method of steel structure electronic industrial plant is to seek safe, fast and low-cost construction methods. One of the key points of construction research. [0003] The steel structure of an electronic factory building in China is a multi-layer steel truss structure with a super large plane, with a length of 478 meters, a width of 258 meters, and a height of 42.5 meters at the highest point. The second floor of the c...
