Abstract

The invention discloses a method for installing a large-volume steel frame flue. The ground installation of the steel frame and the flue includes the following steps: S1: first prepare the steel frame foundation, and then lay wires on the steel frame foundation, Marking the installation position of the flue, and setting the wall plate, the bottom plate and the top plate at the installation position of the flue; S2 marking the installation position of the steel frame column at the wall plate; S3 Open at the installation position of the steel frame column, hang the steel frame column into the opening; S4 set the steel frame body on the steel frame foundation; also include the following steps: S5 install and flip Jack; S6 lifts the inverted roof to complete a lifting stroke of the inverted pull rod; S7 lifts the inverted roof after the lifting stroke of the inverted pull rod is completed, and repeats from step S5 to complete the entire large section The installation of the flue. The beneficial technical effect of the present invention is reflected in: safe construction, short construction period, less requirements on the site, and no need to use large-scale hoisting equipment.

Description

technical field [0001] The invention relates to the technical field of installation of environmental protection equipment, in particular to a method for installing a large-volume steel frame flue. Background technique [0002] With the continuous improvement of environmental protection standards, the requirements for flue gas emission are becoming more and more stringent. The original environmental protection equipment of steel mills and power plants cannot meet the latest emission standards stipulated by the state. Only by upgrading or adding new environmental protection equipment can the emission requirements be met. [0003] Since most of the sintering machines in our country did not plan the environmental protection equipment site at the beginning of their construction, or the planning was small, and the environmental protection equipment installed in the early stage could meet the basic conditions of the design requirements at that time, most of the construction sites we...
