Method for installing main body frame steel structure of benzene hydrogenation project

Abstract

The invention relates to a method for installing a main body frame steel structure of a benzene hydrogenation project. The method is characterized by comprising the following steps of: a, dividing hoisting areas of frame steel structures, dividing hoisting areas of multi-layer and high-rise frame steel structures according to the operating range of a tower crane to ensure that steel members are hoisted sequentially and simultaneously in parallel, hoisting from the middle or a certain symmetrical panel of a plane, hoisting by taking a column grid of a panel as a hoisting unit according to the sequence of steel columns, steel beams and supports, and expanding towards the periphery; after a stable structure is formed from bottom to top in the vertical direction, installing minor structures layer by layer, namely arranging the minor structures on the steel members of each panel in each floor; b, measuring, correcting and performing initial screwing by using a high-strength bolt after the frame steel structures of a district are hoisted, measuring, correcting, performing the initial screwing by using the high-strength bolt and welding after the frame steel structures of several districts are installed, and hoisting the next section of the steel column; and c, hoisting, releasing and paving combined floor compression steel plates.

Description

technical field [0001] The invention relates to a method for installing a frame steel structure, in particular to a method for installing a frame steel structure of a main body of a benzene hydrogenation project. Background technique [0002] The process of benzene hydrogenation unit is quite special, its system is complicated, there are many equipments, the pressure and temperature of the system itself are high, and the pump equipment is not allowed to run idle. The benzene hydrogenation project is mainly divided into the central control room and substation, refining device, water supply and drainage project, air compressor station, storage and transportation facilities (tank farm and pump room), power supply for the whole plant and lighting for the whole plant, torches and ancillary projects facilities, there are special requirements for lightning protection, fire protection and explosion protection in the installation of these facilities, and the installation of the steel...

AI Technical Summary

Problems solved by technology

At present, the installation of the main frame steel structure of the benzene hydrogenation projects that have been built or are under construction in China is still in the non-standard stage, and there are many unscientific and unreasonable places. The production process is complicated and the production cost is high.

[0003] Therefore, there are above-mentioned inconveniences and problems in the known benzene hydrogenation project main frame steel structure installation method
