Embodiment 1

[0022] A method for installing a steel column of a process steel platform in a benzene hydrogenation steel structure installation project, characterized in that it comprises the following steps:

[0023] a. Hoisting steel columns, the steel columns are shaped steel columns, the first section of steel column is hoisted in place and fixed with anchor bolts, the second section and above steel columns are first fixed with 1 / 2 ordinary bolts, and then clamped with web connecting plates , the lug plate is fixed with ordinary bolts, and the high-strength bolts are replaced after the adjustment of the steel column;

[0024] b. Calibrate the steel column. After the steel column is in place, use the crane, steel wedge and backing plate to adjust the elevation first, then adjust the torsion, and finally adjust the verticality. After the frame is formed, no overall correction will be made;

[0025] c. Measure and control the steel columns in the installation of the multi-layer steel frame...

Abstract

The invention discloses a method for mounting process steel platform steel columns in a project of mounting a benzene hydrogenation steel structure. The method is characterized by comprising the following steps of: a, hoisting steel columns; b, correcting the steel columns; c, measuring and controlling the steel columns during the mounting of a multilayer steel framework; d, mounting multiple layers of process steel platform steel beams; e, connecting the steel columns with framework webs and flanges, and f, mounting secondary beams and platform planks. The method for mounting the process steel platform steel columns in the project of mounting the benzene hydrogenation steel structure has the advantages of reasonable manufacturing step design, simpleness in operation, safe and reliable construction quality and low construction cost.

Description

technical field [0001] The invention relates to a method for installing a steel structure of a main body frame, in particular to a method for installing a steel column of a process steel platform in a benzene hydrogenation steel structure installation 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, in the electrical installation of these facilities, there are special requirements for lightning protection, fire protection...
