B, correction steel column, after steel column in place, use crane, steel are carved and are first adjusted absolute altitude with backing plate, then adjust torsion, finally adjust verticality, no longer do Integral correction after forming framework;
Steel column in c, observing and controlling composite steel frame installation, the observing and controlling of composite steel frame installation precision is based on observing and controlling steel column, observing and controlling steel column dropping place fixed vertical degree and capital axis, after considering steel girder erection, post beam splice Site Welding amount of contraction, the outward-dipping scope of steel column is (platform elevation location) 1 ~ 2mm;
D, installation multilayer technology steel platform girder steel, described technique steel platform girder steel is shaped steel;
E, connection steel column and Vierendeel girder web and the edge of a wing, steel column is connected with Vierendeel girder web high-strength bolt, and steel column and the edge of a wing are for being welded and fixed, and construction order is just twist high-strength bolt, then welds, last stubborn high-strength bolt eventually;
F, installation secondary beam and platform bed board, the platform surface of technique steel platform is waffle slab, pays civil engineering concrete platform after installation, welding secondary beam and platform bed board.
Process steel platform steel columns in project of mounting benzene hydrogenation steel structure mounting method of the present invention can also be further achieved by the following technical measures.
Aforesaid method, wherein said steps d installs multilayer technology steel platform girder steel, and the first therefrom span of same colonnade Vierendeel girder of multilayer technology steel platform girder steel starts to install, symmetry is expanded to two ends, when installing girder steel, verticality of steel column generally can not change, and uses transit tracking observation; If verticality of steel column is overproof, girder steel size should be checked and carry out necessary process.
Aforesaid method, wherein said steps d installs multilayer technology steel platform girder steel, after the same layer platform framework beam hoisted in position of multilayer technology steel platform girder steel, repetition measurement verticality, girder steel absolute altitude conform to quality requirements, connect with high-strength bolt, fix steel column and steel column, steel column and platform framework web.
After adopting technique scheme, process steel platform steel columns in project of mounting benzene hydrogenation steel structure mounting method of the present invention has the following advantages:
1, making step is reasonable in design, simple to operate;
2, workmanship is safe and reliable;
3, engineering cost is reduced.
Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
