Cantilever crane beam installation process

Abstract

The invention discloses a cantilever type crane beam installing technology. The cantilever type crane beam installing technology comprises the steps that bracket column and crane beam connecting hole adjustment is conducted, chambering installation is adopted, and strengthening plates are additionally arranged on the face not influencing tracks and are drilled; elevation adjustment is conducted, after bracket column installation is finished, whole-course retest is conducted on the bracket column elevation firstly, the manufactured section height of each crane beam is checked, and after errors are found, and abrasive cushion plates are additionally arranged on the surfaces of bracket columns for adjustment; upper beam and lower beam track horizontal distance adjustment is conducted, if adjustment is conducted towards the inner sides of the bracket columns, abrasive cushion plates are additionally arranged at the upper beam and bracket column connecting positions, if adjustment is conducted towards the outer sides of the bracket columns, a notch is formed in an upper beam through repairing, meeting of the requirement for the adjusted distance is the standard, then, flange slabs the same in size are additionally made for equal-strength welding, and the adjusted distance for the outward movement is achieved for the upper beam. By the adoption of the cantilever type crane beam installing technology, construction precision control, construction scheme optimization and integral structure safety control can be more efficiently achieved

Description

technical field

[0001] The invention relates to the technical field of installation and construction of a steel structure factory building, and is mainly used for the installation of a cantilevered crane beam in a steel structure factory building. Background technique

[0002] With the rapid development of my country's construction steel structure industry, the amount of portal steel structure factory buildings has increased significantly. This structural form can play an active role in improving the efficiency and industrialization of factory building construction, and has a broad market demand space. Steel structure workshops generally have the characteristics of light weight, energy saving, good durability, and good economy. This is in line with my country's energy-saving and industrialization-oriented industry policies. Therefore, my country has successively issued a series of policies to promote the construction and development of steel structure workshops. industrial su...
