Abstract

A locating-plate-based quick installation method for a steel structure roof beam is characterized by comprising the following steps: a, prefabricating a steel structure roof beam (1), b, prefabricating a locating plate (5), c, prefabricating a movable connecting plate (2), and d, hoisting the steel structure roof beam. The locating-plate-based quick installation method for a steel structure roof beam, provided by the invention, has the following advantages: the locating plate and the movable connecting plate are simple in structure, convenient to fabricate, and safe and reliable to use; the accuracy of perforation is improved in roof beam fabrication; quick stress is applied to the roof beam in a backing fixing way for the locating plate, and the objective of achieving advanced unhooking of a crane is achieved with reduced construction cost of an installation project.

Description

technical field [0001] The invention relates to a method for installing a steel structure beam of an industrial factory building, in particular to a method for quickly installing a steel structure roof beam based on a positioning plate. Background technique [0002] During the installation and construction of the steel structure of the main factory building in the No. 3 Cold Rolling Zone 7 of Caofeidian Shougang Phase I, the installation of roof beams is very large. The steel columns of the main factory building are double-tube H-shaped steel columns, and the material is Q345B. The length of the beam is 33 meters, the weight of a single piece is 18 tons, and the connection method of the roof beam is bolted welding. During the on-site installation and construction, it is necessary to use large-scale hoisting machinery to hang the roof beams. The hooks can only be loosened after the completion of construction steps such as assembling the roof beam web connection plate, fasteni...
