Abstract

The invention discloses a high-altitude large-span steel beam mounting method, which is characterized in that through step-type cutting, a supporting point can be established for a large-span steel beam in the air by utilizing the advantages of step-type cutting, so that a stable welding environment can be provided while the span and the weight of a single component are reduced; and the side section which is hoisted and connected in advance is used as a working surface of the next middle section mounting procedure, so that the welding quality is guaranteed, and meanwhile, the safety coefficient in the construction process can be improved. The problems that a traditional high-altitude large-span steel beam installation method has high requirements for hoisting machinery and welding quality is difficult to guarantee in the installation process are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for installing a high-altitude large-span steel beam. Background technique [0002] For the high-altitude installation of large-span steel beams, especially the span of a single steel beam reaches 30m and the weight is about 11 tons, for long-span high-altitude hoisting and welded steel beams, the traditional treatment method is to set up a tire frame under the steel beam. The whole steel beam is hoisted to the design elevation by a tower crane, and the workers connect the steel beam to the steel structural columns at opposite ends of the whole steel beam by vertical groove welding or bolt connection. The traditional installation method has the following problems: first, the single hoisting span and weight are large, which puts forward higher requirements for hoisting machinery and safety; It is easy to shake, and the welding quality is difficult to guaran...
