Method for installing structural steel beam in steel structure work

Abstract

The invention discloses a method for installing a structural steel beam in steel structure work. The method includes the steps of manufacturing rotating hinges, installing the rotating hinges and hoisting the structural steel beam in position. Firstly, a steel beam connecting plate between the structural steel beam and a bracket is fixed on the structural steel beam through the two rotating hinges, when the structural steel beam is installed at the high altitude, secondary hoisting and carrying of the connecting plate are not needed, the using time number of a tower crane is decreased, the work efficiency is improved, and the method is safe and reliable. According to the technical scheme, when high altitude operation for connecting the structural steel beam with another structural steel beam and connecting the structural steel beam with the bracket is carried out, high altitude movement or steel beam connecting plate movement is not needed, the high altitude construction potential safety hazards are reduced, the labor production rate is improved, the production cost is reduced, the method is applicable, reliable and convenient to use, and a field operation worker can easily accept the method.

Description

technical field [0001] The invention relates to a method for installing a shaped steel beam, in particular to a method for installing a shaped steel beam in steel structure engineering. Background technique [0002] In recent years, my country's construction engineering technology has developed in the direction of large-span and super high-rise steel structures. The total span of the steel structure project of Zhuzhou Grand Theater in Hunan Province is 220m, and the high-end hotel and office building project of Building B3 of Changsha Poly International Plaza is 235m high. Steel frame---Reinforced concrete core tube structure, adopts new steel structure materials such as alloy steel and high-grade steel, which not only meets the functional requirements, but also saves energy and protects the environment. The construction speed is fast and the construction period is short. It is a new direction for the development of construction projects. [0003] There are a large number of ...

AI Technical Summary

Problems solved by technology

[0003] There are a large number of shaped steel beams to be installed in the steel structure project, all of which are high-altitude operations. When the shaped steel beams are connected to the shaped steel beams, and the shaped steel beams are connected to the corbels, when working at heights, it is necessary to move or move the shaped steel beam connecting plate at high altitude Due to the heavy weight of the steel components, it is very difficult to manually move the steel components during high-altitude operations, and the safety hazards are also great. For example, when the construction workers move the steel components, the components and personnel fall from high altitudes often occur, causing major safety accidents, reducing labor productivity and increasing cost of production
