Among them, prefabricated steel structures have been widely used due to their advantages of lightweight, standardization, modularization, simplicity, etc. Due to the standardized and modular construction requirements of prefabricated steel structures, there is no segmented bracket of the steel beam on the steel column, but the natural length of the steel beam is used instead. When installing the steel beam on the steel column without the bracket, the construction workers have no working platform. In the past, the construction workers had to stand on the ladder to operate, which is not only inconvenient but also has a high safety risk. Utility Model Content

[0012] The beneficial effects of the utility model are embodied in:

[0013] 1) The utility model provides a steel beam installation operation platform structure without a corbel steel column. By installing the operation platform on the steel column without a corbel steel column, the problem that the construction workers have no foothold when installing the steel beam without a corbel steel column and need to stand on a ladder set up separately is successfully solved. It is more convenient to construct on the operation platform. At the same time, the workers can hang the safety rope on the ear plate of the steel column during construction, and hold the connecting plate just above, which provides a standing operation space for the installation of the side steel beam. In addition, the fixing form of the steel wire rope and the steel column is more stable and firm than the ladder, which reduces the safety risk of the workers during construction.

[0014] 2) The utility model provides a steel beam installation operating platform structure without corbel steel columns. The operating platform can be installed on the steel column before the steel column is hoisted, and can be flipped and folded, which does not take up space and does not affect the hoisting of the steel column. It is convenient to install and dismantle, and can be recycled after dismantling, and has strong economy and turnover.
