Background
With the rapid development of the building industry in China, the steel structure is increasingly applied to building construction due to the characteristics of environmental protection and energy conservation, and the steel structure becomes one of the main building structure types in China at present.
In steel structure construction, steel frame construction is one of the types that uses more, and steel column often adopts H type steel column in the steel frame construction. When the steel frame is installed and constructed, the H-shaped steel column is hoisted firstly, and then the steel connecting beam is installed. Before the steel connecting beam is installed, in order to ensure the stability of the H-shaped steel column, the H-shaped steel column is generally fixed by adopting a wind-collecting rope. When the steel connecting beam is installed, the wind rope drawing side can be detached. Because of the complex diversity of construction sites, in some cases, wind ropes cannot be arranged, so that a construction unit performs steel frame installation construction under the condition that the wind ropes are not arranged, and potential construction safety hazards are brought. Therefore, the research and development of the H-shaped steel column temporary supporting device which can adapt to various conditions, can be reused, has a simple structure and is easy to operate, and the use method is particularly important.

The mode of temporarily fixing the H-shaped steel column by adopting the cable rope requires that the steel column is provided with sufficient space around, and the space required by the cable rope is larger because the cable rope is generally led out from the top of the H-shaped steel column and keeps a certain angle with the horizontal plane. The mode of adopting a plurality of cranes requires more than two cranes to operate simultaneously on site, so that the required operation space is larger, and meanwhile, the construction cost is increased due to the increased number of the cranes.
