High-altitude safety assembly tire frame device for pipe truss and construction method thereof

technical field

The invention relates to the technical field of building construction, in particular to a high-altitude safety assembling tire frame device of a pipe truss and a construction method thereof.

Background technique

With the rapid development of my country's economy and technology, long-span steel structure pipe truss systems are widely used in construction projects, but the installation of large-span and heavy-weight steel structure pipe truss systems in large venues in the middle of the building is due to the construction site. The site is limited, and hoisting machinery cannot be used or the hoisting machinery cannot meet the hoisting requirements. It is necessary to erect a high-altitude assembly to support the tire frame, which is assembled in multiple truss units, and the construction is carried out with multiple slips.
