Problems solved by technology
[0002] During the construction process, steel corridors are often used to connect two buildings due to the needs of architectural shapes. The steel corridors are tens of meters long, and the radius of the steel beam arc is more than 100 meters, which brings great difficulties to the hoisting of the steel corridors. difficulty
[0003] For example, the No. 2 and No. 3 buildings of Tianjin Shenzhou Science and Technology Plaza project are connected by a steel corridor. The steel corridor is 32m long and is a side arc structure. The highest installation height of the steel beams in the corridor is 40.5m, and there are underground garages around Buildings 2 and 3, so large cranes cannot enter the site to lift the steel beams

The invention discloses a lifting lug device for side-arc steel beam lifting and an application method thereof. A side-arc steel beam is made from arc H-shaped steel, and comprises an upper flange plate, a lower flange plate and a belly plate arranged between the upper flange plate and the lower flange plate, and lifting points of the side-arc steel beam are located on the outer side of the side-arc steel beam; the lifting lug device comprises a transverse lifting beam plate and a lifting beam supporting plate, the transverse lifting beam plate is fixedly installed at the top of the upper flange plate, the end of the transverse lifting beam plate extends out of the edge of the upper flange plate, a lifting hole is formed in the portion, corresponding to the lifting points, of the extendingend of the transverse lifting beam plate, and the lifting beam supporting plate is installed between the lower flange plate and the extending end of the transverse lifting beam plate. According to the lifting lug device for side-arc steel beam lifting and the application method thereof, the aim that the side-arc steel beam is perpendicularly lifted can be achieved.
Description
technical field [0001] The invention relates to a side-arc steel beam, in particular to a lifting lug device for hoisting a side-arc steel beam and a method for using the same. Background technique [0002] During the construction process, steel corridors are often used to connect two buildings due to the needs of architectural shapes. The steel corridors are tens of meters long, and the radius of the steel beam arc is more than 100 meters, which brings great difficulties to the hoisting of the steel corridors. difficulty. [0003] For example, the No. 2 and No. 3 buildings of Tianjin Shenzhou Science and Technology Plaza project are connected by a steel corridor. The steel corridor is 32m long and is a side arc structure. The highest installation height of the steel beams in the corridor is 40.5m, and there are underground garages around Buildings 2 and 3, so large cranes cannot enter the site to lift the steel beams. Therefore be badly in need of proposing a kind of hois...
