Description

Technical field:

[0001] The utility model relates to the technical field of building construction, and specifically relates to an assembleable hanging beam used for hanging a variety of prefabricated special-shaped steel cage modules. Background technology:

[0002] Buildings in the nuclear power field have the characteristics of thick walls and a large number of steel bars. The amount of steel bar binding is large, and the binding at the construction site takes a long time and is greatly affected by external factors. Compared with the traditional in-situ binding of wall steel bars, modular construction technology is used to bind the steel bars into steel cage modules at the assembly site and then hoist them to the construction site, which can significantly improve the construction progress. The wall steel cage modules in the nuclear power field are affected by structural functions and have a variety of shapes such as straight, L, T, and cross. However, traditional hanging beams are fixed straight, I-shaped, and other shapes. When used for the hoisting of special-shaped steel cages, due to the fixed shape of the hanging beam and the limited selection of the lifting point position, the sling between the steel cage and the hanging beam will have a large inclination angle, resulting in excessive bending moment and torque on the steel cage during the hoisting process, resulting in deformation. The steel cage module has not yet formed a stable structure. When a hanging beam with the same shape as the steel cage is used, the sling between the steel cage and the hanging beam can remain in a nearly vertical state, reducing the force on the steel cage in the horizontal direction, thereby reducing the displacement and deformation of the steel cage.

[0003] However, the existing fixed-shape hanging beams are difficult to meet the lifting requirements of various shapes of steel cage modules. Therefore, the utility model provides an assembleable hanging beam for lifting a variety of prefabricated special-shaped steel cage modules, which can solve the problems of high cost and material waste caused by the need to customize the hanging beams one by one for prefabricated special-shaped steel cage modules in actual projects. Through different assembly forms of a set of hanging beams, the lifting requirements of various prefabricated special-shaped steel cage modules can be met. Summary of the invention:
