Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary hoisting, in particular to an L-shaped hoisting frame. Background Art

[0002] With the rapid advancement of building industrialization, prefabricated components have become a key factor in improving building efficiency, quality and safety. Prefabricated concrete components (PC components) are widely used around the world due to their standardized production and rapid on-site assembly, especially in high-rise buildings, bridges, tunnels and residential industrialization projects. This production method not only significantly shortens the construction period, but also reduces on-site wet operations and improves environmental performance.

[0003] However, with the popularization of prefabricated components, the problems in the lifting process have become increasingly prominent. Traditional lifting methods usually rely on a hook structure set on the top of the prefabricated component, which is fixed by a metal grid or steel bar embedded in the concrete. Although this design is convenient for direct lifting from the top, it has several shortcomings in actual operation:

[0004] 1) Grid stress problem: When hoisting large or heavy prefabricated parts, the hoisting points are concentrated at the top, causing the grid to bear great shear force and tension, which can easily lead to insufficient bonding between the grid and concrete, causing the grid to fall out or partial damage to the concrete, affecting the integrity and safety of the prefabricated parts;

[0005] 2) Lifting stability limitation: When lifting only by the top lifting point, it is difficult to provide effective support for the prefabricated parts in the lateral direction, especially when there is wind force or slight deviation during the lifting process, which may cause the prefabricated parts to shake, increase the difficulty of lifting, and even endanger the safety of the operators;

[0006] 3) Limited installation flexibility: For construction sites with complex structures or limited space, the design of a single top hanging point limits the flexible adjustment and precise positioning of prefabricated parts, increasing the difficulty and cost of on-site construction.

[0007] Therefore, the market is in urgent need of a more advanced and reliable solution for the lifting of precast concrete components to overcome the limitations of existing technologies, ensure the safety and efficiency of the lifting process, and improve the flexibility and convenience of construction.
