Description

Technical Field

[0001] The utility model relates to the technical field of beam lifting and moving operations, in particular to a lifting tool for prefabricated T-beam side beams. Background Art

[0002] Lifting and moving T-beams is the most risky process in the beam yard, especially when lifting side beams. The side beam diaphragm is 3-5 tons heavier than the flange. Using a single wire rope to lift and move the beam can result in unsafe sideways tilting.

[0003] The current traditional process is to use reserved lifting holes to ensure that the distance from both sides of the beam to the center line of the beam is equal during the lifting operation, thereby making the beam balanced.

[0004] This process has five hidden dangers: 1. The reserved lifting holes are equipped with tooling, which is installed on the bridge wing plates. During installation, some transverse and longitudinal reinforcements need to be cut off, which affects the stress on the beam wing plates; 2. They need to be pulled out in time after pouring. After removing the formwork, the reserved holes are opened from bottom to top, which can easily cause the wing plate concrete to fall off; 3. After the beam is erected, the lifting holes need to be blocked, the formwork installed, the same grade concrete poured, and steel bars added, resulting in waste of materials and labor; 4. The stacking of hole formers on site affects the requirements of civilized construction on site. If the formwork for blocking the lifting holes is not installed in place, it can easily cause the wing plate ground to be uneven, water leakage problems, and an ugly appearance of the beam; 5. The lifting holes are blocked on the edge of the bridge deck, which requires personnel protection, especially when the formwork is installed, it is more inconvenient, and it is easy to cause safety hazards.
