[0002] A T-beam is a structural beam with a T-shaped cross-section. It is commonly used in construction, bridges, mechanical equipment, transportation vehicles and other fields to carry and transfer loads. The cross-sectional shape of the T-beam is a "T" shape, in which the horizontal part at the bottom of the beam is the cross beam, and the vertical part at the top of the beam forms a beam column. This cross-sectional shape gives the T-beam higher strength and rigidity, enabling it to effectively bear loads and resist deformation.

[0003] Since the force-bearing area of ​​the T-beam's fulcrum is small during transportation, and the height difference between the mid-span and the two fulcrums is large, the T-beam becomes top-heavy and bottom-light during transportation, which makes it easy for it to become unbalanced during transportation. Therefore, it is difficult to ensure the stability of the T-beam during transportation.

[0004] For this reason, a T-beam fixing device for railway construction is proposed. Utility Model Content
