Description

Technical Field

[0001] The utility model relates to the technical field of construction industry transportation, in particular to an improved prefabricated beam transportation and fixing tool. Background Art

[0002] Prefabricated beams are often used in the construction of prefabricated buildings, bridge municipal prefabricated components, and wharf prefabricated components. Among prefabricated beams, T-beams and rectangular beams are two common forms. T-beams are formed by digging out the concrete in the tensile area of ​​the rectangular beam that does not contribute to the bending strength. In addition to having exactly the same bending strength as the original rectangular beam, it can save concrete, reduce the deadweight of the component, and improve the spanning capacity. The special shape design makes the T-beam have the cross-sectional characteristics of a large upper cross-section and a small lower cross-section. In terms of weight distribution, it has the characteristics of being heavy on top and light on the bottom, and the center of gravity will move up to a certain extent. The upper and lower cross-sections of the rectangular beam are consistent. Although the shape does not have the uneven distribution of the upper and lower parts of the T-beam, the center of gravity distribution is also higher for some rectangular beams with a large height-to-width ratio.

[0003] For these two types of beams with a high center of gravity distribution, if there are no reliable fixing means and measures to fix the beams during the transfer transportation using flatbed trucks, the beams are prone to slippage or even instability and rollover due to bumps and uneven road conditions during transportation, with disastrous consequences. Under normal conditions, prefabricated beams can be fixed during transportation by tools such as ropes, but using ropes to fix them often requires a large amount of ropes and a large amount of manpower to tie and untie the ropes. In long-distance transportation, the ropes will not move for a long time after they are fixed, and the ropes will accelerate wear in the stressed state, which will pose a greater safety hazard over time. In short-distance transfers, due to the high frequency of transportation and loading and unloading, rope fixing is relatively time-consuming and labor-intensive, affecting the efficiency of transfer transportation; the ropes wear a lot and the maintenance cost is high; the wear of the ropes affects the fixing effect, and once the ropes break, it will cause safety hazards. For this reason, we propose an improved prefabricated beam transportation and fixing tool to solve the above problems. Utility Model Content
