Hoisting tool special for prefabricated bridge deck slabs

Abstract

The invention relates to a hoisting tool special for prefabricated bridge deck slabs. The hoisting tool comprises a load-bearing comb-shaped steel plate, hoisting ropes, reinforcing steel bar hooks, reinforcing steel bar bolt and limit parts and is characterized in that two sides of the load-bearing comb-shaped steel plate are provided with hoisting holes, the hoisting ropes penetrate the hoistingholes, and a plurality of comb teeth are arranged at the lower end of the load-bearing comb-shaped steel plate; the reinforcing steel bar hooks are welded to the comb teeth at the lower end of the load-bearing comb-shaped steel plate; the reinforcing steel bar bolt is arranged in the reinforcing steel bar hooks, and the limit parts are arranged at two ends of the reinforcing steel bar bolt. The hoisting tool has the advantages that the hoisting of the prefabricated bridge deck slabs can be facilitated, damage to the prefabricated bridge deck slabs can be avoided, reinforcing steel bar hoisting rings embedded into the prefabricated bridge deck slabs can be avoided, the subsequent reinforcing steel bar hoisting ring cutting procedure is omitted, the potential channel corrosion hazard causedby the residual embedded reinforcing steel bar hoisting rings is eliminated, the construction procedures of the prefabricated bridge deck slabs are simplified, and the hoisting tool is safe and efficient in hoisting.

Description

technical field [0001] The application relates to a spreader, in particular to a special lifting spreader for a prefabricated bridge deck. Background technique [0002] Reinforced concrete composite bridges have the advantages of steel bridges and concrete bridges, and have been used more and more in the fields of architecture and bridge structures, and have achieved significant economic and social benefits. The application of prefabricated assembly technology to make bridge components industrialized, standardized and modularized is conducive to speeding up the construction progress, reducing labor intensity, improving project quality, and is conducive to environmental protection, reflecting the construction concept of energy saving and environmental protection. [0003] At present, during the installation and construction of the prefabricated bridge deck, the steel bar rings are pre-embedded in the bridge deck, which will damage the prefabricated bridge deck during the hois...

AI Technical Summary

Problems solved by technology

[0003] At present, during the installation and construction of the prefabricated bridge deck, the steel bar rings are pre-embedded in the bridge deck, which will damage the prefabricated bridge deck during the hoisting process, and after the bridge deck is installed in place, the steel bar rings need to be cut off for normal use. Increase the cutting process and prolong the construction time, and the steel bars remaining in the prefabricated bridge deck have hidden dangers of corrosion channels
