A steel bar tightening device for construction

Abstract

The invention discloses a steel bar tightening device used in construction. Its structure includes a battery, a handle, a start button, an electric drill drive body, a shaft coupling, a transmission shaft, and a wire binding device. The wire binding device consists of a shaft connection mechanism, Composed of a rotating sleeve and an iron wire twist knot tightening mechanism, the present invention has the effect: through the iron wire binding device, the tentacles at both ends of the untightened iron wire at the overlap of the steel bars are automatically moved by the front end of the upper push block and the lower push block. Attracted by permanent magnets, using the rotating force of the transmission shaft, the two ends of the iron wire are entangled with each other, forming a tight twist knot and fixed at the overlap of the two steel bars, so as to solve the problem of the existing automatic steel bar tightening equipment compared with artificial steel bars. The binding operation wastes iron wire, increases the cost of iron wire, and the adjustment of the tightness gear of the binding is limited, which cannot meet the needs of binding and tightening steel bars with different diameters.

[0002] In the process of building construction, it is necessary to weave and tie the lapped steel structure on the roof to facilitate better and safe concrete pouring construction. During the process of steel bar lapping, the two steel bars overlap each other and need to be connected by wire binding. , the steel bar connection method of binding with wires, most construction sites bind the steel bars manually, with the development of industrial manufacturing technology, a fully automatic steel bar tightening equipment, also known as a fully automatic steel bar binding machine, is a hand-held battery-type steel bar The fast binding tool can automatically complete all the steps of steel bar binding to replace manual binding of steel bars, but the existing automatic steel bar binding machine wastes iron wire compared with manual operation, and the cost of iron wire increases by 20-30%. The adjustment of the tightness of the bundling is limited, which cannot meet the needs of bundling and tightening of steel bars with different diameters. Therefore, it is necessary to develop a new type of steel bar tightening equipment for construction, in order to solve the problem of the existing automatic steel bar tightening equipment compared with artificial steel bars. The binding operation wastes iron wire, increases the cost of iron wire, and the adjustment of the tightness of the binding is limited, which cannot meet the needs of binding and tightening steel bars of different diameters
