Steel wire knotting device for building construction and steel wire knotting method for construction

Abstract

The invention belongs to the technical field of steel wire knotting and especially relates to a steel wire knotting device for building construction. The device comprises a binding driving bar, a conveying guiderail, a shell and a steel wire conveying mechanism. During binding of reinforcing steel bars, the conveying guiderail is at first hooked between the two reinforcing steel bars to be bound,so a turntable installed on the binding driving bar can be pressed on the two reinforcing steel bars; then, a binding mechanism is moved upwards for a short distance, a driving motor is switched on bya switch button and starts work, a steel wire clamped in advance inside the shell is conveyed out by the steel wire conveying mechanism, and a speed reduction stepping motor starts work when a secondsteel wire thickening end on the steel wire gets contact with a sensor on the shell; and the binding driving bar is driven by the speed reduction stepping motor to rotate and wind the steel wire. Incomparison with traditional manual binding, the device disclosed by the invention has the beneficial effects that binding efficiency is high and workers' labor strength is low; and in comparison withexisting binding machines of reinforcing steel bars, the device can be operated conveniently and can be operated with one hand.

Description

technical field [0001] The invention belongs to the technical field of steel wire knotting, and in particular relates to a steel wire knotting device for building construction and a steel wire knotting method for building construction. Background technique [0002] In modern society, infrastructure is essential to the country. During construction projects, steel bars are usually bound into a frame and then poured with cement to form reinforced concrete. Its toughness and firmness are good, so it can be developed on a large scale. If the binding between the steel bars in the frame structure is manually bound, the binding efficiency is low. After working for a long time, the forearm will be severely sore, and the labor intensity of the worker is relatively high. [0003] Now there are various automatic steel bar binding machines on the market, which greatly improves the efficiency of binding; greatly shortens the binding time and reduces labor costs; but the current steel bar ...

Problems solved by technology

If the binding between the steel bars in the frame structure is manually bound, the binding efficiency is low. After working for a long time, the forearm will be severely sore, and the labor intensity of the workers will be high.

[0003] Now there are various automatic steel bar binding machines on the market, which greatly improves the efficiency of binding; greatly shortens the binding time and reduces labor costs; but the current steel bar binding machines often need two hands to operate at the same time, and the steel wire When bypassing the lower side of the steel bar, it needs to be completed manually. Only the tightening of the steel wire is completed by a binding machine, and the actual operation is more troublesome, so most of them still use manual binding at present. The invention designs a reasonable structure, convenient operation, A rebar binding machine that is able to operate with one hand and route the wire from the underside of the rebar without human involvement is essential when tying
