A butt joint for steel bars

Abstract

The invention provides an abutting apparatus for reinforcing steel bars. On the basis of guaranteeing the abutting quality of the reinforcing steel bars and not increasing labor force, the construction speed of a sleeve joint of the reinforcing steel bars can be improved. The abutting apparatus for the reinforcing steel bars comprises a sleeve clamping fixture and a sleeve rotating clamp, wherein the sleeve clamping fixture comprises a clamping tube, a clamping handle and a gear; the sleeve rotating clamp comprises a rotating handle and a retainer ring; a ratchet matched with the gear and a first elastic component are arranged at a hinged part of the retainer ring; the first elastic part drives the ratchet to have a tendency of rotating towards one direction by taking a hinge point as a pivot. According to the abutting apparatus for the reinforcing steel bars, disclosed by the invention, the sleeve clamping fixture is used for fastening a sleeve; the sleeve rotating clamp is used for enabling the sleeve clamping fixture and the sleeve to jointly rotate so as to realize the abutting of two thread reinforcing steel bars; the sleeve clamping fixture and the retainer ring of the sleeve rotating clamp are of two split structures, so that the opening or closing can be conveniently realized; the abutting apparatus is particularly suitable for abutting the thread reinforcing steel bars of a filling pile in a deep pile hole, and is beneficial for safe production and improvement on the working efficiency of abutting of the reinforcing steel bars.

Description

technical field [0001] The invention relates to a steel bar butt joint appliance. Background technique [0002] In civil engineering, the processing, production and installation of steel bars are important construction contents. In order to facilitate the transportation and assembly of steel bars, the steel bars used in construction often need to be docked and lengthened for installation on site. There are many ways to lengthen the steel bar butt joint. The steel bar sleeve butt joint process is a relatively common construction process in the steel bar butt joint. Butt joint of threaded steel bar 1, before the butt joint of steel bars, such as figure 1 As shown, after the butt joint of steel bars is as figure 2 shown. The advantage of the steel bar sleeve butt joint is that it is convenient for construction, no need for electric welding machine welding, and the steel bar butt joint lengthening work can be completed at the construction site, and the steel bar sleeve proce...

AI Technical Summary

Problems solved by technology

Multi-person operation will increase labor costs, and the piling work area is very narrow and it is very inconvenient for multiple people to operate; although increasing the gap between the steel bar and the sleeve can reduce the difficulty of butt jointing of the steel bar, it will affect the quality of the butt joint of the steel bar
