Longitudinal bar locker at the end of steel frame machine

Abstract

The invention discloses a steel reinforcement framework machine end portion longitudinal bar locker. The steel reinforcement framework machine end portion longitudinal bar locker comprises a penetrating reinforcement block, the penetrating reinforcement block is provided with a circular penetrating reinforcement hole and a rectangle locking hole, the penetrating reinforcement hole is communicated with the rectangle locking hole, and the diameter of the penetrating reinforcement hole is bigger than the width of the locking hole; a lead screw penetrates through the locking hole, and the lead screw is provided with an elastic sleeve head and a locking block which are arranged on two sides of the penetrating reinforcement block; the elastic sleeve head is provided with a hand shank and a locking pressing plate, and the locking pressing plate is of an eccentric circular and used for compressing a longitudinal bar; the locking block is provided with a threaded hole which is matched with the lead screw in a threaded mode, the section of the locking block is of a T shape in the direction of the lead screw, and the locking block is matched with the rectangle locking hole to form a sliding pair; a longitudinal bar end portion axial direction position block is arranged on the penetrating reinforcement block corresponding to the penetrating reinforcement hole, and the position block is fixedly connected with the penetrating reinforcement block. By means of the steel reinforcement framework machine end portion longitudinal bar locker, fixing and locking longitudinal bar end portion is more convenient and reliable, and the arrangement of the longitudinal bar end portion is neat.

Description

technical field [0001] The invention belongs to the technical field of steel bar frame forming construction in the construction industry, and in particular relates to a longitudinal bar locker at the end of a steel bar frame machine. Background technique [0002] The steel skeleton is formed by welding multiple round or square longitudinal bars and spiral stirrups wound on the longitudinal bars by a special seam welding machine. When the steel frame is formed, a driving system is required to drive the entire longitudinal bar and the formed frame to rotate relative to the traction system to realize the winding of the stirrup on the longitudinal bar. This forming method improves the mechanization level of the steel frame forming to a certain extent, but There is still a gap with the energy-saving and environmentally-friendly production technology advocated by the country, and it is difficult to form the steel skeleton with polygonal cross-sections of different specifications b...

Problems solved by technology

However, this kind of fixing device is tightened by the end of the fastening bolt. For rebars of different diameters, the tightening position is prone to eccentricity; the ends of the longitudinal ribs must extend into the rib-piercing pipe, which is time-consuming and laborious; the tightening bolts need to be tightened with a wrench , inconvenient to operate
