Laminated slab exposed steel bar fixing method and special fixer thereof

Abstract

The invention relates to a laminated slab exposed steel bar fixing method. The laminated slab exposed steel bar fixing method comprises the following steps that firstly, the bending direction of exposed reinforcing steel bars and the length of the exposed reinforcing steel bars are adjusted, and upper and lower points of back-bending parts of the reinforcing steel bars are fixed by adopting vertical clamping strips; and then a bearing beam is cushioned below the roots of the steel bars, a steel plate is pressed on the roots of the steel bars, and the steel plate is powerfully attracted to the batten through strong magnetism. The invention further provides a special fixator for the laminated slab exposed steel bar fixing method. The special fixator comprises bearing beam steel plates arranged on the upper portions and the lower portions of the steel bars correspondingly; steel plate fixers are arranged at the two ends of the bearing beam, a sliding beam is parallel to the bearing beam, and the two ends of the sliding beam are fixedly connected with the two ends of the bearing beam through connecting bases; and a sliding block is arranged on the sliding beam, a pin is arranged on the side face of the sliding block, a U-shaped steel strip is arranged at the top of the sliding block, and two vertical bars of the U-shaped steel strip extend upwards and are clamped to the two sides of the bent parts of the exposed steel bars. The bent parts of the exposed steel bars are fixed through the U-shaped steel strip, the bent part is prevented from inclining in a bending direction, the steer bar exposing position can be conveniently fixed, and meanwhile, the production efficiency and the laminated slab quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of fabrication of fabricated laminated panels, in particular to a method for fixing exposed steel bars of laminated panels and a special fixer thereof. Background technique [0002] In the manufacture of prefabricated laminated slabs, in order to realize assembly and installation, four-sided ribs are provided, and the ribs are the parts outside the mold when the laminated slab reinforcement is arranged. The exposed steel bars of the laminated slab generally require a neat and equal-length standard layout. In order to meet the requirements of construction and on-site installation, one side of the ribs is often made into a curved shape, and when bent, the ribs are generally bent upwards to form a hook shape. [0003] Due to the lack of a fixed structure for the bar in the prior art, after the binding of the steel bar is completed, the upper part of the bent part is heavier than the lower part, and it falls un...

AI Technical Summary

Problems solved by technology

This method plays a certain role in fixing, but the binding point is the cross point of the steel bar, in fact, it cannot completely avoid the rotation of the exposed steel bar itself, so the bending part will still appear skewed

The fixing effect of the binding wire is completely dependent on the manual control of the position (orientation) of the bending part, and it is difficult to achieve complete consistency

If the rebar does not meet the requirements, it will be necessary to dismantle and fix the rebar a second time in the later stage, and the way of tying and fixing will consume a lot of tying wire, the tying process is time-consuming and laborious, and the effect cannot be guaranteed
