Reinforcement cage for building material pipe pile production

Abstract

The utility model provides a reinforcement cage for building material pipe pile production, and relates to the field of reinforcement cages. The upper end and the lower end of the reinforcement cage body are each sleeved with an end fixing cover. Positioning plates are inserted into the upper end and the lower end of the reinforcement cage body and located at the opposite ends of the two end fixing covers correspondingly. Through the arrangement of the plug-in type limiting parts, when the two end fixing covers are fixed to the upper end and the lower end of an erecting steel bar, more time and labor are saved, even if the two end fixing covers are fixedly installed, the end fixing covers can be detached only by reversely rotating a worm, and therefore the using flexibility of the steel bar cage is improved; the problems that when end fixing covers are installed at the two ends of an existing steel reinforcement cage for tubular pile production, due to the fact that upset heads at the ends of erected steel bars are beaten into upset head grooves to achieve fixation, time and labor are wasted in the fixed installation mode, and the end fixing covers are inconvenient to detach once fixed installation is completed are solved.
