Apparatus for producing reinforcing cages for rectangular pipes made of concrete

Abstract

A suitable automatically operating apparatus is proposed for producing reinforcing cages for rectangular pipes made of concrete. Longitudinal-wire sections, which are parallel to the pipe axis, are held together in a framework. The latter essentially comprises a perforated frame, which cannot be moved in the longitudinal direction, and a receiving frame, which can be displaced relative to the perforated frame. Rectilinear transverse-wire sections, angles or bent brackets are welded onto the longitudinal-wire configuration, to be precise onto the respective side surfaces of the longitudinal-bar configuration in a freely selectable manner. Fitting apparatuses which can be displaced perpendicularly with respect to the longitudinal-wire sections are used for this purpose. In addition to the wire thickness, it is also possible to select the spacings between the transverse-wire sections provided in each case. In the example, the framework can be rotated about a vertical axis on a carousel, in each case two mutually opposite fitting apparatuses interacting with two welding apparatuses arranged transversely thereto. The necessary transverse-wire sections are finished off in each case during the welding operation. The completed reinforcing cages are removed, and inserted one inside the other, by crane.
