Vibrating slipform paver comprising a device for inserting reinforcing bars in a freshly-laid road surface

摘要

This road-building machine of the Gleitschalungstyps has a device (20) for inserting reinforcing bars in the road surface at joints locations behind the paver (1). This device (20) comprises a plate (21) with slots (26), the retaining baskets (27, 28) for supporting the bars. The plate (21) is free of the finisher (1) rearwardly projecting beams (20a) suspended such that it floats freely above the road surface. In this plate main beams (50) are fixed, on each of which a vertical hydraulic cylinder (54) is suspended to vertikalverschieblichen supporting a vibrator beam arrangement (60). be located in this arrangement (60) on the slots (26) aligned in pairs arranged forks (63) with which the vibration is transmitted to the rods. A horizontal hydraulic cylinder (70) is on the one hand on the finisher (1) and on the other hand to the plate (21) is articulated. Thus rods can be hineinvibriert in the road surface without changing the structure of the concrete and without leaving traces visible from afar.
