ABSTRACT:
A road transportable concrete railroad long-line tie molding system is described in which a rigid horizontal metal stressing frame is assembled from transportable sub-frame segments. The sub-frame segments are releasably connected in axially aligned end-to-end relation, and include parallel longitudinal reaction members. In a preferred form, the sub-frame segments are convertible from inoperative transport conditions to extended operative conditions. Footings are provided along the stressing frame length to engage the sub-frame segments to releasably mount the sub-frame segments in axial alignment and stabilize the reaction members against lateral deflection during compressive loading. A plurality of conventional gang tie molds having upwardly open elongated mold cavities are releasably received in end-to-end alignment along the framework. A reinforcing wire anchor is provided on the sub-frame at the dead end of the framework and a tensioner is located at the live end of the framework. The tensioner and anchors are adapted to receive and position an array of longitudinal reinforcing wires within the mold cavities. The wires are placed in tension against the reaction members, which react in compression. Both tension and compression forces are isolated from the tie molds. The tensioning forces applied between the tensioner and anchors are distributed about a centroid. The reaction members are positioned in concentricity with the centroid to avoid eccentric loading of the reaction members.
