ABSTRACT:
Apparatus is provided for production of concrete slabs wherein a reinforced elongated concrete slab is progressively formed on longitudinal supports following the installation of the supports by mounting carriages for movement along the length of the supports, providing the carriages with a leading platform portion to facilitate construction of a metal rod reinforcement core spanning the supports and a trailing slab forming platform. A reinforcing core is built up on the leading platform, a concrete slab is cast around a previously formed core on the trailing platform, the core built-up on the leading platform is suspended from the supports, and after the concrete has set sufficiently to provide a self-sustaining reinforced slab, the platforms are lowered, the carriages are advanced to position the trailing forming platform under the suspended reinforced core with the leading platform spanning the supports ahead of the core, the platforms are raised to the desired level for casting a continuation of the slab and for forming a continuation of the reinforcing core and the core forming and concreting steps are repeated. The apparatus is especially useful for forming the carriageway or road on bridges. The platforms may be suspended from below or above the tops of the supports and a cantilever C-shaped suspension may be provided for a slab portion, such as a walkway, extending laterally beyond an outer support.
