Abstract

An automatic or active shoring apparatus and process for controlling the deflection of the beams and girders typically in an elevated structure prior to and while concrete is placed and screeded on the beams and girders comprises a beam adjusting device and a beam monitor. The beam adjusting device is operable to adjust a curvature of the beam in response to the beam monitoring device, which measures and monitors the curvature of the beam throughout the placing and screeding processes. The beam adjusting device may comprise a heating device with or without a cooling device such as a fan, a cooling device, an adjustably weighted container, or a horizontally mounted fluid cylinder or jack. The curvature of each beam is automatically adjusted and maintained at a substantially level orientation prior to and while concrete is placed, screeded and cured at each beam. The present invention thus avoids the necessity of pre-placing concrete at the beams and further results in a slab where the concrete may be placed more efficiently and more accurately over conventional processes. Aspects of the present invention may be equally applicable on precambered beams as well as on straight or level beams.
