METHOD TO REDUCE SHRINKING DEFORMATIONS AND DISPLACEMENTS CAUSED BY FORCES IN CAST-IN-PLACE REINFORCED CONCRETE FLOOR PANELS

摘要

FIELD: construction, particularly to erect buildings and building structures having cast-in-place floor panels and coverings.;SUBSTANCE: method involves imparting convex shape to floor panel during concreting thereof by means of special form usage, wherein the form has shell-like working surface with designed rise defined by two values, namely by designed rise constituent determined from concrete shrinking deformation compensation conditions and by rise constituent, which is intended to compensate force-caused displacements in floor panel.;EFFECT: increased reliability and strength of floor structures due to shrinking deformation and displacement compensation.;3 dwg
