EXPANDED CHORD TYPE FORM SUPPORTING METHOD USING STEEL BEAM SEAT TO WHICH PRESTRESS IS INTRODUCED

Document Type and Number:

Japanese Patent JPH01268969

Kind Code:

A

Abstract:

PURPOSE: To reduce deflection caused by loading by pulling down steel beam seats curved upward by introduction of prestress by a vertical expanded chord, deforming elasticity so as to restore the deflection and executing a required concrete work.

CONSTITUTION: Steel beam seats 1 curved upward by introduction of prestress caused by clamping a horizontal expanded chord 2 are installed in a plurality of required places at an equal interval in parallel. The middle part of these steel beam seats is pulled down by a vertical expanded chord 4 to deform elasticity so as to restore the deflection, and flat state is maintained. After that, slab forms 5 are bridged to the steel beam seats 1 to arrange arrangement, piping, etc.; after placing concrete until the tensile force of the vertical expanded chord 4 is dispersed, the vertical expanded chord 4 is removed. Accordingly, the execution can be easily made.
