Title: Synthetic beam
Inventor: WATANABE KO
IPC: E04B1/30
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a composite beam formed of steel and concrete capable of effectively introducing a prestress thereinto by preventing the steel from restricting the concrete until a specified time is elapsed immediately after the concrete is deposited to minimize the effects of deformation and constraint of concrete by steel materials on the deformation of the concrete caused by the introduction of a prestress into the concrete.
