Scaffolding structure using compositive section beam introducing prestress by maximizing rigidity and eccentricity by combination of various sections

摘要

PURPOSE: A scaffolding structure using compositive section beam introducing prestress by maximizing rigidity and eccentricity by combination of various sections is provided to reduce the number of mold beams by widening the interval of the steel material cross sections. CONSTITUTION: A scaffolding structure using compositive section beam introducing prestress comprises a cross beam, a construction vent(13), a free end(120), a fixed end connection support(130), a precast deck(21), a composition part side(20), a free cast connection part(30) and a mold connection part(50). The constructive bent is installed on the ground. The free end and fixed end connection support are installed on the constructive bent. The precast deck is installed on the free end and fixed end connection support.
