摘要
PURPOSE: To promote work efficiency by providing a recessed groove on the peripheral surface of an RC column of the lower part of a steel frame beam in a joint section crossing the RC column and steel frame beam, fitting an enclosed type band-plate surrounding a column main reinforcement to the recessed groove. ;CONSTITUTION: A recessed groove 3 equivalent to a fire resistance coating material surrounding the peripheral surface of a column A is formed downward of a lower flange of a steel frame beam B in the precast concrete column A connecting the steel frame beam B to a column capital section. An enclosed type band plate 4 is fitted into the recessed groove 3 so as to surround a column main reinforcement 1, and a fire resisting member 5 formed of a cement plate, etc., is filled thereinto through adhesives 6. Accordingly, it is not necessary to spray the fire resistance coating material, so that better display can be obtained because of no sprayed-on surface.;COPYRIGHT: (C)1994,JPO&Japio
