Stiffening manner and temporary stiffener null of steel-frame beam at time of floor

摘要

PURPOSE: To reduce a construction cost by a method wherein deficiency in rigidity of a steel frame beam during construction of a floor is supplemented without unnecessarily increasing the section of the steel frame beam and using a lateral rigidity supplementing material. ;CONSTITUTION: Inner and outer materials being of lattice structure and formed in 6 square in cross section are assembled in a slide type. A temporary constructed rigidity supplementing material 1 provided at two ends with length fine adjustable joint parts of a gusset plate is caused to span a steel frame beam 12 and each of beam members on both sides of the steel frame beam and securely pressed against both sides of the steel frame beam 12 to supplement rigidity. After concrete is placed and cured, the temporary constructed rigidity supplementing materials 1 are contracted for removable.;COPYRIGHT: (C)1994,JPO
