METHOD OF NON-FIREPROOFING CONSTRUCTION BY CONCRETE PLACING BETWEEN STEEL-FRAMED BEAM FLANGE AND FORM USED

摘要

PURPOSE: To prevent a troublesome fireproofing in the periphery of a beam made of steel in a building, in which a deck slab is laid on the beam having upper and lower flanges and being made of steel. ;CONSTITUTION: Four reinforcements 7 are laid around an I steel beam 1, the lower flange 6 is worked as the bottom plate of forms in combination, and both side plates 9, 9 of the forms are engaged and held among both side ends of the lower flange 6 and a form bottom plate 2a for a deck slab 2 in a tapered shape. Simple forms 3a, to which concrete placing holes 3b are bored and which are used for lower-end reinforced concrete beams 3, are shapedly provided among both side plates 9, 9 and an upper flange 5, and a lower-end reinforced concrete beam is shapedly provided and formed to a lower section in a tapered shape while wrapping the I steel beam 1 at the time of the concrete placing of the deck slab in an upper section.;COPYRIGHT: (C)1994,JPO
