FIRE PROTECTION APPARATUS BETWEEN FLOORS IN STEEL STRUCTURE

摘要

PURPOSE: A fire protection apparatus between floors in a steel structure is provided to fix a glass wool by using a channel, to install a steel plate and a foaming fireproof board in one body on a floor slab, and to seal a seam space using a foaming fireproof sealant, thereby making it unnecessary to doubly install steel plates on the floor slab and outer wall and making it possible to reduce air since it does not require any period for concrete curing. CONSTITUTION: The fire protection apparatus between floors in the steel structure comprises an L-shaped channel member(4) at one side of a penetrating portion between an outer wall and a middle slab(2); a glass wool(5) being placed through an inside of the channel member(4) and a side of the outer wall and being non-flammable and thermal; an L-shaped steel plate(3) having one side fixed on the side of the outer wall(1) and the other placed on a upper portion of the channel member(3) on which a foaming fireproof board is installed; a waterproof mortar(7) being applied to the upper portion of the slab(2); and a foaming fireproof sealant(8) for blocking a gap between the foaming fireproof board(6) and the waterproof mortar(7). Wherein, the products passed in the test(FS-012) for fireproof for two(2) hours by the disaster prevention inspection laboratory are used for the foaming fireproof board and the foaming fireproof sealant.
