A kind of built-up inner floating ceiling, equipped with instant fire extinguishing devices, for use in an oil storage tank, consisting of a skeleton formed by girders, cover plates, radial beams, peripheral beams, plastic buoys, plate fixing beams, etc., said plastic buoys being made into a hollow structure, forming hollow chambers, where steel vessels filled with high-pressure inert gas are placed, said steel vessels being connected through connecting pipes fitted with left-handed screw caps and lock washers. As said screw caps are made of a low melting point material, in case of a fire, the will be melted at once, thus releasing the inert gas in said vessels, and extinguishing the fire.
