Abstract
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.

A built-up inner floating ceiling, equipped with instant fire extinguishing devices, for use in an oil storage tank, comprising:
- a skeleton of radial structure, said skeleton consisting of H-shaped radial beams and peripheral beams which are bolted together;
- foam plastic buoys, fitted into the grooves of said H-shaped beams and pressed by cover plates on top, and in contact with metallic nets provided beneath;
- girded girders, bolted into an integral body and supported by supporting legs;
- said radial beams being uniformly arranged at equal angular intervals, each with one end bolted to a girder and the other end bolted to a centre disk which is fitted in the centre of said inner floating ceiling;
- further comprising anti-rotational wires and connecting wires, fitted between said cover plates and the top of the tank, and fire-proof foam plates, tongue-shaped seals and fixing plates for said seals, all fitted round the periphery of said ceiling;
- the peripheral ones among said foam plastic buoys being made into a hollow structure, to form hollow chambers along and close to the periphery in said peripheral plastic buoys, which hollow chambers are used to place instant fire extinguishing devices.
