Fire-proof plate.
Fireproof plugging structure below the utility model raised flooring has the advantages that compared with prior art：
Fireproof plugging structure combination rolling screen door below the utility model raised flooring is isolated to indoor fire safety subregion
And fireproof blocking, plugging structure is combined using lightgage steel joist frame structure with rock wool and fire-proof plate so that structure can be with pipeline
It is adapted, is blocked at gap using fireproof gum to greatest extent, closure seal is higher；Keel frame fire proof construction uses two
The keel frame of laid out in parallel, middle vacant, the compound heat-insulation system with the keel frame formation multi-medium-layer of both sides, fire prevention effect
Fruit is more preferably；Plugging structure can be adjusted flexibly keel frame according to the intricately condition of pipe installation, pipeline is entered to be detachably fixed
Row across setting, structure is easy to assembly, and construction cost is relatively low, construct it is more flexible, be particularly suitable for use in pipeline and electromechanical pipeline it is more
Fireproof blocking below raised flooring；When overhauling construction in the later stage, peace tears convenient open, greatly reduces operational procedure and construction week
Phase, reduce construction cost.
The fireproof plugging structure below raised flooring of the present utility model is described further below in conjunction with the accompanying drawings.
