Description

The Fire-proof steel plate device

The utility model relates to a kind of fire proofing material, particularly relates to a kind of Fire-proof steel plate device.

The roof in general large-area factory building or house directly is subjected to the solar radiation of permanent time, can make thermal source constantly be distributed to indoor and generation high temperature, so in order to reduce indoor temperature, the top layer in present large-area factory building, house all is erected with the Metallic corrugated sheet of a tool isolation layer.The flame isolation layer that directly burns of up climbing sharply when preventing fire, therefore, the isolation layer bottom must be covered with a fireprotection layer again to isolate burning things which may cause a fire disaster; Please cooperate consult shown in Figure 1, it is the schematic diagram of Fire-proof steel plate in the past, this insulating board 10 is to be one or three sheet buildings, upper strata 11 is a Metallic corrugated sheet, lower floor 13 makes for metal plate and colored cloth etc., (Polyurethane PU) waits expanded material, and upper and

lower layer

11,13 close adhesion are integral with polyurethane for 12 in middle level.The limit end that mountain peak 111 is established on its upper strata 11 has interior curved antelabium 112, the hypotenuse 131,132 that lower floor's 13 and arranged on left and right sides also have two complementations and be arranged in parallel, therefore, when two heat insulation plates during by mountain peak 111,113 one-tenth overlapping setting up, relend a bolt 14 and placed upper and

lower layer

11,13 and middle level 12 by mountain peak 111 and be fixed on the girder steel, and interior curved antelabium 112 and two mountain peaks 111,113 form to press closely because of the bolt application of force screws and connect airtight.In addition, the hypotenuse 131,132 of two insulating boards, 10 bottoms also has parallel shrinkage joint, an inclined-plane, watched by the bottom surface then only having lines to exist, but not therefore bigger gap, makes it have better visual effect.

Insulating board 10 in the past is by above-mentioned mode, and what can make 12 in upper and

lower layer

11,13 and heat insulation middle level is bonded with preferable adaptation and visual effect, still, in fact also has following disappearance:

One. because these bolt 14 heads are exposed to the outside of insulating board 10, be subject to long-term exposing to the sun and rain and oxidation corrosion, and bolt 14 also can be because of the slit produces capillarity with insulating board 10 joining places, and rainwater just can infiltrate within doors via the slit, produce drainage within doors and make.

Two. in addition, when the excessive temperature differentials of indoor and outdoor, airborne moisture and moisture can infiltrate the lap-joint of two insulating boards 10, and are infiltrated within doors and condensed into water droplet by two hypotenuses, 131,132 joining places, cause indoor humidity, and make the effect of heat insulation structure material have a greatly reduced quality.

Main purpose of the present utility model is to overcome the deficiencies in the prior art, and provide a kind of and can prevent fires, prevent bolt corrosion, and the Fire-proof steel plate device of anti-joining place clearance leakage.

Secondary objective of the present utility model is to provide a kind of airborne moisture and moisture of can blocking to infiltrate within doors, has the Fire-proof steel plate device of preferable airtight effect.
