The fire prevention of structure is particularly important.
Existing steel construction mainly has H profile steel, channel steel, angle steel, round steel and steel pipe etc., does not have fire protecting performance, or fire prevention
Performance is single, and when fire occurs, without flame retardant effect, high temperature causes steel construction intensity to be lower, and deformation causes the collapsing of building,
It is easily thermally conductive, it causes the intensity of a fire to contact, causes bigger loss, structure does not also help fire fighting, and fire protecting performance is poor.
Therefore, a kind of fire preventing steel structure is invented to be very necessary.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of fire preventing steel structure, is deposited with solving existing steel construction
Do not having fire protecting performance or fire protecting performance is single, fire-retardant effect resistant to high temperatures is poor, easily-deformable collapsing, easily thermally conductive to cause intensity of a fire string
Even, it is unfavorable for putting out a fire, comprehensive fire protecting performance difference is thus the problem of causing bigger loss.A kind of fire preventing steel structure, including structure sheaf,
Interlayer, external coating, cavity, inner coating, through-hole and conduit, the interlayer press from both sides between structural layers, and rectangular with structure sheaf composition
It is whole；The external coating is coated in the outer surface of structure sheaf and interlayer composition cuboid；The cavity is in steel construction entirety
The heart, and bottom connects outer water tube by conduit；The inner coating is coated on the wall of cavity；The through-hole is located at the interior of structure sheaf
Several are arranged in portion, and are connected to cavity；The conduit is welded on the bottom of structure sheaf.
The structure sheaf uses " well " word structural steel and iron, inside surround cavity, increase steel construction intensity, be conducive to fill
Auxiliary material enhances fire protecting performance.
The interlayer uses mineral fiber tilesn, and through screw on structure sheaf, not only increases the strong of steel construction entirety
Degree, and be conducive to anti-flaming thermal-insulation, reduce fire spreading.
The external coating uses refractory cement, and its thickness is greater than 7 millimeters, and thermal resistance of preventing fires reduces heat-conductive characteristic, improves
Steel structure fireproofing performance.
Inner coating on the cavity wall uses paint film, and water is filled in cavity, reduces the temperature of steel construction, passes through setting
Paint film, water leakage and corrosion steel construction, enhance the durable and fire resisting of steel construction, prevent deformation from collapsing, and are conducive to improve fire prevention
Safety.
The through-hole is connected to cavity to outside, and diameter is 2 to 5 millimeters, and its internal filling paraffin, when a fire,
Steel construction is heated, the paraffin melted by heat in through-hole, and the intracorporal water outflow of chamber or ejection increase the fire fighting performance of steel construction, have
Conducive to fire prevention.
The conduit connection cavity and fire fighting bolt are filled the water by conduit into cavity when fire occurs, and via through holes spray water again
It projects, is conducive to put out a fire.
Compared with prior art, the utility model has the following beneficial effects:
1. the setting of the structure sheaf of the utility model, interlayer and cavity is conducive to fill out by interlayer and cavity increase
Fill material, anti-flaming thermal-insulation, and prevent steel construction because temperature it is excessively high caused by the intensity of a fire series winding and steel construction intensity
Reduction causes cave-in accident.
2. the external coating of the utility model and internally coated setting are conducive to carry out anti-flaming thermal-insulation by external coating,
High fire cause thermal damage caused by steel construction is reduced convenient for storage water by inner coating protection structure sheaf, is increased
Strong fire safety.
3. the setting of the through-hole and conduit of the utility model, through-hole is melt through when being conducive to occur fire, in cavity
Water outflow sprays, and puts out a fire, carries out conveying water for fire extinguishing by conduit.
