Step 8, and conserve to predetermined strength, construction is finished.
In the present embodiment, step between the step 7 and step 8, is also included, in the outer protection structure component of steel construction
Plaster or sprayed fire proofing coating at outside scene.
In the present embodiment, the fireproof coating be super-thin steel structure fire-proof paint or thin section steel structure fire-resisting paint or
Person is mineral wool class Building Fire Protection insulating moulding coating.
In the present embodiment, within the super-thin steel structure fire-proof paint refers to 3 mm of coating layer thickness (containing 3 mm), decoration
Preferably, during high temperature, expansion foams effect, fire-resistant coating for steel structure of the fire endurance typically within 2 h.Such steel construction is prevented
Fiery coating is generally solvent-based system, with spies such as superior bond strength, weather-proof water-tolerant, good leveling property, good decorative properties
Point；Slowly expanded foamed when by fire form fine and close hard fire proof heat-insulation layer, the fireprotection layer has very strong flameproofed impact-resistance,
The temperature rise of steel, effective protection steel beam column are delayed.Superthin expansion steel structure fireproof coating construction can adopt spraying, brush or
Roller coat, is generally used on construction steel structure of the fire endurance requirement within 2 h.Occur in that fire resistance meets or exceeds
The super-thin steel structure fire-proof paint new varieties of 2 h, it are mainly with the polymethacrylates or epoxy resin of special construction
With compoundings such as amino resins, chlorinated paraffins as base material binding agent, high polymerization degree APP, Bis(pentaerythritol), trimerization is accompanied by
Cyanamide etc. is fire protection flame retarding system, adds the inorganic fire proof materials such as titanium dioxide, wollastonite, with 200# solvent naphthas as solvent is compound
Into.Various lightweight steel constructions, rack etc. are more to carry out flameproof protection using the type fireproof coating.As such fireproof paint coating surpasses
Thin so that usage amount thicker type, thin section steel structure fire-resisting paint greatly reduce, so as to reduce engineering total cost, tie steel again
Structure has obtained effective flameproof protection, and flameproof effect is fine.
The thin coated type steel structure fire-proof paint refers to coating layer thickness more than 3mm, less than or equal to 7 mm, has certain decoration effect
Really, during high temperature, expansion is thickened, fire-resistant coating for steel structure of the fire endurance within 2 h.This kind of fire-resistant coating for steel structure is usually
Make base material with suitable waterborne polymeric, then be equipped with the composition such as fire retardant compound system, fire-proof additive, refractory fibre, which is prevented
Fiery principle is with ultrathin.To this kind of fireproof coating, it is desirable to the waterborne polymeric of selection steel substrate must be had good adhesive force,
Durability and resistance to water.Its dicoration is inferior to super-thin steel structure fire-proof paint, general fire resisting pole better than thicker fireproof coating
Limit is within 2 h.Therefore it is commonly used in the steel structure fireproof protection engineering less than 2 h fire endurances, frequently with spraying application.?
One period occupies very big ratio, but the appearance with super-thin steel structure fire-proof paint, and its market share is gradually substituted.
In the present embodiment, the thicker fire-resistant coating for steel structure refers to coating layer thickness more than 7 mm, less than or equal to 45 mm,
Face in pelletized form, density are less, and thermal conductivity is low, fire-resistant coating for steel structure of the fire endurance in 2 more than h.Due to thicker fireproof coating
Composition mostly be inorganic material, therefore its fire protecting performance is stable, permanence operation preferably, but the granule of its coating composition compared with
Greatly, appearance of coat out-of-flatness, affects the overall appearance of building, is therefore mostly used for structure concealed work.Such fireproof coating exists
Using material granular surface in fire, density is less, thermal conductivity is low or coating in material heat absorptivity, delayed the temperature of steel
Rise, protect steel.This kind of fireproof coating is (such as waterglass, Ludox, phosphalugel, fire resisting water with suitable inorganic binder
Mud etc.), then be equipped with inorganic light weight thermal insulation aggregate materials (such as expanded perlite, expanded vermiculite, Hai Baoshi, floating bead, flyash etc.),
Fire-proof additive, chemical agent and reinforcing material (such as alumina silicate fibre, rock wool, ceramic fibre, glass fibre etc.) and filler etc.
Mixed preparing is formed, with lower-cost advantage.Construction is frequently with spraying, it is adaptable to which fire endurance is required 2 more than h's
The hidden steel construction of indoor and outdoor, high-rise full steel structure and multi storied factory building steel construction.Such as：The post of high-rise civil building, general industry with
The fire endurance for supporting the post of multilamellar in civil buildings all should reach 3 h, need to adopt the thicker fireproof coating protection.
In the present embodiment, the mineral wool class Building Fire Protection insulating moulding coating is after thick coated type architectural fireproof paint Margarita
Series of rocks are arranged, the another important fireproof coating series after magnesia oxychloride cement series fireproof coating, still belong to blank, it and perlite class
Fireproof coating is compared, and which is mainly characterized by play potentiation as the mineral fibres of thermal insulating filling to strength of coating, can answer
For the multiple building that is regional or often being shaken of earthquake, and fire prevention, the effect of heat-insulated, sound-absorbing can be played.Mineral wool class is built
Building fire-proof and thermal-insulation coating mainly has mineral fibres fire-proof and thermal-insulation coating, thermal insulating filling, and its main component is mineral wool, binding material
Usually cement, is constructed using dry spraying at the scene, i.e., reinstate pressure-air and convey with binding material one after fiber is dispersed through
To nozzle, then with the high atomization water mixing jetting being distributed in around spout to surfaces to be coated.It is obtained in that density is less
Coating, so as to mitigate the weight of whole building thing, reduces building loading.Foreign countries are widely used quick-dry type mineral wool class and prevent
Fiery coating, when the construction site of execution conditions difference uses, short have the advantages that easy construction, low cost, drying time.
