One step prevents steel structure from corroding；Acrylic resin enamelled coating and fireproof coating layer, can be effectively by air and epoxy micaceous iron intermediate coat
Layer isolation, while fireproof coating layer can play fireproofing function.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Embodiment
In order to better understand and implement, describe the utility model in detail below in conjunction with the accompanying drawings.
Anti-corrosion steel structure, it includes steel structure body 1, and alumin(i)um zinc alloy layer 2, closing bottom are sequentially coated with the steel structure body
Enamelled coating 3, epoxy micaceous iron intermediate primer layers 4, acrylic resin enamelled coating 5, fireproof coating layer 6.Wherein it should be noted that fireproof coating
Layer 6 makees base-material using waterborne polymeric, then is equipped with the composition such as fire retardant compound system, fire-proof additive, refractory fibre, belongs to existing
There is the material in technology, do not make considered critical here.
The alumin(i)um zinc alloy layer 2 includes, the aluminium of 40~70 weight %, the zinc of 30~70 weight %, 0.1~10 weight %
Magnesium, the silicon not higher than 10 weight % and the iron not higher than 5 weight %；The alumin(i)um zinc alloy layer 2 is by its outside along described
Steel structure direction is equipped with outer layer, intermediate layer and diffusion layer (not shown) successively；The outer layer by ferro-aluminum phase and zinc-rich phase composition,
The intermediate layer is made of the ferro-aluminum compound of rich aluminium, and the diffusion layer is made of the iron mixed crystal of rich aluminium.Can be effectively to steel
Structure carries out cathodic protection.
The thickness of the alumin(i)um zinc alloy layer is 20~100 μm；The thickness of the seal coat layer is 15~20 μm；The ring
Oxygen cloud iron intermediate primer layers thickness is 20~50 μm；The acrylic resin thickness of paint layer is 20~50 μm；The fireproof coating layer
Thickness is 2mm.
Further illustrate this steel structure construction technology：
A) removing surface is carried out
It is clean to polishings such as the overlap on steel structure surface, splash, burrs；To greasy dirt, soluble-salt etc. existing for surface
Cleaned up with detergent or solvent；Weld grinding is smoother.It is final make component surface oil-free, it is pollution-free, without soluble-salt, weldering
Stitch it is smoother, without other welding slags, overlap, splash etc..
B) derusting by sandblasting
Manual sandblasting covers whole component surface, and nozzle is moved with constant velocity linear, whole before rear overlap joint together together
The spraying of a component should have certain order, from top to bottom, from one end of component to the other end successively sandblasting.In the process of sandblasting
In the uniformity coefficient of component sand blasted surface is visually inspected, so that it is determined that the required time, is sprayed in angle
Sandblasting should be carried out from different angles and the time should be slightly longer than commercial blast during sand.The surface very thick to some oxide skins, it is best
The low-angle in first spray, so can produce a less roughness except descale well, then be sprayed with wide-angle
Sand is to obtain correct surface extra coarse degree.
C) alumin(i)um zinc alloy layer is sprayed
Without special circumstances after derusting by sandblasting qualification, fire plating should be generally carried out immediately coated on steel structure.Application pressure before fire plating
Contracting air or banister brush clean component surface, make component surface it is pollution-free, without dust and other attachments.
D) seal coat layer, epoxy micaceous iron intermediate primer layers, acrylic resin enamelled coating, fireproof coating layer
Arc spray coatings are surface-treated with perching knife or sand paper before spraying, remove the particle or local big that surface loosens
Fusing point, it is ensured that arc spray coatings are tightly combined before spraying.Applied compression air is blown before every layer of spraying or banister brush is to upper track work
Sequence acceptance(check) component surface is purged, make component surface reach it is pollution-free, without dust and other attachments.Spray gun during construction
Must suitably, uniformly it be maintained at a distance from surface between 30-50cm, when spraying from top to bottom, is from left to right sprayed successively
Apply, walk when spraying that rifle is uniform, and covering 1/2 carries out operation per rifle.
Compared with prior art, the steel structure of the utility model, which is equipped with alumin(i)um zinc alloy layer, to carry out cathodic protection to steel structure；
Seal coat layer effectively can carry out Seal treatment to the gap of alumin(i)um zinc alloy layer；At the same time can using epoxy micaceous iron intermediate primer layers
Further to prevent steel structure from corroding；Acrylic resin enamelled coating and fireproof coating layer, can be effectively by air and epoxy micaceous iron
Between enamelled coating isolate, while fireproof coating layer can play fireproofing function.
The utility model is not limited to the above embodiment, if the various changes or deformation to the utility model do not take off
From the spirit and scope of the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to comprising these changes and deformation.
