Summary of the invention
The present invention is directed to each application aspect overlap joint confusion in the prior art, so that the due function of each application aspect can not get bringing into play fully at the reparation weld, the high-temperature soldering process of steel plate can be destroyed the complete shortcomings such as coating of application, a kind of stability and high efficiency is provided, so that the function of each application aspect is brought into play fully, welding process is not destroyed the stepped coating repairing method for corrugated steel web plate of coating structure.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Stepped coating repairing method for corrugated steel web plate comprises the following steps:
Step a: at distance welding central point 20-300mm place each coating is stacked gradually to be coated with and be contained on the Wavelike steel webplate, each coating becomes greatly successively to the distance of welding central point, forms step-like coating;
Step b: adhesive plastic protective film is pasted on the Wavelike steel webplate surface of the coating after will solidifying and not application;
Step c: Wavelike steel webplate to be welded is transported to the job site carries out welded and installed;
Steps d: the plastic sheeting on the Wavelike steel webplate surface that welded and installed is complete removes;
Step e: each coating of application that on the repair surface of Wavelike steel webplate, superposes successively so that each coating on the repair surface with solidify after coating corresponding overlap joint one by one;
Step f: the monolithic floor surface to the complete Wavelike steel webplate of application carries out anticorrosive coating, forms one deck corrosion-inhibiting coating.
Step g: the welding point reparation detects.
As preferably, each coating is 20-150mm to the distance of welding central point among the described step a.Above-mentioned design has been avoided may to the destruction of application aspect generation, being conducive to guarantee the fully performance of each coating layer function, to reach preferably Expected Results effectively in the process of high-temperature soldering steel plate.
As preferably, each layer coating layer thickness on the repair surface among the described step e is the 100%-130% of actual each coating layer thickness.Said method has moderately been thickeied the thickness of the coating layer on the repair surface, has effectively strengthened the antiseptic property of repair place, so that the state of repair place is more stable, has guaranteed the actual effect of coating.
As preferably, among the described step e on the repair surface ground floor coating of application be anticorrosive paint.Above-mentioned design has improved the whole antiseptic property of Wavelike steel webplate, has guaranteed the quality of application coating on Wavelike steel webplate and the Wavelike steel webplate, has improved whole stability.
The present invention is owing to adopted above technical scheme, has significant technique effect: utilize and adopt stepped coating repairing method at Wavelike steel webplate, so that the function of each application aspect is brought into play fully, and welding process is not destroyed the coating structure on the Wavelike steel webplate repair surface, add the antiseptic property that thick coating has been strengthened the repair place effectively in repair surface, so that the state of repair place is more stable, effectively improved the whole antiseptic property and stability of Wavelike steel webplate.
