Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into the model of present invention protection
Enclose.
Embodiments provide the construction method of methyl methacrylate road surface coating, including:
S1 plate-girder roof handling:
Clear up plate-girder end face before construction and concrete laitance is carried out grinding process, after the concrete laitance polishing on surface,
Cleaning laitance.
In this step, owing to methyl methacrylate coating layer thickness is less than 2.5mm, thinner thickness.Methyl methacrylate
The substantially full backup plate top surface of the beam flatness of the flatness of ester is controlled, so plate-girder roof handling is the most important.Meanwhile, in order to protect
Card methyl methacrylate coating is combined closely with bridge floor, needs to be cleaned out by plate-girder end face and enter concrete laitance before construction
Row grinding process.The on-the-spot grinding apparatus used is two-sided polisher.After the concrete laitance polishing on surface, will be floating with aerator
Slurry is cleaned out.
S2 priming coat roller coating:
Bridge floor cleaning, be dried without hydrops on the premise of, use cylinder to carry out slowly uniformly brushing along bridge floor, brushing completes
Rear placement, dry in the sun are to being dried；
In this step, must assure that bridge floor cleaning before priming coat construction, be dried without hydrops.Priming coat claims transparency emulsion
Shape, material is specialized factory's finished product material, it is not necessary to do any process, directly uses cylinder to brush along bridge floor during construction, brushing
Time should be the most uniform, it is to avoid holiday.This priming coat acts primarily as waterproof, caulking joint and cementation.Placement, dry in the sun after having brushed
6h-12h is to being dried.
S3 methyl methacrylate coating is constructed:
Methyl methacrylate coating, based on methyl methacrylate material, is subsequently adding appropriate firming agent and solvent；
Priming coat carries out methyl methacrylate coating construction after drying, and this coating construction point two-layer is constructed, bottom
Use the mode of blade coating, thickness 1-1.5mm；Surface layer uses the mode of spraying, thickness 1mm.
In this step, methyl methacrylate coating is according to methyl methacrylate: firming agent: solvent=50:1:1 ratio
Example is prepared.
Operated by professional during bottom blade coating, methyl methacrylate coating be poured on bridge floor according to consumption,
Workmen strikes off by floating rule feeding.
Bottom has been constructed and has been carried out the spraying application of surface layer after 2h, the uniformity of priority control spraying in work progress.Face
Layer spraying uses spray gun to carry out, and notes protection adjacent structure thing, prevent from spraying on other adjacent structure things by mistake in spraying process.
S4 inspection of quality.
At present, there is no the inspection of quality specification of methyl methacrylate coating construction, be that " urban road is colored with reference to specification
